Insights
Infants born to mothers with early-onset preeclampsia (PE) required more platelet transfusions, increasing risks. This study evaluated hematological parameters in very premature infants on their first day of life.
Area of Science:
- Neonatal Medicine
- Hematology
- Perinatology
Background:
- Preeclampsia (PE) is associated with hematological changes in newborns, though findings are inconsistent.
- Early-onset PE poses significant risks to maternal and neonatal health.
Purpose of the Study:
- To evaluate hematological parameters in very premature infants born to mothers with early-onset preeclampsia (PE) on day of life 1 (D1).
- To determine the correlation between these hematological parameters and neonatal morbimortality.
Main Methods:
- Retrospective study (2008-2023) at a level III NICU.
- Included preterm infants (<30 weeks gestational age).
- Compared hematological parameters on D1 between infants exposed and not exposed to PE.
Main Results:
- No significant differences in overall hematological parameters were found between groups.
- Infants exposed to PE required significantly more platelet transfusions (51.8% vs. 20.36%).
Conclusions:
- Early-onset preeclampsia exposure in very premature infants necessitates increased platelet transfusions.
- This increased need for transfusions elevates the risk of associated neonatal complications.
Objectives:
Evaluate the hematological parameters and indices in the blood count collected on the first day of life (D1) in very premature infants born to mothers with early-onset preeclampsia (PE) and their correlation with increased neonatal morbimortality.
Background:
Changes in hematologic parameters in the blood counts collected after birth associated with PE have been demonstrated by recent studies, although inconsistently.
Materials And Methods:
Retrospective study between 2008 and 2023, at a level III neonatal intensive care unit, including preterm infants with a gestational age below 30 weeks. A blood count was collected on D1 and a comparison of hematological parameters and indices was made between infants exposed or not to PE.
Results:
We included 206 newborns (PE = 39; no PE = 167). The multivariate analyses showed no significant hematological changes. PE-exposed infants required significantly more platelet transfusions (PE: n = 20 [51.8%]; no PE: n = 34 [20.36%]; P < 0.0001).
Conclusion:
PE-exposed preterms required more platelet transfusions, which increases the risk of associated complications.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
