Endoscopic Balloon Dilatation in Pediatric Crohn Disease: An IBD Porto Group Study.

OBJECTIVE/BACKGROUND: Endoscopic balloon dilatation (EBD) has been shown to be effective and safe in adults with stricturing Crohn disease (CD) yet pediatric data is sparse. We aimed to assess efficacy and safety of EBD in stricturing pediatric CD. METHODS: International collaboration included 11 centers from Europe, Canada, and Israel. Recorded data included patient demographics, stricture features, clinical outcomes, procedural adverse events, and need for surgery. Primary outcome was surgery-free over 12 months and secondary outcomes were clinical response and adverse events. RESULTS: Eighty-eight dilatations were performed over 64 dilatation series in 53 patients. Mean age at CD diagnosis was 11.1 (±4.0) years, stricture length 4 cm [interquartile range (IQR) 2.8-5], and bowel wall thickness 7 mm (IQR 5.3-8). Twelve of 64 (19%) patients underwent surgery in the year following the dilatation series, at a median of 89 days (IQR 24-120; range 0-264) following EBD. Seven of 64 (11%) had subsequent unplanned EBD over the year, of whom two eventually underwent surgical resection. Two of 88 (2%) perforations were recorded, 1 of whom was managed surgically, and 5 patients had minor adverse events managed conservatively. There was a significant improvement in all clinical measures following EBD with weighted pediatric CD activity index-defined remission increasing from 13% at baseline to 44%, 46%, and 61%, and absence of obstructive symptoms in 55%, 53%, and 64% of patients at week 2, 8, and 24 respectively. CONCLUSIONS: In this largest study of EBD in pediatric stricturing CD to date, we demonstrated that EBD is effective in relieving symptoms and avoiding surgery. Adverse events rates were low and consistent with adult data.

The rising incidence of celiac disease in Scotland.

BACKGROUND AND OBJECTIVES: Although the incidence of pediatric celiac disease (CD) is increasing globally, it is uncertain whether this is attributed to improved case ascertainment or signifies a true rise. We aimed to identify all incident cases of childhood CD in southeast Scotland over the period 1990 to 2009 to assess trends in total incidence and cases diagnosed as a result of (1) a classic presentation, (2) a nonclassic presentation, or (3) targeted screening. METHODS: Twenty-year retrospective cohort study of case notes, pathology databases, endoscopy, and patient records for all children (<16 years of age) diagnosed with CD on biopsy in southeast Scotland (at-risk population of 225000-233000). Data were age-gender standardized and Poisson regression models used to calculate changes in incidence over time. RESULTS: A total of 266 children were diagnosed from 1990 to 2009 with an increase in incidence from 1.8/100000 (95% confidence interval [CI] 1.1-2.7) to 11.7/100000 (95% CI 9.8-13.9) between the epochs 1990 to 1994 and 2005 to 2009, respectively (P < .0001). The incidence of nonclassic presentation (children with a monosymptomatic presentation and those with extraintestinal symptoms) and actively screened cases increased by 1566% (P < .05) and 1170% (P < .001) from 1990 to 1999 to 2000 to 2009, respectively. However, a rise in the incidence of Oslo classic cases from 1.51/100000 (95% CI 0.91-2.38) in 1990 to 1994 to 5.22/100000 (95% CI 3.98-6.75) in 2005 to 2009 (P < .01) remained evident. CONCLUSIONS: The incidence of pediatric CD increased 6.4-fold over the 20 years. This study demonstrates that this rise is significant for classic CD, indicating a true rise in the incidence of pediatric CD.

Recognition and management of coeliac disease in children.

Coeliac disease (CD) is an immune-mediated systemic disorder elicited by the ingestion of gluten (found in wheat, rye, and barley) in genetically susceptible individuals. It affects around 1% of children and leads to proximal small bowel enteropathy, although many cases may remain undiagnosed. CD classically presents with gastrointestinal symptoms of diarrhoea, abdominal pain and weight loss, although other symptoms such as iron deficiency anaemia, faltering growth, dental enamel defects, short stature, liver disease, arthropathy, mouth ulcers, etc may be the presenting feature. Breastfeeding is considered to have a beneficial role in preventing CD or at least delays onset. Community practitioners should remain aware of the classical gastrointestinal and other features of CD and make an early referral to medical professionals. Suspicion of CD should lead to antibody screening tests and the diagnosis is confirmed by an intestinal biopsy. A gluten-free diet (GFD) should always be started by paediatric dietitians and they play a vital role in educating and supporting families. Strict adherence to a GFD is essential to maintain good health and to prevent development of long-term complications.
