IntroductionSince the start of highly active antiretroviral therapy (HAART) with TDF plus 3TC plus EFV, the long-term dynamic characteristics of lipid and purine metabolism in patients infected with human immunodeficiency virus (HIV) was unclear and worth studying.MethodsA prospective follow-up cohort study was the way. Sixty-one treatment-naive HIV infected male patients were divided into three groups based on the baseline CD4 + T cell count (26, 12, 23cases in < 200, from 200 to 350, > 350 three groups, respectively). Lipid and purine metabolism parameters of those patients within 144 weeks were analyzed.ResultTG, TC, LDL-c and HDL-c level all gradually increased within 144 weeks, but statistical significances of TC level and HDL-c level were only found (F = 4.214, 5.518, P = 0.001, 0.000 ,respectively). Moreover the percentage of hypercholesterolemia, hyper LDL cholesterolemia and hypertriglyceridemia all gradually increased, low HDL cholesterolemia gradually decreased, but there was only obvious difference of the latter (χ2 = 16.105, P = 0.0007).Furthermore the lower the baseline CD4 + T lymphocyte counts, the higher TG level, the lower TC level, LDL-c level and HDL-c level, but only significant difference of LDL-c level between three groups at baseline was found (F = 3.256,P = 0.0457).Although UA level and the percentages of hyperuricemia gradually increased within 144 weeks, but there was no significant difference between different follow-up time points groups and between three CD4 + T cell count groups (all P༞0.05).ConclusionsThese findings provide a reference for clinicians to monitor lipid metabolism parameters closely during long-term HAART with TDF plus 3TC plus EFV regimen.
