To examine longitudinal trajectories of blood counts across pregnancy and evaluate their association with maternal complications, particularly preeclampsia, in women with essential thrombocythemia and polycythemia vera.
Longitudinal cohort study utilizing regional laboratory information systems and Danish health registries between 2010 and 2024.
Included 41 essential thrombocythemia pregnancies and 5 polycythemia vera pregnancies across 35 women.
From baseline to delivery, essential thrombocythemia pregnancies showed changes in platelet counts (−44%), hemoglobin (−5%), hematocrit (−12%), and leukocytes (+55%), while polycythemia vera pregnancies shifted by −36%, −26%, −25%, and +47%, respectively.
Maternal complications occurred in 29% of essential thrombocythemia pregnancies, with preeclampsia being the most frequent (12%).
Women with essential thrombocythemia who developed preeclampsia exhibited significantly higher pre-pregnancy platelet counts and experienced a greater gestational platelet decline compared to those without preeclampsia.

Implication

Cohort study observes distinct blood cell changes and links steep platelet drops to preeclampsia in pregnant women with thrombocythemia, suggesting utility for risk identification.
