The sST2 level was associated with response to treatment, 2-month survival, infection-free survival and probability of infection in SAH. Endotoxemia was weakly correlated with sST2. GRK2, a negative regulator of CXCR2, was overexpressed in PMNs of patients with SAH and cirrhosis and was decreased by IL-33. CXCR2 levels on PMNs were lower in SAH vs. cirrhosis and controls. Treatment with IL-33 partially restored CXCR2 expression in SAH and cirrhosis. PMN migration upon IL-8 was lower in patients with SAH and cirrhosis vs. controls. Treatment with IL-33 partially restored migration in those with SAH and cirrhosis.
