DEPIVIH 2: Use of three HIV testing methods in French primary care settings - ELISA laboratory screening versus two rapid point-of-care HIV tests

Isothermal nucleic acid amplification technology in HIV detection

Nucleic acid testing for HIV plays an important role in the early diagnosis and monitoring of antiretroviral therapy outcomes in HIV patients and HIV-infected infants. Currently, the main molecular diagnostic methods employed are complex, time-consuming, and expensive to operate in resource-limited areas. Isothermal nucleic acid amplification technology overcomes some of the shortcomings of traditional assays and makes it possible to use point-of-care tests for molecular HIV detection. Here, we summarize and discuss the latest technological advances in isothermal nucleic acid amplification for HIV detection, with the intent of providing guidance for the development of subsequent HIV assays with high sensitivity and specificity.

HIV Testing Strategies, Types of Tests, and Uptake by Men Who have Sex with Men and Transgender Women: A Systematic Review and Meta-analysis

This systematic review and meta-analysis investigated the effectiveness of strategies and types of tests on HIV testing uptake by men who have sex with men (MSM) and transgender women (TGW), and in reaching PLWH. Articles published up to July 2020 were identified from major electronic databases and grey literature. Data were extracted and assessed for risk of bias. Estimates were pooled using random-effect meta-analysis while heterogeneity was evaluated by Cochran's Q test and I². This study is registered with PROSPERO (CRD42020192740). Of 6820 titles, 263 studies (n = 67,288 participants) were included. The testing strategies reported in most studies were community- (71.2%) and facility-based (28.8%). Highest uptake, with facility-based testing, occurred and reached more PLWH while with standard laboratory tests, it occurred with the highest HIV prevalence among MSM. However, urine test showed a highest rate of new HIV infection. Multiple test combinations had the highest uptake and reached more PLWH among TGW. Various testing strategies, considering barriers and regional differences, and different test types, need be considered, to increase uptake among MSM and TGW.

Exploring sexualized substance use, sexual behaviors and HIV-screening practices in people attending erotic industry shows

Previous studies showed that Erotic industry sShows (ES) were appropriate events for sexual health promotion and testing interventions. A cross-sectional survey exploring screening practices, sexual behaviors, substance use, and sexual motives for substance use was conducted in ES in December 2017 and completed by 781 respondents. Overall, . Eighteen18% percent reported substance use in the last 3 months (51% alcohol), 26%. Twenty-six percent reported a sexual purpose for substance use. Main sexual partners were spouse (68%), regular (21%), unknown (18%) and several (17%) partners. Main sexual practices were libertinism (22%), partner swapping (15%) and threesome (15%). Twenty-seven percent of respondents reported cContactless sex was reported by 27% of the respondents. 18% reported no previous HIV test. Univariate analysis showed that having or not previous HIV test was linked to male sex (76.8% vs. 54.5%, p < 10-3), alcohol consumption in the last three months (58.7% vs. 49.4%, p = .043), number of drugs in a lifetime (1.3% vs. 1.6%, p = .022), sexual partnership with spouse/long-term partner (57.3% vs. 70.5%; p = .002), at least one multiple-partner sexual practice (23.1% vs. 31.8%, p = .040) and type of sexual attraction (p = <10-3). Results contribute to establishing the usefulness of HIV-testing and awareness campaigns in ES eventsand informing potential combined risk behaviors and related interventions.

Sexual risk factors related to lack of HIV-screening in people attending erotic industry shows

The current aim of the fight against the HIV epidemic is to reduce the proportion of missed opportunities for HIV diagnosis. Erotic industry Shows (ES) were deemed to be appropriate events to organize awareness campaigns and to propose HIV Rapid Diagnostic Test (HIV-RDT) to people who are sexually active and likely to engage in unsafe sex practices. In 2015, a cross-sectional study in 4 ES was conducted to document the sexual risk factors associated with HIV-screening test approach and the proportion of positive HIV-RDT. Prevention booths were set up to offer HIV-screening to individuals ≥18 years volunteers for HIV-RDT and to respond to a validated anonymous self-reported questionnaire. In 4 ES, 943 participants were questioned and tested, mainly men (64%), young (mean age 30 years old), living as a couple (63.7%). A large majority (95.1%) reported sexual intercourse over the last year. The mean number of partners was 4.8. About 2/3 had unprotected sex. 37.5% had never been tested and had their first test during this campaign. The 430 participants who reported no previous HIV-testing during the last 5 years more frequently declared heterosexual intercourse (OR: 2.31), identifying as a male (OR: 1.82), having transactional sex (OR: 1.92), living as a couple (OR: 1.67), having fewer sexual partners (OR: 1.06) and being younger (OR = 1.02). Three people (0.32%) were tested positive for the HIV-RDT; linkage with care was ensured for confirmatory test. This innovative and original intervention showed for the first time the usefulness of HIV-screening and awareness campaigns, in fun and commercial backdrop event. Individuals who had never been HIV-tested and who had no intention of doing so before this campaign were reached and engaged. ES are potential new locations to get HIV information and screening, to tackle sexual health-related issues and reflect on sexual risk behaviors.
