Alcoholic subjects with abnormal liver chemistry studies are often assumed to have alcoholic liver disease, even though the diagnosis is not established by liver biopsy. To determine the magnitude of nonalcoholic liver disease in patients with heavy alcohol consumption, the data on 145 consecutive patients judged to consume at least 80 g of alcohol daily for prolonged periods, and who underwent liver biopsy at the University of Chicago, were reviewed. Nonalcoholic liver disease was suspected clinically and confirmed by liver biopsy in 40 (28 per cent), whereas alcoholic liver disease was suspected in 105 but confirmed in only 83 (80 per cent). The remaining 22 patients had liver disorders, including cholangitis or pericholangitis, acute hepatitis or some form of chronic hepatitis, for which they required appropriate therapy. Neither clinical features, hepatitis B surface antigen (HBsAg), anti-HBsAg nor serum glutamic oxaloacetic transaminase to serum glutamic pyruvic transaminase (SGOT:SGPT) ratios distinguished these 22 patients from those with alcoholic liver disease. Thus, liver biopsy is necessary for the identification of nonalcoholic liver disease in patients suspected of harboring alcoholic liver disease, since other clinical features do not allow identification of these patients.
