[Cytogenetic disorders iin patients with chronic hepatitis B and C]

The chromosomal apparatus of peripheral blood lymphocytes was studied in 19 patients with chronic hepatitis B (CHB) and 17 patients with chronic hepatitis C (CHC). Significant changes in cytogenetic indices were revealed in the both groups. Incidence of aberrant cells in CHC exceeded significantly that in CHB (15.3 +/- 1.5% vs 11.1 +/- 0.9% respectively; P < 0.05). Frequencies of aberration per cell and chromatid fragments were also significantly higher in CHC compared with both CHB and practically normal donor groups.
