摘要
目的通过测定新生儿血清25-羟维生素D[25(OH)D]、甲状旁腺激素(PTH)、钙、磷浓度,了解兰州市新生儿维生素D营养状况,指导临床补充维生素D。方法选取2012年9~12月在兰州大学第一医院住院的90例新生儿为研究对象,早产儿30例,足月儿60例,采用酶联免疫法检测两组患儿生后10天内血清25(OH)D、PTH浓度,并分析两者之间的相关性;血清标本的钙、磷水平由贝克曼AU2700全自动生化分析仪测定。结果早产儿血清25(OH)D浓度为(21.9±2.5)nmol/L,显著低于足月儿(34.9±10.8)nmol/L,差异有统计学意义(P〈0.05);早产儿血清町H浓度为(94.7±40.2)pg/ml,显著高于足月儿(56.1±30.0)pg/ml,差异有统计学意义(P〈0.05),新生儿血清25(oH)D水平与明H呈负相关;旱产儿血钙浓度为(2.1±0.3)mmob/L,低于足月儿(2.3±0.3)mmol/L,差异有统计学意义(P〈0.05);早产儿血磷浓度为(1.8±0.7)mmoL/L,足月儿为(1.6±0.5)mmol/L,差异无统计学意义(P〉0.05)。结论兰州市新生儿普遍存在维生素D缺乏或不足的现象,应加强孕母和新生儿的维生素D补充。
Objective To study the nutritional status of serum 25-hydroxyvitamin D[25-(OH)D] , parathyroid hormone(PTH) , calcium and phosphorus concentration of the newborns in Lanzhou city to so as to provide reference data for the clinical practice of vitamin D supplementation. Methods Total of 90 neonates admitted to Lanzhou University First Hospital from September to December, 2012 were enrolled in the study, and the serum 25-(OH) D, PTH levels were determined with ELISA method. The correlation of 25-(OH) D and PTH was evaluated. Calcium and phosphorus concentration was measured using Beckman AU2700 automatic biochemical analyzer. Results The serum concentration of 25-(OH) D in premature infants was (21.9 ±2. 5 ) nmol/L, significantly lower than full-term infants (34. 9 ± 10. 8 ) nmol/L, P 〈 0.05. The serum concentration of PTH in premature infants was significantly higher than that of full-term infants [ ( 94. 7 ± 40. 2) pg/ml vs. ( 56. 1± 30. 0) pg/ml, P 〈 0.05 ]. 25-(OH) D and FFH were inversely correlated (P 〈 0.05). The serum concentration of calcium in premature infants was higher than that of full-term infants [ ( 2. 1± 0. 3 ) mmol/L vs. (2.3 ± 0.3 ) mmol/L, P 〈 0. 05 ]. The serum concentration of phosphorus had no statistically significant different between premature infants and full-term infants (P 〉 0. 05 ). Conclusions Vitamin D deficiency is common among newborns in Lanzhou. Vitamin D should be supplemented for pregnant women and newborns.
