title: [Case of Henoch-Schönlein purpura nephritis successfully treated with tonsillectomy and steroid pulse therapy].
abstract: A 30-year-old Japanese man was admitted to our hospital because of fever, sore throat, abdominal pain, purpura skin lesion of the lower legs, and macrohematuria. On admission, his urine was positive (++) for protein; the sediment contained 100 red blood cells per high-power field, and the daily proteinuria level was 1.7 g. Renal biopsy was performed, and we diagnosed Henoch-Schönlein purpura nephritis (HSPN). Six months after the renal biopsy, the patient underwent a tonsillectomy. The pathological diagnosis of the resected tonsils was chronic tonsillitis. After tonsillectomy, the daily proteinuria had decreased to 0.1 g and the sediment contained only 10-19 red blood cells per high-power field. High-dose methylprednisolone therapy (500 mg/day for 3 days for three courses) was started two weeks after the tonsillectomy, followed by oral prednisolone at the initial dose of 30 mg on alternate days. The oral prednisolone was tapered gradually over 1 year. Antiplatelet drug (dipyridamole, 300 mg/day) and angiotensin II receptor antagonist (olmesartan, 10 mg/day) were also administered. This combination therapy resulted in a significant decrease in proteinuria and disappearance of microhematuria. The patient finally achieved clinical remission. Recent reports have shown that in patients with IgA nephropathy, combined tonsillectomy and methylprednisolone pulse therapy have an effect on clinical remission. In addition, it has been suggested that HSPN and IgA nephropathy represent a spectrum of clinical presentations of similar disorders. The result of this case indicated that this combination therapy had a favorable effect on clinical remission in adult patients with HSPN.
