Chronic infection with hepatitis C virus (HCV) is a leading cause of end-stage liver disease and is the most common indication for liver transplantation in the United States. Because of shared risk factors, individuals living with HIV infection are disproportionately affected by HCV. Moreover, co-infection with HIV accelerates the natural history of chronic HCV infection, increasing the risk of cirrhosis, hepatocellular carcinoma, hepatic decompensation, and death. Highly effective medications such as direct-acting antivirals (DAA) to cure HCV are now available and have the potential to profoundly improve the health of HIV-HCV-co-infected individuals. However, addressing the many gaps in the HCV care cascade is necessary to fully achieve the benefits of these drugs. This chapter reviews the natural history of HIV-HCV co-infection, the psychiatric comorbidities associated with HCV infection, the evolution of HCV treatment, and the barriers to care that HIV-HCV-co-infected individuals continue to face.

Background Coadministration of direct-acting antivirals (DAAs) for chronic hepatitis C virus (HCV) infection and first generation anticonvulsants is currently not recommended due to a drug-drug interaction that could potentially lead to subtherapeutic DAA levels and subsequent treatment failure. Currently, there is limited data evaluating this interaction and timely treatment of HCV infection with DAAs is imperative to prevent liver-related morbidity and mortality. Methods A retrospective case series evaluating clinical cure of chronic HCV infection, defined as sustained virologic response (SVR) 12 weeks after completion of DAA therapy, in patients from three inner-city clinics who remained on first generation anticonvulsants during the treatment course. Results A total of five patients received standard dose DAAs for treatment of chronic HCV infection while being maintained on first generation anticonvulsants. The most common HCV genotype was 1a (80%), followed by 1b (20%). The majority of patients were treated with glecaprevir/pibrentasvir (80%) for eight weeks and one patient was treated with ledipasvir/sofosbuvir for 12 weeks. Anticonvulsant regimens consisted of carbamazepine, phenytoin, phenytoin plus phenobarbital, phenytoin plus levetiracetam, and phenobarbital plus lacosamide. All five patients achieved sustained virologic response (SVR) despite this drug-drug interaction. Conclusion Although every effort to prevent concomitant use of DAAs and potent inducers should be made, clinical cure may still be achieved in patients whom cannot avoid this coadministration.

Abstract Background Hepatitis C virus (HCV) elimination by 2030, as targeted by the World Health Organization (WHO), requires that 90% of people with chronic infection be diagnosed and 80% treated. We estimated the cascade of care (CoC) for chronic HCV infection in mainland France in 2011 and 2016, before and after the introduction of direct-acting antivirals (DAAs). Methods The numbers of people (1) with chronic HCV infection, (2) aware of their infection, (3) receiving care for HCV and (4) on antiviral treatment, were estimated for 2011 and 2016. Estimates for 1) and 2) were based on modelling studies for 2011 and on a virological sub-study nested in a national cross-sectional survey among the general population for 2016. Estimates for 3) and 4) were made using the National Health Data System. Results Between 2011 and 2016, the number of people with chronic HCV infection decreased by 31%, from 192,700 (95% Credibility interval: 150,900-246,100) to 133,500 (95% Confidence interval: 56,900-312,600). The proportion of people aware of their infection rose from 57.7 to 80.6%. The number of people receiving care for HCV increased by 22.5% (representing 25.7% of those infected in 2016), while the number of people on treatment increased by 24.6% (representing 12.1% of those infected in 2016). Conclusions This study suggests that DAAs substantially impact CoC. However, access to care and treatment for infected people remained insufficient in 2016. Updating CoC estimates will help to assess the impact of new measures implemented since 2016 as part of the goal to eliminate HCV.

Abstract Background Previous research has shown millennials represent the fastest growing generation for those infected with the hepatitis C virus (HCV). Millennials are also a key driver in the opioid crisis, particularly in states of the Appalachian region including Kentucky. Despite research demonstrating a change in prevalence from baby boomers (born 1945–1965) to millennials (born 1980–1995), large representative studies providing evidence of the magnitude of this demographic shift are lacking in the United States. Our objective was to assess trends of HCV infection since 2016 in a large healthcare system located in an area of high prevalence of opioid use and HCV infection. Methods All individuals were screened for HCV infection in 2016, 2017, and 2018 within Norton Healthcare per standard risk-based criteria (e.g., injection drug users, baby boomers, etc.) as recommended by CDC, except for pregnant women who were universally screened since 2016. We tested for demographic shifts over time using longitudinal and time series analyses techniques Results A total of 86,243 individuals were screened for HCV infection from 2016 to 2018. Of those, 2,615 (3.0%) individuals screened positive for chronic HCV. The average age of those infected significantly decreased by an average of 3.7 years annually (from 47.3 years in 2016 to 39.9 years in 2018, P < 0.001). We forecast a plateau near the age of 28 years will be observed in just over 7 years. In addition, the proportion of millennials increased over time (33.6% in 2016, 42.4% in 2017 and 51.4% in 2018, P < 0.001), while baby boomers significantly decreased over time (44.0% in 2016, 38.8% in 2017, and 29.3% in 2018, P < 0.001). Lastly, over time, those with chronic HCV were more likely to be male (increasing from 49.6% to 54.4%, P = 0.008) and Hispanic (increasing from 1.6% to 17.7%, P < 0.001) Conclusion Our results suggest that HCV infection has become a predominately millennial disease, skipping a generation. These results correlate with trends seen with the opioid epidemic, which is driven by millennials. We conclude that the opioid crisis has led to a drastic demographic shift, and currently the typical HCV-infected individual is a younger male. Without interventions, this trend will continue for over seven years, plateauing near the demarcation of millennials and generation Z Disclosures All authors: No reported disclosures.

The frequency of hepatitis C virus (HCV) infection remains high in patients with chronic kidney disease (CKD) and plays a detrimental role in mortality in this population. According to the latest survey, the adjusted hazard ratio for HCV-positive versus HCV-negative patients on long-term dialysis was 1.12 (95% CI, 1.05 to 1.20) and 1.10 (95% CI, 0.98 to 1.22) for all-cause and cardiovascular mortality, respectively. An impairment on quality of life has also been documented in HCV-infected patients undergoing regular dialysis. Most clinicians have been so far reluctant to treat hepatitis C in patients with advanced CKD, due to concerns regarding low efficacy and safety of interferon-based regimens. The advent of all-oral, direct-acting antivirals (DAAs) has revolutionized treatment paradigms for HCV, including patients with other comorbidities such as CKD. Two combinations of DAAs have been recently approved for the treatment of HCV in advanced CKD: elbasvir/grazoprevir (evaluated in 1 randomized controlled trial) and ombitasvir/paritaprevir/ritonavir/dasabuvir with or without ribavirin (examined in some observational, single-arm studies). These antiviral combinations have provided high safety and efficacy (SVR12 rates >90%) in HCV-infected patients with stage 4–5 CKD. Sofosbuvir, a nucleotide analogue inhibitor of the HCV NS5B polymerase, is the cornerstone of most anti-HCV current regimens but is not currently recommended for patients with severe renal insufficiency (eGFR <30 mL/min per 1.73 m2). However, several small-sized studies have been published on the safety and efficacy of sofosbuvir-based regimens for patients with hepatitis C on maintenance dialysis>; overall, the viral response was satisfactory (SVR12 rates ranging between 58% and 100%) with a few drug-related drop-outs. Studies are in progress to assess whether ribavirin-free antiviral combinations with novel DAAs are a viable option for patients with severe renal impairment and chronic HCV infection.

Peginterferon Α

Direct-acting antivirals with or without peginterferon α (PEG-IFN α) plus ribavirin are now available for the treatment of hepatitis C virus (HCV) infection. Direct-acting antivirals are potent inhibitors of HCV replication, but some of them occasionally possess serious adverse events. We experienced a 64-year-old female with chronic HCV genotype 1b infection who showed elevated alanine aminotransferase of 528 IU/l at week 9 after the commencement of treatment of simeprevir with PEG-IFN α-2a plus ribavirin. However, she achieved sustained virological response at week 24 after the end of treatment. In Japan, we also have to treat elderly patients infected with HCV and/or advanced hepatic fibrosis. Until an effective interferon-free regimen is established, direct-acting antivirals with PEG-IFN plus ribavirin may still play a role in the treatment for certain patients. To avoid serious results from adverse events, careful attention and follow-up will be needed in the treatment course of simeprevir with PEG-IFN plus ribavirin for chronic HCV infection.

Background: Hepatitis C virus (HCV) infection is associated with significant morbidity and mortality. The effectiveness of sofosbuvir, as a new direct-acting antiviral (DAA) for chronic HCV infection, needs to be assessed and evaluated among patients with or without cirrhosis with all HCV genotypes. Aims: This study was conducted to determine the effectiveness of chronic HCV treatment as part of a combination therapy for all HCV genotypes in patients with or without cirrhosis. Study Design: A retrospective observational study. Methodology: All patients who received sofosbuvir treatment from the Pharmacy Department of Hamad General Hospital during a 12-month period (between 2014 and 2015) were included. Patients were observed up to 12 weeks after treatment course completion. Data were analyzed descriptively and compared using a paired t-test (alpha=0.05). Results: A total of 95 patients received sofosbuvir. All of these patients received sofosbuvir in combination with other antiviral medications. All HCV genotypes were included; 1a and 4 were the most dominant genotypes (37% and 30.5%, respectively). Half of the patients were treatment naïve. All patients achieved undetectable virus ribonucleic acid (RNA) starting from week 4 of the treatment. A sustained virological response at 12 weeks (SVR12) after completion of the treatment period was maintained in 95% of patients. Relapse was mostly observed in patients with genotype 1a (40%); no patients with HCV genotype 3 exhibited relapse. Conclusion: The SVR12 after sofosbuvir treatment was maintained in most patients, regardless of genotype, HCV complications HCV or co-administered drugs.
