Here, we evaluated the impact of incorporating risk heterogeneity in transmission models on the predicted effects of interventions and the feasibility of HCV elimination in high-burden settings. We built an individual-based model of HCV transmission informed by detailed data from a cohort of PWID in Baltimore, MD, including an individual- and time-varying risk multiplier on the force of infection. We contrasted these risk-informed models to risk-agnostic models, ignoring this heterogeneity, and explored various levels of treatment and harm reduction scale-up from 2020 to 2030. Risk-agnostic models routinely estimated greater reductions in incidence (8%–19% higher for treatment rates of 10–90 per 100 PY) and greater numbers of infections averted per treatment course compared to otherwise equivalent populations modelled with risk heterogeneity. Elimination targets were only achieved in risk-informed models when treating 90 PWID per 100 PY. Expanding harm reduction services dramatically improved the impact of elimination programs, particularly in averting new infections soon after treatment scale-up initiation. Achieving HCV elimination targets among PWID in high-burden settings will require substantial improvements in treatment access and harm reduction services. Models that ignore the unequal distribution of HCV risk, including the correlation between reinfection risk and onward transmission, can result in inappropriately optimistic estimates of the feasibility of elimination.</p>","PeriodicalId":17762,"journal":{"name":"Journal of Viral Hepatitis","volume":"32 11","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12522077/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145292605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While patients are classified based on dominance patterns, the impact on the immune system remains largely unknown. It is recognised that HBV reactivation may occur following HCV clearance. This study aims to explore the potential immune interactivity between HCV and HBV by analysing patterns of soluble immune mediators (SIM). A total of 58 soluble immune mediators were measured in serum or plasma samples of 49 patients chronically infected with hepatitis B and hepatitis C virus in a cross-sectional study design. Patients were classified based on dominance patterns: HBV dominance (<i>n</i> = 8), HCV dominance (<i>n</i> = 22), HBV and HCV codominance (<i>n</i> = 11) and no dominance (<i>n</i> = 8). SIM expression was distinct based on different dominance patterns. HBV activity induced higher SIM expression and altered the soluble inflammatory milieu (22 SIM altered, <i>p</i> &lt; 0.05). Altered pathways included JAK–STAT pathway (<i>p</i> = 1.36 × 10<sup>−20</sup>), IL-17 signalling (<i>p</i> = 2.47 × 10<sup>−13</sup>) and Th17 cell differentiation (<i>p</i> = 1.69 × 10<sup>−9</sup>).

The aim of this study was to investigate the factors influencing adherence to BLV treatment in real-life settings in Italy. From May to September 2024, two anonymous surveys—one for HDV patients undergoing bulevirtide (BLV) treatment and one for their hepatologists—were conducted across five tertiary centers in Italy. The study employed the COM-B model (Capability, Opportunity, Motivation–Behaviour) to systematically explore the behavioural drivers influencing treatment adherence in this population and unmet needs.

The findings revealed key challenges related to patient education, logistical access to medication, and psychological factors affecting motivation.

Primary care and addiction providers similarly emphasized the convenience and usual practice of referring patients to specialists for HCV treatment, while infectious disease and gastroenterology noted challenges with patients not completing the referrals. Primary care providers expressed wanting training and peer support related to treatment provision. Addiction providers described structural barriers, such as lacking on-site phlebotomy services and patients' competing health concern prioritization, but highlighted strategies to improve treatment access, including trust-building. Infectious disease providers highlighted using patient navigators to overcome logistical barriers, while gastroenterologists emphasized collaborative relationships, particularly with addiction specialists. Specialty-specific opportunities emerged regarding training, collaboration, navigation, and infrastructure.

Here, we report the safety and efficacy of a pangenotypic generic HCV treatment among PWID in Vietnam, using a sofosbuvir/daclatasvir regimen. PWID were screened for HCV at two community-based organisations (CBO) premises in Haiphong during both a respondent-driven sampling survey and cohort follow-up visits.

Collection and preservation of plasma, the preferred specimen type, is challenging in some areas. The Cobas Plasma Separation Card (PSC) is an alternative specimen type with no cold chain requirements. The PSC is designed to use capillary blood from fingerstick and capillary tube collection, but alternative sample collection options would broaden PSC utility. This study explored qualitative and quantitative HCV RNA detection with PSC prepared using a syringe needle, compared to plasma. Using a 24-gauge syringe, blood was drawn by venipuncture from HCV antibody-positive clinic patients aged &gt; 18 years and used to prepare plasma or spotted directly onto three PSCs using 6, 8 and 10 drops per spot (group 1) or 8, 10 and 12 drops (group 2). HCV RNA was measured using the Cobas HCV assay. Test results for all conditions were available for 143 patients in group 1 and 109 patients in group 2. The proportions with detectable HCV RNA were not significantly different from plasma, and overall agreement was over 88% for any PSC spot number (Fisher exact test <i>p</i> &gt; 0.1). The mean HCV viral load was lower for PSC samples vs. plasma for six or eight spots in group 1 but not statistically different for 10 or 12 spots in either group. Direct spotting of blood using a syringe is a viable alternative to finger prick and capillary tube transfer for PSC preparation. This approach may be beneficial in resource-limited settings and in patient populations for whom capillary blood collection is challenging.</p>","PeriodicalId":17762,"journal":{"name":"Journal of Viral Hepatitis","volume":"32 11","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jvh.70091","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145146590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
