[Seizures during the treatment with interferon for chronic C hepatitis].

Interferon alpha (IFN-alpha) is a well-established first-line treatment for chronic viral hepatitis. Side effects of IFN-alpha therapy are common but generally mild and self-limited. Generalized seizures during IFN-alpha therapy are very uncommon and are present in clinical isolated cases and usually in association with high doses of IFN-alpha. In our case a female of 39 years old, seizures have occurred at low doses of IFN-alpha used as therapy for chronic C viral hepatitis. As it comes to our knowledge, till now, there were published only 4 cases of generalized seizures that occurred during treatment with IFN-alpha for chronic C viral hepatitis. The physiopathology of this complication is unknown. Generalized seizures can be reasonable due to IFN-alpha therapy, as long as the patient didn't have any seizure history, or other factors, which can develop seizures. Neurological examination, EEG and brain scan were normal. The recurrence of these seizures was absent stopping IFN-alpha therapy without any other seizure treatment.
