Tuberculosis (also known as TB) is a common infection and a major cause of death in children. Effective treatment using a combination of anti-tuberculosis (anti-TB) medications saves lives, but dosages of these medications are not well established in children. Several research studies have shown that the recommended dosages of the anti-TB medications in children do not lead to adequate blood levels to kill the bacteria in some children. This situation may lead to treatment failure and emergence of drug resistance. As a result, the world Health Organization (WHO) recently recommended increased dosages for all the TB medications in children. This study is being conducted to find out if the increased dosages of the anti-TB drugs are safe and lead to adequate drug levels in the blood of children with TB with or without HIV infection.
The purposes of this study 1. to compare the positivity of tuberculin skin test(TST) and QuantiFERON-TB Gold (QFT-G), and determine the level of agreement between two tests in patients with rheumatic diseases 2. to evaluate the difference in the occurrence of active TB in patients who receive both QFT-G and TST compared with those who receive only TST for detecting of Latent tuberculosis infection(LTBI) who are candidates of TNF inhibitors.
1. To investigate the difference of PE inflammation/apoptosis-associated markers between TB pleurisy and non-TB pleurisy 2. To investigate the difference of neutrophil apoptosis in exudative PE between TB pleurisy and non-TB pleurisy 3. To investigate the change of apoptosis pattern of PE neutrophil, before and after TB antigen stimulation, and compare the difference between TB pleurisy and non-TB pleurisy 4. To investigate diagnostic aid of the inflammation/apoptosis-associated markers and apoptosis pattern of PE neutrophil for tuberculous pleurisy
To follow-up the latent tuberculosis infection and evaluate the risk of developing active tuberculosis in patients with severe chronic kidney disease or receiving long-term dialysis
This trial will investigate the administration of two new tuberculosis vaccines, called AERAS-402 and MVA85A. The purpose of this trial is to assess what happens when both of these vaccines are given one after the other. The trial will assess the safety of both vaccines and also their ability to stimulate an immune response within the body. It is hoped that when these two vaccines are given in sequence, the combined immune response is even better than when each vaccine is used individually.
During the Study: - Subject is required to visit every week for the first 2 months and then every month till completion of study or as and when required - The usual symptomatic and supportive treatment of Chronic Liver Disease, including use of antiviral, will be given to all patients. - Effort will be made to avoid use of other hepatotoxic drug(s) during Anti-Tubercular Treatment. - Liver function tests (LFT) will be done weekly during first 2 months then at one month interval or as when required. - The treatment efficacy of Anti-Tubercular Treatment (ATT) will be made on the basis of clinical, biochemical, microbiological and imaging parameters at months 2, 4, 7 and 9. Patients not improving at 4 weeks after initiation of treatment will be shifted to alternative regimens and will be excluded from the study.
To compare the serum apoptosis-associated markers between patients with active TB and patients with LTBI To evaluate the efficiency of apoptosis-associated markers to differentiate potential of active TB from LTBI
This is a Phase I, single-center, double-blinded, randomized, placebo-controlled, five-period cross-over clinical study of PA-824 to evaluate the effect of PA-824 and of PA-824 plus moxifloxacin on cardiac repolarization (QT/QTc interval duration) in a total of 75 healthy male and female participants, aged 18 to 45 years. Moxifloxacin will be used as an active control. Participants will be blinded to the treatments they will receive. The study consists of a screening period up to 26 days; enrollment, 1 day; five in-patient treatment periods consisting of an admission day (except in the first treatment period, when the pre-dose day is the baseline), dosing day and two post-dosing days; an out-patient period of at least three days and not more than 10 days between treatment periods; and a final visit 7 - 14 days after discharge from the last treatment period.
The purpose of this study is to assess the safety and immunogenicity of two doses of the TB vaccine administered according to a 0, 1 month schedule. In, addition, blood samples collected at different time points after vaccination will be analysed to see when exactly genes are activated by the vaccine using an assay called mRNA expression profiling. The different methods for mRNA expression profiling using whole blood samples versus Peripheral Blood Mononuclear cell(s) (PBMCs), will also be compared.
