Histological course of alcoholic hepatitis. Influence of abstinence, sex and extent of hepatic damage.

The factors influencing the histological evolution of alcoholic hepatitis without cirrhosis have been evaluated in 26 patients (14 males and 12 females) submitted to repeated liver biopsies over a mean period of 1.7 years (1-3). Drinking habits during follow-up were checked by inquiries to patients and relatives and by serial determination of ethanol in urine. At the end of the follow-up, 9 patients (34.6%) had progressed to cirrhosis, 5 (19.2%) still had alcoholic hepatitis and 12 (46.1%) had normal liver or only minimal changes. Nine patients continued drinking heavily, 4 reduced their daily intake markedly and 13 stopped drinking. Improvement of liver lesions was observed in 9 of the abstainers and in 3 non-abstainers that had markedly reduced their alcohol consumption. Among the 9 patients with persistent heavy alcohol consumption, 5 developed cirrhosis and 4 still showed alcoholic hepatitis in their last biopsy. Cirrhosis also developed over 1-2 years in 4 females who had stopped drinking, indicating a marked influence of sex on the course of alcoholic hepatitis. Progression of the disease to cirrhosis despite abstinence occurred in a high proportion of women (4/7) but not in men (0/6). These observations indicate that discontinuation of heavy alcohol consumption often results in improvement of liver lesion in patients with alcoholic hepatitis. However, the risk of progression to cirrhosis remains elevated in women.
