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.

Renal deterioration often occurs in cases of infectious endocarditis (IE), but, IE- associated nephritis with rapidly progressive glomerulonephritis (RPGN) is rare. Patients with severe infection (e.g., IE) sometimes show positivity for cytoplasmic antineutrophil cytoplasmic antibodies (C-ANCA). Therefore, diagnosis and treatment are very difficult in cases of RPGN with IE and positivity for C-ANCA. Such cases are rare, only 12 have been reported in the English literature. Herein, we describe the case of a 50-year-old man who presented with RPGN with IE and tested positively for C-ANCA. He was referred to our hospital because of leg edema, purpura and renal dysfunction. Laboratory tests revealed serum creatinine elevation and positivity for C-ANCA and proteinase 3-specific (PR3)-ANCA. RPGN and acute renal failure were diagnosed. Hemodialysis and steroid therapy were started. Streptococcus oralis was isolated by blood culture. Transthoracic echocardiography revealed grade III mitral valve insufficiency with two vegetations. Therefore, IE was diagnosed. The steroid therapy was stopped, and antibiotic therapy was begun. Because there was no improvement, surgical therapy was performed. The operation was successful, but the patient died of brain hemorrhage. Our experience in this case indicates C/PR3-ANCA positive RPGN must be ruled out in patients with infectious disease, particularly IE, together with renal symptoms, and renal biopsy should be performed.
