Abstract
OBJECTIVE
Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders among the pediatric population. Recently, neurotrophins have been suggested to be etiological factors or causes of symptoms of IBS. In the present study, the aim was to research the serum brain-derived neurotrophic factor (BDNF) and proBDNF levels in children with IBS.
METHODS
The study group was selected from pediatric gastroenterology outpatient clinic and control group was recruited from healthy children outpatient clinic. Based on the inclusion and exclusion criteria, 29 children with IBS and 55 healthy children were included in the study. The data were obtained from all participants, and if needed, from their parents. All participants were assessed in terms of anthropometric measurements. The serum (BDNF) and proBDNF levels were compared between the groups.
RESULTS
The proBDNF levels in IBS patients were higher compared with the control group in covariance analysis (IBS patients group mean 492.4, SD 534.1; control group mean 332.8, SD 406.7) (p = 0.02; Cohen's d = 0.45). The serum BDNF levels of IBS patients were also higher compared with the control group (IBS patients group mean 3.1, SD 4.3; control group mean 1.7, SD 2.7) (p = 0.02; Cohen's d = 0.51).
CONCLUSIONS
The present study is the first to demonstrate that there is a higher level of serum BDNF in children with IBS. Moreover, it is the first to demonstrate an increased level of proBDNF in IBS. Additional research is needed to confirm the preliminary results.
