ABSTRACT
OBJECTIVE: Preterm birth is an important cause of infant death and morbidity but its pathophysiology still remains to be clear. The associations between preterm birth and the polymorphism of interleukin-1beta gene and interleukin-1 receptor antagonist gene have been suspected. And ethnic variations in the polymorphism of the genes were also reported. We decided to study polymorphisms of interleukin-1beta+3953 and interleukin-1 receptor antagonist in Korean pregnant women. METHODS: Patients were divided into 2 groups. Group 1 is the control group of 33 subjects with uncomplicated term delivery : group 2 is the case group of patients who had spontaneous preterm delivery. Polymorphisms were determined by polymerase chain reaction and restriction fragment length polymorphism analysis. RESULTS: There were significant differences in gestational age and birth weight between two groups (P<0.001). No significant differences were found in genotypic frequencies and allelic frequencies in interleukin-1beta+3953 between two groups. Interleukin-1 receptor antagonist gene had 5 alleles and the most frequent allele was IL1RN*1 (410bp), 66.7% in control group and 77.8% in case group. And significant differences were not found in genotypic frequencies and allelic frequencies between two groups, too. CONCLUSION: There were no significant differences in polymorphisms in interleukin-1beta +3953 and interleukin-1 receptor antagonist between term delivery group and preterm birth group.
