Role of ethnicity in risk for hepatocellular carcinoma in patients with chronic hepatitis C and cirrhosis.

BACKGROUND AND AIMS: In the United States, hepatocellular carcinoma (HCC) is more common among Asians and African Americans than Caucasians, with chronic hepatitis C virus (HCV) infection accounting for up to half of the patients. Our study examined ethnicity as a potential risk factor for HCC among patients with chronic hepatitis C. METHODS: We conducted a case-control study of 464 patients with chronic hepatitis C and cirrhosis (207 cancer patients and 257 controls) using medical records and pathology records at 4 medical centers. We estimated odds ratios with 95% confidence intervals by using conditional logistic regression on case-control sets, matched within study centers and study period on sex and age groups (< or =45, 46-55, 56-65, >65 yr). To control for potential confounding caused by severity of cirrhosis and residual confounding caused by age, we also included Child-Turcotte-Pugh (CTP) scores and age (continuous variable) in all regression analyses. RESULTS: Compared with Caucasians, the cancer risk was increased significantly among Asians (adjusted odds ratio, 4.3; 95% confidence interval, 2.1-9.0 for men, and 4.6; 1.2-18.5 for women) and somewhat increased among African-American men (adjusted odds ratio, 2.4; 95% confidence interval, 0.9-6.3). CONCLUSIONS: This study suggests that, among patients with chronic hepatitis C and cirrhosis, liver cancer risk is increased 4-fold in Asians and may be doubled in African-American men, compared with Caucasians. These results need confirmation in larger studies from racially diverse populations, but, if confirmed, these results point to high-risk populations that should be targeted for screening and preventive efforts.

Impact of a designated hepatology nurse on the clinical course and quality of life of patients treated with rebetron therapy for chronic hepatitis C.

A two- to three-fold increase in mortality from hepatitis C is predicted in the next 10-20 years as the largest cohort of patients age. More qualified providers are needed to care for this population. The objective of this study was to assess the impact of a hepatology nurse practitioner as compared to care by a physician on the quality of life and treatment outcomes of patients with chronic hepatitis C. Seventy-five patients with chronic hepatitis C were assigned to either a nurse practitioner or physician and asked to complete a SF-36 Health Survey quarterly to measure their perceived quality of life.Two-sided t-tests comparing the quality of life scores in the physician and nurse practitioner groups at weeks 1, 12, and 24 were calculated using SPSS version 12.0 (Chicago, IL). Although marginal differences between physicians and nurse practitioners were noted for physical function at week 1, bodily pain at week 12, and role physical at week 24 by the patients, no statistically significant differences were observed overall in the quality of life scores reported by the patients according to healthcare provider. The treatment outcome data for the nurse practitioner groups showed 12/25 (48%) of patients with genotype 1 achieved a sustained virologic response as did 13/22 (59%) of patients with genotype 2 or 3. In the physician groups, 11/27 (41%) of patients with genotype 1 achieved a sustained virologic response as did 14/23 (61%) of patients with genotype 2 or 3. These results suggest nurse practitioners can provide effective care to the chronic hepatitis C population.
