Filter by: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
Introduction: Tuberculosis (TB) infection is a key driver of the TB pandemic, with over 10.6 million people fell ill with TB disease in 2022. About one-quarter of the global population is estimated to be infected with TB bacteria. Around 5-10% of people with TB infection will develop active and contagious TB disease, which could be largely avoided if TB infection is identified and given effective preventative treatment, before progression to active disease. The long treatment of TB infection with regimens lasting from three to nine months is a significant barrier to treatment completion in individuals with a confirmed diagnosis of TB infection. Adapting a shorter regimen than the current regimens could lead to a higher treatment completion rate and increased uptake of preventative therapy for TB, as well as reduced side effects. Methods and analysis: An open-label, randomized clinical trial (1:1) will be performed in two study sites in Ha Noi, Vietnam (Vietnam National Lung Hospital and Ha Noi Lung Hospital). Adult household contacts (n=350) of people with new, bacteriologically-confirmed, pulmonary, drug-susceptible TB who initiate treatment will be invited to participate. Aim: To compare the TB preventive therapy completion rates and adverse event incidence between a new one-month regimen (1HP) versus the current three-month regimen (3HR)*. *1HP= one month of daily isoniazid (H/INH) and rifapentine (P/RPT) 3HR= three months of daily isoniazid (H/INH) and rifampicin (R/RIF)
In Mexico City, the main cause of mortality among people living with HIV (PLHIV) continues to be opportunistic infections (OIs). Early detection of OIs allows their timely treatment and improves their prognosis. The use of rapid diagnostic tests (RDT) based on antigens of the most frequent causative agents of OIs allows adequate screening of these patients and facilitates decision making at the point of care. Unfortunately, these studies are not widely available in the different PLHIV care centers in the CDMX. We will conduct an open-label, non-inferiority uncontrolled clinical trial to investigate the diagnostic performance of urinary lipoarabinomannan, urinary Histoplasma antigen and serum Cryptococcus antigen in patients presenting for care with advanced HIV in CDMX, supported by rapid cluster of differentiation 4 (CD4) testing with lateral flow technology. Four referral hospitals will participate over 12 months. All patients with diagnosed HIV disease and suspected advanced disease presenting for care at participating centers will be included in the study. An inventory of approximately 1000 RDT will be obtained and distributed among the participating sites. A study coordinator will be hired and will visit each site once a week to collect the study variables and follow up on the included patients. The primary outcome of the study will be the percentage of patients with advanced disease who present with diagnoses made by RDT compared to historical controls of patients diagnosed with OI in 2022 at participating centers by conventional methods. Secondary outcomes will be time to initiation of antiretroviral therapy (ART), time to initiation of OI treatment, and 30-day mortality after HIV diagnosis.
