We investigated the association between low 25-hydroxyvitamin D (25-OHD) levels and late-onset sepsis (LOS) in preterm infants (<37 weeks). Infants with culture-proven LOS were the study group, infants without LOS were the controls. 25-OHD levels were compared between these groups. Low vitamin D was defined as 25-OHD ≤15 ng/ml. Maternal 25-OHD levels were compared to their infant's level. 108 infants were included. The study group was significantly younger (p = 0.02) with significantly lower 25-OHD levels (p < 0.001). Multivariable logistic regression analyses revealed that infants with low 25-OHD levels were 7.159 (95%CI: 1.402-36.553, p = 0.018) times more likely to develop LOS. A positive correlation was detected between maternal and neonatal 25-OHD levels for both study and control groups (r = 0.425, p = 0.009; r = 0.739, p < 0.001, respectively). Low 25-OHD levels are associated with an increased risk of developing LOS development in preterm infants.
我们研究了早产儿（<37 周）中低 25-羟维生素 D（25-OHD）水平与晚发性败血症（LOS）之间的关联。患有培养阳性 LOS 的婴儿为研究组，无 LOS 的婴儿为对照组。比较了这些组之间的 25-OHD 水平。低维生素 D 定义为 25-OHD≤15ng/ml。比较了产妇的 25-OHD 水平与其婴儿的水平。共纳入 108 名婴儿。研究组明显更年轻（p=0.02），25-OHD 水平明显更低（p<0.001）。多变量逻辑回归分析表明，25-OHD 水平低的婴儿发生 LOS 的可能性高 7.159 倍（95%CI：1.402-36.553，p=0.018）。研究组和对照组的母婴 25-OHD 水平均呈正相关（r=0.425，p=0.009；r=0.739，p<0.001）。低 25-OHD 水平与早产儿 LOS 发展的风险增加有关。
