Background/Aims Risks and benefits of simeprevir plus sofosbuvir in patients with advanced cirrhosis are unknown. We assessed the safety and sustained virologic responses (SVR) of simeprevir plus sofosbuvir with and without ribavirin in patients with Child-Pugh (CP)-B/C vs. CP-A cirrhosis and compared to matched untreated controls. Methods Multicenter cohort of adults with HCV genotype 1 and cirrhosis treated with simeprevir plus sofosbuvir with/without ribavirin for 12 weeks. Controls were matched on treatment center, age, CP class and model for end-stage liver disease (MELD) score. Results Of 160 patients treated with simeprevir plus sofosbuvir with/without ribavirin, 35% had CP-B/C and 64% had CP-A, with median baseline MELD 9 (IQR 8–11). SVR12 was achieved by 73% of CP-B/C vs. 91% of CP-A (p<0.01). CP-B/C vs. CP-A had more early treatment discontinuations (11% vs. 1%), adverse events requiring hospitalization (22% vs. 2%), infections requiring antibiotics (20% vs. 1%) and hepatic decompensating events (20% vs. 3%) (all p<0.01). There were 2 deaths: 1 CP-B/C (liver-related) and 1 CP-A (not liver-related). In multivariate analysis, CP-B/C independently predicted lack of SVR12 (OR 0.27, 95% CI 0.08–0.92). In comparing simeprevir plus sofosbuvir treated patients vs. matched untreated controls, adverse events requiring hospitalization (9% vs. 13%, p=0.55), infections (8% vs. 6%, p=0.47) and events of decompensation (9% vs. 10%, p=0.78) occurred at similar frequency. Conclusions Simeprevir plus sofosbuvir with/without ribavirin has lower efficacy and higher rates of adverse events in patients with CP-B/C cirrhosis compared to CP-A. The frequency of adverse safety outcomes were similar to matched untreated controls, suggesting safety events reflect the natural history of cirrhosis and are not related to treatment.

Racial/ethnic and socioeconomic disparities exist in DAA initiation. Substance use may also influence patient or provider decision making about DAA initiation. Strategies are needed to ensure equitable access to DAAs, even in insured populations.

Background Few population-based studies have described characteristics and management of patients with chronic hepatitis B (CHB) in the USA. Methods We retrospectively studied adults with CHB in the Northern California Kaiser Permanente Medical Care Program (KPNC) from July 2009 to December 2010 (n = 12,016). Laboratory tests, treatment patterns, and hepatocellular carcinoma (HCC) surveillance were ascertained during a “recent” 18-month study window (July 2009–December 2010), or as “ever” based on records dating to 1995. Results The mean age was 49 years; 51 % were men, 83 % Asian, and 87 % KPNC members >5 years. Overall, 51 % had ≥1 liver-related visit, 14 % with gastroenterology or infectious disease specialists, and 37 % with primary care providers (PCP) only. Less than 40 % of patients had both hepatitis B virus (HBV) DNA and ALT testing conducted recently, while 56 % of eligible patients had received HCC surveillance. Recent laboratory testing and HCC surveillance were more frequent in patients seen by a specialist versus PCP only (90 vs. 47 % and 92 vs. 73 %, respectively, p values <0.001). During the study period, 1,649 (14 %) received HBV treatment, while 5 % of untreated patients had evidence of treatment eligibility. Among 599 patients newly initiated on HBV therapy, 76 % had guideline-based indications for treatment. Conclusions Most patients initiated on HBV treatment met eligibility, and very few patients with evidence of needing treatment were left untreated. However, monitoring of ALT and HBV DNA levels, as well as HCC surveillance, were not frequent, underestimating the proportion of patients that warranted HBV therapy. Viral monitoring and cancer surveillance are therefore important targets for improving the scope of CHB care in the community setting.
