OBJECTIVE: To investigate the frequency of the interleukin-10 (IL-10)-1082 G/A single nucleotide polymorphism in women with intrauterine fetal death (IUFD), pre-eclampsia (PE), preterm delivery (PD), and small for gestational age (SGA) infants. METHODS: In a prospective cohort study, DNA from 1,616 consecutive pregnant women was analyzed for IL-10 -1082 G/A by polymerase chain reaction. Women who developed at least one of the predefined pregnancy complications were used as cases and compared to women without pregnancy complications. RESULTS: Of 1,616 women, 254 (15.7%) developed at least one pregnancy complication. IL-10 -1082 G/A allele frequencies (G: 233/508 [45.9%] and A: 275/508 [54.1%] versus G: 1,143/2,724 [42.0%] and A: 1,581/2,724 [58.0%], respectively; p=0.10; OR 0.85; 95% CI 0.69-1.04) and genotype distributions (A/A+G/A: 201/254 [79.1%] and G/G 53/254 [20.9%] versus A/A+G/A: 1,125/1,362 [82.6%] and G/G 237/1,362 [17.4%], respectively, p=0.19; OR 0.79; 95% CI 0.54-1.15) were not significantly different between cases and controls. We observed no statistically significant difference in IL-10 -1082 G/A genotype distribution comparing controls and women with IUFD, PE, PD <37 weeks gestation, and SGA infants (<10th percentile). CONCLUSION: IL-10 -1082 G/A polymorphism is not a genetic marker for identifying women at increased risk of common pregnancy complications.
