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.
