Risk Factors for HIV Seroconversion in a High Incidence Cohort of Men Who Have Sex with Men and Transgender Women in Bangkok, Thailand

Background Hepatitis A is a fecal-oral infection caused by hepatitis A virus (HAV). Men who have sex with men (MSM) and transgender women (TW) have been reported as target groups for HAV infection. This study aimed to determine the seroprevalence, risk factors, and circulating strains associated with HAV infection among MSM and TW in Central Brazil. Methods A cross-sectional study was conducted from November 2011 to September 2013. Serum samples were collected from 425 individuals for anti-HAV antibody testing and HAV molecular characterization. Of them, 149 (35.1%) participants were self-identified as transgender women. Statistical analysis was performed to evaluate the risk factors of HAV seropositivity. Results The seroprevalence of HAV exposure was 69.7% (95% Confidence Interval: 65.3–74.0%). Serological evidence of HAV was significantly higher in participants who self-identified as transgender women (83.2%) than MSM (62.3%). Increasing age, non-white race, and lower monthly household income were independently associated with HAV exposure among MSM. Only lower monthly household income was independently associated with HAV exposure among TW. One anti-HAV IgM positive sample, from a transgender woman (0.2%), was detected and classified as subgenotype IA. Conclusions High HAV prevalence was observed, markedly among TW. Considering the risky sexual behaviors this population is exposed to, HAV vaccination and prevention programs targeting this population should be considered to prevent outbreaks and the burden of the disease.

Control Study

Background and purpose: HIV prevalence among men who haved sex with men (MSM) increased from 5% on 2007 into 12% on 2011 in Indonesia. High risk sex behaviour was reported associated with HIV seroconversion, however reported research publication about risk factors of HIV seroconvertion among MSM is limited in Indonesia. This study aim to investigate risk factors of HIV seroconversion among MSM.Methods: Case control study was conducted based on cohort data from MSM which repeatetly visit Bali Medika Clinic, Kuta, Badung, Bali Province between 2011-2015. HIV Seroconversion was defined as MSM with a negative HIV status at the beginning of the observation and became positive on the next visit. Data were analyzed using Kaplan Meier and logistic regression method.Results: Median time of HIV seroconversion among MSM was 458 days or 1.2 years (IQR=224-699). Multivariate analysis showed that risk factors of HIV seroconversion were repeated STD’s experience in the last 6 months with AOR=8.33 (95%CI: 1.77-89.81); had 1 time STD’s history in last 6 months with AOR=1.91 (95%CI: 1.15-3.83); receptive sexual relationship in the last 6 months with AOR=3,45 (95%CI: 1.68-7.11); and versatile sexual relationship in the last 6 months with AOR=2.37 (95%CI: 1.09-5.13).Conclusion: STD’s experience, receptive and versatile sexual role was reported as risk factors of HIV seroconversion among MSM.

Active Syphilis

Background Syphilis in Peru is heavily concentrated in men who have sex with men (MSM) and transgender women (TGW). The aim of the present study was to understand the risk factors for active syphilis infection among MSM and TGW in Peru. Methods: Independent correlates suggestive of active syphilis infection were examined to better understand risk factors for syphilis in MSM and TGW, with separate analyses conducted based on location and among TGW. In 2011, 5101 MSM and TGW completed both self-report surveys and HIV and syphilis testing in five Peruvian cities. Results: Overall, 261 (5.1%) MSM and TGW met the criteria for active syphilis, with higher prevalence in Lima than elsewhere (7.0% vs 3.0%) and in TGW than in MSM (10.7% vs 4.2%). Significant independent correlates of active syphilis infection differed greatly by location. In Lima, they included being HIV-infected (aware or unaware of status), being a TGW, being a high school graduate, engaging in receptive anal intercourse, no recent sex with a female partner and having had any symptomatic sexually transmissible infection, including syphilis, in the previous 6 months. Outside Lima, the independent correlates included being HIV-infected and unaware of status, engaging in recent sex work, no recent sex with a female partner and age 35–44 years. Among TGW, independent correlates of active syphilis included being HIV-infected (aware or unaware of status), a recent syphilis diagnosis in the previous 6 months and recent drug use. Conclusion: The findings of the present study support the need not only for combined HIV and syphilis screening, but also for increased screening and treatment of syphilis in MSM and TGW populations. Stratified analyses suggest different syphilis epidemics throughout the country and in TGW, yet being HIV-infected and aware were consistently associated with active syphilis, suggesting higher syphilis risk in HIV-infected MSM and TGW.
