Changes in Platelet Function in Preterm Newborns with Prematurity Related Morbidities.

Area of Science:

• Neonatal Medicine
• Hematology
• Biomarkers

Background:

• Platelet indices are crucial for assessing thromboembolic status, inflammation, and oxidative stress in preterm infants.
• Prematurity is associated with various morbidities, including respiratory distress syndrome, intraventricular hemorrhage, and anemia.

Purpose of the Study:

• To investigate changes in platelet count and function in preterm newborns with prematurity-related morbidities.
• To compare platelet indices between preterm and healthy full-term newborns.
• To evaluate the diagnostic potential of platelet volume and immature platelet fraction (IPF) as biomarkers.

Main Methods:

• Utilized flow cytometry and hematological methods for analysis.
• Measured platelet volume and immature platelet fractions (IPF) using thiazole orange staining and anti-GPIIIa antibody for gating.
• Compared findings between preterm newborns (with and without respiratory distress syndrome) and healthy full-term newborns.

Main Results:

• Preterm newborns exhibited significantly increased platelet volume compared to full-term newborns.
• CD61-TO expression was significantly lower in preterm newborns.
• Preterm infants with respiratory distress syndrome (RDS+) showed increased platelet volume and decreased IPF compared to RDS- cases.

Conclusions:

• Platelet volume and IPF show promise as diagnostic biomarkers for diseases in newborns.
• Evaluating platelet function in newborns is challenging due to limited sample volumes.
• Platelet indices offer valuable insights into the health status of preterm infants.
