Abstract:
Objectives To explore the clinical features and pathological types of childhood Henoch-Sch?nlein purpura ne-phritis (HSPN)with proteinuria. Methods Clinical and pathological data of 180 children with HSPN presenting with proteinuria were retrospectively analyzed in groups according to 24-hour urinary protein levels. Results The moderate proteinuria (57 cases, 31.7%) was the most common clinical type, followed by high-grade proteinuria (51 cases, 28.3%), mild proteinuria (46 cases, 25.6%) and microalbuminuria (26 cases, 14.4%). According to the International Study of Kidney Disease of Children , the major pathological type of HSPN are grade II (92 cases, 51.1%) and grade III (73 cases, 40.6%). The main pathological changes of moderate proteinuria were grade II (31 cases, 54.4%), and the main pathological changes of high-grade proteinuria were grade III (33 case, 64.7%). The pathological grade was progressively increased along with severity of proteinuria. The difference was statistically significant (χ2=39.54, P=0.002). The main immunopathological type was IgA+IgM (84 cases, 46.7%), followed by IgA+IgM+IgG (55 cases, 30.6%). No correlation was found among immunopathological typing, pathological typing and clinical typing (P>0.05). Conclusions The HSPN children with massive proteinuria show more severe pathological changes, but the se-verity of clinical symptoms is not completely consistent with the pathological damages.
