A Case of Whipple's Disease Related Infectious Endocarditis

Abstract

Whipple's disease is caused by Tropheryma whipplei and is known to have protean clinical presentation which could be influenced by patient's immunologic and genetic features. In contemporary literature abundant amount of data could be found on extensive prevalence of infectious endocarditis caused by Tropheryma whipplei. This article presents history of a patient who was observed because of ischemic heart disease, angina pectoris, myocardial infarction, possible ischemic cardiomyopathy and in whom infectious endocarditis complicated by severe aortic regurgitation needing aortic valve replacement surgery was eventually diagnosed. Our patient did not meet Duke criteria, which is a sign of infectious endocarditis caused by Tropheryma whipplei, but a thorough analysis of the disease course, clinical features, heart ultrasound and clinical improvement on specific therapy against Tropheryma whipplei aroused our suspicion, and morphological and bacteriological analysis of the involved (excised) valve, confirmed the diagnosis of Whipple disease. The article presents differential diagnostic criteria of aortic insufficiency and possible causes of coronary insufficiency in the absence of marked coronary atherosclerosis.
