Haemophagocytic syndrome secondary to endocarditis due to Bartonella henselae

Culture-negative endocarditis due to Houston Complex Bartonella henselae acquired in Noumea, New Caledonia.

A 44-year-old man with a bioprosthetic aortic valve suffered destructive endocarditis with severe embolic disease due to Bartonella henselae infection. Multilocus sequence typing was successfully performed with crude preparations of operative tissue as templates, and the infecting organism was determined to be typical of the Houston clonal group, although it was never cultured from blood or tis...

Culture-negative endocarditis due to Bartonella quintana.

Bartonella spp. was first described as a possible cause of culture-negative endocarditis in 1993, and has since emerged as a significant cause of this condition worldwide. We describe a complicated case of culture-negative endocarditis in an immune-competent male patient, which was confirmed on resected heart valves to have been caused by Bartonella quintana by broad-range 16S ribosomal RNA pol...

Bartonella Henselae endocarditis mimicking ANCA associated vasculitis

Bartonella can cause a damaging endocarditis and patients typically need valve replacement. Infective endocarditis (IE) and small vessel vasculitis (SVV) can have similar clinical features and the presence of ANCA can be misleading and it is critical to differentiate between IE and SVV since their treatment are vastly different.

Bivalvular Bartonella henselae prosthetic valve endocarditis.

Prosthetic valve endocarditis is an uncommon manifestation of infection with Bartonella species. Herein, we report a case of Bartonella henselae endocarditis involving prosthetic mitral and aortic valves. The patient had a favorable outcome with combined medical and surgical therapy. Concomitant crescentic glomerulonephritis led to an initial mistaken diagnosis of Wegener's granulomatosis.
