Paediatric Ulcerative Colitis

BACKGROUND: Inflammatory bowel disease has been linked to increasing healthcare costs, but longitudinal data on other societal costs are scarce. AIM: To assess costs, including productivity losses, in patients with prevalent Crohn's disease (CD) or ulcerative colitis (UC) in Sweden between 2007 and 2020. METHODS: We linked data from national registers on all patients with CD or UC and a matched (sex, birthyear, healthcare region and education) reference population...

BACKGROUND: The use of ustekinumab in pediatric patients with inflammatory bowel disease (IBD) is off-label and the data are limited. We conducted a systematic review evaluating the efficacy and safety of ustekinumab in pediatric IBD. METHODS: We systematically searched PubMed, EMBASE and Cochrane databases for studies of ustekinumab in children and adolescents with IBD investigating clinical remission, clinical response, corticosteroid-free (CS-free) remission, endoscopic remission/response, or safety up to March 17, 2023...

OBJECTIVES: Paediatric inflammatory bowel diseases (IBD) are chronic, idiopathic illnesses of the digestive tract, which can impact adversely on children's quality of life and burden health systems. International studies have shown these diseases are increasing. The aim was to describe paediatric IBD epidemiology across Oceania by conducting a systematic review and meta-analysis of incidence and prevalence. METHODS: Medline, Embase and Web of Science databases were searched in October 2022 for studies reporting rates of IBD, Crohn's disease (CD) or ulcerative colitis (UC) in children (≤ 19 years)...

Paediatric-onset inflammatory bowel disease (IBD) is a complex and heterogenous condition. Incidence of disease in those aged <18 years has doubled over the last 25 years, with concurrent increased prevalence and no decrease in disease severity. The tools available at diagnosis for investigation have developed over the last 10 years, including better utilisation of faecal calprotectin, improved small bowel imaging and video capsule endoscopy. Alongside this, management options have increased and include biological and small molecule therapies targeting alternative pathways (such as interleukin 12/23, integrins and Janus kinase/signal transducers and activators of transcription, JAK-STAT pathways) and better understanding of therapeutic drug monitoring for more established agents, such as infliximab...

BACKGROUND: The study aimed to assess the longitudinal impact of endoscopic healing (EH) and histological healing (HH) in a cohort of paediatric patients affected by ulcerative colitis (UC). METHODS: This was a retrospective single-centre longitudinal study. 86 children with UC who underwent endoscopic re-assessment while in clinical and biochemical remission were included. Partial EH was defined as a Mayo Endoscopic Subscore (MES) of 1 and complete EH was defined as a MES of 0...

PURPOSE: Intestinal ultrasound (IUS) is widely used as the first exam in patients with suspected inflammatory bowel disease (IBD). This study investigated the accuracy of several IUS parameters, including increased bowel wall thickening (BWT), in detecting IBD in a paediatric population. METHODS: The study included an unselected series of 113 patients aged 2-18 years (mean age 10.8 years, 65 male), referred for recurrent abdominal pain or altered bowel habits, without known organic diseases, to perform an IUS as first investigation of a diagnostic workup...

BACKGROUND AND AIMS: Ulcerative proctitis (UP) is an uncommon presentation in paediatric patients with ulcerative colitis. We aimed to characterize the clinical features and natural history of UP in children, and identify predictors of poor outcomes. METHODS: Retrospective study involving 37 sites affiliated with the IBD Porto Group of ESPGHAN. Data were collected from patients aged<18 years diagnosed with UP between 01/01/2016-31/12/2020. RESULTS: We identified 196 patients with UP (median age at diagnosis 14...

BACKGROUND: Several studies proposed models to predict disease outcomes in paediatric ulcerative colitis (UC), notably PROTECT, Schechter and PIBD-ahead, but none have been validated by external cohorts. AIM: To explore these models in a prospective multicentre inception cohort. METHODS: Children newly diagnosed with UC in 17 centres were followed at disease onset and 3 and 12 months thereafter, as well as at last visit. Outcomes included steroid-free remission (SFR) and acute severe colitis (ASC)...

BACKGROUND: Inflammatory bowel disease (IBD) is a chronic inflammatory disorder with two main subtypes: Crohn's disease (CD) and Ulcerative Colitis (UC). Prompt subtype diagnosis enables the correct treatment to be administered. Using genomic data, we aimed to assess machine learning (ML) to classify patients according to IBD subtype. METHODS: Whole exome sequencing from paediatric/adult IBD patients was processed using an in-house bioinformatics pipeline. This data was condensed into the per-gene, per-individual genomic burden score, GenePy...

BACKGROUND: People with inflammatory bowel disease (IBD) require intensive follow-up with frequent consultations after diagnosis. IBD telehealth management includes consulting by phone, instant messenger, video, text message, or web-based services. Telehealth can be beneficial for people with IBD, but may have its own set of challenges. It is important to systematically review the evidence on the types of remote or telehealth approaches that can be deployed in IBD. This is particularly relevant following the coronavirus disease 2019 (COVID-19) pandemic, which led to increased self- and remote-management...

The rising prevalence of inflammatory bowel disease (IBD) and food allergies and their partially overlapping mechanisms such as microbiome diversity reduction raise questions about the role of allergies in IBD. While data on their comorbidity are available, analysis of IgE-sensitization's influence on the clinical presentation of IBD is lacking and is the aim of this study. Histories of 292 children with newly diagnosed IBD (173 cases of ulcerative colitis, 119 cases of Crohn's disease) were analyzed. Disease age of onset, activity, location, behaviour, and anthropometric and laboratory parameters were tested for its dependence on the presence of chosen IgE sensitization markers...

BACKGROUND: Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the gold standard procedure for ulcerative colitis refractory to medical treatment, as an alternative to permanent end ileostomy. Gaining experience in pouch surgery is difficult as the procedure is performed infrequently. This study presents an institutional initiative to promote standardisation of multidisciplinary care in IPAA surgery. METHODS: A dedicated pathway for patients who had an IPAA or are considering IPAA surgery was developed among colorectal surgeons, gastroenterologists, paediatric colorectal surgeons, inflammatory bowel disease (IBD) nurses, dietitians, stoma nurses, trainees in colorectal surgery...

BACKGROUND: Current data on dual biologic therapy in children are limited. This multicenter study aimed to evaluate the effectiveness and safety of dual therapy in pediatric patients with inflammatory bowel disease (IBD). METHODS: A retrospective study from 14 centers affiliated with the Pediatric IBD Interest and Porto Groups of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition. Included were children with IBD who underwent combinations of biologic agents or biologic and small molecule therapy for at least 3 months...

Inflammatory bowel disease includes two chronic inflammatory diseases, ulcerative colitis and Crohn's disease. The burden of disease is increasing worldwide. A few reviews evaluating the paediatric use of tumour necrosis factor (TNF) antagonists have been published, although these mostly include observational studies and do not consider economic evaluations. This systematic review evaluated the available evidence regarding the efficacy, safety, and cost-effectiveness of TNF antagonist therapy for paediatric inflammatory bowel disease...

INTRODUCTION: This study describes the epidemiological, clinical, patient-reported and economic burden of inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), in Spain. METHODS: A systematic review was performed of observational studies reporting the epidemiological, clinical, patient-reported and economic burden of IBD in the Spanish population, from 2011 to 2021. Original articles and conference abstracts published in English or Spanish were eligible...

OBJECTIVES: Ustekinumab is known to be efficient in adult patients suffering from moderate to severe Crohn disease (CD) and ulcerative colitis (UC) resistant to anti-tumor necrosis factor-alpha (TNF-α). Here, we described the clinical course of treatment with ustekinumab in French pediatric inflammatory bowel disease (IBD) patients treated with ustekinumab. METHODS: This study includes all pediatric patients treated by ustekinumab injection for IBD (CD and UC), between January 2016 and December 2019...

BACKGROUND: Restorative proctocolectomy (RPC) without a defunctioning loop Ileostomy (DLI) in patients with ulcerative colitis (UC) remains controversial. AIM: To compare safety and efficacy of RPC with and without DLI in patients exclusively with UC. METHODS: A systematic review was performed according to PRISMA/MOOSE guidelines. Dichotomous variables were pooled as odds ratios (OR). Continuous variables were pooled as weighted mean differences (WMD)...

BACKGROUND AND OBJECTIVES: Renal and/or urinary manifestations (RUM) have been reported in paediatric patients with inflammatory bowel disease (IBD) but their incidence is unknown. The aims of this study were to assess the prevalence and causes of these manifestations in children with IBD and determine the causal link with 5-ASA treatment. METHODS: A retrospective observational study was performed with children with a diagnosis of IBD. All children with RUM during follow-up and/or impaired renal function (estimated glomerular filtration rate (eGFR) <90 ml/min/1...

OBJECTIVES: PERFUSE s a non-interventional study of 1233 patients (inflammatory rheumatic disease, n=496; inflammatory bowel disease [IBD], n=737) receiving infliximab (IFX) biosimilar SB2 therapy. This analysis describes response to treatment and persistence on SB2 for up to 12 months in paediatric IBD patients (n=126). METHODS: Paediatric IBD patients with Crohn's disease (CD) or ulcerative colitis (UC), either naïve or switched from originator infliximab, who started SB2 in routine practice after September 2017 were eligible...
