[Prosthetic Valve Endocarditis using Immunosuppressive Agent for Atopic Dermatitis;Report of a Case]

Abstract

A 26-year-old man had a history of severe atopic dermatitis. He was taking immunosuppressive drug. Mitral valve replacement (MVR) had been performed for infective endocarditis March 2008. He came to our hospital in July 2012 complaining of fever of 39 degrees Celsius. According to computed tomography (CT) and transesophageal echocardiography (TEE), we diagnosed that he had cerebral embolism and bacterial infection of prosthetic valve. Antibiotic treatment was performed for 2 weeks after the onset of cerebral infarction. Then we conducted re-MVR. The postoperative course was satisfactory. He showed a gradual improvement in the level of consciousness and was discharged. In patients with atopic dermatitis, bacteria can penetrate into the blood from the skin easily. So they are often affected by bacteremia. There are some reports that infective endocarditis is likely to occur in immunosuppressed patients. It is suggested that immunosuppressive drug was involved in the development of prosthetic valve endocarditis (PVE) in addition to atopic dermatitis in this patient.
