Brucella glomerulonephritis: Review of the literature and report on the first patient with brucellosis and mesangiocapillary glomerulonephritis

Abstract

Although mild proteinuria is commonly observed during the course of brucellosis, biopsy-proven glomerulonephritis (GN) is quite rare. We present the first case of mesangiocapillary glomerulonephritis (MCGN) associated with brucellosis and summarize all cases of Brucella GN published to date. Our patient, who had a congenital bicuspid aortic valve, also had heart failure, fever, urinary abnormalities and proteinuria. Renal biopsy revealed MCGN. Although the clinical features raised the possibility of GN associated with endocarditis, transesophageal echocardiography did not show any vegetations.
