Hepatitis C virus (HCV) serotype in the asymptomatic HCV-infected patients from selected groups.

In asymptomatic hepatitis C virus (HCV)-infected blood donors and persons from high risk groups (intravenous drug users and hemodialyzed patients) HCV serotypes 1, 2, 3, 4 and 6 have been detected. The most frequent was serotype 1. In the group of intravenous drug users (IDU) a coexistence of different serotypes was observed.

[Serological markers of selected viral infections transmitted by parenteral route in drug addicts].

Investigations included a group 80 asymptomatic drug addicts. They were examined immunoenzyme method aiming at detection infection by HIV, HBV, HCV and HDV. Cases of seropositive HIV results were confirmed by means WB.

[The gamma globulin-fibrinogen index in the differential diagnosis of decompensated cirrhosis and primary liver cancer].

The gammaglobulin-fibrinogen index (GgF) was determined in 30 healthy subjects and 160 patients with chronic hepatic diseases related to HB infection. The group included 60 cases of chronic active hepatitis, 60 with compensated cirrhosis, 28 with decompensated cirrhosis, and 12 with primary hepatic carcinoma. The GgF index was found to be useful for preliminary diagnosis of the hepatic neoplasm and for differentiation of similar clinical pictures of decompensated cirrhosis and primary hepatic carcinoma.
