Infection with hepatitis C virus (HCV) was recently diagnosedin a 45-year-old man when a positive enzyme-linked immunosorbentassay was followed by a polymerase chain reaction assaythat showed a viral load of 835,000 copies/mL. The patient probablyacquired the infection when he was using intravenous heroin, a practice he quit 10 yearsago. The patient is immune to both hepatitis A and hepatitis B viruses, and there is no coinfectionwith HIV. Liver biopsy shows moderate cellular inflammation (grade 3) and bridging fibrosis(stage 3) but no evidence of cirrhosis. Iron staining shows no abnormal iron deposition in theliver. The HCV genotype is 1A.
