Background/Aims The efficacy of biologics for the treatment of Crohn's disease (CD) is affected by the drug concentrations. We aimed to evaluate the importance of albumin and globulin which are known to be associated with drug concentrations as prognostic biomarkers in CD. Methods In total, 121 pediatric patients with CD who had received anti-tumor necrosis factor (TNF)-α therapy were retrospectively examined between January 2010 and February 2019. Results Relapse was observed in 48.8% of patien...

With the increasing incidence of pediatric inflammatory bowel disease (IBD) in children and its impact throughout life, transition care has become an important issue. In Korea, no guidelines have been proposed to support the transition from the pediatric clinic to the adult IBD clinic. This paper reviews the current issues related to IBD patient care during the transition from pediatrics to adults to identify the barriers and critical elements for a successful transition. Thus far, a multi-disci...

Primary intestinal lymphangiectasia (IL) can cause leakage of lymphatic fluids into the gastrointestinal tract, eventually leading to protein-losing enteropathy. A 15-year-old male patient, whose disease began at the age of 8 years, recently felt worsening general weakness. After diagnosing abnormal lymphatic lesions in the duodenum through endoscopy with biopsy and contrast-enhanced magnetic resonance lymphangiography, glue embolization of the leaking duodenal lymphatic channel was successfully...

Background/Aims : Although mucosal healing (MH) is acknowledged as the treatment target in the treat-to-target era, there are limitations on repeated endoscopic examinations, especially in pediatric patients. We aimed to investigate whether fecal calprotectin (FC) could serve as a surrogate marker for the assessment of MH in pediatric patients with Crohn's disease (CD) who have achieved sustained clinical remission (CR) while treated with anti-tumor necrosis factor (TNF) agents. Methods This mul...
