  • As a new colon-specific prodrug of 5-aminosalicylic acid (5-ASA), 5-aminosalicyl-glycine (5-ASA-Gly) was prepared by a simple synthetic route in good yield. Apparent partition coefficients of 5-ASA-Gly were lower than those of 5-ASA, which determined in$ CHCl_{3}$/pH 6.8 buffer or n-octanol/pH 6.8 buffer system. Stability of 5-ASA-Gly by peptidases was investigated by incubation of 5-ASA-Gly with the homogenates of tissue and contents of stomach, proximal small intestine or distal small intestine of rats at $37^{\circ}C$. 5-ASA was not detected, indicating that the prodrug was stable in the upper intestine. The amount of 5-ASA liberated from incubation of the prodrug in cecal or colonic contents of rats was about 65% or 27% in 8 hrs, respectively, which indicated that the prodrug activation took place more readily in the rat cecum whose bacterial counts are high like human colon. Results from in vitro experiments suggested 5-ASA-Gly as a promising candidate of a colon-specific prodrug of 5-ASA.

  • For centuries, probiotics have been known to promote health and prevent diseases. In recent times, modulation of diseases related to the immune function by probiotics has been recognized as very important to the health of the host's gut. Inflammatory bowel diseases (IBDs) are the most frequently studied diseases in which probiotic administration has been tested as a potential therapy. Various in vitro and in vivo studies have been performed. The studies discussed in this review suggest several mechanisms: probiotics could modulate the gut microflora by competing with disease-causing pathogenic bacteria and could directly regulate the mucosal immune system, which activates the innate and adaptive immune systems. In addition, human clinical trials have shown alleviation of disease symptoms of ulcerative colitis (UC), Crohn's disease, etc. This study aimed to understand the molecular mechanisms underlying immune modulation by probiotics and review studies on the functional aspect of IBD alleviation by probiotics. With more scientific studies confirming the effect of probiotics, this therapy holds promise for use in alternative medicine and/or pharmaceutical preparations, given the long history of safe consumption of probiotics.

  • Amyloidosis is a rare disease that results from the deposition of extracellular protein in various body tissues, causing progressive organ dysfunction. Secondary renal amyloidosis is a rare but serious complication of chronic inflammatory bowel disease, particularly in patients with Crohn's disease or ulcerative colitis. We report a case of secondary renal amyloidosis in a pediatric patient who reported a 16-year history of "very early onset inflammatory bowel disease". Intensive treatment including repeated infliximab infusions improved clinical parameters of inflammatory bowel disease, although renal dysfunction showed progression. Amyloidosis should be considered in patients with IBD, particularly if they suffered disease progression.

  • The Overlap syndrome is characterized by a combination of the major hepatobiliary autoimmune diseases such as autoimmune hepatitis, primary biliary cirrhosis and primary sclerosing cholangitis. It is frequently accompanied by inflammatory bowel disease. Chronic lymphoplasmacellular osteomyelitis is characterized by recurrent episodes of bacterial osteomyelitis and is associated with autoimmune diseases (especially inflammatory bowel disease). We report the case of a girl who was diagnosed with ulcerative colitis and autoimmune hepatitis at 4 years of age and with the overlap syndrome with primary sclerosing cholangitis at 6 years. At 9 years, she was diagnosed with chronic lymphoplasmacellular osteomyelitis.

  • Chronic inflammatory bowel disease (IBD) such as Crohn's disease or ulcerative colitis, affects around 2 in every 1000 individuals in western countries and its incidence, particularly amongst children, is increasing. IBD shows extreme morbidity with impact on all aspects of quality of life. If left untreated, IBD can lead to death. Conventional treatment of IBD involves powerful immunosuppressive chemotherapies and surgical intervention. Long-term anti-inflammatory medication is required and so patients are often subject to a spectrum of unpleasant side effects. Interleukin-10 (IL-10) is a cytokine that acts to suppress inflammation. When however administered by injection, the high levels of IL-10 that are distributed throughout the body also lead to side effects. Lactococcus lactis can be genetically engineered to secrete biologically active cytokines. When applied to the mucosa, these L. lactis can actively deliver such cytokines. By use of this principle we developed a new therapeutic approach for IBD. Administration of L. lactis that secretes murine IL-10 cures and prevents IBD in mice. The use of the engineered L. lactis gets around the problem of delivering IL-10, allowing dramatic reduction of the effective dose. A sincere concern exists about the possible dangers of uncontrolled, deliberate release of genetically modified microorganisms, such as could occur following application in healthcare. We engaged in the establishment of adequate means for biological growth control of engineered L. lactis by targeted gene exchange between thyA and hIL-10.

  • Dysregulation of long noncoding RNA (lncRNA) expression is linked to the development of various diseases. Recently, an emerging body of evidence has indicated that lncRNAs play important roles in the pathogenesis of inflammatory bowel diseases (IBDs), including Crohn's disease (CD) and ulcerative Colitis (UC). In IBD, lncRNAs have been shown to be involved in diverse processes, including the regulation of intestinal epithelial cell apoptosis, association with lipid metabolism, and cell-cell interactions, thereby enhancing inflammation and the functional regulation of regulatory T cells. In this review, we aim to summarize the current knowledge regarding the role of lncRNAs in IBD and highlight potential avenues for future investigation. We also collate potentially immune-relevant, IBD-associated lncRNAs identified through a built-by association analysis with respect to their neighboring protein-coding genes within IBD-susceptible loci. We further underscore their importance by highlighting their enrichment for various aspects of immune system regulation, including antigen processing/presentation, immune cell proliferation and differentiation, and chronic inflammatory responses. Finally, we summarize the potential of lncRNAs as diagnostic biomarkers in IBD.

  • Background/Aims Although functional abdominal pain disorders (FAPDs) are common in children, the accurate pathogenesis of FAPDs is not known yet. Micro-inflammation, particularly tissue eosinophilia of gastrointestinal (GI) tract, has been suggested as the pathophysiology observed in several GI disorders. We aimed to evaluate eosinophilic infiltration throughout the entire GI tract in children with FAPDs, compared to those with inflammatory bowel diseases (IBD) and to normal reference values. Methods We included 56 children with FAPDs, 52 children with Crohn's disease, and 23 children with ulcerative colitis. All subjects underwent esophagogastroduodenoscopic and colonoscopic examination with biopsies. Tissue eosinophil counts were assessed in 10 regions throughout the GI tract. Results Eosinophil counts of the gastric antrum, duodenum, terminal ileum, cecum, and ascending colon were significantly higher in children with FAPDs compared to normal reference values. Eosinophil counts of the stomach and the entire colon were observed to be significantly higher in children with IBD than in those with FAPDs. Even after selecting macroscopically uninvolved GI segments on endoscopy in children with IBD, eosinophil counts of the gastric body, cecum, descending colon, sigmoid colon, and the rectum were also significantly higher in children with IBD than those with FAPDs. Conclusions Significantly high eosinophil counts of the stomach and colon were observed in the order of IBD, followed by FAPDs, and normal controls, regardless of endoscopically detected macroscopic IBD lesions in children. This suggests some contribution of GI tract eosinophils in the intrinsic pathogenesis of FAPDs in children.

  • The incidence of pediatric-onset inflammatory bowel disease (IBD) is on the rise, accounting for up to 25% of IBD cases. Pediatric IBD often has extensive bowel involvement with aggressive and rapidly progressing behavior compared to adult IBD. Because IBD has a high morbidity rate and can have a lifelong impact, successful transition from pediatric to adult care is important to maintain the continuity of care. Furthermore, successful transition facilitates appropriate development and psychosocial well-being among patients, as well as comprehensive and harmonious healthcare delivery amongst stakeholders. However, there are various obstacles related to patients, family, providers, and organizations that interfere with successful transition. Successful transition requires a flexible and tailored plan that is made according to the patient's developmental abilities and situation. This plan should be established through periodic interviews with the patient and family and through close collaboration with other care providers. Through a stepwise approach to the transition process, patients' knowledge and self-management skills can be improved. After preparation for the transition is completed and the obstacles are overcome, patients can be gradually moved to adult care. Finally, successful transition can increase patients' adherence to therapy, maintain the appropriate health status, improve patients' self-management, and promote self-reliance among patients.

  • Objectives : To determine the effectiveness of Chuna manual therapy(CMT) for Adult Visceral Diseases. Methods : To find evidence of CMT for adult digestive system disease, we used 9 electronic databases(Pubmed, CAJ, EMBASE, Cochrane Library, Web of Science, KISS, KISTI, NDSL, RISS) up to April 2018. We reviewed randomized control trials(RCTs) using Chuna for Digestive system disease. To assess the methodological quality of each RCT, we used the Cochrane risk of bias tool. Results : We identified 11 RCTs about irritable bowel syndrome, chronic ulcerative colitis, gastritis, gastroptosis, spleen entropathy, gastrointestinal dysfunction after stroke in 356 studies. All studies used total efficiency rate for main outcome. In all studies, CMT was effective for digestive system disease. Conclusions : CMT was effective for Digestive system disease. Risk of bias was high and the difference between the experimental group and the control group was not great. Considering that there were no reports of side effects, it seems possible to apply CMT to the treatment of adult digestive system disease.
