title: Cryofibrinogenemia associated with Sjögren's syndrome: a case of successful treatment with high-dose corticosteroid.
abstract: Cryofibrinogenemia (CF) has not been often reported as a complication of various rheumatic diseases. We describe a 44-year-old woman with CF associated with Sjögren's syndrome (SS), who developed digital necrotic ulcerations and purpura of the lower legs. Cryoprecipitate was detected in her plasma, and immunoelectrophoresis showed that the cryoprecipitate was cryofibrinogen. Alprostadil was intravenously administered, but the ulceration was aggravated. Subsequently, administration of high-dose prednisolone (PSL) at 60 mg/day was started, and the ulceration remarkably improved. Cryofibrinogen, detected before the administration of high-dose PSL, was negative after PSL. This is the first case presentation of CF associated with SS successfully treated with high-dose corticosteroid.
