Abstract PURPOSE: To describe the clinical features in HIV-1-infected patients treated with protease inhibitors (PIs) or not, and to determine factors related to occurrence of lipodystrophy (LD). METHOD: We performed a cross-sectional analysis of 685 treated HIV-1-infected patients that were routinely followed in 6 Paris hospital centers between January and May 1999. Demographic data, familial and personal vascular risk factors, history of antiretroviral treatment, HIV plasma viral load, CD4 cell count, and metabolic data were collected. Clinical examination was based on an assessment of changes in abdominal, dorso-cervical, and breast girth and wasting of the limbs, face, and skin as quoted by the clinician. RESULTS: The mean age at inclusion in the study was 38 years; 29.5\% were women. At study assessment, 77.5\% of patients were PI-treated and 22.5\% had never received a PI. LD was observed in 403 (58.8\%) patients, of whom 340 were currently receiving a PI and 63 had never received a PI. More than half of the lipodystrophic patients had a mixed form (53.9\%), while 25.3\% were classified as exclusive lipoatrophic and 20.8\% as exclusive hypertrophic. In multivariate analysis, older age, duration of antiretroviral treatment (ART), antiretroviral combinations including stavudine, antiretroviral combinations including a PI, AIDS status, and a low HIV RNA were independently associated with occurrence of LD. CONCLUSION: LD is frequently observed in PI-treated patients, but it is also observed in patients receiving an ART regimen without PIs. Our study suggests different underlying mechanisms, because immunovirological response to treatment as well as certain therapies were linked to the occurrence of LD. This hypothesis would be best clarified in a large prospective cohort of naive patients.
