维生素D3联合早期介入丹佛模式治疗幼儿孤独症谱系障碍的疗效

目的 探讨维生素D₃（VitD₃）联合早期介入丹佛模式（ESDM）对幼儿孤独症谱系障碍（ASD）的疗效。方法 选择102例1~3岁的ASD幼儿为研究对象。按家长意愿分为三组：常规康复组、ESDM组、ESDM+VitD₃组。各组幼儿治疗前及治疗3个月后进行ASD行为量表（ABC）、ASD评定量表（CARS）评估。结果 常规康复组治疗3个月后ABC总分、躯体运动能区、生活自理能区分数均降低（P < 0.05）。ESDM组治疗3个月后ABC总分、躯体运动能区、生活自理能区、交往能区、言语能区及CARS总分均降低（P < 0.05）。ESDM+VitD₃组治疗3个月后25（OH）D水平明显升高，ABC总分、生活自理能区、感觉能区、交往能区、言语能区及CARS总分均降低（P < 0.05）。ESDM组交往能区分数差显著高于常规康复组，ESDM+VitD₃组交往能区分数差高于其余两组（P < 0.05）。结论 ESDM治疗可有效改善ASD幼儿的临床症状，特别针对交往能区相比常规康复疗效显著；ESDM联合VitD₃治疗对ASD幼儿交往能力改善更优，其可能是目前改善ASD幼儿临床症状的最佳方案之一。

Clinical effect of vitamin D3 combined with the Early Start Denver Model in the treatment of autism spectrum disorder in toddlers

Objective To study the clinical effect of vitamin D3 (VitD3) combined with the Early Start Denver Model (ESDM) in the treatment of autism spectrum disorder (ASD) in toddlers. Methods A total of 102 toddlers with ASD, aged 1 to 3 years, were enrolled. According to the wishes of their parents, they were divided into conventional rehabilitation, ESDM and ESDM+VitD3 groups. Autism Behavior Checklist (ABC) and Childhood Autism Rating Scale (CARS) were used evaluate behavior problems before treatment and after 3 months of treatment. Results The conventional rehabilitation group had significant reductions in the total score and the scores on somatic movement and self-care subscales of the ABC scale after 3 months of treatment (P < 0.05). After 3 months of treatment, the ESDM group had significant reductions in the total score and the scores on somatic movement, self-care, social interaction and language subscales of the ABC scale (P < 0.05), as well as a significant reduction in the total score of the CARS (P < 0.05). After 3 months of treatment, the ESDM+VitD3 group had a significant increase in the level of 25(OH)D and significant reductions in the total score and the scores on self-care, sensation, social interaction and language subscales of the ABC scale (P < 0.05), as well as a significant reduction in the total score of the CARS (P < 0.05). The ESDM group had a significantly greater reduction in the score on social interaction subscale than the conventional rehabilitation group (P < 0.05). The ESDM+VitD3 group had a significantly greater reduction in the score on social interaction subscale than the other two groups (P < 0.05). Conclusions ESDM can effectively improve the clinical symptoms of toddlers with ASD, with a significantly better clinical effect in improving social interaction and somatic movement than conventional rehabilitation. ESDM combined with VitD3 has a significantly better clinical effect in improving social communication skills and may be one of the best strategies for improving the clinical symptoms of toddlers with ASD.
