Based on the parent report, lifetime diagnosis of anxiety or depression among children aged 6 to 17 years increased from 5.4% in 2003 to 8.4% in 2011–2012. Anxiety and depression were associated with increased risk of co-occurring conditions, health care use, school problems, and having parents with high parenting aggravation

How common are internalizing disorders in children with IBD?

• 93 children with CD: 30% of the youths reported experiencing elevated anxiety symptoms (SCARED score >20), with school anxiety, general anxiety, and separation anxiety symptoms most frequent. • Youth rated with moderate/severe disease activity self-
reported more anxiety symptoms compared with youth with inactive disease. • Greater school anxiety was associated with decreased
well-being, more abdominal pain and diarrhea • Having extraintestinal symptoms was significantly
associated with higher somatic/panic anxiety
![Page 17: Functional disorders in pediatric IBD · irritable bowel syndrome (5), functional abdominal pain (2), and functional dyspepsia (1). • Threshold for pain was lower in CD patients](https://reader033.vdocuments.site/reader033/viewer/2022043016/5f3893f9a9c66258f5329c93/html5/thumbnails/17.jpg)
374 pts (mean age 18.9 years): Mild anxiety/depressive symptoms were present in 35.2% and severe symptoms in 12.4% of patients. Elevated symptoms of either anxiety (28.3%), depression (2.9%) or both (15.8%) were found. Conclusions: psychological screening is recommended in young IBD patients. Screening facilitates early recognition and psychological treatment. Female patients and patients with active disease are the most vulnerable.

“Organification” of IBS• Increased immune activation in response to
infection and stress• Altered mucosal permeability • Sensory nerves hyperexcitability• Different microbiome• Impaired bile acid absorption• Mastcells activation

refer to this phenomenon?

TreatmentIs it better to immunosuppress a
child with IBS or to treat with cognitive behavioral interventions a child with active IBD?

Mesalamine and IBS
• Randomized, DBPC trial in 20 patients with IBS. Patients randomized to receive placebo or 800 mg mesalamine TID daily for 8 wks
• Mesalamine markedly reduced immune cells as compared with placebo (p=0.0082); this effect was ascribed to an inhibition of mastcells (p=0.0014)
• Mesalamine significantly increased general well-being (p=0.038), but had no significant effects on abdominal pain (p=0.084), bloating (p=0.177) or bowel habits

Treatment of IBS in the IBD Patient
• Education that not all symptoms are due to IBD
• Use a bio-psycho-social approach• Identify stressors?• Dietary, psychological and
behavioral therapies• Pharmacologic intervention:
Placebo, TCA, SSRI
![Page 49: Functional disorders in pediatric IBD · irritable bowel syndrome (5), functional abdominal pain (2), and functional dyspepsia (1). • Threshold for pain was lower in CD patients](https://reader033.vdocuments.site/reader033/viewer/2022043016/5f3893f9a9c66258f5329c93/html5/thumbnails/49.jpg)
Methods: 52 consecutive adult patients with Crohn's disease and 20 with ulcerative colitis who received dietary advice about the FODMAP diet. Results: Up to 70% of pts were adherent to the diet. Approximately 50% patients improved (defined as improvement of at least 5 out of 10 in overall symptoms)
Low FODMAP diet in IBDGearry RB, et al. J Crohns Colitis. 2009;3:8-14

We found no significant difference after 4 weeks in change in irritable bowel syndrome severity scores, but significant improvements in specific symptom scores and numbers reporting adequate symptom relief. The low FODMAP diet reduced fecal abundance of microbes (including Bifidobacterium adolescentis) believed to regulate the immune response, compared with the control diet, but had no significant effect on markers of inflammation.
