Interleukin-1-related genes polymorphisms in Turkish patients with Behçet disease: a meta-analysis
1Department of Rheumatology, Huadong Hospital , Fudan University, Shanghai , PR China.
Objectives:
Polymorphisms in the Interleukin (IL)-1-related genes at the locations -889, -511, + 3962 and mspa1l 1100 have been investigated for possible association with Behçet's disease (BD).
Methods:
A literature-based search was conducted to identify all relevant studies. Five independent studies from Turkish population met the included criteria.
Results:
IL-1α -889 CT [odds ratio (OR) = 0.72, 95% confidence interval (CI) = 0.55-0.95], IL-1α -889 TT (OR = 0.61, 95% CI = 0.40-0.93), IL-1β + 3962 C (OR = 1.41, 95% CI = 1.07-1.88), IL-1β + 3962 T (OR = 0.71, 95% CI = 0.53-0.94) IL-1β + 3962 CC (OR = 2.08, 95% CI = 1.08-3.99), IL-1β + 3962 CT (OR = 0.58, 95% CI = 0.38-0.88), IL-1 receptor antagonist (IL-1 Ra) mspa1l 1100 CT (OR = 0.69, 95% CI = 0.49-0.96), IL-1 Ra mspa1l 1100 TT (OR = 1.50, 95% CI = 1.08-2.08) had a significant association with BD. The pooled estimates for IL-1α -889 C, IL-1α -889 CC, IL-1α -889 T had a non-significant association with BD.
Conclusions:
IL-1α -889 CT, IL-1α -889 TT, IL-1β + 3962 C, IL-1β + 3962 T, IL-1β + 3962 CC, IL-1β + 3962 CT, IL-1 Ra mspa1l 1100 CT, IL-1Ra mspa1l 1100 TT promoter polymorphisms may confer susceptibility to BD in Turkish population.
