Rickettsiose vom Fleckfiebertyp: Gemeinsames Auftreten mit einem linksventrikulären Thrombus und einer koronaren Ein-Gefäß-Krankheit

Abstract

A 44-year-old German fell ill in Libya, where he had been living for 10 years, with high fever, rigor and a nonitching centrifugally spreading macular rash, which had spared the head, hands and soles. In addition, a systolic cardiac murmur was heard. The Weil-Felix reaction had a titre rising within 3 days from 1:160 to 1:640, confirming the diagnosis of rickettsial disease, the total clinical picture indicating typhus. On treatment with chloramphenicol (1 g three times daily i.v.) the fever subsided within 5 days. On the ninth day treatment was changed to oral doxycyclin, 200 mg daily for 3 weeks. Echocardiography surprisingly revealed a floating thrombus, about 4 x 8 cm, attached to the hypo- and even akinetic apex of the left ventricle. In addition there was single-vessel coronary disease. Since the segmental contraction abnormality persisted after the typhus had been cured, a causal connection with the rickettsial disease is unlikely. The thrombus was removed at the time of a aortocoronary bypass operation: his course has been unremarkable since then.
