Kidney-limited recurrence in a patient with microscopic polyarteritis.
A 58-year-old woman with kidney-limited recurrence of microscopic polyarteritis (MPA) is described. The patient had a history of histologically-confirmed MPA 7 years previously, which had been in remission with corticosteroid treatment for 30 months followed by no medication thereafter. However, in February 1994, clinical manifestations including leg edema and proteinuria developed, followed by rapidly progressive renal insufficiency. Renal biopsy revealed crescentic glomerulonephritis with necrotizing vasculitis. Furthermore, at the same time antimyeloperoxidase antibody (MPO-ANCA) was detected in plasma. She was diagnosed as having kidney-limited recurrence of MPA without systemic presentation. Corticosteroid therapy was reinstituted, and the renal function improved, with a decrease in the titer of MPO-ANCA.
