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.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.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 log10 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%), and100 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 SVR12.Highly responsive treatment and favorable tolerability were achieved by all oral DAAs in this difficult-to-treat patient population.

Background: Liver transplantation is a challenging procedure that is associated with perioperative morbidity and mortality, so it is justifiable to perform such a procedure in high-volume procedure centers. Organ shortage remains a major issue in Taiwan. Due to the difficulty in establishing a high-volume procedure center, it is important to review the overall outcome of patients undergoing liver transplantation at a small-volume procedure center to determine if performing such a procedure is justified. Methods: Between April 2001 and May 2005, 26 adults underwent deceased donor liver transplantation at Taipei Veterans General Hospital. The overall outcomes were reviewed in terms of 90-day mortality, 1-year and 3-year survival rates. In addition, the patients were divided into a hepatocellular carcinoma (HCC) group (n = 12) and a benign end-stage liver disease (ESLD) group (n = 14). The clinical demographics, 90-day mortality, 1-year and 3-year survival rates were reviewed and compared between the 2 groups. Results: The 90-day mortality was 15.3% in the whole series, 8.3% in the HCC group and 18.7% in the ESLD group. The overall 1-year and 3-year survival rates were 76.9% and 63.5%, respectively, for the whole series. For the 2 groups, the respective 1-year and 3-year survival rates were 83.3% and 71.4% in the HCC group, and 71.4% and 57.1% in the ESLD group. The survival difference was not significant (p = 0.319) between the 2 groups. In the HCC group, the 1-year and 3-year disease-free survival rates were 88.9% and 71.1%, respectively. Conclusion: The survival rates between ESLD and HCC patients undergoing liver transplantation at a small-volume procedure center were comparable. The results of the whole series were not satisfactory, but the results for the HCC group were acceptable. [J Chin Med Assoc 2008;71(4):186–190]
