title: Acute glomerulonephritis associated with acute Q fever: case report and review of the renal complications of Coxiella burnetii infection.
abstract: We report a case of acute glomerulonephritis associated with acute Q fever. An abattoir worker with a nonspecific febrile illness and pneumonia and abnormal liver function test results developed hematuria, proteinuria, and acute renal failure that resolved with appropriate antimicrobial therapy. Renal biopsy demonstrated diffuse proliferative and exudative glomerulonephritis. Serological tests confirmed recent infection with Coxiella burnetii, with a fourfold rise in the titer of phase II antibody, positive phase II IgM antibody, and negative phase I antibody. Other known causes of glomerulonephritis were excluded. Most reports of renal complications of C. burnetii infection describe glomerulonephritis associated with endocarditis due to chronic Q fever. Renal involvement in patients with acute C. burnetii infection has been rarely described. Glomerulonephritis should be recognized as a complication of acute C. burnetii infection and endocarditis due to chronic Q fever.
