ABSTRACT
Objective@#To understand the distribution of HIV-1 genotypes and the status of drug resistance among people living with HIV who had prepared to initiate antiretroviral therapy (ART) in Dehong Dai and Jingpo autonomous prefecture (Dehong).@*Methods@#A total of 170 adults with HIV were recruited in Dehong from January to June 2017, before initiating ART. HIV-1 pol genes were amplified and used to analyze the HIV-1 genotypes and drug resistance.@*Results@#A total of 147 samples were successfully sequenced. Based on the phylogenetic analysis, 12 HIV-1 genotypes were found among the subjects, including three predominant genotypes such as subtype C (29.9%, 44/147), unique recombinant forms (URFs) (27.2%, 40/147) and CRF01_AE (19.7%, 29/147). Circulating recombinant forms (CRFs) which were newly identified in this area in recent years were also found among these subjects, including CRF62_BC, CRF64_BC, CRF86_BC and CRF96_cpx. The distribution of HIV-1 genotypes between heterosexual transmission or intravenous drug use, showed statistical difference. Surveillance drug resistance mutations (SDRMs) were found among 8.8% (13/147) of the subjects. Proportion of drug resistant strains among injecting drug users (25.0%, 8/32) was higher than that among those heterosexual transmitted individuals (4.6%, 5/109, χ2=10.166, P=0.002).@*Conclusions@#Among people living with HIV-1 who had prepared to initiate ART, their HIV-1 genetics were highly complicated, with moderate prevalence rate of HIV-1 drug-resistant strains.
