    Abstract: For patients with hepatitis C virus (HCV)-related decompensated cirrhosis, poor prognosis was documented due to the development of portal hypertension-related complications and hepatocellular carcinoma. Sofosbuvir-based direct-acting antiviral agents (DAAs) has revolutionized the treatment landscape of HCV, particularly in this subpopulation. To date, real-world efficacy, tolerability, and safety profiles for Taiwanese HCV-related decompensated cirrhosis treated by DAAs have not been reported. Methods: Between December 2015 and June 2020, 50 consecutive HCV-related Child-Turcotte-Pugh (CTP) classes B or C cirrhotics treated by sofosbuvir-based DAAs (with daclatasvir: 7, with ledipasvir: 32, with velpatasvir: 10, with ledipasvir then shifted to velpatasvir: 1) were enrolled. Forty-seven (94%) patients used DAAs in combination with low-dose ribavirin. SVR 12 was defined by undetectable HCV RNA ( 〈 15 IU/mL) at treatment end and 12 weeks after the completion of therapy. Results: The mean age of the enrolled patients was 68.1 ± 11.2 years, 18% of the patients were CTP class C, and the baseline HCV RNA level was 5.42 ± 1.2 log 10 IU/mL. The genotype distribution was as follows: 1a: 3; 1b: 34; 2: 9; 6: 3; and one patient with an unclassified HCV genotype. After DAAs treatment, the rates of undetectable HCV RNA at week 4 and at the end of the treatment were 88.9% and 98.0%, respectively. Subjective adverse events were reported by 42.0% of the patients, but they were generally mild and could be relieved by medications. One patient did not finish therapy due to sepsis with multiple organ dysfunction. The overall SVR 12 rate was 96.0% (CTP class B: 97.6%, CTP class C: 88.9%). A significant improvement in hepatic functional reserve was noted after successful antiviral therapy. Conclusion: For patients with HCV-related decompensated cirrhosis, which has been considered a contraindication for interferon-based therapy, sofosbuvir-based all-oral DAAs provided high treatment efficacy, acceptable safety, and good tolerability.

    Abstract: Immunosuppressant-related acceleration of fibrosis has been documented in chronic hepatitis C (CHC) patients who receive organ transplantation (Tx), and sustained virological response (SVR) rates for these patients by pegylated interferon (IFN)-based therapy are generally poor and associated with unfavorable safety profiles. In addition, IFN treatment varies by patient and poses a high risk of post-renal Tx graft rejection. This study was aimed to investigate the efficacy and safety of all oral direct acting antivirals (DAAs) for CHC patients following organ Tx. Methods: A total of 32 organ Tx (liver: 17, kidney: 13, kidney then liver: 1, and heart: 1) patients with CHC on an oral DAA (paritaprevir/ritonavir, ombitasvir, and dasabuvir: 11, daclatasvir and asunaprevir: 4, sofosbuvir-based: 17) were enrolled in the study. DAAs regimen was based by genotype/subtype, patient characteristics, drug interaction profiles, and health insurance coverage. Results: Mean patient age was 61.4 ± 9.5 years, 50.0% male, and 15.6% with cirrhosis. Fourteen (43.7%) patients experienced unsuccessful IFN treatment. Genotype distribution was as follows: 1a: 6, 1b: 17, 2: 7, 3: 1, and 6: 1. Mean time between Tx and DAAs therapy was 77.3 ± 11.0 months. Baseline HCV RNA before DAAs was 6.20 ± 0.19 log 10 IU/mL. After DAAs, the distribution of week 2 HCV RNA was as follows: 〈 15 IU/mL (53.1%), 15 to 50 IU/mL (15.6%), 50 to 100 IU/mL (6.3%), and 〉 100 IU/mL (25.0%), respectively. The rates of undetectable HCV RNA ( 〈 15 IU/mL) at week 4 and end-of-treatment were 93.8% and 100%, respectively. Subjective adverse events during therapy were generally mild, with no treatment terminations. After posttreatment follow-up, all 32 patients (100%) achieved SVR 12 . Conclusion: Highly responsive treatment and favorable tolerability were achieved by all oral DAAs in this difficult-to-treat patient population.

    Abstract: Hepatitis C virus (HCV) and human immunodeficiency virus (HIV) coinfection is common because the two pathogens share their transmission route. Studies have suggested that coinfection is associated with accelerated hepatic fibrosis, increased hepatic decompensation, and hepatocellular carcinoma development. Historically, the sustained virological response (SVR) rates for patients undergoing pegylated interferon (PEG-IFN)-based therapy are poor owing to advanced liver disease, immune dysfunction, and poor medical adherence. This study aimed to investigate the efficacy and safety of oral direct-acting antivirals (DAAs) in HCV-HIV–coinfected patients. Methods: Between January 2017 and February 2020, 52 consecutive HCV-HIV–coinfected patients treated with oral DAAs (paritaprevir/ritonavir, ombitasvir, and dasabuvir: 7; daclatasvir and asunaprevir: 1; glecaprevir and pibrentasvir: 15; and sofosbuvir-based drugs: 29) were enrolled. The DAA regimen was selected based on the genotype/subtypes, patient characteristics, potential drug-drug interaction profiles, and health insurance reimbursement criteria. SVR 12 was defined as undetectable HCV RNA ( 〈 15 IU/mL) at the end of therapy and 12 weeks after therapy completion. Results: The mean age of the enrolled patients was 42 ± 10.2 years; 92.3% of the patients were male and 32.7% had advanced fibrosis or cirrhosis. Nine (17.3%) patients had failed previous IFN therapy. The genotype distribution was as follows: 1a: 8; 1b: 23; 2: 14; 3: 1; and 6: 6. The baseline HCV RNA level before DAA administration was 6.56 ± 0.9 log 10 IU/mL, and 67.3% of patients had baseline HCV RNA 〉 2 000 000 IU/mL. After posttreatment follow-up, all 52 patients (100%) achieved SVR 12 . Subjective and laboratory adverse events during therapy were generally mild, and none of the patients terminated therapy early. Conclusion: A highly effective treatment response and good tolerability were achieved using the oral DAAs for the HCV-HIV–coinfected patient population, which has been considered difficult to treat using IFN-based therapy in the past with urgent unmet medical needs.

    Abstract: Based on the previously published results, 12 weeks of sofosbuvir (SOF) 400 mg/day plus ribavirin (RBV), the current direct antiviral agent regimen reimbursed by Bureau-of National-Health-Insurance (BNHI) of Taiwan for genotype-2 chronic hepatitis C (CHC), is suboptimal in efficacy, especially for difficult-to-treat subpopulations such as liver cirrhosis, previous interferon (IFN) treatment failure, and high viral-load. This study aimed to evaluate the efficacy and safety of SOF plus daclatasvir (DCV) for Taiwanese genotype-2 CHC patients. Methods: Between March 2017 and December 2018, a total of 50 consecutive genotype-2 CHC patients who completed 12 weeks combination of SOF (400 mg/day) plus DCV (60 mg/day) with or without RBV by investigators were enrolled for analyses. When RBV was added, weight-based (800-1200 mg/day) approach was applied. Sustained virological response (SVR 12 ) was defined by undetectable HCV RNA ( 〈 15 IU/mL) at the end and 12 weeks after completion of therapy. Results: The mean age was 62.0 ± 11.4 years, 16 (32.0%) of them were males and 20 (40.0%) of them failed to previous IFN. Severity of liver diseases was as follows: ≤F2 fibrosis: 24.0%; F3 fibrosis: 40.0%, Child-Pugh A cirrhosis: 30.0%; and Child-Pugh B-C cirrhosis: 6.0%. The mean baseline HCV RNA level was 6.19 ± 0.91 log 10 IU/mL and 30 (60.0%) had baseline HCV RNA ≥ 2 million IU/mL. The rates of undetectable HCV RNA ( 〈 15 IU/mL) at weeks 2, 4, and end-of-treatment were 40%, 94%, and 100%, respectively. Majority (66.7%) of patients with detectable HCV RNA at week 2 belonged to low-level viremia ( 〈 50 IU/mL). Subjective adverse events (AEs) and laboratory abnormalities were more common for patients combining RBV. Grades of AEs were generally mild and all patients finished therapy without interruption. After post-treatment follow-up, all 50 patients (100%) achieved SVR 12 . Conclusion: Our real-world cohort of Taiwan showed that a 12-week SOF/DCV-based treatment was well-tolerated and highly effective for genotype-2 CHC patients with or without liver cirrhosis.

    Abstract: The treatment of chronic hepatitis C (CHC) infection underwent a significant transformation with the introduction of all-oral direct-acting anti-virals (DAAs). These medications offered a high success rate in treatment, shorter duration, good tolerability, and expanded treatment options. However, a residual risk of hepatocellular carcinoma (HCC) development remained for a few patients even after achieving sustained virological response (SVR). To date, there is a lack of real-world data on evaluating risk factors associated with de novo HCC in CHC patients post-SVR, particularly in Taiwan. Methods: Between January 2017 and December 2019, a total of 671 consecutive CHC patients who achieved SVR after receiving DAAs were included for analysis. Patients with a history of HCC or liver transplantation prior to DAAs, a short follow-up period ( 〈 1 year), or treatment failure with DAAs were excluded. The primary outcome was the development of HCC following the initiation of DAAs. Variables associated with the primary outcome were assessed using multivariate Cox proportional hazards models. Results: The mean age of the enrolled patients was 65.1 ± 12.8 years, with 39.6% of them being male. Among the patients, 30.6% had advanced (F3-4) fibrosis, and the median follow-up period was 2.90 years. The cumulative incidence of HCC in CHC patients post-SVR12 was 1.6% at 1 year, 4.4% at 2 years, 4.8% at 3 years, 5.3% at 4 years, and 6.1% at 4.8 years, respectively. Variables independently associated with de novo HCC were advanced liver fibrosis (hazard ratio [HR] = 6.745; 95% CI = 1.960-23.218; p = 0.002), end-of-treatment 12 weeks (EOT 12 ) alpha-fetoprotein (AFP) 〉 7 ng/mL (HR = 3.059; 95% CI = 1.215-7.669; p = 0.018), EOT 12 albumin-bilirubin (ALBI) grade ≥ 2 (HR = 2.664; 95% CI = 1.158-6.128; p = 0.021), and body mass index (BMI) ≥ 25 kg/m 2 (HR = 2.214; 95% CI = 1.011-4.852; p = 0.047). Conclusion: Despite achieving viral clearance with DAAs, CHC patients still face a residual risk of de novo HCC. Establishing a risk stratification model based on independent variables could facilitate the prediction of future HCC development and enhance screening strategies.
