Filter by:Open-label, two-arm, randomized multicenter study to investigate the safety, tolerability, and pharmacokinetics (PK), and potential interactions between dolutegravir (DTG) and rifapentine (RPT) during pregnancy in people with HIV when RPT is given with isoniazid (INH) daily for 4 weeks (1HP) or weekly for 3 months (3HP) as part of tuberculosis (TB) preventive therapy (TPT). Adults (age ≥18) who are pregnant with a singleton pregnancy (confirmed by ultrasound) at a gestational age of 20-34 weeks and virally suppressed on an existing DTG-based plus two nucleoside reverse transcriptase inhibitors (NRTI) antiretroviral (ART) regimen for at least four weeks may participate.
A multicenter, randomized, stratified, open-label, phase IV trial among HIV-positive persons (PLHIV) on antiretroviral therapy (ART), or HIV-negative household contacts of patients with rifampicin-sensitive pulmonary tuberculosis (TB), who do not have evidence of active TB.
This hybrid type I effectiveness-implementation trial will increase understanding of the effectiveness and cost-effectiveness of integrating a brief evidence-based treatment for major depressive disorder (MDD) within the tuberculosis (TB) care platform to improve TB and MDD. Findings from this R01 are likely to inform policy and treatment guidelines for the integrated management of TB and MDD in low- and middle-income countries globally.
The purpose of this study is to assess the efficacy and safety of a molecular drug-sensitivity test-guided individualized shorter all-oral regimen composed of 4-5 anti-tuberculosis drugs recommended by WHO in RRTB patients for 9-12 months in real-world practice, in some high RR-TB burden province of China. This study hopes to form a clinical pathway of all oral short-term treatment based on the guidance of rapid molecular drug sensitivity that can be popularized in China, and update the Chinese guidelines of RR-TB treatment management.
Two commonly used treatments for latent tuberculosis infection are either 4 months rifampicin or 6-9 months isoniazid. The invistigators will study the risk of acquisition of rifampicin resistance in commensal Staphylococcus aureus in persons treated with rifampicin versus in persons treated with isoniazide. Through repeated swab cultures before, during, and after treatment the investigators will also investigate potential accumulation of mutations associated with rifampicin resistance over time. Finally, household contacts to persons with rifampicin-resistant S. aureus will be examined to investigate whether onward transmission of rifampicin-resistant S. aureus occurs within households.
Tuberculosis (TB) is the leading cause of death among children with HIV, yet insufficient data are available on the pharmacokinetics of newer HIV/TB cotreatment strategies in children. Current WHO-recommended rifampicin dosages result in low concentrations in most children, and high-dose rifampicin may improve outcomes and shorten treatment duration. Yet the impact of high-dose rifampicin on dolutegravir exposures has not been examined in children. This study aims to evaluate the safety and pharmacokinetics of dolutegravir twice daily among HIV/TB coinfected children receiving standard-dose and high-dose rifampicin.
Stool4TB aims to evaluate an innovative stool-based qPCR diagnostic platform (with the capacity to become a POC diagnostic tool) in the high TB and HIV burden settings of Mozambique, Eswatini and Uganda, under the hypothesis that it will narrow the extremely large TB case detection gap by improving TB confirmation rates in children and people living with HIV (PLHIV).
To improve accurate diagnosis and treatment of common malignant tumors and major infectious diseases in the respiratory system, we aim to establish a large medical database that includes standardized and structured clinical diagnosis and treatment information such as electronic medical records, image features, pathological features, and multi-omics information, and to develop a multi-modal data fusion-based technology system for individualized intelligent pathological diagnosis and therapeutic effect prediction using artificial intelligence technology.
This study pretends to evaluate the potential use of Hyfe Cough Tracker (Hyfe) to screen for, diagnose, and support the clinical management of patients with respiratory diseases, while enriching a dataset of disease-specific annotated coughs, for further refinement of similar systems.
Background: Tuberculosis (TB) is a lung disease. It is caused by inhaling a type of airborne bacterium. Tuberculin Purified Protein Derivative (PPD) is used to test for TB exposure. It is usually injected under a person s skin. In this study, it will be applied in the lung. Objective: To learn how the cells within the lung react (immune response) when exposed to PPD. Eligibility: Adults ages 18-64 who (1) have been exposed to TB but do not have active disease or symptoms or (2) have never been exposed to TB. Design: Participants will be screened with a medical history, physical exam, and blood tests. They will have a TB skin test. They will also have an electrocardiogram to examine heart rhythm. For this, sticky patches will be placed on their chest. Some screening tests will be repeated at study visits. Participants will have 3 FDG PET-CT scans. They will lie in a machine that creates pictures of the inside of their body. They will get a radioactive substance injected into their arm called 18FDG. It helps make the pictures. Participants will have 3 bronchoscopies. Their mouth and nasal airways will be numbed. They will get drugs to relax. A tube will be inserted through their nose or mouth into a lung. Fluid will be delivered into the lung and suctioned back out to collect cells. They will get PPD during the first bronchoscopy. Participation will last for about 30 days. Participants will visit the clinic up to 8 times. They will go home after each procedure. No hospital stays are needed.
