Résumé
A 64-year-old woman was admitted with vertebral osteomyelitis and polyarthritis (both knees and the right shoulder). She had had no health problems before these conditions developed. Joint culture grew methicillin-resistant Staphylococcus aureus. During hospitalization, hematuria, proteinuria, azotemia, and decreased C3 were reported. The renal biopsy showed mesangial proliferative glomerulonephritis with C3 and IgA co-dominant deposits on immunofluorescence staining. Following incision and drainage of the right shoulder and right knee, and intravenous vancomycin for 15 weeks, the C-reactive protein, proteinuria, hematuria, and C3 level all normalized. Here, we report a case of Staphylococcus-associated glomerulonephritis with a brief review of the literature.
