Crohn ' s disease (CD)와 ulcerative colitis (UC)의 원인은 아직 확실하지 않다. 확립된 연구보고는 없으나 여러 가지 세균이나 바이러스가 원인일수도 있고, 장내세균이 증강인자일수도 있다. 또한, 서양식 식사도 장 점막의 상태와 점막투과성에 영향을 미치기 때문에 역시 증강인자라고 할 수 있다. 각가지의 생활습관도 inflammatory bowel disease (IBD) 발병에 영향을 미치는 요인으로 알려져 있지만, 이들에 대한 다 기능성인자를 규명하는 것은 아직 많은 기초적 연구가 필요하다.

Purpose: The evidence for an association between inflammatory bowel disease (IBD) and obesity is conflicting. Therefore, we set out to review the body mass index (BMI) at presentation of IBD to understand if the rise of the obesity rate in the general population, lead to an increase of obesity in patients with IBD at the time of diagnosis. Methods: Retrospective review of all patients with IBD seen at Children's Hospital and Medical Center from January 1st 2010 to December 31st 2014. From the initial visit and endoscopy, we obtained: age; sex; BMI; disease phenotype; disease severity. Results: We had a total of 95 patients, 35 patients were excluded due to incomplete data or referral being made after diagnosis was made. 28 were males and 32 were females, Age range was 2-17 years. A 37 had Crohn's disease, 19 ulcerative colitis, and 4 indeterminate colitis. Disease severity in 19 cases was mild, 29 moderate and 12 severe. BMI distribution was as follows-obese (5.0%), overweight (6.7%), normal weight (65.0%), mild malnutrition (8.3%), moderate malnutrition (15.0%), severe malnutrition (1.7%). Conclusion: Our data is consistent with other series. Showing most children had a normal BMI, regardless of disease severity or phenotypes. One confounding factor is the possibility of delay in referral to GI. This could mean some obese children may fall in the normal BMI range at the time of diagnosis due to ongoing weight loss. Future studies should include prospective cohort studies, comparing incidence of IBD in obese and non-obese patients, severity at presentation, duration of symptoms, and clinical outcomes.

Inflammatory bowel disease (IBD) is defined as a chronic inflammatory-mediated disease that causes ulceration and inflammation in the gastrointestinal tract. Among most patients, the course of chronic inflammation repeatedly shows intermittent exacerbations and alternating remissions. However, despite the various therapeutic options to relieve symptoms, such as corticosteroids, TNF-α inhibitors, and antibiotic drugs, there is no known cure for IBD. Nonetheless, previous research has revealed that the autonomic nervous system is involved in the pathophysiology of IBD. In this study, we reviewed clinical trials confirming the therapeutic effect of vagus nerve stimulation (VNS) on IBD in vivo. We searched in vivo and human studies on Pubmed using keywords combined with "vagus nerve stimulation", "VNS", and "inflammatory bowel disease". All studies included in this review reported that direct VNS is effective in relieving symptoms of IBD and has no severe adverse effects. The most frequently stimulated site was the unilateral cervical vagus nerve area, and parameters for stimulation were set as 5-20 Hz. Based on the results, we aim to summarize the evidence for the efficacy of VNS on IBD and suggest the possibility of auricular electroacupuncture treatment as a therapeutic option for IBD.

Purpose: This study aimed to identify clinical characteristics of South Korean pediatric inflammatory bowel disease (IBD) in a children's hospital over the past 5 years, with a specific focus on comparing the features observed between Crohn's disease (CD) and ulcerative colitis (UC). Additionally, it aimed to examine the nursing diagnoses given to patients. Methods: This retrospective study analyzed the medical records of Korean pediatric patients under 18 years of age who were diagnosed with IBD and hospitalized at a children's hospital in Seoul, South Korea, from January 2017 to December 2021. Results: The number of pediatric patients diagnosed with IBD steadily increased. This finding was particularly prominent for CD patients, the majority of whom were male. Pediatric patients with CD had significantly higher rates of abdominal pain and perianal lesions, while pediatric patients with UC had a higher rate of bloody stool. Laboratory findings indicated that CD patients had higher levels of inflammatory markers and lower albumin levels than UC patients. The nursing diagnoses given during hospitalization mostly related to safety and protection, physical comfort, and gastrointestinal function. Conclusion: This study provides insights into Korean pediatric IBD patients, enabling early detection and the development of nursing intervention strategies. From a comprehensive perspective, nursing care should not only address patients' physical needs but also their psychosocial needs.

Purpose: Monogenic inflammatory bowel disease (IBD) patients do not respond to conventional therapy and are associated with a higher morbidity. We summarized the clinical characteristics of monogenic IBD patients and compared their clinical outcomes to that of non-monogenic IBD patients. Methods: We performed a retrospective cohort study of all children <18 years old who were diagnosed with IBD between 2005 and 2016. A total of 230 children were enrolled. Monogenic IBD was defined as a presentation age less than 6 years old with confirmation of a genetic disorder. We subdivided the groups into monogenic IBD (n=18), non-monogenic very early-onset IBD (defined as patients with a presentation age <6 years old without a confirmed genetic disorder, n=12), non-monogenic IBD (defined as all patients under 18 years old excluding monogenic IBD, n=212), and severe IBD (defined as patients treated with an anti-tumor necrosis factor excluding monogenic IBD, n=92). We compared demographic data, initial pediatric Crohn disease activity index/pediatric ulcerative colitis activity index (PCDAI/PUCAI) score, frequency of hospitalizations, surgical experiences, and height and weight under 3rd percentile among the patients enrolled. Results: The initial PCDAI/PUCAI score (p<0.05), incidence of surgery per year (p<0.05), and hospitalization per year (p<0.05) were higher in the monogenic IBD group than in the other IBD groups. Additionally, the proportion of children whose weight and height were less than the 3rd percentile (p<0.05 and p<0.05, respectively) was also higher in the monogenic IBD group. Conclusion: Monogenic IBD showed more severe clinical manifestations than the other groups.

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.

Background: Commensal bacteria play an important role in the pathogenesis of inflammatory bowel disease (IBD) and probiotics have been used as treatment options. We aimed to explore the current use of probiotics and factors associated with their prescription in patients with IBD. Methods: This cross-sectional study was conducted on a single hospital-based cohort. Patients were eligible if they were ≥18 years old, visited the IBD clinic as an outpatient more than twice during the study period, and had a confirmed diagnosis of IBD. Patients were divided into two groups based on the prescription of probiotics. Clinical assessments were compared between the two groups. Results: In total, 217 patients were enrolled in this study. In patients with Crohn disease (CD), moderate or severe abdominal pain; prior use of methotrexate (MTX), iron, thiopurines, or biologics; history of IBD-related surgery; and stool frequency were independently associated with the prescription of probiotics. In patients with ulcerative colitis (UC), moderate or severe abdominal pain, hematochezia, stool frequency, and moderate or severe physician global assessment score were independently associated with the prescription of probiotics. Conclusion: Increased disease activity may be associated with fewer prescriptions of probiotics in patients with IBD. However, physicians prescribed probiotics to control symptoms, such as abdominal pain and increased stool frequency in patients with UC and CD, and hematochezia in patients with UC. Additionally, the use of MTX and iron, and a history of IBD-related surgeries were associated with more frequent probiotic prescriptions in patients with CD.

Ulcerative colitis and Crohn's disease are a set of chronic, idiopathic, immunological and relapsing inflammatory disorders of the gastrointestinal tract referred to as inflammatory bowel disorder (IBD). Although the etiological factors involved in the perpetuation of IBD remain uncertain, development of various animal models provides new insights to unveil the onset and the progression of IBD. Various chemical-induced colitis models are widely used on laboratory scale. Furthermore, these models closely mimic morphological, histopathological and symptomatical features of human IBD. Among the chemical-induced colitis models, trinitrobenzene sulfonic acid (TNBS)-induced colitis, oxazolone induced-colitis and dextran sulphate sodium (DSS)-induced colitis models are most widely used. TNBS elicits Th-1 driven immune response, whereas oxazolone predominantly exhibits immune response of Th-2 phenotype. DSS-induced colitis model also induces changes in Th-1/Th-2 cytokine profile. The present review discusses the methodology and rationale of using various chemical-induced colitis models for evaluating the pathogenesis of IBD.

Inflammatory bowel disease (IBD) is a chronic inflammatory disorder on the large intestine that has been considered as an incurable not only in Western society but also in Eastern Asia in recent years. Despite enormous efforts to develop novel therapeutics for this disease, strategy using bioactive compounds from natural product is still considered as important. p-hydroxycinnamic acid (HCA) is an intermediate substance found in several plants and has been known to possess anti-inflammation but little evidence is reported whether HCA has an inhibitory effect on intestinal inflammation. In the present study, we observed HCA does not show cytotoxic and apoptotic in HT-29 cells. Quantitative PCR analysis revealed that HCA effectively blocks the activity of HT-29 cells stimulated with TNF-α treatment. HCA inhibits translocation of p65 and MAPK pathways in activated HT-29 cells by TNF-α treatment. Besides, oral administration of HCA attenuates manifestation of DSS-induced inflammatory disease in vivo. Histological analysis exhibited that oral administration of HCA recovers IBD symptoms. The expression of pro-inflammatory cytokines were reduced by oral administration of HCA on intestinal tissues. Therefore, these results suggest that HCA has a potent anti-inflammatory effect on intestinal cells as well as show a therapeutic potential for treating IBD in vivo.
