BackgroundData on lipid profile derangements induced by antiretroviral treatment in Africa are scarce. The aim of this study was to determine the prevalence and characteristics of lipid profile derangements associated with first-line highly active antiretroviral therapy (ART) among Cameroonians living with human immunodeficiency virus (HIV) infection.MethodsThis cross-sectional study was conducted between November 2009 and January 2010, and involved 138 HIV patients who had never received ART (ART-naive group) and 138 others treated for at least 12 months with first line triple ART regimens that included nevirapine or efavirenz (ART group). Lipid profile was determined after overnight fast and dyslipidemia diagnosed according to the US National Cholesterol Education Program III criteria. Data comparison used chi-square test, Student t-test and logistic regressions.ResultsThe prevalence of total cholesterol ≥ 200 mg/dl was 37.6% and 24.6% respectively in ART group and ART-naive groups (p = 0.019). The equivalents for LDL-cholesterol ≥ 130 mg/dl were 46.4% and 21% (p ≤ 0.001). Proportions of patients with total cholesterol/HDL-cholesterol ratio ≥ 5 was 35.5% in ART group and 18.6% in ART-naive group (p ≤ 0.001). The distribution of HDL-cholesterol and triglycerides was similar between the two groups. In multivariable analysis adjusted for age, sex, body mass index, CD4 count and co-infection with tuberculosis, being on ART was significantly and positively associated with raised total cholesterol, LDL-cholesterol and TC/HDL cholesterol. The adjusted odd ratios (95% confidence interval, p-value) ART-treated vs. ART-naïve was 1.82 (1.06-1.12, p = 0.02) for TC ≥ 200 mg/dl; 2.99 (1.74-5.15), p < 0.0001) for LDL-cholesterol ≥ 130 mg/dl and 1.73 (1.04-2.89, p = 0.03) for TC/HDL-cholesterol ≥ 5.ConclusionsFirst-line antiretroviral therapy that includes nonnucleoside reverse transcriptase inhibitors is associated with pro-atherogenic adverse lipid profile in people with HIV-1 infection compared to untreated HIV-infected subjects in Yaounde. Lipid profile and other cardiovascular risk factors should be monitored in patients on such therapy so that any untoward effects of treatments can be optimally managed.
ObjectivesLipid abnormalities associated with antiretroviral therapy in people with HIV infection are more frequent with protease inhibitors (PI)-based regimens. Whether effects extend to patients receiving a PI subsequent to failure on non-nucleoside reverse-transcriptase inhibitors (NNRTI)-based regimen is still unknown. We investigated the effects of secondary treatment with a PI on the lipid profile in a group of patients with HIV infection in Cameroon.DesignThis was a cross-sectional study.SettingThis study was carried out at the registered centre for HIV treatment of the Yaounde Jamot Hospital in Cameroon.ParticipantsParticipants were consecutively recruited between November 2009 and January 2010. There were 138 HIV-1 patients on initial treatment with an NNRTI regimen and 66 HIV patients on secondary treatment with a PI for at least 12 months. Lipid abnormalities were based on the National Cholesterol Education Program, Adult Treatment Panel III criteria.Outcome measuresLevels of lipid parameters among patients on PI and NNRTI.ResultsMedian (IQR) levels (mg/dl), NNRTI-treated versus PI-treated patients were 185 (149–225) and 189 (147–244) for total cholesterol, 46 (27–66) and 42 (28–82) for high-density lipoprotein (HDL)-cholesterol, 121 (90–169) and 126.9 (71–176) for low-density lipoprotein (LDL)-cholesterol, 134 (98–174) and 138 (111–167) for triglycerides, and 4.3 (2.9–6.2) and 5.1 (2.6–7.9) for total/HDL-cholesterol ratio (all p>0.32). The most frequent lipid abnormality in the two groups was high LDL-cholesterol (46.4% (NNRTI) vs 54.5% (PI)). The occurrence of lipid abnormalities was similar in the two groups (all p>0.29).ConclusionsThe use of PI does not appear to deteriorate the lipid profile of HIV patients above and beyond abnormalities induced by an unsuccessful initial treatment with NNRTI. Monitoring of lipid profile during HIV treatment regardless of the regimens would improve timely detection and management of abnormalities, to mitigate related risks.
