Filter by:This study aims to evaluate the utility of home-based point-of-care TB testing for early diagnosis and linkage to care of household contacts of TB patients, addressing the need for active case finding and early detection of infectious TB. The investigators propose an exploratory study to 1) investigate the acceptability and feasibility of home-based TB testing of household contacts using a new portable GeneXpert point-of-care (PoC) platform, and 2) determine the potential impact of such a home-based testing program on early detection of TB disease and linkage-to-care (LTC).
The objective of the present study is to confirm in a multicentric study the utility of our viability test in large cohort of smear-positive pulmonary tuberculosis patients under treatment and to determine if the test could help physicians to discontinue isolation measures in hospital setting.
Tuberculosis (TB) is currently one of the top 10 causes of death worldwide and the leading cause of death from a single infectious agent (ranking above HIV/AIDS). The investigators hypothesize that reducing respiratory exposure within the household, during the first weeks of TB treatment initiation of the index case, can reduce new TB infections in close contacts. For this purpose, a pilot, controlled, pre-post study will be set up, to evaluate the feasibility of implementing a bundle of respiratory precautions to all household contacts of new pulmonary TB cases, compared to standard of care, in primary health care in a high TB incidence area in Santiago, Chile.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the Coronavirus disease (COVID-19). Tuberculosis (TB) is the foremost cause of infectious deaths globally. In 2025, an additional 1.4 million TB deaths could occur as direct consequence of the COVID-19 pandemic. It is postulated that individuals with latent or active TB are more susceptible to SARS-CoV-2 disease and that COVID-19 disease rate is high in patients with active TB, although the evidence is still scarce. TB and SARS-CoV-2 are both infectious diseases which primarily attack the alveolar region of the lungs and share common symptoms. SARS-CoV-2 disease can induce innate and adaptive immunity, but uncontrolled inflammatory innate immunity and impaired adaptive immune responses may be associated with severe tissue damage, both locally and systemically. People with coinfection (COVID-19 and TB disease) might potentially have impaired protective immune responses and treatment outcomes, specifically as far as anti-tuberculosis treatment is concerned. However, very little is known about the immunological underpinnings in this interface between TB and COVID-19 on the effect of SARS-CoV-2 disease on disease severity, response to treatment and treatment outcomes in pulmonary tuberculosis. Investigators hypothesize that altered immunity due to prior or present asymptomatic disease with SARS-CoV-2 virus can lead to altered immune responses and systems biology, increased severity and altered treatment outcomes in TB disease. The main objective of the study would be to evaluate the baseline differences in immune cells populations immune cell responses at baseline and at the time of treatment (2nd month) and end of treatment. Further, Investigators would be evaluating the changes in proteomic profiles in a subset of these individuals. In addition, immunological assays examining differences in T cell populations, measuring levels of various cytokines and by immunophenotyping as well as other immune parameters related to innate and adaptive responses will be performed to enhance the understanding of the immunological cross-talk between active TB patients with or without SARS-CoV-2. The secondary objective would be to study the clinical features, disease severity, mycobacterial burden and treatment outcomes in a cohort of SARS-CoV-2 infected (asymptomatic PCR or Antibody+) and non-infected patients with active pulmonary TB.
The METHOD study will examine whether adding metformin to standard antibiotic treatment for tuberculosis (TB) in people with HIV is safe and well tolerated. The study will also test if adding metformin clears the infection more quickly and with less lung damage. When enrolled, participants will have an equal chance of being in the group that takes standard TB medicines alone or in the group that also takes metformin. Participants will have a chance to be put on either: 1) standard TB medicines (isoniazid, rifampicin, ethambutol and pyrazinamide for two months, continuing isoniazid and rifampin for four more months) only; or 2) the same standard TB medicines plus metformin. Participants randomized to the metformin arm will take metformin for eleven weeks, starting one week after starting the standard TB medicines. In addition to monitoring for side effects, all participants will have studies of drug levels and lung and immune function.
Prospective, randomized, double-blind, multicentre, placebo-controlled clinical phase IIb trial to evaluate efficacy of RUTI® vaccine in DS- (Drug-Sensitive) and MDR-TB (Multidrug-resistant) patients favourably responding to standard MDR-TB treatment. Time point of vaccination starts upon completion of 1 week of standard DS-TB treatment (cohort A), and another cohort of patients will be vaccinated upon completion of 1 month of standard MDR-TB treatment (cohort B). All the patients will be followed up to the end of the treatment.
This study is a Phase 1, single-center, open-label study to investigate the absorption, metabolism, and excretion of BTZ-043 after a single oral administration of 500 mg BTZ-043 containing 3.7 MBq of [14C]BTZ-043 in 4 healthy adult male subjects
A Phase 1, Partially-Blinded, Placebo-Controlled, Randomized, Multiple Ascending Dose Study to Include A Single Dose Food-Effect Study to Evaluate the Safety, Tolerability, and the PK Profile of TBI-223 in Healthy Subjects
Lung diseases are one of the most common causes of emergency room visits. There are very few tools that are able to predict which patients will have a worsening or increasing severity of their condition. There are also limited ways to check the health of patients with respiratory conditions at home and during the time between medical appointments. The ADAMM-RSMTM device records heart rate, breathing rate, temperature, cough and activity while wearing it. This study will test participants willingness to wear the device and perform ongoing monitoring to assess the possibility to predict the onset and increases in severity of their lung conditions.
The development of efficacious, safe, and shorter treatment regimens could significantly improve TB management and treatment success rates. This prospective, 3-year, single arm study is to evaluate the efficacy and safety of a short-course, 4-month regimen including isoniazid(H), pyrazinamide(P), rifapentine (P), and moxifloxacin(M) (2HZPM/2HPM) for the treatment of drug-susceptible, pulmonary tuberculosis, and compared with a historical control group receiving the standard six-month regimen.
