Objective.
To determine the second-trimester amniotic fluid concentrations of complement split products in pregnancies subsequently affected by early-onset preeclampsia.
Study Design.
Cohort of 731 women with singleton pregnancies undergoing second-trimester genetic amniocentesis followed up to delivery and analyzed as a nested case-control study.
Cases of preeclampsia developing before 34 weeks’ gestation ( n = 15 ) were compared with 47 uncomplicated term controls.
Amniotic fluid collected at amniocentesis was tested for complement split products Bb, C4a, C3a, and C5a.
Results.
Women who developed early-onset preeclampsia as compared with the term pregnant controls had significantly higher ( P = 0.04 ) median amniotic fluid C3a levels (318.7 ng/mL versus 254.5 ng/mL).
Median amniotic fluid Bb levels were also significantly higher ( P = 0.03 ) in preeclamptic women than in normal pregnant women (1127 ng/mL versus 749 ng/mL).
Median levels of C4a and C5a were not significantly different between the groups.
Conclusion.
Our data suggest that complement activation in early pregnancy is associated with early-onset preeclampsia.
We believe this to be the first prospective study to link complement activation in amniotic fluid in early pregnancy and later development of preeclampsia.
Our findings provide evidence that immune dysregulation may precede the clinical manifestations of preeclampsia and that the alternative complement pathway is principally involved.
