The efficacy and safety of a combination regimen including either efavirenz or lopinavir-ritonavir was examined in a cohort of 65 patients positive for human immunodeficiency virus-1 (HIV-1). Both the efavirenz (n = 33, 18 anti-retroviral naive) and lopinavir-ritonavir (n = 32, 15 naive) regimens achieved significant changes from baseline CD4 cell counts and HIV RNA levels after 108 weeks (p < 0.01). Despite diminished immunological and virological parameters at study entry, the lopinavir-ritonavir group showed greater virological effects than the efavirenz group after 108 weeks (median change 3.3 log(10), interquartile range (IQR) 2.2-3.8 log(10) vs. 2.4 log(10), IQR 0.9-3.3 log(10), respectively, p 0.004). Use of lopinavir-ritonavir, in contrast to use of efavirenz, was associated with significant hypertriglyceridaemia.
