- Abstract
Objective. To study maternal serum interleukin-17 (IL-17) during normal pregnancy and evaluate the association with preterm delivery. Design. Prospective study. Setting. Aarhus University Hospital, Denmark. Population. Three cohorts: (a) low-risk cohort of 1,069 women who had serum drawn in weeks 12 and 19, (b) subgroup of the low-risk cohort, consisting of 40 women, who had serum drawn at 12, 19, 26, 33 and 39 weeks of gestation and (c) a symptomatic cohort of 93 women admitted with symptoms of preterm delivery at a gestational age of 24+ 0 weeks to 33+ 6 weeks. Methods. Serum IL-17 determined by an in-house developed multiplex sandwich immunoassay. Main outcome measures. Preterm delivery <37+0 weeks gestation. Results. Serum IL-17 did not change during normal pregnancy. At admission to hospital, women with preterm contractions had significantly decreased serum IL-17 as compared with normal pregnancies (median <4 [interquartile ranges, IQR, <4-10 pg/ml] vs. 174 pg/ml [IQR, 92 - 485 pg/ml]); this difference was enhanced and highly significant for women delivering preterm versus term (median <4 [IQR, <4-7.9 pg/ml] vs. median 6.0 [IQR, <4-221 pg/ml]; p-value 0.03). Serum IL-17 was also lower in women with preterm prelabor rupture of membranes. A slightly, but not statistically significant decrease was found in weeks 12 and 19 in low-risk women who subsequently delivered preterm. Conclusion. Maternal serum IL-17 may be involved in preterm delivery.
