A Cross-sectional Study to Identify Risk Factors for Hepatitis C in Punjab, India.

BACKGROUND: Hepatitis C virus (HCV) antibody prevalence in Punjab, India (0.56%) is higher than the national average (0.32%), but primary drivers of local transmission are unclear. OBJECTIVES: The objective of this study was to identify behavioral and demographic predictors of screening positive for HCV in Punjab. MATERIALS AND METHODS: Interviews assessing exposure to potential HCV risk factors were administered cross-sectionally to persons screening for HCV across 10 treatment facilities. Risk ratios (RRs) were calculated using generalized estimating equation models accounting for clustering by health facility. RESULTS: One thousand seven hundred and sixty-three patients tested anti-HCV positive; 595 were negative. 57.7% of respondents were male; the median age was 40 years. 13.8% reported injecting drugs. Males were more likely to test positive than females (RR: 1.14, 95% confidence interval [CI]: 1.07-1.21). Unmarried men were at higher risk of anti-HCV positivity compared with married men (RR: 1.16, 95% CI: 1.08-1.24), but unmarried women were at lower risk (RR: 0.65, 95% CI: 0.43-0.98). The strongest risk factors were history of injecting drugs (RR: 1.37, 95% CI: 1.24-1.51), incarceration (RR: 1.22, 95% CI: 1.12-1.33), acupuncture use (RR: 1.20, 95% CI: 1.09-1.33), having household member(s) with a history of incarceration (RR: 1.17, 95% CI: 1.08-1.26), and tattoos (RR: 1.16, 95% CI: 1.09-1.24). Additional risk factors among men included receiving injections in a public hospital or from unregistered medical practitioners and among women included a history of childbirth. CONCLUSION: Injecting drugs was most strongly associated with anti-HCV positivity in this population. Greater attention to HCV prevention is needed, with a focus on people-centered harm reduction programs, behavioral change interventions, and increasing safety in potential transmission settings.

Patient outcomes in public sector hepatitis C treatment programmes: a retrospective cohort analysis across five low- and middle-income countries.

OBJECTIVES: Given limited data on factors associated with hepatitis C virus (HCV) treatment discontinuation and failure in low- and middle-income countries, we aimed to describe patient populations treated for HCV in five countries and identify patient groups that may need additional support. DESIGN: Retrospective cohort analysis using routinely collected data. SETTING: Public sector HCV treatment programmes in India (Punjab), Indonesia, Myanmar, Nigeria (Nasarawa) and Vietnam. PARTICIPANTS: 104 957 patients who initiated treatment in 2016-2022 (89% from Punjab). PRIMARY OUTCOMES: Treatment completion and cure. RESULTS: Patient characteristics and factors associated with outcomes varied across countries and facilities. Across all patients, median age was 40 years (IQR: 29-52), 30.6% were female, 7.0% reported a history of injecting drugs, 18.2% were cirrhotic and 4.9% were coinfected with HIV. 79.8% were prescribed sofosbuvir+daclastasvir. Of patients with adequate follow-up, 90.6% (89,551) completed treatment. 77.5% (69,426) of those who completed treatment also completed sustained virological testing at 12 weeks (SVR12), and of those, 92.6% (64 305) were cured. In multivariable-adjusted models, in most countries, significantly lower treatment completion was observed among patients on 24-week regimens (vs 12-week regimens) and those initiated in later years of the programme. In several countries, males, younger patients <20 years and certain groups of cirrhotic patients were less likely to complete treatment or be cured. In Punjab, treatment completion was also lower in those with a family history of HCV and people who inject drugs (PWID); in other countries, outcomes were comparable for PWID. CONCLUSION: High proportions of patients completed treatment and were cured across patient groups and countries. SVR12 follow-up could be strengthened. Males, younger people and those with decompensated cirrhosis on longer regimens may require additional support to complete treatment and achieve cure. Adequate programme financing, minimal user fees and implementation of evidence-based policies will be critical to close gaps.

HIV-1 Drug Resistance Among Treatment-Naive Transgenders from India.

Transgenders (TGs) are highly affected by HIV with high prevalence of 3.14% in India. Since 2017, targeted preventive efforts have been initiated by the government and HIV-infected TGs are being provided the antiretroviral (ART) treatment. Information on the primary HIV drug resistance is crucial for appropriate treatment selection to curb further spread of HIV in this population. In this study, we analyzed HIV-1 pol gene sequences from 36 TGs for presence of drug resistance mutations. To our knowledge, this first study from India reports high-level primary drug resistance (13.8%) among the TG population. Mutations M184V, A98G, K103N, G190A, and Y318F associated with resistance to nucleoside reverse transcriptase inhibitor and non-nucleoside reverse transcriptase inhibitors were observed. All pol gene sequences revealed HIV-1 subtype C in all study TG. High-level HIV-1 drug resistance warrant nationwide larger studies on TGs to understand the level of primary ART drug resistance among this population.

Factors Influencing Willingness to Use Human Immunodeficiency Virus Preexposure Prophylaxis Among Transgender Women in India.

Purpose: High levels of human immunodeficiency virus (HIV) prevalence and inconsistent condom use among transgender women in India highlight the need for additional effective HIV prevention methods like preexposure prophylaxis (PrEP). We examined the extent of and factors influencing willingness to use PrEP among trans women in India. Methods: Between June and August 2017, we conducted a cross-sectional survey among 360 trans women recruited through community-based organizations in six cities. We assessed PrEP knowledge, condom use, attitudes toward PrEP (after providing information on PrEP), preferences in PrEP pricing and access venues, discrimination experiences, and the likelihood of using PrEP. Logistic regression analyses were conducted. Results: Participants' median age was 26 years; 50.7% had not completed high school, and 24.8% engaged in sex work. Only 17.1% reported having heard of PrEP before the survey, and 80.6% reported that they would definitely use PrEP. Trans women in sex work had 28 times higher odds of reporting willingness to use PrEP than those not in sex work (adjusted odds ratio [aOR]=28.9, 95% confidence interval [CI]=8.79-95.16, p<0.001). When compared with trans women who did not experience discrimination, the odds of reporting willingness to use PrEP was lower among trans women who had experienced discrimination from health care providers (aOR=0.25, 95% CI=0.06-0.97, p=0.04) and family members (aOR=0.08, 95% CI=0.05-0.14, p<0.001). Conclusion: Willingness to use PrEP was high among trans women, especially those in sex work, despite identified barriers (e.g., discrimination experiences). To promote PrEP uptake among at-risk trans women, the steps needed are as follows: increasing awareness about PrEP; providing easy-to-understand information on PrEP's effectiveness, side effects and interactions between PrEP and hormones; training health care providers on PrEP and cultural competency; and reducing stigmas related to PrEP use and HIV. PrEP implementation research projects to identify effective PrEP delivery strategies are urgently needed to reduce the disproportionate HIV burden among trans women in India.
