Abstract: | BACKGROUND AND PURPOSE: Henoch-Sch?nlein purpura (HSP) is a small vessel vasculitis. Soluble adhesion molecules play a very important role in the immuno-inflammatory reaction of damaged vascular tissues. This study investigated the prognostic and diagnostic potential of soluble intracellular adhesion molecule-1 (sICAM-1) and vascular cell adhesion molecule-1 (sVCAM-1) in HSP. METHODS: Serum levels of sICAM-1 and sVCAM-1 were studied in 26 children with HSP. Paired blood samples (during acute and convalescent stages) were collected from 17 of the children and assayed by enzyme-linked immunosorbent assay. Correlations with clinical manifestations were examined. Seventeen healthy children served as controls. RESULTS: Both sICAM-1 and sVCAM-1 were significantly elevated at the acute stage compared with the remission stage of HSP patients versus controls (p=0.006 and p=0.0173, respectively). CONCLUSIONS: Although the levels of sICAM-1 and sVCAM-1 were not correlated with the severity of clinical manifestations in HSP, these soluble adhesion molecules may serve as diagnostic markers. |
