Abstract
Introduction Progress towards achieving hepatitis C virus (HCV) elimination in Florida has been hampered by barriers to screening, linkage to care, and treatment. This study aims to describe the HCV care cascade and patient characteristics in Florida. Methods This analysis combined HCV-related laboratory data and patient characteristics from two, large US laboratory datasets that included individuals tested for HCV antibody (Ab) and HCV ribonucleic acid (RNA) viral load between January 2015 and December 2019. A decline in sequential HCV RNA viral loads was used to impute HCV treatment. Machine-learning algorithms were used to identify cured patients. The actual number of individuals with HCV Ab screening, and the number and percentage of persons who were HCV RNA-positive and treated, were calculated. Results The number of persons in Florida diagnosed as HCV RNA-positive was 31,659 in 2019. The number of individuals HCV Ab screened in 2019 was 1,024,379, an increase of 82.5% from 2015. The percentage of HCV Ab-positive individuals was 4.1%, demonstrating a 16.2% decrease from 2015. The percentage of HCV RNA-positive patients who were treated was 27.0%, a 10.5% decrease from 2015 to 2019. Conclusion An Ab positivity rate > 4-times higher than national estimates with increased screening among baby boomers, but decreased screening among younger individuals, suggests risk-based screening is still common practice in Florida, despite universal screening recommendations. Public health efforts to decrease barriers to screening, linkage to care, and treatment are needed to reduce the burden of HCV in Florida and to ensure progress toward virus elimination.

Abstract
Introduction Hepatitis C virus (HCV) is the most common bloodborne chronic infection in the US. Following approval of highly effective, direct-acting antivirals in 2014, the diagnostic and treatment rates for HCV infection in the US have evolved. This study assessed the number of individuals with HCV screening or diagnostic testing and the clinical characteristics and treatment of HCV-infected individuals between 2017 and 2019. Methods Individuals screened for HCV antibody and/or tested for HCV ribonucleic acid (RNA) from 2017 to 2019 by two large US laboratory companies were included in this analysis. Clinical characteristics, such as HCV genotype, fibrosis stage, HIV coinfection and demographics, were assessed in HCV RNA-positive individuals. HCV treatment and subsequent achievement of sustained virologic response were imputed using data-driven algorithms based on successive viral load decline and negativity. Results From 2017 to 2019, the number of individuals tested for HCV antibody increased by 5.7%, from 7,580,303 in 2017 to 8,009,081 in 2019. The percentage of individuals tested who were HCV antibody positive was stable, ranging from 5.0% in 2017 to 4.9% in 2018 and 2019. The number of HCV RNA-positive individuals decreased by 5.0% from 382,500 in 2017 to 363,532 in 2019. Of HCV RNA-positive individuals, the proportions with genotype (GT) 3 and minimal fibrosis increased over time; proportions of individuals aged < 40 years increased, while the proportion aged 50 to 59 years decreased. Treatment rates increased from 23.4% in 2017 to 26.8% in 2019. Conclusions The percentage of HCV antibody-positive individuals remained stable from 2017 to 2019. The number of individuals tested HCV RNA positive decreased over the years. Demographics shifted toward a younger population with less fibrosis and higher rates of GT3. More than 70% of diagnosed individuals were not treated during this interval, highlighting a need for unfettered access to treatment.

Abstract
The number of patients diagnosed with hepatitis C virus (HCV) is markedly higher than the number initiating treatment indicating gaps in the care cascade, likely centred around reaching at-risk populations. Understanding changing characteristics of patients with HCV allows for targeted programs that increase linkage to care. We investigated changes in demographic and clinical characteristics of patients registered in the German Hepatitis C-Registry (DHC-R) from 1 January 2014 to 31 December 2019. The DHC-R is an ongoing, noninterventional, multicentre, prospective, observational cohort registry including 327 German centres. Patient characteristics were analysed over time in 7 phases for all patients completing a screening visit. Overall, 14,357 patients were enrolled. The percentage of treatment-naïve/non-cirrhotic patients increased from 34.4% in phase 1 (1 January-31 December 2014) to 68.2% in phase 7 (1 August-31 December 2019). The proportion of migrants, alcohol users, people who inject drugs, and those receiving opiate substitution therapy increased in later registry phases. Most patients (60.1%) were receiving comedication at baseline. The most prescribed comedications were drugs used to treat opioid dependence which increased from 9.2% in phase 1 to 24.0% in phase 7. The patients' mean age decreased from 52.3 years in phase 1 to 48.7 years in phase 7. From 2014 to 2019, the proportion of at-risk patients enrolling in the registry increased. To eliminate viral hepatitis as a major public health threat, a continued commitment to engaging underserved populations into the HCV care cascade is needed.

Abstract
Glecaprevir/pibrentasvir is a pangenotypic direct-acting antiviral regimen approved for treating chronic hepatitis C virus. Real-world use of protease-inhibitor-containing regimens requires further evaluation in patients with cirrhosis. We evaluated the real-world safety and effectiveness of glecaprevir/pibrentasvir in patients with cirrhosis from the German Hepatitis C-Registry who initiated treatment between 2 August 2017 and 30 June 2019. Overall, 131 patients received 12-week (on-label) treatment and 51 received 8-week (off-label) treatment. No patient discontinued treatment due to adverse events. Four patients had serious adverse events; none were considered related to glecaprevir/pibrentasvir. Two patients had total bilirubin > 5 × upper limit of normal (ULN) during treatment. Three patients had alanine aminotransferase and three patients had aspartate aminotransferase > 3 × ULN. Rates of sustained virologic response were 100% (86/86) for 86 patients with available data. Glecaprevir/pibrentasvir treatment was well-tolerated and highly effective in patients with chronic hepatitis C and cirrhosis in real-world practice.

Abstract
BACKGROUND Rates of early syphilis in US women are steadily increasing, but predictors of infection in this group are not clearly defined. METHODS This retrospective analysis focused on women enrolled in the US CFAR Network of Integrated Clinical Systems cohort between January 2005 and December 2016 with syphilis testing performed. The primary outcome of incident syphilis infection was defined serologically as a newly positive test with positive confirmatory testing after a negative test or a 2-dilution increase in rapid plasma regain titer. Infection rates were calculated for each woman-year in care with testing. Predictors of syphilis were sought among sociodemographics, clinical information, and self-reported behaviors. Multivariable logistic regression models were created; a subgroup analysis assessed predictors in women of reproductive age. RESULTS The annual rate of incident syphilis among 4416 women engaged in human immunodeficiency virus (HIV) care and tested during the 12-year study period was 760/100 000 person-years. Independent predictors of infection were injection drug use as a risk factor for HIV acquisition (aOR, 2.2; 95% CI, 1.3-3.9), hepatitis C infection (aOR, 1.9; 95% CI, 1.1-3.4), black race (aOR, 2.2; 95% CI, 1.3-3.7 compared with white race), and more recent entry to care (since 2005 compared with 1994-2004). Predictors were similar in women aged 18-49. CONCLUSIONS Syphilis infection is common among US women in HIV care. Syphilis screening and prevention efforts should focus on women reporting drug use and with hepatitis C coinfection. Future studies should identify specific behaviors that mediate syphilis acquisition risk in women who use drugs.

The ten-year (2006-2015) experience from a population-based cancer registry in Southern Italy. BMC Cancer 2021; 21:307. [PMID: 33761907 PMCID: PMC7988914 DOI: 10.1186/s12885-021-07935-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Accepted: 02/18/2021] [Indexed: 11/23/2022] Open
Abstract
Background Hepatocellular carcinoma (HCC) is the most frequent primary invasive cancer of the liver. During the last decade, the epidemiology of HCC has been continuously changing in developed countries, due to more effective primary prevention and to successful treatment of virus-related liver diseases. The study aims to examine survival by level of access to care in patients with HCC, for all patients combined and by age. Methods We included 2018 adult patients (15–99 years) diagnosed with a primary liver tumour, registered in the Palermo Province Cancer Registry during 2006–2015, and followed-up to 30 October 2019. We obtained a proxy measure of access to care by linking each record to the Hospital Discharge Records and the Ambulatory Discharge Records. We estimated net survival up to 5 years after diagnosis by access to care (“easy access to care” versus “poor access to care”), using the Pohar-Perme estimator. Estimates were age-standardised using International Cancer Survival Standard (ICSS) weights. We also examined survival by access to care and age (15–64, 65–74 and ≥ 75 years). Results Among the 2018 patients, 62.4% were morphologically verified and 37.6% clinically diagnosed. Morphologically verified tumours were more frequent in patients aged 65–74 years (41.6%), while tumours diagnosed clinically were more frequent in patients aged 75 years or over (50.2%). During 2006–2015, age-standardised net survival was higher among HCC patients with “easy access to care” than in those with “poor access to care” (68% vs. 48% at 1 year, 29% vs. 11% at 5 years; p < 0.0001). Net survival up to 5 years was higher for patients with “easy access to care” in each age group (p < 0.0001). Moreover, survival increased slightly for patients with easier access to care, while it remained relatively stable for patients with poor access to care. Conclusions During 2006–2015, 5-year survival was higher for HCC patients with easier access to care, probably reflecting progressive improvement in the effectiveness of health care services offered to these patients. Our linkage algorithm could provide valuable evidence to support healthcare decision-making in the context of the evolving epidemiology of hepatocellular carcinoma.

Abstract
BACKGROUND Hepatitis C virus (HCV) epidemiology has shifted from the baby-boomer generation to young women of childbearing age. The health benefits and cost-effectiveness (CE) of screening pregnant women remain controversial. AIM To systematically review published studies evaluating the CE of screening pregnant women for HCV in the era of direct-acting antivirals (DAAs). MATERIALS AND METHODS We conducted a systematic literature search of CE studies evaluating the costs and benefits of screening pregnant women for HCV. Pertinent information including antiviral agent, drug costs, incremental cost-effective ratio (ICER), and infant care was collected. The authors' definition of the threshold price at which screening was deemed CE was also recorded. The quality of studies was assessed using the Consolidated Health Economic Evaluation Reports Standards (CHEERS) checklist. RESULTS We identified 5 studies that evaluated the ICER of screening pregnant women for HCV. Of these, 2 utilized all oral DAAs, with universal screening CE. The ICER of these 2 studies was $3000 and $41,000 per quality of life-years gained. The remaining studies were interferon-based regimens. Most studies did not include screening of infants. CONCLUSIONS Universally screening pregnant women for HCV was CE in studies that utilized oral DAAs. Most pharmacoeconomic studies failed to incorporate the impact of vertical transmission on infants.

Abstract
Introduction Although hepatitis C virus (HCV) infection remains a major clinical, economic, and societal burden, the development of curative antiviral therapy may accelerate the path toward elimination. This analysis assessed the progress of United States (US) states towards achieving the World Health Organization’s (WHO) 2030 HCV elimination targets for incidence, mortality, diagnosis, and treatment. Methods A previously published Markov model was used to simulate HCV progression over time to estimate the path to HCV elimination in each state based on prevalence, annual treatment, and diagnosis inputs from two large US laboratory datasets from January 2013 to December 2017. State-specific fibrosis stage restrictions on treatment in 2017 were included. The model estimated the year individual states would meet the WHO targets for diagnosing 90% of the HCV-infected population, treating 80% of the eligible population, reducing new HCV infections by 80%, and reducing HCV-related deaths by 65%. The minimum number of annual treatments needed between 2020 and 2030 to achieve the WHO treatment target was also calculated. Results Overall, the USA is projected to achieve HCV elimination by 2037, with individual targets related to mortality, diagnosis, treatment, and incidence being achieved by 2020, 2027, 2033, and 2037, respectively. Three states (Connecticut, South Carolina, and Washington) are on track to meet all four elimination targets by 2030, and 18 states are not expected to meet these targets before 2040. The estimated annual number of treatments required during 2020–2030 nationally to reach the WHO treatment target is 173,514. Conclusion With the exception of three states, the USA is not on target to meet the WHO 2030 elimination targets and 35% are off track by 10 years or more. Strategies must be implemented to reduce overall prevalence by preventing new infections, increasing rates of screening, improving linkage to care, and implementing unfettered access to curative therapy.

Abstract
In 2016, the World Health Organization (WHO) set a target for eliminating viral hepatitis as a major public health threat by 2030. However, while today's highly effective and well-tolerated pangenotypic direct-acting antiviral regimens have maximized simplification of hepatitis C virus (HCV) treatment, there remain a plethora of barriers to HCV screening, diagnosis, and linkage to care. As of 2017, only 19% of the estimated 71 million individuals living with chronic HCV worldwide were diagnosed and in 2015 to 2016, only 21% of diagnosed individuals had accessed treatment. Simplification and decentralization of the HCV care cascade would bolster patient engagement and support the considerable scale-up needed to achieve WHO targets. Recent developments in HCV screening and diagnosis, together with reduced pretreatment assessment and on-treatment monitoring requirements, can further streamline the care continuum, ensuring patients are linked to care quickly and earlier in the disease course, and minimize clinic visits.

Abstract
INTRODUCTION More than 70 million people are estimated to be infected with hepatitis C virus globally. Glecaprevir/pibrentasvir is a widely used treatment and has recently been approved for an 8-week regimen for treatment-naïve patients with compensated cirrhosis in Europe and the USA, who would previously have received glecaprevir/pibrentasvir for 12 weeks. This label update was based on the EXPEDITION-8 study, which included 343 treatment-naïve patients with compensated cirrhosis. However, there is currently a lack of similarly large-scale real-world studies of the 8-week glecaprevir/pibrentasvir regimen in this population. METHODS This summary of seven separate smaller real-world studies aims to validate the results seen in EXPEDITION-8 and provide an up-to-date real-world reference for clinicians making treatment decisions for patients with compensated cirrhosis (Child-Pugh A) who may benefit from a shorter-duration therapy with glecaprevir/pibrentasvir. The newly emerging real-world effectiveness data on treatment-naïve patients with compensated cirrhosis treated with 8 weeks of glecaprevir/pibrentasvir help to understand where further research is needed to support patients with hepatitis C virus. RESULTS Across all seven studies, glecaprevir/pibrentasvir showed high effectiveness with an average sustained virologic response rate of 98.1%, similar to that found in a clinical trial setting (99.7%). Only one patient (0.5%) experienced virologic failure and treatment was well tolerated. CONCLUSION Expanding the number of patients eligible for the shortened treatment duration will potentially increase treatment initiation and completion, particularly in underserved populations, contributing to the elimination of hepatitis C virus.

Abstract
Infection with hepatitis C virus (HCV) is pervasive throughout the United States of America as we fight the ongoing urban and rural opioid epidemics and rising rates of fatal and non-fatal overdoses. While risk factors for incident HCV abound, our country and the State of Delaware have increasing access to highly effective, short-course, curative HCV treatments. Despite unprecedented medical advances for HCV, as well as expanded HCV screening guidelines calling for universal adult HCV screening and screening during every pregnancy, the epidemiology of HCV at the national and statewide levels continues to be lacking. In attempting to gather, interpret, and present the highest quality available data, we conclude that HCV remains a pressing public and individual health concern for Delawareans, and our nation at large. We urge stakeholders in Delaware to make concerted efforts to fill in the many remaining gaps of HCV epidemiology in order to better inform public health resource allocation, educate the public and healthcare professionals regarding viral hepatitis, and ultimately improve the HCV care continuum, spanning from increasing rates of universal HCV screening and diagnosis to linkage to care to treatment initiation all the way to cure and beyond.

Real-world effectiveness and safety of glecaprevir/pibrentasvir for the treatment of patients with chronic HCV infection: A meta-analysis. J Hepatol 2020; 72:1112-1121. [PMID: 32061651 DOI: 10.1016/j.jhep.2020.01.025] [Citation(s) in RCA: 57] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2019] [Revised: 12/19/2019] [Accepted: 01/15/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Glecaprevir/pibrentasvir is approved for treating adults infected with HCV genotypes 1-6. In clinical trials, glecaprevir/pibrentasvir was associated with high rates of sustained virologic response at post-treatment week 12 (SVR12) and was well tolerated. A systematic review and meta-analysis of the real-world effectiveness and safety of glecaprevir/pibrentasvir were undertaken. METHODS Real-world studies reporting SVR12 in adults with HCV infection (n ≥20) treated with glecaprevir/pibrentasvir were identified in journal publications from January 1, 2017, to February 25, 2019, and congress presentations through April 14, 2019. Random-effects meta-analysis was used to determine SVR12 rates using data from ≥2 cohorts; intention-to-treat (ITT) analyses included patients treated with glecaprevir/pibrentasvir who had SVR12 data available, discontinued early, or were lost to follow-up; modified ITT (mITT) analyses excluded those with non-virologic failure. Naïve pooling was used to calculate adverse event (AE) rates. RESULTS Overall, 12,531 adults were treated with glecaprevir/pibrentasvir (18 cohorts). Of patients with post-treatment week 12 data, SVR12 rates were 96.7% (95% CI 95.4-98.1) in the ITT population (n = 8,583, 15 cohorts) and 98.1% (95% CI 97.1-99.2) in the mITT population (n = 7,001, 14 cohorts). SVR12 rates were ≥95% across subgroups (HCV genotype, cirrhosis status, treatment history, treatment duration, on-label treatment, and subgroups of interest). AEs were reported in 17.7% (1,271/7,199) of patients (8 cohorts). Serious AEs were reported in 1.0% (55/5,522) of patients (6 cohorts). The most frequent AEs were pruritus, fatigue, and headache. AE-related treatment discontinuations were reported in 0.6% (33/5,595) of patients (6 cohorts). CONCLUSIONS Consistent with clinical trials, real-world evidence indicates that glecaprevir/pibrentasvir is a well-tolerated and highly effective pangenotypic treatment for a broad range of HCV-infected patients. LAY SUMMARY It is important to assess treatments for hepatitis C virus (HCV) in the real world, as patient populations tend to be more diverse and potentially less adherent to treatment compared to those in clinical trials. Results from 18 studies performed in real-world clinics were pooled and analyzed to investigate the effectiveness and safety of a direct-acting antiviral combination (glecaprevir/pibrentasvir) in routine clinical practice. This analysis showed that glecaprevir/pibrentasvir is highly effective and well tolerated across all HCV genotypes and patient groups studied. It also showed that results seen in the real world are similar to the results seen in clinical trials, even in patients historically considered more challenging to treat.

Abstract
Hepatitis B virus (HBV) causes a potentially life-threatening liver infection that frequently results in life-long chronic infection. HBV is responsible for 887,000 deaths each year, most resulting from chronic liver diseases and hepatocellular carcinoma. Presently, there are 250 million chronic HBV carriers worldwide who are at a high risk for developing cirrhosis and hepatocellular carcinoma (HCC). HCC is the most common type of liver cancer with a strong association with HBV infection. HBV transmission through blood transfusions and perinatal transfer from infected mother to child have been common routes of infection. In the present study, we describe the development of a synthetic DNA plasmid encoding an anti-HBV human monoclonal antibody specific for the common “a determinant region” of HBsAg of hepatitis B virus and demonstrate the ability of this platform at directing in vivo antibody expression. In vivo delivery of this DNA encoded monoclonal antibody (DMAb) plasmid in mice resulted in expression of human IgG over a period of one month following a single injection. Serum antibody was found to recognize the relevant conformational epitope from plasma purified native HBsAg as well as bound HBV in HepG2.2.15 cells. The serum DMAb efficiently neutralized HBV and prevented infection of HepaRG cells in vitro. Additional study of these HBV-DMAb as a possible therapy or immunoprophylaxis for HBV infection is warranted.

Effectiveness of 8-Week Glecaprevir/Pibrentasvir for Treatment-Naïve, Compensated Cirrhotic Patients with Chronic Hepatitis C Infection. Adv Ther 2020; 37:2267-2274. [PMID: 32279176 PMCID: PMC7467488 DOI: 10.1007/s12325-020-01301-5] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2020] [Indexed: 12/16/2022]
Abstract
Introduction Glecaprevir/pibrentasvir (G/P) was approved on 26 September 2019 by the US Food and Drug Administration for 8-week duration in treatment-naïve (TN) hepatitis C virus (HCV)-infected patients with compensated cirrhosis (CC). Evidence from the EXPEDITION-8 study demonstrated that 8 weeks of G/P achieved a 98% intent-to-treat (ITT) sustained virologic response rate 12 weeks post treatment (SVR12) in 343 TN/CC patients. The aim of this study is to demonstrate the first US real-world effectiveness of G/P 8-week treatment in genotype 1–6 TN/CC HCV patients. Methods Data from 73 TN/CC patients who initiated 8 weeks of G/P treatment between August 2017 and November 2018 were collected electronically from providers and specialty pharmacies of the Trio Health network and analyzed. Cirrhosis was determined by FIB-4 > 5.2 or was physician reported. The primary outcome was Per Protocol (PP) SVR12. Results The majority (60%) of patients were male, with (mean values): age 59 years, body mass index (BMI) of 30, aspartate aminotransferase (AST) 105, and alanine aminotransferase (ALT) 101 IU/ml. HCV genotypes (GT) were: GT1 81% (59/73), GT2 10% (7/73), GT3 5% (4/73), GT4 3% (2/73), and GT6 1% (1/73). Eight percent (6/73) of patients had concurrent proton pump inhibitor (PPI) use, and 15% (11/72) had a baseline viral load > 6 MM IU/ml. Zero patients discontinued, two patients were reported as lost to follow-up, and there was one virologic failure. PP sustained virologic response at 12 weeks (SVR12) rate was 99% (70/71), and the intent-to-treat (ITT) SVR12 rate was 96% (70/73). Conclusions Early real-world experience indicates high effectiveness of the 8-week G/P regimen in a diverse treatment-naïve, compensated cirrhotic US population.

Abstract
BACKGROUND & AIMS Eight-week glecaprevir/pibrentasvir leads to high rates of sustained virological response at post-treatment week 12 (SVR12) across HCV genotypes (GT) 1-6 in treatment-naïve patients without cirrhosis. We evaluated glecaprevir/pibrentasvir once daily for 8 weeks in treatment-naïve patients with compensated cirrhosis. METHODS EXPEDITION-8 was a single-arm, multicenter, phase IIIb trial. The primary and key secondary efficacy analyses were to compare the lower bound of the 95% CI of the SVR12 rate in i) patients with GT1,2,4-6 in the per protocol (PP) population, ii) patients with GT1,2,4-6 in the intention-to-treat (ITT) population, iii) patients with GT1-6 in the PP population, and iv) patients with GT1-6 in the ITT population, to pre-defined efficacy thresholds based on historical SVR12 rates for 12 weeks of glecaprevir/pibrentasvir in the same populations. Safety was also assessed. RESULTS A total of 343 patients were enrolled. Most patients were male (63%), white (83%), and had GT1 (67%). The SVR12 rate in patients with GT1-6 was 99.7% (n/N = 334/335; 95%CI 98.3-99.9) in the PP population and 97.7% (n/N = 335/343; 95% CI 96.1-99.3) in the ITT population. All primary and key secondary efficacy analyses were achieved. One patient (GT3a) experienced relapse (0.3%) at post-treatment week 4. Common adverse events (≥5%) were fatigue (9%), pruritus (8%), headache (8%), and nausea (6%). Serious adverse events (none related) occurred in 2% of patients. No adverse event led to study drug discontinuation. Clinically significant laboratory abnormalities were infrequent. CONCLUSIONS Eight-week glecaprevir/pibrentasvir was well tolerated and led to a similarly high SVR12 rate as the 12-week regimen in treatment-naïve patients with chronic HCV GT1-6 infection and compensated cirrhosis. TRIAL REGISTRATION ClinicalTrials.gov, NCT03089944. LAY SUMMARY This study was the first to evaluate an 8-week direct-acting antiviral (DAA) regimen active against all major types of hepatitis C virus (HCV) in untreated patients with compensated cirrhosis. High virological cure rates were achieved with glecaprevir/pibrentasvir across HCV genotypes 1-6, and these high cure rates did not depend on any patient or viral characteristics present before treatment. This may simplify care and allow non-specialist healthcare professionals to treat these patients, contributing to global efforts to eliminate HCV.

Abstract
BACKGROUND Hepatitis C virus (HCV) disproportionately affects disadvantaged communities. OBJECTIVE To examine processes and outcomes of Screen, Treat, Or Prevent Hepatocellular Carcinoma (STOP HCC), a multicomponent intervention for HCV screening and care in safety-net primary care practices. DESIGN Mixed-methods retrospective analysis. SETTING 5 federally qualified health centers (FQHCs) and 1 family medicine residency program serving low-income communities in diverse locations with largely Hispanic populations. PATIENTS Persons born in 1945 through 1965 (baby boomers) who had never been tested for HCV and were followed through May 2018. INTERVENTION The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) model guided implementation and evaluation. Test costs were covered for uninsured patients. MEASUREMENTS All practices tested patients for anti-HCV antibody (anti-HCV) and HCV RNA. For uninsured patients with chronic HCV in 4 practices, quantitative data also enabled assessment of HCV staging, specialist teleconsultation, direct-acting antiviral (DAA) treatment, and sustained virologic response (SVR). Implementation fidelity and adaptation were assessed qualitatively. RESULTS Anti-HCV screening was done in 13 334 of 27 700 baby boomers (48.1%, varying by practice from 19.8% to 71.3%). Of 695 anti-HCV-positive patients, HCV RNA was tested in 520 (74.8%; 48.9% to 92.9% by practice), and 349 persons (2.6% of those screened) were diagnosed with chronic HCV. In 4 FQHCs, 174 (84.9%) of 205 uninsured patients with chronic HCV had disease staging, 145 (70.7%) had teleconsultation review, 119 (58.0%) were recommended to start DAA therapy, 82 (40.0%) initiated free DAA therapy, 74 (36.1%) completed therapy (27.8% to 60.0% by practice), and 70 (94.6% of DAA completers) achieved SVR. Implementation was promoted by multilevel practice engagement, patient navigation, and anti-HCV screening with reflex HCV RNA testing. LIMITATION No control practices were included, and data were missing for some variables. CONCLUSION Despite a similar framework for STOP HCC implementation, performance varied widely across safety-net practices, which may reflect practice engagement as well as infrastructure or cost challenges beyond practice control.

The change in the nationwide seroprevalence of hepatitis C virus and the status of linkage to care in South Korea from 2009 to 2015. Hepatol Int 2019; 13:599-608.

Abstract
BACKGROUND Hepatitis C virus (HCV) requires epidemiological monitoring to estimate its disease burden and to develop countermeasures. This study aimed to investigate the difference between the 2015 and 2009 nationwide anti-HCV seroprevalence and to determine linkage to care estimates in South Korea. METHODS A total 268,422 examinees ≥ 20 years old were included in 2015 from 33 medical institutions nationwide. Electronically extracted data were retrospectively analyzed to calculate the age-, sex-, and area-adjusted anti-HCV prevalence. Seroprevalence in 2015 was measured using the same method as that in 2009. For anti-HCV-positive subjects, medical records were reviewed to see whether HCV RNA testing or antiviral treatment was performed. RESULTS Adjusted anti-HCV prevalence was 0.60% (95% confidence interval, 0.57-0.63) based on general Korean population in 2015. It showed an increasing trend according to age; 0.23% in thirties, 0.38% in forties, 0.63% in fifties, 1.08% in sixties, and 1.65% in those aged ≥ 70 years. From 2009 to 2015, the adjusted anti-HCV prevalence decreased by 30%, with odds ratio of 0.70 (95% CI 0.70-0.71). There was significant intranational regional variation and changing pattern of seroprevalence. Among 1359 anti-HCV-positive subjects, HCV RNA test was performed in 60% and 25.4% had positivity. Treatment-initiated and cured rates in 2015 were 18.5% and 10.9%, respectively. CONCLUSIONS Anti-HCV prevalence in South Korea was 0.6% in 2015, showing a 30% decrease from that in 2009. Although the HCV RNA testing rate was increased since 2009, this remains suboptimal. Moreover, the treatment uptake rate should be improved in South Korea.

Abstract
Chronic hepatitis C viral (HCV) infection continues to carry a high burden of disease despite recent and emerging advancements in treatment. The persistently high prevalence of HCV is attributed to the rising opioid epidemic, with a history of injection drug use as the primary risk factor for infection. As a result, the epidemiology of HCV-infected individuals is changing. Previously a disease of "Baby Boomers," males, and non-Hispanic blacks, the new generation of patients with HCV includes younger adults from 20 to 39 years of age, both men and women similarly represented, and non-Hispanic whites. Shifting trends in these demographics may be attributed to the use of injection drugs, which also has suggested impact on fibrosis progression in infected individuals. Awareness of the changing face of HCV is necessary to expand and revise recommendations regarding screening, outreach, and care engagement of infected individuals, in order to best identify patients at-risk for infection.

Safety and efficacy of glecaprevir/pibrentasvir in patients with chronic hepatitis C genotypes 1-6 receiving opioid substitution therapy. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2019; 66:73-79. [PMID: 30735896 DOI: 10.1016/j.drugpo.2019.01.011] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2018] [Revised: 12/13/2018] [Accepted: 01/07/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUND International guidelines recommend treatment of hepatitis C virus (HCV) infection in people who inject drugs (PWID), including those on opioid substitution therapy (OST). The pangenotypic combination of glecaprevir and pibrentasvir has shown high sustained virologic response at post-treatment Week 12 (SVR12) in clinical trials. Herein, we evaluate the safety and efficacy of glecaprevir/pibrentasvir in patients receiving OST. METHODS Pooled data from patients with HCV genotypes 1-6 who were treated with glecaprevir/pibrentasvir for 8, 12, or 16 weeks in eight Phase 2 and 3 trials were categorized by use of OST. Treatment completion, treatment adherence, SVR12, adverse events (AEs), and laboratory abnormalities were evaluated for patients receiving and not receiving OST. RESULTS Among 2256 patients, 157 (7%) were receiving OST. Compared with patients not receiving OST, OST patients were younger (mean age, 46.8 vs 52.8 years), male (69% vs 54%), white (93% vs 80%), HCV treatment-naïve (86% vs 72%), had HCV genotype 3 (60% vs 26%), and had a history of depression or bipolar disorder (43% vs 19%). Most patients completed (OST: 98% [n/N = 154/157]; non-OST: 99% [n/N = 2070/2099]) and were adherent (received ≥90% of study drug doses) to glecaprevir/pibrentasvir treatment (OST: 98% [n/N = 121/123]; non-OST: 99% [n/N = 1884/1905] among patients with available data). In the intention-to-treat population, SVR12 rates in OST and non-OST patients were 96.2% (n/N = 151/157; 95% CI 93.2-99.2) and 97.9% (n/N = 2055/2099; 95% CI 97.3-98.5), respectively. For OST patients, reasons for nonresponse included virologic relapse (<1%; n = 1), premature study drug discontinuation (<1%; n = 1), and loss to follow-up (3%; n = 4). AEs occurring in ≥10% of OST patients were headache, fatigue, and nausea. Drug-related serious AEs, AEs leading to study drug discontinuation, and Grade 3 or higher laboratory abnormalities were infrequent in both groups (<1%). No HCV reinfections occurred through post-treatment Week 12. CONCLUSION Glecaprevir/pibrentasvir is highly efficacious and well tolerated in HCV-infected patients receiving OST.

Abstract
IMPORTANCE Infection with hepatitis C virus (HCV) is a major cause of morbidity and mortality in the United States, and incidence has increased rapidly in recent years, likely owing to increased injection drug use. Current estimates of prevalence at the state level are needed to guide prevention and care efforts but are not available through existing disease surveillance systems. OBJECTIVE To estimate the prevalence of current HCV infection among adults in each US state and the District of Columbia during the years 2013 to 2016. DESIGN, SETTING, AND PARTICIPANTS This survey study used a statistical model to allocate nationally representative HCV prevalence from the National Health and Nutrition Examination Survey (NHANES) according to the spatial demographics and distributions of HCV mortality and narcotic overdose mortality in all National Vital Statistics System death records from 1999 to 2016. Additional literature review and analyses estimated state-level HCV infections among populations not included in the National Health and Nutrition Examination Survey sampling frame. EXPOSURES State, accounting for birth cohort, biological sex, race/ethnicity, federal poverty level, and year. MAIN OUTCOMES AND MEASURES State-level prevalence estimates of current HCV RNA. RESULTS In this study, the estimated national prevalence of HCV from 2013 to 2016 was 0.84% (95% CI, 0.75%-0.96%) among adults in the noninstitutionalized US population represented in the NHANES sampling frame, corresponding to 2 035 100 (95% CI, 1 803 600-2 318 000) persons with current infection; accounting for populations not included in NHANES, there were 231 600 additional persons with HCV, adjusting prevalence to 0.93%. Nine states contained 51.9% of all persons living with HCV infection (California [318 900], Texas [202 500], Florida [151 000], New York [116 000], Pennsylvania [93 900], Ohio [89 600], Michigan [69 100], Tennessee [69 100], and North Carolina [66 400]); 5 of these states were in Appalachia. Jurisdiction-level median (range) HCV RNA prevalence was 0.88% (0.45%-2.34%). Of 13 states in the western United States, 10 were above this median. Three of 10 states with the highest HCV prevalence were in Appalachia. CONCLUSIONS AND RELEVANCE Using extensive national survey and vital statistics data from an 18-year period, this study found higher prevalence of HCV in the West and Appalachian states for 2013 to 2016 compared with other areas. These estimates can guide state prevention and treatment efforts.
