These conditions have become increasingly common in recent years, including in children and young people. Although much is known about aspects of the pathogenesis of these diseases, the precise aetiology is not yet understood, and there remains no cure. Recent data has illustrated the importance of a number of genes-several of these are important in the onset of IBD in early life, including in infancy. Pain, diarrhoea and weight loss are typical symptoms of paediatric Crohn's disease whereas bloody diarrhoea is more typical of colitis in children. However, atypical symptoms may occur in both conditions: these include isolated impairment of linear growth or presentation with extra-intestinal manifestations such as erythma nodosum. Growth and nutrition are commonly compromised at diagnosis in both Crohn's disease and colitis. Consideration of possible IBD and completion of appropriate investigations are essential to ensure prompt diagnosis, the- reby avoiding the consequences of diagnostic delay. Patterns of disease including location and progression of IBD in childhood differ substantially from adult- onset disease. Various treatment options are available for children and adolescents with IBD. Exclusive enteral nutrition plays a central role in the induction of remission of active Crohn's disease. Medical and surgical therapies need to considered within the context of a growing and developing child. The overall management of these chronic conditions in children should include multi-disciplinary expertise, with focus upon maintaining control of gut inflammation, optimising nutrition, growth and quality of life, whilst preventing disease or treatment-related complications.展开更多

Children diagnosed with Crohn’s disease (CD) or ulcerative colitis (UC), who were followed as outpatients or during a hospitalization, participated, after informed consent was obtained from their legal representative. QOL was assessed by the IMPACT-III questionnaire. Demographic data and disease characteristics were also collected. Statistical analyses included parametric (Student’s t-test and Pearson’s r) and non-parametric (Mann-Whitney test, Fisher’s test and Spearman’s rho) procedures.RESULTSNinety-nine patients (UC: 37, 73.0% females, CD: 62, 51.6% females), aged 12.8 ± 2.6 years were included. Overall, as well as, sub-domain scores did not differ between UC and CD (overall score: 73.9 ± 13.3 vs 77.5 ± 11.2, respectively, P = 0.16). In the entire sample, total score was related to physician’s global assessment (PGA, patients classified as “mild/moderate” active disease had, on average, 14.8 ± 2.7 points lower total scores compared to those “in remission”, P < 0.001) and age at IMPACT completion (Pearson’s r = 0.29, P = 0.05). Disease activity assessed by the indices Pediatric Ulcerative Colitis activity index, Pediatric Crohn’s disease activity index or PGA was significantly associated with all subdomains scores. Presence of extraintestinal manifestations had a negative impact on emotional and social functioning domains.CONCLUSIONDisease activity is the main correlate of QOL in children with IBD, underlining the importance of achieving and sustaining clinical remission展开更多

In recent years, several studies have reported the rising incidence rate of VTE in juvenile patients with IBD, and the related risk factors have been explored.AIM To evaluate the risk of VTE in children and adolescents with IBD.METHODS Articles published up to April 2021 were retrieved from Pub Med, Embase, Cochrane Library, Web of Science, Sino Med, CNKI, and WANFANG. Data from observational studies and clinical work were extracted. The outcome was the occurrence of VTE according to the type of IBD. The available odds ratio(OR) and the corresponding 95% confidence interval(CI) were extracted to compare the outcomes. Effect size(P), odds ratio(OR), and 95%CI were used to assess the association between VTE risk and IBD disease. Subgroup analyses stratified by subtypes of VTE and IBD were performed.RESULTS Twelve studies(7450272 IBD patients) were included in the meta-analysis. Child and adolescent IBD patients showed increased VTE risk(P = 0.02, 95%CI: 0.01-0.03). Subgroup analyses stratified by IBD(ulcerative colitis(UC): P = 0.05, 95%CI: 0.03-0.06;Crohn’s disease(CD): P = 0.02, 95%CI: 0.00-0.04) and VTE subtypes(portal vein thrombosis: P = 0.04, 95%CI: 0.02-0.06;deep vein thrombosis: P = 0.03, 95%CI: 0.01-0.05;central venous catheter-related thrombosis: P = 0.23, 95%CI: 0.00-0.46;thromboembolic events: P = 0.02, 95%CI: 0.01-0.03) revealed a significant correlation between VTE risk and IBD. Patients with IBD were more susceptible to VTE risk than those without IBD(OR = 2.99, 95%CI: 1.45-6.18). The funnel plot was asymmetric, suggesting the presence of significant publication bias. Pediatric and adolescent IBD patients have an increased VTE risk. UC and CD patients exhibited a high risk of VTE. The risk of VTE subtypes was increased in IBD patients.CONCLUSION The current meta-analysis showed that the incidence and risk of VTE are significantly increased in pediatric and adolescent IBD patients. Thus, IBD might be a risk factor for VTE in children and young adults. High-quality prospective cohort studies are necessary to confirm these findings.展开更多

Deep-seated anatomic structures are difficult to assess by ultrasound technique alone. As radiation-free alternative cross-sectional imaging method, magnetic resonance imaging of the intestinal structures is costly and time-consuming. Examination of pediatric patients imply additional considerations: reduction of body motions in younger children and consideration of the most appropriate preparation, and examination technique. The demanding Sellink technique is the only means for appropriately distending the lesser intestine in order to detect small bowel strictures. Oral intake of contrast medium(CM) alone shows its limitations regarding distensibility. The need for intravenous contrast media application needs to be considered, too. Active inflammation of both intestinal wall, and mesentery can be demonstrated accurately. Nevertheless, viable alternatives to CM application is desirable, considering non-negligible adverse reactions. Recent data suggest diffusion weighted imaging might fill this diagnostic gap. Irrespective of sequence technique chosen, bowel movement remains a major obstacle. Antispasmolytics in their function as smooth muscle relaxants help in improving image quality, however, their use in children might be off-label. Optimal preparation for the examination and appropriate imaging technique allow for diagnosing typical patterns of changes in IBD, such as bowel wall thickening, ulcers, mural stratification, strictures, creeping fat, and comb sign, and lymphadenopathy. The article gives a detailed overview of current significance of magnetic resonance imaging pediatric patients suffering from IBD, considering indications, limitations, and safety aspects.展开更多

These oral manifestations may assist in the diagnosis and the monitoring of disease activity, whilst ignoring them may lead to an inaccurate diagnosis and useless and expensive workups. Indurated tag-like lesions, cobblestoning, and mucogingivitis are the most common specific oral findings encountered in CD cases. Aphthous stomatitis and pyostomatitis vegetans are among non-specific oral manifestations of IBD. In differential diagnosis, side effects of drugs, infections, nutritional deficiencies, and other inflammatory conditions should also be considered. Treatment usually involves managing the underlying intestinal disease. In severe cases with local symptoms, topical and/or systemic steroids and immunosuppressive drugs might be used.展开更多

METHODS A 16-year prospective study of IBD patients < 19 years of age was conducted in the Czech Republic(the Pilsen region). All incident IBD cases within a well-defined geographical area were retrieved from a prospectively collected computerized clinical database. Historical Czech data were used for comparison(1990-2001). Our catchment population was determined from the census data. We calculated the incidence by relating the number of newly diagnosed cases to the size of thepediatric population-at-risk in each calendar year. Age/sex, disease type, place of residence, and race/ethnicity were identified. RESULTS In total, 170 new IBD cases [105 Crohn's disease(CD), 48 ulcerative colitis(UC), and 17 IBD-unclassified(IBD-U)] were identified. The median age at IBD diagnosis was 14.2 years, 59.4% were males, and 97.1% were Caucasians. A male preponderance of IBD(P = 0.026) and CD(P = 0.016) was observed. With 109209 person-years in the catchment area, the average incidence of IBD per 100000 person-years was 10.0(6.2 for CD, 2.8 for UC, and 1.0 for IBD-U) for children aged 0 to 19 years; for those aged 0 to 15 years, the incidence rate was 7.3(4.6 for CD, 2.0 for UC, and 0.7 for IBD-U). An increase in incidence with age was observed(P = 0.0003). Over the 16-year period, the incidence increased for IBD patients(P = 0.01) and CD in particular(P < 0.0001), whereas the incidence for UC(P = 0.09) and IBD-U(P = 0.339) remained unchanged. IBD-projected data from 2016 to 2018 were 12.1, 12.3 and 12.6 per 100000 personyears, respectively.CONCLUSION Pediatric-onset IBD incidence is around its highest point. The increase, which is particularly pronounced for CD, may be challenging to relate to causes of pediatric disease.展开更多
