Filter by:People who are infected with HIV and tuberculosis (TB) need to receive medications that treat both diseases safely and effectively. This study enrolled infants and children infected with HIV and TB and evaluated the safety and tolerance of an antiretroviral (ARV) treatment regimen for HIV that contains raltegravir when administered with a TB treatment regimen that includes rifampicin. Study researchers aimed to determine the most effective dose of raltegravir for infants and children when taken with rifampicin.
Tuberculosis is a bacterial infection causing 1.1 million deaths annually worldwide. Diagnosis of the disease is often time consuming or challenging. Many cases of tuberculosis require advanced and expensive diagnostic methods that restrict their availability in resource limited countries where the burden of tuberculosis is highest. The development of rapid point of care diagnostics is required. Published data confirm that trained African giant-pouched rats are able to identify M. tuberculosis cultures through olfactory recognition. A first trial using an electronic nose reported a rate of detection of 85% in tuberculosis patients. A further trial was closed in June 2011 but remains unpublished, yet. The olfactory pattern that potentially allows the recognition of tuberculosis remains unknown. This trial aims to detect first patterns of volatile organic compounds (VOCs) that bear a potential for further development and fine tuning. A technical prototypic device of Siemens is used for pattern detection. The study is comparing 3 groups of patients: - patients with confirmed active pulmonary tuberculosis (n=20) - patients with other inflammatory lung diseases (pneumonia, sarcoidosis, COPD, bronchial carcinoma) (n=20) - healthy volunteers that do not work in the hospital or visit the hospital regularly Detailed data for all study subjects will be collected for this trial in order to eliminate confounding factors. Furthermore, detailed data of the surroundings of the patient, the surroundings of the technical device and of the operator will be captured. Hypothesis: The pattern of exhaled volatile organic compounds allows the detection of pulmonary tuberculosis
The study is designed to test the hypothesis that BCG administration via jet injector will produce a comparable immune response and that there will be no significant differences in safety or reactogenicity between BCG administration via jet injector and needle and syringe. The primary objectives of this study are to... 1. Compare the safety and reactogenicity of BCG administered intradermally by a jet injector device in adults and infants, to BCG administered intradermally by needle and syringe; 2. Compare the specific T cell immunity in neonates vaccinated with BCG via the jet injector device to infants vaccinated with BCG via needle and syringe.
Previous studies of vitamin D supplementation have suggested there may be differences in response between individuals. This study is an open label study of vitamin D supplementation in patients with active or latent tuberculosis in which active disease patients take 100000units of vitamin D every 8 weeks during their tuberculosis treatment. Genotyping for relevant vitamin D pathway polymorphisms will be carried out and related to clinical and ex vivo markers of vitamin D response. Latent patients will only be studied for vitamin D response ex vivo. Our hypothesis is that response to vitamin D in both monocytes and T cells will be related to polymorphisms in the DBP gene, and that this may relate to clinical response in terms of post supplementation vitamin D level.
The proposed preliminary field evaluation will compare a point-of-care (POC) transaminase test with the standard of care test used in an HIV clinic at the Hospital for Tropical Diseases in Ho Chi Minh City, Vietnam.
The aim with study is to provide adjunctive therapy with vitamin D and phenylbutyrate together with standard anti-tuberculosis treatment to significantly improve clinical recovery among patients with untreated, active pulmonary tuberculosis.
In this study, Interactive Research and Development (IRD) in Karachi, Pakistan is evaluating the impact of Interactive Reminders on drug compliance and treatment outcomes. Interactive Reminders is an interactive SMS reminder system to help patients remember to take their TB medication. In this system, patients receive daily SMS reminders for the duration of their treatment at a pre-specified time, reminding them to take their medication. Patients are asked to reply back to the system, either through SMS or a missed call, with the time they took their medicine that day. If a response is not received within two hours, a second reminder is sent. If a response is still not received in a further two hours, a third and final reminder for the day is sent. Non-responsive patients are followed up with phone calls and a list of non-responsive patients is shared with clinics based on the parameters of non-responsiveness that they specify. IRD seeks to determine the impact of this system on treatment outcomes and compliance to prescribed medication through administering a randomized control trial among newly diagnosed TB patients in Karachi, Pakistan.
Primary Objective: - To evaluate the effect of single and repeated administration of rifapentine given as daily or weekly regimen on steady-state pharmacokinetic parameters of efavirenz, emtricitabine and tenofovir given as a fixed dose combination (ATRIPLA™ ). Secondary Objective: - To evaluate the safety and tolerability of concomitant administration of rifapentine and ATRIPLA™ given to HIV+ patients
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.
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.
