Men who have sex with men (MSM) and Transgender Women (TGW) in Thailand contribute to more than half of all new HIV infections annually. This cross-sectional study describes epidemiologic profiles of these key populations (KP) in Key Population-led Test and Treat study. Baseline data were collected using self-administered questionnaires and HIV/STI testing from MSM and TGW aged ≥18 years enrolled in a cohort study in six community sites in Thailand between October 2015 and February 2016. Factors associated with HIV prevalence were determined by logistic regression. TGW in the cohorts had lower education and income levels than MSM. TGW also engaged in sex work more, though similar proportions between MSM and TGW reported to have multiple sexual partners and STI diagnosis at baseline. HIV prevalence was 15.0% for MSM and 8.8% for TGW in the cohorts. HIV prevalence among TGW was more associated with sociodemographic characteristics, whereas factors related to behavioral risks were determined to be associated with HIV prevalence among MSM. TGW and MSM in the cohorts also had high prevalence of STI. Key Population-driven HIV services are able to capture harder-to-reach key populations who are at heightened risk for HIV.

Background Based on government estimates from the Asian Epidemic Model, new infections among men who have sex with men (MSM) and transgender women (TGW) in Thailand are forecast to proportionally increase over time. Daily oral Pre-exposure prophylaxis (PrEP) protects against HIV acquisition when used as prescribed. The “Princess PrEP” program is the first key population-led (PrEP) initiative under Thai royal patronage with an aim to scale up countrywide implementation of PrEP. Methods Retention in and adherence to key population-led HIV PrEP services among HIV-uninfected Thai MSM and TGW was examined in four provinces: Bangkok, Chonburi, Chiang Mai, and Songkhla. HIV, HBsAg, creatinine tests, and self-administered questionnaires were performed during baseline measures. Participants were followed up after month 1, at month 3, then every 3 months. Correlates of nonadherence and loss to follow up at 1 month were assessed using linear regression models. Results 37.4% of the participants reported low adherence to services (≤ 3 pills/week or missed clinic schedule at month 1). Factors associated with low adherence included younger age (25 years and under) (adjusted odds ratio (aOR): 1.49, 95% confidence interval (95% CI: 1.01–2.21, p  = 0.044), being a TGW (aOR: 2.2, 95% CI: 1.27–3.83, p  = 0.005), and whether the participant had not previously accessed services at the clinic (aOR = 1.68, 95% CI: 1.03–2.76, p  = 0.04). Additionally, participants in Chonburi (the only TGW site) showed significantly lower adherence than those in the other three provinces (aOR: 2.91, 95% CI: 1.55–5.45, p  = 0.001). Conclusion Urgent, innovative interventions for early PrEP adherence support among vulnerable sub-populations such as younger users, TGW, and new clients are needed to maximize prevention strategy in Thailand.

Disclosure of HIV status to family members could improve communication, relationship, and cohesion. We evaluated the impact of a family-centered program designed to increase the readiness/willingness of parents to disclose HIV status to their children. People living with HIV (PLWH) with children ≥8 years were surveyed regarding HIV knowledge, family relationship, attitudes, willingness/readiness to disclose, and they were then invited to participate in group education and family camps. Of 367 PLWH surveyed, 0.8% had disclosed, 14.7% had not yet disclosed but were willing/ready to disclose, 50.4% were willing but not ready, and 33.2% did not wish to disclose. The educational sessions and camps led to significant improvements of HIV knowledge and disclosure techniques, and readiness/willingness to disclose. Given the benefits of group education and family camps in supporting PLWH to improve their communication with their families and disclose their HIV status, these supporting activities should be included in HIV programs.

The strategy comprised the following components (Figure 1): Development of training modules and administrative systems by IHRI, to facilitate certification of lay providers in HIV counselling, sample collection and conducting point-of-care tests for HIV and STI, and dispensing HIV-related medications as prescribed by doctors (e.g. PrEP). Development of a manual for quality standards for HIV service delivery, including key compentencies for lay providers, by IHRI in collaboration with The Department of Disease Control, MOPH and the Thailand MOPH—U.S. [...]of our ongoing advocacy and demonstration of successful implementation, MOPH issued a decree in 2019, allowing certified lay providers to deliver high-quality services (HIV counselling, sample collection for HIV and STI testing, conducting rapid/point-of-care tests and dispensing ART and PrEP as prescribed by doctors), signifying an important advance in regulatory reform to legalize lay providers to perform these services [ 6].

Background No data are available on the feasibility of pre-exposure prophylaxis (PrEP) delivered by trained key population (KP) community health workers. Herein we report data from the KP-led Princess PrEP program serving men who have sex with men (MSM) and transgender women (TGW) in Thailand. From January 2016 to December 2017, trained MSM and TGW community health workers delivered same-day PrEP service in community health centres, allowing clients to receive one PrEP bottle to start on the day of HIV-negative testing. Visits were scheduled at Months 1 and 3, and every 3 months thereafter. Uptake, retention and adherence to PrEP services and changes in risk behaviours over time are reported. Of 1467 MSM and 230 TGW who started PrEP, 44.1% had had condomless sex in the past 3 months. At Months 1, 3, 6, 9 and 12, retention was 74.2%, 64.0%, 56.2%, 46.7% and 43.9% respectively (lower in TGW than MSM at all visits; P<0.001), with adherence to at least four PrEP pills per week self-reported by 97.4%, 96.8%, 96.5%, 97.5% and 99.5% of respondents respectively (no difference between MSM and TGW). Logistic regression analysis identified age >25 years, being MSM and having at least a Bachelors degree significantly increased retention. Condomless sex did not change over the 12-month period (from 47.2% to 45.2%; P=0.20). New syphilis was diagnosed in 4.9% and 3.0% of PrEP clients at Months 6 and 12 (cf. 7.0% at baseline; P=0.007). Among PrEP adherers and non-adherers, there were one and six HIV cases of seroconversion respectively, which resulted in corresponding HIV incidence rates (95% confidence interval) of 0.27 (0.04-1.90) and 1.36 (0.61-3.02) per 100 person-years. Our KP-led PrEP program successfully delivered PrEP to MSM and TGW. Innovative retention supports are needed, especially for TGW and those who are young or with lower education levels. To scale-up and sustain KP-led PrEP programs, strong endorsement from international and national guidelines is necessary.

Despite the challenges to the HIV response in the Asia–Pacific, a demedicalisation of HIV intervention has been demonstrated to be an important strategy to maximise the uptake of HIV prevention tools among key populations in this region. Demedicalisation of HIV interventions translates medical discourse and shifts the paradigm from a disease-focused to a people-centred approach. It also recognises real-life experiences of key populations in the HIV response by empowering them to voice their needs and be at the forefront of the epidemic control. We further categorise a demedicalisation approach into three frameworks: (1) the demystification of clinical or medical concerns; (2) the destigmatisation of people living with HIV; and (3) the decentralisation of healthcare services. This article reviewed the demedicalisation framework by looking at the HIV intervention examples from countries in the Asia–Pacific, which included: (1) a study on drug–drug interaction between pre-exposure prophylaxis and feminising hormone treatment for transgender women; (2) the roles of key population-led health services; and (3) certification of key population lay providers.

Introduction Low uptake of HIV testing and services, including pre‐exposure prophylaxis (PrEP), in Thai men who have sex with men (MSM) and transgender women (TGW) may be due to the inaccuracy in self‐risk assessment. This study investigated the discordance between self‐perceived HIV risk and actual risk. Methods Data were obtained between May 2015 and October 2016 from MSM and TGW enrolled in key population‐led Test and Treat study in six community health centres in Thailand. Eligible participants were at least 18 years old, Thai national, had sex with men, had unprotected sex with a man in the past six months or had at least three male sex partners in the past six months, and were not known to be HIV positive. Baseline demographic behavioural characteristics questionnaires, including self‐perceived HIV risk, were self‐administered. Participants received HIV/STI (syphilis/gonorrhoea/chlamydia) testing at baseline. Participants who self‐perceived to have low risk, but engaged in HIV‐susceptible practices were categorized as having risk discordance (RD). Regression was conducted to assess factors associated with RD among MSM and TGW separately. Results Of the 882 MSM and 406 TGW participants who perceived themselves as having low HIV risk, over 80% reported at least one of the following: tested HIV positive, engaged in condomless sex, tested positive for a sexually transmitted infection sexually transmitted infection (STI; or used amphetamine‐type stimulants. Logistic regression found that living with a male partner (p = 0.005), having never tested for HIV (p = 0.045), and living in Bangkok (p = 0.01) and Chiang Mai (p < 0.001) were associated with increased risk discordance among MSM. Living with a male partner (p = 0.002), being less than 17 years old at sexual debut (p = 0.001), and having a low knowledge score about HIV transmission (p < 0.001) were associated with increased risk discordance among TGW. However, for TGW, being a sex worker decreased the chance of risk discordance (p = 0.034). Conclusions Future HIV prevention messages need to fill in the gap between self‐perceived risk and actual risk in order to help HIV‐vulnerable populations understand their risk better and proactively seek HIV prevention services.

Same-day anti-HIV testing algorithm is recommended by Thai National Guidelines. We compared performance characteristics of algorithms used in a mobile clinic and a facility-based clinic for men who have sex with men (MSM) in Bangkok. Mobile clinic samples collected from 4 saunas and 2 spa venues were tested by Alere DetermineTM HIV 1/2, followed by DoubleCheck GoldTM Ultra HIV 1/2 and SD Bioline HIV 1/2 3.0. All samples were re-tested at the Thai Red Cross Anonymous Clinic (TRCAC) by Architect HIV Ag/Ab or Elecsys HIV combi PT, followed by Alere DetermineTM HIV 1/2 and Serodia HIV 1/2. Non-reactive samples were tested by Aptima nucleic acid amplification test (NAAT) and reactive/inconclusive samples were tested by less-sensitive immunoassays (IA) and HIV-1 RNA to detect acute HIV infection (positive NAAT or non-reactive IA/positive HIV-1 RNA). Of 233 MSM, 36 (15.5%) had HIV infection diagnosed using mobile clinic algorithm. Two additional acute HIV cases (1 positive NAAT and 1 reactive Architect with detectable HIV-1 RNA) were diagnosed using TRCAC algorithm. The mobile clinic algorithm had a sensitivity of 94.9% (95% CI: 82.7, 99.4) and a specificity of 100% (95% CI: 98.1, 100). Use of whole blood on rapid test kits demonstrated satisfactory performance and allowed same-day HIV test result through a mobile clinic model. For populations with high HIV incidence, careful history taking to define the window period is crucial and repeat testing must be encouraged if the testing algorithm does not include 4th generation anti-HIV assay or NAAT.
