[Nephropathy in Schoenlein-Henoch purpura. Long-term developmental aspects in 55 cases].

Fifty five patients with Schöelein-Henoch nephropathy were reviewed. These patients were divided into five groups according to the clinical picture initially presented: 1. Hematuria with proteinuria. 2. Hematuria with nephrotic syndrome. 3. Isolated hematuria. 4. Hematuria, nephrotic syndrome and renal failure. 5. Proteinuria. From a histopathological point of view, they were classified into six groups according to ISKDC criteria. A strong correlation was found between clinical presentation and histological lesion. The worst prognosis corresponded to patients with nephrotic syndrome and renal failure, whose biopsy revealed more than 75% of glomeruli with epithelial crescents.
