Cryofibrinogenemia in Henoch-Schönlein purpura: report of a case

A patient with Henoch-Schönlein purpura (HSP) had exacerbations of disease that correlated closely with the presence of cryofibrinogenemia. Cryofibrinogen was absent consistently during asymptomatic intervals. To our knowledge, such a pattern has not been described previously in typical HSP. We suggest that all patients with HSP be screened for cryofibrinogenemia during the active phase of disease to determine the incidence of this abnormality.
