AIM: A Belgian registry for pediatric Crohn's disease, BELCRO, was created. This first report aims at describing disease presentation and phenotype and determining associations between variables at diagnosis and registration in the database. METHODS: Through a collaborative network, children with previously established Crohn's disease and newly diagnosed children and adolescents (under 18 y of age) were recruited over a 2 year period. Data were collected by 23 centers and entered in a database. Statistical association tests analyzed relationships between variables of interest at diagnosis. RESULTS: Two hundred fifty-five patients were included. Median age at diagnosis was 12.5 y (range: 1.6-18 y); median duration of symptoms prior to diagnosis was 3 m (range: 1-12 m). Neonatal history and previous medical history did not influence disease onset nor disease behavior. Fifty three % of these patients presented with a BMI z-score < -1. CRP was an independent predictor of disease severity. Steroids were widely used as initial treatment in moderate to severe and extensive disease. Over time, immunomodulators and biological were prescribed more frequently, reflecting a lower prescription rate for steroids and 5-ASA. A positive family history was the sole significant determinant for earlier use of immunosuppression. CONCLUSION: In Belgium, the median age of children presenting with Crohn's disease is 12.5 y. Faltering growth, extensive disease and upper GI involvement are frequent. CRP is an independent predictive factor of disease activity. A positive family history appears to be the main determinant for initial treatment choice. [less ▲]

Impedance baseline is a new parameter recently related to esophageal integrity. The aim of this study was to assess the effect of different factors on impedance baseline in pediatric patients. We analyzed the impedance baseline of 800 children with symptoms of gastroesophageal reflux. Mean impedance baseline was automatically calculated throughout 24-hour tracings. The presence of different age groups and of esophagitis was evaluated. Unpaired t-test, Spearman rank correlation, polynomial, and regression plot were used for statistical analysis. Age-related percentile curves were created. We considered a P-value <0.05 as statistically significant. Impedance baseline was significantly (P < 0.001) lower in younger compared to older children up to 48 months. The mean increase of baseline per month was much higher in the first 36 months of life (47.5 vs. 2.9 Ohm in Channel 1 and 29.9 vs. 2.3 Ohm in Channel 6, respectively) than in older ages. Patients with esophagitis showed significantly decreased impedance baseline (P < 0.05). Infants (especially in the first months of life) and young children present a significantly lower impedance baseline compared to older children both in proximal and distal esophagus. The presence of esophagitis may also determine a decreased impedance baseline regardless of the age of the patients. [less ▲]

Biologicals have become an important component in the treatment of Crohn's disease in children. Their increased and long term use raises safety concerns. We describe safety and cost of infliximab in Belgian pediatric Crohn's disease patients. All patients on infliximab as part of the present or past treatment for Crohn's Disease until January 1st 2011 were selected from an existing database. Information on disease phenotype, medication and adverse events were extracted. Adverse events occurred in 25.9% of patients exposed to infliximab of which 29.6% were severe. In total 31.7% of patients stopped infliximab therapy. The main reasons for discontinuation were adverse events in 45.4% and loss of response in 30.3%. No malignancies or lethal complications occurred over this 241 patient year observation period. Immunomodulators were concomitant medication in 75% of patients and were discontinued subsequently in 38.4% of them. The cost of infliximab infusions per treated patient per year in the Belgian health care setting is approximately 9 474 euro, including only medication and hospital related costs. Even though infliximab is relatively safe in pediatric CD on the short term, close follow-up and an increased awareness of the possible adverse reactions is highly recommended. Adverse reactions appeared in 25.9% of all patients and were the main reason for discontinuation. Treatment cost has to be balanced against efficacy and modifications in disease course. In the Belgian health care system, the medication is available to all patients with moderate to severe CD. [less ▲]

Bacground and study aims : Capsule Endoscopy (CE) is a non-invasive procedure for evaluating small bowel disease. Data concerning children are scarce. The aim of the present report was to review all paediatric cases investigated by CE in Belgium. Patients and methods : The seven Belgian academic hospitals using the CE device (Given) were asked to collect information on CE performed in patients <= 18 years. Main indications for performing VCE, former radiological and endoscopic procedures were collected, as well as final diagnosis and clinical impact of VCE findings. Results : From November 2002 until December 2005, VCE was performed in 17 children (mean age : 11.9 years, range : 5-18). Indications were occult gastro-intestinal bleeding (OGIB) and/or iron deficiency anaemia (IDA) (10 cases) and chronic and/or recurrent abdominal pain (7 cases). Mean duration of symptoms was 8.6 months. The mean number of endoscopic and radiological procedures before performing CE was 4.2 per patient. Detected lesions were ulcerations (6 cases), jejunal varices (1), ileo-ileal invagination (2), active bleeding (1), and normal findings (7). In the indication of OGIB/IDA, relevant findings having an impact on the diagnosis were found in 60% of the cases. In the group with chronic and recurrent abdominal pain, CE brought relevant findings in 43%. CE findings had an impact on therapy in 44% of the patients. Conclusions : CE could be a useful tool for clinical work-up of difficult paediatric cases, not only in the indication of IDA/OGIB, but also for selected cases of recurrent abdominal pain, but prospective controlled trials including emerging techniques like CT enterography are mandatory.
