[e/Anti-e system in liver disease].

HBeAg and anti-HBe were tested by RIA (Abbott Kits) in 53 patients (38 HBsAg +) with acute viral hepatitis (AVH), in 27 patients (5 HBsAg +) with chronic active hepatitis (CAH), in 54 (8 HBsAg +) with cirrhosis, in 32 (17 HBsAg +) undergoing haemodialysis, in 6 HBsAg carriers and in 45 controls. Most of the patients with HBsAg + AVH were HBeAg + in the first week and showed seroconversion to anti-HBe within the fourth week of the illness. Two from the four patients still HBeAg + in the fourth week seroconverted later on and clinically recovered, one is still HBsAg +/HBeAg + in the seventh week and one developed CAH HBsAg +/HBeAg +. High prevalence of HBeAg was found in the haemodialysed (94%) and in the patients with CAH (80%) while anti-HBe was more frequent in the HBsAg carriers (100%) and in the cirrhotics (62,5%). Among the patients HBsAg-, none was HBeAg + while 18% with CAH, 21,7% with cirrhosis, 26,6% of the haemodialysed and 4% of the controls were anti-HBe +. Our data, relating to AVH, are similar to those referred in the literature, but show conversely high prevalence of anti-HBe in CAH and in cirrhosis.
