Expressions of serum inflammatory cytokines and their relationship with cerebral edema in patients with acute basal ganglia hemorrhage.

The aim of the present study is to investigate expressions of inflammatory cytokines and their relationship with cerebral edema in the patients with acute basal ganglia hemorrhage.Between January 2015 and March 2016, 94 patients with acute basal ganglia hemorrhage admitted to our institution were included in the present study. Serum levels of interleukin (IL)-4, IL-6, IL-8 and IL-10 were measured using enzyme-linked immunosorbent assay (ELISA), and conditions of cerebral edema were evaluated using head CT upon admission, 1d after admission and 3d after admission, respectively.Serum levels of IL-4, IL-6 and IL-8 peaked 1d after admission and decreased 3d after admission with statistical significance (p <0.05); the IL-10 level was continuously increased after admission and peaked 3 days after admission with statistical significance (p<0.05). Cerebral edema was not observed in any of these patients upon admission, while occurred with a maximal edema volume 1 day after admission and the volume decreased 3 days after admission with statistical significance (p <0.05). Correlation analysis showed that levels of IL-4, IL-6 and IL-8 were positively correlated with severity of cerebral edema (r=0.324, 0286, 0.305, p <0.05 respectively), whereas IL-10 level was negatively correlated with severity of cerebral edema (r=-0.336, p <0.05).Serum levels of IL-4, IL-6 and IL-10 are positively correlated while the IL-10 level is negatively correlated with the severity of the cerebral edema in patients with acute basal ganglia hemorrhage.
