RESUMO
Objective: Maternal hypertension is considered a risk factor for early neonatal neutropenia. We sought to explore this relationship. Study Design: This retrospective cohort study compared initial neutrophil counts in infants born to mothers with preeclampsia with severe features (PSF) and infants born to normotensive mothers using Negative Binomial Regression (NBR) and logistic regression models. Results: Maternal hypertension negatively affected the early neonatal neutrophil count (adjusted NRB coefficient 0.4 [0.2, 0.6], p < 0.0001) but did not increase the risk of neutropenia (OR 2.07 [0.97, 4.41], p = 0.06). The initial neutrophil count and neutropenia risk were not different between PSF subgroups. Gestational age had the greatest impact on neutropenia risk (OR 0.72 [0.64, 0.81], p < 0.0001). Almost all neutropenia resolved within 48 h. Conclusion: Maternal hypertension negatively affects the early neonatal neutrophil count while not increasing the risk of neonatal neutropenia.

OBJECTIVE: To examine the relationship between maternal hypertension and early neonatal platelet counts. STUDY DESIGN: This single site retrospective cohort study compared initial platelet counts in the first day of life of infants born to mothers with preeclampsia with severe features (PSF) (n = 224) and infants born to normotensive mothers using multivariable logistic and Quasi-Poisson regression models. RESULT: There was no statistical difference in initial platelet counts or likelihood of thrombocytopenia (aOR = 1.19, 95% CI 0.68-2.08) between infants born to mothers with PSF and infants born to normotensive mothers after multivariable adjustment. Initial platelet counts and thrombocytopenia risk were unaffected by the presence of maternal end organ dysfunction. Small for gestational age (SGA) status was the most significant risk factor for the development of thrombocytopenia (aOR = 2.24, 95% CI 1.13-4.30). CONCLUSION: Maternal PSF does not directly affect neonatal initial platelet counts. SGA status confers the greatest risk of early thrombocytopenia.
