Hepatitis C Therapy – Related Haematological Side Effects are Associated with Treatment Outcome / Hematološka Neželjena Dejstva Terapije Hepatitisa C Su Povezana Sa Ishodom Lecenja

Treatment of patients suffering from chronic hepatitis C with standard pegylated interferon alpha 2a plus ribavirin has limited efficacy. Therapy outcome is dependent on several factors of both the host and virus, including age, sex, stage of fibrosis, viral genotype, viral load, and occurrence of haematological adverse events during chronic hepatitis C treatment. The aim of this study was to determine the relationship between the viral and host factors and the haematological side effects of therapy with sustained virological response.

Fifty-four patients were treated with combined pegylated interferon alpha 2a plus ribavirin therapy. Hepatitis C virus genotyping, viral load, histopathological liver changes and biochemical parameters were evaluated for each patient before beginning treatment. Each patient’s blood count was analysed during each clinical visit.

Sustained virological response was achieved in 75,9% of patients. Baseline AST and ALT levels were significantly higher in patients with a poor response to therapy (p<0,05). Other clinical and laboratory parameters did not reach statistical significance. Both responders and non-responders developed anaemia. A decrease in thrombocytes, neutrophils and white blood cells was significantly associated with a sustained response to therapy (p<0,05, p<0,05 and p<0,001, respectively).

Sustained virological response was associated with lower baseline AST and ALT values and thrombocytopenia, leucopenia and neutropenia at the end of the treatment. All treated patients developed anaemia.
