Whipple’s disease or intestinal lipodystrophy is an infection induced by Tropheryma whipplei. It is rare
with an estimated incidence of 0.4 per million. Symptoms are arthropathy, weight loss, and diarrhoea,
but other organs notably the central nervous system may be affected. We demonstrate a case of cardiac

Cardiac complications in Whipple’s disease
Differential diagnosis of these intracardiac abnormalitieswould include congestive heart failure, ischaemic cardio-myopathy, hypertrophy due to hypertension or aortic steno-sis, viral myocarditis, nutritive or toxic cardiomyopathy, orFabry disease. However, the reaction on antibiotic therapysupports our view of a cardiac complication of Whipple’sdisease in this case.
When the disease is suspected, duodenal-biopsy speci-
mens should be obtained. Histological analysis reveals gran-ular foamy macrophages stained purple with PAS. Duodenalsamples are inﬁltrated by macrophages.
Untreated Whipple’s disease can be fatal. However, anti-
biotic therapy leads to rapid improvement in clinical status.
