RESUMO
The importance of the different endoscopic procedures in the transmission of hepatitis B was investigated prospectively by following up for 6 months all HBV-negative patients endoscoped from April to October 1981. A group of patients admitted in the same period to our unit constituted the control group. Controls were obtained after 1, 3, and 6 months from endoscopy. Infection rate was 1% for the control group and 0.45% for the endoscopy group. The difference is not statistically significant. These results strongly support the view, already present on an uncontrolled basis in the literature, that transmission of hepatitis B is not associated with gastrointestinal endoscopy.

To investigate the susceptibility of chronic symptomless HBsAg carriers to the hepatotoxic effect of ethanol 296 such carriers were followed up for 3 1/2 years with repeated biochemical and clinical examinations. A control group of HBsAg-negative blood donors matched by age, sex, occupation, duration and type of ethanol intake, and state of nutrition were followed up for the same period. Chronic symptomless HBsAg carriers seemed to be at risk of hepatic abnormalities when drinking an amount of ethanol which was harmless for HBsAg-negative subjects (less than 80 g). It may therefore be advisable to suggest complete abstinence from ethanol for HBsAg carriers.
