ABSTRACT
Attention-deficit/hyperactivity disorder (ADHD) is a commonly seen mental disorder in children. Intestinal permeability may be associated with the pathogenesis of ADHD. The study herein investigated the role of gut leakage biomarkers in the susceptibility of ADHD. A total of 130 children with ADHD and 73 healthy controls (HC) individuals were recruited. Serum concentrations of zonulin, occludin, and defensin (DEFA1) were determined. Visual attention was assessed with Conners' continuous performance test (CPT). In order to rate participants' ADHD core symptoms at home and school, their parents and teachers completed the Swanson, Nolan, and Pelham-Version IV Scale (SNAP-IV), respectively. We found significantly lower DEFA1 levels in the ADHD group compared to that in the HC group (p = 0.008), but not serum levels of zonulin and occludin. The serum levels of DEFA1 showed an inverse correlation with the inattention scores in the SNAP-IV parent form (p = 0.042) and teacher form (p = 0.010), and the hyperactivity/impulsivity scores in the SNAP-IV teacher form (p = 0.014). The serum levels of occludin showed a positive correlation with the subtest of detectability in the CPT (p = 0.020). Our study provides new reference into the relation between gut leakage markers and cognition, which may advance research of the pathophysiology of ADHD.
