RESUMO
At present, China's AIDS testing increased rapidly, but there are still many people living with HIV do not recognize their status, thus postponing the antiviral treatment time. HIV self-testing (HST) is an effective method to expand the testing, not only simple operation, easy to get a result, effectively protect the detection privacy, expand the selection of testers, suit to the entire population, but also the premise and basis of other AIDS comprehensive prevention measures, all over the world are promoting it. Because the HST has controversies in the window period, price and before and after controversial, and our country is in the initial stage of HST, so it is not to develop related policies, but more and more countries are in accordance with their own situations are modified or developed to allow to use rapid detection of AIDS policy to regulate the field. This paper analyzed and summarized the advantage and influence factors of HST promotion, HST believes that in the long term, the advantages outweigh the disadvantages, we need to formulate relevant policies, and improve the sensitivity of the kit, shorten the window period of time, production and promotion of operation standard of video, specification and testing the operating practices, preventing and reporting the possible social harm, investigation and understanding of the needs of the people of the crowd, to maximize the advantages of HST, find more infection, so as to curb the epidemic of AIDS.
RESUMO
Objective@#To understand the incidence and related factors of HIV-1 drug resistance among HIV/AIDS patients experiencing treatment failure in Jiangsu province, China.@*Methods@#The HIV/AIDS integrated prevention and control data information management system of China were used to collect the basic data of patients, blood specimens were collected from patients who had antiretroviral therapy (ART) failure with ≥12 months and older than 18 years in 2016 in Jiangsu, excluding cases with missing information, 713 cases were enrolled in this study. HIV-1 RNA was extracted, and then pol gene region was amplified and sequenced. The obtain sequences were submitted to Stanford University HIV Drug Resistance Database to interpret and analyse HIV-1 drug resistance and sub-types. Multivariate logistic regression model was used to explore the related factors of drug resistance.@*Results@#A total of 579 subjects were amplified successfully, male accounted for 85.66% (496 cases), and the median age was 39 years old. The main route of infection was sexual transmission (553 cases, 95.51%). A total of 331 patients with drug resistance gene mutation were detected, drug resistance mutation rate was 57.18%. Compared with patients with baseline CD4+T cell count >500 cells/μl, patients with CD4+T cell count in 201-500 cells/mm3 and ≤200 cells/μl had a higher incidence of genetic drug resistance, the odds ratio was 3.33 and 6.87, respectively. Compared with patients with treatment less than 24 months, patients treated for 25-48 months had a higher incidence of drug resistance, the odds ratio was 1.88. Compared with patients infected by CRF07_BC strains, patients infected by CRF01_AE strains were associated with higher incidence of drug resistance, the odds ratio was 2.22 and 3.32, respectively. Protease inhibitor (PI) resistance mutations, nucleoside reverse transcriptase inhibitor (NRTI) and non-nucleoside reverse transcriptase inhibitor (NNRTI) were found in 3.80%, 33.16% and 53.37% of patients, respectively. 31.95% of patients harbored NRTI and NNRTI resistance mutations simultaneously. M184V/I and K103N/Q were the highest frequency of NRTI and NNRTI resistance mutation, the prevalence of M184V/I and K103N/Q were 28.15% and 22.28%, respectively.@*Conclusion@#The status of HIV-1 drug resistance mutations are complex and diverse among patients experiencing failure of ART in Jiangsu. Patients with lower baseline CD4+T cell count, longer treatment time and HIV-1 CRF01_AE and B strains infection were associated with higher incidence of drug resistance mutation.
