Management of hepatitis C virus in special populations: patient and treatment considerations

Abstract

The most common chronic blood-borne infection in the United States is caused by hepatitis C virus. An estimated 3.9 million people (1.8%) in the United States have been infected with the hepatitis C virus, excluding certain subpopulations who are at high risk for hepatitis C virus infection. Among these subpopulations are an estimated 255,000 (15%) of prison inmates and 175,000 (22%) of homeless people. Prevalence of hepatitis C virus infection is also high among veterans (6.6% overall and even higher among homeless veterans). The single most important risk factor for hepatitis C virus infection is injection drug use; up to 90% of illicit injection drug users are infected with hepatitis C virus. This review describes the prevalence of hepatitis C virus in special populations and discusses the treatment options for patients with severe disease, transplant recipients, and patients at high risk for infection. Close monitoring and management of therapeutic side effects are required to assist these patients in adhering to therapy.
