Abstract
Hepatocellular carcinoma (HCC) is the most common complication of HCV infection leading to liver transplantation. We evaluated the impact of aetiology of liver disease on patient and graft survival following liver transplantation for HCC. From the Scientific Registry of Transplant Recipients (2002-2011), all adults who underwent liver transplantation for HCC were retrospectively included. Aetiology of liver disease was grouped into HCV, HBV, HCV-HBV co-infection and nonviral liver disease. Of 8,733 liver transplant recipients with HCC, 5507 had HCV, 631 had HBV, 163 were co-infected, and 2432 had nonviral causes of liver disease. In follow-up (48 ± 32 months), 8.2% had graft failure and 29.5% died. The mean rates of graft failure were 9.5%, 4.7%, 6.1% and 6.4% in HCV, HBV, HCV-HBV co-infection and nonviral liver disease, respectively (P < 0.0001). Post-transplant mortality rate in patients with HBV was 20.2%, HCV 31.0%, HCV-HBV 28.5% and nonviral 28.5% (P < 0.0001). This difference was significant starting one year post-transplant and became even more prominent later in follow-up. Five-year post-transplant survival was 64.7% in HCV, 77.7% in HBV, 71.0% in HCV-HBV and 69.1% in nonviral HCC (P < 0.0001). A diagnosis of HCV in patients with HCC was also independently associated with an increased risk of both graft failure (adjusted hazard ratio = 1.84 (1.46-2.33), P < 0.0001) and mortality (1.35 (1.21-1.50), P < 0.0001) in multivariate analysis. Patients with HCV-related HCC are at higher risk of adverse post-transplant outcomes. These patients should be considered for preemptive interferon-free antiviral therapy prior to or immediately following liver transplantation.

Abstract
Asian Americans represent an important cohort at high risk for viral hepatitis. To determine the prevalence of Hepatitis B virus (HBV) and Hepatitis C virus (HCV) infection and HBV vaccination in a Vietnamese community, a total of 322 Vietnamese subjects from a local doctor's office and annual Vietnamese Health Fair were included in this study. Demographic and clinical data were collected. 2.2% of the screened cohort tested positive for anti-HCV and 9.3% tested positive for HBsAg. Unlike HBV-positive subjects, HCV-positive subjects had significantly higher liver enzymes (P = 0.0045 and P = 0.0332, respectively). The HBV-positive group was more likely to report jaundice (P = 0.0138) and a family history of HBV (P = 0.0115) compared to HBV-negative subjects. Forty-eight patients (15.5%) reported a family history of liver disease (HBV, HCV, HCC, cirrhosis, other). Of this 48, 68.8% reported no personal history of HBV vaccination and 77.1% reported no family history of vaccination for HBV. Among the 183 subjects without a family history of liver disease, 156 (85.2%) reported no personal history of vaccination and 168 (91.8%) reported no family history of vaccination. HBV vaccination rates in those reporting a family history of liver disease were significantly higher (P =0.020). There was a high prevalence of HBV infection in this community screening. Nevertheless, the rate for HBV vaccination was low. The low prevalence of abnormal liver enzymes in HBV-positive subjects emphasizes the need for screening to be triggered by risk factors and not by abnormal liver enzymes.

A phase II dose finding study of darbepoetin alpha and filgrastim for the management of anaemia and neutropenia in chronic hepatitis C treatment. J Viral Hepat 2008; 15:370-8.

Abstract
Dose reductions of pegylated interferon alpha and ribavirin may be avoided by using growth factors. This phase II clinical trial assesses the dose, efficacy and safety of darbepoetin alpha and filgrastim for treatment of anaemia and neutropenia associated with combination therapy for hepatitis C virus (HCV). Chronic hepatitis C patients (n = 101) received pegylated interferon alpha-2b (1.5 mug/kg once weekly) and ribavirin (800-1400 mg once daily). Patients with anaemia [haemoglobin (Hb) </= 10.5 g/dL] received darbepoetin alpha (3 mug/kg once every 2 weeks); the dose was titrated to achieve a Hb level of 12.0 g/dL. Patients with neutropenia [absolute neutrophil count (ANC) </= 0.75 x 10(9)/L] received filgrastim with the dose titrated from 150 mug QW to 300 mug thrice weekly to maintain ANC >/= 0.75 x 10(9)/L and <10 x 10(9)/L. During antiviral therapy, 52% of patients required darbepoetin alpha, filgrastim or both. Hb at the time of darbepoetin alpha initiation was 10.2 +/- 0.4 g/dL. After 81 days of darbepoetin alpha, Hb increased by 1.9 +/- 1.0 g/dL to 12.1 +/- 1.1 g/dL (P < 0.0001). Filgrastim resulted in a significant increase in ANC [0.75 +/- 0.16 x 109/L to 8.28 +/- 5.67 x 10(9)/L (P < 0.0001)]. In treatment-naïve patients, 48% achieved sustained virological response (SVR), whereas 27% of patients previously treated with a course of pegylated interferon alpha achieved SVR. Low viral load, nongenotype 1 and treatment with growth factors were independently associated with SVR. Mild and severe anaemia were associated with quality of life impairments. Darbepoetin alpha resulted in an improvement in the Vitality domain of Short Form-36. No significant adverse events were related to growth factors. During anti-HCV therapy, filgrastim improved neutropenia and darbepoetin alpha improved both anaemia and quality of life. Future randomized clinical trials are needed to establish the impact of growth factors in improving sustained virological response.
