To examine the relationship between maternal hypertension and early neonatal platelet counts.
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.
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).
Maternal PSF does not directly affect neonatal initial platelet counts. SGA status confers the greatest risk of early thrombocytopenia.
探讨母亲高血压与新生儿早期血小板计数之间的关系。
这项单中心回顾性队列研究，采用多变量逻辑回归和拟泊松回归模型，比较了患有重度子痫前期（PSF）的母亲所生婴儿（n = 224）与血压正常的母亲所生婴儿出生第一天的初始血小板计数。
多变量调整后，患有PSF的母亲所生婴儿与血压正常的母亲所生婴儿在初始血小板计数或血小板减少的可能性方面无统计学差异（调整后比值比[aOR]=1.19，95%置信区间[CI]为0.68 - 2.08）。母亲终末器官功能障碍的存在并不影响初始血小板计数和血小板减少风险。小于胎龄（SGA）状态是发生血小板减少的最显著危险因素（aOR = 2.24，95% CI为1.13 - 4.30）。
母亲PSF不会直接影响新生儿的初始血小板计数。SGA状态是早期血小板减少的最大风险因素。
