ABSTRACT Hepatitis C virus (HCV) infection is a complex public health problem, characterized by a high prevalence of chronic infection, an increasing burden of HCV-associated disease, low rates of testing and treatment, and the prospect of increasing incidence associated with the epidemic of injection drug use. Three-quarters of chronic HCV infections occur among persons born from 1945 through 1965. Prevention efforts are complicated by limited knowledge among health care professionals, persons at risk and in the public at large. At the Centers for Disease Control and Prevention, efforts to improve primary and secondary prevention effectiveness center on policy development, education and training initiatives, and applied research. This report provides a brief overview of some of these efforts, including the development of testing recommendations for the 1945-1965 birth cohort, research and evaluation studies in settings where persons who inject drugs receive services, and a national viral hepatitis education campaign that targets health care professionals, the public, and persons at risk.

    ABSTRACT: In the United States, the peak hepatitis C virus (HCV) antibody prevalence of 4% occurred in persons born in the calendar years 1940-1965. The goal of this study was to examine observed and projected age-specific trends in the demand for liver transplantation (LT) among patients with HCV-associated liver disease stratified by concurrent hepatocellular carcinoma (HCC). All new adult LT candidates registered with the Organ Procurement and Transplantation Network for LT between 1995 and 2010 were identified. Patients who had primary, secondary, or text field diagnoses of HCV with or without HCC were identified. There were 126,862 new primary registrants for LT, and 52,540 (41%) had HCV. The number of new registrants with HCV dramatically differed by the age at calendar year, and this suggested a birth cohort effect. When the candidates were stratified by birth year in 5-year intervals, the birth cohorts with the highest frequency of HCV were as follows (in decreasing order): 1951-1955, 1956-1960, 1946-1950, and 1941-1945. These 4 birth cohorts, spanning from 1941 to 1960, accounted for 81% of all new registrants with HCV. A 4-fold increase in new registrants with HCV and HCC occurred between the calendar years 2000 and 2010 in the 1941-1960 birth cohorts. By 2015, we anticipate that an increasing proportion of new registrants with HCV will have HCC and be ≥60 years old (born in or before 1955). In conclusion, the greatest demand for LT due to HCV-associated liver disease is occurring among individuals born between 1941 and 1960. This demand appears to be driven by the development of HCC in patients with HCV. During the coming decade, the projected increase in the demand for LT from an aging HCV-infected population will challenge the transplant community to reconsider current treatment paradigms.

    ABSTRACT: Background & AimsDespite advances in HCV treatment, recent data on treatment uptake is sparse. HCV treatment uptake and associated factors were evaluated in a community-based cohort in Vancouver, Canada. Methods The CHASE study is a cohort of inner city residents recruited from January 2003–June 2004. HCV status and treatment were retrospectively and prospectively determined through data linkages with provincial virology and pharmacy databases. Logistic regression analyses were used to identify factors associated with HCV treatment uptake. ResultsAmong 2913, HCV antibody testing was performed in 2405, 64% were HCV antibody-positive (n = 1533). Individuals with spontaneous clearance (18%, n = 276) were excluded. Among the remaining 1257 HCV antibody-positive participants (mean age 42, 71% male), 29% were Aboriginal. At enrolment, the majority reported recent injecting (60%) and non-injecting drug use (87%). Between January 1998 and March 2010, 6% (77 of 1257) initiated HCV treatment. In adjusted analyses, Aboriginal ethnicity [adjusted odds ratio (AOR) 0.23; 95% CI 0.10, 0.51] and crack cocaine use (AOR 0.61; 95% CI 0.37, 0.99) were associated with a decreased odds of receiving HCV treatment, while methamphetamine injecting (AOR 0.16; 95% CI 0.02, 1.18) trended towards a lower odds of receiving treatment. HCV treatment uptake ranged from 0.2 (95% CI 0.0, 0.7) per 100 person-years (PYs) in 2003 to 1.6 (95% CI 0.9, 2.6) per 100 PYs in 2009. ConclusionHCV treatment uptake remains low in this large community-based cohort of inner city residents with a high HCV prevalence and access to universal healthcare.
