  • Title: Necrotizing glomerulonephritis in rheumatoid arthritis.
    Author: Kuznetsky KA, Schwartz MM, Lohmann LA, Lewis EJ.
    Journal: Clin Nephrol; 1986 Nov; 26(5):257-64. PubMed ID: 3802589.
    Abstract:
    Rheumatoid arthritis may be associated with several glomerular lesions including amyloidosis, mesangial proliferation and membranous glomerulonephritis. Systemic vasculitis is a well-recognized extra-articular complication of rheumatoid arthritis, but necrotizing glomerulonephritis, the glomerular expression of vasculitis, has been described infrequently. This report comprises four patients with rheumatoid arthritis who underwent renal biopsy for declining renal function, proteinuria and active urine sediments. Pathology revealed that three patients had segmental necrotizing glomerulonephritis without significant glomerular immunoglobulin deposition. The fourth had segmental necrosis associated with diffuse membranous glomerulonephritis. We conclude that necrotizing glomerulonephritis is part of the spectrum of glomerular lesions seen in patients with rheumatoid arthritis. Because of therapeutic considerations involving the use of cyclophosphamide, necrotizing glomerulonephritis should be a diagnostic consideration in the rheumatoid arthritis patient with signs of glomerulonephritis and rapidly deteriorating renal function.
