[Henoch-Schonlein nephritis: diagnosis and prognosis problems in childhood].

Abstract Henoch-Schonlein purpura (HSP) is the most common vasculitis in childhood and is characterized by sistemic leukocytoclastic angiitis, mainly affecting small vessels of the skin, joints, gastro-intestinal tract and kidneys. Renal involvement is the most important cause of morbidity and mortality in patients with HSP. The aim of this study was to evaluate renal involvement in children with HPS and the prognoses of short- and long-term outcome of patients diagnosed with HS nephritis. We conducted a retrospective study based on observation files of hospitalized children with Henoch-Schonlein purpura admitted in the Nephrology Department" Sf. Maria" Hospital, during 20 years. The results showed that the prognosis of Henoch-Schonlein nephritis is relatively good and long-time morbidity is predominantly associated with initial presentation and renal involvement.
