Abstract
Solid evidence has emerged supporting the role of nonextractable polyphenols (NEPs) and dietary fibers (DFs) as gut microbiota modulators. This study aims to elucidate gut microbiota-dependent release of turmeric NEPs and examine the possible anti-inflammatory mechanism in the dextran sulfate sodium-induced ulcerative colitis (UC) model. 1.5% DSS drinking water-induced C57BL/6J mice were fed a standard rodent chow supplemented with or without 8% extractable polyphenols (EPs), NEPs, or DFs for 37 days. The bound curcumin, demethoxycurcumin, and bisdemethoxycurcumin in NEPs were released up to 181.5 ± 10.6, 65.2 ± 6.0, and 69.5 ± 7.6 μg/mL by in vitro gut microbiota-simulated fermentation and released into the colon of NEP-supplemented mice by 5.7-, 11.0-, and 7.8-fold higher than pseudo germ-free mice, respectively (p < 0.05). NEPs also enhanced the colonic microbiota-dependent production of short-chain fatty acids in vitro and in vivo (p < 0.05). Interestingly, NEP feeding significantly improved the DSS-caused gut microbiota disorder, epithelial barrier damage, and inflammation of UC mice better than EPs or DFs (p < 0.05). Meanwhile, the pseudo germ-free mice supplemented with NEPs failed to ameliorate UC symptoms. These findings manifest that turmeric NEPs as macromolecular carriers exert the target delivery of polyphenols into the colon for regulating gut microbiota to restore the impaired gut barrier function for alleviation of inflammation.

Abstract
Enterotoxigenic Escherichia coli (ETEC) can damage intestinal epithelial barrier function and lead to serious intestinal diarrhea in newborns and young animals. Sodium humate (HNa) is natural organic bioactive compound possessing antibacterial, anti-inflammatory, and anti-diarrheal properties. This study investigated the alleviative potential of HNa on the impaired intestinal barrier and intestinal inflammation, and regulatory effects on gut microbiota and metabolites in ETEC K88 infected mice. A total of 30 female mice were randomly assigned into three groups. The mice in the control and ETEC groups were gavaged with 0.2 mL of sterile saline, while the mice in the ETEC + HNa group were gavaged with 0.2 mL of 5% HNa, daily. On day 8, the mice in ETEC and ETEC + HNa group were challenged with ETEC K88. The trial lasted for 12 days. HNa administration elevated ETEC K88-induced body weight loss and ameliorated jejunum and colon pathological injury. HNa also reduced the levels of pro-inflammatory cytokines in the serum, jejunum, and colon. Additionally, HNa reduced intestinal barrier damage by up-regulating the expression of tight junction proteins (TJPs) and mucosal repair factors. 16s rDNA gene sequencing results showed that HNa increased the abundance of beneficial bacteria Lactobacillus, Prevotella_9, and Odoribacter but decreased the abundance of pathogenic bacteria Escherichia and Gastranaerophilales in the feces of mice. Moreover, metabolomic analysis revealed that the concentrations of 15 metabolites, the pathways of protein digestion and absorption, and propanoic acid metabolism were changed by HNa administration. In conclusion, HNa could alleviate ETEC K88-induced intestinal dysfunction through restoring intestinal barrier integrity, modulating gut microbiota, and metabolites.

Abstract
Compared with the available drugs for the treatment of fibrosis in other organs, the development of intestinal anti-fibrosis drugs is limited. Therefore, it is of practical significance to examine novel drugs to delay or block the development of intestinal fibrosis. The present study aimed to investigate the effect of atractylenolide III (ATL-III) on intestinal fibrosis. An MTT assay was used to detect the effect of ATL-III on the activity of IEC-6 cells. The migration and invasion of fibrotic cells stimulated with TGF-β were determined via wound healing and Transwell assays. An immunofluorescence assay and western blotting were conducted to assess the expression levels of protein associated with epithelial-mesenchymal transition (EMT). The role of the AMP-activated protein kinase (AMPK) pathway was verified using compound C (an AMPK inhibitor) treatment. The results of the present study indicated that ATL-III had no effect on the cells at a dose of 1–20 µmol/l. Moreover, ATL-III can inhibit the invasion and migration of cells induced by TGF-β1, as well as block the EMT process. It was found that ATL-III could also activate the AMPK pathway. Furthermore, compound C reduced the inhibitory effect of ATL-III on stimulated cells, which indicated that the AMPK pathway plays a role in the inhibition process. In conclusion, ATL-III may inhibit the EMT of IEC-6 cells stimulated with TGF-β1 by activating the AMPK signaling pathway.

Abstract
Up to 50% of patients with Crohn's disease (CD) experience secondary loss of response (SLR) to infliximab. Patients with SLR may show clinical signs of iron deficiency as a result of inflammation despite being iron-replete. The magnetic resonance imaging (MRI)-based radiomic index, R2*, can detect changes in iron metabolism. Therefore, the R2* parameter has considerable potential for detection of SLR to infliximab. The aims of this study were to explore the correlation between R2* and inflammation and to develop a non-invasive nomogram based on R2* to identify SLR to infliximab in patients with CD. Three hundred and twenty-two infliximab-treated patients with CD who underwent magnetic resonance enterography within 2 weeks before or after 54 weeks of infliximab therapy were divided into training and validation datasets at a ratio of 8:2. Point-biserial analysis was conducted to confirm the relationship between R2* and inflammation. A multivariate logistic regression model was created using R2*, CRP and hemoglobin (OR, 1.10, 1.04 and 0.98; P < 0.05). Receiver-operating characteristic curves and the Hosmer-Lemeshow test were used to assess the performance of the model. A correlation between R2* and inflammation was identified. Different trends in R2* and iron status indices were observed between patients with responsive and non-responsive CD, which is worthy of further study. The model was converted to a visualized nomogram that had a good ability to discriminate the outcomes of infliximab therapy with an area under the curve of 0.723 (95% CI, 0.661-0.785) in the training dataset and 0.715 (95% CI, 0.587-0.843) in the validation dataset. We confirmed a correlation between R2* and inflammation in patients with CD. Based on the MRI-based radiomic signature, a novel nomogram was established and validated to facilitate individualized identification of SLR to infliximab in patients with CD.

Preoperative prevalence and risk factors of deep-vein thrombosis in Japanese surgical patients with ulcerative colitis: a retrospective investigational study. Surg Today 2021; 52:251-259. [PMID: 34236523 DOI: 10.1007/s00595-021-02335-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Accepted: 05/04/2021] [Indexed: 12/27/2022]
Abstract
PURPOSE The purpose of this study was to clarify the perioperative deep-vein thrombosis (DVT) prevalence and its risk factors in surgical ulcerative colitis (UC) patients by comparing the results with those in surgical colorectal cancer (CRC) patients at a high risk of perioperative venous thrombosis. METHODS This retrospective, observational study included patients who underwent surgery for UC or CRC between January 2013 and October 2019. Consecutive surgical patients with a positive D-dimer assay result (≥ 1.0 µg/ml) underwent lower-extremity venous ultrasonography. The prevalence and risk factors for preoperative DVT were examined in UC patients. RESULTS A total of 101 UC patients and 593 CRC patients were deemed eligible. Among the D-dimer positive cases, there were no significant differences between the two groups in the preoperative DVT prevalence (UC: 21.8% vs. CRC: 28.8%, p = 0.151), distal type (18.8% vs. 27.2%, p = 0.086), or proximal type (5.9% vs. 4.2%, p = 0.434). Furthermore, multivariate analyses showed that an older age, overweight status, poor ASA status, and a high preoperative dose of steroid were independent risk factors for preoperative DVT in UC surgical patients. CONCLUSIONS The risk of perioperative thrombosis in UC patients was considered similar to that in CRC, so active thromboprophylaxis should be administered to UC patients while paying attention to bleeding. TRIAL REGISTRATION This study was registered with the Japanese Clinical Trials Registry as UMIN000042004 ( http://www.umin.ac.jp/ctr/index.htm ).

Abstract
Natural polysaccharides and their metabolites’ short chain fatty acids (SCFAs) have attracted much attention. Recently, they have shown great potential in attenuating systemic inflammation activities, especially in inflammatory bowel disease (IBD). IBD is a complex pathological process and is related to epithelial damage and microbiota imbalance in the gut. Recent studies have indicated that natural polysaccharides could improve IBD recovery by different mechanisms. They could not only influence the ratio of intestine microbiota, but also regulate the secretion levels of immunity cytokines through multiple pathways, the latter including modulation of the TLR/MAPK/NF-κB signaling pathways and stimulation of G-protein-coupled receptors. Moreover, they could increase intestinal integrity and modulate oxidative stress. In this review, recent research about how natural polysaccharides impact the pathogenesis of IBD are summarized to prove the association between polysaccharides and disease recovery, which might contribute to the secretion of inflammatory cytokines, improve intestine epithelial damage, reduce oxidative stress, sustain the balanced microenvironment of the intestines, and finally lower the risk of IBD.

Abstract
Dysregulation of the proteolytic balance is often associated with diseases. Serine proteases and matrix metalloproteases are involved in a multitude of biological processes and notably in the inflammatory response. Within the framework of digestive inflammation, several studies have stressed the role of serine proteases and matrix metalloproteases (MMPs) as key actors in its pathogenesis and pointed to the unbalance between these proteases and their respective inhibitors. Substantial efforts have been made in developing new inhibitors, some of which have reached clinical trial phases, notwithstanding that unwanted side effects remain a major issue. However, studies on the proteolytic imbalance and inhibitors conception are directed toward host serine/MMPs proteases revealing a hitherto overlooked factor, the potential contribution of their bacterial counterpart. In this review, we highlight the role of proteolytic imbalance in human digestive inflammation focusing on serine proteases and MMPs and their respective inhibitors considering both host and bacterial origin.

Abstract
AIM Recurrence after surgery for Crohn's disease is common. Anastomotic configuration may influence recurrence and the mesentery may be key. Recently the Kono-S anastomosis and radical mesenteric excision have been proposed as methods of reducing recurrence. We analysed the literature pertaining to these novel techniques. METHOD We searched MEDLINE, Embase and the Cochrane Library for, and selected, studies evaluating Kono-S anastomosis and/or radical mesenteric excision in Crohn's disease. We assessed methodological quality and risk of bias using the Cochrane risk of bias tool for randomized controlled trials and the Joanna Briggs Institute tool for nonrandomized trials. A narrative synthesis was used to summarize the findings. RESULTS Nine studies (896 patients) were identified. Apart from one randomized controlled trial with a low risk of bias the overall level of evidence was poor (Grade IV). The Kono-S anastomosis was associated with a lower incidence of endoscopic and surgical recurrence (0%-3.4% vs 15%-24.4% respectively). Complications, particularly anastomotic leak rate, were also lower (1.8% vs 9.3% respectively). Evidence from a single poor quality study suggested that mesenteric excision may reduce surgical recurrence rates compared with mesentery preservation. CONCLUSION The existing literature suggests that the Kono-S anastomosis is safe and may reduce endoscopic and surgical recurrence, but level of evidence is mainly poor. One element of the Kono-S technique, preservation of the mesentery, may be detrimental to recurrence. Further, higher quality, studies are required to investigate these techniques. Such studies should consider the impact of the degree of mesenteric resection in addition to the anastomosis on disease recurrence.

Abstract
BACKGROUND/AIMS The inflammatory bowel diseases (IBD), ulcerative colitis (UC), and Crohn's disease (CD) are chronic diseases mostly affecting young patients. As they are diseases accompanying patients for their entire life, and the quality of life (QUOL) interacts with disease activity, improving QUOL should be one of the main goals of therapy. This study aims to identify factors contributing to good or impaired QUOL. METHODS Questionnaires addressing health-related QUOL and other psychological and social features were positioned on our institutions' webpage and on the webpage of the largest self-help group for IBD in Germany. Patients were subdivided according to their QUOL score with a cutoff of <60. We used the Short Inflammatory Bowel Disease Questionnaire, the Assessment of the Demand for Additional Psychological Treatment, and the Fear of Progression Questionnaire Short Form. RESULTS High numbers of patients in both subgroups showed an impaired QUOL (87.34% in UC, 91.08% in CD). Active extraintestinal manifestations, smoking, high fear of progression and high demand for psychotherapy were associated with reduced QUOL. In addition, polypharmacological interventions did not result in a good QUOL, but ostomies are linked to improved QUOL especially in CD patients. CONCLUSIONS Scores used in clinical day-to-day-practice mainly focusing on somatic factors do not sufficiently address important aspects concerning QUOL. Most importantly, extraintestinal manifestations show a hitherto underestimated impact on QUOL.

Modified two-stage restorative proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis: a systematic review and meta-analysis of observational research. Int J Colorectal Dis 2020; 35:1817-1830.

Abstract
PURPOSE Restorative proctocolectomy (RPC) is performed for patients with refractory ulcerative colitis (UC). This operation is performed in 2 or 3 stages and involves forming a diverting loop ileostomy thought to protect patients from complications related to anastomotic leak. However, some advocate for a modified 2-stage approach, consisting of subtotal colectomy followed by completion proctectomy and ileal pouch anal anastomosis without diverting ileostomy. We present a systematic review and meta-analysis comparing postoperative complication rates between modified 2-stage and traditional RPC with ileal pouch anal anastomosis. METHODS Records were sourced from PubMed/Embase databases. Studies comparing postoperative complications following RPC for ulcerative colitis (UC) were selected according to PRISMA guidelines comparing modified 2-stage (exposure), classic 2-stage, and 3-stage approaches (comparators). The primary outcome measure was safety as measured by postoperative complication rates. We employed random effects meta-analysis. RESULTS We included ten observational studies including 1727 patients (38% modified 2-stage). Among pediatric patients, modified 2-stage approaches had higher rates of anastomotic leak than 3-stage approaches (p = 0.03). Among adult cohorts with lower preoperative biologic use rates, modified 2-stage approaches had lower leak rates than classic 2-stage approaches (p < 0.001). CONCLUSIONS The modified 2-stage approach may be safe for adult patients who otherwise require a 3-stage approach while reducing costs and length of stay. Pediatric patients may benefit from lower leak rates when receiving 3-stage compared with modified 2-stage approaches, especially when on biologics. The modified 2-stage approach may be safer than the classic 2-stage approach for adult patients with lower biologic exposure.

Abstract
More than 80% of patients with Crohn's disease (CD) will require surgical intervention during their lifetime, with high rates of anastomotic recurrence and stenosis necessitating repeat surgery. Current data show that pharmacotherapy has not significantly improved the natural history of postoperative clinical and surgical recurrence of CD. In 2003, antimesenteric hand-sewn functional end-to-end (Kono-S) anastomosis was first performed in Japan. This technique has yielded very desirable outcomes in terms of reducing the incidence of anastomotic surgical recurrence. The most recent follow-up of these patients showed that very few had developed surgical recurrence. This new approach is superior to stapled functional end-to-end anastomosis because the stumps are sutured together to create a stabilizing structure (a "supporting column"), serving as a supportive backbone of the anastomosis to help prevent distortion of the anastomotic lumen due to disease recurrence and subsequent clinical symptoms. This technique requires careful mesenteric excision for optimal preservation of the blood supply and innervation. It also results in a very wide anastomotic lumen on the antimesenteric side. The Kono-S technique has shown efficacy in preventing surgical recurrence and the potential to become the new standard of care for intestinal CD.

Abstract
The Ficus carica polysaccharide (FCPS) components of the common fig fruit have been demonstrated to exhibit antioxidant and immunity-enhancing activities. However, it is unclear whether it could prevent the ulcerative colitis development. Here, we reported that 5 week orally administered FCPS (150-300 mg per kg bw) significantly prevented DSS-induced colitis in C57BL/6J mice by improving the colon length and suppressing the infiltration of inflammatory cells in the gut. FCPS treatment protected the goblet cells, elevated the expression of tight junction protein claudin-1, and suppressed the formation of cytokines including TNF-α and IL-1β. FCPS supplementation significantly reformed the gut microbiome by enhancing the abundance of S24-7, Bacteroides, and Coprococus, and suppressing the abundance of Escherichia and Clostridium at the genus level. Consistently, the formation of beneficial microbial metabolites, short chain fatty acids, especially acetate and butyrate, were improved in FCPS-treated colitis mice. The correlation analysis indicated that the protective effects of FCPS on ulcerative colitis might be highly correlated with the microbiota composition changes and the formation of SCFAs. In conclusion, these results indicated that FCPS supplementation could be a promising nutritional strategy for reducing inflammatory bowel disease and the gut microbes play essential roles in providing these beneficial effects.

Abstract
BACKGROUND AND AIMS Patients with inflammatory bowel diseases may have higher incidences of non-melanoma skin cancers and non-Hodgkin lymphoma, potentially linked to underlying disease and treatments. This analysis assessed incidence rates of these malignancies in Japanese patients with ulcerative colitis or Crohn's disease, and their association with thiopurine and/or anti-tumor necrosis factor-α treatment, using data from a nationwide administrative database in Japan. METHODS Patients diagnosed with inflammatory bowel disease without malignancy were identified from the Medical Data Vision database. Incident cases of non-melanoma skin cancers and non-Hodgkin lymphoma diagnosed after prescription of thiopurine and/or anti-tumor necrosis factor-α were identified between April 2008 and January 2018. Age- and sex-adjusted incidence rate ratios were calculated relative to the total treated patient population. RESULTS A total of 75 673 eligible patients were identified at the index date. Thiopurine prescription with or without anti-tumor necrosis factor-α agents increased incidence rate ratios for non-melanoma skin cancers relative to the overall population (3.39 and 4.03, respectively). There were no notable differences in non-Hodgkin lymphoma incidence relative to the total population in any treatment subgroup, regardless of prescription of thiopurine and/or anti-tumor necrosis factor-α (all incidence rate ratios, ~1). CONCLUSIONS There is no evidence for an increased incidence of non-Hodgkin lymphoma attributable to thiopurine or anti-tumor necrosis factor-α treatment in Japanese patients with inflammatory bowel disease. The impact of racial differences on non-Hodgkin lymphoma incidences should be considered. Thiopurine therapy may be a risk factor for non-melanoma skin cancers in Japanese patients.

Abstract
PURPOSES The incidence of postoperative complication is higher in Crohn's disease (CD) compared with other intestinal disease. There is less published data yet on the comparison of risk factors to predict postoperative complications in CD exposed and unexposed to previous infliximab therapy. Also the relationship between infliximab and postoperative infectious complications is still controversial. Our aim is to compare the risk factors to predict infectious complications in CD with and without preoperative infliximab and to clarify relationship between infliximab and infectious complications. METHODS This retrospective study included 390 patients from June 2014 to June 2018. Postoperative complications were compared in patients with and without preoperative infliximab. Univariate and multivariable analyses were performed to identify risk factors. RESULTS Eighty-five patients received infliximab within 8 weeks of surgery. A total of 129 patients had postoperative complications, with 35 receiving infliximab. No significant differences of whole postoperative complications were found in CD with and without infliximab (p = 0.073). However, patients receiving infliximab suffered more infectious complications (p = 0.010). Preoperative infliximab was confirmed to be an independent risk factor in infectious complications (p = 0.042). Multivariate analysis suggested that increased erythrocyte sedimentation rate (ESR) was an independent risk factor for infectious complications in patients receiving preoperative infliximab (p = 0.022), and increased C-reactive protein was an independent risk factor in patients not receiving preoperative infliximab (p = 0.019). CONCLUSIONS Preoperative use of infliximab ≤ 8 weeks was independently associated with infectious complications in CD. Risk factors were different in predicting postoperative complications in CD with and without infliximab, and preoperative ESR and C-reactive protein were risk factors, respectively.

Abstract
Serine proteases are extensively known to play key roles in many physiological processes. However, their dysregulation is often associated to several diseases including inflammatory bowel diseases (IBD). Here, we used specific substrates to monitor fecal protease activities in a large cohort of healthy and IBD patients. Of interest, serine protease activity was 10-fold higher in IBD fecal samples compared to healthy controls. Moreover, functional analysis of these fecal proteolytic activities revealed that the most increased activities are trypsin-like, elastase-like and cathepsin G-like. We also show for the first time, an increase of proteinase 3-like activity in these samples compared to controls. Results presented here will guide further investigations to better understand the relevance of these peptidases in IBD.

Abstract
Background and Aim The prevalence of ulcerative colitis has increased in Asian populations in recent years. This Japanese internet survey investigated the symptoms, impact, and treatment of ulcerative colitis, and communication between patients and medical professionals. Methods This was a non-interventional analysis of responses from participants with ulcerative colitis who had regularly visited medical providers for their disease in the past year. Results In 501 evaluable participants, the mean age was 39.8 years and mean disease duration was 7.6 years. Ulcerative colitis had a "significant impact" on daily life in 43.5% of participants who experienced bowel urgency and 48.6% who experienced bowel incontinence. Although the prevalence of bowel urgency and bowel incontinence was associated with higher stool frequency and rectal bleeding scores (p value for trend <0.0001), they still existed even in patients without frequent stools or rectal bleeding. Around 30% of participants hesitated to discuss symptoms such as bowel incontinence with a medical professional. Approximately three-quarters preferred to use websites for medical information. Most participants (78.0%) had used topical treatments. However, 25.7% were hesitant to use such treatments due to concerns about discomfort (48.1%) and administration difficulty (47.3%). Conclusions Ulcerative colitis significantly affects daily life, largely due to symptoms such as bowel urgency and bowel incontinence. Despite desiring to improve bowel incontinence, patients are embarrassed to consult physicians or nurses. Therefore, medical professionals should make an active effort to draw out patients' individual concerns, including symptoms that patients may not initially feel able to talk about openly.

Abstract
Background Adrenomedullin (AM), an endogenous vasodilative peptide, has immunomodulative effects and acts as an accelerator of mucosal regeneration in the digestive tract. AM has shown beneficial effects in rodent models of inflammatory bowel disease and patients with ulcerative colitis. The present study aimed to evaluate the pharmacodynamic properties and safety of AM in healthy male adults in a phase 1 clinical trial. Methods This phase 1, randomized, double-blind, single-center study was conducted on healthy males aged 20–65 years. Subjects received either a placebo, 3 ng/kg/min AM, 9 ng/kg/min AM, or 15 ng/kg/min AM via continuous 12-h intravenous infusion. Other subjects received either placebo or 15 ng/kg/min AM for 8 h per day for 7 days. Adverse events (AEs), vital signs, physical examinations, laboratory tests, electrocardiograms (ECG), and pharmacokinetics were assessed. Findings All 24 subjects in the single-dose test completed the study. Of the 12 subjects in multiple dosing test, one from the AM group withdrew owing to a headache. No serious AEs were reported. Hemodynamic parameters were well maintained in all subjects. Slight ECG abnormalities were observed in the single-dose test. The plasma concentration of AM progressively increased in a dose-dependent manner and reached Cmax at the end of administration. Plasma AM rapidly returned to baseline concentrations after termination, with a T1/2 of under 60 min. Interpretation This is the first phase 1 trial in healthy men evaluating the safety of AM. Our results demonstrate the safety and tolerability of AM for subsequent Phase 2 trials.

Abstract
This review outlines current topics on the surgical treatment of benign colorectal diseases, with a focus on inflammatory bowel disease (IBD) and diverticulitis. Treatment options for IBD and diverticulitis have evolved in the last few years as a result of medical advances in technology and new clinical trials. Therefore, treatment options and strategies need to be updated to provide optimal care for patients. The purpose of this review is to elucidate recent global trends and update the surgical treatment strategy for IBD and diverticulitis based on literature published in the past 2 years. Prevalence of IBD, including ulcerative colitis and Crohn's disease, has increased over the last few decades. During this period, many new medical therapies were introduced for the treatment of IBD, including biological therapy, immunomodulators, and leukocyte apheresis therapy. As a result, new surgical strategies for IBD are required. In order to improve surgical outcomes in IBD patients, the influence of preoperative treatment on postoperative complications needs to be considered. The incidence of diverticulitis is also increasing with lifestyle changes and increasing numbers of older people. For diverticulitis with perforation and generalized peritonitis, surgery is the gold standard. Elective surgery after conservative treatment of diverticulitis is also an option because of high recurrence rates. With an increase in diverticulitis, systematic strategies are essential for an appropriate approach to diverticulitis, taking into account various factors, including the patient's background.
