The association between plasma HMGB1 and sRAGE and clinical outcome in intracerebral hemorrhage.

High-mobility group box 1 (HMGB1) and advanced glycation end-products (RAGE) are potential mediators of inflammation. We investigate the association between levels of HMGB1 and soluble RAGE (sRAGE) following intracerebral hemorrhage (ICH) and the severity of ICH. There was a significant trend towards higher poor functional outcome rate with increasing HMGB1 and sRAGE tercile. The correlation analysis indicated that the levels of HMGB1and sRAGE were positively correlated with hematoma volume. The receiver operating curve (ROC) was 0.718 for HMGB1 and 0.631 for sRAGE to poor functional outcome. HMGB1 and sRAGE quantification provides more accurate prognostic information after ICH.
