[Effect of interleukin 6 on uterine contractility in the human in vivo]

The influence on uterine contractility of inflammatory cytokines like interleukin-6 is widely unknown. We were able to demonstrate in 16 human myometrial strips obtained during caesarean section in the organ chamber a highly significant (P < 0.001) increase of the activity of uterine strips after addition of IL-6. This further emphasizes the importance of subclinical infections for the etiology of so called idiopathic preterm labour.
