Abstract:Objective To analyze the rate and influencing factors of virologic failure of antiretroviral therapy (HAART) lasting more than 6 months for HIV/AIDS in Nanchang City during 2015-2021, and to provide references for comprehensive assessment and timely intervention. Methods A retrospective analysis method was used to collect the data related to HAART from the National Information System for HIV/AIDS Comprehensive Prevention and Control, China Information System for Disease Control and Prevention and designated hospitals in Nanchang City, and the factors influencing virologic failure in patients with HAART were analyzed. Results A total of 1,690 patients with HIV/AIDS were enrolled in the study, with a virologic failure rate of 5.76/100 person-years. The results of multivariate logistic regression analysis indicated that injecting drug use/transmission by blood transfusion (aOR=9.66, 95%CI:2.00-46.61), HAART lasting time < 1 year (aOR=2.49, 95%CI:1.01-6.09), recent CD4+T-lymphocyte cell counts < 200 cells/μl (aOR=12.59, 95%CI:6.45-24.62) and recent CD4+T-lymphocyte cell counts ranged 200-500 cells/μl (aOR=2.52, 95%CI:1.32-4.79), the initial HAART regimen “AZT+3TC+EFV/NVP” (aOR=2.54, 95%CI:1.27-5.06), missed taking antiviral medication in the last 7 days (aOR=7.99, 95%CI:3.88-16.45), HIV/AIDS and hepatitis C virus co-infection (aOR=4.86, 95%CI:1.81-13.03), positive drug resistance test (aOR=4.09, 95%CI:1.85-9.04) were factors affecting virologic failure in the HIV/AIDS patients with HAART. Conclusion Under the current HAART strategy, it is necessary to pay special attention to the mode of transmission for HIV/AIDS, lasting time of HAART, self-immune level, missed taking antiviral medication, HIV/AIDS and hepatitis C virus co-infection and drug resistance, and conduct comprehensive evaluation and timely intervention so as to reduce adverse outcomes due to late identification of virologic failure.
