Abstract
We report two patients with chronic hepatitis C, both nonresponders to a previous course of interferon (IFN), who developed or suffered an exacerbation of sarcoidosis while under treatment with IFN-alpha2a, ribavirin and amantadine. Patient 1: symptoms appeared after week 4 and treatment was withdrawn at month 9 due to severe weight loss, marked dyspnea, muscular weakness, dryness of mouth and facial paralysis. Stage III pulmonary sarcoidosis and polyneuropathy were confirmed. The patient had become steroid dependent and nine months after cessation of the treatment dyspnea and muscular weakness still persisted. She achieved a complete sustained response of hepatitis C. Patient 2: presented with a previous diagnosis of granulomatous hepatitis with chronic active hepatitis C and chronic dermatitis. The treatment exacerbated a cutaneous sarcoidosis. Furthermore, hiliar adenopathies consistent with stage I sarcoidosis became evident. Sarcoidosis responded to corticosteroids, but elevated transaminases and hepatitis C viraemia resisted. Hence, the combination of amantadine with ribavirin and IFN can develop or exacerbate subclinical sarcoidosis. A synergistic effect of these three drugs is suggested.
