- Abstract
The aim of this exploratory study was to investigate in a homogeneous population of anti-retroviral naïve HIV-1-infected adults, the relationships between genetic polymorphisms involved in nevirapine metabolism [CYP2B6 516G>T, 785A>G and 1459C>T; CYP3A5 6986A>G (CYP3A5*3)], transport (ABCB1 2677G>T/A and 3435C>T), and antigen recognition (HLA-DRB1*0101), and the hepatic and/or cutaneous toxicity occurring within the first 8 or 72 weeks of treatment, plasma trough concentrations (C(trough) ) at week 8 and immuno-virological response to nevirapine at week 24. Associations between genetic polymorphisms and toxicity, C(trough) and response to nevirapine were performed in a population of 72 HIV-1 positive and nevirapine-treated patients followed during 72 weeks, as part of the previous study called: ANRS081 'Trianon' trial. Among the 18 patients who developed toxicity events during the 72 weeks of the study, 12 patients exhibited early toxicity before week 8. No significant association could be evidenced between any of the analysed single nucleotide polymorphisms (SNPs) and nevirapine early or global toxicity, pharmacokinetics and immuno-virological responses even though a possible association between CYP2B6 516G>T and 1459C>T and the trough level of nevirapine was suggested.
