[Circulating immune complexes in women with prolonged pregnancy].

The authors examined 90 pregnant women, divided into three groups: pregnant women at 39-40 weeks gestation, parturients and women with prolonged pregnancy. Circulating immune complexes were determined. Differences in the three groups were statistically significant. The lowest level of circulating immune complexes was found in women with prolonged pregnancy, but the highest--in parturients. Inferences are made for the significance of circulating immune complexes for the onset of delivery and development of postmaturity.
