Decreased serum levels of adiponectin in subjects with autism

摘要

The neurobiological basis for autism remains poorly understood. We hypothesized that adipokines, such as adiponectin, may play a role in the pathophysiology of autism. In this study, we examined whether serum levels of adiponectin are altered in subjects with autism. We measured serum levels of adiponectin in male subjects with autism (n = 31) and age-matched healthy male subjects (n = 31). The serum levels of adiponectin in the subjects with autism were significantly lower than that of normal control subjects. The serum adiponectin levels in the subjects with autism were negatively correlated with their domain A scores in the Autism Diagnostic Interview|evised, which reflects their impairments in social interaction. This study suggests that decreased levels of serum adiponectin might be implicated in the pathophysiology of autism.
