About 50% of patients with chronic hepatitis C do not respond to interferon therapy and this failure is expensive. The aim of this study was to identify possible predictive factors of biochemical non-response during interferon therapy among biochemical, virological (HCV genotype), histological (Knodell's score) and pharmacokinetic (monoethylglycinexylidide formation test) pre-treatment parameters.Our study included 60 patients with chronic hepatitis C undergoing a course of Interferon therapy. Patients whose serum ALT levels were normal at the 3rd month of therapy and remained so until the end of treatment were regarded as responders.In univariate analysis, only the gamma-glutamyltransferase (gamma-GT) and the gamma-GT/alanine aminotranferase ratio were significantly higher in non-responder patients. Multivariate logistic analysis showed that high gamma-GT levels, high histological activity index, low monoethylglycinexylidide formation rate and viral genotype 1 were the best combination for the identification of non-responder patients (16.7% error rate). By adding alanine aminotranferase modification at the 1st month of therapy the probability error was reduced to 5%.These results show that the combination of biochemical, histological, virological and pharmacokinetic pre-treatment variables, associated with alanine aminotranferase modification at the 1st month of therapy, can predict non-response to interferon and allow therapeutic modifications. |
