aim. The incidence of hepatitis C infection is high
in alcoholics. The aim of our study was to evaluate the immune
nonspecific cell and the humoral mediated disorders in alcoholic
liver disease (ALD) associated or not with chronic hepatitis
Material and methods.
We selected 20 heavy drinkers (intake - over 80g ethanol/day
for more than 10 years) with (8 patients) and without (12 patients)
chronic viral C hepatitis. Besides the diagnostic tests including
liver biopsy, hemoleucogram (leukocyte formula), serum iron
level, protein electrophoresis were performed in all patients,
as well as cryoglobulins, rheumatoid factor (RF), immunoglobulins,
antinuclear autoantibodies and circulating immune complexes.
The circulating B cells with positive CD19 markers (LyB CD19+)
were evaluated by flow cytometry.
All patients had reversible neutropenia and thrombocytopenia.
The values of LyB CD19+ were low in all patients. All patients
had similar IgG levels. The RF, cryoglobulins and autoantibodies
were absent in the group of patients with ALD and HCV infection.
The values of LyB are low in ALD with or without HCV infection.
The markers of autoimmunity (RF) or of B cell proliferation
(cryoglobulins) were absent in patients with ALD abd HCV infection.
Although HCV is a lymphotrophic virus, the presence of HCV had
no permissive effect on the proliferation of LyB in ALD, probably
due to the depressive effect of chronic alcohol intake on LyB.
