ABSTRACT

ObjectiveTo investigate the efficacy and safety of sertraline combined with low-dose aripiprazole in the treatment of obsessive-compulsive disorder in children and adolescents. MethodsA total of 62 cases pediatric patients aged 9~16 years who attended the outpatient clinic of a psychiatric hospital in Xiamen from June 2018 to May 2020 and met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for obsessive-compulsive disorder were enrolled in the study. The selected children were randomly classified into two groups for different treatments. Control group （n=30） received sertraline monotherapy， and study group （n=32） received sertraline combined with low-dose aripiprazole treatment. At the baseline and the end of the 2nd， 4th， 8th and 12th weeks of treatment， children were assessed using Children's Yale-Brown Obsessive Compulsive Scale （CY-BOCS） and Treatment Emergent Symptoms Scale （TESS）. Thereafter， the clinical efficacy and adverse reactions were compared between two groups. ResultsThe compulsive behavior dimensional score of CY-BOCS of study group was lower than that of control group at end of the 2nd and 4th weeks of treatment （t=-2.083， -2.176， P<0.05）. At the end of the 2nd week of treatment， the effective rate was 40.63% in study group， which was significantly higher than 3.33% in control group （χ2=12.317， P<0.01）. By the end of the 12th weeks of treatment， the incidence rate of side effects yielded no statistical difference between two groups （χ2=1.608， P=0.205）. ConclusionCompared with sertraline monotherapy， its combination with low-dose aripiprazole treatment can effectively accelerate the improvement of clinical symptoms in childrenand adolescents with obsessive-compulsive disorder， while the combination therapy and sertraline monotherapy have equivalent safety.
