Clinical and biochemical evaluation of HIV-related lipodystrophy in an ambulatory population from the Hospital Universitário Cassiano Antonio de Morais, Vitória, ES, Brazil.

We designed a retrospective cohort study to identify factors associated with HIV-1 related lipodystrophy at a tertiary HIV-care center in Vitória, ES, Brazil. Inclusion criteria were documented HIV diagnosis, anti-retroviral therapy and age above 17 years. Highly active antiretroviral therapy (HAART) was initially the exposure variable, but a second analysis was also performed, as a nested case-control, based on the presence or absence of lipodystrophy. Use of protease inhibitors (PI) was associated with an increase in serum triglycerides (243.7 ± 189 mg/dL vs. 172.7 ± 131 mg/dL, p = 0.015), but not of total cholesterol (TC) or HDL fraction levels. Non-nucleoside reverse transcriptase inhibitors (NNRTI) were associated with an increase in serum TC (180.6 ± 46.8 mg/dL versus 162.4 ± 41.4 mg/dL; p= 0.018) and an increase in HDL cholesterol (47.3 ± 13.8 mg/dL versus 23.3 ± 24.3 mg/dL; p < 0.001), with no significant effect on triglyceride levels. Lipodystrophy was diagnosed in 59.3% of the patients, but exposure to PI versus NNRTI did not affect the frequency of this disorder (43.4% versus 37.2%; p = 0.68). Serum TC, but not HDL cholesterol or triglyceride levels, was higher among the lipodystrophy cases (183.8 ±47.5 mg/dL versus 162.1 ±35.7; p=0.006). Among the controls (patients without lipodystrophy), HDL cholesterol (45.3 ±14.4 mg/dL vs. 27.1 ±26.3; p=0.001)and triglyceride levels (178.3 ±146.3 mg/dL vs. 126.3 ±126.9; p=0.013) also increased, but not TC. In conclusion, lipodystrophy was highly prevalent in our series. Lipid disorders were also frequent and apparently were related to lipodystrophy, except for triglyceride levels.
