Prevalence and the associated factors of hepatitis B and hepatitis C viral infections among HIV-positive individuals in same-day antiretroviral therapy initiation program in Bangkok, Thailand
Background
Viral hepatitis is highly prevalent among people with HIV (PWH) and can lead to chronic liver complications. Thailand started universal hepatitis B vaccination at birth in 1992 and achieved over 95% coverage in 1999. We explored the prevalence of hepatitis B and C viral infections and the associated factors among PWH from same-day antiretroviral therapy (SDART) service at the Thai Red Cross Anonymous Clinic, Bangkok, Thailand.
Methods
We collected baseline characteristics from PWH enrolled in the SDART service between July 2017 and November 2019. Multivariable logistic regression was performed to determine factors associated with positive hepatitis B surface antigen (HBsAg) and hepatitis C antibody (anti-HCV).
Results
A total of 4011 newly diagnosed PWH who had HBsAg or anti-HCV results at baseline: 2941 men who have sex with men (MSM; 73.3%), 851 heterosexuals (21.2%), 215 transgender women (TGW; 5.4%), and 4 transgender men (0.1%). Median age was 27 years. Overall seroprevalence of HBsAg and anti-HCV were 6.0 and 4.1%, respectively. Subgroup prevalence were 6.2 and 4.7% among MSM, 4.6 and 2.4% among heterosexuals, and 9.3 and 3.7% among TGW, respectively. Factors associated with HBsAg positivity were being MSM, TGW, born before 1992, CD4 count 30 years, alanine aminotransferase ≥ 62.5 U/L, creatinine clearance < 60 ml/min, and syphilis infection.
Conclusions
Around 5–10% of newly diagnosed PWH in Bangkok had hepatitis B viral infection after 25 years of universal vaccination. Anti-HCV positivity was found in 4–5% of PWH who were MSM and TGW. As World Health Organization and Thailand national guidelines already support routine screening of hepatitis B and C viral infections in PWH and populations at increased risk of HIV including MSM and TGW, healthcare providers should reinforce this strategy and provide linkage to appropriate prevention and treatment interventions. Catch-up hepatitis B vaccination should be made available under national health coverage
Acceptability and retention of the key population‐led HIV treatment service for men who have sex with men and transgender women living with HIV in Thailand
Abstract Introduction In Thailand, where the HIV epidemic is concentrated among key populations (KPs), particularly men who have sex with men (MSM) and transgender women (TGW), an HIV service delivery model tailored to KPs was piloted. This study evaluated the acceptability and retention of clients who accepted and declined the KP‐led HIV treatment service. Methods A retrospective cohort study was conducted using secondary data from three community‐based organizations (CBOs) and three hospitals in Thailand. KP lay providers were trained to lead HIV treatment service in which MSM and TGW living with HIV received counselling and a 3‐month antiretroviral therapy (ART) supply at CBOs. Thai MSM and TGW who were at least 18 years, on ART for at least 6–12 months, without co‐morbidities/co‐infections, and virally suppressed were eligible and offered the service. Those who declined received ART via other service models offered by the hospitals and served as a comparison group. Results Of 220 clients screened between February 2019 and February 2020, 72% (159/220) were eligible of which 146 were MSM and 13 were TGW. Overall, 45% (72/159) accepted the KP‐led service. Of those who declined, 98% (85/87) preferred to see the physician at the hospital. After 12 months of follow‐up, among those accepted, 57% were in care at the CBO, 32% were referred back to and in care in other service models offered by the hospital, 10% were successfully transferred out to other hospital and 1% were lost to follow‐up (LTFU); among those declined, 92% were in care in any service models offered by the hospital, 5% were successfully transferred out to other hospital, 2% were LTFU and 1% died (p‐value<0.001). Conclusions Despite moderate acceptability and retention in care at the CBO among the clients accepting the KP‐led service, almost all clients were engaged in care overall. Multiple service models that meet the preferences and needs of KPs living with HIV should be available to optimize engagement in care

The epidemiological impact and cost-effectiveness of key population-led PrEP delivery to prevent HIV among men who have sex with men in Thailand: A modelling study
Background: Although key populations (KPs), such as men-who-have-sex-with-men (MSM) are disproportionately affected by HIV, many prevention and treatment services are not easily accessible for KP members. To address the needs of KPs, Thailand established pre-exposure prophylaxis (PrEP) service delivery together with and led by KP members. This study determines the epidemiological impact and cost-effectiveness of key population-led (KP-led) PrEP. Methods: We calibrated a compartmental deterministic HIV transmission model to the HIV epidemic among Thai MSM. Besides KP-led PrEP, we included other Thai service delivery models of PrEP (fee-based PrEP, the government PrEP program).Data on consistent PrEP use (5 years daily use, 95% effectiveness for preventing HIV) came from Thai PrEP delivery models. For the period 2015–2032, we ranged the number of PrEP starters (40,000–120,000), effectiveness of PrEP (45%–95%), and proportion of consistent users (10%–50%). The analysis started in 2015 when PrEP was introduced. A cost-effectiveness ratio of <160,000 Baht per quality-adjusted life year (QALY) over 40 years was cost-effective. Findings: Without PrEP, 53,800 (interquartile range 48,700–59,700) new HIV infections are expected in 2015–2032. KP-led PrEP was found to have the strongest epidemiological impact of all delivery models averting 58% of infections compared to without PrEP. The epidemiological impact depends on the number of PrEP starters and proportion of consistent use. Although all PrEP service delivery models are cost-effective, KP-led PrEP is most cost-effective with incremental cost-effectiveness ratios of 28,000–37,300 Thai Baht per QALY. Interpretation: Our model projects KP-led PrEP having the greatest epidemiological impact and being the most cost-effective service delivery model of PrEP in Thailand.
