Switching From Zidovudine to an NNRTI or Lopinavir/Ritonavir in Patients Treated With Zidovudine/ Lamivudine/Abacavir.

Phase 4

Completed

• Conditions: HIV Associated Lipodystrophy Syndrome.; HIV; Hypercholesterolemia; Lipoatrophy

• Registration Number: NCT00139178
• Lead Sponsor: Danish HIV Research Group

Brief Summary

Highly active antiretroviral therapy (HAART) has improved the long time survival of HIV infected individuals. However an increasing number of HIV-patients have developed metabolic and morphological alterations including peripheral lipoatrophy.

The main hypothesis of the study is that switching from thymidine-analogue based HAART will reverse lipoatrophy.

We plan to perform an observational study recruiting up to 100 HIV-infected patients receiving Trizivir (zidovudine/lamivudine/abacavir).

The patients will be offered an NRTI or lopinavir/ritonavir instead of zidovudine or they can choose to continue with Trizivir.

The main endpoint is changes in peripheral fat mass as determined by DEXA-scanning.
