ABSTRACT
Objectives To explore the changes of serum interleukin-33 (IL-33), IgA anti-endothelial cell antibodies (AECA) and IgA anticardiolipin antibodies (ACA) in acute stage of Henoch-Sch?nlein purpura (HSP) in children and its clinical signiif-cance. Methods Thirty-seven children with acute HSP admitted to hospital were selected from Nov.2012 to Jan.2013. Twenty healthy children were selected as healthy controls. The serum levels of IL-33 were measured by double anti-body sandwich en-zyme-linked immunosorbent assay (ELISA) and the serum levels of AECA-IgA and ACA-IgA were detected by double antigen sandwich ELISA. Results Serum levels of IL-33, AECA-IgA and ACA-IgA in patients with acute HSP were signiifcantly higher than those in healthy controls (P<0.001). According to different clinical types, the serum levels of IL-33, AECA-IgA and ACA-IgA were signiifcantly higher in mixed-type HSP (with joint involvement and gastrointestinal symptoms and/or kidney damage) than those in HSP patients with only joint, abdomen or renal involvement (P<0.05). Serum levels of IL-33 in acute stage of HSP had a positive correlation with AECA-IgA (r=0.752, P<0.001) and ACA-IgA (r=0.788, P<0.001). Conclusions The immune pathological injury in vessels caused by the interaction of IL-33, AECA-IgA and ACA-IgA may be the important pathogenesis of HSP, which may provide a clue for the early diagnosis and treatment for HSP.
