Study Description

Brief Summary:

The purpose of this study is to see if the findings of increased lactic acid and abnormal fat distribution get better when d4T is replaced with abacavir, abacavir plus lamivudine, or Combivir (a pill containing lamivudine plus zidovudine) in HIV-positive patients taking anti-HIV therapy including stavudine (d4T).

Condition or disease	Intervention/treatment	Phase
HIV Infections Lipodystrophy	Drug: Lamivudine/Zidovudine Drug: Abacavir sulfate Drug: Lamivudine	Phase 4

Detailed Description:

Patients are allocated as follows: a) zidovudine-naive patients switch Combivir for d4t and b) zidovudine-experienced or -intolerant patients switch abacavir for d4t. Providers may choose between Combivir or abacavir as a switch for d4t when screening lactate levels are 2.2 mmol/L or more. Additionally, providers may choose to switch a maximum of 2 drugs, one of which must be d4t, in the regimen. Each patient receives 48 weeks of therapy. Visits are made at Weeks 2, 4, 8, 12, 16, 20, 24, 32, 40, and 48. Tests, including biopsies, are performed to measure changes in body fat distribution and changes in lactate levels. Virologic and immunologic outcomes, changes in physical signs of lipodystrophy, changes in self-reports of health-related quality-of-life survey and the Body Image Questionnaire, changes in lipid profile and other markers of metabolism, and safety parameters are evaluated also.
