Abstract
INTRODUCTION: Since the development of antiretroviral therapy (ART) with TDF plus 3TC plus EFV, this specific regimen has not been studied enough with long-term lipid and uric acid monitoring. METHODS: A prospective follow-up cohort study was performed. Sixty-one treatment-naive male patients with human immunodeficiency virus (HIV) were divided into three groups based on their baseline CD4+ cell count (26, 12, and 23 patients in the < 200, 200 to 350, and > 350 groups, respectively). The lipid and purine metabolism parameters of the patients over 144 weeks were analyzed. RESULT: Within 144 weeks, TG, LDL-c, TC and HDL-c gradually increased, especially TC and HDL-c (P = 0.001, 0.000, respectively). Moreover, the percentages of hyper-cholesterolemia, hyper LDL cholesterolemia, hyper-triglyceridemia and low HDL cholesterolemia also gradually increased, especially low HDL cholesterolemia significantly increased (P = 0.0007). The lower the baseline CD4+ cell counts were, the higher the TG levels and the lower the TC, LDL-c and HDL-c levels were. But there was significant difference of only baseline LDL-c levels between the three groups (P = 0.0457). No significant difference of the UA level and the percentages of hyperuricemia was found between the different follow-up time point groups or between the three CD4+ cell counts groups (all P > 0.05). The risk factors for dyslipidemia included age, anthropometric parameters and follow-up weeks, and for hyperuricemia was virus load. CONCLUSIONS: Gradual increasing dyslipidemia was found in male patients with human immunodeficiency virus primarily treated with tenofovir plus lamivudine plus efavirenz for 3 years. There-fore lipid metabolism parameters should be closely monitored during long-term ART with the TDF plus 3TC plus EFV regimen.
