Abstract PDF PubReader ePub: The lack of clear definition and classification for “moderate ulcerative colitis (UC)” creates ambiguity regarding the suitability of step-up versus top-down treatment approaches. In this paper, experts address crucial gaps in assessing and managing moderate UC. The Asia-Pacific, Middle East, and Africa Inflammatory Bowel Disease Coalition comprised 24 experts who convened to share, discuss and vote electronically on management recommendations for moderate UC. Experts emphasized that the goal of treating UC is to attain clinical, biomarker, and endoscopic remission using cost-effective strategies such as 5-aminosalicylates (5-ASAs), well-tolerated therapy that can be optimized to improve outcomes. Experts agreed that 5-ASA therapy could be optimized by maximizing dosage (4 g/day for induction of remission), combining oral and topical administration, extending treatment duration beyond 8 weeks, and enhancing patient adherence through personalized counselling and reduced pill burden. Treatment escalation should ideally be reserved for patients with predictors of aggressive disease or those who do not respond to 5-ASA optimization. Premature treatment escalation to advanced therapies (including biologics and oral small molecules) may have long-term health and financial consequences. This paper provides consensus-based expert recommendations and a treatment algorithm, based on current evidence and practices, to assist decision-making in real-world settings.

Helminths in alternative therapeutics of inflammatory bowel disease: Himani Pandey, Daryl W. T. Tang, Sunny H. Wong, Devi Lal; Intest Res 2025;23(1):8-22. Published online January 12, 2024; DOI: https://doi.org/10.5217/ir.2023.00059

Abstract PDF PubReader ePub: Inflammatory bowel disease (IBD), which includes Crohn’s disease and ulcerative colitis, is a nonspecific chronic inflammation of the gastrointestinal tract. Despite recent advances in therapeutics and newer management strategies, IBD largely remains untreatable. Helminth therapy is a promising alternative therapeutic for IBD that has gained some attention in the last two decades. Helminths have immunomodulatory effects and can alter the gut microbiota. The immunomodulatory effects include a strong Th2 immune response, T-regulatory cell response, and the production of regulatory cytokines. Although concrete evidence regarding the efficacy of helminth therapy in IBD is lacking, clinical studies and studies done in animal models have shown some promise. Most clinical studies have shown that helminth therapy is safe and easily tolerable. Extensive work has been done on the whipworm Trichuris, but other helminths, including Schistosoma, Trichinella, Heligmosomoides, and Ancylostoma, have also been explored for pre-clinical and animal studies. This review article summarizes the potential of helminth therapy as an alternative therapeutic or an adjuvant to the existing therapeutic procedures for IBD treatment.

Abstract PDF PubReader ePub: Crohn’s disease (CD) is a chronic, fluctuating inflammatory condition that primarily affects the gastrointestinal tract. Although the incidence of CD in Taiwan is lower than that in Western countries, the severity of CD presentation appears to be similar between Asia and the West. This observation indicates the urgency for devising revised guidelines tailored to the unique reimbursement system, and patient requirements in Taiwan. The core objectives of these updated guidelines include the updated treatment choices and the integration of the treat-to-target strategy into CD management, promoting the achievement of deep remission to mitigate complications and enhance the overall quality of life. Given the diversity in disease prevalence, severity, insurance policies, and access to medical treatments in Taiwan, a customized approach is imperative for formulating these guidelines. Such tailored strategies ensure that international standards are not only adapted but also optimized to local contexts. Since the inception of its initial guidelines in 2017, the Taiwan Society of Inflammatory Bowel Disease (TSIBD) has acknowledged the importance of continuous revisions for incorporating new therapeutic options and evolving disease management practices. The latest update leverages international standards and recent research findings focused on practical implementation within the Taiwanese healthcare system.

Abstract PDF PubReader ePub

Ulcerative colitis (UC) is a chronic inflammation of the gastrointestinal tract and is characterized by alternating periods of inflammation and remission. Although UC incidence is lower in Taiwan than in Western countries, its impact remains considerable, demanding updated guidelines for addressing local healthcare challenges and patient needs. The revised guidelines employ international standards and recent research, emphasizing practical implementation within the Taiwanese healthcare system. Since the inception of the guidelines in 2017, the Taiwan Society of Inflammatory Bowel Disease has acknowledged the need for ongoing revisions to incorporate emerging therapeutic options and evolving disease management practices. This updated guideline aims to align UC management with local contexts, ensuring comprehensive and context-specific recommendations, thereby raising the standard of care for UC patients in Taiwan. By adapting and optimizing international protocols for local relevance, these efforts seek to enhance health outcomes for patients with UC.

Cardiovascular disease: extraintestinal manifestation of inflammatory bowel disease: Samridhi Lakhanpal, Kanishk Aggarwal, Harmanjit Kaur, Kunal Kanwar, Vasu Gupta, Jill Bhavsar, Rohit Jain; Intest Res 2025;23(1):23-36. Published online May 7, 2024; DOI: https://doi.org/10.5217/ir.2023.00104

Abstract PDF PubReader ePub: Inflammatory bowel disease (IBD) is a spectrum of diseases characterized by the interplay of the aberrant immune system, genetic factors, environmental factors, and intestinal microbiota, resulting in relapsing inflammation of the gastrointestinal tract. Underlying pro-inflammatory state and immune dysregulation act as a catalyst for increasing the likelihood of developing extraintestinal manifestations, including cardiovascular diseases (CVD) like atherosclerosis, pericarditis, myocarditis, venous and arterial thromboembolism, arrhythmias, despite a lower prevalence of classic CVD risk factors, like high body mass index or dyslipidemia compared to the general population. Chronic inflammation damages endothelium resulting in the recruitment of inflammatory cells, which induce cytotoxicity, lipoprotein oxidation, and matrix degradation, which increases the risk of atherosclerosis. Additionally, intestinal dysbiosis disrupts the intestinal mucosal barrier, releasing endotoxins and lipopolysaccharides into circulation, further exaggerating the atherosclerotic process. Abnormal collagen metabolism and alteration of nitric oxide-mediated vasodilation lead to blood pressure dysregulation in patients with IBD. Therefore, it is essential to make lifestyle modifications like smoking cessation, dietary changes, and increasing physical activity with adherence to medication to mitigate the risk of developing CVD in patients with IBD. This article reviews the potential links between IBD and the increased risk of CVD in such individuals.

Filgotinib induction-study baseline characteristics of patients with ulcerative colitis who achieve sustained corticosteroid-free remission: post hoc analysis of the phase 2b/3 SELECTION study: Taku Kobayashi, Axel Dignass, Xavier Roblin, Yoshie Takatori, Toshihiko Kaise, Alessandra Oortwijn, Corinne Jamoul, Toshifumi Hibi; Intest Res 2025;23(1):65-75. Published online June 14, 2024; DOI: https://doi.org/10.5217/ir.2024.00007

Abstract PDF Supplementary Material PubReader ePub

Background/Aims
Obtaining and maintaining corticosteroid-free remission are important goals of treatment for ulcerative colitis (UC). Characteristics associated with achieving corticosteroid-free remission were assessed in filgotinib-treated patients in SELECTION, a 58-week, phase 2b/3 trial in moderately to severely active UC.
Methods
This post hoc analysis used data from filgotinib-treated patients receiving corticosteroids at maintenance baseline in SELECTION. Univariate logistic regression was performed to assess induction baseline characteristics associated with 6 months of corticosteroid-free remission at week 58, defined as clinical remission without using corticosteroids for at least 6 months.
Results
At maintenance baseline, 92 and 81 patients were receiving corticosteroids in the filgotinib 200 mg and filgotinib 100 mg groups, respectively. Age, body mass index, history of pancolitis, disease duration, fecal calprotectin levels, C-reactive protein levels, Mayo Clinic Score, concomitant corticosteroids, immunomodulators, and aminosalicylates had no statistically significant effect on the likelihood of achieving corticosteroid-free remission. Baseline characteristics associated with increased odds of corticosteroid-free remission were Mayo Clinic Endoscopic Subscore of 2 (vs. 3) in the filgotinib 200 mg and filgotinib 100 mg groups, and female (vs. male) sex, current (vs. former or never) smoking, and being biologic‑naive (vs. experienced) in the filgotinib 200 mg group.
Conclusions
Steroid tapering can be achieved in patients with UC receiving filgotinib 200 mg independently of baseline characteristics such as clinical activity and duration of illness. However, the likelihood of achieving corticosteroid-free remission was higher among patients who were biologic-naive, current smokers, had low endoscopic inflammatory burden and who were female.

Animal models of inflammatory bowel disease: novel experiments for revealing pathogenesis of colitis, fibrosis, and colitis-associated colon cancer: Chan Hyung Lee, Seong-Joon Koh, Zaher A Radi, Aida Habtezion; Intest Res 2023;21(3):295-305. Published online May 31, 2023; DOI: https://doi.org/10.5217/ir.2023.00029

Abstract PDF PubReader ePub

Inflammatory bowel disease (IBD), comprising Crohn’s disease and ulcerative colitis, is a lifelong disease that manifests with chronic intestinal inflammation, sequential fibrosis, and an increased risk of colitis-associated colon cancer (CAC). The combined effects of genetic, immunological, environmental, and microbial factors render it difficult to determine the specific mechanism underlying the induction and perpetuation of IBD. Various animal models of IBD have contributed enormously to the understanding of IBD pathogenesis in terms of genomics, transcriptomics, proteomics, microbiome, and drug development of novel therapeutics. Although comprehensive research on IBD has been enabled by advanced technologies, such as genetically engineered models, there is a great need to develop relevant in vivo models of colitis and fibrosis. Here, we review 4 categories of animal models of acute and chronic intestinal inflammation, fibrosis, and CAC: chemically induced, genetically engineered, T cell transfer, and spontaneous gene mutation models.

Association between nonalcoholic fatty liver disease and incidence of inflammatory bowel disease: a nationwide population‑based cohort study: Ying-Hsiang Wang, Chi-Hsiang Chung, Tien-Yu Huang, Chao-Feng Chang, Chi-Wei Yang, Wu-Chien Chien, Yi-Chiao Cheng; Intest Res 2025;23(1):76-84. Published online February 21, 2024; DOI: https://doi.org/10.5217/ir.2023.00078

Abstract PDF Supplementary Material PubReader ePub

Background/Aims
Nonalcoholic fatty liver disease (NAFLD) is a common disease with severe inflammatory processes associated with numerous gastrointestinal diseases, such as inflammatory bowel disease (IBD). Therefore, we investigated the relationship between NAFLD and IBD and the possible risk factors associated with the diagnosis of IBD.
Methods
This longitudinal nationwide cohort study investigated the risk of IBD in patients with NAFLD alone. General characteristics, comorbidities, and incidence of IBD were also compared.
Results
Patients diagnosed with NAFLD had a significant risk of developing IBD compared to control individuals, who were associated with a 2.245-fold risk of the diagnosis of IBD and a 2.260- and 2.231-fold of increased diagnosis of ulcerative colitis and Crohn’s disease, respectively (P< 0.001). The cumulative risk of IBD increased annually during the follow-up of patients with NAFLD (P< 0.001).
Conclusions
Our results emphasize that NAFLD significantly impacts its incidence in patients with NAFLD. If patients with NAFLD present with risk factors, such as diabetes mellitus and dyslipidemia, these conditions should be properly treated with regular follow-ups. Furthermore, we believe that these causes may be associated with the second peak of IBD.

Published online August 29, 2024; DOI: https://doi.org/10.5217/ir.2024.00013

Abstract PDF PubReader ePub: A 47-year-old man with over 10 years’ duration of ulcerative colitis treated by 5-aminosalicylic acid and intermittent topical steroids complained of acute epigastric pain. Esophagogastroduodenoscopy revealed diffuse mucosal edema with patchy redness, multiple erosions and nodularity of the stomach. Bioptic examination revealed marked eosinophilic infiltration, confirming the diagnosis of eosinophilic gastroenteritis. Systemic steroid therapy was initiated, whereas his ulcerative colitis and eosinophilia recurred when tapering the steroid. Addition of azathioprine was ineffective, and we subsequently started vedolizumab for eosinophilic gastroenteritis and ulcerative colitis. The medication effectively improved his abdominal symptoms and esophagogastroduodenoscopy and ileocolonoscopy 1 year later revealed endoscopic improvement of both diseases with histologically decreased level of eosinophilic infiltration. Considering that eosinophils also express α4β7 integrins, vedolizumab can be a possible therapeutic candidate for eosinophilic gastroenteritis as well as ulcerative colitis.

What to do when traditional rescue therapies fail in acute severe ulcerative colitis: Christopher F. D. Li Wai Suen, Matthew C. Choy, Peter De Cruz; Intest Res 2024;22(4):397-413. Published online May 16, 2024; DOI: https://doi.org/10.5217/ir.2024.00003

Abstract PDF PubReader ePub

Acute severe ulcerative colitis (ASUC) is a medical emergency that affects approximately 25% of patients with ulcerative colitis at some point in time in their lives. Outcomes of ASUC are highly variable. Approximately 30% of patients do not respond to corticosteroids and up to 50% of patients do not respond to rescue therapy (infliximab or cyclosporin) and require emergency colectomy. Data are emerging on infliximab dosing strategies, use of cyclosporin as a bridge to slower acting biologic agents and Janus kinase inhibition as primary and sequential therapy. In this review, we outline contemporary approaches to clinical management of ASUC in the setting of failure to respond to traditional rescue therapies.

Abstract PDF Supplementary Material PubReader ePub: Background/Aims
Patients with diverticular disease (DD) frequently have abnormal bowel movements. However, it is unknown whether the entity of these alterations is associated with the severity of DD. We aimed to assess bowel habits and their relationship with the severity of DD according to Diverticular Inflammation and Complication Assessment (DICA) classification, Combined Overview on Diverticular Assessment (CODA) score, and fecal calprotectin (FC).
Methods
An international, multicenter, prospective cohort study was conducted in 43 centers. A 10-point visual analog scale (VAS) was used to assess the severity of constipation and diarrhea. The association of constipation and diarrhea with DICA classification, CODA score, and basal FC was tested using non-parametric tests. Survival methods for censored observations were applied to test the association of constipation and diarrhea with the incidence of acute diverticulitis over a 3-year follow-up.
Results
Of 871 patients with DD were included in the study. Of these, 208 (23.9%) and 199 (22.9%) reported a VAS score for constipation and diarrhea at least 3 at baseline, respectively. Higher constipation and diarrhea scores were associated with increasing DICA classification, CODA score and basal FC (P< 0.001). Constipation and diarrhea scores were independently associated with an increased hazard of developing acute diverticulitis (hazard ratio [HR]_constipation = 1.15 per 1-VAS point increase, 95% confidence interval [CI], 1.04–1.27; P=0.004; and HR_diarrhea =1.14; 95% CI, 1.03–1.26; P=0.014, respectively).
Conclusions
In newly diagnosed patients with DD, higher endoscopic and combined scores of DD severity were associated with higher scores of constipation and diarrhea at baseline. Both constipation and diarrhea were independent prognostic factors of acute diverticulitis.

Background/Aims
One complication of restorative proctocolectomy with ileo-anal pouch anastomosis is fistula formation in the pouch. Fistulas can be associated with significant morbidity and pouch failure. We conducted a systematic review with meta- analysis to try and understand the prevalence of pouch fistulas in patients with ulcerative colitis following restorative proctocolectomy.
Methods
The Embase, Embase Classic, and PubMed databases were searched between January 1979 and April 2022. Studies were included if there were cross-sectional, case-controlled, population-based or cohort studies reporting on prevalence of pouch fistulas in ulcerative colitis. Studies had to report the number of patients with pouch fistulas using either clinical, endoscopic, or radiological diagnosis in an adult population.
Results
Thirty-three studies screened met the inclusion criteria. The pooled prevalence of developing at least 1 fistula was 0.05 (95% confidence interval [CI], 0.04–0.07). The pooled prevalence of pouch failure in patients with pouch fistula was found to be 0.24 (95% CI, 0.19–0.30). The pooled prevalence of developing a pouch fistula at 3 years, 5 years and more than 5 years was 0.04 (95% CI, 0.02–0.07), 0.05 (95% CI, 0.02–0.07), and 0.05 (95% CI, 0.02–0.10), respectively.
Conclusions
This is the first systematic review and meta-analysis to report the prevalence of pouch fistula. It also provides a pooled prevalence of pouch failure in these patients. These results can help to shape future guidelines, power future studies, and help counsel patients.

The evolving understanding of histology as an endpoint in ulcerative colitis: Shintaro Akiyama, Yusuke Miyatani, David T. Rubin; Intest Res 2024;22(4):389-396. Published online March 13, 2024; DOI: https://doi.org/10.5217/ir.2023.00120

Abstract PDF PubReader ePub

A therapeutic goal for patients with ulcerative colitis (UC) is deep remission including clinical remission and mucosal healing. Mucosal healing was previously defined by endoscopic appearance, but recent studies demonstrate that histological improvements can minimize the risks of experiencing clinical relapse after achieving endoscopic remission, and there is growing interest in the value and feasibility of histological targets of treatment in inflammatory bowel disease, and specifically UC. In this review article, we identify remaining challenges and discuss an evolving role of histology in the management of UC.

Efficacy and safety of mirikizumab as induction and maintenance therapy for Japanese patients with moderately to severely active ulcerative colitis: a subgroup analysis of the global phase 3 LUCENT-1 and LUCENT-2 studies: Taku Kobayashi, Katsuyoshi Matsuoka, Mamoru Watanabe, Tadakazu Hisamatsu, Fumihito Hirai, Joe Milata, Xingyuan Li, Nathan Morris, Vipin Arora, Tomoko Ishizuka, Koji Matsuo, Yoichi Satoi, Catherine Milch, Toshifumi Hibi; Intest Res 2024;22(2):172-185. Published online April 25, 2024; DOI: https://doi.org/10.5217/ir.2023.00043

Abstract PDF Supplementary Material PubReader ePub

Background/Aims
Mirikizumab is a p19-directed anti-interleukin-23 antibody with potential efficacy against ulcerative colitis (UC). We evaluated the efficacy and safety of mirikizumab in a Japanese subpopulation with moderately to severely active UC from the LUCENT-1 and LUCENT-2 studies.
Methods
LUCENT-1 and LUCENT-2 were phase 3, randomized, double-blind, placebo-controlled trials of mirikizumab therapy in adults with moderately to severely active UC. LUCENT-1 was a 12-week induction trial where patients were randomized 3:1 to receive intravenous mirikizumab 300 mg or placebo every 4 weeks (Q4W). Patients achieving a clinical response with mirikizumab following the induction study were re-randomized 2:1 to double-blind treatment with either mirikizumab 200 mg or placebo subcutaneously Q4W during the 40-week maintenance study. The primary outcomes were clinical remission at week 12 of LUCENT-1 and week 40 of LUCENT-2.
Results
A total of 137 patients enrolled in Japan were randomized to mirikizumab (n = 102) or placebo (n = 35). Compared with placebo, patients who received mirikizumab showed numerically higher clinical remission at week 12 of induction (32.4% [n = 33] vs. 2.9% [n = 1]) and at week 40 of maintenance (48.9% [n = 23] vs. 28.0% [n = 7]). A greater number of patients achieved key secondary endpoints in the mirikizumab group compared with placebo. The frequency of treatment-emergent adverse events was similar across mirikizumab and placebo groups. Efficacy and safety results observed in the Japanese subpopulation were generally consistent with those in the overall population.
Conclusions
Mirikizumab induction and maintenance treatments were effective in Japanese patients with moderately to severely active UC. No new safety concerns were identified.

Abstract PDF PubReader ePub: Irritable bowel syndrome (IBS) is a highly prevalent gastrointestinal disorder associated with substantial impairment which considerably burdens healthcare systems worldwide. Research on IBS has largely been conducted in high-income countries posing barriers to the application of diagnostic strategies in low- and middle-income countries (LMICs) due to differences in disease characteristics, healthcare resources, and socioeconomic factors. This review discusses the diagnostic issues associated with LMICs. We present a concise overview of the relevant approaches and propose a diagnostic strategy based on the latest evidence. A positive diagnostic strategy that relies on appropriate symptom-based criteria is crucial within the diagnostic framework. A combination of complete blood count, fecal occult blood test, and complete stool test may reliably identify individuals with suspected IBS who are more likely to have organic diseases, thus justifying the necessity for a colonoscopy. Eventually, we developed a diagnostic algorithm based on a limited setting perspective that summarizes the available evidence and may be applied in LMICs.

Gut microbiota in pathophysiology, diagnosis, and therapeutics of inflammatory bowel disease: Himani Pandey, Dheeraj Jain, Daryl W. T. Tang, Sunny H. Wong, Devi Lal; Intest Res 2024;22(1):15-43. Published online November 8, 2023; DOI: https://doi.org/10.5217/ir.2023.00080

Abstract PDF PubReader ePub

Inflammatory bowel disease (IBD) is a multifactorial disease, which is thought to be an interplay between genetic, environment, microbiota, and immune-mediated factors. Dysbiosis in the gut microbial composition, caused by antibiotics and diet, is closely related to the initiation and progression of IBD. Differences in gut microbiota composition between IBD patients and healthy individuals have been found, with reduced biodiversity of commensal microbes and colonization of opportunistic microbes in IBD patients. Gut microbiota can, therefore, potentially be used for diagnosing and prognosticating IBD, and predicting its treatment response. Currently, there are no curative therapies for IBD. Microbiota-based interventions, including probiotics, prebiotics, synbiotics, and fecal microbiota transplantation, have been recognized as promising therapeutic strategies. Clinical studies and studies done in animal models have provided sufficient evidence that microbiota-based interventions may improve inflammation, the remission rate, and microscopic aspects of IBD. Further studies are required to better understand the mechanisms of action of such interventions. This will help in enhancing their effectiveness and developing personalized therapies. The present review summarizes the relationship between gut microbiota and IBD immunopathogenesis. It also discusses the use of gut microbiota as a noninvasive biomarker and potential therapeutic option.

The impact of the COVID-19 pandemic on clinical practices related to colorectal cancer and colonoscopy in South Korea: a nationwide population-based study: Jin Young Yoon, Moon Hyung Lee, Min Seob Kwak, Jae Myung Cha; Intest Res 2025;23(1):85-95. Published online November 29, 2024; DOI: https://doi.org/10.5217/ir.2024.00066

Abstract PDF Supplementary Material PubReader ePub

Background/Aims
Despite of the coronavirus disease 2019 (COVID-19) pandemic, there is little data regarding its impact on colorectal cancer (CRC)-related clinical practice. This study aimed to assess the changes in its impact during the COVID-19 pandemic.
Methods
This was a retrospective national population-based study using the Health Insurance Review and Assessment database from January 2019 to December 2021. The number of patients in 2020 and 2021 was compared with those in 2019 for the diagnostic and therapeutic colonoscopy, CRC-related operation, and any treatment for CRC.
Results
The annual number of patients undergoing diagnostic colonoscopies decreased by 6.9% in 2020 but increased 8.1% in 2021, compared to those in 2019; number of patients undergoing therapeutic colonoscopies increased by 6.0% and 37.7% in 2020 and 2021, respectively; number of patients operated for CRC decreased by 4.2% in 2020 and increased by 2.3% in 2021. The number of patients treated for CRC decreased by 2.8% in 2020 and increased by 4.4% in 2021. Diagnostic and therapeutic colonoscopies and any CRC-related treatment decreased by 43.8%, 37.5%, and 11.3% in March 2020, during the first surge of COVID-19, but increased by 26.0%, 58.1%, and 9.5% in June 2021, respectively. CRC-related operations decreased by 24.1% in April 2020 and increased by 12.6% in August 2021.
Conclusions
Negative impact of the COVID-19 pandemic on clinical practices related to CRC completely recovered within second year. It could be considered for the development of an optimal strategy on CRC management in response to the pandemic-driven crisis.

Abstract PDF Supplementary Material PubReader ePub

Ulcerative colitis (UC), a relapsing-remitting chronic inflammatory bowel disease (IBD), has a variable natural course but potentially severe disease course. Since the development of anti-tumor necrosis factor (TNF) agents has changed the natural disease course of moderate-to-severe UC, therapeutic options for patients who failed conventional treatments are expanding rapidly. IBD clinical trials have demonstrated the potential efficacy and safety of novel biologics such as anti-integrin α4β7 and anti-interleukin-12/23 monoclonal antibodies and small molecules such as a Janus kinase inhibitor. Anti-TNF biosimilars also have been approved and are widely used in IBD patients. Wise drug choices should be made considering evidence-based efficacy and safety. However, the best position of these drugs remains several questions, with limited data from direct comparative trials. In addition, there are still concerns to be elucidated on the effect of therapeutic drug monitoring and combination therapy with immunomodulators. The appropriate treatment regimens in acute severe UC and the risk of perioperative use of biologics are unclear. As novel biologics and small molecules have been approved in Korea, we present the Korean guidelines for medical management of adult outpatients with moderate-to-severe UC and adult hospitalized patients with acute severe UC, focusing on biologics and small molecules.

Artificial intelligence in inflammatory bowel disease: implications for clinical practice and future directions: Harris A. Ahmad, James E. East, Remo Panaccione, Simon Travis, James B. Canavan, Keith Usiskin, Michael F. Byrne; Intest Res 2023;21(3):283-294. Published online April 20, 2023; DOI: https://doi.org/10.5217/ir.2023.00020

Abstract PDF PubReader ePub

Inflammatory bowel disease encompasses Crohn’s disease and ulcerative colitis and is characterized by uncontrolled, relapsing, and remitting course of inflammation in the gastrointestinal tract. Artificial intelligence represents a new era within the field of gastroenterology, and the amount of research surrounding artificial intelligence in patients with inflammatory bowel disease is on the rise. As clinical trial outcomes and treatment targets evolve in inflammatory bowel disease, artificial intelligence may prove as a valuable tool for providing accurate, consistent, and reproducible evaluations of endoscopic appearance and histologic activity, thereby optimizing the diagnosis process and identifying disease severity. Furthermore, as the applications of artificial intelligence for inflammatory bowel disease continue to expand, they may present an ideal opportunity for improving disease management by predicting treatment response to biologic therapies and for refining the standard of care by setting the basis for future treatment personalization and cost reduction. The purpose of this review is to provide an overview of the unmet needs in the management of inflammatory bowel disease in clinical practice and how artificial intelligence tools can address these gaps to transform patient care.

First aid with color atlas for the use of intestinal ultrasound for inflammatory bowel disease in daily clinical practice: Jun Miyoshi, Hiromu Morikubo, Hiromi Yonezawa, Hideaki Mori, Tadakazu Hisamatsu; Intest Res 2023;21(2):177-188. Published online April 28, 2023; DOI: https://doi.org/10.5217/ir.2023.00003

Abstract PDF PubReader ePub

Intestinal ultrasound (IUS) is a promising modality for the management of inflammatory bowel disease (IBD) and has the potential to particularly contribute in monitoring disease activity, an advantage crucial for optimizing the therapeutic strategy. While many IBD physicians appreciate and are interested in the use of IUS for IBD, currently only a limited number of facilities can employ this examination in daily clinical practice. A lack of guidance is one of the major barriers to introducing this procedure. Standardized protocols and assessment criteria are needed such that IUS for IBD can be considered a feasible, reliable examination in clinical practice, and multicenter clinical studies can be conducted for further clinical evidence of the application of IUS in IBD for best patient care. In this article, we provide an overview of how to start IUS for IBD and introduce basic procedures. Furthermore, IUS images from our practice are provided as a color atlas for understanding sonographic findings and scoring systems. We anticipate this “first aid” article will be helpful to promote IUS for IBD in daily practice.

Long-term efficacy and safety of tofacitinib in patients with ulcerative colitis: 3-year results from a real-world study: Hiromichi Shimizu, Yuko Aonuma, Shuji Hibiya, Ami Kawamoto, Kento Takenaka, Toshimitsu Fujii, Eiko Saito, Masakazu Nagahori, Kazuo Ohtsuka, Ryuichi Okamoto; Intest Res 2024;22(3):369-377. Published online July 16, 2024; DOI: https://doi.org/10.5217/ir.2023.00194

Abstract PDF Supplementary Material PubReader ePub

Background/Aims
The efficacy and safety of tofacitinib for the treatment of refractory ulcerative colitis (UC) has been demonstrated in clinical trials. Although, a series of reports with real-world evidence of its short-term efficacy and safety profiles have already been published, reports of long-term real-world data have been limited. We aimed to show our 3-year evidence on the clinical use of tofacitinib for the treatment of UC, focusing on its efficacy and safety profiles.
Methods
A retrospective observational study was conducted on patients who started tofacitinib for active refractory UC at our hospital. The primary outcome was the retention rate until 156 weeks after initiating tofacitinib. The secondary outcomes were short-term efficacy at 4, 8, and 12 weeks; long-term efficacy at 52, 104, and 156 weeks; prognostic factors related to the cumulative retention rate; loss of response; and safety profile, including adverse events.
Results
Forty-six patients who were able to be monitored for up to 156 weeks after tofacitinib initiation, were enrolled in this study. Continuation of tofacitinib was possible until 156 weeks in 54.3%, with > 50% response rates and > 40% remission rates. Among patients in whom response or remission was achieved and tofacitinib was deescalated after 8 weeks of induction treatment, 54.3% experienced relapse but were successfully rescued by and retained on reinduction treatment, except for 1 patient. No serious AEs were observed in the study.
Conclusions
Tofacitinib is effective and safe as long-term treatment in a refractory cohort of UC patients in real-world clinical practice.

Colorectal neoplasia

Summary and comparison of recently updated post-polypectomy surveillance guidelines: Yoon Suk Jung; Intest Res 2023;21(4):443-451. Published online October 26, 2023; DOI: https://doi.org/10.5217/ir.2023.00107

Abstract PDF PubReader ePub

Recently, updated guidelines for post-polypectomy surveillance have been published by the U.S. Multi‐Society Task Force (USMSTF), the British Society of Gastroenterology/Association of Coloproctology of Great Britain and Ireland/Public Health England (BSG/ACPGBI/PHE), the European Society of Gastrointestinal Endoscopy (ESGE), the Japan Gastroenterological Endoscopy Society (JGES), and the Korean Multi-Society Taskforce Committee. This review summarizes and compares the updated recommendations of these 5 guidelines. There are some differences between the guidelines for the recommended post-polypectomy surveillance intervals. In particular, there are prominent differences between the guidelines for 1–4 tubular adenomas < 10 mm with low-grade dysplasia (nonadvanced adenomas [NAAs]) and tubulovillous or villous adenomas. The USMSTF, JGES, and Korean guidelines recommend colonoscopic surveillance for patients with 1–4 NAAs and those with tubulovillous or villous adenomas, whereas the BSG/ACPGBI/PHE and ESGE guidelines do not recommend endoscopic surveillance for such patients. Surveillance recommendations for patients with serrated polyps (SPs) are limited. Although the USMSTF guidelines provide specific recommendations for patients who have undergone SPs removal, these are weak and based on very lowquality evidence. Future studies should examine this topic to better guide the surveillance recommendations for patients with SPs. For countries that do not have separate guidelines, we hope that this review article will help select the most appropriate guidelines as per each country’s healthcare environment.

Background/Aims
As the characteristics of inflammatory bowel disease (IBD) differ between Asians and Westerners, it is necessary to determine adequate therapeutic strategy for Asian IBD patients. We evaluated the current treatment of IBD in Asian countries/regions using a web-based survey.
Methods
The Korean Association for the Study of Intestinal Diseases conducted a multinational web-based survey for current IBD care in Asia between September 16, 2020, and November 13, 2020.
Results
A total of 384 doctors treating IBD patients from 24 Asian countries/regions responded to the survey. Anti-tumor necrosis factor (TNF) agents, anti-integrins, and anti-interleukin-12/23 agents were available for use by 93.8%, 72.1%, and 70.1% of respondents in Asian countries/regions. Compared with a previous survey performed in 2014, an increased tendency for treatment with biologics, including anti-TNF agents, was observed. In the treatment of corticosteroid-refractory acute severe ulcerative colitis, 72.1% of respondents chose anti-TNF agents, followed by tacrolimus (11.7%). In the treatment of corticosteroid-refractory Crohn’s disease, 90.4% chose anti-TNF agents, followed by thiopurines (53.1%), anti-interleukin-12/23 agents (39.3%), and anti-integrin agents (35.7%). In the treatment of Crohn’s disease patients refractory to anti-TNF agents, the most preferred strategy was to measure serum levels of anti-TNF and anti-drug antibodies (40.9%), followed by empiric dose escalation or shortening of dosing intervals (25.3%).
Conclusions
Although there were some differences, treatment strategies for patients with IBD were mostly similar among Asian doctors. Based on the therapeutic outcomes, it is necessary to identify the most appropriate therapeutic strategy for Asian IBD patients.

Abstract PDF PubReader ePub

Crohn’s disease (CD) is a relapsing and progressive condition characterized by diarrhea, abdominal pain, weight loss, and hematochezia that results in serious complications such as perforations, fistulas, and abscesses. Various medications, interventions, and surgical treatments have been used to treat CD. The Korean guidelines for CD management were distributed in 2012 and revised in 2017 by the Inflammatory Bowel Disease (IBD) Research Group of the Korean Association for the Study of Intestinal Diseases. Substantial progress in mucosal immunologic research has elucidated the pathophysiology of IBD, leading to development of biological agents for treatment of CD. The first developed biologic agent, tumor necrosis factor-α agents, were shown to be efficacious in CD, heralding a new era in management of CD. Subsequently, vedolizumab, a monoclonal antibody against integrin α4β7, and ustekinumab, a human monoclonal antibody that inhibits the common p40 subunit of interleukin-12 and interleukin-23, were both approved for clinical use and are efficacious and safe for both induction and maintenance of remission in moderate-to-severe CD patients. Moreover, a recent study showed the non-inferiority of CT-P13, an infliximab biosimilar, compared with infliximab in CD patients. The third Korean guidelines for CD management provide updated information regarding treatment of moderate-to-severe CD patients with biologic agents.

Functional bowel disorder

An Asian perspective on irritable bowel syndrome: Kee Wook Jung, Seung-Jae Myung; Intest Res 2023;21(2):189-195. Published online May 31, 2022; DOI: https://doi.org/10.5217/ir.2021.00136

Abstract PDF PubReader ePub

Irritable bowel syndrome (IBS) is a prevalent chronic disorder, and its epidemiology depends on the diagnostic criteria used. Recently, the Rome IV criteria for IBS were published by changing the frequency of abdominal pain and excluding abdominal discomfort from the previously used Rome III criteria. However, the recent Asian consensus on IBS recommends the inclusion of abdominal discomfort and abdominal pain as diagnostic criteria. The low fermentable oligo-, di-, mono-saccharides, and polyols (FODMAP) diet has been proven to be effective in Western patients. Moreover, recent well-designed studies reported its effectiveness and the microbial changes after implementing it in Asian patients with IBS. However, traditional Korean foods including kimchi, one of representative FODMAP-rich food, exhibited a poor correlation with the food-related symptoms of IBS. Therefore, the low FODMAP diet protocol should be cautiously applied to IBS patients, especially to Korean patients with IBS. In Asian countries, there are lots of traditional herbal medicines and treatments for IBS; however, these studies have limitations including the heterogeneity of herbal mixtures and relatively small sample size. Therefore, well-designed studies based on large samples are required to validate complementary and alternative medicine in the treatment of Asian patients with IBS.

IBD

The practice of fecal microbiota transplantation in inflammatory bowel disease: Umang Arora, Saurabh Kedia, Vineet Ahuja; Intest Res 2024;22(1):44-64. Published online November 21, 2023; DOI: https://doi.org/10.5217/ir.2023.00085

Abstract PDF PubReader ePub

Current evidence posits a central role for gut microbiota and the metabolome in the pathogenesis and progression of inflammatory bowel disease (IBD). Fecal microbiota transplantation (FMT) has been established as a means to manipulate this microbiome safely and sustainably. Several aspects of the technical improvement including pretreatment with antibiotics, use of frozen stool samples as well as short donor-to-recipient time are proposed to improve its response rates. Its efficacy in ulcerative colitis has been proven in clinical trials while data is emerging for Crohn’s disease. This review describes briefly the biology behind FMT, the available evidence for its use in IBD, and the host, recipient and procedural factors which determine the clinical outcomes.

Early change in serum leucine-rich α-2-glycoprotein predicts clinical and endoscopic response in ulcerative colitis: Ryo Karashima, Shintaro Sagami, Yoko Yamana, Masa Maeda, Aya Hojo, Yusuke Miyatani, Masaru Nakano, Takahisa Matsuda, Toshifumi Hibi, Taku Kobayashi; Intest Res 2024;22(4):473-483.

Abstract PDF PubReader ePub

Background/Aims
Leucine-rich α-2-glycoprotein (LRG) is a new serum biomarker reflecting the disease activity of ulcerative colitis (UC), but its change during the acute phase has not been enough investigated.
Methods
Patients with UC who initiated the induction therapy with steroid or advanced therapy (biologics or Janus kinase inhibitors) were prospectively enrolled. Associations of LRG, C-reactive protein (CRP) and fecal calprotectin (FC) at baseline, week 1, and week 8 with clinical remission at week 8 and subsequent endoscopic improvement within 1 year (Mayo endoscopic subscore of 0 or 1) were assessed.
Results
A total of 143 patients with UC were included. LRG and CRP at week 1 were significantly lower in the clinical remission group than in the non-remission group (LRG, 20.6 μg/mL vs. 28.4 μg/mL, P< 0.001; CRP, 0.9 mg/dL vs. 2.3 mg/dL, P< 0.001) while FC demonstrated the difference between groups only at week 8. The area under the curves of week 1 LRG, CRP, and FC for week 8 clinical remission using the receiver operating characteristic curves analysis were 0.68, 0.71, and 0.57, respectively. Furthermore, LRG and CRP predicted subsequent endoscopic improvement as early as week 1, while FC was predictive only at week 8.
Conclusions
LRG can be an early-phase biomarker predicting subsequent clinical and endoscopic response to induction therapy.
