Drug resistance mutation analysis of HIV-1 among blood donors in Dalian:2011-2020
摘要
Abstract
Objective To study the distribution and trend of HIV-1 drug resistance mutation in Dalian blood donors be-tween 2011 and 2020.Methods The protease-reverse transcriptase(PR-RT)region was sequenced in Dalian blood donors tested HIV-1 positive between 2011 and 2020.Drug resistance mutation(DRM)rate and level of resistance to selected drugs were analyzed by the Stanford HIV Drug Resistance Database.Results DRM were detected in 17.2%(30/174)of samples,while transmitted drug resistance(TDR)was5.7%(10/174).Between2011 and2020,DRM and TDR rates in-creased significantly in 2019 and reached their highest levels in 2020(44.4%and 22.2%,respectively).DRM carriage was associated with people with college degree or above and with local residents(P<0.05).NNRTI DRMs were the most fre-quently detected(12.6%,22/174),followed by PIs(5.7%,10/174),with V179D/E/T and M46I being the main DRMs detected.Only one HIV-1strain(0.57%,1/174)carried a NRTI DRM(L74I).The overall rate of predicted high level re-sistance to antiretroviral drugs was 6.9%(12/174),with the highest proportion of NNRTI resistance(83.3%,10/12).Two samples were classified as highly resistant to EFV and NVP,accounting for 1.1%(2/174).CRF55_01B strains showed a significantly higher DRM rate than strains of other HIV-1 genotypes(P<0.05).Conclusion Between 2011 and 2020,the rate of HIV-1 DRMs in blood donors in Dalian showed a significant upward trend,particularly in 2019-2020,with NNRTI resistance being the most common.The combination of DRMs detection before and after implementation of ART un-der the latest national ART treatment plan would improve the effectiveness of HIV-1 prevention and control locally.关键词
