|a Placental abruption is an unpredictable severe complication in pregnancy. In order to investigate the possibility that the activation of the fetal nonadaptive immune system may be involved in the pathogenesis of this disease, IL-6 release from cord blood monocytes was examined by intracellular cytokine staining and flow cytometric analysis. Our results demonstrate that preterm placental abruption (n = 15) in contrast to uncontrollable preterm labor (n = 33) is associated with significantly (P < 0.001) increased release of IL-6 from the fetal monocytes. The same holds true for rhesus disease (n = 9, P < 0.001) that is characterized by a maternal production of antibodies against the rhesus-D antigen expressed by the fetal erythrocytes. This suggests that during rhesus disease, IL-6 release of monocytes is induced by antibody-mediated cross-linking of these cells to the erythrocytes in the fetal circulation. Hence, this assumption favors the idea that also in case of placental abruption, an increased maternal antibody production against paternal antigens leads to an elevated IL-6 release by the fetal monocytes. To elucidate this potential mechanism, the presence of anti-HLA-antibodies was assessed in the maternal circulation of patients with placental abruption (n = 17) and patients with uncontrollable preterm labor (n = 29). The percentage of women producing anti-paternal HLA-antibodies was significantly (P < 0.01) increased in the group of women with preterm placental abruption (47%) in comparison to women with uncontrollable preterm labor (14%). Therefore, our results suggest that an increased humoral immune response of the mother against the fetus may be decisively involved in the pathogenesis of placental abruption
