[67-year-old patient with speech disorder and dysphagia].

A 67-year-old man who had been heart transplanted ten years before was admitted to our hospital because of diarrhea. During his stay he developed a severe lingual and facial angioedema. After excluding hereditary angioedema caused by a deficiency in functional C1 esterase inhibitor we focused on adverse effects of his drugs. The medication was composed of Aspirin, Enalapril, Diltiazem, Everolimus, Mycophenolate Mofetil, Bisoprolol, Pravastatin, Esomeprazol and Allopurinol. The angioedema disappeared with anti-allergic treatment. The administration of the suspected trigger enalapril was stopped. However weeks later the patient was admitted again with angioedema. Due to missing urticaria Aspirin was unlikely the causer. The only new drug the patient had been medicated with was Everolimus for 30 days. We assumed a link between the angioedema and Everolimus. Consequently we changed the immunosuppressive regime. After stopping Everolimus no angioedema occurred.

CONCLUSIONS

Everolimus is a potential trigger of angioedema.
