A series of 31 cases of children affected by nephropathy, out of a total of 120 presenting with Schönlein-Henoch syndrome, observed in a period of seven years is reviewed. 87% of the patients evidenced renal involvement in the first month of disease. The manifestations of nephropathy were: Isolated hematuria. Hematuria-proteinuria less than 40 mg/m2/h. Nephrotic syndrome. Hematuria-nephrotic syndrome. Hematuria-nephrotic syndrome renal insufficiency. Biopsy was performed in 13 cases (41.9%). With regard to the ISKDC rules, the histological classification was: type I, one patient; type II, three patients; type III, seven patients; type V, one patient; type VI, one patient. Evolution was favorable in 30 cases, independently of treatment applied, and a complete remission was obtained in all of them.
