title: [Activity of guanase in serum and liver function tests in HBe antigen-positive chronic hepatitis].
abstract: Forty-one patients with chronic hepatitis were divided into an HBe antigen-positive group (n = 13) and an HBe antigen-negative group (n = 28) to clarify the relationship between the presence of HBe antigen and liver function. In the HBe antigen-positive group, the activities of serum alanine aminotransferase (p less than 0.01), aspartate aminotransferase (p less than 0.05) and guanase (p less than 0.01) were significantly higher than those in the HBe antigen-negative group. The correlation coefficient between the HBe antigen titer and guanase activity was 0.528, which was higher than the corresponding values for alanine aminotransferase and aspartate aminotransferase. The determination of guanase activity in serum may be useful for evaluating the clinical severity of HBe antigen-positive chronic hepatitis.
