简要总结
People with HIV have a high chance of becoming infected with TB, especially when they live in areas where TB infection is common. It can be difficult to diagnose TB in people who need to start HIV treatment right away. Within about 6 months after starting HIV treatment, some of these people can become very sick with TB and can even die from it.
This study was being done in people who were starting HIV treatment and who lived in areas where the TB infection rate is high. The purpose of this study was to test an experimental approach to TB treatment to see if it is better than the usual approach. The experimental approach was to start TB treatment at the same time as HIV treatment, even when TB infection had not been found. The usual approach was to start TB treatment only if TB infection was found.
In this study, half of the people started TB treatment at the same time as they started their HIV treatment. The other half started TB treatment only if TB infection was found.
The study also tested how safe and effective it was to start TB treatment at about the same time as HIV treatment even when TB infection had not been found. The study collected information about diet, whether (and when) people in the study became sicker or died, how well their HIV was controlled, how they were feeling, how they were taking their medications, whether it mattered where they lived or what kind of HIV and TB care was standard, how many people were diagnosed with TB while in the study, and how the cost of the two treatment options on a national level could be compared.
详细描述
This was a randomized, open-label, phase IV strategy trial for participants from resource-limited settings (RLS) who presented with advanced HIV disease and no probable or confirmed tuberculosis (TB), and who were initiating antiretroviral treatment (ART).
Participants were randomized to one of two strategy arms: immediate, empiric TB treatment (Empiric arm) or local standard of care TB treatment (IPT arm).
Randomization was balanced by clinical trial unit and stratified according to CD4+ T cell count (<25 vs. ≥25 cells/mm^3) and presence of any of the following prognostic factors: reportable hospitalization within the past 30 days, BMI <18.5 kg/m^2, or anemia (hemoglobin <8 g/dl).
Participants were followed for 96 weeks. Participants attended study visits at screening, enrollment, and weeks 1, 2, 4, 8, 12, 16, 20, 24 and 48. Signs and symptoms, ART modifications, concomitant medications, and clinical events as defined by AIDS Clinical Trials Group (ACTG) Appendix 60 were collected at each visit. Blood was collected for CD4 and HIV-1 RNA at study entry, weeks 4, 24 and 48, and blood for safety laboratories (liver function, hematology, and renal function) was collected at all visits except week 1. A sputum sample was collected and stored at study entry. Phone contact was conducted at weeks 60, 72, 84 and 96 to obtain information about vital status, reportable hospitalization, TB status (including screening and follow-up), TB and HIV treatment modifications, and quality of life.
