Background: No medications are currently approved for the treatment of nonmonogenic, nonsyndromic obesity in children younger than 12 years of age. Although the use of liraglutide has been shown to induce weight loss in adults and adolescents with obesity, its safety and efficacy have not been established in children.

Methods: In this phase 3a trial, which consisted of a 56-week treatment period and a 26-week follow-up period, we randomly assigned children (6 to <12 years of age) with obesity, in a 2:1 ratio, to receive either once-daily subcutaneous liraglutide at a dose of 3.

Background: Exploratory analysis to determine the effect of semaglutide versus comparators on high-sensitivity C-reactive protein (hsCRP) in subjects with type 2 diabetes.

Methods: Trials of once-weekly subcutaneous (SUSTAIN 3) and once-daily oral (PIONEER 1, 2, 5) semaglutide with hsCRP data were analyzed. Subjects with type 2 diabetes (N = 2482) received semaglutide (n = 1328) or comparators (placebo, n = 339; exenatide extended-release, n = 405; empagliflozin, n = 410).

Background: The long-term management of irritable bowel syndrome (IBS) poses many challenges. In short-term studies, eHealth interventions have been demonstrated to be safe and practical for at-home monitoring of the effects of probiotic treatments and a diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs). IBS has been linked to alterations in the microbiota.

Background: Little is known about the consequences of intrauterine exposure to, and the post-natal clearance of, vedolizumab.

Aims: To investigate the levels of vedolizumab in umbilical cord blood of newborns and rates of clearance after birth, as well as how these correlated with maternal drug levels, risk of infection and developmental milestones during the first year of life METHODS: Vedolizumab-treated pregnant women with inflammatory bowel disease were prospectively recruited from 12 hospitals in Denmark and Canada in 2016-2020. Demographics were collected from medical records.

Objective: Microscopic colitis [MC], encompassing collagenous colitis [CC] and lymphocytic colitis [LC], is an increasingly prevalent gastrointestinal disease with an unknown aetiology. Previous research has reported significant differences in the incidence of MC within Denmark, with the lowest incidence found in the most populated region [Capital Region of Denmark]. Our aim was to elucidate the causes of these regional differences.

Background & Aims: The Lémann Index is a tool measuring cumulative structural bowel damage in Crohn's disease (CD). We reported on its validation and updating.

Methods: This was an international, multicenter, prospective, cross-sectional observational study.

Background: Costs of using eHealth in inflammatory bowel disease (IBD) management has only been assessed for short follow-up periods. The primary aim was to compare the direct costs of eHealth (cases) relative to standard care (matched controls) for IBD during three years of follow-up.

Methods: The study design was a retrospective, registry-based follow-up study of patients diagnosed with IBD two years prior, and three years subsequent, to their enrolment in eHealth.

Background: The risk of colorectal cancer (CRC) for patients with inflammatory bowel disease (IBD) has previously been investigated with conflicting results. We aimed to investigate the incidence and risk of CRC in IBD, focusing on its modification by treatment.

Methods: All patients with incident IBD (n = 35,908) recorded in the Danish National Patient Register between 1997 and 2015 (ulcerative colitis: n = 24,102; Crohn's disease: n = 9739; IBD unclassified: n = 2067) were matched to approximately 50 reference individuals (n = 1,688,877).

Background And Aims: The disease course of microscopic colitis [MC], encompassing collagenous colitis [CC] and lymphocytic colitis [LC], is not well known. In a Danish nationwide cohort, we evaluated the disease activity patterns as well as the risk of colorectal cancer [CRC] and mortality based on disease severity.

Methods: All incident MC patients [n = 14 302] with a recorded diagnosis of CC [n = 8437] or LC [n = 5865] in the Danish Pathology Register, entered between 2001 and 2016, were matched to 10 reference individuals [n = 142 481].

Background/aim: Microbial dysbiosis in inflammatory bowel disease (IBD) is poorly understood. Faecal samples collected for the purposes of microbiota analysis are not yet a part of everyday clinical practice. To explore associations between faecal microbiota and disease activity measures in adult IBD patients, for the purpose of possibly integrating microbiota measures in an existing IBD eHealth application for disease-monitoring.

Background And Aims: Epidemiological studies suggest an increasing global incidence of microscopic colitis, including collagenous colitis and lymphocytic colitis. We aimed to investigate the incidence and prevalence of microscopic colitis in Denmark.

Methods: In a nationwide cohort study, we included all incident patients with a recorded diagnosis of collagenous colitis or lymphocytic colitis in the Danish Pathology Register between 2001 and 2016.

Background: The optimal way to home-monitor patients with inflammatory bowel disease (IBD) for disease progression or relapse remains to be found.

Aim: To determine whether an electronic health (eHealth) screening procedure for disease activity in IBD should be implemented in clinical practice, scheduled every third month (3M) or according to patient own decision, on demand (OD).

Methods: Adult IBD patients were consecutively randomized to 1-year open-label eHealth interventions (3M OD).

Background: Few studies have examined the association between inflammatory bowel disease (IBD) and Parkinson's disease (PD).

Methods: To estimate the incidence and relative risk of PD development in a cohort of adult IBD, we included all incident IBD patients (n = 39,652) in the Swedish National Patient Register (NPR) between 2002 and 2014 (ulcerative colitis [UC]: n = 24,422; Crohn's disease [CD]: n = 11,418; IBD-unclassified [IBD-U]: n = 3812). Each IBD patient was matched for sex, age, year, and place of residence with up to 10 reference individuals (n = 396,520).

The Natural History of IBD: Lessons Learned.

Curr Treat Options Gastroenterol

March 2018

Purpose Of Review: Inflammatory bowel diseases (IBD), which include Crohn's disease (CD) and ulcerative colitis (UC), are chronic, relapsing diseases with unknown etiologies. The purpose of this review is to present the natural disease course evidenced in the latest epidemiology data.

Recent Findings: The prevalence of IBD is rapidly increasing, affecting five million patients worldwide with the highest incidence observed in Northern Europe and Northern America.

Purpose Of Review: The aim of this study is to review the basic concepts of electronic health (eHealth), with a focus on its nutritional applications and its usefulness for digestive diseases.

Recent Findings: eHealth applications for the treatment and monitoring of digestive disease are growing in number. ehealth helps patients in coping with their disease by promoting self-management, which increases adherence to medical treatment and diets, and leads to an improved quality of life.

Inflammatory bowel diseases (IBDs), due to their chronic and progressive nature, require lifelong treatment to relief and/or prevent inflammation and symptoms, obtaining mucosal healing at best. Therefore, adherence to treatment is an essential topic to address when treating patients with IBD. Nonetheless, adherence remains a common and complex issue in IBD care.
