A 59-year-old woman with chronic active hepatitis C was treated with recombinant human interferon alpha-2a. After three days of administration, the patient complained of diplopia with dizziness and head heaviness. Ophthalmic examinations revealed a disturbance of the movement of left eye ball to the outer side without any other neurological signs. The diplopia, which was diagnosed as abducent nerve paralysis, improved rapidly and reversed at about 6 weeks after discontinuation of interferon and during infusion of hydrocortisone. To our knowledge, this is the first report of abducent nerve paralysis associated with alpha-2a interferon.

A 57-year-old woman was scheduled to receive recombinant interferon-alpha retreatment for chronic active hepatitis C. During the course of therapy, the patient showed rapid onset of oliguria, dizziness, edema, and a pre-shock state. She was subsequently admitted to hospital and was diagnosed as having nephrotic syndrome. After admission, albumin-dominant proteinuria persisted despite the discontinuation of interferon therapy. Light microscopy of a renal needle biopsy specimen showed interstitial lymphoid cell infiltration, but no marked changes of the glomeruli and no staining for immunoglobulin or complement. Electron microscopy showed diffuse effacement of the glomerular epithelial foot processes, leading to a diagnosis of minimal change nephrotic syndrome with interstitial nephritis. Proteinuria resolved after the initiation of oral prednisolone therapy (1 mg/kg per day). The number of patients with chronic hepatitis C requiring interferon retreatment is increasing rapidly. We herein report this rare case of acute onset of nephrotic syndrome during interferon-alpha retreatment.
