Disseminated echinococcosis with repeated anaphylactic shock. Treated with mebendazole

Abstract

A 46-year-old man, who was twice operated on for echinococcosis and who suffered from recurrent angioneurotic edema, was hospitalized with anaphylactic shock. Chest x-ray examination showed round lesions in the lungs; Casoni, immunofluorescence and hemagglutination tests for echinococcosis were strongly positive. With a diagnosis of disseminated echinococcosis, drug treatment with mebenzadole was given for 29 weeks (the last 22 weeks a dose of 1,200 mg daily). No side effects were observed, allergic manifestations disappeared, and the round lesions were noticeably reduced. The titer of hemagglutination fell gradually, and IgE concentration initially increased and later fell. Mebendazole is proposed as a drug of choice in the cure of disseminated hydatidosis; it may both alter the indication for operation and considerably improve the prognosis.
