[Prevalence of HBSAG in blood donors and patients at the central hospital of Maputo, Mozambique, 1985].

A study is made of 681 donors who came to the Blood Bank of Maputo Central Hospital in Mozambique during the months of November, 1984, to January, 1985. By means of the technique of counterimmunoelectrophoresis it was determined that 18.6% of donors were positive for Ag HBs. Likewise, 90 patients were analyzed; these patients were hospitalized in the Gastroenterology Service of the hospital with different clinical diagnoses: primary liver carcinoma (14), acute hepatitis (24), cirrhosis (10), chronic hepatitis (7), and others (35). 41.6% of the patients hospitalized with hepatitis were type B. There was a significant relationship between Ag HBs carriers and patients with primary liver carcinoma.
