IL1B and ischemic stroke: Our results showed that the IL-1β expression level was higher in patients with seizure recurrence than in patients without recurrence; and multivariate analysis further showed that the IL-1β expression level was independently associated with seizure recurrence after adjusting for potential confounders, i.e., the elevated IL-1β expression level could increase the risk of recurrence after the first epileptic seizure in ischemic stroke patients.
