[Glomerulonephritis in the Schoenlein-Henoch syndrome in childhood]

Ten children suffering from anaphylactoid purpura Schoenlein-Henoch and presenting urinary abnormalities of various degrees and reported. The histological and immunohistochemical tests allowed to distinguish two types of glomerulonephritis in these patients: focal glomerulonephritis and extracapillary glomerulonephritis. The prognosis was always favorable: no relationship was found between the clinical signs and symptoms and the findings in the kidney. The authors discuss, on a practical and theoretical level, the indications for kidney biopsies in children with the Schoenlein-Henoch syndrome.
