RESUMEN
Data are lacking or outdated on burden of HIV, viral hepatitis infection, and sexually transmitted infections such as syphilis among people deprived of liberty in the Asia-Pacific region. We aimed to evaluate the proportion of viral hepatitis B (HBV), hepatitis C (HCV), HIV, and syphilis infections, and factors associated with HCV, HBV, and HIV infection in a central male prison. A cross-sectional study was performed among 1,028 people deprived of liberty from a central male prison in Bangkok, Thailand. People deprived of liberty were screened for HIV, HBV, HCV, and syphilis infections during 2018-2019. HBV and HCV were defined as positive hepatitis B surface antigen and positive anti-HCV antibody, respectively. Proportions (95% confidence interval [CI]) of infections were calculated based on the binomial distribution. HBV proportion was reported for different age groups. Risk factors associated with HCV infections were evaluated by logistic regression model. The median age was 38 (interquartile range, 32-50) years, and 6.9% reported use of injection drugs. The proportion of HIV, HBV, anti-HCV, HCV RNA, and syphilis was 2.9% (95% CI, 1.9-4.1), 6.4% (5-8.1), 5.9% (4.6-7.6), 4.2% (3-5.6), and 4.8% (3.5-6.3), respectively. One (0.1%), 7 (0.6%), and 2 (3%) were co-infected with HIV/HBV, HIV/HCV, and HDV/HBV, respectively. HBV proportion differed across age groups: 3.7% in <30 years, 7% in 31-40 years, 9.7% in 41-50 years, and 5.5% in >50 years. Factors associated with HCV infection were older age, lower education level, previous incarceration, and injection drug use. In multivariable models, older age was associated with HBV infection, and men having sex with men was associated with HIV infection. The proportion of blood-borne infections was higher among males than among the general population. HBV vaccination, routine HCV screening, and treatment with pan-genotypic direct-acting antivirals with minimal specialist requirements should be implemented in Thai prisons.

BACKGROUND: This study investigated the sustained virologic responses (SVRs) among prisoners with hepatitis C virus (HCV) using universal test-and-treat approach by prison health care workers in a central male prison in Thailand. METHODS: A universal HCV screening was conducted in a maximum-security central prison (Klong Prem Central Prison) in Thailand. HCV RNA-confirmed prisoners were treated with generic sofosbuvir/velpatasvir by prison health care workers, regardless of their HCV genotypes and duration of prison sentences. We evaluated the SVR rates at 12 weeks after completing direct acting antivirals (DAA) treatment. RESULTS: A total of 68 prisoners with detectable HCV RNA received DAA treatment. The median age and duration of prison sentences were 44 years (interquartile range, 41-53) and 25 (interquartile range, 19-33) years, respectively. Twenty-five percentage of the participants was coinfected with HIV, and 6% of the participants was coinfected with hepatitis B virus. Among all prisoners who received DAA treatment, 20 (29%) had genotype (GT)-1a, 3 (4%) had GT-1b, 22 (32%) had GT-3a, 3 (4%) had GT-3b, and 7 (10%) had GT-6. Overall, improvements in liver biomarkers were seen after HCV treatment, and SVR was achieved in 97% of the participants with per-protocol analysis and in 90% of the participants with intention-to-treat analysis. CONCLUSIONS: HCV treatment using DAA among prisoners through universal test-and-treat approach led by prison health care workers is highly effective and safe, and such model can potentially help to facilitate the goals of HCV microelimination among prisoners in Thailand.

BACKGROUND: Prisons are considered as major reservoirs for tuberculosis. Preventive therapy for latent TB infection (LTBI) is an adjunctive strategy to control TB. However, LTBI data in Thai prisoners is limited. This study assessed the prevalence of LTBI and feasibility of isoniazid preventive therapy (IPT). METHODS: A cross-sectional study was conducted among prisoners in Klong Prem Central Prison, Bangkok. Participants were screened for active TB by questionnaire and chest X-ray. LTBI was evaluated by Tuberculin skin test (TST) and QuantiFERON-TB Gold Plus (QFTP) among subgroup. Participants with positive TST or QFTP were considered to have LTBI. Participants with LTBI were offered IPT. RESULTS: From August 2018-November 2019, 1002 participants were analyzed. All participants were male with a median age of 38 (IQR 32-50) years. LTBI identified by either TST/QFTP was present in 466 (46.5%) participants. TST was positive in 359 (36%) participants. In the subgroup of 294 participants who had both TST and QFTP results, 181/294 (61.6%) tested positive by QFTP. Agreement between TST and QFTP was 55.1% (Kappa = 0.17). The risk factors associated with LTBI were previous incarceration (aOR 1.53, 95%CI, 1.16-2.01, p = 0.002), history of prior active TB (aOR 3.02, 95%CI, 1.74-5.24, p < 0.001) and duration of incarceration ≥10 years (aOR 1.86, 95%CI, 1.24-2.79, p = 0.003). Majority of LTBI participants (82%) agreed to take IPT. Three hundred and 56 (93%) participants completed treatment whereas 27 (7%) participants discontinued IPT due to the side effects of INH. CONCLUSION: This is the first study to evaluate the prevalence of LTBI and feasibility of IPT among Thai prisoners. LTBI prevalence in male prisoners in Thailand is high. LTBI screening and treatment should be implemented together with other preventive components.
