Uncommon side-effects of interferon

Abstract

Beside the clinical manifestations usually observed during the treatment of chronic viral hepatitis with interferon, a small number of side-effects, less frequent and sometimes unexpected, have been described. These neurological, pulmonary, metabolic, cardio-vascular or psychiatric manifestations are uncommon but potentially severe. We here describe three cases of stroke that occurred during treatment with interferon in which the role played by the molecule could be questioned.
