[The presence and significance of HBe antigens and anti-HBe antibodies in HBs antigen positive patients].

There have been examined 105 sera of HBeantigen carriers, 30 of patients with chronic persistent hepatitis, 17 of patients with active hepatitis and 30 of HBeantigen-positive patients on chronic hemodialysis) for the presence of HBeantigen and antiHBe antibodies. A high percentage of HBeantigens was found in patients with chronic active hepatitis (88,2%) as well as in patients on chronic hemodialysis (86,7%) while the finding of antiHBeantigen in these two groups was low, 11,8% and 3,3%, respectively. The presence of HBeantigen in other two groups was lower, 26,7% in patients with chronic persistent hepatitis and 28,5% in patients with asymptomatic HBe antigenemia. AntiHBe antibodies were present in a higher percentage in patients with chronic persistent hepatitis (70%) than in asymptomatic HBeantigen carriers (57,1%). The presence of HBeantigens is not always sign of severe liver function disorder as well as the presence of anti HBe antibodies is not always sign of preserved liver function.

[The significance of serum gamma-glutamyl transpeptidase determination in the differentiation of icterus of various etiologies].

In a group of 29 patients with mechanical icterus and a control group of 38 patients (acute, chronic hepatitis and hyperbilirubinemia) there have been followed up alkaline phosphatase, leucinaminopeptidase and gammaglutamil transpeptidase activities aiming to evaluate the value of gamma GT in differentiation of icterus of various etiology. Comparing the values of the examined cholestase enzymes in patients of obstructive icterus it could be seen that gamma GT was positive in the largest percentage of the diseased, (69,6%), then APH (89,7%) AND LAP (86,3%). Gamma GT has shown to be selective test for obstruction of hepatobiliary tract but it is not selective for discovering cause of obstruction. It can be explained by the fact that activity of gamma GT could be found both in mechanical icterus caused by calculosis or tumours (with a very high activity) and in patients with hepatitis with cholestatic component, although in the decresed activity.
