Editor's Notes
HCC, hepatocellular carcinoma; HCV, hepatitis C virus. This slide depicts the natural history of hepatitis C infection, as gleaned from cohorts of posttransfusional patients. These posttransfusional cohorts have been most informative because they are able to pinpoint the exact time of infection and are, therefore, able to estimate fairly precisely the duration of disease. After acute infection, the predilection for chronicity is remarkable: Approximately 85% of patients progress to chronic infection, whereas only an elite 15% to perhaps 25% experience spontaneous resolution. Among those with chronic HCV infection, a stable course is seen in approximately 80% of patients, whereas 20% will develop cirrhosis. Once cirrhosis has supervened, a variable course is still observed; most patients will progress slowly, but about one quarter will experience liver failure, and approximately 1% will develop HCC annually. In other words, among 100 patients with acute infection, approximately 4 will develop a highly undesirable clinical outcome. However, it is possible that investigators may find that this is only a minimum estimate of the number of patients who will experience these outcomes as the cohort now matures.
