Simplification of Care for Chronic Hepatitis C Virus Infection

Optimizing Hepatitis C Treatment Monitoring: Is Sustained Virologic Response at 4 Weeks Becoming the New Standard?

This study, conducted at two university-based infectious disease clinics, included 216 patients with chronic hepatitis C. The primary objective was to assess the positive and negative predictive values, sensitivity, and specificity of achieving a sustained virological response (SVR) at 4 weeks compared to 12 weeks post-therapy. The results demonstrated a maximum sensitivity of 100% for achieving SVR at 12 weeks after reaching SVR at 4 weeks for all analyzed genotypes, except for genotype 1b treated with EBR/GZR therapy, where the specificity was 75%. Additionally, younger age and less advanced liver fibrosis were identified as independent predictors of achieving a sustained virological response at both 4 and 12 weeks. The significant normalization of various biochemical parameters was observed after treatment, indicating an overall improvement in liver function. This study suggests that shortening the monitoring period to 4 weeks might be effective for younger patients without significant fibrosis, potentially reducing loss to follow-up, which is a critical issue in HCV treatment. These findings align with the "test and treat" approach. Further research is needed to confirm these findings and incorporate them into official guidelines, which could simplify and enhance the effectiveness of HCV treatment protocols, aiding global efforts to eliminate HCV as a public health issue by 2030.

Screening rates for hepatitis B and C among low-income US veterans: Data from the National Veteran Homeless and Other Poverty Experiences Study

Screening for viral hepatitis is considered a high-priority area in the Veterans Health Administration (VHA). Yet, few studies have examined viral hepatitis screening test use among low-income veterans who are considered high-risk with limited healthcare access. Using cross-sectional data from 933 participants in the 2021-2022 National Veteran Homeless and Other Poverty Experiences (NV-HOPE) study, we examined rates and correlates of lifetime screening for hepatitis B (HBV) and hepatitis C (HCV) infections. Multivariable logistic regression models evaluated characteristics associated with HBV/HCV screening. Nearly 16% and 21% reported lifetime HBV and HCV screening, respectively. These rates are considerably lower than HBV (47.3%) and HCV (92.9%) screening rates documented among contemporaneous veterans in VHA electronic health records. In the NV-HOPE data, veterans 50-79 years were more likely than those ≥80 years of age to ever-screen for HBV/HCV. Whereas, household income was inversely related to lifetime screening behaviours, veterans reporting 'other' employment types (vs. full-time/part-time employment) were more likely to ever-screen for HBV/HCV. Ever-screening for HBV was more likely among veterans reporting non-Hispanic 'other' (vs. non-Hispanic 'white') race, housing instability, Medicaid insurance, as well as drug use and cognitive disorder histories. Living with ≥5 members (vs. alone), histories of alcohol use, cancer, and liver disorders were also correlated with ever-screening for HCV. HIV/AIDS history correlated with ever-screening for HBV/HCV. In conclusion, fewer than one-third of low-income US veterans ever-screened for HBV/HCV, with lower screening rates among those less likely to be exposed to viral hepatitis, thereby informing interventions aimed at promoting available screening, treatment and vaccinations for HBV/HCV.

Contemporary Insights into Hepatitis C Virus: A Comprehensive Review

Hepatitis C virus (HCV) remains a significant global health challenge. Approximately 50 million people were living with chronic hepatitis C based on the World Health Organization as of 2024, contributing extensively to global morbidity and mortality. The advent and approval of several direct-acting antiviral (DAA) regimens significantly improved HCV treatment, offering potentially high rates of cure for chronic hepatitis C. However, the promising aim of eventual HCV eradication remains challenging. Key challenges include the variability in DAA access across different regions, slightly variable response rates to DAAs across diverse patient populations and HCV genotypes/subtypes, and the emergence of resistance-associated substitutions (RASs), potentially conferring resistance to DAAs. Therefore, periodic reassessment of current HCV knowledge is needed. An up-to-date review on HCV is also necessitated based on the observed shifts in HCV epidemiological trends, continuous development and approval of therapeutic strategies, and changes in public health policies. Thus, the current comprehensive review aimed to integrate the latest knowledge on the epidemiology, pathophysiology, diagnostic approaches, treatment options and preventive strategies for HCV, with a particular focus on the current challenges associated with RASs and ongoing efforts in vaccine development. This review sought to provide healthcare professionals, researchers, and policymakers with the necessary insights to address the HCV burden more effectively. We aimed to highlight the progress made in managing and preventing HCV infection and to highlight the persistent barriers challenging the prevention of HCV infection. The overarching goal was to align with global health objectives towards reducing the burden of chronic hepatitis, aiming for its eventual elimination as a public health threat by 2030.

Effectiveness and safety of glecaprevir/pibrentasvir for 8 weeks in the treatment of patients with acute hepatitis C: A single-arm retrospective study

BACKGROUND AND AIMS

No direct-acting antiviral is currently approved for acute HCV infection, delaying treatment. We investigated the effectiveness and safety of 8-week glecaprevir/pibrentasvir (G/P) in patients with acute HCV infection.

APPROACH AND RESULTS

This noninterventional, single-arm, retrospective chart review was designed to enroll adults/adolescents with acute HCV infection. Analyses were conducted on a full analysis set (FAS; all enrolled) and modified FAS (FAS excluding nonvirologic failures). The primary end point (modified FAS) was sustained virologic response at posttreatment week 12 (SVR12) with superiority to 92.6% threshold determined by historic chronic HCV G/P SVR12 rates. Secondary end points (FAS) included SVR12, on-treatment virologic failure, posttreatment relapse, and reinfection. Adverse events and safety laboratory values were assessed.Overall, 202 adults were enrolled; in the modified FAS, 150/151 (99.3%; 95% CI: 96.3-99.9) achieved SVR12, demonstrating superiority to efficacy threshold. In the FAS, the SVR12 rate was 74.3% and the on-treatment virologic failure rate was 0%. Relapse and reinfection rates after the final treatment visit (FAS) were 0.5% and 3%, respectively; 39 patients had missing SVR12 data. No on-treatment alanine aminotransferase elevations > 3 × upper limit of normal with total bilirubin > 2 × upper limit of normal were reported. All 53 patients with alanine aminotransferase Grade ≥ 2 at baseline improved to Grade 0/1 on treatment. No adverse eventss of hepatic decompensation/failure or leading to G/P discontinuation occurred. Two patients had serious adverse events unrelated to G/P.

CONCLUSIONS

Eight-week G/P therapy was effective and well-tolerated in patients with acute HCV infection. Data support further investigation of G/P in acute HCV to shorten care cascades, reduce transmission, and support HCV elimination.

Progress towards elimination of viral hepatitis: a Lancet Gastroenterology & Hepatology Commission update

The top 20 highest burdened countries (in disability-adjusted life years) account for more than 75% of the global burden of viral hepatitis. An effective response in these 20 countries is crucial if global elimination targets are to be achieved. In this update of the Lancet Gastroenterology & Hepatology Commission on accelerating the elimination of viral hepatitis, we convene national experts from each of the top 20 highest burdened countries to provide an update on progress. Although the global burden of diseases is falling, progress towards elimination varies greatly by country. By use of a hepatitis elimination policy index conceived as part of the 2019 Commission, we measure countries' progress towards elimination. Progress in elimination policy has been made in 14 of 20 countries with the highest burden since 2018, with the most substantial gains observed in Bangladesh, India, Indonesia, Japan, and Russia. Most improvements are attributable to the publication of formalised national action plans for the elimination of viral hepatitis, provision of publicly funded screening programmes, and government subsidisation of antiviral treatments. Key themes that emerged from discussion between national commissioners from the highest burdened countries build on the original recommendations to accelerate the global elimination of viral hepatitis. These themes include the need for simplified models of care, improved access to appropriate diagnostics, financing initiatives, and rapid implementation of lessons from the COVID-19 pandemic.

Molecular evolution, virology and spatial distribution of HCV genotypes in Pakistan: A meta-analysis

Background

Hepatitis C, caused by the Hepatitis C Virus (HCV), is the second most common form of viral hepatitis. The geographical distribution of HCV genotypes can be quite complex, making it challenging to ascertain the most prevalent genotype in a specific area.

Methods

To address this, a review was conducted to determine the prevalence of HCV genotypes across various provinces and as a whole in Pakistan. The scientific literature regarding the prevalence, distribution, genotyping, and epidemiology of HCV was gathered from published articles spanning the years 1996-2020.

Results

Genotype 1 accounted for 5.1% of the patients, with its predominant subtype being 1a at 4.38%. The frequencies of its other subtypes, 1b and 1c, were observed to be 1.0% and 0.31% respectively. Genotype 2 had a frequency of 2.66%, with the most widely distributed subtype being 2a at 2.11% of the patients. Its other subtypes, 2b and 2c, had frequencies of 0.17% and 0.36% respectively. The most prevalent genotype among all isolates was 3 (65.35%), with the most frequent subtype being 3a (55.15%), followed by 3b (7.18%). The prevalence of genotypes 4, 5, and 6 were scarce in Pakistan, with frequencies of 0.97%, 0.08%, and 0.32% respectively. The prevalence of untypeable and mixed genotypes was 21.34% and 3.53% respectively. Estimating genotypes proves to be a productive method in assisting with the duration and selection of antiviral treatment. Different HCV genotypes can exhibit variations in their response to specific antiviral treatments. Different genotypes may have distinct natural histories, including variations in disease progression and severity. Some genotypes may lead to more rapid liver damage, while others progress more slowly.

Conclusions

This information can guide screening and testing strategies, helping to identify individuals at higher risk of developing severe complications. Studying the distribution of HCV genotypes in a population can provide valuable insights into the transmission dynamics of the virus.

Cascade of Care for Hepatitis C Virus Infection Among Young Adults Who Inject Drugs in a Rural County in New Mexico

OBJECTIVE

Treatment for hepatitis C virus (HCV) infection is highly effective; however, people who inject drugs (PWID), the population most affected by HCV, may encounter barriers to treatment. We examined the cascade of care for HCV infection among young adult PWID in northern New Mexico, to help identify gaps and opportunities for HCV treatment intervention.

METHODS

Young adults (aged 18-29 y) who self-reported injection drug use in the past 90 days were tested for HCV antibodies (anti-HCV) and HCV RNA. We asked participants with detectable RNA to participate in an HCV education session, prior to a referral to a local health care provider for treatment follow-up, and to return for follow-up HCV testing quarterly for 1 year. We measured the cascade of care milestones ranging from the start of screening to achievement of sustained virologic response (SVR).

RESULTS

Among 238 participants, the median age was 26 years and 133 (55.9%) were men. Most (90.3%) identified as Hispanic. Of 109 RNA-positive participants included in the cascade of care assessment, 84 (77.1%) received their results, 82 (75.2%) participated in the HCV education session, 61 (56.0%) were linked to care through a medical appointment, 27 (24.8%) attended the HCV treatment appointment, 13 (11.9%) attended their follow-up appointment, 6 (5.5%) initiated treatment, 3 (2.8%) completed treatment, and 1 (0.9%) achieved SVR.

CONCLUSIONS

We observed a steeply declining level of engagement at each milestone step of the cascade of care after detection of HCV infection, resulting in a suboptimal level of HCV treatment and cure. Programs that can streamline testing and expand access to treatment from trusted health care providers are needed to improve the engagement of PWID in HCV treatment.

Stages of care for patients with chronic hepatitis C at a hospital in southern Brazil

BACKGROUND

Hepatitis C virus (HCV) is defined as a public health problem by the World Health Organization (WHO) and since then has defined targets through the HCV elimination. The HCV cascade of care highlights the progress towards these goals and essential interventions that need to be delivered along this continuum care.

AIM

To document the treatment cascade for patients with HCV infection at the Hospital Nossa Senhora da Conceição (HNSC), defining the percentage of antibody-positive patients who collected molecular biology tests (polymerase chain reaction), attended outpatient clinic assistance, underwent treatment, and achieved a virologic cure termed sustained virologic response (SVR).

METHODS

With the retrospective cohort design, patients diagnosed with HCV infection in the period between January 1, 2015 and December 31, 2020 were included. Data from HCV notification forms, electronic medical records, Computerized Laboratory Environment Manager System, and Medicine Administration System (evaluation of special medications) were collected in 2022 and all information up to that period was considered. The data were analyzed with IBM SPSS version 25, and Poisson regression with robust simple variance was performed for analysis of variables in relation to each step of the cascade. Variables with P < 0.20 were included in the multivariate analysis with P < 0.05 considered significant. Pearson's chi-square test was applied to compare the groups of patients who persisted in follow-up at the HNSC and who underwent follow-up at other locations.

RESULTS

Results were lower than expected by the WHO with only 49% of candidates receiving HCV treatment and only 29% achieving SVR, despite the 98% response rate to direct acting antivirals documented by follow-up examination. The city of origin and the place of follow-up were the variables associated with SVR and all other endpoints. When comparing the cascade of patients who remained assisted by the HNSC vs external patients, we observed superior data for HNSC patients in the SVR. Patients from the countryside and metropolitan region were mostly assisted at the HNSC and the specialized and continuous care provided at the HNSC was associated with superior results, although the outcomes remain far from the goals set by the WHO.

CONCLUSION

With the elaboration of the HCV cascade of care using local data, it was possible to stratify and evaluate risk factors associated with losses between each step of the cascade, to inform new strategies to guide elimination efforts in the future.

Time to HCV Treatment Disfavors Patients Living with HIV/HCV Co-infection: Findings from a Large Urban Tertiary Center

This study aimed to assess time to hepatitis C (HCV) treatment (i.e., the time between the initial clinic visit for HCV evaluation and the HCV treatment start date), to compare clinical characteristics between patients who received HCV treatment ≥ and < 6 months, and to identify predictors of longer time to HCV treatment in patients living with HCV. This study conducted a retrospective secondary analysis of patients living with HCV mono-infection and HIV/HCV co-infection who received HCV treatment with DAAs (n=214) at a HIV Clinic. Binomial logistic regression was used to identify predictors of longer time to treatment (i.e., ≥ 6 months). The median time to HCV treatment was 211 days. Compared to patients who were treated < 6 months, a higher proportion of patients who were treated ≥ 6 months had HIV/HCV co-infection (31% vs. 49%, p=0.01) and chronic kidney disease (8% vs. 18%, p=0.03). In multivariate analysis, HIV/HCV co-infection was positively associated with a longer time to HCV treatment (adjusted odds ratio, aOR=2.0, p=0.03). Time to HCV treatment disparities between African American and White American did not emerge from the analysis, but time to HCV treatment disfavored patients living with HIV/HCV co-infection. Studies are needed to identify and eliminate factors that disfavor patients living with HIV/HCV co-infection.

Chemokines in Primary Liver Cancer

The liver is responsible for extremely important functions in the human body. In the liver’s structure, we distinguish between connective tissue (stroma) and parenchyma, the latter of which is formed from the basic structural and functional units of the liver—hepatocytes. There are many factors, that negatively affect the liver cells, contributing to their damage. This may lead to fibrosis, liver failure and, in consequence, primary liver cancer, which is the sixth most commonly diagnosed malignancy and the fourth leading cause of cancer death worldwide. Chemokines are a large family of secreted proteins. Their main role is to direct the recruitment and migration of cells to sites of inflammation or injury. Some authors suggest that these proteins might play a potential role in the development of many malignancies, including primary liver cancer. The aim of this study was to evaluate and summarize the knowledge regarding liver diseases, especially primary liver cancer (HCC) and the participation of chemokines in the development of this malignancy. Chemokines involved in the initiation of this type of tumor belong mainly to the CC and CXC chemokines. Their significant role in the course of hepatocellular carcinoma proves their usefulness in detecting and monitoring the course and treatment in patients with this disease.

Asynchronous electronic consultation between primary care and specialized care proved effective for continuum of care for viraemic hepatitis C patients

INTRODUCTION

It has been proposed that primary care diagnose and treat hepatitis C virus (HCV) infection. However, a care circuit between primary and specialized care based on electronic consultation (EC) can be just as efficient in the micro-elimination of HCV. It is proposed to study characteristics and predictive factors of continuity of care in a circuit between primary and specialized care.

METHODS

From February/2018 to December/2019, all EC between primary and specialized care were evaluated and those due to HCV were identified. Variables for regression analysis and to identify predictors of completing the care cascade were recorded.

RESULTS

From 8098 EC, 138 were performed by 89 (29%) general practitioners over 118 patients (median 50.8 years; 74.6% men) and were related to HCV (1.9%). Ninety-two patients (78%) were diagnosed>6 months ago, and 26.3% met criteria for late presentation. Overall, 105 patients required assessment by the hepatologist, 82% (n=86) presented for the appointment, of which 67.6% (n=71) were viraemic, 98.6% of known. Finally, 61.9% (n=65) started treatment. Late-presenting status was identified as an independent predictor to complete the care cascade (OR 1.93, CI 1.71-1.99, p<0.001).

CONCLUSION

Communication pathway between Primary and Specialized Care based on EC is effective in avoiding significant losses of viraemic patients. However, the referral rate is very low, high in late-stage diagnoses, heterogeneous, and low in new diagnoses. Therefore, early detection strategies for HCV infection in primary care are urgently needed.

A Global Systematic Review of Hepatitis C Elimination Efforts through Micro-Elimination

Microelimination targets specific subpopulations and/or geographic settings for hepatitis C virus (HCV) elimination. This review reports on global HCV microelimination literature published from 2013 to 2020. Data were extracted from publications to report a score based on the four key components defining microelimination. Sustained virologic response (SVR) and treatment initiation proportions were calculated for each manuscript and grouped means of these estimates were compared depending on microelimination score and care setting. A total of 83% of the studies were from high-income settings and mainly included people who use drugs or those incarcerated. Among manuscripts, 18 had "low" microelimination scores, 11 had "high" scores, and the differences in mean proportion who initiated treatment and achieved SVR between low and high score groups were statistically significant. Microelimination can be a useful complementary strategy for driving engagement in HCV treatment and cure. Our analysis suggests that adhering to more of the core microelimination components can improve outcomes. This study is registered with Prospero, registration identification: CRD42020175211.

Treating the Hardest to Treat: Reframing the Hospital Admission as an Opportunity to Initiate Hepatitis C Treatment

BACKGROUND

Chronic hepatitis C (CHC) is traditionally treated in the outpatient setting. Despite the excellent tolerability, shortened treatment duration, and high cure rates of newer direct-acting antivirals (DAAs), many vulnerable patients remain untreated due to issues with linkage to care.

AIMS

This study sought to reframe and establish the hospital admission as a unique opportunity to initiate antiviral treatment for patients with CHC, particularly those with psychosocial or linkage to care issues.

METHODS

Patients with untreated CHC were identified either on the Psychiatry or Med/Surg wards at the Veterans Affairs Palo Alto Health Care System (VAPAHCS). If found to be appropriate for treatment initiation, patients were started on antivirals during their hospitalization and followed closely while inpatient and after discharge to assess for sustained virologic response (SVR), treatment tolerability, and treatment completion.

RESULTS

Overall, 36% (23) of potential treatment candidates were initiated on DAA treatment during their hospitalization. Of these patients, 91.3% had documented treatment completion with an intention-to-treat and modified intention-to-treat SVR rate of 91.3% and 100%, respectively.

CONCLUSIONS

We establish the hospital admission as a valuable opportunity for HCV treatment initiation, yielding excellent treatment outcomes in those who would not otherwise be treated and achieved a modified intention-to-treat response rate of 100%.

Impact of an Accelerated Pretreatment Evaluation on Linkage-to-Care for Hepatitis C-infected Persons Who Inject Drugs

Background:

Historically, hepatitis C virus (HCV) pretreatment evaluation has required multiple visits, frequently resulting in loss to follow-up and a delayed initiation of treatment. New technologies can accelerate this process. We investigated the feasibility of a single-day evaluation program and its impact on evaluation completion, treatment eligibility awareness, and treatment initiation among people who inject drugs (PWIDs).

Methods:

HCV-infected PWID who were unaware if they were eligible for treatment were recruited in a prospective evaluation of an accelerated model of care between 2017 and 2019 and compared to a historical cohort. The patients underwent a medical evaluation, rapid HCV viral load testing, and transient elastography during a single visit, at the end of which they were informed whether they were eligible for treatment. A historical cohort of patients fulfilling the same inclusion criteria and evaluated with the usual standard of care spanning several visits who were examined at the addiction medicine clinic from 2014 to 2016 served as the comparison group.

Results:

The accelerated and historical cohorts included 99 and 76 patients, respectively. The cohorts did not differ significantly by age and gender, but more patients in the historical cohort were undergoing opioid agonist therapy, while more patients in the accelerated cohort injected drugs in the last month. An accelerated evaluation resulted in a higher rate of evaluation completion (100% vs 67.1%; P < .001). Among those eligible for treatment, the proportion of those initiating treatment was similar between the groups (51/64 (79.7%) vs. 26/37 (70.3%); P = .28). The delay in the initiation of treatment was shorter in the accelerated cohort than in the historical cohort (69 (IQR: 49-106) days vs. 219 (IQR: 141-416) days; P < .001).

Conclusions:

Accelerated evaluation enhanced the awareness of eligibility and reduced the time to initiation among eligible patients.

Trial Registration:

This study is registered on www.clinicaltrials.gov (NCT02755402).

Positive predictive value of sustained virologic response 4 weeks posttreatment for achieving sustained virologic response 12 weeks posttreatment in patients receiving glecaprevir/pibrentasvir in Phase 2 and 3 clinical trials

Sustained virologic response at posttreatment Week 12 (SVR12) is the widely accepted efficacy endpoint for direct-acting antiviral agents. Those with hepatitis C virus (HCV) are presenting younger with milder liver disease, potentially reducing need for long-term liver posttreatment monitoring. This analysis aimed to determine the positive predictive value (PPV) of SVR at posttreatment Week 4 (SVR4) for achieving SVR12 in patients with HCV, without cirrhosis or with compensated cirrhosis, receiving glecaprevir/pibrentasvir (G/P) in clinical trials. An integrated dataset from 20 Phase 2 and 3 clinical trials of G/P was evaluated in patients with 8-, 12- or 16-week treatment duration consistent with the current label (label-consistent group), and in all patients regardless of treatment duration consistency with the current label (overall group). Sensitivity analyses handled missing data either by backward imputation or were excluded. SVR4 PPV, negative predictive value (NPV), sensitivity and specificity were calculated for achieving SVR12 in both groups, and by treatment duration in the label-consistent group. SVR was defined as HCV ribonucleic acid 99% in both groups regardless of treatment duration. Not achieving SVR4 had 100% NPV and sensitivity for all groups. SVR4 measure had 79.5% specificity for identifying patients who did not achieve SVR12. Across 20 Phase 2/3 clinical trials of G/P, SVR4 was highly predictive of SVR12. Long-term follow-up to confirm SVR may not be necessary for certain populations of patients with HCV.

Hepatitis C Diagnosis: Simplified Solutions, Predictive Barriers, and Future Promises

The simplification of current hepatitis C diagnostic algorithms and the emergence of digital diagnostic devices will be very crucial to achieving the WHO's set goals of hepatitis C diagnosis (i.e., 90%) by 2030. From the last decade, hepatitis C diagnosis has been revolutionized by the advent and approval of state-of-the-art HCV diagnostic platforms which have been efficiently implemented in high-risk HCV populations in developed nations as well as in some low-to-middle income countries (LMICs) to identify millions of undiagnosed hepatitis C-infected individuals. Point-of-care (POC) rapid diagnostic tests (RDTs; POC-RDTs), RNA reflex testing, hepatitis C self-test assays, and dried blood spot (DBS) sample analysis have been proven their diagnostic worth in real-world clinical experiences both at centralized and decentralized diagnostic settings, in mass hepatitis C screening campaigns, and hard-to-reach aboriginal hepatitis C populations in remote areas. The present review article overviews the significance of current and emerging hepatitis C diagnostic packages to subvert the public health care burden of this 'silent epidemic' worldwide. We also highlight the challenges that remain to be met about the affordability, accessibility, and health system-related barriers to overcome while modulating the hepatitis C care cascade to adopt a 'test and treat' strategy for every hepatitis C-affected individual. We also elaborate some key measures and strategies in terms of policy and progress to be part of hepatitis C care plans to effectively link diagnosis to care cascade for rapid treatment uptake and, consequently, hepatitis C cure.

Village-to-village screening for hepatitis B and C using quantitative HBsAg and anti-HCV testing with reflex HCV core antigen tests in the remote communities of a resource-rich setting: a population-based prospective cohort study

OBJECTIVES

Community-based screening for hepatitis B virus (HBV) and hepatitis C virus (HCV) is essential for hepatitis elimination. This study attempted to increase screening accessibility and efficacy by using alternative tools.

DESIGN

Population-based prospective cohort study.

SETTING

Hepatitis elimination program at Yunlin County, Taiwan.

PARTICIPANTS

All 4552 individuals participated in 60 screening sessions of a community-based HBV and HCV screening project in five rural townships with approximately 95 000 inhabitants in central-western Taiwan.

INTERVENTIONS

To increase accessibility, 60 outreach screening sessions were conducted in 41 disseminative sites. Quantitative HBV surface antigen (qHBsAg) and anti-HCV testing with reflex HCV core antigen (HCV Ag) tests were employed as alternative screening tools.

MAIN OUTCOME MEASURES

Calculate village-specific prevalence of HBsAg, anti-HCV and HCV Ag and establish patient allocation strategies according to levels of qHBsAg HCV Ag and alanine aminotransferase (ALT).

RESULTS

Of 4552 participants, 553, 697 and 290 were positive for HBsAg, anti-HCV and HCV Ag, respectively; 75 of them had both HBsAg and anti-HCV positivity. The average (range) number of participants in each screening session was 98 (31-150). The prevalence rates (range) of HBsAg, anti-HCV and HCV Ag were 12.1% (4.3%-19.4%), 15.3% (2.6%-52.3%) and 6.4% (0%-30.2%), respectively. The HCV Ag positivity rate among anti-HCV-positive participants was 42% (0%-100%). Using cut-off values of >200 IU/mL for qHBsAg, >3 fmol/L for HCV Ag and >40 IU/mL for ALT as criteria for patient referral, we noted an 80.2% reduction in referral burden. Three villages had high anti-HCV prevalences of 52.3%, 53.8% and 63.4% with corresponding viraemic prevalences of 23.2%, 30.1% and 22% and thus constituted newly identified HCV-hyperendemic villages.

CONCLUSION

Outreach hepatitis screening increases accessibility for residents in rural communities. Screening HBV and HCV through qHBsAg and HCV Ag tests provides information concerning viral activities, which might be conducive to precise patient allocation in remote communities.

Current impact of viral hepatitis on liver cancer development: The challenge remains

Chronic infections due to hepatitis B and hepatitis C viruses are responsible for most cases of hepatocellular carcinoma (HCC) worldwide, and this association is likely to remain during the next decade. Moreover, viral hepatitis-related HCC imposes an important burden on public health in terms of disability-adjusted life years. In order to reduce such a burden, some major challenges must be faced. Universal vaccination against hepatitis B virus, especially in the neonatal period, is probably the most relevant primary preventive measure against the development of HCC. Moreover, considering the large adult population already infected with hepatitis B and C viruses, it is also imperative to identify these individuals to ensure their access to treatment. Both hepatitis B and C currently have highly effective therapies, which are able to diminish the risk of development of liver cancer. Finally, it is essential for individuals at high-risk of HCC to be included in surveillance programs, so that tumors are detected at an early stage. Patients with hepatitis B or C and advanced liver fibrosis or cirrhosis benefit from being followed in a surveillance program. As hepatitis B virus is oncogenic and capable of leading to liver cancer even in individuals with early stages of liver fibrosis, other high-risk groups of patients with hepatitis B are also candidates for surveillance. Considerable effort is required concerning these strategies in order to decrease the incidence and the mortality of viral hepatitis-related HCC.

Hepatitis C Micro-Elimination beyond Prison Walls: Navigator-Assisted Test-and-Treat Strategy for Subjects Serving Non-Custodial Sentences

BACKGROUND AND AIMS

The Spanish prison population includes two groups: people in prison and those who are serving non-custodial sentences. The latter has not yet been studied. This study aims to describe this population and the results of a test-and-treat strategy for hepatitis C including a holistic health assessment.

METHOD

This prospective study included all subjects serving non-custodial sentences at the Center for Social Integration. It was assisted by the medical team, a navigator, and a systematic screening of HCV (Hepatitis C Virus) performed by point-of-care tests. All cases with active infection are evaluated using telemedicine by a specialist to prescribe antiviral treatment. The navigator facilitates continuity for medical and social assistance.

RESULTS

The screening rate reached 92.8% (548/590). HCV seroprevalence and viraemia prevalence were 8% (44) and 2.9% (16), respectively. Regarding comorbidities: problems related to drug dependence were detected in 264 (48.2%), suspected serious mental disorder in 44 (8.3%), and previous stay in prison in 122 cases (22.2%). The navigator monitored 59 (15.2%) patients regarding HCV treatment or comorbidities. All patients (10/10) completing 12 weeks follow-up achieved sustained virological response.

CONCLUSIONS

The population serving non-custodial sentences is a challenging group with a high prevalence of HCV infection. Micro-elimination programs using point of care diagnostic tests, telemedicine, and a navigator are necessary in this underserved vulnerable population.

Effectiveness of a Decentralized Hub and Spoke Model for the Treatment of Hepatitis C Virus in a Federally Qualified Health Center

Hepatitis C virus (HCV) is a major cause of cirrhosis, liver cancer, and mortality in the United States. We assessed the effectiveness of decentralized HCV treatment delivered by nurse practitioners (NPs), primary care physicians (PMDs), or an infectious disease physician (ID MD) using direct-acting antivirals in a Federally Qualified Health Center (FQHC) in urban San Diego, CA. We conducted a cross-sectional analysis of 1,261 patients who received treatment from six NPs, 10 PMDs, and one ID MD practicing in 10 clinics between January 2014 and January 2020. Care was delivered based on the Extension for Community Healthcare Outcomes (Project ECHO) model with one hub and nine spokes. HCV was deemed cured if a patient had a sustained virologic response (SVR) after 12 weeks of treatment (SVR12). We evaluated differences in the prevalence of cure between provider types and hub or spoke status using Poisson regression. Patients were 34% Latino, 16% black, 63% were aged >50 years, and 59% were homeless; 53% had advanced fibrosis, 69% had genotype 1, and 5% were coinfected with human immunodeficiency virus. A total of 943 patients achieved SVR12 (96% per protocol and 73% intention to treat). Even after adjustment for demographics, resources, and disease characteristics, the prevalence of cure did not differ between the ID MD and PMDs (prevalence ratio [PR], 1.00; 95% confidence interval [CI], 0.95-1.04) or NPs (PR, 1.01; 95% CI, 0.96-1.05). Similarly, there were no differences between the hub and spokes (PR, 1.01; 95% CI, 0.98-1.04). Conclusion: Among a low-income and majority homeless cohort of patients at urban FQHC clinics, HCV treatment administered by nonspecialist providers was not inferior to that provided by a specialist.
