PROBLEM: To investigate the expression of complement activation factors in plasma of patients with early/late-onset severe pre-eclampsia.
METHODS: A case-control study was performed. The study group consisted of 30 cases of early-onset severe pre-eclampsia (EOSPE) and 30 cases of late-onset severe pre-eclampsia (LOSPE). Thirty cases were selected as the early-onset control group (E-control) and 30 as the late-onset control group (L-control). ELISA was used to test C1q, C4d, MBL, Bb, C3a, C5a, and MAC in the maternal peripheral circulation.
RESULTS: The complement activation factors Bb, C3a, C5a, and MAC were increased significantly in EOSPE (all P<.01) and LOSPE (P value: .027, <.001, .001, and <.001, respectively) compared with E/L-control. C1q and C4d were increased significantly in LOSPE (P value: .003 and .014, respectively) compared with L-control.
CONCLUSION: Abnormal activation of the complement system exists in the maternal circulation of patients with early- and late-onset severe pre-eclampsia. In patients complicated with LOSPE, the complement system was activated through both the classical and alternative pathways, while in EOSPE, the complement system was activated mainly through the alternative pathway.
