Some of his other notable contributions have included the following: identification of the unique hemorrhagic risks associated with fetal blood sampling in the setting of alloimmune thrombocytopenia; description of the regulatory factors of the Protein C system in pregnancy; clinical use of recombinant antithrombin replacement in deficiency states; and elucidation of the subsequent health consequences of hypertensive disorders and preterm delivery. He is the principal investigator of PRESERVE-1, a multicenter, randomized, double blind, placebo controlled trial, designed to determine whether maternal administration of recombinant antithrombin improves fetal, neonatal and maternal outcomes in early onset preeclampsia.  With his support and mentoring, Dr. Paidas’ team has recently described a novel application of a non-teratogenic mood stabilizing drug that is effective in treating perinatal cytomegalovirus in preclinical models. Dr. Paidas is the Principal Investigator for an upcoming clinical trial evaluating the benefit of fibrinogen replacement in the setting of postpartum hemorrhage associated with placenta accreta.
