Vitamin D plays a role in central nervous system (CNS) development.

All patients were admitted at the Complex Operative Unit of Child Neuropsychiatry, Polyclinic of Bari, Italy. 25(OH)D was quantified by chemiluminescence immunoassay and level defined as: Deficiency (<20 ng/mL); insufficiency (20-30); normality (30-100); toxicity (>100).

Multivariable logistic regression analysis showed an association between ASD and Vitamin D deficiency (p=0.006). The nature of such association is unclear. Vitamin D deficiency may probably act as a risk factor for the development of ASD. Further studies are needed to unravel the role of Vitamin D in ASD etiology and investigate its therapeutic potential.

Abstract

Vitamin D plays a role in central nervous system (CNS) development. Recent literature focused on Vitamin D status in children and adolescents with autism spectrum disorder (ASD), but with inconsistent results. Our case-control study is aimed at evaluating serum 25-hydroxyl-Vitamin D (25(OH)D) concentration in children with ASD (ASD group, n=54) compared to children affected by other neurological and psychiatric disorders (non-ASD group, n=36). All patients were admitted at the Complex Operative Unit of Child Neuropsychiatry, Polyclinic of Bari, Italy. 25(OH)D was quantified by chemiluminescence immunoassay and level defined as: Deficiency (<20 ng/mL); insufficiency (20-30); normality (30-100); toxicity (>100). Statistical analysis was performed using SPSS20 (significance<0.05). The ASD group showed 25(OH)D a mean level significantly lower than control (p=0.014). Multivariable logistic regression analysis showed an association between ASD and Vitamin D deficiency (p=0.006). The nature of such association is unclear. Vitamin D deficiency may probably act as a risk factor for the development of ASD. Further studies are needed to unravel the role of Vitamin D in ASD etiology and investigate its therapeutic potential.
