Microribonucleic acid dysregulations in children and adolescents with obsessive-compulsive disorder.

ABSTRACT: AIM:Obsessive-compulsive disorder (OCD) is a disorder characterized by the presence of obsessions and/or compulsions. Although disorder etiology and pathogenesis remains unknown, several theories about OCD development have been proposed, and many researchers believe that it is caused by both genetic and environmental factors. In the current study, our aim was to investigate miRNA levels in OCD. METHODS:In the current study, we evaluated miR18a-5p, miR22-3p, miR24-3p, miR106b-5p, miR107, miR125b-5p, and miR155a-5p levels in child and adolescent OCD patients. The research sample consisted of a group of 23 OCD patients and 40 healthy volunteer controls. RESULTS:There was no significant difference in age and sex between the two groups (P>0.05). The levels of miR22-3p, miR24-3p, miR106b-5p, miR125b-5p, and miR155a-5p were significantly increased in the OCD subjects (P?0.05). There were no statistically significant differences in miR18a-5p or miR107 levels between groups (P?0.05). CONCLUSION:There could be a close relationship between levels of circulating miRNAs and OCD. If we could understand how the signaling pathways arranged by miRNAs impact on central nervous system development, function, and pathology, this understanding could improve our knowledge about OCD etiology and treatment.

Project description:BACKGROUND AND OBJECTIVES:This study examined the occurrence of sudden gains (or reversal of gains) among children with obsessive-compulsive disorder (OCD) during the course of cognitive-behavioral therapy (CBT), as well as the association of sudden gains with treatment response, treatment group, and pre-treatment clinical characteristics. METHODS:The sample consisted of 136 youth (ages 7-17) with a primary diagnosis of OCD who were randomized in a double-blinded fashion to 10 sessions of CBT with augmentation of either d-cycloserine or placebo. Sudden gain status was determined based on clinician-rated obsessive-compulsive symptom severity, which was collected on 9 occasions across the study period. RESULTS:42.6% of youth experienced at least one sudden gain, which tended to occur either after starting exposure and response prevention or towards the end of treatment. After applying the Benjamini-Hochberg procedure for multiple comparisons, there were no significant pre-treatment predictors of sudden gains and only reduced insight predicted the reversal of gains. Individuals with at least one sudden gain had improved overall treatment outcomes, measured both by reduction in OCD symptom severity, and by global illness severity. LIMITATIONS:Several clinical constructs were not examined. Symptomatology was not assessed at every treatment session. Differences in those who achieved sudden gains and those who did not may be obscured. There is the possibility that a sudden gain reflected a scoring error generated by an optimistic or inaccurate report. Finally, a relatively homogenous sample may limit the generalizability of results. CONCLUSIONS:The course of CBT for pediatric OCD is variable with many children experiencing sudden gains, but a sizable percentage experience a reversal of gains which was related to reduced insight. Sudden gains tended to occur after starting exposure and response prevention and towards the end of treatment.

Project description:BackgroundObsessive compulsive disorder (OCD) is a distressing psychiatric disorder. Traumas may trigger or aggravate OCD symptoms. COVID-19 pandemic has coursed a global crisis and has been associated with onset of psychiatric disorders in adults. Little is known about children/adolescents with OCD. The present study aimed to examine how children/adolescents with OCD react towards COVID-19 crisis.MethodsA questionnaire was distributed to two separate groups of children/adolescents. One group was a clinical group newly diagnosed at a specialized OCD clinic. All the children/adolescents had a current close contact to a therapist or doctor. The other group was a survey group identified through the Danish OCD Association. Most of these children/adolescents were diagnosed years ago, and their primary treatment was completed. For the clinical group, data from patient files was available.ResultsIn both groups, but most pronounced in the survey group, participants experienced a worsening of their OCD, anxiety, and depressive symptoms. The aggravation of OCD correlated with the worsening of anxiety, depressive symptoms, and the extent of avoidance behavior. For both groups, OCD aggressive symptoms predicted a significant worsening. Poor baseline insight showed a trend to predict a symptom worsening. The worsening was most pronounced in children with early age of onset and a family history of attention deficit hyperactivity disorder.ConclusionsTo our knowledge, this is one of the first studies examining the effect of COVID-19 in children/adolescents with OCD. The effect was examined in two separate populations strengthening the findings. The study points towards an influence of the OCD phenotype, baseline insight suggesting a continued vulnerability, and a family history of psychiatric disorders.Trial registrationThe study is approved by the Danish Data Protection Agency (1-16-02-147-20) registered 1st of April 2020. Oral and written information was given to parents and patients and written consent from patients over 15?years and parents were received.
