Consideration of the clinical manifestations of severe preeclampsia (PE) and HELLP syndrome in the context of thrombotic microangiopathy allows a fresh look at the pathogenesis of these gestational complications. There is new evidence for a similar mechanism for endothelial damage in severe PE, HELLP syndrome, and atypical hemolytic uremic syndrome (aHUS), which is realized due to the excessive activation of the alternative complement pathway. An investigation of the role of complement factors in the pathogenesis, course and progression of PE with realization in the HELLP syndrome will be able to further consider them as markers for predicting severe PE complications.
