Summary

Endocarditis byAspergillus species in patients without prior cardiovascular surgery is extremely rare and difficult to diagnose. We report and discuss a 69-year-old patient with hairy cell leukemia who developed severe bilateral pneumonia and metastatic subcutaneous nodules from whichA. fumigatus was cultured. He died after 18 days of treatment with an adequate dose (0.7 mg/kg/day) of amphotericin B intravenously. Fungal endocarditis and a myocardial infarction due to a septic thrombotic occlusion of the left coronary artery byA. fumigatus appeared to be the cause of death.A. fumigatus could still be cultured from the aortic valve postmortem despite a total dose of 756 mg amphotericin B. In case of metastatic spread ofAspergillus spp., endocarditis should be suspected.

Zusammenfassung

Bei abwehrgeschwächten Patienten kann eine Endokarditis durchAspergillus sp. auch ohne gefäßchirurgischen Eingriff auftreten, die allerdings extrem selten und schwer zu diagnostizieren ist. Wir berichten über einen 69 Jahre alten Patienten mit Haarzelleukämie, bei dem sich eine beidseitige Pneumonie entwickelte. Aus metastatischen subkutanen Knötchen wurdeA. fumigatus angezüchtet. Trotz Behandlung mit Amphotericin B in adäquater Dosierung (0,7 mg/kg/Tag i.v.) verstarb der Patient 18 Tage nach Therapiebeginn. Als Todesursache fanden sich eine Pilzendokarditis und ein Herzinfarkt infolge septisch- thrombotischen Verschlusses der linken Koronararterie, ausgelöst durchA. fumigatus. Trotz Behandlung mit Amphotericin B i.v. in einer Gesamtdosis von 756 mg konnteA. fumigatus noch aus autoptisch entnommenen Material aus der Aortenklappe kultiviert werden. Bei metastatischer Ausbreitung vonAspergillus spp. sollte eine Endokarditis vermutet werden.
