    The burden and epidemiology of Mycoplasma pneumoniae (Mp) among U.S. children (<18 years) hospitalized with community-acquired pneumonia (CAP) are poorly understood. In the Etiology of Pneumonia in the Community (EPIC) study, we prospectively enrolled 2254 children hospitalized with radiographically-confirmed pneumonia from January 2010-June 2012 and tested nasopharyngeal/oropharyngeal swabs for Mp using real-time polymerase chain reaction (PCR). Clinical and epidemiological features of Mp-PCR-positive and -negative children were compared using logistic regression. Macrolide susceptibility was assessed by genotyping isolates. In the EPIC study, 182(8%) children were Mp-PCR-positive (median age: 7 years); 12% required intensive care and 26% had pleural effusion. No in-hospital deaths occurred. Macrolide resistance was found in 6/169(4%) isolates. Of 178(98%) Mp-PCR-positive children tested for co-pathogens, 50(28%) had ≥1 co-pathogen detected. Variables significantly associated with higher odds of Mp detection included age {10-17 years [adjusted odds ratio (aOR): 7.9 (95% confidence interval (CI): 4.5-13.6)] and 5-9 years [aOR: 4.8 (CI: 2.9-7.8)] vs. 2-4 years}, outpatient antibiotics ≤5 days pre-admission [aOR: 2.3 (CI: 1.5-3.4)], and co-pathogen detection [aOR: 2.1 (CI: 1.3-3.1)]. Clinical characteristics often seen included hilar lymphadenopathy, rales, headache, sore throat, and decreased breath sounds. Usually considered as a mild respiratory infection, M. pneumoniae was the most commonly detected bacteria among children ≥5 years hospitalized with CAP; one-quarter of whom had co-detections. Although associated with clinically non-specific symptoms, there was a need for intensive care support in some cases. M. pneumoniae should be included in the differential diagnosis for school-aged children hospitalized with CAP.

    Purpose: To evaluate the independent prognostic impact of the chest radiograph for mortality from community-acquired pneumonia requiring hospitalization. Methods: Chest radiographs of 67 patients with hospital-treated community-acquired pneumonia were analyzed with regard to the prognostic implications of radiographic patterns, extent and density of infiltrates, and its evolution during treatment. Results: Non-survivors had a significantly higher extent of infiltrates (p=0.008), density of infiltrates (p=0.05), and radiographic spread during follow-up within 48-72 hours (p=0.0001). In multivariate analysis, persistent or progressive infiltrates were associated with a 47fold increase, and persistent or progressive density of infiltrates with an 18fold increase in risk of mortality. The presence of both parameters could correctly predict 96% of survivors and 90% of non-survivors. Conclusions: The chest radiograph is an independent predictor of the severity of pneumonia. Both persistent or progressive infiltrates and persistent or progressive density of infiltrates are independently associated with mortality from community-acquired pneumonia. (orig.) [de

    To ascertain the causative organisms of community acquired pneumonia (Cap) in Jordanian patients requiring hospital admission. A prospective study of both adults and children admitted to Princess Basma and Princess Rahma Teaching Hospitals in Irbid, Jordan with a diagnosis of CAP over a 6-month period from April to October 2002. A total of 35 adult patients were admitted with a mean age of 47 years, and 63 children with a mean age of 3 years. A pathogen was isolated from 25 (71%) adults, and from 17 (27%) children, and sputum cultures gave the best diagnostic yield. In adults Streptococcus pneumoniae was the most common isolate (26%), followed by Chlamydia pneumoniae (23%), Haemophilus influenzae (17%), Mycoplasma pneumoniae (9%), and Legionella pneumophila and Klebsiella pneumoniae (6%) each. Seven of the 9 gram negative isolates were from patients with some co morbid illness. While in children, Chlamydia pneumoniae was the most common (14%), followed by Mycoplasma pneumoniae (6%), and Streptococcus pneumoniae, Haemophilus influenzae, and Pseudomonas aeruginosa (3%) each. Streptococcus pneumoniae and atypical microorganisms are the most common cause of CAP in previously healthy adults; while in those with associated co morbid illness, gram negative organisms are the likely cause. In children, the overall detection rate of causative organisms was low with atypical microorganisms being the most common. (author)

    This article not only reviews the essential aspects of community-acquired pneumonia for daily clinical practice, but also highlights the controversial issues and provides the newest available information. Community-acquired pneumonia is considered in a broad sense, without excluding certain variants that, in recent years, a number of authors have managed to delineate, such as healthcare-associated pneumonia. The latter form is nothing more than the same disease that affects more frail patients, with a greater number of risk factors, both sharing an overall common approach.

    Information on the influence of pre-hospital antibiotic treatment on the causative organisms, clinical features and outcomes of patients with community-acquired pneumonia (CAP) remains scarce. We performed an observational study of a prospective cohort of non-immunosuppressed adults hospitalized with CAP between 2003 and 2012. Patients were divided into two groups: those who had received pre-hospital antibiotic treatment for the same episode of CAP and those who had not. A propensity score was used to match patients. Of 2179 consecutive episodes of CAP, 376 (17.3%) occurred in patients who had received pre-hospital antibiotic treatment. After propensity score matching, Legionella pneumophila was more frequently identified in patients with pre-hospital antibiotic treatment, while Streptococcus pneumoniae was less common (p sensitivity and specificity of the pneumococcal urinary antigen test for diagnosing pneumococcal pneumonia were similar in the two groups. Patients with pre-hospital antibiotic treatment were less likely to present fever (p 0.02) or leucocytosis (p 0.001). Conversely, chest X-ray cavitation was more frequent in these patients (p 0.04). No significant differences were found in the frequency of patients classified into high-risk Pneumonia Severity Index classes, in intensive care unit admission, or in 30-day mortality between the groups. In conclusion, L. pneumophila occurrence was nearly three times higher in patients who received pre-hospital antibiotics. After a propensity-adjusted analysis, no significant differences were found in prognosis between study groups. Pre-hospital antibiotic use should be considered when choosing aetiological diagnostic tests and empirical antibiotic therapy in patients with CAP. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical Microbiology and Infectious Diseases.

    We report the history of a 38-year-old male native of Sri Lanka admitted to the emergency ward because of chest pain and shortness of breath. On physical and radiographic examination a bilateral predominantly right-sided pneumonia was found. The patient was admitted to the medical ICU and an antibiotic regimen with amoxicillin/clavulanic acid and erythromycin was initiated. Shortly afterwards septic shock developed. The patient was intubated and received high doses of catecholamines. He died 30 hours after admission to the hospital. Cultures from sputum, tracheal aspirate and blood grew Acinetobacter baumanni. Acinetobacter is an ubiquitous gram-negative rod with coccobacillary appearance in clinical specimens, that may appear gram-positive due to poor discoloration on Gram-stain. It is a well known causative agent of nosocomial infections, particularly in intensive care units. Community-acquired pneumonias, however, are quite rare. Sporadic cases have been reported from the US, Papua-New Guinea and Australia. Interestingly, these pneumonias are fulminant and have a high mortality. Chronic obstructive lung disease, diabetes, and tobacco and alcohol consumption appear to be predisposing factors. Due to the rapid course and poor prognosis, prompt diagnosis and adequate antibiotic treatment are indicated. Antibiotics use for community-acquired pneumonias, such as amoxicillin/clavulanic acid or macrolides, are not sufficient. Appropriate antibiotics for the initial treatment of suspected Acinetobacter infections include imipenem and carboxy- and ureidopenicillins combined with an aminoglycoside.

    Recent studies suggest older patients hospitalized for community-acquired pneumonia are at risk for new-onset cognitive impairment. The characteristics of long-term cognitive impairment after pneumonia, however, have not been elucidated. To characterize long-term cognitive impairment among adults of all ages hospitalized for community-acquired pneumonia. Prospective cohort study. Adults without severe preexisting cognitive impairment who were hospitalized with community-acquired pneumonia. At enrollment, we estimated baseline cognitive function with the Short Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE). At 2- and 12-month follow-up, we assessed cognition using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and tests of executive function, diagnosing cognitive impairment when results were ≥ 1.5 standard deviations below published age-adjusted means for the general population. We also identified subtypes of mild cognitive impairment using standard definitions. We assessed 58 (73%) of 80 patients who survived to 2-month follow-up and 57 (77%) of 74 who survived to 12-month follow-up. The median [range] age of survivors tested was 57 [19-97] years. Only 8 (12%) had evidence of mild cognitive impairment at baseline according to the Short IQCODE, but 21 (38%) at 2 months and 17 (30%) at 12 months had mild cognitive impairment per the RBANS. Moderate-to-severe cognitive impairment was common among adults ≥ 65 years [4/13 (31%) and 5/13 (38%) at 2 and 12 months, respectively] but also affected many of those cognitive domains affected one-third of patients ≥ 65 years old and 20% of younger patients, and another third of survivors had mild cognitive impairment.

    Little data is available on the resource utilisation of patients admitted with Community-Acquired Pneumonia (CAP) in Ireland. A retrospective review of 50 randomly-selected patients admitted to Beaumont Hospital with CAP was undertaken. The mean length of stay of patients with CAP was 12 days (+\\/- 16 days). All patients were emergency admissions, all had a chest x-ray, a C-reactive protein blood test, and occupied a public bed at some point during admission. Common antimicrobial therapies were intravenous (IV) amoxicillin\\/clavulanic acid and oral clarithromycin; 60% received physiotherapy. The estimated mean cost of CAP per patient was €14,802.17. Costs arising from admission to hospital with CAP are substantial, but efforts can be undertaken to ensure that resources are used efficiently to improve patient care such as discharge planning and fewer in-hospital ward transfers

    The sustained health-related quality-of-life of patients surviving community-acquired pneumonia has not been accurately quantified. The aim of the current study was to quantify differences in health-related quality-of-life of community-dwelling elderly with and without community-acquired pneumonia during a 12-month follow-up period. In a matched cohort study design, nested in a prospective randomized double-blind placebo-controlled trial on the efficacy of the 13-valent pneumococcal vaccine in community-dwelling persons of ≥65 years, health-related quality-of-life was assessed in 562 subjects hospitalized with suspected community-acquired pneumonia (i.e. diseased cohort) and 1145 unaffected persons (i.e. non-diseased cohort) matched to pneumonia cases on age, sex, and health status (EQ-5D-3L-index). Health-related quality-of-life was determined 1-2 weeks after hospital discharge/inclusion and 1, 6 and 12 months thereafter, using Euroqol EQ-5D-3L and Short Form-36 Health survey questionnaires. One-year quality-adjusted life years (QALY) were estimated for both diseased and non-diseased cohorts. Separate analyses were performed for pneumonia cases with and without radiologically confirmed community-acquired pneumonia. The one-year excess QALY loss attributed to community-acquired pneumonia was 0.13. Mortality in the post-discharge follow-up year was 8.4% in community-acquired pneumonia patients and 1.2% in non-diseased persons (p pneumonia patients, compared to non-diseased persons, but differences in health-related quality-of-life between radiologically confirmed and non-confirmed community-acquired pneumonia cases were not statistically significant. Community-acquired pneumonia was associated with a six-fold increased mortality and 16% lower quality-of-life in the post-discharge year among patients surviving hospitalization for community-acquired pneumonia, compared to non-diseased persons.

    Community-acquired pneumonia (CAP) is a major cause of death in the elderly. The age-related increase in comorbid illnesses plays a part but the effect of aging on the immune response may be equally important. We aimed to evaluate patients with CAP for evidence of a muted response to infection in elderly patients admitted to hospital compared with a younger patient group.

    One of the strategies for the rational use of antibiotics is the use of the score for community-acquired pneumonia (CAP Score). This instrument clinically evaluates patients with community-acquired pneumonia, thereby facilitating decision making regarding the early and safe withdrawal of antibiotics. To generate a translation and cross-cultural adaptation of the Community-Acquired Pneumonia (CAP) Score questionnaire in Spanish. Authorization for cross-cultural adaptation of the Community-Acquired Pneumonia (CAP) Score questionnaire was obtained; the recommendations of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) and the European Organisation for Research and Treatment of Cancer (EORTC) were carried out through the following stages: forward translation, reconciliation, backward translation, harmonization, obtaining a provisional questionnaire, and applying the questionnaire in a pilot test. The pilot test was conducted at a second-level public hospital in Bogotá after the study was approved by the ethics and research institutional boards. The changes suggested by the forward translators were applied. There were no discrepancies between the backward and forward translations, consequently, no revisions were necessary. Five items had modifications based on suggestions made by eleven patients hospitalized with a diagnosis of community-acquired pneumonia during the pilot test. A Spanish version of the Community-Acquired Pneumonia (CAP) Score was crossculturally adapted and is now available.

    The impact of obesity on the outcome of pneumonia is uncertain. We retrospectively identified 266 hospitalized patients with proven pneumococcal or Haemophilus community-acquired pneumonia who had at least one body mass index (BMI, kg/m²) value documented in the 3 months before admission. Patients were classified as underweight (BMI values and BMI categories with the mortality at 30 days after admission for pneumonia was investigated. Increasing BMI values were associated with reduced 30-day mortality, even after adjustment for significant covariates (odds ratio 0.88, confidence interval 0.81-0.96; p<0.01). There was a significant trend towards lower mortality in the overweight and obese (non-parametric trend, p=0.02). Our data suggest that obesity may exert a protective effect against 30-day mortality from community-acquired bacterial pneumonia. Copyright © 2010 International Society for Infectious Diseases.

    The diagnosis of community-acquired pneumonia (CAP) is often not possible based only on the clinical symptoms and biochemical parameters. For every patient with the suspicion of CAP, a chest radiograph in two planes should be carried out. Additionally, a risk stratification for the decision between outpatient therapy or hospitalization is recommended. Based on the evaluation of the different radiological patterns as well as their extent and distribution, a rough allocation to so-called pathogen groups as well as a differentiation between viral and bacterial infections are possible; however, because different pathogens cause different patterns an accurate correlation is not feasible by relying purely on imaging. The radiological findings serve as proof or exclusion of pneumonia and can also be used to evaluate the extent of the disease (e.g. monolobular, multilobular, unilateral or bilateral). In cases of prolonged disease, suspicion of complications (e.g. pleural effusion or empyema, necrotizing pneumonia or abscess) or comorbid conditions (e.g. underlying pulmonary or mediastinal diseases) computed tomography is an important diagnostic tool in addition to chest radiography. Ultrasound is often used to diagnose pleural processes (e.g. parapneumonic effusion or pleural empyema). (orig.) [de

    2006-01-01

    Full Text Available Legionella pneumophila is a common cause of sporadic community-acquired pneumonia, but culture-proven legionellosis is rarely diagnosed. There is no laboratory test for Legionnaires' disease that can detect all patients with the disease. Culture is the standard diagnostic method and should be initiated as soon as possible in suspected cases. We describe a rare case of community-acquired pneumonia caused by L. pneumophila serogroup 6. A 77-year-old man was admitted to a tertiary care hospital because of high fever, productive cough, and progressive dyspnea. Chest radiography showed bilateral pneumonia, which led to respiratory failure necessitating mechanical ventilatory support. Despite antibiotic therapy, his condition continued to deteriorate and acute renal failure also developed. Urine was negative for L. pneumophila. Culture of the sputum yielded L. pneumophila serogroup 6, although there was no elevation of the serum antibody titer. Pneumonia resolved gradually and he was extubated after treatment with levofloxacin followed by erythromycin. L. pneumophila other than serogroup 1 should be included in the differential diagnosis of patients with suspected atypical community-acquired pneumonia.

    2014-03-01

    Community-acquired pneumonia (CAP) is a common infection in developed countries and causes a large number of hospital admissions and deaths. In recent years, the incidence of this disease has increased, caused by progressive population aging. Following the introduction of the conjugate vaccine against Streptococcus pneumoniae, there have been significant epidemiological changes that require close monitoring because of the possible emergence of new patterns of resistance. This article aims to review the role of ceftaroline fosamil, a new parenteral cephalosporin with antibacterial activity against Gram-negative and Gram-positive pathogens, in the treatment of pneumonia. Several in vitro and in vivo studies have shown the efficacy of ceftaroline fosamil against penicillin-resistant S. pneumoniae and methicillin-resistant Staphylococcus aureus (MRSA). Additionally, ceftaroline has shown similar efficacy and safety to ceftriaxone in the treatment of community-acquired pneumonia with severe prognosis (prognostic severity index III and IV) in two phase III clinical trials. Although a non-inferiority design was used for these clinical trials, some data suggest a superior efficacy of ceftaroline, with earlier clinical response and higher cure rate in infections caused by S. pneumoniae, making this drug particularly interesting for critically-ill patients admitted to the intensive care unit. Ceftaroline may also be considered for empirical and directed treatment of MRSA pneumonia. Copyright © 2014 Elsevier España, S.L. All rights reserved.

    Full Text Available Background: Community-acquired pneumonia could be a life-threatening condition especially in elderly patients. The factors influencing the outcome in elderly patients are thought to be different from those in young adults. We compared the clinical and paraclinical profiles in elderly and nonelderly patients with community-acquired pneumonias. Methods: In this cross-sectional study, seventy nine patients who were hospitalized with community acquired pneumonia over a period of one year were included. Patients' medical records were reviewed; and data related to comorbid conditions, signs and symptoms, laboratory and radiographic findings were gathered using a checklist. Results: The clinical features, laboratory parameters and complications from pneumonia were almost similar in 41 elderly (group I, age ≥65years and 38 young (group II, age<65years subjects. Delirium was seen more in elderly group (p=0.05. The average body temperature and pulse rate were significantly higher in nonelderly group. Sixty one percent of elderly patients and 21% of young patients have Po2 less than 60 (p=0.02. Smoking (29.1%, neurological disturbances (19%, congestive heart failure (15.2%, chronic obstructive pulmonary disease and diabetes mellitus (13.9% were associated comorbidities in both groups. In non elderly group, immune compromise and IV drug use were more common as underlying comorbid conditions. Two of three mortalities were due to elder patients. Conclusion: Community acquired pneumonia could have more serious clinical and abnormal laboratory features in the elderly than younger patients. Mortality rate may be higher in older patients. Comorbid conditions are frequently seen in both elderly and nonelderly patients with community acquired pneumonia, but IV drug use and immune compromise are more frequent in nonelderly patients.

    Community-acquired pneumonia (CAP) encompasses a broad spectrum of disease severity and may require outpatient, inpatient, or intensive care management. Successful treatment hinges on expedient delivery of appropriate antibiotic therapy tailored to both the likely offending pathogens and the severity of disease. This review summarizes key principles in starting treatment and provides recommended empiric therapy regimens for each site of care. In addition, we discuss the antimicrobial and anti-inflammatory role macrolides play in CAP, as well as specific information for managing individual CAP pathogens such as community-acquired methicillin-resistant Staphylococcus aureus and drug-resistant Streptococcus pneumoniae . We also examine several novel antibiotics being developed for CAP and review the evidence guiding duration of therapy and current best practices for the transition of hospitalized patients from intravenous antibiotics to oral therapy.

    Full Text Available BACKGROUND: Since healthcare-associated pneumonia (HCAP is heterogeneous, clinical characteristics and outcomes are different from region to region. There can also be differences between HCAP patients hospitalized in secondary or tertiary hospitals. This study aimed to evaluate the clinical characteristics of HCAP patients admitted into secondary community hospitals. METHODS: This was a retrospective study conducted in patients with HCAP or community-acquired pneumonia (CAP hospitalized in two secondary hospitals between March 2009 and January 2011. RESULTS: Of a total of 303 patients, 96 (31.7% had HCAP. 42 patients (43.7% resided in a nursing home or long-term care facility, 36 (37.5% were hospitalized in an acute care hospital for > 2 days within 90 days, ten received outpatient intravenous therapy, and eight attended a hospital clinic or dialysis center. HCAP patients were older. The rates of patients with CURB65 scores of 3 or more (22.9% vs. 9.1%; p = 0.001 and PSI class IV or more (82.2% vs. 34.7%; p < 0.001 were higher in the HCAP group. Drug-resistant pathogens were more frequently detected in the HCAP group (23.9% vs. 0.4%; p < 0.001. However, Streptococcus pneumoniae was the most common pathogen in both groups. The rates of antibiotic change, use of inappropriate antibiotics, and failure of initial antibiotic therapy in the HCAP group were significantly higher. Although the overall survival rate of the HCAP group was significantly lower (82.3% vs. 96.8%; p < 0.001, multivariate analyses failed to show that HCAP itself was a prognostic factor for mortality (p = 0.826. Only PSI class IV or more was associated with increased mortality (p = 0.005. CONCLUSIONS: HCAP should be distinguished from CAP because of the different clinical features. However, the current definition of HCAP does not appear to be a prognostic for death. In addition, the use of broad-spectrum antibiotics for HCAP should be reassessed because S. pneumoniae was most

    Neurological disorders in children highly affect the course of pneumonia, its outcome and the development of possible complications. The aim of the study was to reveal clinical and paraclinical features of community-acquired pneumonia in younger children with neurologic pathology infantile cerebral palsy. Under observation were 37 children with community-acquired pneumonia aged 1 to 3 years that suffered from spastic forms of infantile cerebral palsy. The comparison group consisted of 30 children with community-acquired pneumonia without any concomitant neurological pathology. The age of the children in the comparison and study groups was the same. The results of the study show that the presence of infantile cerebral palsy allow to relate the child to the risk group of respiratory pathology development. The course of community-acquired pneumonia in children affected by infantile cerebral palsy is characterized by rapid progression of symptoms and severity of the condition, and the clinical picture also has a number of characteristic features. Thus, cough, local physical data, classical laboratory signs of inflammation in the form of leukocytosis with neutrophil shift were noticed significantly less often in children with infantile cerebral palsy. The debut of the disease was often accompanied by bronchial obstruction, the inflammatory process was localized in the lower parts of the lungs and often matched the side of the neurologically affected part of the body. Children with cerebral palsy required a longer hospital-stay and a prolonged course of antibiotic therapy. Therefore, the risk of pneumonia in children with infantile cerebral palsy should be taken into account at the primary stage of medical care for the creation of preventive programs.

    Full Text Available Motoi Ugajin, Kenichi Yamaki, Natsuko Hirasawa, Takanori Kobayashi, Takeo Yagi Department of Respiratory Medicine, Ichinomiya-Nishi Hospital, Ichinomiya City, Japan Background: The credibility of prognostic indicators in nursing-home-acquired pneumonia (NHAP is not clear. We previously reported a simple prognostic indicator in community-acquired pneumonia (CAP: blood urea nitrogen to serum albumin (B/A ratio. This retrospective study investigated the prognostic value of severity indicators in NHAP versus CAP in elderly patients. Methods: Patients aged ≥65 years and hospitalized because of NHAP or CAP within the previous 3 years were enrolled. Demographics, coexisting illnesses, laboratory and microbiological findings, and severity scores (confusion, urea, respiratory rate, blood pressure, and age ≥65 [CURB-65] scale; age, dehydration, respiratory failure, orientation disturbance, and pressure [A-DROP] scale; and pneumonia severity index [PSI] were retrieved from medical records. The primary outcome was mortality within 28 days of admission. Results: In total, 138 NHAP and 307 CAP patients were enrolled. Mortality was higher in NHAP (18.1% than in CAP (4.6% (P<0.001. Patients with NHAP were older and had lower functional status and a higher rate of do-not-resuscitate orders, heart failure, and cerebrovascular diseases. The NHAP patients more frequently had typical bacterial pathogens. Using the receiver-operating characteristics curve for predicting mortality, the area under the curve in NHAP was 0.70 for the A-DROP scale, 0.69 for the CURB-65 scale, 0.67 for the PSI class, and 0.65 for the B/A ratio. The area under the curve in CAP was 0.73 for the A-DROP scale, 0.76 for the CURB-65 scale, 0.81 for the PSI class, and 0.83 for the B/A ratio. Conclusion: Patient mortality was greater in NHAP than in CAP. Patient characteristics, coexisting illnesses, and detected pathogens differed greatly between NHAP and CAP.

    To describe and compare the clinical characteristics, outcomes, and etiology of pneumonia among children hospitalized with community-acquired pneumonia (CAP) with neurologic disorders, non-neurologic underlying conditions, and no underlying conditions. Children children's hospitals. Neurologic disorders included cerebral palsy, developmental delay, Down syndrome, epilepsy, non-Down syndrome chromosomal abnormalities, and spinal cord abnormalities. We compared the epidemiology, etiology, and clinical outcomes of CAP in children with neurologic disorders with those with non-neurologic underlying conditions, and those with no underlying conditions using bivariate, age-stratified, and multivariate logistic regression analyses. From January 2010-June 2012, 2358 children with radiographically confirmed CAP were enrolled; 280 (11.9%) had a neurologic disorder (52.1% of these individuals also had non-neurologic underlying conditions), 934 (39.6%) had non-neurologic underlying conditions only, and 1144 (48.5%) had no underlying conditions. Children with neurologic disorders were older and more likely to require intensive care unit (ICU) admission than children with non-neurologic underlying conditions and children with no underlying conditions; similar proportions were mechanically ventilated. In age-stratified analysis, children with neurologic disorders were less likely to have a pathogen detected than children with non-neurologic underlying conditions. In multivariate analysis, having a neurologic disorder was associated with ICU admission for children ≥2 years of age. Children with neurologic disorders hospitalized with CAP were less likely to have a pathogen detected and more likely to be admitted to the ICU than children without neurologic disorders.

    The beneficial effect of macrolides for the treatment of community-acquired pneumonia (CAP) in combination with beta-lactams may be due to their anti-inflammatory activity. In patients with pneumococcal meningitis, the use of steroids improves outcomes only if they are administered before beta-lactams. The objective of this study was to compare outcomes in hospitalized patients with CAP when macrolides were administered before, simultaneously with, or after beta-lactams. Secondary data analysis of the Community-Acquired Pneumonia Organization (CAPO) International Cohort Study database. Study groups were defined based on the sequence of administration of macrolides and beta-lactams. The study outcomes were time to clinical stability (TCS), length of stay (LOS) and in-hospital mortality. Accelerated failure time models were used to evaluate the adjusted impact of sequential antibiotic administration and time-to-event outcomes, while a logistic regression model was used to evaluate their adjusted impact on mortality. A total of 99 patients were included in the macrolide before group and 305 in the macrolide after group. Administration of a macrolide before a beta-lactam compared to after a beta-lactam reduced TCS (3 vs. 4 days, p = .011), LOS (6 vs. 7 days, p = .002) and mortality (3 vs. 7.2%, p = .228). The administration of macrolides before beta-lactams was associated with a statistically significant decrease in TCS and LOS and a non-statistically significant decrease in mortality. The beneficial effect of macrolides in hospitalized patient with CAP may occur only if administered before beta-lactams.

    Microbiological profiles were analysed and compared for intra-abdominal, urinary, respiratory and bloodstream infections according to place of acquisition: community-acquired, with a separate analysis of healthcare-associated, and hospital-acquired. Prospective cohort study performed at a university tertiary care hospital over 1 year. Inclusion criteria were meeting the Centers for Disease Control definition of intra-abdominal, urinary, respiratory and bloodstream infections. A total of 1035 patients were included in the study. More than 25% of intra-abdominal infections were polymicrobial; multi-drug resistant gram-negatives were 38% in community-acquired, 50% in healthcare-associated and 57% in hospital-acquired. E. coli was the most prevalent among urinary infections: 69% in community-acquired, 56% in healthcare-associated and 26% in hospital-acquired; ESBL producers' pathogens were 10% in healthcare-associated and 3% in community-acquired and hospital-acquired. In respiratory infections Streptococcus pneumoniae was the most prevalent in community-acquired (54%) and MRSA in healthcare-associated (24%) and hospital-acquired (24%). A significant association was found between MRSA respiratory infection and hospitalization in the previous year (adjusted OR = 6.3), previous instrumentation (adjusted OR = 4.3) and previous antibiotic therapy (adjusted OR = 5.7); no cases were documented among patients without risk factors. Hospital mortality rate was 10% in community-acquired, 14% in healthcare-associated and 19% in hospital-acquired infection. This study shows that healthcare-associated has a different microbiologic profile than those from community or hospital acquired for the four main focus of infection. Knowledge of this fact is important because the existing guidelines for community-acquired are not entirely applicable for this group of patients.

    Prior retrospective studies suggest that statins may benefit patients with community-acquired pneumonia (CAP) due to antiinflammatory and immunomodulatory effects. However, prospective studies of the impact of statins on CAP outcomes are needed. We determined whether statin use was associated with improved outcomes in adults hospitalized with CAP. Adults aged ≥18 years hospitalized with CAP were prospectively enrolled at 3 hospitals in Chicago, Illinois, and 2 hospitals in Nashville, Tennessee, from January 2010-June 2012. Adults receiving statins before and throughout hospitalization (statin users) were compared with those who did not receive statins (nonusers). Proportional subdistribution hazards models were used to examine the association between statin use and hospital length of stay (LOS). In-hospital mortality was a secondary outcome. We also compared groups matched on propensity score. Of 2016 adults enrolled, 483 (24%) were statin users; 1533 (76%) were nonusers. Statin users were significantly older, had more comorbidities, had more years of education, and were more likely to have health insurance than nonusers. Multivariable regression demonstrated that statin users and nonusers had similar LOS (adjusted hazard ratio [HR], 0.99; 95% confidence interval [CI], .88-1.12), as did those in the propensity-matched groups (HR, 1.03; 95% CI, .88-1.21). No significant associations were found between statin use and LOS or in-hospital mortality, even when stratified by pneumonia severity. In a large prospective study of adults hospitalized with CAP, we found no evidence to suggest that statin use before and during hospitalization improved LOS or in-hospital mortality.

    Full Text Available Coxiella burnetii appears to be endemic in animals in the Mauricie region of Quebec, and causes some human cases of Q fever annually. Unlike in other rural areas, patients in this study experienced few respiratory symptoms. To determine whether C burnetii pneumonia is underdiagnosed, adults admitted to hospital for community acquired pneumonia were included in a one-year serological study. Significant immunofluorescent antibody (IFA titres in four of 118 patients with pneumonia (fewer than 4% were studied. Clinical presentation, standard laboratory tests and epidemiological data did not allow identification of these cases; however, Q fever increased during the warm months. There were no detectable complement fixing (CF antibodies in these four cases. C burnetii causes few cases of pneumonia in Mauricie. IFA seems to be a more sensitive test than CF.

    Kei Yamasaki

    Full Text Available BACKGROUND: Molecular biological modalities with better detection rates have been applied to identify the bacteria causing infectious diseases. Approximately 10-48% of bacterial pathogens causing community-acquired pneumonia are not identified using conventional cultivation methods. This study evaluated the bacteriological causes of community-acquired pneumonia using a cultivation-independent clone library analysis of the 16S ribosomal RNA gene of bronchoalveolar lavage specimens, and compared the results with those of conventional cultivation methods. METHODS: Patients with community-acquired pneumonia were enrolled based on their clinical and radiological findings. Bronchoalveolar lavage specimens were collected from pulmonary pathological lesions using bronchoscopy and evaluated by both a culture-independent molecular method and conventional cultivation methods. For the culture-independent molecular method, approximately 600 base pairs of 16S ribosomal RNA genes were amplified using polymerase chain reaction with universal primers, followed by the construction of clone libraries. The nucleotide sequences of 96 clones randomly chosen for each specimen were determined, and bacterial homology was searched. Conventional cultivation methods, including anaerobic cultures, were also performed using the same specimens. RESULTS: In addition to known common pathogens of community-acquired pneumonia [Streptococcus pneumoniae (18.8%, Haemophilus influenzae (18.8%, Mycoplasma pneumoniae (17.2%], molecular analysis of specimens from 64 patients with community-acquired pneumonia showed relatively higher rates of anaerobes (15.6% and oral bacteria (15.6% than previous reports. CONCLUSION: Our findings suggest that anaerobes and oral bacteria are more frequently detected in patients with community-acquired pneumonia than previously believed. It is possible that these bacteria may play more important roles in community-acquired pneumonia.

    Full Text Available Objective: The objective of this study was to identify the common etiological pathogens causing community acquired pneumonia (CAP in our hospital and sensitivity patterns to the common antibiotics used. Materials and Methods: This study was undertaken in a 750 bedded multi-specialty referral hospital in Kerala catering to both urban and semi-urban populations. It is a prospective study of patients who attended the medical out-patient department and those admitted with a clinical diagnosis of CAP, during the year 2009. Data were collected based on detailed patient interview, clinical examination and laboratory investigations. The latter included sputum culture and sensitivity pattern. These were tabulated and percentage incidence of etiological pathogens calculated. The antimicrobial sensitivity pattern was also classified by percentage and expressed as bar diagram. Results: The study showed Streptococcus pneumoniae to be the most common etiological agent for CAP, in our hospital setting. The other organisms isolated in order of frequency were Klebsiella pneumoniae, Pseudomonas aeruginosa, Alpha hemolytic streptococci, Escherichia coli, Beta hemolytic streptococci and atypical coli. S. pneumoniae was most sensitive to linezolid, followed by amoxicillin-clavulanate (augmentin, cloxacillin and ceftriaxone. Overall, the common pathogens causing CAP showed highest sensitivity to amikacin, followed by ofloxacin, gentamycin, amoxicillin-clavulanate (augmentin, ceftriaxone and linezolid. The least sensitivity rates were shown to amoxicillin and cefoperazone. Conclusion: In a hospital setting, empirical management for cases of CAP is not advisable. The present study has shown S. pneumoniae as the most likely pathogen and either linezolid or amikacin as the most likely effective antimicrobial in cases of CAP, in our setting.

    Full Text Available Pneumonia is a frequent cause of hospital admission in elderly patients. Diagnosis of pneumonia in elderly persons with comorbidity may be challenging, due to atypical presentation and complex clinical scenarios. Community-acquired pneumonia (CAP arises out-of-hospital in subjects without previous contact with the healthcare system. Healthcare associated pneumonia (HCAP occurs in patients who have frequent contacts with the healthcare system and should be treated with empiric broad spectrum antibiotic therapy also covering multi-drug resistant (MDR pathogens. Recent findings, however, have questioned this approach, because the worse prognosis of HCAP compared to CAP may better reflect increased level of comorbidity and frailty (poor functional status, older age of HCAP patients, as well as poorer quality of hospital care provided to such patients, rather than pneumonia etiology by MDR pathogens. The Pneumonia in Italian Acute Care for Elderly units (PIACE Study, promoted by the Società Italiana di Geriatria Ospedale e Territorio (SIGOT, is an observational prospective cohort study of patients consecutively admitted because of pneumonia to hospital acute care units of Geriatrics throughout Italy. Detailed information regarding clinical presentation, diagnosis, etiology, comprehensive geriatric assessment, antibiotic therapy, possible complications and comorbidities was recorded to identify factors potentially predicting in-hospital mortality (primary endpoint, 3-month mortality, length of hospital stay, postdischarge rate of institutionalization and other secondary endpoints. This paper describes the rationale and method of PIACE Study and reviews the main evidence on pneumonia in the elderly.

    2014-01-01

    Full Text Available Community-acquired pneumonia (CAP is a significant cause of morbidity and mortality, particularly in elderly patients, and is associated with a considerable economic burden on the healthcare system. The combination of high incidence and substantial financial costs necessitate accurate diagnosis and appropriate management of patients admitted with CAP. This article will discuss the rates of adherence to clinical guidelines, the use of severity scoring tools and the appropriateness of antimicrobial prescribing for patients diagnosed with CAP. The authors maintain that awareness of national and hospital guidelines is imperative to complement the physicians’ clinical judgment with evidence-based recommendations. Increased use of pneumonia severity assessment tools and greater adherence to therapeutic guidelines will enhance concordant antimicrobial prescribing for patients with CAP. A robust and multifaceted educational intervention, in combination with antimicrobial stewardship programs, may enhance compliance of CAP guidelines in clinical practice in Australia.

    Full Text Available Abstract Background The associations between socioeconomic status and community-acquired pneumonia outcomes in adults have been studied although studies did not always document a relationship. The aim of this multicenter observational study was to determine the association between socioeconomic status and community-acquired pneumonia outcomes in the elderly, in the context of a public health system providing universal free care to the whole population. Methods A total of 651 patients aged ≥65 years hospitalized due to community-acquired pneumonia through the emergency departments of five Spanish public hospitals were recruited and followed up between May 2005 and January 2007. The primary outcomes studied were: length of stay, intensive care unit admission, overall mortality and readmission. Socioeconomic status was measured using both individual and community data: occupation [categorized in six social groups (I, II, III, IVa, IVb and V], educational level (≤ primary level or ≥ secondary level and disposable family income of the municipality or district of residence [>12,500 € (high municipality family income and ≤12,500 € (low municipality family income]. The six social groups were further categorized as upper/middle social class (groups I-IVb and lower class (group V. Bivariate and multivariate analyses were performed. OR and their 95% confidence intervals were calculated. All statistical tests were two tailed and statistical significance was established as p Results 17.7% of patients lived in a municipality or district with a high municipality family income and 63.6% were upper/middle social class (I-IVb. Only 15.7% of patients had a secondary education. The adjusted analysis showed no association between pneumonia outcomes and social class, educational level or municipality family income. However, length of stay increased significantly in patients in whom the factors, living alone and being a smoker or ex-smoker coincided (p

    The initial antibiotic therapy of community-acquired pneumonia is carried out empirically. In the treatment of severe community-acquired pneumonia in children from 2 months to 5 years, the drug of choice is amoxicillin orally. Macrolides are the drugs of choice for children aged 5 to 16 years. In severe pneumonia, drugs of choice are amoxicillin clavulanate, 2nd–4th generation cephalosporins. In general, the duration of antibiotic therapy in the community-acquired pneumonia caused by typical bacteria is 7–10 days, by atypical bacteria — 10–14 days. In the real clinical practice, the errors associated with the choice of drug, route of administration, dosage, regimen of application, length of treatment are frequent during antibacterial therapy.

    Full Text Available BACKGROUND: Viruses are increasingly recognized as major causes of community-acquired pneumonia (CAP. Few studies have investigated the clinical predictors of viral pneumonia, and the results have been inconsistent. In this study, the clinical predictors of viral pneumonia were investigated in terms of their utility as indicators for viral pneumonia in patients with CAP. METHODS: Adult patients (≥ 18 years old with CAP, tested by polymerase chain reaction (PCR for respiratory virus, at two teaching hospitals between October 2010 and May 2013, were identified retrospectively. Demographic and clinical data were collected by reviewing the hospital electronic medical records. RESULTS: During the study period, 456 patients with CAP were identified who met the definition, and 327 (72% patients were tested using the respiratory virus PCR detection test. Viral pneumonia (n = 60 was associated with rhinorrhea, a higher lymphocyte fraction in the white blood cells, lower serum creatinine and ground-glass opacity (GGO in radiology results, compared to non-viral pneumonia (n = 250 (p < 0.05, each. In a multivariate analysis, rhinorrhea (Odd ratio (OR 3.52; 95% Confidence interval (CI, 1.58-7.87 and GGO (OR 4.68; 95% CI, 2.48-8.89 were revealed as independent risk factors for viral pneumonia in patients with CAP. The sensitivity, specificity, positive- and negative-predictive values (PPV and NPV of rhinorrhea were 22, 91, 36 and 83%: the sensitivity, specificity, PPV and NPV of GGO were and 43, 84, 40 and 86%, respectively. CONCLUSION: Symptom of rhinorrhea and GGO predicted viral pneumonia in patients with CAP. The high specificity of rhinorrhea and GGO suggested that these could be useful indicators for empirical antiviral therapy.

    Detection of the C-polysaccharide of Streptococcus pneumoniae in urine by an immune-chromatographic test is increasingly used to evaluate patients with community-acquired pneumonia. We assessed the sensitivity and specificity of this test in the largest series of cases to date and used logistic regression models to determine predictors of positivity in patients hospitalized with community-acquired pneumonia. We performed a multicenter, prospective, observational study of 4,374 patients hospitalized with community-acquired pneumonia. The urinary antigen test was done in 3,874 cases. Pneumococcal infection was diagnosed in 916 cases (21%); 653 (71%) of these cases were diagnosed exclusively by the urinary antigen test. Sensitivity and specificity were 60 and 99.7%, respectively. Predictors of urinary antigen positivity were female sex; heart rate≥125 bpm, systolic blood pressureantibiotic treatment; pleuritic chest pain; chills; pleural effusion; and blood urea nitrogen≥30 mg/dl. With at least six of all these predictors present, the probability of positivity was 52%. With only one factor present, the probability was only 12%. The urinary antigen test is a method with good sensitivity and excellent specificity in diagnosing pneumococcal pneumonia, and its use greatly increased the recognition of community-acquired pneumonia due to S. pneumoniae. With a specificity of 99.7%, this test could be used to direct simplified antibiotic therapy, thereby avoiding excess costs and risk for bacterial resistance that result from broad-spectrum antibiotics. We also identified predictors of positivity that could increase suspicion for pneumococcal infection or avoid the unnecessary use of this test.

    Full Text Available Abstract Background A variable decision in managing community acquired pneumonia (CAP is the initial site of care; in-patient versus outpatient. These variations persist despite comprehensive practice guidelines. Patients with a Pneumonia Severity Index (PSI score lower than seventy have low risk for complications and outpatient antibiotic management is recommended in this group. These patients are generally below the age of fifty years, non-nursing home residents, HIV negative and have no major cardiac, hepatic, renal or malignant diseases. Methods A retrospective analysis of 296 low-risk CAP patients evaluated within a year one period at St. Agnes Hospital, Baltimore, Maryland was undertaken.

    Knowing the most common microorganisms in our environment can help us to make proper empirical treatment decisions. The aim is to identify those microorganisms causing community-acquired pneumonia. An observational, descriptive and prospective study was conducted, including patients over 14 years with a clinical and radiographic diagnosis of community-acquired pneumonia during a 383 consecutive day period. A record was made of sociodemographic variables, personal history, prognostic severity scales, progress, and pathogenic agents. The aetiological diagnosis was made using blood cultures, detection of Streptococcus pneumoniae and Legionella pneumophila urinary antigens, sputum culture, influenza virus and Streptococcus pyogenes detection. Categorical variables are presented as absolute values and percentages, and continuous variables as their means and standard deviations. Of the 287 patients included in the study (42% women, mean age 66±22 years), 10.45% died and 70% required hospital admission. An aetiological diagnosis was achieved in 43 patients (14.98%), with 16 microorganisms found in 59 positive samples. The most frequently isolated pathogen was Streptococcus pneumonia (24/59, 41%), followed by gram-negative enteric bacilli, Klebsiella pneumonia, Escherichia coli, Serratia marcescens and Enterobacter cloacae isolated in 20% of the samples (12/59), influenza virus (5/59, 9%), methicillin-resistant Staphylococcus aureus (3/59, 5%), Pseudomonas aeruginosa (2/59, 3%), Moraxella catarrhalis (2/59, 3%), Legionella pneumophila (2/59, 3%), and Haemophilus influenza (2/59, 3%). Polymicrobial infections accounted for 14% (8/59). A high percentage of atypical microorganisms causing community-acquired pneumonia were found.

    The Community-Acquired Pneumonia Organization (CAPO) is an international observational study in 130 hospitals, with a total of 31 countries, to assess the current management of hospitalized patients with community-acquired pneumonia (CAP). 2 Using the centralized database of CAPO was decided to conduct this study with the aim of evaluate the level of adherence with national guidelines in Venezuela, to define in which areas an intervention may be necessary to improve the quality of care of hospitalized patients with CAP. In this observational retrospective study quality indicators were used to evaluate the management of hospitalized patients with CAP in 8 Venezuelan's centers. The care of the patients was evaluated in the areas of: hospitalization, oxygen therapy, empiric antibiotic therapy, switch therapy, etiological studies, blood cultures indication, and prevention. The compliance was rated as good (>90%), intermediate (60% to 90%), or low (Venezuela that are not performed according to the national guidelines of SOVETHORAX.1 In any quality improvement process the first step is to evaluate the difference between what is recommended and what is done in clinical practice. While this study meets this first step, the challenge for the future is to implement the processes necessary to improve the management of CAP in Venezuela. Copyright © 2013 SEPAR.

Aims: To investigate the role of C. pneumoniae in community-acquired lower respiratory tract infections (LRTIs in children using serological tests. Settings and Design: Two hundred children, age 2 months to 12 years, hospitalized for community-acquired LRTIs were investigated for C. pneumoniae etiology. Materials and Methods: We investigated 200 children hospitalized for community-acquired LRTIs, using ELISA for detecting anti-C. pneumoniae IgM and IgG antibodies. The demographic, clinical and radiological findings for C. pneumoniae antibody positive and C. pneumoniae antibody negative cases were compared. Statistical Analysis Used: Data analysis was performed by Chi-square test and Fisher′s exact tests using Epi Info (2002. Results: Clinical and radiological findings in both the groups were comparable. Serological evidence of C. pneumoniae infection was observed in 12 (6% patients; specific IgM antibodies were detected in 11 (91.67%; specific IgG antibodies in 1 (8.33% patients, while 4-fold rise in C. pneumoniae IgG antibody titers were noted in none of the patients. Conclusions: C. pneumoniae has a role in community-acquired LRTIs, even in children aged < 5 years. Serological detection using ELISA would enable pediatricians in better management of C. pneumoniae infections.

    Full Text Available Background: hospital-acquired pneumonia is a constant challenge given the current microbiological spectrum, antimicrobial resistance together with its high mortality, morbidity and hospital costs. Objective: to identify the clinical predictors of pneumonia associated with acute ischemic stroke. Methods: a prospective cohort study was conducted in 201 patients diagnosed with acute ischemic stroke consecutively admitted to the stroke unit of the General Carlos Manuel de Céspedes Teaching Hospital during the first seven days after the onset, from January 2012 through December 2013. The independent predictors of hospital-acquired pneumonia were obtained using multivariable logistic regression. Results: fifty six point seven percent were male. The mean age was 64.17 ± 14.33 years. Cases of hospital-acquired pneumonia associated with stroke accounted for 19, 9 %. Subjects who developed pneumonia were older (68.55 ± 13.51 vs. 63.08 ± 14.36 years, had a lower score in the Glasgow Coma Scale (8.00 ± 2.60 vs. 14.00 ± 2.82, and an increased number of leukocytes at admission (10.888 ± 3.487 vs. 9.233 ± 2.539 × 109/L. The following independent factors were identified: Glasgow Coma Scale ≤ 11 (OR: 26.099; 95 % CI 7.164-85.075, history of chronic obstructive pulmonary disease (OR: 8.896; 95 % CI 1.203-65.779, dysphagia (OR: 7.652; 95 % CI 2.369- 24.720, history of heart failure (OR: 4.583; 95 % CI 1.240- 16.932 and dysarthria/severe motor aphasia (OR: 4.222; 95 % CI 1.374- 12.975. Conclusions: the resulting logistic regression model is valid for predicting post-stroke pneumonia based on data routinely acquired.

    Our main objective was to assess the utility of the Pneumonia Severity Index (PSI) to decide the site of care home or hospital of patients with community-acquired pneumonia (CAP). All CAP patients who came to the emergency department from 1 January to 31 December, 2000, were prospectively assessed with a protocol based on the PSI and additional admission criteria applied to classes I, II and III. Mortality within 30 days and poor outcome were used as endpoints. We tested the diagnostic efficacy of the PSI scale in predicting mortality or unfavourable events by calculating the area below the ROC curve. Of the 243 CAP patients included, 124 (51%) belonged to classes I, II and III, and 119 (49%) belonged to classes IV and V. One hundred and fifty six (64%) patients were admitted. Fifteen (6.2%) patients died, all of them belonging to classes IV and V. Forty four (18%) patients showed a poor outcome. Only one patient who was initially sent home had a poor outcome. The prognostic value of the PSI scale to predict mortality (ROC = 0.92; CI 95%, 0.88-0.95) was high. Our results confirm that the PSI scale is a good prognostic index in clinical practice for predicting mortality due to CAP. In order to use the PSI to decide the site of care of patients with CAP, not only the score obtained but also additional factors should be taken into account.

    Eighty-five isolates of Klebsiella pneumoniae and Enterobacter spp., originating from hospital- and community-acquired infections and from oropharyngeal and faecal microbiota from patients in Recife-PE, Brazil, were analyzed regarding the presence of irp2 gene. This is a Yersinia typical gene involved in the synthesis of siderophore yersiniabactin. DNA sequencing confirmed the identity of irp2 gene in five K. pneumoniae, five Enterobacter aerogenes and one Enterobacter amnigenus isolates. To our knowledge in the current literature, this is the first report of the irp2 gene in E. amnigenus, a species considered an unusual human pathogen, and in K. pneumoniae and E. aerogenes isolates from the normal microbiota and from community infections, respectively. Additionally, the analyses of nucleotide and amino acid sequences suggest the irp2 genes derived from isolates used in this study are more closely related to that of Yersinia pestis P.CE882 than to that of Yersinia enterocolitica 8081. These data demonstrated that K. pneumoniae and Enterobacter spp. from normal microbiota and from community- and hospital-acquired infections possess virulence factors important for the establishment of extra-intestinal infections.

    Objective: To compare the clinical response to amoxicillin, cefuroxime and clarithromycin in the treatment of community-acquired pneumonia in children and to see the cost effectiveness of each treatment. Subjects and Methods: Patients between 3 to 72 months of age, admitted in the hospital with community acquired pneumonia, were randomly divided into three groups 1,2,3. They were started on amoxicillin, cefuroxime and clarithromycin respectively. The patients were assessed daily. If there was no clinical improvements at 48 hours the antibiotic was changed. ANOVA statistical test was applied to see the clinical response to the treatment in the three groups. Cost effectiveness of the treatment was compared. Results: There was no statistical difference in the clinical response at 48 hours of initiating treatment and discharge (p>0.01 each). The mean hospital stay in group 1 and 2 was 3.3 days and group 3 was 3.2 days respectively (p>0.01). Ninety-seven percent patients in group 1 and 3, and 95% patients in group 2 showed clinical improvement. The cost of treatment of community acquired pneumonia for 8 days was Rs. 496/-, 730/-, 1018/- for amoxicillin, clarithromycin and cefuroxime respectively. Conclusion: Amoxicillin was found in the most cost effective followed by clarithromycin and cefuroxime respectively in the treatment of non-severe and severe community-acquired pneumonia. (author)

    Pneumonia is a major cause of mortality in children. The objective of this study was to construct a prognostic scale for estimation of mortality applicable to children with community-acquired pneumonia (CAP). This observational study included patients younger than 15 years with a diagnosis of CAP who were hospitalized between 2004 and 2013. A point-based scoring system based on the modification of the PIRO scale used in adults with pneumonia was applied to each child hospitalized with CAP. It included the following variables: predisposition (age pneumonia) and organ dysfunction (kidney failure, liver failure and acute respiratory distress syndrome). One point was given for each feature that was present (range, 0-10 points). The association between the modified PIRO score and mortality was assessed by stratifying patients into 4 levels of risk: low (0-2 points), moderate (3-4 points), high (5-6 points) and very high risk (7-10 points). Eight hundred sixty children hospitalized with CAP were eligible for study. The mean age was 2.8 ± 3.2 years. The observed mortality was 6.5% (56/860). Mortality ranged from 0% for a low PIRO score (0/708 pts), 18% (20/112 pts) for a moderate score, 83% (25/30 pts) for a high score and 100% (10/10 pts) for a very high modified PIRO score (P < 0.001). The present score accurately discriminated the probability of death in children hospitalized with CAP, and it could be a useful tool to select candidates for admission to intensive care unit and for adjunctive therapy in clinical trials.

    Full Text Available Objective: To evaluate the clinical, laboratory, radiological, and demographic data of H3N2 pneumonia cases hospitalized to the Pulmonology Department during H3N2 pandemics and compare them with non-H3N2 community-acquired pneumonia (CAP cases. Methods: The study population consisted of all CAP cases hospitalized to our Pulmonology Department between December 2013 and February 2014 during the influenza outbreak. The patient files were evaluated for physical findings, laboratory data, radiological findings, and treatment and outcome of cases. H3N2 was diagnosed using polymerase chain reaction (PCR analysis of throat swabs. The clinical, radiological, and laboratory findings of H3N2 pneumonia cases were compared with those of non-H3N2 pneumonia cases. Mann–Whitney U test, Chi-square test, Fisher’s exact test, and logistic regression analysis by the forward step wise method were used for statistical analyses. P value0.05. The rates of treatment failure and/or transport to the intensive care unit with the need of invasive mechanical ventilation and mortality rates were also similar in both groups (p>0.05. Conclusion: H3N2 pneumonia/viral pneumonia is a member of CAP. Although the number of H3N2 cases are extremely small to draw a conclusion, the results of this study highlight that the clinical, radiological, and laboratory findings of H3N2 pneumonia cases are not different from those of non-H3N2 CAP cases.

    The diagnosis of community-acquired pneumonia (CAP) is often not possible based only on the clinical symptoms and biochemical parameters. For every patient with the suspicion of CAP, a chest radiograph in two planes should be carried out. Additionally, a risk stratification for the decision between outpatient therapy or hospitalization is recommended. Based on the evaluation of the different radiological patterns as well as their extent and distribution, a rough allocation to so-called pathogen groups as well as a differentiation between viral and bacterial infections are possible; however, because different pathogens cause different patterns an accurate correlation is not feasible by relying purely on imaging. The radiological findings serve as proof or exclusion of pneumonia and can also be used to evaluate the extent of the disease (e.g. monolobular, multilobular, unilateral or bilateral). In cases of prolonged disease, suspicion of complications (e.g. pleural effusion or empyema, necrotizing pneumonia or abscess) or comorbid conditions (e.g. underlying pulmonary or mediastinal diseases) computed tomography is an important diagnostic tool in addition to chest radiography. Ultrasound is often used to diagnose pleural processes (e.g. parapneumonic effusion or pleural empyema). (orig.) [German] Anhand der klinischen Symptome und laborchemischen Befundkonstellation alleine ist es oft nicht moeglich, die Diagnose einer ambulant erworbenen Pneumonie (''community-acquired pneumonia'', CAP) zu stellen.

    Pneumonia remains one of the major disease entities practicing physicians must manage. It is a leading cause of infection-related morbidity and mortality in all age groups, and a leading cause of death in those older than 65 years of age. Despite its frequency and importance, clinical questions have remained in the therapy of community-acquired pneumonia including when to start antibiotics, when to stop them, who to treat, and what agents to use. Answers to these questions have involved historical practice, mythology, and science-sometimes good science, and sometimes better science. How clinical decisions are made for patients with community-acquired pneumonia serves as an illustrative model for other problem areas of medicine and allows for insight as to how clinical decisions have been made and clinical practice established.

    This review focuses on the evidence base for guideline recommendations on the diagnosis, the optimal choice, timing and duration of empirical antibiotic therapy, and the use of microbiological tests for patients hospitalized with community-acquired pneumonia (CAP): issues for which guidelines are frequently used as a quick reference. Furthermore, we will discuss possibilities for future research in these topics. Many national and international guideline recommendations, even on critical elements of CAP management, are based on low-to-moderate quality evidence. The diagnosis and management of CAP has hardly changed for decades. The recommendation to cover atypical pathogens in all hospitalized CAP patients is based on observational studies only and is challenged by two recent trials. The following years, improved diagnostic testing, radiologically by low-dose Computed Tomography or ultrasound and/or microbiologically by point-of-care multiplex PCR, has the potential to largely influence the choice and start of antibiotic therapy in hospitalized CAP patients. Rapid microbiological testing will hopefully improve antibiotic de-escalation or early pathogen-directed therapy, both potent ways of reducing broad-spectrum antibiotic use. Current guideline recommendations on the timing and duration of antibiotic therapy are based on limited evidence, but will be hard to improve.

    The aim of the work was to evaluate the efficiency of microbial probiotics Vitaflor and metabolic probiotic Aktoflor-C in complex treatment of community-acquired pneumonia in adolescents in a hospital. The observation involved 38 children aged 11 to 18 years with radiologically verified community-acquired pneumonia, including 23 boys and 15 girls. Patients were divided in 3 groups. Patients in group 1 (n = 13) simultaneously with the antibiotic therapy received per os Vitaflor probiotic containing symbiotic strains of Lactobacillus acidophilus; patients in group 2 (n = 10) along with antibiotic therapy received per os metabolic probiotic Aktoflor-C, containing low molecular weight exometabolites bacteria; patient of the comparison group (n = 15) received antibiotic therapy only. The effectiveness of the used treatment schemes was assessed on the dynamics of the gut state microbiot acoarding to an extended bacteriological examination of faecal flora, level of saliva IgA secretory (before and after treatment), the dynamics of SF-36 quality of life 1 month after discharge from hospital. Was conducted a study of economic efficiency of different modes of therapy. Results showed that adolescents with community-acquired pneumonia during standard antibiotic therapy indicated development of dysbiotic bowel disturbances in the form of reliable oppression of the bifidobacteria and laktoflora. Dysbiosis of the microbial associations are not conducive to proper implementation of immune and nutritional functions of the intestine that shows the imperfection of rehabilitation of patients with pneumonia according to the evaluation of SF-36 quality of life. Pharmacoeconomic analysis revealed the benefits of probiotic metabolic type "Aktoflor" used in addition to standard therapy of community-acquired pneumonia in adolescents.

    To evaluate the usefulness of sputum gram staining in community-acquired pneumonia (CAP), we reviewed 144 cases requiring hospitalization in the last 4 years. The sensitivity was 75.5%, specificity 68.2%, positive predictive value 74.1%, negative predictive value 69.8%, positive likelihood ratio 2.37, negative likelihood ratio 0.36 and accuracy 72.2% in 97 cases. Both sputum gram staining and culture were performed. Concerning bacterial pneumonia (65 cases), we compared the Gram staining group (n = 33), which received initial antibiotic treatment, based on sputum gram staining with the Empiric group (n = 32) that received antibiotics empirically. The success rates of the initial antibiotic treatment were 87.9% vs. 78.1% (P = 0.473); mean hospitalization periods were 9.67 vs. 11.75 days (P = 0.053); and periods of intravenous therapy were 6.73 vs. 7.91 days (P = 0.044), respectively. As for initial treatment, penicillins were used in the Gram staining group more frequently (P gram staining is useful for the shortening of the treatment period and the appropriate selection of initial antibiotics in bacterial pneumonia. We believe, therefore, that sputum gram staining is indispensable as a diagnostic tool CAP.

    Extracorporeal membrane oxygenation is a rescue therapy used to support severe cardiorespiratory failure. Data on outcomes from severe community-acquired pneumonia in adults receiving rescue extracorporeal membrane oxygenation are mainly confined to single-center experiences or specific pathogens. We examined data from the Extracorporeal Life Support Organisation registry to identify risk factors for poor outcomes in adult patients with community-acquired pneumonia. Retrospective data analysis. Extracorporeal Life Support Organization Registry database. We collected deidentified data on adult patients (> 18 yr) receiving extracorporeal membrane oxygenation for community-acquired pneumonia between 2002 and 2012. Patients with incomplete data or brain death were excluded. The primary outcome measure was in-hospital mortality. Other measurements included demographic information, pre-extracorporeal membrane oxygenation mechanical ventilation and biochemical variables, inotrope requirements, extracorporeal membrane oxygenation mode, duration, and complications. Initial univariate analysis assessed potential associations between survival and various pre-extracorporeal membrane oxygenation and extracorporeal membrane oxygenation factors. Variables with p values of less than 0.1 were considered for logistic regression analysis to identify predictors of mortality. None. One thousand fifty-five patients, who satisfied inclusion criteria, were included in the final analysis. There was an increase in the number of patients cannulated per annum over the 10-year period studied. Univariate analysis identified pre-extracorporeal membrane oxygenation and extracorporeal membrane oxygenation variables associated with high mortality. Further multiple regression analysis identified certain pre-extracorporeal membrane oxygenation factors as predictors of mortality, including duration of mechanical ventilation prior to extracorporeal membrane oxygenation, lower arterial pressure, fungal

    Pneumonia continues to be a leading cause of hospitalization and mortality. Implementation of health information technology (HIT) can lead to cost savings and improved care. In this review, we examine the literature on the use of HIT in the management of community-acquired pneumonia. We also discuss barriers to adoption of technology in managing pneumonia, the reliability and quality of electronic health data in pneumonia research, how technology has assisted pneumonia diagnosis and outcomes research. The goal of using HIT is to develop and deploy generalizable, real-time, computerized clinical decision support integrated into usual pneumonia care.

    Introduction: Severe community acquired pneumonia (SCAP) occurs in approximately 18–36% of all CAP and the mortality rate could be as high as 67% in patients with SCAP. Several studies have described a correlation between baseline lactate concentration and mortality of ICU patients. Aim of the work: To follow lactate clearance after admission for 24 h which could be an indicator of outcome in severe community acquired pneumonia. Patients and methods: Forty-six consecutively admitted adu...

    Ultrasound (US) has been proposed as an alternative first-line imaging modality to diagnose community-acquired pneumonia in children. Lung US has the potential benefits over chest radiography of being radiation free, subject to fewer regulatory requirements, relatively lower cost and with immediate bedside availability of results. However, the uptake of lung US into clinical practice has been slow and it is not yet included in clinical guidelines for community-acquired pneumonia in children. The aim of this review is to give an overview of the equipment and techniques used to perform lung US in children with suspected pneumonia and the interpretation of relevant sonographic findings. We also summarise the current evidence of diagnostic accuracy and reliability of lung US compared to alternative imaging modalities in children and critically consider the strengths and limitations of lung US for use in children presenting with suspected community-acquired pneumonia.

    Full Text Available Aim of the study — to examine the effectiveness of sequential therapy of injectable and oral forms cephalosporins of II generation, cefuroxime sodium and cefprozil, in children with acute community-acquired pneumonia. We examined 53 child patients aged 6 months — 14 years with acute community-acquired pneumonia. Patients were divided into 2 groups: 1st group — 26 patients who treated with cefuroxime sodium intramuscularly, and 2nd — 27 patients who treated with cefuroxime sodium in first 3 days and then from the 4th day — with cefprozil suspension orally. Both groups of patients were comparable by forms and course of pneumonia. In the clinic to all patients were conducted conventional clinical and laboratory investigations. Complex therapy was not different in both groups. Efficacy of treatment was assessed in dynamics. When comparing the effectiveness of two antibiotic regimens (cefuroxime sodium parenterally and sequential regimen with replacement by cefprozil orally there were no differences in the dynamics of clinical course, laboratory and radiological data. Finding of the conducted investigations before treatment showed that majority of patients had clinical and radiological evidence of pneumonia: fever, cough, shortness of breath, tachycardia, physical and radiological changes in the lungs. Evaluation of treatment efficacy showed that by the end of treatment in both groups of patients there was a positive clinical and radiological dynamics of the disease, the body temperature returned to normal, symptoms of intoxication, physical changes in the lungs disappeared, focal and infiltrative changes disappeared completely. Thus, sequential therapy with cephalosporins of II generation, cefuroxime and cefprozil, in the treatment of acute community-acquired pneumonia in children is a quite effective and safe method with good tolerability and no side effects.

    Androgens have been shown to influence both the immune system and lung tissue, raising the hypothesis that androgen deprivation therapy (ADT) for prostate cancer may increase the risk of pneumonia. Thus, the aim of this study was to determine whether ADT is associated with an increased risk of hospitalisation for community-acquired pneumonia in patients with prostate cancer. This was a population-based cohort study using the United Kingdom Clinical Practice Research Datalink linked to the Hospital Episode Statistics repository. The cohort consisted of 20 310 men newly diagnosed with non-metastatic prostate cancer between 1 April 1998 and 31 March 2015. Time-dependent Cox proportional hazards models were used to estimate adjusted HRs and 95% CIs for hospitalisation for community-acquired pneumonia associated with current and past use of ADT compared with non-use. During a mean follow-up of 4.3 years, there were 621 incident hospitalisations for community-acquired pneumonia (incidence rate: 7.2/1000 person-years). Current ADT use was associated with an 81% increased risk of hospitalisation for community-acquired pneumonia (12.1 vs 3.8 per 1000 person-years, respectively; HR 1.81, 95% CI 1.47 to 2.23). The association was observed within the first six months of use (HR 1.73, 95% CI 1.23 to 2.42) and remained elevated with increasing durations of use (≥25 months; HR 1.79, 95% CI 1.39 to 2.30). In contrast, past ADT use was not associated with an increased risk (HR 1.23, 95% CI 0.95 to 1.60). The use of ADT is associated with an increased risk of hospitalisation for community-acquired pneumonia in men with prostate cancer. Published by the BMJ Publishing Group Limited.

    Rita de Cássia Coelho Moraes de Brito

    Full Text Available Abstract Objectives: to describe the clinical characteristics and outcomes of acute community acquired pneumonia in children at a reference public hospital in Pernambuco State, Brazil (2010-2011 Methods: pneumonia case series of 80 children aged 28 days to 14 years old at Hospital da Restauração in Pernambuco, Brazil, from 2010 to 2011. Information was noted from medical files, and two comparison groups were created according to the severity of the disease, considering the presence of pleural effusion. Fisher or Mann-Whitney tests were used for comparative analyses. Results: severe pneumonia with pleural effusion was more frequent in children under five years of age (p=0,025, and was associated with longer period of fever (19 x 15 days and coughing (17 x 13 days, when compared to non-complicated pneumonia cases. Six children (7,5%, 6/80 died, 50% before the fourth day of hospitalization (p=0,001. All deaths were from the pleural effusion group in children from the countryside (p=0,026. Conclusions: the severity of pneumonia in children attended at this hospital is related to younger children, and those transferred from the health units in the countryside, so, early diagnosis and medical intervention are limited by infrastructure and available resources for the health.

    Cupriavidus pauculus is a gram-negative, aerobic, non-spore forming, non-fermentative motile bacillus. The bacillus can be isolated from water, bottled mineral water, and water from ultrafiltration systems in hospital setting. C. pauculus rarely causes human infections, however it may be an infectious agent especially in immunocompromised individuals. In this report, we present the first case of community acquired pneumonia caused by C. pauculus in a previously healthy newborn who was hospitalized in neonatal intensive care unit on postnatal day 16 because of respiratory distress.

    The credibility of prognostic indicators in nursing-home-acquired pneumonia (NHAP) is not clear. We previously reported a simple prognostic indicator in community-acquired pneumonia (CAP): blood urea nitrogen to serum albumin (B/A) ratio. This retrospective study investigated the prognostic value of severity indicators in NHAP versus CAP in elderly patients. Patients aged ≥65 years and hospitalized because of NHAP or CAP within the previous 3 years were enrolled. Demographics, coexisting illnesses, laboratory and microbiological findings, and severity scores (confusion, urea, respiratory rate, blood pressure, and age ≥65 [CURB-65] scale; age, dehydration, respiratory failure, orientation disturbance, and pressure [A-DROP] scale; and pneumonia severity index [PSI]) were retrieved from medical records. The primary outcome was mortality within 28 days of admission. In total, 138 NHAP and 307 CAP patients were enrolled. Mortality was higher in NHAP (18.1%) than in CAP (4.6%) (Pscale, 0.69 for the CURB-65 scale, 0.67 for the PSI class, and 0.65 for the B/A ratio. The area under the curve in CAP was 0.73 for the A-DROP scale, 0.76 for the CURB-65 scale, 0.81 for the PSI class, and 0.83 for the B/A ratio. Patient mortality was greater in NHAP than in CAP. Patient characteristics, coexisting illnesses, and detected pathogens differed greatly between NHAP and CAP. The existing severity indicators had less prognostic value for NHAP than for CAP.

  18. Community-acquired pneumonia among smokers.

    Recent studies have left absolutely no doubt that tobacco increases susceptibility to bacterial lung infection, even in passive smokers. This relationship also shows a dose-response effect, since the risk reduces spectacularly 10 years after giving up smoking, returning to the level of non-smokers. Streptococcus pneumoniae is the causative microorganism responsible for community-acquired pneumonia (CAP) most frequently associated with smoking, particularly in invasive pneumococcal disease and septic shock. It is not clear how it acts on the progress of pneumonia, but there is evidence to suggest that the prognosis for pneumococcal pneumonia is worse. In CAP caused by Legionella pneumophila, it has also been observed that smoking is the most important risk factor, with the risk rising 121% for each pack of cigarettes smoked a day. Tobacco use may also favor diseases that are also known risk factors for CAP, such as periodontal disease and upper respiratory viral infections. By way of prevention, while giving up smoking should always be proposed, the use of the pneumococcal vaccine is also recommended, regardless of the presence of other comorbidities.

    To present lung ultrasound findings in children assessed with suspected pneumonia in the emergency department and to show the benefit of lung ultrasound in diagnosing pneumonia in comparison with chest X-rays. This observational prospective study was performed in the pediatric emergency department of a single center. Point of care lung ultrasound was performed on each child by an independent sonographer blinded to the patient's clinical and chest X-ray findings. Community acquired pneumonia was established as a final diagnosis by two clinicians based on the recommendations in the British Thoracic Society guideline. One hundred sixty children with a mean age of 3.3±4years and a median age of 1.4years (min-max 0.08-17.5years) were investigated. Final diagnosis in 149 children was community-acquired pneumonia. Lung ultrasound findings were compatible with pneumonia in 142 (95.3%) of these 149 children, while chest X-ray findings were compatible with pneumonia in 132 (88.5%). Pneumonia was confirmed with lung ultrasound in 15 of the 17 patients (11.4%) not evaluated as compatible with pneumonia at chest X-ray. While pneumonia could not be confirmed with lung ultrasound in seven (4.6%) patients, findings compatible with pneumonia were not determined at chest X-ray in two of these patients. When lung ultrasound and chest X-ray were compared as diagnostic tools, a significant difference was observed between them (p=0.041). This study shows that lung ultrasound is at least as useful as chest X-ray in diagnosing children with community-acquired pneumonia. Copyright © 2017 Elsevier Inc. All rights reserved.

    Abstract Objective To determine the attributable risk of community acquired pneumonia on incidence of heart failure throughout the age range of affected patients and severity of the infection. Design Cohort study. Setting Six hospitals and seven emergency departments in Edmonton, Alberta, Canada, 2000-02. Participants 4988 adults with community acquired pneumonia and no history of heart failure were prospectively recruited and matched on age, sex, and setting of treatment (inpatient or outpatient) with up to five adults without pneumonia (controls) or prevalent heart failure (n=23 060). Main outcome measures Risk of hospital admission for incident heart failure or a combined endpoint of heart failure or death up to 2012, evaluated using multivariable Cox proportional hazards analyses. Results The average age of participants was 55 years, 2649 (53.1%) were men, and 63.4% were managed as outpatients. Over a median of 9.9 years (interquartile range 5.9-10.6), 11.9% (n=592) of patients with pneumonia had incident heart failure compared with 7.4% (n=1712) of controls (adjusted hazard ratio 1.61, 95% confidence interval 1.44 to 1.81). Patients with pneumonia aged 65 or less had the lowest absolute increase (but greatest relative risk) of heart failure compared with controls (4.8% v 2.2%; adjusted hazard ratio 1.98, 95% confidence interval 1.5 to 2.53), whereas patients with pneumonia aged more than 65 years had the highest absolute increase (but lowest relative risk) of heart failure (24.8% v 18.9%; adjusted hazard ratio 1.55, 1.36 to 1.77). Results were consistent in the short term (90 days) and intermediate term (one year) and whether patients were treated in hospital or as outpatients. Conclusion Our results show that community acquired pneumonia substantially increases the risk of heart failure across the age and severity range of cases. This should be considered when formulating post-discharge care plans and preventive strategies, and assessing downstream episodes

    Full Text Available Abstract Background Some forms of pharmacotherapy are shown to increase the risk of community-acquired pneumonia (CAP. The purpose of this study is to investigate whether pharmacotherapy with proton pump inhibitors (PPI, inhaled corticosteroids, and atypical antipsychotics was associated with the increased risk for CAP in hospitalized older adults with the adjustment of known risk factors (such as smoking status and serum albumin levels. Methods A retrospective case-control study of adults aged 65 years or older at a rural community hospital during 2004 and 2006 was conducted. Cases (N = 194 were those with radiographic evidence of pneumonia on admission. The controls were patients without the discharge diagnosis of pneumonia or acute exacerbation of chronic obstructive pulmonary disease (COPD (N = 952. Patients with gastric tube feeding, ventilator support, requiring hemodialysis, metastatic diseases or active lung cancers were excluded. Results Multiple logistic regression analysis revealed that the current use of inhaled corticosteroids (adjusted odds ratio [AOR] = 2.89, 95% confidence interval [CI] = 1.56-5.35 and atypical antipsychotics (AOR = 2.26, 95% CI = 1.23-4.15 was an independent risk factor for CAP after adjusting for confounders, including age, serum albumin levels, sex, smoking status, a history of congestive heart failure, coronary artery disease, and COPD, the current use of PPI, β2 agonist and anticholinergic bronchodilators, antibiotic(s, iron supplement, narcotics, and non-steroidal anti-inflammatory drugs. The crude OR and the AOR of PPI use for CAP was 1.41 [95% CI = 1.03 - 1.93] and 1.18 [95% CI = 0.80 - 1.74] after adjusting for the above confounders, respectively. Lower serum albumin levels independently increased the risk of CAP 1.89- fold by decreasing a gram per deciliter (AOR = 2.89, 95% CI = 2.01 - 4.16.

    The Sepsis-3 Task Force updated the clinical criteria for sepsis, excluding the need for systemic inflammatory response syndrome (SIRS) criteria. The clinical implications of the proposed flowchart including the quick Sequential (Sepsis-related) Organ Failure Assessment (qSOFA) and SOFA scores are unknown. To perform a clinical decision-making analysis of Sepsis-3 in patients with community-acquired pneumonia. This was a cohort study including adult patients with community-acquired pneumonia from two Spanish university hospitals. SIRS, qSOFA, the Confusion, Respiratory Rate and Blood Pressure (CRB) score, modified SOFA (mSOFA), the Confusion, Urea, Respiratory Rate, Blood Pressure and Age (CURB-65) score, and Pneumonia Severity Index (PSI) were calculated with data from the emergency department. We used decision-curve analysis to evaluate the clinical usefulness of each score and the primary outcome was in-hospital mortality. Of 6,874 patients, 442 (6.4%) died in-hospital. SIRS presented the worst discrimination, followed by qSOFA, CRB, mSOFA, CURB-65, and PSI. Overall, overestimation of in-hospital mortality and miscalibration was more evident for qSOFA and mSOFA. SIRS had lower net benefit than qSOFA and CRB, significantly increasing the risk of over-treatment and being comparable with the "treat-all" strategy. PSI had higher net benefit than mSOFA and CURB-65 for mortality, whereas mSOFA seemed more applicable when considering mortality/intensive care unit admission. Sepsis-3 flowchart resulted in better identification of patients at high risk of mortality. qSOFA and CRB outperformed SIRS and presented better clinical usefulness as prompt tools for patients with community-acquired pneumonia in the emergency department. Among the tools for a comprehensive patient assessment, PSI had the best decision-aid tool profile.

    The prognostic significance of platelet count (PC) changes during hospitalization for community-acquired pneumonia (CAP) has not been investigated. For 976 adults, clinical data during hospitalization for CAP and all-cause mortality following discharge were compared according to ΔPC (PC on discharge minus PC on admission): groups A (declining PC, ΔPC 50 × 10 9 /l), and according to the presence of thrombocytopenia, normal PC, and thrombocytosis on admission/discharge. Groups A, B, and C comprised 7.9%, 46.5%, and 45.6% of patients, respectively. On hospital admission/discharge, thrombocytopenia, normal PC, and thrombocytosis were observed in 12.8%/6.4%, 84.1%/84.4%, and 3.1%/9.2% of patients, respectively. The respective 90-day, 3-year, and total (median follow-up of 54 months) mortality rates were significantly higher: in group A (40.3%, 63.6%, and 72.7%), compared to groups B (12.3%, 31.5%, and 39.0%) and C (4.9%, 17.3%, and 25.4%), p < 0.001; and in patients with thrombocytopenia at discharge (27.4%, 48.4%, and 51.6%), compared to those with normal PC (10.2%, 26.9%, and 35.4%) and thrombocytosis (8.9%, 17.8%, and 24.4%) at discharge (p < 0.001). Mortality rates were comparable among groups with thrombocytopenia, normal PC, and thrombocytosis at admission (p = 0.6). In the entire sample, each 100 × 10 9 /l increment of ΔPC strongly predicted lower mortality (p < 0.001, relative risk 0.73, 95% confidence interval 0.64-0.83). In conclusion, PC changes are common among CAP inpatients. Rising PC throughout hospitalization is a powerful predictor of better survival, while declining PC predicts poor outcome. Evaluation of PC changes during hospitalization for CAP may provide useful prognostic information.

    Data on hospitalization burden of CAP in children is very limited in China. This study aimed to estimate the hospitalization rate and population-based incidence of hospitalization of CAP for children <15 years of age in Suzhou, China. This was a retrospective study of children hospitalized in Soochow University Affiliated Children's Hospital (SCH) from January 2010 to December 2014. Children who were residents of downtown Suzhou, 29 days to <15 years of age, with discharge diagnosis codes (ICD-10) including J09 to J18 and J20 to J22 were included. All-cause clinical community-acquired pneumonia (CCAP) and radiographically confirmed pneumonia (RCAP) were identified based on individual medical chart review. The hospitalization rate (HR) and population-based cumulative incidence of hospitalization (HI) were calculated. Among 184,734 children <15 years old admitted to SCH during the study period, 31,302 children were identified as having CCAP, and 24,218 (77.4%) children confirmed as having RCAP. CCAP hospitalization occurred year round and peaked during winter and early spring. The overall HRs for CCAP and RCAP were 189.0 (95%CI, 187.1-190.9) and 146.2 (95%CI, 144-148) per 1,000 hospitalizations respectively, and the HIs per 100,000 children annually were CCAP, 3,235.8 (95%CI, 3207.3-3264.2) and RCAP, 2,503.5 (95%CI, 2,478.3-2,528.6). For children <5 years old, the HR for CCAP was 248.4 (95%CI, 245.9-250.9) and RCAP 194.0 (95%CI, 191.4-196.3) per 1,000 hospitalizations; the HI for CCAP was 6,956.2 (95%CI: 6,892.8-7,019.6) and 5,431.9 (95%CI: 5,375.4-5,488.4) per 100,000 children for RCAP. The highest HR and HI were observed in children 29 days to <6 months old: HR for CCAP was 407.4 (95%CI: 400.9-413.9) per 1,000 hospitalizations and HI for CCAP was 11,203.7 (95%CI: 11,026.8-11,380.6) per 100,000 children annually. There is a considerable burden of CAP among children <15 years of age in Suzhou, particularly among children 29 days to <6 months of age and during winter

    Recent Food and Drug Administration (FDA) guidance endorses the use of an early clinical response endpoint as the primary outcome for community-acquired bacterial pneumonia (CABP) trials. While antibiotics will now be approved for CABP, in practice they will primarily be used to treat patients with community-acquired pneumonia (CAP). More importantly, it is unclear how achievement of the new FDA CABP early response endpoint translates into clinically applicable real-world outcomes for patients with CAP. To address this, a retrospective cohort study was conducted among adult patients who received ceftriaxone and azithromycin for CAP of Pneumonia Outcomes Research Team (PORT) risk class III and IV at an academic medical center. The clinical response was defined as clinical stability for 24 h with improvement in at least one pneumonia symptom and with no symptom worsening. A classification and regression tree (CART) was used to determine the delay in response time, measured in days, associated with the greatest risk of a prolonged hospital length of stay (LOS) and adverse outcomes (in-hospital mortality or 30-day CAP-related readmission). A total of 250 patients were included. On average, patients were discharged 2 days following the achievement of a clinical response. In the CART analysis, adverse clinical outcomes were higher among day 5 nonresponders than those who responded by day 5 (22.4% versus 6.9%, P = 0.001). The findings from this study indicate that time to clinical response, as defined by the recent FDA guidance, is a reasonable prognostic indicator of real-world effectiveness outcomes among hospitalized PORT risk class III and IV patients with CAP who received ceftriaxone and azithromycin.

    Legionella pneumophila is the causal agent of 5% to 12% of sporadic community-acquired pneumonia cases, though rates are changing with the use of new diagnostic methods. This is a retrospective study of all patients admitted to our hospital with community-acquired pneumonia due to Legionella pneumophila between 1997 and 2001. Diagnostic criteria included either a positive Legionella serogroup 1 urinary antigen test or seroconversion and a chest radiograph consistent with pneumonia. A total of 97 patients were studied. Ninety cases (92.8%) were community-acquired and 7 (7.2%) were associated with travelling. In 82 cases (84.5%) the presentation was sporadic. Seventy-five patients were smokers (77.3%). The most common symptoms were fever in 91 patients (93.8%) and cough in 67 (68.1%). In five patients (5.2%) creatine phosphokinase concentrations were over 5 times their baseline values (in two over 100 times); four of these patients presented acute renal failure. Seroconversion was observed in 23/42 patients (54.8%). There were no statistically significant differences between the administration of erythromycin or clarithromycin in monotherapy, or in combination with rifampin. Nineteen patients (19.6%) presented acute renal failure and mechanical ventilation was necessary in 22 (22.7%). Twelve patients died (12.5%). Independent prognostic factors associated with death included respiratory rate > 30 breaths/min, urea > 60 mg/dL and PaO2 scale scores and the presence of complications or mortality. The Legionella urinary antigen test permits early diagnosis and treatment of this disease. The severity scale is an indicator of complications or death.

    Full Text Available Background: Community-acquired pneumonia (CAP is an important childhood killer. Excessive production of cytokines, including interleukin-6 (IL-6, might be associated with severe disease course but pediatric data is limited. Aim: To assess value of IL-6 in predicting CAP severity in children. Methods: A prospective study conducted on 73 children hospitalized for CAP and 15 healthy controls. Pneumonia severity was evaluated according to World Health Organization (WHO classification, Respiratory Index of Severity Score (RISC, Predisposition, Insult, Response, Organ dysfunction modified (PIROm score, and Pediatric Respiratory Severity Score (PRESS. Serum IL-6 was measured within 24 h of admission. The primary outcome was occurrence of any pneumonia complications or death within 30 days. Results: IL-6 was significantly higher among patients compared with controls. Unlike CRP, IL-6 was significantly higher among children with severe pneumonia as determined by WHO, PRESS, and RISC (p = 0.001 for all. IL-6 was significantly higher among children with PICU admission, mechanical ventilation, shock (p = 0.001 for all, hypoxia (p < 0.001, and lobar consolidation (p = 0.042. IL-6 had positive correlations with PRESS (rs=0.8, P < 0.001, RISC (rs=0.6, p < 0.001, and PIROm (rs=0.59, p < 0.001 while a negative correlation was found with Oxygen saturation [r = −0.61, p = 0.001]. IL-6 was not significantly correlated with CRP. Receiver Operating Characteristic curve (ROC analysis revealed large area under the curve (AUC of IL-6 for prediction of severe pneumonia as classified by WHO, PRESS, and RISC (AUC = 0.95, 0.94, and 0.89 respectively. Conclusion: IL-6 appears to be valuable for assessment of CAP severity in children compared with conventional biomarkers.

    This is the first published case report en Colombia about pseudomona pseudomallei community acquired pneumonia. This uncommon pathogen is from the epidemiological standpoint a very important one and medical community should be aware to look after it in those patients where no other etiological pathogen is recovered. A brief summary about epidemiology is showed, emphasizing those regions where it can be found. Likewise, comments about the differential diagnosis are important since it should be considered in those patients where tuberculosis is suspected. This is particularly representative for countries with high tuberculosis rates. Furthermore, a microbiological review is shown, emphasizing on isolation techniques, descriptions about therapeutics and other regarding treatment issues according international standards. Finally; a description about the clinical picture, laboratory findings, treatment and evolution of the case reported are shown for discussion

    Full Text Available Introduction: Community acquired pneumonia (CAP may present as life-threatening infection with uncertain progression and outcome of treatment. Primary aim of the trial was determination of the cut-off value of serum interleukin-6 (IL-6 and procalcitonin (PCT above which, 30-day mortality in hospitalized patients with CAP, could be predicted with high sensitivity and specificity. We investigated correlation between serum levels of IL-6 and PCT at admission and available scoring systems of CAP (pneumonia severity index-PSI, modified early warning score-MEWS and (Confusion, Urea nitrogen, respiratory rate, Blood pressure, ≥65 years of age-CURB65. Methods: This was prospective, non-randomized trial which included 101 patients with diagnosed CAP. PSI, MEWS and CURB65 were assessed on first day of hospitalization. IL-6 and PCT were also sampled on the first day of hospitalization. Results: Based on ROC curve analysis (AUC ± SE = 0.934 ± 0.035; 95%CI(0.864-1.0; P = 0.000 hospitalized CAP patients with elevated IL-6 level have 93.4% higher risk level for lethal outcome. Cut-off value of 20.2 pg/ml IL-6 shows sensitivity of 84% and specificity of 87% in mortality prediction. ROC curve analysis confirmed significant role of procalcitonin as a mortality predictor in CAP patients (AUC ± SE = 0.667 ± 0.062; 95%CI(0.546-0.789; P = 0.012. Patients with elevated PCT level have 66.7% higher risk level for lethal outcome. As a predictor of mortality at the cut-off value of 2.56 ng/ml PCT shows sensitivity of 76% and specificity of 61.8%. Conclusions: Both IL-6 and PCI are significant for prediction of 30-day mortality in hospitalized patients with CAP. Serum levels of IL6 correlate with major CAP scoring systems.

    Full Text Available Pneumonia is an important cause of morbidity and mortality among children throughout the world. Vaccines are available for some organisms, but they are underutilized and/or still in development. To evaluate the potential impact of vaccines, we review studies in which the etiology of childhood community-acquired pneumonia was recorded. In North America and Europe (9 studies, the etiology of pneumonia was established in 62% of studied children (range 43%-88% by use of noninvasive specific methods for microbiologic diagnosis. The most often identified agents were S. pneumoniae (22%, respiratory syncytial virus (RSV (20%, Haemophilus influenzae (7%, and Mycoplasma pneumoniae (15%. In Africa and South America (8 studies, bacteria were recovered from 56% (range 32%-68% of severely ill children studied by lung aspirate. The most often isolated bacteria were Streptococcus pneumoniae (33% and Haemophilus influenzae (21%. A high percentage of H. influenzae strains were not serotype b. Throughout the world, children requiring hospitalization were most likely to have infection caused by pneumococcus H. influenzae or RSV. Out patients also had Mycoplasma pneumoniae. Countries in Africa and Asia recorded 2 to 10 times more children with pneumonia (7 to 40/100 annually than in the USA. Widespread use of pneumococcal and H. influenzae type b conjugate vaccines could reduce the frequency of childhood pneumonia by one-third. Further reduction will require development of non-type b H. influenzae, RSV and M. pneumoniae vaccines. This could result in a > 50% reduction of pneumonia in children. This goal should be sought and achieved as soon as possible.

    Our objective was to identify clinical predictors of antibiotic treatment effects in hospitalized patients with community-acquired pneumonia (CAP) who were not in the intensive care unit (ICU). Post-hoc analysis of three prospective cohorts (from the Netherlands and Spain) of adult patients with CAP admitted to a non-ICU ward having received either β-lactam monotherapy, β-lactam + macrolide, or a fluoroquinolone-based therapy as empirical antibiotic treatment. We evaluated candidate clinical predictors of treatment effects in multiple mixed-effects models by including interactions of the predictors with empirical antibiotic choice and using 30-day mortality, ICU admission and length of hospital stay as outcomes. Among 8562 patients, empirical treatment was β-lactam in 4399 (51.4%), fluoroquinolone in 3373 (39.4%), and β-lactam + macrolide in 790 (9.2%). Older age (interaction OR 1.67, 95% CI 1.23-2.29, p 0.034) and current smoking (interaction OR 2.36, 95% CI 1.34-4.17, p 0.046) were associated with lower effectiveness of fluoroquinolone on 30-day mortality. Older age was also associated with lower effectiveness of β-lactam + macrolide on length of hospital stay (interaction effect ratio 1.14, 95% CI 1.06-1.22, p 0.008). Older age and smoking could influence the response to specific antibiotic regimens. The effect modification of age and smoking should be considered hypothesis generating to be evaluated in future trials.

    Full Text Available Community-acquired pneumonia (CAP is common among children and may have viral, bacterial or, occasionally, other causes. The etiology is complex, with age-related trends, and differs from that in adult CAP, necessitating different management guidelines. There is an absence of current guidelines for the management of pediatric CAP (PCAP that take into account changing etiologies, antimicrobial-resistance issues and the use of newly licensed antimicrobials. The present review does not provide specific guidelines, but it reviews the literature and presents currrent approaches to the treatment of PCAP. To compile the review, an expert panel was convened to provide a consensus. The review discusses the etiology, diagnosis and antimicrobial treatment of PCAP as well as indications for referral to a hospital emergency department. The goal of the review is to provide those involved with treatment of PCAP in the community setting with information that can be used to make effective treatment choices.

    Previous reports have shown that vaccination rates of adult at-risk populations are low in Turkey. There are differing reports with regards to the effectiveness of the influenza and the pneumococcal polysaccharide vaccine (PPSV23) on the clinical outcomes of community acquired pneumonia (CAP). The purpose of this study was to analyze the influenza (FV) and pneumococcal vaccination (PV) status, the factors that influence the receipt of influenza/pneumococcal vaccine and the effects of prior vaccination on the clinical outcomes in adults hospitalized with CAP. Patients hospitalized with CAP between March 2009 and October 2013 and registered at the web-based Turkish Thoracic Society Pneumonia Database (TURCAP) were included in this multicentric, observational study. Of a total of 787 cases, data were analyzed for 466 patients for whom self-reported information on PV and FV was available. In this adult population with CAP, the vaccination rate with both the pneumococcal and influenza vaccines was found to be 6%. Prior FV was found to be the sole variable that was associated with the receipt of PV [OR 17.8, 95% CI (25-75:8.56-37.01), p pneumonia severity index (PSI) score ≥ 90, CURB-65 score ≥3 and multilobar involvement, but not the vaccination status, were identified as independent determinants of ICU admission. This study showed that, among patients hospitalized with CAP, the FV and/or PV rates are low. Prior vaccination does not appear to significantly affect the clinical outcomes.

    Pneumonia is a common infection, accounting for approximately one million hospitalizations in the United States annually. This potentially life-threatening disease is commonly diagnosed based on history, physical examination, and chest radiograph. To investigate emergency medicine evaluation of community-acquired pneumonia including history, physical examination, imaging, and the use of risk scores in patient assessment. Pneumonia is the number one cause of death from infectious disease. The condition is broken into several categories, the most common being community-acquired pneumonia. Diagnosis centers on history, physical examination, and chest radiograph. However, all are unreliable when used alone, and misdiagnosis occurs in up to one-third of patients. Chest radiograph has a sensitivity of 46-77%, and biomarkers including white blood cell count, procalcitonin, and C-reactive protein provide little benefit in diagnosis. Biomarkers may assist admitting teams, but require further study for use in the emergency department. Ultrasound has shown utility in correctly identifying pneumonia. Clinical gestalt demonstrates greater ability to diagnose pneumonia. Clinical scores including Pneumonia Severity Index (PSI); Confusion, blood Urea nitrogen, Respiratory rate, Blood pressure, age 65 score (CURB-65); and several others may be helpful for disposition, but should supplement, not replace, clinical judgment. Patient socioeconomic status must be considered in disposition decisions. The diagnosis of pneumonia requires clinical gestalt using a combination of history and physical examination. Chest radiograph may be negative, particularly in patients presenting early in disease course and elderly patients. Clinical scores can supplement clinical gestalt and assist in disposition when used appropriately. Published by Elsevier Inc.

    Community acquired pneumonia remains a common cause of morbidity and mortality. Usually, the causal organism is not identified and treatment remains empiric. Recent computed tomography and magnetic resonance imaging studies have challenged the accuracy of the clinical diagnosis of pneumonia, and epidemiologic studies are changing our perspective of what causes community acquired pneumonia, especially the role of viral pathogens and the frequent finding of multiple pathogens. The past decade has seen increasing overuse of empiric coverage of meticillin resistant Staphylococcus aureus and antibiotic resistant Gram negative pathogens owing to inappropriate application of guidelines for healthcare associated pneumonia. Optimal treatment remains a matter for debate, especially in very sick patients, including the role of combination antibiotic therapy and corticosteroids. Pneumonia care bundles are being defined to improve outcomes. Increased recognition of both acute and long term cardiac complications is shifting our concept of pneumonia from an acute lung disease to a multisystem problem with adverse chronic health consequences.

    Full Text Available Qualitative assessment of diagnostics and treatment of patients with community-acquired pneumonia (CAP was carried out in ten therapeutic departments of urban and district hospitals of Saratov region, using quality indicators (Qls. Each case of CAP was assessed in expert health care quality (HCQ card according to the diagnostic and treatment quality federal standards and the basic Ql. The application of Ql in CAP patients allowed revealing the following: low CAP agent isolation rate; late hospitalization of CAP patients; low frequency of sputum bacteriological and bacterioscopic investigations prior to antibiotic therapy; insufficient frequency of step-by-step introduction of antibiotics. Recommendations on CAP patients dispenserization were not properly prescribed; recommendations on vaccination were absent. The basic measures of HCQ improvement are as follows: organizing for each CAP patient therapeutic and diagnostic quality control according to Ql; quick administrative decisions; using of HCQ expertise during the first 2-3 days of treatment to correct diagnosis and treatment; optimizing hospital diagnostic resources (laboratory and instrumental and rational pharmacotherapy

    Full Text Available Abstract Background Patients hospitalized with community acquired pneumonia (CAP have a substantial risk of death, but there is evidence that adherence to certain processes of care, including antibiotic administration within 8 hours, can decrease this risk. Although national mortality data shows blacks have a substantially increased odds of death due to pneumonia as compared to whites previous studies of short-term mortality have found decreased mortality for blacks. Therefore we examined pneumonia-related processes of care and short-term mortality in a population of patients hospitalized with CAP. Methods We reviewed the records of all identified Medicare beneficiaries hospitalized for pneumonia between 10/1/1998 and 9/30/1999 at one of 101 Pennsylvania hospitals, and randomly selected 60 patients at each hospital for inclusion. We reviewed the medical records to gather process measures of quality, pneumonia severity and demographics. We used Medicare administrative data to identify 30-day mortality. Because only a small proportion of the study population was black, we included all 240 black patients and randomly selected 720 white patients matched on age and gender. We performed a resampling of the white patients 10 times. Results Males were 43% of the cohort, and the median age was 76 years. After controlling for potential confounders, blacks were less likely to receive antibiotics within 8 hours (odds ratio with 95% confidence interval 0.6, 0.4–0.97, but were as likely as whites to have blood cultures obtained prior to receiving antibiotics (0.7, 0.3–1.5, to have oxygenation assessed within 24 hours of presentation (1.6, 0.9–3.0, and to receive guideline concordant antibiotics (OR 0.9, 0.6–1.7. Black patients had a trend towards decreased 30-day mortality (0.4, 0.2 to 1.0. Conclusion Although blacks were less likely to receive optimal care, our findings are consistent with other studies that suggest better risk-adjusted survival

  14. An Update on the Management Of Hospital-Acquired Pneumonia in the Elderly

    Full Text Available Pneumonia is the leading cause of infection-related death and represents the fifth cause of mortality in the elderly. There are several reported risk factors for acquiring pneumonia at an older age, such as alcoholism, lung and heart diseases, nursing home residence, and swallowing disorders. Hospital-acquired pneumonia (HAP is reviewed, with an emphasis on multidrug-resistant (MDR bacterial pathogens, such as Pseudomonas aeruginosa, Acinetobacter species, and methicillin-resistant Staphylococcus aureus. The clinical characteristics of pneumonia in the elderly differ substantially compared with younger patients, and the severity of the disease is strongly associated with increased age and age-related comorbid disorders. Streptococcus pneumoniae is the pathogen most frequently responsible for pneumonia in the elderly with early HAP without risk factors for MDR; enteric Gram-negative rods should be considered in nursing home-associated pneumonia, as well as anaerobes in patients with aspiration pneumonia. Special attention should be given to preventive measures such as vaccination, oral care, and nutrition. The management of HAP should be instituted early with: appropriate use of antibiotics in adequate doses; avoidance of excessive use of antibiotics by de-escalation of initial antibiotic therapy, based on microbiologic cultures and the clinical response of the patient; and reduction of the duration of treatment to the minimum effective period.

    The aim of this study was to quantify the value of clinical predictors available in the emergency department (ED) in predicting Streptococcus pneumoniae as the cause of community-acquired pneumonia (CAP). A prospective, observational, cohort study of patients with CAP presenting in the ED was performed. Pneumococcal aetiology of CAP was based on either bacteraemia, or S. pneumoniae being cultured from sputum, or urinary immunochromatographic assay positivity, or positivity of a novel serotype-specific urinary antigen detection test. Multivariate logistic regression was used to identify independent predictors and various cut-off values of probability scores were used to evaluate the usefulness of the model. Three hundred and twenty-eight (31.0%) of 1057 patients with CAP had pneumococcal CAP. Nine independent predictors for pneumococcal pneumonia were identified, but the clinical utility of this prediction model was disappointing, because of low positive predictive values or a small yield. Clinical criteria have insufficient diagnostic capacity to predict pneumococcal CAP. Rapid antigen detection tests are needed to diagnose S. pneumoniae at the time of hospital admission. © 2014 The Authors Clinical Microbiology and Infection © 2014 European Society of Clinical Microbiology and Infectious Diseases.

    2017-04-01

    Adherence to antimicrobial guidelines for empiric antibiotic prescribing in community-acquired pneumonia (CAP) has been reported to be worryingly low. We conducted a review of empiric antibiotic prescribing for sixty consecutive adult patients admitted to the Mercy University Hospital with a diagnosis of CAP. When analysed against local antimicrobial guidelines, guideline concordant empiric antibiotics were given in only 48% of cases, lower than the average rate in comparable studies. Concordance was 100% in cases where the CURB-65 pneumonia severity assessment score, on which the guidelines are based, was documented in the medical notes. The use of excessively broad spectrum and inappropriate antibiotics is a notable problem. This study supports the theory that lack of knowledge regarding pneumonia severity assessment tools and unfamiliarity with therapeutic guidelines are key barriers to guideline adherence, which remains a significant problem despite increased focus on antimicrobial stewardship programs in Ireland

    Background Although viruses are known to be the second most common etiological factor in community-acquired pneumonia (CAP), the respiratory viral profile of the patients with healthcare-associated pneumonia (HCAP) has not yet been elucidated. We investigated the prevalence and the clinical impact of respiratory virus infection in adult patients with HCAP. Methods Patients admitted with HCAP or CAP, between January and December 2016, to a tertiary referral hospital in Korea, were prospectively enrolled, and virus identification was performed using reverse-transcription polymerase chain reaction (RT-PCR). Results Among 452 enrolled patients (224 with HCAP, 228 with CAP), samples for respiratory viruses were collected from sputum or endotracheal aspirate in 430 (95.1%) patients and from nasopharyngeal specimens in 22 (4.9%) patients. Eighty-seven (19.2%) patients had a viral infection, and the proportion of those with viral infection was significantly lower in the HCAP than in the CAP group (13.8% vs 24.6%, p = 0.004). In both the HCAP and CAP groups, influenza A was the most common respiratory virus, followed by entero-rhinovirus. The seasonal distributions of respiratory viruses were also similar in both groups. In the HCAP group, the viral infection resulted in a similar length of hospital stay and in-hospital mortality as viral–bacterial coinfection and bacterial infection, and the CAP group showed similar results. Conclusions The prevalence of viral infection in patients with HCAP was lower than that in patients with CAP, and resulted in a similar prognosis as viral–bacterial coinfection or bacterial infection.

    The clinical significance of pneumonia visualized on CT scan in the setting of a normal chest radiograph is uncertain. In a multicenter prospective surveillance study of adults hospitalized with community-acquired pneumonia (CAP), we compared the presenting clinical features, pathogens present, and outcomes of patients with pneumonia visualized on a CT scan but not on a concurrent chest radiograph (CT-only pneumonia) and those with pneumonia visualized on a chest radiograph. All patients underwent chest radiography; the decision to obtain CT imaging was determined by the treating clinicians. Chest radiographs and CT images were interpreted by study-dedicated thoracic radiologists blinded to the clinical data. The study population included 2,251 adults with CAP; 2,185 patients (97%) had pneumonia visualized on chest radiography, whereas 66 patients (3%) had pneumonia visualized on CT scan but not on concurrent chest radiography. Overall, these patients with CT-only pneumonia had a clinical profile similar to those with pneumonia visualized on chest radiography, including comorbidities, vital signs, hospital length of stay, prevalence of viral (30% vs 26%) and bacterial (12% vs 14%) pathogens, ICU admission (23% vs 21%), use of mechanical ventilation (6% vs 5%), septic shock (5% vs 4%), and inhospital mortality (0 vs 2%). Adults hospitalized with CAP who had radiological evidence of pneumonia on CT scan but not on concurrent chest radiograph had pathogens, disease severity, and outcomes similar to patients who had signs of pneumonia on chest radiography. These findings support using the same management principles for patients with CT-only pneumonia and those with pneumonia seen on chest radiography.

    We herein report the case of 75-year-old Japanese female with a community-acquired lung abscess attributable to Streptococcus pneumoniae (S. penumoniae) which extended into the chest wall. The patient was admitted to our hospital with a painful mass on the left anterior chest wall. A contrast-enhanced chest computed tomography scan showed a lung abscess in the left upper lobe which extended into the chest wall. Surgical debridement of the chest wall abscess and percutaneous transthoracic tube drainage of the lung abscess were performed. A culture of the drainage specimen yielded S. pneumoniae. The patient showed a remarkable improvement after the initiation of intravenous antibiotic therapy.

    Full Text Available Summary Objective: several scores were developed in order to improve the determination of community acquired pneumonia (CAP severity and its management, mainly CURB-65 and SACP score. However, none of them were evaluated for risk assessment of in-hospital mortality, particularly in individuals who were non-immunosuppressed and/or without any comorbidity. In this regard, the present study was carried out. Methods: we performed a cross-sectional study in 272 immunocompetent patients without comorbidities and with a diagnosis of CAP. Performance of CURB- 65 and SCAP scores in predicting in-hospital mortality was evaluated. Also, variables related to death were assessed. Furthermore, in order to design a model of in-hospital mortality prediction, sampled individuals were randomly divided in two groups. The association of the variables with mortality was weighed and, by multiple binary regression, a model was constructed in one of the subgroups. Then, it was validated in the other subgroup. Results: both scores yielded a fair strength of agreement, and CURB-65 showed a better performance in predicting in-hospital mortality. In our casuistry, age, white blood cell counts, serum urea and diastolic blood pressure were related to death. The model constructed with these variables showed a good performance in predicting in-hospital mortality; moreover, only one patient with fatal outcome was not correctly classified in the group where the model was constructed and in the group where it was validated. Conclusion: our findings suggest that a simple model that uses only 4 variables, which are easily accessible and interpretable, can identify seriously ill patients with CAP

    The usefulness of sputum Gram stain in patients with community-acquired pneumonia (CAP) is controversial. There has been no study to evaluate the diagnostic value of this method in patients with healthcare-associated pneumonia (HCAP). The purpose of this study was to evaluate the usefulness of sputum Gram stain in etiological diagnosis and pathogen-targeted antibiotic treatment of CAP and HCAP. We conducted a prospective observational study on hospitalized patients with pneumonia admitted to our hospital from August 2010 to July 2012. Before administering antibiotics on admission, Gram stain was performed and examined by trained physicians immediately after sputum samples were obtained. We analyzed the quality of sputum samples and the diagnostic performance of Gram stain. We also compared pathogen-targeted antibiotic treatment guided by sputum Gram stain with empirical treatment. Of 670 patients with pneumonia, 328 were CAP and 342 were HCAP. Sputum samples were obtained from 591 patients, of these 478 samples were good quality. The sensitivity and specificity of sputum Gram stain were 62.5% and 91.5% for Streptococcus pneumoniae, 60.9% and 95.1% for Haemophilus influenzae, 68.2% and 96.1% for Moraxella catarrhalis, 39.5% and 98.2% for Klebsiella pneumoniae, 22.2% and 99.8% for Pseudomonas aeruginosa, 9.1% and 100% for Staphylococcus aureus. The diagnostic yield decreased in patients who had received antibiotics or patients with suspected aspiration pneumonia. Pathogen-targeted treatment provided similar efficacy with a decrease in adverse events compared to empirical treatment. Sputum Gram stain is highly specific for the etiologic diagnosis and useful in guiding pathogen-targeted antibiotic treatment of CAP and HCAP.

    Early recognition and an attempt at obtaining microbiological documentation are recommended in patients with non-community-acquired pneumonia (NCAP), whether hospital-acquired (HAP) or health care-associated (HCAP). We aimed to characterize the clinical features and microbial etiologies of NCAP to assess the impact of microbiological investigation on their management. This was a prospective 1-y study in a university hospital with 141 non-mechanically ventilated subjects suspected of having HAP (n = 110) or HCAP (n = 31). Clinical criteria alone poorly identified pneumonia (misdiagnosis in 50% of cases). Microbiological confirmation was achievable in 80 subjects (57%). Among 79 microorganisms isolated, 28 were multidrug-resistant aerobic Gram-negative bacilli and group III Enterobacteriaceae and 6 were methicillin-resistant Staphylococcus aureus. Multidrug-resistant aerobic Gram-negative bacilli accounted for one third of the microorganisms in early-onset HAP and for 50% in late-onset HAP. Methicillin-resistant S. aureus was most often recovered from subjects with HCAP. Inappropriate empirical antibiotics were administered to 36% of subjects with confirmed pneumonia. Forty subjects were admitted to the ICU, 13 (33%) of whom died. Overall, 39 subjects (28%) died in the hospital. Integrating the microbiological investigation in the complex clinical diagnostic workup of patients suspected of having NCAP is mandatory. Respiratory tract specimens should be obtained whenever possible for appropriate management. Copyright © 2016 by Daedalus Enterprises.

To determinate the prevalence rates of Chlamydia pneumoniae infections in Slovenia and to evaluate the importance of C. pneumoniae infections at patients with community acquired pneumonia (CAP.Materials and methods. With the microimmunofluorescence test (micro-IF we evaluated the presence of C. pneumoniae specific antibodies in 1036 healthy subjects, in two periods of time, in 1991–93 and 1997–1998. We also tested the pair sera collected from 2118 patients with CAP between 1993–1999.Results. We demonstrated that C. pneumoniae infections are common in our population, as we detected IgG antibodies in 43.1% of healthy population. The prevalence rate of C. pneumoniae infections statistically significant increased in two periods of time. Acute C. pneumoniae infections were proved in 15.9% of all patients with CAP.Conclusions. C. pneumoniae is important respiratory pathogen also in our community. The infections are more common in older patients. Because C. pneumoniae like other Chlamydia species has tendency to cause chronic disease, it is reasonable to diagnose this bacterium in respiratory patients. It is also recommended to test convalescent sera at serologic laboratory diagnosis.

    Admission blood pressure (BP) assessment is a central component of severity assessment for community acquired pneumonia. The aim of this study was to establish which readily available haemodynamic measure on admission is most useful for predicting severity in patients admitted with community acquired pneumonia. A prospective observational study of patients admitted with community acquired pneumonia was conducted in Edinburgh, UK. The measurements compared were systolic and diastolic BP, mean arterial pressure and pulse pressure. The outcomes of interest were 30 day mortality and the requirement for mechanical ventilation and/or inotropic support. Admission systolic BP pressure pressure AUC values for each predictor of 30 day mortality were as follows: systolic BP pressure pressure AUC values for each predictor of need for mechanical ventilation and/or inotropic support were as follows: systolic BP pressure pressure blood pressure AUC 0.76 vs 0.74) and to the standard CURB65 score (0.76 vs 0.76) for the prediction of 30 day mortality. The simplified CRB65 score was equivalent for prediction of mechanical ventilation and/or inotropic support to standard CRB65 (0.77 vs 0.77) and to CURB65 (0.77 vs 0.78). Systolic BP is superior to other haemodynamic predictors of 30 day mortality and need for mechanical ventilation and/or inotropic support in community acquired pneumonia. The CURB65 score can be simplified to a modified CRB65 score by omission of the diastolic BP criterion without compromising its accuracy.

    To determine 1) the cost of hospitalization, the 1-week postdischarge cost, the total cost, and the economic burden of community-acquired pneumonia among patients aged 19 years or older in the Philippines and 2) the difference between the estimated costs and the Philippine Health Insurance Corporation (PhilHealth) pneumonia case rate payments. The study involved two tertiary private hospitals in the Philippines. Using the societal perspective, both health care and non-health care costs were determined. A base-case analysis and sensitivity analyses were performed, and the economic burden of pneumonia was determined using PhilHealth claims. The estimated cost of hospitalization for community-acquired pneumonia-moderate risk (CAP-MR) ranged from Philippine peso (PHP) 36,153 to 113,633 (US $852-2678) and its 1-week postdischarge cost ranged from PHP1450 to 8800 (US $34-207). The cost of hospitalization for community-acquired pneumonia-high risk (CAP-HR) ranged from PHP104,544 to 249,695 (US $2464-5885) and PHP101,248 to 243, 495 (US $2386-5739) using invasive and noninvasive ventilation, respectively. The postdischarge cost for CAP-HR ranged from PHP1716 to 10,529 (US $40-248). If only health care cost was considered, the cost ranged from PHP24,403 to 89,433 for CAP-MR and PHP92,848 to 213,395 for CAP-HR. The present PhilHealth case rate payments are PHP15,000 (US $354) and PHP32,000 (US $754) for CAP-MR and CAP-HR, respectively. Based on the number of PhilHealth claims for 2012 and the estimated health care cost, the economic burden of pneumonia in 2012 was PHP8.48 billion for CAP-MR and PHP643.76 million for CAP-HR. The estimated health care cost of hospitalization is markedly higher than the PhilHealth case rate payments. As per the study results, the economic burden of pneumonia is, thus, significantly higher than PhilHealth estimates.

    To obtain the baseline data on the incidence and cost of community acquired pneumonia among under-5 children for future studies, and provide evidence for shaping China's strategies regarding pneumococcal conjugate vaccine (PCV). Three townships from Heilongjiang, Hebei and Gansu Province and one community in Shanghai were selected as study areas. A questionnaire survey was conducted to collect data on incidence and cost of pneumonia among children under 5 y old in 2012. The overall incidence of clinically diagnosed pneumonia in children under 5 y old was 2.55%. The incidence in urban area was 7.97%, higher than that in rural areas (1.68%). However, no difference was found in the incidences of chest X-ray confirmed pneumonia between urban and rural areas (1.67% vs 1.23%). X-ray confirmed cases in rural and urban areas respectively accounted for 73.45% and 20.93% of all clinically diagnosed pneumonia. The hospitalization rate of all cases was 1.40%. Incidence and hospitalization rate of pneumonia decreased with age, with the highest rates found among children younger than one year and the lowest among children aged 4 (incidence: 4.25% vs 0.83%; hospitalization: 2.75% vs 0.36%). The incidence was slightly higher among boys (2.92% vs 2.08%). The total cost due to pneumonia for the participants was 1138 733 CNY. The average cost and median cost was 5722 CNY and 3540 CNY separately. Multivariate analysis showed that the only factor related to higher cost was hospitalization. The disease burden was high for children under 5 y old, especially the infant. PCV has not been widely used among children, and thus further health economics evaluation on introducing PCV into National Immunization Program should be conducted.

    Poor functional status (FS) has been suggested as a poor prognostic factor in both pneumonia and severe pneumonia in elderly patients. However, it is still unclear whether FS is associated with outcomes and improves survival prediction in community-acquired pneumonia (CAP) in the general population. Data on hospitalized patients with CAP and FS, assessed by the Eastern Cooperative Oncology Group (ECOG) scale were prospectively collected between January 2008 and December 2012. The independent association of FS with 30-day mortality in CAP patients was evaluated using multivariable logistic regression. Improvement in mortality prediction when FS was added to the CRB-65 (confusion, respiratory rate, blood pressure and age 65) score was evaluated for discrimination, reclassification and calibration. The 30-day mortality of study participants (n = 1526) was 10%. Mortality significantly increased with higher ECOG score (P for trend <0.001). In multivariable analysis, ECOG ≥3 was strongly associated with 30-day mortality (adjusted OR: 5.70; 95% CI: 3.82-8.50). Adding ECOG ≥3 significantly improved the discriminatory power of CRB-65. Reclassification indices also confirmed the improvement in discrimination ability when FS was combined with the CRB-65, with a categorized net reclassification index (NRI) of 0.561 (0.437-0.686), a continuous NRI of 0.858 (0.696-1.019) and a relative integrated discrimination improvement in the discrimination slope of 139.8 % (110.8-154.6). FS predicted 30-day mortality and improved discrimination and reclassification in consecutive CAP patients. Assessment of premorbid FS should be considered in mortality prediction in patients with CAP. © 2017 Asian Pacific Society of Respirology.

    Previous studies have shown that carbon monoxide, which is endogenously produced, is increased in community-acquired pneumonia (CAP). However, it has not been studied enough whether severity of pneumonia is correlated with increased carboxyhemoglobin (COHb) concentrations in CAP. The aim of this study was to determine whether endogenous carbon monoxide levels in patients with CAP were higher compared with the control group and, if so, to determine whether COHb concentrations could predict severity in CAP. Eighty-two patients with CAP were evaluated in this cross-sectional study during a 10-month period. Demographic data, pneumonia severity index and confusion, uremia, rate respiratory, pressure blood, age>65 (CURB-65) scores, hospital admission or discharge decisions, and 30-day hospital mortality rate were recorded. In addition, 83 control subjects were included to study. The COHb concentration was measured in arterial blood sample. The levels of COHb in patients with CAP were 1.70% (minimum-maximum, 0.8-3.2), whereas those in control subjects, 1.40% (minimum-maximum, 0.8-2.9). The higher COHb concentrations in patients with CAP were statistically significant (P < .05). Concentration of COHb correlated with pneumonia severity index (P = .04, r = 0.187); however, it did not correlate with CURB-65 (P = .218, r = 0.112). Although COHb concentrations show an increase in patients with pneumonia, it was concluded that this increase did not act as an indicator in diagnosis process or prediction of clinical severity for the physicians.

    Full Text Available Abstract Background The impact of HIV infection on the evolution of acute community-acquired pneumonia (CAP is still controversial. The aim of this study was to investigate possible differences in the clinical presentation and in-hospital outcomes of patients with CAP with and without HIV infection in a specialised service in Yaounde. Methods Medical files of 106 patients (51 men aged 15 years and above, admitted to the Pneumology service of the Yaounde Jamot Hospital between January 2008 and May 2012, were retrospectively studied. Results Sixty-two (58.5% patients were HIV infected. The median age of all patients was 40 years (interquartile range: 31.75-53 and there was no difference in the clinical and radiological profile of patients with and without HIV infection. The median leukocyte count (interquartile range was 14,600/mm3 (10,900-20,600 and 10,450/mm3 (6,400-16,850 respectively in HIV negative and HIV positive patients (p = 0.002. Median haemoglobin level (interquartile range was 10.8 g/dl (8.9-12 in HIV negative and 9.7 g/dl (8–11.6 in HIV positive patients (p = 0.025. In-hospital treatment failure on third day (39.5% vs. 25.5.1%, p = 0.137 and mortality rates (9% vs. 14.5%, p = 0.401 were similar between HIV negative and HIV positive patients. Conclusion Clinical and radiological features as well as response to treatment and in hospital fatal outcomes are similar in adult patients hospitalised with acute community-acquired pneumonia in Yaounde. In contrast, HIV infected patients tend to be more anaemic and have lower white cell counts than HIV negative patients. Larger prospective studies are needed to consolidate these findings.

    We investigated rates and predictors of ventilatory support during hospitalization in seemingly not severely compromised nonsurvivors of community-acquired pneumonia (CAP). We used the database from the German nationwide mandatory quality assurance program including all hospitalized patients with CAP from 2007 to 2011. We selected a population not residing in nursing homes, not bedridden, and not referred from another hospital. Predictors of ventilatory support were identified using a multivariate analysis. Overall, 563,901 patients (62.3% of the whole population) were included. Mean age was 69.4 ± 16.6 years; 329,107 (58.4%) were male. Mortality was 39,895 (7.1%). A total of 28,410 (5.0%) received ventilatory support during the hospital course, and 76.3% of nonsurvivors did not receive ventilatory support (62.6% of those aged ventilatory support during hospitalization. Death from CAP occurred significantly earlier in the nonventilated group (8.2 ± 8.9 vs. 13.1 ± 14.1 days; p ventilatory support is disturbingly high, particularly in younger patients. Both performance predictors for not being ventilated remain ambiguous, because they may reflect either treatment restrictions or deficient clinical performance. Elucidating this ambiguity will be part of the forthcoming update of the quality assurance program.

    Objective To assess the adherence to Infectious Disease Society of America/American Thoracic Society guidelines and the causes of lack of adherence during empirical antibiotic prescription in severe pneumonia in Latin America. Methods A clinical questionnaire was submitted to 36 physicians from Latin America; they were asked to indicate the empirical treatment in two fictitious cases of severe respiratory infection: community-acquired pneumonia and nosocomial pneumonia. Results In the case of communityacquired pneumonia, 11 prescriptions of 36 (30.6%) were compliant with international guidelines. The causes for non-compliant treatment were monotherapy (16.0%), the unnecessary prescription of broad-spectrum antibiotics (40.0%) and the use of non-recommended antibiotics (44.0%). In the case of nosocomial pneumonia, the rate of adherence to the Infectious Disease Society of America/American Thoracic Society guidelines was 2.8% (1 patient of 36). The reasons for lack of compliance were monotherapy (14.3%) and a lack of dual antibiotic coverage against Pseudomonas aeruginosa (85.7%). If monotherapy with an antipseudomonal antibiotic was considered adequate, the antibiotic treatment would be adequate in 100% of the total prescriptions. Conclusion The compliance rate with the Infectious Disease Society of America/American Thoracic Society guidelines in the community-acquired pneumonia scenario was 30.6%; the most frequent cause of lack of compliance was the indication of monotherapy. In the case of nosocomial pneumonia, the compliance rate with the guidelines was 2.8%, and the most important cause of non-adherence was lack of combined antipseudomonal therapy. If the use of monotherapy with an antipseudomonal antibiotic was considered the correct option, the treatment would be adequate in 100% of the prescriptions. PMID:25909312

    Important hospital-acquired infections include pneumonia, mainly because of the increasing resistance of bacterial pathogens to antimicrobials and the associated potential failure of antibiotic therapy. The present study aimed at determining the most frequent etiological agents of hospital-acquired pneumonia (HAP) and assessing the relationship between 30-day mortality and adequacy of antibiotic therapy. Based on the obtained information, optimal patterns of antibiotic therapy were to be defined, including a pharmacoeconomic perspective. In patients with clinically confirmed HAP, bacterial etiological agents were identified, their susceptibility to antimicrobials was determined and statistical methods were used to assess the relationship between adequacy of antibiotic therapy and 30-day mortality. The study comprised 68 patients with clinically confirmed HAP. The most common etiological agents were strains of Pseudomonas aeruginosa (30.8 %), Klebsiella pneumoniae (23.1 %) and Burkholderia cepacia complex (15.4 %). Gram-negative bacteria accounted for 86.5 % of all bacterial pathogens. The overall mortality reached 42.5 %. In the subgroup of patients with inadequate antibiotic therapy, 30-day mortality was significantly higher (83.3 %) than in the subgroup with adequate therapy (30.0 %; p = 0.002). The risk for 30-day mortality was 2.78 times higher in case of inadequate antibiotic therapy (95%CI: 1.52-5.07). The proportion of Pseudomonas aeruginosa strains was significantly higher in the subgroup of patients with inadequate antibiotic therapy than in those with adequate therapy (67 % vs. 27 %; p = 0.032). Results of the present study suggest a significant relationship between mortality of patients with HAP and ineffective antibiotic therapy due to resistance of the bacterial pathogen. Thus, it is clear that initial antibiotic therapy must be based on qualified assumption of sufficient activity against the most common bacterial pathogens and results of surveillance

    Streptococcus pneumoniae is the most common cause of community-acquired pneumonia, but it is undoubtedly underdiagnosed. We used a nested PCR assay (targeting the pneumolysin gene) to detect S. pneumoniae DNA in multiple sample types from 474 adults with community-acquired pneumonia and 183 control patients who did not have pneumonia. Plasma or buffy coat samples were PCR positive in only 6 of the 21 patients with positive blood cultures for S. pneumoniae and in 12 other patients (4 of whom had no other laboratory evidence of S. pneumoniae infection). Buffy coat samples from two control patients (neither having evidence of S. pneumoniae infection), but no control plasma samples, were PCR positive. Although pneumococcal antigen was detected in the urine from 120 of 420 (29%) patients, only 4 of 227 (2%) urine samples tested were PCR positive. Overall, 256 of 318 (81%) patients had PCR-positive sputum samples, including 58 of 59 samples from which S. pneumoniae was cultured. Throat swab samples from 229 of 417 (55%) patients were PCR positive and, in those who produced sputum, 96% also had positive PCR results from sputum. Throat swabs from 73 of 126 (58%) control patients were also PCR positive. We conclude that the pneumolysin PCR assay adds little to existing diagnostic tests for S. pneumoniae and is unable to distinguish colonization from infection when respiratory samples are tested.

    Pneumonia Severity Index (PSI) predicts mortality better than Confusion, Urea >7 mmol/L, Respiratory rate >30/min, low Blood pressure: diastolic blood pressure blood pressure 65 years (CURB-65) for community-acquired pneumonia (CAP) but is more cumbersome. The objective was to determine whether CURB enhanced with a small number of additional variables can predict mortality with at least the same accuracy as PSI. Retrospective review of medical records and administrative data of adults aged 55 years or older hospitalized for CAP over 1 year from three hospitals. For 1052 hospital admissions of unique patients, 30-day mortality was 17.2%. PSI class and CURB-65 predicted 30-day mortality with area under curve (AUC) of 0.77 (95% confidence interval (CI): 0.73-0.80) and 0.70 (95% CI: 0.66-0.74) respectively. When age and three co-morbid conditions (metastatic cancer, solid tumours without metastases and stroke) were added to CURB, the AUC improved to 0.80 (95% CI: 0.77-0.83). Bootstrap validation obtained an AUC estimate of 0.78, indicating negligible overfitting of the model. Based on this model, a clinical score (enhanced CURB score) was developed that had possible values from 5 to 25. Its AUC was 0.79 (95% CI: 0.76-0.83) and remained similar to that of PSI class. An enhanced CURB score predicted 30-day mortality with at least the same accuracy as PSI class did among older adults hospitalized for CAP. External validation of this score in other populations is the next step to determine whether it can be used more widely. © 2012 The Authors. Respirology © 2012 Asian Pacific Society of Respirology.

    Background and objective: The management of community-acquired pneumonia (CAP) depends, in part, on the identification of the causative agents. The objective of this study was to determine the potential of thin-section computed tomography (CT) in differentiating bacterial and non-bacterial pneumonia. Patients and methods: Thin-section CT studies were prospectively examined in hospitalized CAP patients within 2 days of admission, followed by retrospective assessment by two pulmonary radiologists. Thin-section CT findings on the pneumonias caused by each pathogen were examined, and two types of pneumonias were compared. Using multivariate logistic regression analyses, receiver operating characteristic (ROC) curves were produced. Results: Among 183 CAP episodes (181 patients, 125 men and 56 women, mean age {+-} S.D.: 61.1 {+-} 19.7) examined by thin-section CT, the etiologies of 125 were confirmed (94 bacterial pneumonia and 31 non-bacterial pneumonia). Centrilobular nodules were specific for non-bacterial pneumonia and airspace nodules were specific for bacterial pneumonia (specificities of 89% and 94%, respectively) when located in the outer lung areas. When centrilobular nodules were the principal finding, they were specific but lacked sensitivity for non-bacterial pneumonia (specificity 98% and sensitivity 23%). To distinguish the two types of pneumonias, centrilobular nodules, airspace nodules and lobular shadows were found to be important by multivariate analyses. ROC curve analysis discriminated bacterial pneumonia from non-bacterial pneumonia among patients without underlying lung diseases, yielding an optimal point with sensitivity and specificity of 86% and 79%, respectively, but was less effective when all patients were analyzed together (70% and 84%, respectively). Conclusion: Thin-section CT examination was applied for the differentiation of bacterial and non-bacterial pneumonias. Though showing some potential, this examination at the present time would

    Full Text Available Abstract Background Community-acquired pneumonia (CAP is a common cause of pediatric admission to hospital. The objectives of this study were twofold: 1 to describe the clinical characteristics of CAP in children admitted to a tertiary care pediatric hospital in the pneumococcal vaccination era and, 2 to examine the antimicrobial selection in hospital and on discharge. Methods A retrospective review of healthy immunocompetent children admitted to a tertiary pediatric hospital from January 2007 to December 2008 with clinical features consistent with pneumonia and a radiographically-confirmed consolidation was performed. Clinical, microbiological and antimicrobial data were collected. Results One hundred and thirty-five hospitalized children with pneumonia were evaluated. Mean age at admission was 4.8 years (range 0–17 years. Two thirds of patients had been seen by a physician in the 24 hours prior to presentation; 56 (41.5% were on antimicrobials at admission. 52 (38.5% of patients developed an effusion, and 22/52 (42.3% had pleural fluid sampled. Of 117 children who had specimens (blood/pleural fluid cultured, 9 (7.7% had pathogens identified (7 Streptococcus pneumoniae, 1 Group A Streptococcus, and 1 Rhodococcus. 55% of patients received 2 or more antimicrobials in hospital. Cephalosporins were given to 130 patients (96.1% in hospital. Only 21/126 patients (16.7% were discharged on amoxicillin. The median length of stay was 3 days (IQR 2–4 for those without effusion and 9 (IQR 5–13 for those with effusion. No deaths were related to pneumonia. Conclusions This study provides comprehensive data on the clinical characteristics of hospitalized children with CAP in the pneumococcal 7-valent vaccine era. Empiric antimicrobial choice at our institution is variable, highlighting a need for heightened antimicrobial stewardship.

    To determine the efficacy of oral antibiotics in under-five children with pneumonia and chest indrawing. We included controlled clinical trials (randomized or quasi randomized) that compared the efficacy of oral antibiotics versus parenteral antibiotics for treatment of community acquired pneumonia with chest indrawing (severe pneumonia as defined by the World Health Organizations guidelines) in children below 60 months of age. Data were extracted and managed using RevMan software. Main outcome variables were: treatment failure rate, relapse rate, death rate, need for hospitalization, and severe adverse effects. We identified four randomized controlled trials involving 4400 children who were diagnosed to have severe pneumonia but were feeding well and not hypoxic. Baseline characteristics of children in the two treatment arms (oral and parenteral antibiotics) were similar. In two studies, oral antibiotics were administered on an ambulatory basis, while in two, oral antibiotics were used in hospitalized children. Failure rate in children receiving oral antibiotics was 13% (288/2208) while that in children receiving parenteral antibiotics was 13.8% (302/2183) (OR 0.93; 95% CI 0.78, 1.11). Failure rates were not affected by the type of oral antibiotic, or presence of wheeze. Relapse rates, hospitalization or serious adverse events were similar in the two groups. Children with tachypnea with chest indrawing without signs and symptoms of very severe pneumonia may be treated with oral antibiotics.

    Community-acquired pneumonia (CAP) is a severe infection, with high mortality. Antibiotic strategies for CAP differ across Europe. The objective of the study was to describe the epidemiology of CAP in Denmark and evaluate the prognosis of patients empirically treated with penicillin-G/V monotherapy. Retrospective cohort study including hospitalized patients with x-ray confirmed CAP. We calculated the population-based incidence, reviewed types of empiric antibiotics and duration of antibiotic treatment. We evaluated the association between mortality and treatment with empiric penicillin-G/V using logistic regression analysis. We included 1320 patients. The incidence of hospitalized CAP was 3.1/1000 inhabitants. Median age was 71 years (IQR; 58-81) and in-hospital mortality was 8%. Median duration of antibiotic treatment was 10 days (IQR; 8-12). In total 45% were treated with penicillin-G/V as empiric monotherapy and they did not have a higher mortality compared to patients treated with broader-spectrum antibiotics (OR 0.92, CI 95% 0.55-1.53). The duration of treatment exceeded recommendations in European guidelines. Empiric monotherapy with penicillin-G/V was commonly used and not associated with increased mortality in patients with mild to moderate pneumonia. Our results are in agreement with current conservative antibiotic strategy as outlined in the Danish guidelines.

    Pneumonia caused by bacterial pathogens is the leading cause of mortality in children in low-income countries. Early administration of antibiotics improves outcomes. To identify effective antibiotic drug therapies for community-acquired pneumonia (CAP) of varying severity in children by comparing various antibiotics. We searched CENTRAL 2012, Issue 10; MEDLINE (1966 to October week 4, 2012); EMBASE (1990 to November 2012); CINAHL (2009 to November 2012); Web of Science (2009 to November 2012) and LILACS (2009 to November 2012). Randomised controlled trials (RCTs) in children of either sex, comparing at least two antibiotics for CAP within hospital or ambulatory (outpatient) settings. Two review authors independently extracted data from the full articles of selected studies. We included 29 trials, which enrolled 14,188 children, comparing multiple antibiotics. None compared antibiotics with placebo.Assessment of quality of study revealed that 5 out of 29 studies were double-blind and allocation concealment was adequate. Another 12 studies were unblinded but had adequate allocation concealment, classifying them as good quality studies. There was more than one study comparing co-trimoxazole with amoxycillin, oral amoxycillin with injectable penicillin/ampicillin and chloramphenicol with ampicillin/penicillin and studies were of good quality, suggesting the evidence for these comparisons was of high quality compared to other comparisons.In ambulatory settings, for treatment of World Health Organization (WHO) defined non-severe CAP, amoxycillin compared with co-trimoxazole had similar failure rates (odds ratio (OR) 1.18, 95% confidence interval (CI) 0.91 to 1.51) and cure rates (OR 1.03, 95% CI 0.56 to 1.89). Three studies involved 3952 children.In children with severe pneumonia without hypoxaemia, oral antibiotics (amoxycillin/co-trimoxazole) compared with injectable penicillin had similar failure rates (OR 0.84, 95% CI 0.56 to 1.24), hospitalisation rates (OR 1.13, 95

    Community-acquired pneumonia (CAP) is one of the most common infectious causes of morbidity and mortality in children <5 years of age. The aim of the study was to clarify the bacterial etiologic diagnosis in infants with CAP. A prospective, cross-sectional and descriptive study in patients 6 months to 2 years 11 months of age with CAP with poor outcome was conducted. Patients were admitted to the Pediatric Pneumology Service and underwent bronchoscopy with bronchoalveolar lavage (BAL), taking appropriate measures during the procedure to limit the risk of contamination. Aerobic bacteria isolated were Moraxella sp. 23%, Streptococcus mitis 23%, Streptococcus pneumoniae 18%, Haemophilus influenzae 12%, Streptococcus oralis 12%, and Streptococcus salivarius 12%. In contrast to other reports, we found Moraxella sp. to be a major bacterial pathogen, possibly because of improved detection with bronchoscopy plus BAL.

    Full Text Available Josef Yayan Department of Internal Medicine, Division of Pulmonary, Allergy and Sleep Medicine, Saarland University Medical Center, Homburg/Saar, Germany Background: Community-acquired pneumonia (CAP is an acute inflammation of the lungs, which is often caused by Streptococcus pneumoniae. CAP is the leading cause of death by infectious disease in industrialized countries. Therefore, an immediate and effective antibiotic therapy is of great importance for the nonfatal outcome of the disease. The literature contains increasing data about the development of resistance to antibiotics that are used for the treatment of CAP caused by S. pneumoniae; this article also examines the possible development of resistance to antibiotics in S. pneumoniae in recent years.Methods: Within the study period of 2004–2014, all hospital charts from patients with CAP caused by S. pneumoniae were collected from the Department of Internal Medicine, Saarland University Medical Center, Homburg/Saar, Germany. The tracheal secretions of S. pneumoniae in CAP patients were obtained by bronchoalveolar lavage; bronchial aspirates were obtained through flexible bronchoscopy and directly from sputum, and blood cultures were examined microbiologically for microorganisms.Results: From a total of 100 patients with CAP caused by S. pneumoniae, 23 (53.49% [34.78% female], 95% confidence interval, 38.58–68.4 patients with a mean age of 59.78±15.77 years met the inclusion criteria of this investigation. These patients were compared to a total of 20 (46.51% [35% female], 95% confidence interval, 31.6–61.42 patients with a mean age of 58.9±13.36 years with CAP who were infested with S. pneumoniae. In the latter group, the streptococcal antigen was detected in pulmonary aspirations by bronchoscopy or in urine using polymerase chain reaction and a rapid pneumococcal test. Penicillin G and vancomycin had a high rate of sensitivity on the antibiogram for S. pneumoniae, which was

    Full Text Available Lung ultrasonography has been advocated in diagnosing pediatric community-acquired pneumonia. However, its function in identifying necrotizing pneumonia, a complication, has not been explored. This study investigated the value of lung ultrasonography in diagnosing pediatric necrotizing pneumonia and its role in predicting clinical outcomes.We retrospectively reviewed 236 children with community-acquired pneumonia who were evaluated using lung ultrasonography within 2-3 days after admission. The ultrasonographic features assessed included lung perfusion, the presence of hypoechoic lesions, and the amount of pleural effusion. Chest computed tomography was also performed in 96 patients as clinically indicated. Detailed records of clinical information were obtained.Our results showed a high correlation between the degree of impaired perfusion in ultrasonography and the severity of necrosis in computed tomography (r = 0.704. The degree of impaired perfusion can favorably be used to predict massive necrosis in computed tomography (area under the receiver operating characteristic curve, 0.908. The characteristics of impaired perfusion and hypoechoic lesions in ultrasonography were associated with an increased risk of pneumatocele formation (odds ratio (OR, 10.11; 95% CI, 2.95-34.64 and the subsequent requirement for surgical lung resection (OR, 8.28; 95% CI, 1.86-36.93. Furthermore, a longer hospital stay would be expected if moderate-to-massive pleural effusion was observed in addition to impaired perfusion in ultrasonography (OR, 3.08; 95% CI, 1.15-8.29.Lung ultrasonography is favorably correlated with chest computed tomography in the diagnosis of necrotizing pneumonia, especially regarding massive necrosis of the lung. Because it is a simple and reliable imaging tool that is valuable in predicting clinical outcomes, we suggest that ultrasonography be applied as a surrogate for computed tomography for the early detection of severe necrotizing

    Full Text Available Objective: To assess the direct and indirect costs of diagnosing and treating community-acquired pneumonia (CAP, correlating those costs with CAP severity at diagnosis and identifying the major cost drivers. Methods: This was a prospective cost analysis study using bottom-up costing. Clinical severity and mortality risk were assessed with the pneumonia severity index (PSI and the mental Confusion-Urea-Respiratory rate-Blood pressure-age ≥ 65 years (CURB-65 scale, respectively. The sample comprised 95 inpatients hospitalized for newly diagnosed CAP. The analysis was run from a societal perspective with a time horizon of one year. Results: Expressed as mean ± standard deviation, in Euros, the direct and indirect medical costs per CAP patient were 696 ± 531 and 410 ± 283, respectively, the total per-patient cost therefore being 1,106 ± 657. The combined budget impact of our patient cohort, in Euros, was 105,087 (66,109 and 38,979 in direct and indirect costs, respectively. The major cost drivers, in descending order, were the opportunity cost (lost productivity; diagnosis and treatment of comorbidities; and administration of medications, oxygen, and blood derivatives. The CURB-65 and PSI scores both correlated with the indirect costs of CAP treatment. The PSI score correlated positively with the overall frequency of use of health care services. Neither score showed any clear relationship with the direct costs of CAP treatment. Conclusions: Clinical severity at admission appears to be unrelated to the costs of CAP treatment. This is mostly attributable to unwarranted hospital admission (or unnecessarily long hospital stays in cases of mild pneumonia, as well as to over-prescription of antibiotics. Authorities should strive to improve adherence to guidelines and promote cost-effective prescribing practices among physicians in southeastern Europe.

    Nonventilator hospital-acquired pneumonia (NV-HAP) is an underreported and unstudied disease, with potential for measurable outcomes, fiscal savings, and improvement in quality of life. The purpose of our study was to (a) identify the incidence of NV-HAP in a convenience sample of U.S. hospitals and (b) determine the effectiveness of reliably delivered basic oral nursing care in reducing NV-HAP. A descriptive, quasi-experimental study using retrospective comparative outcomes to determine (a) the incidence of NV-HAP and (b) the effectiveness of enhanced basic oral nursing care versus usual care to prevent NV-HAP after introduction of a basic oral nursing care initiative. We used the International Statistical Classification of Diseases and Related Problems (ICD-9) codes for pneumonia not present on admission and verified NV-HAP diagnosis using the U.S. Centers for Disease Control and Prevention diagnostic criteria. We completed an evidence-based gap analysis and designed a site-specific oral care initiative designed to reduce NV-HAP. The intervention process was guided by the Influencer Model (see Figure) and participatory action research. We found a substantial amount of unreported NV-HAP. After we initiated our oral care protocols, the rate of NV-HAP per 100 patient days decreased from 0.49 to 0.3 (38.8%). The overall number of cases of NV-HAP was reduced by 37% during the 12-month intervention period. The avoidance of NV-HAP cases resulted in an estimated 8 lives saved, $1.72 million cost avoided, and 500 extra hospital days averted. The extra cost for therapeutic oral care equipment was $117,600 during the 12-month intervention period. Cost savings resulting from avoided NV-HAP was $1.72 million. Return on investment for the organization was $1.6 million in avoided costs. NV-HAP should be elevated to the same level of concern, attention, and effort as prevention of ventilator-associated pneumonia in hospitals. Nursing needs to lead the way in the design and

    Previous reports suggest that community-acquired pneumonia (CAP) is associated with an enhanced risk of cardiovascular complications. However, a contemporary and comprehensive characterization of this association is lacking. In this multicenter study, 1182 patients hospitalized for CAP were prospectively followed for up to 30 days after their hospitalization for this infection. Study endpoints included myocardial infarction, new or worsening heart failure, atrial fibrillation, stroke, deep venous thrombosis, cardiovascular death, and total mortality. Three hundred eighty (32.2%) patients experienced intrahospital cardiovascular events (CVEs) including 281 (23.8%) with heart failure, 109 (9.2%) with atrial fibrillation, 89 (8%) with myocardial infarction, 11 (0.9%) with ischemic stroke, and 1 (0.1%) with deep venous thrombosis; 28 patients (2.4%) died for cardiovascular causes. Multivariable Cox regression analysis showed that intrahospital Pneumonia Severity Index (PSI) class (hazard ratio [HR], 2.45, P = .027; HR, 4.23, P < .001; HR, 5.96, P < .001, for classes III, IV, and V vs II, respectively), age (HR, 1.02, P = .001), and preexisting heart failure (HR, 1.85, P < .001) independently predicted CVEs. One hundred three (8.7%) patients died by day 30 postadmission. Thirty-day mortality was significantly higher in patients who developed CVEs compared with those who did not (17.6% vs 4.5%, P < .001). Multivariable Cox regression analysis showed that intrahospital CVEs (HR, 5.49, P < .001) independently predicted 30-day mortality (after adjustment for age, PSI score, and preexisting comorbid conditions). CVEs, mainly those confined to the heart, complicate the course of almost one-third of patients hospitalized for CAP. More importantly, the occurrence of CVEs is associated with a 5-fold increase in CAP-associated 30-day mortality. © The Author 2017.

    Full Text Available Introduction. Nonhospital pneumonia is the most common acute infectious infections disease of the lower respiratory tract. The incidence of the community-acquired pneumonia in Ukraine is 3 - 11 cases per 1,000 in adults per year and is the highest among the elderly and old patients. According to the foreign epidemiological studies, the incidence of nonhospital pneumonia in persons of young and middle-aged adults (> 18 years is 1 - 11,6 %; in the older age groups - 25 - 44 %. Mortality from nonhospital pneumonia without concomitant diseases is also the lowest (1-3 % in those young and middle age. In patients over 60 years of age, if there is a serious comorbidity and in cases of severe nonhospital pneumonia, this figure reaches 15-30 %. To improve treatment outcome in nonhospital pneumonia and cost optimization in recent years a number of international and national recommendations were proposed. This help doctor to choose the most rational strategy for the management of patients in a specific clinical situation. The aim of the study. Retrospective analysis of case histories of patients older than 60 years with nonhospital pneumonia treated in the therapeutic department during the period from September 2010 to May 2013. Assessment of the quality of medical care and the practice of the appointment systemic antibacterial therapy in accordance with modern standards and quality indicators. Material and methods. Were selected 66 case histories of patients with nonhospital pneumonia, men were 41 people (62.1%, and women - 25 (37,9%, the average age was 69,5 ± 8.1 years.

    Full Text Available Plasma YKL-40 level has been reported as playing a significant role in community-acquired pneumonia (CAP. However, the correlation between plasma level of YKL-40 and the severity of CAP has not been reported. This study identifies the relationship between plasma level changes of the YKL-40 gene in adult patients hospitalized with CAP. The ELISA was used to measure the plasma YKL-40 level from 61 adult CAP patients before and after antibiotic treatment and from 60 healthy controls. The plasma YKL-40 levels were significantly increased in patients with CAP compared to normal controls. Moreover, the plasma concentration of YKL-40 correlated with the severity of CAP based on the pneumonia severity index (PSI score (r = 0.630, p < 0.001, the CURB-65 (confusion, uremia, respiratory rate, BP, age 65 years score (r = 0.640, p < 0.001, the Acute Physiology And Chronic Health Evaluation II (APACHE II score (r = 0.539, p < 0.001 and length of hospital stay (r = 0.321, p = 0.011, respectively. In conclusion, plasma YKL-40 may play a role in the diagnosis and clinical assessment of CAP severity, which could potentially guide the development of treatment strategies.

    Full Text Available Systemic corticosteroids have anti-inflammatory effects, whereas macrolides also have immunomodulatory activity in addition to their primary antimicrobial actions. We aimed to evaluate the potential interaction effect between corticosteroids and macrolides on the systemic inflammatory response in patients with severe community-acquired pneumonia to determine if combining these two immunomodulating agents was harmful, or possibly beneficial.We performed a post-hoc exploratory analysis of a randomized clinical trial conducted in three tertiary hospitals in Spain. This trial included patients with severe community-acquired pneumonia with high inflammatory response (C-reactive protein [CRP] >15 mg/dL who were randomized to receive methylprednisolone 0.5 mg/kg/tpd or placebo. The choice of antibiotic treatment was at the physician's discretion. One hundred and six patients were classified into four groups according to antimicrobial therapy combination (β-lactam plus macrolide or β-lactam plus fluoroquinolone and corticosteroid arm (placebo or corticosteroids. The primary outcome was treatment failure (composite outcome of early treatment failure, or of late treatment failure, or of both early and late treatment failure.The methylprednisolone with β-lactam plus macrolide group had more elderly patients, with comorbidities, and higher pneumonia severity index (PSI risk class V, but a lower proportion of intensive care unit admission, compared to the other groups. We found non differences in treatment failure between groups (overall p = 0.374; however, a significant difference in late treatment failure was observed (4 patients in the placebo with β-lactam plus macrolide group (31% vs. 9 patients in the placebo with β-lactam plus fluoroquinolone group (24% vs. 0 patients in the methylprednisolone with β-lactam plus macrolide group (0% vs. 2 patients [5%] in the methylprednisolone with β-lactam plus fluoroquinolone group overall p = 0.009.

    The solid-phase immunoassay, semi-quantitative procalcitonin (PCT) test (B R A H M S PCT-Q) can be used to rapidly categorize PCT levels into four grades. However, the usefulness of this kit for determining the prognosis of adult patients with community-acquired pneumonia (CAP) is unclear. A prospective study was conducted in two Japanese hospitals to evaluate the usefulness of this PCT test in determining the prognosis of adult patients with CAP. The accuracy of the age, dehydration, respiratory failure, orientation disturbance, pressure (A-DROP) scale proposed by the Japanese Respiratory Society for prediction of mortality due to CAP was also investigated. Hospitalized CAP patients (n = 226) were enrolled in the study. Comprehensive examinations were performed to determine PCT and CRP concentrations, disease severity based on the A-DROP, pneumonia severity index (PSI) and confusion, urea, respiratory rate, blood pressure, age ≥65 (CURB-65) scales and the causative pathogens. The usefulness of the biomarkers and prognostic scales for predicting each outcome were then examined. Twenty of the 170 eligible patients died. PCT levels were strongly positively correlated with PSI (ρ = 0.56, P scale were found to be useful for predicting mortality in adult patients with CAP. © 2011 The Authors.

However, antibacterial agents used to treat common pathogens in CABP are marked by adverse drug events and increasing antimicrobial resistance. Solithromycin is a new ketolide antibiotic, based on the macrolide antibiotic structure, being studied for use in CABP. It has efficacy in vitro against the common causative pathogens in CABP including Streptococcus pneumoniae, Haemophilus influenzae, and atypical pathogens. In Phase II and Phase III clinical trials, it has been demonstrated efficacious as a single agent for treatment of CABP with an apparently milder adverse event profile than alternative agents.

    Full Text Available Although the Pseudomonas aeruginosa infection is well known and frequently found in hospitals and nursing care facilities, many cases are also reported outside these boundaries. In general, this pathogen infects debilitated patients either by comorbidities or by any form of immunodeficiency. In cases of respiratory infection, tobacco abuse seems to play an important role as a risk factor. In previously healthy patients, community-acquired pneumonia (CAP with P. aeruginosa as the etiological agent is extremely rare, and unlike the cases involving immunocompromised or hospitalized patients, the outcome is severe, and is fatal in up to 61.1% of cases. Aerosolized contaminated water or solutions are closely linked to the development of respiratory tract infection. In this setting, metalworking fluids used in factories may be implicated in CAP involving previously healthy people. The authors report the case of a middle-aged man who worked in a metalworking factory and presented a right upper lobar pneumonia with a rapid fatal outcome. P. aeruginosa was cultured from blood and tracheal aspirates. The autopsy findings confirmed a hemorrhagic necrotizing pneumonia with bacteria-invading vasculitis and thrombosis. A culture of the metalworking fluid of the factory was also positive for P. aeruginosa. The pulsed-field gel electrophoresis showed that both strains (blood culture and metalworking fluid were genetically indistinguishable. The authors highlight the occupational risk for the development of this P. aeruginosa-infection in healthy people.

    Community-acquired pneumonia is a common cause of hospitalization, and pneumococcal vaccinations are recommended for high-risk individuals. Although risk factors for pneumonia have been identified, there are currently no pneumonia hospitalization prediction models based on the risk profiles of healthy subjects. This study aimed to develop a predictive model for pneumonia hospitalization in adults to accurately identify high-risk individuals to facilitate the efficient prevention of pneumonia. We conducted a retrospective database analysis using health checkup data and health insurance claims data for residents of Kyoto prefecture, Japan, between April 2010 and March 2015. We chose adults who had undergone health checkups in the first year of the study period, and tracked pneumonia hospitalizations over the next 5 years. Subjects were randomly divided into training and test sets. The outcome measure was pneumonia hospitalization, and candidate predictors were obtained from the health checkup data. The prediction model was developed and internally validated using a LASSO logistic regression analysis. Lastly, we compared the new model with comparative models. The study sample comprised 54,907 people who had undergone health checkups. Among these, 921 were hospitalized for pneumonia during the study period. The c-statistic for the prediction model in the test set was 0.71 (95% confidence interval: 0.69-0.73). In contrast, a comparative model with only age and comorbidities as predictors had a lower c-statistic of 0.55 (95% confidence interval: 0.54-0.56). Our predictive model for pneumonia hospitalization performed better than comparative models, and may be useful for supporting the development of pneumonia prevention measures.

    Full Text Available Lung puncture is the best way to determine the etiology of pneumonia since it yields the highest rate of positive cultures. However, this procedure is difficult, especially for a study in the community. According to WHO, isolates to be tested for antimicrobial resistance in the community should be obtained from nasopharyngeal (NP swabs. Previous studies support the use of NP isolates to determine antimicrobial resistance patterns of isolates from children with pneumonia. The aim of our study was to know the bacterial patterns of the nasopharynx in underfive children with community acquired pneumonia and their antimicrobial resistance. The study was carried out in 4 Primary Health Clinics in Majalaya sub-district, Bandung, Indonesia. All underfives with cough or difficult breathing and classified as having non-severe pneumonia (WHO guidelines, were included in the study. Nasopharyngeal swabs (CDC/WHO Manual were obtained by the doctor, the swabs were placed in Amies transport medium and stored in a sterile jar before taken to the laboratory in the same day. All children were treated with co-trimoxazole. During the nine month study, 698 children with clinical signs of non-severe pneumonia were enrolled. About 25% of the nasopharyngeal specimens yielded bacterial isolates; the two most frequently found were S. pneumoniae and S. epidermidis. The antimicrobial resistance test to co-trimoxazole showed 48.2% S. pneumoniae strain had full resistance and 32.7% showed intermediate resistance to co-trimoxazole. This result is almost similar to other studies from Asian countries. It seems that H. influenzae is not a problem in the study area; however, further studies are needed.

    Carbapenems have an overall broad antibacterial spectrum and should be protected against from the acquisition of drug resistance. The clinical advantages of carbapenem in cases of pneumonia have not been certified and the need for antipseudomonal antimicrobial agents to treat healthcare-associated pneumonia (HCAP) remains controversial. We introduced an antimicrobial stewardship program for carbapenem and tazobactam/piperacillin use and investigated the effects of this program on the clinical outcomes of 591 pneumonia cases that did not require intensive care unit management, mechanical ventilation or treatment with vasopressor agents [221 patients with community-acquired pneumonia (CAP) and 370 patients with HCAP]. Compared with the pre-intervention period, age, comorbidities and the severity and etiology of pneumonia did not differ during the intervention period. Carbapenems were rarely used during the intervention period in cases of pneumonia (CAP: 12% vs. 1%, HCAP: 13% vs. 1%), while antipseudomonal beta-lactam use was reduced from 33% to 8% among cases with HCAP. This reduction in the rate of carbapenem administration did not have an impact on the prognosis in the cases of CAP, and the in-hospital mortality was lower among the patients with HCAP during the intervention period (15% vs. 5%, p = 0.013). The causes of death in the cases of HCAP were not directly related to pneumonia during the intervention period. The current study shows that carbapenem use can be avoided in cases of CAP or HCAP that are not in a critical condition. The frequent use of antipseudomonal beta-lactams does not improve the clinical outcomes of HCAP. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

  7. Using data-driven rules to predict mortality in severe community acquired pneumonia.

    Chuang Wu

    Full Text Available Prediction of patient-centered outcomes in hospitals is useful for performance benchmarking, resource allocation, and guidance regarding active treatment and withdrawal of care. Yet, their use by clinicians is limited by the complexity of available tools and amount of data required. We propose to use Disjunctive Normal Forms as a novel approach to predict hospital and 90-day mortality from instance-based patient data, comprising demographic, genetic, and physiologic information in a large cohort of patients admitted with severe community acquired pneumonia. We develop two algorithms to efficiently learn Disjunctive Normal Forms, which yield easy-to-interpret rules that explicitly map data to the outcome of interest. Disjunctive Normal Forms achieve higher prediction performance quality compared to a set of state-of-the-art machine learning models, and unveils insights unavailable with standard methods. Disjunctive Normal Forms constitute an intuitive set of prediction rules that could be easily implemented to predict outcomes and guide criteria-based clinical decision making and clinical trial execution, and thus of greater practical usefulness than currently available prediction tools. The Java implementation of the tool JavaDNF will be publicly available.

    Full Text Available The aim of this study was to investigate the IgM antibody positivities of atypical pneumonia agents in patients with community-acquired pneumonia (CAP, and to compare the results with controls. The serum samples which were collected from 87 adult patients and 21 healthy controls have been investigated by a commercial ELISA (Pneumobact ELISA IgM, Vircell, Spain in which four different atypical pneumonia agents were fixed onto a slide. In the patients group, IgM positivity rates for the agents were as follows, respectively; 2.3% for Legionella pneumophila, 56.3% Chlamydia pneumoniae, 33.3% for Mycoplasma pneumoniae, 9.2% for Coxiella burnetii. The rates of IgM positivities in the control group varied 7% for all of the agents except M. Pneumoniae and C. Pneumoniae and 2 of these controls were positive for L. Pneumophila IgM, one was positive for C. Burnetii IgM. According to the statistical evaluation, there were significant differences for IgM seropositivities to Mycoplasma pneumoniae and Chlamydia Pneumoniae,between the patient and the control groups (p0.05. We showed that the seropositivity rate of atypical agents in patients with CAP was significantly higher when compared to healthy control group. This result suggests us, atypical agents might be responsible in CAP patients in a great amount. Furthermore, our study also suggests that clinical and radiological findings are not useful for discriminating atypical from typical pneumonia. [TAF Prev Med Bull 2007; 6(4.000: 279-284

    Objective: To understand the current status of diagnosis and treatment of community-acquired pneumonia (CAP) among doctors in various hospitals across Shanghai, for the purpose of promoting the 2016 clinical practice guidelines for adult CAP of China. Methods: A questionnaire was designed to address the common questions in CAP management. The responses were collected via WeChat and the data were analyzed. Results: A total of 1 254 valid questionnaires were received, 46.1% from tertiary , 26.4% from secondary and 27.5% from primary care hospitals. Of these valid respondents, 31.4% were respiratory physicians and 68.6% from non-respiratory physicians. When diagnosing CAP, 78.1% of the doctors would use chest CT in more than 50% of the patients. Regarding the tools for evaluating the severity of CAP, 60.3% of the respondents would prefer CURB-65. "Respiratory failure requiring mechanical ventilation and septic shock" were the most common criteria for admission to ICU. Blood culture was not widely used in severe CAP regardless of the level of hospitals ( P >0.05). The results of this survey showed that the top 5 pathogenic microorganisms of CAP were Streptococcus pneumoniae, Mycoplasma pneumoniae, Klebsiella pneumoniae, Haemophilus influenza and Chlamydia pneumoniae. For non-severe CAP patients, all the doctors tended to select monotherapy. The most frequently used antimicrobial regimen for severe CAP was third- or fourth-generation cephalosporin monotherapy. As for combination therapy, the most frequently used regimen in tertiary hospitals was "carbapenem plus vancomycin" , while in primary and secondary hospitals it was "β-lactams plus macrolides" . More doctors from primary hospitals and non-respiratory medicine would consider "complete resolution of pulmonary opacity" as the indication to discontinue antimicrobial therapy or to discharge patients, and "prolonged high fever" , "large area consolidation" , "multiple lobe-segment involvement " as the indication for

    Full Text Available Abstract Background The 23-valent polysaccharide pneumococcal vaccine (PPV-23 is recommended for elderly and high-risk people, although its effectiveness is controversial. Some studies have reported an increasing risk of acute vascular events among patients with pneumonia, and a recent case-control study has reported a reduction in the risk of myocardial infarction among patients vaccinated with PPV-23. Given that animal experiments have shown that pneumococcal vaccination reduces the extent of atherosclerotic lesions, it has been hypothesized that PPV-23 could protect against acute vascular events by an indirect effect preventing pneumonia or by a direct effect on oxidized low-density lipoproteins. The main objective of this study is to evaluate the clinical effectiveness of PPV-23 in reducing the risk of pneumonia and acute vascular events (related or nonrelated with prior pneumonia in the general population over 60 years. Methods/Design Cohort study including 27,000 individuals 60 years or older assigned to nine Primary Care Centers in the region of Tarragona, Spain. According to the reception of PPV-23 before the start of the study, the study population will be divided into vaccinated and nonvaccinated groups, which will be followed during a consecutive 30-month period. Primary Care and Hospitals discharge databases will initially be used to identify study events (community-acquired pneumonia, hospitalisation for acute myocardial infarction and stroke, but all cases will be further validated by checking clinical records. Multivariable Cox regression analyses estimating hazard ratios (adjusted for age, sex and comorbidities will be used to estimate vaccine effectiveness. Discussion The results of the study will contribute to clarify the controversial effect of the PPV-23 in preventing community-acquired pneumonia and they will be critical in determining the posible role of pneumococcal vaccination in cardiovascular prevention.

    Full Text Available In an era when Haemophilus influenzae type b (Hib conjugate vaccine is widely used, the incidence of Hib as a cause of community-acquired pneumonia (CAP has dramatically declined. Non-typeable H. influenzae (NTHi strains and, occasionally, other encapsulated serotypes of H. influenzae are now the cause of the majority of invasive H. influenzae infections, including bacteraemic CAP. NTHi have long been recognised as an important cause of lower respiratory tract infection, including pneumonia, in adults, especially those with underlying diseases. The role of NTHi as a cause of non-bacteraemic CAP in children is less clear. In this review the evidence for the role of NTHi and capsulated strains of H. influenzae will be examined.

    Full Text Available Question: Among people who are hospitalised for community-acquired pneumonia, does an inpatient exercise-based rehabilitation program improve functional outcomes, symptoms, quality of life and length of hospital stay more than a respiratory physiotherapy regimen? Design: Randomised trial with concealed allocation, intention-to-treat analysis and blinding of some outcomes. Participants: Forty-nine adults hospitalised for community-acquired pneumonia. Intervention: The experimental group (n = 32 underwent a physical training program that included warm-up, stretching, peripheral muscle strength training and walking at a controlled speed for 15 minutes. The control group (n = 17 underwent a respiratory physiotherapy regimen that included percussion, vibrocompression, respiratory exercises and free walking. The intervention regimens lasted 8 days. Outcome measures: The primary outcome was the Glittre Activities of Daily Living test, which assesses the time taken to complete a series of functional tasks (eg, rising from a chair, walking, stairs, lifting and bending. Secondary outcomes were distance walked in the incremental shuttle walk test, peripheral muscle strength, quality of life, dyspnoea, lung function, C-reactive protein and length of hospital stay. Measures were taken 1 day before and 1 day after the intervention period. Results: There was greater improvement in the experimental group than in the control group on the Glittre Activities of Daily Living test (mean between-group difference 39 seconds, 95% CI 20 to 59 and the incremental shuttle walk test (mean between-group difference 130 m, 95% CI 77 to 182. There were also significantly greater improvements in quality of life, dyspnoea and peripheral muscle strength in the experimental group than in the control group. There were no between-group differences in lung function, C-reactive protein or length of hospital stay. Conclusion: The improvement in functional outcomes after an

    Stenotrophomonas maltophilia (S. maltophilia) is a rare, but globally emerging gram-negative multiple-drug-resistant organism usually found in a nosocomial setting in immunocompromised patients. To our best knowledge, computed tomography (CT) features of community-acquired S. maltophilia pneumonia have not been previously reported in an immunocompetent patient. Herein, we presented the CT findings of a previous healthy 56-year-old male with S. maltophilia pneumonia.

    This study aims to determine the association of commonly used biochemical markers, such as albumin and C-reactive protein (CRP), with mortality and the prognostic performance of these markers combined with the pneumonia severity index (PSI) for mortality and adverse outcomes in patients with community-acquired pneumonia (CAP). The data were gathered prospectively for patients hospitalized with CAP via the emergency department. Laboratory values, including CRP and albumin, clinical variables, and the PSI were measured. Primary outcomes were 28-day mortality and survival times. Secondary outcome was admission to the intensive care unit, vasopressor use, or the need for mechanical ventilation during the hospital stay. A total of 424 patients were included. The 28-day mortality was 13.7%. C-reactive protein and albumin were significantly different between survivors and nonsurvivors. In logistic regression analysis, CRP and albumin were independently associated with 28-day mortality (P scale. The Cox proportional hazards analysis showed that high serum albumin (≥3.3 mg/dL) had a hazard ratio of 0.5 (95% confidence interval, 0.3-0.9), and high CRP (≥14.3 mg/dL) had a hazard ratio of 2.0 (95% confidence interval, 1.1-3.4). For predicting secondary outcome, adding albumin to PSI increased areas under the curve significantly, but CRP did not. Albumin and CRP were associated with 28-day mortality in hospitalized patients with CAP, and these markers increased prognostic performance when combined with the PSI scale. Crown Copyright © 2011.

    Full Text Available We hypothesized that obstructive sleep apnea (OSA can predispose individuals to lower airway infections and community-acquired pneumonia (CAP due to upper airway microaspiration. This study evaluated the association between OSA and CAP.We performed a case-control study that included 82 patients with CAP and 41 patients with other infections (control group. The controls were matched according to age, sex and body mass index (BMI. A respiratory polygraph (RP was performed upon admission for patients in both groups. The severity of pneumonia was assessed according to the Pneumonia Severity Index (PSI. The associations between CAP and the Epworth Sleepiness Scale (ESS, OSA, OSA severity and other sleep-related variables were evaluated using logistic regression models. The associations between OSA, OSA severity with CAP severity were evaluated with linear regression models and non-parametric tests.No significant differences were found between CAP and control patients regarding anthropometric variables, toxic habits and risk factors for CAP. Patients with OSA, defined as individuals with an Apnea-Hypopnea Index (AHI ≥10, showed an increased risk of CAP (OR = 2·86, 95%CI 1·29-6·44, p = 0·01. Patients with severe OSA (AHI≥30 also had a higher risk of CAP (OR = 3·18, 95%CI 1·11-11·56, p = 0·047. In addition, OSA severity, defined according to the AHI quartile, was also significantly associated with CAP (p = 0·007. Furthermore, OSA was significantly associated with CAP severity (p = 0·0002, and OSA severity was also associated with CAP severity (p = 0·0006.OSA and OSA severity are associated with CAP when compared to patients admitted to the hospital for non-respiratory infections. In addition, OSA and OSA severity are associated with CAP severity. These results support the potential role of OSA in the pathogenesis of CAP and could have clinical implications. This link between OSA and infection risk should be explored to investigate the

    Full Text Available Pathogens in nasopharynx is a significant risk factor of pneumonia. According to WHO, isolates to be tested for antimicrobial resistance in the community should be obtained from nasopharyngeal (NP swabs. The aim of this study is to know the bacterial patterns of the nasopharynx and cotrimoxazole resistance in under five-year old children with community acquired pneumonia. The study was carried out in 4 primary health clinic (Puskesmas in Majalaya sub-district, Bandung, West Java, Indonesia. All underfive children with cough and/or difficult breathing and classified as having non-severe pneumonia (WHO guidelines were placed in Amies transport medium and stored in a sterile jar, before taken to the laboratory for further examination, in the same day. During this nine month study, 698 children with clinical signs of non-severe pneumonia were enrolled. About 25.4% (177/698 of the nasopharyngeal specimens yielded bacterial isolates; i.e. 120 (67.8% were positive for S pneumoniae, 21 for S epidermidis and alpha streptococcus, 6 for Hafnia alvei, 5 for S aureus, 2 for B catarrhalis, and 1(0.6% for H influenza and Klebsiella, respectively. The antimicrobial resistance test to cotrimoxazole showed that 48.2% of S pneumoniae strain had full resistance and 32.7% showed intermediate resistance to cotrimoxazole. This result is almost similar to the other studies from Asian countries. It seems that H influenza is not a problem in the study area, however, a further study is needed.

    Community-acquired pneumonia (CAP) continues to be associated with significant mortality and morbidity. As with other infectious diseases, in recent years there has been a marked increase in resistance to the antibiotics commonly used against the pathogens that cause CAP. Antimicrobial stewardship denotes coordinated interventions to improve and measure the appropriate use of antibiotics by encouraging the selection of optimal drug regimens. Areas covered: Several elements can be applied to antibiotic stewardship strategies for CAP in order to maintain or improve patient outcomes. In this regard, antibiotic de-escalation, duration of antibiotic treatment, adherence to CAP guidelines recommendations about empirical treatment, and switching from intravenous to oral antibiotic therapy may each be relevant in this context. Antimicrobial stewardship strategies, such as prospective audit with intervention and feedback, clinical pathways, and dedicated multidisciplinary teams, that have included some of these elements have demonstrated improvements in antimicrobial use for CAP without negatively affecting clinical outcomes. Expert commentary: Although there are a limited number of randomized clinical studies addressing antimicrobial stewardship strategies in CAP, there is evidence that antibiotic stewardship initiatives can be securely applied, providing benefits to both healthcare systems and patients.

    Antibiotic treatment before microbiological test significant reduces the positive rate of culture methods of Streptococcus pneumoniae. The Binax NOW S. pneumoniae immunochromatographic test (ICT) has become a more commonly used procedure to diagnose S. pneumoniae from community-acquired pneumonia in adults. However, performance of this test after empirical antimicrobial therapy is uncertain. Therefore, in this prospective study, we evaluate the impact of antimicrobial therapy on sensitivity of ICT test in 487 hospitalized adult patients. The results showed that 192 (39.4 %) and 295 (60.6 %) specimens were collected before (Group 1) or after antibiotic treatment (Group 2), respectively. S. pneumoniae was detected by ICT in 21 (10.9 %) patients in the Group 1 and 39 (13.2 %) in the Group 2 and their positive rates were not different (P > 0.05). However, The positive rate of blood and pleural fluid was declined from 5.7 to 2.7 % and sputum, from 9.9 to 4.7 % after the antibiotic treatment, respectively. This study confirmed that the ICT urinary antigen test remained to have a high sensitivity for diagnosis of pneumococcal infection after empiric antibiotic treatment was started. The ICT urinary antigen test would have a potential to guide the right choice of therapy for pneumonia in adults earlier.

    Full Text Available Community-acquired pneumonia (CAP can occur at any time of life, but its incidence and risk of death are linked to increasing age. CAP in the elderly is a major health problem associated with high rates of readmission, morbidity, and mortality. Since the clinical presentation of pneumonia in the elderly may be atypical, clinicians should suspect pneumonia in older patients presenting symptoms such as falls and altered mental status, fatigue, lethargy, delirium, anorexia, in order to avoid the complications associated with delayed diagnosis and therapy. Streptococcus pneumoniae remains the most frequently reported pathogen in this population. However, particular attention should be paid to patients with risk factors for multidrug resistant pathogens, because a large proportion of elderly persons present multimorbidity. Vaccination is one of the most important preventive approaches for CAP in the elderly. In addition, lifestyle-tailored interventions for different modifiable risk factors will help to reduce the risk of pneumonia in elderly persons. Surveillance of etiological pathogens may improve vaccination policies in this population.

    Community-acquired pneumonia (CAP) and oropharyngeal dysphagia (OD) are prevalent conditions in the elderly. The aim of this study was to explore the relationship between CAP, OD, and frailty in patients admitted to a department of respiratory medicine at a regional hospital. The outcome was mortality during hospitalization and within 30 days of discharge and rehospitalization within 30 days of discharge. A total of 154 consecutive patients (54.5% male, mean age 77.4 years (SD 11.51)) hospitalized because of CAP from September 1, 2013 to March 31, 2014 at North Denmark Regional Hospital were included in this study. The volume-viscosity swallow test was conducted for each patient. A total of 34.42% patients presented with OD. Patients with OD and CAP presented significant differences in age, CURB-65, and dementia compared with those of patients with CAP alone. The majority lived in nursing homes, had a lower body mass index, Barthel 20 score, and handgrip strength, and had poor oral health compared with patients with CAP only. Patients with OD presented an increased length of stay in hospital (P < 0.001), intra-hospital mortality (P < 0.001), and 30-day mortality rate (P < 0.001) compared with those of patients with CAP only. Their rate of rehospitalization 0-30 days after discharge was also increased (P < 0.001) compared with that of patients with CAP only. Thus, OD is related to frailty and poor outcome.

    Full Text Available Currently, a marker which could be used both to assess the severity of community acquired pneumonia (CAP and determine the risk of complications is being searched. According to some authors, Neutrophil-to-Lymphocyte Ratio (NLR could be such a marker. Therefore, the aim of our research was to determine the diagnostic significance of NLR in patients with CAP and to establish the relationship of NLR with other clinical and laboratory parameters. We conducted a retrospective analysis of 171 case histories of patients with CAP of 3 and 4 clinical groups, with the calculation of NLR (according to the common blood count. In the course of the work, it was found that NLR reflects a balance between the response of neutrophils and lymphocytes and this parameter is associated with the severity of systemic inflammation in patients with CAP. NLR has good diagnostic value in determining the mortality risk in patients with CAP, specially an increase in the level of NLR (more than 10 is associated with a high risk of life-threatening complications.

    In a previous phase 3 study, the cure rates that occurred in patients with hospital-acquired pneumonia treated with tigecycline at the approved dose were lower than those seen with patients treated with imipenem and cilastatin (imipenem/cilastatin). We hypothesized that a higher dose of tigecycline is necessary in patients with hospital-acquired pneumonia. This phase 2 study compared the safety and efficacy of two higher doses of tigecycline with imipenem/cilastatin in subjects with hospital-acquired pneumonia. Subjects with hospital-acquired pneumonia were randomized to receive one of two doses of tigecycline (150 mg followed by 75 mg every 12 h or 200 mg followed by 100 mg every 12 h) or 1 g of imipenem/cilastatin every 8 h. Empirical adjunctive therapy was administered for initial coverage of methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa infection, depending on the randomization regimen. Clinical response, defined as cure, failure of treatment, or indeterminate outcome, was assessed 10 to 21 days after the last day of therapy. In the clinically evaluable population, clinical cure with tigecycline 100 mg (17/20, 85.0%) was numerically higher than with tigecycline 75 mg (16/23, 69.6%) and imipenem/cilastatin (18/24, 75.0%). No new safety signals with the high-dose tigecycline were identified. A numerically higher clinical response was observed with the 100-mg dose of tigecycline. This supports our hypothesis that a higher area under the concentration-time curve over 24 h in the steady state divided by the MIC (AUC/MIC ratio) may be necessary to achieve clinical cure in patients with hospital-acquired pneumonia. Further studies are necessary. (The ClinicalTrials.gov identifier for this clinical trial is NCT00707239.).

    Full Text Available Abstract Background Pneumonia is one of the leading hospital-acquired infections worldwide and has an important impact. Although preventive measures for ventilator-associated pneumonia (VAP are well known, less is known about appropriate measures for prevention of hospital-acquired pneumonia (HAP. Aim The purpose of this narrative review is to provide an overview of the current standards for preventing HAP in non-ventilated adult patients. Methods A search of the literature up to May 2015 was conducted using Medline for guidelines published by national professional societies or professional medical associations. In addition, a comprehensive search for the following preventive measures was performed: hand hygiene, oral care, bed position, mobilization, diagnosis and treatment of dysphagia, aspiration prevention, viral infections and stress bleeding prophylaxis. Findings Regarding international guidelines, several measures were recommended for VAP, whilst no specific recommendations for HAP prevention in non-ventilated patients are available. There is reasonable evidence available that oral care is associated with a reduction in HAP. Early mobilization interventions, swift diagnosis and treatment of dysphagia, and multimodal programmes for the prevention of nosocomial influenza cross-infection, have a positive impact on HAP reduction. The impact of bed position and stress bleeding prophylaxis remains uncertain. Systematic antibiotic prophylaxis for HAP prevention should be avoided. Conclusion Scant literature and little guidance is available for the prevention of HAP among non-ventilated adult patients. In addition, the criteria used for the diagnosis of HAP and the populations targeted in the studies selected are heterogeneous. Oral care was the most studied measure and was commonly associated with a decrease in HAP rate, although a broad range of interventions are proposed.

A prospective, observational, descriptive, comparative study carried out from 1st January 2008 to 1st August 2009 in two phases: before and after the implementation of the "Management of CAP in ED" SEMES-SEPAR (Spanish Society of Emergency Medicine - Spanish Society of Pneumology and Thoracic Surgery) clinical practice guidelines from 2008. Two hundred adult patients treated in the ED with a diagnosis of CAP were included in the study, both in the pre-intervention and post-intervention groups. The application of the guidelines increased the administration of early and appropriate antibiotic therapy (Pimplementation of the SEMES-SEPAR 2008 guidelines, along with the use of PSI and biomarkers, significantly improved the entire treatment process of CAP. This benefitted both patients and the system by reducing mortality and improving the results of other patient management factors. Copyright © 2012 SEPAR. Published by Elsevier España, S.L.

    Community acquired pneumonia (CAP) is an important cause of morbidity and mortality around the world, with high treatment costs due to hospitalization and complications (adverse events due to medications, antibiotic resistance, healthcare associated infections, etc.). It has been proposed administration of short courses and early switch of intravenous administration to oral therapy to avoid costs and complications. There are recommendations about these topics in national and intemational guidelines, based on clinical trials which do not demónstrate diffe-rences in mortality and complications when there is an early change from intravenous administration to the oral route. There are no statistically significant differences in safety and resolution of the disease when short and long treatment schemes were compared. In this review we present the most important guidelines and clinical studies, taking into account the pharmacological differences between different medications. It is considered that early switch from intravenous to oral administration route and use of short cycles in CAP is safe and brings benefits to patients and institutions.

    Abstract Community-acquired pneumonia (CAP) is a common but potentially life-threatening condition, but limited information exists on the effectiveness of fluoroquinolones compared to β-lactams in outpatient settings. We aimed to compare the effectiveness and outcomes of penicillins versus respiratory fluoroquinolones for CAP at outpatient clinics. This was a claim-based retrospective cohort study. Patients aged 20 years or older with at least 1 new pneumonia treatment episode were included, and the index penicillin or respiratory fluoroquinolone therapies for a pneumonia episode were at least 5 days in duration. The 2 groups were matched by propensity scores. Cox proportional hazard models were used to compare the rates of hospitalizations/emergence service visits and 30-day mortality. A logistic model was used to compare the likelihood of treatment failure between the 2 groups. After propensity score matching, 2622 matched pairs were included in the final model. The likelihood of treatment failure of fluoroquinolone-based therapy was lower than that of penicillin-based therapy (adjusted odds ratio [AOR], 0.88; 95% confidence interval [95%CI], 0.77–0.99), but no differences were found in hospitalization/emergence service (ES) visits (adjusted hazard ratio [HR], 1.27; 95% CI, 0.92–1.74) and 30-day mortality (adjusted HR, 0.69; 95% CI, 0.30–1.62) between the 2 groups. The likelihood of treatment failure of fluoroquinolone-based therapy was lower than that of penicillin-based therapy for CAP on an outpatient clinic basis. However, this effect may be marginal. Further investigation into the comparative effectiveness of these 2 treatment options is warranted. PMID:26871827

    Background Community acquired pneumonia (CAP) is a major cause of morbidity and mortality. We recently demonstrated that among young patients (patient characteristic, 90-day mortality and complicated hospitalization. Results The cohort included 3815 patients. In univariate analysis, patients with co-morbid conditions tended to have a complicated course of CAP. In multivariate regression analysis, variables associated with an increased risk of 90-day mortality included age > 70 years, high Charlson comorbidity index (>2), Hb 30 mg/dl, systolic blood pressure 15%. Variables associated with complicated hospitalization included high Charlson comorbidity index, BUN > 30 mg/dl, hemoglobin 124 bpm, systolic blood pressure < 90 mmHg and elevated RDW. Mortality rate and complicated hospitalization were significantly higher among patients with increased RDW regardless of the white blood cell count or hemoglobin levels. Conclusions Elevated RDW levels on admission are associated with significant higher rates of mortality and severe morbidity in adult patients with CAP. RDW as a prognostic marker was unrelated with hemoglobin levels, WBC count, age or Charlson score. PMID:24597687

    The semi-quantitative serum procalcitonin test (Brahms PCT-Q) is available conveniently in clinical practice. However, there are few data on the relationship between results for this semi-quantitative procalcitonin test and clinical outcomes of community-acquired pneumonia (CAP). We investigated the usefulness of this procalcitonin test for predicting the clinical outcomes of CAP in comparison with severity scoring systems and the blood urea nitrogen/serum albumin (B/A) ratio, which has been reported to be a simple but reliable prognostic indicator in our prior CAP study. This retrospective study included data from subjects who were hospitalized for CAP from August 2010 through October 2012 and who were administered the semi-quantitative serum procalcitonin test on admission. The demographic characteristics; laboratory biomarkers; microbiological test results; Pneumonia Severity Index scores; confusion, urea nitrogen, breathing frequency, blood pressure, ≥ 65 years of age (CURB-65) scale scores; and age, dehydration, respiratory failure, orientation disturbance, pressure (A-DROP) scale scores on hospital admission were retrieved from their medical charts. The outcomes were mortality within 28 days of hospital admission and the need for intensive care. Of the 213 subjects with CAP who were enrolled in the study, 20 died within 28 days of hospital admission, and 32 required intensive care. Mortality did not differ significantly among subjects with different semi-quantitative serum procalcitonin levels; however, subjects with serum procalcitonin levels ≥ 10.0 ng/mL were more likely to require intensive care than those with lower levels (P pneumonia.

    Bacteremia is an important cause of morbimortality. This study describes the episodes of community-acquired bacteremia in adult patients registered at our hospital. Between January 2005, and December 2009, 271 episodes were studied. The diagnostic yield of blood cultures was 13.5 %. A total of 52 % of patients were male and 48 % female. The mean age was 60. The most frequent comorbidities were: diabetes (21 %), neoplasia (18 %), cardiopathy (11 %), and HIV infection (8 %). The focus was- respiratory (21 %), urinary (15 %), cutaneous (9 %), and others (13 %). Gram-positive bacteria prevailed (51.4%). The most frequent microorganisms were Escherichia coli (25 %), Streptococcus pneumoniae (22.9 %), and Staphylococcus aureus (12.3 %). Bacteremia was polymicrobial in 7 % of the cases. Thirty three percent of E. coli isolates were resistant to ciprofloxacin and 6 % to ceftazidime. Fourteen percent of S. aureus strains were resistant to oxacillin whereas only 7 % of S. pneumoniae expressed high resistance to penicillin with MICs = 2 ug/ml, according to meningitis breakpoints.

    As surveillance of hospital-acquired pneumonia (HAP) is very resource intensive, alternatives for HAP surveillance are needed urgently. This study compared HAP rates according to routine discharge diagnostic codes of the International Classification of Diseases, 10 th Revision (ICD-10; ICD-HAP) with HAP rates according to the validated surveillance definitions of the Hospitals in Europe Link for Infection Control through Surveillance (HELICS/IPSE; HELICS-HAP) by manual retrospective re-evaluation of patient records. The positive predictive value of ICD-HAP for HELICS-HAP was 0.35, and sensitivity was 0.59. Therefore, the currently available ICD-10-based routine discharge data do not allow reliable identification of patients with HAP. Copyright © 2018 The Healthcare Infection Society.

    The assessment of level severity ofCommunity-Acquired Pneumonia (CAP) patient at the early admission to the hospital is critical because it will determine the severity of the disease and the subsequent management of the plan. Albumin can be used as a biomarker to assess the severity of CAP. To identify the correlation between albumin level at early admission in hospital with 30-day mortality in patients with CAP. It was a cohort study. We had examined of 50 CAP subject with theCURB-65 score (Confusion, Urea, Respiratory rate, Blood pressure, Age >65years), albumin, sputum culture at the early admission at Emergency Room (ER). Then, albumin levels associated with 30-day mortality was assessed using Chi-Square test. Analysis with chi-square test found a significant correlation between albumin level with 30-day mortality (p=0.001) and Relative Risk was 2.376 (95% CI 1.515-3.723). It means that patients with CAP who has severe hypoalbuminemia have a higher risk ofdying in 30 days with 2,376 times more significant than patients with mild to moderate hypoalbuminemia. In conclusion, albumin levels at early admission in the hospital correlate with 30-day mortality in CAP patients.

    The 2005 American Thoracic Society/Infectious Diseases Society of America (ATS/IDSA) guidelines for hospital-acquired pneumonia (HAP), ventilator-associated pneumonia (VAP), and health care-associated pneumonia (HCAP) stress the importance of initiating prompt appropriate empiric antibiotic therapy. This study's purpose was to determine the percentage of patients with HAP, VAP, and HCAP who received guideline-based empiric antibiotic therapy and to determine the average time to receipt of an appropriate empiric regimen. A retrospective chart review of adults with HAP, VAP, or HCAP was conducted at a community hospital in suburban Birmingham, Alabama. The hospital's electronic medical record system utilized International Classification of Diseases, Ninth Revision (ICD-9) codes to identify patients diagnosed with pneumonia. The percentage of patients who received guideline-based empiric antibiotic therapy was calculated. The mean time from suspected diagnosis of pneumonia to initial administration of the final antibiotic within the empiric regimen was calculated for patients who received guideline-based therapy. Ninety-three patients met the inclusion criteria. The overall guideline adherence rate for empiric antibiotic therapy was 31.2%. The mean time to guideline-based therapy in hours:minutes was 7:47 for HAP and 28:16 for HCAP. For HAP and HCAP combined, the mean time to appropriate therapy was 21:55. Guideline adherence rates were lower and time to appropriate empiric therapy was greater for patients with HCAP compared to patients with HAP. © The Author(s) 2015.

    Community-acquired pneumonia (CAP) is the leading infectious disease requiring hospitalization in the western world. Genetic variability affecting the host response to infection may play a role in susceptibility and outcome in patients with CAP. Mannose-binding lectin (MBL) and l-ficolin (l-FCN) are two important activators of the complement system and they can enhance phagocytosis by opsonization. In a prospective cohort of 505 Dutch patients with CAP and 227 control participants we studied whether polymorphisms in the MBL (MBL2) and FCN (FCN2) genes influenced susceptibility and outcome. No difference in frequency of these genotypes was found between patients with CAP in general and controls. However, the +6424G>T single nucleotide polymorphism (SNP) in FCN2 was more common in patients with a Coxiella burnetii pneumonia (P = 0·014). Moreover, the haplotypes coding for the highest MBL serum levels (YA/YA and YA/XA) predisposed to atypical pneumonia (C. burnetii, Legionella or Chlamydia species or Mycoplasma pneumoniae) compared with controls (P = 0·016). Furthermore, patients with these haplotypes were more often bacteraemic (P = 0·019). It can therefore be concluded that MBL2 and FCN2 polymorphisms are not major risk factors for CAP in general, but that the +6424G>T SNP in the FCN2 gene predisposes to C. burnetii pneumonia. In addition, patients with genotypes corresponding with high serum MBL levels are at risk for atypical pneumonia, possibly caused by enhanced phagocytosis, thereby promoting cell entry of these intracellular bacteria. © 2016 The Authors.

    There are three Anglo-Saxon guidelines for the management of patients with a community-acquired pneumonia: an American, a British and a Canadian one. The guidelines correspond fairly well. There is a subdivision into categories according to whether the patients are treated at home (formerly healthy patients younger than 60 years versus patients with pre-existent disease or aged 60 years and more) or in the hospital (patients not needing intensive care versus those who do need it). For each category the most common causative micro-organisms are listed together with recommended antibiotic treatment. The Canadian guidelines have nursing home patients as a separate category because of slightly different causative organisms due to frequent microaspiration. The guidelines are applicable to the situation in the Netherlands, with a few exceptions: antibiotic resistance is not a major problem in the Netherlands (as yet), and contrary to what the guidelines state an agent with activity against Pseudomonas aeruginosa is not necessary; the same agents as in category III can be prescribed in these patients. A macrolide or azalide antibiotic is advisable for intensive care patients in view of the possibility of infection with Legionella pneumophila or Mycoplasma pneumoniae.

    Obtaining precise etiological information regarding causative bacteria is important for the proper use of antimicrobials in hospital-acquired pneumonia (HAP), which is associated with a high rate of mortality. The aim of this study was to comparatively investigate the bacterial diversity in bronchoalveolar lavage fluid (BALF) in Japanese patients with HAP by the clone library method using the 16S rRNA gene. This study included Japanese patients with HAP who were treated at our hospital and referring hospitals. BALF specimens were obtained from pneumonia lesions identified on chest radiographs and/or computed tomography. Sputum specimens were also evaluated in patients with sputum production. Sixty-eight patients were ultimately enrolled. BALF cultivation revealed bacterial positivity in 53 of 68 (77.9%) patients, and Staphylococcus aureus (30.9%) was the most frequently isolated, followed by Pseudomonas aeruginosa (16.2%), and Escherichia coli (10.3%). In contrast, the clone library analysis identified the presence of some bacterial phenotype in 65 of 68 (95.6%) patients, and streptococci (16.2%), Corynebacterium species (11.8%), anaerobes (10.3%) were frequently detected as the predominant phylotypes. Both methods tended to detect S. aureus, Klebsiella pneumoniae, and E. coli in patients with late-onset pneumonia. In addition, the cases that phylotypes of S. aureus and P. aeruginosa were found to account for > 5% of the bacterial flora of each case were 42.9% and 72.7%, respectively. These results indicate that attention should be paid to the roles of gram-positive bacilli such as streptococci, Corynebacterium species and anaerobes, in addition to Gram-negative bacilli, in the pathogenesis of HAP.

    The primary driver of health care costs for patients with community-acquired pneumonia (CAP) is the hospital length of stay (LOS). Unfortunately, hospital LOS comparisons are difficult to make from phase III CAP trials because of their structured designs and prespecified treatment durations. However, an opportunity still exists to draw inferences about potential LOS differences between treatments through the use of surrogates for hospital discharge. The intent of this study was to quantify the time to a clinical response, a proxy for the time to discharge readiness, among hospitalized CAP patients who received either ceftaroline or ceftriaxone in two phase III CAP FOCUS clinical trials. On the basis of the Infectious Diseases Society of America and American Thoracic Society CAP management guidelines and recent FDA guidance documents for community-acquired bacterial pneumonia, a post hoc adjudication algorithm was constructed a priori to compare the time to a clinical response, a proxy for the time to discharge readiness, between patients who received ceftaroline or ceftriaxone. Overall, 1,116 patients (ceftaroline, n=562; ceftriaxone, n=554) from the pooled FOCUS trials met the selection criteria for this analysis. Kaplan-Meier analyses showed that ceftaroline was associated with a shorter time, measured in days, to meeting the clinical response criteria (P=0.03). Of the patients on ceftaroline, 61.0, 76.1, and 83.6% achieved a clinical response by days 3, 4, and 5, compared to 54.3, 69.8, and 79.3% of the ceftriaxone-treated patients. In the Cox regression, ceftaroline was associated with a shorter time to a clinical response (HR, 1.16, P=0.02). The methodology employed here provides a framework to draw comparative effectiveness inferences from phase III CAP efficacy trials.

    Pneumonia remains the leading cause of death in children outside the neonatal period, despite advances in prevention and management. Over the last 20 years, there has been a substantial decrease in the incidence of childhood pneumonia and pneumonia-associated mortality. New conjugate vaccines against Haemophilus influenzae type b and Streptococcus pneumoniae have contributed to decreases in radiologic, clinical and complicated pneumonia cases and have reduced hospitalization and mortality. The importance of co-infections with multiple pathogens and the predominance of viral-associated disease are emerging. Better access to effective preventative and management strategies is needed in low- and middle-income countries, while new strategies are needed to address the residual burden of disease once these have been implemented.

    Full Text Available Abstract Background Community-acquired pneumonia (CAP is the most frequent infection-related cause of death. The reference standard to diagnose CAP is a new infiltrate on chest radiograph in the presence of recently acquired respiratory signs and symptoms. This study aims to evaluate the diagnostic and prognostic accuracy of clinical signs and symptoms and laboratory biomarkers for CAP. Methods 545 patients with suspected lower respiratory tract infection, admitted to the emergency department of a university hospital were included in a pre-planned post-hoc analysis of two controlled intervention trials. Baseline assessment included history, clinical examination, radiography and measurements of procalcitonin (PCT, highly sensitive C-reactive protein (hsCRP and leukocyte count. Results Of the 545 patients, 373 had CAP, 132 other respiratory tract infections, and 40 other final diagnoses. The AUC of a clinical model including standard clinical signs and symptoms (i.e. fever, cough, sputum production, abnormal chest auscultation and dyspnea to diagnose CAP was 0.79 [95% CI, 0.75–0.83]. This AUC was significantly improved by including PCT and hsCRP (0.92 [0.89–0.94]; p Conclusion PCT, and to a lesser degree hsCRP, improve the accuracy of currently recommended approaches for the diagnosis of CAP, thereby complementing clinical signs and symptoms. PCT is useful in the severity assessment of CAP.

    Full Text Available Lung cavities are not typically associated with community-acquired pneumonia (CAP. CAP due to P. aeruginosa is rare and even less commonly causes necrotizing pneumonia. We report a case of P. aeruginosa CAP that progressed to necrotizing pneumonia and was eventually fatal. Procalcitonin (PCT has been well investigated in guiding antibiotic therapy (especially CAP in adults. In this case, PCT at presentation and sequentially was negative. We discuss this caveat and present hypotheses as to the sensitivity and specificity of PCT and C-reactive protein (CRP in these patients. To better characterize P. aeruginosa CAP, we undertook a review of cases indexed in PubMed from 2001 to 2016 (n=9. The data reveal that risk factors for P. aeruginosa CAP include smoking, alcohol use, obstructive lung disease, sinusitis, and hot tub use. The route of infection for P. aeruginosa CAP remains unknown. One of the most interesting findings on reviewing cases was that P. aeruginosa CAP involves the right upper lobe in the vast majority. We suggest that when physicians in the community see patients with distinctly upper lobe necrotizing or cavitary pneumonia, they should consider P. aeruginosa in their differential diagnosis. Further studies are needed to clarify route of infection, role of PCT and CRP, and optimal therapy including drug and duration.

    Prognostic scales provide a useful tool to predict mortality in community-acquired pneumonia (CAP). However, the inflammatory response of the host, crucial in resolution and outcome, is not included in the prognostic scales. The aim of this study was to investigate whether information about the initial inflammatory cytokine profile and markers increases the accuracy of prognostic scales to predict 30-day mortality. To this aim, a prospective cohort study in two tertiary care hospitals was designed. Procalcitonin (PCT), C-reactive protein (CRP) and the systemic cytokines tumour necrosis factor alpha (TNFalpha) and interleukins IL6, IL8 and IL10 were measured at admission. Initial severity was assessed by PSI (Pneumonia Severity Index), CURB65 (Confusion, Urea nitrogen, Respiratory rate, Blood pressure, > or = 65 years of age) and CRB65 (Confusion, Respiratory rate, Blood pressure, > or = 65 years of age) scales. A total of 453 hospitalised CAP patients were included. The 36 patients who died (7.8%) had significantly increased levels of IL6, IL8, PCT and CRP. In regression logistic analyses, high levels of CRP and IL6 showed an independent predictive value for predicting 30-day mortality, after adjustment for prognostic scales. Adding CRP to PSI significantly increased the area under the receiver operating characteristic curve (AUC) from 0.80 to 0.85, that of CURB65 from 0.82 to 0.85 and that of CRB65 from 0.79 to 0.85. Adding IL6 or PCT values to CRP did not significantly increase the AUC of any scale. When using two scales (PSI and CURB65/CRB65) and CRP simultaneously the AUC was 0.88. Adding CRP levels to PSI, CURB65 and CRB65 scales improves the 30-day mortality prediction. The highest predictive value is reached with a combination of two scales and CRP. Further validation of that improvement is needed.

    To analyze the usefulness and ability of procalcitonin (PCT) to predict the presence of bacteremia in patients with community-acquired pneumonia (CAP) caused by Streptococcus pneumoniae (S. pneumoniae) or other bacteria. This is an observational, prospective and descriptive study involving patients who were diagnosed with CAP in our Emergency Department. Data collected included socio-demographic and comorbidity variables, Charlson index, stage in the Pneumonia Severity Index and criteria of severe NAC, microbiologic studies and biomarker determinations (PCT and C reactive protein). The follow-up was carried out during 30 days to calculate the predictive power and the diagnostic performance for bacteremia caused or not by S. pneumoniae. Four hundred and seventy-four patients were finally included in the study. Blood cultures were positive in 85 individuals (17.9%) and S. pneumoniae was identified as the responsible pathogen in 75 of them (88.4%) (in 5 cases together with another agent). The area under the Receiver Operating Characteristic curve for PCT to predict bacteremia (caused by S. pneumoniae or not) was 0.988 (95% confidence interval 0.908-0.995; P98% and>10, respectively. The most frequently isolated serotypes of S. pneumoniae were 19A, 7F, 1 and 3. The highest mean levels of PCT were found in serotypes 7F, 19A, 3 and 1, which showed statistically significant differences with regard to the others serotypes considered (P=.008). Serotypes associated with the highest percentage of severe sepsis-septic shock, 30-days mortality and multi-lobe or bilateral affection were 3, 1 and 19A; 1, 3 and 19A; and 3, 19A and 6A, respectively. PCT had a remarkable diagnostic ability to discard or suspect bacteremia and to guide the etiology of CAP caused by S. pneumoniae. Serotypes 1, 3, 19A and 7F showed greater frequency, systemic inflammatory response and clinical severity. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    Full Text Available Research objective: to study the features of the cytokine profile and cytological status in children with community-acquired pneumonia, proceeding against a background of reduced resistance of the organism for improving treatment methods. 53 children aged 3 to 7 years were examined. The main group consisted of 30 children with community-acquired pneumonia, which ran against a background of reduced resistance of the body. The comparison group consisted of 23 children with community-acquired pneumonia who had good resistance. Local immunity was studied on the basis of  valuation of cytokine status parameters (tumor necrotic factor-α, interleukin-8, and interferon-γ and cellular composition with an estimate of destructive changes in neutrophils in induced sputum. It was revealed that in the main group of children there is a depression of the neutrophils’ release into the bronchial secretion and a marked increase in the number of neutrophils with maximum signs of destruction of the nucleus and cytoplasm against the background of cytokine status imbalance, manifested in an increase in the content of the tumor necrotic factor-α and a decrease in interleukin-8 and interferon- γ. Inclusion in the traditional therapy of community-acquired pneumonia in children who have a reduced resistance, anti-inflammatory drug fenspiride, eliminates the imbalance of proinflammatory cytokines and increases the release of functionally complete neutrophils in the bronchial secret.

    This study aimed to elucidate factors related to 30-day mortality of pneumonia occurring outside hospital by comprehensively analyzing data considered relevant to prognosis. Data considered relevant to prognosis were retrospectively examined from clinical charts and chest X-ray images of all patients with pneumonia occurring outside hospital admitted to our hospital from 2010 to 2016. The primary outcome was 30-day mortality. Data were collected from 534 patients (317 community-acquired pneumonia and 217 nursing- and healthcare associated pneumonia patients; 338 men (63.3%); mean age, 76.2 years-old). Eighty-three patients (9.9%) died from pneumonia within 30 days from the date of admission. The numbers of patients with pneumonia severity index (PSI) classes of I/II/III/IV/V and age, dehydration, respiratory failure, orientation disturbance, pressure (A-DROP) scores of 0/1/2/3/4/5 were 29/66/127/229/83, and 71/107/187/132/30/7, respectively. Mean (standard deviation) body mass index (BMI), serum albumin, blood procalcitonin, white blood cell and C-reactive protein were 20.00 (4.12) kg/m 2 , 3.16 (0.60) g/dL, 3.69 (13.15) ng/mL, 11559.4 (5656.9)/mm 3 , and 10.92 (8.75) mg/dL, respectively. Chest X-ray images from 152 patients exhibited a pneumonia shadow over a quarter of total lung field. Logistic regression analysis revealed that PSI class or A-DROP score, BMI, serum albumin, and extent of pneumonia shadow were related to 30-day mortality. Receiver operating characteristics curve analysis revealed that serum albumin was superior to PSI class or A-DROP score for predicting 30-day mortality. Serum albumin is not less important than PSI class or A-DROP score for predicting 30-day mortality in hospitalized patients with pneumonia occurring outside hospital.

    Full Text Available BACKGROUND: Bacterial pneumonia is a well described complication of influenza. In recent years, community-onset methicillin-resistant Staphylococcus aureus (cMRSA infection has emerged as a contributor to morbidity and mortality in patients with influenza. Since the emergence and rapid dissemination of pandemic A(H1N12009 influenzavirus in April 2009, initial descriptions of the clinical features of patients hospitalized with pneumonia have contained few details of patients with bacterial co-infection. METHODOLOGY/PRINCIPAL FINDINGS: Patients with community-acquired pneumonia (CAP caused by co-infection with pandemic A(H1N12009 influenzavirus and cMRSA were prospectively identified at two tertiary hospitals in one Australian city during July to September 2009, the period of intense influenza activity in our region. Detailed characterization of the cMRSA isolates was performed. 252 patients with pandemic A(H1N12009 influenzavirus infection were admitted at the two sites during the period of study. Three cases of CAP due to pandemic A(H1N12009/cMRSA co-infection were identified. The clinical features of these patients were typical of those with S. aureus co-infection or sequential infection following influenza. The 3 patients received appropriate empiric therapy for influenza, but inappropriate empiric therapy for cMRSA infection; all 3 survived. In addition, 2 fatal cases of CAP caused by pandemic A(H1N12009/cMRSA co-infection were identified on post-mortem examination. The cMRSA infections were caused by three different cMRSA clones, only one of which contained genes for Panton-Valentine Leukocidin (PVL. CONCLUSIONS/SIGNIFICANCE: Clinicians managing patients with pandemic A(H1N12009 influenzavirus infection should be alert to the possibility of co-infection or sequential infection with virulent, antimicrobial-resistant bacterial pathogens such as cMRSA. PVL toxin is not necessary for the development of cMRSA pneumonia in the setting of pandemic

    To describe the clinical characteristics and management of patients hospitalised with community-acquired pneumonia (CAP) in China. This was a multicentre, retrospective, observational study. 13 teaching hospitals in northern, central and southern China from 1 January 2014 to 31 December 2014 PARTICIPANTS: Information on hospitalised patients aged ≥14 years with radiographically confirmed pneumonia with illness onset in the community was collected using standard case report forms. Resource use for CAP management. Of 14 793 patients screened, 5828 with radiographically confirmed CAP were included in the final analysis. Low mortality risk patients with a CURB-65 score 0-1 and Pneumonia Severity Index risk class I-II accounted for 81.2% (4434/5594) and 56.4% (2034/3609) patients, respectively. 21.7% (1111/5130) patients had already achieved clinical stability on admission. A definite or probable pathogen was identified only in 12.7% (738/5828) patients. 40.9% (1575/3852) patients without pseudomonal infection risk factors received antimicrobial overtreatment regimens. The median duration between clinical stability to discharge was 5.0 days with 30-day mortality of 4.2%. These data demonstrated the overuse of health resources in CAP management, indicating that there is potential for improvement and substantial savings to healthcare systems in China.

    Full Text Available Hospital acquired pneumonia (HAP is a major complication of stroke. We sought to determine associations between infarction of specific brain regions and HAP.215 consecutive acute stroke patients with HAP (2003-2009 were carefully matched with 215 non-pneumonia controls by gender, then NIHSS, then age. Admission imaging and binary masks of infarction were registered to MNI-152 space. Regional atlas and voxel-based log-odds were calculated to assess the relationship between infarct location and the likelihood of HAP. An independently validated penalized conditional logistic regression model was used to identify HAP associated imaging regions.The HAP and control patients were well matched by gender (100%, age (95% within 5-years, NIHSS (98% within 1-point, infarct size, dysphagia, and six other clinical variables. Right hemispheric infarcts were more frequent in patients with HAP versus controls (43.3% vs. 34.0%, p = 0.054, whereas left hemispheric infarcts were more frequent in controls (56.7% vs. 44.7%, p = 0.012; there was no significant difference between groups in the rate of brainstem strokes (p = 1.0. Of the 10 most infarcted regions, only right insular cortex volume was different in HAP versus controls (20 vs. 12 ml, p = 0.02. In univariate analyses, the highest log-odds regions for pneumonia were right hemisphere, cerebellum, and brainstem. The best performing multivariate model selected 7 brain regions of infarction and 2 infarct volume-based variables independently associated with HAP.HAP is associated with right hemispheric peri-insular stroke. These associations may be related to autonomic modulation of immune mechanisms, supporting recent hypotheses of stroke mediated immune suppression.

    Measurement of the respiratory rate is an important instrument for assessing the severity of acute disease. The respiratory rate is often not measured in routine practice because its clinical utility is inadequately appreciated. In Germany, documentation of the respiratory rate is obligatory when a patient with pneumonia is hospitalized. This fact has enabled us to study the prognostic significance of the respiratory rate in reference to a large medical database. We retrospectively analyzed data from the external quality-assurance program for community-acquired pneumonia for the years 2010-2012. All patients aged 18 years or older who were not mechanically ventilated on admission were included in the analysis. Logistic regression was used to determine the significance of the respiratory rate as a risk factor for in-hospital mortality. 705,928 patients were admitted to the hospital with community-acquired pneumonia (incidence: 3.5 cases per 1000 adults per year). The in-hospital mortality of these patients was 13.1% (92 227 persons). The plot of mortality as a function of respiratory rate on admission was U-shaped and slanted to the right, with the lowest mortality at a respiratory rate of 20/min on admission. If patients with a respiratory rate of 12-20/min are used as a baseline for comparison, patients with a respiratory rate of 27-33/min had an odds ratio (OR) of 1.72 for in-hospital death, and those with a respiratory rate above 33/min had an OR of 2.55. Further independent risk factors for in-hospital death were age, admission from a nursing home, hospital, or rehabilitation facility, chronic bedridden state, disorientation, systolic blood pressure, and pulse pressure. Respiratory rate is an independent risk marker for in-hospital mortality in community-acquired pneumonia. It should be measured when patients are admitted to the hospital with pneumonia and other acute conditions.

    To determine whether the presence of hypercapnia on admission in adult patients admitted to a university-based hospital in Karachi, Pakistan with community-acquired pneumonia (CAP) correlates with an increased length of hospital stay and severity compared with no hypercapnia on admission. A prospective observational study. Tertiary care hospital in Karachi, Pakistan. Patients who met the inclusion criteria were enrolled in the study. The severity of pneumonia was assessed by CURB-65 and PSI scores. An arterial blood gas analysis was obtained within 24 hours of admission. Based on arterial PaCO 2 levels, patients were divided into three groups: hypocapnic (PaCO 2 45 mm Hg) and normocapnic (PaCO 2 <35-45 mm Hg). The primary outcome was the association of hypercapnia on admission with mean length of hospital stay. Secondary outcomes were the need for mechanical ventilation, ICU admission and in-hospital mortality. A total of 295 patients of mean age 60.20±17.0 years (157 (53.22%) men) were enrolled over a 1-year period. Hypocapnia was found in 181 (61.35%) and hypercapnia in 57 (19.32%) patients. Hypercapnic patients had a longer hospital stay (mean 9.27±7.57 days), increased requirement for non-invasive mechanical ventilation (NIMV) on admission (n=45 (78.94%)) and longer mean time to clinical stability (4.39±2.0 days) compared with the other groups. Overall mortality was 41 (13.89%), but there was no statistically significant difference in mortality (p=0.35) and ICU admission (p=0.37) between the three groups. On multivariable analysis, increased length of hospital stay was associated with NIMV use, ICU admission, hypercapnia and normocapnia. Hypercapnia on admission is associated with severity of CAP, longer time to clinical stability, increased length of hospital stay and need for NIMV. It should be considered as an important criterion to label the severity of the illness and also a determinant of patients who will require a higher level of hospital

    Purpose: To assess interobserver agreement (IOA) in the diagnosis of pulmonary infiltrates on chest X-rays for patients with community-acquired pneumonia (CAP). Materials and methods: From 7/2002 to 12/2005, 806 adults with CAP were included in the multicenter study ''CAPNETZ'' (7 hospitals). Inclusion criteria were clinical signs of pneumonia and pulmonary opacification on chest X-rays. Each X-ray was reevaluated by two radiologists from the university hospital in consensus reading against the interpreter at the referring hospital in regard to: presence of infiltrate (yes/no/equivocal), transparency (≤/> 50%), localization, and pattern of infiltrates (alveolar/interstitial). The following parameters were documented: digital or film radiography, hospitalization, fever, findings of auscultation, microbiological findings. Results: The overall IOA concerning the detection of infiltrates was 77.7% (n 626; Cl 0.75 - 0.81), the infiltrates were not verified in 16.4% (n = 132) by the referring radiologist with equivocal findings in 5.9% (n = 48). The IOA of the different clinical centers varied between 63.2% (n = 38, Cl 0.48 - 0.78) and 92.3% (n = 65, Cl 0.86 - 0.99). The IOA for the diagnosis of infiltrates was significantly higher for inpatients with 82.6% (n = 546; Cl 0.80-0.85) than for outpatients with 55.2% (n = 80; Cl 0.47 - 0.63), p 50% was 95.1% (n = 215; Cl 0.92 - 0.98) versus 80.4% (n = 403; Cl 0.77 - 0.84) for infiltrates with a transparency > 50% (p < 0.0001). In patients with positive auscultation, the IOA was higher (p = 0,034). Chest X-rays of patients with antibiotic therapy or an alveolar infiltrate showed more equivocal findings compared to patients without these features. Conclusion: There is considerable interobserver variability in the diagnosis of pulmonary infiltrates on chest radiographs. The IOA is higher in more opaque infiltrates, positive auscultation and inpatients. (orig.)

    Full Text Available Purpose. The study aimed to determine the extent of and factors influencing the prescribing of injections for the treatment of mild/moderate community acquired pneumonia (CAP in Mongolia.Methods. Questionnaires were developed and administered to medication providers (34 Pharmacists, 27 pharmacy technicians and prescribers (22 general doctors and 49 medical specialists working in Mongolia.Results. Cefalosporins were prescribed for patients with mild pneumonia and doctors tended to prescribe injectable cefalosporins (cefazolin rather than oral dosage forms. This was supported by the questionnaire study with pharmacists and pharmacy technicians. Additionally, 23 pharmacists and pharmacy technicians indicated that OTC injectable cefalosporins (37.7% and injectable aminopenicillins (33,9% were frequently sold by pharmacies for the treatment of mild/moderate CAP. Doctors and particularly pharmacists in the questionnaire studies indicated choosing an injection was to avoid non-compliance problems.Conclusion. High levels of injectable prescribing of antibiotics were found in non-hospitalized patients with CAP in Mongolia. This prevalence level indicated that inappropriate injection prescribing is a public health hazard for Mongolia and requires consideration by the appropriate authorities.

    Senior individuals older than 65 years of age are at a disproportionally higher risk of developing pneumonia. Impaired capacity to defend against airway infections may be one of the reasons. It is generally believed that weaker regulatory T cell responses may be beneficial to host defense against pathogens. In senior patients with community-acquired bacterial pneumonia, we investigated the frequencies and functions of regulatory T cells. Interestingly, we found that compared to age- and sex-matched healthy controls, senior pneumonia patients presented lower frequencies of Foxp3-expressing and Helios-expressing CD4 + T cells. The quantity of Foxp3 and Helios being expressed, measured by their mRNA transcription levels, was also lower in CD4 + T cells from pneumonia patients. Furthermore, following TCR and TGF-β stimulation, pneumonia patients presented impaired capacity to upregulate Foxp3 and Helios. Functional analyses revealed that CD4 + T cells from pneumonia patients secreted lower amounts of IL-10 and TGF-β, two cytokines critical to regulatory T cell-mediated suppression. Also, the expression of granzyme B and perforin, which were cytolytic molecules potentially utilized by regulatory T cells to mediate the elimination of antigen-presenting cells and effector T cells, were reduced in CD4 + CD25 + T cells from senior pneumonia patients. In addition, the CD4 + CD25 + T cells from senior pneumonia patients presented reduced capacity to suppress effector CD4 + and CD8 + T cell proliferation. Moreover, the value of pneumonia severity index was inversely correlated with several parameters of regulatory T cell function. Together, our results demonstrated that senior pneumonia patients presented a counterintuitive impairment in regulatory T cell responses that was associated with worse prognosis.

    Bacteriological confirmation of pneumonia (PNM) in hospitalized patients is often erratic or belated. Because of importance of prognosis, early adaptation of treatment requires an empirical antimicrobial therapy (generally aminopenicillin and macrolide combination). The starting therapeutic strategy should profit by a fast and reliable test asserting a pneumococcal etiology. The Binax Now S. pneumoniae (BNP) test allows an urinary pneumococcal antigen (UPA) detection using an immunochromatographic membrane assay within 15 minutes. We first evaluated the BNP test for 28 patients with pneumococcal PNM proved by culture, and 118 negative control patients without PNM. The BNP test was then evaluated by testing urine from 158 hospitalized patients with a clinical picture of PNM (community-acquired: 90, nosocomial: 68) for whom a research of urinary Legionella antigen (Binax Now) was prescribed and was positive for only two cases. 57 patients (36.1%) were hospitalized in ICU. The sensitivity was 71.4% (85.7% for the 21 bacteriemic PNM), and the specificity was 98.3%; that is consistent with previous published data. Among the 158 patients with PNM, UPA was detected in 17 cases (10.8%): 15 within the community-acquired PNM (16.7%) and 2 (2.9%) within the nosocomial cases. The pneumococcal etiology was confirmed by bacteriological samples in 7/17 patients (6 by blood cultures). The 10 others showed clinical and radiological features in agreement with a pneumococcal PNM. Among the 141 patients with negative AUP, S. pneumoniae was isolated from 6 of them (2 in blood cultures). The Binax Now S. pneumoniae test allowed a fast and reliable etiological diagnosis in 10.8% of hospitalized PNM (16.7% of the community-acquired cases) having a research of urinary Legionella antigen (conceiving with severity factors). So it could conduce to an improved adjustment of the starting antimicrobial therapy of hospitalized adult patients with PNM.

    Community-acquired Staphylococcus aureus (CA-SA) infections are common among pediatric patients in Hawaii. We wanted to characterize the radiological features of methicillin-susceptible (CA-MSSA) and methicillin-resistant (CA-MRSA) staphylococcal pneumonia in Hawaiian children. We retrospectively reviewed medical records and imaging studies of children with SA pneumonia identified from 1996 through 2007. Of 40 children, 26 (65%) had CA-MRSA pneumonia and 14 patients (35%) had CA-MSSA pneumonia. CA-MRSA patients were significantly younger than CA-MSSA patients (65% younger than 1 year vs. 36% older). In a majority (62%) of CA-MRSA patients, the consolidation was unilateral; in most of the CA-MSSA cases (79%), the consolidation was bilateral. Fifty percent of the patients with CA-MRSA and 21% of those with CA-MSSA had pneumatoceles (P = 0.1). CA-MRSA patients more commonly had pleural effusions (85% vs. 64% for CA-MSSA) and pleural thickening (50% vs. 36% for CA-MSSA). This case series describes the radiologic characteristics of CA-MRSA and CA-MSSA pneumonia in children in a highly endemic area. We found that CA-MRSA pneumonias are unilateral in a majority of pediatric pneumonia cases, are more common in children 1 year or younger, and have higher rates of complications in comparison to CA-MSSA patients.

    To evaluate the clinical and radiological characteristics of tuberculous pneumonia (TBPn). We compared the clinical presentation, pneumonia severity index (PSI), and radiological findings of 51 TBPn patients with those of typical pulmonary tuberculosis (PulTB) and community-acquired pneumonia (CAP) patients. The mean age of patients with TBPn was higher than that of patients with CAP or PulTB (66.6 ± 15.8 vs. 53.1 ± 17.1, 54.9 ± 15.7) (p < 0.05). Diabetes mellitus was more common in patients with TB than in those with CAP (24.1% vs. 8.2%) (p < 0.05). The PSI scores for TBPn and CAP were similar (79.5 ± 31.1 vs. 71.8 ± 28.3, respectively) and were higher than that for PulTB (64 ± 26.8) (p < 0.05). The ratio of lower lobe involvement was higher in TBPn and CAP than in PulTB (49% and 75.5% vs. 22.4%, respectively). Cavity formation and centrilobular nodules were more common in TBPn than in CAP (13.7% vs. 6.1% and 74.5% vs. 22.4%, respectively) (p < 0.05). Although TBPn shows a similar clinical presentation to CAP, it is more common in elderly patients and more commonly involves lower lobe involvement with cavity formation and centrilobular nodules. Therefore, in cases in which there may be diagnostic uncertainty, appropriate diagnostic procedures following these findings are required to differentiate these diseases.

    Full Text Available The increasing burden of pneumonia in adults is an emerging health issue in the era of global population aging. This study was conducted to elucidate the burden of community-onset pneumonia (COP and its etiologic fractions in Japan, the world's most aged society.A multicenter prospective surveillance for COP was conducted from September 2011 to January 2013 in Japan. All pneumonia patients aged ≥ 15 years, including those with community-acquired pneumonia (CAP and health care-associated pneumonia (HCAP, were enrolled at four community hospitals on four major islands. The COP burden was estimated based on the surveillance data and national statistics.A total of 1,772 COP episodes out of 932,080 hospital visits were enrolled during the surveillance. The estimated overall incidence rates of adult COP, hospitalization, and in-hospital death were 16.9 (95% confidence interval, 13.6 to 20.9, 5.3 (4.5 to 6.2, and 0.7 (0.6 to 0.8 per 1,000 person-years (PY, respectively. The incidence rates sharply increased with age; the incidence in people aged ≥ 85 years was 10-fold higher than that in people aged 15-64 years. The estimated annual number of adult COP cases in the entire Japanese population was 1,880,000, and 69.4% were aged ≥ 65 years. Aspiration-associated pneumonia (630,000 was the leading etiologic category, followed by Streptococcus pneumoniae-associated pneumonia (530,000, Haemophilus influenzae-associated pneumonia (420,000, and respiratory virus-associated pneumonia (420,000, including influenza-associated pneumonia (30,000.A substantial portion of the COP burden occurs among elderly members of the Japanese adult population. In addition to the introduction of effective vaccines for S. pneumoniae and influenza, multidimensional approaches are needed to reduce the pneumonia burden in an aging society.

    Several organizations have published evidence-based quality indicators for community-acquired pneumonia (CAP). However, there is variability in the types of indicators presented between organizations and the level of supporting evidence for each of the indicators. A systematic review of the literature and relevant Internet Web sites was performed to identify quality indicators for CAP that have been proposed or recommended by organizations, and each of the indicators was then critically appraised, using a well-defined set of criteria. The MEDLINE, EMBASE, Best Evidence, and Cochrane Systematic Review databases and Internet Web sites were searched for articles and guidelines published between January 1980 and May 2001 to identify quality indicators for CAP and relevant evidence. Experts in the area of health services research were contacted to identify additional sources. A well-defined set of criteria was applied to evaluate each of the quality indicators. The systematic review of the literature and Internet Web sites yielded 44 CAP-specific quality indicators. The critical appraisal of these indicators yielded 16 indicators that were supported by a study that identified an association between quality of care and the process of care or outcome measure, were applied to enough patients to be able to detect clinically meaningful differences, were clinically and/or economically relevant, were measurable in a clinical practice setting, and were precise in their specifications. Many organizations recommend indicators for CAP. Indicators may serve as measures of clinical performance for clinicians and hospitals, may help in benchmarking, and may ultimately facilitate improvements in quality of care and cost reductions. However, CAP indicators often vary in their meaningfulness, scientific soundness, and interpretability of results. A set of five critical appraisal questions may assist in the evaluation of which quality indicators are most valid.

    The authors of national guidelines emphasize the use of history and examination findings to diagnose community-acquired pneumonia (CAP) in outpatient children. Little is known about the interrater reliability of the physical examination in children with suspected CAP. This was a prospective cohort study of children with suspected CAP presenting to a pediatric emergency department from July 2013 to May 2016. Children aged 3 months to 18 years with lower respiratory signs or symptoms who received a chest radiograph were included. We excluded children hospitalized ≤14 days before the study visit and those with a chronic medical condition or aspiration. Two clinicians performed independent examinations and completed identical forms reporting examination findings. Interrater reliability for each finding was reported by using Fleiss' kappa (κ) for categorical variables and intraclass correlation coefficient (ICC) for continuous variables. No examination finding had substantial agreement (κ/ICC > 0.8). Two findings (retractions, wheezing) had moderate to substantial agreement (κ/ICC = 0.6-0.8). Nine findings (abdominal pain, pleuritic pain, nasal flaring, skin color, overall impression, cool extremities, tachypnea, respiratory rate, and crackles/rales) had fair to moderate agreement (κ/ICC = 0.4-0.6). Eight findings (capillary refill time, cough, rhonchi, head bobbing, behavior, grunting, general appearance, and decreased breath sounds) had poor to fair reliability (κ/ICC = 0-0.4). Only 3 examination findings had acceptable agreement, with the lower 95% confidence limit >0.4: wheezing, retractions, and respiratory rate. In this study, we found fair to moderate reliability of many findings used to diagnose CAP. Only 3 findings had acceptable levels of reliability. These findings must be considered in the clinical management and research of pediatric CAP. Copyright © 2017 by the American Academy of Pediatrics.

    There have been significant changes in community acquired pneumonia (CAP) in children in the last decade. These changes relate to epidemiology and clinical presentation. Resistance to antibiotics is also a changing issue. These all have to be considered when treating CAP. In this document, two of the main Spanish pediatric societies involved in the treatment of CAP in children, propose a consensus concerning therapeutic approach. These societies are the Spanish Society of Paediatric Infectious Diseases and the Spanish Society of Paediatric Chest Diseases. The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP) has also been involved in the prevention of CAP. An attempt is made to provide up-to-date guidelines to all paediatricians. The first part of the statement presents the approach to ambulatory, previously healthy children. We also review the prevention with currently available vaccines. In a next second part, special situations and complicated forms will be addressed. Copyright © 2014 Asociación Española de Pediatría.

    Among people who are hospitalised for community-acquired pneumonia, does an inpatient exercise-based rehabilitation program improve functional outcomes, symptoms, quality of life and length of hospital stay more than a respiratory physiotherapy regimen? Randomised trial with concealed allocation, intention-to-treat analysis and blinding of some outcomes. Forty-nine adults hospitalised for community-acquired pneumonia. The experimental group (n=32) underwent a physical training program that included warm-up, stretching, peripheral muscle strength training and walking at a controlled speed for 15 minutes. The control group (n=17) underwent a respiratory physiotherapy regimen that included percussion, vibrocompression, respiratory exercises and free walking. The intervention regimens lasted 8 days. The primary outcome was the Glittre Activities of Daily Living test, which assesses the time taken to complete a series of functional tasks (eg, rising from a chair, walking, stairs, lifting and bending). Secondary outcomes were distance walked in the incremental shuttle walk test, peripheral muscle strength, quality of life, dyspnoea, lung function, C-reactive protein and length of hospital stay. Measures were taken 1 day before and 1 day after the intervention period. There was greater improvement in the experimental group than in the control group on the Glittre Activities of Daily Living test (mean between-group difference 39 seconds, 95% CI 20 to 59) and the incremental shuttle walk test (mean between-group difference 130 m, 95% CI 77 to 182). There were also significantly greater improvements in quality of life, dyspnoea and peripheral muscle strength in the experimental group than in the control group. There were no between-group differences in lung function, C-reactive protein or length of hospital stay. The improvement in functional outcomes after an inpatient rehabilitation program was greater than the improvement after standard respiratory physiotherapy. The

    Full Text Available Monocyte chemoattractant protein (MCP-1 increases in the serum of immunocompetent patients with community-acquired pneumonia (CAP. However, the correlation between the circulating level of MCP-1 and severity of CAP remains unclear. This study investigated differential changes in the plasma MCP-1 levels of patients with CAP before and after an antibiotic treatment and further analyzes the association between the CAP severity and MCP-1 levels. We measured the plasma MCP-1 levels of 137 patients with CAP and 74 healthy controls by using a commercial enzyme-linked immunosorbent assay. Upon initial hospitalization, Acute Physiology and Chronic Health Evaluation II (APACHE II; confusion, urea level, respiratory rate, blood pressure, and age of >64 years (CURB-65; and pneumonia severity index (PSI scores were determined for assessing the CAP severity in these patients. The antibiotic treatment reduced the number of white blood cells (WBCs and neutrophils as well as the level of C-reactive protein (CRP and MCP-1. The plasma MCP-1 level, but not the CRP level or WBC count, correlated with the CAP severity according to the PSI (r = 0.509, p < 0.001, CURB-65 (r = 0.468, p < 0.001, and APACHE II (r = 0.360, p < 0.001 scores. We concluded that MCP-1 levels act in the development of CAP and are involved in the severity of CAP.

    The purpose of this study was to analyse the possible differences, especially those regarding mortality, between patients hospitalized for community-acquired pneumonia (CAP) with and without chronic obstructive pulmonary disease (COPD), and the risk factors related to mortality in the COPD group. 710 patients with CAP were included in a prospective multicenter observational study. 244 of the patients had COPD confirmed by spirometry. COPD was associated with mortality in patients with CAP (OR=2.62 CI: 1.08-6.39). Patients with COPD and CAP had a significantly higher 30-day mortality rate as compared to patients without COPD. Multivariate analysis showed that PaO(2) or =45 mmHg (OR=4.6; CI: 2.3-15.1); respiratory rate > or =30/min (OR=12.25; CI: 3.45-35.57), pleural effusion (OR=8.6; 95% CI: 2.01-24.7), septic shock (OR=12.6; 95% CI: 3.4-45.66) and renal failure (OR=13.4; 95% CI: 3.2-37.8) were significantly related to mortality. Purulent sputum and fever were considered as protective factors. COPD was an independent risk factor for mortality in patients with CAP. Hypoxemia and hypercapnia are associated with mortality in patients with CAP with and without COPD. Chronic obstructive pulmonary disease and PaCO(2) value could be useful prognostic factors and should be incorporated in risk stratification in patients with CAP.

    A significant percentage of patients with hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) have poor outcomes with intravenous antibiotics. It is not clear if adding aerosolized antibiotics improves treatment. This review is an update on using aerosolized antibiotics for treating HAP/VAP in adults. PubMed search using the terms "aerosolized antibiotics pneumonia," "nebulized antibiotics pneumonia," and "inhaled antibiotics pneumonia." Reference lists from identified articles were also searched. Clinical studies of aerosolized antibiotics for treating HAP/VAP in adults from July 2010 to March 2017. This article updates a previous review on this topic written in mid-2010. The size and quality of studies have improved dramatically in the recent time period compared to previous studies. However, there still are not large randomized controlled trials available. Colistin and aminoglycosides were the most commonly studied agents, and the most common pathogens were Pseudomonas and Acinetobacter. The clinical efficacy of adding aerosolized antibiotics was mixed. Approximately half of the studies showed better outcomes, and none showed worse outcomes. Aerosolized antibiotics appear to be relatively safe, though pulmonary adverse events can occur. Attention to proper administration technique in mechanically ventilated patients is required, including the use of vibrating plate nebulizers. Adding aerosolized antibiotics to intravenous antibiotics may improve the outcomes of adult patients with HAP/VAP in some settings. It seems reasonable to add aerosolized antibiotics in patients with multidrug-resistant organisms or who appear to be failing therapy. Clinicians should pay attention to potential adverse events and proper administration technique.

    Full Text Available BACKGROUND: MRSA remains a leading cause of hospital-acquired (HAP and healthcare-associated pneumonia (HCAP. We describe the epidemiology and outcome of MRSA pneumonia in Canadian hospitals, and identify factors contributing to mortality. METHODS: Prospective surveillance for MRSA pneumonia in adults was done for one year (2011 in 11 Canadian hospitals. Standard criteria for MRSA HAP, HCAP, ventilator-associated pneumonia (VAP, and community-acquired pneumonia (CAP were used to identify cases. MRSA isolates underwent antimicrobial susceptibility testing, and were characterized by pulsed-field gel electrophoresis (PFGE and Panton-Valentine leukocidin (PVL gene detection. The primary outcome was all-cause mortality at 30 days. A multivariable analysis was done to examine the association between various host and microbial factors and mortality. RESULTS: A total of 161 patients with MRSA pneumonia were identified: 90 (56% with HAP, 26 (16% HCAP, and 45 (28% CAP; 23 (14% patients had VAP. The mean (± SD incidence of MRSA HAP was 0.32 (± 0.26 per 10,000 patient-days, and of MRSA VAP was 0.30 (± 0.5 per 1,000 ventilator-days. The 30-day all-cause mortality was 28.0%. In multivariable analysis, variables associated with mortality were the presence of multiorgan failure (OR 8.1; 95% CI 2.5-26.0, and infection with an isolate with reduced susceptibility to vancomycin (OR 2.5, 95% CI 1.0-6.3. CONCLUSIONS: MRSA pneumonia is associated with significant mortality. Severity of disease at presentation, and infection caused by an isolate with elevated MIC to vancomcyin are associated with increased mortality. Additional studies are required to better understand the impact of host and microbial variables on outcome.

    Full Text Available Post influenza pneumonia is a leading cause of mortality and morbidity, with mortality rates approaching 60% when bacterial infections are secondary to multi-drug resistant (MDR pathogens. Staphylococcus aureus, in particular community acquired MRSA (cMRSA, has emerged as a leading cause of post influenza pneumonia.Linezolid (LZD prevents acute lung injury in murine model of post influenza bacterial pneumonia.Mice were infected with HINI strain of influenza and then challenged with cMRSA at day 7, treated with antibiotics (LZD or Vanco or vehicle 6 hours post bacterial challenge and lungs and bronchoalveolar lavage fluid (BAL harvested at 24 hours for bacterial clearance, inflammatory cell influx, cytokine/chemokine analysis and assessment of lung injury.Mice treated with LZD or Vanco had lower bacterial burden in the lung and no systemic dissemination, as compared to the control (no antibiotic group at 24 hours post bacterial challenge. As compared to animals receiving Vanco, LZD group had significantly lower numbers of neutrophils in the BAL (9×10(3 vs. 2.3×10(4, p < 0.01, which was associated with reduced levels of chemotactic chemokines and inflammatory cytokines KC, MIP-2, IFN-γ, TNF-α and IL-1β in the BAL. Interestingly, LZD treatment also protected mice from lung injury, as assessed by albumin concentration in the BAL post treatment with H1N1 and cMRSA when compared to vanco treatment. Moreover, treatment with LZD was associated with significantly lower levels of PVL toxin in lungs.Linezolid has unique immunomodulatory effects on host inflammatory response and lung injury in a murine model of post-viral cMRSA pneumonia.

  2. Are quantitative cultures useful in the diagnosis of hospital-acquired pneumonia?

    2001-02-01

    Noninvasive and invasive tests have been developed and studied for their utility in diagnosing and guiding the treatment of hospital-acquired pneumonia, a condition with an inherently high mortality. Early empiric antibiotic treatment has been shown to reduce mortality, so delaying this treatment until test results are available is not justifiable. Furthermore, tailoring therapy based on results of either noninvasive or invasive tests has not been clearly shown to affect morbidity and mortality. This may be related to quantitative limitations of these tests or possibly to a high false-negative rate in patients who receive early antibiotic treatment and may therefore have suppressed bacterial counts. Results of these tests, however, do influence treatment. It is therefore hoped that they may ultimately provide a rational basis for making therapeutic decisions. In the future, outcomes research should be a part of large-scale clinical trials, and noninvasive and invasive tests should be incorporated into the design in an attempt to provide a better understanding of the value of such tests.

    Non-HIV Pneumocystis pneumonia (PCP) can occur in immunosuppressed patients having malignancy or on immunosuppressive agents. To classify severity, the A-DROP scale proposed by the Japanese Respiratory Society (JRS), the CURB-65 score of the British Respiratory Society (BTS) and the Pneumonia Severity Index (PSI) of the Infectious Diseases Society of America (IDSA) are widely used in patients with community-acquired pneumonia (CAP) in Japan. To evaluate how correctly these conventional prognostic guidelines for CAP reflect the severity of non-HIV PCP, we retrospectively analyzed 21 patients with non-HIV PCP. A total of 21 patients were diagnosed by conventional staining and polymerase chain reaction (PCR) for respiratory samples with chest x-ray and computed tomography (CT) findings. We compared the severity of 21 patients with PCP classified by A-DROP, CURB-65, and PSI. Also, patients' characteristics, clinical pictures, laboratory results at first visit or admission and intervals from diagnosis to start of specific-PCP therapy were evaluated in both survivor and non-survivor groups. Based on A-DROP, 18 patients were classified as mild or moderate; respiratory failure developed in 15 of these 18 (83.3%), and 7/15 (46.7%) died. Based on CURB-65, 19 patients were classified as mild or moderate; respiratory failure developed in 16/19 (84.2%), and 8 of the 16 (50%) died. In contrast, PSI classified 14 as severe or extremely severe; all of the 14 (100%) developed respiratory failure and 8/14 (57.1%) died. There were no significant differences in laboratory results in these groups. The time between the initial visit and diagnosis, and the time between the initial visit and starting of specific-PCP therapy were statistically shorter in the survivor group than in the non-survivor group. Conventional prognostic guidelines for CAP could underestimate the severity of non-HIV PCP, resulting in a therapeutic delay resulting in high mortality. The most important factor to

    Full Text Available Citrobacter species, belonging to the family Enterobacteriaceae, are environmental organisms commonly found in soil, water, and the intestinal tracts of animals and humans. Citrobacter koseri is known to be an uncommon but serious cause of both sporadic and epidemic septicemia and meningitis in neonates and young infants. Most cases reported have occurred in immunocompromised hosts. The infections caused by Citrobacter are difficult to treat with usual broad spectrum antibiotics owing to rapid generation of mutants and have been associated with high death rates in the past. We believe this is the first case described in the literature of a community-acquired pneumonia and empyema caused by Citrobacter koseri in an immunocompetent adult patient.

    Community-acquired pneumonia (CAP) is an important cause of morbidity and mortality worldwide. This review summarises current trends and knowledge gaps in CAP management and prevention. Although Streptococcus pneumoniae is the most frequent cause of CAP, identification of the microbial cause of infection remains unsuccessful in most episodes, and little is known about the aetiology of CAP in immunocompromised patients. Urinary antigen testing has become standard care for diagnosing Legionella infection, and pneumococcal urinary antigen testing is now recommended in the Dutch guidelines to streamline antibiotic therapy in patients hospitalised with CAP. In primary care C-reactive protein determination is recommended to improve antibiotic prescription for lower respiratory tract infections. In patients hospitalised with CAP, three strategies are considered equally effective for choosing empirical antibiotic treatment. Yet, more (and better designed) studies are needed to determine the best strategy, as well as to determine optimal (which usually means the minimum) duration of antibiotic therapy and the role of adjuvant treatment with corticosteroids. The effectiveness of the 23-valent pneumococcal polysaccharide vaccine in preventing invasive pneumococcal disease and pneumococcal CAP remains debated, and whether the newer conjugate vaccines are more effective remains to be determined. Many of these questions are currently being addressed in large-scaled trials in the Netherlands, and their results may allow evidence-based decisions in CAP management and prevention.

The optimization of treatment of comorbid pathology by medicines which modify endothelium functional state is important. Aim: to study effect of exogenous L-arginine on clinical course of disease, markers of systemic inflammation and endothelial dysfunction in patients with coronary heart disease (CHD and community-acquired pneumonia (CAP. Materials and methods. 60 patients with CHD and CAP (the median 72.50 years, range 66.00; 75.00 were included into the study. Patients were randomized in 2 groups: first – 30 patients with basic therapy combined with L-arginine; and second – 30 patients with basic therapy. hs-CRP, neopterin, РАРР-А, NT-proBNP were measured by ELISA-TEST before treatment and 1 month after. Clinical course was assessed during 1 year of follow-up. Results. In the first group the hospitalization rate due to CHD and heart failure decompensation was significantly rare. Biomarkers changes in the 1st group were significant: hs-CRP was significantly decreased by 57.14 % (in the 2nd group – by 28.57 %; neopterin – by 36.57 % (in the 2nd group – by 20.91 %; РАРР-А – by 35.71 % (in the 2nd group – by 4.76 %. There was revealed a significant decreasing of NT-proBNP levels in patients receiving L-arginine by comparing with basic therapy: with the I stage of heart failure (HF – by 50.97 % vs 21.82 %, with the II-A stage of HF – by 43.82 % vs 5.61 % (p < 0.05.

The purpose of this study was to estimate health care resource utilization and costs among COPD patients with newly acquired pneumonia compared to those without pneumonia. Methods: A retrospective claims analysis using Truven MarketScan® Commercial and Medicare databases was conducted. COPD patients with and without newly acquired pneumonia diagnosed between January 1, 2004 and September 30, 2011 were identified. Propensity score matching was used to create a 1:1 matched cohort. Patient demographics, comorbidities (measured by Charlson Comorbidity Index, and medication use were evaluated before and after matching. Health care resource utilization (ie, hospitalizations, emergency room [ER] and outpatient visits, and associated health care costs were assessed during the 12-month follow-up. Logistic regression was conducted to evaluate the risk of hospitalization and ER visits, and gamma regression models and two-part models compared health care costs between groups after matching. Results: In the baseline cohort (N=467,578, patients with newly acquired pneumonia were older (mean age: 70 versus [vs] 63 years and had higher Charlson Comorbidity Index scores (3.3 vs 2.6 than patients without pneumonia.

    Full Text Available Abstract Background Legionella species cause severe forms of pneumonia with high mortality and complication rates. Accurate clinical predictors to assess the likelihood of Legionella community-acquired pneumonia (CAP in patients presenting to the emergency department are lacking. Methods We retrospectively compared clinical and laboratory data of 82 consecutive patients with Legionella CAP with 368 consecutive patients with non-Legionella CAP included in two studies at the same institution. Results In multivariate logistic regression analysis we identified six parameters, namely high body temperature (OR 1.67, p Legionella CAP. Using optimal cut off values of these six parameters, we calculated a diagnostic score for Legionella CAP. The median score was significantly higher in Legionella CAP as compared to patients without Legionella (4 (IQR 3–4 vs 2 (IQR 1–2, p Legionella pneumonia. Conversely, of the 73 patients (16% with ≥4 points, 66% of patients had Legionella CAP. Conclusion Six clinical and laboratory parameters embedded in a simple diagnostic score accurately identified patients with Legionella CAP. If validated in future studies, this score might aid in the management of suspected Legionella CAP.

    Severity assessment scores were first developed to predict the 30 day mortality in community acquired pneumonia; however, several guidelines have extended their use to guide empirical antibiotic prescription decisions. This approach has theoretical advantages because a decrease in broad-spectrum antibiotic treatment in low-risk patients might reduce antibiotic-related side-effects, and to give broad-spectrum therapy to patients at higher risk of death is intuitive. However, evidence in support of this approach is not clear. In particular, the British Thoracic Society guidelines suggest withholding a macrolide from patients with low CURB 65 scores, despite evidence that these patients have a higher frequency of atypical pathogens than do those with a higher severity of pneumonia. Severity scores do not perform well in some groups and might overestimate disease severity in elderly people, leading to inappropriate broad-spectrum treatment to those at high risk of complications such as Clostridium difficile infection. In this Review, we discuss the evidence for antibiotic prescribing guided by severity score and suggest that more evidence of effect and implementation is needed before this approach can be universally adopted.

    Community-acquired pneumonia (CAP) is not considered a professional disease, and the effect of different occupations and working conditions on susceptibility to CAP is unknown. The aim of this study is to determine whether different jobs and certain working conditions are risk factors for CAP. Over a 1-year period, all radiologically confirmed cases of CAP (n=1,336) and age- and sex-matched controls (n=1,326) were enrolled in a population-based case-control study. A questionnaire on CAP risk factors, including work-related questions, was administered to all participants during an in-person interview. The bivariate analysis showed that office work is a protective factor against CAP, while building work, contact with dust and sudden changes of temperature in the workplace were risk factors for CAP. The occupational factor disappeared when the multivariate analysis was adjusted for working conditions. Contact with dust (previous month) and sudden changes of temperature (previous 3 months) were risk factors for CAP, irrespective of the number of years spent working in these conditions, suggesting reversibility. Some recent working conditions such as exposure to dust and sudden changes of temperature in the workplace are risk factors for CAP. Both factors are reversible and preventable.

    Coagulase-negative staphylococci recently have been implicated as a cause of serious infections in immunocompromised individuals. An unusual case of community-acquired pneumonia due to Staphylococcus cohnii in an HIV-infected drug user is described. Results of a study conducted to examine the prevalence of infection due to Staphylococcus cohnii strains and their antibiotic-sensitivity patterns show a low frequency but a high morbidity. These results and a brief review of the literature emphasize the importance of these organisms and other staphylococcal species as emerging opportunistic pathogens in patients with AIDS.

    Full Text Available Additional healthcare visits and rehospitalizations after discharge are frequent among patients with community-acquired pneumonia (CAP and have a major impact on healthcare costs. We aimed to determine whether the implementation of an individualized educational program for hospitalized patients with CAP would decrease subsequent healthcare visits and readmissions within 30 days of hospital discharge.A multicenter, randomized trial was conducted from January 1, 2011 to October 31, 2014 at three hospitals in Spain. We randomly allocated immunocompetent adults patients hospitalized for CAP to receive either an individualized educational program or conventional information before discharge. The educational program included recommendations regarding fluid intake, adherence to drug therapy and preventive vaccines, knowledge and management of the disease, progressive adaptive physical activity, and counseling for alcohol and smoking cessation. The primary trial endpoint was a composite of the frequency of additional healthcare visits and rehospitalizations within 30 days of hospital discharge. Intention-to-treat analysis was performed.We assigned 102 patients to receive the individualized educational program and 105 to receive conventional information. The frequency of the composite primary end point was 23.5% following the individualized program and 42.9% following the conventional information (difference, -19.4%; 95% confidence interval, -6.5% to -31.2%; P = 0.003.The implementation of an individualized educational program for hospitalized patients with CAP was effective in reducing subsequent healthcare visits and rehospitalizations within 30 days of discharge.

    Full Text Available Abstract Background Non-HIV Pneumocystis pneumonia (PCP can occur in immunosuppressed patients having malignancy or on immunosuppressive agents. To classify severity, the A-DROP scale proposed by the Japanese Respiratory Society (JRS, the CURB-65 score of the British Respiratory Society (BTS and the Pneumonia Severity Index (PSI of the Infectious Diseases Society of America (IDSA are widely used in patients with community-acquired pneumonia (CAP in Japan. To evaluate how correctly these conventional prognostic guidelines for CAP reflect the severity of non-HIV PCP, we retrospectively analyzed 21 patients with non-HIV PCP. Methods A total of 21 patients were diagnosed by conventional staining and polymerase chain reaction (PCR for respiratory samples with chest x-ray and computed tomography (CT findings. We compared the severity of 21 patients with PCP classified by A-DROP, CURB-65, and PSI. Also, patients’ characteristics, clinical pictures, laboratory results at first visit or admission and intervals from diagnosis to start of specific-PCP therapy were evaluated in both survivor and non-survivor groups. Results Based on A-DROP, 18 patients were classified as mild or moderate; respiratory failure developed in 15 of these 18 (83.3%, and 7/15 (46.7% died. Based on CURB-65, 19 patients were classified as mild or moderate; respiratory failure developed in 16/19 (84.2%, and 8 of the 16 (50% died. In contrast, PSI classified 14 as severe or extremely severe; all of the 14 (100% developed respiratory failure and 8/14 (57.1% died. There were no significant differences in laboratory results in these groups. The time between the initial visit and diagnosis, and the time between the initial visit and starting of specific-PCP therapy were statistically shorter in the survivor group than in the non-survivor group. Conclusions Conventional prognostic guidelines for CAP could underestimate the severity of non-HIV PCP, resulting in a therapeutic delay

    To analyse the usefulness and performance of several biomarkers [C-reactive protein (CRP), mid-regional pro-adrenomedullin (MR-proADM), procalcitonin (PCT)] and lactate in predicting short- and medium-term mortality compared with the prognostic severity scales (PSS) usually employed for community-acquired pneumonia (CAP) and in assessing the aetiological suspicion of infection by Streptococcus pneumoniae and bacteraemia. Observational, prospective and analytical study was conducted on patients who were diagnosed with CAP in our emergency department (ED). The data collected included socio-demographic and comorbidity variables, Charlson index, priority level according to the Spanish Triage System (STS), stage in the Pneumonia Severity Index (PSI) and in the CURB-65 (confusion, urea, respiratory rate, blood pressure and age ≥65years), criteria of severe CAP, microbiological studies, and biomarkers determinations. The patients were followed-up for 180days to calculate the prognostic power and the diagnostic performance for bacteraemia and aetiology. A total of 127patients were finally enrolled in the study. The 30-day mortality was 10.3% (13), and 22.6% (28) at 180 days. Blood cultures were positive in 29 patients (23%) and S.pneumoniae was identified as the responsible pathogen in 28 cases (22.2%). The area under the ROC curve (AUC-ROC) for lactate and MR-proADM to predict 30-day mortality was 0.898 (95%CI: 0.824-0.973; P0.85ng/ml, the NPV and the LR+ were 96.6% and 5.89%, respectively, to predict a S.pneumoniae infection. MR-proADM and lactate showed a similar or even better performance for 30-day intra-hospital mortality than PSI, CURB-65, STS and CAP severity criteria in patients diagnosed with CAP (P>.05). Furthermore, the MR-proADM capacity to predict 180-day mortality was higher than PSS and the rest of biomarkers (P>.05), and its AUC-ROC increased if it was used in combination with PSI, CURB65 and STS. The determination of PCT has a remarkable diagnostic

    Conclusion: Morbidity and mortality in pregnant patients with pneumonia continue to present a significant challenge. Early recognition of the diseases process and prompt treatment are required to ascertain an optimal outcome. The treatments in the gravid patients generally follow standard guide lines for the treatment of pneumonia in adults. Concern for fetal outcome should not delay treatment as improvement in maternal oxygenation and status is the best way to ensure fetal protection.

    To investigate the incidence, severity, and prognostic value of acute kidney injury (AKI) in patients with community-acquired pneumonia (CAP). A total of 293 CAP patients (185 men and 108 women; mean age 54.3±17.1 years) were examined. AKI was diagnosed and classified in accordance with the 2012 KDIGO guidelines. On admission, the serum concentration of creatinine averaged 104.5±73.3 µmol/l. AKI was diagnosed in 83 (28.3%) patients with CAP. Hospital-acquired AKI was found in 25 (8.5%) patients, which amounted to 30.1% of all the AKI cases. The disease severity according to both the CURB-65 scale and the CRB-65 scale, which neglect blood urea nitrogen concentrations, was higher than that in patients with CAP associated with AKI (1.4±1.0 versus 0.4±0.6 scores; respectively; р<0.0001 and 0.8±0.7 versus 0.3±0.5 scores, respectively р<0.0001). The disease ended in a fatal outcome in 16 (5.5%) patients. The mortality in the presence of AKI was higher: 9 (10.1%) patients died in the AKI-complicated CAP group; that in the absence of AKI was 7 (5.2%; χ(2)=4.78; р=0.03), the odds ratio for death in the patients with CAP associated with AKI was 3.4; 95% confidence interval, 2.27 to 17.46. Multivariate logistic regression analysis revealed that the occurrence of AKI was independently influenced by age (р<0.001), systolic and diastolic blood pressures (p=0.01 and p=0.01, respectively), and a history of urinary tract diseases (p=0.04) and diabetes mellitus (p<0.001). AKI complicates CAP in 28.3% of cases and increases mortality in patients with CAP. The predictors of AKI in CAP patients are old age, hemodynamic disorders, diabetes mellitus, and prior urinary tract diseases.

    At the present time the alternation of the oxidative metabolism is considered as one of the leading pathogenic mechanisms in the development and progression of community-acquired pneumonia (CAP). However the nature and direction of the oxidative protein changes in CAP patient's blood had been almost unexplored. To define oxidative and modified proteins in erythrocytes and blood plasma of CAP patients. Blood plasma and erythrocytes obtained from: 42 patients with moderate severity pneumonia, 12 patients with grave severity pneumonia and 32 healthy volunteers. Content of advanced oxidation protein products, malondialdehyde and reactive carbonyl derivatives were estimated as indicators of the oxidative stress and oxidative damage of proteins. In patients with grave severity the level of oxidative proteins and MDA in erythrocytes exceeded both: control values and similar meanings in CAP patients with moderate severity. The further growth of MDA in this group patients' blood plasma was observed, but the level of oxidative proteins decreased in comparison with those in CAP patients with moderate severity. To sum up, our derived data show, that injury of erythrocytes' redox-status and blood plasma components plays an essential role in development and progression CAP.

    2016-01-01

    Full Text Available Methicillin-resistant Staphylococcus aureus (MRSA is an important cause of infection, both in hospitalised patients with significant healthcare exposure and in patients without healthcare risk factors. Community-acquired methicillin-resistant S. aureus (CA-MRSA are known for their rapid community transmission and propensity to cause aggressive skin and soft tissue infections and community-acquired pneumonia. The distinction between the healthcare-associated (HA-MRSA and CA-MRSA is gradually fading owing to the acquisition of multiple virulence factors and genetic elements. The movement of CA-MRSA strains into the nosocomial setting limits the utility of using clinical risk factors alone to designate community or HA status. Identification of unique genetic characteristics and genotyping are valuable tools for MRSA epidemiological studies. Although the optimum pharmacotherapy for CA-MRSA infections has not been determined, many CA-MRSA strains remain broadly susceptible to several non-β-lactam antibacterial agents. This review aimed at illuminating the characteristic features of CA-MRSA, virulence factors, changing clinical settings and molecular epidemiology, insurgence into the hospital settings and therapy with drug resistance.

    Defining health care-associated pneumonia, which includes both hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP), is problematic and controversial. Aspiration pneumonia is often included as a subtype of HAP but may be related to community-acquired aspiration events. Scoring systems exist and new surveillance guidelines have been implemented to make early recognition of pneumonia more precise and objective. Management and prevention should follow recommendations, including early empirical therapy, targeted therapy, and limited duration of treatment. Patients with trauma present a challenge to the diagnosis and management of pneumonia, because of increased risk for aspiration and underlying chest and pulmonary injury.

    Intensive care unit (ICU)-acquired pneumonia and ventilator-associated pneumonia (VAP) are associated with poor clinical and economic outcomes. Data regarding ICU-acquired pneumonia and VAP are not readily available from developing countries, including China. The objective of this meta-analysis was to evaluate the incidence, mortality rate, length of stay, and pathogens associated with ICU-acquired pneumonia in China. A meta-analysis and systematic review of 334 publications published between January 2007 and May 2012 and retrieved from the Chinese BioMedical database, China National Knowledge Infrastructure, VIP Chinese Science and Technique Journals database, Wanfang database, and PubMed was conducted. The incidences of ICU-acquired pneumonia and VAP were 16.2% (95% confidence interval (CI) 12.8-20.4%) and 33.7% (95% CI 31.4-36.1%), respectively; mortality rates were 37.4% (95% CI 24.6-52.2%) and 34.5% (95% CI 29.2-40.1%), respectively. The durations of stay in the ICU and hospital were 12.4 (95% CI 9.6-15.3) and 17.7 (95% CI 15.6-19.7) days and 18.0 (95% CI 16.5-19.6) and 30.5 (95% CI 26.4-34.7) days for ICU-acquired pneumonia and VAP, respectively. Pseudomonas aeruginosa (19.9%) and Acinetobacter baumannii (13.9%) were the most frequently isolated pathogens, followed by Klebsiella pneumoniae (11.9%) and Staphylococcus aureus (10.4%); 82.9% of S. aureus isolates were reported to be methicillin-resistant. ICU-acquired pneumonia/VAP remains a major cause of morbidity and mortality in patients in the ICU in China. Data on organisms causing disease in this population could help guide appropriate prevention strategies and treatment. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Limited information exists on the clinical characteristics predictive of mortality in patients aged ≥65 years in many countries. The impact of adherence to current antimicrobial guidelines on the mortality of hospitalized elderly patients with community-acquired pneumonia (CAP) has never been assessed. A total of 3131 patients aged ≥65 years were enrolled from a multi-center, retrospective, observational study initiated by the CAP-China network. Risk factors for death were screened with multivariable logistic regression analysis, with emphasis on the evaluation of age, comorbidities and antimicrobial treatment regimen with regard to the current Chinese CAP guidelines. The mean age of the study population was 77.4 ± 7.4 years. Overall in-hospital and 60-day mortality were 5.7% and 7.6%, respectively; these rates were three-fold higher in those aged ≥85 years than in the 65-74 group (11.9% versus 3.2% for in-hospital mortality and 14.1% versus 4.7% for 60-day mortality, respectively). The mortality was significantly higher among patients with comorbidities compared with those who were otherwise healthy. According to the 2016 Chinese CAP guidelines, 62.1% of patients (1907/3073) received non-adherent treatment. For general-ward patients without risk factors for Pseudomonas aeruginosa (PA) infection (n = 2258), 52.3% (1094/2090) were over-treated, characterized by monotherapy with an anti-pseudomonal β-lactam or combination with fluoroquinolone + β-lactam; while 71.4% of intensive care unit (ICU) patients (120/168) were undertreated, without coverage of atypical bacteria. Among patients with risk factors for PA infection (n = 815), 22.9% (165/722) of those in the general ward and 74.2% of those in the ICU (69/93) were undertreated, using regimens without anti-pseudomonal activity. The independent predictors of 60-day mortality were age, long-term bedridden status, congestive heart failure, CURB-65, glucose, heart rate, arterial oxygen

    It is important to realize that guidelines cannot always account for individual variation among patients. They are not intended to supplant physician judgment with respect to particular patients or special clinical situations. IDSA considers adherence to these guidelines to be voluntary, with the ultimate determination regarding their application to be made by the physician in the light of each patient's individual circumstances. These guidelines are intended for use by healthcare professionals who care for patients at risk for hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP), including specialists in infectious diseases, pulmonary diseases, critical care, and surgeons, anesthesiologists, hospitalists, and any clinicians and healthcare providers caring for hospitalized patients with nosocomial pneumonia. The panel's recommendations for the diagnosis and treatment of HAP and VAP are based upon evidence derived from topic-specific systematic literature reviews. PMID:27418577

    Pneumonia is an acute inflammation of the lower respiratory tract. Lower respiratory tract infection is a major cause of mortality worldwide. Pneumonia is most common at the extremes of life. Predisposing factors in children include an under-developed immune system together with other factors, such as malnutrition and over-crowding. In adults, tobacco smoking is the single most important preventable risk factor. The commonest infecting organisms in children are respiratory viruses and Streptoccocus pneumoniae. In adults, pneumonia can be broadly classified, on the basis of chest radiographic appearance, into lobar pneumonia, bronchopneumonia and pneumonia producing an interstitial pattern. Lobar pneumonia is most commonly associated with community acquired pneumonia, bronchopneumonia with hospital acquired infection and an interstitial pattern with the so called atypical pneumonias, which can be caused by viruses or organisms such as Mycoplasma pneumoniae. Most cases of pneumonia can be managed with chest radiographs as the only form of imaging, but CT can detect pneumonia not visible on the chest radiograph and may be of value, particularly in the hospital setting. Complications of pneumonia include pleural effusion, empyema and lung abscess. The chest radiograph may initially indicate an effusion but ultrasound is more sensitive, allows characterisation in some cases and can guide catheter placement for drainage. CT can also be used to characterise and estimate the extent of pleural disease. Most lung abscesses respond to medical therapy, with surgery and image guided catheter drainage serving as options for those cases who do not respond.

    National guidance from the United Kingdom and the United States on community-acquired pneumonia in children states that chest radiographs are not recommended routinely in uncomplicated cases. The main reason in the ambulatory setting is that there is no evidence of a substantial impact on clinical outcomes. However clinical practice and adherence to guidance is multifactorial and includes the clinical context (developed vs. developing world), the confidence of the attending physician, the changing incidence of complications (according to the success of immunisation programs), the availability of alternative imaging (and its relationship to perceived risks of radiation) and the reliability of the interpretation of imaging. In practice, chest radiographs are performed frequently for suspected pneumonia in children.

    National guidance from the United Kingdom and the United States on community-acquired pneumonia in children states that chest radiographs are not recommended routinely in uncomplicated cases. The main reason in the ambulatory setting is that there is no evidence of a substantial impact on clinical outcomes. However clinical practice and adherence to guidance is multifactorial and includes the clinical context (developed vs. developing world), the confidence of the attending physician, the changing incidence of complications (according to the success of immunisation programs), the availability of alternative imaging (and its relationship to perceived risks of radiation) and the reliability of the interpretation of imaging. In practice, chest radiographs are performed frequently for suspected pneumonia in children. Time pressures facing clinicians at the front line, difficulties in distinguishing which children require admission, restricted bed numbers for admissions, imaging-resource limitations, perceptions regarding risk from procedures, novel imaging modalities and the probability of other causes for the child's presentation all need to be factored into a guideline. Other drivers that often weigh in, depending on the setting, include cost-effectiveness and the fear of litigation. Not all guidelines designed for the developed world can therefore be applied to the developing world, and practice guidelines require regular review in the context of new information. In addition, radiologists must improve radiographic diagnosis of pneumonia, reach consensus on the interpretive terminology that clarifies their confidence regarding the presence of pneumonia and act to replace one imaging technique with another whenever there is proof of improved accuracy or reliability.

    2011-01-01

    Background Patients with Enterobacter community-acquired pneumonia (EnCAP) were admitted to our intensive care unit (ICU). Our primary aim was to describe them as few data are available on EnCAP. A comparison with CAP due to common and typical bacteria was performed. Methods Baseline clinical, biological and radiographic characteristics, criteria for health-care-associated pneumonia (HCAP) were compared between each case of EnCAP and thirty age-matched typical CAP cases. A univariate and multivariate logistic regression analysis was performed to determine factors independently associated with ENCAP. Their outcome was also compared. Results In comparison with CAP due to common bacteria, a lower leukocytosis and constant HCAP criteria were associated with EnCAP. Empiric antibiotic therapy was less effective in EnCAP (20%) than in typical CAP (97%) (p < 0.01). A delay in the initiation of appropriate antibiotic therapy (3.3 ± 1.6 vs. 1.2 ± 0.6 days; p < 0.01) and an increase in duration of mechanical ventilation (8.4 ± 5.2 vs. 4.0 ± 4.3 days; p = 0.01) and ICU stay were observed in EnCAP patients. Conclusions EnCAP is a severe infection which is more consistent with HCAP than with typical CAP. This retrospectively suggests that the application of HCAP guidelines should have improved EnCAP management. PMID:21569334

    To determine the extent and pattern of treatment failure (TF) among children hospitalised with community-acquired pneumonia at a large tertiary hospital in Kenya. We followed up children aged 2-59 months with WHO-defined severe pneumonia (SP) and very severe pneumonia (VSP) for up to 5 days for TF using two definitions: (i) documentation of pre-defined clinical signs resulting in change of treatment (ii) primary clinician's decision to change treatment with or without documentation of the same pre-defined clinical signs. We enrolled 385 children. The risk of TF varied between 1.8% (95% CI 0.4-5.1) and 12.4% (95% CI 7.9-18.4) for SP and 21.4% (95% CI 15.9-27) and 39.3% (95% CI 32.5-46.4) for VSP depending on the definition applied. Higher rates were associated with early changes in therapy by clinician in the absence of an obvious clinical rationale. Non-adherence to treatment guidelines was observed for 70/169 (41.4%) and 67/201 (33.3%) of children with SP and VSP, respectively. Among children with SP, adherence to treatment guidelines was associated with the presence of wheeze on initial assessment (P = 0.02), while clinician non-adherence to guideline-recommended treatments for VSP tended to occur in children with altered consciousness (P < 0.001). Using propensity score matching to account for imbalance in the distribution of baseline clinical characteristics among children with VSP revealed no difference in TF between those treated with the guideline-recommended regimen vs. more costly broad-spectrum alternatives [risk difference 0.37 (95% CI -0.84 to 0.51)]. Before revising current pneumonia case management guidelines, standardised definitions of TF and appropriate studies of treatment effectiveness of alternative regimens are required. © 2014 The Authors.

    Community-acquired pneumonia (CAP) is amongst the leading causes of death worldwide. As inflammatory markers, cytokines can predict outcomes, if interpreted together with clinical data and scoring systems such as CURB-65, CRB, and Acute Physiology and Chronic Health Evaluation II (APACHE II). The aim of this study was to determine the impact of inflammatory biomarkers on the early mortality of hospitalized CAP patients. Twenty-seven CAP patients needing hospitalization were enrolled for the study and samples of interleukin-1 (IL-1) and interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), C-reactive protein (CRP), and homocystein were collected at the time of admission (day 1) as well as on the seventh day of the treatment. There was a significant reduction in the levels of IL-6 between the first and the second collections. Median IL-6 values decreased from 24 pg/mL (day 1) to 8 pg/mL (day 7) (P=0.016). The median levels of TNF-α were higher in patients: i) with acute kidney injury (AKI) (P=0.045), ii) requiring mechanical ventilation (P=0.040), iii) with short hospital stays (P=0.009), iv) admitted to the intensive care unit (ICU) (P=0.040), v) who died early (P=0.003), and vi) with worse CRB scores (P=0.013). In summary, IL-6 and TNF-α levels were associated with early mortality of CAP patients. Longer admission levels demonstrated greater likelihood of early death and overall mortality, necessity of mechanical ventilation, and AKI

    BACKGROUND: Infection in humans has been linked with altered cytokine gene transcription. It is unclear whether this phenomenon is a consequence of an established disease process or precedes the infective process. The primary end point of this study was to determine whether hospital-acquired pneumonia (HAP) was associated with differential gene expression of interferon (IFN)-gamma, tumor necrosis factor (TNF)-alpha, and IL-23p19. The secondary end point was to identify whether alteration in gene expression preceded the clinical onset of infection. METHODS: Sixty consecutive patients undergoing elective thoracic surgery were recruited. HAP was diagnosed as per National Nosocomial Infection Surveillance guidelines. Messenger RNA (mRNA) and protein levels were analyzed preoperatively and 24 h and 5 days postoperatively. RESULTS: Forty-one patients had an uncomplicated recovery. Nineteen patients developed HAP. IL-6, IL-10, IL-12p35, IL-23p19, IL-27p28, TNF-alpha, and IFN-gamma mRNA and protein levels of IL-6, IL-23, and IFN-gamma in peripheral blood leukocytes were analyzed before surgery and 24 h and 5 days postsurgery. IL-23p19 mRNA levels were reduced in the pneumonia group (median, 4.19; 10th-90th centile range, 3.90-4.71) compared with the nonpneumonia group (4.50; 3.85-5.32) day 1 postsurgery (P=02). IFN-gamma mRNA levels were reduced in the pneumonia group (2.48; 1.20-3.20) compared with nonpneumonia group (2.81; 2.10-3.26) (P=03) day 5 postsurgery. Results are expressed as log to base 10 copy numbers of cytokine mRNA per 10 million beta-actin mRNA copy numbers. All values are given as median and 10th to 90th centile range. CONCLUSIONS: Cytokine gene expression is altered immediately following surgery in patients with postoperative HAP.

    Streptococcus pneumoniae is a leading cause of pneumonia worldwide. However, the burden of pneumococcal pneumonia among adults in low- and middle-income countries is not well described. Data from 2008-2012 was analyzed from two surveillance sites in Guatemala to describe the incidence of pneumococcal pneumonia in adults. A case of hospitalized pneumococcal pneumonia was defined as a positive pneumococcal urinary antigen test or blood culture in persons aged ≥ 18 years hospitalized with an acute respiratory infection (ARI). Among 1595 adults admitted with ARI, 1363 (82%) had either urine testing (n = 1286) or blood culture (n = 338) performed. Of these, 188 (14%) had pneumococcal pneumonia, including 173 detected by urine only, 8 by blood culture only, and 7 by both methods. Incidence rates increased with age, with the lowest rate among 18-24 year-olds (2.75/100,000) and the highest among ≥65 year-olds (31.3/100,000). The adjusted incidence of hospitalized pneumococcal pneumonia was 18.6/100,000 overall, with in-hospital mortality of 5%. An important burden of hospitalized pneumococcal pneumonia in adults was described, particularly for the elderly. However, even adjusted rates likely underestimate the true burden of pneumococcal pneumonia in the community. These data provide a baseline against which to measure the indirect effects of the 2013 introduction of the pneumococcal conjugate vaccine in children in Guatemala.

    Full Text Available Community-acquired pneumonia (CAP is the infectious disease with the highest number of deaths worldwide. Nevertheless, its importance is often underestimated. Large cohorts of patients with CAP have been established worldwide and improved our knowledge about CAP by far. Therefore, current guidelines are much more evidence-based than ever before. This article discusses recent major studies and concepts on CAP such as the role of biomarkers, appropriate risk stratification to identify patients in need of hospitalisation or intensive care, appropriate empiric antibiotic therapy (including the impact of macrolide combination therapy and antibiotic stewardship, and CAP prevention with novel influenza and pneumococcal vaccines.

    The prevention of hospital-acquired pressure ulcers (PrUs) has significant consequences for patient outcomes and the cost of care. Providers are challenged with evaluating available evidence and best practices, then implementing programs and motivating change in various facility environments. In a large system of community hospitals, the Reducing Hospital Acquired-PrUs Program was developed to provide a toolkit of best practices, timely and appropriate data for focusing efforts, and continuous implementation support. Baseline data on PrU rates helped focus efforts on the most vulnerable patients and care situations. Facilities were empowered to use and adapt available resources to meet local needs and to share best practices for implementation across the system. Outcomes were measured by the rate of hospital-acquired PrUs, as gathered from patient discharge records. The rate of hospital-acquired stage III and IV PrUs decreased 66.3% between 2011 and 2013. Of the 149 participating facilities, 40 (27%) had zero hospital-acquired stage III and IV PrUs and 77 (52%) had a reduction in their PrU rate. Rates of all PrUs documented as present on admission did not change during this period. A comparison of different strategies used by the most successful facilities illustrated the necessity of facility-level flexibility and recognition of local workflows and patient demographics. Driven by the combination of a repository of evidence-based tools and best practices, readily available data on PrU rates, and local flexibility with processes, the Reducing Hospital Acquired-PrUs Program represents the successful operationalization of improvement in a wide variety of facilities.

    Ventilation/perfusion lung scintigraphy was performed in 39 patients with verified diagnosis of community-acquired pneumonia (CAP) and in 14 patients with peripheral lung cancer. Ventilation/perfusion ratio, apical-basal gradients of ventilation (U/L(V)) and lung perfusion (U/L(P)), and alveolar capillary permeability of radionuclide aerosol were determined based on scintigraphy data. The study demonstrated that main signs of CAP were increases in ventilation/perfusion ratio, perfusion and ventilation gradient on a side of the diseased lung, and two-side increase in alveolar capillary permeability rate for radionuclide aerosol. Unlike this, scintigraphic signs of peripheral lung cancer comprise an increase in ventilation/perfusion ratio over 1.0 on a side of the diseased lung with its simultaneous decrease on a contralateral side, normal values of perfusion and ventilation gradients of both lungs, and delayed alveolar capillary clearance in the diseased lung compared with the intact lung.

    Directory of Open Access Journals (Sweden)

    Ronald Anderson

    2018-04-01

    Full Text Available Pneumolysin (PLY, a member of the family of Gram-positive bacterial, cholesterol-dependent, β-barrel pore-forming cytolysins, is the major protein virulence factor of the dangerous respiratory pathogen, Streptococcus pneumoniae (pneumococcus. PLY plays a major role in the pathogenesis of community-acquired pneumonia (CAP, promoting colonization and invasion of the upper and lower respiratory tracts respectively, as well as extra-pulmonary dissemination of the pneumococcus. Notwithstanding its role in causing acute lung injury in severe CAP, PLY has also been implicated in the development of potentially fatal acute and delayed-onset cardiovascular events, which are now recognized as being fairly common complications of this condition. This review is focused firstly on updating mechanisms involved in the immunopathogenesis of PLY-mediated myocardial damage, specifically the direct cardiotoxic and immunosuppressive activities, as well as the indirect pro-inflammatory/pro-thrombotic activities of the toxin. Secondly, on PLY-targeted therapeutic strategies including, among others, macrolide antibiotics, natural product antagonists, cholesterol-containing liposomes, and fully humanized monoclonal antibodies, as well as on vaccine-based preventive strategies. These sections are preceded by overviews of CAP in general, the role of the pneumococcus as the causative pathogen, the occurrence and types of CAP-associated cardiac complication, and the structure and biological activities of PLY.

    Severe community-acquired pneumonia (CAP) is usually defined as pneumonia that requires intensive care unit (ICU) admission; the primary pathogen responsible for ICU admission is Streptococcus pneumoniae. In this study, the 2007 Infectious Diseases Society of America/American Thoracic Society (IDSA/ATS) consensus criteria for ICU admission were compared with other severity scores in predicting ICU admission and mortality. We retrospectively studied 158 patients with pneumococcal CAP (1999-2003). Clinical and laboratory features at the emergency department were recorded and used to calculate the 2007 IDSA/ATS rule, the 2001 ATS rule, 2 modified 2007 IDSA/ATS rules, the Pneumonia Severity Index (PSI), and the CURB (confusion, urea, respiratory rate, blood pressure) score. The sensitivity, specificity, positive predictive value, and negative predictive value (NPV) were assessed for the various indices. We also determined the criteria that were independently predictive of ICU admission and of mortality in our population. The 2007 IDSA/ATS criteria performed as well as the 2001 ATS rule in predicting ICU admission both demonstrated high sensitivity (90%) and NPV (97%). For the prediction of mortality, the best tool proved to be the PSI score (sensitivity, 95%; NPV, 99%). The variables associated with ICU admission in this patient population included tachypnea, confusion, Pao(2)/Fio(2) ratio of 250 or lower, and hypotension requiring fluid resuscitation. Mechanical ventilation and PSI class V were independently associated with mortality. This study confirms the usefulness of the new criteria in predicting severe CAP. The 2001 ATS criteria seem an attractive alternative because they are simple and as effective as the 2007 IDSA/ATS criteria.

    Clinical practice guidelines serve as a framework for physicians to make decisions and to support best practice for optimizing patient care. However, if the guidelines do not address all the important components of optimal care sufficiently, the quality and validity of the guidelines can be reduced. The objectives of this study were to systematically review current guidelines for hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP), evaluate their methodological quality and highlight the similarities and differences in their recommendations for empirical antibiotic and antibiotic de-escalation strategies. This review is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Electronic databases including MEDLINE, CINAHL, PubMed and EMBASE were searched up to September 2017 for relevant guidelines. Other databases such as NICE, Scottish Intercollegiate Guidelines Network (SIGN) and the websites of professional societies were also searched for relevant guidelines. The quality and reporting of included guidelines were assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE-II) instrument. Six guidelines were eligible for inclusion in our review. Among 6 domains of AGREE-II, "clarity of presentation" scored the highest (80.6%), whereas "applicability" scored the lowest (11.8%). All the guidelines supported the antibiotic de-escalation strategy, whereas the majority of the guidelines (5 of 6) recommended that empirical antibiotic therapy should be implemented in accordance with local microbiological data. All the guidelines suggested that for early-onset HAP/VAP, therapy should start with a narrow spectrum empirical antibiotic such as penicillin or cephalosporins, whereas for late-onset HAP/VAP, the guidelines recommended the use of a broader spectrum empirical antibiotic such as the penicillin extended spectrum carbapenems and glycopeptides.

Results Among 1595 adults admitted with ARI, 1363 (82%) had either urine testing (n = 1286) or blood culture (n = 338) performed. Of these, 188 (14%) had pneumococcal pneumonia, including 173 detected by urine only, 8 by blood culture only, and 7 by both methods. Incidence rates increased with age, with the lowest rate among 18–24 year-olds (2.75/100,000) and the highest among ≥65 year-olds (31.3/100,000). The adjusted incidence of hospitalized pneumococcal pneumonia was 18.6/100,000 overall, with in-hospital mortality of 5%. Conclusions An important burden of hospitalized pneumococcal pneumonia in adults was described, particularly for the elderly. However, even adjusted rates likely underestimate the true burden of pneumococcal pneumonia in the community. These data provide a baseline against which to measure the indirect effects of the 2013 introduction of the pneumococcal conjugate vaccine in children in Guatemala. PMID:26488871

    Full Text Available BACKGROUND: The role of inhaled steroids in patients with chronic respiratory diseases is a matter of debate due to the potential effect on the development and prognosis of community-acquired pneumonia (CAP. We assessed whether treatment with inhaled steroids in patients with chronic bronchitis, COPD or asthma and CAP may affect early outcome of the acute pneumonic episode. METHODS: Over 1-year period, all population-based cases of CAP in patients with chronic bronchitis, COPD or asthma were registered. Use of inhaled steroids were registered and patients were followed up to 30 days after diagnosis to assess severity of CAP and clinical course (hospital admission, ICU admission and mortality. RESULTS: Of 473 patients who fulfilled the selection criteria, inhaled steroids were regularly used by 109 (23%. In the overall sample, inhaled steroids were associated with a higher risk of hospitalization (OR=1.96, p = 0.002 in the bivariate analysis, but this effect disappeared after adjusting by other severity-related factors (adjusted OR=1.08, p=0.787. This effect on hospitalization also disappeared when considering only patients with asthma (OR=1.38, p=0.542, with COPD alone (OR=4.68, p=0.194, but a protective effect was observed in CB patients (OR=0.15, p=0.027. Inhaled steroids showed no association with ICU admission, days to clinical recovery and mortality in the overall sample and in any disease subgroup. CONCLUSIONS: Treatment with inhaled steroids is not a prognostic factor in COPD and asthmatic patients with CAP, but could prevent hospitalization for CAP in patients with clinical criteria of chronic bronchitis.

    Community-acquired pneumonia (CAP) has multiple causes and is associated with illness that requires admission to the hospital and mortality. The causes of atypical CAP include Legionella species, Chlamydophila, and Mycoplasma. Atypical CAP remains a diagnostic challenge and, therefore, likely is undertreated. This article reviews the advancements in the evaluation and treatment of patients and discusses current conflicts and controversies of atypical CAP. Copyright © 2016 Elsevier Inc.

    the aims of the present study were to evaluate the clinical and microbiological characteristics of patients suffering from community-acquired pneumonia attended in the Internal Medical Departments of several Spanish institutions and to analyze those prognostic factors predicting thirty-day mortality in such patients. Past medical history, symptoms and signs, radiological pattern and blood parameters including albumin and C Reactive Protein, were recorded for each patient. Time from admission to starting antibiotics (in hours) and follow-up (in days) were also recorded. Patients were stratified by the Pneumonia Severity Index in five risk classes. 389 patients were included in the study, most of them in Fine categories III to V. Mortality rate for all patients was 12.1% (48 patients), increasing up to 40% in Fine Class V. Neither age, sex nor time from admission to the start of antibiotic treatment predicted survival rates. Plasmatic levels of PCR or microbiologic diagnosis were not related to clinical outcome. In the Cox regression analysis, oriented patients (OR 0.138, IC95% 0.055-0.324), and those with normal albuminemia (OR 0.207, IC95% 0.103-0.417) showed better survival rates. On the contrary, those with active carcinoma (OR 3.2, IC95% 1.181-8.947) significantly showed a reduced life expectancy. Besides the fully accepted Fine scale criteria, albumin measurements should be included in routine evaluation in order to improve patient s prognostic classification.

    Full Text Available Compliance with community-acquired pneumonia (CAP guidelines remains poor despite a substantial body of evidence indicating that guideline-concordant care improves patient outcomes. The aim of this study was to compare the relative effectiveness of a general educational and a targeted emergency department intervention on improving physicians' concordance with CAP guidelines.Two distinct interventions were implemented over specific time periods. The first intervention was educational, focusing on the development of local CAP guidelines and their dissemination through hospital-wide educational programmes. The second intervention was a targeted one for the emergency department, where a clinical pathway for the initial management of CAP patients was introduced, followed by monthly feedback to the emergency department (ED physicians about concordance rates with the guidelines. Data on the concordance rate to CAP guidelines was collected from a retrospective chart review.A total of 398 eligible patient records were reviewed to measure concordance to CAP guidelines over the study period. Concordance rates during the baseline and educational intervention periods were similar (28.1% vs. 31.2%; p > 0.05. Significantly more patients were treated in accordance with the CAP guidelines after the ED focused intervention when compared to the baseline (61.5% vs. 28.1%; p < 0.05 or educational period (61.5% vs. 31.2%; p < 0.05.A targeted intervention with a CAP clinical pathway and monthly feedback was a successful strategy to increase adherence to empirical antibiotic recommendations in CAP guidelines.

    Full Text Available According to literature data, patients with community acquired pneumonia (CAP fall into several groups of unfavorable prognostic factors. Development of thrombotic complications is one of causes of mortality of hospitalized patients. In this case systemic inflammation, which is always present in moderate and severe CAP, is the starting mechanism of formation of disorders in the hemostasis system. The aim of our work was to determine anamnestic, clinical, laboratory and pathologic anatomical features in patients with CAP, taking into account markers of systemic inflammation and coagulogram indices, as well as predicting the occurrence of complications. In the course of the work, a retrospective analysis of 151 medical histories of hospitalized patients with CAP was made. We analyzed anthropometric indicators, complaints at the time of hospitalization, results of physical examination, results of the chest X-ray, clinical and laboratory indicators, microbiological sputum analysis and to assess the possibility of thrombotic complications a RAM scale was used. It was found that late asking for medical help, the presence of mixed infection, underestimation of the severity of condition and severe systemic inflammation increase the risk of lethal outcome in patients with CAP. Considering a high risk of thrombosis in patients with CAP, it is necessary to assess the risk of thrombotic complications with the help of special scales, as well as timely detection and correction of disorders from the hemostasis system.

    Our objective was to compare therapeutic outcome and analyse cost-benefit of a 'conventional' (7-day course of i.v. antibiotic therapy) vs. an abbreviated (2-day i.v. antibiotic course followed by 'switch' to oral antibiotics) therapy for in-patients with community-acquired pneumonia (CAP). We used a multicenter prospective, randomized, parallel group with a 28 day follow-up, at the University-based teaching hospitals: The Medical Center of Louisiana in New Orleans, LA and hospitals listed in the acknowledgement. Ninety-five patients were randomized to receive either a 'conventional' course of intravenous antibiotic therapy with cefamandole 1 g i.v. every 6 h for 7 days (n = 37), or an abbreviated course of intravenous therapy with cefamandole (1 g i.v. every 6 h for 2 days) followed by oral therapy with cefaclor (500 mg every 8 h for 5 days). No difference was found in the clinical courses, cure rates, survival or the resolution of the chest radiograph abnormalities among the two groups. The mean duration of therapy (6.88 days for the conventional group compared to 7-30 days for the early oral therapy group) and the frequencies of overall symptomatic improvement (97% vs. 95%, respectively) were similar in both groups. Patients who received early oral therapy had shorter hospital stays (7.3 vs. 9.71 days, P = 0.01), and a lower total cost of care ($2953 vs. $5002, P < 0.05). It was concluded that early transition to an oral antibiotic after an abbreviated course of intravenous therapy in CAP is substantially less expensive and has comparable efficacy to conventional intravenous therapy. Altering physicians' customary management of hospitalized patients with CAP can reduce costs with no appreciable additional risk of adverse patient outcome.

    The clinical and radiological features of viral pneumonias are summarized and discussed. Although viral infections of the lung belong to atypical pneumonias they demonstrate not always the radiographic pattern of an interstitial pneumonia. Characteristic radiographic findings are quite rare. In most cases the microbial etiology cannot be predicted from chest radiographs. The appearance varies depending on the virulence of the organism and the resistence of the host. In this regard knowledge of epidemiological data as well as patients condition and underlying disease is of utmost importance. Differentiation between community- and hospital-acquired infection may be very helpful. (orig.) [de

    Community-acquired pneumonia (CAP) severity scores perform well in predicting mortality of CAP patients, but their applicability in influenza pneumonia is powerless. The aim of our research was to test the efficiency of PO 2 /FiO 2 and CAP severity scores in predicting mortality and intensive care unit (ICU) admission with influenza pneumonia patients. We reviewed all patients with positive influenza virus RNA detection in Beijing Chao-Yang Hospital during the 2009-2014 influenza seasons. Outpatients, inpatients with no pneumonia and incomplete data were excluded. We used receiver operating characteristic curves (ROCs) to verify the accuracy of severity scores or indices as mortality predictors in the study patients. Among 170 hospitalized patients with influenza pneumonia, 30 (17.6%) died. Among those who were classified as low-risk (predicted mortality 0.1%-2.1%) by pneumonia severity index (PSI) or confusion, urea, respiratory rate, blood pressure, age ≥65 year (CURB-65), the actual mortality ranged from 5.9 to 22.1%. Multivariate logistic regression indicated that hypoxia (PO 2 /FiO 2  ≤ 250) and lymphopenia (peripheral blood lymphocyte count pneumonia confirmed a similar pattern and PO 2 /FiO 2 combined lymphocyte count was also the best predictor for predicting ICU admission. In conclusion, we found that PO 2 /FiO 2 combined lymphocyte count is simple and reliable predictor of hospitalized patients with influenza pneumonia in predicting mortality and ICU admission.

    The incidence of community-acquired pneumonia complications has increased during the last decade. According to the records from several countries, empyema and necrotizing pneumonia became more frequent during the last few years. The optimal therapeutic approach for such conditions is still controversial. Both pharmacological management (antimicrobials and fibrinolysis), and surgical management (pleural drainage and video-assisted thoracoscopic surgery), are the subject of continuous assessment. In this paper, the Spanish Society of Paediatric Infectious Diseases and the Spanish Society of Paediatric Chest Diseases have reviewed the available evidence. Consensus treatment guidelines are proposed for complications of community-acquired pneumonia in children, focusing on parapneumonic pleural effusion. Recommendations are also provided for the increasing population of patients with underlying diseases and immunosuppression. Copyright © 2014 Asociación Española de Pediatría.

    Anaerobes are the first and Streptococcus species the second most common cause of community-acquired lung abscess (CALA) in the West. The etiologic pathogens of this disease have changed in Taiwan, with Klebsiella pneumoniae being reported as the most common cause of CALA. To determine the etiologies of community-acquired lung abscess. We retrospectively reviewed the records of 205 Japanese adult patients with CALA to evaluate etiologies and outcomes. We used not only traditional microbiological investigations but also percutaneous ultrasonography-guided transthoracic needle aspiration and protected specimen brushes. Of these 205 patients, 122 had documented bacteriological results, with 189 bacterial species isolated. Pure aerobic, mixed aerobic and anaerobic, and pure anaerobic bacteria were isolated in 90 (73.8%), 17 (13.9%), and 15 (12.3%) patients, respectively. The four most common etiologic pathogens were Streptococcus species (59.8%), anaerobes (26.2%), Gemella species (9.8%), and K. pneumoniae (8.2%). Streptococcus mitis was the most common among the Streptococcus species. Mean duration of antibiotic administration was 26 days. Six patients (2.9%, 3 with actinomycosis and 3 with nocardiosis) were treated with antibiotics for 76-189 days. Two patients with anaerobic lung abscess died. The first and second most common etiologic pathogens of CALA in our hospital were Streptococcus species and anaerobes, respectively. The etiologies in our study differ from those in Taiwan and are similar to those in the West with the exception that Streptococcus species were the most common etiologic pathogens in our study whereas anaerobes are the most frequent etiologic pathogens in Western countries. S. mitis and Gemella species are important etiologic pathogens as well. The identification of Actinomyces and Nocardia is important in order to define the adequate duration of antibiotic administration. Copyright 2010 S. Karger AG, Basel.

    The cost of antibiotic therapy for the treatment of pneumonia in the inpatient paediatric population can have a major impact on the healthcare expenditure. We planned to assess the direct and indirect costs of diagnosis and medical treatment of paediatric patients with community acquired pneumonia who are hospitalized in a tertiary care hospital in India. 125 children with a diagnosis of pneumonia who were admitted to the inpatient department of a paediatric hospital receiving antibiotic treatment were observed. Data on clinical presentation and resources consumed were collected and the costs of pneumonia treatment were calculated. Descriptive statistics (mean ± standard deviation (SD)) were used to evaluate data regarding demographics, drugs prescribed and cost (direct and indirect cost). Multivariate regression analysis was used to find out predictors of direct and indirect cost. Among all pneumonia admissions, mild-to-moderate pneumonia constitutes 76.8%, and 23.2% children were admitted with severe pneumonia; 105 children out of 125 (84%) were suffering from associated disorders along with pneumonia. The majority of antibiotics prescribed belonged to beta lactams (52%) followed by aminoglycosides (19%), macrolides (13%) and peptides (11%). Parenteral routes of administration were used in a majority of patients as compared to oral. The average cost per patient in management of pneumonia was 12245 ± 593 INR ($187.34 ± 9.07).

    Full Text Available Introduction: Community-acquired pneumonia (CAP is associated with high morbidity and mortality rates. Despite methicillin-resistant Staphylococcus aureus (MRSA having often been associated with nosocomial pneumonia, the condition of some MRSA CAP patients is severe enough to warrant their being admitted to ICU. Objective: The purpose of this study is to conduct a systematic review of the literature on antibiotic treatment of MRSA CAP in critically-ill patients. Material and methods: An online search was conducted for locating articles on MRSA CAP in critically ill patients. Relevant publications were identified in PUBMED, the BestPractice database, UpToDate database and the Cochrane Library for articles published in English within the December 2001 - April 2016 time frame. Results: A total of 70 articles were found to have been published, 13 (18.8% having been included and 57 (81.4% excluded. Cohort studies were predominant, having totaled 16 in number (20.7% as compared to one sole cross-sectional study (3.5%. Conclusions: The experience in the treatment of MRSA CAP in patients requiring admission to ICU is quite limited. Vancomycin or linezolid seem to be the treatments of choice for MRSA CAP, although there not be any specific recommendation in this regard. It may be useful to use alternative routes, such as administration via aerosolized antibiotics, continuous infusion or in association with other antibiotics.

    To evaluate community-specific nursing home performance with community-specific hospital 30-day readmissions for Medicare patients discharged with acute myocardial infarction, heart failure or pneumonia. Cross-sectional study using 2009-2012 hospital risk-standardised 30-day readmission data for Medicare fee-for-service patients hospitalised for all three conditions and nursing home performance data from the Centers for Medicare & Medicaid Services Five-Star Quality Rating System. Medicare-certified nursing homes and acute care hospitals. 12,542 nursing homes and 3,039 hospitals treating 30 or more Medicare fee-for-service patients for all three conditions across 2,032 hospital service areas in the United States. Community-specific hospital 30-day risk-standardised readmission rates. Community-specific nursing home performance measures: health inspection, staffing, Registered Nurses and quality performance; and an aggregated performance score. Mixed-effects models evaluated associations between nursing home performance and hospital 30-day risk-standardised readmission rates for all three conditions. The relationship between community-specific hospital risk-standardised readmission rates and community-specific overall nursing home performance was statistically significant for all three conditions. Increasing nursing home performance by one star resulted in decreases of 0.29% point (95% CI: 0.12-0.47), 0.78% point (95% CI: 0.60-0.95) and 0.46% point (95% CI: 0.33-0.59) of risk-standardised readmission rates for AMI, HF and pneumonia, respectively. Among the specific measures, higher performance in nursing home overall staffing and Registered Nurse staffing measures was statistically significantly associated with lower hospital readmission rates for all three conditions. Notable geographic variation in the community-specific nursing home performance was observed. Community-specific nursing home performance is associated with community-specific hospital 30-day

    Full Text Available Human herpesvirus, 6 type (HHV-6 was isolated at the end of the 20th century from the blood leukocytes of patients with lymphoproliferative diseases. Serological studies conducted in different countries, indicate ubiquitylation of the HHV-6 and the existence of two antigenic variants - HHV-6A and HHV-6B. Their high tropism is determined in vitro to lymphocytic, nervous and dendritic cells of the CNS. Virus replicates in many cell, primary and passaged cultures of different origins. The reproduction cycle of HHV-6 continues on average 4-5 days forming syncytiums and intracytoplasmic and intranuclear inclusions. Significant destruction and lysis almost 90 % of infected cells is reported after 5-10 day of monitoring. The utility of experimentation investigating the role of HHV-6 in the development of acute and chronic diseases in respiratory tract is caused by the fact that many patients, particularly those with chronic diseases, have complaints to chronic fatigue, decreased performance and low-grade temperature more than 3-6 months. Several studies demonstrate the presence of HHV-6 in saliva, salivary and bronchiolar glands, in swabs from pharyngonasal cavity and gorge. Tropism of HHV-6 to oropharyngeal epithelium with the possibility of finding the virus in the saliva and swabs from pharyngonasal cavity and gorge was found at the end of 20th century. This fact gave the basis for work determining the level of infection by this pathogen in patients with infectious and inflammatory pathology of the respiratory tract. Materials and methods. Serological studies were conducted with 38 soldiers affected by community-acquired pneumonia. Most of the surveyed patients were ranged in age from 20 to 45 years old, middle age (32,5±1,5 years. Patients were in stationary treatment in the Kharkov military hospital. The criteria for inclusion in the study on the infection of HHV-6 were soldiers affected by community-acquired pneumonia with atypical course of

    The spread of Extended Spectrum β-lactamases (ESBLs) among Enterobacteriaceae and other Gram-Negative pathogens in the community and hospitals represents a major challenge to combat infections. We conducted a study to assess the prevalence and genetic makeup of ESBL-type resistance in bacterial isolates causing community- and hospital-acquired urinary tract infections. A total of 172 isolates of Enterobacteriaceae were collected in Dar es Salaam, Tanzania, from patients who met criteria of community and hospital-acquired urinary tract infections. We used E-test ESBL strips to test for ESBL-phenotype and PCR and sequencing for detection of ESBL genes. Overall 23.8% (41/172) of all isolates were ESBL-producers. ESBL-producers were more frequently isolated from hospital-acquired infections (32%, 27/84 than from community-acquired infections (16%, 14/88, p Enterobacteriaceae causing both hospital- and community-acquired infections in Tanzania.

    We evaluated differences in processes and outcomes of HIV-related pneumonia care among patients in Veterans Affairs (VA), public, and for-profit and not-for-profit private hospitals in the United States. We compared the results of our current study (1995 to 1997) with those of our previous study that included a sample of patients receiving care during the years 1987 to 1990 to determine how HIV-related pneumonia care had evolved over the last decade. The sample consisted of 1,231 patients with HIV infection who received care for Pneumocystis carinii pneumonia (PCP) and 750 patients with HIV infection who received care for community-acquired pneumonia (CAP) during the years 1995 to 1997. We conducted a retrospective medical record review and evaluated patient and hospital characteristics, HIV-related processes of care (timely use of anti-PCP medications, adjunctive corticosteroids), non-HIV-related processes of care (timely use of CAP treatment medications, diagnostic testing, ICU utilization, rates of endotracheal ventilation, placement on respiratory isolation), length of inpatient hospital stay, and inpatient mortality. Rates of timely use of antibiotics and adjunctive corticosteroids for treating PCP were high and improved dramatically from the prior decade. However, compliance with consensus guidelines that recommend public, private not-for-profit hospitals, and for-profit hospitals. This study provides the first overview of HIV-related pneumonia care in the early highly active antiretroviral therapy era, and contrasts current findings with those of a similarly conducted study from a decade earlier. Quality of care for patients with PCP improved, but further efforts are needed to facilitate the appropriate management of CAP. In the third decade of the epidemic, it will be important to monitor whether variations in processes of care for various HIV-related clinical diagnoses among different types of hospitals persist.

    This study aimed to describe the burden of community-acquired acute kidney injury (AKI) in China based on a nationwide survey about AKI. Cross-sectional and retrospective study. A national sample of 2,223,230 hospitalized adult patients from 44 academic/local hospitals in Mainland China was used. AKI was defined according to the 2012 KDIGO AKI creatinine criteria or an increase or decrease in serum creatinine level of 50% during the hospital stay. Community-acquired AKI was identified when a patient had AKI that could be defined at hospital admission. The rate, cause, recognition, and treatment of community-acquired AKI were stratified according to hospital type, latitude, and economic development of the regions in which the patients were admitted. All-cause in-hospital mortality and recovery of kidney function at hospital discharge. 4,136 patients with community-acquired AKI were identified during the 2 single-month snapshots (January 2013 and July 2013). Of these, 2,020 (48.8%) had cases related to decreased kidney perfusion; 1,111 (26.9%), to intrinsic kidney disease; and 499 (12.1%), to urinary tract obstruction. In the north versus the south, more patients were exposed to nephrotoxins or had urinary tract obstructions. 536 (13.0%) patients with community-acquired AKI had indications for renal replacement therapy (RRT), but only 347 (64.7%) of them received RRT. Rates of timely diagnosis and appropriate use of RRT were higher in regions with higher per capita gross domestic product. All-cause in-hospital mortality was 7.3% (295 of 4,068). Delayed AKI recognition and being located in northern China were independent risk factors for in-hospital mortality, and referral to nephrology providers was an independent protective factor. Possible misclassification of AKI and community-acquired AKI due to nonstandard definitions and missing data for serum creatinine. The features of community-acquired AKI varied substantially in different regions of China and were closely

    Nocardiosis is a rare but severe pyogenic or granulomatous disease and caused by Nocardia that mainly infects immunocompromised patients. We report here a case of an immunocompetent 24-year-old male student with community-acquired pneumonia with asymptomatic disseminated cerebral abscess by Brasiliensis nocardiosis. The patient was fully recovered after receiving optimized antimicrobial therapy without relapse. This case suggests the health professionals such as the physicians of pulmonary, infection, neurology department and et al should always think about unusual cause of community acquired pneumonia, even in immunocompetent patients and when having pulmonary nocardiosis we should do a radiological neurological work up, even with the absence of neurological finding or symptom.

    AIM: To assess inter-observer variation in the interpretation of chest radiographs of individuals with pneumonia versus those without pneumonia. MATERIALS AND METHODS: Chest radiographs of out-patients with a lower respiratory tract infection (LRTI) were assessed for the presence of infiltrates by radiologists from three local hospitals and were reassessed by one university hospital radiologist. Various measures of inter-observer agreement were calculated. RESULTS: The observed proportional agreement was 218 in 243 patients (89.7%). Kappa was 0.53 (moderate agreement) with a 95% confidence interval of 0.37 to 0.69. The observed positive agreement (59%) was much lower than for negative agreement (94%). Kappa was considerably lower, if chronic obstructive pulmonary disease was present ({kappa}=0.20) or Streptococcus pneumoniae ({kappa}=-0.29) was the infective agent. CONCLUSION: The overall inter-observer agreement adjusted for chance was moderate. Inter-observer agreement in cases with pneumonia was much worse than the agreement in negative (i.e. non-pneumonia) cases. A general practitioner's selection of patients with a higher chance of having pneumonia for chest radiography would thus not improve the observer agreement.

    evaluate the agreement between the criteria used for hospitalization of patients with community-acquired pneumonia (CAP and those of the Brazilian Thoracic Association guidelines, and to evaluate the association of that agreement with 30-day mortality. Secondarily, to evaluate the agreement between the treatment given and that recommended in the guidelines with length of hospital stay, microbiological profile, 12-month mortality, complications, ICU admission, mechanical ventilation, and 30-day mortality. METHODS: This was a retrospective study involving adult patients hospitalized between 2005 and 2007 at the Federal University of Minas Gerais Hospital das Clínicas, located in Belo Horizonte, Brazil. Medical charts and chest X-rays were reviewed. RESULTS: Among the 112 patients included in the study, admission and treatment criteria were in accordance with the guidelines in 82 (73.2% and 66 (58.9%, respectively. The 30-day and 12-month mortality rates were 12.3% and 19.4%, respectively. The 30-day mortality rate was lower for patients in whom the CRB-65 (mental Confusion, Respiratory rate, Blood pressure, and age > 65 years score was 1-2 and the antibiotic therapy was in accordance with the guidelines (p = 0.01. Cerebrovascular disease and appropriate antibiotic therapy showed independent associations with 30-day mortality. There was a trend toward an association between guideline-concordant antibiotic therapy and shorter hospital stay. CONCLUSIONS: In the population studied, admission and treatment criteria that were in accordance with the guidelines were associated with favorable outcomes in hospitalized patients with CAP. Cerebrovascular disease, as a risk factor, and guideline-concordant antibiotic therapy, as a protective factor, were associated with 30-day mortality.

    Full Text Available The clinical characteristics of Q fever are poorly identified in the tropics. Fever with pneumonia or hepatitis are the dominant presentations of acute Q fever, which exhibits geographic variability. In southern Taiwan, which is located in a tropical region, the role of Q fever in community-acquired pneumonia (CAP has never been investigated.During the study period, May 2012 to April 2013, 166 cases of adult CAP and 15 cases of acute Q fever were prospectively investigated. Cultures of clinical specimens, urine antigen tests for Streptococcus pneumoniae and Legionella pneumophila, and paired serologic assessments for Mycoplasma pneumoniae, Chlamydophila pneumoniae, and Q fever (Coxiella burnetii were used for identifying pathogens associated with CAP. From April 2004 to April 2013 (the pre-study period, 122 cases of acute Q fever were also included retrospectively for analysis. The geographic distribution of Q fever and CAP cases was similar. Q fever cases were identified in warmer seasons and younger ages than CAP. Based on multivariate analysis, male gender, chills, thrombocytopenia, and elevated liver enzymes were independent characteristics associated with Q fever. In patients with Q fever, 95% and 13.5% of cases presented with hepatitis and pneumonia, respectively. Twelve (7.2% cases of CAP were seropositive for C. burnetii antibodies, but none of them had acute Q fever. Among CAP cases, 22.9% had a CURB-65 score ≧2, and 45.8% had identifiable pathogens. Haemophilus parainfluenzae (14.5%, S. pneumoniae (6.6%, Pseudomonas aeruginosa (4.8%, and Klebsiella pneumoniae (3.0% were the most common pathogens identified by cultures or urine antigen tests. Moreover, M. pneumoniae, C. pneumoniae, and co-infection with 2 pathogens accounted for 9.0%, 7.8%, and 1.8%, respectively.In southern Taiwan, Q fever is an endemic disease with hepatitis as the major presentation and is not a common etiology of CAP.

    Objective To determine the extent and pattern of treatment failure (TF) among children hospitalised with community-acquired pneumonia at a large tertiary hospital in Kenya. Methods We followed up children aged 2–59 months with WHO-defined severe pneumonia (SP) and very severe pneumonia (VSP) for up to 5 days for TF using two definitions: (i) documentation of pre-defined clinical signs resulting in change of treatment (ii) primary clinician's decision to change treatment with or without documentation of the same pre-defined clinical signs. Results We enrolled 385 children. The risk of TF varied between 1.8% (95% CI 0.4–5.1) and 12.4% (95% CI 7.9–18.4) for SP and 21.4% (95% CI 15.9–27) and 39.3% (95% CI 32.5–46.4) for VSP depending on the definition applied. Higher rates were associated with early changes in therapy by clinician in the absence of an obvious clinical rationale. Non-adherence to treatment guidelines was observed for 70/169 (41.4%) and 67/201 (33.3%) of children with SP and VSP, respectively. Among children with SP, adherence to treatment guidelines was associated with the presence of wheeze on initial assessment (P = 0.02), while clinician non-adherence to guideline-recommended treatments for VSP tended to occur in children with altered consciousness (P grupos en la distribución de las características clínicas de base de los niños con NMS, se observó que no existían diferencias en FT entre aquellos tratados con el régimen recomendado por las guías versus alternativas más costosas de amplio espectro (diferencias de riesgo 0.37 (IC 95% -0.84 a 0.51). Conclusión Antes de revisar las actuales guías de manejo de casos de neumonía, se requieren definiciones estandarizadas de FT y estudios apropiados de la efectividad del tratamiento de regímenes alternativos.

    Clinical decision making relative to community-acquired pneumonia (CAP) diagnosis is difficult. Chest radiograph is key in establishing parenchymal lung involvement. However, radiologic performance may lead to misdiagnosis, rendering questionable the use of chest computed tomography (CT) scan in patients with clinically suspected CAP. To assess whether early multidetector chest CT scan affects diagnosis and management of patients visiting the emergency department with suspected CAP. A total of 319 prospectively enrolled patients with clinically suspected CAP underwent multidetector chest CT scan within 4 hours. CAP diagnosis probability (definite, probable, possible, or excluded) and therapeutic plans (antibiotic initiation/discontinuation, hospitalization/discharge) were established by emergency physicians before and after CT scan results. The adjudication committee established the final CAP classification on Day 28. Chest radiograph revealed a parenchymal infiltrate in 188 patients. CAP was initially classified as definite in 143 patients (44.8%), probable or possible in 172 (53.8%), and excluded in 4 (1.2%). CT scan revealed a parenchymal infiltrate in 40 (33%) of the patients without infiltrate on chest radiograph and excluded CAP in 56 (29.8%) of the 188 with parenchymal infiltrate on radiograph. CT scan modified classification in 187 (58.6%; 95% confidence interval, 53.2-64.0), leading to 50.8% definite CAP and 28.8% excluded CAP, and 80% of modifications were in accordance with adjudication committee classification. Because of CT scan, antibiotics were initiated in 51 (16%) and discontinued in 29 (9%), and hospitalization was decided in 22 and discharge in 23. In CAP-suspected patients visiting the emergency unit, early CT scan findings complementary to chest radiograph markedly affect both diagnosis and clinical management.

    Clinical characteristics, etiologies, evolution, and prognostic factors of community-acquired bacterial meningitis in elderly patients are not well known. To improve this knowledge, all episodes of community-acquired bacterial meningitis were prospectively recorded and cases occurring in patients >or=65 years old were selected. During the period 1977-2006, 675 episodes in adults (aged >or=18 yr) were recorded, with 185 (27%) in patients aged >or=65 years old; 76 were male and 109 were female, with a mean age of 73 +/- 6 years (range, 65-93 yr). Causative microorganisms were Streptococcus pneumoniae 74, Neisseria meningitidis 49, Listeria monocytogenes 17, other streptococcal 9, Escherichia coli 6, Haemophilus influenzae 4, Klebsiella pneumoniae and Staphylococcus aureus 2 each, Capnocytophaga canimorsus and Enterococcus faecalis 1 each, and unknown in 20. On admission 91% had had fever, 32% were in a coma (Glasgow Coma Scale or=65 yr), who showed a higher frequency of diabetes and malignancy as underlying disease; pneumonia, otitis, and pericranial fistula as predisposing factors; and S. pneumoniae and L. monocytogenes as etiology. There were also differences in clinical presentation, complications, sequelae, and mortality. Factors independently related with mortality were age, pneumonia as a predisposing factor, coma on admission, and heart failure and seizures after therapy. Dexamethasone therapy was a protective factor. In conclusion, bacterial meningitis in elderly patients is associated with greater diagnostic difficulties and neurologic severity and more complications, as well as with increased mortality. Antiseizure prophylaxis might be useful in these patients.

    Usefulness of CURB-65 and pneumonia severity index for influenza A H1N1v pneumonia. A. Estella. Different prognostic scales have been documented to assess the severity and indications for hospitalization and ICU admissions of community acquired pneumonia. During the past two years Influenza A H1N1v infections have been commonly attended to in emergency departments. The aim of the study was to analyse the usefulness of the application of the Pneumonia Severity Index (PSI) and CURB-65 prognostic scales in patients with primary viral pneumonia caused by influenza A H1N1v. A retrospective study was performed at a community hospital with a 17 bed-intensive care unit. Patients admitted in hospital with influenza A H1N1v pneumonia over a two year period were analysed. CURB 65 and PSI scales were applied in the emergency department and outcome and destination of admission were analysed. 24 patients were registered, 19 required ICU admission and 5 patients were admitted in medical wards. Most of the patients admitted to the intensive care unit (78.9%) required mechanical ventilation. Mortality was 21.1%. Most patients admitted to the ICU had CURB 65 scale of 1 (60%), 13.3% obtained 0 and 26.7% 2. PSI scale resulted class I in a 20%, class II 40%, 26.7% class IV and 13.3% class V. The scales CURB 65 and PSI showed no differences in scores according to the destination of admission and mortality. Use of CURB-65 and PSI in the emergency department may underestimate the risk of patients with Influenza A H1N1v pneumonia. Based in our results, the ability of these scales to predict ICU admissions for Influenza A H1N1v pneumonia is questioned.

It interferes with critical processes in the bacterial cell such as DNA replication, transcription, repair, and recombination by inhibiting bacterial topoisomerases. Levofloxacin has broad spectrum activity against several causative bacterial pathogens of community-acquired pneumonia (CAP. Oral levofloxacin is rapidly absorbed and is bioequivalent to the intravenous formulation such that patients can be conveniently transitioned between these formulations when moving from the inpatient to the outpatient setting. Furthermore, levofloxacin demonstrates excellent safety, and has good tissue penetration maintaining adequate concentrations at the site of infection. The efficacy and tolerability of levofloxacin 500 mg once daily for 10 days in patients with CAP are well established. Furthermore, a high-dose (750 mg and short-course (5 days of once-daily levofloxacin has been approved for use in the US in the treatment of CAP, acute bacterial sinusitis, acute pyelonephritis, and complicated urinary tract infections. The high-dose, short-course levofloxacin regimen maximizes its concentration-dependent antibacterial activity, decreases the potential for drug resistance, and has better patient compliance.Keywords: levofloxacin, community-acquired pneumonia, pharmacodynamics, resistance, pharmacokinetics, clinical use

    An increasing number of children infected by enterovirus D68 (EV-D68) and affected by severe respiratory illness, muscle weakness and paralysis were described in the USA and Canada in 2014 OBJECTIVES: To investigate the potential involvement of EV-D68 in determining community-acquired pneumonia (CAP) in hospitalised children in order to acquire information concerning the clinical problems associated with EV-D68 in Italy. This prospective study of children hospitalised for CAP in the largest Pediatric Department in Milan, Italy, was carried out between 1 June and 31 December 2014. All of the children's admission nasopharyngeal swabs were investigated for the presence of EV-D68. One hundred and seventy-six children with radiographically confirmed CAP were hospitalised during the 7-month study period: 97 (55.1%) had enterovirus/rhinovirus-positive nasopharyngeal samples, including four (2.3%) positive for EV-D68. These four samples were collected between 9 and 21 October, a month in which 21 cases of CAP were recorded. Phylogenetic analysis showed that all of the sequences fell into clade B. The most severe case was diagnosed in a 14-year-old girl with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS syndrome), who died after 12 days of hospitalisation. EV-D68 was detected in few children with usually mild-to-moderate lower respiratory tract infection, although the disease lead to the death of a girl with a severe chronic underlying disease. Further studies capable of better defining the epidemiological, genetic and pathogenetic characteristics of the virus are required in order to be able to prepare appropriate preventive and therapeutic measures.

    2015-10-01

    Community-acquired pneumonia (CAP) is still an important and serious disease for elderly and geriatric patients. For epidemiological and clinical reasons it is important to collate the frequencies of the various degrees of severity of CAP and to obtain information on the spread and degree of the threat to the various risk groups by CAP. In outpatient treatment a simple to execute prognosis score can be used to objectify the assessment of the clinical status of a patient and to support therapeutic decision-making. For this purpose knowledge of the appropriate instruments should be available to potential users. Since the 1990s a variety of risk scores for stratification of CAP have been developed and evaluated. This article presents the content and value of the available risk scores whereby the advantages and disadvantages of the individual scores are critically compared. Special emphasis is placed on the importance of the risk scores for geriatric patients. At present the decision about outpatient or inpatient treatment is primarily based on the risk score CRB-65. Criteria for intensive care unit admissions are provided by the modified American Thoracic Society (ATS) set of criteria. Overall, risk scores are less reliable for elderly patients than for younger adults. For treatment decisions for the elderly, functional aspects should also be considered in addition to the aspects of risk scores discussed here. In particular, the decision about inpatient admission for elderly, geriatric CAP patients should be made on an individual basis taking the benefit-risk relationship into consideration.

    Highlights: • Patients with H1N1 pneumonia demonstrated more opacified zones on chest x-ray than patients with non-H1N1 pneumonias. • A particular ‘phenotype’ of chest x-ray changes was identified in H1N1 patients. • This H1N1 ‘phenotype’ was the same for the two evaluated ‘flu seasons, during both pandemic and post pandemic stages. - Abstract: Aims: To review, phenotype and assess potential prognostic value of initial chest X-ray findings in patients with H1N1 influenza during seasonal outbreaks of 2009 and 2010, in comparison with non-H1N1, community acquired pneumonia (CAP). Methods: We retrospectively identified 72 patients admitted to hospital with pneumonia during the seasons of 2009 and 2010. H1N1 cases were confirmed by virology PCR. Presenting chest X-rays were jointly read by 2 radiologists, who were ‘blinded’ to further patient details and divided into 6 zones. Total number of opacified zones, the pattern and distribution of changes and length of hospital stay were recorded. Results: Patients with H1N1 demonstrated more opacified zones (mean of 2.9 compared with 2.0; p = 0.006), which were bilateral in two-thirds compared with a quarter of those with non-H1N1 CAP (p = 0.001). H1N1 radiographs were more likely to be ‘patchy’ versus ‘confluent’ changes of non-H1N1 CAP (p = 0.03) and more often demonstrated peripheral distribution (p = 0.01). H1N1 patients tended to stay in hospital longer (not significant; p = 0.08). A positive correlation existed between number of affected zones and length of inpatient stay, which was statistically significant for the cohorts combined (p = 0.02). The findings were the same for the two evaluated seasons. Conclusion: H1N1 patients demonstrated more extensive disease, which was more likely bilateral, ‘patchy’, and peripheral in distribution. With increasing global cases of H1N1, knowledge of the typical findings of the H1N1 presenting chest X-ray may assist with early triage of patients

    Highlights: • Patients with H1N1 pneumonia demonstrated more opacified zones on chest x-ray than patients with non-H1N1 pneumonias. • A particular ‘phenotype’ of chest x-ray changes was identified in H1N1 patients. • This H1N1 ‘phenotype’ was the same for the two evaluated ‘flu seasons, during both pandemic and post pandemic stages. - Abstract: Aims: To review, phenotype and assess potential prognostic value of initial chest X-ray findings in patients with H1N1 influenza during seasonal outbreaks of 2009 and 2010, in comparison with non-H1N1, community acquired pneumonia (CAP). Methods: We retrospectively identified 72 patients admitted to hospital with pneumonia during the seasons of 2009 and 2010. H1N1 cases were confirmed by virology PCR. Presenting chest X-rays were jointly read by 2 radiologists, who were ‘blinded’ to further patient details and divided into 6 zones. Total number of opacified zones, the pattern and distribution of changes and length of hospital stay were recorded. Results: Patients with H1N1 demonstrated more opacified zones (mean of 2.9 compared with 2.0; p = 0.006), which were bilateral in two-thirds compared with a quarter of those with non-H1N1 CAP (p = 0.001). H1N1 radiographs were more likely to be ‘patchy’ versus ‘confluent’ changes of non-H1N1 CAP (p = 0.03) and more often demonstrated peripheral distribution (p = 0.01). H1N1 patients tended to stay in hospital longer (not significant; p = 0.08). A positive correlation existed between number of affected zones and length of inpatient stay, which was statistically significant for the cohorts combined (p = 0.02). The findings were the same for the two evaluated seasons. Conclusion: H1N1 patients demonstrated more extensive disease, which was more likely bilateral, ‘patchy’, and peripheral in distribution. With increasing global cases of H1N1, knowledge of the typical findings of the H1N1 presenting chest X-ray may assist with early triage of patients

    Community acquired pneumonia in children remains an important cause of childhood deaths throughout the world that can be prevented by the use of antibiotics and access to medical care. Both were reduced in 2001 when Argentina suffered a severe social crisis. Among the responses to the crisis, the Remediar Program provided free essential medicines to the socially vulnerable population. Assess the health impact and costs of the provision of free medicines at the first level of public attention for childhood pneumonia. Three designs: 1. Ecological study with cross comparisons of diagnoses, prescriptions, beneficiaries by individual provinces of Remediar forms. children under 15 years old attended at 6 thousand health centres in Argentina, encompassing 24 Argentine provinces from March 2005 until February 2006. 2. Counterfactual approach. 3. Calculation of drug costs per unit of outcome. Over 15 million prescriptions were identified, 2,420 children under 1 year, 19,205 of 1 to 4 years and 15,977 from 5 to 14 years old with pneumonia. 90% of beneficiaries received antibiotics, most often amoxicillin. In children's under 5 years of age, Remediar coverage was 27.8%, with greater impact in the poorest provinces. The likely impact was 4,322 lives saved or 310,325 years of life lost avoided if mortality without antibiotics was 20%. Indigents who had children with pneumonia saved by medicines 14.3% of their income. Each life saved could have cost US $ 6.46 and each year of life lost averted US $ 0.09. This work highlights the impact of a low-cost health program for the treatment of vulnerable populations with childhood pneumonia in Argentina.

    Full Text Available Abstract Background Adults with certain comorbid conditions have a higher risk of pneumonia than the overall population. If treatment of pneumonia is more costly in certain predictable situations, this would affect the value proposition of populations for pneumonia prevention. We estimate the economic impact of community-acquired pneumonia (CAP for adults with asthma, diabetes, chronic obstructive pulmonary disease (COPD and congestive heart failure (CHF in a large U.S. commercially-insured working age population. Methods Data sources consisted of 2003 through 2007 Thomson Reuters MarketScan Commercial Claims and Encounters and Thomson Reuters Health Productivity and Management (HPM databases. Pneumonia episodes and selected comorbidities were identified by ICD-9-CM diagnosis codes. By propensity score matching, controls were identified for pneumonia patients. Excess direct medical costs and excess productivity cost were estimated by generalized linear models (GLM. Results We identified 402,831 patients with CAP between 2003 through 2007, with 25,560, 32,677, 16,343, and 5,062 episodes occurring in patients with asthma, diabetes, COPD and CHF, respectively. Mean excess costs (and standard error, SE of CAP were $14,429 (SE=44 overall. Mean excess costs by comorbidity subgroup were lowest for asthma ($13,307 (SE=123, followed by diabetes ($21,395 (SE=171 and COPD ($23,493 (SE=197; mean excess costs were highest for patients with CHF ($34,436 (SE=549. On average, indirect costs comprised 21% of total excess costs, ranging from 8% for CHF patients to 27% for COPD patients. Conclusions Compared to patients without asthma, diabetes, COPD, or CHF, the excess cost of CAP is nearly twice as high for patients with diabetes and COPD and nearly three times as high for patients with CHF. Indirect costs made up a significant but varying portion of excess CAP costs. Returns on prevention of pneumonia would therefore be higher in adults with these comorbidities.

    Between all patients treated in the Emergency Department (ED), 1.35% are diagnosed with community-acquired pneumonia (CAP). CAP is the main cause of death due to infectious disease (10-14%) and the most frequent reason of sepsis-septic shock in the ED. In the last decade, the search for objective tools to help establishing an early diagnosis, bacterial aetiology, severity, suspicion of bacteremia and the prognosis of mortality has increased. Biomarkers have shown their usefulness in this matter. Procalcitonin (obtains the highest accuracy for CAP diagnosis, bacterial aetiology and the presence of bacteremia), lactate (biomarker of hypoxia and tissue hypoperfusion) and proadrenomedullin (which has the greatest accuracy to predict mortality which in combination with the prognostic severity scales obtains even better results). The aim of this review is to highlight recently published scientific evidence and to compare the utility and prognostic accuracy of the biomarkers in CAP patients treated in the ED.

    Community acquired pneumonia is a major global public health problem. In the Netherlands there are 40,000-50,000 hospital admissions for pneumonia per year. In the large majority of these hospital admissions the etiologic agent is not determined and a real-time surveillance system is lacking. Localised and temporal increases in hospital admissions for pneumonia are therefore only detected retrospectively and the etiologic agents remain unknown. Here, we perform spatio-temporal analyses of pneumonia hospital admission data in the Netherlands. To this end, we scanned for spatial clusters on yearly and seasonal basis, and applied wavelet cluster analysis on the time series of five main regions. The pneumonia hospital admissions show strong clustering in space and time superimposed on a regular yearly cycle with high incidence in winter and low incidence in summer. Cluster analysis reveals a heterogeneous pattern, with most significant clusters occurring in the western, highly urbanised, and in the eastern, intensively farmed, part of the Netherlands. Quantitatively, the relative risk (RR) of the significant clusters for the age-standardised incidence varies from a minimum of 1.2 to a maximum of 2.2. We discuss possible underlying causes for the patterns observed, such as variations in air pollution.

    Klebsiella pneumoniae is now recognized as an urgent threat to human health because of the emergence of multidrug-resistant strains associated with hospital outbreaks and hypervirulent strains associated with severe community-acquired infections. K. pneumoniae is ubiquitous in the environment and can colonize and infect both plants and animals. However, little is known about the population structure of K. pneumoniae, so it is difficult to recognize or understand the emergence of clinically important clones within this highly genetically diverse species. Here we present a detailed genomic framework for K. pneumoniae based on whole-genome sequencing of more than 300 human and animal isolates spanning four continents. Our data provide genome-wide support for the splitting of K. pneumoniae into three distinct species, KpI (K. pneumoniae), KpII (K. quasipneumoniae), and KpIII (K. variicola). Further, for K. pneumoniae (KpI), the entity most frequently associated with human infection, we show the existence of >150 deeply branching lineages including numerous multidrug-resistant or hypervirulent clones. We show K. pneumoniae has a large accessory genome approaching 30,000 protein-coding genes, including a number of virulence functions that are significantly associated with invasive community-acquired disease in humans. In our dataset, antimicrobial resistance genes were common among human carriage isolates and hospital-acquired infections, which generally lacked the genes associated with invasive disease. The convergence of virulence and resistance genes potentially could lead to the emergence of untreatable invasive K. pneumoniae infections; our data provide the whole-genome framework against which to track the emergence of such threats.

    Full Text Available Klebsiella spp. isolates from community-acquired infections were characterized. A total of 39 Klebsiella spp. isolates were obtained from outpatients at four rural hospitals in Mexico (2013–2014. The biochemical tests identified all as being K. pneumoniae. The molecular multiplex-PCR test identified 36 (92.4% K. pneumoniae isolates and one (2.5% K. variicola isolate, and phylogenetic analysis of the rpoB gene identified two isolates (5.1% belonging to K. quasipneumoniae subsp. quasipneumoniae and K. quasivariicola. The last one was confirmed by phylogenetic analysis of six-loci concatenated genes. Mostly the isolates were multidrug resistant; however, a minority were extended-spectrum β-lactamase producing (10.2%. The extended-spectrum β-lactamase CTX-M-15 gene was identified in these isolates. Analysis of biofilm production and the hypermucoviscosity phenotype showed a total of 35 (92.3% and seven (17.9% of the isolates were positive for these phenotypes respectively. The K2 (4/39, 10.2%, K5 (2/39, 5.1% and K54 (1/39, 2.5% serotypes were identified in seven (17.9% of the isolates, and only 28.5% (2/7 hypermucoviscous isolates were positive for the K2 and K5 serotypes. In general, the sequence type (ST analysis and phylogenetic analysis of seven multilocus sequence typing loci were heterogeneous; however, ST29 was the most prevalent ST in the analysed isolates, accounting for 19% (4/21 of the total isolates. Two of the four ST29 isolates had the hypermucoviscosity phenotype. The virulence factors for fimbriae were the most prevalent, followed by siderophores. Community-acquired infections are caused by various species from Klebsiella genus, with different profiles of antibiotic resistance and heterogeneous virulence factors.

In vitro studies indicate that JNJ-Q2 has potent activity against pathogens responsible for acute bacterial skin and skin structure infections (ABSSSI and community-acquired bacterial pneumonia (CABP, such as Staphylococcus aureus and Streptococcus pneumoniae. JNJ-Q2 also has been shown to have a higher barrier to resistance compared to other agents in the class and it remains highly active against drug-resistant organisms, including methicillin-resistant S. aureus, ciprofloxacin-resistant methicillin-resistant S. aureus, and drug-resistant S. pneumoniae. In two Phase II studies, the efficacy of JNJ-Q2 was comparable to linezolid for ABSSSI and moxifloxacin for CABP. Furthermore, JNJ-Q2 was well tolerated, with adverse event rates similar to or less than other fluoroquinolones. With an expanded spectrum of activity and low potential for resistance, JNJ-Q2 shows promise as an effective treatment option for ABSSSI and CABP. Considering its early stage of development, the definitive role of JNJ-Q2 against these infections and its safety profile will be determined in future Phase III studies.

    Hospital-acquired and ventilator-associated bacterial pneumonia (HABP/VABP) are among the most prevalent infections in hospitalized patients, particularly those in the intensive care unit. Importantly, the frequency of multidrug resistant (MDR) Gram-negative (GN) bacteria as the bacteriologic cause of HABP/VABP is increasing. These include MDR Pseudomonas aeruginosa, Acinetobacter baumannii, and carbapenem resistant Enterobacteriaceae (CRE). Few antibiotics are currently available when such MDR Gram-negatives are encountered and older agents such as polymyxin B, colistin (polymyxin E), and tigecycline have typically performed poorly in HABP/VABP. Areas covered: In this review, the authors summarize novel antibiotics which have reached phase 3 clinical trials including patients with HABP/VABP. For each agent, the spectrum of activity, pertinent pharmacological characteristics, clinical trial data, and potential utility in the treatment of MDR-GN HABP/VABP is discussed. Expert opinion: Novel antibiotics currently available, and those soon to be, will expand opportunities to treat HABP/VABP caused by MDR-GN organisms and minimize the use of more toxic, less effective drugs. However, with sparse clinical data available, defining the appropriate role for each of the new agents is challenging. In order to maximize the utility of these antibiotics, combination therapy and the role of therapeutic drug monitoring should be investigated.

    The most recent European guidelines and task force reports on hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) were published almost 10 years ago. Since then, further randomised clinical trials of HAP and VAP have been conducted and new information has become available. Studies of epidemiology, diagnosis, empiric treatment, response to treatment, new antibiotics or new forms of antibiotic administration and disease prevention have changed old paradigms. In addition, important differences between approaches in Europe and the USA have become apparent.The European Respiratory Society launched a project to develop new international guidelines for HAP and VAP. Other European societies, including the European Society of Intensive Care Medicine and the European Society of Clinical Microbiology and Infectious Diseases, were invited to participate and appointed their representatives. The Latin American Thoracic Association was also invited.A total of 15 experts and two methodologists made up the panel. Three experts from the USA were also invited (Michael S. Niederman, Marin Kollef and Richard Wunderink).Applying the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) methodology, the panel selected seven PICO (population-intervention-comparison-outcome) questions that generated a series of recommendations for HAP/VAP diagnosis, treatment and prevention.

    The aim of this study is to evaluate the effectiveness of a hospital-based pneumonia nurse navigator program. This study used a retrospective, formative evaluation. Data of patients admitted from January 2012 through December 2014 to a large community hospital with a primary or secondary diagnosis of pneumonia, excluding aspiration pneumonia, were used. Data included patient demographics, diagnoses, insurance coverage, core measures, average length of stay (ALOS), disposition, readmission rate, financial outcomes, and patient barriers to care were collected. Descriptive statistics and parametric testing were used to analyze data. Core measure performance was sustained at the 90th percentile 2 years after the implementation of the navigator program. The ALOS did not decrease to established benchmarks; however, the SD for ALOS decreased by nearly half after implementation of the navigator program, suggesting the program decreased the number and length of extended stays. Charges per case decreased by 21% from 2012 to 2014. Variable costs decreased by 4% over a 2-year period, which increased net profit per case by 5%. Average readmission payments increased by 8% from 2012 to 2014, and the net revenue per case increased by 8.3%. The pneumonia nurse navigator program may improve core measures, reduce ALOS, and increase net revenue. Future evaluations are necessary to substantiate these findings and optimize the cost and quality performance of navigator programs.

    Klebsiella pneumoniae is one of the most important agents of community-acquired urinary tract infection (CA-UTI). In addition to extended-spectrum β-lactamases (ESBLs), a number of virulence factors have been shown to play an important role in the pathogenesis of K. pneumoniae, including capsule, siderophores, and adhesins. Little is known about the genetic diversity and virulence content of the CTX-M-15-producing K. pneumoniae isolated from CA-UTI in Iran. A total of 152 K. pneumoniae isolates were collected from CA-UTI patients in Tehran from September 2015 through April 2016. Out of 152 isolates, 40 (26.3%) carried bla CTX-M-15 . PCR was performed for detection of virulence genes in CTX-M-15-producing isolates. Furthermore, all of these isolates were subjected to multiple-locus variable-number of tandem repeat (VNTR) analysis (MLVA). Using MLVA method, 36 types were identified. CTX-M-15-producing K. pneumoniae isolates were grouped into 5 clonal complexes (CCs). Of these isolates, mrkD was the most prevalent virulence gene (95%), followed by kpn (60%), rmpA (37.5%), irp (35%), and magA (2.5%). No correlation between MLVA types or CCs and virulence genes or antibiotic resistance patterns was observed. Overall, it is thought that CTX-M-15-producing K. pneumoniae strains isolated from CA-UTI have arisen from different clones. Copyright © 2016 Elsevier Ltd. All rights reserved.

    This study was to investigate the diagnostic value of serum procalcitonin(PCT) in identifying the etiology of non-responding community-acquired pneumonia (CAP) after initial antibiotic therapy. A retrospective analysis was performed for 232 hospitalized CAP patients admitted to the People's Hospital of Zhengzhou University during June 2013 and January 2014. Early treatment failure was defined as the presence of persistent fever (>38 °C) and/or clinical symptoms (malaise, cough, expectoration, dyspnea) or deterioration after at least 72 h of initial antimicrobial treatment, or development of respiratory failure requiring mechanical ventilation, or septic shock. Bronchoscopy or transthoracic lung biopsy was performed in case of early treatment failure when indicated. Serum level of PCT was detected by double antibody sandwich method. The differences between 2 or more groups were compared using 2-independent student t test, one-way ANOVA; Mann-Whitney U test, Kruskal-Wallis rank sum test, or χ(2) test. Risk factors and odds ratios for nonresponsiveness were analyzed by setting up a Logistic regression model. The diagnostic values of PCT were determined by receiver operating characteristic curves (ROC curves). Of the 232 CAP patients enrolled, 124 were male and 108 were female, with an average age of (46 ± 20) years. Thirty-six patients failed to respond to the initial antibiotic therapy. As shown by Logistic regression analysis, the risk factors for treatment failure included hypoalbuminemia, type 2 diabetes, previous history of splenectomy , PSI 4-5 grade, and lung infiltration ≥ 3 lobes. The most common causes of non-responsiveness were antimicrobial insufficiency (n = 23), and misdiagnosis of noninfectious mimics of pneumonia (n = 11), with 2 cases of unidentified etiology. The serum PCT level in admission was 0.19 (0.07-0.66) µg/L in the antimicrobial insufficiency subgroup, which was significantly higher than that in the misdiagnosis subgroup [0

It has been revealed that S. pneumoniae is the primary pathogen in the structure of nasopharyngeal carriage in the children under 5 years of age hospitalized with acute bacterial infections, and the primary bacterial causative agent of acute otitis media at this age. Nasopharyngeal pneumococcal carriage analysis revealed the prevalent serotypes — 19F, 14, 23F, 3, 6A and B; they were present in 3/4 of all cases; 19F was the most frequent (> 20%. Diversity of the S. pneumoniae serotypes detected in middle ear liquid was less significant — 17 serotypes (in comparison with 24 serotypes in nasopharynx. The 5 prevalent serotypes were 19F, 3, 14, 23F, 6B and 19A (> 75% in tote. Detection rate of serotypes 3 and 19A in middle ear liquid significantly exceeded the detection rate of these serotypes in case of nasopharyngeal carriage. The study of invasive infections revealed serotypes 14, 23F, 3 and 15C. These data may be used as a benchmark for future monitoring and evaluation of effect of PCV vaccines on epidemiology of

    Adult community-acquired pneumonia (CAP) is a common cause of morbidity and mortality which is managed by different disciplines in a heterogeneous fashion. Development of consensus guidelines to standardize these wide variations in care has become a prime objective. The Lebanese Society of Infectious Diseases and Clinical Microbiology (LSIDCM) convened to set Lebanese national guidelines for the management of CAP since it is a major and a prevalent disease affecting the Lebanese population. These guidelines, besides being helpful in direct clinical practice, play a major role in establishing stewardship programs in hospitals in an effort to contain antimicrobial resistance on the national level. These guidelines are intended for primary care practitioners and emergency medicine physicians. They constitute an appropriate starting point for specialists' consultation being based on the available local epidemiological and resistance data. This document includes the following: 1/ Rationale and scope of the guidelines; 2/ Microbiology of CAP based on Lebanese data; 3/ Clinical presentation and diagnostic workup of CAP; 4/ Management and prevention strategies based on the IDSA/ATS Consensus Guidelines, 2007, and the ESCMID Guidelines, 2011, and tailored to the microbiological data in Lebanon; 5/ Comparison to regional guidelines. The recommendations made in this document were graded based on the strength of the evidence as in the 2007 IDSA/ATS Consensus Guidelines. Hopefully, these guidelines will be an important step towards standardization of CAP care in Lebanon and set the agenda for further research in this area.

    Community-acquired pneumonia (CAP) is a leading cause of death from an infectious cause worldwide. Guideline-concordant antibiotic therapy initiated in a timely manner is associated with improved treatment responses and patient outcomes. In the post-antibiotic era, much of the morbidity and mortality of CAP is as a result of the interaction between bacterial virulence factors and host immune responses. In patients with severe CAP, or who are critically ill, there is a lot of emerging observational evidence demonstrating improved survival rates when treatment using combination therapy with a β-lactam and a macrolide is initiated, as compared to other antibiotic regimes without a macrolide. Macrolides in combination with a β-lactam antibiotic provide broader coverage for the atypical organisms implicated in CAP, and may contribute to antibacterial synergism. However, it has been postulated that the documented immunomodulatory effects of macrolides are the primary mechanism for improved patient outcomes through attenuation of bacterial virulence factors and host systemic inflammatory responses. Despite concerns regarding the limitations of observational evidence and the lack of confirmatory randomized controlled trials, the potential magnitude of mortality benefits estimated at 20-50% cannot be overlooked. In light of recent data from a number of trials showing that combination treatment with a macrolide and a suitable second agent is justified in all patients with severe CAP, such treatment should be obligatory for those admitted to an intensive care setting.

    Patients with nursing home acquired pneumonia (NHAP) present a distinct group of lower respiratory track infections with different risk factors, clinical presentation, and mortality rates. To evaluate the diagnostic value of clinical pulmonary infection score (CPIS), C-reactive protein, and procalcitonin and to compare the accuracy of pneumonia severity scores (confusion, urea nitrogen, breathing frequency, blood pressure, ≥ 65 y of age [CURB-65]; pneumonia severity index; NHAP index; systolic blood pressure, multilobar involvement, albumin, breathing frequency, tachycardia, confusion, oxygen, arterial pH [SMART-COP]; and systolic blood pressure, oxygen, age > 65 y, breathing frequency [SOAR]) in predicting in-patient mortality from NHAP. Nursing home residents admitted to the hospital with acute respiratory illness were enrolled in the study. Subjects were classified as having NHAP (Group A) or other pulmonary disorders (Group B). Clinical, imaging, and laboratory data were assessed to compute CPIS and severity scores. C-reactive protein and procalcitonin were measured by immunonephelometry and immunoassay, respectively. Fifty-eight subjects were diagnosed with NHAP (Group A) and 29 with other pulmonary disorders (Group B). The mean C-reactive protein ± SD was 16.38 ± 8.6 mg/dL in Group A and 5.2 ± 5.6 mg/dL in Group B (P 1.1 ng/mL was an independent predictor of in-patient mortality. Of the pneumonia severity scores, CURB-65 showed greater accuracy in predicting in-patient mortality (area under the curve of 0.68, 95% CI 0.53-0.84, P = .06). CPIS, procalcitonin, and C-reactive protein are reliable for the diagnosis of NHAP. Procalcitonin and CURB-65 are accurate in predicting in-patient mortality in NHAP.

    Community-acquired pneumonia (CAP) is a major cause of morbidity and mortality in adults. The annual incidence of CAP in adults in Spain ranges from 3 to 14 cases per 1,000 inhabitants. Current clinical guidelines primarily focus on the therapeutic approach to CAP rather than its prevention. The aim of this study is to develop and propose a practical guide for CAP prevention through vaccination in Spain according to available vaccines and evidence. A literature review and expert opinion. Pneumococcal and influenza vaccines are the main preventive tools available against CAP. Age, chronic diseases, and immunosuppression are risk factors for pneumonia, so these populations should be a priority for vaccination. In addition, influenza and pneumococcal vaccination is considered advisable in healthy adults under 60 years of age, and anyone with risk condition for CAP, irrespective of age. The influenza vaccine will be administered seasonally, while pneumococcal vaccination can be administered at any time of the year. Vaccination against pneumococcus and influenza in adults can help to reduce the burden of CAP and its associated complications. The available evidence supports the priority indications set out in this guide, and it would be advisable to try to achieve a wide circulation and practical implementation of these recommendations.

    Cefixime is an oral third generation cephalosporin, frequently used in respiratory tract infections (RTI) in the pediatric population. However, in some publications cefixime has demonstrated poor efficacy against staphylococci and streptococci. of this study was to evaluate the efficacy of cefixime in the treatment of community-acquired infections in a country where parenteral third generation cephalosporins have been used for a long time. The present study was designed to assess the clinical efficacy, bacteriological eradication rates and tolerability of cefixime in children with community-acquired upper RTI (URTI), lower RTI (LRTI) and uncomplicated urinary tract infections (UTI). The study was prospective, open, and included 89 patients, from 6 months to 28 years, of both sexes, with the diagnosis of community-acquired URTI, LRTI and UTI. The treatment with cefixime was successful in 30/30 (100%) patients suffering from acute otitis media (AOM), in 10/12 (83.3%) with acute sinusitis, in 12/12 patients (100%) with pneumonia, in 31/35 (88.57) with uncomplicated UTI. The antibiotic was well tolerated. In 10 days treatment we recorded one case (1.3%) with acute gastroenteritis and two cases (2.6%) of maculopapular rash. Side-effects were transient and disappeared after finishing therapy in all three of the cases. Community-acquired infections, such as AOM, LRTI and UTI, caused by susceptible pathogens, can be treated with cefixime, as a good choice for a successful clinical response.

    To determine trends, mortality rates, and costs of antimicrobial resistance in invasive bacterial infections in hospitalized children, we analyzed data from Angkor Hospital for Children, Siem Reap, Cambodia, for 2007-2016. A total of 39,050 cultures yielded 1,341 target pathogens. Resistance rates were high; 82% each of Escherichia coli and Klebsiella pneumoniae isolates were multidrug resistant. Hospital-acquired isolates were more often resistant than community-acquired isolates; resistance trends over time were heterogeneous. K. pneumoniae isolates from neonates were more likely than those from nonneonates to be resistant to ampicillin-gentamicin and third-generation cephalosporins. In patients with community-acquired gram-negative bacteremia, third-generation cephalosporin resistance was associated with increased mortality rates, increased intensive care unit admissions, and 2.26-fold increased healthcare costs among survivors. High antimicrobial resistance in this setting is a threat to human life and the economy. In similar low-resource settings, our methods could be reproduced as a robust surveillance model for antimicrobial resistance.

    Full Text Available Abstract Background The ideal method to encourage uptake of clinical guidelines in hospitals is not known. Several strategies have been suggested. This study evaluates the impact of academic detailing and a computerised decision support system (CDSS on clinicians' prescribing behaviour for patients with community acquired pneumonia (CAP. Methods The management of all patients presenting to the emergency department over three successive time periods was evaluated; the baseline, academic detailing and CDSS periods. The rate of empiric antibiotic prescribing that was concordant with recommendations was studied over time comparing pre and post periods and using an interrupted time series analysis. Results The odds ratio for concordant therapy in the academic detailing period, after adjustment for age, illness severity and suspicion of aspiration, compared with the baseline period was OR = 2.79 [1.88, 4.14], p Conclusion Deployment of a computerised decision support system was associated with an early improvement in antibiotic prescribing practices which was greater than the changes seen with academic detailing. The sustainability of this intervention requires further evaluation.

    Full Text Available Vietnam is a lower middle-income country with no national surveillance system for hospital-acquired infections (HAIs. We assessed the prevalence of hospital-acquired infections and antimicrobial use in adult intensive care units (ICUs across Vietnam.Monthly repeated point prevalence surveys were systematically conducted to assess HAI prevalence and antimicrobial use in 15 adult ICUs across Vietnam. Adults admitted to participating ICUs before 08:00 a.m. on the survey day were included.Among 3287 patients enrolled, the HAI prevalence was 29.5% (965/3266 patients, 21 missing. Pneumonia accounted for 79.4% (804/1012 of HAIs Most HAIs (84.5% [855/1012] were acquired in the survey hospital with 42.5% (363/855 acquired prior to ICU admission and 57.5% (492/855 developed during ICU admission. In multivariate analysis, the strongest risk factors for HAI acquired in ICU were: intubation (OR 2.76, urinary catheter (OR 2.12, no involvement of a family member in patient care (OR 1.94, and surgery after admission (OR 1.66. 726 bacterial isolates were cultured from 622/1012 HAIs, most frequently Acinetobacter baumannii (177/726 [24.4%], Pseudomonas aeruginosa (100/726 [13.8%], and Klebsiella pneumoniae (84/726 [11.6%], with carbapenem resistance rates of 89.2%, 55.7%, and 14.9% respectively. Antimicrobials were prescribed for 84.8% (2787/3287 patients, with 73.7% of patients receiving two or more. The most common antimicrobial groups were third generation cephalosporins, fluoroquinolones, and carbapenems (20.1%, 19.4%, and 14.1% of total antimicrobials, respectively.A high prevalence of HAIs was observed, mainly caused by Gram-negative bacteria with high carbapenem resistance rates. This in combination with a high rate of antimicrobial use illustrates the urgent need to improve rational antimicrobial use and infection control efforts.

    Full Text Available Despite the fact that the influenza virus pathogenicity factors have been well studied in vitro, in vivo lack is presented in understanding of the those risk factors, objective and laboratory parameters, which related most of all to the fatal virus-associated community-aquired pneumonia (CAP. That is why the purpose of the study was to study the clinical and laboratory characteristics of patients with severe virus-associated CAP during the 2015–2016 influenza epidemic and their role as predictors of patients’ mortality. To do this, patients with severe virus-associated CAP were examined. They were divided into 2 groups depending on the outcome of treatment: 1st- deaths from the virus-associated severe CAP and 2nd - patients with successful treatment of the severe virus-associated CAP. Special statistical method was used – one-dimensional analysis of variance to compare individual parameters between the two groups of patients (surviving and deceased. Pearson χ2 test (contingency table was used for categorical variables. Factors that were significant predictors of mortality as a result of univariate analysis were tested using multifactorial analysis using logistic regression. In the final model, each parameter must have had a significant impact on mortality. It was found that risk factors for death in patients with severe virus-associated CAP according to univariate analysis were: presence of obesity, disorders of consciousness, BH≥35 min, SaO2<80%, PaO2<50 mm Hg, mmHg PaCO2 ≥50 mmHg during hospitalization. Independent predictors of mortality according to the logistic regression are the presence of obesity, disorders of consciousness, PaO2<50 mm Hg, mmHg PaCO2 ≥50 mmHg. Given that among clinical and laboratory parameters key parameters that significantly influence the outcome, are indicators of the severity of hypoxia and hypoxemia, a major step in determining the severity of the patients with virus-associated severe emergency is

    Pneumonia which develops in patients while living in their own home is categorized as community-acquired pneumonia (CAP), even if these patients are bedridden and receiving home health care. However, because of the differences in patient backgrounds, we speculated that the clinical outcomes and pathogens of bedridden patients with pneumonia who are receiving home health care would be different from those of CAP. We conducted a prospective study of patients with CAP who were hospitalized at our hospital from April 2007 through September 2009. We compared home health care bedridden pneumonia (performance status 4, PS4-CAP) with non-PS4-CAP in a total of 505 enrolled patients in this study. Among these, 66 had PS4-CAP, mostly associated with aspiration. Severity scores, mortality rate, recurrence rate and length of hospital stay of those with PS4-CAP were significantly higher than those with non-PS4-CAP. Drug resistant pathogens were more frequently isolated from patients with PS4-CAP than from those of non-PS4-CAP. The results of patients with PS4-CAP were in agreement with those of previous health care-associated pneumonia (HCAP) reports. The present study suggested home health care bedridden pneumonia should be categorized as HCAP, not CAP.

    Objective In the era of powerful immunosuppression, opportunistic infections are an increasing concern in systemic lupus erythematosus. One of the best-studied opportunistic infections is Pneumocystis pneumonia; however, the prevalence of Pneumocystis pneumonia in systemic lupus erythematosus is not clearly defined. This study evaluates the prevalence of Pneumocystis pneumonia in hospitalized systemic lupus erythematosus patients, with a focus on validating the Pneumocystis pneumonia and systemic lupus erythematosus diagnoses with clinical information. Methods This retrospective cohort study evaluates the prevalence of Pneumocystis pneumonia in all systemic lupus erythematosus patients treated at Columbia University Medical Center-New York Presbyterian Hospital between January 2000 and September 2014, using electronic medical record data. Patients with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and patients with renal transplants (including both early and late post-transplant patients) represented immunocompromised control groups. Patients with systemic lupus erythematosus, Pneumocystis pneumonia, HIV/AIDS, or renal transplant were identified using diagnostic codes from the International Classification of Diseases, Ninth Revision (ICD-9). Results Out of 2013 hospitalized systemic lupus erythematosus patients, nine had presumed Pneumocystis pneumonia, yielding a low prevalence of Pneumocystis pneumonia in systemic lupus erythematosus of 0.45%. Three of the nine Pneumocystis pneumonia cases were patients with concomitant systemic lupus erythematosus and HIV/AIDS. Only one of these nine cases was histologically confirmed as Pneumocystis pneumonia, in a patient with concomitant systemic lupus erythematosus and HIV/AIDS and a CD4 count of 13 cells/mm 3 . The prevalence of Pneumocystis pneumonia in renal transplant patients and HIV/AIDS patients was 0.61% and 5.98%, respectively. Conclusion Given the reported high rate of adverse effects

    Etienne Ruppé

    2017-11-01

    Full Text Available Clinical metagenomics (CMg, referred to as the application of next-generation sequencing (NGS to clinical samples, is a promising tool for the diagnosis of hospital-acquired pneumonia (HAP. Indeed, CMg allows identifying pathogens and antibiotic resistance genes (ARGs, thereby providing the information required for the optimization of the antibiotic regimen. Hence, provided that CMg would be faster than conventional culture, the probabilistic regimen used in HAP could be tailored faster, which should lead to an expected decrease of mortality and morbidity. While the inference of the antibiotic susceptibility testing from metagenomic or even genomic data is challenging, a limited number of antibiotics are used in the probabilistic regimen of HAP (namely beta-lactams, aminoglycosides, fluoroquinolones, glycopeptides and oxazolidinones. Accordingly, based on the perspective of applying CMg to the early diagnostic of HAP, we aimed at reviewing the performances of whole genomic sequencing (WGS of the main HAP-causing bacteria (Enterobacteriaceae, Pseudomonas aeruginosa, Acinetobacter baumannii, Stenotrophomonas maltophilia and Staphylococcus aureus for the prediction of susceptibility to the antibiotic families advocated in the probabilistic regimen of HAP.

  10. Spatial Analysis of Potentially Preventable Pneumonia and Asthma Hospitalizations for Children in the Texas Coastal Bend Area

    Science.gov (United States)

    Lin, Na

    Pneumonia and asthma, two common Ambulatory Care Sensitive Conditions (ACSCs), were two top reasons for the admission of children to the hospitals and emergency rooms in the United States in 2011. Pneumonia and asthma are potentially preventable if the child's environment is properly managed. Underlying vulnerabilities such as low socioeconomic status (SES) and proximity to air pollution play an important role in ACSCs hospitalization. Pneumonia and asthma are two common reasons for hospitalizations among children and missed school days in Texas Coastal Bend Area. This thesis examines the relationships between neighborhood socioeconomic characteristics, meteorological conditions and children ACSCs hospitalization, including pneumonia and asthma among children age 0-17 in this area. Hospital discharge data from 2007 to 2009 based on Zip Code Tabulation Area (ZCTA) were examined along with American Community Survey (ACS) data, air pollution data from Environmental Protection Agency (EPA) and temperature data from National Climatic Data Center (NCDC). Hotspot and Local Moran's I analyses were applied to identify the concentrations of the illnesses. Two regressions (OLS and GWR) were applied to identify factors that contribute the most to ACSCs hospitalization. Pearson's correlation was calculated to examine the relationship between meteorological condition and child hospitalization for asthma and pneumonia. A human subject survey was conducted to examine the relationships between neighborhood environment and children asthma cases. The main finding was that children from families with health insurance, children from single father families and children from poor families were more likely to visit hospital for ACSCs and pneumonia care. "Hispanic families" and especially "Hispanic families with father but no mother" also contributed most to child hospitalization for ACSCs and pneumonia, suggesting that family preventative health care education is needed for Hispanic

    Purpose: To assess interobserver agreement (IOA) in the diagnosis of pulmonary infiltrates on chest X-rays for patients with community-acquired pneumonia (CAP). Materials and methods: From 7/2002 to 12/2005, 806 adults with CAP were included in the multicenter study 'CAPNETZ' (7 hospitals). Inclusion criteria were clinical signs of pneumonia and pulmonary opacification on chest X-rays. Each X-ray was reevaluated by two radiologists from the university hospital in consensus reading against the interpreter at the referring hospital in regard to: presence of infiltrate (yes/no/equivocal), transparency ({<=}/> 50%), localization, and pattern of infiltrates (alveolar/interstitial). The following parameters were documented: digital or film radiography, hospitalization, fever, findings of auscultation, microbiological findings. Results: The overall IOA concerning the detection of infiltrates was 77.7% (n = 626; Cl 0.75 - 0.81), the infiltrates were not verified in 16.4% (n = 132) by the referring radiologist with equivocal findings in 5.9% (n = 48). The IOA of the different clinical centers varied between 63.2% (n = 38, Cl 0.48 - 0.78) and 92.3% (n = 65, Cl 0.86 - 0.99). The IOA for the diagnosis of infiltrates was significantly higher for inpatients with 82.6% (n = 546; Cl 0.80-0.85) than for outpatients with 55.2% (n = 80; Cl 0.47 - 0.63), p < 0.0001. The IOA of infiltrates with a transparency > 50% was 95.1% (n = 215; Cl 0.92 - 0.98) versus 80.4% (n = 403; Cl 0.77 - 0.84) for infiltrates with a transparency > 50% (p < 0.0001). In patients with positive auscultation, the IOA was higher (p = 0,034). Chest X-rays of patients with antibiotic therapy or an alveolar infiltrate showed more equivocal findings compared to patients without these features. Conclusion: There is considerable interobserver variability in the diagnosis of pulmonary infiltrates on chest radiographs. The IOA is higher in more opaque infiltrates, positive auscultation and inpatients. (orig.)

    Positive blood cultures (BC) are considered a gold standard specific test for diagnosing and managing patients with community-acquired pneumonia (CAP). The aims of this study were to determine the positivity rate of BCs performed in patients with CAP, empirically started antibiotic regimens and conformity of the empirically started antibiotics with the results of BCs. Patients with the diagnosis of CAP with started empiric antibiotic treatment and performed BC test were included in the study. The BC set consisting of aerobic/anaerobic bottles was obtained from a single draw. Co-morbidities of patients, empirically started antibiotics and BC results were noted. Empiric antibiotics were checked as to whether they conform to BC results. The study included 262 patients with CAP. Majority of BC sets (195) revealed no bacterial growth. Of the total 262 sets of BCs, 67 (25.6%) sets displayed growth of organism and only 30 sets (11.5%) represented significant isolates. Commonly isolated microorganisms were Escherichia coli, Streptococcus species and Staphylococcus species. Ampicillin/Sulbactam and Fluoroquinolone combination was the leading antibiotic regimen chosen for the treatment (54.2%). The majority of patients had at least one co-morbidity. Ninety-six patients (37%) had a pulmonary disease, 74 (29%) had a malignancy, 74 (29%) had heart failure and 67 (26%) suffered from diabetes. Significantly positive results are rare (11.5%) and majority of blood cultures revealed negative results. BC tests may not be performed in all patients with CAP (Tab. 3, Ref. 11).

    We previously showed that 40 % of clinically stable patients hospitalised for community-acquired pneumonia (CAP) are not switched to oral therapy in a timely fashion because of physicians' barriers. We aimed to decrease this proportion by implementing a novel protocol. In a multi-centre controlled before-and-after study, we evaluated the effect of an implementation strategy tailored to previously identified barriers to an early switch. In three Dutch hospitals, a protocol dictating a timely switch strategy was implemented using educational sessions, pocket reminders and active involvement of nursing staff. Primary outcomes were the proportion of patients switched timely and the duration of intravenous antibiotic therapy. Length of hospital stay (LOS), patient outcome, education effects 6 months after implementation and implementation costs were secondary outcomes. Statistical analysis was performed using mixed-effects models. Prior to implementation, 146 patients were included and, after implementation, 213 patients were included. The case mix was comparable. The implementation did not change the proportion of patients switched on time (66 %). The median duration of intravenous antibiotic administration decreased from 4 days [interquartile range (IQR) 2-5] to 3 days (IQR 2-4), a decrease of 21 % [95 % confidence interval (CI) 11 %; 30 %) in the multi-variable analysis. LOS and patient outcome were comparable before and after implementation. Forty-three percent (56/129) of physicians attended the educational sessions. After 6 months, 24 % (10/42) of the interviewed attendees remembered the protocol's main message. Cumulative implementation costs were 5,798 (20/reduced intravenous treatment day). An implementation strategy tailored to previously identified barriers reduced the duration of intravenous antibiotic administration in hospitalised CAP patients by 1 day, at minimal cost.

    Full Text Available Lung ultrasonography (LUS is being increasingly utilized in emergency and critical settings. We performed a systematic review of the current literature to compare the accuracy of LUS and chest radiography (CR for the diagnosis of adult community-acquired pneumonia (CAP. We searched in Pub Med, EMBASE dealing with both LUS and CR for diagnosis of adult CAP, and conducted a meta-analysis to evaluate the diagnostic accuracy of LUS in comparison with CR. The diagnostic standard that the index test compared was the hospital discharge diagnosis or the result of chest computed tomography scan as a "gold standard". We calculated pooled sensitivity and specificity using the Mantel-Haenszel method and pooled diagnostic odds ratio using the DerSimonian-Laird method. Five articles met our inclusion criteria and were included in the final analysis. Using hospital discharge diagnosis as reference, LUS had a pooled sensitivity of 0.95 (0.93-0.97 and a specificity of 0.90 (0.86 to 0.94, CR had a pooled sensitivity of 0.77 (0.73 to 0.80 and a specificity of 0.91 (0.87 to 0.94. LUS and CR compared with computed tomography scan in 138 patients in total, the Z statistic of the two summary receiver operating characteristic was 3.093 (P = 0.002, the areas under the curve for LUS and CR were 0.901 and 0.590, respectively. Our study indicates that LUS can help to diagnosis adult CAP by clinicians and the accuracy was better compared with CR using chest computed tomography scan as the gold standard.

    Full Text Available OBJECTIVE: Evaluation of the clinical signs and symptoms predicting bacterial and viral pneumonia, in accordance with the Brazilian National Control Program for Acute Respiratory (ARI. METHODS: Observational prospective study. Seventy-six children from birth to six months of age who had pneumonia were studied in the emergency room. The patients were subdivided into two groups, based on radiological findings (gold-standard: 47 had bacterial pneumonia, and 29 had viral pneumonia. The frequencies, sensitivities, and specificities of the signs and symptoms were evaluated. RESULTS: The sensibilities and sensitivities of general findings in bacterial pneumonia were, respectively: fever 53.2%/40.0%; hypoactivity 68.4%/55.6% and prostration detected by the doctor 72.7%/55.0%. The same findings in viral pneumonias showed, respectively: 37.9%/40.0%, 66.7%/55.6% and 66.7%/55.6%. The sensibilities and sensitivities of respiratory findings in bacterial pneumonia were, respectively: coughing 66.0/38.1%, Respiratory rate = 50 ripm 76.6%/38.1%, altered respiratory auscultation 91.3%/10.5%, and chest indrawing 46.7%/80.0%. The same findings in viral pneumonias were, respectively: 69.0%/38.1%, 86.2%/38.1%, 85.7%/10.5% and 44.8%/80.0%. CONCLUSION: Analysis of signs and symptoms in each group did not distinguish bacterial from viral pneumonia. Our findings reinforce the adequacy of the ARI program in Brazil, which gives an early diagnosis of pneumonia, independent of its etiology.

    The Dutch Working Party on Antibiotic Policy (SWAB) and the Dutch Association of Chest Physicians (NVALT) convened a joint committee to develop evidence-based guidelines on the diagnosis and treatment of community acquired pneumonia (CAP). The guidelines are intended for adult patients with CAP who present at the hospital and are treated as outpatients as well as for hospitalised patients up to 72 hours after admission. Areas covered include current patterns of epidemiology and antibiotic resistance of causative agents of CAP in the Netherlands, the possibility to predict the causative agent of CAP on the basis of clinical data at first presentation, risk factors associated with specific pathogens, the importance of the severity of disease upon presentation for choice of initial treatment, the role of rapid diagnostic tests in treatment decisions, the optimal initial empiric treatment and treatment when a specific pathogen has been identified, the timeframe in which the first dose of antibiotics should be given, optimal duration of antibiotic treatment and antibiotic switch from the intravenous to the oral route. Additional recommendations are made on the role of radiological investigations in the diagnostic work-up of patients with a clinical suspicion of CAP, on the potential benefit of adjunctive immunotherapy, and on the policy for patients with parapneumonic effusions.

    Conclusion: LUS is a sensitive diagnostic tool with which to identify pneumonia in children. It is also useful in following up the progress of pneumonia. We suggest that LUS is a complementary tool to chest radiography in the diagnosis of pneumonia in children and that the follow up of pneumonia by LUS can reduce the exposure of children to ionizing radiation.

    Most clinical research investigated prognostic biomarkers for their ability to predict cardiovascular events or mortality. It is unknown whether biomarkers allow prediction of quality of life (QoL) after survival of the acute event. Herein, we investigated the prognostic potential of well-established inflammatory/cardiovascular blood biomarkers including white blood cells (WBC), C-reactive protein (CRP), procalcitonin (PCT), pro-adrenomedullin (proADM) and pro-atrial natriuretic peptide (proANP) in regard to a decline in QoL in a well-defined cohort of patients with community-acquired pneumonia (CAP). Within this secondary analysis including 753 patients with a final inpatient diagnosis of CAP from a multicenter trial, we investigated associations between admission biomarker levels and decline in QoL assessed by the EQ-5D health questionnaire from admission to day 30 and after 6 years. Admission proADM and proANP levels significantly predicted decline of the weighted EQ-5D index after 30 days (n=753) with adjusted odds ratios (ORs) of 2.0 ([95% CI 1.1-3.8]; p=0.027) and 3.7 ([95% CI 2.2-6.0]; pscale (VAS). Initial WBC, PCT and CRP values did not well predict QoL at any time point. ProADM and proANP accurately predict short- and long-term decline in QoL across most dimensions in CAP patients. It will be interesting to reveal underlying physiopathology in future studies.

    Available data on the etiology of community-acquired pneumonia (CAP) in Australia are very limited. Local treatment guidelines promote the use of combination therapy with agents such as penicillin or amoxycillin combined with either doxycycline or a macrolide. The Australian CAP Study (ACAPS) was a prospective, multicenter study of 885 episodes of CAP in which all patients underwent detailed assessment for bacterial and viral pathogens (cultures, urinary antigen testing, serological methods, and polymerase chain reaction). Antibiotic agents and relevant clinical outcomes were recorded. The etiology was identified in 404 (45.6%) of 885 episodes, with the most frequent causes being Streptococcus pneumoniae (14%), Mycoplasma pneumoniae (9%), and respiratory viruses (15%; influenza, picornavirus, respiratory syncytial virus, parainfluenza virus, and adenovirus). Antibiotic-resistant pathogens were rare: only 5.4% of patients had an infection for which therapy with penicillin plus doxycycline would potentially fail. Concordance with local antibiotic recommendations was high (82.4%), with the most commonly prescribed regimens being a penicillin plus either doxycycline or a macrolide (55.8%) or ceftriaxone plus either doxycycline or a macrolide (36.8%). The 30-day mortality rate was 5.6% (50 of 885 episodes), and mechanical ventilation or vasopressor support were required in 94 episodes (10.6%). Outcomes were not compromised by receipt of narrower-spectrum beta-lactams, and they did not differ on the basis of whether a pathogen was identified. The vast majority of patients with CAP can be treated successfully with narrow-spectrum beta-lactam treatment, such as penicillin combined with doxycycline or a macrolide. Greater use of such therapy could potentially reduce the emergence of antibiotic resistance among common bacterial pathogens.

    Full Text Available Nosocomial infection is an increasing problem. The global problem of antimicrobial resistance is particularly pressing in developing countries, where the infectious disease burden is high and cost constraints prevent the widespread application of newer, more expensive agents. In a prospective study, 203 consecutive cases with hospital-acquired infection in a university hospital in Bushehr port were evaluated. The most common hospital-acquired infection was urinary (76 cases, conjunctivitis (16 cases, bacteremia (8 cases, meningitis (5 cases, wound (3 cases, empyema (2 cases and peritonitis (1 case. The patients with hospital-acquired infection were from surgical and internal medicine I.C.Us (53.2% & 15.6%, respectively. The most frequent isolated organisms were Pseudomonas aeruginosa (25.6%, Acinetobacter baumannii (19.7%, E. coli (13.3%, Klebsiella pneumoniae (11.3%, Staphylococcus aureus (8.4%, Staphylococcus epidermidis (7.9%, Enterobacter species (7%, Streptococcus species (6.4%, and Proteus mirabilis (0.5%. The most resistant organisms to antimicrobial agents were Acinetobacter baumannii and Pseudomonas aeruginosa 97 & 93.3% of these bacteria were resistant to third generation cephalosporins. The isolated Staphylococcal species were resistant to amikacin (94%. In conclusion, gram negative bacteria were the most common etiologic agent of hospital-acquired infection and had a high level of resistance to amikacin and third generation cephalosporins. Therefore, new therapeutic strategies should be designed to combat these microorganisms.

    ABSTRACT OBJECTIVE: To verify the adequacy and factors associated with compliance with the immunization schedule (BCG, DTP-Hib, MMR, PCV-10) in children hospitalized with pneumonia at a pediatric referral hospital in Northeast Brazil. METHODS: This is a cross-sectional, descriptive study with an analytical component, with a sample of 452 children hospitalized with pneumonia at the Instituto de Medicina Integral Prof. Fernando Figueira, between 2010 and 2013. The inclusion criterion was children aged from one month to less than five years of age with proof in the immunization record. The exclusion criterion was the presence of hospital-acquired pneumonia or concomitant disease. We have evaluated the adequacy of the immunization schedule for the BCG, tetravalent, MMR, and 10-valent pneumococcal conjugate (PCV-10) vaccines. We used the chi-square test and Fisher's exact test followed by multivariate Poisson regression, estimating the crude and adjusted prevalence ratios and respective 95% confidence intervals. The variables with p < 0.20 in the univariate analysis were included in the multivariate analysis. RESULTS: There was good adequacy in the immunization schedule, except for PCV-10, which presented a percentage lower than 85%. We have observed an association between adequate compliance with the immunization schedule and education level of the mother (89.9% complete high school), sex of the child (87.2% female), age of the child (94.2% younger than six months), and breastfeeding (84.3% breastfed). CONCLUSIONS: Given the high rate of education level of the mother and the high percentage of breastfeeding, we can understand that there is a better understanding of the health of the child by the mothers studied in this study, showing the effectiveness of public policies for infant feeding. However, children did not have good adequacy of the immunization schedule of PCV-10, one of the main vaccines against pneumonia, which can be one of the main factors in the causes of

    Two nonsynchronous events have affected the management of community-acquired pneumonia (CAP): spiraling empiricism for CAP and the "golden era" of clinical microbiology. The development of broad-spectrum antibiotics has led to widespread empiric use without ascertaining the etiology of the infecting microbe. Unfortunately, this approach clashes with the second event, which is the advent of molecular-based microbiology that can identify the causative pathogen rapidly at the point of care. The urinary antigen is a most effective rapid test that has allowed targeted therapy for Legionnaire disease at the point of care. The high specificity (> 90%) allows the clinician to administer appropriate anti-Legionella therapy based on a single rapid test; however, its low sensitivity (76%) means that a notable number of cases of Legionnaire disease will go undiagnosed if other tests, especially culture, are not performed. Further, culture for Legionella is not readily available. If a culture is not performed, epidemiologic identification of the source of the bacterium cannot be ascertained by molecular fingerprinting of the patient and the putative source strain. We recommend resurrection of the basic principles of infectious disease, which are to identify the microbial etiology of the infection and to use narrow, targeted antimicrobial therapy. To reduce antimicrobial overuse with subsequent antimicrobial resistance, these basic principles must be applied in concert with traditional and newer tests in the clinical microbiology laboratory.

    Full Text Available Abstract Background Pneumococcal diseases remain a major cause of morbidity and mortality worldwide. Updated data on drug-resistance from different populations may be important to recognize changes in disease patterns. This study assessed current levels of penicilin resistance among Streptococcus Pneumoniae causing pneumonia in Spanish middle age and older adults. Methods Antimicrobial susceptibility was tested for 104 consecutive isolates of Streptococcus pneumoniae recovered from patients 50 years or older with radiographically confirmed pneumonia in the region of Tarragona (Spain between 2002 and 2007. According to the minimum inhibitory concentration of tested antimicrobials (penicillin, erythromycin, cefotaxime and levofloxacin strains were classified as susceptible or resistant. Antimicrobial resistance was determined for early cases (2002–2004 and contemporary cases (2005–2007. Results Twenty-seven (25.9% were penicillin-resistant strains (19 strains with intermediate resistance and 8 strains with high resistance. Penicillin-resistance was higher in 2002–2004 than in 2005–2007 (39.5% vs 18.2%, p = 0.017. Of 27 penicillin-resistant strains, 10 (37% were resistant to erythromycin, 8 (29.6% to cefotaxime, 2 (7.4% to levofloxacin, and 4 (14.8% were identified as multidrug resistant. Case-fatality rate was higher among those patients who had an infection caused by any penicillin susceptible strain (16.9% than in those with infections due to penicillin-resistant strains. Conclusion Resistance to penicillin among Streptococcus pneumoniae remains high, but such resistance does not result in increased mortality in patients with pneumococcal pneumonia.

    Full Text Available Safia Bader Uddin Shaikh, Zafar Ahmed, Syed Ali Arsalan, Sana Shafiq Department of Pulmonology, Liaquat National Hospital, Karachi, Pakistan Introduction: Moraxella catarrhalis previously considered as commensal of upper respiratory tract has gained importance as a pathogen responsible for respiratory tract infections. Its beta-lactamase-producing ability draws even more attention toward its varying patterns of resistance. Methods: This was an observational study conducted to evaluate the prevalence and resistance pattern of M. catarrhalis. Patients aged 20–80 years admitted in the Department of Chest Medicine of Liaquat National Hospital from March 2012 to December 2012 were included in the study. Respiratory samples of sputum, tracheal secretions, and bronchoalveolar lavage were included, and their cultures were followed. Results: Out of 110 respiratory samples, 22 showed positive cultures for M. catarrhalis in which 14 were males and eight were females. Ten samples out of 22 showed resistance to clarithromycin, and 13 samples out of 22 displayed resistance to erythromycin, whereas 13 showed resistance to levofloxacin. Hence, 45% of the cultures showed resistance to macrolides so far and 59% showed resistance to quinolones. Conclusion: Our study shows that in our environment, M. catarrhalis may be resistant to macrolides and quinolones; hence, these should not be recommended as an alternative treatment in community-acquired lower respiratory tract infections caused by M. catarrhalis. However, a study of larger sample size should be conducted to determine if the recommendations are required to be changed.

    Full Text Available Little is known about the epidemiology of nosocomial bloodstream infections in public hospitals in developing countries. We evaluated trends in incidence of hospital-acquired bacteremia (HAB and healthcare-associated bacteremia (HCAB and associated mortality in a developing country using routinely available databases.Information from the microbiology and hospital databases of 10 provincial hospitals in northeast Thailand was linked with the national death registry for 2004-2010. Bacteremia was considered hospital-acquired if detected after the first two days of hospital admission, and healthcare-associated if detected within two days of hospital admission with a prior inpatient episode in the preceding 30 days.A total of 3,424 patients out of 1,069,443 at risk developed HAB and 2,184 out of 119,286 at risk had HCAB. Of these 1,559 (45.5% and 913 (41.8% died within 30 days, respectively. Between 2004 and 2010, the incidence rate of HAB increased from 0.6 to 0.8 per 1,000 patient-days at risk (p<0.001, and the cumulative incidence of HCAB increased from 1.2 to 2.0 per 100 readmissions (p<0.001. The most common causes of HAB were Acinetobacter spp. (16.2%, Klebsiella pneumoniae (13.9%, and Staphylococcus aureus (13.9%, while those of HCAB were Escherichia coli (26.3%, S. aureus (14.0%, and K. pneumoniae (9.7%. There was an overall increase over time in the proportions of ESBL-producing E. coli causing HAB and HCAB.This study demonstrates a high and increasing incidence of HAB and HCAB in provincial hospitals in northeast Thailand, increasing proportions of ESBL-producing isolates, and very high associated mortality.

This study was done to investigate carbapenemase producing genomes among K. pneumoniae isolates in Isfahan, Central Iran. Materials and Methods: In a cross-sectional study from 2011 to 2012, 29 carbapenem resistant (according to disc diffusion method carbapenemase producing (according to modified Hodge test K. pneumoniae strains were collected from Intensive Care Unit (ICUs of Al-Zahra referral Hospital. In the strains with the lack of sensitivity to one or several carbapenems, beta-lactams, or beta-lactamases, there has been performed modified Hodge test to investigate carbapenmase and then only strains producing carbapenmases were selected for molecular methods. Results: In this study, there have been 29 cases of K. pneumoniae isolated from hospitalized patients in the (ICU. Three cases (10.3% contained blaVIM, 1 case (3.4% contained blaIMP, and 1 case (3.4% contained blaOXA. The genes blaNDM and blaKPC were not detected. Then, 16 cases (55.2% from positive cases of K. pneumoniae were related to the chip, 4 cases (13.8% to catheter, 6 cases (20.7% to urine, and 3 cases (10.3% to wound. Conclusion: It is necessary to monitor the epidemiologic changes of these carbapenemase genes in K. pneumoniae in our Hospital. More attention should be paid to nosocomial infection control measures. Other carbapenemase producing genes should be investigated.

    The Dutch Working Party on Antibiotic Policy in collaboration with the Dutch Association of Chest Physicians, the Dutch Society for Intensive Care and the Dutch College of General Practitioners have updated their evidence-based guidelines on the diagnosis and treatment of community-acquired pneumonia (CAP) in adults who present to the hospital. This 2016 update focuses on new data on the aetiological and radiological diagnosis of CAP, severity classification methods, initial antibiotic treatment in patients with severe CAP and the role of adjunctive corticosteroids. Other parts overlap with the 2011 guideline. Apart from the Q fever outbreak in the Netherlands (2007-2010) no other shifts in the most common causative agents of CAP or in their resistance patterns were observed in the last five years. Low-dose CT scanning may ultimately replace the conventional chest X-ray; however, at present, there is insufficient evidence to advocate the use of CT scanning as the new standard in patients evaluated for CAP. A pneumococcal urine antigen test is now recommended for all patients presenting with severe CAP; a positive test result can help streamline therapy once clinical stability has been reached and no other pathogens have been detected. Coverage for atypical microorganisms is no longer recommended in empirical treatment of severe CAP in the non-intensive care setting. For these patients (with CURB-65 score >2 or Pneumonia Severity Index score of 5) empirical therapy with a 2nd/3rd generation cephalosporin is recommended, because of the relatively high incidence of Gram-negative bacteria, and to a lesser extent S. aureus. Corticosteroids are not recommended as adjunctive therapy for CAP.

    Acute fibrinous and organising pneumonia (AFOP) is a rare histological pattern of interstitial lung disease. The authors describe a 60-year-old woman admitted to the hospital for sustained fever, presenting with an alveolar opacity on chest X-ray, with the presumed diagnosis of community-acquired pneumonia and the onset of antibiotics. Since serological results suggested that Legionella pneumophila was the infectious agent, she was discharged on levofloxacin. A week later, she was again admitted with fever. CT scan showed opacities with crescentic morphology and a central ground-glass area suggestive of cryptogenic organising pneumonia. Microbiological, serological and autoimmunity tests were negative. She underwent surgical lung biopsy that revealed inflammatory infiltrate, macrophage desquamation, fibroblasts proliferation and fibrin deposition in the alveolar spaces, consistent with AFOP. She started corticotherapy with good response. Disease relapsed after prednisolone discontinuation, 10 months later. Currently, the patient is on prednisolone 5 mg/day without clinical and radiological recurrence. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Community acquired-Clostridium difficile infection (CDI) has increased also in children in the last years. To determine the incidence of community-acquired CDI and to understand whether Clostridium difficile could be considered a symptom-triggering pathogen in infants. A five-year retrospective analysis (January 2007-December 2011) of faecal specimens from 124 children hospitalized in the Niguarda Ca' Granda Hospital for prolonged or muco-haemorrhagic diarrhoea was carried out. Stool samples were evaluated for common infective causes of diarrhoea and for Clostridium difficile toxins. Patients with and without CDI were compared for clinical characteristics and known risk factors for infection. Twenty-two children with CDI were identified in 5 years. An increased incidence of community-acquired CDI was observed, ranging from 0.75 per 1000 hospitalizations in 2007 to 9.8 per 1000 hospitalizations in 2011. Antimicrobial treatment was successful in all 19 children in whom it was administered; 8/22 CDI-positive children were younger than 2 years. No statistically significant differences in clinical presentation were observed between patients with and without CDI, nor in patients with and without risk factors for CDI. Our study shows that Clostridium difficile infection is increasing and suggests a possible pathogenic role in the first 2 years of life. Copyright © 2015 Editrice Gastroenterologica Italiana S.r.l.

    Existing severity assessment tools, such as the pneumonia severity index (PSI) and CURB-65 (tool based on confusion, urea level, respiratory rate, blood pressure, and age >or=65 years), predict 30-day mortality in community-acquired pneumonia (CAP) and have limited ability to predict which patients will require intensive respiratory or vasopressor support (IRVS). The Australian CAP Study (ACAPS) was a prospective study of 882 episodes in which each patient had a detailed assessment of severity features, etiology, and treatment outcomes. Multivariate logistic regression was performed to identify features at initial assessment that were associated with receipt of IRVS. These results were converted into a simple points-based severity tool that was validated in 5 external databases, totaling 7464 patients. In ACAPS, 10.3% of patients received IRVS, and the 30-day mortality rate was 5.7%. The features statistically significantly associated with receipt of IRVS were low systolic blood pressure (2 points), multilobar chest radiography involvement (1 point), low albumin level (1 point), high respiratory rate (1 point), tachycardia (1 point), confusion (1 point), poor oxygenation (2 points), and low arterial pH (2 points): SMART-COP. A SMART-COP score of >or=3 points identified 92% of patients who received IRVS, including 84% of patients who did not need immediate admission to the intensive care unit. Accuracy was also high in the 5 validation databases. Sensitivities of PSI and CURB-65 for identifying the need for IRVS were 74% and 39%, respectively. SMART-COP is a simple, practical clinical tool for accurately predicting the need for IRVS that is likely to assist clinicians in determining CAP severity.

  16. Emergency Department Management of a Myasthenia Gravis Patient with Community-Acquired Pneumonia: Does Initial Antibiotic Choice Lead to Cure or Crisis?

    2016-02-01

    Myasthenic crisis is a rare, yet serious condition that carries a 3%-8% mortality rate. Although infection is a common cause of decompensation in myasthenia gravis, several antibiotics classes have also been associated with an exacerbation. Selecting antibiotics can be a daunting clinical task and, if chosen inappropriately, can carry significant deleterious consequences. Not only do clinicians have to focus on treating the underlying infection appropriately, but avoiding antibiotics that may potentiate a myasthenic crisis is also vital. An 85-year-old female with a history of myasthenia gravis presented to the emergency department (ED) with increasing generalized weakness and shortness of breath. Clinical work-up was consistent with a community-acquired pneumonia (CAP) diagnosis. Her medical history included a myasthenia gravis exacerbation shortly after receiving moxifloxacin for CAP. After reviewing the patient's allergies, as well as potential antibiotic triggers, the decision was made to treat with tigecycline. The patient responded well to tigecycline therapy and was deemed stable for discharge on day 4 of hospitalization. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Evaluation of the myasthenia gravis patient frequently originates in the ED. It is important for clinicians to be able to distinguish between an underlying illness and a myasthenic crisis. In the event of an infectious process causing clinical deterioration in a myasthenia patient, optimal antibiotic selection becomes paramount. This patient case highlights the addition of tigecycline to the armamentarium of therapies available to treat myasthenia gravis patients presenting to the emergency department with CAP.

    Knowledge regarding whether benzodiazepines and similarly acting non-benzodiazepines (Z-drugs) are associated with an increased risk of pneumonia among older adults is lacking. We sought to investigate this association among community-dwelling adults with Alzheimer disease, a condition in which both sedative/hypnotic use and pneumonia are common. We obtained data on all community-dwelling adults with a recent diagnosis of Alzheimer disease in Finland (2005-2011) from the Medication use and Alzheimer disease (MEDALZ) cohort, which incorporates national registry data on prescriptions, reimbursement, hospital discharges and causes of death. Incident users of benzodiazepines and Z-drugs were identified using a 1-year washout period and matched with nonusers using propensity scores. The association with hospital admission or death due to pneumonia was analyzed with the Cox proportional hazards model and adjusted for use of other psychotropic drugs in a time-dependent manner. Among 49 484 eligible participants with Alzheimer disease, 5232 taking benzodiazepines and 3269 taking Z-drugs were matched 1:1 with those not taking these drugs. Collectively, use of benzodiazepines and Z-drugs was associated with an increased risk of pneumonia (adjusted hazard ratio [HR] 1.22, 95% confidence interval [CI] 1.05-1.42). When analyzed separately, benzodiazepine use was significantly associated with an increased risk of pneumonia (adjusted HR 1.28, 95% CI 1.07-1.54), whereas Z-drug use was not (adjusted HR 1.10, 95% CI 0.84-1.44). The risk of pneumonia was greatest within the first 30 days of benzodiazepine use (HR 2.09, 95% CI 1.26-3.48). Benzodiazepine use was associated with an increased risk of pneumonia among patients with Alzheimer disease. Risk of pneumonia should be considered when weighing the benefits and risks of benzodiazepines in this population. © 2017 Canadian Medical Association or its licensors.

    Full Text Available Background. Conjunctivitis is one of the most frequently occurring hospital-acquired infections among neonates, although it is less studied than potentially life-threatening infections, such as sepsis and pneumonia. Objectives. The aims of our work were to identify epidemiologic characteristics, pathogens, and susceptibility patterns of bacterial hospital-acquired conjunctivitis (HAC in a level III neonatal unit. Materials and Methods. Data were collected retrospectively from patient charts and laboratory databases. Hospital-acquired conjunctivitis was defined in accordance with the Centers for Disease Control/National Healthcare Safety Network (CDC/NHSN diagnostic criteria. Results. One or more episodes of HAC were diagnosed in 4,0% ( of 1492 neonates admitted during the study period. Most of the episodes involved premature (75,4% and low birth weight (75,4% neonates. Infection rates were higher among patients undergoing noninvasive mechanical ventilation (46,7%, parenteral nutrition (13,6%, and phototherapy (6,8%. Predominant pathogens included Serratia marcescens (27,9%, Escherichia coli (23%, and Pseudomonas aeruginosa (18%. Susceptibility patterns revealed bacterial resistances to several antibiotic classes. Gentamicin remains the adequate choice for empirical treatment of HAC in our NICU. Conclusion. It is important to know the local patterns of the disease in order to adjust prevention strategies. Our work contributes to the epidemiological characterization of a sometimes overlooked disease.

    The prognostic role of N-terminal pro-brain natriuretic peptide (NT-proBNP) in patients with community-acquired pneumonia (CAP) has not been evaluated. The aim of the present study was to investigate whether NT-proBNP level could predict mortality in hospitalised CAP patients. We performed a structured medical record review of all hospitalised CAP patients from May 2003 to October 2006, and classified patients into the 30-day survival and non-survival group. Data included demographic and clinical characteristics, and laboratory findings including NT-proBNP levels. The APACHE II scores, PSI (pneumonia severity index) and CURB65 (confusion, urea, respiratory rate, blood pressure and aged 65 or more) scores were calculated. Comparisons between survivors and non-survivors were made with χ(2), non-parametric tests and logistic regression and ROC analysis were used to compare the ability of NT-proBNP (adjusted for age, heart failure and creatinine), APACHE II, PSI and CURB65 to predict mortality. Of 502 patients, 61 (12.2%) died within 30 days. NT-proBNP levels were measured in 167 patients and were significantly higher in non-survivors compared to survivors (median 841.7 (IQR 267.1-3137.3) pg/ml vs 3658.0 (1863.0-7025.0) pg/ml, p=0.019). NT-proBNP was an independent predictor of mortality (adjusted OR 1.53; 95% CI 1.16 to 2.02, p=0.002). The AUC for NT-proBNP was 0.712 (95% CI, 0.613 to 0.812), which was comparable to those of PSI (0.749, p=0.531) and CURB65 (0.698, p=0.693), but inferior to that of APACHE II (0.831, p=0.037). Adding NT-proBNP to APACHE II, PSI and CURB65 did not significantly increase the AUCs, respectively. NT-proBNP level is an independent predictor of mortality in hospitalised CAP patients. The performance of NT-proBNP level is comparable to those of PSI and CURB65 in predicting mortality.

Totally, 492 patients with acute ischemic stroke and Glasgow Coma Scale ≤ 8 were enrolled in this study. Subjects were assigned to prior atorvastatin treatment group (n=268, PG and no prior treatment group (n=224, NG. All the patients were given 20 mg atorvastatin every night during their hospital stay. HAP frequency and 28-day mortality were measured. Levels of inflammatory biomarkers [white blood cell (WBC, procalcitonin (PCT, tumor necrosis factor-alpha (TNF-α, and interleukin-6 (IL-6] were tested. Results. There was no significant difference in the incidence of HAP between PG and NG (25.74% versus. 24.55%, p>0.05 and 28-day mortality (50.72% versus 58.18%, p>0.05. However, prior statin treatment did modify the mortality of ventilator associated pneumonia (VAP (36.54% versus 58.14%, p=0.041 and proved to be a protective factor (HR, 0.564; 95% CI, 0.310~0.825, p=0.038. Concentrations of TNF-α and IL-6 in PG VAP cases were lower than those in NG VAP cases (p<0.01. Conclusions. Prior atorvastatin treatment in patients with ischemic stroke was associated with a lower concentration of IL-6 and TNF-α and improved the outcome of VAP.

Survey respondents with unresolved symptoms or other CAP-related health problems completed a second survey 30 days later; a third survey was completed another 30 days later by respondents with unresolved symptoms or problems. Nationally representative results describing the average time to recovery of symptoms and other CAP-related problems were achieved using post-stratification weights.Results: Five hundred participants completed the initial survey. The time to resolution for the CAP symptoms of weakness, shortness of breath, and tiredness exceeded 3 weeks on average. There was an average of 13 days of absenteeism, and 3 weeks (mean =21 days before achieving full work/activity productivity after CAP. For participants with health conditions that worsened from pneumonia, chronic emphysema and chronic obstructive pulmonary disease took the longest to return to baseline (mean =60 and 52.4 days, respectively.Conclusion: The results from this study demonstrate that older adults surviving a CAP episode experience a significant multi-symptom illness with long recovery periods to achieve pre-CAP health and productivity.

    Rationale: Pneumonia is a frequent cause of hospitalization, yet drivers of post-pneumonia morbidity remain poorly characterized. Causes of hospital readmissions may elucidate important sources of morbidity and are of particular interest given the U.S. Hospital Readmission Reductions Program. Objectives: To review the primary diagnoses of early (≤30 d) and late (≥31 d) readmissions after pneumonia hospitalization. Methods: Systematic review of MEDLINE, Embase, and CINAHL databases. We identified original research studies of adults aged 18 years or older, hospitalized for pneumonia, and for whom cause-specific readmission rates were reported. Two authors abstracted study results and assessed study quality. Measurements and Main Results: Of the 1,243 citations identified, 12 met eligibility criteria. Included studies were conducted in the United States, Spain, Canada, Croatia, and Sweden. All-cause 30-day readmission rates ranged from 16.8 to 20.1% across administrative studies; the weighted average for the studies using chart review was 11.6% (15.6% in United States–based studies). Pneumonia, heart failure/cardiovascular causes, and chronic obstructive pulmonary disease/pulmonary causes are the most common reasons for early readmission after pneumonia hospitalization. Although it was the single most common cause for readmission, pneumonia accounted for only 17.9 to 29.4% of all 30-day readmissions in administrative studies and a weighted average of 23.0% in chart review studies. After accounting for study population, there was no clear difference in findings between claims-based versus chart-review studies. Few studies assessed readmissions beyond 30 days, although the limited available data suggest similar primary diagnoses for early and late readmissions. No studies assessed whether reasons for readmission were similar to patients’ reasons for healthcare use before hospitalization. Conclusions: Pneumonia, heart failure/cardiovascular disease, and chronic

    To assess incidence rate, risk factors and susceptibility patterns associated with extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli or Klebsiella pneumoniae in community-acquired urinary tract infections (CA-UTIs). A prospective, case-control study was conducted at a tertiary teaching hospital from Jan 2015 to Dec 2016. The results of microbiology cultures were initially screened to include only patients with positive E. coli or K. pneumoniae urine cultures. Afterwards, clinical symptoms were assessed to confirm the UTI. To investigate the risk factors, patients with a positive urine culture for ESBL-producing isolates were assigned as cases, while patients with non-ESBL were assigned as controls. Out of 591 patients included in this study, 57.5% (n = 340) were included in the control group and 42.5% (n = 251) were in the case group. The incidence rate of ESBL-producing isolates was 3.465 cases per 1000-patient hospital admissions. Male gender (OR = 1.856, 95% CI = 1.192-2.889, p = 0.006), pediatrics (OR = 1.676, 95% CI = 1.117-2.517, p = 0.013), patients with comorbidity (OR = 1.542, 95% CI = 1.029-2.312, p = 0.036) and UTI in the previous 12 months (OR = 1.705, 95% CI = 1.106-2.628, p = 0.016) were independently associated with a higher risk of infection. The resistance rate for most commonly prescribed antibiotics was high. Our results suggest that the incidence of ESBL producers among CA-UTIs is high. Male gender, pediatrics, comorbidity and UTI in the previous 12 months were associated with a higher risk for infection. Continuous surveillance and prudent antibiotic use by healthcare professionals are important factors for effective control of ESBL associated infections.

    Full Text Available Community-acquired pneumonia (CAP is a serious illness with a significant impact on individual patients and society as a whole. Over the past several years, there have been significant advances in the knowledge and understanding of the etiology of the disease, and an appreciation of problems such as mixed infections and increasing antimicrobial resistance. The development of additional fluoroquinolone agents with enhanced activity against Streptococcus pneumoniae has been important as well. It was decided that the time had come to update and modify the previous CAP guidelines, which were published in 1993. The current guidelines represent a joint effort by the Canadian Infectious Diseases Society and the Canadian Thoracic Society, and they address the etiology, diagnosis and initial management of CAP. The diagnostic section is based on the site of care, and the treatment section is organized according to whether one is dealing with outpatients, inpatients or nursing home patients.

    To develop an instrument for evaluating the quality of antibiotic management of patients with community-acquired pneumonia (CAP) applicable in a middle-income developing country. A previous study and Indonesian guidelines were reviewed to derive potential quality of care indicators (QIs). An expert panel performed a two-round Delphi consensus procedure on the QI's relevance to patient recovery, reduction of antimicrobial resistance and cost containment. Applicability in practice, including reliability, feasibility and opportunity for improvement, was determined in a data set of 128 patients hospitalised with CAP in Semarang, Indonesia. Fifteen QIs were selected by the consensus procedure. Five QIs did not pass feasibility criteria, because of inappropriate documentation, inefficient laboratory services or patient factors. Three QIs provided minor opportunity for improvement. Two QIs contradicted each other; one of these was considered not valid and excluded. A final set of six QIs was defined for use in the Indonesian setting. Using the Delphi method, we defined a list of QIs for assessing the quality of care, in particular antibiotic treatment, for CAP in Indonesia. For further improvement, a modified Delphi method that includes discussion, a sound medical documentation system, improvement of microbiology laboratory services, and multi-center applicability tests are needed to develop a valid and applicable QI list for the Indonesian setting. © 2014 John Wiley & Sons Ltd.

Methods: Hospital episodes including HAP treated by vancomycin or linezolid between 2008 and 2012 in a Chinese tertiary care hospital were retrospectively identified from hospital administrative databases. Propensity score methods created best-matched pairs for the antibiotics. The matched pairs were used for adjusted comparisons on clinical response and allocation of hospital costs. Multiple regression analyses adjusting residual imbalance after matching were performed to confirm adjusted comparisons. Results: Sixty matched pairs were created. Adjusted comparisons between vancomycin and linezolid showed similar clinical response rates (clinical cure: 30.0% versus 31.7%, respectively; P=0.847; treatment failure: 55.0% versus 45.0%, respectively; P=0.289 but a significantly lower in-hospital mortality rate for vancomycin (3.3% versus 18.3%, respectively; P=0.013. After further adjusting for the imbalanced variables between matched treatment groups, the risks of treatment failure associated with the two antibiotics were comparable (odds ratio: 1.139; P=0.308 and there was

    The epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) in hospitals has been changed in recent years due to the arrival of community-associated MRSA (CA-MRSA) strains into healthcare settings. The aim of this study is to investigate the distribution of staphylococcal cassette chromosome mec (SCCmec) type V as well as SCCmec IV subtypes, which have been associated with community-acquired infection among healthcare-associated MRSA (HA-MRSA) isolates. Antimicrobial susceptibility, SCCmec type, spa type and the presence of Panton-Valentine leukocidin (PVL) genes were determined for all HA-MRSA isolates in an Iranian referral hospital. In this study of 48 HA-MRSA isolates, 13 (27%), three (6.2%), five (10.4%) and one (2%) belonged to SCCmec subtypes IVa, IVb, IVc and IVd, respectively. Only two isolates (4.2%) belonged to SCCmec types V Notably, one isolate was found to harbour concurrent SCCmec subtypes IVb and IVd. MRSA containing SCCmec subtype IVb, IVc and IVd as well as type V isolates were all susceptible to chloramphenicol, clindamycin and rifampicin, while the sensitivity to these antibiotics was lower among MRSA containing SCCmec subtype IVa. The most frequently observed spa ttype was t037, accounting for 88% (22/25). Three other spa type was t002, t1816 and t4478. Large reservoirs of MRSA containing type IV subtypes and type V now exist in patients in this Iranian hospital. Therefore, effective infection control management in order to control the spread of CA-MRSA is highly recommended.

    To assess the impact of chronic liver disease (CLD) on ICU-acquired pneumonia. This was a prospective, observational study of the characteristics, microbiology, and outcomes of 343 consecutive patients with ICU-acquired pneumonia clustered according to the presence of CLD. Sixty-seven (20%) patients had CLD (67% had liver cirrhosis, LC), MELD score 26 ± 9, 20% Child-Pugh class C). They presented higher severity scores than patients without CLD both on admission to the ICU (APACHE II, LC 19 ± 6 vs. other CLD 18 ± 6 vs. no CLD 16 ± 6; p CLD patients. LC patients had higher 28- and 90-day mortality (63 vs. 28%, p CLD patients. Presence of LC was independently associated with decreased 28- and 90-day survival (95% confidence interval [CI], 1.982-17.250; p = 0.001; 95% confidence interval [CI], 2.915-20.699, p = 0.001, respectively). In critically ill patients with ICU-acquired pneumonia, CLD is associated with a more severe clinical presentation and poor clinical outcomes. Moreover, LC is independently associated with 28- and 90-day mortality. The results of this study are important for future trials focused on mortality.

    A short cut review was carried out to establish the prognostic value of B-type natriuretic peptides (BNP and NT-proBNP) in community acquired pneumonia (CAP). Three cohort studies were directly relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. The clinical bottom line was that B-type natriuretic peptides have prognostic value in CAP but further prospective studies were needed to assess their application in clinical practice.

    Fine resolution spatial variability in pneumonia hospitalization may identify correlates with socioeconomic, demographic and environmental factors. We performed a retrospective study within the Fairview Health System network of Minnesota. Patients 2 months of age and older hospitalized with pneumonia between 2011 and 2015 were geocoded to their census block group, and pneumonia hospitalization risk was analyzed in relation to socioeconomic, demographic and environmental factors. Spatial analyses were performed using Esri's ArcGIS software, and multivariate Poisson regression was used. Hospital encounters of 17 840 patients were included in the analysis. Multivariate Poisson regression identified several significant associations, including a 40% increased risk of pneumonia hospitalization among census block groups with large, compared with small, populations of ⩾65 years, a 56% increased risk among census block groups in the bottom (first) quartile of median household income compared to the top (fourth) quartile, a 44% higher risk in the fourth quartile of average nitrogen dioxide emissions compared with the first quartile, and a 47% higher risk in the fourth quartile of average annual solar insolation compared to the first quartile. After adjusting for income, moving from the first to the second quartile of the race/ethnic diversity index resulted in a 21% significantly increased risk of pneumonia hospitalization. In conclusion, the risk of pneumonia hospitalization at the census-block level is associated with age, income, race/ethnic diversity index, air quality, and solar insolation, and varies by region-specific factors. Identifying correlates using fine spatial analysis provides opportunities for targeted prevention and control.

    Cryptogenic Organising Pneumonia (COP) is a relatively rare condition and can be difficult to differentiate from Community acquired pneumonia (CAP). We report two cases which demonstrate the importance of considering this differential diagnosis in patients with spontaneous pneumothorax who have raised inflammatory markers or lung infiltrates. Our report highlights the value of serum procalcitonin as a biomarker in differentiating between community acquired pneumonia and cryptogenic organising pneumonia especially in the context of a high serum C-reactive protein. Furthermore, the cases show early diagnosis and prompt treatment with corticosteroids may impact the clinical outcome.

    The objective of root canal treatments (RCTs) is to control pulpal diseases and salvage infected teeth by eradicating microorganisms within the root canal system. However, an unfinished RCT can leave a space for bacterial accumulation, which can leak into the oral cavity and then aspirate into the lower respiratory tract and the lungs, causing infection. This study investigated the association of unfinished RCTs with the possible risk of pneumonia hospitalization using a nationwide population-based database. After a matching process, we recruited 116,490 subjects who received an initiated RCT and had no history of pneumonia before 2005 and observed until the end of 2011. An unfinished RCT was operationally defined as an endodontic session that was started on a tooth but had no subsequent completion records. Cox proportional hazards models and subgroup analyses were used to estimate the association of unfinished RCTs on the risk of pneumonia hospitalization. In total, 1285 subjects were hospitalized for pneumonia during 2005 to 2011 with an overall pneumonia hospitalization incidence rate of 0.22% per person year. After adjusting for confounding factors, the adjusted pneumonia hospitalization hazard ratio for subjects who had unfinished RCTs was 1.40 (95% confidence interval, 1.24-1.59) compared with subjects without unfinished RCTs (P endodontic treatments once started.

    The lung is one of the target organs of microangiopathy in diabetes mellitus (DM); patients with type 2 diabetes mellitus (T2DM) are vulnerable to pneumonia, and a variety of pathophysiological mechanisms has been described. This study aimed to determine the pathophysiological mechanism of community-acquired pneumonia (CAP) in T2DM patients. A total of 90 individuals was included in this study comprised of three groups (n = 30): healthy control, T2DM and T2DM+ CAP groups. Toll-like receptor (TLR)2 and 4 protein and messenger RNA expression in peripheral blood monocytes(PBMC) was assessed by western blot and reverse transcription-polymerase chain reaction, respectively, and surfactant protein A (SP-A) levels were examined in serum samples by enzyme-linked immunosorbent assay. In T2DM and T2DM+CAP groups, levels of both TLR2/4 protein and mRNA in PBMC were decreased compared with controls (P <0.05), with lower levels observed in the T2DM+CAP group in comparison with T2DM patients (P <0.05). The serum SP-A levels in T2DM+CAP individuals were significantly higher than the values obtained for T2DM patients (P <0.05). It also showed apparent increases when compared with that in controls although no statistical significance was detected. In T2DM patients with pneumonia, TLR2/4 levels in PBMC and serum SP-A were altered, maybe playing an important role in the susceptibility to pneumonia in T2DM patients. © 2016 Royal Australasian College of Physicians.

    The objective of the study was to estimate the length of stay of patients with hospital-acquired infections hospitalized in ICUs using a multistate model. Active prospective surveillance of hospital-acquired infection from January 1, 1995, to December 31, 2012. Twelve ICUs at the University of Lyon hospital (France). Adult patients age greater than or equal to 18 years old and hospitalized greater than or equal to 2 days were included in the surveillance. All hospital-acquired infections (pneumonia, bacteremia, and urinary tract infection) occurring during ICU stay were collected. None. The competitive risks of in-hospital death, transfer, or discharge were considered in estimating the change in length of stay due to infection(s), using a multistate model, time of infection onset. Thirty-three thousand four-hundred forty-nine patients were involved, with an overall hospital-acquired infection attack rate of 15.5% (n = 5,176). Mean length of stay was 27.4 (± 18.3) days in patients with hospital-acquired infection and 7.3 (± 7.6) days in patients without hospital-acquired infection. A multistate model-estimated mean found an increase in length of stay by 5.0 days (95% CI, 4.6-5.4 d). The extra length of stay increased with the number of infected site and was higher for patients discharged alive from ICU. No increased length of stay was found for patients presenting late-onset hospital-acquired infection, more than the 25th day after admission. An increase length of stay of 5 days attributable to hospital-acquired infection in the ICU was estimated using a multistate model in a prospective surveillance study in France. The dose-response relationship between the number of hospitalacquired infection and length of stay and the impact of early-stage hospital-acquired infection may strengthen attention for clinicians to focus interventions on early preventions of hospital-acquired infection in ICU.

At the same time specific features of pneumonia in patients with severe immune defects, against blood cancer including are studied insufficiently. By the result of microbiological examinations of 149 patients with pneumonia on the background of blood cancer, who have undergone treatment in hematological center of CE “Dnipropetrovsk local multi-field clinical hospital №4” in 2010-2012, bacterial causative agents were determined in 59,7% of accidents, among which gram-negative microorganisms made up 69,7%, gram-positive – 30,3%. In 63% of accidents the asso¬ciations of causative agents were determined: the combination of fungal flora made up 58, 4% bacterial associations – 25, 8%. Invasive methods of research have demonstrated a considerably bigger informativeness in determination of possible etiological diagnosis of pneumonia. In determination of causative agent in fluid of brochoalveolar lavage the part of positive results made up 77,4% against 30,3% in examination of sputum.

    To investigate the effectiveness of a quality improvement educational program in rural hospitals. Hospital-randomized controlled trial. A total of 47 rural and small community hospitals in Texas that had previously received a web-based benchmarking and case-review tool. The 47 hospitals were randomized either to receive formal quality improvement educational program or to a control group. The educational program consisted of two 2-day didactic sessions on continuous quality improvement techniques, followed by the design, implementation and reporting of a local quality improvement project, with monthly coaching conference calls and annual follow-up conclaves. Performance on core measures for community-acquired pneumonia and congestive heart failure were compared between study groups to evaluate the impact of the educational program. No significant differences were observed between the study groups on any measures. Of the 23 hospitals in the intervention group, only 16 completed the didactic program and 6 the full training program. Similar results were obtained when these groups were compared with the control group. While the observed results suggest no incremental benefit of the quality improvement educational program following implementation of a web-based benchmarking and case-review tool in rural hospitals, given the small number of hospitals that completed the program, it is not conclusive that such programs are ineffective. Further research incorporating supporting infrastructure, such as physician champions, financial incentives and greater involvement of senior leadership, is needed to assess the value of quality improvement educational programs in rural hospitals.

    Streptococcus pneumonia is the most common bacterial cause of community-acquired pneumonia in children. The reference standard for etiological diagnosis is isolation of S. pneumoniae from blood Since the advent of conjugate vaccines, disease caused by this organism can now be prevented. Many studies have been performed of the global incidence of invasive pneumococcal infections and of pneumococcal meningitis but few studies investigated bacteremic pneumococcal pneumonia and its complications in children. To determine the incidence, patient characteristics, clinical signs, laboratory data, percentage and days of hospitalization, response to antibiotic treatment, antibiotic resistance, complications and causal serogroups of bacteremic pneumococcal pneumonia in our environment in order to estimate requirements for systematic vaccination programs. From January 1990 to May 2001, data on all pediatric cases of invasive pneumococcal infections diagnosed in our hospital were collected. Several characteristics of patients with bacteremic pneumococcal pneumonia were analyzed. Bacteremic pneumococcal pneumonia was diagnosed in patients with positive blood or pleural fluid cultures for S. pneumoniae and radiographically evident pulmonary infiltrate. The incidence of both types of pneumonia were determined according to population census data. All S. pneumonia strains were sent to the Pneumococci Reference Laboratory of the Instituto Carlos III in Madrid for serotyping. We estimated the serotype coverage of the pneumococcal 7-valent conjugate vaccine according to the serotypes included in this vaccine and their distribution. Forty cases of bacteremic pneumococcal pneumonia were diagnosed, yielding an incidence of 17,10 and 5 cases per 10(5) children aged less than 2, 4 and 15 years old respectively. The mean age was 50 months and 43% were aged less than 4 years. Peaks occurred in January, March, April and May. A total of 77.5% of the patients were admitted to hospital and the

    Full Text Available It is not known whether rainfall increases the risk of sporadic cases of Legionella pneumonia. We sought to test this hypothesis in a prospective observational cohort study of non-immunosuppressed adults hospitalized for community-acquired pneumonia (1995-2011. Cases with Legionella pneumonia were compared with those with non-Legionella pneumonia. Using daily rainfall data obtained from the regional meteorological service we examined patterns of rainfall over the days prior to admission in each study group. Of 4168 patients, 231 (5.5% had Legionella pneumonia. The diagnosis was based on one or more of the following: sputum (41 cases, antigenuria (206 and serology (98. Daily rainfall average was 0.556 liters/m(2 in the Legionella pneumonia group vs. 0.328 liters/m(2 for non-Legionella pneumonia cases (p = 0.04. A ROC curve was plotted to compare the incidence of Legionella pneumonia and the weighted median rainfall. The cut-off point was 0.42 (AUC 0.54. Patients who were admitted to hospital with a prior weighted median rainfall higher than 0.42 were more likely to have Legionella pneumonia (OR 1.35; 95% CI 1.02-1.78; p = .03. Spearman Rho correlations revealed a relationship between Legionella pneumonia and rainfall average during each two-week reporting period (0.14; p = 0.003. No relationship was found between rainfall average and non-Legionella pneumonia cases (-0.06; p = 0.24. As a conclusion, rainfall is a significant risk factor for sporadic Legionella pneumonia. Physicians should carefully consider Legionella pneumonia when selecting diagnostic tests and antimicrobial therapy for patients presenting with CAP after periods of rainfall.

    Legionella pneumophila pneumonia (LPP) is of serious concern for chest physicians for its potential lethality and difficulty of diagnosis. In spite of widespread use of urine antigen detection method, it remains one of the most difficult-to-treat disease among community acquired pneumonia. We investigated CT images of 38 cases of LPP, comparing them with wide spread Streptococcus pneumoniae pneumonia (SPP). We find that sharply demarcated consolidation scattered in ground-glass opacity is the most striking and pathognomonic feature of LPP, which is rarely found in SPP. Bronchiolitis was not found in LPP, while it is a relatively common finding in SPP, which could be the second clue of differentiation of these two diseases. (author)

    Pneumonia is a common cause of hospitalization and can be complicated by the development of acute kidney injury. Acute kidney injury is associated with major adverse kidney events (death, dialysis, and durable loss of renal function [chronic kidney disease]). Because pneumonia and acute kidney injury are in part mediated by inflammation, we hypothesized that when acute kidney injury complicates pneumonia, major adverse kidney events outcomes would be exacerbated. We sought to assess the frequency of major adverse kidney events after a hospitalization for either pneumonia, acute kidney injury, or the combination of both. We conducted a retrospective database analysis of the national Veterans Affairs database for patients with a admission diagnosis of International Classification of Diseases-9 code 584.xx (acute kidney injury) or 486.xx (pneumonia) between October 1, 1999, and December 31, 2005. Three groups of patients were created, based on the diagnosis of the index admission and serum creatinine values: 1) acute kidney injury, 2) pneumonia, and 3) pneumonia with acute kidney injury. Patients with mean baseline estimated glomerular filtration rate less than 45 mL/min/1.73 m were excluded. The primary endpoint was major adverse kidney events defined as the composite of death, chronic dialysis, or a permanent loss of renal function after the primary discharge. The observations of 54,894 subjects were analyzed. Mean age was 68.7 ± 12.3 years. The percentage of female was 2.4, 73.3% were Caucasian, and 19.7% were African-American. Differences across the three diagnostic groups were significant for death, 25% decrease in estimated glomerular filtration rate from baseline, major adverse kidney events following admission, and major adverse kidney events during admission (all p pneumonia + acute kidney injury group (51% died and 62% reached major adverse kidney events). In both unadjusted and adjusted time to event analyses, patients with pneumonia + acute kidney injury

    To determine and compare hospitalization costs of bacterial community-acquired pneumonia cases via different costing methods under the Brazilian Public Unified Health System perspective. Cost-of-illness study based on primary data collected from a sample of 59 children aged between 28 days and 35 months and hospitalized due to bacterial pneumonia. Direct medical and non-medical costs were considered and three costing methods employed: micro-costing based on medical record review, micro-costing based on therapeutic guidelines and gross-costing based on the Brazilian Public Unified Health System reimbursement rates. Costs estimates obtained via different methods were compared using the Friedman test. Cost estimates of inpatient cases of severe pneumonia amounted to R$ 780,70/$Int. 858.7 (medical record review), R$ 641,90/$Int. 706.90 (therapeutic guidelines) and R$ 594,80/$Int. 654.28 (Brazilian Public Unified Health System reimbursement rates).

    Hospital admissions due to pneumonia range from 1.1 to 4 per 1,000 patients and this figure increases with age. Hospitalization causes a decline in functional status. Physical impairment impedes recovery and constitutes a higher risk of disability and mortality in elderly people. The objective of this study is to assess the impact of hospital stay in patients with pneumonia related with age. A total of 116 patients with pneumonia were included in this study, and divided into two age groups:psychological and emotional profile were evaluated. Pneumonia severity, nutritional status, independence and comorbidities were also assessed. Statistical analyses revealed significant differences between both age groups in pneumonia severity and comorbidities.

    Klebsiella pneumoniae ranks high as a cause of adult pneumonia requiring hospitalization in Malaysia. To study whether extended-spectrum b-lactamase (ESBL) producing K. pneumoniae was linked to hospital outcomes, we retrospectively studied 441 cases of adult respiratory tract infections with microbial proven K. pneumoniae from an urban-based university teaching hospital between 2003 and 2004. 47 (10.6%) cases had ESBL. Requirement for ventilation and median length of hospital stay, were great...

    Background: The role of Chlamydia pneumoniae (CP) and Mycoplasma pneumoniae (MP) in lower respiratory tract infections (LRTI) is still little known in community settings. Methods: In all, 3207 adult cases of LRTI (871 with pneumonia, and 2336 with acute bronchitis) were prospectively included in the ETIIC 1 ETIIC : ETude de l'Incidence des Infections respiratoires basses d'origine Communautaire dues a Chlamydia pneumoniae et Mycoplasma pneumoniae (Incidence of CP and MP in LRTI in community settings)program by 303 general practitioners and 24 hospital physicians in France between September 1997 and February 2000. The polymerase chain reaction and immunoassays were used to detect CP or MP in 3198 pharyngeal specimens obtained by gargling. Results: Of these 3198 patients, 232 (7.3%), were PCR-positive for CP and/or MP. Immunoassays were far less sensitive than PCRs (Se = 2 and 13% for MP and CP). Among the 2336 patients with acute bronchitis, PCR was positive for CP in 95 (4.1%), and for MP, in 54 (2.3%). Among the 671 patients with radiologically confirmed pneumonia, PCR was positive for CP in 23 (3.4%), and for MP in 49 (7.3%). CP and MP displayed significant geographic heterogeneity. Independent clinical determinants of positive PCR for CP and/or MP were age below 45 years, previous antimicrobial therapy (especially betalactams). Clinical signs were not of practical use in distinguishing accurately between etiologic diagnoses. Conclusions: CP or MP diagnosed by PCR were found in more than 7% of patients with LRTI in community settings with a significant geographical heterogeneity and significant temporal trends in the incidence

    Full Text Available Cryptogenic Organising Pneumonia (COP is a relatively rare condition and can be difficult to differentiate from Community acquired pneumonia (CAP. We report two cases which demonstrate the importance of considering this differential diagnosis in patients with spontaneous pneumothorax who have raised inflammatory markers or lung infiltrates. Our report highlights the value of serum procalcitonin as a biomarker in differentiating between community acquired pneumonia and cryptogenic organising pneumonia especially in the context of a high serum C-reactive protein. Furthermore, the cases show early diagnosis and prompt treatment with corticosteroids may impact the clinical outcome.

    Full Text Available The diffusion of multidrug-resistant (MDR bacteria has created the need to identify risk factors for acquiring resistant pathogens in patients living in the community.To analyze clinical features of patients with community-onset pneumonia due to MDR pathogens, to evaluate performance of existing scoring tools and to develop a bedside risk score for an early identification of these patients in the Emergency Department.This was an open, observational, prospective study of consecutive patients with pneumonia, coming from the community, from January 2011 to January 2013. The new score was validated on an external cohort of 929 patients with pneumonia admitted in internal medicine departments participating at a multicenter prospective study in Spain.A total of 900 patients were included in the study. The final logistic regression model consisted of four variables: 1 one risk factor for HCAP, 2 bilateral pulmonary infiltration, 3 the presence of pleural effusion, and 4 the severity of respiratory impairment calculated by use of PaO2/FiO2 ratio. A new risk score, the ARUC score, was developed; compared to Aliberti, Shorr, and Shindo scores, this point score system has a good discrimination performance (AUC 0.76, 95% CI 0.71-0.82 and calibration (Hosmer-Lemeshow, χ2 = 7.64; p = 0.469. The new score outperformed HCAP definition in predicting etiology due to MDR organism. The performance of this bedside score was confirmed in the validation cohort (AUC 0.68, 95% CI 0.60-0.77.Physicians working in ED should adopt simple risk scores, like ARUC score, to select the most appropriate antibiotic regimens. This individualized approach may help clinicians to identify those patients who need an empirical broad-spectrum antibiotic therapy.

Being married may decrease the risk of severe infections, due to better social support and healthier lifestyle. Patients and methods: In this population-based case-control study, we identified all adult patients with a first-time pneumonia-related hospitalization between 1994 and 2008 in Northern Denmark. For each case, ten sex- and age-matched population controls were selected from Denmark's Civil Registration System. We performed conditional logistic regression analysis to estimate the odds ratios (ORs for pneumonia hospitalization among persons who were divorced, widowed, or never married, as compared with married persons, adjusting for age, sex, 19 different comorbidities, alcoholism-related conditions, immunosuppressant use, urbanization, and living with small children. Results: The study included 67,162 patients with a pneumonia-related hospitalization and 671,620 matched population controls. Compared with controls, the pneumonia patients were more likely to be divorced (10% versus 7% or never married (13% versus 11%. Divorced and never-married patients were much more likely to have previous diagnoses of alcoholism-related conditions (18% and 11%, respectively compared with married (3% and widowed (6% patients. The adjusted OR for pneumonia-related hospitalization was increased, at 1.29 (95% confidence interval [CI]: 1.25-1.33 among divorced; 1.15 (95% CI: 1.12-1.17 among widowed; and 1.33 (95% CI: 1.29-1.37 among never-married individuals as compared with those who were married. Conclusion: Married individuals have a decreased risk of being hospitalized with pneumonia compared with never-married, divorced, and widowed patients

    Introduction. Community-acquired urinary tract infections (CAUTIs) are usually treated empirically. Geographical variations in etiologic agents and their antibiotic sensitivity patterns are common. Knowledge of antibiotic resistance trends is important for improving evidence-based recommendations for empirical treatment of UTIs. Our aim was to determine the major bacterial etiologies of CAUTIs and their antibiotic resistance patterns in a cosmopolitan area of Cameroon for comparison with prescription practices of local physicians. Methods. We performed a cross-sectional descriptive study at two main hospitals in Yaoundé, collecting a clean-catch mid-stream urine sample from 92 patients having a clinical diagnosis of UTI. The empirical antibiotherapy was noted, and identification of bacterial species was done on CLED agar; antibiotic susceptibility testing was performed using the Kirby-Bauer disc diffusion method. Results. A total of 55 patients had samples positive for a UTI. Ciprofloxacin and amoxicillin/clavulanic acid were the most empirically prescribed antibiotics (30.9% and 23.6%, resp.); bacterial isolates showed high prevalence of resistance to both compounds. Escherichia coli (50.9%) was the most common pathogen, followed by Klebsiella pneumoniae (16.4%). Prevalence of resistance for ciprofloxacin was higher compared to newer quinolones. Conclusions. E. coli and K. pneumoniae were the predominant bacterial etiologies; the prevalence of resistance to commonly prescribed antibiotics was high.

    Pneumonia and respiratory failure are common problems in the intensive care unit (ICU) setting, often occurring together. The relative prevalence of pneumonia types (community acquired, hospital acquired, ventilator associated) and causative pathogens is not well described in patients with respiratory failure. This was a prospective observational cohort study conducted in the medical ICU (34 beds) of Barnes-Jewish Hospital, an academic referral center of 1,300 beds from January 2016-December 2016. All patients who were prospectively adjudicated to have respiratory failure and pneumonia (RFP) regardless of pneumonia type were classified into one of four microbiologic categories: pathogen negative, antibiotic-susceptible pathogen (according to ceftriaxone susceptibility), antibiotic-resistant pathogen, and viruses. The primary outcomes assessed were the hospital mortality rate and inappropriate initial antibiotic therapy (IIAT) for non-viral pathogens. Among 364 consecutive patients with RFP, 63 (17.3%) had organisms that were antibiotic susceptible, 104 (28.6%) had antibiotic-resistant organisms, 118 (32.4%) were pathogen negative, and 79 (21.7%) had viral infections. For these categories, IIAT occurred in 3.2%, 21.2%, 0.8%, and 0, respectively (p < 0.001). Vasopressor-requiring shock was present in 61.9%, 72.1%, 68.6%, and 67.1%, respectively (p = 0.585), and the hospital mortality rates were 27.0%, 48.1%, 31.4%, and 36.7%, respectively (p = 0.020). Multivariable logistic regression analysis identified IIAT as an independent predictor of in-hospital death (adjusted odds ratio 5.28; 95% confidence interval 2.72-10.22; p = 0.012). Male gender, increasing Acute Physiology and Chronic Health Evaluation (APACHE) II scores, greater age, and the presence of shock also predicted death. Microbiologic categorization of patients with RFP suggests that antibiotic-resistant pathogens and viruses are associated with the highest mortality rates. Vasopressor

    Full Text Available Severe pneumonia remains an important cause of morbidity and mortality. Polymerase chain reaction (PCR has been shown to be more sensitive than current standard microbiological methods--particularly in patients with prior antibiotic treatment--and therefore, may improve the accuracy of microbiological diagnosis for hospitalized patients with pneumonia. Conventional detection techniques and multiplex PCR for 14 typical bacterial pneumonia-associated pathogens were performed on respiratory samples collected from adult hospitalized patients enrolled in a prospective multi-center study. Patients were enrolled from March until September 2012. A total of 739 fresh, native samples were eligible for analysis, of which 75 were sputa, 421 aspirates, and 234 bronchial lavages. 276 pathogens were detected by microbiology for which a valid PCR result was generated (positive or negative detection result by Curetis prototype system. Among these, 120 were identified by the prototype assay, 50 pathogens were not detected. Overall performance of the prototype for pathogen identification was 70.6% sensitivity (95% confidence interval (CI lower bound: 63.3%, upper bound: 76.9% and 95.2% specificity (95% CI lower bound: 94.6%, upper bound: 95.7%. Based on the study results, device cut-off settings were adjusted for future series production. The overall performance with the settings of the CE series production devices was 78.7% sensitivity (95% CI lower bound: 72.1% and 96.6% specificity (95% CI lower bound: 96.1%. Time to result was 5.2 hours (median for the prototype test and 43.5 h for standard-of-care.

    Full Text Available Abstract Background Most guidelines have been proposing, for more than 15 years, a β-lactam combined with either a quinolone or a macrolide as empirical, first-line therapy of severe community acquired pneumonia (CAP requiring ICU admission. Our goal was to evaluate the outcome of patients with severe CAP, focusing on the impact of new rather than old fluoroquinolones combined with β-lactam in the empirical antimicrobial treatments. Methods Retrospective study of consecutive patients admitted in a 16-bed general intensive care unit (ICU, between January 1996 and January 2009, for severe (Pneumonia Severity Index > or = 4 community-acquired pneumonia due to non penicillin-resistant Streptococcus pneumoniae and treated with a β-lactam combined with a fluoroquinolone. Results We included 70 patients of whom 38 received a β-lactam combined with ofloxacin or ciprofloxacin and 32 combined with levofloxacin. Twenty six patients (37.1% died in the ICU. Three independent factors associated with decreased survival in ICU were identified: septic shock on ICU admission (AOR = 10.6; 95% CI 2.87-39.3; p = 0.0004, age > 70 yrs. (AOR = 4.88; 95% CI 1.41-16.9; p = 0.01 and initial treatment with a β-lactam combined with ofloxacin or ciprofloxacin (AOR = 4.1; 95% CI 1.13-15.13; p = 0.03. Conclusion Our results suggest that, when combined to a β-lactam, levofloxacin is associated with lower mortality than ofloxacin or ciprofloxacin in severe pneumococcal community-acquired pneumonia.

    To test the hypothesis that compared with daily soap and water bathing, 2% chlorhexidine gluconate bathing every other day for up to 28 days decreases the risk of hospital-acquired catheter-associated urinary tract infection, ventilator-associated pneumonia, incisional surgical site infection, and primary bloodstream infection in surgical ICU patients. This was a single-center, pragmatic, randomized trial. Patients and clinicians were aware of treatment-group assignment; investigators who determined outcomes were blinded. Twenty-four-bed surgical ICU at a quaternary academic medical center. Adults admitted to the surgical ICU from July 2012 to May 2013 with an anticipated surgical ICU stay for 48 hours or more were included. Patients were randomized to bathing with 2% chlorhexidine every other day alternating with soap and water every other day (treatment arm) or to bathing with soap and water daily (control arm). The primary endpoint was a composite outcome of catheter-associated urinary tract infection, ventilator-associated pneumonia, incisional surgical site infection, and primary bloodstream infection. Of 350 patients randomized, 24 were excluded due to prior enrollment in this trial and one withdrew consent. Therefore, 325 were analyzed (164 soap and water versus 161 chlorhexidine). Patients acquired 53 infections. Compared with soap and water bathing, chlorhexidine bathing every other day decreased the risk of acquiring infections (hazard ratio = 0.555; 95% CI, 0.309-0.997; p = 0.049). For patients bathed with soap and water versus chlorhexidine, counts of incident hospital-acquired infections were 14 versus 7 for catheter-associated urinary tract infection, 13 versus 8 for ventilator-associated pneumonia, 6 versus 3 for incisional surgical site infections, and 2 versus 0 for primary bloodstream infection; the effect was consistent across all infections. The absolute risk reduction for acquiring a hospital-acquired infection was 9.0% (95% CI, 1.5-16.4%; p

    Full Text Available Streptococcus agalactiae, a colonizing agent in pregnant women and the main cause of neonatal sepsis and meningitis, has been increasingly associated with invasive disease in nonpregnant adults. We collected a total of 87 non-repetitive S. agalactiae isolates causing community-acquired (CA and hospital-acquired (HA infections in nonpregnant adults from a teaching hospital in Shanghai between 2009 and 2013. We identified and characterized their antibiotic resistance, sequence type (ST, serotype, virulence, and biofilm formation. The most frequent STs were ST19 (29.9%, ST23 (16.1%, ST12 (13.8%, and ST1 (12.6%. ST19 had significantly different distributions between CA- and HA-group B Streptococci (GBS isolates. The most frequent serotypes were III (32.2%, Ia (26.4%, V (14.9%, Ib (13.8%, and II (5.7%. Serotype III/ST19 was significantly associated with levofloxacin resistance in all isoates. The HA-GBS multidrug resistant rate was much higher than that of CA-GBS. Virulence genes pavA, cfb were found in all isolates. Strong correlations exist between serotype Ib (CA and HA and surface protein genes spb1 and bac, serotype III (HA and surface protein gene cps and GBS pilus cluster. The serotype, epidemic clone, PFGE-based genotype, and virulence gene are closely related between CA-GBS and HA-GBS, and certain serotypes and clone types were significantly associated with antibiotic resistance. However, CA-GBS and HA-GBS still had significant differences in their distribution of clone types, antibiotic resistance, and specific virulence genes, which may provide a basis for infection control.

    Because the few previous studies on underlying causes of recurrent pneumonia in children have come from tertiary care referral centres where selection bias may be important, the aim of this study was to examine underlying causes of recurrent pneumonia in children in a general hospital. We performed a retrospective chart review in a general hospital of 62 children with recurrent pneumonia over a 7.5 years period. In 19 patients (30.6%), no cause was identified, commonly because favourable natural history obviated the need for a full and invasive diagnostic work-up. Other underlying causes included recurrent aspiration in 16 patients (25.7%), lung disease (airway stenosis, bronchiectasis, middle lobe syndrome or tracheooesophageal fistula) in 10 patients (16.1%) and immune deficiency in 10 patients (16.1%). In contrast to previous studies, asthma was never diagnosed as an underlying cause, but diagnostic confusion between asthma (or recurrent upper respiratory tract infections) and recurrent pneumonia was common. The cause of recurrent pneumonia in children remains elusive in almost a third of patients, partly because the favourable natural history consistent with immune system maturation eliminates the need for further diagnostic procedures. Asthma is more likely a differential diagnostic consideration than an underlying cause of recurrent pneumonia in children. A standardised diagnostic guideline is needed to improve knowledge on causes of recurrent pneumonia in children. © 2013 The Authors.

    The emergence of colistin resistance may further contribute to treatment failure of infection caused by multidrug-resistant (MDR) Klebsiella pneumoniae. The colistin resistance rates were determined and colistin-resistant carbapenemase-producing K. pneumoniae (COL-R CP-Kp) were characterized over an 18-month period in a Greek hospital. Out of 135 carbapenemase producers, 19 isolates (14%) were categorized as resistant to colistin. Phenotypic and molecular characterization of the COL-R CP-Kp isolates revealed that all were MDR blaKPC producers and, excluding one isolate of MLST ST383, belonged to the international clonal lineage ST258. Furthermore, PCR amplification and sequencing of the mgrB locus revealed nucleotide sequences of different sizes and insertions of IS1- and IS5-like mobile elements. The majority (63%) of the COL-R blaKPC producers was recovered from patients in the intensive care unit (ICU) and clinical data indicated that all patients should have acquired these isolates in the ICU. The findings of the present study underscore a concerning evolution of colistin resistance in a setting of high K. pneumoniae carbapenemase (KPC)-Kp endemicity, such as Greece. Thus, continuous surveillance, molecular characterization, prudent use of antibiotics, and implementation of infection control measures for K. pneumoniae are urgent.

    Klebsiella pneumoniae ( K. pneumoniae ) is an important opportunistic pathogen causes serious community and hospital-acquired infections, which is highly resistant to antibiotics. We aimed to determine the frequency of multidrug resistant (MDR) and molecular typing of clinical isolates of K. pneumoniae . One hundred isolates of K. pneumoniae were collected from clinical samples in three general hospitals in Kermanshah. The antimicrobial susceptibility and extended-spectrum beta-lactamases (ESBL) production of isolates were determined using disk diffusion and combined disk methods, respectively. The bla CTX-M gene, class I and II integrons were detected using polymerase chain reaction. The bla CTX-M positive isolates were selected for genotyping using pulsed-field gel electrophoresis (PFGE). MDR phenotype was observed in 56% of isolates. The 40% of isolates were ESBL positive and 35 isolates contained bla CTX-M . Class I and II of integrons were detected in 50 (89.2%) and 39 (69.6%) of MDR isolates, respectively. PFGE patterns of K. pneumoniae bla CTX-M positive isolates indicated 19 clusters (X 1-19 ) with different genotype patterns. The study findings highlight the concern of circulating MDR strains of K. pneumoniae with bla CTX-M and class I and II integrons in Kermanshah hospitals. The presence of integrons among isolates may facilitate the spread of new resistance genes in this bacterium. Therefore, surveillance for the spread of MDR strains of this bacterium is recommended in hospitals.

    Full Text Available Infections associated with medical procedures, or hospital-acquired infections (HAIs, occur in all hospitals worldwide. An integrated infection-control program with HAI surveillance as its cornerstone can reduce the incidence of HAIs and contribute to economic benefits. The aim of this paper was to report the prevalence and epidemiological features of HAI in hospitals in Vojvodina, Serbia. The study population examined herein was compromised of all of the patients present in the ward at least 48 hours before the day of surveillance. It also included patients that were scheduled for discharge or transfer, and those temporarily absent from the ward for examinations or diagnostic procedures. Data were collected using uniform questionnaires, created by the scientific board of the study. Data from paper questionnaires were entered into a specially created electronic database and analyzed using standard statistical methods. A total of 2 435 patients were included in the study. The frequency of patients with HAI was 6.6% (95% CI: 5.6%-7.6%, and the prevalence of infection was 7.1% (95% CI: 6.1%-8.1%. HAI prevalence was significantly different depending on the ward, ranging from 1.7% in the gynecology department to 18.1% in intensive care departments. The most common type of HAI was pneumonia, representing 20.9% of all reported HAIs. The second most frequently reported type of HAI was surgical site infection (19.8%, followed by urinary tract infection (17.4%, gastro-intestinal infection (14.5% and bloodstream infection (11.0%. The most commonly found microorganisms were Enterococcus spp. (14.5%, Klebsiella pneumoniae (14.5%, Acinetobacter spp. (13.7%, coagulase-negative Staphylococcus spp. (12.1%, Pseudomonas aeruginosa (10.5% and Clostridium difficile (7.3%. The most frequently used antibiotics in therapy were third generation cephalosporins to which most of the isolates showed resistance. Although the consumption of carbapenems in this sample was only

    Full Text Available We report a case of Legionella pneumonia in a 78-year-old patient affected by cerebellar haemangioblastoma continuously hospitalised for 24 days prior to the onset of overt symptoms. According to the established case definition, this woman should have been definitely classified as a nosocomial case (patient spending all of the ten days in hospital before onset of symptoms. Water samples from the oncology ward were negative, notably the patient’s room and the oxygen bubbler, and the revision of the case history induced us to verify possible contamination in water samples collected at home. We found that the clinical strain had identical rep-PCR fingerprint of L. pneumophila serogroup 1 isolated at home. The description of this culture-proven case of Legionnaires’ disease has major clinical, legal, and public health consequences as the complexity of hospitalised patients poses limitations to the rule-of-thumb surveillance definition of nosocomial pneumonia based on 2–10-day incubation period.

    Full Text Available Background: Although prevalence of MRSA strains is reported to be increasing, there are no studies of their prevalence in community-acquired primary pyodermas in western India. Aims: This study aimed at determining the prevalence of MRSA infection in community-acquired primary pyodermas. Methods: Open, prospective survey carried out in a tertiary care hospital in Mumbai. Materials and Methods: Eighty-six patients with primary pyoderma, visiting the dermatology outpatient, were studied clinically and microbiologically. Sensitivity testing was done for vancomycin, sisomycin, gentamicin, framycetin, erythromycin, methicillin, cefazolin, cefuroxime, penicillin G and ciprofloxacin. Phage typing was done for MRSA positive strains. Results : The culture positivity rate was 83.7%. Staphylococcus aureus was isolated in all cases except two. Barring one, all strains of Staphylococcus were sensitive to methicillin. Conclusions: Methicillin resistance is uncommon in community-acquired primary pyodermas in Mumbai. Treatment with antibacterials active against MRSA is probably unwarranted for community-acquired primary pyodermas.

    It has been suggested that placing critically ill ventilated patients in a semirecumbent position minimizes the likelihood of nosocomial pneumonia. This pilot study explores whether the incidence of ventilator-acquired pneumonia (VAP) can be reduced by elevating the head of the bed to 45 degrees. The design is quantitative in nature, using a randomized controlled trial. The method involves adult ventilated patients being randomly assigned to one of two positions, i.e. 45 degrees raised head of bed (treatment group) or 25 degrees raised head of bed (control group). Data collection relied upon the diagnosis of clinically suspected and microbiologically confirmed pneumonia defined by the Consensus Conference on VAP. Thirty patients were included in the study--17 in the treatment group and 13 in the control group. Results showed that 29% (five) in the treatment group and 54% (seven) in the control group contracted VAP (P VAP in the patients nursed at 45 degrees. However, because of the sample size this difference did not reach statistical significance.

    Pneumonia is complicated by high rate of mortality and cardiovascular events (CVEs). The potential benefit of aspirin, which lowers platelet aggregation by inhibition of thromboxane A2 production, is still unclear. The aim of the study was to assess the impact of aspirin on mortality in patients with pneumonia. Consecutive patients admitted to the University-Hospital Policlinico Umberto I (Rome, Italy) with community-onset pneumonia were recruited and prospectively followed up until discharge or death. The primary end point was the occurrence of death up to 30 days after admission; the secondary end point was the intrahospital incidence of nonfatal myocardial infarction and ischemic stroke. One thousand and five patients (age, 74.7±15.1 years) were included in the study: 390 were receiving aspirin (100 mg/day) at the time of hospitalization, whereas 615 patients were aspirin free. During the follow-up, 16.2% of patients died; among these, 19 (4.9%) were aspirin users and 144 (23.4%; PFiO(2) ratio <300 negatively influenced survival, whereas aspirin therapy was associated with improved survival. Compared to patients receiving aspirin, the propensity score adjusted analysis confirmed that patients not taking aspirin had a hazard ratio of 2.07 (1.08 to 3.98; P=0.029) for total mortality. This study shows that chronic aspirin use is associated with lower mortality rate within 30 days after hospital admission in a large cohort of patients with pneumonia. © 2015 The Authors.

    Nosocomial pneumonia poses great challenge to an intensivist. Detailed information about hospital-acquired pneumonia (HAP) and ventilator-acquired pneumonia (VAP) is crucial for prevention and optimal management, thus improving quality Intensive Care Unit (ICU) care. Hence, we aimed to study the current trend of nosocomial pneumonia in ICU. It was a prospective observational cohort study, conducted in the ICU of a tertiary care teaching public hospital over a period of 18 months. We studied clinical profile and outcome of 120 adult patients who developed VAP/HAP during the study period. We also analyzed the causative organisms, antibiotic sensitivity, and resistance pattern in these patients. Out of 120 patients, 29 patients were HAP and 91 patients were VAP. Mortality was 60% (72), and development of VAP and requirement of mechanical ventilation showed significant association with mortality (P antibiotiques et le modèle de résistance chez ces patients. Résultats: Sur 120 patients, 29 patients étaient HAP et 91 patients étaient VAP. La mortalité était de 60% (72), et le développement du VAP et l'exigence de ventilation mécanique ont montré une association significative avec la mortalité (P antibiotique maximale a été observée chez la pipéracilline + tazobactam (58,8%), suivie de l'imipénème (49,5%) et du méropénem (41,8%), alors que la résistance antibiotique maximale a été observée à cefépime (95,1%), suivie de ceftazidime et de l'amoxicilline (91,2%) . la pneumonie nosocomiale a montré une incidence élevée (17,44%) et la mortalité (60%). Les organismes communs identifiés étaient S. aureus et K. pneumoniae. La résistance était élevée pour les antibiotiques couramment utilisés et une forte sensibilité aux antibiotiques pour la pipéracilline + le tazobactam et le carbapénème.

    Klebsiella pneumoniae ranks high as a cause of adult pneumonia requiring hospitalization in Malaysia. To study whether extended-spectrum b-lactamase (ESBL) producing K. pneumoniae was linked to hospital outcomes, we retrospectively studied 441 cases of adult respiratory tract infections with microbial proven K. pneumoniae from an urban-based university teaching hospital between 2003 and 2004. 47 (10.6%) cases had ESBL. Requirement for ventilation and median length of hospital stay, were greater in ‘ESBL’ than in ‘non-ESBL’ group [34% vs. 7.4%, p<0.001; 14 days vs. 5 days, p<0.001 respectively] but not crude hospital mortality rate [21.3% vs. 12.4%, p=0.092]. There was a four-fold increased risk of requiring ventilation [4.61 (2.72–7.85)] when ESBL was present. Our findings support the association of ESBL producing K. pneumoniae with adversed hospital outcomes and reiterate the need for vigilance on the part of treating clinicians. PMID:22993489

    Epidemiological analyses demonstrate that pneumonia survivors have a higher risk of myocardial infarction than people with similar load of risk factors for atherosclerotic cardiovascular disease (ASCVD) but without pneumonia. This may be due to a higher baseline burden of ASCVD in patients with pneumonia that is not captured by the accounting of known ASCVD risk factors in epidemiological analyses or to unfavorable accelerating effects of pneumonia on atherosclerosis. We analyzed data from the Multi-Ethnic Study of Atherosclerosis. We identified 54 participants that were hospitalized for pneumonia during study follow-up and that also had assessment of coronary artery calcium (CAC, an objective marker of coronary atherosclerotic burden) before and after this hospitalization. We matched them to 54 participants who were not hospitalized for pneumonia but that had CAC assessments at the same study visits as the pneumonia cases. We compared baseline CAC scores and their progression between groups. Baseline CAC scores were similar in both groups (median [IQR]; 6.3 [0-356.8] in pneumonia participants vs. 10.8 [0-178.3] in controls; p = 0.25). After a median of 4.8 years, the direction and magnitude of CAC score change, and the slope of CAC score progression between groups was also similar (median change [IQR], 21.8 [0 to 287.29] in participants with pneumonia versus 15.8 [0 to 140.94] in controls, p = 0.28; difference in slope, 7.7, 95% CI -9.0 to 24.6, p = 0.18). However, among participants with high baseline ASCVD risk (i.e. ACC/AHA 10-year risk estimate ≥7.5%), participants with pneumonia showed a larger increase in CAC scores (median change [IQR]; 159.10 [38.55-407.34] versus 48.72 [0.97-246.99] in controls; p = 0.02) and a trend towards a steeper slope of CAC score progression (difference in slope, 19.7, 95% CI -6.6 to 45.6, p = 0.07). Pneumonia may accelerate the progression of atherosclerosis in people with high baseline ASCVD risk.

The purpose of this study is to assess how these changes could affect the initial efficacy of ertapenem and ceftriaxone in the treatment of community-acquired pneumonia (CAP in elderly patients and the potential consequences this may have in health care costs. Methods: Initial efficacy in elderly was obtained from a combined analysis of two multicenter, randomized studies. An alternative scenario was carried out using initial efficacy data according to the pneumonia severity index (PSI. Country-specific pathogens distribution was obtained from a national epidemiological study, and microbiological susceptibilities to first- and second-line therapies were obtained from Spanish or European surveillance studies. A decision analytic model was used to compare ertapenem versus ceftriaxone for CAP inpatient treatment. Inputs of the model were the expected effectiveness previously estimated and resource use considering a Spanish national health system perspective. Outcomes include difference in proportion of successfully treated patients and difference in total costs between ertapenem and ceftriaxone. The model performed one-way and probabilistic sensitivity analyses. Results: First-line treatment of CAP with ertapenem led to a higher proportion of successfully treated patients compared with ceftriaxone in Spain. One-way sensitivity analysis showed that length of stay was the key parameter of the model. Probabilistic

    Community-acquired pneumonia (CAP) causes a major burden to the health care system among children under-5 years worldwide. Information on respiratory viruses in non-severe CAP cases is scarce. To estimate the frequency of respiratory viruses among non-severe CAP cases. Prospective study conducted in Salvador, Brazil. Out of 820 children aged 2-59 months with non-severe CAP diagnosed by pediatricians (respiratory complaints and radiographic pulmonary infiltrate/consolidation), recruited in a clinical trial (ClinicalTrials.gov Identifier NCT01200706), nasopharyngeal aspirate samples were obtained from 774 (94.4%) patients and tested for 16 respiratory viruses by PCRs. Viruses were detected in 708 (91.5%; 95%CI: 89.3-93.3) cases, out of which 491 (69.4%; 95%CI: 65.9-72.7) harbored multiple viruses. Rhinovirus (46.1%; 95%CI: 42.6-49.6), adenovirus (38.4%; 95%CI: 35.0-41.8), and enterovirus (26.5%; 95%CI: 23.5-29.7) were the most commonly found viruses. The most frequent combination comprised rhinovirus plus adenovirus. No difference was found in the frequency of RSVA (16.1% vs. 14.6%; P = 0.6), RSVB (10.9% vs. 13.2%; P = 0.4) influenza (Flu) A (6.3% vs. 5.1%; P = 0.5), FluB (4.5% vs. 1.8%; P = 0.09), parainfluenza virus (PIV) 1 (5.1% vs. 2.8%; P = 0.2), or PIV4 (7.7% vs. 4.1%; P = 0.08), when children with multiple or sole virus detection were compared. Conversely, rhinovirus, adenovirus, enterovirus, bocavirus, PIV2, PIV3, metapneumovirus, coronavirus OC43, NL63, 229E were significantly more frequent among cases with multiple virus detection. Respiratory viruses were detected in over 90% of the cases, out of which 70% had multiple viruses. Several viruses are more commonly found in multiple virus detection whereas other viruses are similarly found in sole and in multiple virus detection. Copyright © 2018 Elsevier B.V.

    The objective is to describe the process of care and prescription practices for CAP patients in four university hospitals in Colombia. Patients older than 15 years with a diagnosis of CAP during the two years study period. Collection of demographic and clinical status data and management during the first day of consult, classification in severity groups according to fine's prediction rule. Evaluation of the frequency of use of ancillary diagnostic tests antimicrobials prescription and agreement with ATS guidelines according to severity group and hospital. 734 patients were included, mean age 56 years old, 50.5% males, mean length of stay 8.6 days, 39% fine's classes IV to V. Frequency of sputum sampling (overall cohort between hospitals rank) was 46% (10 - 67%), chest x-ray 95% (57-100%), blood cultures 34% (0 -63%) and arterial blood gas analysis 71% (10-88%). the use of ancillary diagnostic test had wide variation between hospitals and severity classes, specially for sputum and blood gases. At least 45 different antimicrobial protocols were used in the cohort. Overall agreement between actual prescription and guidelines recommendations was variable (mean 44%, range 22 to 72%) between groups and hospitals, but without significant impact on mortality. There are many differences between actual clinical practice and guidelines for the management of CAP and wide variations between hospitals, but the precise effect of the lack of guideline-adherence on mortality is unclear

    Anaerobes used to be the most common cause of community-acquired lung abscess, and Streptococcus species used to be the second most common cause. In recent years, this has been changing. Klebsiella pneumoniae is now an increasing cause of community- acquired lung abscess, but Streptococcus species continue to be major pathogens. Necrotizing pneumonia has generally been regarded as a rare complication of pneumococcal infection in adults. Type 3 Streptococcus pneumoniae was the single most common type implicated in necrosis; however, many other serotypes were implicated. This entity predominately infects children, but is present also in adults. Lung abscess in adults due to Streptococcus pneumoniae is not common. In this regard we present a case series of pulmonary cavitation due to Streptococcus pneumoniae and discuss the possible pathogenic mechanism of the disease.

    Full Text Available Introduction. Community-acquired urinary tract infections (CAUTIs are usually treated empirically. Geographical variations in etiologic agents and their antibiotic sensitivity patterns are common. Knowledge of antibiotic resistance trends is important for improving evidence-based recommendations for empirical treatment of UTIs. Our aim was to determine the major bacterial etiologies of CAUTIs and their antibiotic resistance patterns in a cosmopolitan area of Cameroon for comparison with prescription practices of local physicians. Methods. We performed a cross-sectional descriptive study at two main hospitals in Yaoundé, collecting a clean-catch mid-stream urine sample from 92 patients having a clinical diagnosis of UTI. The empirical antibiotherapy was noted, and identification of bacterial species was done on CLED agar; antibiotic susceptibility testing was performed using the Kirby-Bauer disc diffusion method. Results. A total of 55 patients had samples positive for a UTI. Ciprofloxacin and amoxicillin/clavulanic acid were the most empirically prescribed antibiotics (30.9% and 23.6%, resp.; bacterial isolates showed high prevalence of resistance to both compounds. Escherichia coli (50.9% was the most common pathogen, followed by Klebsiella pneumoniae (16.4%. Prevalence of resistance for ciprofloxacin was higher compared to newer quinolones. Conclusions. E. coli and K. pneumoniae were the predominant bacterial etiologies; the prevalence of resistance to commonly prescribed antibiotics was high.

    Despite of a clearly defined diagnostic algorithm of pulmonary tuberculosis, low sensibility of contemporary laboratory methods in limited forms of pulmonary tuberculosis contributes to a difficult differential diagnosis with community acquired pneumonia, especially with slowly resolving pneumonia. A case-control, prospective, selective, comparative and descriptive study was performed using a group of 180 patients, divided into two samples: I group - 125 cases with limited form of pulmonary infiltrative tuberculosis; II group - 55 cases with slowly resolving community-acquired pneumonia. The findings identified the prevalence of intoxication syndrome in the slowly resolving pneumonia sample. Lung destructions and bronchogenous dissemination was identified only in the tuberculosis sample. A higher impact of comorbidities and old age was more relevant in slowly resolving pneumonia sample. Clinical and radiological improvement was established in most patients of both groups, but the considerable resorption of lung infiltrates predominated in slowly resolving pneumonia sample.

    The clonal spread of multiple drug-resistant Acinetobacter baumannii is an emerging problem in China. We analysed the molecular epidemiology of Acinetobacter baumanni isolates at three teaching hospitals and investigated the risk factors, clinical features, and outcomes of hospital-acquired pneumonia caused by extensive drug-resistant Acinetobacter baumannii (XDRAB) infection in Guangzhou, China. Fifty-two A. baumannii isolates were collected. Multilocus sequence typing (MLST) was used to assess the genetic relationships among the isolates. The bla OXA-51-like gene was amplified using polymerase chain reaction (PCR) and sequencing. The resistance phenotypes were determined using the disc diffusion method. A retrospective case-control study was performed to determine factors associated with XDRAB pneumonia. Most of the 52 A. baumannii isolates (N = 37, 71.2%) were collected from intensive care units (ICUs). The respiratory system was the most common bodily site from which A. baumannii was recovered (N = 45, 86.5%). Disc diffusion classified the isolates into 17 multidrug-resistant (MDR) and 35 extensively drug-resistant (XDR) strains. MLST grouped the A. baumannii isolates into 5 existing sequence types (STs) and 7 new STs. ST195 and ST208 accounted for 69.2% (36/52) of the isolates. The clonal relationship analysis showed that ST195 and ST208 belonged to clonal complex (CC) 92. According to the sequence-based typing (SBT) of the bla OXA-51-like gene, 51 A. baumannii isolates carried OXA-66 and the rest carried OXA-199. There were no significant differences with respect to the resistance phenotype between the CC92 and non-CC92 strains (P = 0.767). The multivariate analysis showed that the APACHE II score, chronic obstructive pulmonary disease (COPD) and cardiac disease were independent risk factors for XDRAB pneumonia (P < 0.05). The mortality rate of XDRAB pneumonia was high (up to 42.8%), but pneumonia caused by XDRAB was not associated with in-hospital

    Listeriosis is characterized by bacteremia or meningitis. We searched for listeriosis case series and outbreak investigations published in English by 2013, and assessed the strength of evidence for foodborne acquisition among patients who ate hospital food. We identified 30 reports from 13 countries. Among the case series, the median proportion of cases considered to be hospital-acquired was 25% (range, 9%-67%). The median number of outbreak-related illnesses considered to be hospital-acquired was 4.0 (range, 2-16). All patients were immunosuppressed in 18 of 24 (75%) reports with available data. Eight outbreak reports with strong evidence for foodborne acquisition in a hospital implicated sandwiches (3 reports), butter, precut celery, Camembert cheese, sausage, and tuna salad (1 report each). Foodborne acquisition of listeriosis among hospitalized patients is well documented internationally. The number of listeriosis cases could be reduced substantially by establishing hospital policies for safe food preparation for immunocompromised patients and by not serving them higher-risk foods.

    Intensive animal farming could potentially lead to outbreaks of infectious diseases. Clinicians are at the forefront of detecting unusual diseases, but the lack of specificity of zoonotic disease symptoms makes this a challenging task. We evaluated patients with community-acquired pneumonia (CAP) with known and unknown aetiology in an area with a high livestock density and a potential association with animal farms in the proximity. Between 2008 and 2009, a period coinciding with a large Q fever outbreak in the Netherlands, patients with CAP were tested for the presence of possible respiratory pathogens. The presence and number of farm animals within 1 km of the patients' home address were assessed using geographic information system (GIS) and were compared between cases and age-matched control subjects. Of 408 patients with CAP, pathogens were detected in 275 (67.4%) patients. The presence of sheep and the number of goats were associated with CAP caused by Coxiella burnetii in a multiple logistic regression model (P 0.10). The use of GIS in combination with aetiology of CAP could be potentially used to target diagnostics and to identify outbreaks of rare zoonotic disease. © 2015 Blackwell Verlag GmbH.

    Full Text Available Background: Appropriate and timely care seeking reduces mortality for childhood illnesses including pneumonia. Despite over 90 000 Lady Health Workers (LHWs deployed in Pakistan, whose tasks included management of pneumonia, only 16% of care takers sought care from them for respiratory infections. As part of a community case management trial for childhood pneumonia, community mobilization interventions were implemented to improve care seeking from LHWs in Haripur district, Pakistan. The objective of the study was to increase the number of children receiving treatment for pneumonia and severe pneumonia by Lady Health Workers (LHWs through community mobilization approaches for prompt recognition and care seeking in 2 to 59 month–old children. Methods: To assess pneumonia care seeking practices, pre and post– intervention household surveys were conducted in 28 target Union Councils. Formative research to improve existing LHW training materials, job aids and other materials was carried out. Advocacy events were organized, LHWs and male health promoters were trained in community mobilization, non–functional women and male health committees were revitalized and LHWs and male health promoters conducted community awareness sessions. Results: The community mobilization interventions were implemented from April 2008 – December 2009. Project and LHW program staff organized 113 sensitization meetings for opinion leaders, which were attended by 2262 males and 3288 females. The 511 trained LHWs organized 6132 community awareness sessions attended by 50 056 women and 511 male promoters conducted 523 sessions attended by 7845 males. In one year period, the number of LHWs treating pneumonia increased from 11 in April 2008 to 505 in March 2009. The care seeking from LHWs for suspected pneumonia increased from 0.7% in pre–intervention survey to 49.2% in post–intervention survey. Conclusion: The increase in care seeking from LHWs benefited the community

    Patients with healthcare-associated pneumonia (HCAP) are at high risk of infection with multidrug-resistant (MDR) pathogens. Factors discriminating infection with MDR Gram-negative (MDR-GN) organism from infection with methicillin-resistant Staphylococcus aureus (MRSA) are not well understood and patients are often treated for both organisms. This study was performed to determine risk factors predicting pneumonia due to Pseudomonas versus MRSA. Veterans age ≥65 hospitalized with HCAP between 2002 and 2012 were identified from the Veterans Affairs administrative databases. Patients were identified with Pseudomonas pneumonia, MRSA pneumonia or neither according to the International Classification of Diseases, 9th Revision, Clinical Modification codes. We assessed unadjusted and adjusted associations of patient characteristics and HCAP due to Pseudomonas or MRSA. Of the 61,651 patients with HCAP, 1156 (1.9%) were diagnosed with Pseudomonas pneumonia, 641 (1.0%) with MRSA pneumonia and 59,854 (97.1%) with neither. MRSA pneumonia was positively associated with male gender, age >74, diabetes, chronic obstructive pulmonary disease (COPD), recent nursing home or hospital stay, recent exposure to fluoroquinolone or antibiotics treating Gram-positive organisms, and severe pneumonia. MRSA pneumonia was negatively associated with complicated diabetes. Pseudomonas pneumonia was positively associated with recent hospital stay, immunocompromise, COPD, hemiplegia, recent exposure to inhaled corticosteroids, β-lactam/cephalosporin/carbapenem antibiotics, antibiotics against Gram-positive organisms, 'other antibiotics' and severe pneumonia. Pseudomonas pneumonia was negatively associated with age >84, higher socioeconomic status, drug abuse and diabetes. Patient characteristics may assist in identifying patients at risk for HCAP due to Pseudomonas or MRSA. © 2015 Asian Pacific Society of Respirology.

    BACKGROUND Pneumonia is one of the most common causes of death from infectious disease in the United States (US). Although most cases of community-acquired pneumonia (CAP) are secondary to bacterial infection, up to one-third of cases are secondary to viral infection, most commonly due to rhinovirus and influenza virus. Pneumonia due to herpes simplex virus (HSV) is rare, and there is limited knowledge of the pathogenesis and clinical complications. This report is of a fatal case of HSV pneumonia associated with bilateral pneumothorax and pneumomediastinum. CASE REPORT A 36-year-old homeless male Hispanic patient, who was a chronic smoker, with a history of intravenous drug abuse and a medical history of chronic hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infection, not on highly active antiretroviral therapy (HAART), was admitted to hospital as an emergency with a seven-day history of productive purulent cough. The patient was admitted to the medical intensive care unit (MICU) with a diagnosis of CAP, with intubation and mechanical ventilation. Broncho-alveolar lavage (BAL) was performed and was positive for HSV. The patient developed bilateral pneumothorax with pneumomediastinum, which was fatal, despite aggressive clinical management. CONCLUSIONS Pneumonia due to HSV infection is uncommon but has a high mortality. Although HSV pneumonia has been described in immunocompromised patients, further studies are required to determine the pathogenesis, early detection, identification of patients who are at risk and to determine the most effective approaches to prophylaxis and treatment for HSV pneumonia.

    Sputum microscopy and culture are commonly used for diagnosing the cause of pneumonia in adults but are rarely performed in children due to difficulties in obtaining specimens. Induced sputum is occasionally used to investigate lower respiratory infections in children but has not been widely used in pneumonia etiology studies. We evaluated the diagnostic utility of induced sputum microscopy and culture in patients enrolled in the Pneumonia Etiology Research for Child Health (PERCH) study, a large study of community-acquired pneumonia in children aged 1-59 months. Comparisons were made between induced sputum samples from hospitalized children with radiographically confirmed pneumonia and children categorized as nonpneumonia (due to the absence of prespecified clinical and laboratory signs and absence of infiltrate on chest radiograph). One induced sputum sample was available for analysis from 3772 (89.1%) of 4232 suspected pneumonia cases enrolled in PERCH. Of these, sputum from 2608 (69.1%) met the quality criterion of <10 squamous epithelial cells per low-power field, and 1162 (44.6%) had radiographic pneumonia. Induced sputum microscopy and culture results were not associated with radiographic pneumonia, regardless of prior antibiotic use, stratification by specific bacteria, or interpretative criteria used. The findings of this study do not support the culture of induced sputum specimens as a diagnostic tool for pneumonia in young children as part of routine clinical practice. © The Author 2017.

    Until recently, multiresistant bacteria were only limited to hospitals. However, they are now responsible for community acquired infections, affecting people who have had no contact with the hospital environment. Several mechanisms are associated with these resistances. The production of betalactamases is however the predominant mechanism and especially the production of extended spectrum beta-lactamases or ESBL by strains of Escherichia coli and Klebsiella pneumoniae, which mediate resistance to third generation cephalosporins and aztreonam (AZT). The association of multiple mechanisms of resistance (efflux pumps, impermeability and enzymatic inactivation) generates multi resistant bacteria such as Pseudomonas aeruginosa MDR and Klebsiella pneumoniae MDR. The aim of the study was to analyze retrospectively the susceptibility to antibiotics of strains of E. coli, K. pneumoniae, P. aeruginosa and A. baumanii isolated from hospitalized and outpatients in a university hospital center of Beirut over a period of five years from 2005 to 2009. Bacterial strains were classified according to their origin (inpatients versus outpatients), their ability to produce or not ESBLs for E. coli and K. pneumonia and if they were MDR for P. aeruginosa and A. baumanii. Antibiotics susceptibilities were retrieved from the informatics database of the hospital. Comparison of susceptibility percentages was done using a unilateral z-test on a computer program. In 2009, 2541 strains of E. coli were isolated, 773 of which or 30.4 % were ESBL producers while 2031 strains were isolated in 2005, of which 361 or 17.8 % were ESBL producers (pproducing strains between 2007 and 2009: 33.4 % versus 30.4 % (p=0.03). Among 560 strains of K. pneumoniae isolated in 2009, 178 strains or 31.8 % were ESBL producers in comparison to 23.7 % of the strains isolated in 2005 (p=0.03). We also noticed a decrease in hospital strains susceptibility to piperacilline-tazobactam (TZP), cefotaxime (CTX

    Carbapenem-resistant Enterobacteriaceae, especially Klebsiella spp., have become a major health problem recently worldwide. Since 2006 the incidence of carbapenem-resistant Klebsiella pneumoniae (CRKP) infections has increased substantially in Israel. Bloodstream infections (BSIs) caused by these strains have been associated with high rates of treatment failure and mortality. This study was designed to identify risk factors for carbapenem resistance among patients with healthcare-related (HCR) K. pneumoniae bacteraemia and predictors of mortality associated with HCR-CRKP bacteraemia compared with carbapenem-susceptible K. pneumoniae (CSKP). In this retrospective case-control study, all cases of K. pneumoniae bacteraemia during 2006-2008 were identified. Resistance patterns, underlying morbidities, risk factors for drug resistance and mortality rates were compared for patients with CRKP and CSKP bacteraemia. Two hundred and fourteen patients with CSKP bacteraemia were compared with 103 patients with CRKP bacteraemia. Severe, chronic comorbidities and prior antibiotic use were more frequent among patients with CRKP bacteraemia. On multivariate analysis prior use of macrolides and antibiotic exposure for ≥14 days remained the only independent factors associated with CRKP bacteraemia. Mortality rates of CRKP patients were significantly higher than those of CSKP patients. On multivariate analyses: bedridden status, chronic liver disease, Charlson comorbidity index ≥5, mechanical ventilation, and haemodialysis remained independently associated with mortality among patients with K. pneumoniae bacteraemia. Carbapenem resistance was not a risk factor for mortality. Previous antibiotic exposure is a risk factor for CRKP-BSI. Mortality among patients with K. pneumoniae bacteraemia is associated with serious comorbidities, but not with carbapenem resistance. Copyright © 2012 The Healthcare Infection Society.

    Background: Pneumonia is one of the leading causes of morbidity and mortality in children younger than 5 years of age. Zinc may have an important protective role in cases of childhood pneumonia. Objectives: To study the effect of zinc supplementation on duration of hospital stay in children (6 months to 5 years) with pneumonia. Methodology: This Randomized control trial was conducted in the Department of Paediatrics Unit - I, King Edward Medical University / Mayo Hospital, Lahore from January to December 2011. After consent, 150 children from 6 months to 5 years of age with pneumonia consistent with WHO ARI definition along with crepitations on auscultation were registered by non-probability purposive sampling and were randomized into treatment group (Group A) and placebo group (Group B). Seventy five children supplemented with zinc for 14 days while 75 children were supplemented with placebo. Outcome measure was duration of hospital stay. T-test was used to compare the groups. Results: Out of total study population of 150, majority (35%) of children were below 2 years. There was male predominance (64%). Mean duration of hospital stay was significantly reduced in treatment group (p value < 0.05). Conclusion: Zinc supplementation results in statistically significant reduction in the duration of hospital stay in children (6 months to 5 years) with pneumonia. (author)

Pneumonia was frequent in first-time exacerbations (36.1%, but declined in successive exacerbations to 25.6% by the seventh or greater exacerbation. Pneumonic COPD exacerbations increased 20% from 0.92 per 1,000 population in 2006 to 1.10 per 1,000 population in 2012. Nonpneumonic exacerbations decreased by 6% from 1.74 per 1,000 population to 1.63 per 1,000 population during the same period. A number of markers of health resource utilization were more prevalent in pneumonic exacerbations than in nonpneumonic exacerbations: length of stay (median 7 vs 4 days, intensive care unit admission (7.7% vs 12.5%, and several acute procedures. Thirty-day mortality was 12.1% in first-time pneumonic COPD exacerbations versus 8.3% in first-time nonpneumonic cases (adjusted HR [aHR] 1.20, 95% confidence interval [CI] 1.17–1.24.

    Full Text Available OBJECTIVE: The present study was undertaken to characterize CTX-M ESBL-producing Klebsiella pneumoniae collected from hospitals in different cities of Brazil. MATERIAL AND METHODS: Eighty-five K. pneumoniae strains isolated from hospitalized patients in six different hospitals of three cities of Brazil were analyzed. ESBL production was confirmed by the standard double-disk synergy test and the Etest®. The MIC50 and MIC90 for ESBL-producing isolates were determined by the Etest® method. The antimicrobial susceptibilities of bacterial isolates were determined using the agar diffusion method according to the CLSI. Screening for blaTEM, blaSHV, blaCTX-M genes and class 1 integron was performed by PCR amplification. To determine the genomic diversity of CTX-M-producers, isolates were analyzed by macrorestriction profile analysis following PFGE. RESULTS AND DISCUSSION: Seventy-one K. pneumoniae isolates were ESBL-producing. PCR and sequencing experiments detected 38 CTX-M-producing K. pneumoniae belonged to groups CTX-M 1, CTX-M 2, CTX-M 8 and CTX-M 9. The association of different types ESBL (CTX-M, SHV and TEM was frequent. All K. pneumoniae isolates carried class 1 integron. PFGE analysis revealed thirty-one clonal types among CTX-M-producing isolates. The data presented herein illustrate the diversity of genotypes of CTX-M producing K. pneumoniae among Brazilians hospitals.

    We evaluated pulmonologists variability in the interpretation of Vibration response imaging (VRI) obtained from healthy subjects and patients hospitalized for community acquired pneumonia. The present is a prospective study conducted in a tertiary university hospital. Twenty healthy subjects and twenty three pneumonia cases were included in this study. Six pulmonologists blindly analyzed images of normal subjects and pneumonia cases and evaluated different aspects of VRI images related to the quality of data aquisition, synchronization of the progression of breath sound distribution and agreement between the maximal energy frame (MEF) of VRI (which is the maximal geographical area of lung vibrations produced at maximal inspiration) and chest radiography. For qualitative assessment of VRI images, the raters' evaluations were analyzed by degree of consistency and agreement. The average value for overall identical evaluations of twelve features of the VRI image evaluation, ranged from 87% to 95% per rater (94% to 97% in control cases and from 79% to 93% per rater in pneumonia cases). Inter-rater median (IQR) agreement was 91% (82-96). The level of agreement according to VRI feature evaluated was in most cases over 80%; intra-class correlation (ICC) obtained by using a model of subject/rater for the averaged features was overall 0.86 (0.92 in normal and 0.73 in pneumonia cases). Our findings suggest good agreement in the interpretation of VRI data between different raters. In this respect, VRI might be helpful as a radiation free diagnostic tool for the management of pneumonia

    Full Text Available Hyponatremia (serum Na levels of <135 mEq/L is the most common electrolyte imbalance encountered in clinical practice, affecting up to 15–28% of hospitalized patients. This case report refers to a middle-aged man with severe hyponatremia due to Syndrome of Inappropriate Antidiuretic Hormone Secretion related to four possible etiological factors: glossopharyngeal squamous cell carcinoma, cisplatin treatment, right basal pneumonia with Pseudomonas aeruginosa, and the treatment with Levofloxacin. This case report discusses a rare complication of common conditions and of a common treatment. To our knowledge this is the first case of hyponatremia related to Levofloxacin and the second related to fluoroquinolones.

    Delirium is common in critically ill patients and impact in-hospital mortality in patients with pneumonia. The aim of the study was to evaluate the prevalence of delirium symptoms during hospitalization in patients with severe pneumonia and their impact on one-year mortality. This was an observational, retrospective, cohort study of consecutive patients admitted to the respiratory high dependency unit of the San Gerardo University Hospital, Monza, Italy, between January 2009 and December 2012 with a diagnosis of severe pneumonia. A search through the charts looking for ten key words associated with delirium (confusion, disorientation, altered mental status, delirium, agitation, inappropriate behavior, mental status change, inattention, hallucination, lethargy) was performed by a multidisciplinary team. The primary endpoint was mortality at one-year follow-up. Secondary endpoint was in-hospital mortality. A total of 172 patients were enrolled (78 % males; median age 75 years). At least one delirium symptom was detected in 53 patients (31 %) during hospitalization. The prevalence of delirium symptoms was higher among those who died during hospitalization vs. those who survived (44 vs. 27 %, p = 0.049, respectively). Seventy-one patients (46 %) died during the one-year follow-up. The prevalence of at least one delirium symptom was higher among those who died than those who survived during the one-year follow-up (39 vs. 21 %, p = 0.014, respectively). At the multivariable logistic regression analysis, after adjustment for age, comorbidities and severe sepsis, the presence of at least one delirium symptom during hospitalization was an independent predictor of one-year mortality (OR 2.35; 95 % CI 1.13-4.90; p = 0.023). Delirium symptoms are independent predictors of one-year mortality in hospitalized patients with severe pneumonia. Further studies should confirm our results using prospective methods of collecting data.
