title: [Hepatitis B antigens systems in schistosomiasis mansoni].
abstract: The authors have studied the antigenic systems HBs and HBe and B virus hepatitis in 155 patients with mansonic schistosomiasis and have found: a) 22,5% HBsAg positivity in patients with the hepatosplenic form of the disease which was associated with histologic liver alterations and 8,7% anti-HBs positivity in patients with the hepatointestinal form of the disease which was associated with a preserved liver histology; in controls they have found 1% positivity for HBsAg. b) HBeAg and anti-HBe were of good prognostic value.
