Abstract
The use of oxytocin (OXT) as a biomarker of autism spectrum disorder (ASD) and
its role in the pathophysiology of ASD is still controversial and not straightforward.
Objective
To evaluate, the association of ASD risk with OXT concentration and the expression
of its receptor (OXTR) mRNA in a group of children with autism, in addition, to
investigating the influence of OXT and OXTR on the status and severity of the
disorder in the study ASD group.
Patients and methods
This study included 30 children diagnosed with ASD, representing the cases group,
and a comparable 30 neurotypical children with matched age and sex as a control
group. After detailed history taking, pedigree construction, and clinical examination
to exclude recognizable syndromes, OXT level and OXTR gene expression were
assessed in all included children.
Results and conclusion
The OXT level in autistic cases was significantly lower than in controls (P=0.0001).
Also, the fold change of OXTR was significantly lower than controls (P=0.01).
Receiver operating characteristic curve analysis showed that at a cut-off point of
less than 0.2806, OXTR showed reasonable diagnostic performance with
sensitivity, specificity, positive predictive value, and negative predictive value of
53.33, 78.2, 72.7, and 63.2, respectively (P=0.0067). At a cut-off point of less than
or equal to 119 pg/ml, the OXT level showed good diagnostic performance with
sensitivity (86.67%), specificity (76.67%), positive predictive value (78.8%), and
negative predictive value (85.2%) (P<0.0001). Our results proved the potential role
of OXT plasma measurements and gene expression in diagnosing ASD at optimal
cut-off values. These results support the use of OXT as a biomarker for ASD and
also as a possible therapeutic option to improve the social behavior of ASD children.
