A three-primer PCR assay was designed for detection of possible deletions in the RD7 region of the Mycobacterium tuberculosis complex chromosome. The assay produced amplicons of different size depending on the presence or absence of the deletions. The PCR assay was applied to 176 isolates from patients with lung tuberculosis collected in different areas of Kazakhstan in summer 2004. The isolates were initially characterized by culture and biochemical tests. The RD7 genotyping results demonstrated no polymorphism and the absence of deletions in the RD7 genome region. Some strains were additionally characterized using PCR-RFLP analysis of gyrB and hsp64 genes. The RFLP-patterns obtained corresponded to the M. tuberculosis genotypes. The results of this work are consistent with certain previous studies, indicating population stability of the RD7 region in M. tuberculosis strains. Species characterization of the isolates shows that M. tuberculosis sensu stricto is the principal causative agent of human lung tuberculosis in Kazakhstan.

Full Text Available We prospectively followed-up new patients of tuberculosis while on maintenance hemodialysis at a State Government-run tertiary care institute. Between 2000 and 2010, 1237 new patients were initiated on maintainence hemodialysis. The number of patients diagnosed with tuberculosis after initiation of hemodialysis was 131 (10.5% of 1237. The age was 46.4 ± 10.4 (range 8-85 years and there were 90 (68.7% males. The number of patients diagnosed with tuberculosis on the basis of organ involvement were: Pulmonary-60, pleural effusion-31, lymph node-21, meningitis-8, pericardial effusion-7, peritoneum-2, latent tuberculosis-2. The incidence of tuberculosis in hemodialysis was found to be 105.9 per 1000 patient years. Male gender, diabetes mellitus, past history of tuberculosis, mining as an occupation, low serum albumin, and duration of hemodialysis more than 24 months, and unemployment were found to be significant risk-factors on univariate analysis.

Vitamins are known to be associated with immunity and nutrition. Moreover, vitamin deficiency can affect host immunity to various infectious diseases, including tuberculosis. Although patients with tuberculosis often have vitamin D deficiency, little is known about the levels of other vitamins. Here, we aimed to investigate the status of vitamins A, B 12 , D, and E in patients with tuberculosis. We also aimed to investigate the clinical and laboratory variables related to vitamin status in patients with tuberculosis. We performed a case-control study to investigate the serum vitamin concentrations in 152 patients with tuberculosis and 137 control subjects. The concentrations of vitamin A, vitamin D, vitamin E, homocysteine, and methylmalonic acid were measured using high-performance liquid chromatography (HPLC) or HPLC-tandem mass spectrometry. Patient demographic data and other biochemical parameters were also analyzed. The serum concentrations of vitamins A, D, and E were significantly lower in patients with tuberculosis than in control subjects (1.4 vs. 2.0 μmol/L, P vitamin deficiencies were significantly higher in patients with tuberculosis. Moreover, multiple vitamin deficiencies were only observed in patients with tuberculosis (22.4% of all patients with tuberculosis vs. 0% of all control subjects). Positive correlations among vitamin A, D, and E concentrations were observed (vitamins A and D, r = 0.395; vitamins D and E, r = 0.342; and vitamins A and E, r = 0.427, P vitamin A, D, and E concentrations. Vitamin deficiencies are common in patients with tuberculosis. Further research investigating the clinical importance of vitamin and nutritional status in patients with tuberculosis is needed.

Full Text Available Tuberculosis is a very important problem for public health all around the world. In this study, 168 patients with TB who were treated in Batman Tuberculosis Control Dispensary in 2003 were retrospectively assessed. Ninety six of our cases were male, 72 were female. Eighty one patients who underwent for the tuberculous treatment were with pulmonary tuberculosis and 87 cases were with extrapulmonary tuberculosis. Acid fast bacilli (AFB at sputum was positive in 66.17% of the cavitary pulmonary TB cases before treatment and only one patient’s sputum was positive in pulmonary tuberculosis without cavity. Results of the tuberculosis treatment of cases revealed that one case left the treatment, 3 patients were inharmonious, 3 patients were dead, 161 patients were cured. Success rate of treatment was 95,83% (5 of these cases were cured and 156 patients completed the treatment. These data suggest that in order to increase the rate of the cure, bacteriological examination of the sputum should be considered at the end of the treatment like as the beginning.

2012-01-01

Background An increasing number of studies have implicated the microbiome in certain diseases, especially chronic diseases. In this study, the bacterial communities in the sputum of pulmonary tuberculosis patients were explored. Total DNA was extracted from sputum samples from 31 pulmonary tuberculosis patients and respiratory secretions of 24 healthy participants. The 16S rRNA V3 hyper-variable regions were amplified using bar-coded primers and pyro-sequenced using Roche 454 FLX. Results The results showed that the microbiota in the sputum of pulmonary tuberculosis patients were more diverse than those of healthy participants (ppulmonary tuberculosis patients and 17 of which were found in healthy participants. Furthermore, many foreign bacteria, such as Stenotrophomonas, Cupriavidus, Pseudomonas, Thermus, Sphingomonas, Methylobacterium, Diaphorobacter, Comamonas, and Mobilicoccus, were unique to pulmonary tuberculosis patients. Conclusions This study concluded that the microbial composition of the respiratory tract of pulmonary tuberculosis patients is more complicated than that of healthy participants, and many foreign bacteria were found in the sputum of pulmonary tuberculosis patients. The roles of these foreign bacteria in the onset or development of pulmonary tuberculosis shoud be considered by clinicians. PMID:23176186

Sarcoidosis and tuberculosis closely resemble each other and Mycobacterium tuberculosis has been implicated as a causative agent for sarcoidosis. Herein we explore the socio-demographic features of patients with sarcoidosis vis-a-vis tuberculosis. In a prospective case-control design, we studied hundred patients each of newly diagnosed sarcoidosis, bacteriologically confirmed pulmonary tuberculosis and healthy controls. Socio-demographic profile was recorded on a standardized questionnaire. Information about tobacco smoking, exposure to environmental tobacco smoke (ETS) and cooking fuels was also collected. Various parameters were compared among the three groups. Compared to tuberculosis, patients with sarcoidosis were elder, had better body mass index (BMI), higher urban residence (OR 2.19, 95% CI: 1.02-4.69), were better educated (ORs 8.50 to 74.25 for different categories), had higher per capita income (OR 13.33; 95% CI: 6.79-26.19) and belonged to better overall socio-economic status (SES) (ORs 8.57-195.0 for different categories). All these differences were also significant when sarcoidosis patients were compared to healthy controls albeit to a lesser degree. Tobacco smoking, ETS exposure and use of fossil/biomass fuels for cooking were more commonly seen in TB patients. In the multivariate analysis, as compared to TB or controls, sarcoidosis patients had higher odds for a better SES after adjusting for age, gender, BMI, religion, smoking, ETS exposure and cooking fuel. Patients with sarcoidosis are likely to be better educated and more affluent compared to those with tuberculosis and healthy controls and this can be useful in clinical differential diagnosis of the two conditions in populations with high prevalence of TB.

Full Text Available Aim: Abdominal tuberculosis is an uncommon form of extrapulmonary infection. In this study, we aimed to highlight the nonspecific clinical presentations and diagnostic difficulties of abdominal tuberculosis. Material and Method: Clinical features, diagnostic methods, and the therapeutic outcomes of 49 patients diagnosed as abdominal tuberculosis between 2003 and 2014 were retrospectively analyzed. Results: The patients were classified into four subgroups including peritoneal (28, nodal (14, intestinal (5, and solid organ tuberculosis (2. The most frequent symptoms were abdominal pain, abdominal distention and fatique. Ascites appeared to be the most frequent clinical finding. Ascites and enlarged abdominal lymph nodes were the most frequent findings on ultrasonography and tomography. Diagnosis of abdominal tuberculosis was mainly depended on histopathology of ascitic fluid and biopsies from peritoneum, abdominal lymph nodes or colonoscopic materials. Forty patients healed with standart 6-month therapy while extended treatment for 9-12 months was needed in 8 whom had discontinued drug therapy and had persistent symptoms and signs. One patient died within the treatment period due to disseminated infection. Discussion: The diagnosis of abdominal tuberculosis is often difficult due to diverse clinical presentations. The presence of ascites, personal/familial/contact history of tuberculosis, and coexisting active extraabdominal tuberculosis are the most significant marks in diagnosis. Diagnostic laparoscopy and tissue sampling seem to be the best diagnostic approach for abdominal tuberculosis.

The aim of the search was investigation of tuberculosis in AIDS patients. Each year 8-9 mln people fall ill of tuberculosis and one third of them die. To the infection of tuberculosis and fast development into active state are especially exposed people with AIDS. 696 people were examined on tuberculosis most of which were AIDS patients hospitalized and cured in Hospital of Infection Diseases and Prison Hospital. 159 patients were women and 537 were men. The average age was between 25 and 45 (70%). The investigated population was characterized according to age, social and living conditions, using drugs and former contact with tuberculosis. All patients suspected of tuberculosis had chest X-rayed, sputum, BAL and pleural liquor were taken to bacteriological examination when extrapulmonary tuberculosis was suspected. The material was taken adequately to the disease process: CSF, urine, lymph nodes, peritoneal fluids, blood, stool, swabs and other. Bacteriological investigations have been carried out by fast cultivating method since 1998 and rapid genetic method since 1999. Apart from modern, fast diagnostic methods, routine bacteriological procedures were applied in tuberculosis diagnosis. More than 30% of the examined population were from bad social-living conditions, 78% had risk factors, 65% were drug users. The analysis of the tuberculosis illness from 1997 to July 2001 shows growing tendency. Nowadays it is 20% cases proved by bacteriological diagnosis. The structure of falling ill with tuberculosis has changed. Considerable increase of extrapulmonary tuberculosis was observed, 20 patients died due to tuberculosis and 8 patients due to mycobacteriosis. Resistance of M.tub.complex occurred within the range of 10% cases.

Coinfection with tuberculosis in some countries occurs in 8–15% of human immunodeficiency virus (HIV) -infected patients who have histoplasmosis. This coinfection interferes with prompt diagnosis, and treatment is difficult because of drug interactions. We retrospectively reviewed the cases of 14 HIV-infected patients who had concomitant tuberculosis and histoplasmosis. The most frequent clinical manifestations were weight loss (85.7%), asthenia (78.5%), and fever (64.2%). The diagnosis of histoplasmosis was made primarily by histopathology (71.4%), and the diagnosis of tuberculosis was made by means of direct microscopic examination (71.4%). Death occurred in two patients, and relapse of both infections occurred in one patient. Moxifloxacin was substituted for rifampicin in six patients, with good outcomes noted for both infections. The clinical presentation does not readily identify acquired immunodeficiency syndrome (AIDS) patients who have tuberculosis and histoplasmosis. The use of a fluoroquinolone as an alternative agent in place of rifampicin for tuberculosis allows effective therapy with itraconazole for histoplasmosis. PMID:23128292

Full Text Available Abstract Background More than 1 million tuberculosis (TB patients are receiving the standard anti-TB treatment provided by China National Tuberculosis Prevention and Control Scheme (CNTS in China every year. Adverse reactions (ADRs induced by anti-TB drugs could both do harm to patients and lead to anti-TB treatment failure. The ADACS aimed to explore ADRs' incidences, prognoses, economical and public health impacts for TB patients and TB control, and build a DNA bank of TB patients. Methods/Design Multiple study designs were adopted. Firstly, a prospective cohort with 4488 sputum smears positive pulmonary tuberculosis patients was established. Patients were followed up for 6-9 months in 52 counties of four regions. Those suspected ADRs should be checked and confirmed by Chinese State Food and Drug Administration (SFDA. Secondly, if the suspected ADR was anti-TB drug induced liver injury (ATLI, a nested case-control study would be performed which comprised choosing a matched control and doing a plus questionnaire inquiry. Thirdly, health economical data of ADRs would be collected to analyze financial burdens brought by ADRs and cost-effectiveness of ADRs' treatments. Fourthly, a drop of intravenous blood for each patient was taken and saved in FTA card for DNA banking and genotyping. Finally, the demographic, clinical, environmental, administrative and genetic data would be merged for the comprehensive analysis. Discussion ADACS will give an overview of anti-TB drugs induced ADRs' incidences, risk factors, treatments, prognoses, and clinical, economical and public health impacts for TB patients applying CNTS regimen in China, and provide suggestions for individualized health care and TB control policy.

Full Text Available One-third of the world's population has been infected with Mycobacterium tuberculosis (M. tuberculosis, a primary pathogen of the mammalian respiratory system, while about 10% of latent infections progress to active tuberculosis (TB, indicating that host and environmental factors may determine the outcomes such as infection clearance/persistence and treatment prognosis. The gut microbiota is essential for development of host immunity, defense, nutrition and metabolic homeostasis. Thus, the pattern of gut microbiota may contribute to M. tuberculosis infection and prognosis. In current study we characterized the differences in gut bacterial communities in new tuberculosis patients (NTB, recurrent tuberculosis patients (RTB, and healthy control. The abundance-based coverage estimator (ACE showed the diversity index of the gut microbiota in the patients with recurrent tuberculosis was increased significantly compared with healthy controls (p < 0.05. At the phyla level, Actinobacteria and Proteobacteria, which contain many pathogenic species, were significantly enriched in the feces RTB patients. Conversely, phylum Bacteroidetes, containing a variety of beneficial commensal organisms, was reduced in the patients with the recurrent tuberculosis compared to healthy controls. The Gram-negative genus Prevotella of oral origin from phylum of Bacteroidetes and genus Lachnospira from phylum of Firmicutes were significantly decreased in both the new and recurrent TB patient groups, compared with the healthy control group (p < 0.05. We also found that there was a positive correlation between the gut microbiota and peripheral CD4+ T cell counts in the patients. This study, for the first time, showed associations between gut microbiota with tuberculosis and its clinical outcomes. Maintaining eubiosis, namely homeostasis of gut microbiota, may be beneficial for host recovery and prevention of recurrence of M. tuberculosis infection.

A retrospective study was made of 75 patients with tuberculosis and tuberculous pleurisy who received medical care in our hospital from 2002 through 2006. Of the 75 patients, 9 were admitted as tertiary emergency cases, and 12 patients were admitted by ambulance as secondary emergency cases. We studied the reason for their emergency medical admission, and the process of diagnosing 21 patients as tuberculosis. In some cases, the reasons for emergency admission were cardiorespiratory arrest, loss of consciousness, and injury resulting from a traffic accident, not common symptoms of tuberculosis such as dyspnea, hemoptysis and bloody sputum. Chest radiographic findings of most patients showed tuberculosis, and other cases were likely to be diagnosed as tuberculosis from their medical history or back-ground such as being homeless, previous tuberculosis, and receiving for therapy of tuberculosis. It was not so difficult to diagnose our cases as tuberculosis, nevertheless we may have an unconscious patient with normal chest radiograph. These data suggest that any patients visiting the emergency room may possibly have tuberculosis even if they are without respiratory symptoms.

Pulmonary tuberculosis caused by Mycobacterium tuberculosis remains a global problem. Inflammatory responses are the primary characteristics of patients with pulmonary tuberculosis in intensive care units (ICU). The aim of the present study was to investigate the clinical importance of inflammatory cells and factors for patients with pulmonary tuberculosis in ICU. A total of 124 patients with pulmonary tuberculosis in ICU were recruited for the present study. The inflammatory responses in patients with pulmonary tuberculosis in ICU were examined by changes in inflammatory cells and factors in the serum. The results indicated that serum levels of lymphocytes, plasma cells, granulocytes and monocytes were increased in patients with pulmonary tuberculosis in ICU compared with healthy controls. The serum levels of inflammatory factors interleukin (IL)-1, IL-6, IL-10, IL-12, and IL-4 were upregulated in patients with pulmonary tuberculosis in ICU. Lower plasma concentrations of IL-2, IL-15 and interferon-γ were detected in patients with pulmonary tuberculosis compared with healthy controls. It was demonstrated that high mobility group box-1 protein expression levels were higher in the serum of patients with pulmonary tuberculosis compared with healthy controls. Notably, an imbalance of T-helper cell (Th)1/Th2 cytokines was observed in patients with pulmonary tuberculosis. Pulmonary tuberculosis caused by M. tuberculosis also upregulated expression of matrix metalloproteinase (MMP)-1 and MMP-9 in hPMCs. In conclusion, these outcomes demonstrated that inflammatory responses and inflammatory factors are associated with the progression of pulmonary tuberculosis, suggesting that inhibition of inflammatory responses and inflammatory factors may be beneficial for the treatment of patients with pulmonary tuberculosis in ICU.

Tuberculosis (TB) is the 8th leading cause of death in the Philippines. A recent prevalence survey found that there were nearly 70% more cases of tuberculosis than previously estimated. Given these new data, the National TB Program (NTP), operating through a decentralized health system, identified about 58% of the estimated new drug-sensitive (DS) TB patients in 2016. However, the NTP only identified and commenced treatment for around 17% of estimated new drug-resistant patients. In order to reach the remaining 42% of drug-sensitive patients and 83% of drug-resistant patients, it is necessary to develop a better understanding of where patients seek care. National and regional patient pathway analyses (PPAs) were undertaken using existing national survey and NTP data. The PPA assessed the alignment between patient care seeking and the availability of TB diagnostic and treatment services. Systemic referral networks from the community-level Barangay Health Stations (BHSs) to diagnostic facilities have enabled more efficient detection of drug-sensitive tuberculosis in the public sector. Approximately 36% of patients initiated care in the private sector, where there is limited coverage of appropriate diagnostic technologies. Important differences in the alignment between care seeking patterns and diagnostic and treatment availability were found between regions. The PPA identified opportunities for strengthening access to care for all forms of tuberculosis and for accelerating the time to diagnosis by aligning services to where patients initiate care. Geographic variations in care seeking may guide prioritization of some regions for intensified engagement with the private sector. © The Author 2017.

Full Text Available Background: Compliance to therapy is one of the important factors that affect the outcome. Non-compliance to self administered multi drug tuberculosis treatment regimens is an important cause of failure of initial therapy and relapse as well as acquired drug resistance, requiring more prolonged and expensive therapy. Objective: To know the compliance of DOTS therapy in TB patients in District Raipur and to find out the reasons of non-compliance of DOTS therapy among the patients. Study Design: Cross sectional observational community based study. Study Setting: Microscopic Centers in District Raipur. Participants: 695 patients of Tuberculosis. Result: Study revealed that 65.93% patients had complied with the DOTS therapy and 33.38% were non compliant. Conclusion: Most of the reasons of non-Compliance can be averted by proper counseling of target group. Hence to achieve the goal of RNTCP, proper counseling of target group must be given top priority.

The founder of humanistic psychology A. Maslow divided the needs of a personality into several levels--from the lowest to the highest ones. Higher-leveled needs rise when the lower-leveled needs are satisfied. A great deal of factors affect the origination and satisfaction of needs, but they are always interrelated with social values. The extent to which personality needs are satisfied in patients with pulmonary tuberculosis has not been studied. A special questionnaire has been drawn up to study the extent to which personality needs are met. Its suitability has been determined, by using a group of patients with bronchial asthma. The extent to which personality needs are satisfied in patients with pulmonary tuberculosis was studied in 178 patients with infiltrative pulmonary tuberculosis and 253 patients with fibrocavernous pulmonary tuberculosis. The results have shown that the extent to which personality needs are satisfied in patients with tuberculosis is lower than that in apparently healthy individuals of the same social status. In females with infiltrative pulmonary tuberculosis, the needs for safety are satisfied to a lesser extent. In those with fibrocavernous pulmonary tuberculosis, the extent to which the physiological, safety, and self-realization needs is decreased. In males with infiltrative pulmonary tuberculosis, the physiological, noetic, and self-realization needs are satisfied to a lesser extent. In those with fibrocavernous pulmonary tuberculosis, the extent to which the physiological, safety, group decision-making, noetic and self-realization needs is decreased.

RATIONALE: In the absence of active tuberculosis, a positive tuberculin skin test (TST) or interferon-γ release assay (IGRA) result defines latent infection with Mycobacterium tuberculosis, although test results may vary depending on immunodeficiency. OBJECTIVES: This study compared the performance...... of TST and IGRAs in five different groups of immunocompromised patients, and evaluated their ability to identify those at risk for development of tuberculosis. METHODS: Immunocompromised patients with HIV infection, chronic renal failure, rheumatoid arthritis, solid-organ or stem-cell transplantation......, and healthy control subjects were evaluated head-to-head by the TST, QuantiFERON-TB-Gold in-tube test (ELISA), and T-SPOT.TB test (enzyme-linked immunospot) at 17 centers in 11 European countries. Development of tuberculosis was assessed during follow-up. MEASUREMENTS AND MAIN RESULTS: Frequencies of positive...

Smoking prolongs the infectivity of patients with tuberculosis.

LENUS (Irish Health Repository)

Siddiqui, U A

2010-10-01

We sought to establish if smokers on anti-tuberculosis treatment are more likely to have a prolonged period of infectivity, compared to non-smoking tuberculosis patients, in a low tuberculosis prevalence country. We conducted a cross-sectional, retrospective study in Ireland that recruited 53 microbiologically confirmed cases of pulmonary tuberculosis (PTB). The age-sex adjusted odds ratios (AOR) suggest that the infectivity status of PTB on treatment was four times more likely to be prolonged beyond 6-8 weeks, if the cases had a smoking history (AOR: 4.42; 95% CI: 1.23; 15.9). Smoking was associated with delayed sputum smear conversion in PTB patients on treatment.

Tuberculosis in patients with systemic lupus erythematosus: Spain's situation.

Science.gov (United States)

Arenas Miras, María del Mar; Hidalgo Tenorio, Carmen; Jimenez Alonso, Juan

2013-01-01

There has recently been an increase in the incidence of patients with systemic lupus erythematosus (SLE) due mainly to earlier diagnosis, and increased survival. Tuberculosis in our country is one of the most prevalent infectious diseases, and one of the underlying causes would be HIV infection and increased immigration from areas with high tuberculosis prevalence; this phenomenon is truly important in patients with autoimmune diseases, as clinical presentation, severity and prognosis of tuberculosis are often different to that of immunocompetent patients. Studies of tuberculosis in patients with SLE are scarce and inconclusive, with many doubts existing about the performance or non-tuberculous prophylaxis in this population and the absence of a protocol due to lack of conclusive studies. New techniques for diagnosis of tuberculosis (IGRAs) may be useful in this population due to higher sensitivity than Mantoux, helping avoid false negatives. Copyright © 2012 Elsevier España, S.L.

Background: Multidrug-resistant tuberculosis is a major worldwide health problem. In countries where tuberculosis is of moderate to high prevalence, the issue of Multidrug-resistant tuberculosis carries significant importance. Multidrug-resistant tuberculosis, similar to drug-sensitive tuberculosis, is contagious. Meanwhile its treatment is not only more difficult but also more expensive with lower success rates. Regarding clinical findings, there is no significant difference between Multidrug-resistant tuberculosis and drug-sensitive tuberculosis. Therefore determination of characteristic radiological findings in cases of Multidrug-resistant tuberculosis might be of help in early detection, and hence appropriate management of this disease condition. Objective: To explain the radiological spectrum of pulmonary Multidrug-resistant tuberculosis. Patients and methods: We retrospectively evaluated the radiographic images of 35 patients with clinically-and microbiologically- proven Multidrug-resistant tuberculosis admitted to our tertiary-care tuberculosis unit over a period of 13 months. The latest chest x-ray of all patients and the conventional chest CT scan without contrast of 15 patients were reviewed by three expert radiologists who rendered consensus opinion. Results: Of the 35 patients with imaging studies, 23 (66%) were male and 12 (34%) were female. The mean±SD age of participants was 38.2±17.3 (range: 16-20) years. 33 patients were known as secondary and only 2 had primary Multidrug-resistant tuberculosis. Chest radiography revealed cavitary lesion in 80% pulmonary infiltration in 89% and nodules in 80% of the cases. Pleurisy was the rarest finding observed in only 5 (14%) patients. All of 15 chest CT scans revealed cavitation, 93% of which were bilateral and multiple. Pleural involvement was seen in 93% of patients. Conclusion: Presence of multiple cavities, especially in both lungs, nodular and infiltrative lesions, and pleural effusion are main features

Seventy one patients with active pulmonary tuberculosis who died during the past 5 years (1989 to 1993) were evaluated on their causes of death. Twenty two patients (31%) died directly of tuberculosis, and among them, 18 patients (81%) of 22 patients who died of tuberculosis) had very advanced tuberculosis. The majority of them (64%) were old age over 70 years and were bedridden due mostly to cerebrovascular injuries. The serum level of albumin was low in all 17 patients in whom it was measured. Establishment of diagnosis of tuberculosis was delayed over one month after the onset of symptoms in 59% of patients who died of severe disease. Sixty one percent (11/18) of patients died within the first month after the initiation of chemotherapy and about 90% (16/18) died within 3 months. Two patients died from massive hemoptysis and other patients died of either respiratory failure or tuberculosis meningitis. From these observations it was found that very advanced tuberculosis was the major cause of death in patients who died of tuberculosis and that the advanced disease was chiefly caused by the delay on the establishment of diagnosis, and it was most important to detect tuberculosis as early as possible, with regular check up of chest X-ray and frequent examination for AFB (acid-fast bacilli) for tuberculosis suspected patients. On the other hand, the majority of patients (49/71) died of complicating medical problem unrelated to tuberculosis. Seventeen patients died from malignancy (seven lung cancer, four lymphoma, two laryngeal cancer, etc). Ten deaths were the result of bacterial superinfection. Other patients died from respiratory failure due to COPD, arteiosclerotic heart disease, or cerebrovascular injuries, etc. Two patients of old age died of hepatic failure possibly caused by adverse reaction of TB chemotherapy. It was found that diseases unrelated to tuberculosis were the cause of death in approximately 70% of patients with active tuberculosis, and it should

Full Text Available OBJECTIVE: To characterize time to sputum conversion among patients with multidrug resistant tuberculosis who were enrolled into second-line tuberculosis treatment program; to identify risk factors for delayed sputum conversion. DESIGN: Retrospective cohort study designed to identify the factors associated with sputum conversion. Survival analysis was performed using Kaplan-Meier estimator to compute estimates for median time to sputum conversion and Cox proportional hazards model to compute hazard ratios (HR. RESULTS: Sputum conversion from positive to negative was observed in 134 out of 195 cases (69%. Among these who converted the median time to conversion was 3.7 months. Factors independently associated with time to sputum conversion in the proportional hazards model were: male sex (HR=0.51, 95% CI 0.32-0.81, ofloxacin-resistant tuberculosis (HR = 0.45, 95% CI 0.26-0.78 and first period of recruitment into second-line treatment (HR= 0.69, 95% CI 0.47-1.01. CONCLUSION: Time to sputum conversion in patients with multidrug-resistant tuberculosis in Armenia was 5.8 months (range 0.5-17.0 months. High level of ofloxacin resistance was the main reason for compromised response to treatment. Patients with a poor resistance profile and males should be targeted with more aggressive initial therapy.

Objective: To study the imaging findings of disseminated pulmonary tuberculosis in patients with acquired immunodeficiency syndrome (AIDS). Methods: X-ray and multi-slice CT (MSCT) data from 33 AIDS patients with disseminated pulmonary tuberculosis confirmed by clinical manifestations and laboratory tests were analyzed retrospectively. Results: Thirty patients underwent initial chest radiography examination, 29 patients showed abnormal appearances, including bilateral disseminations in 21 patients and unilateral multiple disseminations in 8 patients. All patients underwent MSCT examination, 26 patients showed bilateral disseminations and 7 patients showed unilateral multiple disseminations. The abnormal pulmonary appearances included nodule (n = 25), miliary nodule (n = 22), air-space consolidation (n = 22), cavity (n = 11), fibrosis (n = 7), ground-glass opacity (n = 7), pneumatocele (n = 4), calcification (n = 2). There were 20 patients with more than 3 abnormal appearances and 13 patients with one or two abnormal appearances. The extra-pulmonary tuberculosis included pleural effusion (n = 33), lymphadenopathy (n = 30), intestinal tuberculosis (n = 3), splenic tuberculosis (n = 1) and cerebral tuberculosis (n = 1). Conclusion: Disseminated pulmonary tuberculosis should be highly suspected in AIDS patients with diffused nodules, miliary nodules, air-space consolidations or multiple cavities, accompanied with pleural effusion and lymphadenopathy.

To reduce the incidence of tuberculosis, it is insufficient to simply understand the dynamics of tuberculosis transmission. Rather, we must design and rigorously evaluate interventions to halt transmission, prioritizing those interventions most likely to achieve population-level impact. Synergy in reducing tuberculosis transmission may be attainable by combining interventions that shrink the reservoir of latent Mycobacterium tuberculosis infection (preventive therapy), shorten the time between disease onset and treatment initiation (case finding and diagnosis), and prevent transmission in key settings, such as the built environment (infection control). In evaluating efficacy and estimating population-level impact, cluster-randomized trials and mechanistic models play particularly prominent roles. Historical and contemporary evidence suggests that effective public health interventions can halt tuberculosis transmission, but an evidence-based approach based on knowledge of local epidemiology is necessary for success. We provide a roadmap for designing, evaluating, and modeling interventions to interrupt the process of transmission that fuels a diverse array of tuberculosis epidemics worldwide. © The Author 2017.

Full Text Available Patterns of disease, diagnosis, treatment and prognosis of tuberculosis in 100 patients co-infected with AIDS at Casa da AIDS clinic was studied. Demographic characteristics were as follows: 76 male patients, 24 female patients, 67 caucasian, average 35.8 years-old (SD ± 8.5. Sexual transmission of HIV was reported in 68 patients. Pulmonary tuberculosis was seen in 40 patients, extrapulmonary in 11, and combined in 49 patients. In 63 patients, TCD4+ counts were below 200/mm³ when tuberculosis was diagnosed. Fifty-five patients had their diagnoses confirmed by bacteriological identification of Mycobacterium; either through direct observation and/or culture. Tuberculosis was treated with rifampin, isoniazid and pyrazinamide in 60 patients, reinforced treatment in 14 and alternative treatment in the other 13 patients. Tuberculosis therapy lasted up to 9 months in 66% of the patients. Fifty-four patients were treated with a two-drug antiretroviral regimen and the remaining 46 patients received a triple regimen, which included a protease inhibitor. Among the latter, 35 patients were co-treated with rifampin. The occurrence of hepatic liver enzyme abnormalities was statistically related to alternative antiretroviral regimens (p = 0.01 and to the co-administration of rifampin and protease inhibitor (p = 0.019. Clinical resolution of tuberculosis was obtained in 74 patients. Twelve patients died during tuberculosis treatment. Resolution of tuberculosis was statistically significant related to antituberculosis treatment adherence (p = 0.001. The risk of no response to the treatment was 1.84 times more frequent among patients treated with alternative regimens regardless of the duration of the therapy. We conclude that the characteristics of tuberculosis in HIV infected patients requires that special attention be directed to the types and duration of both antiretroviral and anti-TB therapy in order to achieve the highest level of care.

Diminished Adherence and/or Ingestion of Virulent Mycobacterium tuberculosis by Monocyte-Derived Macrophages from Patients with Tuberculosis

The interaction between the macrophage and Mycobacterium tuberculosis is mediated by a variety of macrophage membrane-associated proteins. Complement receptors have been implicated in the adherence of M. tuberculosis to macrophages. In the present work, the adherence and/or ingestion of M. tuberculosis H37Rv to human monocyte-derived macrophages (MDM) from patients with tuberculosis (TB) and healthy controls was measured by microscopical examination, [3H]uracil incorporation, and CFU. The adherence and/or ingestion was enhanced by fresh serum and inhibited by heat inactivation, EDTA treatment, and anti-CR1 and anti-CR3 antibodies. Comparison of MDM from TB patients and healthy controls showed that the former exhibited a significantly decreased capacity to adhere and/or ingest M. tuberculosis, as determined by the number of CFU and 3H incorporation. The expression of CR1 (CD35) and CR3 (CD11b/CD18) on MDM from TB patients and healthy controls, as determined by flow cytometry, did not show significant differences. These results suggest that the lower ingestion of M. tuberculosis by MDM from TB patients is not due to defects in complement receptors, and therefore, there might be other molecules involved in the adherence and/or ingestion process that render MDM from TB patients ingest less mycobacteria than those from healthy controls.

Full Text Available OBJECTIVE: To determine the prevalence of nutritional deficiency among patients with pulmonary tuberculosis. METHODS: This was a cross-sectional study using data obtained from the Brazilian Case Registry Database and from the medical records of patients diagnosed with pulmonary tuberculosis (15-59 years of age residing in one of the municipalities that make up the 16th Regional Health District of the state of Bahia. We calculated the incidence, lethality, and mortality rates, as well as the prevalence of nutritional deficiency, as evaluated by body mass index. Demographic, social, clinical, and epidemiological data were collected. RESULTS: Of the 72 confirmed cases of tuberculosis, 59 (81.9% were in males, and 21 (29.2% of the patients were in the 40-49 year age bracket. The majority (85.3% described themselves as Mulatto or Black; 55.2% reported using alcohol; and approximately 90% were treated as outpatients. In the district and age bracket studied, the incidence of pulmonary tuberculosis was 30.6/100,000 population. Among the 72 patients, data regarding nutritional status was available for 34. Of those, 50% and 25%, respectively, presented nutritional deficiency at the beginning and at the end of treatment. No statistically significant differences were found between normal-weight and malnourished patients regarding the characteristics studied. CONCLUSIONS: The prevalence of nutritional deficiency was high among our sample of patients with pulmonary tuberculosis. This underscores the importance of nutritional follow-up for the assessment of tuberculosis treatment in the decision-making process regarding therapeutic interventions.

Full Text Available The goal of the study: to investigate treatment adherence in respiratory tuberculosis patients depending on the choice of therapy.Subjects and methods: retrospective full-design study. The case histories of adult new tuberculosis cases who were treated in TB Dispensary in 2015 were analyzed. The groups were formed based on the intake of combined drugs with fixed doses (1 tablet contained 60 mg of isoniazid, 120 mg of rifampicin, 300 mg of pyrazinamide, 225 mg of ethambutol, and 20 mg of pyridoxine – Group 1 (n = 38; or separate tablets in the doses as per drug use instructions (isoniazid, rifampicin, pyrazinamide, ethambutol – Group 2 (n = 78. The groups were compatible as per sex, age, and clinical manifestations of tuberculosis. Patients from Group 1 with the weight of 60 kg received 5 tablets and patients from Group 2 received more than 12 tablets. Patients' adherence to treatment was assessed as per regularity of intake and number of doses during the intensive phase of treatment.Results. Patients from Group 1 were regularly taking anti-tuberculosis drugs, while in Group 2 there were interruptions of treatment (7-21 days in 12 (15.4% patients. In Group, the intensive phase increased up to 90.2 ± 30.6 doses and in Group 2 this increase made 131.6 ± 65.4 doses due to late sputum conversion. In Group 1, sputum conversion was achieved during the first month of treatment in 60% of patients; and in Group 2 – in 10% of cases (p = 0.044. The frequency of transaminase elevation as a side effect was higher in Group 1, but it did not result in discontinuation of drugs. Thus, the intake of combined medication with fixed doses improved tuberculosis patients' adherence to treatment.

Endocrine dysfunction among adult patients with tuberculosis: An African experience

2014-01-01

Full Text Available A broad spectrum of endocrine conditions has been reported among adult patients with tuberculosis in Africa. This review aims to describe the magnitude and pathogenesis of the following endocrinopathies among patients with tuberculosis in Africa: adrenal insufficiency, diabetes mellitus, disorders of calcium and vitamin D metabolism, thyroid dysfunction and hypogonadism. PubMed database and Google scholar were used to search for the relevant published English language studies and case reports relating to endocrine abnormalities and tuberculosis in Africa up to July 2013. The search terms used were endocrine dysfunction, endocrine abnormalities, adrenal insufficiency, diabetes mellitus, thyroid dysfunction, hypogonadism, disorders of calcium and vitamin D metabolism, tuberculosis, Africa. Reference lists of the identified articles were further used to identify other studies. Adrenal insufficiency, diabetes mellitus and calcium-vitamin D abnormalities were the most prevalent and frequently reported endocrine disorders among adult patients with tuberculosis in Africa. A meticulous endocrine evaluation among tuberculosis patients with suspected endocrine abnormalities should be encouraged in Africa and other high TB endemic regions. Treatment of these endocrine disorders has generally been shown to improve quality of life and reduce mortality.

Natural History of Tuberculosis: Duration and Fatality of Untreated Pulmonary Tuberculosis in HIV Negative Patients: A Systematic Review

2011-01-01

Background The prognosis, specifically the case fatality and duration, of untreated tuberculosis is important as many patients are not correctly diagnosed and therefore receive inadequate or no treatment. Furthermore, duration and case fatality of tuberculosis are key parameters in interpreting epidemiological data. Methodology and Principal Findings To estimate the duration and case fatality of untreated pulmonary tuberculosis in HIV negative patients we reviewed studies from the pre-chemotherapy era. Untreated smear-positive tuberculosis among HIV negative individuals has a 10-year case fatality variously reported between 53% and 86%, with a weighted mean of 70%. Ten-year case fatality of culture-positive smear-negative tuberculosis was nowhere reported directly but can be indirectly estimated to be approximately 20%. The duration of tuberculosis from onset to cure or death is approximately 3 years and appears to be similar for smear-positive and smear-negative tuberculosis. Conclusions Current models of untreated tuberculosis that assume a total duration of 2 years until self-cure or death underestimate the duration of disease by about one year, but their case fatality estimates of 70% for smear-positive and 20% for culture-positive smear-negative tuberculosis appear to be satisfactory.

Candida species are emerging as a potentially pathogenic fungus in patients with broncho-pulmonary diseases. The synergistic growth promoting association of Candida and Mycobacterium tuberculosis has raised increased concern for studying the various Candida spp . and its significance in pulmonary tuberculosis patients during current years. This study was undertaken with the objective of discovering the prevalence of co-infection caused by different Candida species in patients with pulmonary tuberculosis. A total of 75 patients with pulmonary tuberculosis diagnosed by sputum Ziehl-Neelsen staining were included in the study. Candida co-infection was confirmed using the Kahanpaa et al. criteria. Candida species were identified using gram stain morphology, germ tube formation, morphology on cornmeal agar with Tween-80, sugar fermentation tests and HiCrome Candida Agar. Candida co-infection was observed in 30 (40%) of patients with pulmonary tuberculosis. Candida albicans was the most common isolate observed in 50% of the patients with co-infection, followed by C. tropicalis (20%) and C. glabrata (20%). Candida co-infection was found in 62.5% of female patients, while it was observed in only 29.4% of the male patients (P value 0.0133). Mean ± SD age of the patients with C. glabrata infection was 65.83 ± 3.19, while the mean ± SD age of the patients with other Candida infections was 43.25 ± 20.44 (P value 0.0138). Many patients with pulmonary tuberculosis have co-infection with Candida spp. The prevalence of non-albicans Candida species is increasing and may be associated with inadequate response to anti-tubercular drugs. C. glabrata infection has a strong association with old age.

In this cross-sectional study, mycobacteria specimens from 189 tuberculosis (TB) patients living in an urban area in Brazil were characterised from 2008-2010 using phenotypic and molecular speciation methods (pncA gene and oxyR pseudogene analysis). Of these samples, 174 isolates simultaneously grew on Löwenstein-Jensen (LJ) and Stonebrink (SB)-containing media and presented phenotypic and molecular profiles of Mycobacterium tuberculosis, whereas 12 had molecular profiles of M. tuberculosis based on the DNA analysis of formalin-fixed paraffin wax-embedded tissue samples (paraffin blocks). One patient produced two sputum isolates, the first of which simultaneously grew on LJ and SB media and presented phenotypic and molecular profiles of M. tuberculosis, and the second of which only grew on SB media and presented phenotypic profiles of Mycobacterium bovis. One patient provided a bronchial lavage isolate, which simultaneously grew on LJ and SB media and presented phenotypic and molecular profiles of M. tuberculosis, but had molecular profiles of M. bovis from paraffin block DNA analysis, and one sample had molecular profiles of M. tuberculosis and M. bovis identified from two distinct paraffin blocks. Moreover, we found a low prevalence (1.6%) of M. bovis among these isolates, which suggests that local health service procedures likely underestimate its real frequency and that it deserves more attention from public health officials.

Smoking promotes, among other health problems, the development of tuberculosis and the discovery of a case of tuberculosis can therefore be an opportunity for tobacco control interventions. We conducted a prospective study evaluating the knowledge of 37 Ivorian physicians (32 men and 5 women with 5 active smokers) on the relationship between smoking and tuberculosis and their attitudes to smoking tuberculous patients between February and August 2012 using an anonymous self-administered questionnaire. The response rate to the questionnaire was 88.1%. Among them, 70.3% of Ivorian physicians knew that smoking increased the incidence of tuberculosis, 75.7% said that forms of tuberculosis were more severe in smokers and about 27% thought that the cure rate of tuberculosis was lower in smokers. No significant difference was observed according to respondents' smoking status, or gender. Patients' smoking status was always assessed by 64.9% of physicians and by 78.4% in patients with tuberculosis, again not differing by physicians' smoking status or gender. The risks of smoking were always explained to patients with active pulmonary tuberculosis by 43.2% and benefits of stopping smoking ware always described in 35.1%. An intervention for smoking cessation was systematically offered to smokers having tuberculosis by 59.4% of physicians and 8.1% offered medication for smoking cessation. These results strongly support the need to reinforce physician behaviors to address smoking in patients with tuberculosis in Ivory Coast. Copyright © 2014 SPLF. Published by Elsevier Masson SAS.

Objective. To assess the utility of CT in the evaluation of pulmonary tuberculosis in patients without AIDS. Patients and methods. Thin-section CT scans for suspicion of pulmonary tuberculosis were obtained from 226 patients. A total of 38 patients were excluded; the reasons were unavailability of final results (n=18), patient unavailability for follow-up (n=13), and coexistence of tuberculosis and aspergilloma (n=7). The results from 188 patients were used for this study. After assessing the patterns of parenchymal lesion, involved segments, and presence of cavity, bronchiectases, and bronchogenic spread of the lesion with CT, tentative diagnosis and disease activity were recorded. Results. With CT, 133 of 146 patients (91%) with tuberculosis were correctly diagnosed as having pulmonary tuberculosis whereas 32 of 42 patients (76%) without tuberculosis were correctly excluded. CT diagnosis of lung cancer (n=8), bacterial pneumonia (n=2), pulmonary metastasis (n=1), chronic hypersensitivity pneumonia (n=1) and diffuse pan-bronchiolitis (n=1) turned out to be tuberculosis. Conversely CT diagnoses of tuberculosis appeared pathologically as lung cancer (n=5), bacterial pneumonia 71/89, 80%) and inactive state (51/57, 89%) of disease respectively could be correctly differentiated by CT. Conclusion. CT can be helpful in the diagnosis of pulmonary tuberculosis in most cases. On the basis of CT findings, distinction of active from inactive disease can be made in most cases. (authors)

Attitudes towards tuberculosis may have severe impact on individuals and their families as well as on the effectiveness of tuberculosis control programs. The purpose of this study was to describe these attitudes and explore the sources of tuberculosis information available to the general population in Croatia through a cross-sectional survey based on structured questionnaire using convenience sampling among 386 subjects aged 18 years and over. Data were stratified by sex, age groups, educational background, personal monthly income and contact with tuberculosis patient. Being near to a tuberculosis patient would be uncomfortable for 39.9% of respondents and 26.4% of subjects would avoid any contact. If they were sick of tuberculosis, 9.6% of respondents would keep it from the society. Less than 10% of study subjects would be ashamed of their own or potential tuberculosis in their family. Almost twice less subjects with high education would hide the disease (P=0.049), or be ashamed if sick in comparison with less educated respondents (P=0.036). The subjects who were not in contact were less likely to feel uncomfortable about being near to a tuberculosis patient (P=0.042). As the source of tuberculosis information, 61% of the subjects reported TV, radio and journals. Internet was the least used source (13.2%). The subjects in contact received information from the family or friends (P=0.025), while those without contact were informed through mass media (P<0.001). Study results revealed high stigma-generating attitudes towards tuberculosis. The strong potential of mass media capable of reaching different population groups should be used as part of the stigma-reduction strategies.

The 2011 edition of Specific Guiding Principles for Tuberculosis Prevention calls for a streamlined medical services system capable of providing medical care that is customized to the patient's needs. The new 21st Century Japanese version of the Directly Observed Treatment Short Course (DOTS) expands the indication of DOTS to all tuberculosis (TB) patients in need of treatment. Hospital DOTS consists of comprehensive, patient-centered support provided by a DOTS care team. For DOTS in the field, health care providers should select optimal administration support based on patient profiles and local circumstances. In accordance with medical fee revisions for 2012, basic inpatient fees have been raised and new standards for TB hospitals have been established, the result of efforts made by the Japanese Society for Tuberculosis and other associated groups. It is important that the medical care system be improved so that patients can actively engage themselves as a member of the team, for the ultimate goal of practicing patient-centered medicine. We have organized this symposium to explore the best ways for practicing patient-centered medicine in treating TB. It is our sincere hope that this symposium will lead to improved medical treatment for TB patients. 1. Providing patient-centered TB service via utilization of collaborative care pathway: Akiko MATSUOKA (Hiroshima Prefectural Tobu Public Health Center) We have been using two types of collaborative care pathway as one of the means of providing patient-centered TB services since 2008. The first is the clinical pathway, which is mainly used by TB specialist doctors to communicate with local practitioners on future treatment plan (e.g. medication and treatment duration) of patients. The clinical pathway was first piloted in Onomichi district and its use was later expanded to the whole of Hiroshima prefecture. The second is the regional care pathway, which is used to share treatment progress, test results and other

Full Text Available Background and objective: There are no recent data on the prevalence of drug-resistant tuberculosis (DR TB in Cambodia. We aim to describe TB drug resistance amongst adults with pulmonary and extra-pulmonary TB and human immunodeficiency virus (HIV co-infection in a national referral hospital in Phnom Penh, Cambodia. Design: Between 22 November 2007 and 30 November 2009, clinical specimens from HIV-infected patients suspected of having TB underwent routine microscopy, Mycobacterium tuberculosis culture, and drug susceptibility testing. Laboratory and clinical data were collected for patients with positive M. tuberculosis cultures. Results: M. tuberculosis was cultured from 236 HIV-infected patients. Resistance to any first-line TB drug occurred in 34.7% of patients; 8.1% had multidrug resistant tuberculosis (MDR TB. The proportion of MDR TB amongst new patients and previously treated patients was 3.7 and 28.9%, respectively (p<0.001. The diagnosis of MDR TB was made after death in 15.8% of patients; in total 26.3% of patients with MDR TB died. The diagnosis of TB was established by culture of extra-pulmonary specimens in 23.6% of cases. Conclusions: There is significant resistance to first-line TB drugs amongst new and previously treated TB–HIV co-infected patients in Phnom Penh. These data suggest that the prevalence of DR TB in Cambodia may be higher than previously recognised, particularly amongst HIV-infected patients. Additional prevalence studies are needed. This study also illustrates the feasibility and utility of analysis of non-respiratory specimens in the diagnosis of TB, even in low-resource settings, and suggests that extra-pulmonary specimens should be included in TB diagnostic algorithms.

Default remains an important challenge for the Revised National Tuberculosis Control Programme, which has achieved improved cure rates. This study describes the pattern of time of default in patients on DOTS. Tuberculosis Unit in District Tuberculosis Centre, Yavatmal, India; Retrospective cohort study. This analysis was done among the cohort of patients of registered at the Tuberculosis Unit during the year 2004. The time of default was assessed from the tuberculosis register. The sputum smear conversion and treatment outcome were also assessed. Kaplan-Meier plots and log rank tests. Overall, the default rate amongst the 716 patients registered at the Tuberculosis Unit was 10.33%. There was a significant difference in the default rate over time between the three DOTS categories (log rank statistic= 15.49, P=0.0004). Amongst the 331 smear-positive patients, the cumulative default rates at the end of intensive phase were 4% and 16%; while by end of treatment period, the default rates were 6% and 31% in category I and category II, respectively. A majority of the smear-positive patients in category II belonged to the group 'treatment after default' (56/95), and 30% of them defaulted during re-treatment. The sputum smear conversion rate at the end of intensive phase was 84%. Amongst 36 patients without smear conversion at the end of intensive phase, 55% had treatment failure. Patients defaulting in intensive phase of treatment and without smear conversion at the end of intensive phase should be retrieved on a priority basis. Default constitutes not only a major reason for patients needing re-treatment but also a risk for repeated default.

Full Text Available Aims: To describe the number, types and reasons of consultations amongst patients of pulmonary tuberculosis from an urban area. Settings and Design Cross sectional study was conducted amongst new patients of pulmonary tuberculosis initiated on DOTS at District Tuberculosis Centre (DTC, Yavatmal from January to June 2006. Material and Methods: The data regarding consultations were collected along a time line. The reasons for consultations were studied by in-depth interviews. Statistical analysis: Logistic regression analysis and transcripts of interviews. Results and Conclusions A total of 55 patients were studied in whom median duration between first consultation to treatment initiation was 15 days. A majority of cases (87.27% had first consulted a private practitioner. A total of 32 patients reported more than two consultations and 19 had consulted more than two private health service providers. Amongst the movements between consultations, a majority were from private to government. Only four patients had come to DTC without any prior consultation. Many patients came to government health service provider on their own when the symptomatic treatment prescribed by the private practitioners did not relieve their symptoms.

Tuberculosis involving the central nervous system (CNS) is rarely observed in non immuno-compromised hosts. We report herin the various clinical, biological and radiological manifestations observed in 7 patients with CNS tuberculosis. Clinical and biological records of 7 patients with CNS tuberculosis were retrospectively studied. All patients had encephalic CT-scan and MRI in the course of the disease. 5 women and 2 men with a mean age of 38.4 years initially initially presented with headache (n = 6), fever (n = 5), meningeal irritation (n = 3), localizing neurological signs (n = 1). Lumbar punction revealed lymphocytic meningitis (n = 6/7). Mycobacterium tuberculosis or bovis was isolated in 3 patients only. Cerebral tomodensitography or magnetic resonance imaging were initially normal in most of cases (n = 4/7), but discovered in the course of disease basilar meningitis (n = 6), hydrocephalus (n = 6), abcess or tuberculoma (n = 4). In all the patients, initiation of the treatment was complicated by clinical and/or biological deterioration, called paradoxal reaction, leading in all cases to glucocorticoid adjunction, with various final results. Indeed, 4 patients developed neurological sequelae. No patient died. CNS tuberculosis is a rare disease in non immunocompromised patients whose diagnostic may be difficult due to the absence of specific clinical symptoms, negative initial radiological examination, as well as delayed and often negative bacterial isolation. Paradoxal reaction appeared to be frequent despite specific antibiotherapy and underlines the beneficial effects of addictive corticosteroids.

Development of rapid diagnostic tests for tuberculosis is a global priority. A whole proteome screen identified Mycobacterium tuberculosis antigens associated with serological responses in tuberculosis patients. We used World Health Organization (WHO) target product profile (TPP) criteria for a detection test and triage test to evaluate these antigens. Consecutive patients presenting to microscopy centers and district hospitals in Peru and to outpatient clinics at a tuberculosis reference center in Vietnam were recruited. We tested blood samples from 755 HIV-uninfected adults with presumptive pulmonary tuberculosis to measure IgG antibody responses to 57 M. tuberculosis antigens using a field-based multiplexed serological assay and a 132-antigen bead-based reference assay. We evaluated single antigen performance and models of all possible 3-antigen combinations and multiantigen combinations. Three-antigen and multiantigen models performed similarly and were superior to single antigens. With specificity set at 90% for a detection test, the best sensitivity of a 3-antigen model was 35% (95% confidence interval [CI], 31-40). With sensitivity set at 85% for a triage test, the specificity of the best 3-antigen model was 34% (95% CI, 29-40). The reference assay also did not meet study targets. Antigen performance differed significantly between the study sites for 7/22 of the best-performing antigens. Although M. tuberculosis antigens were recognized by the IgG response during tuberculosis, no single antigen or multiantigen set performance approached WHO TPP criteria for clinical utility among HIV-uninfected adults with presumed tuberculosis in high-volume, urban settings in tuberculosis-endemic countries. © The Author 2017.

2011-12-01

Full Text Available Abstract Background India has 2.0 million estimated tuberculosis (TB cases per annum with an estimated 280,000 TB-related deaths per year. Understanding when in the course of TB treatment patients die is important for determining the type of intervention to be offered and crucially when this intervention should be given. The objectives of the current study were to determine in a large cohort of TB patients in India:- i treatment outcomes including the number who died while on treatment, ii the month of death and iii characteristics associated with "early" death, occurring in the initial 8 weeks of treatment. Methods This was a retrospective study in 16 selected Designated Microscopy Centres (DMCs in Hyderabad, Krishna and Adilabad districts of Andhra Pradesh, South India. A review was performed of treatment cards and medical records of all TB patients (adults and children registered and placed on standardized anti-tuberculosis treatment from January 2005 to September 2009. Results There were 8,240 TB patients (5183 males of whom 492 (6% were known to have died during treatment. Case-fatality was higher in those previously treated (12% and lower in those with extra-pulmonary TB (2%. There was an even distribution of deaths during anti-tuberculosis treatment, with 28% of all patients dying in the first 8 weeks of treatment. Increasing age and new as compared to recurrent TB disease were significantly associated with "early death". Conclusion In this large cohort of TB patients, deaths occurred with an even frequency throughout anti-TB treatment. Reasons may relate to i the treatment of the disease itself, raising concerns about drug adherence, quality of anti-tuberculosis drugs or the presence of undetected drug resistance and ii co-morbidities, such as HIV/AIDS and diabetes mellitus, which are known to influence mortality. More research in this area from prospective and retrospective studies is needed.

To evaluate high-resolution CT(HRCT) findings of the miliary tuberculosis and their significance. We retrospectively studied clinical records, HRCT and chest radiographs of 14 patients with miliary tuberculosis. On HRCT, nodules were seen in all 14 cases, 10 of them evenly, and 4 were irregularly distributed. The size of each nodule was less than 1 mm in 7 cases, 1 - 2 mm in 6 cases, and 3 mm or more in 1 case. The ground - glass opacity was accompanied in 8 cases, and fine reticular opacity was also noted in 8 cases. Other associated findings were pleural effusion (n=4), hilar and mediastinal lymphadenopathy (n=3), consolidation of the exudative tuberculosis (n=4). HRCT findings of miliary tuberculosis are diffusely distributed micro nodules of variable size, less than 5 mm in diameter. The ground-glass opacity can be combined

Objective/background: Tuberculosis (TB) is a worldwide public health problem. It is a contagious and grave disease caused by Mycobacterium tuberculosis. Current drugs such as isoniazid, pyrazinamide, and rifampicin used for the treatment of tuberculosis are potentially hepatotoxic and can lead to drug hepatitis. In order to improve the follow-up of TB patients in Cameroon, we carried out a study which aimed to evaluate the hepatotoxicity risk factors associated with anti-TB drugs. Methods:...

Observational data from Eastern Europe on the management and outcome of multi-drug-resistant tuberculosis (MDR TB) in HIV positive populations remain sparse in the English-language literature. We compared clinical characteristics and outcomes of 55 patients who were diagnosed with HIV and MDR TB in Eastern Europe between 2004 and 2006 to 89 patients whose Mycobacterium tuberculosis isolates were susceptible to isoniazid and rifampicin. Patients with HIV and MDR TB were young and predominantly male with high rates of intravenous drug use, imprisonment and hepatitis C co-infection. Eighty-four per cent of patients with MDR TB had no history of previous TB drug exposure suggesting that the majority of MDR TB resulted from transmission of drug-resistant M. tuberculosis. The use of non-standardized tuberculosis treatment was common, and the use of antiretroviral therapy infrequent. Compared to those with susceptible tuberculosis, patients with MDR TB were less likely to achieve cure or complete tuberculosis treatment (21.8% vs. 62.9%, p < 0.0001), and they were more likely to die (65.5% vs. 27.0%, p < 0.0001). Our study documents suboptimal management and poor outcomes in HIV positive patients with MDR TB. Implementation of WHO guidelines, rapid TB diagnostics and TB drug susceptibility testing for all patients remain a priority in this region. Copyright © 2013 The British Infection Association.

Whether the main points of treatment for bronchial obstructive syndrome (BOS) in chronic obstructive lung disease (COLD) can be adapted for patients with pulmonary tuberculosis (PT) was studied. For this purpose, 435 patients with PT with signs of BOS (forced expiratory volume at 1 second (FEV1) 70% of the normal values; 2) 229 patients with FEV1 69-50%; 3) 102 patients with FEV1 bronchial obstructive syndrome in patients with pulmonary tuberculosis was highly effective, promotes the amelioration of the degree of respiratory symptoms in patients with IPT by 2 to 8 times, in those with FCPT by more than 2-3 times, and in those with PS by 1.45-10 times. The differences in the efficiency of bronchodilator therapy depend on the baseline level of bronchial obstruction. In patients with pulmonary tuberculosis concurrent with BO, the use of current inhalation bronchodilator therapy results in a substantial increase in FEV1, which differentiates BOS in PT from COLD. The use of the proposed therapy in the multimodality treatment of patients with pulmonary tuberculosis showed no statistically significant differences in the changes in the degree of X-ray symptoms while this therapy permits acceleration of abacillation in patients with IPT by 16.8% and in those with FCPT by 14.8%. Effective bronchodilator therapy considerably enhances life quality in patients. Thus, early systematic and long-term performance of the bronchodilator therapy, based on the principles of bronchodilator therapy for COLD, in patients with PT concurrent with BOS may substantially enhance the efficiency of treatment in this category of patients.

2017-01-01

Full Text Available The article analyzes the differences in clinical and laboratory manifestations of tuberculosis and mycobacteriosis in HIV patients. It was found out that mycobacteriosis developed mostly in the socially well patients at the advanced stages of HIV infection. In case of mycobacteriosis, lesions were mostly located in the abdomen with limited inflammation in the chest, while in case of tuberculosis pulmonary lesions dominated. A negative result of sputum PCR assays for tuberculosis mycobacteria with a positive result of the test for AFB is an important sign for differential diagnostics. The obtained results allow performing differential diagnostics of these diseases in those HIV infected.

To evaluate the CT spectrum of pulmonary tuberculosis, we reviewed CT of the chest in 80 adult patients with active pulmonary tuberculosis who had not been treated for tuberculosis. Main patterns seen in patients with active tuberculosis were: (1) nodular shadow (56%), (2) confluent consolidation (15%), and (3) round consolidation (16%). Other CT patterns were: (1) miliary tuberculosis (n=4), (2) pleural effusion only (n=4), and (3) normal chest (n=2). Major features seen at CT included segmental distribution (97%), satellite lesions (86%), single cavity in each cavitary lesion (95%), ectatic change of the bronchi, tendency of distortion or contraction.

The frequency of the Beijing genotype of Mycobacterium tuberculosis as a cause of tuberculosis (TB) in South America was determined by analyzing genotypes of strains isolated from patients that had been diagnosed with the disease between 1997 and 2003 in seven countries of the subcontinent. In total, 19 of the 1,202 (1.6%) TB cases carried Beijing isolates, including 11 of the 185 patients from Peru (5.9%), five of the 512 patients from Argentina (1.0%), two of the 252 Brazilian cases (0.8%), one of the 166 patients from Paraguay (0.6%) and none of the samples obtained from Chile (35), Colombia (36) and Ecuador (16). Except for two patients that were East Asian immigrants, all cases with Beijing strains were native South Americans. No association was found between carrying a strain with the Beijing genotype and having drug or multi-drug resistant disease. Our data show that presently transmission of M. tuberculosis strains of the Beijing genotype is not frequent in Latin America. In addition, the lack of association of drug resistant TB and infection with M. tuberculosis of the Beijing genotype observed presently demands efforts to define better the contribution of the virulence and lack of response to treatment to the growing spread of Beijing strains observed in other parts of the world.

For a cohort of patients with tuberculosis in Carabayllo, Peru, we describe the prevalence of medical comorbidities and socio-economic needs, the efforts required by a comprehensive support programme ('TB Cero') to address them and the success of this programme in linking patients to care. Patients diagnosed with tuberculosis in Carabayllo underwent evaluations for HIV, diabetes, mental health and unmet basic needs. For patients initiating treatment during 14 September, 2015-15 May, 2016, we abstracted data from evaluation forms and a support request system. We calculated the prevalence of medical comorbidities and the need for socio-economic support at the time of tuberculosis diagnosis, as well as the proportion of patients successfully linked to care or support. Of 192 patients, 83 (43%) had at least one medical comorbidity other than tuberculosis. These included eight (4%) patients with HIV, 12 (6%) with diabetes and 62 (32%) deemed at risk for a mental health condition. Of patients who required follow-up for a comorbidity, 100% initiated antiretroviral therapy, 71% attended endocrinology consultations and 66% attended psychology consultations. Of 126 (65%) patients who completed the socio-economic evaluation, 58 (46%) reported already receiving food baskets from the municipality, and 79 (63%) were given additional support, most commonly food vouchers and assistance in accessing health care. Carabayllo tuberculosis patients face many challenges in addition to tuberculosis. A collaborative, comprehensive treatment support programme can achieve high rates of linkage to care for these needs. © 2017 John Wiley & Sons Ltd.

According to the degree of immunosuppression and the Centers for Disease Control (CDC) and Prevention classification (Atlanta, USA, 1993), the patients were divided into 3 groups: (1) CD4 > or = 500 cells/microl (n = 10); 2) CD4 200-499 cells/microl (n = 28); (3) CD4 <200 cells/microl (n = 36). With spiral CT, focal changes with a predominance of clear-cut foci are visualized at a high frequency in the patients with pulmonary tuberculosis in the presence of HIV infection. In progressive immunosuppression, the CT pattern displays atypical syndromes (frosted glass-type foci, interstitial infiltration, and thin-walled cavities) with the lower rate of alveolar infiltration with confluent foci, as well as lung tissue decay. Enlarged intrathoracic lymph nodes are characteristic of 70.0% of the patients with HIV infection and tuberculosis regardless of the level of CD4 cells. As immunosuppression progresses, the CT pattern of respiratory tuberculosis in the presence of HIV infection shows as atypical syndromes (unclearly defined frosted glass-type focal changes, interstitial infiltrations, and thin-walled cavernous masses). A marked polymorphism in changes and a high rate of lymph node involvement are characteristic.

Observational data from Eastern Europe on the management and outcome of multi-drug-resistant tuberculosis (MDR TB) in HIV positive populations remain sparse in the English-language literature.We compared clinical characteristics and outcomes of 55 patients who were diagnosed with HIV and MDR TB...... in Eastern Europe between 2004 and 2006 to 89 patients whose Mycobacterium tuberculosis isolates were susceptible to isoniazid and rifampicin.Patients with HIV and MDR TB were young and predominantly male with high rates of intravenous drug use, imprisonment and hepatitis C co-infection. Eighty-four per cent...... of patients with MDR TB had no history of previous TB drug exposure suggesting that the majority of MDR TB resulted from transmission of drug-resistant M. tuberculosis. The use of non-standardized tuberculosis treatment was common, and the use of antiretroviral therapy infrequent. Compared to those...

Pakistan has the sixth largest population in the world and boasts the fifth greatest burden of tuberculosis. The Government of Pakistan has set the ambitious goal of zero deaths due to tuberculosis and universal access to tuberculosis care by 2020. Successfully reaching these goals is dependent on the country's capacity to diagnose and successfully treat an estimated 200000 unnotified or missing patients with tuberculosis. A patient-pathway analysis (PPA) was conducted at the national level, as well as for each of the 4 provinces, to assess the alignment between patient care seeking and the availability of tuberculosis diagnostic and treatment services. Almost 90% of patients initiated care in the private sector, which accounts for only 15% of facilities with the capacity for tuberculosis diagnosis and treatment. Across the country, nearly 50% of tuberculosis microscopy laboratories were located in public-sector-basic health units and regional health centers. However, very few patients initiated care in these facilities. Overall, tuberculosis case detection was high given the low likelihood of patients reaching facilities with the capacity for tuberculosis service delivery during their first visit. Improving the engagement of the informal sector and lower-level clinicians will improve the efficiency and timeliness of tuberculosis diagnosis for patients in Pakistan. Concurrently, the apparent strength of the referral networks connecting community-level workers and private clinicians to the public sector for tuberculosis diagnosis and treatment suggests that strengthening the capacity of the public sector could be valuable. © The Author 2017.

Background. Isolation of patients suspected for pulmonary tuberculosis is guided by serial sputum smears. This can result in isolation for days for patients with noncontagious tuberculosis. To determine whether a single sample negative for Mycobacterium tuberculosis complex at polymerase chain...... reaction (PCR) can guide isolation. Methods. We retrospectively evaluated sputum samples analyzed for M. tuberculosis complex at the International Reference Laboratory of Mycobacteriology, Copenhagen, Denmark in 2002–2011. We selected culture-confirmed tuberculosis cases with ≥3 samples within 14 days...... before or after the initial culture-positive sample. We repeated the process for those with ≥2 samples within 28 days. The primary outcome was PCR-negative, smear-positive patients. Results. We included 53 533 sputum samples from 20 928 individuals; 1636 had culture-confirmed tuberculosis. Of these, 856...

In Ethiopia, extensive scale-up of the availability of health extension workers (HEWs) at the community level has been credited with increased identification and referral of patients with presumptive tuberculosis, which has contributed to increased tuberculosis case notification and better treatment outcomes. However, nearly 30% of Ethiopia's estimated 191000 patients with tuberculosis remained unnotified in 2015. A better understanding of patient care-seeking practices may inform future government action to reach all patients with tuberculosis. A patient-pathway analysis was completed to assess the alignment between patient care initiation and the availability of diagnostic and treatment services at the national level. More than one third of patients initiated care with HEWs, who refer patients to health centers for diagnosis. An additional one third of patients initiated care at health centers. Of those health centers, >80% had microscopy services, but few had access to Xpert. Despite an extensive microscopy and radiography network at middle levels of the health system, a quarter of all notified patients with tuberculosis had no bacteriological confirmation of disease. While 30% of patients reported receiving some form of care from the private sector, private-sector facilities, especially pharmacies, were not widely accessed for tuberculosis diagnosis. The availability of HEWs can increase access to tuberculosis diagnostic and treatment support services, particularly for rural populations. Continued strengthening of referral systems from HEWs and health posts are needed to enable consistent and timely access to Xpert as an initial diagnostic test and to drug resistance screening. © The Author 2017.

There is no biomarker for diagnosing active tuberculosis in patients with human immunodeficiency virus (HIV) infection. Indoleamine 2, 3-dioxygenase (IDO) is an immunoregulatory enzyme that breaks down tryptophan (Trp) to metabolites known as kynurenines (Kyns). We investigated whether IDO activity, as measured by the ratio of Kyn to Trp, could be used to diagnose or predict active tuberculosis disease in HIV-infected adults. Kyn and Trp concentrations were measured using ultraperformance liquid chromatography mass spectrometry in plasma samples from 32 HIV-infected patients in whom active tuberculosis developed and who were followed up prospectively. We compared to 70 HIV-infected control subjects from the same cohort in whom tuberculosis did not develop, matched by age, sex, and CD4 cell count, and 37 unmatched HIV-infected patients with a diagnosis of pneumonia. Clinical parameters, including body mass index, CD4 cell count, HIV load, and C-reactive protein levels were analyzed. At the time of tuberculosis diagnosis, IDO activity was significantly higher in patients with tuberculosis than in controls (P tuberculosis diagnosis, IDO activity was significantly higher in all patients who later developed tuberculosis (P tuberculosis treatment, IDO activity in patients with tuberculosis declined to levels similar to those in controls. IDO activity was 4-fold higher in patients with tuberculosis than in those with pneumonia, and could be used to distinguish them. With a receiver operating characteristic curve, IDO activity had a sensitivity of 97%, a specificity of 99%, and positive and negative predictive values of 89% and 100% for detecting active tuberculosis disease. Plasma IDO activity is suitable as a biomarker of active tuberculosis in HIV-positive patients. © The Author 2017.

The convergence of tuberculosis and diabetes represents a co-epidemic that threatens progress against tuberculosis. We have investigated type 2 diabetes as a risk factor for tuberculosis susceptibility, and have used as experimental model whole blood infected in vitro with Mycobacterium tuberculosis. Blood samples from diabetic patients were found to have a higher absolute neutrophil count that non-diabetic controls, but their immune functionality seemed impaired because they displayed a lower capacity to phagocytose M. tuberculosis, a finding that had been previously reported only for monocytes. In contrast, an increased production of TNFα was detected in infected blood from diabetic patients. Despite the altered phagocytic capacity showed by cells from these patients, the antimicrobial activity measured in both whole blood and monocyte derived macrophages was similar to that of controls. This unexpected result prompts further improvements in the whole blood model to analyze the immune response of diabetes patients to tuberculosis.

In Hungary the incidence of tuberculosis among the homeless population was 676 per 100,000 in 2002. Sixty-nine percent (140 patients) of all homeless tuberculosis patients were notified in Budapest (the capital). Therefore, a retrospective study that included 66 homeless tuberculosis patients notified in Budapest in 2002 was conducted to determine the rate of recent transmission of the disease and medical risk factors and to identify transmission pathways by means of conventional and molecular epidemiologic methods. IS6110 DNA fingerprinting revealed that 71.2% of the isolates could be clustered. Thirty-four (51.5%) patients belonged to five major clusters (size, from 4 to 11 individuals), and 13 (19.7%) belonged to six smaller clusters. Additional analysis of patient records found that 2 (18%) of the 11 patients in cluster A, 3 (37.5%) of the 8 patients in cluster B, and 2 (33%) of the 6 patients in cluster C were residents of the same three homeless shelters during the diagnosis of tuberculosis. Review of the database of the National Tuberculosis Surveillance Center (NTSC) revealed that 21.2% of the cases have not been reported to the NTSC. These findings indicate that the screening and treatment of tuberculosis among the homeless need to be strengthened and also warrant the review of environmental control steps in public shelters. Improvement of adherence of clinicians to surveillance reporting regulations is also necessary. PMID:15583345

Full Text Available Persons infected with the Human Immunodeficiency Virus (HIV are particularly susceptible to tuberculosis, either by latent infection reactivation or by a primary infection with rapid progression to active disease. This study was done to determine the frequency of tuberculosis infection among Iranian patients with HIV/AIDS. A total of 262 HIV/AIDS patients attending all three HIV/AIDS health care centers of Tehran, Iran were enrolled in this study. A detailed history and physical examination were obtained from all HIV patients suspected of having pulmonary M. tuberculosis. A positive PPD skin test was used as a diagnostic parameter for probability of TB infection. Out of 262 HIV/AIDS patients, a total of 63 (24% were shown to have the tuberculosis infection based on a positive PPD skin test. Of the patients with positive PPD skin test, 22 (35% had pulmonary Tuberculosis, 2 (3.2% had extrapulmonary tuberculosis, and 39 (53% had no evidence of M. tuberculosis infection (latent infection. Also 8 (12.7% had history of long term residence in a foreign country, 32 (50.8% were exposed to an index case, and 9 (14.3% had past history of pulmonary tuberculosis, while only 33.3% had clinical manifestations of TB (active disease. There was no resistant case of tuberculosis. Our study showed that near 24% of Iranian patients with HIV/AIDS were infected with M. tuberculosis. This finding denotes the need to improve the diagnostic and preventive measures, and also prompt treatment of this type of infection in the HIV infected individuals.

Among adults with signs and symptoms of pulmonary tuberculosis (TB), recognition of transmissible TB has implications for airborne infection isolation and public health activities. Sputum smear-negative TB patients account for around one-fifth of tuberculosis transmission. The tuberculosis transmission risk of TB patients with negative results on nucleic acid amplification (NAA) testing of respiratory specimens has not been established. We sought to estimate the tuberculosis transmission risk of NAA test-negative TB patients. We retrospectively reviewed Maryland TB program data from 2004 to 2009 during which NAA testing by the Mycobacterium Tuberculosis Direct Test (MTD) was performed routinely. Patients with sputum Mycobacterium tuberculosis (M.tb) isolates having matching genotypes were assigned to clusters. Transmission sequence was approximated by collection order of individuals' first culture-positive specimens. Minimum transmission risks of NAA (MTD)-negative TB patients and of smear-negative TB patients were estimated based on individuals' positions within clusters. Among 809 patients with culture-confirmed TB, M.tb genotypes were available for 782 (96.7%). For NAA-negative TB patients the minimum transmission risk estimate was 5.1% (95% CI 0-11.4). For smear-negative TB patients the minimum transmission risk estimate was 11.2% (95% CI 7.2-15.3). Minimum transmission risk of NAA-negative TB patients was lower than that of smear-negative TB patients. However, transmission risk of NAA-negative TB patients appears to not be negligible.

Emerging evidence shows that microRNAs (miRNAs) play an important role in pathogen-host interactions. Circulating miRNAs have been repeatedly and stably detected in blood and hold promise to serve as molecular markers for diverse physiological and pathological conditions. To date, the relationship between circulating miRNAs and active pulmonary tuberculosis (TB) has not been reported. Using microarray-based expression profiling followed by real-time quantitative PCR validation, the levels of circulating miRNAs were compared between patients with active pulmonary tuberculosis and matched healthy controls. The receiver operating characteristic curve was used to evaluate the diagnostic effect of selected miRNA. Bioinformatic analysis was used to explore the potential roles of these circulating miRNAs in active pulmonary tuberculosis infection. Among 92 miRNAs significantly detected, 59 miRNAs were downregulated and 33 miRNAs were upregulated in the TB serum compared to their levels in the control serum. Interestingly, only two differentially expressed miRNAs were increased not only in the serum but also in the sputum of patients with active pulmonary tuberculosis compared to the levels for the healthy controls. Upregulated miR-29a could discriminate TB patients from healthy controls with reasonable sensitivity and specificity. A number of significantly enriched pathways regulated by these circulating miRNAs were predicted, and most of them were involved in acute-phase response, inflammatory response, and the regulation of the cytoskeleton. In all, for the first time our results revealed that a number of miRNAs were differentially expressed during active pulmonary tuberculosis infection, and circulating miR-29a has great potential to serve as a marker for the detection of active pulmonary tuberculosis infection.

Little information exists on the frequency, severity, and timing of first-line anti-tuberculosis drug-related adverse events (TB-AEs) in HIV-tuberculosis coinfected (HIV-TB) patients in the antiretroviral therapy (ART) era. This matched-cohort study included HIV-TB patients as cases and HIV-uninfected tuberculosis (non-HIV-TB) patients as controls. Tuberculosis was culture-confirmed in both groups. Cases were matched to controls in a 1:4 ratio on age, sex, and year of diagnosis. TB-AEs were defined as Grade 2 or higher requiring drug discontinuation/regimen change. From 2003 to 2015, 94 cases and 376 controls were analyzed (95% men, 98% Asians). Standard four-drug combination therapy was initiated in 91% of cases and 89% of controls (p = 0.45). Cases had a higher frequency of TB-AE [51% (48/94) vs. 10% (39/376), p tuberculosis treatment. HIV infection was an independent risk factor for TB-AEs in the multivariate Cox analysis [adjusted HR (aHR): 6.96; 95% confidence interval: 3.93-12.3]. TB-AEs occurred more frequently in HIV-TB than in non-HIV-TB patients, and were more severe. The majority of TB-AEs occurred within 4 weeks of initiating anti-tuberculosis treatment. Because TB-AEs may delay ART initiation, careful monitoring during this period is warranted in coinfected patients.

Tuberculosis (TB) is a major public health problem in the world and Africa has approximately one quarter of the world's cases. One of the greatest challenges facing most TB programmes is the non-compliance to TB treatment among TB patients. This study aimed at determining the challenges of management of tuberculosis (TB) across selected Osun State health facilities. The study employed a descriptive cross-sectional design. A semi-structured questionnaire was used to collect data from 102 TB patients in the health facilities. The instrument measured socio-demographic variables, patient related factors, socio-economic variables, health care system related factors to TB disease and treatment. Data were analysed and summarized using descriptive and inferential statistics. Statistical significance was placed at p facilities (χ2 = 21.761, p facility and patient-related factors were largely responsible.

Full Text Available Objective: To assess Mycobacterium tuberculosis (M. tuberculosis strains exsisting in Gedeo zone and the surrounding areas of the Southern Ethiopia using spoligotyping. Methods: A cross sectional study was carried out from February, 2012 to June, 2013 and 97 (76 sputum and 21 fine needle aspirate samples were taken from tuberculosis diagnosed patients at Dilla University Referral Hospital and other private clinics. Culturing, region of difference (RD9 deletion typing and spoligotyping techniques were employed to isolate M. tuberculosis strains. Results: Growth of mycobacteria was observed in 35.1% (34/97. Speciation of isolates showed that 91.2% (31/34 of the isolates were M. tuberculosis. Further characterization led to the identification of 23 different spoligotype patterns of M. tuberculosis of which 61% and 39% displayed unique and cluster patterns, respectively. The most dominant shared type was spoligotype international type 53. Of the 23 strains, 12 have not been registered in the international spoligotyping database (SpolDB4. Seventy one percent of the strains belonged to the Euro-American lineage. Conclusions: This study revealed the existence of both genetically diverse and clustered M. tuberculosis strains from tuberculosis patients in the area, suggesting reactivation of infection and recent transmission, respectively. Molecular epidemiology of M. tuberculosis should be done nationwide in order to set appropriate control measures.

Tuberculosis and nutrition

2009-01-01

Full Text Available Malnutrition and tuberculosis are both problems of considerable magnitude in most of the underdeveloped regions of the world. These two problems tend to interact with each other. Tuberculosis mortality rates in different economic groups in a community tend to vary inversely with their economic levels. Similarly, nutritional status is significantly lower in patients with active tuberculosis compared with healthy controls. Malnutrition can lead to secondary immunodeficiency that increases the host′s susceptibility to infection. In patients with tuberculosis, it leads to reduction in appetite, nutrient malabsorption, micronutrient malabsorption, and altered metabolism leading to wasting. Both, protein-energy malnutrition and micronutrients deficiencies increase the risk of tuberculosis. It has been found that malnourished tuberculosis patients have delayed recovery and higher mortality rates than well-nourished patients. Nutritional status of patients improves during tuberculosis chemotherapy. High prevalence of human immunodeficiency (HIV infection in the underdeveloped countries further aggravates the problem of malnutrition and tuberculosis. Effect of malnutrition on childhood tuberculosis and tuberculin skin test are other important considerations. Nutritional supplementation may represent a novel approach for fast recovery in tuberculosis patients. In addition, raising nutritional status of population may prove to be an effective measure to control tuberculosis in underdeveloped areas of world.

In household contact investigations of tuberculosis (TB), a second tuberculin skin test (TST) obtained several weeks after a first negative result consistently identifies individuals that undergo TST conversion. It remains unclear whether this delay in M. tuberculosis infection is related to differences in the infectious exposure, TST boosting, partial host resistance, or some other factor. We conducted a household contact study Vitória, Brazil. Between 2008 and 2013, we identified culture-positive pulmonary TB patients and evaluated their household contacts with both a TST and interferon gamma release assay (IGRA), and identified TST converters at 8-12 weeks post study enrollment. Contacts were classified as TST-positive (≥10 mm) at baseline, TST converters, or persistently TST-negative. We compared TST converters to TST-positive and to TST-negative contacts separately, using generalized estimating equations. We enrolled 160 index patients and 838 contacts; 523 (62.4%) were TST+, 62 (7.4%) TST converters, and 253 (30.2%) TST-. TST converters were frequently IGRA- at 8-12 weeks. In adjusted analyses, characteristics distinguishing TST converters from TST+ contacts (no contact with another TB patient and residence ownership) were different than those differentiating them from TST- contacts (stronger cough in index patient and contact BCG scar). The individual risk and timing of M. tuberculosis infection within households is variable and dependent on index patient, contact and environmental factors within the household, and the surrounding community. Our findings suggest a threshold effect in the risk of infection in humans.

Management of multidrug-resistant tuberculosis in human immunodeficiency virus patients

Jamil, K. F.

2018-03-01

Tuberculosis (TB) is a chronic infectious disease mainly caused by Mycobacterium tuberculosis(MTB). 10.4 million new TB cases will appear in 2015 worldwide. There were an estimated 1.4 million TB deaths in 2015, and an additional 0.4 million deaths resulting from TB disease among people living with human immunodeficiency virus (HIV). Multidrug- resistant and extensively drug-resistant tuberculosis (MDR and XDR-TB) are major public health concerns worldwide. 480.000 new cases of MDR-TB will appear in 2015 and an additional 100,000 people with rifampicin-resistant TB (RR-TB) who were also newly eligible for MDR-TB treatment. Their association with HIV infection has contributed to the slowing down of TB incidence decline over the last two decades, therefore representing one important barrier to reach TB elimination. Patients infected with MDR-TB require more expensive treatment regimens than drug-susceptible TB, with poor treatment.Patients with multidrug- resistant tuberculosis do not receive rifampin; drug interactions risk is markedly reduced. However, overlapping toxicities may limit options for co-treatment of HIV and multidrug- resistant tuberculosis.

Tuberculosis remains a major health problem in India, with 2 million new cases and 421,000 deaths each year. In this paper, we describe the spoligotyping results of 216 Mycobacterium tuberculosis culture isolates from patients with pulmonary tuberculosis in Mumbai, India. As spoligotyping data from India have rarely been described until now, and as there is limited information on the major circulating clades of M. tuberculosis, the data obtained were also compared to an international spoligotype database (SpolDB4) that contained patterns from 22,546 isolates from more than 100 countries. Eighty-four (39%) of the isolates were definitively marked as orphan strains, indicating the paucity of such data from India. The remaining 132 isolates clustered among 59 shared types; among these, 42 shared types were already present in the database, 17 were newly created, and 5 of them were specifically reported from Mumbai. A total of 9 major types in this study clustered 32% of the isolates. At the phylogenetic level, 30% of the isolates belonged to the Central Asian families CAS1 and CAS2, of the major genetic group (MGG) 1, 29% to MGG 2 and 3 families (spacers 33-36 missing) and 17% to the ancestral East African Indian (EAI) family. Finally, nearly 10% of the isolates belonged to the W-Beijing family in a broad sense, also in the MGG 1 group. In conclusion, historic clones of the MGG 1 group of M. tuberculosis are responsible for roughly 60% of all tuberculosis cases in Mumbai. Together with the fact that organisms presumably of European descent (such as the Haarlem family) were only rarely found, our observations suggest that tuberculosis in Mumbai, India is essentially caused by historical clones of tubercle bacilli undergoing active circulation due to uncontrolled demography, high prevalence of the disease, and a paucity of resources.

Full Text Available Background: Globally, the burden of Tuberculosis is escalating. Early diagnosis and prompt initiation of tuberculosis treatment is essential for an effective tuberculosis control programme. Objectives: To study the self reported reasons for patient and health system (diagnosis & treatment delays in Tuberculosis patients. Methods: A community based cross sectional study was conducted among 98 new sputum positive TB cases aged > 15 years registered under RNTCP from Oct 2006 to June 2007 & receiving treatment under DOTS in Udupi taluk by interviewing them. Results: Total 98 patients were recruited and 68% were males. Out of 17 patients with patient delays, 82% felt that their symptoms were not severe, 71% felt that patient delay was due to lack of awareness and 71% did not take it seriously. Out of 86 patients with health system delays, 82.6% of patients mentioned that doctor has not advised for sputum examination, 76.7% of patients told that they first consulted a private doctor, 21% of them mentioned that doctor was unaware to diagnose TB. Conclusion: Symptoms not severe is the main reason for the patient delay and doctor didn’t advise for sputum examination is the main reason for health system delays.

Full Text Available Deficiencies in essential trace elements are associated with impaired immunity in tuberculosis infection. However, the trace element concentrations in the serum of Korean patients with tuberculosis have not yet been investigated. This study aimed to compare the serum trace element concentrations of Korean adult patients with tuberculosis with noninfected controls and to assess the impact of serum trace element concentration on clinical outcome after antituberculosis treatment. The serum concentrations of four trace elements in 141 consecutively recruited patients with tuberculosis and 79 controls were analyzed by inductively coupled plasma-mass spectrometry. Demographic characteristics were also analyzed. Serum cobalt and copper concentrations were significantly higher in patients with tuberculosis compared with controls, while zinc and selenium concentrations were significantly lower (p < 0.01. Moreover, serum selenium and zinc concentrations were positively correlated (ρ = 0.41, p < 0.05. A high serum copper concentration was associated with a worse clinical outcome, as assessed after one month of antituberculosis therapy. Specifically, culture-positive patients had higher serum copper concentrations than culture-negative patients (p < 0.05. Patients with tuberculosis had altered serum trace element concentrations. Further research is needed to elucidate the roles of individual trace elements and to determine their clinical impact on patients with tuberculosis.

Full Text Available We report a case of 23-year-old male patient with tuberculosis verrucous cutis on the foot for a duration of six months without responding to routine treatment. Tuberculosis is a common disease worldwide. Extrapulmonary tuberculosis contributes to 10% of cases. Cutaneous tuberculosis occupies a small spectrum of extrapulmonary tuberculosis. Tuberculosis verrucosa cutis is an exogenous infection occurring in a previously sensitized patient by direct inoculation of the organism. It occurs in sensitized patients with a moderate to high immune response. The diagnosis in our patient was confirmed by history, clinical examination, histopathological examination and the patient’s response to anti-tuberculous therapy.

Kenya ranks among the twenty-two countries that collectively contribute about 80% of the world's Tuberculosis cases; with a 50-200 fold increased risk of tuberculosis in HIV infected persons versus non-HIV hosts. Contemporaneously, there is an increase in mobile penetration and its use to support healthcare throughout Africa. Many are skeptical that such m-health solutions are unsustainable and not scalable. We seek to design a scalable, pervasive m-health solution for Tuberculosis care to become a use case for sustainable and scalable health IT in limited resource settings. We combine agile design principles and user-centered design to develop the architecture needed for this initiative. Furthermore, the architecture runs on multiple devices integrated to deliver functionality critical for successful Health IT implementation in limited resource settings. It is anticipated that once fully implemented, the proposed m-health solution will facilitate superior monitoring and management of Tuberculosis and thereby reduce the alarming statistic regarding this disease in this region.

Tuberculosis and HIV/AIDS are a dangerous couple in sub-Saharan Africa. The aim of this paper is to evaluate the prevalence of the co-infection tuberculosis/HIV/AIDS and its impact on issues of tuberculosis patients treated in Lubumbashi Heath Zone (LHZ). A retrospective and transversal study was conducted through the analysis of tuberculosis patients' data admitted in the tuberculosis Health Centers for Diagnosis and treatment (HCDT) in the LHZ from January 2014 to December 2015. TB-HIV co-infection cases will be identified and the outcome will be analyzed. Data of 1368 patients were noted from three HCDT of the TB of the Lubumbashi ZS and among them 334 cases of co-infections were recorded. The most incriminated age range is 40-50 years. The mean of age of our patients is 32.84±15.32 years and the man/women sex ratio is 1.70. The most predominant clinical tuberculosis form is the extra pulmonary [EPT (52.70 %)]. Among co-infected patients, the predominant form is pulmonary (TPM-). Out of the 51 cases of deaths recorded, 23 (45.10 %) also had HIV while 28 (54.90 %) were HIV-negative. There was an increase of 11.6 % in TB-HIV/AIDS co-infection from 2014 to 2015. TB-HIV/AIDS co-infection is a reality in the LHZ, especially in patients with negative bacterial TB (TPM-) and we have to pay a particular attention on the impact of HIV on the death of tuberculosis patients.

We examined the immune responses of patients with active pulmonary tuberculosis (TB) and their healthy household contacts to short-term culture filtrate (ST-CF) of Mycobacterium tuberculosis or molecular mass fractions derived from it. Our goal was to identify fractions strongly recognized...... to the antigens between the two groups was also found. In general, while all fractions stimulated immune responses, the highest activity was seen with the low-molecular-mass fractions, which include well-defined TB antigens such as ESAT-6. Leukocytes from contacts of TB patients with severe disease produced...... higher levels of antigen-specific IFN-gamma than those from contacts of patients with minimal disease. Both groups of contacts exhibited higher cell-mediated responses than the patients themselves. The enhanced immune response of healthy contacts, especially those of patients with severe disease...

The chest radiographs of 95 patients with the new diagnosis of atypical turberculosis were reviewed to determine if any significant differences between atypical tuberculosis and that caused by Mycobacterium tuberculosis could be discerned. Findings included upper lobe involvement in B4 of the 95 patients and cavities in 76, with nearly equal groups having no, moderate, or extensive surrounding alveolar disease. Nodules were common; in six patients a nodule was the sole manifestation of disease. Adenopathy was seen in 12 of the 95 patients, atlectasis in 45, pleural thickening in 90, and effusions in three. These radiographic findings did not allow the radiographic differentiation of atypical tuberculosis from Mycobacterium tuberculosis infection

The purpose of this report is to present an update on the manifestations and management of ocular tuberculosis. Tuberculosis affects one-third of the world's population. The incidence of tuberculosis has increased with the increase in the HIV infected population. Following a resurgence of the disease in the US, the incidence has recently declined. Patients may develop scleritis that can be focal, nodular or diffuse with or without keratitis. Anterior granulomatous uveitis may occur. The posterior segment reveals vitritis, choroiditis, and can mimic serpiginous choroiditis and other entities. Patients who are immunosuppressed or HIV infected may develop active mycobacterial disease in the eye leading to rapid destruction of the ocular structures. The diagnosis of ocular tuberculosis is made by isolation of Mycobacterium tuberculosis on Löwestein-Jensen medium or by PCR. The diagnosis is supported by the clinical findings, imaging techniques including optical coherence tomography, fluorescein angiography, indocyanine green and ultrasonography. Tuberculin skin test helps to confirm the diagnosis. Ocular tuberculosis may occur in the absence of pulmonary disease. Patients present with a spectrum of clinical signs. The disease may mimic several clinical entities. Early diagnosis and prompt treatment of ocular tuberculosis may prevent ocular morbidity and blindness.

Protective immunity against Mycobacterium tuberculosis (Mtb) requires IFNG. Besides, IFNG-mediated induction of autophagy suppresses survival of virulent Mtb in macrophage cell lines. We investigated the contribution of autophagy to the defense against Mtb antigen (Mtb-Ag) in cells from tuberculosis patients and healthy donors (HD). Patients were classified as high responders (HR) if their T cells produced significant IFNG against Mtb-Ag; and low responders (LR) when patients showed weak or no T cell responses to Mtb-Ag. The highest autophagy levels were detected in HD cells whereas the lowest quantities were observed in LR patients. Interestingly, upon Mtb-Ag stimulation, we detected a positive correlation between IFNG and MAP1LC3B-II/LC3-II levels. Actually, blockage of Mtb-Ag-induced IFNG markedly reduced autophagy in HR patients whereas addition of limited amounts of IFNG significantly increased autophagy in LR patients. Therefore, autophagy collaborates with human immune responses against Mtb in close association with specific IFNG secreted against the pathogen. PMID:25426782

Pulmonary tuberculosis is one of the infectious diseases that has been known and is still the leading cause of death in the world. It is an old disease which is a global problem in the world and estimated that a third of the world's population has been infected by this bacterium. The purpose of this study was to determine the factors related with the infection prevention efforts of pulmonary tuberculosis patients in the local goverment clinic of Kuta Baro Aceh Besar. This research is descriptive analytic survey using cross sectional design. It used univariate analysis to see the frequency distribution and the percentage of each variable. Meanwhile, the bivariate analysis used chi square test with CI (Confident Interval) of 95%. The samples in this study are 34 people. The research results obtained with good infection prevention efforts of pulmonary tuberculosis is 41.2%, 5.9% for teenagers, 47.1% for knowledgeable people, 17.6% for people who do not work and 44.1% for those who have a positive behavior. The results of the bivariate obtained there is correlation between the prevention of pulmonary tuberculosis infection with age (p = 0.087), Occupation (p = 0.364), knowledge (p = 0.006) and behavior (p = 0.020). To conclude, there is a correlation between knowledge and behaviors with the infection prevention efforts of pulmonary tuberculosis patients and there is no correlation between age and occupation with infection prevention efforts of pulmonary tuberculosis patients. It is expected that the respondents to hold consultations to health officials about a mechanism of prevention to avoid the disease.

The objective of this study is to clarify clinical characteristics which differentiate bacteriologically positive pulmonary tuberculosis patients from negative ones in Mongolia. The subjects include 338 patients aged 16 years and older who had undergone bacteriological examinations. Of them, 107 patients (31.7%) were confirmed bacteriologically. The proportion of bacteriological positive results increased significantly among patients who had cavities in the roentgenographic examination, cough at diagnosis and the family history of tuberculosis. Addressing these clinical characteristics will contribute to raising not only the sensitivity of the sputum examination, but also the specificity of the roentgenographic examination in the diagnostic process of tuberculosis.

Human immunodeficiency virus (HIV)-associated tuberculosis deaths have decreased worldwide over the past decade. We sought to evaluate the effect of HIV status on tuberculosis mortality among patients undergoing treatment for tuberculosis in Lima, Peru, a low HIV prevalence setting. We conducted a prospective cohort study of patients treated for tuberculosis between 2005 and 2008 in two adjacent health regions in Lima, Peru (Lima Ciudad and Lima Este). We constructed a multivariate Cox proportional hazards model to evaluate the effect of HIV status on mortality during tuberculosis treatment. Of 1701 participants treated for tuberculosis, 136 (8.0%) died during tuberculosis treatment. HIV-positive patients constituted 11.0% of the cohort and contributed to 34.6% of all deaths. HIV-positive patients were significantly more likely to die (25.1 vs. 5.9%, P Peru started providing free antiretroviral therapy. As HIV diagnosis and antiretroviral therapy provision are more widely implemented for tuberculosis patients in Peru, future operational research should document the changing profile of HIV-associated tuberculosis mortality.

The human leukocyte antigen (HLA) system has a major role in the regulation of the immune response as it is involved in the defense against pathogens. Some studies have reported that HLA class II genes play a strong role in severe cases of pulmonary tuberculosis (PTB) in several populations. Thus the aim of the study was to compare the HLA-class II alleles of patients with drug resistant tuberculosis with those of healthy controls from the same ethnic group in Kazakhstan. The aim of the present study was to evaluate the correlation of HLA-class II alleles by patients with drug resistant tuberculosis and the healthy controls of the same ethnic group in Kazakhstan. The HLA-class II alleles of 76 patients with tuberculosis (TB) and 157 healthy volunteers were investigated using sequence-based typing (SBT)-method. HLA-DQA1*03:02 HLA-DRB1*08:01 and DRB1*08:03 occurred more frequently (P = 0.05) in patients with drug resistant tuberculosis than in controls. We observed a possible association between certain HLA alleles and TB that are specific for the Kazakh population. Further studies are needed to confirm our findings using a larger number of patients with drug resistant tuberculosis. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full Text Available Aims: Leptin is one of the most important fat-derived hormones. Several studies have shown that serum leptin levels in systemic inflammatory diseases are reduced. The aim of this study was to evaluate the serum leptin levels in three groups: patients with active pulmonary tuberculosis (TB, patients with non-pulmonary infections (acute pneumonia and normal people. Materials & Methods: In this cross-sectional study, in 2010, 40 patients with active pulmonary TB (case group and 40 patients with non-pulmonary infections (positive control group admitted to Boo-Ali hospital in Zahedan and 40 healthy subjects (negative control group were selected using easy access and serum leptin levels were evaluated by ELISA. Data were analyzed by SPSS 18 software and one-way ANOVA. Findings: The mean of serum leptin levels in patients with non-pulmonary infections (p=0.030 and in patients with active pulmonary TB (p=0.004 were significantly lower than normal group, but the mean of serum leptin levels in patients with active pulmonary TB and patients with non-pulmonary infections were not significantly different (p=0.555. Conclusion: Serum leptin levels are lower in patients with active pulmonary tuberculosis and in patients with non-pulmonary infections than in normal people, but there is no difference between patients with active pulmonary tuberculosis and patients with non-pulmonary infections. Therefore, serum leptin levels are not an appropriate marker for the differentiation of active pulmonary tuberculosis from pulmonary infections (acute pneumonia.

Background: The emergence of programmatically incurable tuberculosis threatens to destabilise control efforts. The aim of this study was to collect prospective patient-level data to inform treatment and containment strategies. Methods: In a prospective cohort study, 273 South African patients with extensively drug-resistant tuberculosis, or resistance beyond extensively drug-resistant tuberculosis, were followed up over a period of 6 years. Transmission dynamics, infectiousness, and drug susceptibility were analysed in a subset of patients from the Western Cape using whole-genome sequencing (WGS; n=149), a cough aerosol sampling system (CASS; n=26), and phenotypic testing for 18 drugs (n=179). Findings: Between Oct 1, 2008, and Oct 31, 2012, we enrolled and followed up 273 patients for a median of 20·3 months (IQR 9·6-27·8). 203 (74%) had programmatically incurable tuberculosis and unfavourable outcomes (treatment failure, relapse, default, or death despite treatment with a regimen based on capreomycin, aminosalicylic acid, or both). 172 (63%) patients were discharged home, of whom 104 (60%) had an unfavourable outcome. 54 (31%) home-discharged patients had failed treatment, with a median time to death after discharge of 9·9 months (IQR 4·2-17·4). 35 (20%) home-discharged cases were smear-positive at discharge. Using CASS, six (23%) of 26 home-discharged cases with data available expectorated infectious culture-positive cough aerosols in the respirable range (<5 μm), and most reported inter-person contact with suboptimal protective mask usage. WGS identified 17 (19%) of the 90 patients (with available sequence data) that were discharged home before the diagnosis of 20 downstream cases of extensively drug-resistant tuberculosis with almost identical sequencing profiles suggestive of community-based transmission (five or fewer single nucleotide polymorphisms different and with identical resistance-encoding mutations for 14 drugs). 11 (55%) of these downstream

Objective Onodera's Prognostic Nutritional Index (PNI), determined as “10× albumin (g/dL) + 0.005× lymphocyte count (/μL),” was originally designed to determine the risk of complications following gastrointestinal surgery. This single-center, retrospective observational study was designed to investigate whether or not the PNI can predict the treatment outcome. Methods We consecutively reviewed HIV-negative pulmonary tuberculosis adults in an isolation ward. Most patients were being treated with standard three- or four-drug regimens. Patients were discharged after consecutive negative smears/cultures were confirmed. The risk of all-cause death was assessed using a multivariable Cox proportional hazard model and a log-rank trend test. Results During the observation period, we observed 371 consecutive patients with a median age of 72 (interquartile range [IQR]: 54-82) years. In our cohort, 295 (79.5%) patients were discharged alive, and 76 (20.5%) died in-hospital. Patients who died in-hospital had a lower PNI [median 21.2 (IQR: 18.5-25.9)] than those who were discharged alive [median 35.1 (IQR: 28.0-43.3); p<0.001]. The area under the receiver operating characteristic curve was 0.87. After dividing the patients based on the baseline PNI quartile, those patients with a lower PNI showed a poorer survival than those with a higher PNI (log-rank trend p<0.001). After adjusting for other baseline variables, the baseline PNI was still associated with in-hospital death with a hazard ratio of 0.86 (95% confidence interval: 0.82-0.91, p<0.001). Conclusion Our results showed that a low PNI was clearly related to a poor survival prognosis in smear-positive HIV-negative pulmonary tuberculosis inpatients. PMID:29021438

Bronchoscopic techniques in the management of patients with tuberculosis

Full Text Available Tuberculosis (TB is one of the leading causes of morbidity and mortality worldwide. Early diagnosis and treatment are key to prevent Mycobacterium tuberculosis transmission. Bronchoscopy can play a primary role in pulmonary TB diagnosis, particularly for suspected patients with scarce sputum or sputum smear negativity, and with endobronchial disease. Bronchoscopic needle aspiration techniques are accurate and safe means adopted to investigate hilar and mediastinal lymph nodes in cases of suspected TB lymphadenopathy. Tracheobronchial stenosis represents the worst complication of endobronchial tuberculosis. Bronchoscopic procedures are less invasive therapeutic strategies than conventional surgery to be adopted in the management of TB-related stenosis.We conducted a non-systematic review aimed at describing the scientific literature on the role of bronchoscopic techniques in the diagnosis and therapy of patients with TB.We focused on three main areas of interventions: bronchoscopic diagnosis of smear negative/sputum scarce TB patients, endobronchial TB diagnosis and treatment and needle aspiration techniques for intrathoracic TB lymphadenopathy. We described experiences on bronchoalveolar lavage, bronchial washing, and biopsy techniques for the diagnosis of patients with tracheobronchial and pulmonary TB; furthermore, we described the role played by conventional and ultrasound-guided transbronchial needle aspiration in the diagnosis of suspected hilar and mediastinal TB adenopathy. Finally, we assessed the role of the bronchoscopic therapy in the treatment of endobronchial TB and its complications, focusing on dilation techniques (such as balloon dilation and airway stenting and ablative procedures (both heat and cold therapies.

How accurate are self‐reported smoking habits in patients with tuberculosis?

Directory of Open Access Journals (Sweden)

Cope GF

2017-01-01

Full Text Available Background Smoking or chewing tobacco is a global public health problem that is becoming increasingly prevalent in developing countries. These same countries often also have high rates of tuberculosis disease and infection. As smoking can adversely affect tuberculosis severity, response to treatment and relapse, it is therefore important that clinicians have an accurate picture of patients’ smoking habits. Self‐reported smoking habits may be unreliable and objective measurements of tobacco exposure more accurate. Objective To determine the reliability of self‐reported smoking habits in patients with tuberculosis by measurement of urinary cotinine levels, an objective measure of tobacco exposure. Methods Self‐reported tobacco use was recorded in 100 patients receiving treatment for active or latent tuberculosis using an interviewer administered ‘questionnaire. Urinary cotinine levels were measured by the SmokeScreen test 24hours after the end of treatment. Findings Of 81 reported non‐smokers, 10 had a positive test for cotinine, six of whom gave a result indicative of heavy (11‐15 cigarettes/day or very heavy (>16/day smoking. Of the 17 self‐confessed smokers and two chewers of tobacco, nine gave a result consistent with very heavy smoking although none had reported this degree of tobacco use. Conclusions Important discrepancies exist between subjective and objective smoking habits. Reliance on patient history may adversely affect response to tuberculosis treatment, and some patients will be denied appropriate intervention for smoking cessation.

To evaluate the CT features of pulmonary tuberculosis in diabetic or immunocompromised patients, we reviewed CT of the chest in 42 adult patients with active pulmonary tuberculosis. Forty-two had some underlying diseases or immunocompromised conditions (31 diabetes mellitus, 6 malignancies, 2 long-term steroid therapy, 2 pneumoconiosis, and one anorexia nervosa). In diabetic or immunocompromised patients, a high incidence of non-segmental distribution (27%) and multiple small cavities in a cavitary lesion (45%) was observed. Unusual localization of the lesions such as lower lung field disease was observed in 18% of cases (the incidence of unusual localization in patients with no underlying disease was equal to diabetic or immunocompromised patients).

Tuberculosis remains the single highest contributor to the world's morbidity and mortality. Early diagnosis and prompt treatment is essential to prevent its transmission. To see the treatment response of anti tuberculosis drugs in smear negative patients and study the predictors of culture positive among smear negative tuberculosis patients. Ninety four sputum smear negative patients clinically and radiologically suggestive of tuberculosis were selected. These patients were put on anti tuberculosis drugs without waiting for their culture results. They were then followed for 8 months to see their treatment outcome. A total of 94 smear negative patients were selected and given anti tuberculosis treatment. Of these 37(39%) were culture positive and 57(61%) were culture negative. Of the 37 culture positive patients 36(97%) showed clinical or radiological improvement as compared to 46(81%) out of 57 in culture negative cases. Symptoms of cough with sputum production was significantly associated with culture positivity. On x-ray chest moderate lesion with diffuse infiltration was more common finding in 64% while extensive and cavitatory lesion was seen in 24% of all cases. Association of extensive and cavitatory lesion were seen in culture positive group. Response to anti tuberculosis drugs in sputum smear negative tubercolosis suspects was found to be effective in majority of the patients. Cough, sputum and extensive cavitatory lung lesion were the predictors of culture positive cases. There is need to train physicians on the use of anti tuberculosis therapy in smear negative suspected pulmonary tuberculosis cases, especially if they have productive cough and cavitatory lung lesions.

Can follow-up examination of tuberculosis patients be simplified? A study in Chhattisgarh, India.

Directory of Open Access Journals (Sweden)

Debashish Kundu

Full Text Available BACKGROUND: Each follow-up during the course of tuberculosis treatment currently requires two sputum examinations. However, the incremental yield of the second sputum sample during follow-up of different types of tuberculosis patients has never been determined precisely. OBJECTIVES: To assess the incremental yield of the second sputum sample in the follow-up of tuberculosis patients under the Revised National Tuberculosis Control Programme (RNTCP in Chhattisgarh, India. METHODOLOGY: A record review of tuberculosis (TB patients registered in 2009 using a structured proforma from two sources, Tuberculosis and Laboratory Register, was undertaken in the six districts of Chhattisgarh, India. RESULTS: In smear positive cases, of 10,048 follow-up examinations, 45 (0.5% were found to be smear positive only on the second sputum when the result of the first sample was negative. In smear negative pulmonary and extra pulmonary TB patients, of 6,206 follow-up smear examinations, 11(0.2% were found to be smear positive. CONCLUSIONS: The incremental yield of a second smear examination was very low, indicating that examination of one sputum sample is enough during follow-up among TB patients. There is insufficient yield to support sputum smear microscopy for monitoring smear negative pulmonary TB and extra pulmonary TB patients. These results indicate that the follow-up smear microscopy can be substantially simplified with favourable resource implications.

Full Text Available There was studied the profile of drug resistance to the main (I line and reserve (II line antituberculosis drugs in patients with MDR and XDR tuberculosis, depending of the case of the disease. According to the randomized retrospective research 200 patients with MDR and XDR tuberculosis, who received treatment in the clinic of hospital Municipal institution «Dnipropetrovsk rigional clinical association «Phthisiology» Dnipropetrovsk regional Council» during the period 2010 – 2012 were involved. Data about patients contained the data on a case of the disease and the results of the test of drug sensitivity to MBT. XDR – TB was revealed in 7.5% of patients with MDR tuberculosis. In patients with MDR tuberculosis as compared with patients with XDR tuberculosis «new cases» were diagnosed in 19.5% against 18.5% (p <0.05. In patients with MDR tuberculosis and with XDR tuberculosis resistance to the antituberculosis drug more commonly developed to S - 88.5%, E - 55% and Z - 24%. The presence of MDR-TB and XDR-TB prevails in patients, who underwent previous courses of treatment with anti-TB drugs in case history as compared with patients with «new cases» of treatment. The development of resistance to anti-TB drugs depends on the availability of these drugs in the previous treatment regimens.

Backgrounds Patients who develop an active tuberculosis infection during tumor necrosis factor (TNF) inhibitor treatment typically discontinue TNF inhibitor and receive standard anti-tuberculosis treatment. However, there is currently insufficient information on patient outcomes following resumption of TNF inhibitor treatment during ongoing anti- tuberculosis treatment. Our study was designed to investigate the safety of resuming TNF inhibitors in ankylosing spondylitis (AS) patients who developed tuberculosis as a complication of the use of TNF inhibitors. Methods Through the nationwide registry of the Korean Society of Spondyloarthritis Research, 3929 AS patients who were prescribed TNF inhibitors were recruited between June 2003 and June 2014 at fourteen referral hospitals. Clinical information was analyzed about the patients who experienced tuberculosis after exposure to TNF inhibitors. The clinical features of resumers and non-resumers of TNF inhibitors were compared and the outcomes of tuberculosis were surveyed individually. Findings Fifty-six AS patients were treated for tuberculosis associated with TNF inhibitors. Among them, 23 patients resumed TNF inhibitors, and these patients were found to be exposed to TNF inhibitors for a longer period of time and experienced more frequent disease flare-up after discontinuation of TNF inhibitors compared with those who did not resume. Fifteen patients resumed TNF inhibitors during anti-tuberculosis treatment (early resumers) and 8 after completion of anti-tuberculosis treatment (late resumers). Median time to resuming TNF inhibitor from tuberculosis was 3.3 and 9.0 months in the early and late resumers, respectively. Tuberculosis was treated successfully in all resumers and did not relapse in any of them during follow-up (median 33.8 [IQR; 20.8–66.7] months). Conclusions Instances of tuberculosis were treated successfully in our AS patients, even when given concomitantly with TNF inhibitors. We suggest that early

Radiological examinations from 104 patients HIV-positive with tuberculosis were revised at HUGG/Uni-Rio, during the period from June/86 to June/89. From these, 91.4% were male patients, the predominant risk group was homosexual. Among the women, the most affected group was the intravenous drug consumer. The general age group mostly presented was the one from 20 to 39 years. The main tuberculosis confirmation came from the BAAR research in the sputum (57.6%); the necropsy contributed with 13.5% of the patients. The extrathoracic manifestations occurred in 27% of the cases. The most common radiological patterns were interstitial infiltrate 71.2%, bilateral in 48% of the cases, in the alveolar patterns 63.5%, mostly upper lobes, frequently they were simultaneous. Other important findings were: mediastinal lymphatic involvement, pleural effusion, cavity and X-ray without particularities with pulmonary tuberculosis. A comparison study was performed based on literature data and it was observed atypical patterns for the secondary tuberculosis. (author)

Full Text Available Tuberculosis (TB is a major concern in developing countries. In Brazil, few genotyping studies have been conducted to verify the number of IS6110 copies present in local prevalent strains of Mycobacterium tuberculosis, the distribution and clustering of strains. IS6110 DNA fingerprinting was performed on a sample of M. tuberculosis isolates from patients with AFB smear-positive pulmonary TB, at a hospital in Brazil. The IS6110 profiles were analyzed and compared to a M. tuberculosis database of the Houston Tuberculosis Initiative, Houston, US. Seventy-six fingerprints were obtained from 98 patients. All M. tuberculosis strains had an IS6110 copy number between 5-21 allowing for differentiation of the isolates. Human immunodeficiency virus infection was confirmed in nearly half the patients of whom data was available. Fifty-eight strains had unique patterns, while 17 strains were grouped in 7 clusters (2 to 6 strains. When compared to the HTI database, 6 strains matched isolates from El Paso, Ciudad de Juarez, Houston, and New York. Recently acquired infections were documented in 19% of cases. The community transmission of infection is intense, since some clustered strains were recovered during the four-year study period. The intercontinental dissemination of M. tuberculosis strains is suspected by demonstration of identical fingerprints in a distant country.

Case report : tuberculosis liver abscess in male alcoholism patient

A liver abscess often occurs in low-middle income countries such as Indonesia. Two most common liver abscesses are amoebic and pyogenic liver abscess. Data that reported tuberculosis liver abscess (TLA) is extremely rare. A diagnostic criterion for tuberculosis liver abscess is rare and remains unclear. A 52-year-old man developed a TLA which was not associated with any pulmonary or gastrointestinal tract foci of tuberculosis. An ultrasonogram and abdominal scan showed an abscess in the right lobe. We performed paracentesis, and the pus from the lesion was positive tubercular bacilli on acid-fast bacilli staining. The patient was started on systemic antitubercular therapy to which he responded favorably. This report emphasizes the fact that, although a TLA is a very rare entity, it should be included in the differential diagnosis of liver abscess especially in Indonesia where the prevalence of tuberculosis is extremely high.

We examined the immune responses of patients with active pulmonary tuberculosis (TB) and their healthy household contacts to short-term culture filtrate (ST-CF) of Mycobacterium tuberculosis or molecular mass fractions derived from it. Our goal was to identify fractions strongly recognized...... antigens and immune responses were determined. Household contacts produced significantly higher levels of gamma interferon (IFN-gamma) than the TB patients in response to antigens present in ST-CF and the 10 narrow-molecular-mass fractions. A similar difference in leukocyte proliferative responses...... to the antigens between the two groups was also found. In general, while all fractions stimulated immune responses, the highest activity was seen with the low-molecular-mass fractions, which include well-defined TB antigens such as ESAT-6.

Patients with pulmonary tuberculosis are likely to develop pulmonary impairment after tuberculosis (PIAT). The stability of PIAT and the relationship of PIAT to the duration of delay in tuberculosis diagnosis and treatment have not been fully characterized. We performed serial pulmonary function tests (PFTs) in a cohort treated for pulmonary tuberculosis after 20 weeks of tuberculosis therapy and again on or after treatment completion to determine the stability of PIAT. PFTs were compared with the duration of delay in tuberculosis diagnosis and treatment, as well as other demographic variables. The median duration between the first and second tests was 15 (interquartile range 9-34) weeks. The mean change in FVC was -0.02l (95% confidence interval [CI] -0.09, 0.06), and the % predicted was -0.02 (95% CI -2.17, 2.12). FEV1 changes were 0l (95% CI -0.05, 0.06), and the % predicted was -0.11 (95% CI -1.82, 1.60). PIAT was not related to the duration of delay in tuberculosis diagnosis or treatment, age or smoking. PIAT was not associated with the duration of delay in tuberculosis diagnosis and treatment and did not significantly change during follow-up. These data demonstrate that, for many individuals, the completion of tuberculosis treatment is the beginning, not the end, of their tuberculosis illness. Published by Elsevier Ltd.

Mahalingam Vasantha

Full Text Available Tuberculosis still remains a major public health problem even though it is treatable and curable. Weight gain measurement during anti tuberculosis (TB treatment period is an important component to assess the progress of TB patients. In this study, Latent Growth Models (LGMs were implemented in a longitudinal design to predict the change in weight of TB patients who were given three different regimens under randomized controlled clinical trial for anti-TB treatment. Linear and Quadratic LGMs were fitted using Mplus software. The age, sex and treatment response of the TB patients were used as time invariant independent variables of the growth trajectories. The quadratic trend was found to be better in explaining the changes in weight without grouping than the quadratic model for three group comparisons. A significant increase in the change of weight over time was identified while a significant quadratic effect indicated that weights were sustained over time. The growth rate was similar in both the groups. The treatment response had significant association with the growth rate of weight scores of the patients.

The widespread and low cost of mobile phones and the convenience of short message service (SMS) text messaging suggest potential suitability for use with alternative strategies for supporting retention in care and adherence to the treatment of various chronic diseases, such as HIV and tuberculosis (TB). Despite the growing body of literature reporting positive outcomes of SMS text message-based communication with patients, there is yet very little research about the integration of communication technologies and electronic medical records or electronic patient tracking systems. To design, develop, and implement an integrated mobile phone text messaging system used to follow up with patients with HIV and TB in treatment in Mozambique. Following the design science research methodology, we developed a Web-based system that provides support to patients. A case study involving three health care sites in Mozambique was a basis for discussing design issues for this kind of system. We used brainstorming techniques to solicit usability requirements, focus group meetings to discuss and define system architecture, and prototyping to test in real environments and to improve the system. We found six sets of system requirements that need to be addressed for success: data collection, telecommunication costs, privacy and data security, text message content, connectivity, and system scalability. A text messaging system was designed and implemented in three health facilities. These sites feed data into a central data repository, which can be used for analysis of operations and decision support. Based on the treatment schedule, the system automatically sent SMS text message appointment reminders, medication reminders, as well as motivational and educational messages to patients enrolled in antiretroviral therapy and TB treatment programs. We successfully defined the requirements for, designed, and implemented a mobile phone text messaging system to support HIV and TB treatments

Towards the end of the 19th century, Europe turned particular attention to the problem of tuberculosis, at that time the most serious social disease. In the majority of cases, pulmonary tuberculosis had a fatal outcome owing to the lack of effective drugs and methods of treatment. Due to poor sanitary conditions, particularly as regards dwellings, pulmonary tuberculosis was able to spread rapidly. Hospital departments were reluctant to admit patients suffering from tuberculosis. It was only after the discoveries of Robert Koch (bacillus tubercle in 1882) that the cause of the disease became understood and methods of treatment began to be developed. A modern sanatorium and hospital with 270 beds was erected in Hohenkrug (today Szczecin-Zdunowo) between 1915 and 1930. Patients could now be treated with modern methods, surgically in most cases. After the Second World War, pulmonary tuberculosis was still an enormous epidemiologic problem. In 1949, the Polish authorities opened a 400-bed sanatoriumin Zdunowo. The methods of treatment were not much different from pre-war practice and it was only the routine introduction of antituberculotic drugs during the fifties of the past century that brought about a radical change in the fight against tuberculosis. The growing numbers of patients with tuberculosis of the genitourinary system led to the opening in 1958 of a 40-bed specialist ward at the Tuberculosis Sanatorium in Zdunowo. It should be emphasized that the Department of Genitourinary Tuberculosis in Szczecin-Zdunowo was a historical necessity and a salvation for thousands of patients from Northern Poland. The Department totally fulfilled its social duties thanks to the commitment of many outstanding persons dedicated to helping the patients. This unit was finally closed in 1987 because the demand for surgical treatment of tuberculosis was declining concurrently with the advent of new and potent antituberculotics and falling number of new cases of genitourinary

Non-adherence to tuberculosis therapy can lead to drug resistance, prolonged infectiousness, and death; therefore, understanding what causes treatment default is important. Pakistan has one of the highest burdens of tuberculosis in the world, yet there have been no qualitative studies in Pakistan that have specifically examined why default occurs. We conducted a mixed methods study at a tuberculosis clinic in Karachi to understand why patients with drug-susceptible tuberculosis default from treatment, and to identify factors associated with default. Patients attending this clinic pick up medications weekly and undergo family-supported directly observed therapy. In-depth interviews were administered to 21 patients who had defaulted. We also compared patients who defaulted with those who were cured, had completed, or had failed treatment in 2013. Qualitative analyses showed the most common reasons for default were the financial burden of treatment, and medication side effects and beliefs. The influence of finances on other causes of default was also prominent, as was concern about the effect of treatment on family members. In quantitative analysis, of 2120 patients, 301 (14.2%) defaulted. Univariate analysis found that male gender (OR: 1.34, 95% CI: 1.04-1.71), being 35-59 years of age (OR: 1.54, 95% CI: 1.14-2.08), or being 60 years of age or older (OR: 1.84, 95% CI: 1.17-2.88) were associated with default. After adjusting for gender, disease site, and patient category, being 35-59 years of age (aOR: 1.49, 95% CI: 1.10-2.03) or 60 years of age or older (aOR: 1.76, 95% CI: 1.12-2.77) were associated with default. In multivariate analysis age was the only variable associated with default. This lack of identifiable risk factors and our qualitative findings imply that default is complex and often due to extrinsic and medication-related factors. More tolerable medications, improved side effect management, and innovative cost-reduction measures are needed to reduce

There are no recent data on the prevalence of drug-resistant tuberculosis (DR TB) in Cambodia. We aim to describe TB drug resistance amongst adults with pulmonary and extra-pulmonary TB and human immunodeficiency virus (HIV) co-infection in a national referral hospital in Phnom Penh, Cambodia. Between 22 November 2007 and 30 November 2009, clinical specimens from HIV-infected patients suspected of having TB underwent routine microscopy, Mycobacterium tuberculosis culture, and drug susceptibility testing. Laboratory and clinical data were collected for patients with positive M. tuberculosis cultures. M. tuberculosis was cultured from 236 HIV-infected patients. Resistance to any first-line TB drug occurred in 34.7% of patients; 8.1% had multidrug resistant tuberculosis (MDR TB). The proportion of MDR TB amongst new patients and previously treated patients was 3.7 and 28.9%, respectively (pCambodia may be higher than previously recognised, particularly amongst HIV-infected patients. Additional prevalence studies are needed. This study also illustrates the feasibility and utility of analysis of non-respiratory specimens in the diagnosis of TB, even in low-resource settings, and suggests that extra-pulmonary specimens should be included in TB diagnostic algorithms.

Objective: To study the serum HA and LN level in patients with pulmonary tuberculosis and their response to therapy. Methods: Serum HA and LN levels were measured with RIA in: (1) 42 patients with active pulmonary tuberculosis both before and after 2 months' therapy, (2) 40 patients with non-active pulmonary TB and 330 controls. Results: The serum HA and LN level in patients with active pulmonary tubemulosis were significantly higher than those in controls (P < 0.01 ), while no significant difference could Be found Between the levels in patients with non-active pulmonary tuberculosis and controls. The serum HA and LN level in patients with active pulmonary tuberculosis dropped after therapy, but were still higher than those in controls. Significant correlation could Be found between HA and LN levels (P<0.01). The HA and LN levels were positively correlated with severity of the disease, ESR and CRP contents. Conclusion: The measurement of serum HA and LN is valuable for early diagnosis, monitoring development and assessment of therapeutic effect in patients with pulmonary tubemulosis. (authors)

With the aim of integrating HIV and tuberculosis care in rural Kenya, a team of researchers, clinicians, and technologists used the human-centered design approach to facilitate design, development, and deployment processes of new patient-specific TB clinical decision support system for medical providers. In Kenya, approximately 1.6 million people are living with HIV and have a 20-times higher risk of dying of tuberculosis. Although tuberculosis prevention and treatment medication is widely available, proven to save lives, and prioritized by the World Health Organization, ensuring that it reaches the most vulnerable communities remains challenging. Human-centered design, used in the fields of industrial design and information technology for decades, is an approach to improving the effectiveness and impact of innovations that has been scarcely used in the health field. Using this approach, our team followed a 3-step process, involving mixed methods assessment to (1) understand the situation through the collection and analysis of site observation sessions and key informant interviews; (2) develop a new clinical decision support system through iterative prototyping, end-user engagement, and usability testing; and, (3) implement and evaluate the system across 24 clinics in rural West Kenya. Through the application of this approach, we found that human-centered design facilitated the process of digital innovation in a complex and resource-constrained context.

Full Text Available Setting. The poor patient adherence in tuberculosis (TB treatment is considered to be one of the most serious challenges which reflect the decrease of treatment success and emerging of the Multidrug Resistance-TB (MDR-TB. To our knowledge, the data about patients’ adherence to anti-TB treatment in our country are missing. Objective. This study was aimed to investigate the anti-TB treatment adherence rate and to identify factors related to eventual nonadherence among Kosovo TB patients. Design. This study was conducted during 12 months, and the survey was a descriptive study using the standardized questionnaires with total 324 patients. Results. The overall nonadherence for TB patient cohort was 14.5%, 95% CI (0.109–0.188. Age and place of residence are shown to have an effect on treatment adherence. Moreover, the knowledge of the treatment prognosis, daily dosage, side effects, and length of treatment also play a role. This was also reflected in knowledge regarding compliance with regular administration of TB drugs, satisfaction with the treatment, interruption of TB therapy, and the professional monitoring in the administration of TB drugs. Conclusion. The level of nonadherence TB treatment in Kosovar patients is not satisfying, and more health care worker’s commitments need to be addressed for improvement.

Full Text Available Background: HIV/AIDS pandemic is responsible for the resurgence of TB worldwide, resulting in increased morbidity and mortality. HIV and Mycobacterium tuberculosis have a synergistic interaction; each propagates progression of the other. Coinfection with HIV infection leads to difficulties in both the diagnosis and treatment of tuberculosis, increase risk of death, treatment failure and relapse. Objective: The aim of the present study is to study the clinical, radiological profile of pulmonary and extrapulmonary tuberculosis (EPTB in HIV-seropositive patients and their relationship to CD4 counts. Materials and Methods: It was a prospective study conducted over a period of 1 year in the department of medicine, Indira Gandhi Medical College, Shimla. We examined 87 HIV-infected patients with associated tuberculosis recruited from the department of medicine and antiretroviral center and were subjected to thorough clinical examination, X-ray chest, tuberculin testing and sputum examination for AFB and necessary relevant investigations for EPTB. Results: Most common affected age group was 31-40 years. EPTB is the commonest form of TB in our study detected in 65 patients. Commonest EPTB was CNS tuberculosis. Disseminated tuberculosis was only found in patient with CD4 count less than 200/cmm. Majority of lymph node TB was diagnosed by fine needle aspiration cytology (FNAC examination. All patients with AFB-positive lymph node had CD4 count below 200/cum. Conclusions: The results of this study provide information regarding the various forms of TB and their presentation in HIV-infected persons. Early diagnosis of tuberculosis and prompt institution of antitubercular treatment (ATT reduces mortality and morbidity significantly. In resource-poor areas, the diagnosis can be established with cytological/biochemical analysis of fluid, histopathological examination and ZN staining of tissue coupled with radiological features and response to ATT. Therefore

Exploratory Study on Plasma Immunomodulator and Antibody Profiles in Tuberculosis Patients

Science.gov (United States)

Ravindran, Resmi; Krishnan, Viswanathan V.; Khanum, Azra; Luciw, Paul A.

2013-01-01

Host immune responses to Mycobacterium tuberculosis are generally able to contain infection and maintain a delicate balance between protection and immunopathology. A shift in this balance appears to underlie active disease observed in about 10% of infected individuals. Effects of local inflammation, combined with anti-M. tuberculosis systemic immune responses, are directly detectable in peripheral circulation, without ex vivo stimulation of blood cells or biopsy of the affected organs. We studied plasma immunomodulator and antibody biomarkers in patients with active pulmonary tuberculosis (TB) by a combination of multiplex microbead immunoassays and computational tools for data analysis. Plasma profiles of 10 immunomodulators and antibodies against eight M. tuberculosis antigens (previously reported by us) were examined in active pulmonary TB patients in a country where TB is endemic, Pakistan. Multiplex analyses were performed on samples from apparently healthy individuals without active TB from the same community as the TB patients to establish the assay baselines for all analytes. Over 3,000 data points were collected from patients (n = 135) and controls (n = 37). The data were analyzed by multivariate and computer-assisted cluster analyses to reveal patterns of plasma immunomodulators and antibodies. This study shows plasma profiles that in most patients represented either strong antibody or strong immunomodulator biomarkers. Profiling of a combination of both immunomodulators and antibodies described here may be valuable for the analysis of host immune responses in active TB in countries where the disease is endemic.

By means of radiocardiography and radiometry central hemodynamic parameters were measured, using 131 I-labelled human serum albumin, pulmonary-artery systolic pressure (PASP) was assessed indirectly, and serum complement and circulating immune complexes (CIC) were measured before 48 hours after subcutaneous administration of 20 TU tuberculin in 65 patients with active pulmonary tuberculosis, 25 clinically-cured tuberculosis patients and 16 patients with chronic nonspecific pulmonary diseases (CNPD). A potent direct correlation was demonstrated between the CIC level and PASP elevation. It is suggested that close correlation between CIC and PASP elevation may be evidence of their pathogenetic involvement in chronic pulmonary heart, as well as the fact that prolonged and effective chemotherapy weakens adverse cardiovascular effects of immunologic factors, which can however persist in some individuals even after they are apparently cured from tuberculosis

To calculate excess mortality in an annual cohort of tuberculosis patients and study the factors associated with death. Cases of tuberculosis reported in Catalonia (May 1996-April 1997). Patients were classified as completed treatment/cured (compliant), non-compliant, failures, transfers out and deaths. Excess mortality was defined as the ratio actual deaths/expected deaths (according to general mortality figures for Catalonia, May 1996-April 1997). Factors associated with death were determined by a comparative study of variables (demographic, substance abuse, comorbidity, tuberculosis-related disease) in deaths after diagnosis and survivors. Time from diagnosis to death was recorded. Patients included: 2,085. Patients classified as: completed treatment/cured (compliant), 1,406 (67.43 %); noncompliant, 165 (7, 91%); failures, 5 (0.24%); transfers out, 25 (1.21%); deaths, 133 (6.38%), 28 of which occurred before diagnosis and 105 after diagnosis. Insufficient data in medical record for classification, 351 (16.83%) patients. Excess mortality: 5.98 (95% CI: 4.96-7.0). Factors associated with death: treatment with non-standardized guidelines, 46%; OR: 10.3 (6.2-17.4); HIV infection, 40%; OR: 13.0 (6.6-25.8); age greater than 64 years, 40%; OR: 14.6 (3.0-69.8); alcoholism, 25%; OR: 2.0 (1.1-3.6); neoplasm, 16%; OR: 3.9 (1.8-8.6; renal failure, 8%; OR: 10.1 (3.1-32.3). The shortest time from diagnosis to death was in patients with only one risk factor, except for HIV infection, where the time passed was the longest observed. We found substantial excess mortality in tuberculosis patients. Death was associated with the efficacy of treatment, HIV coinfection, advanced age, alcoholism and the coexistence of neoplasms or renal failure.

In Mexico, 20% of cases of tuberculosis (TB) are associated with diabetes mellitus (DM). However, the behavior of the factors related to this comorbidity is unknown, so the aim of this study was to estimate the risk factors and outcome for TB-DM in a population from the state of Veracruz, Mexico. We developed a double-design study: cases and controls for the estimation of risk factors, and a retrospective cohort for the outcome factors. The populations surveyed were 67 patients with the comorbidity TB-DB and 109 with TB. The risk factors for tuberculosis in the diabetic population studied were: age ≥ 35 with an OR of 2.5 (95% CI: 1.4-4.3) and IMC ≥ 25 with an OR of 8.5 (95% CI: 3.1-23.3). According to the outcome variables, the patients with TB-DM showed an increased risk of 2.8 (95% CI: 2.2-3.4) for the development of drug resistance against tuberculosis. In conclusion, age and overweight are important risk factors, and drug resistance is an important outcome factor for the binomial TB-DM in the population from Veracruz. This information will have important effects on the development of surveillance programs against TB, with emphasis on the characteristics of the diabetic population.

Full Text Available Tuberculosis (TBC is an dangerous disease and many people has been infected. One of many important steps to control TBC effectively and efficiently is by increasing case finding using right method and accurate diagnostic. One of them is to detect Mycobacterium Tuberculosis inside sputum. Conventional detection of Mycobacterium Tuberculosis inside sputum can need a lot of time, so digitally detection method of Mycobacterium Tuberculosis was designed as an effort to get better result of detection. This method was designed by using combination between digital image processing method and Neural Network method. From testing report that was done, Mycobacterium can be detected with successful value reach 77.5% and training error less than 5%.

T Cell Reactivity against Mycolyl Transferase Antigen 85 of M. tuberculosis in HIV-TB Coinfected Subjects and in AIDS Patients Suffering from Tuberculosis and Nontuberculous Mycobacterial Infections

Directory of Open Access Journals (Sweden)

2011-01-01

Full Text Available The mycolyl transferase antigen 85 complex is a major secreted protein family from mycobacterial culture filtrate, demonstrating powerful T cell stimulatory properties in most HIV-negative, tuberculin-positive volunteers with latent M.tuberculosis infection and only weak responses in HIV-negative tuberculosis patients. Here, we have analyzed T cell reactivity against PPD and Ag85 in HIV-infected individuals, without or with clinical symptoms of tuberculosis, and in AIDS patients with disease caused by nontuberculous mycobacteria. Whereas responses to PPD were not significantly different in HIV-negative and HIV-positive tuberculin-positive volunteers, responses to Ag85 were significantly decreased in the HIV-positive (CDC-A and CDC-B group. Tuberculosis patients demonstrated low T cell reactivity against Ag85, irrespective of HIV infection, and finally AIDS patients suffering from NTM infections were completely nonreactive to Ag85. A one-year follow-up of twelve HIV-positive tuberculin-positive individuals indicated a decreased reactivity against Ag85 in patients developing clinical tuberculosis, highlighting the protective potential of this antigen.

A recent tuberculosis prevalence survey in Kenya found that the country is home to nearly twice as many patients with tuberculosis as previously estimated. Kenya has prioritized identifying and treating the unnotified or missing cases of tuberculosis. This requires a better understanding of patient care seeking and system weaknesses. A patient-pathway analysis (PPA) was completed to assess the alignment between patient care seeking and the availability of tuberculosis diagnostic and treatment services at the national level and for all 47 counties at the subnational level in Kenya. It was estimated that more than half of patients initiate care in the public sector. Nationally, just under half of patients encountered tuberculosis diagnostic and treatment capacity where they initiated care. Overall, there was distinct variation in diagnostic and treatment availability across counties and facility levels. The PPA results emphasized the need for a differentiated approach to tuberculosis care, by county, and the distinct need for better referral systems. The majority of Kenyans actively sought care; improving diagnostic and treatment capacity in the formal and informal private sector, as well as in the public sector, could help identify the majority of missing cases. © The Author 2017.

Much of the pronounced host inflammatory response that occurs in tuberculosis (TB) is related to failed immunity against the invading pathogen. The G-protein coupled receptors CXCR1 and CXCR2 are implicated in important signal transduction pathways in lung inflammatory responses. We investigated the expression and function of these receptors in a simple whole blood model from 24 patients with pulmonary TB and in subjects with latent TB infection (LTBI). Healthy controls were recruited from close contacts to the pulmonary index patients. We found that pulmonary TB patients had significantly increased CXCR1 expression on blood cells compared to LTBI subjects and controls (p microRNA-223 was increased in pulmonary TB patients compared to LTBI (p tuberculosis (Mtb).

Full Text Available Antimicrobial therapy may cause changes in the resident oral microbiota, with the increase of opportunistic pathogens. The aim of this study was to compare the prevalence of Candida, Staphylococcus, Pseudomonas and Enterobacteriaceae in the oral cavity of fifty patients undergoing antibiotic therapy for pulmonary tuberculosis and systemically healthy controls. Oral rinsing and subgingival samples were obtained, plated in Sabouraud dextrose agar with chloramphenicol, mannitol agar and MacConkey agar, and incubated for 48 h at 37ºC. Candida spp. and coagulase-positive staphylococci were identified by phenotypic tests, C. dubliniensis, by multiplex PCR, and coagulase-negative staphylococci, Enterobacteriaceae and Pseudomonas spp., by the API systems. The number of Candida spp. was significantly higher in tuberculosis patients, and C. albicans was the most prevalent specie. No significant differences in the prevalence of other microorganisms were observed. In conclusion, the antimicrobial therapy for pulmonary tuberculosis induced significant increase only in the amounts of Candida spp.

The screening of latent tuberculosis infection (LTBI) is necessary to prevent infection in patients with chronic inflammatory disease (CID) undergoing biological treatment. We aimed to assess the efficacy of LTBI screening prior to biological treatment in Tunisia, considered as a high-incidence area of active TB disease. We conducted a retrospective study over a period of 8 years [2007-2014] including patients with chronic inflammatory rheumatism receiving biologic agents since at least 6 months. The screening of LTBI was performed according to national Tunisian guidelines. There were 35 men and 78 women. The mean age was 47.67±13.50 years. Rheumatoid arthritis (70.8%) was the most common cause of CID. The diagnosis of LTBI was established in 23 cases. Among these 23 patients, 12 patients had negative tuberculin skin test (TST) associated with positive QuantiFERON-TB Gold (QFT-G), 10 had TST more than 10mm, one patient had a TST between 5 and 10mm associated with positive QFT-G and one patient had a history of tuberculosis inadequately treated. Preventive anti-tuberculous therapy was prescribed before biological therapy initiation in cases of LTBI. During the follow-up period (3.91 years), no case of tuberculosis reactivation has been reported among patients diagnosed with LTBI. However, 2 cases of active pulmonary tuberculosis were reported in patients with initially negative TST and QFT-G. Our study showed that the Tunisian recommendations allowed detecting a LTBI in 20% of biologic therapy candidates. Preventive measures including screening of LTBI and eventually a prophylactic treatment improve the safety of biological treatments.

We established the relationship between disease severity or wasting during pulmonary tuberculosis and nutrient intake. Methods In a cross-sectional study of 131 adults with or without pulmonary tuberculosis were screened for human immune-deficiency virus (HIV, wasting, disease severity using 13 item validated clinical TBscore, and 24-hour dietary intake recall. Results Of the 131 participants, 61 were males and 70 females. Overall men and women had similar age. In average 24-hour nutrient intake, the following nutrients: energy, protein, total fat, carbohydrate, calcium, vitamin A, and folate were low among patients with severe tuberculosis disease. Patients with moderate-to-severe clinical TBscore had lower average energy intake than patients with mild TBscores (6.11 vs. 9.27 MJ, respectively (p Conclusions Findings suggest that severity of pulmonary tuberculosis and female gender had reduced nutrient intake. Early tuberculosis diagnosis and nutritional support may be important in management of tuberculosis patients.

To determine the prevalence of tuberculosis (TB) infection and disease among pediatric household contacts of patients with pulmonary TB (PTB). Cross-sectional study. One hundred and fifty-three children aged 0-15 years in the households of 62 bacteriologically confirmed PTB patients, including 44 with MDR-TB, were studied. BCG scars were noted, and tuberculin skin test (TST), screening chest radiography, and sputum or gastric aspirate smear and culture for Mycobacterium tuberculosis in those with radiographic findings suggestive of PTB were done. For children in this study, the prevalences of latent TB infection (LTBI), radiographically diagnosed pulmonary TB, and bacillary pulmonary TB were 69.2%, 3.3%, and 0.65%, respectively. Only age > or = 5 years was found to be a significant predictor of LTBI (OR 3.17, 95%CI 1.43-7.01). Contact investigation for active case-finding and early treatment of TB in children from households of patients with active PTB is essential for TB control. Further study on a more precise definition of TB infection and strategies for control in this population will be pursued.

Tuberculosis is the most common infectious complication in HIV infected patients. The incidence of tuberculosis and the proportion of disseminated disease increase with more severe immuno-suppression. Septic shock and multiple organ failure are uncommon but are of markedly bad prognostic significance. A forty-four year old HIV seropositive man was admitted to the intensive care unit (ICU) with acute respiratory distress. The patient had been febrile for the previous two weeks. His thoracic radiograph showed a discrete interstitial infiltrate and at bronchoscopy small whitish granulations were observed in the main bronchi. All bacteriological investigations remained negative at the time of ICU admission. The patient died sixteen hours later due to multiple organ failure. Mycobacteria were identified after patient's death on the smear from BAL, from blood cultures, and in a postmortem liver biopsy. Septic shock is an infrequent complication of disseminated tuberculosis. Mortality is very high. Treatment should be started early in cases with a high diagnostic suspicion.

Full Text Available Background. Although tuberculosis (TB is a major health problem worldwide, primary extrapulmonary tuberculosis (EPTB, and in particular female genital tract infection, remains a rare event. Case Report. A 35-year-old human immunodeficiency virus (HIV seropositive woman of African descent with lower abdominal pain and fever of two days duration underwent surgery due to left adnexal mass suggesting pelvic inflammatory disease. The surgical situs showed a four quadrant peritonitis, consistent with the clinical symptoms of the patient, provoked by a tuboovarian abscess (TOA on the left side. All routine diagnostic procedures failed to determine the causative organism/pathogen of the infection. Histopathological evaluation identified a necrotic granulomatous salpingitis and specific PCR analysis corroborated Mycobacterium tuberculosis (M. Tb. Consequently, antituberculotic therapy was provided. Conclusion. In the differential diagnosis of pelvic inflammatory disease, internal genital tuberculosis should be considered. Moreover, physicians should consider tuberculous infections early in the work-up of patients when immunosuppressive conditions are present.

To explore the expression of high mobility group box-1 (HMGB1) in the lung tissue and serum of patients with pulmonary tuberculosis and to explore its relationship with tumor necrosis factor (TNF)-α and interleukin(IL)-1β. Sixty samples of lung tissues were obtained from patients with pulmonary tuberculosis who had underwent pneumonectomy in Department of Chest Surgery, First Affiliated Hospital of Zunyi Medical College from June 2010 to December 2011. At the same period, 40 normal lung samples were also obtained from patients with pulmonary contusion and lung cancer by surgical resections as the control group. The mRNA expressions of HMGB1 was detected by reverse transcription-polymerase chain reaction (RT-PCR), and the protein level of HMGB1 was measured by immunohistochemical staining of tissue microarrays in lung tissue. Blood samples were taken from 89 patients with active pulmonary tuberculosis (pulmonary tuberculosis group), including hematogenous disseminated pulmonary tuberculosis (type II) in 35 cases and secondary pulmonary tuberculosis (type III) in 54 cases, and 50 healthy volunteers (control group). Furthermore, the 54 patients with secondary pulmonary tuberculosis were divided into different subgroups according to cavity formation and the lung fields involved: patients without lung cavity (35 cases) vs those with lung cavity (19 cases), patients with involvement of pulmonary tuberculosis (69 ± 29) was significantly higher than that in normal lung tissue (22 ± 12) (t = 2.389, P pulmonary tuberculosis (786 ± 86) was significantly higher than that in normal lung tissue (202 ± 60) (t = 3.872, P pulmonary tuberculosis group were (5.0 ± 3.2) µg/L, (118 ± 77) ng/L and (33 ± 20) ng/L, respectively, which were significantly higher than those in the control group [(1.7 ± 1.0) µg/L, (40 ± 11) ng/L and (18 ± 12) ng/L, respectively], the respective t values being -0.928, 4.268 and 11.064, all P pulmonary tuberculosis, the serum concentration of HMGB

Full Text Available Specific features of psychological state were studied in 295 pulmonary tuberculosis patients with satisfactory tolerance to anti-tuberculosis medications and 75 patients poorly tolerating the treatment.Before the treatment start the patients who later demonstrated adverse reactions to treatment were diagnosed with more intense neurotic and hypochondriac personal features, destructive reactions and higher level of emotional tension and frustration – all the above promote dysregulation of the host adaptation. The research demonstrated the need to consider psychological aspects when studying the tolerance to anti-tuberculosis chemotherapy.

Summary The depression of cellular immunity among diabetic patients exposes them to tuberculosis considered as one of the major diseases of immune-depressive people. The purpose of our study was to evaluate the frequency, gravity, treatment and evolution of pulmonary tuberculosis among our patients affected with diabetes. For that purpose, two descriptive retrospective and prospective studies were undertaken from January 1982 to December 1992 in the Internal Medicine (Internal medicine) department of Hospital of Point G, the national hospital. Thus, 54 diabetics patients hospitalised out of 1 365 had tuberculosis at a frequency rate of 3,95%. The average age of our patients was 49 years +/- 12 and the sex ratio was 2,18 in favour of men. The infection was also more frequent in diabetes type 1 (51,9%) then in type 2 (48,1%), and concerned mainly men (68.51%) who were more than 37 years old (57.41%). Clinically, the common signs to both affections were prevalent namely asthenia: 85,2%, anorexia: 53,7%, weight loss: 66,7%, associated to cough: 81,5% and to dyspnea: 29,6%. However, for a third of the patients (22,2%), tuberculosis was discovered during a systematic check up. All the patients had a glycemia higher than 8mmol/l, with extremes up to 8mmol/l and 32mmol/l, 63% of patient had a febricula. The intradermo cutaneous reaction to tuberculosis (IDR) was negative in 44,4%. The bacilloscopy during direct testing or through the liquid obtained by casing was positive in 64,82%. Tubercular lesions were localised at the top: 91,8%, with an equal attack of the two lungs. During the treatment six products were mainly used comprising Rifampicine (R) isoniazid (INH or H), Streptomycine (S), Ethambutol (E), Thiacetazone (T), and Pyrazinamide (Z). Insulin treatment was done on all patients until tuberculosis was cured. The evolution was favourable after 2 to 3 months of treatment for 48 patients (88,88%) among whom 4: (8,33%) fell sick again. Six patients out of 54 died, i

Full Text Available Objective: Inelaborate use of new quinolones with strong anti-tuberculosis (TB activity leads to difficulty in diagnosis and more importantly, quinolone-resistant Mycobacterium tuberculosis. We aimed to determine the frequency of quinolone use in patients who were referred to our hospital for suspected TB and to evaluate the association between quinolone use and different clinical laboratory parameters. Methods: Between November 15 and December 15, 2013, all patients who were admitted to the TB outpatient clinic with no previous diagnosis of TB were included in this study. Demographic and clinical laboratory findings and history of antibiotic use were recorded. Patients’ quinolone use were questioned by showing fluoroquinolone antibiotic boxes’ photographs available on the market. The departments of the doctors who prescribed quinolones were recorded. Results: The mean age of 179 patients included in the study was 37±16 (15–89 years. Among these, 113 patients (63.1% were male. Seventy five patients (41.9% were diagnosed as tuberculosis according to the clinical-radiological and/or bacteriological findings. Of 179 patients, 58.1% (n=104 had been prescribed antibiotics for current complaints before referral to our clinic. Sixteen patients (15% had been recommended fluoroquinolones. Fluoroquinolones were prescribed by seven internal medicine specialists, five pulmonologists, three emergency medicine specialists, and one family medicine practitioner. Among 16 fluoroquinolones prescribed, nine were moxifloxacin, four were levofloxacin, and three were gemifloxacin. Quinolone use revealed a significant inverse relationship only with the presence of hemoptysis (p=0.04. Conclusion: Besides increased educational activities regarding the rational use of antibiotics in recent years, the quinolone group of antibiotics is still prescribed for suspected TB cases. To avoid quinolone-resistant M. tuberculosis strains, further education is required.

We used computerized tomography (CT) in the study of eight patients with macronodular splenic tuberculosis prior to the microbiological diagnosis. These patients underwent additional CT controls during and after tuberculostatic therapy. All the patients studed presented the acquired immunodeficiency syndrome (AIDS). Splenomegaly and numerosous round, hypodense lesions that showed no contrast uptake were found in all the subjects. Only three patients presented evidence of tuberculosis in plain radiography and/or chest X-ray. Two patients presented abdominal lymph nodes. None of them showed evidence of hepatic lesions or ascites. follow-up CT scans revealed a progressive reduction of the lesions, which eventually disappeared completely, and splenomegaly was considerably reduced. Anthough it is uncommon, we should suspect splenic involvement in tuberculosis if the clinical and radiological contexts are appropriate. CT provides excellent monitoring of the efficacy of treatment in these patients. 17 refs

To evaluate the CT findings of pulmonary tuberculosis in patients with diabetes mellitus (MD),according to the diabetic control state. Materials and Methods: We retrospectively studied 34 cases of pulmonary tuberculosis accompanied by DM. We divided the right lung three lobes and ten segments and the left into two lobes and eight segments and analyzed CT findings of bronchogenic spread, cavitary lesion, ill-defined nodule, lobular consolidation, lobar and segmental consolidation, atelectasis, interlobular septal thickening, fibrotic band, and associated findings such as lymph node enlargement, pleural effusion and empyema. We also tried to determine the typical CT findings of pulmonary tuberculosis according to diabetic duration and controlled state of DM focusing by FBS 160 and HbA1C 8.0. Results: Among 34 CT scans, bronchogenic spread was seen on 29 (85.3%), cavitary lesion on 26 (76.5%), ill-defined nodules on 11 (32.4%), lobular consolidation on 14 (41.2%), lobar and segmental consolidation on 12 (35.3%), atelectasis on four (14.7%), and fibrotic band on eight (23.5%). Multiple cavities were present in 76.9% of total cavitary lesions, and consolidation with bronchogenic spread in 75%; associated findings were as follows: lymph node enlargement (n=1), pleural effusion (n=10), empyema (n=2), and pericardial effusion (n=2). In 46.7% of cases, general tubercular lesions were in an unusual location, but among cases of secondary pulmonary tuberculosis, 73.9% of lesions were in the usual location. More lobular consolidation was seen in patients with less than FBS 160 on admission, and this result was statistically significant (p<0.05); CT findings did not, however, differ according to diabetic duration and HbA1C. Conclusion: In patients with DM,general fubercular lesions were found infrequently, but in secondary tubereulosis, multiple cavitary lesions-in the usual location-were very frequent. In patients with DM, CT findings of pulmonary tuberculosis did not vary

Full Text Available Introduction: Case finding in tuberculosis is known to be influenced by factors such as patient motivation, care seeking, the degree of diagnostic suspicion by health care provider which could result in a delayed diagnosis.Objective: To determine care seeking behaviour and delay in diagnosis and treatment of new sputum positive tuberculosis patients registered under RNTCP.Material and Methods: Descriptive cross sectional study. 283 new sputum positive tuberculosis patients (≥15 years of age registered during a period of six months at two randomly selected tuberculosis unit of Pune city. Questionnaire by WHO was modified and used. Interviews were conducted in DOT centres. Statistical analysis: Frequency, mean and standard deviation, chi square test.Results: Mean age of patients was 35 (±15 years18% of patients were unemployed and 77% resided in urban slums. The commonest co morbidity in 7.4% and 3.5 % patients was HIV/ AIDS followed by diabetics respectively. Majority of the patients, for the first and second time visited a general practitioner. Median patient, health care system and total delay were 18, 22 and 47 days with mean of 24±21, 32±30 and 56±33 days respectively. Health care system delay was less (p<0.05 in patients who first visited the public health care facility than patients who first visited a private health care provider.Conclusions: General practitioners are preferred first choice of health care provider for tuberculosis patients. Mean health care system delay is more than patient delay.

TUBERCULOSIS INFECTION MIGHT INCREASE THE RISK OF INVASIVE CANDIDIASIS IN AN IMMUNOCOMPETENT PATIENT

Directory of Open Access Journals (Sweden)

Xiao-Hua CHEN

2015-06-01

Full Text Available Deep Candida infections commonly occur in immunosuppressed patients. A rare case of a multiple deep organ infection with Candida albicans and spinal tuberculosis was reported in a healthy young man. The 19-year-old man complained of month-long fever and lower back pain. He also had a history of scalded mouth syndrome. Coinfection with Mycobacterium tuberculosis and Candida albicans was diagnosed using the culture of aspirates from different regions. Symptoms improved considerably after antifungal and antituberculous therapy. This case illustrates that infection with tuberculosis might impair the host's immune system and increase the risk of invasive candidiasis in an immunocompetent patient.

Rational design of diagnostic and vaccination strategies for tuberculosis

Directory of Open Access Journals (Sweden)

Sibele Borsuk

Full Text Available The development of diagnostic tests which can readily differentiate between vaccinated and tuberculosis-infected individuals is crucial for the wider utilization of bacillus Calmette-Guérin (BCG as vaccine in humans and animals. BCG_0092 is an antigen that elicits specific delayed type hypersensitivity reactions similar in size and morphological aspects to that elicited by purified protein derivative, in both animals and humans infected with the tubercle bacilli. We carried out bioinformatics analyses of the BCG_0092 and designed a diagnostic test by using the predicted MHC class I epitopes. In addition, we performed a knockout of this gene by homologous recombination in the BCG vaccine strain to allow differentiation of vaccinated from infected individuals. For that, the flanking sequences of the target gene (BCG_0092were cloned into a suicide vector. Spontaneous double crossovers, which result in wild type revertants or knockouts were selected using SacB. BCG_0092 is present only in members of the Mycobacterium tuberculosis complex. Eight predicted MHC class I epitopes with potential for immunological diagnosis were defined, allowing the design of a specific diagnostic test. The strategy used to delete the (BCG_0092 gene from BCG was successful. The knockout genotype was confirmed by PCR and by Southern blot. The mutant BCG strain has the potential of inducing protection against tuberculosis without interfering with the diagnostic test based on the use of selected epitopes from BCG_0092.

Objective: To investigate CT characteristics of pulmonary tuberculosis by analyzing the reasons of misdiagnosis in 35 patients with pulmonary tuberculosis. Methods: The patients in this study included 19 men and 16 women, with ages ranging from 18 to 79 years old. Chest CT scans were performed in all patients. The CT films were reviewed retrospectively by two senior radiologists and were correlated with pathologic findings. The misdiagnosing reasons were analyzed. Results: Misdiagnoses as lung cancer were made in 29 cases, pneumonia in 4 cases, and other diseases in 2 cases. The lesions on CT films appeared as nodules and masses in 14 cases, pulmonary segmental and lobar shadows in 19 cases, and hilar and mediastinal masses in 2 cases. Conclusion: The main causes of misdiagnosis for pulmonary tuberculosis are atypical radiological appearance on CT films, inadequate visualized lesions, and lacking of combination of CT findings with that of chest radiography

Chromoblastomycosis is caused by dematiaceous fungi. It develops after inoculation of the organism into the skin. We report a case of chromoblastomycosis in a pulmonary tuberculosis patient without known history of trauma. The lesions were initially diagnosed as sporotrichosis and skin tuberculosis. Histopathology of scales and skin biopsy specimen revealed sclerotic bodies, the hallmark of chromoblastomycosis. The causative organism was identified as Fonsecaea monophora by rDNA ITS sequencing. The lesions recovered markedly after two month treatment with oral terbinafine 250 mg daily according to drug sensitive test in vitro in combination with local thermotherapy.

Cardiac tamponade is a medical emergency condition. Rapid diagnosis and determination of the etiology with epidemiologic consideration may lead to earlier treatment and improved survival. Occasionally, the etiology may be clearly related to a recognized underlying disease, but the possibility of unrelated etiologies should be considered. Pericarditis tuberculosis, a rare manifestation of extrapulmonary tuberculosis in a non-HIV patient, has to be deliberate as one of the etiology, especially in the endemic area. Here, we report a case of 28 years old male with β thalassemia major presented with excessive exertion breathlessness progressing to orthopnea. Sign of cardiac tamponade was identified from echocardiography which showed large pericardial effusion with swinging heart and right atrial systolic collapse. Pericardiocentesis was performed immediately, drained 870 ml of hemorrhagic fluid from inserted pigtail. The patient was treated with the anti-tuberculosis regimen and oral corticosteroid after real-time polymerase chain reaction of Mycobacterium tuberculosis positivity in pericardial fluid. MRI T2 confirmed no haemosiderosis in patient’s heart. After treatment, the patient responded well and showed clinical improvement.

Full Text Available Abstract Background HIV and tuberculosis (TB are commonly associated. Identifying latent and asymptomatic tuberculosis infection in HIV-positive patients is important in preventing death and morbidity associated with active TB. Methods Cross-sectional study of one time use of an interferon-gamma release assay (T-SPOT.TB - immunospot to detect tuberculosis infection in patients in a UK inner city HIV clinic with a large sub-Saharan population. Results 542 patient samples from 520 patients who disclosed their symptoms of TB were tested. Median follow-up was 35 months (range 27-69. More than half (55% originated from countries with medium or high tuberculosis burden and 57% were women. Antiretroviral therapy was used by 67%; median CD4 count at test was 458 cells/μl. A negative test was found in 452 samples and an indeterminate results in 40 (7.4% but neither were associated with a low CD4 count. A positive test was found in 10% (50/502 individuals. All patients with positive tests were referred to the TB specialist, 47 (94% had a chest radiograph and 46 (92% attended the TB clinic. Two had culture-positive TB and a third individual with features of active TB was treated. 40 started and 38 completed preventive treatment. One patient who completed preventive treatment with isoniazid monotherapy subsequently developed isoniazid-resistant pulmonary tuberculosis. No patient with a negative test has developed TB. Conclusions We found an overall prevalence of latent TB infection of 10% through screening for TB in those with HIV infection and without symptoms, and a further 1% with active disease, a yield greater than typically found in contact tracing. Acceptability of preventive treatment was high with 85% of those with latent TB infection eventually completing their TB chemotherapy regimens. IGRA-based TB screening among HIV-infected individuals was feasible in the clinical setting and assisted with appropriate management (including preventive

Purpose: To evaluate the various radiological abnormalities in patients with proven esophageal tuberculosis. Material and Methods: The case records of 23 patients with proven esophageal tuberculosis were evaluated retrospectively for various radiological abnormalities. Twenty-two patients had secondary involvement of esophagus in the form of direct extension of mediastinal and pulmonary tuberculosis or spinal tuberculosis. Only 1 patient had primary involvement of the esophagus with no evidence of disease elsewhere. The diagnosis was confirmed by endoscopic and CT-guided biopsy/aspiration cytology in 7 and 6 cases, respectively. Diagnosis was made on the basis of surgical biopsy of lymph node and autopsy in 1 patient each. In the remaining 8 patients the diagnosis was based on radiological and endoscopic findings and the response to antituberculous treatment. Results: Chest radiography (CXR) was abnormal in 65% patients. While the findings were non-conclusive for esophageal tuberculosis, characteristic lesions of tuberculosis in lungs or spine were suggestive of tuberculous etiology. In 15 patients, CT of the chest confirmed the corresponding CXR findings and also showed additional findings of mediastinal lymphadenopathy when CXR was normal. Fourteen patients showed mediastinal lymphadenopathy on CT of the chest. In all these patients, more than one group of lymph nodes was involved. The characteristic hypodense center of lymph nodes suggestive of tuberculosis was seen in 12 patients. Radiological abnormalities seen in barium swallow examination were extrinsic compression, traction diverticula, strictures, sinus/fistulous tracts, kinking and pseudotumor mass of esophagus in decreasing order of frequency. The middle third of the esophagus was found to be the most frequent site of involvement

When doctors see more cases of patients with tell-tale symptoms of a disease, it is hoped that they will be able to recognize an infection administer treatment appropriately, thereby speeding up recovery for sick patients. We hope that our studies can aid in the detection of tuberculosis by using a computer model called an artificial neural network. Our model looks at patients with and without tuberculosis (TB). The data that the neural network examined came from the following: patient' age, gender, place, of birth, blood type, Rhesus (Rh) factor, and genes of the human Leukocyte Antigens (HLA) system (9q34.1) present in the Major Histocompatibility Complex. With availability in genetic data and good research, we hope to give them an advantage in the detection of tuberculosis. We try to mimic the doctor's experience with a computer test, which will learn from patient data the factors that contribute to TB.

Full Text Available Tuberculosis is still a significant health problem in the world, mostly in developing countries. The special significance lies in immunocompromised patients, particularly those suffering from the HIV. Urogenital tuberculosis is one of the most common forms of extrapulmonary tuberculosis, while the most commonly involved organ is the kidney. Renal tuberculosis occurs by hematogenous dissemination of mycobacterium tuberculosis from a primary tuberculosis foci in the body. Tuberculosis is characterized by the formation of pathognomonic lesions in the tissues - granulomata. These granulomata may heal spontaneously or remain stable for years. In certain circumstances in the body associated with immunosuppression, the disease may be activated. Central caseous necrosis occurs within tuberculoma, leading to formation of cavities that destroy renal parenchyma. The process may gain access to the collecting system, forming the caverns. In this way, infection can be spread distally to renal pelvis, ureter and bladder. Scaring of tissue by tuberculosis process may lead to development of strictures of the urinary tract. The clinical manifestations are presented by nonspecific symptoms and signs, so tuberculosis can often be overlooked. Sterile pyuria is characteristic for urinary tuberculosis. Dysuric complaints, flank pain or hematuria may be presented in patients. Constitutional symptoms of fever, weight loss and night sweats are presented in some severe cases. Diagnosis is made by isolation of mycobacterium tuberculosis in urine samples, by cultures carried out on standard solid media optimized for mycobacterial growth. Different imaging studies are used in diagnostics - IVU, CT and NMR are the most important. Medical therapy is the main modality of tuberculosis treatment. The first line anti-tuberculosis drugs include isoniazid, rifampicin, pyrazinamide and ethambutol. Surgical treatment is required in some cases, to remove severely damaged kidney, if

2007-01-01

The radiologic knowledge of tuberculosis-associated lung disease is an essential tool in the clinical diagnosis of tuberculosis. Chest radiography is the primary imaging method, but the importance of CT is still increasing, as CT is more sensitive in the detection of cavitation, of hilar and mediastinal lymphadenopathie, of endobronchial spread and of complications in the course of the disease. In addition, CT has been proven as a valuable technique in the assessment of tuberculosis activity, especially in patients where M. tuberculosis has not been detected in the sputum or in patients with multidrug-resistant tuberculosis. Depending on the immune status of the patient, the morphologic spectrum of tuberculosis is quite variable. Early diagnosis of tuberculosis is essential to prevent further spread of the disease.

Full Text Available Introduction The primary strategy for tuberculosis control involves identifying individuals with latent tuberculosis. This study aimed to estimate the prevalence of latent tuberculosis in chronic kidney disease (CKD patients who were undergoing hemodialysis in Campo Grande, State of Mato Grosso do Sul, Brazil, to characterize the sociodemographic and clinical profiles of patients with latent tuberculosis, to verify the association between sociodemographic and clinical characteristics and the occurrence of latent tuberculosis, and to monitor patient adherence to latent tuberculosis treatment. Methods This epidemiological study involved 418 CKD patients who were undergoing hemodialysis and who underwent a tuberculin skin test. Results The prevalence of latent tuberculosis was 10.3%. The mean patient age was 53.43±14.97 years, and the patients were predominantly men (63.9%. The population was primarily Caucasian (58.6%; half (50% were married, and 49.8% had incomplete primary educations. Previous contact with tuberculosis patients was reported by 80% of the participants. Treatment adherence was 97.7%. Conclusions We conclude that the prevalence of latent tuberculosis in our study population was low. Previous contact with patients with active tuberculosis increased the occurrence of latent infection. Although treatment adherence was high in this study, it is crucial to monitor tuberculosis treatment administered to patients in health services to maintain this high rate.

Tuberculosis, more than any other infectious disease, has always been a challenge, since it has been responsible for a great amount of morbidity and mortality in humans. After a steady decline in the number of new cases during the twentieth century, due to improved social and environmental conditions, early diagnosis, and the development of antituberculous medication, a stagnation and even an increase in the number of new cases was noted in the mid-1980s. The epidemiological alteration is multifactorial: global increase in developing countries; minority groups (HIV and other immunocompromised patients); and elderly patients due to an altered immune status. Other factors that may be responsible are a delayed diagnosis, especially in elderly patients, incomplete or inadequate therapy, and the emergence of multidrug-resistant tuberculosis. The course of the disease and its corresponding clinicoradiological pattern depends on the interaction between the organism and the host response. Classically, pulmonary tuberculosis has been classified in primary tuberculosis, which occurred previously in children, and postprimary tuberculosis, occurring in adult patients. In industrialized countries, however, there seems to be a shift of primary tuberculosis towards adults. Furthermore, due to an altered immunological response in certain groups, such as immunocompromised and elderly patients, an atypical radioclinical pattern may occur. The changing landscape, in which tuberculosis occurs, as well as the global resurgence, and the changed spectrum of the clinical and radiological presentation, justify a renewed interest of radiologists for the imaging features of pulmonary tuberculosis. This article deals with the usual imaging features of pulmonary tuberculosis as well as the atypical patterns encountered in immunodepressed and elderly patients. (orig.)

Relations in the family of patients with infiltrative pulmonary tuberculosis and recommendations for therapeutic interaction

Directory of Open Access Journals (Sweden)

Full Text Available A family is a social group that satisfies the most important needs and fulfils diverse functions. Patients with infiltrative pulmonary tuberculosis are not emotionally supported by their family members and hence experience anger and exasperation. The functioning of 30 families of patients with infiltrative pulmonary tuberculosis was psychologically studied using the family environment scale. The findings were compared with those of 100 standard families. Six out of 10 items showed significant differences, the other 4 items also displayed dissimilarities, but the latter were insignificant. The families of patients with pulmonary tuberculosis were dysfunctional. The social climate of the family had established well before infiltrative tuberculosis was diagnosed in its member. The dissimilarities from the standard families are due to the social characteristics of family members, such as low income, alcohol abuse, and imprisonment. The specific features of the social climate of a family provide an explanation for no moral support to the patient.

Human Immunodeficiency Virus (HIV) / Acquired Immune Deficiency Syndrome (AIDS) is a retrovirus that infects the human immune system. Damaged immunity in HIV/AIDS patients is marked by a decline in CD4 cells. Opportunistic infections appear differently, depending on the levels of immunosuppressive degrees, and the frequency of opportunistic infections in the environment. This study aims to describe the CD4 at various clinical stages of HIV/AIDS with tuberculosis and non-tuberculosis opportunistic infections (OI). Descriptive study with a cross-sectional design. This study is secondary data obtained from the medical records of patients with HIV/AIDS in the period of January 2011 - December 2015 at dr. Zainoel Abidin Hospital in Banda Aceh. The samples that met the inclusion criteria were 135 people with 63 cases were tuberculosis OI, 33 cases were non-tuberculosis and 39 cases were without OI. The study showed CD4 tuberculosis OI and 93.9% for non-tuberculosis OI.

Objective: To find out the time taken to, for diagnosis of tuberculosis and to put patient on DOTS from the onset of symptoms and pattern of health seeking behavior of new pulmonary tuberculosis patients. A cross-sectional rapid assessment using qualitative (FGD and quantitative (Interview methods conducted at DOTS center of tertiary care hospital from rural Wardha. Participants: 53 pulmonary tuberculosis patients already on DOTS, in intensive phase. Main outcome measure: Delay in initiation of DOTS & health seeking behavior Results: Median total delay for starting DOTS was 111 days, (range: 10 to 321 days. Patient delay was more than provider delay. Patients delay was more in patients above 60 years, illiterate, per-capita income below 650 Rupees and HIV TB co-infection. Pattern of health seeking behavior was complex. Family physician was the preferred health care provider. Patient visited on an average four providers and spent around 1450 rupees (only direct cost before DOTS begin. Time taken from the onset of symptoms and start of DOT is a cause of concern for the tuberculosis control program. Early case detection is important rather than mere achieving target of 70% new case detection. Program manager needs to implement locally relevant & focused strategies for early case detection to improve the treatment success, especially in rural area of India.

To determine the differences in the radiography findings of miliary tuberculosis between patients with and without associated acute respiratory failure (ARF). We retrospectively 32 patients in whom miliary tuberculosis had been diagnosed, and assigned them to one of two groups: with ARF (n=10), and without ARF (n=22). Chest radiographic findings such as presence of miliary modules, consolidation, ground-glass opacity (GGO), pleural effusion, small calcified nodules and linear opacities were assessed, the size and profusion of nodules in each of four zones were analyzed and scored using the standard radiographs of the international labor organization, and the extent of consolidation and GGO were scored according to the percentage on involved lung. We compared the radiologic findings between the two groups. Ground-glass opacity, consolidation, and pleural effusion were seen more frequently in miliary tuberculosis patinets with ARF than in those without ARF. Although the size and profusion of nodules were similar in both groups (p>0.05), consolidation and ground-glass opacity in cases of miliary tuberculosis with ARF were significantly more extensive than in those without ARF (p<0.005). GGO and consolidation were more extensive in miliary tuberculosis patients with ARF. A finding of ground-glass opacity in miliary tuberculosis patients might be an early indication of developing ARF

Based on analysis of data collected from the national tuberculosis prevention program in Djibouti between 1990 and 1996, the authors analyzed the relationship between HIV infection and tuberculosis. The study cohort comprised a total of 22,000 patients including 14,000 with documented HIV infection. Although HIV infection probably worsened the situation, it was neither the only nor the main factor involved in the resurgence of tuberculosis. Demographic growth, higher population density, and increasing poverty as well as the quality of the national tuberculosis prevention program must be taken into account. The incidence of smear-negative tuberculosis was not significantly higher in HIV-infected patients (incidence of smear positive cases, > 92%). Extrapulmonary tuberculosis especially of pleural involvement was more common (15% versus 9.4%). Treatment was effective in HIV-infected patients. If directly observed (DOT) therapy was used, there was no risk of emergence of multidrug-resistant tuberculosis strains. Drug side-effects associated with the protocols used in Djibouti were not greater in HIV-infected patients. Most additional mortality observed in HIV-infected tuberculosis patients (10.5% versus 2%) was due to progression of HIV infection.

Background: Tuberculosis is one of the highest mortality caused in a tropical country with abundant sunlight such Indonesia. Vitamin D and calcium plays important roles in tuberculosis pathogenesis. Objective:We sought to determine whether there is an association between vitamin D status and calcium status in tuberculosis patients. Design: We conducted a cross-sectional study of 32 man and women aged 18-60 years with active tuberculosis in North Sumatera, Indonesia. Parameters were 25(OH)D and calcium serum level, body mass index, fat mass, and others lifestyles factors also assessed. The association was analysis using chi-square or fischer test. Results: the mean of study subjects age were 37.2±14.9 years old and BMI were 20.8±4.4 kg/m2 There were 81.2% subjects categorized into vitamin D deficiency-insufficiency and 18.8% categorized into vitamin D sufficiency. There were 29% subjects categorized into normal calcium level, and 3% were hypocalcemia. Based on food recall analysis, there were found lower vitamin D and calcium intake. There is no association between vitamin D and calcium classification. Conclusions: based on this result, although there is no association between vitamin D and calcium, but there could be altered by lower food intake and tuberculosis progression.

We herein report a case of Addison's disease caused by tuberculosis characterized by atypical hyperpigmentation, noted as exacerbation of the pigmentation of freckles and the occurrence of new freckles, that was diagnosed in the presence of active pulmonary tuberculosis. The clinical condition of the patient was markedly ameliorated by the administration of hydrocortisone and anti-tuberculosis agents. When exacerbation of the pigmentation of the freckles and/or the occurrence of new freckles are noted, Addison's disease should be considered as part of the differential diagnosis. In addition, the presence of active tuberculosis needs to be assumed whenever we treat patients with Addison's disease caused by tuberculosis, despite its rarity.

[Tuberculosis in compromised hosts].

Science.gov (United States)

2003-11-01

Recent development of tuberculosis in Japan tends to converge on a specific high risk group. The proportion of tuberculosis developing particularly from the compromised hosts in the high risk group is especially high. At this symposium, therefore, we took up diabetes mellitus, gastrectomy, dialysis, AIDS and the elderly for discussion. Many new findings and useful reports for practical medical treatment are submitted; why these compromised hosts are predisposed to tuberculosis, tuberculosis diagnostic and remedial notes of those compromised hosts etc. It is an important question for the future to study how to prevent tuberculosis from these compromised hosts. 1. Tuberculosis in diabetes mellitus: aggravation and its immunological mechanism: Kazuyoshi KAWAKAMI (Department of Internal Medicine, Division of Infectious Diseases, Graduate School and Faculty of Medicine, University of the Ryukyus). It has been well documented that diabetes mellitus (DM) is a major aggravating factor in tuberculosis. The onset of this disease is more frequent in DM patients than in individuals with any underlying diseases. However, the precise mechanism of this finding remains to be fully understood. Earlier studies reported that the migration, phagocytosis and bactericidal activity of neutrophils are all impaired in DM patients, which is related to their reduced host defense to infection with extracellular bacteria, such as S. aureus and E. colli. Host defense to mycobacterial infection is largely mediated by cellular immunity, and Th1-related cytokines, such as IFN-gamma and IL-12, play a central role in this response. It is reported that serum level of these cytokines and their production by peripheral blood mononuclear cells (PBMC) are reduced in tuberculosis patients with DM, and this is supposed to be involved in the high incidence of tuberculosis in DM. Our study observed similar findings and furthermore indicated that IFN-gamma and IL-12 production by BCG-stimulated PBMC was lower

The material consumptive: domesticating the tuberculosis patient in Edwardian England

Science.gov (United States)

Mooney, Graham

2013-01-01

The proliferation of general and specialist hospitals, lunatic asylums, and workhouse infirmaries in the nineteenth century challenged the popular perception of the home as a suitable site of health care. Amidst the emergence of yet another type of institution, the tuberculosis sanatorium, tuberculosis control in the Edwardian period was re-sited and re-scaled to accommodate what might be termed a ‘preventive therapy’ of domestic space. Three interlinked perspectives demonstrate why and how this happened. First, I explore the role of the national and local state in legitimating domestic space as a scale and a site for the regulation of tuberculosis patients and prevention of the disease. Second, I investigate how tuberculosis self-help manuals promoted a technology of the self that was founded largely on the principles of sanatorium therapy but was necessarily reconfigured to reflect the social relations of domestic space. Third, I assess the marketing of consumer goods to the domiciled tuberculosis sufferer through the pages of the British Journal of Tuberculosis. It is suggested that a common tubercular ‘language’ of material consumption was fashioned in order to normalise the accumulation of possessions for use in the home. These arguments are situated in relation to recent historical research on material culture and identity at the turn of the twentieth century, which has stressed the cultivation of individuality and that the right sort of possessions appropriately arranged in domestic space signified well-regulated morality.

Drug therapy in spinal tuberculosis.

Rajasekaran, S; Khandelwal, Gaurav

2013-06-01

Although the discovery of effective anti-tuberculosis drugs has made uncomplicated spinal tuberculosis a medical disease, the advent of multi-drug-resistant Mycobacterium tuberculosis and the co-infection of HIV with tuberculosis have led to a resurgence of the disease recently. The principles of drug treatment of spinal tuberculosis are derived from our experience in treating pulmonary tuberculosis. Spinal tuberculosis is classified to be a severe form of extrapulmonary tuberculosis and hence is included in Category I of the WHO classification. The tuberculosis bacilli isolated from patients are of four different types with different growth kinetics and metabolic characteristics. Hence multiple drugs, which act on the different groups of the mycobacteria, are included in each anti-tuberculosis drug regimen. Prolonged and uninterrupted chemotherapy (which may be 'short course' and 'intermittent' but preferably 'directly observed') is effective in controlling the infection. Spinal Multi-drug-resistant TB and spinal TB in HIV-positive patients present unique problems in management and have much poorer prognosis. Failure of chemotherapy and emergence of drug resistance are frequent due to the failure of compliance hence all efforts must be made to improve patient compliance to the prescribed drug regimen.

1995-01-01

The purpose of our study is to evaluate the plain radiographic features of pulmonary tuberculosis in adult diabetic patients compared with those in patients without any underlying diseases. We analyzed the chest PA and lateral views of 100 patients having active pulmonary tuberculosis; 14 patients had diabetes mellitus and 60 patients had no other underlying diseases. Their images were assesed for anatomical distributions, extents of lesions, size and number of cavity and patterns of radiographic findings. Diabetic tuberculosis had higher prevalence and wider involvement of unusual segments for the tuberculosis such as anterior segment, lingular segment of upper lobe and basal segment of the lower lobe, and they showed the tendency of having more cavities than those who had no other underlying diseases, but there were no meaningful differences in the cavity size between the two groups. Pulmonary tuberculosis in diabetic patients tends to have wider extent with unusual segmental involvement and multiple cavities than in the patients who had no other underlying diseases

Most cases of adult-onset tuberculosis (TB) result from reactivation of a pre-existing Mycobacterium tuberculosis infection. Mycobacterium tuberculosis usually invades the respiratory tract and most patients develop intrapulmonary TB; however, some patients develop concurrent pulmonary and extra-pulmonary TB. The purpose of the present study was to identify the demographic and clinical factors associated with an increased risk of concurrent extra-pulmonary diseases in patients with pulmonary TB. We compared patients who had isolated pulmonary TB with patients who had concurrent pulmonary and extra-pulmonary TB. We initially analyzed one-million randomly selected subjects from the population-based Taiwan National Health Insurance database. Based on analysis of 5414 pulmonary TB patients in this database, women were more likely than men to have concurrent extra-pulmonary TB (OR: 1.30, p = 0.013). A separate analysis of the Kaohsiung Medical University Hospital database, which relied on sputum culture-proven pulmonary TB, indicated that women were more likely than men to have concurrent extra-pulmonary TB (OR: 1.62, p = 0.039). There was no significant gender difference in extra-pulmonary TB for patients younger than 45 years in either database. However, for patients 45 years and older, women were more likely than men to have concurrent extra-pulmonary TB (insurance database: 9.0% vs. 6.8%, p = 0.016, OR: 1.36; hospital database: 27.3% vs. 16.0%, p = 0.008, OR = 1.98). Our results indicate that among patients who have pulmonary TB, older females have an increased risk for concurrent extra-pulmonary TB.

We evaluated the adrenals of individuals without tuberculosis (group 1 - G1) and with tuberculosis (group 2 - G2) using computed tomography. The antero-posterior length, the thickness, and the longitudinal length of the adrenals were compared in G1 and G2. The duration of the disease, the occurrence of morphologic abnormalities in G2, the distribution according to sex, age and skin color were also studied. There was difference in the antero-posterior length and thickness of right adrenal between G1 and G2. A higher prevalence of white skin male individuals was observed in G2. There was no association between duration of the disease and the occurrence of morphologic abnormalities in G2. A higher occurrence of adrenal enlargement was observed in G2. The main computed tomography findings in patients with tuberculosis were enlargement of the adrenal without calcification, enlargement of the adrenal with punctiform calcifications, and residual calcification of the adrenal.

Tuberculosis (TB) is a serious public health concern, and Taiwan has implemented a pay-for-performance (P4P) program to incentivize healthcare professionals to provide comprehensive care to TB patients. This study aims to examine the effects of the TB P4P program on treatment outcomes and related expenses. A population-based natural experimental design with intervention and comparison groups. Propensity score matching was conducted to increase the comparability between the P4P and non-P4P group. A total of 12,018 subjects were included in the analysis, with 6009 cases in each group. Generalized linear models and multinomial logistic regression were employed to examine the effects of the P4P program. The regression models indicated that patients enrolled in the P4P program had 14% more ambulatory visits than non-P4P patients (P ratio, 1.56; P financial incentives to healthcare institutions could be a feasible model for better TB control.

Our objective was to evaluate the incidence of colorectal tuberculosis in our series and to study its radiological spectrum. A total of 684 cases of proven gastrointestinal tuberculosis with positive barium contrast findings seen over a period of more than one decade were evaluated. The study did not include cases where colon was involved in direct contiguity with ileo-caecal tuberculosis. Seventy-four patients (10.8%) had colorectal tuberculosis. Commonest site involved was transverse colon, closely followed by rectum and ascending colon. Radiological findings observed were in the form of strictures (54%), colitis (39%) and polypoid lesions (7%). Complications noted were in the form of perforations and fistulae in 18.9% of cases. Colorectal tuberculosis is a very common site for gastrointestinal tuberculosis. Typical findings of colorectal tuberculosis are strictures, signs of colitis and polypoid lesions. Common complications are perforation and fistulae. (orig.)

Full Text Available Drug resistance is one of the major concerns regarding tuberculosis (TB infection worldwide because it hampers control of the disease. Understanding the underlying mechanisms responsible for drug resistance development is of the highest importance. To investigate clinical data from drug-resistant TB patients at the Tropical Diseases Hospital, Goiás (GO, Brazil and to evaluate the molecular basis of rifampin (R and isoniazid (H resistance in Mycobacterium tuberculosis. Drug susceptibility testing was performed on 124 isolates from 100 patients and 24 isolates displayed resistance to R and/or H. Molecular analysis of drug resistance was performed by partial sequencing of the rpoB and katGgenes and analysis of the inhA promoter region. Similarity analysis of isolates was performed by 15 loci mycobacterial interspersed repetitive unit-variable number tandem repeat (MIRU-VNTR typing. The molecular basis of drug resistance among the 24 isolates from 16 patients was confirmed in 18 isolates. Different susceptibility profiles among the isolates from the same individual were observed in five patients; using MIRU-VNTR, we have shown that those isolates were not genetically identical, with differences in one to three loci within the 15 analysed loci. Drug-resistant TB in GO is caused by M. tuberculosis strains with mutations in previously described sites of known genes and some patients harbour a mixed phenotype infection as a consequence of a single infective event; however, further and broader investigations are needed to support our findings.

Full Text Available A review of literature about the study of lipid and protein peroxidation in children and teenagers with pulmonary tuberculosis nowadays was carried out. It was established that there is a great number works dedicated to the lipid peroxidation and antioxidant protective system in various pathological conditions of the respiratory system, including pulmonary tuberculosis in children and teenagers today. Oxidative modification proteins products are the earliest markers of oxidative stress in patients. There is no information on the oxidative modification of proteins in children and teenagers suffering from pulmonary tuberculosis in the literature. The study of oxidative modification of proteins will facilitate the development of more efficient new diagnosis methods and pathogenetic treatment of children and teenagers with pulmonary tuberculosis, that will increase the treatment effectiveness.

To determine the prevalence of diabetes mellitus among pulmonary tuberculosis patients and the difference of clinical characteristics and outcomes between pulmonary tuberculosis patients with and without diabetes mellitus in an aging population in Shanghai, China. This is a retrospective population-based study. 201 newly diagnosed pulmonary tuberculosis patients in Changning District, Shanghai during 2007-2008 were included. Clinical characteristics and outcomes were collected. Determination of diabetes mellitus was based on the medical records before pulmonary tuberculosis was diagnosed. The prevalence of diabetes mellitus among pulmonary tuberculosis patients was 19.9% (40/201). Pulmonary tuberculosis patients with diabetes mellitus were more likely to be old (≥50, OR=5.23, 95% CI=2.07-13.25), to have pulmonary cavities (OR=3.02, 95% CI=1.31-6.98), to be sputum smear positive (OR=2.90, 95% CI=1.12-7.51), and to have extension of anti-tuberculosis treatment duration (OR=2.68, 95% CI 1.17-6.14). Besides, they had a higher 2nd month sputum smear positive proportion (OR=2.97, 95% CI 1.22-7.22) and a higher 5-year recurrence rate (OR=5.87, 95% CI 1.26-27.40). High prevalence, severe clinical characteristics and poor outcomes of pulmonary tuberculosis patients with diabetes mellitus highlight the necessity of early bi-directional screening and co-management of these two diseases in Shanghai, China.

Full Text Available BACKGROUND: Leucocyte activating chemokines such as CCL2, CCL3, and CXCL8 together with proinflammatory IFNgamma, TNFalpha and downmodulatory IL10 play a central role in the restriction of M. tuberculosis infections, but is unclear whether these markers are indicative of tuberculosis disease severity. METHODOLOGY: We investigated live M. tuberculosis- and M. bovis BCG-induced peripheral blood mononuclear cell responses in patients with tuberculosis (TB and healthy endemic controls (ECs, n = 36. TB patients comprised pulmonary (PTB, n = 34 and extrapulmonary groups, subdivided into those with less severe localized extrapulmonary TB (L-ETB, n = 16 or severe disseminated ETB (D-ETB, n = 16. Secretion of CCL2, IFNgamma, IL10 and CCL3, and mRNA expression of CCL2, TNFalpha, CCL3 and CXCL8 were determined. RESULTS: M. tuberculosis- and BCG-induced CCL2 secretion was significantly increased in both PTB and D-ETB (p<0.05, p<0.01 as compared with L-ETB patients. CCL2 secretion in response to M. tuberculosis was significantly greater than to BCG in the PTB and D-ETB groups. M. tuberculosis-induced CCL2 mRNA transcription was greater in PTB than L-ETB (p = 0.023, while CCL2 was reduced in L-ETB as compared with D-ETB (p = 0.005 patients. M. tuberculosis-induced IFNgamma was greater in L-ETB than PTB (p = 0.04, while BCG-induced IFNgamma was greater in L-ETB as compared with D-ETB patients (p = 0.036. TNFalpha mRNA expression was raised in PTB as compared with L-ETB group in response to M. tuberculosis (p = 0.02 and BCG (p = 0.03. Mycobacterium-induced CCL3 and CXCL8 was comparable between TB groups. CONCLUSIONS: The increased CCL2 and TNFalpha in PTB patients may support effective leucocyte recruitment and M. tuberculosis localization. CCL2 alone is associated with severity of TB, possibly due to increased systemic inflammation found in severe disseminated TB or due to increased monocyte infiltration to lung parenchyma in pulmonary disease.

Full Text Available Role of microRNA (miRNA has been highlighted in pathogen-host interactions recently. At present, their role in active pulmonary tuberculosis is unknown. The aim of the study was to delineate miRNA expression in sputum supernatant of patients with active pulmonary tuberculosis. Expression of miRNAs was evaluated by microarray analysis and differentially expressed miRNAs were validated by RT-qPCR. Secreted cytokines TNF-α and IL-6 were measured by ELISA. We found that 95 miRNAs were differentially expressed between tuberculosis group and controls. More miRNAs (52 out of 95 miRNAs were underexpressed than overexpressed during tuberculosis infection. Overexpression of miR-3179, miR-147 and underexpression of miR-19b-2* in TB group compared with controls were confirmed in the validation cohort. TNF-α and IL-6 levels were not significantly altered between TB group and controls. For the first time, differential expression of miRNAs in sputum was found in active pulmonary tuberculosis. The study provides rationale for identifying the role of miRNAs in the pathogenesis of pulmonary tuberculosis and indicates potential for miRNA-based therapeutic strategies.

Under India's Revised National Tuberculosis Control Programme (RNTCP), >15% of previously-treated patients in the reported 2006 patient cohort defaulted from anti-tuberculosis treatment. To assess the timing, characteristics, and risk factors for default amongst re-treatment TB patients. For this case-control study, in 90 randomly-selected programme units treatment records were abstracted from all 2006 defaulters from the RNTCP re-treatment regimen (cases), with one consecutively-selected non-defaulter per case. Patients who interrupted anti-tuberculosis treatment for >2 months were classified as defaulters. 1,141 defaulters and 1,189 non-defaulters were included. The median duration of treatment prior to default was 81 days (25%-75% interquartile range 44-117 days) and documented retrieval efforts after treatment interruption were inadequate. Defaulters were more likely to have been male (adjusted odds ratio [aOR] 1.4, 95% confidence interval [CI] 1.2-1.7), have previously defaulted anti-tuberculosis treatment (aOR 1.3 95%CI 1.1-1.6], have previous treatment from non-RNTCP providers (AOR 1.3, 95%CI 1.0-1.6], or have public health facility-based treatment observation (aOR 1.3, 95%CI 1.1-1.6). Amongst the large number of re-treatment patients in India, default occurs early and often. Improved pre-treatment counseling and community-based treatment provision may reduce default rates. Efforts to retrieve treatment interrupters prior to default require strengthening.

This study examined 40 patients: 34 have pulmonary tuberculosis, 3 have pneumonitis, 2 have lung cancer, and one has bilharziasis. All patients have been imaged using radioisotopes compounds (99mTc-infecton and 99mTcHIG) and after 1 hour and 4 hours of patients injection.Using 99mTc-infecton gave positive results in 30 pulmonary tuberculosis patients out of 34, the 3 pneumonitis patients, while using 99mTcHIG gave positive results in 27 pulmonary tuberculosis patients including the 3 pneumonitis patients. Both 99mTc-infecton and 99mTcHIG gave negative results with the lung cancer patients and unreal positive results with the bilharziasis patient. It has been found that the sensitivity and accuracy in the examinations using 99mTc-infecton were 88%, 93%, and 85.7% respectively in comparison with using 99mTcHIG where the values were 70.6%, 91%, and 68.5% respectively. Continuing examination and monitoring of 18 tuberculosis patients for 2-18 months with anti-pulmonary tuberculosis treatment, showed complete response of 12 patients using 99mTc-infecton, and 8 by using 99mTcHIG. As a result, 99mTc-infecton can be used for examining pulmonary tuberculosis patients

We report on three cases of longstanding pulmonary tuberculosis patients with coronary to bronchial artery fistula (CBF) who presented with recurrent massive hemoptysis. The first and second patients died because of decreased functional pulmonary volume plus massive hemoptysis and cannulation failure of CBF due to hypovolemic vasospasm, respectively. When recurrent hemoptysis occurs despite successful embolization treatment, CBF should be considered as a potential bleeding source. Moreover, a coronary angiography should be performed, especially in patients with longstanding cardiopulmonary disease such as pulmonary tuberculosis.

Frequency of resistance-conferring mutations vary among isoniazid- and ethambutol-resistant Mycobacterium tuberculosis isolates obtained from patients of various ethnic groups. This study was aimed to determine the occurrence of specific rpoB mutations in rifampicin-resistant M. tuberculosis isolates from tuberculosis patients of various ethnic groups in Kuwait. Rifampicin-resistant M. tuberculosis isolates (n=119) from South Asian (n=55), Southeast Asian (n=23), Middle Eastern (n=39) and other (n=2) patients and 107 rifampicin-susceptible isolates were tested. Mutations in rpoB were detected by DNA sequencing. Polymorphisms at katG463 and gyrA95 were detected by PCR-RFLP for genetic group assignment. None of rifampicin-susceptible but 116 of 119 rifampicin-resistant isolates showed rpoB mutation(s). Mutations among isolates from South Asian patients were distributed at rpoB516 (20%), rpoB526 (24%) and rpoB531 (27%) while 78 and 51 per cent of isolates from Southeast Asian and Middle Eastern patients, respectively, contained a mutated rpoB531. All isolates with rpoB N-terminal and cluster II mutations were obtained from Middle Eastern and South Asian patients. Most isolates from South Asian (84%) and Southeast Asian (70%) patients belonged to genetic group I while nearly all remaining isolates belonged to genetic group II. Isolates from Middle Eastern patients were distributed among genetic group I (46%), genetic group II (33%) and genetic group III (21%). The occurrence of specific rpoB mutations varied considerably in rifampicin-resistant M. tuberculosis isolates obtained from patients of different ethnic groups within the same country. The present data have important implications for designing region-specific rapid methods for detecting majority of rifampicin-resistant strains.

The x-ray signs of connective tissue systemic dysplasia (CTSD) in patients with primarily diagnosed pulmonary tuberculosis was investigated. Fifty-four patients (28 med and 26 women aged 18-70) with primarily diagnosed infiltrative pulmonary tuberculosis underwent x-ray study. In patients with infiltration pulmonary tuberculosis CTSD in the lungs manifests by their diminishing, deformity of the lung pattern, high position of the diaphragm cupola, mediastinum shift to the side of the pathology, which is better seen on CT. The degree of CTSD x-ray signs in the lungs depends on the number of phenotypical signs that is the degree of the disease manifestation. CT allows more accurate determining of the signs of connective tissue dysplasia in which tuberculosis develops

This study identified urinary biomarkers for tuberculosis (TB) diagnosis. The urine proteomic profiles of 45 pulmonary tuberculosis patients prior to anti-TB treatment and 45 healthy controls were analyzed and compared using two-dimensional electrophoresis with matrix-assisted laser desorption/ionization time of flight mass spectrometry. Nineteen differentially expressed proteins were identified preliminarily, and western blotting and qRT-PCR were performed to confirm these changes at the translational and transcriptional levels, respectively, using samples from 122 additional pulmonary tuberculosis patients and 73 additional healthy controls. Two proteins, mannose-binding lectin 2 and a 35-kDa fragment of inter-α-trypsin inhibitor H4, exhibited the highest differential expression. We constructed a protein-microRNA interaction network that primarily involved complement and inflammatory responses. Eleven microRNAs from microRNA-target protein interactions were screened and validated using qRT-PCR with some of the above samples, including 97 pulmonary tuberculosis patients and 48 healthy controls. Only miR-625-3p exhibited significant differential expression (p tuberculosis diagnosis than individual biomarkers or any two-biomarker combination and generated a diagnostic sensitivity of 85.87% and a specificity of 87.50%. These novel urine biomarkers may significantly improve tuberculosis diagnosis.

Tuberculosis (TB) is a major cause of death worldwide. Finding an effective vaccine against TB is the best way to control it. Several vaccines against this disease have been developed but none are completely protective. The aim of this study was to design and construct a cloning vector containing the Mycobacterium tuberculosis (M. tuberculosis) heat shock protein X (hspX) . First, an hspX fragment was amplified by PCR and cloned into plasmid pcDNA3.1(+) and recombinant vector was confirmed. A 435 bp hspX fragment was isolated. The fragment was 100% homologous with hspX of M. tuberculosis strain H37Rv in GenBank. In this study, the cloning vector pcDNA3.1(+), containing a 435-bp hspX fragment of M. tuberculosis , was constructed. This could be used as a DNA vaccine to induce immune responses in animal models in future studies.

Tuberculosis is a systemic disease that still affects many people. While pleural involvement is frequently observed in extrapulmonary tuberculosis, multiple skeletal system and articular involvements are quite rare. FDG PET imaging could be a promising diagnostic and treatment monitoring method, especially in complicated cases and if the other methods are inadequate. In this case study, we report a patient who was admitted with suspected malignancy and then diagnosed with tuberculosis pleuritis, lymphadenitis, spondylodiscitis, and sacroiliitis with specific symptoms; the response to anti-tuberculosis therapy was shown using FDG PET/CT

Pulmonary tuberculosis relapse is defined as these patients that make recurrence of tuberculosis after complete an adequate treatment, and these patients are again diagnosed bacteriologically with tuberculosis. We tried to identify the risk factors for relapse among adults, through an analytical study of cases and controls, with eighty patients among the tuberculosis programmed of Santa Clara Hospital between 1992-2000 with relapse diagnosis which meet criterion of case and eighty patients which meet criterion of control. We did a bivariate analysis with confidence intervals and univariate calculation with logistic regression analysis to predict the development of relapse for the different variables. Diabetes mellitus, chronic renal failure, silicosis are associated with relapse, but in our study we found another factors which are joined to relapse and we suggest that if we find these factors among tuberculosis patients would indicate the chance of relapse and this would create the necessity of use a larger number of doses of antituberculosis medicaments

Surgical face masks used by patients with tuberculosis (TB) are believed to reduce transmission but have not been rigorously tested. Objectives: We sought to quantify the efficacy of surgical face masks when worn by patients with multidrug-resistant TB (MDR-TB). Methods: Over 3 months, 17 patients with pulmonary MDR-TB occupied an MDR-TB ward in South Africa and wore face masks on alternate days. Ward air was exhausted to two identical chambers, each housing 90 pathogen-free guinea pigs that breathed ward air either when patients wore surgical face masks (intervention group) or when patients did not wear masks (control group). Efficacy was based on differences in guinea pig infections in each chamber. Measurements and Main Results: Sixty-nine of 90 control guinea pigs (76.6%; 95% confidence interval [CI], 68–85%) became infected, compared with 36 of 90 intervention guinea pigs (40%; 95% CI, 31–51%), representing a 56% (95% CI, 33–70.5%) decreased risk of TB transmission when patients used masks. Conclusions: Surgical face masks on patients with MDR-TB significantly reduced transmission and offer an adjunct measure for reducing TB transmission from infectious patients. PMID:22323300

Tuberculosis (TB) is a worldwide public health problem. It is a contagious and grave disease caused by Mycobacterium tuberculosis. Current drugs such as isoniazid, pyrazinamide, and rifampicin used for the treatment of tuberculosis are potentially hepatotoxic and can lead to drug hepatitis. In order to improve the follow-up of TB patients in Cameroon, we carried out a study which aimed to evaluate the hepatotoxicity risk factors associated with anti-TB drugs. The studies were performed on 75 participants who had visited the Loum District Hospital located in the littoral region of Cameroon for their routine consultation. Participants have been selected based on pre-established criteria of inclusion and exclusion. Prior to the informed consent signature, patients were given compelling information about the objective and the result output of the study. They were questioned about antioxidant food and alcohol consumption as well as some clinical signs of hepatotoxicity such as fever, nausea, vomiting, and tiredness. The collected blood was tested for the determination of biochemical markers (transaminases and C-reactive protein) using standard spectrophotometric methods. Biochemical analysis of samples showed a significant increase (pfactors, antioxidant food consumption significantly reduced the liver injury patient percentage for the above parameters, whereas an opposite situation was observed with alcohol consumption between TB-coinfection and TB patients. Regarding the C-reactive protein results, the percentage of positive tests was very high among coinfected patients (40%) compared with the control (15%). The interactions between parameters related to alcohol consumption and intake of antioxidant foods showed a slight decrease in activity compared with interactions without food. The results showed that human immunodeficiency virus status and alcohol consumption constitutes aggravating factors for the occurrence of hepatic toxicity. In addition, the consumption of

To present our experience with abdominal tuberculosis in children and adolescents treated in our hospital from 2003 - 2014. It is a retrospective study. We have collected clinical records of inpatients overweight or obese and only 23.33% suffered of malnutrition. TB contact was present in 10 (33.33%). Positive tuberculin skin tests were seen in 10%. Extra-abdominal tuberculosis was found in 22 patients (63.32%). 12 cases had coexisting pulmonary tuberculosis and 4 cases had pleural effusion. 12 patients (40%) had tuberculous peritonitis; 12 patients (40%) had intestinal tuberculosis and peritoneal tuberculosis and 4 patients (13.33%) had intestinal tuberculosis. Bacteriological confirmation of tuberculosis was achieved in 10 cases (33.33%). Antituberculous therapy for 6 months was effective in 29 cases. One patient died who multifocal tuberculosis with HIV had associated. Abdominal tuberculosis is seen in 4.37% of children affected with tuberculosis, of which over 63% will have extra abdominal manifestations. Abdominal tuberculosis should be considered in patients with abdominal pain, fever, weight loss and abnormal chest radiography. Imaging can be useful for early diagnosis of abdominal tuberculosis.

Mycobacterium tuberculosis infection constitutes a global threat that results in significant morbidity and mortality worldwide. Efficient and early diagnosis of tuberculosis (TB) is of paramount importance for successful treatment. The aim of the current study is to investigate the mycobacterial mycothiol acetyltransferase Rv0819 as a potential novel biomarker for the diagnosis of active TB infection. The gene encoding Rv0819 was cloned and successfully expressed in Escherichia coli. The recombinant Rv0819 was purified using metal affinity chromatography and was used to raise murine polyclonal antibodies against Rv0819. The raised antibodies were employed for direct detection of Rv0819 in patient serum samples using dot blot assay and competitive enzyme-linked immunosorbent assay (ELISA). Serum samples were obtained from 68 confirmed new TB patients and 35 healthy volunteers as negative controls. The dot blot assay showed sensitivity of 64·7% and specificity of 100%, whereas the competitive ELISA assay showed lower sensitivity (54·4%) and specificity (88·57%). The overall sensitivity of the combined results of the two tests was found to be 89·7%. Overall, the mycobacterial Rv0819 is a potential TB serum biomarker that can be exploited, in combination with other TB biomarkers, for efficient and reliable diagnosis of active TB infection. The early and accurate diagnosis of tuberculosis infection is of paramount importance for initiating treatment and avoiding clinical complications. Most current diagnostic tests have poor sensitivity and/or specificity and in many cases they are too expensive for routine diagnostic testing in resource-limited settings. In the current study, we examined a novel mycobacterial serum biomarker, namely mycothiol acetyltransferase Rv0819. The antigen was detectable in serum specimens of a significant number of tuberculosis patients. This article proves the importance of Rv0819 and paves the way towards its future use as a useful

Mycobacterium tuberculosis genotyping can effectively improve tuberculosis (TB) control programs by controlling disease transmission. Pulsed field gel electrophoresis (PFGE) is a particularly powerful tool for determination of clonal identity of bacteria providing information for understanding and controlling the spread of disease. The aim of present study was to investigate the genetic diversity of M. tuberculosis strains in Khuzestan province by the PFGE technique. In total, 80 M. tuberculosis positive cultures were obtained from tuberculosis patients. PFGE was performed on 60 PCR-confirmed isolates by using DraI and XbaI restriction enzymes according to standard protocols. Plugs containing digested DNA were then loaded on agarose gels and run using contour-clamped homogenous electric fields. Fifty distinct DNA banding patterns were obtained by digestion of DNA with DraI and 38 DNA banding patterns by digestion with XbaI restriction enzymes. The patterns comprised of 17 different clusters in which cluster I was the major one, containing six strains. Three clusters contained three strains each and the 13 remaining clusters comprised of two strains each. Digestion with DraI yielded 15-20 DNA fragments with 50-485 kb size, while digestion by XbaI produced DNA fragments with a size smaller than 50-242 kb. Despite the ability of PFGE for study of genetic diversity of many mycobacterial species and it being considered as a robust and useful tool, in this study we only found a 15% epidemiological relationship amongst the isolates. Thus, for higher discrimination of genotypic clusters among M. tuberculosis clinical isolates, the application of more sophisticated complementary techniques is required.

To evaluate the radiologic findings of breast tuberculosis. The authors evaluated the radiologic findings of five cases of surgically confirmed tuberculosis of the breast. Patients were examined with mammography (n=5), ultrasonography (n=3), and MRI (n=2). All patients were female. Four patients had unilateral lesion and the remaining one patient had bilateral breast tuberculosis. Mammographic findings were mainly radiopaque mass density without secondary signs. Two patients showed secondary signs such as skin thickening, parenchymal distortion, and nipple retraction. Ultrasonographic findings were variable but helpful in differentiating benign from malignant breast lesion, MRI findings were more helpful in differentiating abscess from malignant lesions. Radiologic findings were useful to diagnose tuberculosis of the breast, but fine needle aspiration biopsy and culture were needed for suspicious radiologic findings.

Full Text Available En la actualidad la incidencia de la tuberculosis ha aumentado. El Mycobacterium tuberculosis infecta frecuentemente a las personas con SIDA, debido a que en estos pacientes hay una reducción de la resistencia mediada por células T, lo que propicia que este bacilo pueda desarrollar la enfermedad con una frecuencia superior a la de las personas sanas. La transmisión de la enfermedad puede ser por vía directa, de un individuo afectado a otro, fundamentalmente por las gotitas de saliva que contengan a este microorganismo, o por vía indirecta por la inhalación del bacilo que se puede encontrar por meses en los objetos de uso diario, debido a su gran resistencia. Las micobacterias que producen tuberculosis en el hombre inmunocompetente son la Mycobacterium tuberculosis y la bovis, otros tipos pueden provocar tuberculosis en individuos inmunocomprometidos. La patogenicidad de este bacilo está relacionada con su capacidad para escapar de la destrucción inducida por los macrófagos y para provocar hipersensibilidad de tipo retardado. Esta enfermedad tiene muy pocas manifestaciones bucales, lo que se observa generalmente es una úlcera que toma como asiento fundamental el dorso de la lengua. La tuberculosis amenaza con convertirse en una enfermedad incurable por la deficiente administración de los programas contra ésta, por lo que la OMS plantea para su detección y tratamiento el DOTS (tratamiento observado directamente, de corta duración que comienza a tener resultados satisfactorios, aunque en el último quinquenio, el 88 % de los pacientes que se estimaban como infectados por tuberculosis no recibieron DOTS.At present, the incidence of tuberculosis is on the rise. Mycobacterium tuberculosis often infests AIDS patients due to the fact that these persons´T-cell mediated resistance is reduced, which favors the development of the disease at a higher rate than in healthy people.

Pulmonary tuberculosis is occasionally confused with invasive pulmonary aspergillosis (IPA) in transplant recipients, since clinical suspicion and early diagnosis of pulmonary tuberculosis and IPA rely heavily on imaging modes such as computed tomography (CT). We therefore investigated IPA-mimicking tuberculosis in transplant recipients. All adult transplant recipients who developed tuberculosis or IPA at a tertiary hospital in an intermediate tuberculosis-burden country during a 6-year period were enrolled. First, we tested whether experienced radiologists could differentiate pulmonary tuberculosis from IPA. Second, we determined which radiologic findings could help us differentiate them. During the study period, 28 transplant recipients developed pulmonary tuberculosis after transplantation, and 80 patients developed IPA after transplantation. Two experienced radiologists scored blindly 28 tuberculosis and 50 randomly selected IPA cases. The sensitivities of radiologists A and B for IPA were 78% and 68%, respectively (poor agreement, kappa value = 0.25). The sensitivities of radiologists A and B for tuberculosis were 64% and 61%, respectively (excellent agreement, kappa value = 0.77). We then compared the CT findings of the 28 patients with tuberculosis and 80 patients with IPA. Infarct-shaped consolidations and smooth bronchial wall thickening were more frequent in IPA, and mass-shaped consolidations and centrilobular nodules (tuberculosis. Certain CT findings appear to be helpful in differentiating between IPA and tuberculosis. Nevertheless, the CT findings of about one-third of pulmonary tuberculosis cases in transplant recipients are very close to those of IPA. © The Author 2015.

Mexico City, Mexico. To identify proteins synthetised by Mycobacterium tuberculosis in hypoxic culture, which resemble more closely a granuloma environment than aerobic culture, and to determine if they are recognised by antibodies from patients with active pulmonary tuberculosis (PTB). Soluble extracts from M. tuberculosis H37Rv cultured under aerobic or hypoxic conditions were analysed using two-dimensional polyacrylamide gel electrophoresis, and proteins over-expressed under hypoxia were identified by mass spectrometry. The presence of immunoglobulin (Ig) G, IgA and IgM antibodies against these proteins was determined in the serum of 42 patients with active PTB and 42 healthy controls. We selected three M. tuberculosis H37Rv proteins (alpha-crystallin protein [Acr, Rv2031c], universal stress protein Rv2623 and isocitrate lyase [ICL, RV0467]) that were over-expressed under hypoxia. Titres of anti-Acr and anti-ICL IgA antibodies were higher in patients than in healthy controls, with an area under the receiver operating characteristic curve of 0.71 for anti-ICL IgA antibodies. ICL could be used in combination with other M. tuberculosis antigens to improve the sensitivity and specificity of current serological TB diagnostic methods.

We report an atypical case of Rhodotorula mucilaginosa fungemia coexisting with pleural tuberculosis, in an immunocompetent host. The patient was an inhaled drug abuser and worked in a fruit market. The diagnosis of Rhodotorula mucilaginosa infection was established by the isolation of the yeast in two blood cultures followed by a good response to amphotericin B treatment. Persistent evening fever and pleural effusion led to the second diagnosis-pleural tuberculosis. In the last 5 years, this was the only case of Rhodotorula mucilaginosa fungemia in our hospital and the first case in the literature that documents Rhodotorula mucilaginosa fungemia associated with pleural tuberculosis.

Isoniazid mono-resistance (IMR) is the most common form of mono-resistance; its world prevalence is estimated to range between 0.0 to 9.5% globally. There is no consensus on how these patients should be treated. To describe the impact of IMR tuberculosis (TB) on treatment outcome and survival among pulmonary TB patients treated under programmatic conditions in Orizaba, Veracruz, Mexico. We conducted a prospective cohort study of pulmonary TB patients in Southern Mexico. From 1995 to 2010 patients with acid-fast bacilli or culture proven Mycobacterium tuberculosis in sputum samples underwent epidemiological, clinical and microbiological evaluation. We included patients who harbored isoniazid mono-resistant (IMR) strains and patients with strains susceptible to isoniazid, rifampicin, ethambutol and streptomycin. All patients were treated following Mexican TB Program guidelines. We performed annual follow-up to ascertain treatment outcome, recurrence, relapse and mortality. Between 1995 and 2010 1,243 patients with pulmonary TB were recruited; 902/1,243 (72.57%) had drug susceptibility testing; 716 (79.38%) harbored pan-susceptible and 88 (9.75%) IMR strains. Having any contact with a person with TB (adjusted odds ratio (aOR)) 1.85, 95% Confidence interval (CI) 1.15-2.96) and homelessness (adjusted odds ratio (aOR) 2.76, 95% CI 1.08-6.99) were associated with IMR. IMR patients had a higher probability of failure (adjusted hazard ratio (HR) 12.35, 95% CI 3.38-45.15) and death due to TB among HIV negative patients (aHR 3.30. 95% CI 1.00-10.84). All the models were adjusted for socio-demographic and clinical variables. The results from our study provide evidence that the standardized treatment schedule with first line drugs in new and previously treated cases with pulmonary TB and IMR produces a high frequency of treatment failure and death due to tuberculosis. We recommend re-evaluating the optimal schedule for patients harboring IMR. It is necessary to strengthen

A total of 52.4% of MDR TB patients had never been treated for TB, which suggests primary transmission of MDR M. tuberculosis. At initiation of treatment for MDR TB, 59.7% of M. tuberculosis strains tested were...

A New Method to Directly Observe Tuberculosis Treatment: Skype Observed Therapy, a Patient-Centered Approach.

Science.gov (United States)

Buchman, Tavora; Cabello, Celina

Tuberculosis (TB) treatment completion is in part determined by patient's adherence to long-term drug regimens. To best ensure compliance, directly observed therapy (DOT) is considered the standard of practice. Nassau County Department of Health TB Control is responsible for providing DOT to patients with TB. Tuberculosis Control sought to use and evaluate Skype Observed Therapy (SOT) as an alternative to DOT for eligible patients. The evaluation included analysis of patient's acceptance and adherence to drug regimen using SOT. Tuberculosis Control assessed staff efficiency and cost savings for this program. Percentages of SOT of patients and successful SOT visits, mileage, and travel time savings. Twenty percent of the caseload used SOT and 100% of patients who were eligible opted in. Average SOT success was 79%. Total mileage savings and time saved were $9,929.07 and 614 hours. Because SOT saves cost and time and is a suitable alternative to DOT for patients, it should be considered as part of new policies and practices in TB control programs.

Existing studies of the quality of tuberculosis care have relied on recall-based patient surveys, questionnaire surveys of knowledge, and prescription or medical record analysis, and the results mostly show the health-care provider's knowledge rather than actual practice. No study has used standardised patients to assess clinical practice. Therefore we aimed to assess quality of care for tuberculosis using such patients. We did a pilot, cross-sectional validation study of a convenience sample of consenting private health-care providers in low-income and middle-income areas of Delhi, India. We recruited standardised patients in apparently good health from the local community to present four cases (two of presumed tuberculosis and one each of confirmed tuberculosis and suspected multidrug-resistant tuberculosis) to a randomly allocated health-care provider. The key objective was to validate the standardised-patient method using three criteria: negligible risk and ability to avoid adverse events for providers and standardised patients, low detection rates of standardised patients by providers, and data accuracy across standardised patients and audio verification of standardised-patient recall. We also used medical vignettes to assess providers' knowledge of presumed tuberculosis. Correct case management was benchmarked using Standards for Tuberculosis Care in India (STCI). Between Feb 2, and March 28, 2014, we recruited and trained 17 standardised patients who had 250 interactions with 100 health-care providers, 29 of whom were qualified in allopathic medicine (ie, they had a Bachelor of Medicine & Surgery [MBBS] degree), 40 of whom practised alternative medicine, and 31 of whom were informal health-care providers with few or no qualifications. The interactions took place between April 1, and April 23, 2014. The proportion of detected standardised patients was low (11 [5%] detected out of 232 interactions among providers who completed the follow-up survey), and

New treatment guidelines are required to improve the tuberculosis control strategies that have been used for 30 years. Seven centers of the Barcelona Tuberculosis Research Unit (BTRU) (Unitat d'Investigació en Tuberculosi de Barcelona) are collaborating with the Division of Tuberculosis Elimination of the United States Centers for Disease Control and Prevention in a series of clinical trials on latent tuberculosis infection and tuberculosis disease. BTRU participation began in 2004 with Study 26, an evaluation of the efficacy and tolerability of rifapentine plus isoniazid administered once weekly for 3 months compared with the standard treatment for latent tuberculosis infection. The BTRU centers together enrolled 246 patients (3% of the total). General enrollment was completed in February, 2008. HIV-infected patient and child enrollment continues. Treatment with 12 doses instead of 270 doses is expected to be a clear success. However, the analysis will be completed in 2010. Study 28 (started in 2006), designed for the treatment of pulmonary tuberculosis, compared standard treatment with an experimental regimen substituting moxifloxacin for isoniazid. BTRU centers together enrolled 15 patients (3.5% of the total). The provisional results (presented at the 47th Interscience Conference on Antimicrobial Agents and Chemotherapy in Chicago, 2007) showed no difference between the sputum conversion rate of each regimen at week 8 of treatment. Study 29 is currently underway, in which rifapentine was introduced in the experimental regimen for active tuberculosis treatment. Copyright (c) 2009 SESPAS. Published by Elsevier Espana.

Tuberculosis (TB) patients face substantial delays prior to treatment initiation, and out of pocket (OOP) expenditures often surpass the economic productivity of the household. We evaluated the pre-diagnostic cost and health seeking behaviour of new adult pulmonary TB patients registered at Primary Health Centres (PHCs) in Vellore district, Tamil Nadu, India. This descriptive study, part of a randomised controlled trial conducted in three rural Tuberculosis Units from Dec 2012 to Dec 2015, collected data on number of health facilities, dates of visits prior to the initiation of anti-tuberculosis treatment, and direct OOP medical costs associated with TB diagnosis. Logistic regression analysis examined the factors associated with delays in treatment initiation and OOP expenditures. Of 880 TB patients interviewed, 34.7% presented to public health facilities and 65% patients sought private health facilities as their first point of care. The average monthly individual income was $77.79 (SD 57.14). About 69% incurred some pre-treatment costs at an average of $39.74. Overall, patients experienced a median of 6 days (3-11 IQR) of time to treatment initiation and 21 days (10-30 IQR) of health systems delay. Age ≤ 40 years (aOR: 1.73; CI: 1.22-2.44), diabetes (aOR: 1.63; CI: 1.08-2.44) and first visit to a private health facility (aOR: 17.2; CI: 11.1-26.4) were associated with higher direct OOP medical costs, while age ≤ 40 years (aOR: 0.64; CI: 0.48-0.85) and first visit to private health facility (aOR: 1.79, CI: 1.34-2.39) were associated with health systems delay. The majority of rural TB patients registering at PHCs visited private health facilities first and incurred substantial direct OOP medical costs and delays prior to diagnosis and anti-tuberculosis treatment initiation. This study highlights the need for PHCs to be made as the preferred choice for first point of contact, to combat TB more efficiently.

ABSTRACT Improved knowledge regarding the tissue penetration of antituberculosis drugs may help optimize drug management. Patients with drug-resistant pulmonary tuberculosis undergoing adjunctive surgery were enrolled. Serial serum samples were collected, and microdialysis was performed using ex vivo lung tissue to measure pyrazinamide concentrations. Among 10 patients, the median pyrazinamide dose was 24.7 mg/kg of body weight. Imaging revealed predominant lung lesions as cavitary (n = 6 patients), mass-like (n = 3 patients), or consolidative (n = 1 patient). On histopathology examination, all tissue samples had necrosis; eight had a pH of ≤5.5. Tissue samples from two patients were positive for Mycobacterium tuberculosis by culture (pH 5.5 and 7.2). All 10 patients had maximal serum pyrazinamide concentrations within the recommended range of 20 to 60 μg/ml. The median lung tissue free pyrazinamide concentration was 20.96 μg/ml. The median tissue-to-serum pyrazinamide concentration ratio was 0.77 (range, 0.54 to 0.93). There was a significant inverse correlation between tissue pyrazinamide concentrations and the amounts of necrosis (R = −0.66, P = 0.04) and acid-fast bacilli (R = −0.75, P = 0.01) identified by histopathology. We found good penetration of pyrazinamide into lung tissue among patients with pulmonary tuberculosis with a variety of radiological lesion types. Our tissue pH results revealed that most lesions had a pH conducive to pyrazinamide activity. The tissue penetration of pyrazinamide highlights its importance in both drug-susceptible and drug-resistant antituberculosis treatment regimens. PMID:28373198

Full Text Available The aim of this study was to assess the prevalence of hazardous and harmful alcohol use and associated factors among patients with tuberculosis in South Africa. In a cross-sectional survey new tuberculosis (TB and TB retreatment patients were consecutively screened using the Alcohol Use Disorder Identification Test (AUDIT within one month of anti-tuberculosis treatment. The sample included 4,900 (54.5% men and women 45.5% tuberculosis patients from 42 primary care clinics in three districts. Results indicate that, overall 23.2% of the patients were hazardous or harmful alcohol drinkers, 31.8% of men and 13.0% of women were found to be hazardous drinkers, and 9.3% of men and 3.4% of women meet criteria for probable alcohol dependence (harmful drinking as defined by the AUDIT. Men had significantly higher AUDIT scores than women. In multivariable analyses it was found that among men poor perceived health status, tobacco use, psychological distress, being a TB retreatment patient and not being on antiretroviral therapy (ART, and among women lower education, tobacco use and being a TB retreatment patient were associated with hazardous or harmful alcohol use. The study found a high prevalence of hazardous or harmful alcohol use among tuberculosis primary care patients. This calls for screening and brief intervention and a comprehensive alcohol treatment programme as a key component of TB management in South Africa.

A few reports and the authors’ experiences indicate that tuberculosis may result in a false-positive brucellosis serology. This may cause a diagnostic challenge because of the close clinical resemblance of these two infections.Objective: The aim of the present prevalence study was to elucidate brucellosis seroreactivity in patients with active TB.Methods: Ninety-eight patients with newly diagnosed and active TB were studied using an enzyme-linked immunosorbent assay (ELISA and Wright’s and Coombs–Wright’s tests. Seventy-five healthy individuals were used as controls. The patients showed signs of recovery after starting a standard anti-TB regimen and had no clinical evidence of brucellosis at a subsequent 6-month follow-up. The data were analyzed statistically by Fisher’s exact test using SPSS 11.0.Results: We found that 9.2% of TB patients versus 1.3% of healthy controls had positive results on the anti-Brucella IgG ELISA (P = 0.04. Five TB patients were found to have agglutination on Wright’s tests, while none of the controls showed agglutination.Conclusion: Active TB patients may have some seroreactivity with Brucella antigens, and Brucella IgG ELISA may give a false positive in these patients. Clinicians should consider false positive brucellosis seroreactivity in patients with active TB.Keywords: false positive serology, ELISA, diagnosis

Objectives: To study the outcome of intestinal tuberculosis presenting as acute abdomen. Study design: Descriptive Study. Place and Duration: Bolan Medical Complex Hospital (BMC) Quetta and Combined Military Hospital (CMH) Quetta from Nov 2003 to Nov 2005 from Bolan Medical Complex and from Nov 2005 to Nov 2006 in CMH Quetta. Material and Method: Thirty seven patients of acute abdomen presenting with intestinal obstruction were admitted; 28 from emergency department and 9 from out patient department. Twenty seven patients were from BMC and 10 from CMH Quetta. Patients were diagnosed as having abdominal tuberculosis on the basis of operative findings and histopathological reports. Results: Out of 37 patients presenting with acute abdomen due to intestinal obstruction, 54% were male and 46% were female with M: F ratio of 1: 1.2. Age of the patient ranged from 20 to 50 years, with maximum frequency between 30 to 40 years. Abdominal pain was the commonest presenting feature in all patients followed by constipation in 81.1% patients. Peritonism was seen in 27% patients. Different operative procedures performed were adhesionolysis 65.8%, segmental resection 7.9%, right hemicolectomy 10.5%, stricturoplasty 7.9% and ileostomy 1.3%. Mesenteric lymph node biopsy 40.8%. Conclusion: Intestinal tuberculosis is still a very important surgical problem in our country presenting as acute abdomen. A suspicion must always be kept during laparotomy and adequate tissue histopathology should supplement the diagnosis. (author)

To evaluate the diagnostic accuracy of bronchoscopy in patients with clinical or radiological suspicion of tuberculosis who were unable to produce sputum or with negative sputum smear microscopy results. A prospective cross-sectional study involving 286 patients under clinical or radiological suspicion of having pulmonary tuberculosis and submitted to bronchoscopy-BAL and transbronchial biopsy (TBB). The BAL specimens were submitted to direct testing and culture for AFB and fungi, whereas the TBB specimens were submitted to histopathological examination. Of the 286 patients studied, 225 (79%) were diagnosed on the basis of bronchoscopic findings, as follows: pulmonary tuberculosis, in 127 (44%); nonspecific chronic inflammation, in 51 (18%); pneumocystis, fungal infections, or nocardiosis, in 20 (7%); bronchiolitis obliterans organizing pneumonia, alveolites, or pneumoconiosis, in 14 (5%); lung or metastatic neoplasms, in 7 (2%); and nontuberculous mycobacterium infections, in 6 (2%). For the diagnosis of tuberculosis, BAL showed a sensitivity and a specificity of 60% and 100%, respectively. Adding the TBB findings significantly increased this sensitivity (to 84%), as did adding the post-bronchoscopy sputum smear microscopy results (total sensitivity, 94%). Minor post-procedure complications occurred in 5.6% of the cases. Bronchoscopy is a reliable method for the diagnosis of pulmonary tuberculosis, with low complication rates. The combination of TBB and BAL increases the sensitivity of the method and facilitates the differential diagnosis with other diseases.

Medical treatment for multidrug-resistant (MDR)-tuberculosis is complex, toxic, and associated with poor outcomes. Surgical lung resection may be used as an adjunct to medical therapy, with the intent of reducing bacterial burden and improving cure rates. We conducted an individual patient data metaanalysis to evaluate the effectiveness of surgery as adjunctive therapy for MDR-tuberculosis. Individual patient data, was obtained from the authors of 26 cohort studies, identified from 3 systematic reviews of MDR-tuberculosis treatment. Data included the clinical characteristics and medical and surgical therapy of each patient. Primary analyses compared treatment success (cure and completion) to a combined outcome of failure, relapse, or death. The effects of all forms of resection surgery, pneumonectomy, and partial lung resection were evaluated. A total of 4238 patients from 18 surgical studies and 2193 patients from 8 nonsurgical studies were included. Pulmonary resection surgery was performed on 478 patients. Partial lung resection surgery was associated with improved treatment success (adjusted odds ratio [aOR], 3.0; 95% confidence interval [CI], 1.5-5.9; I(2)R, 11.8%), but pneumonectomy was not (aOR, 1.1; 95% CI, .6-2.3; I(2)R, 13.2%). Treatment success was more likely when surgery was performed after culture conversion than before conversion (aOR, 2.6; 95% CI, 0.9-7.1; I(2)R, 0.2%). Partial lung resection, but not pneumonectomy, was associated with improved treatment success among patients with MDR-tuberculosis. Although improved outcomes may reflect patient selection, partial lung resection surgery after culture conversion may improve treatment outcomes in patients who receive optimal medical therapy. © The Author 2016.

In spite of the high prevalence of tuberculosis worldwide, there are only a few studies on its psychiatric complications such as suicidal behaviour. We undertook this study to assess the prevalence of suicidal behaviour and its associated factors among tuberculosis patients in public primary care in South Africa. In a cross-sectional survey conducted in three provinces of South Africa new TB and new re-treatment patients were assessed within one month of anti-tuberculosis treatment. The sample included 4900 (54.5% men and women 45.5%) consecutively selected tuberculosis patients from 42 public primary care clinics in three districts in South Africa. A total of 322 patients (9.0%) reported suicidal ideation and 131 (3.1%) had a history of a suicide attempt. In multivariate analysis female gender [Odds Ratio (OR)= 0.56, Confidence Interval (CI)= 0.43-0.74], psychological distress (OR=2.36, CI=1.04-2.29), post-traumatic stress disorders (PTSD) (OR=4.98, CI=3.76-6.59), harmful alcohol use (OR=1.97, CI=1.25-3.09) and being a TB re-treatment patient (OR=1.76, CI=1.32-2.34) were associated with suicidal ideation, and psychological distress (OR=3.27, CI=1.51-7.10), PTSD symptoms (OR=4.48, CI=3.04-6.61) and harmful alcohol use (OR=3.01, CI=1.83-4.95) were associated with a suicide attempt. Our findings suggest that co-morbid illnesses of psychological distress, PTSD and harmful alcohol use and HIV infection should be assessed in TB patients under TB control programmes to prevent suicidal behaviour. Clinicians should be aware about suicidality in tuberculosis patients to reduce mortality.

Full Text Available Background: Drug-resistant tuberculosis is one of major current challenges to global public health. The transmission of resistant strains is increasing as a burden of multidrug-resistant tuberculosis (MDR-TB patients in extra pulmonary tuberculosis (EPTB cases in India. Aim and Objectives: The aim was to study trends of anti-tuberculosis drug resistance pattern in new cases and previously treated cases of EPTB in referral hospitals in northern India. Study Design and Setting: A prospectively observational study and referral medical institutions in northern India. Materials and Methods: All EPTB specimens were processed for Ziehl Neelsen staining, BACTEC culture and BACTEC NAP test for Mycobacterium tuberculosis complex. All M. tuberculosis complex isolates were performed for radiometric-based drug susceptibility pattern against streptomycin, isoniazid, rifampicin and ethambutol using the 1% proportion method. Results: We found that 165/756 (20.5% isolates were identified as M. tuberculosis complex by the NAP test. We observed that 39.9% were resistant to first-line antitubercular drugs. The resistance rate was higher in previously treated patients: H (30.3%, R (16.3%, E (15.7% and S (16.3%. MDR-TB was observed in 13.4%, but, in new cases, this was 11.4% and 19.1% of the previously treated patients (P<0.05. Conclusion: MDR-TB is gradually increased in EPTB cases and predominant resistance to previous treated cases of EPTB. The molecular drug sensitivity test (DST method can be an early decision for chemotherapy in MDR-TB patients. The International Standards of TB Care need to be used by the RNTCP and professional medical associations as a tool to improve TB care in the country.

Several past and recent investigations have focused on the determination of tumor markers in pleural fluids to assess their Usefulness as less invasive replacement method of diagnosis. In this regard, few studies have dealt with the determination of the tumor marker, neuron specific enolase (NSE), in pleural fluids of patients suffering from both benign and malignant diseases such as non small cell lung carcinoma( NSCLC), small cell lung carcinoma( SCLC) and tuberculosis. Therefore, the present study was undertaken to establish the diagnostic utility of NSE in malignant condition by assessing levels in serum and pleural fluids of patients with lung cancer and by comparing it with a benign pulmonary disease of tuberculosis. Pleural fluids were obtained from 22 patients with carcinomatous pleurisy due to SCLC, 11 patients with carcinomatous pleurisy due to non-small cell lung cancer, and 30 patients with tuberculosis pleurisy for comparison purpose. Determination of NSE levels was performed by ECL technology according to the manufacturer's instructions. NSE levels of pleural fluids from SCLC patients were significantly elevated( P<0.0001) when compared with pleural fluids from NSCLC and tuberculosis patients. Moreover, pleural fluids of all 30 tuberculosis patients and 11 NSCLC patients showed moderate significance ( P< O.05 and P < 0.01, respectively) when compared with each other. In addition, cumulative results of NSE levels from SCLC and NSCLC combined also showed high significance (P<0.001) as compared to pleural fluids of tuberculosis patients and moderate significance (P<0.01) when compared with serum levels of both malignant and benign groups. It is concluded that determination of NSE levels in pleural fluids of lung cancer patients noted to be an effective diagnostic tool to differentiate carcinomatous pleurisy due to SCLC from those occurring due to NSCLC and tuberculosis. Further studies with larger group of patients are under progress to further establish

Information on drug resistance and transmission patterns of tuberculosis (TB) in foreign-born patients is lacking in Asia where immigration is increasing. We examined the drug-resistance profiles of 288 Mycobacterium tuberculosis isolates from foreign-born patients in South Korea, and assessed for potential transmission in the host country by analysing their IS6110 genotypes, as well as those of 4780 strains from native Korean TB patients. The prevalence of multidrug-resistant (MDR) TB was 9.7% and 42% among new and previously treated patients, respectively. Chinese nationality was associated with MDR TB (OR(China)=3.0, 95% CI 1.1-9.3). Of the 288 strains, 51 (17.7%) formed 31 clusters, of which 22 were identical to strains from native Koreans. A number of strains belonged to the K family, subtypes known to occur endemically in Korea. MDR TB was common, and clustering patterns showed potential cross-cultural transmission among foreign-born TB patients. Further molecular epidemiological studies of all isolates in the area are needed to determine the extent of international TB transmission in Asia. © 2011 SGM

Objective Identify and analyze the factors associated to length of hospital stay among HIV positive and HIV negative patients with tuberculosis in Manaus city, state of Amazonas, Brazil, in 2010. Methods Epidemiological study with primary data obtained from monitoring of hospitalized patients with tuberculosis in Manaus. Data were collected by interviewing patients and analyzing medical records, according to the following study variables age, sex, co-morbidities, education, race, income, lifestyle, history of previous treatment or hospitalization due to tuberculosis, treatment regimen, adverse reactions, smear test, clinical form, type of discharge, and length of hospital stay. The associated factors were identified through chi-square or t-Student test at a 5% significance level. Results Income from 1 to 3 minimum wages (P = 0.028), pulmonary tuberculosis form (P = 0.011), negative smear test or no information in this regard (P = 0.014), initial 6-month treatment scheme (P = 0.029), and adverse drug reactions (P = 0.021) were associated to prolonged hospital stay in HIV positive patients. Conclusion We found out that although there were no significant differences in the length of hospital stay in HIV positive patients, all factors significantly associated to prolonged hospital stay occurred in this group of patients. This finding corroborates other studies indicating the severity of tuberculosis in HIV patients, which may also contribute to lengthen their hospital stay. PMID:23593227

A county in Jiangsu Province, China. To estimate the costs of the diagnosis and treatment of tuberculosis (TB) from the patient's perspective and to identify determinants of the patient's financial burden. In a cross-sectional survey, we interviewed 316 patients diagnosed from January 2010 to May 2011 who had already completed their anti-tuberculosis treatment. The financial burden on TB patients included out-of-pocket costs and productivity losses. The average per capita total out-of-pocket cost was 3024.0 Chinese yuan (CNY), with a median cost of 1086 CNY (interquartile range [IQR] 480-2456). Mean out-of-pocket medical and non-medical costs were respectively 2565.7 CNY and 458.3 CNY. Productivity lost by patients and family members was 2615.2 CNY (median 500, IQR 250-2025). Factors associated with out-of-pocket costs and productivity losses included hospitalisation, adverse drug reactions, cost of drugs to 'protect' the liver, cost of second-line anti-tuberculosis drugs and diagnostic delay. Although the government of China has implemented a 'free TB service policy', the economic burden on patients is still heavy. More patient-centred interventions are essential to reduce the financial burden on patients.

Objective: To find out the average duration from onset of symptoms to the diagnosis and treatment of tuberculosis, reasons for diagnostic delay, its consequences, association of variables and formulation of recommendations. Results: In this study it was found that average time from onset of initial symptoms to diagnosis and treatment of tuberculosis was 120 days. In 64% of the patients medical practitioners were responsible for delaying the diagnosis of tuberculosis. Loss of weight in 40% and haemoptysis is 21% were the consequences of diagnostic delay of tuberculosis. Delay in the diagnosis of tuberculosis was statistically significant in those patients who consulted private practitioners, and consequences of tuberculosis were severe in those patients who consulted late.

The inflammatory profile of chronic obstructive pulmonary disease (COPD) related to tobacco is known in certain studies while that of the post tuberculosis form is not yet known. This study aimed to evaluate the levels of neutrophils, macrophages and lymphocytes cells in sputum of COPD patients with history of smoking or anterior tuberculosis. Enumeration of cells in samples was analyzed using standard microscopy. We enrolled 92 participants, 46 (50%) were COPD subjects comprising 22 (47.83%) smokers and 24 (52.17%) with anterior tuberculosis while 46 (50%) healthy persons constituted the control group. The levels of neutrophils, lymphocytes and monocytes were statistically higher in COPD patients compared to the control group with p-values of 0.0001 respectively. Neutrophils levels were higher in COPD patients with history of tobacco than in COPD patients with anterior tuberculosis with a mean rate of 4.72 × 10 6 /ml and 2.48 × 10 6 /ml respectively (p = 0.04). The monocytes and lymphocytes levels were not statistically different between the two sub-groups of COPD patients with p-value of 0.052 and 0.91 respectively. Neutrophils are the only inflammatory cells that were significantly higher in COPD patients with history of smoking as compared to COPD patients with anterior tuberculosis.

Case report of lymph nodal, hepatic and splenic tuberculosis in an HIV-positive patient

Bianca Barone

Full Text Available We describe a case of a male patient, 38 years old, HIV-positive (most recent CD4 count about 259/mm³, with abdominal pain, nausea, vomiting, anorexia, weight loss, and vespertine high fever with chills. His hemogram showed normocytic and normochromic anemia, with a high erythrocyte sedimentation rate (ESR and gross granulations in the neutrophils. Transaminases were normal. Bone marrow biopsy evidenced a chronic disease anemia pattern and a lack of infectious agents. Abdominal ultrasound examination showed a normal-size spleen, which exhibited heterogeneous parenchyma and multiple small hypoechoic images, together with small ascites, peripancreatic and para-aortic lymphadenopathy. These findings were confirmed by abdominal CT. The liver was normal in size, but had a hyperechoic image, which was not visualized on CT. Histopathological analysis of one of the multiple abdominal lymph nodes obtained by laparoscopic biopsy exhibited a chronic granulomatous inflammatory process, with caseous necrosis. Tissue sections were positive for BAAR (acid-alcohol-resistant bacillus, and the cultures were positive for Mycobacterium tuberculosis. Anti-tuberculosis treatment was begun, and the patient evolved with improvement of his general state, fever remission and weight gain. Splenic tuberculosis is a rare disease, occurring predominantly in patients in late stages of AIDS and/or disseminated tuberculosis. It is a difficult diagnosis, since there are no specific findings. Hence, complementary examinations, such as abdominal ultrasound/ CT, or fine needle aspiration, are usually necessary for investigation and differential diagnosis. Often, lesion regression after anti-tuberculosis regimens can be seen, and splenectomy is restricted to complicated or refractory disease.

Sacroiliac tuberculosis – A neglected differential in refractory low back pain – Our series of 35 patients

Science.gov (United States)

Prakash, Jatin

2014-01-01

Introduction Osteo-articular tuberculosis accounts for 1–3% of which 5–8% involves sacro-illiac joint. Isolated sacroiliac involvement is very rare. It usually presents as vague back pain. Plain radiographs are often inconclusive. Due to rarity of lesion, vague symptoms and non-conclusive X-rays the diagnosis is further delayed. We present a series of 35 patients presented with sacroiliac tuberculosis. Methods 35 patients were diagnosed of sacroiliac tuberculosis from January 2008 to December 2011. After a thorough history and clinical examination, patients were taken up for X-rays and MRI scans. Ultrasound guided needle aspiration was done from suspected area. After histological confirmation of the diagnosis, patients were treated with anti tubercular therapy. Results Persistent low back pain and difficulty with walking were noted in all patients. There were 21 males (60%) and 14 females and the age ranged from 22 to 55 years (mean: 27 years). Most of the patients (91.4%) had unilateral disease (32 patients). Results of conservative management were good. 21 (60%) of our patients achieved bony ankylosis at the end of study. 9 patients did not respond to conservative management where surgical debridement was done. 4 of these cases had MDR tuberculosis. Conclusion Sacroiliac tuberculosis must be kept as a differential in all refractory low back pain particularly in endemic areas. MRI is very helpful in early diagnosis of disease. In the early stages of the infection aspiration using a closed needle biopsy is recommended. An open biopsy is essential when the aspirate yields no growth. Open debridement should be done in those not responding to conservative management. PMID:25983488

Full Text Available The aim of this study was to analyse the clinical, epidemiological and bacteriological features present in 60 pulmonary tuberculosis patients who were also infected with human immunodeficiency virus (HIV and to compare these with 120 TB patients who were not infected with HIV. The patients with pulmonary tuberculosis and HIV coinfection were mostly male (p = 0.001, showed a higher frequency of weight loss >10 kilos (p <0.001, had a higher rate of non-reaction result to the tuberculin skin test (p <0.001, a higher frequency of negative sputum smear examination for acid-fast bacilli (p = 0.001 and negative sputum culture for Mycobacterium tuberculosis (p = 0.001. Treatment failure was more common in those who were HIV positive (p <0.000. No higher frequency of resistance to antituberculosis drugs was found to be associated with TB/HIV coinfection (p = 0.407. Association between extrapulmonary and pulmonary tuberculosis was more frequent in those seropositive to HIV than those without HIV virus, 30% and 1.6% respectively. These findings showed a predominance of atypical clinical laboratory features in co-infected patients, and suggest that health care personnel should consider the possibility this diagnosis.

Pathogen-targeted transcriptional profiling in human sputum may elucidate the physiologic state of Mycobacterium tuberculosis (M. tuberculosis) during infection and treatment. However, whether M. tuberculosis transcription in sputum recapitulates transcription in the lung is uncertain. We therefore compared M. tuberculosis transcription in human sputum and bronchoalveolar lavage (BAL) samples from 11 HIV-negative South African patients with pulmonary tuberculosis. We additionally compared these clinical samples with in vitro log phase aerobic growth and hypoxic non-replicating persistence (NRP-2). Of 2179 M. tuberculosis transcripts assayed in sputum and BAL via multiplex RT-PCR, 194 (8.9%) had a p-value <0.05, but none were significant after correction for multiple testing. Categorical enrichment analysis indicated that expression of the hypoxia-responsive DosR regulon was higher in BAL than in sputum. M. tuberculosis transcription in BAL and sputum was distinct from both aerobic growth and NRP-2, with a range of 396-1020 transcripts significantly differentially expressed after multiple testing correction. Collectively, our results indicate that M. tuberculosis transcription in sputum approximates M. tuberculosis transcription in the lung. Minor differences between M. tuberculosis transcription in BAL and sputum suggested lower oxygen concentrations or higher nitric oxide concentrations in BAL. M. tuberculosis-targeted transcriptional profiling of sputa may be a powerful tool for understanding M. tuberculosis pathogenesis and monitoring treatment responses in vivo.

The present study is to investigate the relationship between microRNA (miR)-365 expression and the levels of interleukin (IL)-6 mRNA and protein in patients with active tuberculosis. From June 2011 to June 2014, 48 patients with active pulmonary tuberculosis induced by Mycobacterium tuberculosis were included in the study. In addition, 23 healthy subjects were enrolled as control. Macrophages were collected by pulmonary alveolus lavage. In addition, serum and mononuclear cells were isolated from peripheral blood. The levels of miR-365 and IL-6 in macrophages, mononuclear cells and serum were determined using quantitative real-time polymerase chain reaction. The protein expression of IL-6 in macrophages and mononuclear cells was measured using Western blotting, while that in serum was detected by enzyme-linked immunoabsorbent assay. Expression of IL-6 mRNA and protein was significantly enhanced in patients with active pulmonary tuberculosis. Increase of IL-6 protein concentration in serum was probably due to the release of IL-6 protein from mononuclear cells in the blood. In addition, miR-365 levels were significantly lowered in patients with active pulmonary tuberculosis. Up-regulated IL-6 expression in macrophages, mononuclear cells and serum in patients with active pulmonary tuberculosis is related to the down-regulation of miR-365, suggesting that miR-365 may regulate the occurrence and immune responses of active pulmonary tuberculosis via IL-6.

Full Text Available To study the clinical efficiency of using mesodiencephalic modulation (MDM as therapy in the combination treatment of patients with pulmonary tuberculosis, the authors examined two groups: 1 the patients who received a MDM cycle in combination with chemotherapy regimens (a study group; 2 those treated using standard chemotherapy regimens (a control group. By the end of one-month therapy, the study group ceased bacterial excretion twice more often than the control group that exhibited the similar results only by the end of three-month treatment. MDM as therapy produced positive X-ray changes in 76.0% of the cases in the study group and in 44.4% in the control one. MDM used in the combination treatment of patients with tuberculosis makes it possible to reduce the length of hospital stay, the number of round-the-clock beds, and the cost of treating these patients.

Full Text Available Breast tuberculosis is a rare form of extrapulmonary tubercular infection. Our aim is to highlight the nonspecific clinical presentations, diagnostic difficulties and therapeutic approaches of mammarian tuberculosis. Forty-six patients diagnosed with breast tuberculosis between 2005 and 2015 were reviewed retrospectively. Clinical features, all diagnostic methods, and the outcomes of treatment were analysed. All cases were female with a mean age of 36.4 years. Breast mass and pain were the most common complaints. While 34.8% of the cases had a physical examination with suspicions for malignancy, 43.5% of the patients had Breast Imaging Reporting and Data System (BI-RADS 4 or 5 lesions suggested malignancy radiologically. Definitive diagnosis was based on histopathologic examination through core needle biopsy (n = 29, excisional biopsy (n = 12, and open biopsy (n = 5 taken from the abscess wall during drainage. Standard antiTB therapy for 6 months was given to all cases. Thirty-three patients recovered with standard 6-month therapy while extended treatment for 9–12 months was needed in 13 (28.2% cases. Surgery was carried out in 17 cases. Two patients developed recurrence. Breast tuberculosis can be easily confused with breast cancer, suppurative abscess, and other causes of granulomatous mastitis, both clinically and radiologically. A multidisciplinary approach is required to prevent diagnostic delays and unnecessary surgical interventions. Although antiTB therapy is the mainstay treatment of breast TB, surgery is usually indicated in patients refractory to medical treatment.

Full Text Available Background: Tuberculosis is one of the deadly communicable diseases which claim the lives of millions in the world. Early case detection and prompt treatment cures the patients, breaks the transmission and improves the control program. Objective: The aim of this study was to investigate the factors affecting tuberculosis case detection in Kersa District, south west Ethiopia. Method: Facility based cross sectional study design was employed in four directly observed treatment short course service providing public health centers. Three hundred eighty four patient folders were reviewed. In-depth interviews was conducted with 18 health care workers including heads of health centers, tuberculosis focal persons, clinicians, laboratory technicians, tuberculosis program coordinator and head of health office. Result: Significant number, 135(35.2% of tuberculosis suspects were not requested for microscopic examination of sputum smear, the laboratory results 21(8.4% of requested patients were not recorded in both patient folders and laboratory registers. Only 10 (4.4% of those examined and recorded were smearing positive. Participants described that the shortage and irregular supply of acid fast bacilli reagents and consumable, inadequate infrastructures, frequent electricity interruption, shortage of trained care providers, negligence of care providers, weakness of laboratory quality assurance system and poor health information use culture were major factors for low case identification. Conclusion: The resource shortage, electricity interruption, low commitment of care providers, weak quality assurance practice and poor health information use culture were major factors for low tuberculosis case identification and should be considered.

Full Text Available Tuberculosis is still one of the leading causes of mortality and morbidity. Besides clinical impact, the disease affects the quality of life (QOL too. With the rise of 21st century, multi-drug-resistant TB (MDR TB has risen as a significant public health problem due to emergence of resistance to anti-tuberculosis therapy (ATT drugs. This study was planned to analyze the impact of MDRTB on QOL. It was a six month analysis, with a sample size of 60 cases each of MDRTB and PTB. It was based on a pre-designed, pre-tested questionnaire using WHOQOL BREF scale.  Out of each group, 38 (63.33% and 36 (60.0% were in the 21-40 years of age groups, more than 60% married and were residing in the urban/urban slums. It was found that QoL of MDRTB patients was worse than PTB counterparts. The psychological and environmental domains (MDRTB vs. PTB 17.46 vs. 15.23 and 22.00 vs 18.91 were more affected as compared to physical and social domains (19.03 vs 20.05 and 7.88 vs 9.61 in MDRTB and PTB. Financially, MDRTB patients were worst suffers as compared to PTB as former were not being covered under any program, while both groups are affected socially due to social stigma attached with the disease. Thus, there is a need to design an applicable, reliable measure to better address the quality issues methodologically. This would further enable the health care professionals and management to devise relevant interventions to improve the quality of the patients, as well as the programme.

Background Tuberculosis (TB) patients face substantial delays prior to treatment initiation, and out of pocket (OOP) expenditures often surpass the economic productivity of the household. We evaluated the pre-diagnostic cost and health seeking behaviour of new adult pulmonary TB patients registered at Primary Health Centres (PHCs) in Vellore district, Tamil Nadu, India. Methods This descriptive study, part of a randomised controlled trial conducted in three rural Tuberculosis Units from Dec 2012 to Dec 2015, collected data on number of health facilities, dates of visits prior to the initiation of anti-tuberculosis treatment, and direct OOP medical costs associated with TB diagnosis. Logistic regression analysis examined the factors associated with delays in treatment initiation and OOP expenditures. Results Of 880 TB patients interviewed, 34.7% presented to public health facilities and 65% patients sought private health facilities as their first point of care. The average monthly individual income was $77.79 (SD 57.14). About 69% incurred some pre-treatment costs at an average of $39.74. Overall, patients experienced a median of 6 days (3–11 IQR) of time to treatment initiation and 21 days (10–30 IQR) of health systems delay. Age ≤ 40 years (aOR: 1.73; CI: 1.22–2.44), diabetes (aOR: 1.63; CI: 1.08–2.44) and first visit to a private health facility (aOR: 17.2; CI: 11.1–26.4) were associated with higher direct OOP medical costs, while age ≤ 40 years (aOR: 0.64; CI: 0.48–0.85) and first visit to private health facility (aOR: 1.79, CI: 1.34–2.39) were associated with health systems delay. Conclusion The majority of rural TB patients registering at PHCs visited private health facilities first and incurred substantial direct OOP medical costs and delays prior to diagnosis and anti-tuberculosis treatment initiation. This study highlights the need for PHCs to be made as the preferred choice for first point of contact, to combat TB more efficiently. PMID

Objective To determine whether implementation of provider-initiated HIV counseling would increase the proportion of tuberculosis patients that received HIV counseling and testing. Design Cluster-randomized trial with clinic as unit of randomization Setting Twenty, medium-sized primary care TB clinics in the Nelson Mandela Metropolitan Municipality, Port Elizabeth, Eastern Cape Province, South Africa Subjects A total of 754 adults (≥ 18 years) newly registered as tuberculosis patients the twenty study clinics Intervention Implementation of provider-initiated HIV counseling and testing. Main outcome measures Percentage of TB patients HIV counseled and tested. Secondary Percentage of patients HIV test positive and percentage of those that received cotrimoxazole and who were referred for HIV care. Results A total of 754 adults newly registered as tuberculosis patients were enrolled. In clinics randomly assigned to implement provider-initiated HIV counseling and testing, 20.7% (73/352) patients were counseled versus 7.7% (31/402) in the control clinics (p = 0.011), and 20.2 % (n = 71) versus 6.5% (n = 26) underwent HIV testing (p = 0.009). Of those patients counseled, 97% in the intervention clinics accepted testing versus 79% in control clinics (p =0.12). The proportion of patients identified as HIV-infected in intervention clinics was 8.5% versus 2.5% in control clinics (p=0.044). Fewer than 40% of patients with a positive HIV test were prescribed cotrimoxazole or referred for HIV care in either study arm. Conclusions Provider-initiated HIV counseling significantly increased the proportion of adult TB patients that received HIV counseling and testing, but the magnitude of the effect was small. Additional interventions to optimize HIV testing for TB patients urgently need to be evaluated. PMID:18520677

The chest x-ray radiological features of tuberculosis patients are well documented, and the radiological features that change in response to successful pharmaceutical therapy can be followed with longitudinal studies over time. The patients can also be classified as either responsive or resistant to pharmaceutical therapy based on clinical improvement. We have retrospectively collected time series chest x-ray images of 200 patients diagnosed with tuberculosis receiving the standard pharmaceutical treatment. Computer algorithms can be created to utilize image texture features to assess the temporal changes in the chest x-rays of the tuberculosis patients. This methodology provides a framework for a computer-assisted detection (CAD) system that may provide physicians with the ability to detect poor treatment response earlier in pharmaceutical therapy. Early detection allows physicians to respond with more timely treatment alternatives and improved outcomes. Such a system has the potential to increase treatment efficacy for millions of patients each year.

Full Text Available Background & objectives: In spite of the high prevalence of tuberculosis worldwide, there are only a few studies on its psychiatric complications such as suicidal behaviour. We undertook this study to assess the prevalence of suicidal behaviour and its associated factors among tuberculosis patients in public primary care in South Africa. Methods: In a cross-sectional survey conducted in three provinces of South Africa new TB and new re-treatment patients were assessed within one month of anti-tuberculosis treatment. The sample included 4900 (54.5% men and women 45.5% consecutively selected tuberculosis patients from 42 public primary care clinics in three districts in South Africa. Results: A total of 322 patients (9.0% reported suicidal ideation and 131 (3.1% had a history of a suicide attempt. In multivariate analysis female gender [Odds Ratio (OR= 0.56, Confidence Interval (CI= 0.43-0.74], psychological distress (OR=2.36, CI=1.04-2.29, post-traumatic stress disorders (PTSD (OR=4.98, CI=3.76-6.59, harmful alcohol use (OR=1.97, CI=1.25-3.09 and being a TB re-treatment patient (OR=1.76, CI=1.32-2.34 were associated with suicidal ideation, and psychological distress (OR=3.27, CI=1.51-7.10, PTSD symptoms (OR=4.48, CI=3.04-6.61 and harmful alcohol use (OR=3.01, CI=1.83-4.95 were associated with a suicide attempt. Interpretation & conclusions: Our findings suggest that co-morbid illnesses of psychological distress, PTSD and harmful alcohol use and HIV infection should be assessed in TB patients under TB control programmes to prevent suicidal behaviour. Clinicians should be aware about suicidality in tuberculosis patients to reduce mortality.

Use of rhu-GM-CSF in pulmonary tuberculosis patients: results of a randomized clinical trial

Diana Brasil Pedral-Sampaio

Full Text Available It has been postulated that deficient or incomplete clinical and/or microbiological response to tuberculosis treatment is associated with cell-mediated immunological dysfunction involving monocytes and macrophages. A phase 2 safety trial was conducted by treating patients with either recombinant human granulocyte-macrophage colony-stimulating factor (rhu-GM-CSF or a placebo, both in combination with anti-tuberculosis chemotherapy. Thirty-one patients with documented pulmonary tuberculosis were treated with rifampin/isoniazid for six months, plus pyrazinamide for the first two months. At the beginning of treatment, rhu-GM-CSF (125µg/M² was randomly assigned to 16 patients and injected subcutaneously twice weekly for four weeks; the other 15 patients received a placebo. The patients were accompanied in the hospital for two weeks, then monthly on an out patient basis, for 12 months. Clinical outcomes were similar in both groups, with no difference in acid-fast bacilli (AFB clearance in sputum at the end of the fourth week of treatment. Nevertheless, a trend to faster conversion to negative was observed in the rhu-GM-CSF group until the eighth week of treatment (p=0.07, after which all patients converted to AFB negative. Adverse events in the rhu-GM-CSF group were local skin inflammation and an increase in the leukocyte count after each injection, returning to normal 72 hours after rhu-GM-CSF injection. Three patients developed SGOP and SGPT > 2.5 times the normal values. All patients included in the GM-CSF group were culture negative at six months, except one who had primary TB resistance. None of the patients had to discontinue the treatment in either group. We conclude that rhu-GM-CSF adjuvant immunotherapy could be safely explored in a phase 3 trial with patients who have active tuberculosis.

A phase 2 safety trial was conducted by treating patients with either recombinant human granulocyte-macrophage colony-stimulating factor (rhu-GM-CSF or a placebo, both in combination with anti-tuberculosis chemotherapy. Thirty-one patients with documented pulmonary tuberculosis were treated with rifampin/isoniazid for six months, plus pyrazinamide for the first two months. At the beginning of treatment, rhu-GM-CSF (125µg/M² was randomly assigned to 16 patients and injected subcutaneously twice weekly for four weeks; the other 15 patients received a placebo. The patients were accompanied in the hospital for two weeks, then monthly on an out patient basis, for 12 months. Clinical outcomes were similar in both groups, with no difference in acid-fast bacilli (AFB clearance in sputum at the end of the fourth week of treatment. Nevertheless, a trend to faster conversion to negative was observed in the rhu-GM-CSF group until the eighth week of treatment (p=0.07, after which all patients converted to AFB negative. Adverse events in the rhu-GM-CSF group were local skin inflammation and an increase in the leukocyte count after each injection, returning to normal 72 hours after rhu-GM-CSF injection. Three patients developed SGOP and SGPT > 2.5 times the normal values. All patients included in the GM-CSF group were culture negative at six months, except one who had primary TB resistance. None of the patients had to discontinue the treatment in either group. We conclude that rhu-GM-CSF adjuvant immunotherapy could be safely explored in a phase 3 trial with patients who have active tuberculosis.

Conclusion: Hyponatraemia, hyperkalaemia, and hypochloremia characterized some of the electrolyte imbalance among TB patients receiving treatments. The raised level of bicarbonate may be attributed to overcorrection of respiratory acidosis often found in patients with tuberculosis. Monitoring electrolytes is therefore an important component of TB management.

The outcome of the chemotherapy for pulmonary, extraplumonary and disseminated tuberculosis is not well documented, especially in developing countries. This study assessed tuberculosis treatment outcome, cure-to-treatment ratio and mortality among all types of tuberculosis patients in a tertiary care setting in Saudi Arabia. All cases diagnosed and treated for active Mycobacterium tuberculosis infection between 1991 and 2000 were included retrospectively. Data collected included type of tuberculosis involvement, treatment outcome, relapse and co-morbidities. Over a ten-year period, 535 case of tuberculosis were diagnosed and treated. Isolated pulmonary tuberculosis was identified in 141 cases (26.4%), extrapulmonary tuberculosis in 339 cases (63.3%). Co-morbidities were noted in 277 (52%) patients. Immunosuppression was found in 181 (34%) cases. The cure rate was 82%. The cure-to-treatment ratio was 86% in extrapulmonary tuberculosis and 65% in disseminated tuberculosis. Overall mortality was 18%. Disseminated tuberculosis had the highest mortality (34.9%), followed by pulmonary (21.8%), the extrapulmonary tuberculosis (13.6%). Forty-seven percent of all mortalities were directly related to tuberculosis. Relapse was documented in 14 out of 349 patients (4%) who had 24 months of follow-up. Despite tertiary care support, complicated tuberculosis carries a high mortality. Earlier diagnosis and complete appropriate chemotherapy are essential for improved outcome. (author)

Objective: To explore the clinical significance of the changes of serum IL-2, soluble IL-2 receptor (SIL-2R) and vascular endothelial growth factor (VEGF) levels in pediatric patients with tuberculosis. Methods: Serum IL-2 (with RIA) and SIL-2R, VEGF (with ELISA) levels were determined in 68 pediatric patients with tuberculosis (30 active and 38 non- active) and 30 controls. Results: In the patients with active tuberculosis, the serum IL-2 levels were significantly lower and SIL-2R, VEGF levels were significantly higher than those in the controls (P<0.01). Conclusion: Determination of serum IL-2, SIL-2R and VEGF levels was useful for monitoring the activity of tuberculosis in pediatric patients. (authors)

CC chemokine receptor-2 (CCR2) play important roles in inflammation. The CCR2 V64I polymorphism already reported associated with many diseases; however, the association of CCR2 V64I polymorphism with tuberculosis is still unknown. Also, there is no report about the presentation of CCR2 V64I polymorphisms in Indonesian tuberculosis patients with rifampicin-mono resistant status has ever been published, to the best of our knowledge. This study evaluated the presence of CCR2 V64I polymorphisms in Javanese rifampicin-mono resistant tuberculosis patients. In an ongoing molecular epidemiology study of human genomic polymorphisms and infection, 51 Javanese rifampicin-mono resistant tuberculosis patients in Dr. Moewardi General Hospital in Surakarta were enrolled in the study. The blood samples were aliquoted and fractionated. The nucleic acids were extracted from all blood samples and subjected to the CCR2 V64I polymorphisms detection by a polymerase chain reaction-sequence-specific primer (PCR-SSP) technique. PCR products were analyzed in 3% agarose. CCR2 64V and 64I homozygote were found in 23.5% (12/51) and 23.5% (12/51) blood samples, respectively. The CCR2 VI genotype was found in 52.9% (27/51) blood samples. The CCR2 VI genotype was found predominant in Javanese rifampicin-mono resistant tuberculosis patients and may have anassociation with the clinical progression.

Objective. To describe the imaging findings in sterno-clavicular tubercular involvement.Design and patients. Fifteen patients with pathologically proven tuberculosis of the sternum and clavicle were retrospectively evaluated. Routine radiography, computed tomography (CT) and magnetic resonance imaging (MRI) were used in some or all of the patients. Clinical information and imaging features were evaluated in each case.Results. Eight patients had sterno-clavicular joint (SCJ) involvement, five had isolated sternal involvement and two had isolated clavicular involvement. Seven patients were evaluated with only CT, six with only MRI and two with both. There were eight male and seven female patients, varying in age between 16 and 78 years. Fever, swelling and pain were common presenting symptoms. Two patients were HIV positive. Radiographs were positive in only eight patients. Destruction and signal intensity (SI) changes of the sternum and clavicle, destruction of the cartilage, soft tissue changes representing granulation tissue/abscess, displacement of the adjacent structures (vessels, trachea, etc.) and inflammatory changes in the adjacent structures in the form of cellulitis and myositis were common imaging features.Conclusions. All imaging methods can provide complementary information regarding sterno-clavicular tubercular involvement that is helpful for determination of the therapy. MRI is useful in determining the extent of the lesion, particularly marrow involvement and soft tissue extent. (orig.)
