Effects of Treatment Changes on Fat Wasting in the Arms and Legs of HIV Patients

Summary

The goals of this study are to find out if fat wasting and weight loss in the arms and legs of HIV patients taking highly active antiretroviral therapy (HAART) are caused by nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) and if wasting can be reversed if the NRTI is stopped and replaced with other anti-HIV drugs.
