Hepatitis C virus (HCV) is the most important cause of transfusion-related non-A, non-B hepatitis. It is also thought to be the prime cause of non-transfusion-related or sporadic chronic liver disease. To assess the extent of HCV infection and its significance in this last form, we evaluated the clinical, serological and histological features of 84 consecutive HCV-related patients without a history of blood or blood products transfusion, alcohol or intravenous drug abuse or other known risk factors. Our results indicate that 68 patients (81 %) had signs of chronicity, and 33 (39.2%) had superimposed cirrhosis. Serum abnormal alanine aminotransferase and γ-glutamyltransferase activities represented good predictive markers of liver histological signs of chronicity. The levels of serum gammaglobulins were found to parallel histological severity of liver disease. One or more hepatitis B virus (HBV)-associated markers were present in 52 patients (61.9%). Only 6 (7.1 %) were chronic HBV carriers, and 3 of them had signs of active virus replication. These data indicate that HCV plays a major role in the etiology of sporadic chronic liver disease. Its presence is associated with histological forms of chronic liver disease in most patients, who likely represent chronic HCV carriers.

Abstract

Hepatitis C virus (HCV) is the most important cause of transfusion-related non-A, non-B hepatitis. It is also thought to be the prime cause of non-transfusion-related or sporadic chronic liver disease. To assess the extent of HCV infection and its significance in this last form, we evaluated the clinical, serological and histological features of 84 consecutive HCV-related patients without a history of blood or blood products transfusion, alcohol or intravenous drug abuse or other known risk factors. Our results indicate that 68 patients (81 %) had signs of chronicity, and 33 (39.2%) had superimposed cirrhosis. Serum abnormal alanine aminotransferase and γ-glutamyltransferase activities represented good predictive markers of liver histological signs of chronicity. The levels of serum gammaglobulins were found to parallel histological severity of liver disease. One or more hepatitis B virus (HBV)-associated markers were present in 52 patients (61.9%). Only 6 (7.1 %) were chronic HBV carriers, and 3 of them had signs of active virus replication. These data indicate that HCV plays a major role in the etiology of sporadic chronic liver disease. Its presence is associated with histological forms of chronic liver disease in most patients, who likely represent chronic HCV carriers.
