IL-17 Increased in the third trimester in healthy women with term labor. Am J Reprod Immunol 2011; 65: 99–103
Introduction The function, peripheral blood expression, and physiologic importance of IL-17 is not well established. Detection of IL-17 in sera and plasma samples from patients with pre-eclampsia has been reported with inconsistent results. To establish the l levels of the IL-17 at peripheral level, we studied prospectively a cohort of 13 healthy pregnant women.
Objective To evaluate the changes in serum levels of IL-17 in healthy pregnant women in a prospective cohort.
Material and Methods Thirteen healthy pregnant women were prospectively followed to evaluate serum levels of IL-17. Each patient was evaluated at each trimester. IL-17 levels were measured by ELISA. The statistical analysis was done using repeated measures anova and Bonferroni′s multiple comparison test.
Results IL-17 levels were significantly increased from first trimester with a mean of 14.61 up to 31.78 pg/mL at third trimester (P < 0.05), but when detectable, they were almost identical range in all trimesters.
Conclusions We propose that IL-17 levels in healthy women are present with very similar range levels during the whole pregnancy but the average is increased during the third trimester maybe as a part of the complex network of cytokines as a result of implantation, fetal development, and labor process itself.
