title: [Anaphylactoid purpura in infancy and childhood (author's transl)].
abstract: The clinical picture and the laboratory data of 40 patients with anaphylactoid purpura as well as its etiology and pathogenesis are discussed. The clinical expression and the rate of complications does not differ from that described in the literature. 45% of the patients showed renal involvement, three patients had severe glomerulonephritis. Up to now there is a lack of typical laboratory tests to confirm the diagnosis of anaphylactoid purpura. This study suggests neutrophilia and initial creased fibrin/fibrinogen split products in serum and decreased C3 levels are poor prognostic criteria correlating with appearence and severity of a complicating glomerulonephritis.
