OBJECTIVE The purpose of our study was (1) to explain the relationship between levels of inflammatory cytokines and levels of hyaluronic acid in cervical mucus of pregnant women and (2) to investigate whether cytokines promote hyaluronic acid production by human cervical fibroblasts in vitro. METHODS The concentration of hyaluronic acid, interleukin-1beta, and interleukin-8 were measured in cervical mucus of pregnant women, and hyaluronic acid production by cytokine-treated (interleukin-1beta and interleukin-8) cultured fibroblasts was measured. RESULTS Hyaluronic acid concentrations in the mucus of pregnant women with threatened premature labor were higher than in mucus of normal pregnant women (P < .05). Correlations were found between hyaluronic acid concentrations and interleukin-1beta (P = .018) and interleukin-8 (P = .003) concentrations in cervical mucus. Cytokines (especially interleukin-8) stimulated hyaluronic acid production by cultured cervical fibroblasts. CONCLUSIONS Cytokines induce hyaluronic acid production by human cervical fibroblasts, which may promote cervical ripening.

D002582 Cervix Mucus A slightly alkaline secretion of the endocervical glands. The consistency and amount are dependent on the physiological hormone changes in the menstrual cycle. It contains the glycoprotein mucin, amino acids, sugar, enzymes, and electrolytes, with a water content up to 90%. The mucus is a useful protection against the ascent of bacteria and sperm into the uterus.
