维生素D缺乏与新生儿早发型败血症的相关性研究

Relationship between vitamin D deficiency and early-onset neonatal sepsis

摘要:

目的 评估血清维生素D水平对足月新生儿早发型败血症 （EOS）的影响。方法 78例足月EOS新生儿设为研究组 （EOS组），60例无感染相关临床和/或实验室表现的健康足月新生儿设为对照组。两组新生儿及其母亲均在产后72 h内采血进行25-羟基维生素D （25-OHD）水平检测，比较两组新生儿维生素D缺乏发生率及母亲孕期维生素D补充情况。结果 两组母亲和新生儿之间血清25-OHD水平均呈显著正相关 （EOS组：r = 0.797，P < 0.01，对照组：r = 0.929，P < 0.01）。EOS组新生儿及其母亲血清25-OHD水平显著低于对照组 （P < 0.01）。EOS组新生儿维生素D缺乏发生率显著高于对照组 （P < 0.01），而母亲孕末期3个月补充足量维生素D的比率显著低于对照组 （P < 0.01）。结论 低血清25-OHD水平与足月新生儿EOS的发生具有相关性。

Abstract:

Objective To evaluate the effect of vitamin D level on early-onset sepsis (EOS) in neonates. Methods Seventy-eight full-term neonates with EOS were used as the research group (EOS group). sixty healthy fullterm neonates without clinical and/or laboratory features related to infections were used as the control group. Blood samples of the neonates and their mothers in both groups were collected within 72 hours of delivery to determine 25-hydroxyvitamin D (25-OHD) levels. The rate of vitamin D deficiency in the neonates and the level of 25-OHD supplemented to their mothers during pregnancy were compared between the two groups. Results There was a significant positive correlation between the serum level of 25-OHD of the mothers and that of the neonates in both groups (EOS group:r = 0.797, P < 0.01; control group:r = 0.929, P < 0.01). The neonates and their mothers in the EOS group had significantly lower 25-OHD levels than those in the control group (P < 0.01). The rate of vitamin D deficiency among the neonates in the EOS group was significantly higher than that of the control group (P < 0.01). The level of vitamin D supplemented to the mothers during the last 3 months of pregnancy in the EOS group was significantly lower than that in the control group (P < 0.01). Conclusions Low serum level of 25-OHD is associated with the development of earlyonset sepsis in full-term neonates.
