Tuberculosis is a major infectious disease with a high mortality burden in the Asia-Pacific region and worldwide. Among various types of extrapulmonary tuberculosis, tuberculous pleuritis (TBP) is amongst the most common manifestations. TBP is also a major underlying cause among patients hospitalised with new-onset unilateral pleural effusion. The workup of TBP frequently involves thoracentesis to retrieve pleural fluid and pleural biopsy for microbiological and histological interpretations. However, the diagnostic accuracy of these tests is of unsatisfactory sensitivity, making diagnosing TBP challenging. In addition, certain tests, including pleural fluid adenosine deaminase (ADA), Mycobacterium tuberculosis polymerase chain reaction (MTB PCR), advanced biopsy procedures (e.g. real-time image-guided biopsy, pleuroscopy) are not readily available in developing regions due to scarcity of resources and lack of expertise. All these factors lead to heterogeneous practice in approaching new-onset pleural effusion, interpretation of pleural TB investigations, and timing of TBP treatment initiation among respiratory physicians in different Asia-Pacific regions. The proposed multinational survey aims to understand the real-world clinical practice in approaching patients with new-onset unilateral pleural effusion and diagnosing TBP in Asia-Pacific regions with intermediate to high TB burden. The results will reflect the current practice of diagnosing TBP, clinical and resource discrepancies in investigating TBP, management of TBP and help prioritise the need for further research in TBP
This study aims to assess the prevalence and the outcome of prescribing drugs known to have major drug-drug interactions with anti-tuberculous drugs among Kasr Alainy tuberculous patients.
The purpose of this study is to provide data showing if there are any effects of GSK3036656 on a combined oral contraceptive containing Ethinyl Estradiol (EE) and Levonorgestrel (LNG), which will help inform future studies on suitable contraceptive measures to be used.
The goal of this observational study is to understand how tuberculosis (TB) infection impacts the function and development of the placenta, and whether TB infection can contribute to pregnancy-related disorders through effects on the placenta. The main questions it aims to answer are: - Does TB infection affect the structure of the placenta? - Does TB infection affect the function of the placenta? Pregnant women attending delivery clinics in Addis Abeba, Ethiopia, will be enrolled and classified for TB infection using a blood-based test. We will compare the following outcomes between women with TB infection and women without TB infection: - Pathological lesions of the placenta - Gene and protein expression patterns linked to pregnancy-related disorders - Infant outcome at birth and at 6 weeks after birth
This study is a prospective observational non-randomized clinical trial where all the participitants undergo the same procedure and every participitant's samples are compared to each other. The investigators conduct EBUS TBNA and EBUS TBMCB on all the study participants.The cryobiopsy samples are numbered to evaluate the number of biopsies needed to reach a definite diagnosis and to assess the added value of every sample taken from the same participitant. Every participitant's own samples are compared to each other and added value of EBUS TBMCB is defined as the difference in diagnostic yield between the EBUS TBNA alone and the combination of EBUS TBNA with EBUS TBMCB. Diagnostic yield is defined as the efficacy of the investigation module in reaching a definite diagnosis (percentage of cases with a definite diagnosis). Follow up four weeks after the procedure to assess the risk for postoperative complications.
The overall objective of this Aim is to design and iteratively adapt a home-based, mHealth- and oral testing facilitated strategy for implementing tuberculosis (TB) contact tracing in Cali, Colombia. Investigators will employ an iterative, community-engaged, participatory co-design process to optimize the feasibility, acceptability, usability, and appropriateness of the mobile health (mHealth) and oral testing strategy, in preparation for a future, appropriately powered implementation-effectiveness trial. This protocol includes the baseline contact tracing protocol and the procedures for determining adaptations to the mHealth strategy (i.e., nominal group technique).
The goal of this clinical trial is to test two advices on alcohol drinking in more than 10.000 Spanish adult drinkers (men of 50 or more years and women of 55 or more years). The main question it aims to answer is to test the non-inferiority advice of a moderate alcohol drinking pattern on all-cause mortality and other chronic disease like cardiovascular disease, cancer or type 2 diabetes. Participants will receive during 4 years an advice to drink alcohol following a Mediterranean Alcohol Drinking Pattern (MADP): consuming alcohol in moderation, avoidance of binge drinking and preference for red wine. Researchers will compare those who will receive a MADP advice with those who will receive an advice on abstention to see if the advice on MADP is not inferior than the abstention advice to prevent all-cause mortality and other chronic diseases.
Individual pharmacokinetic variability is an important driver of tuberculosis (TB) treatment failure particularly among undernourished populations, and that suboptimal serum drug concentrations are associated with delayed response to treatment, death, and acquired bacterial drug resistance. Serum drug exposures can be approximated by urine excretion as measured by spectrophotometry, replacing the need for specialized equipment for serum testing. Anti-TB pharmacokinetic variability has also been associated with enteric pathogen burden. The overall hypothesis is that urine spectrophotometry will identify people with below-target rifampin serum concentrations, which can be corrected to target levels after dose adjustment as confirmed by serum mass spectrometry. Therefore, this protocol includes a clinical trial to assess efficacy and safety of rifampin dose adjustment based on urinary excretion levels among adults and children who are being treated for drug-sensitive pulmonary TB at our longstanding collaborative research site in Haydom Lutheran Hospital, Tanzania.
This randomized trial uses the evidence-based Systems Analysis and Improvement Approach (SAIA) adapted for tuberculosis (SAIA-TB) to assess the comprehensive tuberculosis (TB) care cascade across 16 clinics in rural Eastern Cape, South Africa to improve patient outcomes. The aims of this study are to: - Evaluate the effectiveness of SAIA-TB use in clinics on TB cascade outcomes for TB patients and with high-risk contacts - Determine the drivers of SAIA-TB implementation success or failure across clinics The investigators hypothesize that SAIA-TB implementation will lead to a 20% increase in each of: TB screening, TB preventive treatment initiation, and TB disease treatment initiation during the 18-month intervention period.
