Abstract

BACKGROUND:

Renal impairment, usually due to tubulointerstitial and rarely glomerular disorders occurs in 10 to 30% of patients with primary Sjögren's syndrome. Extracapillary proliferation may also be observed.

CASE REPORT:

A 62-year-old woman with primary Sjogren's syndrome diagnosed 12 years earlier, developed microscopic polyangeitis leading to rapidly progressive renal failure. Antipolynuclear anticyclosine antibody (ANCA) serology was positive (pANCA, anti MPO) and the renal biopsy evidenced necrotizing glomerulonephrities with extracapillary proliferation. Outcome was favorable despite a recurrence one year after onset.

DISCUSSION:

Extracapillary proliferative glomerulonephritis is characterized by hematuria and proteinuria associated with renal failure. Renal impairment may worsen rapidly, sometimes leading to an emergency situation because the renal prognosis is directly related to delay to treatment. This case illustrates an uncommon complication of Sjögren's syndrome, compared with the usual tubulointerstitial disorders. The mechanism remains unknown, but outcome can be favorable with rapidly initiated immunosuppressor treatment.
