[Crescentic glomerulonephritis and primary Gougerot-Sjögren syndrome].

Glomerulonephritis complicating primary Gougerot-Sjögren's syndrome is extremely rare. We report the case of a 72-year old woman with primary Gougerot-Sjögren syndrome complicated by progressive renal failure. Kidney biopsy revealed a crescentic glomerulonephritis. A rapid improvement occurred with corticosteroids. This observation is, at our knowledge, the first case of crescentic glomerulonephritis described during this disease. A review of the literature concerning glomerulonephritis complicating primary Gougerot-Sjögren syndrome is reported.
