    Gastroesophageal reflux disease (GERD) frequently occurs in association with chronic respiratory diseases although the casual link is not always clear. Several pathophysiological and experimental factors are considered to support a role for GERD in respiratory disease. Conversely, respiratory diseases and bronchodilator treatment can themselves exacerbate GERD. When cough or severe asthma is being investigated, GERD does not need to be systematically looked for and a therapeutic test with proton pump inhibitors is not always recommended. pH impedance monitoring is now the reference diagnostic tool to detect non acid reflux, a form of reflux for which proton pump inhibitor treatment is ineffective. Recent data have shown a potential role of GERD in idiopathic pulmonary fibrosis and bronchiolitis obliterans following lung transplantation, leading to discussions about the place of surgery in this context. However, studies using pH impedance monitoring are still needed to better understand and manage the association between GERD and chronic respiratory diseases.

    Chronic obstructive pulmonary disease (COPD) is defined as persistent airflow limitation due to irritant-induced chronic inflammation. A postbronchodilator forced expiratory volume in 1 second to forced vital capacity (FEV1/FVC) ratio of 0.7 or less is diagnostic in a patient with dyspnea, chronic cough or sputum production, and a history of irritant exposure. Tobacco smoking is the most significant etiology, and smoking cessation is the only intervention shown to slow disease progression. Long-acting beta2-agonists and long-acting muscarinic antagonists are first-line treatments for patients with persistently symptomatic COPD with an FEV1 of 80% or less of predicted. When COPD is uncontrolled with a long-acting bronchodilator, combination therapy with a long-acting muscarinic antagonist-long-acting beta2-agonist or long-acting beta2-agonist-inhaled corticosteroid should be prescribed. Patients with COPD and reduced exercise tolerance should undergo pulmonary rehabilitation and be evaluated for supplemental oxygen therapy. Other treatment options for persistently symptomatic COPD include inhaler triple therapy (ie, long-acting muscarinic antagonist, long-acting beta2-agonist, inhaled corticosteroid), phosphodiesterase type 4 inhibitors, oxygen, and surgical interventions.

    The literature lacks reports on the role of the social relationships domain (SRD) of quality of life (QoL) in shaping care for patients with chronic respiratory diseases in primary care. In this study we examined a group of 582 patients with chronic respiratory diseases and chronic non-respiratory diseases recruited from 199 primary care centers. In the patients with chronic respiratory diseases, higher SRD correlated with more frequent patient visits due to medical issue, fewer district nurse interventions over the past 12 months, less frequent hospitalizations over the past 3 years, and fewer chronic diseases. In these patients, a high SRD was most effectively created by high QoL in the Psychological, Environmental, and Physical domains, and the satisfaction with QoL. Programs for preventing a decline in SRD should include patients with low scores in the Psychological, Environmental, and Physical domains, those who show no improvement in mental or somatic well-being in the past 12 months, those with a low level of positive mental attitudes, unhealthy eating habits, and with low levels of met needs. Such programs should include older widows and widowers without permanent relationships, with only primary education, living far from a primary care center, and those whose visits were not due to a medical issue.

    BACKGROUND: Many patients with chronic obstructive lung disease show increased airways responsiveness to histamine. We investigated the hypothesis that increased airways responsiveness predicts the development and remission of chronic respiratory symptoms. METHODS: We used data from 24-year follow......-up (1965-90) of 2684 participants in a cohort study in Vlagtwedde and Vlaardingen, Netherlands. Increased airways responsiveness was defined as a PC10 value (concentration of histamine for which challenge led to a 10% fall in forced expiratory volume in 1 s) of less than 8 mg/ml. Information on respiratory...... of the odds ratio for the development of any of the six symptoms was 1.7 (1.2-2.3). Participants with increased airways responsiveness were less likely than those without this characteristic to show remission of these respiratory symptoms.

    Full Text Available In developed countries, it is very difficult to demonstrate the effectiveness of pneumococcal vaccines because the incidence of pneumococcal pneumonia is very low. Vaccination against pneumococci infection was advised for 1378 outpatients, over 60 years of age, with chronic respiratory disease for more than one year. Of these patients, those who responded affirmatively to the advice were vaccinated against pneumococci between August and November 2002. The effectiveness of vaccination was evaluated by means of a 2-year cohort-study, comparing the vaccinated group (647 with the non-vaccinated group (731. The variables analyzed were the frequency of onset of bacterial respiratory infection, hospitalization due to bacterial respiratory infection and onset of pneumococcal respiratory infection. The incidence of bacterial respiratory infection and the incidence of pneumococcal respiratory infection to have decreased in the following 2 years (17.4%, 0.9%, as compared to the previous year (25.9%, 3.1%, in the vaccinated group. Conversely, the frequency was higher in the following 2 years (14.4%, 0.9% as compared to the previous year (14.2%, 0.4% in the non-vaccinated group. This inter-group difference was statistically significant. Simultaneous vaccination against pneumococci and influenza virus also resulted in a significant reduction in the incidence of bacterial respiratory infection. No decrease was observed in the frequency of hospitalization. These results indicate that pneumococcal vaccine is useful for elderly patients with chronic respiratory disease and that its efficacy may be enhanced by simultaneous vaccination against influenza.

    Pneumococcal vaccination is still rare in Japan. To evaluate understanding concerning the vaccination, we employed a questionnaire answered by patients aged over 60 with chronic respiratory diseases from August to October 2002. Only 286 (18%) of the 1595 patients already knew of the existence of the vaccine, and 999 (64%) patients wanted to be vaccinated. That season, 717 (43%) patients were actually vaccinated. Patients with chronic respiratory failure, those who had contracted pulmonary infections in the previous year, those over 70 year-old, and male patients tended to be vaccinated. Although elderly and high-risk patients are recommended to be vaccinated, the pneumococcal vaccination rates in those patients was low. Campaigns for vaccination are needed.

    Objective: Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) cause significant morbidity, mortality, and an inexorable decline of lung function. Data from developed countries have shown viruses to be important causes of AECOPD, but data from developing countries like India are scant. We set out to determine the contribution of viruses in the causation of hospitalized patients with AECOPD. Methods: Twin nasopharyngeal/oropharyngeal swabs collected from 233 patients admitted with an acute AECOPD and tested for respiratory viruses including respiratory syncytial virus A and B, parainfluenza were (PIV) 1, 2, 3, and 4, human metapneumovirus (hMPV) A and B, influenza A and B, enterovirus, corona NL65, OC43, and 229E viruses, adenovirus 2 and 4, rhinovirus, and bocavirus, by duplex real time reverse-transcription polymerase chain reaction (qRT-PCR) using CDC approved primers and probes. Samples positive for influenza A were subtyped for A/H1N1pdm09 and A/H3N2 whereas influenza B samples were subtyped into B/Yamagata and B/Victoria subtypes, using primers and probes recommended by CDC, USA. Results: Respiratory viruses were detected in 46 (19.7%) cases, influenza A/H3N2 and rhinoviruses being the most common viruses detected. More than one virus was isolated in four cases consisting of hMPV-B + adeno-2 + Inf-B; rhino + H3N2, PIV-1 + rhino; and PIV-1+ hMPV-B in one case each. Ancillary supportive therapeutic measures included bronchodilators, antibiotics, steroids, and ventilation (noninvasive in 42 and invasive in 4). Antiviral therapy was instituted in influenza-positive patients. Three patients with A/H3N2 infection died during hospitalization. Conclusions: We conclude that respiratory viruses are important contributors to AECOPD in India. Our data calls for prompt investigation during an exacerbation for viruses to obviate inappropriate antibiotic use and institute antiviral therapy in viral disease amenable to antiviral therapy.

    Full Text Available Chronic Respiratory Disease (CRD is a publichealth problem in Colombia. Its severity increasesby the presence of risk factors like firesmoke, which tend to prevail in young populationand that leads consequences at physical,social and mental level in the long run. The CRDincludes a series of clinical entities with theirown characteristics, caused by the suffering, socialisolation, physiological deterioration andthe associated morbidity. All these contributeto the functional limitation, the lost quality oflife and, ultimately, can turn the individual thatsuffers it in a dependent being without future.All this takes to a greater consumption of healthresources without this means one better attention,since in many opportunities the isolated efforts, the lack of clear rules, sustained proposalsand the non use of clinical guidelines amongother causes, allow that the intervention wouldbe destined to only palliate the present symptoms,but is far from including an integral, effectivehandling and that responds to individualnecessities.

    Full Text Available OBJECTIVE: Recent work has suggested that within-breath respiratory impedance measurements performed using the forced oscillation technique may help to noninvasively evaluate respiratory mechanics. We investigated the influence of airway obstruction on the within-breath forced oscillation technique in smokers and chronic obstructive pulmonary disease patients and evaluated the contribution of this analysis to the diagnosis of chronic obstructive pulmonary disease. METHODS: Twenty healthy individuals and 20 smokers were assessed. The study also included 74 patients with stable chronic obstructive pulmonary disease. We evaluated the mean respiratory impedance (Zm as well as values for the inspiration (Zi and expiration cycles (Ze at the beginning of inspiration (Zbi and expiration (Zbe, respectively. The peak-to-peak impedance (Zpp=Zbe-Zbi and the respiratory cycle dependence (ΔZrs=Ze-Zi were also analyzed. The diagnostic utility was evaluated by investigating the sensitivity, the specificity and the area under the receiver operating characteristic curve. ClinicalTrials.gov: NCT01888705. RESULTS: Airway obstruction increased the within-breath respiratory impedance parameters that were significantly correlated with the spirometric indices of airway obstruction (R=−0.65, p90%. CONCLUSIONS: We conclude the following: (1 chronic obstructive pulmonary disease introduces higher respiratory cycle dependence, (2 this increase is proportional to airway obstruction, and (3 the within-breath forced oscillation technique may provide novel parameters that facilitate the diagnosis of respiratory abnormalities in chronic obstructive pulmonary disease.

    There are scarce reports in the literature on factors affecting the assessment of the quality of care for patients with chronic respiratory diseases. Such information is relevant in the accreditation process on implementing the healthcare. The study group consisted of 133 adult patients with chronic respiratory diseases and 125 adult patients with chronic non-respiratory diseases. In the present study, the level of satisfaction from healthcare provided by the primary healthcare unit, disease acceptance, quality of life, health behaviors, and met needs were examined, as well as associations between variables with the use of correspondence analysis. The results are that in patients with chronic respiratory diseases an increase in satisfaction depends on the improvement of well-being in the mental sphere. The lack of problems with obtaining a referral to a specialist and a higher level of fulfilled needs also have a positive effect. Additionally, low levels of satisfaction should be expected in those patients with chronic respiratory diseases who wait for an appointment in front of the office for a long time, report problems with obtaining a referral to additional tests, present a low level of health behaviors, and have a low index of benefits.

    To understand the pathogenesis of chronic inflammatory disease, we analyzed an experimental mouse model of chronic lung disease with pathology that resembles asthma and chronic obstructive pulmonary disease (COPD) in humans. In this model, chronic lung disease develops after an infection with a common type of respiratory virus is cleared to only trace levels of noninfectious virus. Chronic inflammatory disease is generally thought to depend on an altered adaptive immune response. However, here we find that this type of disease arises independently of an adaptive immune response and is driven instead by interleukin-13 produced by macrophages that have been stimulated by CD1d-dependent T cell receptor-invariant natural killer T (NKT) cells. This innate immune axis is also activated in the lungs of humans with chronic airway disease due to asthma or COPD. These findings provide new insight into the pathogenesis of chronic inflammatory disease with the discovery that the transition from respiratory viral infection into chronic lung disease requires persistent activation of a previously undescribed NKT cell-macrophage innate immune axis.

    Chronic obstructive pulmonary disease and asthma impose a substantial burden of disease. This narrative review focuses on potential population-wide interventions that are likely to have an impact on these diseases. The developmental origins of adult disease commence in utero, with maternal nutrition being of particular interest. However, to date, trials of maternal allergen avoidance, dietary supplementation or probiotics have not shown consistent protective effects against asthma. Poor indoor air quality, especially from biomass fuels as well as second-hand tobacco smoke, is a well-recognised risk factor for chronic respiratory diseases. This can be modified by cleaner fuels, cooking stoves or heaters, and improved ventilation. Although allergens are a risk factor for childhood asthma, the results of interventions to reduce exposures have been disappointing. Traffic-related air pollution is associated with an increased incidence of asthma in children. Primary prevention of the adverse effects of air pollution has focused on the development of ambient air quality guidelines, but enforcement remains a challenge in many countries. Occupational asthma may be induced by sensitisers or irritants in the workplace. Prevention involves eliminating the agent or reducing exposure as far as possible, which is more effective than respiratory protective equipment. Smoking cessation remains a key proven preventive strategy for chronic respiratory diseases. There is now an international framework for tobacco control, and recent innovations include plain packaging of tobacco. Chronic respiratory diseases can be substantially prevented by the above population-wide interventions.

  19. High rates of detection of respiratory viruses in tonsillar tissues from children with chronic adenotonsillar disease.

    Jose Luiz Proenca-Modena

    Full Text Available Chronic tonsillar diseases are an important health problem, leading to large numbers of surgical procedures worldwide. Little is known about pathogenesis of these diseases. In order to investigate the role of respiratory viruses in chronic adenotonsillar diseases, we developed a cross-sectional study to determine the rates of viral detections of common respiratory viruses detected by TaqMan real time PCR (qPCR in nasopharyngeal secretions, tonsillar tissues and peripheral blood from 121 children with chronic tonsillar diseases, without symptoms of acute respiratory infections. At least one respiratory virus was detected in 97.5% of patients. The viral co-infection rate was 69.5%. The most frequently detected viruses were human adenovirus in 47.1%, human enterovirus in 40.5%, human rhinovirus in 38%, human bocavirus in 29.8%, human metapneumovirus in 17.4% and human respiratory syncytial virus in 15.7%. Results of qPCR varied widely between sample sites: human adenovirus, human bocavirus and human enterovirus were predominantly detected in tissues, while human rhinovirus was more frequently detected in secretions. Rates of virus detection were remarkably high in tonsil tissues: over 85% in adenoids and close to 70% in palatine tonsils. In addition, overall virus detection rates were higher in more hypertrophic than in smaller adenoids (p = 0.05, and in the particular case of human enteroviruses, they were detected more frequently (p = 0.05 in larger palatine tonsils than in smaller ones. While persistence/latency of DNA viruses in tonsillar tissues has been documented, such is not the case of RNA viruses. Respiratory viruses are highly prevalent in adenoids and palatine tonsils of patients with chronic tonsillar diseases, and persistence of these viruses in tonsils may stimulate chronic inflammation and play a role in the pathogenesis of these diseases.

    2011-12-01

    Until recently, relationships between evidence of colonization or infection by specific microbial species and the development, persistence or exacerbation of pulmonary disease have informed our opinions of airway microbiology. However, recent applications of culture-independent tools for microbiome profiling have revealed a more diverse microbiota than previously recognized in the airways of patients with chronic pulmonary disease. New evidence indicates that the composition of airway microbiota differs in states of health and disease and with severity of symptoms and that the microbiota, as a collective entity, may contribute to pathophysiologic processes associated with chronic airway disease. Here, we review the evolution of airway microbiology studies of chronic pulmonary disease, focusing on asthma, chronic obstructive pulmonary disease and cystic fibrosis. Building on evidence derived from traditional microbiological approaches and more recent culture-independent microbiome studies, we discuss the implications of recent findings on potential microbial determinants of respiratory health or disease.

    Background Poor uptake and adherence are problematic for hospital-based pulmonary and heart failure rehabilitation programs, often because of access difficulties. The aims of this mixed-methods study were to determine the feasibility of a supervised exercise training program in a community gymnasium in people with chronic respiratory and chronic cardiac disease, to explore the experiences of participants and physiotherapists and to determine if a community venue improved access and adherence to rehabilitation. Methods Adults with chronic respiratory and/or chronic cardiac disease referred to a hospital-based pulmonary and heart failure rehabilitation program were screened to determine their suitability to exercise in a community venue. Eligible patients were offered the opportunity to attend supervised exercise training for 8 weeks in a community gymnasium. Semi-structured interviews were conducted with participants and physiotherapists at the completion of the program. Results Thirty-one people with chronic respiratory and chronic cardiac disease (34% males, mean [standard deviation] age 72 [10] years) commenced the community-based exercise training program. Twenty-two (71%) completed the program. All participants who completed the program, and the physiotherapists delivering the program, were highly satisfied, with reports of the community venue being well-equipped, convenient, and easily accessible. Using a community gymnasium promoted a sense of normality and instilled confidence in some to continue exercising at a similar venue post rehabilitation. However, factors such as cost and lack of motivation continue to be barriers. Conclusion The convenience and accessibility of a community venue for rehabilitation contributed to high levels of satisfaction and a positive experience for people with chronic respiratory and chronic cardiac disease and physiotherapists.

    Dyspnea and exercise limitation are among the most common symptoms experienced by patients with various chronic lung diseases and are linked to poor quality of life. Our understanding of the source and nature of perceived respiratory discomfort and exercise intolerance in chronic lung diseases has increased substantially in recent years. These new mechanistic insights are the primary focus of the current review. Cardiopulmonary exercise testing (CPET) provides a unique opportunity to objectively evaluate the ability of the respiratory system to respond to imposed incremental physiological stress. In addition to measuring aerobic capacity and quantifying an individual's cardiac and ventilatory reserves, we have expanded the role of CPET to include evaluation of symptom intensity, together with a simple “non-invasive” assessment of relevant ventilatory control parameters and dynamic respiratory mechanics during standardized incremental tests to tolerance. This review explores the application of the new advances in the clinical evaluation of the pathophysiology of exercise intolerance in chronic obstructive pulmonary disease (COPD), chronic asthma, interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH). We hope to demonstrate how this novel approach to CPET interpretation, which includes a quantification of activity-related dyspnea and evaluation of its underlying mechanisms, enhances our ability to meaningfully intervene to improve quality of life in these pathologically-distinct conditions.

  4. Microbial communities in the upper respiratory tract of patients with asthma and chronic obstructive pulmonary disease.

    HeeKuk Park

    Full Text Available Respiratory infections are well-known triggers of chronic respiratory diseases. Recently, culture-independent tools have indicated that lower airway microbiota may contribute to pathophysiologic processes associated with asthma and chronic obstructive pulmonary disease (COPD. However, the relationship between upper airway microbiota and chronic respiratory diseases remains unclear. This study was undertaken to define differences of microbiota in the oropharynx of asthma and COPD patients relative to those in healthy individuals. To account for the qualitative and quantitative diversity of the 16S rRNA gene in the oropharynx, the microbiomes of 18 asthma patients, 17 COPD patients, and 12 normal individuals were assessed using a high-throughput next-generation sequencing analysis. In the 259,572 total sequence reads, α and β diversity measurements and a generalized linear model revealed that the oropharynx microbiota are diverse, but no significant differences were observed between asthma and COPD patients. Pseudomonas spp. of Proteobacteria and Lactobacillus spp. of Firmicutes were highly abundant in asthma and COPD. By contrast, Streptococcus, Veillonella, Prevotella, and Neisseria of Bacteroidetes dominated in the healthy oropharynx. These findings are consistent with previous studies conducted in the lower airways and suggest that oropharyngeal airway microbiota are important for understanding the relationships between the various parts of the respiratory tract with regard to bacterial colonization and comprehensive assessment of asthma and COPD.

Methods Six hundred and ninety three patients hospitalized from 2010 to 2013 were classified by echocardiography according to pulmonary arterial systolic pressure (PASP): mild (36≤ PASP 20 mm) were associated with moderate-to-severe PH, while RV [odds ratio (OR) =3.53, 95% CI, 2.17–5.74], NT-proBNP (OR=2.44, 95% CI, 1.51–3.95), HCT (OR=1.03, 95% CI, 1.00–1.07) and PaCO2 (OR=1.01, 95% CI, 1.00–1.03) were independent risk factors. Conclusions PH related to respiratory diseases is mostly mild to moderate, and the severity is associated with the category of respiratory disease. Increased HCT can be an independent risk factor for PH related to chronic respiratory diseases. PMID:27076929

    Chronic obstructive respiratory disorders such as asthma and chronic obstructive pulmonary disease often originate early in life. In addition to a genetic predisposition, prenatal and early-life environmental exposures have a persistent impact on respiratory health. Acting during a critical phase of lung development, these factors may change lung structure and metabolism, and may induce maladaptive responses to harmful agents, which will affect the whole lifespan. Some environmental factors, such as exposure to cigarette smoke, type of childbirth and diet, may be modifiable, but it is more difficult to influence other factors, such as preterm birth and early exposure to viruses or allergens. Here, we bring together recent literature to analyse the critical aspects involved in the early stages of lung development, going back to prenatal and perinatal events, and we discuss the mechanisms by which noxious factors encountered early on may have a lifelong impact on respiratory health. We briefly comment on the need for early disease biomarkers and on the possible role of "-omic" technologies in identifying risk profiles predictive of chronic respiratory conditions. Such profiles could guide the ideation of effective preventive strategies and/or targeted early lifestyle or therapeutic interventions.

    Full Text Available Dyspnoea, fatigue, reduced exercise tolerance, peripheral muscle dysfunction and mood disorders are common features of many chronic respiratory disorders. Pulmonary rehabilitation successfully treats these manifestations in chronic obstructive pulmonary disease (COPD and emerging evidence suggests that these benefits could be extended to other chronic respiratory conditions, although adaptations to the standard programme format may be required. Whilst the benefits of exercise training are well established in asthma, pulmonary rehabilitation can also provide evidence-based interventions including breathing techniques and self-management training. In interstitial lung disease, a small number of trials show improved exercise capacity, symptoms and quality of life following pulmonary rehabilitation, which is a positive development for patients who may have few treatment options. In pulmonary arterial hypertension, exercise training is safe and effective if patients are stable on medical therapy and close supervision is provided. Pulmonary rehabilitation for bronchiectasis, including exercise training and airway clearance techniques, improves exercise capacity and quality of life. In nonsmall cell lung cancer, a comprehensive interdisciplinary approach is required to ensure the success of pulmonary rehabilitation following surgery. Pulmonary rehabilitation programmes provide important and underutilised opportunities to improve the integrated care of people with chronic respiratory disorders other than COPD.

    This study evaluated the risk of outpatient visits for respiratory diseases, asthma, and chronic airway obstruction not elsewhere classified (CAO) associated with ambient temperatures and extreme temperature events from 2000 to 2008 in Taiwan. Based on geographical and socioeconomics characteristics, this study divided the whole island into seven areas. A distributed lag non-linear model was used to estimate the area-disease-specific cumulative relative risk (RR), and random-effect meta-analysis was used to estimate the pooled RR of outpatient visits, from lag 0 to lag 7 days, associated with daily temperature, and added effects of prolonged extreme heat and cold for population of all ages, the elderly and younger than 65 years. Pooled analyses showed that younger population had higher outpatient visits for exposing to low temperature of 18 °C, with cumulative 8-day RRs of 1.36 (95 % confidence interval (CI) 1.31-1.42) for respiratory diseases, 1.10 (95 % CI 1.03-1.18) for asthma, and 1.12 (95 % CI 1.02-1.22) for CAO. The elderly was more vulnerable to high temperature of 30 °C with the cumulative 8-day RR of 1.08 (95 % CI 1.03-1.13) for CAO. Elevated outpatient visits for all respiratory diseases and asthma were associated with extreme heat lasting for 6 to 8 days. On the contrary, the extreme cold lasting more than 8 days had significant negative association with outpatient visits of all respiratory diseases. In summary, elderly patients of respiratory diseases and CAO are vulnerable to high temperature. Cold temperature is associated with all types of respiratory diseases for younger patients.

The aims of this mixed-methods study were to determine the feasibility of a supervised exercise training program in a community gymnasium in people with chronic respiratory and chronic cardiac disease, to explore the experiences of participants and physiotherapists and to determine if a community venue improved access and adherence to rehabilitation. Methods: Adults with chronic respiratory and/or chronic cardiac disease referred to a hospital-based pulmonary and heart failure rehabilitation program were screened to determine their suitability to exercise in a community venue. Eligible patients were offered the opportunity to attend supervised exercise training for 8 weeks in a community gymnasium. Semi-structured interviews were conducted with participants and physiotherapists at the completion of the program. Results: Thirty-one people with chronic respiratory and chronic cardiac disease (34% males, mean [standard deviation] age 72 [10] years commenced the community-based exercise training program. Twenty-two (71% completed the program. All participants who completed the program, and the physiotherapists delivering the program, were highly satisfied, with reports of the community venue being well-equipped, convenient, and easily accessible. Using a community gymnasium promoted a sense of normality and instilled confidence in some to continue exercising at a similar venue post rehabilitation. However, factors such as cost and lack of motivation continue to be barriers

    Full Text Available No abstract available. Article truncated after 150 words. This month's journal club reviewed the role of macrolide antibiotics in chronic respiratory disease. Macrolide usage was suggested from observational studies in Japan in diffuse panbroncholitis, a disorder associated with chronic respiratory infection, usually Pseudomonas aeruginosa (1. Clinical improvement was noted despite doses of antibiotics well below the minimal inhibitory concentration (MIC of the antibiotic. This suggested the antibiotic was likely working by an anti-inflammatory effect. These observations were extended to cystic fibrosis (CF where prophylactic macrolide therapy in CF patients infected with Pseudomonas has become standard therapy (2. More recently, low dose macrolide therapy has been applied to non-CF lung diseases such as chronic obstructive pulmonary disease (COPD, bronchiectasis and asthma. Time did not permit a review of all studies so a representative sample was discussed. In patients with COPD, the four randomized, placebo-controlled trials reviewed all suggested that chronic therapy with macrolide antibiotics reduced COPD exacerbations (3-5. This ...

    Breathing involves a complex interplay between the brainstem automatic network and cortical voluntary command. How these brain regions communicate at rest or during inspiratory loading is unknown. This issue is crucial for several reasons: (i) increased respiratory loading is a major feature of several respiratory diseases, (ii) failure of the voluntary motor and cortical sensory processing drives is among the mechanisms that precede acute respiratory failure, (iii) several cerebral structures involved in responding to inspiratory loading participate in the perception of dyspnea, a distressing symptom in many disease. We studied functional connectivity and Granger causality of the respiratory network in controls and patients with chronic obstructive pulmonary disease (COPD), at rest and during inspiratory loading. Compared with those of controls, the motor cortex area of patients exhibited decreased connectivity with their contralateral counterparts and no connectivity with the brainstem. In the patients, the information flow was reversed at rest with the source of the network shifted from the medulla towards the motor cortex. During inspiratory loading, the system was overwhelmed and the motor cortex became the sink of the network. This major finding may help to understand why some patients with COPD are prone to acute respiratory failure. Network connectivity and causality were related to lung function and illness severity. We validated our connectivity and causality results with a mathematical model of neural network. Our findings suggest a new therapeutic strategy involving the modulation of brain activity to increase motor cortex functional connectivity and improve respiratory muscles performance in patients.

    To evaluate effectiveness of pneumococcal polysaccharide vaccine, we recommended 1378 outpatients aged over 60 with chronic respiratory diseases to be vaccinated from August to October 2002, and 647 patients were vaccinated from August to November 2002. In the 1229 patients without respiratory failure, the incidence of antimicrobial treatment for bacterial respiratory infections in 547 vaccinated patients significantly decreased from 7.9% in the 2001/02 winter season to 5.7% in the 2002/03 winter season, although that in the 682 unvaccinated patients increased from 3.8% to 5.7%. The incidence of antimicrobial treatment for bacterial respiratory infections in 229 vaccinated patients with pneumococcal and influenza vaccines together significantly decreased from 10.5% in the 2001/02 winter season to 5.2% in 2002/03 winter season although that in 110 subjects vaccinated with influenza vaccine only increased from 2.7% to 7.2%. These findings suggest the effectiveness of the pneumococcal polysaccharide vaccine for the prevention of bacterial respiratory infections and the additive effectiveness of pneumococcal and influenza vaccines together.

  14. Persistent and Recurrent Bacterial Bronchitis—A Paradigm Shift in Our Understanding of Chronic Respiratory Disease

    The recent recognition that the conducting airways are not “sterile” and that they have their own dynamic microbiome, together with the rapid advances in our understanding of microbial biofilms and their roles in the causation of respiratory diseases (such as chronic bronchitis, sinusitis, and chronic otitis media), permit us to update the “vicious circle” hypothesis of the causation of bronchiectasis. This proposes that chronic inflammation driven by persistent bacterial bronchitis (PBB) causes damage to both the epithelium, resulting in impaired mucociliary clearance, and to the airway wall, which eventually manifests as bronchiectasis. The link between a “chronic bronchitis” and a persistence of bacterial pathogens, such as non-typable Haemophilus influenzae, was first made more than 100 years ago, and its probable role in the causation of bronchiectasis was proposed soon afterward. The recognition that the “usual suspects” are adept at forming biofilms and hence are able to persist and dominate the normal dynamically changing “healthy microbiome” of the conducting airways provides an explanation for the chronic colonization of the bronchi and for the associated chronic neutrophil-dominated inflammation characteristic of a PBB. Understanding the complex interaction between the host and the microbial communities of the conducting airways in health and disease will be a key component in optimizing pulmonary health in the future.

  19. The role of invasive ventilation in exacerbations of chronic obstructive pulmonary disease causing respiratory failure.

    2006-01-01

    Acute hypercapnic respiratory failure in chronic obstructive pulmonary disease can usually be managed initially with medical treatment and non- invasive ventilation. In circumstances where non- invasive ventilation cannot be used or has failed, intubation and invasive ventilation may be lifesaving. The outcome of patients with an exacerbation of COPD requiring invasive ventilation is better than often thought, with a hospital survival of 70-89%. Decisions regarding invasive ventilation made by physicians and patients with COPD are unpredictable and vary with the individual. This article reviews the role of invasive ventilation in exacerbations of COPD to assist decision making.

    Neuromuscular diseases affect alveolar air exchange and therefore cause chronic respiratory failure. The onset of respiratory failure can be acute, as in traumas, or progressive (slow or rapid), as in amyotrophic lateral sclerosis, muscular dystrophies, diseases of the myoneural junction, etc. Respiratory muscle impairment also affects cough efficiency and, according to the current knowledge regarding the type of treatment available in Brazil to these patients, it can be said that the high rates of morbidity and mortality in these individuals are more often related to the fact that they cough inefficiently rather than to the fact that they ventilate poorly. In this review, with the objective of presenting the options of devices available to support and substitute for natural ventilation in patients with neuromuscular diseases, we have compiled a brief history of the evolution of orthopedic braces and prostheses used to aid respiration since the end of the 19th century. In addition, we highlight the elements that are fundamental to the diagnosis of alveolar hypoventilation and of failure of the protective cough mechanism: taking of a clinical history; determination of peak cough flow; measurement of maximal inspiratory and expiratory pressures; spirometry in two positions (sitting and supine); pulse oximetry; capnography; and polysomnography. Furthermore, the threshold values available in the literature for the use of nocturnal ventilatory support and for the extension of this support through the daytime period are presented. Moreover, the maneuvers used to increase cough efficiency, as well as the proper timing of their introduction, are discussed.

    An epidemiologic research together with a study on the environmental pollution were carried out in order to evaluate the risk of chronic respiratory diseases of blast furnace workers. The environment study was performed mainly using personal samplers given to workers with different jobs. Observations on 222 work shifts have shown that the total dust concentration to which cast workmen, maintenance men and blast furnace service men were exposed, marginally exceed the TLV values. Furthermore the level of respirable dusts for blast furnace service men was found slightly excessive. The average SO2 concentration was largely below the TLV values. However this gas could be found in excess for very short periods during the work. The epidemiologic study, conducted on a cohort of blast furnace area workers against a control group cohort, indicated a moderate prevalence of pneumoconiosis and chronic bronchitis amongst blast furnaces workers. The clinic and radiological pictures do not seem to go beyond the initial stages.

  2. Recommendations for Patients with Chronic Respiratory Disease Considering Air Travel: A Statement from the Canadian Thoracic Society

    Full Text Available Patients with respiratory disease regularly seek the convenience of commercial airline travel. In addition to the stresses that all patients with chronic disease encounter, these patients are exposed to the affects of acute altitudinal hypoxemia. This in turn has the potential to produce significant symptoms and complications in-flight for patients with chronic respiratory disease. This article reviews the current literature, and seeks to help the practicing physician by providing recommendations on which patients should be assessed preflight, the type of assessment that should be carried out and recommendations for providing advice to these travelling patients.

    Full Text Available OBJECTIVE: Respiratory muscle weakness is a functional repercussion of chronic lung disease (CLD. The objective of this study was to assess the effects of home-based respiratory muscle training (RMT in children and adolescents with CLD or neuromuscular disease (NMD. METHODS: This was a quasi-experimental study involving children and adolescents with CLD or NMD. Before and after 6 months of home-based RMT, we measured respiratory muscle strength (MIP and MEP, PEF, and peak cough flow (PCF. We made statistical comparisons between the pre-RMT and post-RMT values, as well as evaluating the correlation between the duration and effect of RMT. RESULTS: The study included 29 patients, with a mean age of 12 years (range, 5-17 years, of whom 18 (62.1% were male. The CLD group comprised 11 patients (37.9%, and the NMD group comprised 18 (62.1%. The mean duration of the RMT was 60 weeks (range, 46-90 weeks in the CLD group and 39 weeks (range, 24-89 weeks in the NMD group. In comparison with the pre-RMT values, the post-RMT values for MIP and MEP were significantly higher in both groups, whereas those for PEF and PCF were significantly higher only in the NMD group. We found no correlation between the duration and the effect of RMT. CONCLUSIONS: Home-based RMT appears to be an effective strategy for increasing respiratory muscle strength in children and adolescents with CLD or NMD, although it increased the ability to cough effectively only in those with NMD.

    Full Text Available BACKGROUND: A synchronism exists between the respiratory and cardiac cycles. However, the influence of the inspiratory muscle weakness in chronic obstructive pulmonary disease (COPD on cardiac autonomic control is unknown. The purpose of the present investigation was to evaluate the influence of respiratory muscle strength on autonomic control in these patients. METHODS: Ten chronic obstructive pulmonary disease patients (69±9 years; FEV1/FVC 59±12% and FEV1 41±11% predicted and nine age-matched healthy volunteers (64±5 years participated in this study. Heart-rate variability (HRV was obtained at rest and during respiratory sinusal arrhythmia maneuver (RSA-M by electrocardiograph. RESULTS: Chronic obstructive pulmonary disease patients demonstrated impaired cardiac autonomic modulation at rest and during RSA-M when compared with healthy subjects (p<0.05. Moreover, significant and positive correlations between maximal inspiratory pressure (MIP and the inspiratory-expiratory difference (ΔIE (r = 0.60, p<0.01 were found. CONCLUSION: Patients with chronic obstructive pulmonary disease presented impaired sympathetic-vagal balance at rest. In addition, cardiac autonomic control of heart rate was associated with inspiratory muscle weakness in chronic obstructive pulmonary disease. Based on this evidence, future research applications of respiratory muscle training may bring to light a potentially valuable target for rehabilitation.

    An enzyme-linked immunoabsorbent assay (ELISA) was used to evaluate the levels of antibodies to Mycoplasma ovipneumoniae and M. arginini in lambs with chronic respiratory disease. Sera were obtained from lambs in several flocks at various stages of the clinical disease and tested with sodium dodecyl sulfate (SDS)-treated M. ovipneumoniae and M. arginini whole cells and a crude capsular extract of M. ovipneumoniae as the antigens. There were low levels of antibody to M. ovipneumoniae in flocks sampled at the early stages of infection, whereas increased levels of antibody were present in lambs from flocks that had apparently recovered from the clinical disease. Slowly rising titers of circulating antibodies to M. ovipneumoniae were confirmed by sequential bleeding of lambs during the course of the clinical disease. However, antibody levels of M. arginini were more likely to increase earlier in the disease process. There was significant cross-reactivity between the 2 SDS-treated antigens in both the ELISA test and western immunoblotting. In contrast, the crude capsular extract was specific for detecting antibodies to M. ovipneumoniae.

    Peripheral muscle dysfunction associated with chronic diseases is undeniably a growing problem as one of its main causes, chronic obstructive pulmonary disease (COPD), progresses. Among others, muscle atrophy is one component building the concept of muscle dysfunction. Muscle atrophy has a significant impact on patient clinical status, independent of the impairment in lung function. A lot of effort has been devoted lately to increasing our understanding of the relationship between COPD and the initiation and the development of muscle atrophy. A growing body of evidence is showing that the ubiquitin-proteasome system, an ATP-dependent proteolytic pathway, is playing a crucial role in the cascade leading to degradation of contractile proteins, thus promoting the development of muscle atrophy. Interestingly, this system is also involved in essential cellular processes such as response to hypoxemia and muscle tissue regeneration. In this review, existing evidence linking the activity of the ubiquitin-proteasome system and the cellular events taking place in respiratory and peripheral muscles of patients with COPD are reported. Based on this information, the reader should be able to understand the essential role of this pathway in the context of muscle homeostasis and to picture the coming research in this area.

    Background: Chronic respiratory disease (CRD) causes substantial morbidity and mortality. Although the global CRD epidemic collides with the tuberculosis (TB) epidemic in many low- and middle-income country settings, the risk of TB-associated CRD is not well described in countries with a high burden of TB. Methods: We recruited 136 patients with a history of sputum smear-positive pulmonary TB (PTB) from the TB clinic at Omdurman Teaching Hospital in Khartoum, Sudan, and 136 age- and sex-matched community controls, between 28 July 2013 and 30 December 2013. Data were collected using standardised questionnaires and spirometry was performed before and after bronchodilator. Results: The mean age of the subjects with previous PTB and controls was respectively 44.0 years (SD 8.5) and 44.5 years (SD 8.6), with 27.2% females in both groups. Chronic respiratory symptoms such as chronic cough (OR 6.67, 95%CI 2.98–14.90, P grupo de los casos fue 44,0 (desviación estándar 8,5 años) y en el grupo de testigos fue 44,5 años (8,6 años); la proporción de mujeres en ambos grupos fue 27,2%. Se observó una fuerte asociación entre la presencia de síntomas respiratorios crónicos como la tos (OR 6,67; IC95% 2,98–14,90; P < 0,001) y la presencia de obstrucción crónica al flujo en las vías respiratorias (OR 12,39; IC95% 1,56–98,40; P = 0,02) en las personas con antecedente de TBP, una vez corregidos los posibles factores de confusión. Conclusión: La presencia de rasgos clínicos de EPC exhibe una fuerte correlación con el antecedente de TBP. Es preciso considerar la posibilidad de aplicar un enfoque integrado con el fin de mejorar la atención de ambas enfermedades tan frecuentes. PMID:27695684

    Despite the classic role of Vitamin D in skeletal health, new aspects of Vitamin D have been discovered in tissues and organs other than bones. Epidemiological and observational studies demonstrate a link between Vitamin D deficiency and risk of developing respiratory diseases including asthma, chronic obstructive pulmonary disease (COPD), and tuberculosis (TB). To review the literature, we searched the terms "Vitamin D" (using the set operator) and "asthma," "COPD" and "TB" in electronic databases, including PubMed/MEDLINE, Scopus, and Google Scholar until July 2015. Non-English articles or articles with unavailable full text were excluded. Both in vivo and in vitro studies were included. All the reviewed articles state that Vitamin D deficiency is very common among patients with respiratory diseases. The present data regarding Vitamin D and asthma is still controversial, but data about COPD and TB are more encouraging. The relevant studies have been conducted in different populations therefore it is not particularly possible to compare the data due to genetic variations. In order to point out a role for Vitamin D, large clinical trials with Vitamin D deficient subjects and sufficient Vitamin D supplementation are needed.

    Full Text Available Abstract Background Despite optimal pharmacological therapy and pulmonary rehabilitation, patients with COPD continue to be breathless. There is a need to develop additional strategies to alleviate symptoms. Learning to sing requires control of breathing and posture and might have benefits that translate into daily life. Methods To test this hypothesis we performed a randomised controlled trial, comparing a six week course of twice weekly singing classes to usual care, in 28 COPD patients. The experience of singing was assessed in a qualitative fashion, through interviews with a psychologist. In addition, we surveyed patients with chronic respiratory conditions who participated in a series of open singing workshops. Results In the RCT, the physical component score of the SF36 improved in the singers (n = 15 compared to the controls (n = 13; +7.5(14.6 vs. -3.8(8.4 p = 0.02. Singers also had a significant fall in HAD anxiety score; -1.1(2.7 vs. +0.8(1.7 p = 0.03. Singing did not improve single breath counting, breath hold time or shuttle walk distance. In the qualitative element, 8 patients from the singing group were interviewed. Positive effects on physical sensation, general well-being, community/social support and achievement/efficacy emerged as common themes. 150 participants in open workshops completed a questionnaire. 96% rated the workshops as "very enjoyable" and 98% thought the workshop had taught them something about breathing in a different way. 81% of attendees felt a "marked physical difference" after the workshop. Conclusion Singing classes can improve quality of life measures and anxiety and are viewed as a very positive experience by patients with respiratory disease; no adverse consequences of participation were observed.

However, the effects of obesity on the respiratory system are often underappreciated. In this review, we will discuss the mechanical effects of obesity on lung physiology and the function of adipose tissue as an endocrine organ producing systemic inflammation and effecting central respiratory control. Obesity plays a key role in the development of obstructive sleep apnea and obesity hypoventilation syndrome. Asthma is more common and often harder to treat in the obese population, and in this study, we review the effects of obesity on airway inflammation and respiratory mechanics. We also discuss the compounding effects of obesity on chronic obstructive pulmonary disease (COPD and the paradoxical interaction of body mass index and COPD severity. Many practical challenges exist in caring for obese patients, and we highlight the complications faced by patients undergoing surgical procedures, especially given the increased use of bariatric surgery. Ultimately, a greater understanding of the effects of obesity on the respiratory disease and the provision of adequate health care resources is vital in order to care for this increasingly important patient population.Keywords: obesity, lung function, obstructive sleep apnea, obesity hypoventilation syndrome, anesthesia

    Objective:To evaluate the applicable value of respiratory impedance for the stage 0 of chronic obstructive pulmonary disease (COPD). Methods:Respiratory impedance was measured by impulse oscillometry (IOS) in 41 cases at stage 0 of COPD (NHLBI/WHO, 2001 Standard) and their conventional pulmonary function values were compared with 42 healthy subjects. Both groups had no significant deviation in age, stature and avoirdupois, etc. Master-Screen pulmonary function test system (Jaeger Co, Germany) were used to determine IOS parameters including viscous resistance of 5Hz, 20 Hz and 35Hz (R5, R20, R35), reactance of 5Hz, 35 Hz (X5, X35 ), resonant frequency (Fres) ,total respiratory impedance (Zrs) and routine pulmonary function values including forced expiratory volume in one second to predicted value (FEV1%), forced expiratory volume in one second to forced vital capacity ratio( FEV1/FVC%), maximal mid-expiratory flow (MMEF%),V25% and V50%. Results:Both groups had no significant deviation in FEV1%, FEV1/FVC% and X35 (P>0.05). It was increased significantly in viscous resistance of 5Hz, 20 Hz and 35Hz (R5, R20, R35) in COPD group than that in healthy group (P<0.01). So were Fres and Zrs (P<0.01). MMEF%,V25%,V50% and reactance of 5Hz (X5) in COPD group were marked lower than that in healthy group (P<0.01). The sensitivity of MMEF%, V25%,V50% was higher than others, but its specificity was lower. In parameters of IOS, Fres was the most sensitive index for diagnosis of the small airway function and its specificity was higher than that of MMEF%, V25%,V50%. Conclusion:In the risk case at the stage 0 of COPD, MMEF%, V25% and V50% could be decreased, but Fres, R5,R5-20 could be increased in spite of FEV1% and FEV1/FVC% in normal range.

    Full Text Available Abstract Background Relatively few studies have examined survival by pharmacotherapy level and the effects of patient characteristics on mortality by pharmacotherapy level in older chronic respiratory disease (CRD patients. This study aimed to investigate these issues in older (≥ 65 CRD patients in Western Australia. Methods We identified 108,312 patients ≥ 65 years with CRD during 1992-2006 using linked medical, pharmaceutical, hospital and mortality databases held by the Commonwealth and State governments. Pharmacotherapy classification levels were designed by a clinical consensus panel. Cox regression was used to investigate the study aim. Results Patients using only short acting bronchodilators experienced similar, but slightly worse survival than patients in the highest pharmacotherapy level group using high dose inhaled corticosteroids (ICS ± long acting bronchodilators (LABs ± oral steroids. Patients using low to medium dose ICS ± LABs experienced relatively better survival. Also, male gender was associated with all-cause mortality in all patients (HR = 1.72, 95% CI 1.65-1.80 and especially in those in the highest pharmacotherapy level group (HR = 1.97, 95%CI = 1.84-2.10. The P-value of interaction between gender and pharmacotherapy level for the effect on all-cause death was significant (0.0003. Conclusions Older patients with CRD not using ICS experienced the worst survival in this study and may benefit from an escalation in therapeutic regime. Males had a higher risk of death than females, which was more pronounced in the highest pharmacotherapy level group. Hence, primary health care should more actively direct disease management to mild-to-moderate disease patients.

    Respiratory diseases in Italy already now represent an emergency (they are the 3(rd) ranking cause of death in the world, and the 2(nd) if Lung cancer is included). In countries similar to our own, they result as the principal cause for a visit to the general practitioner (GP) and the second main cause after injury for recourse to Emergency Care. Their frequency is probably higher than estimated (given that respiratory diseases are currently underdiagnosed). The trend is towards a further increase due to epidemiologic and demographic factors (foremost amongst which are the widespread diffusion of cigarette smoking, the increasing mean age of the general population, immigration, and pollution). Within the more general problem of chronic disease care, chronic respiratory diseases (CRDs) constitute one of the four national priorities in that they represent an important burden for society in terms of mortality, invalidity, and direct healthcare costs. The strategy suggested by the World Health Organization (WHO) is an integrated approach consisting of three goals: inform about health, reduce risk exposure, improve patient care. The three goals are translated into practice in the three areas of prevention (1-primary, 2-secondary, 3-tertiary) as: 1) actions of primary (universal) prevention targeted at the general population with the aim to control the causes of disease, and actions of Predictive Medicine - again addressing the general population but aimed at measuring the individual's risk for disease insurgence; 2) actions of early diagnosis targeted at groups or - more precisely - subgroups identified as at risk; 3) continuous improvement and integration of care and rehabilitation support - destined at the greatest possible number of patients, at all stages of disease severity. In Italy, COPD care is generally still inadequate. Existing guidelines, institutional and non-institutional, are inadequately implemented: the international guidelines are not always adaptable

    Objective: To observe the relationship of deep-slow respiratory pattern and respiratory impedance(RI) in patients with chronic obstructive pulmonary disease (COPD). Methods: RI under normal respiration and during deep-slow respiration was measured one after the other with impulse oscillometry for 8 patients with COPD and for 9 healthy volunteers as control. Results: When respiration was changed from normal pattern to the deep-slow pattern, the tidal volume increased and respiratory frequency significantly decreased in both groups (P<0.01), the total respiratory impedance (Z respir) showed a decreasing trend in COPD group, but with no obvious change in the control group. No change in the resonant frequency (fres) was found in both groups, and the respiratory viscous resistance obviously decreased in the COPD group(R5: P=0.0168; R20: P=0.0498; R5-R20: P=0.0388),though in the control group it was unchanged. Conclusion: IOS detection could reflect the response heterogeneity of different compartments of respiratory system during tidal breathing. During deep-slow respiration, the viscous resistance in both central airway and peripheral airway was decreased in patients with COPD. RI measurement by impulse oscillometry may be a convenient pathophysiological method for studying the application of breathing exercise in patients with COPD.

These variables include peak oxygen uptake (VO2 <85% predicted, anaerobic threshold <40%  VO2max predicted, VO2-work rate slope <8.6 mL/watt, oxygen pulse <80% predicted, and ventilatory equivalents for O2 and CO2 at nadir of >31 and >34, respectively. Some of these six variables may be normal while the others are abnormal in patients with chronic obstructive pulmonary disease (COPD. This may result in confusion when using the interpretation algorithm for diagnostic purposes. We therefore hypothesized that patients found to have abnormal values for all six variables would have worse cardiovascular function than patients with abnormal values for none or some of these variables.Methods: In this cross-sectional comparative study, 58 COPD patients attending a university teaching hospital underwent symptom-limited CPET with multiple lactate measurements. Patients with abnormal values in all six IPO-related variables were assigned to an IPO group while those who did not meet the requirements for the IPO group were assigned to a non-IPO group. Cardiovascular function was measured by two-dimensional echocardiography and Δlactate/ΔVO2, and respiratory dynamics were compared between the two groups.Results: Fourteen IPO and 43 non-IPO patients were entered into the study. Both groups were similar with regard to left ventricular ejection fraction and right ventricular morphology (P>0.05 for both. At peak exercise, both groups reached a similar heart rate level and Δlactate/ΔVO2. The IPO patients had an

Lung functions, maximal inspiratory (MIP and expiratory (MEP mouth pressures, chest expansion at the level of the 4th intercostal space (IC and at the level of the xiphoid process (XP, six-minute walk test, health-related quality of life using the St. George’s Questionnaire (SGRQ and fatigue occurrence using the Multidimensional Assessment of Fatigue scale (MAF were tested at the baseline and after 6 weeks. The rehabilitation programme consisted of exercise training, ventilatory muscle training, respiratory physiotherapy and soft-tissue techniques. RESULTS: Patients with COPD improved significantly (p < .05 in MIP by 17% (10.5 cm H2O, MEP by 18% (16.8 cm H2O, IC by 65% (1.7 cm, XP by 90% (1.9 cm, six-minute walk distance (6MWD by 15% (64.1 m and SGRQ by –28% (–12.3 points. Patients with PS improved significantly (p < .05 in MIP by 25% (20.1 cm H2O, IC by 29% (1.3 cm, XP by 29% (1.3 cm and 6MWD by 6% (31.6 m. The change in lung functions and MAF in both groups; MEP and SGRQ in PS group were insignificant after the 6-week rehabilitation programme. CONCLUSIONS: The 6-week rehabilitation programme produces similar responses in functional health status of patients with either obstructive or restrictive ventilatory disorder. However, patients with restrictive ventilatory disorder in particular should be encouraged to continue in the programme to enhance the health

    In China, where air pollution has become a major threat to public health, public awareness of the detrimental effects of air pollution on respiratory health is increasing-particularly in relation to haze days. Air pollutant emission levels in China remain substantially higher than are those in developed countries. Moreover, industry, traffic, and household biomass combustion have become major sources of air pollutant emissions, with substantial spatial and temporal variations. In this Review, we focus on the major constituents of air pollutants and their impacts on chronic respiratory diseases. We highlight targets for interventions and recommendations for pollution reduction through industrial upgrading, vehicle and fuel renovation, improvements in public transportation, lowering of personal exposure, mitigation of the direct effects of air pollution through healthy city development, intervention at population-based level (systematic health education, intensive and individualised intervention, pre-emptive measures, and rehabilitation), and improvement in air quality. The implementation of a national environmental protection policy has become urgent.

    Chronic suppurative lung disease (CSLD) and bronchiectasis in children and adolescents are important causes of respiratory morbidity and reduced quality of life (QoL), also leading to subsequent premature death during adulthood. Acute respiratory exacerbations in pediatric CSLD and bronchiectasis are important markers of disease control clinically, given that they impact upon QoL and increase health-care-associated costs and can adversely affect future lung functioning. Preventing exacerbations in this population is, therefore, likely to have significant individual, familial, societal, and health-sector benefits. In this review, we focus on therapeutic interventions, such as drugs (antibiotics, mucolytics, hyperosmolar agents, bronchodilators, corticosteroids, non-steroidal anti-inflammatory agents), vaccines and physiotherapy, and care-planning, such as post-hospitalization management and health promotion strategies, including exercise, diet, and reducing exposure to environmental toxicants. The review identified a conspicuous lack of moderate or high-quality evidence for preventing respiratory exacerbations in children and adolescents with CSLD or bronchiectasis. Given the short- and long-term impact of exacerbations upon individuals, their families, and society as a whole, large studies addressing interventions at the primary and tertiary prevention phases are required. This research must include children and adolescents in both developing and developed countries and address long-term health outcomes. PMID:28393062

    Full Text Available Asthma and chronic obstructive pulmonary disease (COPD are highly prevalent chronic diseases in the general population. Both are characterized by similar mechanisms: airway inflammation, airway obstruction, and airway hyperresponsiveness. However, the distinction between the two obstructive diseases is not always clear. Multiple epidemiological studies demonstrate that in elderly people with obstructive airway disease, as many as half or more may have overlapping diagnoses of asthma and COPD. A COPD-Asthma overlap syndrome is defined as an airflow obstruction that is not completely reversible, accompanied by symptoms and signs of increased obstruction reversibility. For the clinical identification of overlap syndrome COPD-Asthma Spanish guidelines proposed six diagnostic criteria. The major criteria include very positive bronchodilator test [increase in forced expiratory volume in one second (FEV1 ≥15% and ≥400 ml], eosinophilia in sputum, and personal history of asthma. The minor criteria include high total IgE, personal history of atopy and positive bronchodilator test (increase in FEV1 ≥12% and ≥200 ml on two or more occasions. The overlap syndrome COPD-Asthma is associated with enhanced response to inhaled corticosteroids due to the predominance of eosinophilic bronchial inflammation.The future clinical studies and multicenter clinical trials should lead to the investigation of disease mechanisms and simultaneous development of the novel treatment.

  6. Respiratory Consequences of Mild-to-Moderate Obesity: Impact on Exercise Performance in Health and in Chronic Obstructive Pulmonary Disease

    Full Text Available In many parts of the world, the prevalence of obesity is increasing at an alarming rate. The association between obesity, multiple comorbidities, and increased mortality is now firmly established in many epidemiological studies. However, the link between obesity and exercise intolerance is less well studied and is the focus of this paper. Although exercise limitation is likely to be multifactorial in obesity, it is widely believed that the respiratory mechanical constraints and the attendant dyspnea are important contributors. In this paper, we examined the evidence that critical ventilatory constraint is a proximate source of exercise limitation in individuals with mild-to-moderate obesity. We first reviewed existing information on exercise performance, including ventilatory and perceptual response patterns, in obese individuals who are otherwise healthy. We then considered the impact of obesity in patients with preexisting respiratory mechanical abnormalities due to chronic obstructive pulmonary disease (COPD, with particular reference to the effect on dyspnea and exercise performance. Our main conclusion, based on the existing and rather sparse literature on the subject, is that abnormalities of dynamic respiratory mechanics are not likely to be the dominant source of dyspnea and exercise intolerance in otherwise healthy individuals or in patients with COPD with mild-to-moderate obesity.

    Action Plan B3 of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) focuses on the integrated care of chronic diseases. Area 5 (Care Pathways) was initiated using chronic respiratory diseases as a model. The chronic respiratory disease action plan includes (1) AIRWAYS integrated care pathways (ICPs), (2) the joint initiative between the Reference site MACVIA-LR (Contre les MAladies Chroniques pour un VIeillissement Actif) and ARIA (Allergic Rhinitis and its Impact on Asthma), (3) Commitments for Action to the European Innovation Partnership on Active and Healthy Ageing and the AIRWAYS ICPs network. It is deployed in collaboration with the World Health Organization Global Alliance against Chronic Respiratory Diseases (GARD). The European Innovation Partnership on Active and Healthy Ageing has proposed a 5-step framework for developing an individual scaling up strategy: (1) what to scale up: (1-a) databases of good practices, (1-b) assessment of viability of the scaling up of good practices, (1-c) classification of good practices for local replication and (2) how to scale up: (2-a) facilitating partnerships for scaling up, (2-b) implementation of key success factors and lessons learnt, including emerging technologies for individualised and predictive medicine. This strategy has already been applied to the chronic respiratory disease action plan of the European Innovation Partnership on Active and Healthy Ageing.

    We present our efforts toward enabling a wearable sensor system that allows for the correlation of individual environmental exposures with physiologic and subsequent adverse health responses. This system will permit a better understanding of the impact of increased ozone levels and other pollutants on chronic asthma conditions. We discuss the inefficiency of existing commercial off-the-shelf components to achieve continuous monitoring and our system-level and nano-enabled efforts toward improving the wearability and power consumption. Our system consists of a wristband, a chest patch, and a handheld spirometer. We describe our preliminary efforts to achieve a submilliwatt system ultimately powered by the energy harvested from thermal radiation and motion of the body with the primary contributions being an ultralow-power ozone sensor, an volatile organic compounds sensor, spirometer, and the integration of these and other sensors in a multimodal sensing platform. The measured environmental parameters include ambient ozone concentration, temperature, and relative humidity. Our array of sensors also assesses heart rate via photoplethysmography and electrocardiography, respiratory rate via photoplethysmography, skin impedance, three-axis acceleration, wheezing via a microphone, and expiratory airflow. The sensors on the wristband, chest patch, and spirometer consume 0.83, 0.96, and 0.01 mW, respectively. The data from each sensor are continually streamed to a peripheral data aggregation device and are subsequently transferred to a dedicated server for cloud storage. Future work includes reducing the power consumption of the system-on-chip including radio to reduce the entirety of each described system in the submilliwatt range.

    The objective of this study was to examine the feasibility of a full-scale investigation of the neurophysiological mechanisms of COPD-induced respiratory neuromuscular control deficits. Characterization of respiratory single- and multi-muscle activation patterns using surface electromyography (sEMG) were assessed along with functional measures at baseline and following 21±2 (mean±SD) sessions of respiratory motor training (RMT) performed during a one-month period in four patients with GOLD stage II or III COPD. Pre-training, the individuals with COPD showed significantly increased (prespiratory muscle activity and disorganized multi-muscle activation patterns in association with lowered spirometrical measures and decreased fast- and slow-twitch fiber activity as compared to healthy controls (N=4). Following RMT, functional and respiratory sEMG activation outcomes during quite breathing and forced expiratory efforts were improved suggesting that functional improvements, induced by task-specific RMT, are evidence respiratory neuromuscular networks re-organization.

    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.

    Stem cells have a multitude of clinical implications in the lung. This article is a critical review that includes clinical and experimental studies of MedLine and SciElo database in the last 10 years, where we highlight the effects of stem cell therapy in acute respiratory distress syndrome or more chronic disorders such as lung fibrosis and emphysema. Although, many studies have shown the beneficial effects of stem cells in lung development, repair and remodeling; some important questions need to be answered to better understand the mechanisms that control cell division and differentiation, therefore enabling the use of cell therapy in human respiratory diseases.

    Autologous serum skin test (ASST) is mostly used in chronic spontaneous urticaria (CSU) to show autoreactivity. Interleukin-18 (IL-18) has also been shown to be involved in autoimmune conditions. To investigate the role of autoreactivity assessed by ASST in CSU and respiratory diseases and to investigate whether this autoreactive state is related to IL-18 level or other clinical covariates. Fifty-five patients with CSU (mean age: 40.3 ± 12.3 years), 70 patients with persistent asthma (mean age: 43.7 ± 9.6 years), 21 patients with seasonal allergic rhinitis (SAR) (mean age: 35.5 ± 11.8 years) and 20 normal controls (mean age: 37.7 ± 9.8) were included. All subjects underwent a laboratory examination and skin prick test. ASST was performed and serum IL-18 levels were measured in all subjects. Positive response to ASST and serum IL-18 levels were higher in CSU patients than those with respiratory diseases (asthma and SAR) (P = 0.034 and 0.002, respectively) and normal controls (P = 0.004 and 0.031, respectively). Considering all patients, IL-18 levels were higher in patients with positive ASST (301.8 ± 194.4 vs. 241.8 ± 206.3 pg/ml, P = 0.036) than ASST negative patients. ASST response was associated with disease severity in CSU (P = 0.037) and asthma patients (P = 0.001). Multivariate analysis showed that positive response to ASST was significantly associated with diagnosis of CSU (OR: 3.13, 95% CI: 1.25-7.87) and female gender (OR: 3.98, 95% CI: 1.19-13.38). ASST response could be related with activity of the disease. A positive ASST response found in respiratory diseases patients suggests that it may occur as a result of some inflammatory events during the diseases' process.

    Full Text Available Chronic lower respiratory diseases (CLRDs are a major cause of morbidity and mortality worldwide. The objectives of this study were to estimate the trends in CLRD mortality in Italy, and the specific contributions of age, time period and birth cohort in driving these trends. Population and cause-of-death data in Italy between 1979 and 2010 were collected from the World Health Organization website. Age-specific mortality rates for CLRDs, and effects for age, time period and birth cohort on mortality trends were estimated using age–period–cohort models. Chronic obstructive pulmonary disease (COPD and chronic bronchitis represent nearly 98% of the deaths from CLRDs. Despite the overall number of deaths have been stable (in men or increasing (in women, the age-standardised rates have been steadily decreasing from 1979 to 2010, passing from 104.3 to 55.4 per 100 000 person-years in men and from 32.2 to 19.6 per 100 000 person-years in women. The average relative annual decrease was −3.6% in men and −2.7% in women. Since the end of the 1990s, the decreasing trend of CLRD mortality has started to level off, in particular in women. The decrease in CLRD mortality rates has been more accentuated in more recent cohorts and in younger age groups. Both birth cohort and time period significantly affected the CLRD mortality rates, suggesting that changes in the spread of risk factors (smoking habits, early-life and occupational exposures across different birth cohorts, as well as in advanced in healthcare and medical practice, may have played a major role in secular changes in COPD mortality rates in Italy.

    Full Text Available Background and Objective: Acute exacerbation of chronic obstructive pulmonary disease (COPD leads to increased morbidity, mortality and requirement of invasive mechanical ventilation (MV. The aim of this study was to identify predictors of need of MV in these patients. Materials and Methods: Clinical symptomatology, demographic profile, biochemical parameters including renal functions, liver functions and acid base parameters, and acute physiology and chronic health evaluation II (APACHE II score at the time of admission were recorded in 100 patients of COPD exacerbation. Various parameters were compared between patients in whom MV was required with those managed with medical therapy. Results: MV was required in 73% of the patients. Parameters found to be independent predictors of need of MV were: Admission APACHE-II score ≥ 11.5 {adjusted odds ratio (OR [95% confidence interval (CI]: 1.42 [1.08-1.86]; P = 0.012}, first day pH ≤ 7.28 (adjusted OR [95% CI]: 1.09 [1.02-1.15]; P = 0.008, first day PaCO 2 ≥ 68.6 mmHg (adjusted OR [95% CI]: 1.09 [1.02-1.15]; P = 0.004 and worse premorbid functional status (adjusted OR [95% CI]: 17.01 [1.95-148.68]; P = 0.01. Conclusions: Underlying disease severity as assessed by premorbid functional status and APACHE-II score, and the acuity of respiratory system decompensation as assessed by the admitting arterial pH and PaCO 2 , are independent predictors of need of MV in patients with exacerbation of COPD.

    This study aimed to investigate serotype distribution and antimicrobial resistance of Streptococcus pneumoniae isolates obtained from children with chronic respiratory diseases admitted to hospital with a diagnosis of acute exacerbations between 2008-2010 at Marmara University Hospital, Istanbul, Turkey. Sixty one S.pneumoniae strains isolated from the respiratory samples of patients were studied for erythromycin, clindamycin, tetracyline, trimethoprim-sulphametoxazole (TMP-SMX), vancomycin, levofloxacin susceptibilities by disk diffusion method; MIC values of penicillin and ceftriaxone were determined by E-test (AB Biodisk, Sweden). Results were evaluated according to the CLSI standards. The erythromycin-clindamycin double disc method was applied for the detection of macrolide resistance phenotypes. The presence of macrolide resistance genes, ermB, mef(A)/(E), ermTR were determined by PCR using specific primers for each gene. The serotypes were determined by multiplex PCR using specific primers for 40 different serotypes. According to CLSI criteria, penicillin resistance in S.pneumoniae isolates were found to be 8.2% (5/61) and intermediate resistance rate was 54% (33/61) for oral penicillin. Penicillin resistance were found to be only 1.6% (1/61) for parenteral penicillin. Resistance rates of erythromycin, clindamycin, tetracyline, TMP-SMX were detected as 55.8%, 46%, 47.5% and 67.2%; respectively. No resistance was detected to vancomycin and levofloxacin. Constitutive macrolide-lincosamide-streptogramin B (cMLSB) phenotype and M phenotype were observed in 82.4% (n= 28) and 17.6% (n= 6) of the macrolide resistant isolates, respectively. Inducible macrolide-lincosamide-streptogramin B (iMLSB) phenotype was not detected. The macrolid resistance genotypes, ermB, mef(A)/(E), were positive 50% and 14.7%; respectively. Both ermB and mef(A)/(E) genes were detected 35.3% of the macrolid resistant isolates. None of the isolates were positive for ermTR gene. The most

    A debate at the European Union Parliament was held on 13 November 2012 on the Impact of early diagnosis and control of chronic respiratory diseases on Active and Healthy Ageing (AHA). The debate was held under the auspices of the Cyprus Presidency of the European Union (2012) and represents a follow-up of the priorities of the Polish Presidency of the European Union (2011). It highlighted the importance of early life events on the occurrence of chronic respiratory diseases later in life and their impact on active and healthy ageing. Epidemiologic evidence was followed by actions that should be taken to prevent and manage chronic respiratory diseases in children. The debate ended by practical, feasible and achievable projects, demonstrating the strength of the political action in the field. Three projects will be initiated from this debate: The first will be a meeting sponsored by the Région Languedoc-Roussillon on the developmental origins of chronic diseases and ageing: from research to policies and value creation. The second project is being led by the WHO Collaborating Centre for Asthma and Rhinitis: Prevention of Asthma, Prevention of Allergy (PAPA). The third project is the GA(2)LEN sentinel network.

    Previous occupational asbestos exposure (more rarely environmental or domestic exposure) may induce various pleural and/or pulmonary, benign or malignant diseases, sometimes with a very long latency for malignant mesothelioma (MM). Asbestos has been widely extracted and used in Western countries and in emerging or developing countries, resulting in a peak of MM incidence in France around 2020 and likely in a world pandemic of asbestos-induced diseases. These patients have mostly benign respiratory diseases (pleural plugs) but may also be diagnosed with lung cancer or malignant pleural mesothelioma, and have a global poor outcome. New therapeutic tools (targeted therapies, immunotherapy…) with first promising results are developed. However, it is crucial to obtain a full ban of asbestos use worldwide, and to do a regular follow-up of asbestos-exposed subjects, mostly if they are already diagnosed with benign respiratory diseases. Finally, new cancers (larynx and ovary) were recently added to the list of asbestos-induced tumors.

    Full Text Available Abstract Rationale We had shown that COPD women expressed more dyspnea than men for the same degree of airway obstruction. Objectives Evaluate gender differences in respiratory factors associated with dyspnea in COPD patients. Methods In a FEV1 % matched population of 100 men and women with COPD we measured: age, MMRC, FEV1, FVC, TLC, IC/TLC, PaO2, PaCO2, DLCO, Pimax, P0.1, Ti/Ttot, BMI, ffmi, 6MWD and VAS scale before and after the test, the Charlson score and the SGRQ. We estimated the association between these parameters and MMRC scores. Multivariate analysis determined the independent strength of those associations. Results MMRC correlated with: BMI (men:-0.29, p = 0.04; women:-0.28, p = 0.05, ffmi (men:-0.39, p = 0.01, FEV1 % (men:-0.64, p 2 (men:-0.59, p 2 (men:0.27, p = 0.05, DLCO (men:-0.54, p 0.1/Pimax (men:0.46, p = 0.002; women:0.47, p = 0.005, dyspnea measured with the Visual Analog Scale before (men:0.37, p = 0.04; women:0.52, p = 0.004 and after 6MWD (men:0.52, p = 0.002; women:0.48, p = 0.004 and SGRQ total (men:0.50, p 0.1/Pimax in women (r2 = 0.30 and BMI, DLCO, PaO2 and P0.1/Pimax in men (r2 = 0.81 were the strongest predictors of MMRC scores. Conclusion In mild to severe COPD patients attending a pulmonary clinic, P0.1/Pimax was the unique predictor of MMRC scores only in women. Respiratory factors explain most of the variations of MMRC scores in men but not in women. Factors other than the respiratory ones should be included in the evaluation of dyspnea in women with COPD.

    Full Text Available Objectives. To investigate the effect of the cause of acute respiratory failure and the role of comorbidities both acute and chronic on the outcome of COPD patients admitted to Respiratory Intensive Care Unit (RICU with acute respiratory failure and treated with NIV. Design. Observational prospective study. Patients and Methods. 176 COPD patients consecutively admitted to our RICU over a period of 3 years and treated with NIV were evaluated. In all patients demographic, clinical, and functional parameters were recorded including the cause of acute respiratory failure, SAPS II score, Charlson comorbidity index, and further comorbidities not listed in the Charlson index. NIV success was defined as clinical improvement leading to discharge to regular ward, while exitus or need for endotracheal intubation was considered failure. Results. NIV outcome was successful in 134 patients while 42 underwent failure. Univariate analysis showed significantly higher SAP II score, Charlson index, prevalence of pneumonia, and lower serum albumin level in the failure group. Multivariate analysis confirmed a significant predictive value for pneumonia and albumin. Conclusions. The most important determinants of NIV outcome in COPD patients are the presence of pneumonia and the level of serum albumin as an indicator of the patient nutritional status.

    Respiratory and cardiac diseases are common in older horses. Advancing age is a specific risk factor for cardiac murmurs and these are more likely in males and small horses. Airway inflammation is the most common respiratory diagnosis. Recurrent airway obstruction can lead to irreversible structural change and bronchiectasis; with chronic hypoxia, right heart dysfunction and failure can develop. Valvular heart disease most often affects the aortic and/or the mitral valve. Management of comorbidity is an essential element of the therapeutic approach to cardiac and respiratory disease in older equids.

Mixed virus-viral associations were shown in 21–25% of cases. Respiratory syncytial infections were diagnosed with the highest frequency (50% in patients with BA. Influenza A(H1N1pdm09 and adenoviral infections dominated in persons with ChBO in 50 and 42% of cases, respectively. Response of virus-specific IgG in patients with BA and ChBO indicates the acute course of influenza A(H1N1pdm09 (63% of seroconversions. There were no reactions of IgG which is specific to respiratory syncytial virus in 75% of cases and to adenovirus in 83% of cases, that is the risk factor for occurrence of latent/persistent infection. Presence of structural components of respiratory syncytial virus in the upper respiratory tract had been revealed in three patients with asthma within at least 21–28 days. Respiratory syncytial viral infections and pandemic influenza A(H1N1 pdm09 in patients with BA and ChBO are characterized by the presence of an allergic component, which is indicated by the high levels of virus-specific IgE in blood. An adenoviral infection, in contrast, has no such peculiarity.

    Chronic respiratory failure is a complex entity of varied etiology and physio-pathological mechanisms. It is mainly characterised by the respiratory system's difficulty in ensuring correct aeration at rest, resulting initially in insufficient oxygenation of arterial blood. Treatment is adapted to each etiology and aims to compensate for respiratory failure and to ensure the oxygenation of the organism.

    Full Text Available Latest trends in understanding of respiratory diseases in human beings can be derived from thorough clinical studies of these diseases occurring in man, but conducting such studies in man is difficult in terms of experimental manipulation. In the last 2 decades, various types of experimental respiratory disease models has been developed and utilized by investigators, which have contributed a lot to the understanding of respiratory diseases in man, but only little investigation has been done on the naturally occurring pulmonary diseases of animals as potential models which could have added to our knowledge. There are certain selected examples of spontaneous pulmonary disease in animals that may serve as exploitable models for human chronic bronchitis, bronchiectasis, emphysema, interstitial lung disease, hypersensitivity pneumonitis, hyaline membrane disease, and bronchial asthma.

However, its therapeutic effect remains undefined due to the unclear nature of diaphragmatic mobilization during IMT. Diaphragmatic mobilization, represented by transdiaphragmatic pressure (Pdi, and neural respiratory drive, expressed as the corrected root mean square (RMS of the diaphragmatic electromyogram (EMGdi, both provide vital information to select the proper IMT device and loads in COPD, therefore contributing to the curative effect of IMT. Pdi and RMS of EMGdi (RMSdi% were measured and compared during inspiratory resistive training and threshold load training in stable patients with COPD.Patients and methods: Pdi and neural respiratory drive were measured continuously during inspiratory resistive training and threshold load training in 12 stable patients with COPD (forced expiratory volume in 1 s ± SD was 26.1%±10.2% predicted.Results: Pdi was significantly higher during high-intensity threshold load training (91.46±17.24 cmH2O than during inspiratory resistive training (27.24±6.13 cmH2O in stable patients with COPD, with P<0.01 for each. Significant difference was also found in RMSdi% between high-intensity threshold load training and inspiratory resistive training (69.98%±16.78% vs 17.26%±14.65%, P<0.01.Conclusion: We concluded that threshold load training shows greater mobilization of Pdi and neural respiratory drive than inspiratory resistive training in stable patients with COPD.

    Treatment of periodontal diseases has been associated with benefit outcomes for patients with chronic obstructive pulmonary disease (COPD). However, no population-based cohort study has been conducted. We evaluated this relationship by retrospective cohort study using a large population data.Using the National Health Insurance claims data of Taiwan, we identified 5562 COPD patients with periodontal diseases who had received periodontal treatment as the treatment group. The comparison group was selected at a 1:1 ratio matched by the propensity score estimated with age, sex, date of COPD diagnosis and periodontal treatment, and comorbidities. Both groups were followed up for 5 years to compare risks of acute exacerbation, pneumonia, and acute respiratory failure.The incidence rates of adverse respiratory events were significantly lower in the treatment group than in the comparison group: 3.79 versus 4.21 per 100 person-years for emergency room visits, 2.75 versus 3.65 per 100 person-years for hospitalizations, and 0.66 versus 0.75 per 100 person-years for intensive care unit admissions. The treatment group also had a 37% reduced risk of deaths (1.81 vs 2.87 per 100 person-years), with an adjusted hazard ratio of 0.57 (95% confidence interval 0.52-0.62).Periodontal treatment for COPD patients could reduce the risk of adverse respiratory events and mortality. The adequate periodontal health care is important for COPD patients with periodontal diseases.

    Insomnia is prevalent in patients with chronic obstructive pulmonary disease (COPD).We conducted a population-based case-control study to evaluate the effects of hypnotics on the risk of adverse respiratory events in patients with COPD.The case-control study was investigated using data retrieved from the Taiwan National Health Insurance Research Database. Patients with newly diagnosed adverse respiratory events (pneumonia, COPD with acute exacerbation, acute respiratory failure, and cardiopulmonary arrest) were included in the case group. Patients with COPD and no history of adverse respiratory events were randomly selected for the control group, which was frequency-matched with the case group according to index date, age (per 10 years), and sex. Patients who had used hypnotics within 1 month meant active users. The odds ratios (ORs) and 95% confidence intervals (CIs) of were calculated using univariable and multivariable logistic regression models.Most of the study participants were male (71.6%), and the mean ages of the participants in the case and control groups were 69.2 (±12.4) and 67.5 (±12.3) years, respectively. After potential confounding factors were adjusting for, the adjusted ORs of adverse respiratory events were 12.0 for active users of benzodiazepines (95% CI, 8.11-17.6) and 10.5 for active users of nonbenzodiazepines (95% CI, 7.68-14.2) compared with the adjusted ORs of those who never used hypnotics.The results of this epidemiological study suggested that hypnotics increased the risk of adverse respiratory events in patients with COPD.

    Full Text Available The global prevalence of physiologically defined chronic obstructive pulmonary disease (COPD in adults aged >40 yr is approximately 9-10 per cent. Recently, the Indian Study on Epidemiology of Asthma, Respiratory Symptoms and Chronic Bronchitis in Adults had shown that the overall prevalence of chronic bronchitis in adults >35 yr is 3.49 per cent. The development of COPD is multifactorial and the risk factors of COPD include genetic and environmental factors. Pathological changes in COPD are observed in central airways, small airways and alveolar space. The proposed pathogenesis of COPD includes proteinase-antiproteinase hypothesis, immunological mechanisms, oxidant-antioxidant balance, systemic inflammation, apoptosis and ineffective repair. Airflow limitation in COPD is defined as a postbronchodilator FEV1 (forced expiratory volume in 1 sec to FVC (forced vital capacity ratio <0.70. COPD is characterized by an accelerated decline in FEV1. Co morbidities associated with COPD are cardiovascular disorders (coronary artery disease and chronic heart failure, hypertension, metabolic diseases (diabetes mellitus, metabolic syndrome and obesity, bone disease (osteoporosis and osteopenia, stroke, lung cancer, cachexia, skeletal muscle weakness, anaemia, depression and cognitive decline. The assessment of COPD is required to determine the severity of the disease, its impact on the health status and the risk of future events (e.g., exacerbations, hospital admissions or death and this is essential to guide therapy. COPD is treated with inhaled bronchodilators, inhaled corticosteroids, oral theophylline and oral phosphodiesterase-4 inhibitor. Non pharmacological treatment of COPD includes smoking cessation, pulmonary rehabilitation and nutritional support. Lung volume reduction surgery and lung transplantation are advised in selected severe patients. Global strategy for the diagnosis, management and prevention of Chronic Obstructive Pulmonary Disease

    Melatonin is an indoleamine with potent multifunctional biological and pharmacological effects, both receptor dependent and receptor-independent effects, including antioxidant, anticancer, antitumor, anti-inflammatory, anti-aging, anti-diabetic, antiviral, neuroprotective activities. Melatonin mitigates tissue injury via modification of abnormalities in redox status and other biochemical markers. At the molecular level, the biological and pharmacological activities of melatonin are attributed to the inhibition of nuclear factor-κappa beta (NF-κβ), c-Fos over expression and down-regulation of matrix metalloproteinases-3 (MMP-3), which are regulators of pro-inflammatory and pro-fibrotic cytokines. There are numerous scientific reports on the therapeutic potential of melatonin in treatment of asthma, respiratory diseases for infections, chronic obstructive pulmonary disease, lung cancer, pleural cavity diseases, as well as vascular pulmonary disease. In the present communication, we systematically review the therapeutic potential of melatonin in the treatment of respiratory diseases along with its molecular mechanism of actions.

    Background Early withdraw from invasive mechanical ventilation (MV) followed by noninvasive MV is a new strategy for changing modes of treatment. This study was conducted to estimate the feasibility and the efficacy of early extubation and sequential noninvasive MV commenced at beginning of pulmonary infection control window in patients with exacerbated hypercapnic respiratory failure caused by chronic obstructive pulmonary diseases (COPD). Methods A prospective, randomized controlled study was conducted in eleven teaching hospitals' respiratory or medical intensive care units in China. Ninety intubated COPD patients with severe hypercapnic respiratory failure triggered by pulmonary infection (pneumonia or purulent bronchitis) were involved in the study. When the pulmonary infection had been controlled by antibiotics and comprehensive therapy, the "pulmonary infection control window (PIC window)" has been reached. Each case was randomly assigned to study group (extubation and noninvasive MV via facial mask immediately) or control group (invasive MV was received continuously after PIC window by using conventional weaning technique).Results Study group (n=47) and control group (n=43) had similar clinical characteristics initially and at the time of PIC window. Compared with control group, study group had shorter duration of invasive MV [(6.4±4.4) days vs (11.3±6.2) days, P=0.000], lower rate of ventilator associated pneumonia (VAP) (3/47 vs 12/43, P=0.014), fewer days in ICU [(12±8) days vs (16±11) days, P=0.047] and lower hospital mortality (1/47 vs 7/43, P=0.025).Conclusions In COPD patients requiring intubation and invasive MV for hypercapnic respiratory failure, which is exacerbated by pulmonary infection, early extubation followed by noninvasive MV initiated at the start of PIC window may decrease significantly the duration of invasive MV, the risk of VAP and hospital mortality.

    Patients with chronic obstructive pulmonary disease (COPD) usually complain of symptoms such as cough, sputum, wheezing, and dyspnea. Little is known about clinical symptoms in individuals with restrictive ventilatory impairment. The aim of this study was to compare the prevalence and type of respiratory symptoms in patients with COPD to those reported by individuals with restrictive ventilatory impairment in the Proyecto Latinoamericano de Investigacion en Obstruccion Pulmonar study. Between 2002 and 2004, individuals ≥40 years of age from five cities in Latin America performed pre and post-bronchodilator spirometry and had their respiratory symptoms recorded in a standardized questionnaire. Among the 5315 individuals evaluated, 260 (5.1%) had a restrictive spirometric diagnosis (forced vital capacity (FVC) < lower limit of normal (LLN) with forced expiratory volume in the first second to forced vital capacity ratio (FEV1/FVC) ≥ LLN; American Thoracic Society (ATS)/European Respiratory Society (ERS) 2005) and 610 (11.9%) were diagnosed with an obstructive pattern (FEV1/FVC < LLN; ATS/ERS 2005). Patients with mild restriction wheezed more ((30.8%) vs. (17.8%); p < 0.028). No difference was seen in dyspnea, cough, and sputum between the two groups after adjusting for severity stage. The health status scores for the short form 12 questionnaire were similar in restricted and obstructed patients for both physical (48.4 ± 9.4 vs. 48.3 ± 9.8) and mental (50.8 ± 10.6 vs. 50.0 ± 11.5) domains. Overall, respiratory symptoms are not frequently reported by patients with restricted and obstructed patterns as defined by spirometry. Wheezing was more frequent in patients with restricted pattern compared with those with obstructive ventilatory defect. However, the prevalence of cough, sputum production, and dyspnea are not different between the two groups when adjusted by the same severity stage.

    Purpose: To investigate the incorporation of functional lung image-derived low attenuation area (LAA) based on four-dimensional computed tomography (4D-CT) into respiratory-gated intensity-modulated radiotherapy (IMRT) or volumetric modulated arc therapy (VMAT) in treatment planning for lung cancer patients with chronic obstructive pulmonary disease (COPD). Methods and Materials: Eight lung cancer patients with COPD were the subjects of this study. LAA was generated from 4D-CT data sets according to CT values of less than than -860 Hounsfield units (HU) as a threshold. The functional lung image was defined as the area where LAA was excluded from the image of the total lung. Two respiratory-gated radiotherapy plans (70 Gy/35 fractions) were designed and compared in each patient as follows: Plan A was an anatomical IMRT or VMAT plan based on the total lung; Plan F was a functional IMRT or VMAT plan based on the functional lung. Dosimetric parameters (percentage of total lung volume irradiated with {>=}20 Gy [V20], and mean dose of total lung [MLD]) of the two plans were compared. Results: V20 was lower in Plan F than in Plan A (mean 1.5%, p = 0.025 in IMRT, mean 1.6%, p = 0.044 in VMAT) achieved by a reduction in MLD (mean 0.23 Gy, p = 0.083 in IMRT, mean 0.5 Gy, p = 0.042 in VMAT). No differences were noted in target volume coverage and organ-at-risk doses. Conclusions: Functional IGRT planning based on LAA in respiratory-guided IMRT or VMAT appears to be effective in preserving a functional lung in lung cancer patients with COPD.

    Full Text Available Introduction: The majority of Indian hospitals do not provide intensive care unit (ICU care or ward-based noninvasive positive pressure ventilation (NIV. Because no mechanical ventilation or NIV is available in these hospitals, the majority of patients suffering from respiratory failure die. Objective: To perform a cost-effective analysis of two strategies (ward-based NIV with concurrent standard treatment vs standard treatment alone in chronic obstructive pulmonary disease (COPD respiratory failure patients treated in Indian hospitals without ICU care. Materials and Methods: A decision-analytical model was created to compare the cost-effectiveness for the two strategies. Estimates from the literature were used for parameters in the model. Future costs were discounted at 3%. All costs were reported in USD (2012. One-way, two-way, and probabilistic sensitivity analysis were performed. The time horizon was lifetime and perspective was societal. Results: The NIV strategy resulted in 17.7% more survival and was slightly more costly (increased cost of $101 (USD 2012 but resulted in increased quality-adjusted life-years (QALYs (1.67 QALY. The cost-effectiveness (2012 USD/QALY in the standard and NIV groups was $78/QALY ($535.02/6.82 and $75/QALY ($636.33/8.49, respectively. Incremental cost-effectiveness ratio (ICER was only $61 USD/QALY. This was substantially lower than the gross domestic product (GDP per capita for India (1489 USD, suggesting the NIV strategy was very cost effective. Using a 5% discount rate resulted in only minimally different results. Probabilistic analysis suggests that NIV strategy was preferred 100% of the time when willingness to pay was >$250 2012 USD. Conclusion: Ward-based NIV treatment is cost-effective in India, and may increase survival of patients with COPD respiratory failure when ICU is not available.

    Twenty-five volunteers with chronic obstructive pulmonary disease of mild to moderately severe degree underwent 1-h exposures to 0.12 ppm ozone (O/sub 2/) in purified air with intermittent mild exercise. Their responses were assessed in terms of forced expiratory performance, ear oximetry, and reported symptoms. Control studied consisted of similar exposures to purified air alone. Control studies were separated from O/sub 2/ exposures by 1 month, and the order was randomized. All studies took place in a controlled-environment chamber, and were preceded by approximately 1 h of rest in a purified-air environment. No significant disturbances in forced expiratory performance or symptoms attributable to O/sub 2/ exposure were found. A slight but significant tendency to decreased arterial hemoglobin oxygen saturation (SaO/sub 2/) during exercise in O/sub 2/ was observed. The decrement in SaO/sub 2/ with O/sub 2/ relative to clean air (mean 1.3%) was near the limit of resolution of the ear oximeter test and was detected by signal averaging, thus its physiologic or clinical significance is uncertain.

    Respiratory consequences from occupational and environmental disasters are the result of inhalation exposures to chemicals, particulate matter (dusts and fibers) and/or the incomplete products of combustion that are often liberated during disasters such as fires, building collapses, explosions and volcanoes. Unfortunately, experience has shown that environmental controls and effective respiratory protection are often unavailable during the first days to week after a large-scale disaster. The English literature was reviewed using the key words-disaster and any of the following: respiratory disease, pulmonary, asthma, bronchitis, sinusitis, pulmonary fibrosis, or sarcoidosis. Respiratory health consequences after aerosolized exposures to high-concentrations of particulates and chemicals can be grouped into 4 major categories: 1) upper respiratory disease (chronic rhinosinusitis and reactive upper airways dysfunction syndrome), 2) lower respiratory diseases (reactive [lower] airways dysfunction syndrome, irritant-induced asthma, and chronic obstructive airways diseases), 3) parenchymal or interstitial lung diseases (sarcoidosis, pulmonary fibrosis, and bronchiolitis obliterans, and 4) cancers of the lung and pleura. This review describes several respiratory consequences of occupational and environmental disasters and uses the World Trade Center disaster to illustrate in detail the consequences of chronic upper and lower respiratory inflammation.

    Full Text Available Helmy Haja Mydin, Stephen Murphy, Howell Clague, Kishore Sridharan, Ian K TaylorDepartment of Respiratory Medicine, Sunderland Royal Infirmary, Sunderland, United KingdomBackground: In patients with acute hypercapnic respiratory failure (AHRF during exacerbations of COPD, mortality can be high despite noninvasive ventilation (NIV. For some, AHRF is terminal and NIV is inappropriate. However there is no definitive method of identifying patients who are unlikely to survive. The aim of this study was to identify factors associated with inpatient mortality from AHRF with respiratory acidosis due to COPD.Methods: COPD patients presenting with AHRF and who were treated with NIV were studied prospectively. The forced expiratory volume in 1 second (FEV1, World Health Organization performance status (WHO-PS, clinical observations, a composite physiological score (Early Warning Score, routine hematology and biochemistry, and arterial blood gases prior to commencing NIV, were recorded.Results: In total, 65 patients were included for study, 29 males and 36 females, with a mean age of 71 ± 10.5 years. Inpatient mortality in the group was 33.8%. Mortality at 30 days and 12 months after admission were 38.5% and 58.5%, respectively. On univariate analysis, the variables associated with inpatient death were: WHO-PS ≥ 3, long-term oxygen therapy, anemia, diastolic blood pressure < 70 mmHg, Early Warning Score ≥ 3, severe acidosis (pH < 7.20, and serum albumin < 35 g/L. On multivariate analysis, only anemia and WHO-PS ≥ 3 were significant. The presence of both predicted 68% of inpatient deaths, with a specificity of 98%.Conclusion: WHO-PS ≥ 3 and anemia are prognostic factors in AHRF with respiratory acidosis due to COPD. A combination of the two provides a simple method of identifying patients unlikely to benefit from NIV.Keywords: acute exacerbations of COPD, noninvasive ventilation, emphysema, prognostic markers

    Respiratory diseases affect humanity globally, with chronic lung diseases (e.g., asthma, chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis, among others) and lung cancer causing extensive morbidity and mortality. These conditions are highly heterogeneous and require an early diagnosis. However, initial symptoms are nonspecific, and the clinical diagnosis is made late frequently. Over the last few years, personalized medicine has emerged as a medical care approach that uses novel technology aiming to personalize treatments according to the particular patient's medical needs. This review highlights the contributions of proteomics toward the understanding of personalized medicine in respiratory disease and its potential applications in the clinic.

    Background: Application noninvasive ventilation in the patients with exacerbation of chronic obstructive pulmonary disease (COPD) reduced mortality. This case-control study was designed to compare efficiency and outcome of non-invasive (NIV) versus invasive positive pressure ventilation (IPPV) in respiratory failure due to COPD. Methods: The patients were assigned to NIV or IPPV intermittantly.The clinical parameters, including RR (respiratory rate), BP (blood pressure), HR (heart rate) and PH, PaCO2, PaO2 before and 1, 4 and 24 h after treatment were measured. Demographic information such as age, sex, severity of disease based on APACHE score, length of stay and outcome were recorded. Results: Fifty patients were enrolled in the NIV group and 50 patients in IPPV. The mean age was 70.5 in NIV and 63.9 in invasive ventilation group (p>0.05). In IPPV group, the average values of PH: PCO2: and PO2, were 7.22±0.11, 69.64 + 24.25: and 68.86±24.41 .In NIV, the respective values were 7.30±0.07, 83.94±18.95, and 60.60±19.88. In NIV group, after 1, 4 and 24 h treatment, the clinical and ventilation parameters were stable. The mean APACHE score in was IPPV, 26.46±5.45 and in NIV was 12.26±5.54 (p<0.05). The average length of hospital stay in IPPV was 15.90±10 and in NIV 8.12±6.49 days (p<0.05). The total mortality in the NIV was 4 (8%) and in IPPV, 27 patients (54%) (p<0.05). Conclusion: This study indicates that using NIPPV is a useful therapeutic mode of treatment for respiratory failure with acceptable success rate and lower mortality. The application of NIPPV reduces hospital stay, intubation and its consequent complications. PMID:27386061

    Full Text Available The effects of adding L-carnitine to a whole-body and respiratory training program were determined in moderate-to-severe chronic obstructive pulmonary disease (COPD patients. Sixteen COPD patients (66 ± 7 years were randomly assigned to L-carnitine (CG or placebo group (PG that received either L-carnitine or saline solution (2 g/day, orally for 6 weeks (forced expiratory volume on first second was 38 ± 16 and 36 ± 12%, respectively. Both groups participated in three weekly 30-min treadmill and threshold inspiratory muscle training sessions, with 3 sets of 10 loaded inspirations (40% at maximal inspiratory pressure. Nutritional status, exercise tolerance on a treadmill and six-minute walking test, blood lactate, heart rate, blood pressure, and respiratory muscle strength were determined as baseline and on day 42. Maximal capacity in the incremental exercise test was significantly improved in both groups (P < 0.05. Blood lactate, blood pressure, oxygen saturation, and heart rate at identical exercise levels were lower in CG after training (P < 0.05. Inspiratory muscle strength and walking test tolerance were significantly improved in both groups, but the gains of CG were significantly higher than those of PG (40 ± 14 vs 14 ± 5 cmH2O, and 87 ± 30 vs 34 ± 29 m, respectively; P < 0.05. Blood lactate concentration was significantly lower in CG than in PG (1.6 ± 0.7 vs 2.3 ± 0.7 mM, P < 0.05. The present data suggest that carnitine can improve exercise tolerance and inspiratory muscle strength in COPD patients, as well as reduce lactate production.

    Chronic rhinosinusitis is an inflammatory disease of the upper respiratory tract, and has an important impact on the lower respiratory tract diseases. Epidemiological and clinical studies have proved that the upper and lower respiratory tract inflammatory diseases are usually combined. The view of the"united airway disease"is widely accepted by the medical community. The upper and lower respiratory tract are continued in anatomical structure, and have similar morphology and physiological function, so that the inlfammation can be mutually involved. In this paper, the relationship and possible mechanisms between chronic rhinosinusitis and lower respiratory tract diseases are reviewed, which provide theoretical basis for the comprehensive treatment and prevention of upper and lower respiratory tract diseases.%慢性鼻-鼻窦炎作为上呼吸道炎症性疾病,对下呼吸道疾病有重要影响。流行病学和临床研究已证明上、下呼吸道炎性疾病通常合并存在,“联合气道疾病”观点随着研究的深入,逐渐得到医学界的广泛认同。上、下呼吸道各部在解剖结构上延续,组织形态及生理功能上相似,所以炎症发生时可以相互累及。本文就慢性鼻-鼻窦炎与下呼吸道疾病的相关关系及可能机制进行综述,为上、下呼吸道疾病的综合治疗和预防提供理论依据。

    Full Text Available Abstract Background Patients with acute exacerbation of chronic obstructive pulmonary disease (COPD commonly require hospitalization and admission to intensive care unit (ICU. It is useful to identify patients at the time of admission who are likely to have poor outcome. This study was carried out to define the predictors of mortality in patients with acute exacerbation of COPD and to device a scoring system using the baseline physiological variables for prognosticating these patients. Methods Eighty-two patients with acute respiratory failure secondary to COPD admitted to medical ICU over a one-year period were included. Clinical and demographic profile at the time of admission to ICU including APACHE II score and Glasgow coma scale were recorded at the time of admission to ICU. In addition, acid base disorders, renal functions, liver functions and serum albumin, were recorded at the time of presentation. Primary outcome measure was hospital mortality. Results Invasive ventilation was required in 69 patients (84.1%. Fifty-two patients survived to hospital discharge (63.4%. APACHE II score at the time of admission to ICU {odds ratio (95 % CI: 1.32 (1.138–1.532; p Conclusion APACHE II score at admission and SA levels with in 24 hrs after admission are independent predictors of mortality for patients with COPD admitted to ICU. The equation derived from these two parameters is useful for predicting outcome of these patients.

    Background Chronic obstructive pulmonary diseases (COPD) is an emerging population at risk for invasive infection of Aspergillus.Isolation of Aspergillus from lower respiratory tract (LRT) samples is important for the diagnosis of invasive pulmonary aspergillosis (IPA).The purpose of this study was to investigate the value of Aspergillus isolation from LRT samples for the diagnosis and prognosis of IPA in COPD population.Methods Clinical record with Aspergillus spp.isolation in COPD and immunocompromised patients was reviewed in a retrospective study.Patients were categorized and compared according to their severity of illness (admitted to general ward or ICU) and immunological function (COPD or immunocompromised).Results Multivariate statistical analysis showed that,combined with Aspergillus spp.isolation,APACHE Ⅱ scores >18,high cumulative doses of corticosteroids (>350 mg prednisone or equivalent dose) and more than four kinds of broad-spectrum antibiotics received in hospital may be predictors of IPA in COPD (OR=9.076,P=0.001; OR=4.073,P=-0.026; OR=4.448,P=0.021,respectively).The incidence of IPA,overall mortality,mortality of patients with IPA and mortality of patients with Aspergillus spp.colonization were higher in COPD patients in ICU than in general ward,but were similar between COPD and immunocompromised patients.Conclusions Aspergilltus spp.isolation from LRT in COPD may be of similar importance as in immunocompromised patients,and may indicate an increased diagnosis possibility of IPA and worse prognosis when these patients received corticosteroids,antibiotics,and need to admit to ICU.Aspergillus spp.isolation from LRT samples combined with certain risk factors may be useful in differentiating colonization from IPA and evaluating the prognosis of IPA in COPD patients.

    Full Text Available The link between heart disease and infectious pathogens is well known. Despite the high frequency of cardiac pathology in infectious diseases, it is rarely diagnosed because of lack of specific clinical  and  laboratory  symptoms. It is especially  difficult to diagnose in  children. Airborne  infections in the structure of infectious morbidity of children occupy a leading place.The aim of this work was to study the nature of the lesions of the heart  in children suffering from acute infection of the respiratory tract.Materials and  methods: 341 children with acute respiratory infection of moderate severity were surveyed by a method of ECG dispersion mapping. Cardiac  pathology has not previously been determined in these children. Signs of disease of the heart was identified in 76 children (22%. Further study included instrumental (ECG, ECHO-KG,  daily monitoring of ECG, biochemical and  etiological (ELISA, PCR, immunocytochemical research  methods for determining the nature of the damage to the heart and the etiology of the disease.Results. Myocarditis was diagnosed in 2%  of children, a violation of repolarization – in 21%,  heart  rhythm disorders  – in 35%  (AV – blockade in 4%.  Most  often  signs  of heart disease were detected in children with Epstein-Barr virus (32%, streptococcal (28%, cytomegalovirus (25%, herpesvirus type  6 infection (24%. Pathogens from the  group of acute respiratory virus infections were identified in 28%, enterovirus – in  10%,  Haemophilus influenzae – in  10%, Mycoplasma pneumonia – in 10%,  Pneumococcus – in 9%, Chlamydia – in 9%, Parvovirus B19 – in 6%.Conclusion. Sensitive screening test  to  detect cardiac pathology is the method of ECG dispersion mapping. Heart damage in children with respiratory diseases in 60% of cases is associated with  mixed infections.

    In the past few years, a variety of extradigestive disorders,including cardiovascular, skin, rheumatic and liver diseases,have been associated with Helicobacter pylori(H. pylori)infection. The activation of inflammatory mediators by H. pyloriseems to be the pathogenetic mechanism underlying theobserved associations. The present review summarizes thecurrent literature, including our own studies, concerning theassociation between H. pvloriinfection and respiratory diseases.A small number of epidemiological and serologic, case-control studies suggest that H. pyloriinfection may beassociated with the development of chronic bronchitis. Afrequent coexistence of pulmonary tuberculosis and H. pyloriinfection has also been found. Moreover, recent studies haveshown an increasedH. pyloriseroprevalence in patients withbronchiectasis and in those with lung cancer. On the otherhand, bronchial asthma seems not to be related withH. pyloriinfection.All associations between H. pyloriinfection and respiratorydiseases are primarily based on case-control studies,concerning relatively small numbers of patients. Moreover,there is a lack of studies focused on the pathogenetic linkbetween respiratory diseases and H. pylori infection.Therefore, we believe that larger studies should beundertaken to confirm the observed results and to clarifythe underlying pathogenetic mechanisms.

    Objective: To determine prevalence of depression in chronic respiratory disorders in a tertiary rural hospital of Central India. Various studies done in past have shown that prevalence of depression in diabetes and hypertension is around 40%-57%. Few studies have been done to screen depression in chronic respiratory disorders. This study was conducted in a tertiary rural hospital of Central India to find out prevalence of depression in indoor patients suffering from chronic respiratory disorders. Methods: Total 68 patients were evaluated for depression. Patients suffering from chronic respiratory disorders (total duration of illness >3 months) were evaluated using Prime MD Questionnaire. Patients suffering from diabetes, heart diseases, stroke, having past history of psychiatric illness, drug abusers, having lack of social support and suffering from chronic upper respiratory tract infections were excluded from this study. Questionnaire was asked when treatment for acute phase of illness is over. Results: Out of 68 patients evaluated, 36 (53%) were found out to be suffering from depression. Female gender (80%) was more prone to depression, inspite of the fact that all alcoholics were male. 39% of all chronic obstructive pulmonary disease (COPD) patients were suffering from depression in comparison to 65% for pulmonary tuberculosis and 44% for other chronic respiratory illness. 54% of patients suffering from depression are 60 yrs of age, suggesting that age has no relation with depression. No association was seen between alcoholism and depression. Conclusion: Prevalence of depression in patients of chronic respiratory illness is very high, like in cases of diabetes and hypertension. Further community and hospital based studies are needed to find out exact prevalence of depression in chronic respiratory illnesses.

    Abstract Noninvasive positive-pressure ventilation (NPPV) might be superior to conventional mechanical ventilation (CMV) in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPDs). Inefficient clearance of respiratory secretions provokes NPPV failure in patients with hypercapnic encephalopathy (HE). This study compared CMV and NPPV combined with a noninvasive strategy for clearing secretions in HE and AECOPD patients. The present study is a prospective cohort study of AECOPD and HE patients enrolled between October 2013 and August 2015 in a critical care unit of a major university teaching hospital in China. A total of 74 patients received NPPV and 90 patients received CMV. Inclusion criteria included the following: physician-diagnosed AECOPD, spontaneous airway clearance of excessive secretions, arterial blood gas analysis requiring intensive care, moderate-to-severe dyspnea, and a Kelly–Matthay scale score of 3 to 5. Exclusion criteria included the following: preexisting psychiatric/neurological disorders unrelated to HE, upper gastrointestinal bleeding, upper airway obstruction, acute coronary syndromes, preadmission tracheostomy or endotracheal intubation, and urgent endotracheal intubation for cardiovascular, psychomotor agitation, or severe hemodynamic conditions. Intensive care unit participants were managed by NPPV. Participants received standard treatment consisting of controlled oxygen therapy during NPPV-free periods; antibiotics, intravenous doxofylline, corticosteroids (e.g., salbutamol and ambroxol), and subcutaneous low-molecular-weight heparin; and therapy for comorbidities if necessary. Nasogastric tubes were inserted only in participants who developed gastric distension. No pharmacological sedation was administered. The primary and secondary outcome measures included comparative complication rates, durations of ventilation and hospitalization, number of invasive devices/patient, and in-hospital and 1-year mortality

    @@ Chronic Mountain Sickness (CMS) is a multifactorial disease caused by a limited capacity to achieve complete adaptation to life under chronic hypoxic conditions. It is accompanied by excessive erythrocitosis (levels of erythrocytes above the normal value set for each altitude), and in advances cases also by pulmonary hypertension. The hypoxemia, caused by central or peripheral respiratory disorders and/or associated to diverse risk factors, produces the excessive erythrocytosis. The most common symptoms are headaches, dizziness, breathlessness, sleep disturbances, tinnitus, physical and mental fatigue, anorexia, and bone and muscle pain. The most common signs are an intermittent or permanent cyanosis, hyperemia and venous dilatation in hands or feet (Monge-M et al., 1928; Winslow and Monge-C, 1987). Aging, respiratory diseases, sleep, menopause, and overweight has proved to be additional risk factors in the development of CMS (Kryger et al., 1978; León-Velarde et al., 1993; Sime et al., 1975; León-Velarde et al., 1997; León-Velarde et al., 2001; Monge-C et al., 1992; Normand et al., 1992)

    Full Text Available Abstract Background Population-based data on hospital admissions for children aged 0-17 years concerning all respiratory diseases are scarce. This study examined hospital admissions in relation to the preceding consultations in general practice in this age group. Methods Data on children aged 0-17 years with respiratory diseases included in the Second Dutch National Survey of General Practice (DNSGP-2 were linked to all hospital admissions in the Dutch National Medical Registration. Admission rates for respiratory diseases were calculated. Data were analysed using multivariate logistic regression. Results Of all 79,272 children within the DNSGP-2, 1.8% were admitted to hospital for any respiratory diagnosis. The highest admission rates per 1000 children were for chronic disease of tonsils and adenoids (12.9; pneumonia and influenza (0.97; and asthma (0.92. Children aged 0-4 years and boys were admitted more frequently. Of children with asthma, 2.3% were admitted for respiratory diseases. For asthma, admission rates varied by urbanisation level: 0.47/1000 children/year in cities with ≤ 30,000 inhabitants, 1.12 for cities with ≥ 50,000 inhabitants, and 1.73 for the three largest cities (p = 0.002. Multivariate logistic regression showed that within two weeks after a GP consultation, younger age (OR 0.81, 95% CI 0.76-0.88 and more severe respiratory diseases (5.55, 95% CI 2.99-8.11 predicted hospital admission. Conclusions Children in the general population with respiratory diseases (especially asthma had very low hospital admission rates. In urban regions children were more frequently admitted due to respiratory morbidity. For effectiveness studies in a primary care setting, hospital admission rates should not be used as quality end-point.

    Full Text Available Chronic obstructive pulmonary disease, namely, pulmonary emphysema and chronic bronchitis, is a chronic inflammatory response of the airways to noxious particles or gases, with resulting pathological and pathophysiological changes in the lung. The main pathophysiological aspects of the disease are airflow obstruction and hyperinflation. The mechanical properties of the respiratory system and its component parts are studied by determining the corresponding volume-pressure (P-V relationships. The consequences of the inflammatory response on the lung structure and function are depicted on the volume-pressure relationships.

    Respiratory muscle strength is one parameter that is currently proposed to be affected in patients with chronic neck pain. This study was aimed at examining whether patients with chronic neck pain have reduced respiratory strength and with which neck pain problems their respiratory strength is associated. In this controlled cross-sectional study, 45 patients with chronic neck pain and 45 healthy well-matched controls were recruited. Respiratory muscle strength was assessed through maximal mouth pressures. The subjects were additionally assessed for their pain intensity and disability, neck muscle strength, endurance of deep neck flexors, neck range of movement, forward head posture and psychological states. Paired t-tests showed that patients with chronic neck pain have reduced Maximal Inspiratory (MIP) (r = 0.35) and Maximal Expiratory Pressures (MEP) (r = 0.39) (P Neck muscle strength (r > 0.5), kinesiophobia (r neck pain and disability (r Neck muscle strength was the only predictor that remained as significant into the prediction models of MIP and MEP. It can be concluded that patients with chronic neck pain present weakness of their respiratory muscles. This weakness seems to be a result of the impaired global and local muscle system of neck pain patients, and psychological states also appear to have an additional contribution. Clinicians are advised to consider the respiratory system of patients with chronic neck pain during their usual assessment and appropriately address their treatment.

    Full Text Available Recurrent respiratory papillomatosis (RRP, which is caused exclusively by human papilloma virus (HPV, is a rare condition characterized by recurrent growth of benign papillomata in the respiratory tract. The papillomata can occur anywhere in the aerodigestive tract but most frequently in the larynx, affecting both children and adults. The management of this entity remains still challenging since no specific definitive treatment exists. Nevertheless, novel surgical interventions as well as several adjuvant therapies have shown promising results in the long-term palliative management of this debilitating disease. Despite its mostly benign nature, RRP may cause significant morbidity and mortality because of its unpredictable clinical course and especially its tendency, albeit infrequent, for malignant transformation. In this article, we present two patients with RRP; one underwent bronchoscopic laser ablation in combination with inhaled interferon-alpha administration that led to a long-term regression of the disease while the other patient was diagnosed with transformation to squamous cell lung carcinoma with fatal outcome. We include a review of the current literature with special emphasis on RRP management and the potential role of HPV in the development of lung cancer.

    Full Text Available A doença pulmonar obstrutiva crônica é uma condição freqüente e é hoje a quarta principal causa de mortes nos Estados Unidos. A prevalência de perturbação respiratória durante o sono, ou síndrome de superposição, como anteriormente denominada, ainda não foi determinada devido à publicação de relatos conflitantes. Esta condição deve continuar sendo investigada devido aos efeitos adversos causados por transtornos respiratórios relacionados ao sono em pacientes com doença pulmonar de base. Neste relato, discutiremos brevemente os mecanismos envolvidos na origem da perturbação respiratória durante o sono em doença pulmonar obstrutiva crônica e auxiliaremos o leitor a distinguir àqueles pacientes que se beneficiariam de uma avaliação do padrão do sono mais detalhada, com a discussão de tópicos de gerenciamento e opções de tratamento.Chronic obstructive pulmonary disease is a prevalent condition and is currently the forth leading cause of mortality in the US. The prevalence of respiratory disturbance during sleep, or overlap syndrome as it was commonly known in the past, is still undetermined as conflicting reports have been published. Because of the adverse effects of sleep-related respiratory impairment in patients with underlying pulmonary disease, this condition deserves further investigation. In this report, we will briefly discuss the mechanisms involved in generating respiratory disturbance during sleep in Chronic Obstructive Pulmonary Disease and will guide the reader into distinguishing those patients who would benefit from a more detailed sleep evaluation, discussing management issues and treatment options.

    Full Text Available Several respiratory diseases feature increased inflammatory response and catabolic activity, which are associated with glutamine depletion; thus, the benefits of exogenous glutamine administration have been evaluated in clinical trials and models of different respiratory diseases. Recent reviews and meta-analyses have focused on the effects and mechanisms of action of glutamine in a general population of critical care patients or in different models of injury. However, little information is available about the role of glutamine in respiratory diseases. The aim of the present review is to discuss the evidence of glutamine depletion in cystic fibrosis (CF, asthma, chronic obstructive pulmonary disease (COPD, acute respiratory distress syndrome (ARDS, and lung cancer, as well as the results of exogenous glutamine administration in experimental and clinical studies. Exogenous glutamine administration might be beneficial in ARDS, asthma, and during lung cancer treatment, thus representing a potential therapeutic tool in these conditions. Further experimental and large randomized clinical trials focusing on the development and progression of respiratory diseases are necessary to elucidate the effects and possible therapeutic role of glutamine in this setting.

    Inhaled oligonucleotide is an emerging therapeutic modality for various common respiratory diseases, including obstructive airway diseases like asthma and chronic obstructive pulmonary disease (COPD) and restrictive airway diseases like idiopathic pulmonary fibrosis (IPF). The advantage of direct accessibility for oligonucleotide molecules to the lung target sites, bypassing systemic administration, makes this therapeutic approach promising with minimized potential systemic side effects. Asthma, COPD, and IPF are common chronic respiratory diseases, characterized by persistent airway inflammation and dysregulated tissue repair and remodeling, although each individual disease has its unique etiology. Corticosteroids have been widely prescribed for the treatment of asthma, COPD, and IPF. However, the effectiveness of corticosteroids as an anti-inflammatory drug is limited by steroid resistance in severe asthma, the majority of COPD cases, and pulmonary fibrosis. There is an urgent medical need to develop target-specific drugs for the treatment of these respiratory conditions. Oligonucleotide therapies, including antisense oligonucleotide (ASO), small interfering RNA (siRNA), and microRNA (miRNA) are now being evaluated both pre-clinically and clinically as potential therapeutics. The mechanisms of action of ASO and siRNA are highly target mRNA specific, ultimately leading to target protein knockdown. miRNA has both biomarker and therapeutic values, and its knockdown by a miRNA antagonist (antagomir) has a broader but potentially more non-specific biological outcome. This review will compile the current findings of oligonucleotide therapeutic targets, verified in various respiratory disease models and in clinical trials, and evaluate different chemical modification approaches to improve the stability and potency of oligonucleotides for the treatment of respiratory diseases.

    2013-05-01

    Chronic respiratory diseases (CRDs) are a heterogeneous group of diseases that can affect the pediatric population and health authorities throughout the world recommend influenza vaccination because of the significant risk of influenza-related complications. However, despite this recommendation, vaccine coverage is generally unsatisfactory. The aim of this review is to analyze the impact of influenza on children at high risk of respiratory disease, and the immunogenicity, safety and efficacy of influenza vaccination in such children. The results show that there is a significant risk of influenza-related complications in preterm neonates and infants, in whom influenza vaccines are immunogenic and safe (although their efficacy has not been specifically studied). There are conflicting data concerning the effect of influenza infection on asthma morbidity in children, and whether or not influenza vaccination helps to prevent asthma exacerbations. Recent data provide no evidence that influenza is more frequent in patients with cystic fibrosis than in healthy subjects, or that it is responsible for increased lower respiratory tract morbidity. The lack of any clear correlate of protection suggests that future studies should also consider the efficacy of the different influenza vaccines and not only evaluate them in terms of immunogenicity. Furthermore, there is a need for clinical studies to assess the effectiveness of the available vaccines in patients with other rare CRDs and other chronic underlying diseases with possibly severe respiratory involvement. It is also important to determine whether children with recurrent respiratory tract infections should be included in the list of those for whom influenza vaccination is recommended. In the meantime, given the increasing evidence of the burden of influenza on the population as a whole and the benefits associated with vaccination, annual influenza vaccinations should be recommended for all children at high risk of

    Full Text Available Abstract Background Inspiratory occlusion evoked cortical potentials (the respiratory related-evoked potentials, RREPs bear witness of the processing of changes in respiratory mechanics by the brain. Their impairment in children having suffered near-fatal asthma supports the hypothesis that relates asthma severity with the ability of the patients to perceive respiratory changes. It is not known whether or not chronic respiratory defects are associated with an alteration in brain processing of inspiratory loads. The aim of the present study was to compare the presence, the latencies and the amplitudes of the P1, N1, P2, and N2 components of the RREPs in children with chronic lung or neuromuscular disease. Methods RREPs were recorded in patients with stable asthma (n = 21, cystic fibrosis (n = 32, and neuromuscular disease (n = 16 and in healthy controls (n = 11. Results The 4 RREP components were significantly less frequently observed in the 3 groups of patients than in the controls. Within the patient groups, the N1 and the P2 components were significantly less frequently observed in the patients with asthma (16/21 for both components and cystic fibrosis (20/32 and 14/32 than in the patients with neuromuscular disease (15/16 and 16/16. When present, the latencies and amplitudes of the 4 components were similar in the patients and controls. Conclusion Chronic ventilatory defects in children are associated with an impaired cortical processing of afferent respiratory signals.

    The respiratory system is one of the most important body systems particularly from the viewpoint of occupational medicine because it is the major route of occupational exposure. In 2013, there were significant changes in the specific criteria for the recognition of occupational diseases, which were established by the Enforcement Decree of the Industrial Accident Compensation Insurance Act (IACIA). In this article, the authors deal with the former criteria, implications of the revision, and changes in the specific criteria in Korea by focusing on the 2013 amendment to the IACIA. Before the 2013 amendment to the IACIA, occupational respiratory disease was not a category because the previous criteria were based on specific hazardous agents and their health effects. Workers as well as clinicians were not familiar with the agent-based criteria. To improve these criteria, a system-based structure was added. Through these changes, in the current criteria, 33 types of agents and 11 types of respiratory diseases are listed under diseases of the respiratory system. In the current criteria, there are no concrete guidelines for evaluating work-relatedness, such as estimating the exposure level, latent period, and detailed examination methods. The results of further studies can support the formulation of detailed criteria.

Though effective pharmacotherapy options exist, no agent is universally efficacious; therapeutic decisions must account for individual patient preferences. Oral H1-antihistamines, though effective for the common symptoms of allergic rhinitis, have modest decongestant action, as do leukotriene receptor antagonists. Intranasal antihistamines appear to improve congestion better than oral forms. Topical decongestants reduce congestion associated with allergic rhinitis, but local adverse effects make them unsuitable for long-term use. Oral decongestants show some efficacy against congestion in allergic rhinitis and the common cold, and can be combined with oral antihistamines. Intranasal corticosteroids have broad anti-inflammatory activities, are the most potent long-term pharmacologic treatment of congestion associated with allergic rhinitis, and show some congestion relief in rhinosinusitis and nasal polyposis. Immunotherapy and surgery may be used in some cases refractory to pharmacotherapy. Steps in congestion management include (1 diagnosis of the cause(s, (2 patient education and monitoring, (3 avoidance of environmental triggers where possible, (4 pharmacotherapy, and (5 immunotherapy

    This retrospective cohort study aimed to analyze the prescribing practices of general practitioners treating patients with newly diagnosed chronic obstructive pulmonary disease (COPD), and to assess characteristics associated with initial pharmacotherapy. Patients were identified in the General Practice Research Database, a population-based UK electronic medical record (EMR) with data from January 1, 2008 to December 31, 2009. Patient characteristics, prescribed COPD pharmacotherapies (≤12 months before diagnosis and within 3 months following diagnosis), co-morbidities, hospitalizations, and events indicative of a possible COPD exacerbation (≤12 months before diagnosis) were analyzed in 7881 patients with newly diagnosed COPD. Most patients (64.4%) were prescribed COPD pharmacotherapy in the 12 months before diagnosis. Following diagnosis, COPD pharmacotherapy was prescribed within 3 months in 85.0% of patients. Short-acting bronchodilators alone (22.9%) or inhaled corticosteroids + long-acting beta-2 agonists (ICS+LABA, 22.1%) were prescribed most frequently. Compared with other pharmacotherapies, the prevalence of severe airflow limitation was highest in patients prescribed ICS+LABA+long-acting muscarinic antagonists (LAMA). Moderate-to-severe dyspnea was identified most frequently in patients prescribed a LAMA-containing regimen. Patients prescribed an ICS-containing regimen had a higher prevalence of asthma or possible exacerbations recorded in the EMR than those not prescribed ICS. In conclusion, pharmacotherapy prescribed at initial COPD diagnosis varied by disease severity indicators as assessed by airflow limitation, dyspnea, history of asthma, and possible exacerbations. Frequent prescription of COPD pharmacotherapies before the first-recorded COPD diagnosis indicates a delay between obstructive lung disease presentation in primary care practice and assignment of a medical diagnosis.

    Acrylates are compounds used in a variety of industrial fields and their use is increasing. They have many features which make them superior to formerly used chemicals, regarding both their industrial use and their possible health effects. Contact sensitization is, however, one of their well known adverse health effects but they may also cause respiratory symptoms. We report on 18 cases of respiratory disease, mainly asthma, caused by different acrylates, 10 cases caused by cyanoacrylates, four by methacrylates and two cases by other acrylates.

  6. [Legislation on professional respiratory diseases].

    Science.gov (United States)

    Lezaun, M

    2005-01-01

    The legally protected occupational pathology consists of work accidents and occupational diseases. Diseases are considered to be occupational when there is a relationship of demonstrable causality between exposure to a determinate occupational risk and a specific disease. To facilitate recognition, different organisations (International Labour Organisation, European Community) draw up, update and recommend the use of lists that are voluntarily adopted by member states. In the case of the Spanish state, the system of the closed list has been adopted. The current list was published in 1978 and the system of notification and registration currently in use is in need of urgent reform, which has been started. It is frequently difficult to identify the work-related origin of occupational diseases and they are often treated in the public health care system without their relation to work being recognised. Knowledge of some basic aspects of the labour legislation by the health workers and the inclusion of a few questions during the anamnesis of patients would make their identification and adequate treatment possible.

    Full Text Available Background : Chronic obstructive pulmonary diseases (COPD, a broad spectrum of respiratory diseases represents a worldwide problem. Electrocardiographic (ECG findings may help in clinical decision making regarding this disease entity. Aims: To evaluate the extent and diagnostic values of ECG changes among COPD patients suffering from broad spectrum of respiratory diseases. Material & Methods : A hos-pital based cross-sectional study was conducted in Sworoop Rani Nehru Hospital, Allahabad in Eastern Uttar Pradesh (UP, India. A sample of 60 patients attending respiratory diseases OPD for treatment of various respiratory problems including 14 COPD patients was selected randomly during 2000-2001. Patients of respiratory diseases were also evaluated electrocardiographically along with other investiga-tions. Results : Respiratory problems were more common among rural males of low socio-economic group. COPD particularly chronic bronchitis was the commonest respiratory problem next to pulmonary tuberculosis. Inspite of normal heart rate observed in 71.4% COPD patients, ECG changes were present in 35.7% COPD patients. Peaked P-wave was observed in 35.7% COPD patients, whereas duration of QRS complex was abnormal in only 8.1% of the patients. None of the COPD patients showed abnormal P-wave duration. ECG changes were found less sensitive (35.7% but highly specific (95.6%. Conclusion : Diagnostic values of ECG among patients with respiratory problems suggest that COPD patients should be screened electrocardiographically in addition to other clinical investigations.

  8. Biomarkers for Gastroesophageal Reflux in Respiratory Diseases

    2013-01-01

    Full Text Available Gastroesophageal reflux (GER is commonly associated with respiratory symptoms, either through a vagal bronchoconstrictive reflex or through microaspiration of gastric contents. No diagnostic test is available, however, to diagnose when respiratory illnesses are caused by GER and when not, but research in this field has been moving forward. Various biomarkers in different types of biosamples have been studied in this context. The aim of this review is to summarize the present knowledge in this field. GER patients with respiratory diseases seem to have a different biochemical profile from similar patients without GER. Inflammatory biomarkers differ in asthmatics based on GER status, tachykinins are elevated in patients with GER-related cough, and bile acids are elevated in lung transplant patients with GER. However, studies on these biomarkers are often limited by their small size, methods of analysis, and case selections. The two pathogenesis mechanisms are associated with different respiratory illnesses and biochemical profiles. A reliable test to identify GER-induced respiratory disorders needs to be developed. Bronchoalveolar lavage is too invasive to be of use in most patients. Exhaled breath condensate samples need further evaluation and standardization. The newly developed particles in exhaled air measurements remain to be studied further.

    Background: Chronic respiratory diseases such as asthma, allergic rhinitis (AR), chronic obstructive pulmonary disease (COPD), and rhinosinusitis are becoming increasingly prevalent in the Asia-Pacific region. The Asia-Pacific Burden of Respiratory Diseases study examined the disease and economic burden of AR, asthma, COPD, and rhinosinusitis across the Asia-Pacific and more specifically India. Objectives: To estimate the proportion of adults receiving care for asthma, AR, COPD, and rhinosinusitis and assess the economic burden, both direct and indirect of these chronic respiratory disease. Subjects and Methods: Consecutive participants aged ≥18 years with a primary diagnosis of asthma, AR, COPD, or rhinosinusitis were enrolled. Surveys comprising questions about respiratory disease symptoms, healthcare resource utilization, work productivity, and activity impairment were completed by treating physicians and participants during one study visit. Costs, indirect and direct, that contributed to treatment for each of the four respiratory diseases were calculated. Results: A total of 1000 patients were enrolled. Asthma was the most frequent primary diagnosis followed by AR, COPD, and rhinosinusitis. A total of 335 (33.5%) patients were diagnosed with combinations of the four respiratory diseases; the most frequently diagnosed combinations were asthma/AR and rhinosinusitis/AR. Cough or coughing up sputum was the primary reason for the current visit by patients diagnosed with asthma and COPD while AR patients reported a watery, runny nose, and sneezing; patients with rhinosinusitis primarily reported a colored nasal discharge. The mean annual cost per patient was US$637 (SD 806). The most significant driver of direct costs was medications. The biggest cost component was productivity loss. Conclusions: Given the ongoing rapid urbanization of India, the frequency of respiratory diseases and their economic burden will continue to rise. Efforts are required to better

    Full Text Available Background: Agate is a hard silica stone with bands of various colors, which is used in jewelry. The agate grinding workers are exposed to silica dust.Objective: To determine the prevalence of respiratory diseases in agate grinding workers and the associated factors.Methods: In this cross-sectional study, 170 agate grinding workers from Mashhad, northeastern Iran, were examined. Medical and occupational history for respiratory illnesses was taken using respiratory questionnaire of the national program of silicosis control, lung examination, spirometry and chest radiography. Chest x-rays were interpreted according to the International Labor Office (ILO classification system, 2000.Results: The mean±SD of age and work duration of the participants were 31.2±10.1 and 13±8.2 years, respectively. The prevalence of silicosis among agate workers was 12.9% (95% CI: 7.9%–18.0%; 18 workers had simple and 4 had complicated silicosis. There was a significant (p<0.05 relationship between contracting silicosis and exposure duration. 20 (11.7% workers had symptoms consistent with chronic bronchitis and 8 (4.7% showed asthma and asthma-like symptoms. The most frequent disorder observed in spirometry was the restrictive pattern (n=43, 30%. In the agate grinders, clinical and spirometry findings did not match with radiological findings.Conclusion: Agate grinding workers are at increased risk for respiratory diseases, specifically for silicosis and chronic bronchitis. The disease is related to silica dust exposure, poor ventilation and inappropriate personal protection.

    2014-11-01

    Direct observation of violent expirations such as sneezes and coughs events reveal that such flows are multiphase turbulent buoyant clouds with suspended droplets of various sizes. The effects of ambient conditions indoors, such as moisture and temperature, coupled with the water content of such clouds are key in shaping the pathogen footprint emitted by potentially sick individuals. Such pathogen footprint can change the patterns of respiratory disease transmission. We discuss how the fluid dynamics of violent expirations can help inform how.

    2015-01-01

    The anemia of chronic disease is an old disease concept, but contemporary research in the role of proinflammatory cytokines and iron biology has shed new light on the pathophysiology of the condition. Recent epidemiologic studies have connected the anemia of chronic disease with critical illness, obesity, aging, and kidney failure, as well as with the well-established associations of cancer, chronic infection, and autoimmune disease. Functional iron deficiency, mediated principally by the interaction of interleukin-6, the iron regulatory hormone hepcidin, and the iron exporter ferroportin, is a major contributor to the anemia of chronic disease. Although anemia is associated with adverse outcomes, experimental models suggest that iron sequestration is desirable in the setting of severe infection. Experimental therapeutic approaches targeting interleukin-6 or the ferroportin-hepcidin axis have shown efficacy in reversing anemia in either animal models or human patients, although these agents have not yet been approved for the treatment of the anemia of chronic disease.

    2010-01-01

    Chronic obstructive pulmonary disease (COPD) is one of the most important respiratory diseases, characterized by its multicomponent complexity, with chronic inflammation, increased airway resistance and exacerbations. Several drugs are currently available for its treatment, which act on distinct targets. Bronchodilators, especially prolonged-action bronchodilators, are the most potent and there are two groups: beta-2 mimetics and anticholinergics. Inhaled corticosteroids are the main anti-inflammatory drugs but have modest efficacy and their use is reserved for patients with severe disease and frequent exacerbations and/or asthma traits. Associating these three drugs can improve symptom control, improve quality of life and reduce the number of exacerbations. The present article reviews the evidence supporting this triple combination, as well as published studies.

    Mycoplasma ovipneumoniae was isolated from sheep and lambs affected with a respiratory disease. It was established that the pneumonic disease caused by this organism was a severe one, with high mortality rate in young lambs. Adult sheep and older lambs remained chronically affected. Susceptibility varied, depending on the breed of the animals, some imported animals running a more severe course of the disease than the local ones. The disease was artificially induced in lambs at the joint infection with M. ovipneumoniae and P. haemolytica. The morphologic changes in the lungs consisted in a prevailing proliferation of the septal cells and polynuclear cells in the alveoli, an interseptal histiocyte proliferation, and a serous leukocyte infiltration.

    2006-01-01

    Full Text Available Sputum induction by inhalation of hypertonic saline is a noninvasive, simple, cost effective and safe procedure to collect respiratory secre-tions from lung airways for diagnosis of various respiratory diseases. Sputum induction has higher yield in comparison to spontaneous sputum, BAL, bronchial washing and gastric lavage. It is widely used to assess airway inflammation in asthma and chronic obstructive pulmonary disease (COPD. It can be used as a complementary tool to BAL both in research and in clinical monitoring of patients with interstitial lung disease (ILD. The cells, recovered from spontaneous coughing can be used to study lung cancer, respiratory infections and in diagnosis of pneumocystis carinii pneumonia in patients infected with human immunodeficiency virus. In developing countries having high prevalence of pulmonary tuberculosis, sputum induction (SI can increase the diagnostic yield, resulting in better categorization of patients for treatment purposes. It increases case detection rate of smear negative pulmonary tuberculosis specially in area where facili-ties for more invasive and expensive techniques are not available.

    This article reviews the association of chronic renal disease and pregnancy. Included are discussions of guidelines for counseling pregnant women with underlying chronic renal disease who are considering conceiving as well as management of those already pregnant. Specifically highlighted are recent studies that question the validity of using estimated glomerular filtration rate and other formulae and questions of whether we should strive to replace the classic counseling approaches based primarily on serum creatinine levels with guidelines based on chronic kidney disease classification. The article concludes with a review as well as a critique of recent research on the prevalence of preeclampsia in women with underlying chronic renal disease, as well as if women with preeclampsia and underlying kidney disease have accelerated courses toward end-stage renal disease.

    2009-01-01

    Full Text Available The analysis of biomarkers in exhaled breath constituents has recently become of great interest in the diagnosis, treatment and monitoring of many respiratory conditions. Of particular interest is the measurement of fractional exhaled nitric oxide (FENO in breath. Its measurement is noninvasive, easy and reproducible. The technique has recently been standardized by both American Thoracic Society and European Respiratory Society. The availability of cheap, portable and reliable equipment has made the assay possible in clinics by general physicians and, in the near future, at home by patients. The concentration of exhaled nitric oxide is markedly elevated in bronchial asthma and is positively related to the degree of esinophilic inflammation. Its measurement can be used in the diagnosis of bronchial asthma and titration of dose of steroids as well as to identify steroid responsive patients in chronic obstructive pulmonary disease. In primary ciliary dyskinesia, nasal NO is diagnostically low and of considerable value in diagnosis. Among lung transplant recipients, FENO can be of great value in the early detection of infection, bronchioloitis obliterans syndrome and rejection. This review discusses the biology, factors affecting measurement, and clinical application of FENO in the diagnosis and management of respiratory diseases.

    2015-06-01

    The burden of chronic diseases, including occupational respiratory diseases (ORDs), is increasing worldwide. Nevertheless, epidemiological data on these conditions are scarce in most countries. Therefore, it is important to conduct surveillance to monitor ORDs, particularly in developing countries, where the working population is especially vulnerable and the health system infrastructure is usually weak. This article provides a general framework for the implementation of ORD surveillance in developing countries. The main objectives of surveillance are to describe incidence and prevalence of ORDs, as well as to identify sentinel events and new associations between occupational exposures and health outcomes. Diseases with high morbidity and mortality and those in which early diagnosis with standardized tests are available are especially suitable for surveillance activities. Simple strategies, preferably using existing resources and technology, are the best option for surveillance in developing countries. This article offers examples of specific surveillance systems that are in place in Brazil, China, Cuba, India, and South Africa.

    Full Text Available Chronic respiratory disease occurrence in urban population is creating burden on economic growth and challenges to public health management. This descriptive, prevalence study was designed to gather data on risk factor related association of respiratory diseases occurrence with information on sign, symptoms and treatment modalities. Questionnaire based personal interview was conducted on selected patients with well documented respiratory problem on demographic, biosocial, educational, occupational and economic background. Body weight, height, blood pressure, details of treatment modalities, sign and symptoms were recorded from hospital data. The prevalence rates were presented as percentage and 95% confidence interval estimated and analyzed by person’s chi-square test. Age, number of children more than three (p<0.0001, family members more than three (p<0.01, overcrowding (p<0.0001, low socioeconomic class (p<0.0001, unhygienic surrounding (p<0.001, education below secondary level (p<0.01, low to normal BMI (p<0.002 and chronic smoking habit (p<0.001 showed significant risk factor related association with occurrence of respiratory disease. Most frequently found sign and symptom are apnea, tiredness, nausea, coughing and nose tickling. Marital status, source of drinking water, cooking fuel, occupation, employment status, income, respiratory rate, sleep pattern and regular use of other medication does not show any co-relation with respiratory disease occurrence. The significant risk factor for respiratory disease occurrence is aging, unhygienic environment, low level education, overcrowding and smoking.

    Full Text Available Abstract Background Particulate matter air pollution has been associated with adverse health effects. The fraction of ambient particles that are mainly responsible for the observed health effects is still a matter of controversy. Better characterization of the health relevant particle fraction will have major implications for air quality policy since it will determine which sources should be controlled. The RUPIOH study, an EU-funded multicentre study, was designed to examine the distribution of various ambient particle metrics in four European cities (Amsterdam, Athens, Birmingham, Helsinki and assess their health effects in participants with asthma or COPD, based on a detailed exposure assessment. In this paper the association of central site measurements with respiratory symptoms and restriction of activities is examined. Methods At each centre a panel of participants with either asthma or COPD recorded respiratory symptoms and restriction of activities in a diary for six months. Exposure assessment included simultaneous measurements of coarse, fine and ultrafine particles at a central site. Data on gaseous pollutants were also collected. The associations of the 24-hour average concentrations of air pollution indices with the health outcomes were assessed in a hierarchical modelling approach. A city specific analysis controlling for potential confounders was followed by a meta-analysis to provide overall effect estimates. Results A 10 μg/m3 increase in previous day coarse particles concentrations was positively associated with most symptoms (an increase of 0.6 to 0.7% in average and limitation in walking (OR= 1.076, 95% CI: 1.026-1.128. Same day, previous day and previous two days ozone concentrations were positively associated with cough (OR= 1.061, 95% CI: 1.013-1.111; OR= 1.049, 95% CI: 1.016-1.083 and OR= 1.059, 95% CI: 1.027-1.091, respectively.

    2007-12-01

    Pasteurella multocida is a pathogenic Gram-negative bacterium that has been classified into three subspecies, five capsular serogroups and 16 serotypes. P. multocida serogroup A isolates are bovine nasopharyngeal commensals, bovine pathogens and common isolates from bovine respiratory disease (BRD), both enzootic calf pneumonia of young dairy calves and shipping fever of weaned, stressed beef cattle. P. multocida A:3 is the most common serotype isolated from BRD, and these isolates have limited heterogeneity based on outer membrane protein (OMP) profiles and ribotyping. Development of P. multocida-induced pneumonia is associated with environmental and stress factors such as shipping, co-mingling, and overcrowding as well as concurrent or predisposing viral or bacterial infections. Lung lesions consist of an acute to subacute bronchopneumonia that may or may not have an associated pleuritis. Numerous virulence or potential virulence factors have been described for bovine respiratory isolates including adherence and colonization factors, iron-regulated and acquisition proteins, extracellular enzymes such as neuraminidase, lipopolysaccharide, polysaccharide capsule and a variety of OMPs. Immunity of cattle against respiratory pasteurellosis is poorly understood; however, high serum antibodies to OMPs appear to be important for enhancing resistance to the bacterium. Currently available P. multocida vaccines for use in cattle are predominately traditional bacterins and a live streptomycin-dependent mutant. The field efficacy of these vaccines is not well documented in the literature.

    Rural-urban differences in the prevalence of chronic diseases in the adult population of northeast China are examined. The Jilin Provincial Chronic Disease Survey used personal interviews and physical measures to research the presence of a range of chronic diseases among a large sample of rural and urban provincial residents aged 18 to 79 years (N = 21 435). Logistic regression analyses were used. After adjusting for age and gender, rural residents had higher prevalence of hypertension, chronic ischemic heart disease, cerebrovascular disease, chronic low back pain, arthritis, chronic gastroenteritis/peptic ulcer, chronic cholecystitis/gallstones, and chronic lower respiratory disease. Low education, low income, and smoking increased the risk of chronic diseases in rural areas. Reducing rural-urban differences in chronic disease presents a formidable public health challenge for China. The solution requires focusing attention on issues endemic to rural areas such as poverty, lack of chronic disease knowledge, and the inequality in access to primary care.

    Chronic Non-Communicable Diseases are the main source of disease burden in Brazil. In 2011, the Brazilian Ministry of Health launched the Strategic Plan of Action for Management of Chronic Non-Communicable Diseases focusing on population-based interventions to manage cardiovascular diseases, diabetes, cancer, and chronic respiratory diseases mainly through fighting tobacco use, unhealthy diets, physical inactivity and the harmful use of alcohol. Although a significant number of scientific studies on chronic diseases and their risk factors have been undertaken in Brazil, few are of cohort design. In this context, the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a cohort study of 15,105 Brazilian public servants reflects the reality of high prevalences of diabetes, hypertension and the main chronic diseases risk factors. The diversity of information that the Study will produce can provide important input to better understand the causes of chronic diseases and to support public policies for fighting them.

    Full Text Available Nanotechnology is an emerging science with the potential to create new materials and strategies involving manipulation of matter at the nanometer scale (<100 nm. With size-dependent properties, nanoparticles have introduced a new paradigm in pharmacotherapy – the possibility of cell-targeted drug delivery with minimal systemic side effects and toxicity. The present review provides a summary of published findings, especially regarding to nanoparticle formulations for lung diseases. The available data have shown some benefits with nanoparticle-based therapy in the development of the disease and lung remodeling in respiratory diseases. However, there is a wide gap between the concepts of nanomedicine and the published experimental data and clinical reality. In addition, studies are still required to determine the potential of nanotherapy and the systemic toxicity of nanomaterials for future human use.

    Hyaluronan, a ubiquitous naturally occurring glycosaminoglycan, is a major component of the extracellular matrix, where it participates in biological processes that include water homeostasis, cell-matrix signaling, tissue healing, inflammation, angiogenesis, and cell proliferation and migration. There are emerging data that hyaluronan and its degradation products have an important role in the pathobiology of the respiratory tract. We review the role of hyaluronan in respiratory diseases and present evidence from published literature and from clinical practice supporting hyaluronan as a novel treatment for respiratory diseases. Preliminary data show that aerosolized exogenous hyaluronan has beneficial activity against airway inflammation, protects against bronchial hyperreactivity and remodeling, and disrupts the biofilm associated with chronic infection. This suggests a role in airway diseases with a predominant inflammatory component such as rhinosinusitis, asthma, chronic obstructive pulmonary disease, cystic fibrosis, and primary ciliary dyskinesia. The potential for hyaluronan to complement conventional therapy will become clearer when data are available from controlled trials in larger patient populations.

    2016-11-01

    Healthcare workers (HCWs) are exposed to a range of high and low molecular weight agents that are allergic sensitizers or irritants including cleaners and disinfectants, natural rubber latex, and various medications. Studies have shown that exposed HCWs are at risk for work-related rhinitis and asthma (WRA). Work-related rhinitis may precede development of WRA and should be considered as an early marker of WRA. Avoidance of causative exposures through control strategies such as elimination, substitution, engineering controls, and process modification is the preferred primary prevention strategy for preventing development of work-related allergic diseases. There is limited evidence for the effectiveness of respirators in preventing occupational asthma. If sensitizer-induced WRA is diagnosed, it is important to avoid further exposure to the causative agent, preferably by more rigorous application of exposure control strategies to the workplace. This review focuses on allergic occupational respiratory diseases in HCWs.

    2016-08-01

    To identify determinants of respiratory disease progression in late-onset Pompe disease (LOPD), we studied relationships between pulmonary function, respiratory muscle strength, gas exchange, and respiratory control. Longitudinal evaluation of 22 LOPD patients (mean age 38 years) was performed at 6-month intervals for 6-24 months. Measurements included vital capacity (VC), maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), tidal volume (VT), dead space (VD), and ventilatory response to CO2. Although reduction in VC correlated with MIP and MEP (p respiratory failure, is tightly linked to the degree of respiratory muscle weakness and severity of pulmonary dysfunction in LOPD patients. Reductions in CO2 clearance efficiency and ventilatory responsiveness may contribute to the development of chronic daytime hypercapnia.

    Helicobacter pylori (H. pylori) is a major cause of chronic gastritis and gastric ulcers and considerable evidence supports the notion that infection with this bacterium is also associated with gastric malignancy in addition to various other conditions including pulmonary, vascular and autoimmune disorders. Gastric juice infected with H. pylori might play an important role in upper respiratory tract infection. Although direct and/or indirect mechanisms might be involved in the association between H. pylori and upper respiratory tract diseases, the etiological role of H. pylori in upper respiratory tract disorders has not yet been fully elucidated. Although various studies over the past two decades have suggested a relationship between H. pylori and upper respiratory tract diseases, the findings are inconsistent. The present overview describes the outcomes of recent investigations into the impact of H. pylori on upper respiratory tract and adjacent lesions.

P300 was also significantly delayed whether hypoxia occurred with or without hypercapnia.Conclusion: Results show a significant delay of P300 latency in patients with severe and mild respiratory failure. This was associated with subclinical encephalopathy in most patients, evidenced by a near-normal MMSE score. Apart from confirming the importance of P300 latency measurement as a marker of respiratory encephalopathy, this study asserts the causal relationship between hypoxemia and cognitive derangement. Furthermore, it promotes the early use of oxygen therapy in a selected group of patients with mild or moderate respiratory failure, who have responsibilities which involve taking rapid critical decisions.Keywords: event-related evoked potentials, hypoxic–hypercapnic encephalopathy, respiratory failure, chronic respiratory encephalopathy

    2006-12-01

    The purpose of this review was to examine the impact of varying degrees of renal insufficiency on pregnancy outcome in women with chronic renal disease. Our search of the literature did not reveal any randomized clinical trials or meta-analyses. The available information is derived from opinion, reviews, retrospective series, and limited observational series. It appears that chronic renal disease in pregnancy is uncommon, occurring in 0.03-0.12% of all pregnancies from two U.S. population-based and registry studies. Maternal complications associated with chronic renal disease include preeclampsia, worsening renal function, preterm delivery, anemia, chronic hypertension, and cesarean delivery. The live birth rate in women with chronic renal disease ranges between 64% and 98% depending on the severity of renal insufficiency and presence of hypertension. Significant proteinuria may be an indicator of underlying renal insufficiency. Management of pregnant women with underlying renal disease should ideally entail a multidisciplinary approach at a tertiary center and include a maternal-fetal medicine specialist and a nephrologist. Such women should receive counseling regarding the pregnancy outcomes in association with maternal chronic renal disease and the effect of pregnancy on renal function, especially within the ensuing 5 years postpartum. These women will require frequent visits and monitoring of renal function during pregnancy. Women whose renal disease is further complicated by hypertension should be counseled regarding the increased risk of adverse outcome and need for blood pressure control. Some antihypertensives, especially angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers, should be avoided during pregnancy, if possible, because of the potential for both teratogenic (hypocalvaria) and fetal effects (renal failure, oliguria, and demise).

    T lymphocytes predominantly express delayed rectifier K(+)-channels (Kv1.3) in their plasma membranes. Patch-clamp studies revealed that the channels play crucial roles in facilitating the calcium influx necessary to trigger lymphocyte activation and proliferation. Using selective channel inhibitors in experimental animal models, in vivo studies further revealed the clinically relevant relationship between the channel expression and the development of chronic respiratory diseases, in which chronic inflammation or the overstimulation of cellular immunity in the airways is responsible for the pathogenesis. In chronic respiratory diseases, such as chronic obstructive pulmonary disease, asthma, diffuse panbronchiolitis and cystic fibrosis, in addition to the supportive management for the symptoms, the anti-inflammatory effects of macrolide antibiotics were shown to be effective against the over-activation or proliferation of T lymphocytes. Recently, we provided physiological and pharmacological evidence that macrolide antibiotics, together with calcium channel blockers, HMG-CoA reductase inhibitors, and nonsteroidal anti-inflammatory drugs, effectively suppress the Kv1.3-channel currents in lymphocytes, and thus exert anti-inflammatory or immunomodulatory effects. In this review article, based on the findings obtained from recent in vivo and in vitro studies, we address the novel therapeutic implications of targeting the lymphocyte Kv1.3-channels for the treatment of chronic or acute respiratory diseases.

  15. Rhinovirus genome variation during chronic upper and lower respiratory tract infections.

    Directory of Open Access Journals (Sweden)

    Caroline Tapparel

    Full Text Available Routine screening of lung transplant recipients and hospital patients for respiratory virus infections allowed to identify human rhinovirus (HRV in the upper and lower respiratory tracts, including immunocompromised hosts chronically infected with the same strain over weeks or months. Phylogenetic analysis of 144 HRV-positive samples showed no apparent correlation between a given viral genotype or species and their ability to invade the lower respiratory tract or lead to protracted infection. By contrast, protracted infections were found almost exclusively in immunocompromised patients, thus suggesting that host factors rather than the virus genotype modulate disease outcome, in particular the immune response. Complete genome sequencing of five chronic cases to study rhinovirus genome adaptation showed that the calculated mutation frequency was in the range observed during acute human infections. Analysis of mutation hot spot regions between specimens collected at different times or in different body sites revealed that non-synonymous changes were mostly concentrated in the viral capsid genes VP1, VP2 and VP3, independent of the HRV type. In an immunosuppressed lung transplant recipient infected with the same HRV strain for more than two years, both classical and ultra-deep sequencing of samples collected at different time points in the upper and lower respiratory tracts showed that these virus populations were phylogenetically indistinguishable over the course of infection, except for the last month. Specific signatures were found in the last two lower respiratory tract populations, including changes in the 5'UTR polypyrimidine tract and the VP2 immunogenic site 2. These results highlight for the first time the ability of a given rhinovirus to evolve in the course of a natural infection in immunocompromised patients and complement data obtained from previous experimental inoculation studies in immunocompetent volunteers.

    Full Text Available Recurrent respiratory papillomatosis is a relatively uncommon disease that presents clinically with symptoms ranging from hoarseness to severe dyspnea. Human papilloma virus types 6 and 11 are important in the etiology of papillomas and are most probably transmitted from mother to child during birth. Although spontaneous remission is frequent, pulmonary spread and/or malignant transformation resulting in death has been reported. CO2 laser evaporation of papillomas and adjuvant drug therapy using lymphoblastoid interferon-alpha are the most common treatments. However, several other treatments have been tried, with varying success. In the present report, a case of laryngeal papillomatosis presenting with chronic stridor and delayed speech is described.

    Chronic respiratory diseases such as asthma, allergic rhinitis (AR), chronic obstructive pulmonary disease (COPD), and rhinosinusitis are becoming increasingly prevalent in the Asia-Pacific region. The Asia-Pacific Burden of Respiratory Diseases (APBORD) study was a cross-sectional, observational study which examined the disease and economic burden of AR, asthma, COPD, and rhinosinusitis across Asia-Pacific using 1 standard protocol. Here we report symptoms, healthcare resource use (HCRU), work impairment, and associated cost in Taiwan.Consecutive participants aged ≥ 18 years presenting to a physician with symptoms meeting the diagnostic criteria for a primary diagnosis of asthma, AR, COPD, or rhinosinusitis were enrolled. Participants and their treating physician completed surveys detailing respiratory symptoms, HCRU, work productivity, and activity impairment. Costs including direct medical costs and indirect costs associated with lost work productivity were calculated.The study enrolled 1001 patients. AR was the most frequent primary diagnosis (31.2%). A quarter of patients presented with a combination of respiratory diseases, with AR and asthma being the most frequent combination (14.1%). Cough or coughing up phlegm was the primary reason for the medical visit for patients with asthma and COPD, whereas nasal symptoms (watery runny nose, blocked nose, and congestion) were the primary reasons for AR and rhinosinusitis. Specialists were the most frequently used healthcare resource by patients with AR (26.1%), asthma (26.4%), COPD (26.6%), and rhinosinusitis (47.3%). The mean annual cost per patient with a respiratory disease was US$4511 (SD 5395). The cost was almost double for employed patients (US$8047, SD 6175), with the majority attributable to lost productivity.Respiratory diseases have a significant impact on disease burden in Taiwan. Treatment strategies that prevent lost work productivity could greatly reduce the economic burden of these diseases.

    Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in developed countries and it is now considered a risk factor for cardiovascular disease. Evidence linking NAFLD to the development and progression of chronic kidney disease (CKD) is emerging as a popular area of scientific interest. The rise in simultaneous liver-kidney transplantation as well as the significant cost associated with the presence of chronic kidney disease in the NAFLD population make this entity a worthwhile target for screening and therapeutic intervention. While several cross-sectional and case control studies have been published to substantiate these theories, very little data exists on the underlying cause of NAFLD and CKD. In this review, we will discuss the most recent publications on the diagnosis of NAFLD as well new evidence regarding the pathophysiology of NAFLD and CKD as an inflammatory disorder. These mechanisms include the role of obesity, the renin-angiotensin system, and dysregulation of fructose metabolism and lipogenesis in the development of both disorders. Further investigation of these pathways may lead to novel therapies that aim to target the NAFLD and CKD. However, more prospective studies that include information on both renal and liver histology will be necessary in order to understand the relationship between these diseases.

    Full Text Available Background: National Institute of Environmental Health Sciences (NIEHS scientists shows that long-term exposure to air pollutants increases the risk of respiratory diseases such as allergies, asthma, chronic obstructive pulmonary disease, and lung cancer. Children and the elderly are particularly vulnerable to the health effects of ozone, fine particles, and other airborne toxicants. Air pollution factors are considered as one of the underlying causes of respiratory diseases. This study aimed to determine the association of respiratory diseases documented in medical records and air pollution (Map distribution of accumulation in Isfahan province, Iran. By plotting the prevalence and spatial distribution maps, important differences from different points can be observed. Materials and Methods: The geographic information system (GIS, pollutant standards index (PSI measurements, and remote Sensing (RS technology were used after entering data in the mapping information table; spatial distribution was mapped and distribution of Geographical Epidemiology of Respiratory Diseases in Isfahan province (Iran was determined in this case study from 2005 to 2009. Results: Space with tracing the distribution of respiratory diseases was scattered based on the distribution of air pollution in the points is an important part of this type of diseases in Isfahan province where air pollution was more abundant. Conclusion: The findings of this study emphasis on the importance of preventing the exposure to air pollution, and to control air pollution product industries, to improve work environmental health, and to increase the health professionals and public knowledge in this regard.

    2008-06-01

    Studies have shown that most patients diagnosed with chronic Lyme disease either have no objective evidence of previous or current infection with Borrelia burgdorferi or are patients who should be classified as having post-Lyme disease syndrome, which is defined as continuing or relapsing nonspecific symptoms (such as fatigue, musculoskeletal pain, and cognitive complaints) in a patient previously treated for Lyme disease. Despite extensive study, there is currently no clear evidence that post-Lyme disease syndrome is caused by persistent infection with B burgdorferi. Four randomized placebo-controlled studies have shown that antibiotic therapy offers no sustained benefit to patients who have post-Lyme disease syndrome. These studies also showed a substantial placebo effect and a significant risk of treatment-related adverse events. Further research to elucidate the mechanisms underlying persistent symptoms after Lyme disease and controlled trials of new approaches to the treatment and management of these patients are needed.

    A group of patients between 35 and 65 years old with chronic prostatitis were examined for the presence of Becherew's disease. In this connection the New York and Roman criterions for morbus Bechterew were applied. There were found one ankyosing spondylarthritis, one ankylosis of the sacroiliac joint, and 11 times a tentative sacroileitis were stated. Altogether the proved and tentative findings were only 3.68 per cent of all examinations. In our countries the morbus Bechterew is found in 0,21 per cent of the normal population. So the protion of the Bechterew's disease in patients with chronic prostatitis is indeed a little higher than average, but not so frequent as often pretended in recent times. After a second series 58 patients being treated because of Bechterew's disease of different stages and different terms were examined for the possibility of a simultaneously elapsing chronic prostatitis. A chronic prostatitis was found in 38 per cent of these patients which correspondents to the incidence published in literature for the medium-age manhood. Nobody of the test persons had complaints on the part of the urologenital tract.

    2008-07-01

    There is much controversy about the treatment of Lyme disease with respect to 2 poorly defined entities: "chronic Lyme disease" and "posttreatment Lyme disease syndrome." In the absence of direct evidence that these conditions are the result of a persistent infection, some mistakenly advocate extended antibiotic therapy (>/=6 months), which can do great harm and has resulted in at least 1 death. The purpose of this brief report is to review what is known from clinical research about these conditions to assist both practicing physicians and lawmakers in making sound and safe decisions with respect to treatment.

    Exercise training has become a cornerstone of Pulmonary Rehabilitation. Since the nineties, the effectiveness in clinically relevant improvements in exercise capacity and health-related quality of life has been proved. Current guidelines (Evidence A) recommend high intensity continuous exercise for lower extremities as the most effective exercise modality, however, for some patients it is often difficult to initiate such an exercise programme due to the limitation of dyspnoea or leg fatigue. In recent years, special relevance has been given to the integration of other modalities of exercise (continuous versus interval, aerobic versus strength, inclusion or not of respiratory muscle training). The authors carry out a review of the current literature concerning exercise training in chronic pulmonary disease and this highlights the role of tailored exercise to break the vicious cycle of dyspnoea and inactivity.

    2007-02-01

    Full Text Available As doenças neuromusculares prejudicam a renovação do ar alveolar e, por esta razão, produzem insuficiência respiratória crônica. A instalação da insuficiência respiratória pode acontecer de modo agudo, como nos traumas, ou ser lenta ou rapidamente progressiva, como na esclerose lateral amiotrófica, distrofias musculares, doença da placa mioneural, etc. O comprometimento da musculatura respiratória prejudica também a eficiência da tosse e, no estado atual da terapêutica disponível no Brasil para estes doentes, pode-se dizer que a morbimortalidade nestes indivíduos está mais associada ao fato de que eles tossem mal do que de que ventilam mal. Nesta revisão, uma breve compilação histórica procura mostrar a evolução das órteses e próteses respiratórias, desde o final do século XIX até agora, com o objetivo de apresentar as opções de máquinas disponíveis para o suporte e substituição da ventilação nas doenças neuromusculares. Além disso, são enfatizados os elementos fundamentais para o diagnóstico da hipoventilação alveolar e da falência do mecanismo protetor da tosse: história clínica, determinação do pico de fluxo da tosse, medida da pressão expiratória máxima e da pressão inspiratória máxima, espirometria em dois decúbitos (sentado e supino, oximetria de pulso, capnografia e polissonografia. São apresentados os valores limites disponíveis na literatura tanto para a indicação do suporte noturno da ventilação como para a extensão do suporte para o período diurno. As manobras para incremento da eficiência da tosse são aqui também discutidas, assim como o momento adequado para sua introdução.Neuromuscular diseases affect alveolar air exchange and therefore cause chronic respiratory failure.

    Laboratory and observational research studies suggest that vitamin D and marine omega-3 fatty acids may reduce risk for pneumonia, acute exacerbations of respiratory diseases including chronic obstructive lung disease (COPD) or asthma, and decline of lung function, but prevention trials with adequate dosing, adequate power, and adequate time to follow-up are lacking. The ongoing Lung VITAL study is taking advantage of a large clinical trial-the VITamin D and OmegA-3 TriaL (VITAL)--to conduct the first major evaluation of the influences of vitamin D and marine omega-3 fatty acid supplementation on pneumonia risk, respiratory exacerbation episodes, asthma control and lung function in adults. VITAL is a 5-year U.S.-wide randomized, double-blind, placebo-controlled, 2 × 2 factorial trial of supplementation with vitamin D3 ([cholecalciferol], 2000 IU/day) and marine omega-3 FA (Omacor® fish oil, eicosapentaenoic acid [EPA]+docosahexaenoic acid [DHA], 1g/day) for primary prevention of CVD and cancer among men and women, at baseline aged ≥50 and ≥55, respectively, with 5107 African Americans. In a subset of 1973 participants from 11 urban U.S. centers, lung function is measured before and two years after randomization. Yearly follow-up questionnaires assess incident pneumonia in the entire randomized population, and exacerbations of respiratory disease, asthma control and dyspnea in a subpopulation of 4314 randomized participants enriched, as shown in presentation of baseline characteristics, for respiratory disease, respiratory symptoms, and history of cigarette smoking. Self-reported pneumonia hospitalization will be confirmed by medical record review, and exacerbations will be confirmed by Center for Medicare and Medicaid Services data review.

    Sophie Köndgen

    Full Text Available Pasteurella multocida can cause a variety of diseases in various species of mammals and birds throughout the world but nothing is known about its importance for wild great apes. In this study we isolated P. multocida from wild living, habituated chimpanzees from Taï National Park, Côte d'Ivoire. Isolates originated from two chimpanzees that died during a respiratory disease outbreak in 2004 as well as from one individual that developed chronic air-sacculitis following this outbreak. Four isolates were subjected to a full phenotypic and molecular characterisation. Two different clones were identified using pulsed field gel electrophoresis. Multi Locus Sequence Typing (MLST enabled the identification of previous unknown alleles and two new sequence types, ST68 and ST69, were assigned. Phylogenetic analysis of the superoxide dismutase (sodA gene and concatenated sequences from seven MLST-housekeeping genes showed close clustering within known P. multocida isolated from various hosts and geographic locations. Due to the clinical relevance of the strains described here, these results make an important contribution to our knowledge of pathogens involved in lethal disease outbreaks among endangered great apes.

    Full Text Available It is easier to prevent a disease than to cure it. This postulate is a foundation stone of the contemporary medicine, furthermore its mission. The Chronic Kidney Diseases (CKD, amongst them the Chronic Pyelonephrites (CP and the mass kidney reduction  take an important  place in human pathologies in general, and in particular in renal ones. The Chronic Pyelonephrites  are chronic renal pathologies, which on one side are of various causes and on the other side are multi systemic. At the same time they tend, earlier or later, depending on their course, to bring the patient towards the Chronic Kidney Insufficiency  in stage of uremia, consequently in need of substitution therapies e.g. dialysis, peritoneum dialysis or transplant. It is worthy to emphasize that from the prevention and correct cure of CP make profit the patients, the family, the state and in the last analyses  the entire society, because in that way the budget expense destined for the fore going substitution cures, dialysis, peritoneum dialysis or transplant, is considerably  reduced. The same should be mentioned  in relation to the CP and the mass kidney reduction, speaking about our country, which are still at the first place as the very cause of Chronic Kidney  Insufficiencies (CRI, later on advancing toward uremia and terminal uremia along with its grave consequences. In general  the very foundation of the CP is on  the  infections of urinary roads, in particular on the complicated ones, among them it should be mentioned-congenital kidney anomalies, renal calculosis  so much present in our country, and pathologies of segment or vesical-ureteral reflux, and rarely the pathologies of prostate.

    2014-01-01

    Full Text Available Irrespective of aetiology, infectious respiratory diseases of sheep and goats contribute to 5.6 percent of the total diseases of small ruminants. These infectious respiratory disorders are divided into two groups: the diseases of upper respiratory tract, namely, nasal myiasis and enzootic nasal tumors, and diseases of lower respiratory tract, namely, peste des petits ruminants (PPR, parainfluenza, Pasteurellosis, Ovine progressive pneumonia, mycoplasmosis, caprine arthritis encephalitis virus, caseous lymphadenitis, verminous pneumonia, and many others. Depending upon aetiology, many of them are acute and fatal in nature. Early, rapid, and specific diagnosis of such diseases holds great importance to reduce the losses. The advanced enzyme-linked immunosorbent assays (ELISAs for the detection of antigen as well as antibodies directly from the samples and molecular diagnostic assays along with microsatellites comprehensively assist in diagnosis as well as treatment and epidemiological studies. The present review discusses the advancements made in the diagnosis of common infectious respiratory diseases of sheep and goats. It would update the knowledge and help in adapting and implementing appropriate, timely, and confirmatory diagnostic procedures. Moreover, it would assist in designing appropriate prevention protocols and devising suitable control strategies to overcome respiratory diseases and alleviate the economic losses.

  20. Vouchers for chronic disease care.

    Science.gov (United States)

    Watts, Jennifer J; Segal, Leonie

    2008-08-01

    This paper explores the economic implications of vouchers for chronic disease management with respect to achieving objectives of equity and efficiency. Vouchers as a payment policy instrument for health care services have a set of properties that suggest they may address both demand-side and supply-side issues, and contribute to equity and efficiency. They provide a means whereby health care services can be targeted at selected groups, enabling consumer choice of provider, and encouraging competition in the supply of health services. This analysis suggests that, when structured appropriately, vouchers can support consumers to choose services that will meet their health care needs and encourage competition among providers. Although they may not be appropriate across the entire health care system, there are features of vouchers that make them a potentially attractive option, especially for the management of chronic disease.

    Numerous lines of evidence implicate a role of myeloperoxidase (MPO) in the pathogenesis of cardiovascular disease (CVD). It is a well accepted fact that patients with chronic kidney disease (CKD) are at an increased risk for CVD. MPO is a pro-oxidant enzyme which could be involved in the increased susceptibility of these patients to CVD. Hence, the levels of plasma MPO was determined in healthy controls as well as in patients with CKD [stratified with the level of their kidney failure as CKD...

    Asia-Pacific Burden of Respiratory Diseases (APBORD) was a cross-sectional, observational study examining the burden of respiratory disease in adults across 6 Asia-Pacific countries.This article reports symptoms, healthcare resource utilization (HCRU), work impairment and cost burden associated with allergic rhinitis (AR), asthma, chronic obstructive pulmonary disease (COPD), and rhinosinusitis in Thailand.Consecutive participants aged ≥18 years with a primary diagnosis of AR, asthma, COPD, or rhinosinusitis were enrolled at 4 hospitals in Thailand during October 2012 and October 2013. Participants completed a survey detailing respiratory symptoms, HCRU, work productivity, and activity impairment. Locally sourced unit costs were used in the calculation of total costs.The study enrolled 1000 patients. The most frequent primary diagnosis was AR (44.2%), followed by rhinosinusitis (24.1%), asthma (23.7%), and COPD (8.0%). Overall, 316 (31.6%) of patients were diagnosed with some combination of the 4 diseases. Blocked nose or congestion (17%) and cough or coughing up phlegm (16%) were the main reasons for the current medical visit. The mean annual cost for patients with a respiratory disease was US$1495 (SD 3133) per patient. Costs associated with work productivity loss were the principal contributor for AR and rhinosinusitis patients while medication costs were the highest contributor for asthma and COPD patients.The study findings highlight the burden associated with 4 prevalent respiratory diseases in Thailand. Thorough investigation of concomitant conditions and improved disease management may help to reduce the burden of these respiratory diseases.

    Background Diagnosis and treatment for respiratory symptoms (RSs) of gastroesophageal reflux disease (GERD) is more difficult than that for common esophageal symptoms. The goal of this study was to evaluate the efficacy and safety of radiofrequency (RF) treatment on RSs of GERD in a preliminary 12-month follow-up observation.Methods From April 2006 to October 2008,505 GERD patients with mainly respiratory presentations such as wheezing,chronic cough or hoarseness,were treated by endoscopic RF. A questionnaire was completed before and after treatment,using a six-point scale ranging from 0 to 5 to assess symptom severity and frequency. The symptom score was the sum of frequency and severity.Results Symptom scores were significantly improved at the end of the follow-up period. The mean heartburn score decreased from 5.31 to 1.79. The mean regurgitation score decreased from 5.02 to 1.64;mean cough score decreased from 6.77 to 2.85;mean wheezing score decreased from 7.83 to 3.07;and mean hoarseness score decreased from 5.13 to 1.81 (P <0.01). No major complications or deaths occurred. Minor complications included temporary post-procedural retrosternal unease or pain (n=106;21.0%),mild fever (n=86;17.0%),transient nausea/vomiting (n=97;19.2%),and transient dysphagia (n=42;9.3%). Thirty-five (6.9%) patients had recurrence of symptoms. Endoscopic RF treatment was repeated in six patients,and laparoscopic fundoplication was performed in seven.Conclusion Endoscopic RF is an effective and safe means to treat RSs in patients with GERD.

    Acute respiratory tract infections are of paramount importance in the poultry industry. Avian influenza virus (AIV), infectious bronchitis virus (IBV), Newcastle disease virus (NDV), avian pneumovirus (APV), and Mycoplasma gallisepticum (MG) have been recognized as the most important pathogens in poultry. In this study, trachea swabs from 115 commercial broiler chicken flocks that suffered from respiratory disease were tested for AIV subtype H9N2, IBV, NDV, and APV by using reverse transcription PCR and for MG by using PCR. The PCR and reverse transcription PCR results showed that 13 and 14.8% of these flocks were infected with NDV and IBV, respectively, whereas 5.2, 6.0, 9.6, 10.4, 11.3, and 15.7% of these flocks were infected with both NDV and MG; MG and APV; IBV and NDV; IBV and MG; NDV and AIV; and IBV and AIV, respectively. Furthermore, 2.6% of these flocks were infected with IBV, NDV, and APV at the same time. On the other hand, 11.3% of these flocks were negative for the above-mentioned respiratory diseases. Our data showed that the above-mentioned respiratory pathogens were the most important causes of respiratory disease in broiler chickens in Jordan. Further studies are necessary to assess circulating strains, economic losses caused by infections and coinfections of these pathogens, and the costs and benefits of countermeasures. Furthermore, farmers need to be educated about the signs and importance of these pathogens.

    BACKGROUND: Hairdressing is one of the professions with the highest risk of occupational skin and respiratory diseases. The incidence of these diseases in hairdressing apprentices has been studied only sparsely. OBJECTIVE: To determine the incidence of skin and respiratory diseases in hairdressing...... apprentices, and to explore whether hairdressing apprentices leave the trade during training because of these diseases. METHODS: A 3-year follow-up questionnaire study was conducted among 248 hairdressing apprentices and a control group comprising 816 young adults from the general population. RESULTS.......8% of the hairdressing apprentices had left the trade, and 70.3% of these had left because of health complaints. The most frequently reported reasons for leaving were musculoskeletal pain (47.4%) and skin diseases (47.4%), followed by respiratory symptoms (23.7%). CONCLUSIONS: Hairdressing apprentices are at increased...

    Air pollution of anthropogenic origin is largely from the combustion of biomass (e.g., wood), fossil fuels (e.g., cars and trucks), incinerators, landfills, agricultural activities and tobacco smoke. Air pollution is a complex mixture that varies in space and time, and contains hundreds of compounds including volatile organic compounds (e.g., benzene), metals, sulphur and nitrogen oxides, ozone and particulate matter (PM). PM0.1 (ultrafine particles (UFP)), those particles with a diameter less than 100 nm (includes nanoparticles (NP)) are considered especially dangerous to human health and may contribute significantly to the development of numerous respiratory and cardiovascular diseases such as chronic obstructive pulmonary disease (COPD) and atherosclerosis. Some of the pathogenic mechanisms through which PM0.1 may contribute to chronic disease is their ability to induce inflammation, oxidative stress and cell death by molecular mechanisms that include transcription factors such as nuclear factor κB (NF-κB) and nuclear factor (erythroid-derived 2)-like 2 (Nrf2). Epigenetic mechanisms including non-coding RNA (ncRNA) may also contribute towards the development of chronic disease associated with exposure to PM0.1. This paper highlights emerging molecular concepts associated with inhalational exposure to PM0.1 and their ability to contribute to chronic respiratory and systemic disease. PMID:28125025

    2002-09-01

    Lyme disease is currently the most common vector-borne illness in the United States. The disease is multisystemic, and chronic disease, in particular, may be associated with neuropsychological deficits. However, to date, only a few empirical studies exist, which examine the neuropsychological sequelae associated with chronic Lyme disease. A review of the literature shows that the deficits observed in adults with chronic Lyme disease are generally consistent with the deficits that can be seen in processes with primarily frontal systems involvement. These observations are generally consistent with neuroradiologic findings. The clinical presentation in chronic Lyme disease and the nature of the neuropsychological deficits are discussed, as are several central issues in understanding neuropsychological functioning in chronic Lyme disease, such as the impact of chronic illness, response to treatment, and the relationship between neuropsychological performance and depression, fatigue, and neurological indicators of disease.

    Polish population according to the National Census of Population and Housing, which was conducted in 2011, was 38 511.8 thousand. The average life expectancy in Poland is 71.0 years for men and 79.7 years for women. The reason for hospitalization in Poland are primarily cardiovascular disease (18%), tumors (11.4%), digestive diseases (10.6%), respiratory (9.3%), trauma (9.1%), infectious diseases (2.3%) and others (39%). Mortality rates determined on the basis of the analyzes and simulations in different disease groups indicates that the predominant causes of death of Polish citizens are strongly cardiovascular disease and cancer. Respiratory diseases occupy fourth place. World analyses clearly show that the number of deaths in 2030 due to lung diseases will be the fourth (COPD), fifth (pneumonia) and sixth (lung cancer) cause of death. As it turns out, the existence of various pathologies affecting the country's economic status. Respiratory allergies are observed more often, including in approximately 20% of Europeans are symptoms of allergic rhinitis (15-20% severe) and in 5-11% are diagnosed with asthma. Malignant tumors are the second most common causes of death in the group with the highest risk of life for the residents of Polish, particularly for men, is lung cancer, because of which in 2001, 20 570 people died. Incurred costs of the social security system are mainly caused by inflammatory diseases of the respiratory system, which corresponds to the number of days of sick leave, especially in the age group 19-28 years, with a decrease in the age group above 59 years of age. Numbers hospitalized for respiratory diseases according to data from the National Health Fund also clearly indicate the cause of inflammation and cancer, and in the population aged 41-60 years, the need for hospital treatment is multiplied. The data indicate the constant threat of respiratory diseases.

    Along with the wide use of pesticides in the world, the concerns over their health impacts are rapidly growing. There is a huge body of evidence on the relation between exposure to pesticides and elevated rate of chronic diseases such as different types of cancers, diabetes, neurodegenerative disorders like Parkinson, Alzheimer, and amyotrophic lateral sclerosis (ALS), birth defects, and reproductive disorders. There is also circumstantial evidence on the association of exposure to pesticides with some other chronic diseases like respiratory problems, particularly asthma and chronic obstructive pulmonary disease (COPD), cardiovascular disease such as atherosclerosis and coronary artery disease, chronic nephropathies, autoimmune diseases like systemic lupus erythematous and rheumatoid arthritis, chronic fatigue syndrome, and aging. The common feature of chronic disorders is a disturbance in cellular homeostasis, which can be induced via pesticides' primary action like perturbation of ion channels, enzymes, receptors, etc., or can as well be mediated via pathways other than the main mechanism. In this review, we present the highlighted evidence on the association of pesticide's exposure with the incidence of chronic diseases and introduce genetic damages, epigenetic modifications, endocrine disruption, mitochondrial dysfunction, oxidative stress, endoplasmic reticulum stress and unfolded protein response (UPR), impairment of ubiquitin proteasome system, and defective autophagy as the effective mechanisms of action. - Highlights: ► There is a link between exposure to pesticides and incidence of chronic diseases. ► Genotoxicity and proteotoxicity are two main involved mechanisms. ► Epigenetic knowledge may help diagnose the relationships. ► Efficient policies on safe use of pesticides should be set up.

    Full Text Available Pediatric respiratory diseases have been linked to gastroesophageal reflux disease (GERD, but evidence regarding the association and its potential mechanisms continues to accumulate, and important aspects remain to be determined. Evidence for the association in two common pediatric respiratory disorders - infantile apnea and asthma in older children - and difficult clinical issues associated with the diagnosis and treatment of these two disorders are reviewed. The provocative embryological and physiological connections between the upper gastrointestinal tract and the respiratory tract, and recent understanding of the compensatory anatomy and physiology that protect the normal individual from respiratory manifestations of GERD are also explored. Dysfunctions of these protections likely underlie the pathophysiology of these disorders.

    Chronic kidney disease (CKD) is a frequent complication of HIV infection, occurring in 3.5 - 48.5%, and occurs as a complication of HIV infection, other co-morbid disease and infections and as a consequence of therapy of HIV infection and its complications. The classic involvement of the kidney by HIV infection is HIV-associated nephropathy (HIVAN), occurring typically in young adults of African ancestry with advanced HIV disease in association with APOL1 high-risk variants. HIV-immune complex disease is the second most common diagnosis obtained from biopsies of patients with HIV-CKD. CKD is mediated by factors related to the virus, host genetic predisposition and environmental factors. The host response to HIV infection may influence disease phenotype through activation of cytokine pathways. With the introduction of antiretroviral therapy (ART), there has been a decline in the incidence of HIVAN, with an increasing prevalence of focal segmental glomerulosclerosis. Several studies have demonstrated the overall improvement in kidney function when initiating ART for HIV CKD. Progression to end stage kidney disease has been reported to be more likely when high grade proteinuria, severely reduced eGFR, hepatitis B and/C co-infection, diabetes mellitus, extensive glomerulosclerosis, and chronic interstitial fibrosis are present. Improved renal survival is associated with use of renin angiotensin system blockers and viral suppression. Many antiretroviral medications are partially or completely eliminated by the kidney and require dose adjustment in CKD. Certain drug classes, such as the protease inhibitors and the non-nucleoside reverse transcriptase inhibitors, are metabolized by the liver and do not require dose adjustment. HIV-infected patients requiring either hemo- or peritoneal dialysis, who are stable on ART, are achieving survival rates comparable to those of dialysis patients without HIV infection. Kidney transplantation has been performed successfully in HIV

    2015-06-01

    Full Text Available A worldwide epidemic of chronic disease, and complications thereof, is underway, with no sign of abatement. Healthcare costs have increased tremendously, principally because of the need to treat chronic complications of non-communicable diseases including cardiovascular disease, blindness, end-stage renal disease, and amputation of extremities. Current healthcare systems fail to provide an appropriate quality of care to prevent the development of chronic complications without additional healthcare costs. A new paradigm for prevention and treatment of chronic disease and the complications thereof is urgently required. Several clinical studies have clearly shown that frequent communication between physicians and patients, based on electronic data transmission from medical devices, greatly assists in the management of chronic disease. However, for various reasons, these advantages have not translated effectively into real clinical practice. In the present review, we describe current relevant studies, and trends in the use of information technology for chronic disease management. We also discuss limitations and future directions.

    Full Text Available We studied the role of base excess (BE as marker of chronic hypercapnia and survival in patients with chronic obstructive pulmonary disease (COPD and chronic hypercapnic respiratory failure (CHRF. Moreover, it was investigated whether the effects of non-invasive positive pressure ventilation (NPPV on CHRF were reflected in BE and survival. In 240 (160 without exacerbation patients with COPD (mean±SD FEV1 30.7±9.7 %pred; PaCO2 56.9±9.9 mmHg body-mass index (BMI, lung function, respiratory muscle function, blood gases and 6-minute walking distance (6-MWD were assessed prior to initiation of NPPV. In addition, the changes of risk factors 6.3±2.9 months after initiation of NPPV were evaluated. Overall mortality during the follow-up time (26.0±24.5 months was 34.6%. Deaths resulted predominantly from respiratory causes (65.1%; among those, respiratory failure was most frequent (85.2%. Univariate analysis revealed BMI, FEV1, maximal inspiratory pressure (PImax, inspiratory load (P0.1, haemoglobin, 6-MWD, hyperinflation (IC/TLC, RV/TLC, blood gases and BE to be associated (p<0.05 each with prognosis. In multivariate analyses, however, only BMI, RV/TLC and BE turned out to be independent cross-sectional predictors (p<0.05. Kaplan-Meier analyses showed that BE had predictive value particularly in patients with BMI25 kg·m–2, RV/TLC70 % and PaCO257 mmHg. Furthermore, changes of BMI, RV/TLC and BE (p<0.01 were associated with improved prognosis in severe hypercapnic COPD. In patients with COPD and CHRF, BE was a prognostic marker for mortality, that was independent from other factors, particularly PaCO2. In addition, reversal of CHRF was reflected in BE and appeared to have an impact on prognosis.

    A major goal in studying occupational respiratory diseases is to show relationships between occupational exposures and health outcomes. Due to the nature of these diseases, accurate, practical, and objective measurement techniques are needed in field investigations. Pulmonary function tests, such as spirometry, are important objective health outcome measures. However, they reflect the functional changes of the lung, often in relatively late stages, which may be irreversible. Direct monitoring of airways inflammations, in response to occupational exposures, are receiving an increasing attention since they may pick up inflammatory changes before the injury becomes irreversible. Invasive approaches such as bronchoalveolar lavage and bronchial biopsies have been used to assess airways inflammation: but these methods are not practical for use in occupational field investigations. Thus, much work has focused on the development of noninvasive methods for monitoring inflammation in occupational respiratory diseases. The three recent most commonly used noninvasive techniques in occupational respiratory diseases investigations are induced sputum, exhaled breath condensate, and nasal lavage. In this review, we discuss the practical application of these techniques, patents and cytokines measured with them. Since variation of cytokine genes contribute to the inflammatory processes, we briefly discuss the genetic polymorphisms on the expression of occupational respiratory diseases. Details of genetic polymorphism were beyond the focus of this review. Our primary focus was cytokines measured with these three noninvasive techniques in occupational respiratory investigations.

    The pathogenetic mechanisms of anemia in patients with chronic liver disease were observed. Seventeen patients with moderate to advanced hepatic diseases were studied by various methods. Only patients without previous blood loss were included : 14 had cirrhosis, 2 had active chronic hepatitis, and one had inferior vena cava obstruction with associated liver cirrhosis. The followings were the results: 1. The anemia based on red blood cell count, Hb., and Ht. was found in 76.5-78.6% of the patients. 2. Red cell indices indicated that normo-macrocytic and normochromic anemia was present is the majority of the patients. 3. No evidence of megaloblastic anemia was found on the basis of the morphological examinations. 4. Serum iron, TIBC, % saturation and iron content in the bone marrow indicated that iron deficiency anemia was present in about half of the patients. 5. In the view of the erythrocyte dynamics, primary increase in the red cell destruction was ascribed to the cause of the anemia. 6. Decrease in the red cell survival time was not correlated with MCV, % saturation and S.L. ratio. Also, hemoglobin level was not correlated with MCV, % saturation and T{sub 50} Cr. Therefore, multiple causes may be involved in the pathogenesis of the anemia. 7. Anemia as determined by the red cell volume was found in only 60% of the patients. It may be possible that hemodilutional anemia is present.

    Full Text Available Background: in-hospital mortality is a health indicator commonly used as a measure of quality of care. Respiratory diseases are a major cause of deaths in hospitals. Objective: to describe mortality from respiratory diseases at the Dr. Gustavo Aldereguía Lima University General Hospital in Cienfuegos. Methods: a descriptive study of all patients over 18 years old who died from respiratory diseases in the hospital of Cienfuegos from 2010 to 2014 was conducted. The variables analyzed were: age, sex, length of stay, services where the patients died, cause of death, and associated diseases. Results: there was an increase in patients admitted for respiratory diseases and a higher mortality from these diseases (36.2%. Males (54.7%, patients over 75 years (62.5%, and those admitted to internal medicine wards (39.2% predominated. Forty eight point eight percent died within the first 72 hours. The most common respiratory conditions were: pneumonia/bronchopneumonia, chronic obstructive pulmonary disease, and lung cancer, respectively. Sixty three point four percent of the cases developed associated diseases, mainly cardiovascular conditions (26.6%. Conclusions: respiratory diseases are responsible for high in-hospital mortality; the most common causes are pneumonia/bronchopneumonia, mainly in males and in patients older than 75 years.

Indeed, during the past 10 years, the removal of chlorofluorocarbon propellants from industrial and household products intended for the pulmonary route has lead to the developments of new alternative products. Amongst these ones, on one hand, a lot of attention has been focused to improve the bioavailability of marketed drugs intended for respiratory diseases and to develop new concepts for pulmonary administration of drugs and, on the other hand, to use the pulmonary route to administer drugs for systemic diseases. This has led to some marketed products through the last decade. Although the introduction of nanotechnology permitted to step over numerous problems and to improve the bioavailability of drugs, there are, however, unresolved delivery problems to be still addressed. These scientific and industrial innovations and challenges are discussed along this review together with an analysis of the current situation concerning the industrial developments.Keywords: nanotechnology, nanocarriers, nanoparticle, liposome, lung, pulmonary drug delivery, drug targeting, respiratory disease, microemulsion, bioavailability, micelle

    Study covered 426 miners aged 40-54 years with previously diagnosed occupational respiratory diseases due to dust (246 patients with chronic occupational obstructive bronchitis, 98 with anthracosilicosis and 82 with chronic dust nonobstructive bronchitis). 315 (73.9%) examinees out of 426 with lung diseases due to dust demonstrated chronic cor pulnmonale. Considering high share of this complication, the authors used Bayes method to create a method to diagnose predisposition towards chronic cor pulmonale in patients with dust lung diseases through respiratory failure, concomitant coronary heart disease and arterial hypertension, blood groups ABO, MN and P, some structural and functional parameters of heart: myocardium weight index, relative wall thickness index and left ventricle sphericity index, average lung artery pressure. Increasing number of analyzed factors that directly influence chronic cor pulmonale development and selecting additional markers help to improve forecasting of the complication.

    2010 Found a number of significant advances in environmental and occupational respiratory disease. The role of sensitization and the subsequent production of allergic disease have been explored. New allergens and their T- and B-cell epitopes have been characterized. Novel approaches to the diagnosis and evaluation of food allergy have been described. The role of pollutants as they affect respiratory disease and the effects of age extremes on sensitization and asthma have been addressed. Significant advances in the understanding of inflammatory changes in both the upper and lower respiratory systems occurred. Novel therapeutic approaches have been explored, including the development of hypoallergens from improved molecular biology techniques. New effective approaches to asthma therapy have been identified. Exposure reduction through air filtration and novel immunotherapy approaches, such as sublingual therapy, have made significant advances.

  12. Asthma, chronic obstructive pulmonary disease (COPD), and the overlap syndrome.

    Science.gov (United States)

    Nakawah, Mohammad Obadah; Hawkins, Clare; Barbandi, Farouk

    2013-01-01

    Asthma and chronic obstructive pulmonary disease (COPD) are highly prevalent chronic diseases in the general population. Both are characterized by heterogeneous chronic airway inflammation and airway obstruction. In both conditions, chronic inflammation affects the whole respiratory tract, from central to peripheral airways, with different inflammatory cells recruited, different mediators produced, and thus differing responses to therapy. Airway obstruction is typically intermittent and reversible in asthma but is progressive and largely irreversible in COPD. However, there is a considerable pathologic and functional overlap between these 2 heterogeneous disorders, particularly among the elderly, who may have components of both diseases (asthma-COPD overlap syndrome). The definitions for asthma and COPD recommended by current guidelines are useful but limited because they do not illustrate the full spectrum of obstructive airway diseases that is encountered in clinical practice. Defining asthma and COPD as separate entities neglects a considerable proportion of patients with overlapping features and is largely based on expert opinion rather than on the best current evidence. The presence of different phenotypes or components of obstructive airway diseases, therefore, needs to be addressed to individualize and optimize treatment to achieve the best effect with the fewest side effects for the patient. Although specific interventions vary by disease, the treatment goals of obstructive airway diseases are similar and driven primarily by the need to control symptoms, optimize health status, and prevent exacerbations.

    Pulmonary rehabilitation is an evidence-based, multidisciplinary, comprehensive intervention for patients with chronic respiratory diseases who are symptomatic and whose daily living activities are often restricted. Pulmonary rehabilitation programs are designed to improve the physical and emotional condition of people with chronic respiratory disease and to promote long-term adherence to health-enhancing behavior. Exercise training is at the core of pulmonary rehabilitation (PR) programs. The benefits of exercise training include decreased dyspnea, improved health-related quality of life, fewer days of hospitalization, and decreased health-care utilization. To gain PR benefits, patients should be able to complete an exercise training program, preferably with high intensity exercise, and it is likely that these benefits will translate into a change from a pattern of a sedentary lifestyle to a physically active lifestyle. Chronic respiratory patients, namely COPD patients, have a low exercise tolerance due to multiple factors, such as dynamic hyperinflation and peripheral muscle dysfunction. In this article, the authors describe a variety of modalities and strategies to overcome exercise limitations and improve the effects of exercise training.

    Full Text Available The endothelial cell layer is responsible for molecular traffic between the blood and surrounding tissue, and endothelial integrity plays a pivotal role in many aspects of vascular function. Cardiovascular disease (CVD is the main cause of death in patients with chronic kidney disease (CKD and its incidence and severity increase in direct proportion with kidney function decline. Non-traditional risk factors for CVDs, including endothelial dysfunction (ED, are highly prevalent in this population and play an important role in cardiovascular (CV events. ED is the first step in the development of atherosclerosis and its severity has prognostic value for CV events. Several risk markers have been associated with ED. Reduced bioavailability of nitric oxide plays a central role, linking kidney disease to ED, atherosclerosis, and CV events. Inflammation, loss of residual renal function, and insulin resistance are closely related to ED in CKD. ED may be followed by structural damage and remodelling that can precipitate both bleeding and thrombotic events. The endothelium plays a main role in vascular tone and metabolic pathways. ED is the first, yet potentially reversible step in the development of atherosclerosis and its severity has prognostic value for CV events.

    Numerous lines of evidence implicate a role of myeloperoxidase (MPO) in the pathogenesis of cardiovascular disease (CVD). It is a well accepted fact that patients with chronic kidney disease (CKD) are at an increased risk for CVD. MPO is a pro-oxidant enzyme which could be involved in the increased susceptibility of these patients to CVD. Hence, the levels of plasma MPO was determined in healthy controls as well as in patients with CKD [stratified with the level of their kidney failure as CKD stages II-V (end stage renal disease)]. Plasma MPO was assayed by a spectrophotometric method. Serum urea and creatinine were estimated on a clinical chemistry analyzer using standard laboratory procedures. The mean plasma MPO levels were significantly lower with advancing stages of renal failure (P < 0.001). There was a positive correlation between MPO and GFR (r = +0.89, P < 0.001) and a negative correlation with urea (r = -0.85, P < 0.001) and creatinine (r = -0.82, P < 0.001). While an inverse association was observed between plasma MPO and urea in CKD patients, such an association was not observed in control subjects (P = 0.43). In conclusion, the decline in plasma MPO levels may be due to the inhibitory effect of uraemic toxins on the enzyme.

    Full Text Available Abstract Background Environmental pollution is a known risk factor for multiple diseases and furthermore increases rate of hospitalisations. We investigated the correlation between emergency room admissions (ERAs of the general population for respiratory diseases and the environmental pollutant levels in Milan, a metropolis in northern Italy. Methods We collected data from 45770 ERAs for respiratory diseases. A time-stratified case-crossover design was used to investigate the association between air pollution levels and ERAs for acute respiratory conditions. The effects of air pollutants were investigated at lag 0 to lag 5, lag 0–2 and lag 3–5 in both single and multi-pollutant models, adjusted for daily weather variables. Results An increase in ozone (O3 levels at lag 3–5 was associated with a 78% increase in the number of ERAs for asthma, especially during the warm season. Exposure to carbon monoxide (CO proved to be a risk factor for pneumonia at lag 0–2 and in the warm season increased the risk of ERA by 66%. A significant association was found between ERAs for COPD exacerbation and levels of sulphur dioxide (SO2, CO, nitrate dioxide (NO2, and particulate matter (PM10 and PM2.5. The multipollutant model that includes all pollutants showed a significant association between CO (26% and ERA for upper respiratory tract diseases at lag 0–2. For chronic obstructive pulmonary disease (COPD exacerbations, only CO (OR 1.19 showed a significant association. Conclusions Exposure to environmental pollution, even at typical low levels, can increase the risk of ERA for acute respiratory diseases and exacerbation of obstructive lung diseases in the general population.

    Acute kidney injury (AKI),defined as an abrupt increase in the serum creatinine level by at least 0.3 mg/dL,occurs in about 20% of patients hospitalized for decompensating liver cirrhosis.Patients with cirrhosis are susceptible to developing AKI because of the progressive vasodilatory state,reduced effective blood volume and stimulation of vasoconstrictor hormones.The most common causes of AKI in cirrhosis are pre-renal azotemia,hepatorenal syndrome and acute tubular necrosis.Differential diagnosis is based on analysis of circumstances of AKI development,natriuresis,urine osmolality,response to withdrawal of diuretics and volume repletion,and rarely on renal biopsy.Chronic glomeruIonephritis and obstructive uropathy are rare causes of azotemia in cirrhotic patients.AKI is one of the last events in the natural history of chronic liver disease,therefore,such patients should have an expedited referral for liver transplantation.Hepatorenal syndrome (HRS) is initiated by progressive portal hypertension,and may be prematurely triggered by bacterial infections,nonbacterial systemic inflammatory reactions,excessive diuresis,gastrointestinal hemorrhage,diarrhea or nephrotoxic agents.Each type of renal disease has a specific treatment approach ranging from repletion of the vascular system to renal replacement therapy.The treatment of choice in type 1 hepatorenal syndrome is a combination of vasoconstrictor with albumin infusion,which is effective in about 50% of patients.The second-line treatment of HRS involves a transjugular intrahepatic portosystemic shunt,renal vasoprotection or systems of artificial liver support.

    A severe respiratory disease epidemic outbreak correlates with a high demand of specific supplies and specialized personnel to hold it back in a wide region or set of regions; these supplies would be beds, storage areas, hemodynamic monitors, and mechanical ventilators, as well as physicians, respiratory technicians, and specialized nurses. We describe an online cumulative sum based model named Overcrowd-Severe-Respiratory-Disease-Index based on the Modified Overcrowd Index that simultaneously monitors and informs the demand of those supplies and personnel in a healthcare network generating early warnings of severe respiratory disease epidemic outbreaks through the interpretation of such variables. A post hoc historical archive is generated, helping physicians in charge to improve the transit and future allocation of supplies in the entire hospital network during the outbreak. The model was thoroughly verified in a virtual scenario, generating multiple epidemic outbreaks in a 6-year span for a 13-hospital network. When it was superimposed over the H1N1 influenza outbreak census (2008-2010) taken by the National Institute of Medical Sciences and Nutrition Salvador Zubiran in Mexico City, it showed that it is an effective algorithm to notify early warnings of severe respiratory disease epidemic outbreaks with a minimal rate of false alerts.

    Full Text Available Introduction: Chronic obstructive pulmonary disease is characterized by progressive and partially reversible obstruction of pulmonary airflow. Aim: To characterize swallowing in patients with chronic obstructive pulmonary disease and correlate the findings with the degree chronic obstructive pulmonary disease, heart and respiratory rate, oxygen saturation, and smoking. Method: We conducted a prospective cohort study of 19 patients (12 men and 7 women; age range, 50–85 years with confirmed medical diagnosis of chronic obstructive pulmonary disease. This study was performed in 2 stages (clinical evaluation and functional assessment using nasolaryngofibroscopy on the same day. During both stages, vital signs were checked by medical personnel. Results: Clinical evaluation of swallowing in all patients showed the clinical signs of cough. The findings of nasolaryngofibroscopy highlighted subsequent intraoral escape in 5 patients (26.5%. No patient had tracheal aspiration. There was no association of subsequent intraoral escape with degree of chronic obstructive pulmonary disease, heart and respiratory rate, oxygen saturation, or smoking. Conclusion: In patients with chronic obstructive pulmonary disease, there was a prevalence of oral dysphagia upon swallowing and nasolaryngofibroscopy highlighted the finding of subsequent intraoral escape. There was no correlation between intraoral escape and the degree of chronic obstructive pulmonary disease, heart and respiratory rate, oxygen saturation, or smoking.

    Full Text Available MicroRNAs (miRNAs are small non-coding RNA molecules that modulate expression of the majority of genes by inhibiting protein translation. Growing literature has identified functional roles for miRNAs across a broad range of biological processes. As such, miRNAs are recognised as potential disease biomarkers and novel targets for therapies. While several miRNA-targeted therapies are currently in clinical trials (e.g. for the treatment of hepatitis C virus infection and cancer, no therapies have targeted miRNAs in respiratory diseases in the clinic. In this mini-review, we review the current knowledge on miRNA expression and function in respiratory diseases, intervention strategies to target miRNA function and considerations specific to respiratory diseases. Altered miRNA expression profiles have been reported in a number of respiratory diseases, including asthma, chronic obstructive pulmonary disease, cystic fibrosis and idiopathic pulmonary fibrosis. These include alterations in isolated lung tissue, as well as sputum, bronchoalveolar lavage fluids and peripheral blood or serum. The observed alterations in easily accessible body fluids (e.g. serum have been proposed as new biomarkers that may inform disease diagnosis and patient management. In a subset of studies, miRNA-targeted interventions also improved disease outcomes, indicating functional roles for altered miRNA expression in disease pathogenesis. In fact, direct administration of miRNA-targeting molecules to the lung has yielded promising results in a number of animal models. The ability to directly administer compounds to the lung holds considerable promise and may limit potential off-target effects and side effects caused by the systemic administration required to treat other diseases.

    Host-microorganism interactions shape local cell functionality, immune responses, and can influence disease development. Evidence indicates that the impact of host-microbe interactions reaches far beyond the local environment, thus influencing responses in peripheral tissues. There is a vital cross-talk between the mucosal tissues of our body, as exemplified by intestinal complications during respiratory disease and vice versa. Although, mechanistically, this phenomenon remains poorly defined, the existence of the gut-lung axis and its implications in both health and disease could be profoundly important for both disease etiology and treatment. In this review, we highlight how changes in the intestinal microenvironment, with a particular focus on the intestinal microbiota, impact upon respiratory disease.

    Detection of early chronic obstructive pulmonary disease (COPD) in patients presenting with respiratory symptoms is recommended; however, diagnosing COPD is difficult because a single gold standard is not available. The aim of this article is to review and interpret the existing evidence, theories and consensus on the individual parts of the diagnostic work-up for COPD. Relevant articles are discussed under the subheadings: history taking, physical examination, spirometry and additional lung function assessment. Wheezing, cough, phlegm and breathlessness on exertion are suggestive signs for COPD. The diagnostic value of the physical examination is limited, except for auscultated pulmonary wheezing or reduced breath sounds, increasing the probability of COPD. Spirometric airflow obstruction after bronchodilation, defined as a lowered ratio of the forced volume in one second to the forced vital capacity (FEV1/FVC ratio), is a prerequisite, but can only confirm COPD in combination with suggestive symptoms. Different thresholds are being recommended to define low FEV1/FVC, including a fixed threshold, and one varying with gender and age; however, the way physicians interpret these thresholds in their assessment is not well known. Body plethysmography allows a more complete assessment of pulmonary function, providing results on the total lung capacity and the residual volume and is indicated when conventional spirometry results are inconclusive. Chest radiography has no diagnostic value for COPD but is useful to exclude alternative diagnoses such as heart failure or lung cancer. Extensive history taking is of key importance in diagnosing COPD.

  11. End-of-life decision making in respiratory failure. The therapeutic choices in chronic respiratory failure in a 7-item questionnaire

    Dagmar Elfriede Rinnenburger

    2012-01-01

    Full Text Available INTRODUCTION: The transition from paternalistic medicine to a healthcare culture centred on the patient's decision making autonomy presents problems of communication and understanding. Chronic respiratory failure challenges patients, their families and caregivers with important choices, such as invasive and non-invasive mechanical ventilation and tracheostomy, which, especially in the case of neuromuscular diseases, can significantly postpone the end of life. MATERIAL AND METHODS: A 7-item questionnaire was administered to 100 patients with advanced COPD, neuromuscular diseases and pulmonary fibrosis, all of them on oxygen therapy and receiving day-hospital treatment for respiratory failure. The objective was to find out whether or not patients, if faced with a deterioration of their health condition, would want to take part in the decision making process and, if so, how and with whom. RESULTS. Results showed that: 90% of patients wanted to be interviewed, 10% preferred not to be interviewed, 82% wanted to be regularly updated on their clinical situation, 75% wanted to be intubated, if necessary, and 56% would also agree to have a tracheostomy. These choices have been confirmed one year later, with 93% of respondents accepting the questionnaire and considering it useful. CONCLUSIONS: It is possible to conclude that a simple questionnaire can be a useful tool contributing to therapeutic decision making in respiratory failure.

  12. Common lung conditions: chronic obstructive pulmonary disease.

    Delzell, John E

    2013-06-01

    The etiology of chronic obstructive pulmonary disease (COPD) is chronic lung inflammation. In the United States, this inflammation most commonly is caused by smoking. COPD is diagnosed when an at-risk patient presents with respiratory symptoms and has irreversible airway obstruction indicated by a forced expiratory volume in 1 second/forced vital capacity ratio of less than 0.7. Management goals for COPD include smoking cessation, symptom reduction, exacerbation reduction, hospitalization avoidance, and improvement of quality of life. Stable patients with COPD who remain symptomatic despite using short-acting bronchodilators should start inhaled maintenance drugs to reduce symptoms and exacerbations, avoid hospitalizations, and improve quality of life. A long-acting anticholinergic or a long-acting beta2-agonist (LABA) can be used for initial therapy; these drugs have fewer adverse effects than inhaled corticosteroids (ICS). If patients remain symptomatic despite monotherapy, dual therapy with a long-acting anticholinergic and a LABA, or a LABA and an ICS, may be beneficial. Triple therapy (ie, a long-acting anticholinergic, a LABA, and an ICS) also is used, but it is unclear if triple therapy is superior to dual therapy. Roflumilast, an oral selective inhibitor of phosphodiesterase 4, is used to manage moderate to severe COPD. Continuous oxygen therapy is indicated for patients with COPD who have severe hypoxemia (ie, PaO2 less than 55 mm Hg or an oxygen saturation less than 88% on room air). Nonpharmacologic strategies also are useful to improve patient outcomes. Pulmonary rehabilitation improves dyspnea and quality of life. Pulmonary rehabilitation after an acute exacerbation reduces hospitalizations and mortality, and improves quality of life and exercise capacity. Smoking cessation is the most effective management strategy for reducing morbidity and mortality in patients with COPD. Lung volume reduction surgery, bullectomy, and lung transplantation are

    Probiotics are the focus of a thorough investigation as a natural biotreatment due to their various health-promoting effects and inherent ability to fight specific diseases including chronic kidney disease (CKD). Indeed, intestinal microbiota has recently emerged as an important player in the progression and complications of CKD. Because many of the multifactorial physiological functions of probiotics are highly strain specific, preselection of appropriate probiotic strains based on their expression of functional biomarkers is critical. The interest in developing new research initiatives on probiotics in CKD have increased over the last decade with the goal of fully exploring their therapeutic potentials. The efficacy of probiotics to decrease uremic toxin production and to improve renal function has been investigated in in vitro models and in various animal and human CKD studies. However to date, the quality of intervention trials investigating this novel CKD therapy is still lacking. This review outlines potential mechanisms of action and efficacy of probiotics as a new CKD management tool, with a particular emphasis on uremic toxin production and inflammation.

    Full Text Available Pathogens causing bovine respiratory tract disease in Finland were investigated. Eighteen cattle herds with bovine respiratory disease were included. Five diseased calves from each farm were chosen for closer examination and tracheobronchial lavage. Blood samples were taken from the calves at the time of the investigation and from 86 calves 3–4 weeks later. In addition, 6–10 blood samples from animals of different ages were collected from each herd, resulting in 169 samples. Serum samples were tested for antibodies to bovine parainfluenza virus-3 (PIV-3, bovine respiratory syncytial virus (BRSV, bovine coronavirus (BCV, bovine adenovirus-3 (BAV-3 and bovine adenovirus-7 (BAV-7. About one third of the samples were also tested for antibodies to bovine virus diarrhoea virus (BVDV with negative results. Bacteria were cultured from lavage fluid and in vitro susceptibility to selected antimicrobials was tested. According to serological findings, PIV-3, BAV-7, BAV-3, BCV and BRSV are common pathogens in Finnish cattle with respiratory problems. A titre rise especially for BAV-7 and BAV-3, the dual growth of Mycoplasma dispar and Pasteurella multocida, were typical findings in diseased calves. Pasteurella sp. strains showed no resistance to tested antimicrobials. Mycoplasma bovis and Mannheimia haemolytica were not found.

    Full Text Available This study was conducted in order to map European research in chronic respiratory diseases (CRDs. It was intended to assist the European Commission and other research funders to identify gaps and overlaps in their portfolios, and to suggest ways in which they could improve the effectiveness of their support and increase the impact of the research on patient care and on the reduction of the incidence of the CRDs. Articles and reviews were identified in the Web of Science on research in six non-communicable respiratory diseases that were published in 2002-13 from 31 European countries. They represented only 0.8% of biomedical research output but these diseases accounted for 4.7% of the European disease burden, as measured by Disability-Adjusted Life Years (DALYs, so the sub-field is seriously under-researched. Europe is prominent in the sub-field and published 56% of the world total, with the UK the most productive and publishing more than France and Italy, the next two countries, combined. Asthma and Chronic Obstructive Pulmonary Disease (COPD were the diseases with the most publications and the highest citation rates. They also received the most funding, with around two acknowledgments per paper (in 2009-13, whereas cystic fibrosis and emphysema averaged only one. Just over 37% of papers had no specific funding and depended on institutional support from universities and hospitals.

  3. Hedgehogs and sugar gliders: respiratory anatomy, physiology, and disease.

    Johnson, Dan H

    2011-05-01

    This article discusses the respiratory anatomy, physiology, and disease of African pygmy hedgehogs (Atelerix albiventris) and sugar gliders (Petaurus breviceps), two species commonly seen in exotic animal practice. Where appropriate, information from closely related species is mentioned because cross-susceptibility is likely and because these additional species may also be encountered in practice. Other body systems and processes are discussed insofar as they relate to or affect respiratory function. Although some topics, such as special senses, hibernation, or vocalization, may seem out of place, in each case the information relates back to respiration in some important way.

    Full Text Available Objectives. Mount Sakurajima in Japan is one of the most active volcanoes in the world. This work was conducted to examine the effect of volcanic ash on the chronic respiratory disease mortality in the vicinity of Mt. Sakurajima. Methods. The present work examined the standardized mortality ratios (SMRs of respiratory diseases during the period 1968–2002 in Sakurajima town and Tarumizu city, where ashfall from the volcano recorded more than 10.000 g/m2/yr on average in the 1980s. Results. The SMR of lung cancer in the Sakurajima-Tarumizu area was 1.61 (95% CI = 1.44–1.78 for men and 1.67 (95% CI = 1.39–1.95 for women while it was nearly equal to one in Kanoya city, which neighbors Tarumizu city but located at the further position from Mt. Sakurajima, and therefore has much smaller amounts of ashfall. Sakurajima-Tarumizu area had elevated SMRs for COPDs and acute respiratory diseases while Kanoya did not. Conclusions. Cristobalite is the most likely cause of the increased deaths from those chronic respiratory diseases since smoking is unlikely to explain the increased mortality of respiratory diseases among women since the proportion of smokers in Japanese women is less than 20%, and SPM levels in the Sakurajima-Tarumizu area were not high. Further studies seem warranted.

    Jacobsen, Gitte; Schaumburg, Inger; Sigsgaard, Torben; Schlunssen, Vivi

    2010-01-01

    This paper reviews the literature on associations between dry wood dust exposure and non-malignant respiratory diseases. Criteria for inclusion are epidemiological studies in English language journals with an internal or external control group describing relationships between dry wood dust exposure and respiratory diseases or symptoms. Papers took into consideration smoking and when dealing with lung function age. A total of 37 papers forms the basis of this review. The results support an association between dry wood dust exposure and asthma, asthma symptoms, coughing, bronchitis, and acute and chronic impairment of lung function. In addition, an association between wood dust exposure and rhino-conjunctivitis is seen across the studies. Apart from plicatic acid in western red cedar wood, no causal agent has consistently been disclosed. Type 1 allergy is not suspected to be a major cause of wood dust induced asthma.

    Full Text Available Theodore G Liou, Sanjeev M Raman, Barbara C CahillDivision of Respiratory, Critical Care and Occupational Pulmonary Medicine, Department of Medicine, School of Medicine, University of Utah, Salt Lake City, Utah, USAAbstract: Patients with end-stage chronic obstructive pulmonary disease (COPD comprise the largest single lung disease group undergoing transplantation. Selection of appropriate candidates requires consideration of specific clinical characteristics, prognosis in the absence of transplantation, and likely outcome of transplantation. Increased availability of alternatives to transplantation for end-stage patients and the many efforts to increase the supply of donor organs have complicated decision making for selecting transplant candidates. Many years of technical and clinical refinements in lung transplantation methods have improved survival and quality of life outcomes. Further advances will probably come from improved selection methods for the procedure. Because no prospective trial has been performed, and because of confounding and informative censoring bias inherent in the transplant selection process in studies of the existing experience, the survival effect of lung transplant in COPD patients remains undefined. There is a lack of conclusive data on the impact of lung transplantation on quality of life. For some patients with end-stage COPD, lung transplantation remains the only option for further treatment with a hope of improved survival and quality of life. A prospective trial of lung transplantation is needed to provide better guidance concerning survival benefit, resource utilization, and quality of life effects for patients with COPD.Keywords: outcomes, emphysema, COPD, alpha-1-antitrypsin deficiency, survival, single lung transplant, bilateral sequential single lung transplant, lung volume reduction, referral, guidelines, health related quality of life

  9. Chronic respiratory aeroallergen exposure in mice induces epithelial-mesenchymal transition in the large airways.

    Directory of Open Access Journals (Sweden)

    Jill R Johnson

    Full Text Available Chronic allergic asthma is characterized by Th2-polarized inflammation and leads to airway remodeling and fibrosis but the mechanisms involved are not clear. To determine whether epithelial-mesenchymal transition contributes to airway remodeling in asthma, we induced allergic airway inflammation in mice by intranasal administration of house dust mite (HDM extract for up to 15 consecutive weeks. We report that respiratory exposure to HDM led to significant airway inflammation and thickening of the smooth muscle layer in the wall of the large airways. Transforming growth factor beta-1 (TGF-β1 levels increased in mouse airways while epithelial cells lost expression of E-cadherin and occludin and gained expression of the mesenchymal proteins vimentin, alpha-smooth muscle actin (α-SMA and pro-collagen I. We also observed increased expression and nuclear translocation of Snail1, a transcriptional repressor of E-cadherin and a potent inducer of EMT, in the airway epithelial cells of HDM-exposed mice. Furthermore, fate-mapping studies revealed migration of airway epithelial cells into the sub-epithelial regions of the airway wall. These results show the contribution of EMT to airway remodeling in chronic asthma-like inflammation and suggest that Th2-polarized airway inflammation can trigger invasion of epithelial cells into the subepithelial regions of the airway wall where they contribute to fibrosis, demonstrating a previously unknown plasticity of the airway epithelium in allergic airway disease.

    2008-06-01

    This review of key articles appearing in the Journal in 2008 represents significant advances in the understanding of the interrelationships between the environment and allergic respiratory diseases. New allergens have been identified and characterized. Improvements in diagnostic techniques and methods to assess environmental allergen exposure have been developed. The novel therapeutics and refinements of allergen avoidance approaches will improve patient care. A fuller appreciation of the complexities of environmental factors in allergic diseases can lead to better preventative measures. Lastly, the increasingly important role of pollutants on inflammatory processes is evolving. The articles discussed will add to our increasing knowledge base and advance the ability to more effectively treat patients with allergic respiratory diseases and expand research opportunities.

    @@ The severe acute respiratory syndrome (SARS) that emerged 2002-2003 and apparently again 2004 (reported by the news media on December 27, 2003) as the first confirmed case by the World Health Organization (WHO)1,2 raised awareness of emerging infectious diseases.3 Every year there are both new and old infectious diseases emerging as potential pandemic agents.4-6 However, few of these diseases receive the public attention and concern expressed as occurred during the emergence of SARS. Much of this concern was a result of the rapid spread of the novel coronavirus (CoV) to different regions of the world and its high infectivity, especially for health care workers (HCW).3 In many ways, the high percent of HCW infected is a warning of the potential hazards of old and emerging infectious diseases.6 However, SARS was not the only disease (e.g. Monkeypox) that emerged in 2003,3 rather it received the greatest attention.

    Full Text Available Abstract Background Health-related quality of life (HRQL is considered as an important outcome parameter in patients with chronic diseases. This study aimed to assess the role of disease-specific HRQL for long-term survival in patients of different diagnoses with chronic hypercapnic respiratory failure (CHRF. Methods In a cohort of 231 stable patients (chronic obstructive pulmonary disease (COPD, n = 98; non-COPD (obesity-hypoventilation syndrome, restrictive disorders, neuromuscular disorders, n = 133 with CHRF and current home mechanical ventilation (HMV, HRQL was assessed by the disease-specific Severe Respiratory Insufficiency (SRI questionnaire and its prognostic value was prospectively evaluated during a follow-up of 2–4 years, using univariate and multivariate regression analysis. Results HRQL was more impaired in COPD (mean ± SD SRI-summary score (SRI-SS 52.5 ± 15.6 than non-COPD patients (67.6 ± 16.4; p 1 turned out to be independent predictors (p Conclusion In patients with CHRF and HMV, the disease-specific SRI was an overall predictor of long-term survival in addition to established risk factors. However, the SRI predominantly beared information regarding long-term survival in non-COPD patients, while in COPD patients objective measures of the disease state were superior. This on one hand highlights the significance of HRQL in the long-term course of patients with CHRF, on the other hand it suggests that the predictive value of HRQL depends on the underlying disease.

    Vaccines and antibiotics are still relied upon as the standard methods of bovine respiratory disease (BRD) prevention, control, and therapy. Success in building disease resistance begins with genetic selection and continues with colostrum management and reducing pathogen exposure. Purchasing single-source cattle with a history of pre- and post-weaning procedures will minimize pathogen exposure and enhance immunity. Using cattle-handling techniques and facilities that promote low stress will allow host immune defenses to remain effective against bacterial and viral colonization. Lastly, controlling BRD must be managed through a comprehensive herd health immunization and management program that effectively addresses disease challenges common to the operation.

    The aetiology of chronic idiopathic intestinal inflammation is unknown. It is characterized by a diffuse infiltration with inflammatory cells into the intestinal mucosa and sometimes submucosa. Cats with chronic intermittent vomiting and diarrhoea, later on accompanied by anorexia and weight loss, are presented. Definitive diagnosis can be obtained by intestinal biopsy only. An immune pathogenesis is suspected, which is supported by the fact, that chronic inflammatory bowel disease responds to steroid therapy.

    HIV/AIDS has always been one of the most thoroughly global of diseases. In the era of widely available anti-retroviral therapy (ART), it is also commonly recognised as a chronic disease that can be successfully managed on a long-term basis. This article examines the chronic character of the HIV/AIDS pandemic and highlights some of the changes we might expect to see at the global level as HIV is increasingly normalised as "just another chronic disease". The article also addresses the use of this language of chronicity to interpret the HIV/AIDS pandemic and calls into question some of the consequences of an uncritical acceptance of concepts of chronicity.

  1. Is acute recurrent pancreatitis a chronic disease?

    2008-01-01

    Whether acute recurrent pancreaUtis is a chronic disease is still debated and a consensus is not still reached as demonstrated by differences in the classification of acute recurrent pancreatitis.There is major evidence for considering alcoholic pancreatitis as a chronic disease ab initio while chronic pancreatitis lesions detectable in biliary acute recurrent pancreatitis (ARP) seem a casual association.Cystic fibrosis transmembrane con ductance regulator (CFTR) gene mutation,hereditary and obstructive pancreatitis seem an acute disease that progress to chronic pancreatitis,likely as a consequence of the activation and proliferation of pancreatic stellate cells that produce and activate collagen and therefore fibrosis.From the diagnostic point of view,in patients with acute recurrent pancreatitis Endoscopic ultrasound (EUS) seems the more reliable technique for an accurate evaluation and follow-up of some ductal and parenchymal abnormalities suspected for early chronic pancreatitis.

    2016-01-01

    Aspirin-exacerbated respiratory disease (AERD) is a late onset condition characterized by the Samter triad (aspirin sensitivity [as well as sensitivity to any nonselective cyclooxygenase inhibitor], nasal polyps, asthma) and additional features, including eosinophilic chronic rhinosinusitis, hypereosinophilia, anosmia, frequent absence of atopy, and, intolerance to ingestion of red wine and other alcoholic beverages. The diagnosis is rare, and, because of this, it is also often missed by physicians. However, it is highly overexpressed in patients with severe asthma (and severe chronic rhinosinusitis with nasal polyps), which makes its recognition essential. For this review, we considered mechanisms involved in the pathogenesis of this disease and discussed the clinical symptoms of AERD. We also discussed the role of aspirin desensitization in the treatment of AERD. Also, we considered medications (e.g, leukotriene modifiers) and surgical interventions that have a role in the treatment of AERD.

    2006-02-01

    Female sexual dysfunction (FSD) is a multifactorial set of conditions associated with multiple anatomical, physiological, biological, medical and psychological factors that can have major impact on self-esteem, quality of life, mood and relationships. Studies indicate that FSD is commonly seen in women who report a low level of satisfaction with partner relationship and in women with male partners who have erectile dysfunction. This complexity of FSD is augmented by the presence of chronic disease. Negative sexual effects are widely reported in studies of women with chronic diseases (such as metabolic syndrome, diabetes mellitus, chronic kidney disease, cancer, spinal cord injury, lupus, rheumatic diseases, Parkinson's disease, fibromyalgia and chronic pain) as compared to a general healthy female population. Physical problems, emotional problems and partnership difficulties arising from disease-related stress contribute to less active and less enjoyable sex life. Chronic pain, fatigue, low self-esteem as well as use of medications might reduce sexual function. These effects of chronic diseases on female sexual function still remain largely unstudied. The study by Manor and Zohar published in this issue of Harefuah draws our attention to the sexual dysfunction of women with breast cancer and examines their needs for information regarding their sexual function. In the absence of definite treatment evidence, psychological counseling, improved vaginal lubrication, low dose of hormonal therapy can be used to relieve FSD. Physicians must consider integrating diagnosis of their female patients' sexual needs and dysfunction, especially women with chronic diseases. Patients' education and counseling may contribute to a better quality of life in spite of their chronic disease.

    Ioannis Vogiatzis

    2012-01-01

    Full Text Available In chronic lung diseases physical activity limitation is multifactorial involving respiratory, hemodynamic, and peripheral muscle abnormalities. The mechanisms of limitation discussed in this paper relate to (i the imbalance between ventilatory capacity and demand, (ii the imbalance between energy demand and supply to working respiratory and peripheral muscles, and (iii the factors that induce peripheral muscle dysfunction. In practice, intolerable exertional symptoms (i.e., dyspnea and/or leg discomfort are the main symptoms that limit physical performance in patients with chronic lung diseases. Furthermore, the reduced capacity for physical work and the adoption of a sedentary lifestyle, in an attempt to avoid breathlessness upon physical exertion, cause profound muscle deconditioning which in turn leads to disability and loss of functional independence. Accordingly, physical inactivity is an important component of worsening the patients’ quality of life and contributes importantly to poor prognosis. Identifying the factors which prevent a patient with lung disease to easily carry out activities of daily living provides a unique as well as important perspective for the choice of the appropriate therapeutic strategy.

    Full Text Available Introduction. Nutritional abnormalities have one of the most important systematic effects on chronic obstructive pulmonary disease (COPD. A relationship between COPD and obesity has been observed and recognized. In COPD patients, beside changes in the total body weight, changes in body composition are also possible with the loss of fat-free mass (FFM. Objective. This study was undertaken to evaluate the impact of obesity and the change of body composition on the pulmonary function, dyspnoea level and the quality of life in COPD patients. Methods. Seventy-nine patients in the stable state of COPD were evaluated. Pulmonary function and arterial blood gas analysis were assessed. Nutritional status was analyzed according to Body Mass Index (BMI. Body composition was evaluated by using anthropometric measurement by fat free mass index (FFMI. Quality of life was assessed using the St. George Respiratory Questionnaire (SGRQ. The Visual Analogue Scale (VAS was used to evaluate dyspnoea. Results. The highest prevalence of obesity (50.0% was found in patients with mild COPD, while the lowest prevalence was detected in very severe COPD patients (10.0%. The loss of FFM occurred in 22.2% patients with normal body weight and in 9.0% of overweight COPD patients. The quality of life was lower in obese patients compared to other COPD patients. A higher dyspnoea level was also present in obese patients. The lowest airflow obstruction was in obese patients (p=0.023. We found a significant positive correlation between forced expiratory volume in the first second (FEV1% and BMI (r=0.326, p=0.003, FEV1% and FFMI (r=0.321, p=0.004. Conclusion. The highest prevalence of obesity was in patients with mild COPD. Obese patients with COPD had the lowest level of airflow obstruction, higher dyspnoea level and lower quality of life in comparison to other COPD patients.

    Lyme disease is a tick-borne illness endemic to Minnesota that can have potentially severe complications. As the incidence of Lyme disease continues to increase, it is important for physicians in Minnesota to become familiar with its clinical aspects, including the concept of "chronic Lyme disease." Chronic Lyme disease is a misnomer that is often applied to patients with nonspecific presentations who may or may not have a history of infection with Borrelia burgdorferi, the agent that causes Lyme disease. When a patient does present with persistent nonspecific symptoms attributed to chronic Lyme disease, clinicians should ascertain the presence of objective manifestations, obtain laboratory results, and get a history of tick exposure. If active infection with B. burgdorferi is unlikely, they should avoid prescribing empiric antibiotic therapy and instead thoroughly evaluate the patient for other possible causes of the complaints and recommend appropriate care.

  15. Studying human respiratory disease in animals--role of induced and naturally occurring models.

    2016-01-01

    Respiratory disorders like asthma, emphysema, and pulmonary fibrosis affect millions of Americans and many more worldwide. Despite advancements in medical research that have led to improved understanding of the pathophysiology of these conditions and sometimes to new therapeutic interventions, these disorders are for the most part chronic and progressive; current interventions are not curative and do not halt disease progression. A major obstacle to further advancements relates to the absence of animal models that exactly resemble the human condition, which delays the elucidation of relevant mechanisms of action, the unveiling of biomarkers of disease progression, and identification of new targets for intervention in patients. There are currently many induced animal models of human respiratory disease available for study, and even though they mimic features of human disease, discoveries in these models have not always translated into safe and effective treatments in humans. A major obstacle relates to the genetic, anatomical, and functional variations amongst species, which represents the major challenge to overcome when searching for appropriate models of respiratory disease. Nevertheless, rodents, in particular mice, have become the most common species used for experimentation, due to their relatively low cost, size, and adequate understanding of murine genetics, among other advantages. Less well known is the fact that domestic animals also suffer from respiratory illnesses similar to those found in humans. Asthma, bronchitis, pneumonia, and pulmonary fibrosis are among the many disorders occurring naturally in dogs, cats, and horses, among other species. These models might better resemble the human condition and are emphasized here, but further investigations are needed to determine their relevance.

    Medical treatment for patients with stable chronic obstructive pulmonary disease (COPD) has evolved significantly over the past 2 decades. Current World Health Organization recommendations suggest a stepwise approach to therapy depending upon disease severity. As-needed use of short-acting bronchodilators is recommended for patients with mild disease. Scheduled dosing of bronchodilators is recommended for patients with more advanced disease. Inhaled beta-agonists and anti-cholinergic agents in combination have proved to be more effective than either agent alone. Long-acting preparations are associated with better disease control and have not been associated with tachyphylaxis. Inhaled corticosteroids are useful for reducing the frequency of exacerbations in patients who experience one or more episodes per year. Oxygen therapy is clearly beneficial in patients with advanced COPD and chronic respiratory failure, and its potential benefits in less severe disease are currently being studied. Pulmonary rehabilitation benefits patients with mild-to-severe disease, although the greatest benefits have been demonstrated in those with moderate COPD. New ultra-long-acting inhaled bronchodilators, phosphodiesterase inhibitors, protease inhibitors, and retinoids intended to promote tissue regeneration are currently being evaluated in clinical trials as future therapeutic agents.

  18. Occupational respiratory diseases in the South African mining industry

    Directory of Open Access Journals (Sweden)

    Gill Nelson

    2013-01-01

    Full Text Available Background: Crystalline silica and asbestos are common minerals that occur throughout South Africa, exposure to either causes respiratory disease. Most studies on silicosis in South Africa have been cross-sectional and long-term trends have not been reported. Although much research has been conducted on the health effects of silica dust and asbestos fibre in the gold-mining and asbestos-mining sectors, little is known about their health effects in other mining sectors. Objective: The aims of this thesis were to describe silicosis trends in gold miners over three decades, and to explore the potential for diamond mine workers to develop asbestos-related diseases and platinum mine workers to develop silicosis. Methods: Mine workers for the three sub-studies were identified from a mine worker autopsy database at the National Institute for Occupational Health. Results: From 1975 to 2007, the proportions of white and black gold mine workers with silicosis increased from 18 to 22% and from 3 to 32% respectively. Cases of diamond and platinum mine workers with asbestos-related diseases and silicosis, respectively, were also identified. Conclusion: The trends in silicosis in gold miners at autopsy clearly demonstrate the failure of the gold mines to adequately control dust and prevent occupational respiratory disease. The two case series of diamond and platinum mine workers contribute to the evidence for the risk of asbestos-related diseases in diamond mine workers and silicosis in platinum mine workers, respectively. The absence of reliable environmental dust measurements and incomplete work history records impedes occupational health research in South Africa because it is difficult to identify and/or validate sources of dust exposure that may be associated with occupational respiratory disease.

    Asthma and chronic obstructive pulmonary disease (COPD) are characterized in their pathogenesis by chronic inflammation in the airways. Phosphoinositide 3-kinase δ (PI3Kδ), a lipid kinase expressed predominantly in leukocytes, is thought to hold much promise as a therapeutic target for such inflammatory conditions. Of particular interest for the treatment of severe respiratory disease is the observation that inhibition of PI3Kδ may restore steroid effectiveness under conditions of oxidative stress. PI3Kδ inhibition may also prevent recruitment of inflammatory cells, including T lymphocytes and neutrophils, as well as the release of proinflammatory mediators, such as cytokines, chemokines, reactive oxygen species, and proteolytic enzymes. In addition, targeting the PI3Kδ pathway could reduce the incidence of pathogen-induced exacerbations by improving macrophage-mediated bacterial clearance. In this review, we discuss the potential and highlight the unknowns of targeting PI3Kδ for the treatment of respiratory disease, focusing on recent developments in the role of the PI3Kδ pathway in inflammatory cell types believed to be critical to the pathogenesis of COPD.

    2014-05-01

    Sleep disturbances (SD) are a frequent finding in patients with asthma and chronic obstructive pulmonary disease (COPD) and have a negative impact on quality of life and the clinical course of the disease. The causes of SD are multiple and include for example respiratory symptoms and comorbidities. On the other hand sleep goes along with multiple physiological changes in respiration, so that sleep itself interacts with asthma and COPD. This interaction favors respiratory symptoms and may lead to hypoxemia and hypercapnia. A further complication of the respiratory situation and the clinical course can be found in asthma and COPD patients with coexisting obstructive sleep apnea syndrome (OSAS). Due to the heterogeneity of SD in asthma and COPD, a detailed patient survey is the most important diagnostical tool. Based on the survey further technical examinations should be considered. Treatment strategies for the reduction of SD in asthma and COPD include an optimized medication and treatment of comorbidities. If indicated oxygen therapy, positive pressure breathing and pulmonary rehabilitation can contribute.

    The contribution of the polymorphic markers of cytochrome P450 genes to respiratory diseases caused by smoking and occupational factors has been assessed. For this purpose, PCR-RFLP analysis of the CYP1B1 (rs1056836, 4326C > G), CYP2F1 (rs11399890, c.14_15insC), CYP2J2 (rs890293, -76G > T), and CYP2S1 (rs34971233, 13106C > T and rs338583, 13255A > G) gene polymorphisms has been performed. The analysis has shown that the polymorphic variants of the CYP1B1 (rs1056836, 4326C > G) and CYP2F1 (rs11399890, c. 14_15insC) genes may contribute to the development of occupational chronic bronchitis. The proportion of CYP1B1* 1*3 heterozygotes in the group of patients with occupational chronic bronchitis is considerably greater than in the group of healthy workers (69.16% versus 53.29%; chi2 = 5.94, P = 0.02, P(cor) = 0.04, OR = 1.97, the 95% CI is 1.13-3.42). Patients with occupational chronic bronchitis and healthy workers significantly differed from each other in the frequency distribution of the genotypes ofthe CYP2F1 (rs11399890, c.14_15insC) polymorphic marker (chi2 = 6.18, d.f = 2, P = 0.05). The frequency of the wild type/ins heterozygous genotype for the CYP2F1 gene is higher in healthy workers (36.08%) than in patients (22.22%) (chi2 = 5.48, P = 0.02, P(cor) = 0.04, OR = 0.51, the 95% CI is 0.28-0.90). No association has been found between the CYP2J2 (rs890293, -76G > T) or CYP2S1 (rs34971233, 13106C > T, P466L and rs338583, 13255A > G) gene polymorphisms and respiratory diseases.

    Full Text Available Abstract. We studied cytokine profile in blood and exhaled breath condensate (EBC in patients with chronic obstructive pulmonary disease (COPD being in remission state. It is shown that pro- and anti-inflammatory cytokine contents depended on the disease severity, both in whole blood and EBC of the COPD patients. We have revealed an increase in TNFα, s-TNFα RI, TGF-β1 and bFGF in EBC of patients with COPD manifestations, thus being indicative for progression of metabolic changes in lung tissue, and advanced stage of respiratory functional disturbances. Cytokine profile abnormalities in COPD patients resulting, in part, from systemic and local disorders of cellular immunity, represent a major pathogenetic mechanism determining the disease progression.

    Chronic and recurrent respiratory tract disorders are a frequent problem in general practice. The purpose of the study was to investigate the role of hypersensitivity to house dust mites in respiratory tract diseases in general practice patients. We tried to assess the influence of determined risk factors exposure on development of respiratory tract allergy. Patients from family practitioners surgeries with chronic or recurrent respiratory tract symptoms who had no diagnosis of allergy were recruited to the study (n = 89). All patients responded to a questionnaire focused on history of symptoms, atopic conditions in family and exposure to determined environmental factors like dwelling conditions, obstetrician history, diet in the first year of life. All patients underwent skin prick test with common inhalant allergens. Families of the patients were asked to participate in the study. Families who agreed to take part also responded to the questionnaire and underwent skin tests. In patients and their families blood samples were taken to determine total IgE and specific IgE antibodies to mites allergens. Dust samples were collected by vacuuming of patients' bedroom carpets and mattresses to determine house dust mites allergens concentration. Data on 30 complete patients family sets of their brotherhood, mother and father were collected. Total and specific serum IgE antibodies were determined by disc enzyme-immunoassay (Analco). Mites allergens concentration in dust was measured by simple Acarex strip test (Nexter). The results of the assays (positive skin tests and/or elevated levels of specific IgE) showed allergy to house dust mites in 24 of 89 study patients from general practitioners surgeries (27%). The prevalence of chronic rhinitis, recurrent bronchitis, chronic or recurrent cough, wheezing, dyspnoea was higher in allergic than in nonallergic subjects. Patients with the diagnosis of allergy to house dust mites had usually worse dwelling conditions. Especially

    Exosomes are nanosized vesicles released from every cell in the body including those in the respiratory tract and lungs. They are found in most body fluids and contain a number of different biomolecules including proteins, lipids, and both mRNA and noncoding RNAs. Since they can release their contents, particularly miRNAs, to both neighboring and distal cells, they are considered important in cell-cell communication. Recent evidence has shown their possible importance in the pathogenesis of several pulmonary diseases. The differential expression of exosomes and of exosomal miRNAs in disease has driven their promise as biomarkers of disease enabling noninvasive clinical diagnosis in addition to their use as therapeutic tools. In this review, we summarize recent advances in this area as applicable to pulmonary diseases.

    2017-01-01

    The risk of chronic obstructive pulmonary disease (COPD), as well as thyroid diseases increases with age. COPD is a common systemic disease associated with chronic inflammation. Many endocrinological disorders, including thyroid gland diseases are related to systemic inflammation. Epidemiological studies suggest that patients with COPD are at higher risk of thyroid disorders. These associations are not well-studied and thyroid gland diseases are not included on the broadly acknowledged list of COPD comorbidities. They may seriously handicap quality of life of COPD patients. Unfortunately, the diagnosis may be difficult, as many signs are masked by the symptoms of the index disease. The comprehension of the correlation between thyroid gland disorders and COPD may contribute to better care of patients. In this review, we attempt to revise available literature describing existing links between COPD and thyroid diseases.

    Ionescu, M

    1978-01-01

    The present paper reports on 12 patients (8 males, 4 females) suffering from chronic decompensated respiratory failure, who presented concomitant transient haemodynamic disturbances in the carotid and vertebrobasilary systems, manifested by hemisphere or brain stem symptoms. Owing to the adaptive capacity of these patients there exists a certain tolerance threshold to hypercapnic hypoxemia, but following accentuated or rapid aggravation of acid-base hypercapnic hypoxemia, the biological balance is abruptly perturbed leading to cerebral haemodynamic disturbances. The pathophysiological mechanism of production appears to be the accumulation of acid ions caused by pH acidification of the cerebrospinal fluid. Increase in the cerebral arterial output with decrease in the rate of circulation and vascular resistance take place especially in the vessels with atheromatous or hyaline lesions. Under conditions of severe acidosic hypercapnic hypoxemia this, nevertheless, insures a minimum of 10--20% oxygen required by the metabolism of the nerve cell, sufficient for maintaining the structure of the cell (vita minima). These vasculometabolic mechanisms explain why with improvement of haematosis, following remission of the decompensated disease and fall in acidotic hypercapnic hypoxemia values, the cerebral haemodynamic disturbances also show a more or less evident remission because the nerve cells having maintained their structure are able to take up their function again.

    Airway and/or lung remodeling, involving exaggerated extracellular matrix (ECM) protein deposition, is a critical feature common to pulmonary diseases including chronic obstructive pulmonary disease (COPD), asthma, and idiopathic pulmonary fibrosis (IPF). Fibulin-1 (Fbln1), an important ECM protein involved in matrix organization, may be involved in the pathogenesis of these diseases. We found that Fbln1 was increased in COPD patients and in cigarette smoke–induced (CS-induced) experimental COPD in mice. Genetic or therapeutic inhibition of Fbln1c protected against CS-induced airway fibrosis and emphysema-like alveolar enlargement. In experimental COPD, this occurred through disrupted collagen organization and interactions with fibronectin, periostin, and tenascin-c. Genetic inhibition of Fbln1c also reduced levels of pulmonary inflammatory cells and proinflammatory cytokines/chemokines (TNF-α, IL-33, and CXCL1) in experimental COPD. Fbln1c–/– mice also had reduced airway remodeling in experimental chronic asthma and pulmonary fibrosis. Our data show that Fbln1c may be a therapeutic target in chronic respiratory diseases.

    Viral infections and type 2 immune responses are thought to be critical for the development of chronic respiratory disease, but the link between these events needs to be better defined. Here, we study a mouse model in which infection with a mouse parainfluenza virus known as Sendai virus (SeV) leads to long-term activation of innate immune cells that drive IL-13–dependent lung disease. We find that chronic postviral disease (signified by formation of excess airway mucus and accumulation of M2-differentiating lung macrophages) requires macrophage expression of triggering receptor expressed on myeloid cells-2 (TREM-2). Analysis of mechanism shows that viral replication increases lung macrophage levels of intracellular and cell surface TREM-2, and this action prevents macrophage apoptosis that would otherwise occur during the acute illness (5–12 d after inoculation). However, the largest increases in TREM-2 levels are found as the soluble form (sTREM-2) long after clearance of infection (49 d after inoculation). At this time, IL-13 and the adapter protein DAP12 promote TREM-2 cleavage to sTREM-2 that is unexpectedly active in preventing macrophage apoptosis. The results thereby define an unprecedented mechanism for a feed-forward expansion of lung macrophages (with IL-13 production and consequent M2 differentiation) that further explains how acute infection leads to chronic inflammatory disease.

    The relationships between chronic liver diseases and trace element (TE) contents are debated. Particularly, no defined data are available about the TE levels in viral liver disease patients with or without malnutrition. In this study we evaluated blood and plasma levels of various trace elements in patients with HCV-related chronic liver disease, at different stages of liver damage (8 patients with chronic hepatitis and 32 with liver cirrhosis) with or without malnutrition. We also studied 10 healthy volunteers as control group. We found that cirrhotic subjects had a significant decrease of blood levels of Zn and Se, independently on the nutritional status, whereas plasma levels of Fe were significantly reduced only in malnourished cirrhotic patients. Our data indicate that liver impairment is the main cause of the blood decrease of Se and Zn levels in patients with non alcoholic liver disease, whereas the malnutrition affects Fe levels only.

    Full Text Available We describe a case of a 65-years-old patient with Chronic Obstructive Pulmonary Disease (COPD, receiving oxygen therapy and resistant to antibiotic therapy. He was admitted with high fever, productive cough, marked leukocytosis, and chest X-ray findings of infiltration and fluid levels within lung cysts. A differential diagnosis was essential to start an adequate treatment and avoid the rapid worsening of patients respiratory status. In patients with chronic pulmonary diseases under immunotherapy, micotic infections should be considered. Aspergillus fumigatus was cultured from bronchial washing fluid and we diagnosed chronic necrotizing pulmonary aspergillosis (CNPA. Oral itraconazole was started and his symptoms and laboratory data markedly improved.

    Asthma and chronic obstructive pulmonary disease (COPD) are heterogeneous inflammatory disorders of the respiratory tract characterized by airflow obstruction. It is now clear that the environmental factors that drive airway pathology in asthma and COPD, including allergens, viruses, ozone and cigarette smoke, activate innate immune receptors known as pattern-recognition receptors, either directly or indirectly by causing the release of endogenous ligands. Thus, there is now intense research activity focused around understanding the mechanisms by which pattern-recognition receptors sustain the airway inflammatory response, and how these mechanisms might be targeted therapeutically. One pattern-recognition receptor that has recently come to attention in chronic airways disease is the receptor for advanced glycation end products (RAGE). RAGE is a member of the immunoglobulin superfamily of cell surface receptors that recognizes pathogen- and host-derived endogenous ligands to initiate the immune response to tissue injury, infection and inflammation. Although the role of RAGE in lung physiology and pathophysiology is not well understood, recent genome-wide association studies have linked RAGE gene polymorphisms with airflow obstruction. In addition, accumulating data from animal and clinical investigations reveal increased expression of RAGE and its ligands, together with reduced expression of soluble RAGE, an endogenous inhibitor of RAGE signalling, in chronic airways disease. In this review, we discuss recent studies of the ligand-RAGE axis in asthma and COPD, highlight important areas for future research and discuss how this axis might potentially be harnessed for therapeutic benefit in these conditions.

    Full Text Available Over years,great strides have been made in theories and practices of mechanical ventilation.The indications of non-invasive ventilation have been increasing,while invasive ventilation has been playing a vital role in patients who are critically ill with inadequate drainage of sputum and fail to benefit from non-invasive ventilation.Chronic diseases,including chronic obstructive pulmonary disease(COPD,one of the most common chronic diseases,and bronchial asthma,the incidence of which is ascending recent years,are main causes for respiratory failure.Accordingly,we focus in the present paper on discussion and elaboration of respiratory failure as a result of COPD and bronchial asthma.Type II respiratory failure is the major type of respiratory failure induced by COPD,both in acute exacerbation and stable stage,and mechanical ventilation is one of the most common treatments.Severe acute bronchial asthma complicated with respiratory failure is an emergency.In this situation,primary goal of mechanical ventilation is to make an efficient oxygenation and ventilation of patients,and to avoid hyperinflation to the utmost.For patients who are able to cooperate,non-invasive ventilation in early stage may be beneficial,avoiding tracheal intubation and application of invasive ventilation.But in those who can not achieve remission in a short term,an artificial airway should be established for invasive ventilation as soon as possible.

  4. Obstructive sleep apnea in chronic obstructive pulmonary disease patients.

    2012-02-01

    PURPOSE OF REVIEW: Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) represent two of the most prevalent chronic respiratory disorders and cardiovascular diseases are major co-morbidities in both. Co-existence of both disorders (overlap syndrome) occurs in 1% of adults and overlap patients have worse nocturnal hypoxemia and hypercapnia than COPD and OSA patients alone. The present review discusses recent data concerning the pathophysiological and clinical significance of the overlap syndrome. RECENT FINDINGS: The severity of obstructive ventilatory impairment and hyperinflation, especially the inspiratory capacity to total lung capacity (TLC) ratio, correlates with the severity of sleep-related breathing disturbances. Early treatment with continuous positive airway pressure (CPAP) improves survival, reduces hospitalization and pulmonary hypertension, and also reduces hypoxemia. Evidence of systemic inflammation and oxidative stress in COPD and sleep apnea provides insight into potential interactions between both disorders that may predispose to cardiovascular disease. Long-term outcome studies of overlap patients currently underway should provide further evidence of the clinical significance of the overlap syndrome. SUMMARY: Studies of overlap syndrome patients at a clinical, physiological and molecular level should provide insight into disease mechanisms and consequences of COPD and sleep apnea, in addition to identifying potential relationships with cardiovascular disease.

    The bitter taste receptor T2R38 has been shown to play a role in the pathogenesis of chronic rhinosinusitis (CRS), where the receptor functions to enhance upper respiratory innate immunity through a triad of beneficial immune responses. Individuals with a functional version of T2R38 are tasters for the bitter compound phenylthiocarbamide (PTC) and exhibit an anti-microbial response in the upper airway to certain invading pathogens, while those individuals with a non-functional version of the receptor are PTC non-tasters and lack this beneficial response. The clinical ramifications are significant, with the non-taster genotype being an independent risk factor for CRS requiring surgery, poor quality-of-life (QOL) improvements post-operatively, and decreased rhinologic QOL in patients with cystic fibrosis. Furthermore, indirect evidence suggests that non-tasters also have a larger burden of biofilm formation. This new data may influence the clinical management of patients with infectious conditions affecting the upper respiratory tract and possibly at other mucosal sites throughout the body.

    Bovine respiratory disease (BRD) is the most common economically important disease affecting cattle. For developing accurate diagnostics that can predict disease susceptibility/resistance and stratification, it is necessary to identify the molecular mechanisms that underlie BRD. To study the complex interactions among the bovine host and the multitude of viral and bacterial pathogens, as well as the environmental factors associated with BRD etiology, genome-scale high-throughput functional genomics methods such as microarrays, RNA-seq, and proteomics are helpful. In this review, we summarize the progress made in our understanding of BRD using functional genomics approaches. We also discuss some of the available bioinformatics resources for analyzing high-throughput data, in the context of biological pathways and molecular interactions. Although resources for studying host response to infection are avail-able, the corresponding information is lacking for majority of BRD pathogens, impeding progress in identifying diagnostic signatures for BRD using functional genomics approaches.

    An excessive respiratory fluctuation (RTFV) in transmitral early diastolic velocity E is a pivotal Doppler echocardiographic sign of haemodynamic compromise, in constrictive pericardial diseases. RTFV is expressed as a percentage and 25% is considered a threshold value. Unfortunately there is no unanimity in calculating RTFV. Sometimes it is expressed as a percentage of expiratory E velocity, while others of inspiratory E velocity. This disparity has led to gross misinterpretations in medical literature. Here we emphasize the importance of a rational procedure calculating RTFV and we propose the appropriate mathematical model.

    The health gap between Indigenous and non-Indigenous Australians may be exacerbated by climate change if temperature extremes have disproportionate adverse effects on Indigenous people. To explore this issue, we analysed the effect of temperature extremes on hospital admissions for respiratory diseases, stratified by age, Indigenous status and sex, for people living in two different climates zones in the Northern Territory during the period 1993-2011. We examined admissions for both acute and chronic respiratory diagnoses, controlling for day of the week and seasonality variables. Our analysis showed that: (1) overall, Indigenous hospital admission rates far exceeded non-Indigenous admission rates for acute and chronic diagnoses, and Top End climate zone admission rates exceeded Central Australia climate zone admission rates; (2) extreme cold and hot temperatures were associated with inconsistent changes in admission rates for acute respiratory disease in Indigenous and non-Indigenous children and older adults; and (3) no response to cold or hot temperature extremes was found for chronic respiratory diagnoses. These findings support our two hypotheses, that extreme hot and cold temperatures have a different effect on hospitalisations for respiratory disease between Indigenous and non-Indigenous people, and that these health risks vary between the different climate zones. We did not, however, find that there were differing responses to temperature extremes in the two populations, suggesting that any increased vulnerability to climate change in the Indigenous population of the Northern Territory arises from an increased underlying risk to respiratory disease and an already greater existing health burden.

    1997-01-01

    This study explores and describes experiences of chronic liver disease from the patient's perspective. No qualitative research studies appear to have examined the experiences of these patients. In-depth focused interviews and grounded theory data collection and data analysis methods were used. A two-stage theoretical framework (becoming ill, and not living) of the experience of transcending chronic liver disease is presented. Sociological and psychological literature on common sense models of health and illness are briefly reviewed. Several suggestions for further research are made. The way in which this qualitative research study is leading to a quantitative and qualitative appraisal of the psychological adjustment in end-stage chronic liver disease patients is outlined.

    Full Text Available Background. There continues to be uncertainty on the ideal treatment of pruritus in chronic liver disease. The aim of this study was to gather the latest information on the evidence-based management of pruritus in chronic liver disease. Methodology. A literature search for pruritus in chronic liver disease was conducted using Pubmed and Embase database systems using the MeSH terms “pruritus,” “chronic liver disease,” “cholestatic liver disease,” and “treatment.” Results. The current understanding of the pathophysiology of pruritus is described in addition to detailing research into contemporary treatment options of the condition. These medical treatments range from bile salts, rifampicin, and opioid receptor antagonists to antihistamines. Conclusion. The burden of pruritus in liver disease patients persists and, although it is a common symptom, it can be difficult to manage. In recent years there has been greater study into the etiology and treatment of the condition. Nonetheless, pruritus remains poorly understood and many patients continue to suffer, reiterating the need for further research to improve our understanding of the etiology and treatment for the condition.

Material and methods: In a review of 50 studies, 27 were selected since these met the inclusion criteria, like chronical disease, studies conducted between 2002 and 2011 related to costs, chronic disease, and being Colombian. Results: This is a review study of chronic diseases vs. their costs, being here cardiovascular diseases part of the group of high cost and higher incidence diseases, thus repre­senting a great risk to the financial stability of healthcare companies. There are few studies that address the costs generated by the treatment of ncds patients that show the economic impact experienced by public and private institutions providing and promoting health services. Most of them forget the economic, family and social costs the affected population must suffer. Conclu­sions: ncds represent a burden to the health service system for their very high costs, untimely intervention and reduced significant benefit for this population and their families.

    Smoked cocaine (crack cocaine) causes several forms of injury to the respiratory tract, including asthma exacerbations, lung edema and hemorrhage, and nasal mucosal alterations. Few studies, however, have assessed respiratory tract pathology in habitual users of crack cocaine. Here, we describe the histological alterations in the respiratory tract of mice caused by chronic inhalation of crack cocaine. Twenty 2-month-old BALB/c mice were exposed to the smoke of 5 g crack cocaine in an inhalation chamber once a day for two months and compared to controls (n = 10). We then morphometrically analyzed nose and bronchiolar epithelial alterations, bronchiolar and alveolar macrophage cell density, alveolar hemosiderin content, and in addition determined the vasoconstriction index and the wall thickness of pulmonary arteries. The serum cocaine level was 212.5 ng/mL after a single inhalation. The mucus content of the nasal epithelium increased in crack-exposed animals, and the nasal and bronchial epithelium thickness decreased significantly. The alveolar hemosiderin content and the alveolar and bronchiolar macrophage cell density increased in animals exposed to crack. The vasoconstriction index increased in the pulmonary arteries of the exposed group. Chronic crack cocaine inhalation causes extensive histological changes along the entire respiratory tract.

    Background: Few studies have assessed the impact of residential home characteristics and home environmental risk factors on respiratory diseases in Chinese women. Therefore, this study sought to determine the association between residential home features, domestic pets, home renovation and other indoor environmental risk factors with respiratory health outcomes of Chinese women. Methods: This cross-sectional study included a study sample of 30,780 Chinese women aged 23 to 49 from 25 districts of seven cities in Liaoning Province, Northeast China. Information on respiratory health, residential characteristics, and indoor air pollution sources was obtained by a standard questionnaire from the American Thoracic Society. Multivariable logistic regression was used to estimate prevalence odds ratios (POR) and 95% confidence interval (95%CI). Results: The odds of respiratory diseases were higher for those who lived near the main road, or near ambient air pollution sources. Pet-keeping was associated with increased odds of chronic bronchitis (POR = 1.40; 95%CI: 1.09–1.81) and doctor-diagnosed asthma (POR = 2.07; 95%CI: 1.18–3.64). Additionally, humidifier use was associated with increased odds of chronic bronchitis (POR = 1.44; 95%CI: 1.07–1.94). Home renovation in recent 2 years was associated with increased likelihood of allergic rhinitis (POR = 1.39; 95%CI 1.17–1.64). Conclusion: Home renovation and residential home environmental risk factors were associated with an increased likelihood of respiratory morbidity among Chinese women. - Highlights: • Relatively few significant associations were observed. • Pet ownership was associated with increased odds of asthma and chronic bronchitis. • Home renovation was associated with increased odds of allergic rhinitis in women. • Humidifier use was associated with increased odds of chronic bronchitis in women.

The flux/content loop presents a graphic record of speed of flow of inhaled and exhaled air depending on volume of lungs. Seventy Donbass miners with pneumoconiosis and chronic bronchitis were investigated. Measurements were made of following parameters: speed of inhaled and exhaled air, vital capacity and speed of air at 75%, 50% and 25% of vital capacity. Miners were then treated with salbutamol, an antispasmodic, and same parameters measured. Results are presented in a table showing change in parameters of pneumotachography of exhalation during salbutamol tests. Following salbutamol course, patients with pneumconiosis had a positive reaction in 67% of cases, negative in 24%, none in 9%; those with chronic bronchitis had a positive reaction in 79% and negative in 21% of cases. Respiratory disturbances of lung diseases are due to dyskinesia of bronchioles. Failure to respond to salbutamol, a sympathomimetic, may be due to heightened tone of bronchioles due to parasympathetic innervation requiring a cholinolytic to open bronchiole pathways. Method of pneumotachography with registration of parameter of flow/content loop is combined with pharmacologic tests with antispasmodic preparations to reveal location and mechanism of disturbance of bronchial tone and to determine choice of adequate treatment. 8 refs.

    Full Text Available During the past decades there was an increasing predominance of chronic disorders, with a large number of people living with chronic diseases that can adversely affect their quality of life. The aim of the present paper is to study quality of life and especially Health-related quality of life (HRQoL in chronic diseases. HRQOL is a multidimensional construct that consists of at least three broad domains − physical, psychological, and social functioning − that are affected by one’s disease and/or treatment. HRQoL is usually measured in chronic conditions and is frequently impaired to a great extent. In addition, factors that are associated with good and poor HRQoL, as well as HRQoL assessment will be discussed. The estimation of the relative impact of chronic diseases on HRQoL is necessary in order to better plan and distribute health care resources aiming at a better HRQoL.[«All the people perceive the concept of living good or being well, that is the same as being happy».

    Cirrhotic patients are known to have abnormally high signal principally in the globus pallidus on non-contrast T1-weighted MRI. The purpose of this study was to relate MR changes to clinical and pathological features of chronic liver disease. We confirmed abnormally high signal in the globus pallidus on T1-weighted images in 25 of 28 patients with chronic liver disease, showing that it also occurs in patients who have not yet progressed to cirrhosis. Changes were seen in patients both with and without clinical portosystemic shunting. This abnormality is not responsible for hepatic encephalopathy. Cholestatic disease was more likely to produce marked changes than non-cholestatic disease. No statistically significant correlation was demonstrated between the severity of liver disease and the degree of MR abnormality. However, marked improvement in MR appearances was seen after successful liver transplantation. (orig.). With 3 figs., 4 tabs.

    We report six cases of autoimmune thyroid disease associated with chronic urticaria and briefly review the literature, including the histopathological nature of such lesions, and their aetiology and pathogenesis. In view of the prevalence of thyroid disease in patients with chronic urticaria, screening measurements of thyrotropin and anti-thyroperoxidase antibodies are recommended, although negative antibodies do not exclude a relationship between urticaria and thyroid autoimmunity. After failure of conventional therapy for urticaria, patients who are apparently clinically euthyroid may be considered for a trial with levothyroxine. Improvement of urticaria was seen with levothyroxine treatment in three of four patients with only marginal abnormalities in thyroid function.

    Chronic parotitis is a troubling clinical condition characterized by repeated infection and inflammation of the parotid gland caused by decreased salivary flow or obstruction. Unilateral swelling, pain, and other associated symptoms occur during acute exacerbations of the disease. A variety of laboratory and radiographic tools are available to aid in the diagnosis. Multiple treatment options have been proposed, ranging from conservative medical management to surgical interventions. We present 2 patients with bilateral chronic parotitis who attempted prolonged medical management and ultimately required surgical parotidectomy for control of their disease.

  4. Long-term trends in cardiovascular disease mortality and association with respiratory disease.

    The recent decline in cardiovascular disease mortality in Western countries has been linked with changes in life style and treatment. This study considers periods of decline before effective medical interventions or knowledge about risk factors. Trends in annual age-standardized death rates from cerebrovascular disease, heart disease and circulatory disease, and all cardiovascular disease are reviewed for three phases, 1881-1916, 1920-1939, and 1940-2000. There was a consistent decline in the cerebrovascular disease death rate between 1891 and 2000, apart from brief increases after the two world wars. The heart disease and circulatory disease death rate was declining between 1891 and 1910 before cigarette smoking became prevalent. The early peak in cardiovascular mortality in 1891 coincided with an influenza pandemic and a peak in the death rate from bronchitis, pneumonia and influenza. There is also correspondence between short-term fluctuations in the death rates from these respiratory diseases and cardiovascular disease. This evidence of ecological association is consistent with the findings of many studies that seasonal influenza can trigger acute myocardial infarction and episodes of respiratory infection are followed by increased risk of cardiovascular events. Vaccination studies could provide more definitive evidence of the role in cardiovascular disease and mortality of influenza, other viruses, and common bacterial agents of respiratory infection.

    Research from the wars in Afghanistan and Iraq have focused on traumatic brain injury (TBI) and mental health conditions; however, it is becoming clear that other health concerns, such as respiratory illnesses, warrant further scientific inquiry. Early reports from theater and postdeployment health assessments suggested an association with deployment-related exposures (e.g., sand, burn pits, chemical, etc.) and new-onset respiratory symptoms. We used data from Veterans Affairs medical encounters between fiscal years 2003 and 2011 to identify trends in chronic obstructive pulmonary disease, asthma, and interstitial lung disease in veterans. We used data from Veterans Affairs and Department of Defense sources to identify sociodemographic (age, sex, race), military (e.g., service branch, multiple deployments) and clinical characteristics (TBI, smoking) of individuals with and without chronic lung diseases. Generalized estimating equations found significant increases over time for chronic obstructive pulmonary disease and asthma in both unadjusted and adjusted analyses. Trends for interstitial lung disease were significant only in adjusted analyses. Age, smoking, and TBI were also significantly associated with chronic lung diseases; however, multiple deployments were not associated. Research is needed to identify which characteristics of deployment-related exposures are linked with chronic lung disease.

    Full Text Available Chronic obstructive pulmonary disease (COPD is associated with a chronic inflammatory response in airways and lung parenchyma that results in significant morbidity and mortality worldwide. Cigarette smoking considered as an important risk factor plays a role in pathogenesis of disease. Pneumocystis jirovecii is an atypical opportunistic fungus that causes pneumonia in immunosuppressed host, although the low levels of its DNA in patients without signs and symptoms of pneumonia, which likely represents colonization. The increased prevalence of P. jirovecii colonization in COPD patients has led to an interest in understanding its role in the disease. P. jirovecii colonization in these patients could represent a problem for public health since colonized patients could act as a major reservoir and source of infection for susceptible subjects. Using sensitive molecular techniques, low levels of P. jirovecii DNA have been detected in the respiratory tract of certain individuals. It is necessary to elucidate the role of P. jirovecii colonization in the natural history of COPD patients in order to improve the clinical management of this disease. In the current review paper, we discuss P. jirovecii colonization in COPD patients.

    Objective To investigate the influential factors of compliance of respiratory function exercise in elderly patients with chronic obstructive pulmonary disease (COPD). Methods A survey was conducted to 50 elderly patients with COPD in order to understand their respiratory function exercise conditions. Results Among 50 COPD patients,30 patients (60%) knew the respiratory function exercise and believed its effectiveness. In these 30 patients,only 10 patients performed everyday,15 performed occasionally,5 started the exercise but gave up halfway and 20 (40% ) have never heard the respiratory function exercise. About the source of the exercise knowledge,10 patients reported that it came from doctor (20%),18 from nurses (36% ),2 from other channels such as medium/internet/book (4 %) and 15 from guidance (30 % ). Conclusion Once patients cannot completely and effectively get the relevant knowledge of respiratory function exercise,the nursing staff should take various actions to strengthen education,normalize the exercise and enhance the compliance of the patient,so as to delay the development of the disease and improve the living condition of the patients.%目的 探讨影响老年慢性阻塞性肺疾病(COPD)患者呼吸功能锻炼依从性的原因.方法 对50例老年慢性阻塞性肺疾病患者进行问卷调查分析,了解患者掌握呼吸功能锻炼的状况.结果 发现50例COPD患者中知道呼吸功能锻炼并认为对疾病有帮助的患者有30例(60%),其中能每天坚持锻炼的10例,偶尔进行呼吸功能锻炼的15例,开始做后来不做呼吸功能锻炼的5例;没听过呼吸功能锻炼的患者20例(40%).关于呼吸功能锻炼知识的来源,来自医生的10例(20%),护士18例(36%),其他(媒体、网络、书籍等)2例(4%),有指导地进行呼吸功能锻炼的15例(30%).结论 患者不能得到完整有效的呼吸功能锻炼的相关知识,护理人员须采取多种形式,加强相关知识的宣教,在实践

    Suau, Salvador J; DeBlieux, Peter M C

    2016-02-01

    Acute asthma and chronic obstructive pulmonary disease (COPD) exacerbations are the most common respiratory diseases requiring emergent medical evaluation and treatment. Asthma and COPD are chronic, debilitating disease processes that have been differentiated traditionally by the presence or absence of reversible airflow obstruction. Asthma and COPD exacerbations impose an enormous economic burden on the US health care budget. In daily clinical practice, it is difficult to differentiate these 2 obstructive processes based on their symptoms, and on their nearly identical acute treatment strategies; major differences are important when discussing anatomic sites involved, long-term prognosis, and the nature of inflammatory markers.

    @@ The term chronic obstructive pulmonary disease (COPD) has been well known and the disease extensively studied for more than a decade in China, but only recently has great progress been made in the epidemiology and management of this highly prevalent disease in this country. Historically, beginning in the early 1960s, long before the definition of COPD was widely accepted, a great number of studies that included traditional Chinese medicine had been performed on chronic bronchitis, emphysema, and related respiratory failure and cor pulmonale.

    2007-08-01

    A survey was conducted in a meeting sponsored by ALAT (Latin American Association of Thoracic Diseases). Each of the seven editors reported about their journal and answered a questionnaire. The improvement in knowledge divulgation is the main motivation of respiratory societies to edit their own journals. To disseminate medical knowledge and report experiences, are the main motivations of authors to submit papers. The most common deficiency of submitted manuscripts is a bad compliance with journal requirements. An improvement in the relationship between author-editor-reviewer should be the best strategy to enhance the quality of the manuscripts. Suggestions to improve the Latin American journals included to professionalize editorial work, to increase the meticulousness of manuscripts reviewers and to reinforce international norms for editing medical journals. Some major problems reported were a lack of a regular and adequate periodicity in publishing the issues, lack of original papers submitted that mean a "milestone" for the specialty a low percentage of submitted papers rejection and a high and frequent turnover of editors. Although several journals are available in electronic indices, they should be maintained in their printed form. Each journal should have printed its subscription fee, even considering that its subscription is included in the annual society membership fee. The feasibility to generate a multinational Latin American Journal on Respiratory Diseases should be explored.

    Full Text Available Abstract Background Recent studies have confirmed the presence of viable Chlamydia in the bronchoalveolar lavage (BAL fluid of pediatric patients with airway hyperresponsiveness. While specific IgG and IgM responses to C. pneumoniae are well described, the response and potential contribution of Ag-specific IgE are not known. The current study sought to determine if infection with Chlamydia triggers the production of pathogen-specific IgE in children with chronic respiratory diseases which might contribute to inflammation and pathology. Methods We obtained BAL fluid and serum from pediatric respiratory disease patients who were generally unresponsive to corticosteroid treatment as well as sera from age-matched control patients who saw their doctor for wellness checkups. Chlamydia-specific IgE was isolated from BAL and serum samples and their specificity determined by Western blot techniques. The presence of Chlamydia was confirmed by species-specific PCR and BAL culture assays. Results Chlamydial DNA was detected in the BAL fluid of 134/197 (68% patients. Total IgE increased with age until 15 years old and then decreased. Chlamydia-specific IgE was detected in the serum and/or BAL of 107/197 (54% patients suffering from chronic respiratory disease, but in none of the 35 healthy control sera (p p = 0.0001 tested positive for Chlamydia-specific IgE. Asthmatic patients had significantly higher IgE levels compared to non-asthmatics (p = 0.0001. Patients who were positive for Chlamydia DNA or culture had significantly higher levels of serum IgE compared to negative patients (p = 0.0071 and p = 0.0001 respectively. Only 6 chlamydial antigens induced Chlamydia-specific IgE and patients with C. pneumoniae-specific IgE had significantly greater levels of total IgE compared to C. pneumoniae-specific IgE negative ones (p = 0.0001. Conclusions IgE antibodies play a central role in allergic inflammation; therefore production of Chlamydia

    Asthma and chronic obstructive pulmonary disease (COPD) are chronic diseases, very common in general population. These obstructive airway illnesses are manifested with chronic inflammation affecting the whole respiratory tract. Obstruction is usually intermittent and reversible in asthma, but is progressive and irreversible in COPD. Asthma and COPD may overlap and converge, especially in older people [overlap syndrome—asthma-chronic obstructive pulmonary disease overlap syndrome (ACOS)]. Although ACOS accounts approximately 15-25% of the obstructive airway diseases, is not well recognised because of the structure of clinical trials. COPD studies exclude asthma patients and asthma studies exclude COPD patients, respectively. It is crucial to define asthma, COPD and overlap syndrome (ACOS), as notable clinical entities, which they share common pathologic and functional features, but they are characterized from differences in lung function, acute exacerbations, quality of life, hospital impact and mortality.

    Full Text Available A morbidity and mortality study took place, focused on Milos Island, where perlite and bentonite mining sites are located. Official data concerning number and cause of deaths, regarding specific respiratory diseases and the total of respiratory diseases, for both Milos Island and the Cyclades Prefecture were used. Standardized Mortality Ratios (SMRs were computed, adjusted specifically for age, gender and calendar year. Tests of linear trend were performed. By means of a predefined questionnaire, the morbidity rates of specific respiratory diseases in Milos, were compared to those of the municipality of Oinofita, an industrial region. Chi-square analysis was used and the confounding factors of age, gender and smoking were taken into account, by estimating binary logistic regression models. The SMRs for Pneumonia and Chronic Obstructive Pulmonary Disease (COPD were found elevated for both genders, although they did not reach statistical significance. For the total of respiratory diseases, a statistically significant SMR was identified regarding the decade 1989–1998. The morbidity study revealed elevated and statistically significant Odds Ratios (ORs, associated with allergic rhinitis, pneumonia, COPD and bronchiectasis. An elevated OR was also identified for asthma. After controlling for age, gender and smoking, the ORs were statistically significant and towards the same direction.

    2014-11-01

    Socioeconomic differences in morbidity and mortality, particularly across educational groups, are widening. Differential exposures to behavioural risk factors have been shown to play an important mediating role on the social inequality in chronic diseases such as heart disease, cerebrovascular disease, chronic obstructive pulmonary disease, and lung cancer. However, much less attention has been given to the potential role of interaction, where the same level of exposure to a behavioural risk factor has different effect across socioeconomic groups, creating subgroups that are more vulnerable than others. In this thesis, Paper 1 describes the unique cohort consortium which was established by pooling and harmonising prospective data from existing cohort studies in Denmark. This consortium generated a large study population with long follow-up sufficient to study power demanding questions of mechanisms underlying social inequalities in chronic disease outcomes. In Paper 2 on incidence of coronary heart disease, smoking and body mass index partially mediated the observed educational differences. This result suggested that some of the social inequality in coronary heart disease may be enhanced by differential exposure to behavioural risk factors (i.e. smoking and obesity). In Paper 3 on incidence of stroke, an observed interaction between education and smoking indicated that participants, particularly men, with low level of education may be more vulnerable to the effect of smoking than those with high level of education in terms of ischemic stroke. Finally, Paper 4 revealed that behavioural risk factors, primarily smoking, explained a considerable part of the educational differences in cause-specific mortality. Further, this paper added important knowledge about the considerable part of the mediated effect, which could be due to interaction between education and smoking. In conclusion, the research in this thesis is a practical implementation of contemporary statistical

    Interleukin (IL)-10 is an important immunoregulatory cytokine produced by many cell populations. Numerous investigations suggest that IL-10 plays a major role in chronic liver diseases. IL-10 gene polymorphisms are possibly associated with liver disease susceptibility or severity. Recombinant human IL-10 has been produced and is currently tested in clinical trials. These trials may give new insights into the immunobiology of IL-10 and suggest that the IL-10/IL-10 receptor system may become a new therapeutic target.

    Full Text Available In this article, I present a phenomenological study of individuals’ experiences of living with moderate to very severe chronic lower pulmonary disease (chronic obstructive pulmonary disease, asthma, or both. Phenomenology is a philosophy, distinct from descriptive or thematic research, which is useful as a foundation for scientific inquiry. In this study, I used the lens of Merleau-Ponty to understand and interpret participants’ experiences of living with pulmonary disease, and the approach of van Manen for analysis. I conclude that in chronic pulmonary disease, awareness of breathing and the body is experienced in the sounds, sensations, and signals of breathing and the body, and in the experiences of the body-in-the-world. Central themes of being-in-the-world from the study describe the disruption of the embodied phenomenological self: Participants experienced slowing down, doing less, and having to stop due to shortness of breath. Both chronic and acute dyspnea were prevalent and the taken-for-granted aspects of daily activities were disrupted. Findings of this study have implications for public and patient education, and opportunities for integration of experiential aspects within nursing education and practice.

    Background Chronic obstructive pulmonary disease (COPD) has a variable natural history and not all individuals follow the same course. This study aimed to identify the prevalence and characteristics of asymptomatic COPD patients from a population-based survey in China.Methods A multistage cluster sampling strategy was used in a population from seven different provinces/cities. All residents (over 40 years old) were interviewed with a standardized questionnaire and spirometry.Post-bronchodilator forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) of less than 70% was defined as the diagnostic criterion of COPD. All COPD patients screened were divided into symptomatic group and asymptomatic group according to the presence or absence of chronic respiratory symptoms. Socio-demographic,personal and exposure variables were collected and analyzed.Results Among the 1668 patients who were diagnosed with COPD from the 25 627 sampling subjects, 589 (35.3%)were asymptomatic. The age, sex, body mass index (BMI),rural and urban distributions, smoking habit and education levels were similar in the two groups. A total of 64.7% of the asymptomatic patients had no comorbidities. Cardiovascular diseases and lung cancer were more common among symptomatic COPD patients than asymptomatic group.Asymptomatic COPD group were less likely to present with poor ventilation in the kitchen, a family history of respiratory disease and recurrent childhood cough. Asymptomatic COPD patients had significantly higher FEV1 (73.1% vs. 61.0%), FVC (91.9% vs. 82.0%), and a higher ratio of FEV1/FVC (62.9% vs.58.7%) (all P <0.001) than symptomatic group. More asymptomatic patients were underdiagnosed (91.9% vs.54.3%, P<0.001) than symptomatic patients.Conclusions This large population-based survey confirmed a high prevalence of asymptomatic COPD patients in China. More use of spirometry screening test may be important to the early detection of COPD.

    2014-06-01

    Full Text Available Chronic inflammatory diseases are associated with accelerated atherosclerosis and increased risk of cardiovascular diseases (CVD. As the pathogenesis of atherosclerosis is increasingly recognized as an inflammatory process, similarities between atherosclerosis and systemic inflammatory diseases such as rheumatoid arthritis, inflammatory bowel diseases, lupus, psoriasis, spondyloarthritis and others have become a topic of interest. Endothelial dysfunction represents a key step in the initiation and maintenance of atherosclerosis and may serve as a marker for future risk of cardiovascular events. Patients with chronic inflammatory diseases manifest endothelial dysfunction, often early in the course of the disease. Therefore, mechanisms linking systemic inflammatory diseases and atherosclerosis may be best understood at the level of the endothelium. Multiple factors, including circulating inflammatory cytokines, TNF-α (tumor necrosis factor-α, reactive oxygen species, oxidized LDL (low density lipoprotein, autoantibodies and traditional risk factors directly and indirectly activate endothelial cells, leading to impaired vascular relaxation, increased leukocyte adhesion, increased endothelial permeability and generation of a pro-thrombotic state. Pharmacologic agents directed against TNF-α-mediated inflammation may decrease the risk of endothelial dysfunction and cardiovascular disease in these patients. Understanding the precise mechanisms driving endothelial dysfunction in patients with systemic inflammatory diseases may help elucidate the pathogenesis of atherosclerosis in the general population.

    1997-01-01

    Full Text Available Chronic obstructive pulmonary disease (COPD is associated with primary respiratory impairment, disability and handicap, as well as with secondary impairments not necessarily confined to the respiratory system. Because the primary goals of managing patients with COPD include relief of dyspnea and the improvement of health-related quality of life (HRQL, a direct measurement of HRQL is important. Fourteen disease-specific and nine generic questionnaires (four health profiles and five utility measures most commonly used to measure health status in patients with COPD were reviewed. The measures were classified according to their domain of interest, and their measurement properties - specifications, validity, reliability, responsiveness and interpretability - were described. This review suggests several findings. Currently used health status instruments usually refer to the patients’ perception of performance in three major domains of HRQL - somatic sensation, physical and occupational function, and psychological state. The choice of a questionnaire must be related to its purpose, with a clear distinction being made between its evaluative and discriminative function. In their evaluative function, only a few instruments fulfilled the criteria of responsiveness, and the interpretability of most questionnaires is limited. Generic questionnaires should not be used alone in clinical trials as evaluative instruments because of their inability to detect change over time. Further validation and improved interpretability of existing instruments would be of greater benefit to clinicians and scientists than the development of new questionnaires.

    Full Text Available Abstract Treatment of patients with chronic diseases will be one of the main challenges of medicine in the future. This paper presents an overview of different origins, mechanism, and symptoms necessary for understanding new and different interventions that include a psychosomatic view. In a psychosomatic therapeutic intervention there are very different targets, such as psychological symptoms, personality traits, attitudes toward disease and life, risk behaviour, and social isolation and as biological targets the change of autonomic imbalance and of the effects of the psycho-endocrinological or psycho-immunological stress responses. And there are also different psychosomatic measures that influence the individual biological, psychological and sociological targets. There is a need to give different answer to different questions in the field of psychosomatic and behavioral medicine. Comparative effectiveness research is an important strategy for solving some methodological issues. What is the target of treatment for different diseases: Symptom reduction, healing, or limiting progression to the worst case - the death of patients. We know that, the patient-physician relationship is important for every medical/therapeutic action for patients with chronic diseases. This volume of BioPsychoSocial Medicine will present four different psychosomatic treatment studies from the clinical field in the sense of phase 2 studies: Reports of patients with obesity, anorexia nervosa, chronic somatoform pain and coronary artery disease were presented

    Full Text Available Epidemiological and experimental studies have consistently linked alcoholic beverage consumption with the development of several chronic disorders, such as cancer, cardiovascular diseases, diabetes mellitus and obesity. The impact of drinking is usually dose-dependent, and light to moderate drinking tends to lower risks of certain diseases, while heavy drinking tends to increase the risks. Besides, other factors such as drinking frequency, genetic susceptibility, smoking, diet, and hormone status can modify the association. The amount of ethanol in alcoholic beverages is the determining factor in most cases, and beverage types could also make an influence. This review summarizes recent studies on alcoholic beverage consumption and several chronic diseases, trying to assess the effects of different drinking patterns, beverage types, interaction with other risk factors, and provide mechanistic explanations.

    Since antiquity, ginger or Zingiber officinale, has been used by humans for medicinal purposes and as spice condiments to enhance flavor in cooking. Ginger contains many phenolic compounds such as gingerol, shogaol and paradol that exhibit antioxidant, anti-tumor and anti-inflammatory properties. The role of ginger and its constituents in ameliorating diseases has been the focus of study in the past two decades by many researchers who provide strong scientific evidence of its health benefit. This review discusses research findings and works devoted to gingerols, the major pungent constituent of ginger, in modulating and targeting signaling pathways with subsequent changes that ameliorate, reverse or prevent chronic diseases in human studies and animal models. The physical, chemical and biological properties of gingerols are also described. The use of ginger and especially gingerols as medicinal food derivative appears to be safe in treating or preventing chronic diseases which will benefit the common population, clinicians, patients, researchers, students and industrialists.

    Objective To determine the effect of bi- level positive airway pressure ventilation (Bi- PAP) in elderly do- not- intubate patients with acute exacerbation chronic obstructive pulmonary disease (AECOPD) and respiratory failure. Methods 65 elderly patients who were admitted to intensive care unit from September 2006 to December 2010 with acute exacerbation chronic obstructive pulmonary disease (AECOPD) and respiratory failure were randomly divided into 2 groups standard group (re =32) and Bi-PAP group (re =33) . The changes of consciousness, physiological parameters, hospital mortality and adverse events in patients were compared between the two groups. Results The baseline characters of patients were similar in both the Bi- PAP and standard therapy groups. After 2 hour of treatment, GCS scores of patients in Bi-PAP group (P<0.01) and median (5th-95th percentile) PaO2/FIO2 ratios were significantly higher [182 (77-384) vs 165 (70-358), P<0.0l] , and PaCO2 was lower than standard group [55 (31~86) mmHg vs 82 (47 - 107) mmHg, P<0.0l]. Treatment with Bi-PAP successfully reduced the hospital mortality [11 (33%) vs 24 (75%), P< 0.01]. It looked similar with adverse events occurred both Bi-PAP and standard treatment. Conclusion For elderly do-not-intubate patients with AECOPD and respiratory failure, treatment with Bi- PAP not only can improve the patient's physiological parameters, but also improve the patient's outcomes.%目的 观察双水平正压通气(Bi-PAP)在拒绝插管(Do-not-intubate)的老年慢件阻塞性肺病急性加重(AECOPD)呼吸衰竭病人的疗效.方法 2006年9月至2010年12月65名入住重症监护病房的老年慢性阻塞性肺病急性加重呼吸衰竭病人纳入研究.将病人随机分为普通治疗组(n=32)和Bi-PAP(n=33)组.比较2组病人研究期间的意识变化、生理学参数的变化、院内死亡率及不良事件发生率.结果 老年慢性阻塞性肺病急性加重呼吸衰竭无创通气组与普通治疗

    Cara N Halldin

    Full Text Available BACKGROUND: Bronchiolitis obliterans, an irreversible lung disease, was first associated with inhalation of butter flavorings (diacetyl in workers at a microwave popcorn company. Excess rates of lung-function abnormalities were related to cumulative diacetyl exposure. Because information on potential excess mortality would support development of permissible exposure limits for diacetyl, we investigated respiratory-associated mortality during 2000-2011 among current and former workers at this company who had exposure to flavorings and participated in cross-sectional surveys conducted between 2000-2003. METHODS: We ascertained workers' vital status through a Social Security Administration search. Causes of death were abstracted from death certificates. Because bronchiolitis obliterans is not coded in the International Classification of Disease 10(th revision (ICD-10, we identified respiratory mortality decedents with ICD-10 codes J40-J44 which encompass bronchitis (J40, simple and mucopurulent chronic bronchitis (J41, unspecified chronic bronchitis (J42, emphysema (J43, and other chronic obstructive pulmonary disease (COPD (J44. We calculated expected number of deaths and standardized mortality ratios (SMRs with 95% confidence intervals (CI to determine if workers exposed to diacetyl experienced greater respiratory mortality than expected. RESULTS: We identified 15 deaths among 511 workers. Based on U.S. population estimates, 17.39 deaths were expected among these workers (SMR = 0.86; CI:0.48-1.42. Causes of death were available for 14 decedents. Four deaths among production and flavor mixing workers were documented to have a multiple cause of 'other COPD' (J44, while 0.98 'other COPD'-associated deaths were expected (SMR = 4.10; CI:1.12-10.49. Three of the 4 'other COPD'-associated deaths occurred among former workers and workers employed before the company implemented interventions reducing diacetyl exposure in 2001. CONCLUSION: Workers

    Full Text Available Prolonged cough occurs in a large proportion of the 2 million pilgrims who participate in the annual Hajj in Saudi Arabia. There is no unique cause for pilgrims’ respiratory involvement, but several studies suggest a high incidence of influenza as a cause of the disease. To determine influenza vaccine efficacy against respiratory disease in pilgrims, we conducted two similar cohort studies on 51100 Iranian pilgrims who had participated in the annual Hajj in the years 2003 and 2004. We calculated vaccine efficacy in these two years with the use of “1- odd’s ratio” formula and compared the results. The vaccine efficacy for prevention of influenza like illness in the year 2003 was 51% but the vaccine was not efficient in the year 2004. It was concluded that etiologic agents other than influenza virus should be considered as the cause of respiratory disease in Hajj. Bacterial infections superimposed on chronic respiratory diseases, and allergic or toxic conditions are suggested caourses for more investigation.

    Male sexual dysfunction is common in chronic kidney disease (CKD), particularly in end-stage renal disease. Historically, this cause of considerable morbidity has been under-reported and under-recognized. The ideal approach to diagnosis and management remains unclear due to a paucity of good quality data, but an understanding of the pathophysiology is necessary in order to address the burden of this important complication of CKD. This paper will review the endocrine dysfunction that occurs in renal disease, particularly the hypothalamic–pituitary–gonadal axis, discuss the causes of erectile dysfunction, infertility, and altered body image and libido in these patients and suggest appropriate treatment interventions.

    Since liver function is changed by chronic liver diseases, chronic liver disease can lead to different hemorheological alterations during the course of the progression. This study aims to compare alterations in whole blood viscosity in patients with chronic liver disease, focusing on the gender effect. Chronic liver diseases were classified into three categories by patient's history, serologic markers, and radiologic findings: nonalcoholic fatty liver disease (NAFLD) (n = 63), chronic viral hepatitis B and C (n = 50), and liver cirrhosis (LC) (n = 35). Whole blood viscosity was measured by automated scanning capillary tube viscometer, while liver stiffness was measured by transient elastography using FibroScan®. Both systolic and diastolic whole blood viscosities were significantly lower in patients with LC than NAFLD and chronic viral hepatitis (P chronic viral hepatitis. Our data suggest that whole blood viscosity test can become a useful tool for classifying chronic liver disease and determining the prognosis for different types of chronic liver diseases.

    Chronic lower airway diseases, including chronic obstructive pulmonary disease (COPD) and asthma, are currently the third leading cause of death in the United States. We aimed to evaluate changes in prevalence of and risk factors for COPD and asthma among the US adult population. We evaluated changes in prevalence of self-reported doctor-diagnosed COPD (i.e. chronic bronchitis and emphysema) and asthma and self-reported respiratory symptoms comparing data from the 1988-1994 and 2007-2010 National Health and Nutrition Examination Surveys. To investigate changes in the severity of each outcome over the two periods, we calculated changes in the proportions of spirometry-based airflow obstruction for each outcome. Prevalence of doctor-diagnosed chronic bronchitis and emphysema decreased significantly mainly among males, while asthma increased only among females. The self-reported disease and the respiratory symptoms were associated with increased prevalence of airflow obstruction for both periods. However, the prevalence of airflow obstruction decreased significantly in the second period among those with shortness of breath and doctor-diagnosed respiratory conditions (chronic bronchitis, emphysema, and asthma). COPD outcomes and asthma were associated with lower education, smoking, underweight and obesity, and occupational dusts and fumes exposure. Chronic lower airway diseases continue to be major public health problems. However, decreased prevalence of doctor-diagnosed chronic bronchitis and emphysema (in males) and decreased prevalence of airflow obstruction in those with respiratory symptoms and doctor-diagnosed respiratory diseases may indicate a declining trend and decrease in disease severity between the two periods. Continued focus on prevention of these diseases through public health interventions is prudent.

    Motor neurone disease is a neurodegenerative condition with a significant morbidity and shortened life expectancy. Hypoventilatory respiratory failure is the most common cause of death and respiratory function significantly predicts both survival and quality of life in patients with motor neurone disease. Accordingly, supporting and maintaining respiratory function is important in caring for these patients. The most significant advance in motor neurone disease care of recent years has been the domiciliary provision of non-invasive ventilation for treating respiratory failure. Neuromuscular respiratory weakness also leads to ineffective cough and retained airways secretions, predisposing to recurrent chest infections. In this review, we discuss current practice and recent developments in the respiratory management of motor neurone disease, in terms of ventilatory support and cough augmentation.

Materials and methods: Longitudinal analysis of data from the Swedish National Register of COPD with breathlessness measured using modified Medical Research Council (mMRC scores at two subsequent visits. Prevalence of disabling breathlessness (mMRC ≥2 at baseline and persistent disabling breathlessness (disabling breathlessness at baseline and follow-up was investigated in relation to COPD treatment. Risk factors for disabling breathlessness, change from non-disabling to disabling breathlessness, and persistent disabling breathlessness were analyzed using multiple logistic regression. Results: A total of 1,689 patients were included in the study with a median follow-up of 12 months (interquartile range: 4 months. Prevalence of disabling breathlessness was 54% at baseline. Persistent disabling breathlessness was present in 43% of patients despite treatment and in 74% of patients despite combined inhaled triple therapy and physiotherapy. Risk factors for disabling breathlessness or change to disabling breathlessness were higher age, lower lung function, frequent exacerbations, obesity, heart failure, depression, and hypoxic respiratory failure (all P<0.05. Persistent disabling breathlessness was associated with lower lung function and ischemic heart disease (all P<0.05. Conclusion: Disabling breathlessness is common in COPD despite treatment, which calls for improved symptomatic treatments and consideration of factors influencing disabling breathlessness.

    The observational evidence indicates that recent regional changes in climate, particularly temperature increases, have already affected a diverse set of physical and biological systems in many parts of the world. Allergens patterns are also changing in response to climate change and air pollution can modify the allergenic potential of pollen grains especially in the presence of specific weather conditions. Although genetic factors are important in the development of asthma and allergic diseases, their rising trend can be explained only by changes occurring in the environment and urban air pollution by motor vehicles has been indicated as one of the major risk factors responsible for this increase. Despite some differences in the air pollution profile and decreasing trends of some key air pollutants, air quality is an important concern for public health in the cities throughout the world. Due to climate change, air pollution patterns are changing in several urbanized areas of the world with a significant effect on respiratory health. The underlying mechanisms of all these interactions are not well known yet. The consequences on health vary from decreases in lung function to allergic diseases, new onset of diseases, and exacerbation of chronic respiratory diseases. In addition, it is important to recall that an individual's response to pollution exposure depends on the source and components of air pollution, as well as meteorological conditions. Indeed, some air pollution-related incidents with asthma aggravation do not depend only on the increased production of air pollution, but rather on atmospheric factors that favor the accumulation of air pollutants at ground level. Associations between thunderstorms and asthma morbidity of pollinosis-affected people have also been identified in multiple locations around the world (Fig.1).

    Sometimes, antitussives can be a valid adjuvant to respiratory tract infections treatment. Although not always needed, this therapeutic support can be extremely useful in selected cases, and when patient is resident and monitored. In this line, the efficacy of a new peripheral antitussive, levodropropizine (Dompé farmaceutici, Milan), has been evaluated in 70 children inpatients of the Pediatric Department at san Paolo Hospital - Milan University - from September 1987 to May 1988. Thirty one male and 29 female children, aged 4 years and 6 months +/- 3 years and 5 months, suffering from various respiratory tract diseases were included in the study. Underlying diseases were represented by 21 acute bronchitis, 20 asthmatic attacks, 18 bronchopneumonia, 11 tracheitis, 6 acute episodes of chronic bronchitis, 2 hypoglottis laryngitis, 1 pertussis, 1 spontaneous pneumothorax. All parents gave their oral informed consent. The basic treatments were antibiotics in 44 patients associated or not with beta 2 agonists (31), theophylline (15), corticosteroids via aerosol (9) or parenterally (3), immunomodulators (2). Treatment with levodropropizine in the oral drops formulation at 2 mg pro kg a day was continued for 5 days and withdrawn according to the clinical evolution. Cough was registered by means of appropriate record forms given to the parents as well as with 120' tape recording whenever possible, i.e. 60 minutes before and 60 minutes after drug administration, on day one and 2. At treatment end, parents and investigator gave an antitussive efficacy judgement. Tolerability was evaluated as per clinical evolution and laboratory parameters.

    Full Text Available We proposed to investigate subclinical cognitive impairment secondary to chronic Chagas' disease (CCD. No similar study was previously done. The neuropsychological performance of 45 chronic Chagasic patients and 26 matched controls (age, education place and years of residency in endemic area was compared using the Mini Mental State Exam (MMSE, Weschler Memory Scale (WMS and the Weschler Adult Intelligent Scale (WAIS. Non-parametric tests and Chi2 were used to compare group means and multivariate statistics in two way frequency tables for measures of independence and association of categorical variables with the disease. Results: Chagasic patients showed lower MMSE scores (p<004, poor orientation (p<.004, and attention (p<.007. Lower WMS MQ were associated with CCD (Chi2 5.9; p<.01; Fisher test p<.02.

The impairment in non-verbal reasoning, speed of information processing, problem solving, learning and sequencing observed in chronic Chagas disease patients resembles the cognitive dysfunction associated with white matter disease.

  13. Chronic Infection and Venous Thromboembolic Disease.

    Venous thromboembolic disease often arises as a complication of another pathological condition and/or triggering event. Infectious diseases result from both the direct action of the pathogens themselves and their effect on the immune system. The resulting inflammatory process and the coagulation and fibrinolysis processes share common pathways, explaining why infection is associated with thrombosis. In this brief overview, besides certain chronic infectious diseases, we also consider some acute infections, as the mechanisms are likely to be similar, particularly in the initial infective stage or the more acute episodes of a chronic infection. The infectious agent can be viral, bacterial, fungal, or parasitic. However, the literature on the link between infections and venous thromboembolism (VTE) is uneven, favoring infections that are found in more developed countries where physicians have access to VTE diagnostic tools. Thus, large epidemiological studies in this field are restricted to a limited number of the common chronic infectious diseases such as tuberculosis, while for other infections, particularly parasitic and fungal infections, the link with VTE is only evoked in a few scattered case reports.

    Feline calicivirus (FCV) is a major oral and respiratory pathogen of cats, able to induce subclinical infection as well as acute disease. It is also characterized by a high degree of antigenic variation. This work sought to address the question of the existence of distinct biotypes of FCV. Eight French, 6 British and 9 American FCV isolates, responsible for acute oral/respiratory disease or chronic gingivitis/stomatitis, were compared for their pathogenicity, antigenic profiles and serological relationships. Antigenic profiles were assessed by an indirect immunofluorescence assay with a large panel of characterized monoclonal antibodies. Cross-neutralisation assays were performed with specific cat antisera collected at 30 days p.i., then analysed by calculation of antigenic bilateral relatedness and dominance. Whatever their pathogenic origin, all the isolates induced an acute upper-respiratory tract infection in oronasally infected SPF kittens. Their antigenic profiles were different and did not correlate with their geographical or pathological origin. Cross-neutralisation studies and calculation of the mean bilateral relatedness allowed us to distinguish chronic original isolates from acute original ones. This study did not confirm the existence of FCV biotypes but showed that the chronic carrier state is related to the emergence of antigenically distant viruses.

    Introduction Asthma is one of the most frequently diagnosed respiratory diseases in the UK, and commonly co-occurs with other respiratory and allergic diseases, such as chronic obstructive pulmonary disease (COPD) and atopic dermatitis. Previous studies have shown an increased risk of lung cancer related to asthma, but the evidence is mixed when accounting for co-occurring respiratory diseases and allergic conditions. A systematic review of published data that investigate the relationship between asthma and lung cancer, accounting for co-occurring respiratory and allergic diseases, will be conducted to investigate the independent association of asthma with lung cancer. Methods and analysis A systematic review will be conducted, and include original reports of cohort, cross-sectional and case–control studies of the association of asthma with lung cancer after accounting for co-occurring respiratory diseases. Articles published up to June 2016 will be included, and their selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A standardised data extraction form will be developed and pretested, and descriptive analyses will be used to summarise the available literature. If appropriate, pooled effect estimates of the association between asthma and lung cancer, given adjustment for a specific co-occurring condition will be estimated using random effects models. Potential sources of heterogeneity and between study heterogeneity will also be investigated. Ethics and dissemination The study will be a review of published data and does not require ethical approval. Results will be disseminated through a peer-reviewed publication.

    Full Text Available Socioeconomic status (SES measured by educational and income levels has long been known to be associated with mortality from some diseases. Many studies from developed countries suggested that SES is associated with lung function and COPD exacerbation, prevalence and mortality. Socioeconomic disadvantage is an independent risk factor for COPD. The impact of low SES on respiratory disease in general has been attributed to poorer housing, more hazardous occupational exposure, poorer diet, a higher prevalence of smoking and respiratory infections in childhood. It was found that there was a significant negative correlation between lung function and SES. Childhood SES may influence pulmonary function in adulthood. Pulmonary functions decline earlier and faster for individual with lower childhood SES. It was reported that hospital admission rates for COPD in low SES group were higher than in the high SES group. There was not adequate data about relationship between SES and COPD in our country. [TAF Prev Med Bull 2013; 12(1.000: 87-96

    Sleep disorders have a profound and well-documented impact on overall health and quality of life in the general population. In patients with chronic disease, sleep disorders are more prevalent, with an additional morbidity and mortality burden. The complex and dynamic relationship between sleep disorders and chronic kidney disease (CKD) remain relatively little investigated. This article presents an overview of sleep disorders in patients with CKD, with emphasis on relevant pathophysiologic underpinnings and clinical presentations. Evidence-based interventions will be discussed, in the context of individual sleep disorders, namely sleep apnea, insomnia, restless leg syndrome and excessive daytime sleepiness. Limitations of the current knowledge as well as future research directions will be highlighted, with a final discussion of different conceptual frameworks of the relationship between sleep disorders and CKD.

    that renin inhibition could hold potential for improved treatment in patients with chronic kidney disease, with diabetic nephropathy as an obvious group of patients to investigate, as the activity of the renin-angiotensin-aldosterone system is enhanced in these patients and as there is an unmet need....... In addition, combination treatment seemed safe and effective also in patients with impaired kidney function. These initial findings formed the basis for the design of a large morbidity and mortality trial investigating aliskiren as add-on to standard treatment. The study has just concluded, but was terminated...... early as a beneficial effect was unlikely and there was an increased frequency of side effects. Also in non-diabetic kidney disease a few intervention studies have been carried out, but there is no ongoing hard outcome study. In this review we provide the current evidence for renin inhibition in chronic...

    Background. In the healthy liver there is a splanchnic net-uptake of lactate caused by gluconeogenesis. It has previously been shown that patients with acute liver failure in contrast have a splanchnic release of lactate caused by a combination of accelerated glycolysis in the splanchnic region...... and a reduction in hepatic gluconeogenesis. Aims. The aims of the present study were to investigate lactate metabolism and kinetics in patients with chronic liver disease compared with a control group with normal liver function. Methods. A total of 142 patients with chronic liver disease and 14 healthy controls...... underwent a liver vein catheterization. Blood samples from the femoral artery and the hepatic and renal veins were simultaneously collected before and after stimulation with galactose. Results. The fasting lactate levels, both in the hepatic vein and in the femoral artery, were higher in the patients than...

In addition to pulmonary manifestations, patients with COPD develop systemic problems, including skeletal muscle and other organ-specific dysfunctions, nutritional abnormalities, weight loss, and adverse psychological responses. Patients with COPD often complain of dyspnea on exertion, reduced exercise capacity, and develop a progressive decline in lung function with increasing age. These symptoms have been attributed to increases in the work of breathing and in impairments in gas exchange that result from airflow limitation and dynamic hyperinflation. However, there is mounting evidence to suggest that skeletal muscle dysfunction, independent of lung function, contributes significantly to reduced exercise capacity and poor quality of life in these patients. Limb and ventilatory skeletal muscle dysfunction in COPD patients has been attributed to a myriad of factors, including the presence of low grade systemic inflammatory processes, nutritional depletion, corticosteroid medications, chronic inactivity, age, hypoxemia, smoking, oxidative and nitrosative stresses, protein degradation and changes in vascular density. This review briefly summarizes the contribution of these factors to overall skeletal muscle dysfunction in patients with COPD, with particular attention paid to the latest advances in the field.Keywords: skeletal muscles, chronic obstructive pulmonary disease, diaphragm, quadriceps, fatigue, disuse, atrophy, smoking, exercise

  4. MICROBIOLOGICAL CHARACTERISATION OF Haemophilus influenzae STRAINS ISOLATED FROM PATIENTS WITH INVASIVE AND RESPIRATORY DISEASES

    Full Text Available A total of 175 H. influenzae strains were collected between 1994 and 2009 from all aged patient groups. The strains were isolated from patients with invasive and community-acquired respiratory tract infections. All strains were identified according to standard microbiological methods. Serotyping was done by a coagglutination test and by molecular PCR capsular genotyping. Beta-lactamase production was determined by the chromogenic cephalosporin test with nitrocephin as substrate. Most of the isolated H. influenzae strains were from children under 5 years of age (57.7%. Overall, 61 strains belonged to serotype b (34.9% by the means of PCR capsular typing, 1 strain was type f, and 113 isolates (64.6% were non-typeable (non-encapsulated H. influenzae. Among the infants and children with meningitis or other invasive infections, aged 2 month to 5 years, all strains, except one, were serotype b. In respiratory tract infections (pneumonia, otitis media, sinusitis and people with chronic pulmonary diseases - exacerbations of COPD, bronchiectasis, cystic fibrosis the most common - 96.5% were non-typeable strains in both groups children and adults. Overall, the prevalence of beta-lactamase production was 19.4%. But, it was much higher for invasive strains from CSF isolates - 37.7%, 25% in blood samples, and 37.5% in otitis media causative strains. Beta-lactamase production was less frequent in respiratory tract isolates - in sputum 13.3% and in URT samples - 2.3%. The rate of beta-lactamase production in CSF isolates has not changed for the last 10 years.PCR capsular genotyping method has to be performed for all non-b-type strains. The implementation of Hib vaccine in our country will be accompanied by a reduction in invasive diseases caused by H. influenzae type b in children, but it is not useful in preventing infections caused by non-typeable H. influenzae strains.

  5. Endocrinological disturbances in chronic obstructive pulmonary disease.

    Creutzberg, E C; Casaburi, R

    2003-11-01

    In this overview, the available literature on endocrinological disturbances in chronic obstructive pulmonary disease (COPD) is reviewed, with stress on growth hormone/insulin-like growth factor I (IGF-I), thyroid hormone and the anabolic steroids. In COPD, little is known about circulating growth hormone or IGF-I concentrations. Some authors find a decrease in growth hormone or IGF-I, others an increase. An increase of growth hormone might reflect a nonspecific response of the body to stress (for instance, hypoxaemia). Until now, only one controlled study on growth hormone supplementation has been published, which however did not reveal any functional benefits. Before growth hormone supplementation can be advised as part of the treatment in COPD, further controlled studies must be performed to investigate its functional efficacy. The prevalence of thyroid dysfunction in COPD and its role in pulmonary cachexia has not been extensively studied. So far, there is no evidence that thyroid function is consistently altered in COPD, except perhaps in a subgroup of patients with severe hypoxaemia. Further research is required to more extensively study the underlying mechanisms and consequences of disturbed thyroid function in this subgroup of COPD patients. A few studies have reported the results of anabolic steroid supplementation in chronic obstructive pulmonary disease. Although some studies have discerned that low circulating levels of testosterone are common in males with chronic obstructive pulmonary disease, little is known about the prevalence, the underlying causes or functional consequences of hypogonadism in these patients. The use of systemic glucocorticosteroids and an influence of the systemic inflammatory response have been suggested as contributing to low testosterone levels. It can be hypothesised that low anabolic hormones will reduce muscle mass and eventually result in a diminished muscle function. Further evidence is required before testosterone

    Coronary artery disease, hypertension, congestive heart failure, type 2 diabetes mellitus, osteoarthritis, osteoporosis, and cognitive disorders become more prevalent as people age. Besides delaying the onset of many of these conditions, regular exercise may improve function and delay disability and morbidity in those who have them. Further, exercise may work synergistically with medication to combat the effects of some chronic diseases. Special adaptations for older patients include lower-intensity exercise (eg, fewer repetitions), low-impact exercise (cycling, exercise while sitting), and modified equipment (smaller weights, special shoes, loose clothing). Unresolved issues include development of optimal strategies for motivating older patients to begin and maintain exercise programs.

The latest clinical trials to evaluate ivabradine’s efficacy have underlined its usefulness as a stand-alone medication and in combination with conventional congestive heart failure therapy, including in chronic kidney disease patients.

    Full Text Available Pulmonary lymphatic development in chronic lung disease (CLD has not been investigated, and anatomy of lymphatics in human infant lungs is not well defined. Hypothesis. Pulmonary lymphatic hypoplasia is present in CLD. Method. Autopsy lung tissues of eighteen subjects gestational ages 22 to 40 weeks with and without history of respiratory morbidity were stained with monoclonal antipodoplanin and reviewed under light microscopy. Percentage of parenchyma podoplanin stained at the acinar level was determined using computerized image analysis; 9 CLD and 4 control subjects gestational ages 27 to 36 weeks were suitable for the analysis. Results. Distinct, lymphatic-specific staining with respect to other vascular structures was appreciated in all gestations. Infants with and without respiratory morbidity had comparable lymphatic distribution which extended to the alveolar ductal level. Podoplanin staining per parenchyma was increased and statistically significant in the CLD group versus controls at the alveolar ductal level (0.06% ± 0.02% versus 0.04% ± 0.01%, 95% CI −0.04% to −0.002%, P<0.03. Conclusion. Contrary to our hypothesis, the findings show that there is an increase in alveolar lymphatics in CLD. It is suggested that the findings, by expanding current knowledge of CLD pathology, may offer insight into the development of more effective therapies to tackle CLD.

    Tortoise mycoplasmosis is one of the most extensively characterized infectious diseases of chelonians. A 1989 outbreak of upper respiratory tract disease (URTD) in free-ranging Agassiz's desert tortoises (Gopherus agassizii) brought together an investigative team of researchers, diagnosticians, pathologists, immunologists and clinicians from multiple institutions and agencies. Electron microscopic studies of affected tortoises revealed a microorganism in close association with the nasal mucosa that subsequently was identified as a new species, Mycoplasma agassizii. Over the next 24 years, a second causative agent, Mycoplasma testudineum, was discovered, the geographic distribution and host range of tortoise mycoplasmosis were expanded, diagnostic tests were developed and refined for antibody and pathogen detection, transmission studies confirmed the pathogenicity of the original M. agassizii isolate, clinical (and subclinical) disease and laboratory abnormalities were characterized, many extrinsic and predisposing factors were found to play a role in morbidity and mortality associated with mycoplasmal infection, and social behavior was implicated in disease transmission. The translation of scientific research into management decisions has sometimes led to undesirable outcomes, such as euthanasia of clinically healthy tortoises. In this article, we review and assess current research on tortoise mycoplasmosis, arguably the most important chronic infectious disease of wild and captive North American and European tortoises, and update the implications for management and conservation of tortoises in the wild.

  15. Respirable antisense oligonucleotides: a new drug class for respiratory disease

    Full Text Available Abstract Respirable antisense oligonucleotides (RASONs, which attenuate specific disease-associated mRNAs, represent a new class of respiratory therapeutics with considerable potential. RASONs overcome previous obstacles that have impeded the development of antisense therapeutics targeting diseases in other organ systems. RASONs are delivered directly to the target tissue via inhalation; their uptake seems to be enhanced by cationic properties inherent in pulmonary surfactant, and, because of the markedly different target properties of mRNA and proteins, they can have very long durations of effect compared with traditional drugs targeting the protein of the same gene. RASONs contain chemical modifications that decrease their degradation by cellular nucleases. However, total insensitivity to nucleases is probably not an optimal design criterion for RASONs, because moderate nuclease sensitivity can prevent their systemic delivery, decreasing the potential for systemic toxicity. EPI-2010 is a 21-mer phosphorothioate RASON that attenuates bronchoconstriction, inflammation and surfactant depletion in preclinical models of human asthma, has a duration of effect of seven days, and seems to undergo minimal systemic delivery.

  16. New drugs for exacerbations of chronic obstructive pulmonary disease.

    2009-08-29

    Tobacco smoking is the dominant risk factor for chronic obstructive pulmonary disease (COPD), but viral and bacterial infections are the major causes of exacerbations in later stages of disease. Reactive oxygen species (ROS), pathogen-associated molecular patterns (PAMPs), and damage-associated molecular patterns (DAMPs) activate families of pattern recognition receptors (PRRs) that include the toll-like receptors (TLRs). This understanding has led to the hypothesis that COPD is an archetypal disease of innate immunity. COPD is characterised by abnormal response to injury, with altered barrier function of the respiratory tract, an acute phase reaction, and excessive activation of macrophages, neutrophils, and fibroblasts in the lung. The activated non-specific immune system then mediates the processes of inflammation and repair, fibrosis, and proteolysis. COPD is also associated with corticosteroid resistance, abnormal macrophage and T-cell populations in the airway, autoinflammation and autoimmunity, aberrant fibrosis, accelerated ageing, systemic and concomitant disease, and defective regeneration. Such concepts have been used to generate a range of molecular targets, and clinical trials are taking place to identify effective drugs for the prevention and treatment of COPD exacerbations.

    Full Text Available There is some evidence indicating the role of Helicobacter pylori infection in pathogenesis of extragastrointestinal diseases including skin, vascular, and autoimmune disorders, as well as some respiratory diseases. The aim of this study was to investigate the association between H. pylori and chronic obstructive pulmonary disease (COPD. In a case-control study, 90 patients with COPD and 90 age- and sex- matched control subjects were included. Serum samples were tested for anti-H. pylori and anti-CagA IgG by ELISA. A physician completed a questionnaire including demographic characteristics, habitual history, and spirometric findings for each patient. Of 90 patients with COPD 66 (51% had mild, 31 (34.4% moderate, and 13 (14.4% sever disease. There was no significant association between H. pylori IgG seropositivity and COPD. Serum levels of anti-CagA IgG were significantly higher in patients with COPD than in the control subjects (P < 0.001. No association was observed between H. pylori infection and severity of COPD. The results suggest that there is an association between CagA-positive H. pylori infections and COPD. Further studies should be planned to investigate the potential pathogenic mechanisms that might underlie these associations.

    Chronic beryllium disease (CBD) is a granulomatous lung disease that may be pathologically and clinically indistinguishable from pulmonary sarcoidosis, except through use of immunologic testing, such as the beryllium lymphocyte proliferation test (BeLPT). Similar to sarcoidosis, the pulmonary manifestations of CBD are variable and overlap with other respiratory diseases. Definitive diagnosis of CBD is established by evidence of immune sensitization to beryllium and diagnostic bronchoscopy with bronchoalveolar lavage and transbronchial biopsy. However, the diagnosis of CBD can also be established on a medically probable basis in beryllium-exposed patients with consistent radiographic imaging and clinical course. Beryllium workers exposed too much higher levels of beryllium in the past demonstrated a much more fulminant disease than is usually seen today. Some extrapulmonary manifestations similar to sarcoidosis were noted in these historic cohorts, although with a narrower spectrum. Extrapulmonary manifestations of CBD are rare today. Since lung-predominant sarcoidosis can very closely resemble CBD, CBD is still misdiagnosed as sarcoidosis when current or past exposure to beryllium is not recognized and no BeLPT is obtained. This article describes the similarities and differences between CBD and sarcoidosis, including clinical and diagnostic features that can help physicians consider CBD in patients with apparent lung-predominant sarcoidosis.

    2008-01-01

    A structured literature review was performed to detail the frequency and etiology of chronic liver disease (CLD) in Aboriginal North Americans. CLD affects Aboriginal North Americans disproportionately and is now one of the most common causes of death.Alcoholic liver disease is the leading etiology of CLD,but viral hepatitis, particularly hepatitis C, is an important and growing cause of CLD. High rates of autoimmune hepatitis and primary biliary cirrhosis (PBC) are reported in regions of coastal British Columbia and southeastern Alaska. Non-alcoholic liver disease is a common, but understudied, cause of CLD.Future research should monitor the incidence and etiology of CLD and should be geographically inclusive.In addition, more research is needed on the treatment of hepatitis C virus (HCV) infection and non-alcoholicfatty liver disease (NAFLD) in this population.

    2015-05-01

    Bactericidal/permeability-increasing protein fold-containing family member A1 (BPIFA1), formerly known as SPLUNC1, is one of the most abundant proteins in respiratory secretions and has been identified with increasing frequency in studies of pulmonary disease. Its expression is largely restricted to the respiratory tract, being highly concentrated in the upper airways and proximal trachea. BPIFA1 is highly responsive to airborne pathogens, allergens, and irritants. BPIFA1 actively participates in host protection through antimicrobial, surfactant, airway surface liquid regulation, and immunomodulatory properties. Its expression is modulated in multiple lung diseases, including cystic fibrosis, chronic obstructive pulmonary disease, respiratory malignancies, and idiopathic pulmonary fibrosis. However, the role of BPIFA1 in pulmonary pathogenesis remains to be elucidated. This review highlights the versatile properties of BPIFA1 in antimicrobial protection and its roles as a sensor of environmental exposure and regulator of immune cell function. A greater understanding of the contribution of BPIFA1 to disease pathogenesis and activity may clarify if BPIFA1 is a biomarker and potential drug target in pulmonary disease.

    Full Text Available Abstract Africa faces a double burden of infectious and chronic diseases. While infectious diseases still account for at least 69% of deaths on the continent, age specific mortality rates from chronic diseases as a whole are actually higher in sub Saharan Africa than in virtually all other regions of the world, in both men and women. Over the next ten years the continent is projected to experience the largest increase in death rates from cardiovascular disease, cancer, respiratory disease and diabetes. African health systems are weak and national investments in healthcare training and service delivery continue to prioritise infectious and parasitic diseases. There is a strong consensus that Africa faces significant challenges in chronic disease research, practice and policy. This editorial reviews eight original papers submitted to a Globalization and Health special issue themed: "Africa's chronic disease burden: local and global perspectives". The papers offer new empirical evidence and comprehensive reviews on diabetes in Tanzania, sickle cell disease in Nigeria, chronic mental illness in rural Ghana, HIV/AIDS care-giving among children in Kenya and chronic disease interventions in Ghana and Cameroon. Regional and international reviews are offered on cardiovascular risk in Africa, comorbidity between infectious and chronic diseases and cardiovascular disease, diabetes and established risk factors among populations of sub-Saharan African descent in Europe. We discuss insights from these papers within the contexts of medical, psychological, community and policy dimensions of chronic disease. There is an urgent need for primary and secondary interventions and for African health policymakers and governments to prioritise the development and implementation of chronic disease policies. Two gaps need critical attention. The first gap concerns the need for multidisciplinary models of research to properly inform the design of interventions. The second

    Although chronic obstructive pulmonary disease (COPD) is characterized by poorly reversible, chronic airflow obstruction, from the clinical point of view we must continue to make progress in the diagnosis and management of these patients so that spirometry is not the only technique used. Understanding that COPD is a heterogeneous process and that patient complexity usually increases due to the presence of comorbidities will allow more individualized strategies to be designed, which may improve control of the process. The TORCH and UPLIFT trials have shown that current treatment can improve important aspects of the disease, including mortality. However, the finalizing of these two large trials has generated a current of opinion favoring a more individually-tailored approach that should include all the factors -both pulmonary and extrapulmonary- that can modify the patient's form of presentation. Although we are witnessing a change in the therapeutic approach to COPD, future treatment will probably be based on studies performed in specific patient subgroups and on clarifying the interrelation between COPD and other diseases that are common in these patients. Greater knowledge of the pathogenesis of the disease may improve pharmacological treatment but drugs that, by themselves, alter the short- and longterm course of COPD are not on the horizon. However, a more patient-focussed approach may be the main tool available to physicians to increase quality of life -and possibly survival- in these patients.

    Vitamin D is an important secosteroid hormone with known effect on calcium homeostasis,but recently there is increasing recognition that vitamin D also is involved in cell proliferation and differentiation,has immunomodulatory and anti-inflammatory properties.Vitamin D deficiency has been frequently reported in many causes of chronic liver disease and has been associated with the development and evolution of non-alcoholic fatty liver disease(NAFLD)and chronic hepatitis C(CHC)virus infection.The role of vitamin D in the pathogenesis of NAFLD and CHC is not completely known,but it seems that the involvement of vitamin D in the activation and regulation of both innate and adaptive immune systems and its antiproliferative effect may explain its importance in these liver diseases.Published studies provide evidence for routine screening for hypovitaminosis D in patients with liver disease.Further prospectives studies demonstrating the impact of vitamin D replacement in NAFLD and CHC are required.

  8. Role of cannabinoids in chronic liver diseases

    2008-01-01

    Cannabinoids are a group of compounds acting primarily via CB1 and CB2 receptors. The expression of cannabinoid receptors in normal liver is low or absent. However, many reports have proven up-regulation of the expression of CB1 and CB2 receptors in hepatic myofibroblasts and vascular endothelial cells, as well as increased concentration of endocannabinoids in liver in the course of chronic progressive liver diseases. It has been shown that CB1 receptor signalling exerts profibrogenic and proinflammatory effects in liver tissue, primarily due to the stimulation of hepatic stellate cells, whereas the activation of CB2 receptors inhibits or even reverses liver fibrogenesis. Similarly, CB1 receptor stimulation contributes to progression of liver steatosis. In end-stage liver disease, the endocannabi-noid system has been shown to contribute to hepatic encephalopathy and vascular effects, such as portal hypertension, splanchnic vasodilatation, relative pe-ripheral hypotension and probably cirrhotic cardiomy-opathy. So far, available evidence is based on cellular cultures or animal models. Clinical data on the effects of cannabinoids in chronic liver diseases are limited. However, recent studies have shown the contribution of cannabis smoking to the progression of liver fibrosis and steatosis. Moreover, controlling CB1 or CB2 signal-ling appears to be an attractive target in managing liver diseases.

    This research assessed: 1) whether patients thought to have sleep disordered breathing would have more severe symptoms if they were taking opioids; 2) whether severity of sleep disordered breathing was associated with class or dose of opioid; and 3) whether pain intensity was associated with sleep disordered breathing. A descriptive cross-sectional study of patients referred for assessment of sleep disorders was conducted. Data were collected on a total of 419 subjects (no pain [n = 171], chronic pain without opioid treatment [n = 187], and chronic pain with opioid treatment [n = 61]). The findings suggest that regardless of opioid drug or dose, the management of chronic pain with opioids is not likely to exacerbate obstructive sleep apnea at stable doses. However, central sleep apnea was associated with opioid use. Patients with chronic pain taking opioids had a mean of 5 ± 13 central apneic events per hour compared with 1.6 ± 7 events per hour in patients without pain and not taking opioids. Oxygen saturation mean nadir 83.5% (opioid group) versus 82.9% (no pain, pain without opioid) was not significantly different. The clinical relevance of the effect is unknown, so the potential for marginal respiratory disturbance (an increase of 2.8 central events per hour for every 100 mg morphine-equivalent opioid dose) must be weighed against the therapeutic value of pain management with opioids.

    This article is the summary of a workshop, which took place in November 2013, on the roles of microorganisms in chronic respiratory diseases. Until recently, it was assumed that lower airways were sterile in healthy individuals. However, it has long been acknowledged that microorganisms could be identified in distal airway secretions from patients with various respiratory diseases, including cystic fibrosis (CF) and non-CF bronchiectasis, chronic obstructive pulmonary disease, asthma and other chronic airway diseases (e.g. post-transplantation bronchiolitis obliterans). These microorganisms were sometimes considered as infectious agents that triggered host immune responses and contributed to disease onset and/or progression; alternatively, microorganisms were often considered as colonisers, which were considered unlikely to play roles in disease pathophysiology. These concepts were developed at a time when the identification of microorganisms relied on culture-based methods. Importantly, the majority of microorganisms cannot be cultured using conventional methods, and the use of novel culture-independent methods that rely on the identification of microorganism genomes has revealed that healthy distal airways display a complex flora called the airway microbiota. The present article reviews some aspects of current literature on host-microbe (mostly bacteria and viruses) interactions in healthy and diseased airways, with a special focus on distal airways.

    Upper respiratory tract disease (URTD) caused by Mycoplasma agassizii is considered a threat to desert tortoise populations that should be addressed as part of the recovery of the species. Clinical signs can be intermittent and include serous or mucoid nasal discharge and respiratory difficulty when nares are occluded. This nasal congestion may result in a loss of the olfactory sense. Turtles are known to use olfaction to identify food items, predators, and conspecifics; therefore, it is likely that URTD affects not only their physical well-being but also their behavior and ability to perform necessary functions in the wild. To determine more specifically the impact nasal discharge might have on free-ranging tortoises (Gopherus agassizii), we compared the responses of tortoises with and without nasal discharge and both positive and negative for M. agassizii antibodies to a visually hidden olfactory food stimulus and an empty control. We found that nasal discharge did reduce sense of smell and hence the ability to locate food. Our study also showed that moderate chronic nasal discharge in the absence of other clinical signs did not affect appetite in desert tortoises.

    Full Text Available It is extensively verified that continued oxidative stress and oxidative damage may lead to chronic inflammation, which in turn can mediate most chronic diseases including cancer, diabetes, cardiovascular, neurological, inflammatory bowel disease and pulmonary diseases. Curcumin, a yellow coloring agent extracted from turmeric, shows strong anti-oxidative and anti-inflammatory activities when used as a remedy for the prevention and treatment of chronic diseases. How oxidative stress activates inflammatory pathways leading to the progression of chronic diseases is the focus of this review. Thus, research to date suggests that chronic inflammation, oxidative stress, and most chronic diseases are closely linked, and the antioxidant properties of curcumin can play a key role in the prevention and treatment of chronic inflammation diseases.

Curcumin, a yellow coloring agent extracted from turmeric, shows strong anti-oxidative and anti-inflammatory activities when used as a remedy for the prevention and treatment of chronic diseases. How oxidative stress activates inflammatory pathways leading to the progression of chronic diseases is the focus of this review. Thus, research to date suggests that chronic inflammation, oxidative stress, and most chronic diseases are closely linked, and the antioxidant properties of curcumin can play a key role in the prevention and treatment of chronic inflammation diseases.

    Chronic kidney disease (CKD) is highly prevalent and has major health consequences for patients. Caring for patients with CKD requires knowledge of the food supply, renal pathophysiology, and nutrition-related medications used to work synergistically with diet to control the signs and symptoms of the disease. The nutrition care process and International Dietetic and Nutrition Terminology allow for systematic, holistic, quality care of patients with this complex, progressive disease. Nutrition interventions must be designed with the individual patients needs in mind while prioritizing factors with the largest negative impact on health outcomes and mortality risk. New areas of nutrition treatment are emerging that involve a greater focus on micronutrient needs, the microbiome, and vegetarian-style diets. These interventions may improve outcomes by decreasing inflammation, improving energy and protein delivery, and lowering phosphorus, electrolytes, and fluid retention.

    Chronic kidney disease and diabetes mellitus represent a worldwide public health problem. The incidence of these diseases is gradually growing into epidemic proportions. In many cases they occur simultaneously, what leads to increased morbidity and mortality among the affected patients. The majority of the patients treated for diabetes mellitus are unaware of the presence of renal insufficiency. Vascular hypertrophy and diabetic kidney disease in patients with type 2 diabetes are the most common causes of kidney failure in countries with advanced healthcare systems. Metformin is a basic drug used for the treatment of type 2 diabetes mellitus. It is excreted in an unchanged form by the kidneys. When administered to patients with renal insufficiency, sepsis, dehydration or after the parenteral administration of iodinated contrast agents, metformin can cause lactic acidosis, which is also associated with an increased mortality rate.

    Chronic kidney disease-related mineral and bone disease (CKD-MBD) is a syndrome defined as a systemic mineral metabolic disorder associated with CKD, and the term renal osteodystrophy indicates a pathomorphological concept of bone lesions associated with CKD-MBD. Cortical bone thinning, abnormalities in bone turnover and primary/secondary mineralization, elevated levels of circulating sclerostin, increased apoptosis in osteoblasts and osteocytes, disturbance of the coupling phenomenon, iatrogenic factors, accumulated micro-crackles, crystal/collagen disorientation, and chemical modification of collagen crosslinks are all possible candidates found in CKD that could promote osteopenia and/or bone fragility. Some of above factors are the consequences of abnormal systemic mineral metabolism but for others it seem unlikely. We have used the term uremic osteoporosis to describe the uremia-induced bone fragility which is not derived from abnormal systemic mineral metabolism. Interestingly, the disease aspect of uremic osteoporosis appears to be similar to that of senile osteoporosis.

    Chronic granulomatous disease (CGD) is a primary immunodeficiency caused by a defect in production of phagocyte-derived reactive oxygen species, which leads to recurrent infections with a characteristic group of pathogens not previously known to include methylotrophs. Methylotrophs are versatile environmental bacteria that can use single-carbon organic compounds as their sole source of energy; they rarely cause disease in immunocompetent persons. We have identified 12 infections with methylotrophs (5 reported here, 7 previously reported) in patients with CGD. Methylotrophs identified were Granulibacter bethesdensis (9 cases), Acidomonas methanolica (2 cases), and Methylobacterium lusitanum (1 case). Two patients in Europe died; the other 10, from North and Central America, recovered after prolonged courses of antimicrobial drug therapy and, for some, surgery. Methylotrophs are emerging as disease-causing organisms in patients with CGD. For all patients, sequencing of the 16S rRNA gene was required for correct diagnosis. Geographic origin of the methylotroph strain may affect clinical management and prognosis.

    Concepts relating to the natural history of chronic obstructive pulmonary disease (COPD) arise most importantly from the classic study of Fletcher and colleagues (The Natural History of Chronic Bronchitis and Emphysema, Oxford University Press, New York, 1976). This study, which evaluated working...... English men over 8 years, was used to construct a proposed life-long natural history. Although this is a classic study that has greatly advanced understanding of COPD, it has a number of limitations. Its duration is relatively short compared with the duration of COPD, so it is more cross-sectional than...... longitudinal. It was unable to distinguish among varied "natural histories." It assessed primarily the FEV(1), and the natural history of other features of COPD is largely undescribed. With advances in understanding the clinical features of COPD and with the development of evaluating new tools to assess...

Nevertheless, falls are associated to increased mortality, decreased independence and physical activity levels, and worsening of quality of life. The aims of this systematic review was to evaluate information in the literature with regard to whether impaired postural control is more prevalent in COPD patients than in healthy age-matched subjects, and to assess the main characteristics these patients present that contribute to impaired postural control.Methods: Five databases were searched with no dates or language limits. The MEDLINE, PubMed, EMBASE, Web of Science, and PEDro databases were searched using “balance”, “postural control”, and “COPD” as keywords. The search strategies were oriented and guided by a health science librarian and were performed on March 27, 2014. The studies included were those that evaluated postural control in COPD patients as their main outcome and scored more than five points on the PEDro scale. Studies supplied by the database search strategy were assessed independently by two blinded researchers.Results: A total of 484 manuscripts were found using the “balance in COPD or postural control in COPD” keywords. Forty-three manuscripts appeared more than once, and 397 did not evaluate postural control in COPD patients as the primary outcome. Thus, only 14 studies had postural control as their primary outcome. Our study

  2. Sleep-related disorders in chronic obstructive pulmonary disease.

    Sleep may have several negative consequences in patients with chronic obstructive pulmonary disease (COPD). Sleep is typically fragmented with diminished slow wave and rapid-eye-movement sleep, which likely represents an important contributing factor to daytime symptoms such as fatigue and lethargy. Furthermore, normal physiological adaptations during sleep, which result in mild hypoventilation in normal subjects, are more pronounced in COPD, which can result in clinically important nocturnal oxygen desaturation. The co-existence of obstructive sleep apnea and COPD is also common, principally because of the high prevalence of each disorder, and there is little convincing evidence that one disorder predisposes to the other. Nonetheless, this co-existence, termed the overlap syndrome, typically results in more pronounced nocturnal oxygen desaturation and there is a high prevalence of pulmonary hypertension in such patients. Management of sleep disorders in patients with COPD should address both sleep quality and disordered gas exchange. Non-invasive pressure support is beneficial in selected cases, particularly during acute exacerbations associated with respiratory failure, and is particularly helpful in patients with the overlap syndrome. There is limited evidence of benefit from pressure support in the chronic setting in COPD patients without obstructive sleep apnea.

    Aim. The paper gives a theoretical account of experiences of assisted personal body care (APBC) in hospitalized patients with severe chronic obstructive pulmonary disease (COPD). Background. Body care has been identified as a central but underestimated area of nursing. Hospitalized patients...... with severe COPD suffer from breathlessness on exertion and are dependent on help with personal body care. Studies have described patient strategies for managing breathlessness and preferences regarding nursing care during hospitalization. Yet the problems that patients can experience because....... Dependency and breathlessness, however, impeded the performance of body care activities and patients were struggling for self-preservation. They managed APBC by using a threefold strategy of not letting go, coping with dependency, and minimizing the risk of escalating breathlessness. Two dilemmas were...
