Study design: Case Report
Abstract: We describe the case of a 60-year-old man who presented with rash and renal failure and was subsequently diagnosed with Bartonella quintana mitral valve endocarditis. Key findings included skin biopsy showing leukocytoclastic vasculitis, renal biopsy showing crescentic glomerulonephritis, and high-titer IgM and IgG antibodies against B quintana. This case underscores the varied presentations of culture-negative endocarditis and its association with glomerulonephritis in infectious diseases such as Bartonella.
