Disease Activity Is Associated with Obesity in Newly Diagnosed Pediatric Patients with Ulcerative Colitis.

Malnutrition and inflammatory bowel disease (IBD) are interrelated conditions. Our aim was to assess the prevalence of malnutrition, to compare anthropometric parameters in the evaluation of nutritional status in pediatric IBD, and to investigate the association between anthropometric parameters and disease activity indices (AI). Pediatric patients with newly diagnosed IBD recorded between 2010 and 2016 in the Hungarian Pediatric IBD Registry were included in this cross-sectional study. Body weight, body mass index (BMI), weight-for-height, and ideal body weight percent (IBW%) were analyzed. Pearson linear and non-linear correlations and polynomial regression analyses were performed to assess correlation between nutritional status and AI. p-values < 0.05 were considered significant. Anthropometric data of 1027 children with IBD (Crohn's disease (CD): 699; ulcerative colitis (UC): 328; mean age 13.7 years) were analyzed. IBW% identified more obese patients than BMI both in CD (7.02% vs. 2.28%) and UC (12.17% vs. 5.48%). Significant negative correlation was found among anthropometric parameters and AI in CD. In contrast, polynomial regression analysis revealed a U-shaped correlation curve between IBW% and AI in UC. Our findings show that obesity has a bimodal association with disease activity in pediatric UC. Furthermore, IBW% was more useful to identify obese pediatric patients with IBD.

Adherence to the Porto Criteria Based on the Hungarian Nationwide Pediatric Inflammatory Bowel Disease Registry (HUPIR).

Objectives: According to the Porto criteria, upper endoscopy and ileocolonoscopy with histology for patients with pediatric inflammatory bowel disease (pIBD) are recommended with small bowel imaging (SBI). We aimed to evaluate the adherence to the Porto criteria and biopsy sampling practice and to evaluate the diagnostic yield of magnetic resonance enterography (MRE) first time in a nationwide pIBD inception cohort. Methods: Newly diagnosed pIBD cases (ages 0-18 years) are registered in the prospective, nationwide Hungarian Paediatric IBD Registry (HUPIR). We analyzed the diagnostic workup of patients recorded between the 1st of January 2007 and the 31st of December 2016. Results: Data for diagnostic workup was available in 1,523 cases. Forty percent of the cases had complied with the Porto criteria. Adherence to the Porto criteria increased significantly from 20 to 57% (p < 0.0001) between 2007 and 2016. The most frequent reason for the incomplete diagnostic work-up was the lack of small bowel imaging (59%). In 2007, 8% of cases had a biopsy from all segments, and this rate reached 51% by 2016 (p < 0.0001). We analyzed the diagnostic yield of MRE in 113 patients (10.1%), who did not have any characteristic lesion for Crohn's disease. The MRE was positive for the small bowel in 44 cases (39%). Conclusions: Adherence to the Porto criteria increased significantly during the 10-year period. This is the first study that reports multiple biopsy sampling as the less accepted recommendation. The diagnostic yield of MRE in patients without characteristic lesion for Crohn's disease is 39%.

[Transfer of care of adolescent inflammatory bowel disease patients without longitudinal transition. Lesson from 10 years experiences]. / Gyulladásos bélbetegségben szenvedo gyermekek kezelésének átadása felnottszakrendelésre. 10 éves tapasztalataink összegzése.

INTRODUCTION: Transfer is a planned movement of patients and their medical records from one provider to another. Only a few data are available from real life in inflammatory bowel disease patients in this topic. AIM: Our aim was to retrospectively evaluate the results of the transfer of our patients without longitudinal transition. METHOD: Data of the transferred patients at the University of Szeged were analysed. Patients were diagnosed in paediatric care. Transfer strategy at our departments was detailed medical summary. RESULTS: 59 patients were enrolled in this study. 28.8% of the patients had mild to moderate disease activity and 71.2% was in remission at the time of transfer. Steroid therapy was initiated in 58% of the patients within an average of 9.1 months after the transfer. Anti-tumor necrosis factor therapy was given to 24% of the patients during the paediatric care and to an additional 23% in the adult care within an average of 28 months. Almost 70% of the patients received immunosuppressive therapy during paediatric and adult care. Surgery was required in 17% of the patients within an average 10.7 months after the transfer. CONCLUSION: Our results revealed that one-third of the paediatric patients have been transferred to adult care in active stage of disease. Shortly after the transfer 58% of the patients required corticosteroids and 17% surgery. Every fifth patient needed biological therapy to be initiated after the transfer. Longitudinal transition may have a potential to decrease the need for therapeutic change and the relatively high rate of surgery. Orv Hetil. 2018; 159(44): 1789-1793.

Frequency and prognostic role of mucosal healing in patients with Crohn's disease and ulcerative colitis after one-year of biological therapy.

AIM: To assess the endoscopic activity before and after a one-year period of biological therapy and to evaluate the frequency of relapses and need for retreatment after stopping the biologicals in patients with Crohn's disease (CD) and ulcerative colitis (UC). METHODS: The data from 41 patients with CD and 22 patients with UC were assessed. Twenty-four CD patients received infliximab, and 17 received adalimumab. The endoscopic severity of CD was quantified with the simplified endoscopic activity score for Crohn's disease in CD and with the Mayo endoscopic subscore in UC. RESULTS: Mucosal healing was achieved in 23 CD and 7 UC patients. Biological therapy had to be restarted in 78% of patients achieving complete mucosal healing with CD and in 100% of patients with UC. Neither clinical remission nor mucosal healing was associated with the time to restarting the biological therapy in either CD or UC. CONCLUSION: Mucosal healing did not predict sustained clinical remission in patients in whom the biological therapies had been stopped.

Incidence, Paris classification, and follow-up in a nationwide incident cohort of pediatric patients with inflammatory bowel disease.

OBJECTIVES: The aim of the study was to evaluate the incidence, baseline disease characteristics, and disease location based on the Paris classification in pediatric inflammatory bowel disease (IBD) in the Hungarian nationwide inception cohort. In addition, 1-year follow-up with therapy was analyzed. METHODS: From January 1, 2007 to December 31, 2009, newly diagnosed pediatric patients with IBD were prospectively registered. Twenty-seven pediatric gastroenterology centers participated in the data collection ensuring the data from the whole country. Newly diagnosed patients with IBD younger than 18 years were reported. Disease location was classified according to the Paris classification. RESULTS: A total of 420 patients were identified. The incidence rate of pediatric IBD was 7.48/105 (95% confidence interval [CI] 6.34/105-8.83/105). The incidence for Crohn disease (CD) was 4.72/105 (95% CI 3.82-5.79), for ulcerative colitis (UC) 2.32/105 (95% CI 1.71-3.09), and for IBD-unclassified 0.45/105 (95% CI 0.22-0.84). Most common location in CD was L3 (58.7%); typical upper gastrointestinal abnormalities (ulcer, erosion and aphthous lesion) were observed in 29.9%. Extensive colitis in patients with UC (E4, proximal to hepatic flexure) was the most common disease phenotype (57%), whereas only 5% of children had proctitis. A total of 18.6% of patients had ever severe disease (S1). Frequency of azathioprine administration at diagnosis was 29.5% in patients with CD, and this rate increased to 54.6% (130/238) at 1-year follow-up. In UC, only 3.3% received azathioprine initially, and this rate elevated to 22.5% (25/111). Use of corticosteroid decreased from 50% to 15.3% in patients with UC. Rate of bowel resection in patients with CD during the first year of follow-up was 5%. CONCLUSIONS: The incidence of pediatric IBD in Hungary was among the higher range reported. This is the first large, nationwide incident cohort analyzed according to the Paris classification, which is a useful tool to determine the characteristic pediatric CD phenotype.

Diagnostic yield of upper endoscopy in paediatric patients with Crohn's disease and ulcerative colitis. Subanalysis of the HUPIR registry.

BACKGROUND, AIMS: According to Porto Criteria upper gastrointestinal (UGI) endoscopy is recommended in patients with suspected inflammatory bowel disease (IBD). Nevertheless, previous studies revealed frequent involvement of UGI tract even in patients with ulcerative colitis (UC). The aim of the present study was to determine the diagnostic role of esophagogastroduodenoscopy (EGD) and assess the prevalence and different aspects of UGI involvement in children registered in the Hungarian Pediatric IBD Registry (HUPIR) from 1st of January 2007 to 31th of December 2009. METHODS: Twenty seven institutes provided prospective follow-up data about newly diagnosed IBD patients to HUPIR. The registry was based on detailed questionnaire (76 parameters) involving anamnestic data, laboratory findings, activity indexes, diagnostic procedures, endoscopic examinations (EGD and ileocolonoscopy), and histological data. Localization and phenotype of disease were based on the Montreal classification criteria. RESULTS: During the 3-year period 420 children were diagnosed with IBD, 265 (63%) of them had Crohn's disease (CD), 130 (31%) UC, and 25 (6%) IBD-unclassified (IBD-U). The mean age at diagnosis was 13.2 years (range: 1.2-18 years). EGD was performed in 237 patients (56%), in most cases in patients suffering from CD. Macroscopic lesions on EGD were noted in 64% of patients with CD and 40% of children with UC. Characteristic lesions for CD (ulcer, erosion, aphthous lesion, and granuloma) were noted in 31% of CD patients, however, EGD helped to establish the final diagnosis in 9% of CD patients (diagnostic yield, 9%). CONCLUSIONS: There was a high frequency of UGI involvement in children with CD and UC. One third of CD patients showed significant lesions at upper endoscopy and one patient out of ten had real diagnostic help from EGD.

[Analysis of infliximab treated pediatric patients with Crohn disease in Hungary]. / Crohn-beteg gyermekek infliximabkezelésének kezdeti tapasztalatai hazánkban.

Infliximab, the chimeric antibody to tumor necrosis factor-alpha, is indicated for medically refractory pediatric Crohn disease. Aim of our study was to examine the efficacy and side effects of infliximab therapy in Hungarian pediatric patients with Crohn disease since the authorisation of medicine for children to 31.12.2008. 23 children with refractory Crohn disease received infliximab during this period. Induction therapy with 5 mg/kg infliximab at weeks 0, 2, and 6 was introduced. 18 patients (81.8%) achieved clinical response, and 13 patients (59.1%) were in remission at the 6th week of the observation period. The evaluation was based on data of 22 children. Fistula closure rate was 70% at the at the 6th week. Two patients had acute infusion reaction, one had severe anaphilactic reaction after infliximab infusion. Chronic side effects were also observed in three cases. In our study infliximab induction therapy was effective in most pediatric patients with therapy refractory Crohn disease.
