Abstract
Evidence is emerging that inflammation plays a key role in the pathophysiology of ischemic stroke (IS). The aim of this study was to explore, for the first time, the relationship between IL-1β −31 T/C polymorphism and the risk of ischemic stroke (IS) among patients with type 2 diabetes mellitus (T2DM). One hundred ninety-six patients with IS (117 diabetics and 79 nondiabetics) and 192 controls were recruited to enroll in this study. IL-1β genotyping was performed by PCR-RFLP technique. After adjusting for sex, age, smoking, obesity, dyslipidemia, and hypertension, there was no significant difference in the distribution of IL-1β −31 T/C genotypes and allele frequencies between IS patients with or without type 2 diabetes mellitus and control group (p > 0.05). Moreover, a significant positive correlation between serum IL-1β level and glucose (p1 = 0.044) was showed. In addition, serum levels of IL-1β were found to be higher among TT genotype carriers than TC and CC genotype carriers in ischemic stroke patients with or without T2DM but these differences were not significant. These results indicate that IL-1β gene polymorphism might not be a risk factor in the development of ischemic stroke in Tunisian population.
