Correlation between the levels of NLRP3, Hcy, IL-1β, IL-18 and the prognosis in patients with hemorrhagic stroke.

OBJECTIVE To explore the connection of nucleotide-binding oligomerization domain-like receptors 3 (NLRP3), homocysteine (Hcy), interleukin-1β (IL-1β), interleukin-18 (IL-18) in peripheral blood and prognosis in patients with hemorrhagic stroke. METHODS A total of 84 patients with hemorrhagic stroke treated in our hospital were selected and divided into the good prognosis group (48 cases) and the poor prognosis group (36 cases) according to the Glasgow Prognostic Scale (GOS) at month 6 after discharge. 40 people who were matched for age, sex and risk factors for cerebral hemorrhage, but did not have cerebral hemorrhage, were selected as a control group. We detected the levels of NLRP3, Hcy, IL-1β and IL-18 in peripheral blood, and analyzed their correlation with GOS score. Then we performed Logistic regression analysis to investigate the risk factors for poor prognosis. RESULTS The expressions of NLRP3 mRNA, Hcy, IL-1β and IL-18 in peripheral blood in the poor prognosis group were higher than those in the good prognosis group (P<0.05). The expression levels of NLRP3 mRNA, Hcy, IL-1β and IL-18 were negatively correlated with GOS scores (P<0.05). Regression analysis showed that the expression of NLRP3 mRNA, serum Hcy, bleeding volume and ventricular system penetration were independent risk factors for poor prognosis. CONCLUSION In patients with poor prognosis of hemorrhagic stroke, the mRNA levels of NLRP3 and serum Hcy, IL-1β and IL-18 levels in peripheral blood elevated. High NLRP3 mRNA levels, Hcy levels, bleeding volume and ventricle system penetration are independent risk factors for poor prognosis.
