AbstractAbstract PDFPubReaderePub
One of the most common complications of Crohn’s disease (CD) is the formation of strictures. Endoscopy plays a vital role not only in the diagnosis, differential diagnosis, and disease monitoring of CD, but also the delivery of effective treatment. The purpose of this review is to update the endoscopic management of strictures in CD. Endoscopic therapy has provided minimally invasive treatment for CD. Commonly used endoscopic treatment modalities include balloon dilation, endoscopic stricturotomy, endoscopic strictureplasty, and endoscopic stenting. The pros and cons of these endoscopic treatment modalities are discussed.

Inflammatory bowel diseases
Pediatric to adult inflammatory bowel disease transition: the Asian experience
Bernice Tan, David Ong
Intest Res 2020;18(1):11-17.   Published online January 30, 2020
DOI: https://doi.org/10.5217/ir.2019.09144
AbstractAbstract PDFPubReaderePub
Many tertiary inflammatory bowel disease (IBD) centers recognize that a structured transition program is fundamental for an IBD unit. However, the path to ensuring a seamless transition for all stakeholders is often fraught with challenges. In this review, we go through current evidence, identify the requirementsof a successful transition program, and the barriers to seamless transfer. We also aim to shed light on differences in needs between the Western and Asian adolescent IBD populations. Majority of healthcare providers viewed having a structured transition program to be very important. The lack of a standard protocol led us to come up with a list of requirements ofa successful program. These include: multidisciplinary team meetings, alternating visits between the adultand pediatric clinics, proper documentation of records, and determining the ideal timing for transfer. The difficulties forthe Asian adolescent IBD population may be attributed to the reliance on parental support to make decisions regarding medicaltreatment. Lastly, there are various physician, patient and disease factors which are barriers to seamless transition. These includethe lack of proper documentation, and lack of patient self-efficacy. We also propose a standardized template for documentation of medical records for IBD patients.

AbstractAbstract PDFPubReaderePub
The treatment of inflammatory bowel disease (IBD) has been revolutionized for the last 10 years by the increasing use of immunomodulators and biologics. With immunosuppression of this kind, opportunistic infection is an important safety concern for patients with IBD. In particular, viral hepatitis is determined by the interaction between the virus and the host’s immunity, and the risk of reactivation increases if immunity is compromised by immunosuppression therapy. Parts of Asia, including Korea, still show intermediate endemicity for the hepatitis A virus and hepatitis B virus compared with the United States and Western Europe. Thus, members of IBD research group of the Korean Association for the Study of Intestinal Diseases have produced a guideline on the prevention and management of viral hepatitis in IBD.

Biosimilars: concept, current status, and future perspectives in inflammatory bowel diseases
Sang Hyoung Park, Jae Cheol Park, Milan Lukas, Martin Kolar, Edward V. Loftus, Jr
Intest Res 2020;18(1):34-44.   Published online January 30, 2020

AbstractAbstract PDFPubReaderePub
The inflammatory bowel diseases (IBD), which consist of Crohn’s disease and ulcerative colitis, are chronic, incurable immunemediated inflammatory disorders of the intestine. As IBD incidence continues to increase globally and its mortality is low, prevalent cases of IBD are rapidly increasing, thereby leading to a substantial increase in health care costs. Although the introduction of biologic agents for IBD management has revolutionized the armamentarium of IBD therapy, the high cost of this therapy is concerning. With the expirations of patents for existing biologic agents (originals), biosimilars with cheaper costs have been highlighted in the field of IBD. Despite concerns regarding their short- and long-term efficacy, safety, immunogenicity, and interchangeability, increasing evidence via prospective observations and phase III or IV clinical trials, which aim to prove the “biosimilarity” of biosimilars to originals, has partly confirmed their efficacy, safety, and interchangeability. Additionally, although patients and physicians are reluctant to use biosimilars, a positive budget impact has been reported owing to their use in different countries. In the near future, multiple biosimilars with lower costs, and efficacy and safety profile similar to originals, could be used to treat IBD; thus, further consideration and knowledge dissemination are warranted in this new era of biosimilars.

OPERA is a randomized, multicenter, double-blind, placebo-controlled study to investigate the efficacy, safety, and pharmacokinetics of PF-00547659 following subcutaneous administration in subjects with active CD, a history of failure or intolerance to anti-tumor necrosis factor and/or immunosuppressants, high-sensitivity C-reactive protein > 3.0 mg/L, and ulcers on colonoscopy. The primary endpoint was Crohn’s Disease Activity Index-70 response at week 8 or 12. Subpopulation analyses for Asian subjects were performed as some differences are observed in genetics and clinical phenotypes in Asian CD patients compared with Western patients.
Results
In this study, 265 CD subjects were randomized, with a subpopulation of 21 subjects (8 Japanese and 13 Korean) defined as the Asian population. In the overall and Asian populations; PF-00547659 was pharmacologically active as evidenced by soluble MAdCAM and circulating β7+ central memory CD4+ T-lymphocytes, although no clear evidence of efficacy was observed in any clinical endpoints; pharmacokinetics of PF-00547659 in the Asian subpopulation was generally comparable to the overall population; and the safety profile of PF-00547659 appeared acceptable up to 12 weeks of treatment.
Conclusions
In the overall and Asian populations, efficacy of PF-00547659 could not be demonstrated using any clinical endpoints compared with placebo. Pharmacokinetics and safety of PF-00547659 were generally comparable. Further studies with larger numbers of patients are required to confirm our results. (Trial Registration Number: NCT01276509)

AbstractAbstract PDFPubReaderePub
Background/Aims
Mucosal healing (MH) of distal lesions in ulcerative colitis (UC) has recently been confirmed with budesonide 2-mg foam (BF) treatment in 2 clinical trials; however, few studies have investigated the predictive factors for complete MH.
Methods
We conducted a post hoc analysis using pooled data from phase II and III clinical trials evaluating the efficacy and safety of BF for UC. Additionally, we analyzed the relationships between complete MH and baseline factors and clinical symptoms from baseline to week 6.
Results
Among the 291 Japanese patients from the 2 pooled clinical studies, 119 patients in the BF twice a day group and 117 in the placebo group were included in the full analysis set. The proportion of patients with a rectal bleeding (RB) subscore of 0 was significantly higher in the BF group than in the placebo group after a 5-day treatment (P<0.05). After a 2-day treatment, significantly more patients in the BF group had a stool frequency (SF) subscore of 0 than patients in the placebo group (P<0.05). Multivariate analysis showed that complete MH at week 6 was influenced by baseline SF subscore and 5-aminosalicylic acid (5-ASA) enema or suppository use (P=0.0086 and P=0.0015, respectively). The relationship between complete MH at week 6 and RB subscore after week 2 was also confirmed.
Conclusions
Normal SF at baseline, history of 5-ASA topical product use, and elimination of RB after week 2 are suggested predictors of complete MH at week 6 with twice-daily BF treatment.

AbstractAbstract PDFSupplementary MaterialPubReaderePub
Background/Aims
5-Aminosalicylic acid (ASA) causes intolerance reactions in some patients. This study was performed to examine the prognosis of patients with ulcerative colitis (UC) and 5-ASA intolerance, and to evaluate the potential interaction between 5-ASA intolerance and the intestinal microbiota.
Methods
We performed a retrospective cohort study of patients with UC who visited participating hospitals. The primary endpoint was to compare the incidence of hospitalization within 12 months between the 5-ASA intolerance group and the 5-ASA tolerance group. The secondary endpoint was to compare the risk of adverse clinical outcomes after the start of biologics between the 2 groups. We also assessed the correlation between 5-ASA intolerance and microbial change in an independently recruited cohort of patients with UC.
Results
Of 793 patients, 59 (7.4%) were assigned to the 5-ASA intolerance group and 734 (92.5%) were assigned to the 5-ASA tolerance group. The admission rate and incidence of corticosteroid use were significantly higher in the intolerance than tolerance group (P< 0.001). In 108 patients undergoing treatment with anti-tumor necrosis factor biologics, 5-ASA intolerance increased the incidence of additional induction therapy after starting biologics (P< 0.001). The 5-ASA intolerance group had a greater abundance of bacteria in the genera Faecalibacterium, Streptococcus, and Clostridium than the 5-ASA tolerance group (P< 0.05).
Conclusions
In patients with UC, 5-ASA intolerance is associated with a risk of adverse clinical outcomes and dysbiosis. Bacterial therapeutic optimization of 5-ASA administration may be important for improving the prognosis of patients with UC.

AbstractAbstract PDFPubReaderePub
Background/Aims
Crohn’s disease is associated with altered body composition, such as low muscle mass, which can affect clinical outcomes. However, there are few studies regarding the effect of sarcopenia on prognosis of Crohn’s disease. In this study, we evaluated the body composition at the initial diagnosis of Crohn’s disease and analyzed the clinical meaning of sarcopenia.
Methods
We conducted a retrospective review of medical records of patients who were diagnosed as Crohn’s disease and underwent computed tomography within 3 months after diagnosis. Sarcopenia was defined as an L3 skeletal muscle index (SMI) of < 49 cm2/m2 for men and < 31 cm2/m2 for women. Outcomes such as need for hospitalization, surgery, use of steroids, immunomodulators and biologics were analyzed.
Results
A total of 79 patients (male, 73.4%; mean age, 29.9 years) were included and 40 patients (51%) were diagnosed as sarcopenia. C-reactive protein (CRP) level was correlated with sarcopenia (P= 0.044). Erythrocyte sedimentation rate (ESR) showed a tendency to decrease inversely with SMI (r = –0.320, P= 0.008) and hemoglobin and albumin tended to increase in proportion to SMI (hemoglobin: r = 0.271, P= 0.016 and albumin: r = 0.350, P= 0.002). However, there was no statistically significance in time-to-first-event analysis in aspects of sarcopenia.
Conclusions
Approximately 50% of patients with newly diagnosed as Crohn’s disease had sarcopenia. CRP levels were higher in the sarcopenia group and SMI correlated with ESR, hemoglobin, and albumin. However, none of prognostic values were demonstrated.

Inflammatory bowel diseases
Is fasting beneficial for hospitalized patients with inflammatory bowel diseases?
Yong Eun Park, Yehyun Park, Soo Jung Park, Tae Il Kim, Won Ho Kim, Jung Nam Kim, Na Rae Lee, Jae Hee Cheon
Intest Res 2020;18(1):85-95.   Published online July 19, 2019
DOI: https://doi.org/10.5217/ir.2019.00055
AbstractAbstract PDFSupplementary MaterialPubReaderePub
Background/Aims
Patients with inflammatory bowel disease (IBD) are usually hospitalized because of aggravated gastrointestinal symptoms. Many clinicians empirically advise these patients to fast once they are admitted. However, there has been no evidence that maintaining a complete bowel rest improves the disease course. Therefore, we aimed to investigate the effects of fasting on disease course in admitted patients with IBD or intestinal Behçet’s disease.
Methods
A total of 222 patients with IBD or intestinal Behçet’s disease, who were admitted for disease-related symptoms, were retrospectively analyzed. We divided them into 2 groups: fasting group (allowed to take sips of water but no food at the time of admission) and dietary group (received liquid, soft, or general diet).
Results
On admission, 124 patients (55.9%) started fasting and 98 patients (44.1%) started diet immediately. Among patients hospitalized through the emergency room, a significantly higher proportion underwent fasting (63.7% vs. 21.4%, P<0.001); however, 96.0% of the patients experienced dietary changes. Corticosteroid use (P<0.001; hazard ratio, 2.445; 95% confidence interval, 1.506–3.969) was significantly associated with a reduction in the disease activity score, although there was no significant difference between the fasting group and the dietary group in disease activity reduction (P=0.111) on multivariate analysis.
Conclusions
In terms of disease activity reduction, there was no significant difference between the fasting and dietary groups in admitted patients with IBD, suggesting that imprudent fasting is not helpful in improving the disease course. Therefore, peroral diet should not be avoided unless not tolerated by the patient.

AbstractAbstract PDFPubReaderePub
Background/Aims
We aimed to investigate the proportion of and risk factors for residual cancer and/or lymph node metastasis after surgery was performed because of high-risk pathological features in endoscopic resection specimen of suspected superficial submucosal colorectal cancer (SSMC).
Methods
We reviewed medical records of 497 patients (58.8 ± 9.8 years, 331 males) undergoing endoscopic resection of suspected SSMC. High-risk pathological features included: deep submucosal cancer invasion ≥ 1,000 μm; positive lymphovascular and/or perineural invasion; poorly differentiated adenocarcinoma; and positive resection margin. We investigated the occurrence of additional surgery and residual cancer and/or lymph node involvement in the surgical specimen.
Results
En bloc resection was performed in 447 patients (89.9%). High-risk pathological features were detected in 372 patients (74.8%). Additional surgery was performed in 336 of 372 patients with high-risk pathological features. Of these, 47 surgical specimens (14.0%) showed residual cancer and/or lymph node metastasis. Piecemeal resection was more common in those with residual cancer and/or lymph node involvement than those without (9/47 [19.1%] vs. 24/289 [8.3%], P= 0.032). Positive resection margin was also significantly associated with positive residual cancer and/or lymph node involvement. As the number of high-risk pathological features increased, the risk of regional lymph node metastasis increased proportionally (P= 0.002).
Conclusions
High-risk pathological features were frequently detected after endoscopic resection of suspected SSMC while residual cancer and/or lymph node metastasis were not commonly present in the additional surgical specimen. Further optimized strategy for proper endoscopic management of suspected SSMC is necessary.

AbstractAbstract PDFPubReaderePub
Background/Aims
Magnifying endoscopic classification systems, such as the Japan narrow-band imaging (NBI) Expert Team (JNET) classification, have been widely used for predicting the histologic diagnosis and invasion depth of colorectal epithelial tumors. However, disagreement exists among observers regarding magnifying endoscopic diagnosis, because these classification systems are subjective. We herein investigated the utility of endoscopic microvascular density (eMVD) calculated from magnifying NBI endoscopic images in colorectal tumors.
Methods
We reviewed magnifying NBI endoscopic images from 169 colorectal epithelial tumors (97 adenomas, 72 carcinomas/high-grade dysplasias) resected endoscopically or surgically. The eMVD on magnifying NBI endoscopic images was evaluated using image-editing software, and relationships between eMVD and clinical, endoscopic, and pathological findings were retrospectively analyzed.
Results
The eMVD in carcinomas (0.152 ± 0.079) was significantly higher than that in adenomas (0.119 ± 0.059, P< 0.05). The best cutoff value for distinguishing carcinoma from adenoma was 0.133. Sensitivity, specificity, and accuracy were 56.9%, 67.0%, and 62.7%, respectively. In addition, JNET type 2B tumors showed significantly higher eMVD (0.162 ± 0.079) compared to type 2A tumors (0.111 ± 0.050, P< 0.05).
Conclusions
The eMVD as determined by magnifying NBI endoscopy is considered to be a possible objective indicator for differentiating colorectal carcinomas from adenomas.

AbstractAbstract PDFPubReaderePub
Background/Aims
Irritable bowel syndrome (IBS) is a common disease often considered as a functional intestinal disorder. Inflammation in IBS is a quite intriguing theory. The aim of this study was to investigate tumor necrosis factor (TNF)-α, interleukin (IL)-1β and IL-6 expression in inflammatory bowel disease (IBD) patients, IBS patients and normal controls.
Methods
IBS and IBD patients along with normal controls were recruited in the study. In all groups, 2 pinch biopsies were taken at each of 3 anatomical sites (terminal ileum, cecum, and rectum). IBS patients were also subcategorized according to the syndrome clinical manifestations. Two monoclonal antibodies (mAb), TNF-α mAb and IL-6 mAb, and one polyclonal antibody IL-1β mAb were applied for immunohistochemical analysis.
Results
In IBD patients intensity of TNF-α and IL-1β were lower than in IBS patients or controls, while IL-6 was significantly increased comparing to the aforementioned groups. In IBS patients TNF-α was increased comparing to IBD patients or controls, while IL-6 and IL-1β were similar to controls. In IBS subgroups, TNF-α was lower in diarrhea predominant IBS patients and higher constipation predominant IBS patients. Differences among IBS subgroups regarding IL-6 and IL-1β were nonsignificant.
Conclusions
IL-6 seems to be the most important proinflammatory cytokine in IBD patients, while TNF-α could play a more significant role in IBS pathogenesis.

Background/Aims
Dietary fiber intake is considered a protective factor for diverticular disease such as diverticulitis. However, evidence for an inverse connection between dietary fiber consumption and asymptomatic colonic diverticulosis is lacking. Specifically, few studies have investigated this subject in Asians with different presentations of diverticulosis. Therefore, we assessed the protective effects of a vegetarian diet for asymptomatic colonic diverticulosis in Buddhist monks who are obligatory vegetarians for spiritual reasons compared with the general population.
Methods
A retrospective, cross-sectional, case-control study was conducted in age- and sex-matched Buddhist monks and the general population who underwent colonoscopy for screening at a Korean health promotion center from August 2005 to June 2018. We compared the prevalence of asymptomatic diverticulosis between the 2 groups using a self-administered questionnaire.
Results
In this study, a total of 1,316 individuals were included (Buddhist monks of 658 and general population of 658) with a mean age of 52.6±9.5 years. The prevalence of asymptomatic diverticulosis in Buddhist monks was lower compared with the general population (6.7% [44/658] vs. 10.8% [71/658], P=0.008). Buddhist monks had a higher rate of high body mass index (BMI) and metabolic syndrome. By a multivariate regression analysis model, a nonvegetarian diet (odds ratio [OR], 1.82; 95% confidence interval [CI], 1.21–2.72, P=0.004), old age (OR, 4.53; 95% CI, 1.36–15.12; P=0.014), male sex (OR, 1.91; 95% CI, 1.28–2.85; P=0.002), and a high BMI (OR, 1.50; 95% CI, 1.01–2.23; P=0.047) were independent predictors of asymptomatic diverticulosis. Moreover, a nonvegetarian diet was associated with both right-sided and left-sided diverticulosis.
Conclusions
A nonvegetarian diet may increase a risk of asymptomatic colonic diverticulosis in Asians.

While patients with inflammatory bowel disease are known to be at increased risk of venous thromboembolism, the risk of arterial thrombosis is less well recognized. Here, we describe the case of a middle-aged female with a recent diagnosis of Crohn’s disease who presented to her local emergency department with acute abdominal pain. Subsequent investigations revealed a thrombus in the superior mesenteric artery resulting in multi-organ infarction requiring major intra-abdominal surgery and extensive resection of segments of small and large bowel.
