Abstract
Abstract: Tuberculosis (TB) is one of the most common opportunistic infections among persons with HIV infection. However, there are uncertainties about both TB and HIV treatment regimens among patients with advanced immunodeficiency. On the TB treatment side, there are lingering concerns about whether patients with advanced immunodeficiency should have a more intensive regimen for TB treatment (longer duration, more frequent [daily] dosing and/or post‐treatment isoniazid). The use of antiretroviral therapy among patients with TB and AIDS dramatically decreases the risk of death and other opportunistic infections. However, use of antiretroviral therapy during TB treatment is complicated by the need to coordinate the activities of the TB control program and the HIV care clinic, overlapping side‐effect profiles of anti‐TB and antiretroviral drugs, drug–drug interactions between the rifamycins and many antiretroviral drugs, and the occurrence of immune reconstitution inflammatory syndrome events. The combination of rifampin‐based TB treatment and efavirenz‐based antiretroviral therapy is clearly the best option for cotreatment of these two infections. However, there are a number of uncertainties about the optimal antiretroviral therapy if efavirenz cannot be used (because of intolerance, drug resistance, pregnancy or lack of an appropriate formulation in children). The competing risks of AIDS events and severe immune reconstitution inflammatory syndrome events raise uncertainties about the optimal timing of antiretroviral therapy during TB treatment. Despite all of these complexities, the treatment of HIV‐related TB can be remarkably successful. I review these unresolved questions in the treatment of HIV‐related TB and suggest studies to help resolve them.
