[A sustained response in chronic hepatitis C treated with interferon]. / La risposta sostenuta nella epatite cronica C trattata con interferone.

We analyzed 27 subjects with long-term response, from a group of 110 interferon treated patients with biopsy-proven chronic hepatitis and serum anti-HCV antibodies. The following variables were assessed as potential predictors: sex, age, ALT level before the therapy was started, liver structure, type of interferon, total amount of interferon. Total amount of administered interferon statistically correlated with long-term response by univariate analysis. Nevertheless upon stepwise logistic multivariate analysis none of them was independently predictive of long-term response. Additional studies would be needed in order to develop a model capable of predicting from pre-treatment features which patients are likely to have long-term response.
