Abstract

Among 211 patients undergoing gastroduodenoscopy five had been carriers of Australia antigen. The same instrument had been used on all, and follow-up examination was carried out two and four months after the gastroscopy. Twelve patients died during the follow-up period of their original disease. Two additional patients became Australia-antigen positive. One of these had liver cirrhosis. In the other, surgery with multiple infusions of albumin had been carried out after gastroscopy and could have been the cause of the Australia-antigen transmission. No proven case of hepatitis transmission occurred in this group of patients.

Abstract

The measurement of total pepsin activity by colorimetry, and gastrin by radioimmunoassay method was performed on the sera of 100 patients (80 with duodenal ulcer and 20 with non-ulcer dyspepsia) before and 4 weeks after the end of antibacterial treatment for eradication of Helicobacter pylori. While in the sera of non-HP-eradicated cases (n = 26) no change of total pepsin activity and gastrin assessing occurred, in the sera of HP-eradicated cases (n = 74), a mean decrease of 31% and 23% was observed for total pepsin activity and gastrin respectively (p
