Brief Summary
The investigators' objective is to describe the variability of rifampicin absorption, markers of inflammation and gut damage, intestinal absorptive capacity, and intestinal permeability among HIV-infe...
Detailed Description
The dosing scheme for rifampicin for the treatment of tuberculosis was developed in the pre-HIV era, and achieving target concentrations at the site of infection is important for a successful outcome....
