摘要

Pharmacogenetics refers to the effect of single nucleotide polymorphisms(SNPs)within human genes on drug therapy outcome.Its study might help clinicians to increase the efficacy of antiretroviral drugs by improving their pharmacokinetics and pharmacodynamics and by decreasing their side effects.HLAB*5701 genotyping to avoid the abacavir-associated hypersensitivity reaction(HSR)is a cost-effective diagnostic tool,with a 100%of negative predictive value,and,therefore,it has been included in the guidelines for treatment of human immunodeficiency virus(HIV)infection.HALDRB*0101 associates with nevirapine-induced HSR.CYP2B6 SNPs modify efavirenz plasma levels and their genotyping help decreasing its central nervous system,hepatic and HSR toxicities.Cytokines SNPs might influence the development of drug-associated lipodystrophy.APOA5,APOB,APOC3 and APOE SNPs modify lipids plasma levels and might influence the coronary artery disease risk of HIV-infected individuals receiving antiretroviral therapy.UGT1A1*28 and ABCB1(MDR1)3435C>T SNPs modify atazanavir plasma levels and enhance hyperbilirubinemia.Much more effort needs to be still devoted to complete large prospective studies with multiple SNPs genotyping in order to reveal more clues about the role played by host genetics in antiretroviral drug efficacy and toxicity.
