title: Prosthetic valve endocarditis caused by Bartonella quintana in a patient during immunosuppressive therapies for collagen vascular diseases.
abstract: Bartonella quintana, known to cause various clinical symptoms, is increasingly recognized as one important cause of culture-negative endocarditis. We report a case of infectious endocarditis with B. quintana on the prosthetic valve, accompanied by proteinase 3-antineutrophil cytoplasmic antibody-positive collagen vascular disease-like symptoms 1 year earlier.
