Problem: Inflammatory changes frequently occur in cases of second trimester miscarriage or pre-term delivery, but little attention has been paid to this association with recurrent miscarriage. As interleukin-6 and interleukin-8 are inflammatory cytokines reported to be associated with bacterial vaginosis, intrauterine infections, and pre-term delivery, we here investigated whether they might have predictive value for spontaneous abortion in recurrent cases. Method of study: Cervical mucus and sera were collected at 4-5 weeks' gestation from a total of 59 patients with a history of two or more unexplained consecutive first trimester miscarriages, and examined by enzyme-linked immunosorbent assay. Patients then were followed up without medication and their pregnancy outcomes were compared with the test results. Results: Of a total of 59 patients, 13 (22%) miscarried subsequently. Both IL-6 and IL-8 in cervical mucus were significantly higher in patients who miscarried subsequently than in those who had a live birth. In addition, there was no correlation between cervical mucus and serum concentrations of IL-6 and IL-8 take at the same time, and there was no relation with serum IL-6 and IL-8 levels between the two groups. Conclusion: Cervical IL-6 and IL-8 might have predictive value for cases of recurrent miscarriage.
