Peginterferon alpha/ribavirin combination therapy for the treatment of hepatitis C infection.

Chronic infection with the hepatitis C virus is widespread in the United States. This disease is associated with a progression of fibrosis of the liver leading to liver cirrhosis in as many as 20% of cases. The current standard of care for the treatment of chronic hepatitis C infection is combination therapy with pegylated interferon alpha plus ribavirin. In more than 50% of patients, this regimen has been shown to induce a sustained viral response, defined as undetectable hepatitis C viral ribonucleic acid (RNA) for 6 months after the end of treatment. Typically, patients are treated for 24 or 48 weeks. A number of possible adverse events are associated with combination therapy, and patient empowerment through supportive nursing care is critical to facilitating patient adherence to treatment.
