简要总结
The purpose of this study is to compare the body fat distribution in Human Immunodeficiency Virus-1 (HIV-1) infected patients receiving, since the beginning and for at least two years, an antiretroviral therapy based on efavirenz or lopinavir/ritonavir and a combination of tenofovir plus emtricitabine (or lamivudine).
详细描述
Lipodystrophy (also called abnormal fat redistribution) associated with HIV infection is characterized by loss of subcutaneous adipose tissue (lipoatrophy) that is more apparent in the limbs, face, and buttocks, or by accumulation of adipose tissue (lipohypertrophy) in the intra-abdominal cavity, the mid, upper back, and breasts. Lipodystrophy may also occur in a mixed form (lipoatrophy and lipohypertrophy in the same patient).
Participants made a single study visit. Dual energy X-ray absorptiometry (DEXA) was performed within 30 days of this study visit. In addition, routine visit clinical results, demographic data, disease data, comorbidities and concomitant medications were collected.

结局指标
主要结局
Total Limb Fat Mass
时间窗: Study visit
Total limb fat mass was assessed by dual energy X-ray absorptiometry (DEXA) scan. DEXA uses a whole body scanner and two different low-dose x-rays to read bone mass and soft tissue mass.
次要结局
- Distribution of Body Fat Mass(Study visit)
- Lipodystrophy Severity Grading Scale (LSGS) Scores(Study visit)
- Change Over Time in Body Fat Distribution(DEXA performed at the study visit and more than 6 months prior to the study visit (the period of time between the DEXA recorded at the study visit and the previous DEXA ranged from 6 to 36 months).)
