The incidence of childhood IBD in the northeastern part of the country is high and comparable with that reported from the developed western countries of Europe, and is probably still increasing. This increase may be the result of changes in the lifestyle, especially in dietary habits during the last 20 years.
Background. The aims of the study were to determine the incidence rate of pediatric inflammatory bowel disease (PIBD) and its trends for the period of 2002–2010 and to assess the geographical distribution of PIBD in Slovenia. Materials and Methods. Medical records of patients (0–18 years) with newly diagnosed IBD during the study period were retrospectively reviewed. Results. The mean incidence rate for IBD in 2002–2010 was 7.6 per 100,000 children and adolescents per year, 4.5 for Crohn's disease (CD), 2.9 for ulcerative colitis (UC), and 0.2 for IBD-unclassified, respectively. The incidence rate increased from 5.8 per 100,000 per year in 2002–2004 to 8.6 in 2005–2007 and remained stable afterwards. Statistically significant difference in the incidence rate between the Northeastern and Southwestern parts of the country was observed (p = 0.025). Conclusion. This nationwide study demonstrates that Slovenia is among the European countries with the highest PIBD incidence. During the study period a substantial rise of PIBD incidence was observed during the first half of the study and it seems to have stabilized in the second half. The significant difference in PIBD incidence between Northeastern and Southwestern parts of the country merits further exploration of the possible environmental factors.
BackgroundContrast-enhanced ultrasound (CEUS) has become an established non-invasive, patient-friendly imaging technique which improves the characterization of lesions. In addition, dynamic contrast-enhanced ultrasound (DCE-US) provides valuable information concerning perfusion of examined organs. This review addresses current applications of CEUS in children, focused on DCE-US of the bowel wall in patients with Crohn disease, which enables realtime assessment of the bowel wall vascularity with semi-quantitative and quantitative assessment of disease activity and response to medical treatment.ConclusionsCrohn’s disease is a chronic inflammatory relapsing disease. Frequent imaging re-evaluation is necessary. Therefore, imaging should be as little invasive as possible, children friendly with high diagnostic accuracy. US with wide varieties of techniques, including CEUS/DCE-US, can provide an important contribution for diagnosing and monitoring a disease activity. Even if the use of US contrast agent is off-label in children, it is welcome and widely accepted for intravesical use, and a little less for intravenous use, manly in evaluation of parenchymal lesions. To our knowledge this is the first time that the use of DCE-US in the evaluation of activity of small bowel Crohn disease with quantitative assessment of kinetic parameters is being described in children. Even if the results of the value and accuracy of different quantitative kinetic parameters in published studies in adult population often contradict one another there is a great potential of DCE-US to become a part of the entire sonographic evaluation not only in adults, but also in children. Further control studies should be performed.
Background and Aim
Acute severe colitis [ASC] is associated with significant morbidity in paediatric patients with ulcerative colitis [UC]. Most outcome studies in ASC since tumour necrosis factor alpha [TNFα] antagonists became available have focused on the first year after admission. The aim of this study was to characterise the longer-term outcomes of paediatric patients admitted with ASC.
Methods
This retrospective study was conducted in 25 centres across Europe and North America. Data on patients with UC aged <18 years, admitted with ASC (defined as paediatric ulcerative colitis activity index [PUCAI] score ≥65) between 2009 and 2011, were collected at discharge and 1, 3 and 5 years after admission. The primary outcome was colectomy-free rates at each time point.
Results
Of the 141 patients admitted with ASC, 137 [97.1%] were treated with intravenous corticosteroids. Thirty-one [22.6%] patients were escalated to second-line therapy, mainly to infliximab. Sixteen patients [11.3%] underwent colectomy before discharge. Long-term follow-up showed colectomy-free rates were 71.3%, 66.4% and 63.6% at 1, 3 and 5 years after initial ASC admission, respectively, and were similar across different age groups. Sub-analysis of colectomy rates in patients with new-onset disease [42.5% of the cohort] yielded similar results. In a multivariate analysis, use of oral steroids in the 3 months before admission, erythrocyte sedimentation rate >70 mm/h, and albumin <2.5 g/dL, were significantly associated with 5-year colectomy risk.
Conclusions
High colectomy rates were demonstrated in paediatric UC patients admitted with ASC. Additional studies are required to determine whether intensification of anti-TNFα treatment, close therapeutic drug monitoring, and use of new drugs alter this outcome.
