Abstract
Abstract
Background
Hypertensive disorders in pregnancy can cause prenatal placental perfusion with insufficient blood supply to the fetus, resulting in fetal exposure to hypoxia and leading to disturbance of neonatal hematopoietic stem cells. This study aimed to compare the hematological profiles of newborns from mothers with hypertensive disorders and normotensive delivered at the University of Gondar comprehensive specialized hospital.
Methods
A comparative cross-sectional study was conducted from March to May 2022 among 308 newborns from hypertensive and normotensive mothers in equal proportions. A systematic random sampling technique was used to select study participants. Three milliliters of cord blood were collected to perform a complete blood count by Beckman coulter. The results were presented using tables and graphs. Independent t-test and Mann-Whitney U test were done to compare the hematological profiles of the two groups. P-value < 0.05were considered statistically significant.
Results
The majority of hypertensive and normotensive mothers’ ages were between 20 and 34 years (83.77% and 90.91%, respectively). The hematocrit levels were significantly higher in neonates of hypertensive mothers than the neonates of normotensive mothers (49.10 ± 5.19% and 46.09 ± 7.63% respectively) (P < 0.001) while neutrophil counts were significantly lower in neonates of hypertensive mothers than the neonates of normotensive mothers (6.62 ± 3.30 and 7.55 ± 3.31 × 103 /ul respectively) (P = 0.007). Also, platelets counts were significantly lower in neonates of hypertensive mothers than neonates of normotensive mothers (221.25 ± 83.56 and 260.24 ± 83.01 × 103/ul respectively) (P < 0.001). The platelet and nucleated red blood cell count showed a statistically significant difference among newborns from mothers with superimposed preeclampsia and gestational hypertension.
Conclusion
Newborns delivered from hypertensive disorders of pregnancy had low white blood cell parameters, low platelet count and high red blood cell parameters compared to controls. As result, newborns may develop leukopenia, thrombocytopenia and polycythemia, respectively. Therefore, newborns should be monitored for early detection and follow-up of hematological abnormalities before complications occurred.
