目的·探讨单次高剂量肌内注射途径补充维生素D对儿童短肠综合征(short bowel syndrome,SBS)合并维生素D不足/缺乏的安全性和有效性。方法·回顾性纳入32例SBS合并维生素D不足/缺乏的儿童。当患儿血清25-羟维生素D[25-hydroxyvitamin D,25-(OH)D]浓度低于50 nmol/L时,通过肌内注射途径补充200 000 IU的维生素D2。收集患儿的临床资料(性别、年龄、原发疾病、小肠剩余长度、是否保留回盲瓣以及结肠是否完整等),记录肌内注射部位皮肤情况,以及维生素D补充前和补充后1个月的血清25-(OH)D、钙、磷和碱性磷酸酶水平状况。结果·SBS患儿入组时的中位年龄为5.0(3.0,7.0)个月。小肠闭锁和坏死性小肠结肠炎是导致SBS的主要原因(分别占28.13%和21.88%),剩余小肠平均长度为(57.27±24.55)cm。在补充维生素D之前,65.63%(21/32)的患儿存在维生素D缺乏,34.38%(11/32)的患儿存在维生素D不足。在补充维生素D之后,患儿25-(OH)D水平由28.87 nmol/L显著升高至53.10 nmol/L(P<0.001);在维生素D不足的患儿中,25-(OH)D水平从37.30 nmol/L显著升高至58.51 nmol/L(P=0.010);而在维生素D缺乏的患儿中,该水平从26.91 nmol/L显著升高至44.82 nmol/L(P<0.001);62.50%(20/32)的患儿25-(OH)D浓度达到正常水平。所有患儿在研究期间均未出现维生素D中毒、高钙血症、皮肤硬结或局部感染等并发症。结论·单次、高剂量(200 000 IU)肌内注射途径补充维生素D,可以安全、有效地改善SBS合并维生素D不足/缺乏婴儿的维生素D水平。

Objective ·To explore the safety and efficacy of a single high-dose intramuscular injection of vitamin D in children with short bowel syndrome (SBS) complicated by vitamin D insufficiency/deficiency. Methods ·The retrospective study included 32 children with SBS complicated by vitamin D insufficiency/deficiency. When the serum 25-hydroxyvitamin D [25-(OH)D] concentration was lower than 50 nmol/L, a single intramuscular injection of 200 000 IU vitamin D2 was administered. Clinical data, including gender, age, primary disease, remaining length of the small intestine, presence of the ileocecal valve, and colonic integrity, were collected. Skin conditions at the intramuscular injection site and the levels of serum 25-(OH)D, calcium, phosphorus, and alkaline phosphatase before and one month after vitamin D supplementation were recorded. Results ·The median age at enrollment was 5.0 (3.0, 7.0) months. Intestinal atresia and necrotizing enterocolitis were the main causes of SBS, accounting for 28.13% and 21.88%, respectively. The average length of the remaining small intestine was (57.27±24.55) cm. Before vitamin D supplementation, 65.63% (21/32) of children had vitamin D deficiency and 34.38% (11/32) had vitamin D insufficiency. After supplementation, serum 25-(OH)D levels increased significantly compared with baseline (53.10 nmol/L vs. 28.87 nmol/L, P<0.001). In children with vitamin D insufficiency, the serum 25-(OH)D levels increased from 37.30 nmol/L to 58.51 nmol/L (P=0.010), while in those with vitamin D deficiency, the levels increased from 26.91 nmol/L to 44.82 nmol/L (P<0.001). Overall, 62.50% (20/32) of children achieved normal serum 25-(OH)D levels. Moreover, no complications, including vitamin D toxicity, hypercalcemia, skin induration, or local infection, were observed in any of the children. Conclusion ·A single high-dose (200 000 IU) intramuscular injection of vitamin D can safely and effectively improve the vitamin D level in children with SBS complicated by vitamin D insufficiency/deficiency.
