[The systemic and local immune responses in patients with alcoholic liver cirrhosis depending on hepatitis C viral infection (HCV)].

The systemic and local immune response was studied in patients with alcoholic liver cirrhosis and the significance of the combined infection with HCV. To investigation were submitted 23 patients (16 males and 7 females) aged between 29 and 61 years with alcoholic liver cirrhosis. Of them 14 were anti-HCV(+) and 9 anti-HCV(-). As controls were used 36 clinically healthy individuals, matched by sex and age to the patients. The flow cytometric analysis of the lymphocyte (Ly) populations from the peripheral venous blood and of cells from liver aspirate obtained by blind liver biopsy according to Menghini, was performed with FacsTAR (Becton Dickinson). In the anti-HCV(-) patients, as compared to the controls (patients/controls) the Ly subpopulations were increased: CD3+/mm3:2010 +/- 738/1440 +/- 388; CD4+/mm3:1350 +/- 441/991 +/- 442; IL-2R+/mm3:133 +/- 78.5/31 +/- 20. In the anti-HVC(+) patients we established increased IL-2R+/mm3: 170 +/- 126 as compared with the controls and anti-HCV(-) patients. The suppressor/cytotoxic (CD8+) Ly with their suppressor (CD8+CD11b+) and cytotoxic (CD8+CD11b-) subpopulations and natural killers (CD16+) had a tendency to diminution in the anti-HCV(+) patients. In both examined groups the B (CD19+) Ly were non-significantly increased. The flow cytometric analysis of the cells from the liver specimen in 9 patients of whom 3 anti-HCV(-) and 6 anti-HCV(+) revealed that CD3+ on the average were 32.8% +/- 20.4% (from 9.2% to 65.1%); CD4+ were 21.1% +/- 7.4% (from 12.0% to 34.5%); CD8+ 22.6% +/- 11.8% (from 4.7% to 39.8%) and their values were higher in the anti-HCV(+) patients; the correlation CD4+/CD8+ = 1/1.09 +/- 0.6; CD16+ were 12.9% +/- 10.1% (from 1.9% to 34.8%); CD19+ varied from 3.2% to 27.8%; monocytes (CD14+) were 7.69% +/- 5.65 (from 2.0% to 15.8%) from the cells of the aspirate and their percentage contents was higher in the anti-HCV(+) patients. The results of out study revealed that in patients with alcoholic liver cirrhosis changes in the cell immune response were also observed and that they were more marked in infection with HCV.
