Front Psychiatry 2023; 14:1029467. [PMID: 37547213 PMCID: PMC10400767 DOI: 10.3389/fpsyt.2023.1029467] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2022] [Accepted: 07/06/2023] [Indexed: 08/08/2023] Open
Abstract
Background Anxiety and depression symptoms are very common in patients with inflammatory bowel disease (IBD). We aimed to explore the impact of anxiety and depression on the efficacy of medications, as well as IBD-related poor outcomes. Method This was a prospective longitudinal observational study. Hospital Anxiety and Depression Scale was used to assess anxiety and depression symptoms. Logistic regression analyses were used to assess the association between anxiety/depression and the response to different medications. Kaplan-Meier survival analysis and Cox regression model were applied to analyze the relationship between anxiety/depression and IBD-related poor outcomes, which were defined as urgent IBD-related hospitalization, IBD-related surgery, or death. Results A total of 325 IBD patients were enrolled, 118 of whom were treated with corticosteroids, 88 with azathioprine/6-mercaptopurine (AZA/6-MP), and 147 with anti-TNF agents. Anxiety/depression symptoms were found to be significantly related to steroid resistance, but independent of AZA/6-MP and anti-TNF agents nonresponse. There was a significant association between anxiety/depression symptoms and IBD-related poor outcomes. Coexisting with anxiety/depression symptoms was an independent influencing factor of steroid resistance and IBD-related poor outcomes. Conclusion IBD patients with anxiety/depression symptoms were at a higher risk of developing steroid resistance and IBD-related poor outcomes. Future studies are needed to explore whether interventions for anxiety and depression will improve their response to medications and change their prognosis.

Abstract
Recent findings suggest a key role for reactive oxygen species (ROS) in the pathogenesis and progression of ulcerative colitis (UC). Several studies have also highlighted the efficacy of citrate functionalized Mn3O4 nanoparticles as redox medicine against a number of ROS-mediated disorders. Here we show that synthesized nanoparticles consisting of chitosan functionalized tri-manganese tetroxide (Mn3O4) can restore redox balance in a mouse model of UC induced by dextran sulfate sodium (DSS). Our in-vitro characterization of the developed nanoparticle confirms critical electronic transitions in the nanoparticle to be important for the redox buffering activity in the animal model. A careful administration of the developed nanoparticle not only reduces inflammatory markers in the animals, but also reduces the mortality rate from the induced disease. This study provides a proof of concept for the use of nanomaterial with synergistic anti-inflammatory and redox buffering capacity to prevent and treat ulcerative colitis.

Abstract
Ulcerative colitis is a chronic inflammatory disease which poorly affects the colon and spreads toward the rectum over time. Cortisone (CRT) is a corticosteroid clinically used for the management of inflammatory diseases like colitis and other inflammatory bowel diseases. Due to some physicochemical properties' cortisone has limited potency in clinics. To overcome drug-related problems, we successfully prepared lipid nanocarriers with generally regarded as safe (GRAS) materials approved by USFDA. The present study aimed to assess the therapeutic efficacy of CRT-loaded 6-o-stearoyl ascorbic acid (SAA) nanostructured lipid carriers (NLCs) against DSS-induced colitis mice. Formulation and characterizations of reported nanostructured lipid carrier were performed according to our previously optimized parameters. The average hydrodynamic diameter of NLCs was 182 nm as measured by DLS with 81.14 % encapsulation efficacy. TEM, AFM and SEM images analysis confirmed its spherical appearance. hTERT-BJ cells viability up to a dose of 500 μg/ml shows cytocompatible characteristics of blank NLCs. CRT-loaded NLCs treatment normalizes physically observed parameters such as disease activity index, weight variation etc. These NLCs were able to significantly reduce the severity of colitis in terms of colon histoarchitecture, regaining of the goblet cells, mucins secretions, inhibition of proinflammatory cytokines etc. Treatment with CRT-loaded NLCs effectively downregulated the overexpression of inflammatory enzymes like cyclooxygenase-2 (COX-2), Inducible nitric oxide synthase (iNOS) etc. The results of this study concluded that these CRT-encapsulated NLCs efficiently manage the disease severity induced by DSS.

Abstract
Inflammatory bowel diseases (IBD) encompass two main entities including ulcerative colitis and Crohn's disease. Although having a common global pathophysiological mechanism, IBD patients are characterized by a significant interindividual heterogeneity and may differ by their disease type, disease locations, disease behaviours, disease manifestations, disease course as well as treatment needs. Indeed, although the therapeutic armamentarium for these diseases has expanded rapidly in recent years, a proportion of patients remains with a suboptimal response to medical treatment due to primary non-response, secondary loss of response or intolerance to currently available drugs. Identifying, prior to treatment initiation, which patients are likely to respond to a specific drug would improve the disease management, avoid unnecessary side effects and reduce the healthcare expenses. Precision medicine classifies individuals into subpopulations according to clinical and molecular characteristics with the objective to tailor preventative and therapeutic interventions to the characteristics of each patient. Interventions would thus be performed only on those who will benefit, sparing side effects and expense for those who will not. This review aims to summarize clinical factors, biomarkers (genetic, transcriptomic, proteomic, metabolic, radiomic or from the microbiota) and tools that could predict disease progression to guide towards a step-up or top-down strategy. Predictive factors of response or non-response to treatment will then be reviewed, followed by a discussion about the optimal dose of drug required for patients. The time at which these treatments should be administered (or rather can be stopped in case of a deep remission or in the aftermath of a surgery) will also be addressed. IBD remain biologically complex, with multifactorial etiopathology, clinical heterogeneity as well as temporal and therapeutic variabilities, which makes precision medicine especially challenging in this area. Although applied for many years in oncology, it remains an unmet medical need in IBD.

Abstract
Background Inflammatory bowel disease (IBD) is a chronic relapsing-remitting disease. An adverse immune reaction toward the intestinal microbiota is involved in the pathophysiology and microbial perturbations are associated with IBD in general and with flares specifically. Although medical drugs are the cornerstone of current treatment, responses vary widely between patients and drugs. The intestinal microbiota can metabolize medical drugs, which may influence IBD drug (non-)response and side effects. Conversely, several drugs can impact the intestinal microbiota and thereby host effects. This review provides a comprehensive overview of current evidence on bidirectional interactions between the microbiota and relevant IBD drugs (pharmacomicrobiomics). Methods Electronic literature searches were conducted in PubMed, Web of Science and Cochrane databases to identify relevant publications. Studies reporting on microbiota composition and/or drug metabolism were included. Results The intestinal microbiota can both enzymatically activate IBD pro-drugs (e.g., in case of thiopurines), but also inactivate certain drugs (e.g., mesalazine by acetylation via N-acetyltransferase 1 and infliximab via IgG-degrading enzymes). Aminosalicylates, corticosteroids, thiopurines, calcineurin inhibitors, anti-tumor necrosis factor biologicals and tofacitinib were all reported to alter the intestinal microbiota composition, including changes in microbial diversity and/or relative abundances of various microbial taxa. Conclusion Various lines of evidence have shown the ability of the intestinal microbiota to interfere with IBD drugs and vice versa. These interactions can influence treatment response, but well-designed clinical studies and combined in vivo and ex vivo models are needed to achieve consistent findings and evaluate clinical relevance.

Enteric-Coated Cologrit Tablet Exhibit Robust Anti-Inflammatory Response in Ulcerative Colitis-like In-Vitro Models by Attuning NFκB-Centric Signaling Axis. Pharmaceuticals (Basel) 2022; 16:ph16010063. [PMID: 36678560 PMCID: PMC9862254 DOI: 10.3390/ph16010063] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 12/24/2022] [Accepted: 12/28/2022] [Indexed: 01/03/2023] Open
Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease that affects the patients' colorectal area culminating in an inflamed 'leaky gut.' The majority of UC treatments only provide temporary respite leading to its relapse. Therefore, this study investigated the efficacy of the enteric-coated 'Cologrit' (EC) tablet in alleviating UC-like inflammation. Cologrit is formulated using polyherbal extracts that have anti-inflammatory qualities according to ancient Ayurveda scriptures. Phytochemical profiling revealed the presence of gallic acid, rutin, ellagic acid, and imperatorin in Cologrit formulation. Cologrit treatment decreased inflammation in LPS-induced transformed THP-1 macrophages, and TNF-α-stimulated human colorectal (HT-29) cells through the modulation of NFκB activity, IL-6 production, and NFκB, IL-1β, IL-8, and CXCL5 mRNA expression levels. Cologrit also lessened human monocytic (U937) cell adhesion to HT29 cells. Methacrylic acid-ethylacrylate copolymer-coating of the enteric Cologrit tablets (EC) supported their dissolution, and the release of phytochemicals in the small intestine pH 7.0 environment in a simulated gastrointestinal digestion model. Small intestine EC digestae effectively abridged dextran sodium sulfate (2.5% w/v)-induced cell viability loss and oxidative stress in human colon epithelial Caco-2 cells. In conclusion, the enteric-coated Cologrit tablets demonstrated good small intestine-specific phytochemical delivery capability, and decreased UC-like inflammation, and oxidative stress through the regulation of TNF-α/NFκB/IL6 signaling axis.

Abstract
BACKGROUND Patients with ulcerative colitis may require colectomy for severe disease unresponsive or refractory to pharmacological therapy. Managing ulcerative colitis is complicated because there are many factors at play, including patient optimization and treatment, as the guidance varies on the ideal perioperative use of corticosteroids, immunomodulators, biologics, and small molecule agents. OBJECTIVE A systematic literature review was performed to describe the current status of perioperative management of ulcerative colitis. DATA SOURCES PubMed and Cochrane databases were used. STUDY SELECTION Studies published between January 2000 and January 2022, in any language, were included. Articles regarding pediatric or endoscopic management were excluded. INTERVENTIONS Perioperative management of ulcerative colitis was included. MAIN OUTCOME MEASURES Successful management, including reducing surgical complication rates, was measured. RESULTS A total of 121 studies were included in this review, including 23 meta-analyses or systematic reviews, 25 reviews, and 51 cohort studies. LIMITATIONS Qualitative review including all study types. The varied nature of study types precludes quantitative comparison. CONCLUSION Indications for colectomy in ulcerative colitis include severe disease unresponsive to medical treatment and colitis-associated neoplasia. Urgent colectomy has a higher mortality rate than elective colectomy. Corticosteroids are associated with postsurgical infectious complications and should be stopped or weaned before surgery. Biologics are not associated with adverse postoperative effects and do not necessarily need to be stopped preoperatively. Additionally, the clinician must assess individuals' comorbidities, nutrition status, and risk of venous thromboembolism. Nutritional imbalance should be corrected, ideally at the preoperative period. Postoperatively, corticosteroids can be tapered on the basis of the length of preoperative corticosteroid use.

Abstract
Inflammatory bowel disease (IBD) is a chronic immune-mediated inflammation of the gastrointestinal tract with a highly heterogeneous presentation. It has a relapsing and remitting clinical course that necessitates lifelong monitoring and treatment. Although the availability of a variety of effective therapeutic options including immunomodulators and biologics (such as TNF, CAM inhibitors) has led to a paradigm shift in the treatment outcomes and clinical management of IBD patients, some patients still either fail to respond or lose their responsiveness to therapy over time. Therefore, according to the recent Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE-II) recommendations, continuous disease monitoring from symptomatic relief to endoscopic healing along with short- and long-term therapeutic responses are critical for providing IBD patients with a tailored therapy algorithm. Moreover, considering the high unmet need for novel therapeutic approaches for IBD patients, various new modulators of cytokine signaling events (for example, JAK/TYK inhibitors), inhibitors of cytokines (for example IL-12/IL-23, IL-22, IL-36, and IL-6 inhibitors), anti-adhesion and migration strategies (for example, β7 integrin, sphingosine 1-phosphate receptors, and stem cells), as well as microbial-based therapeutics to decolonize the bed buds (for example, fecal microbiota transplantation and bacterial inhibitors) are currently being evaluated in different phases of controlled clinical trials. This review aims to offer a comprehensive overview of available treatment options and emerging therapeutic approaches for IBD patients. Furthermore, predictive biomarkers for monitoring the therapeutic response to different IBD therapies are also discussed.

Abstract
Musa acuminata (MA) is a popular fruit peels in the world. Non-food parts of the plant have been investigated for their antioxidant and anti-ulcerative colitis activity. Metabolomic approaches were found to be informative as a screening tool. It discovered different metabolites depending on statistical analysis. The antioxidant activity content was measured by colorimetric method. Seventy six investigated metabolites were observed. The identities of some of these markers were confirmed based on their MS2 fragmentation and NMR spectroscopy. These include: cinnamic acid and its dimer 2-hydroxy-4-(4-methoxyphenyl)-1H-phenalen-1-one beside; gallic acid and flavonoids; quercetin, quercetin-3-O-β-d-glucoside, luteolin-7-O-β-d-glucopyranoside. GC/MS analysis of MA peels essential oil led to identification of 37 compounds. The leaves, pseudostem and fruit peels extracts were tested for their safety and their anti-ulcerative colitis efficacy in rats. Rats were classified into: normal, positive, prednisolone reference group, MA extracts pretreated groups (250–500 mg/kg) for 2 weeks followed by induction of ulcerative colitis by per-rectal infusion of 8% acetic acid. Macroscopic and microscopic examinations were done. Inflammatory markers (ANCA, CRP and Ilβ6) were measured in sera. The butanol extracts showed good antioxidant and anti-inflammatory activities as they ameliorated macroscopic and microscopic signs of ulcerative colitis and lowered the inflammatory markers compared to untreated group. MA wastes can be a potential source of bioactive metabolites for industrial use and future employment as promising anti-ulcerative colitis food supplements.

Abstract
Inflammatory bowel disease (IBD), as a global disease, has attracted much research interest. Constant research has led to a better understanding of the disease condition and further promoted its management. We here reviewed the conventional and the novel drugs and therapies, as well as the potential ones, which have shown promise in preclinical studies and are likely to be effective future therapies. The conventional treatments aim at controlling symptoms through pharmacotherapy, including aminosalicylates, corticosteroids, immunomodulators, and biologics, with other general measures and/or surgical resection if necessary. However, a considerable fraction of patients do not respond to available treatments or lose response, which calls for new therapeutic strategies. Diverse therapeutic options are emerging, involving small molecules, apheresis therapy, improved intestinal microecology, cell therapy, and exosome therapy. In addition, patient education partly upgrades the efficacy of IBD treatment. Recent advances in the management of IBD have led to a paradigm shift in the treatment goals, from targeting symptom-free daily life to shooting for mucosal healing. In this review, the latest progress in IBD treatment is summarized to understand the advantages, pitfalls, and research prospects of different drugs and therapies and to provide a basis for the clinical decision and further research of IBD.

World J Gastroenterol 2021; 27:3609-3629. [PMID: 34239273 PMCID: PMC8240054 DOI: 10.3748/wjg.v27.i24.3609] [Citation(s) in RCA: 49] [Impact Index Per Article: 16.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2021] [Revised: 03/22/2021] [Accepted: 05/25/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Gut microbiota and its metabolites may be involved in the pathogenesis of inflammatory bowel disease. Several clinical studies have recently shown that patients with ulcerative colitis (UC) have altered profiles of fecal bile acids (BAs). It was observed that BA receptors Takeda G-protein-coupled receptor 5 (TGR5) and vitamin D receptor (VDR) participate in intestinal inflammatory responses by regulating NF-ĸB signaling. We hypothesized that altered profiles of fecal BAs might be correlated with gut microbiota and inflammatory responses in patients with UC. AIM To investigate the changes in fecal BAs and analyze the relationship of BAs with gut microbiota and inflammation in patients with UC. METHODS The present study used 16S rDNA sequencing technology to detect the differences in the intestinal flora between UC patients and healthy controls (HCs). Fecal BAs were measured by targeted metabolomics approaches. Mucosal TGR5 and VDR expression was analyzed using immunohistochemistry, and serum inflammatory cytokine levels were detected by ELISA. RESULTS Thirty-two UC patients and twenty-three HCs were enrolled in this study. It was found that the diversity of gut microbiota in UC patients was reduced compared with that in HCs. Firmicutes, Clostridium IV, Butyricicoccus, Clostridium XlVa, Faecalibacterium, and Roseburia were significantly decreased in patients with UC (P = 3.75E-05, P = 8.28E-07, P = 0.0002, P = 0.003, P = 0.0003, and P = 0.0004, respectively). Proteobacteria, Escherichia, Enterococcus, Klebsiella, and Streptococcus were significantly enriched in the UC group (P = 2.99E-09, P = 3.63E-05, P = 8.59E-05, P = 0.003, and P = 0.016, respectively). The concentrations of fecal secondary BAs, such as lithocholic acid, deoxycholic acid, glycodeoxycholic acid, glycolithocholic acid, and taurolithocholate, in UC patients were significantly lower than those in HCs (P = 8.1E-08, P = 1.2E-07, P = 3.5E-04, P = 1.9E-03, and P = 1.8E-02, respectively) and were positively correlated with Butyricicoccus, Roseburia, Clostridium IV, Faecalibacterium, and Clostridium XlVb (P < 0.01). The concentrations of primary BAs, such as taurocholic acid, cholic acid, taurochenodeoxycholate, and glycochenodeoxycholate, in UC patients were significantly higher than those in HCs (P = 5.3E-03, P = 4E-02, P = 0.042, and P = 0.045, respectively) and were positively related to Enterococcus, Klebsiella, Streptococcus, Lactobacillus, and pro-inflammatory cytokines (P < 0.01). The expression of TGR5 was significantly elevated in UC patients (0.019 ± 0.013 vs 0.006 ± 0.003, P = 0.0003). VDR expression in colonic mucosal specimens was significantly decreased in UC patients (0.011 ± 0.007 vs 0.016 ± 0.004, P = 0.033). CONCLUSION Fecal BA profiles are closely related to the gut microbiota and serum inflammatory cytokines. Dysregulation of the gut microbiota and altered constitution of fecal BAs may participate in regulating inflammatory responses via the BA receptors TGR5 and VDR.

Abstract
BACKGROUND Inflammatory bowel diseases (IBD), which include Crohn disease and ulcerative colitis, affect several million individuals worldwide. Curcumin as a complementary therapy has been used to cure the IBD, yet the efficacy and safety of curcumin remains to be assessed. In this study, we aim to draw up a protocol for systematic review to evaluate the efficacy and safety of curcumin for IBD. METHODS We will search the following electronic databases from inception to September 31, 2020: PubMed, Cochrane Library, EMBASE, Web of Science, Medline, the China National Knowledge Infrastructure Database, Wan Fang Database, the Chinese Scientific Journal Database, and Chinese Biomedical Literature Database. Clinical trial registrations, potential gray literatures, relevant conference abstracts and reference list of identified studies will also be searched. Relevant randomized controlled clinical trials were enrolled and analyzed. The literature selection, data extraction, and quality assessment will be completed by 2 independent authors. Either the fixed-effects or random-effects model will be used for data synthesis based on the heterogeneity test. Clinical remission will be evaluated as the primary outcome. Clinical response, endoscopic remission, inflammatory markers and adverse events will be assessed as the secondary outcomes. The RevManV.5.3.5 will be used for Meta-analysis. Subgroup analyses of doses, delivery way, frequency of treatment and the degree of IBD severity or different forms of IBD were also conducted. RESULTS This study will provide a synthesis of current evidence of curcumin for IBD from several aspects, such as clinical remission, clinical response, endoscopic remission, inflammatory markers, and adverse events. CONCLUSION The conclusion of our study will provide updated evidence to judge whether curcumin is an effective solution to IBD patients. INPLASY REGISTRATION NUMBER INPLASY202090065.

Nutrients 2020; 12:nu12082296. [PMID: 32751776 PMCID: PMC7468803 DOI: 10.3390/nu12082296] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 07/09/2020] [Accepted: 07/16/2020] [Indexed: 12/14/2022] Open
Abstract
The objective of this study was to systematically review the literature to verify the efficacy and safety of curcumin as a complementary therapy for the maintenance or induction of remission in patients with inflammatory bowel disease (IBD). A comprehensive search was conducted by two independent authors in MEDLINE (PubMed), Scopus, Web of Science, the Cochrane Library, Lilacs, Food Science and Technology Abstracts, and ScienceDirect. The search terms “curcumin”, “curcuma”, “inflammatory bowel disease”, “proctocolitis”, “crohn disease”, and “inflammation” were combined to create search protocols. This study considered randomized controlled trials (RCTs) published in any language before March 2020 that evaluated the effects of curcumin on inflammatory activity and the maintenance or remission of IBD patients. After duplicates were removed, 989 trials were identified, but only 11 met the eligibility criteria. Five of these were considered to be biased and were excluded. Therefore, six trials were considered in this review. All the studies included in the systematic review were placebo-controlled RCTs conducted on individuals with ulcerative colitis (UC). All the RCTs reported that curcumin was well tolerated and was not associated with any serious side effects. Studies show that curcumin may be a safe, effective therapy for maintaining remission in UC when administered with standard treatments. However, the same cannot be stated for Crohn’s disease due to the lack of low bias risk studies. Further studies with larger sample sizes are needed before curcumin can be recommended as a complementary therapy for UC.

Abstract
BACKGROUND Ulcerative colitis (UC) may require systemic corticosteroid (CS) treatment often without a reliable predictable response, except the Ho-index, used to predict severe cases. The present study aims to determine CS-efficacy and CS-free remission for different courses and longer follow-ups, and a predictive value of CS-outcomes, by the Ho-index and the analysis of clinical variables. METHODS An observational retrospective study performed with 136 patients was based on clinical and analytical characteristics, before successive CS-therapies. RESULTS The age of UC onset showed three peaks. After the first course, 55.6% were CS-responders, and 39% had CS-free remission by the 3-5-year follow-up. Successive CS-courses presented less efficacy and CS-free remissions, associated with increased CS-use dependence. The Ho-index might only predict the first course of CS and low-score patients with severe UC. Logistic regression analysis gave a predictive response mainly due to the age at diagnosis, the interval from diagnosis to CS-therapy, and C-reactive protein (CRP) or hemoglobin values. CONCLUSIONS One-third of the cases were CS-free remission UC. Successive courses showed decreased efficacy and increased CS-dependence, limiting CS-treatment. An older age at diagnosis, longer interval from diagnosis to CS-therapy, lower CRP and higher hemoglobin predicted better prognosis. The accuracy of prediction should be validated and include additional markers.

Abstract
Epidemiological studies have provided controversial evidence between beverage consumption and the risk of ulcerative colitis (UC). This study aimed to determine the role of beverage consumption in the development of UC. A systematic search was conducted in public databases to identify all relevant studies, and study-specific relative risks (RRs) and 95% confidence intervals (CIs) were pooled using a random-effects model. Sixteen studies were identified with a total of 3689 cases and 335,339 controls. Alcohol consumption showed no significant association with UC risk (RR for the highest vs the lowest consumption level: 0.95, 95% CI: 0.65-1.39). Coffee consumption tended to be inversely associated with UC risk (RR: 0.58, 95% CI: 0.33-1.05), but it was not significant and confounded by smoking adjustment. Soft drinks consumption was associated with UC risk (RR: 1.69, 95% CI: 1.24-2.30), and tea consumption was inversely associated with UC risk (RR: 0.69, 95% CI: 0.58-0.83). In conclusion, high consumption of soft drinks might increase the risk of UC, while tea consumption might decrease the risk.

Magnolol, a Natural Polyphenol, Attenuates Dextran Sulfate Sodium-Induced Colitis in Mice. Molecules 2017; 22:molecules22071218.

Abstract
Magnolol is a lignan with anti-inflammatory activity identified in Magnolia officinalis. Ulcerative colitis (UC), one of the types of inflammatory bowel disease (IBD), is a disease that causes inflammation and ulcers in the colon. To investigate the effect of magnolol in dextran sulfate sodium (DSS)-induced experimental UC model, male C57 mice were treated with 2% DSS drinking water for 5 consecutive days followed by intragastric administration with magnolol (5, 10 and 15 mg/kg) daily for 7 days. The results showed that magnolol significantly attenuated disease activity index, inhibited colonic shortening, reduced colonic lesions and suppressed myeloperoxidase (MPO) activity. Moreover, colonic pro-inflammatory cytokines (TNF-α, IL-6, and IL-1β) induced by colitis were dramatically decreased by magnolol. To further unveil the metabolic signatures upon magnolol treatment, mass spectrometry-based metabolomic analysis of the small molecular metabolites in mice serum were performed. Compared with controls, abnormality of serum metabolic phenotypes in DSS-treated mice were effectively reversed by different doses of magnolol. In particular, magnolol treatment effectively elevated the serum levels of tryptophan metabolites including kynurenic acid (KA), 5-hydroxyindoleacetic acid, indoleacetic acid (IAA), indolelactic acid and indoxylsulfuric acid, which are potential aryl hydrocarbon receptor (AHR) ligands to impact colitis. These findings suggest that magnolol exerts anti-inflammatory effect on DSS-induced colitis and its underlying mechanisms are associated with the restoring of tryptophan metabolites that inhibit the colonic inflammation.

Abstract
Bortezomib, a first-in-class proteasome inhibitor, is a standard method of treatment in multiple myeloma. In the present study, the therapeutic effect of bortezomib was evaluated in an ulcerative colitis model induced by dextran sulfate sodium (DSS) in mice, and the mechanism of action was also investigated. Mice were administered with 3% DSS drinking water for 7 consecutive days and then they were intraperitoneally treated with bortezomib (0.2, 0.6 or 1 mg/kg) for 1, 3 or 7 days. Mice in the control group and the DSS group were provided the same volume of PBS, respectively. Body weight, stool characteristics and hematochezia were observed. Serum levels of tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), albumin (ALB) and colonic activity of superoxide dismutase (SOD) were evaluated using specific kits. The expression of the transcription factor nuclear factor-κB (NF-κB) p65 gene and the DNA-binding activity of NF-κB protein were also evaluated. Administration of bortezomib attenuates colonic inflammation in mice. After 3 or 7 days of treatment, Disease Activity Index (DAI) as well as histological scores and NF-κB p65 protein expression were significantly reduced in mice treated with bortezomib at a dose of 0.6 or 1 mg/kg/day. Furthermore, it was also revealed that bortezomib was able to reduce serum levels of CRP and TNF-α caused by DSS and increase the level of ALB in serum and the activity of SOD in colonic tissues. These results demonstrated that bortezomib exerts a protective effect on DSS-induced colitis, and its underlying mechanisms are associated with the NF-κB gene inhibition that mitigates colon inflammatory responses in intestinal epithelial cells.

Abstract
BACKGROUND AND AIM Fat intake is generally thought as a risk factor for onset of ulcerative colitis (UC), while epidemiological data had been controversial. This study aimed to evaluate the role of fat intake in the development of UC. METHODS Comprehensive search in PubMed and Embase was conducted to identify all relevant studies, and the role of fat intake in the development of UC was quantitatively assessed by dose-response meta-analysis. RESULTS Nine studies (four case-control and five prospective cohort) were indentified with a total of 966 UC cases and 171 589 controls. No evidence of a nonlinear dose-response association was found between fat intake and UC risk. Overall, the summary relative risks (RR) for per 30 g increment/day were 1.023 (95%confidence interval [CI]: 0.963-1.087; I2 = 24%; n = 6) for total fat intake, 1.063 (95%CI: 0.845-1.337; I2 = 44.5%; n = 4) for saturated fat intake, 1.214 (95%CI: 0.911-1.618; I2 = 63.1%; n = 4) for monounsaturated fat (MUFA) intake, and 1.247 (95%CI: 0.948-1.640; I2 = 25.4%; n = 4) for polyunsaturated fat (PUFA) intake, respectively. Subgroup and sensitivity analyses showed inconsistent results on PUFA intake, which was significantly related with UC risk after adjusting for smoking (RR: 1.617, 95%CI: 1.045-2.502; I2 = 0%; n = 3). For PUFA and MUFA subtypes, no subtypes were significantly associated with UC risk (P > 0.05), and only docosahexaenoic acid showed a potential protective effect in the development of UC (RR for the highest versus lowest intake level: 0.642, 95%CI: 0.403-1.024; I2 = 34.4%; n = 3) CONCLUSIONS: This meta-analysis suggested a lack of association between fat intake and UC risk, and large-scale prospective designed studies are warranted to confirm our findings.

Abstract
BACKGROUND & AIM Dietary carbohydrate and protein intake is generally thought as risk factors for onset of ulcerative colitis (UC), while epidemiological data had been controversial. This study aimed to evaluate the role of carbohydrate and protein intake in the development of UC. METHODS Comprehensive search in PubMed and Embase was conducted to identify all relevant studies, and the role of carbohydrate and protein intake in the development of UC was quantitatively assessed by dose-response meta-analysis. RESULTS Nine studies (5 case-control and 4 prospective cohort) were identified with a total of 975 UC cases and 239352 controls. The summary relative risks (RR) for per 10 g increment/day were 1.005 (95%CI: 0.991-1.019, I2 = 31.5%, n = 5) for total carbohydrate intake, 1.001 (95%CI: 0.971-1.032, I2 = 0.0%, n = 7) for the subtype of fiber intake, 1.029 (95%CI: 0.962-1.101, I2 = 68.9%, n = 2) for the subtype of sugar intake, and 1.010 (95%CI: 0.975-1.047, I2 = 12.4%, n = 7) for total protein intake. Among sugar subtypes, only sucrose intake was found positively related with UC risk (RR for per 10 g increment/day: 1.098, 95%CI: 1.024-1.177, I2 = 0.0%, n = 3). No evidence of a non-linear dose-response association was found between the nutrient intake and UC risk, except for the subtype of sucrose (P for non-linear trend = 0.032). Subgroup analyses showed consistent results. CONCLUSIONS This meta-analysis suggested a lack of association between dietary carbohydrate or protein intake and the risk of UC, except for the subtype of sucrose which played a significant role in the development of UC. Large-scale prospective designed studies are needed to confirm our findings.

Abstract
Introduction One of the forms of inflammatory bowel disease (IBD) that causes inflammation and ulcers in colon is ulcerative colitis (UC). This study was aimed to determine the epidemiological and clinical aspects of patients with ulcerative colitis in the west of Iran. Methods In this cross sectional study, we evaluated 150 patients with definite diagnosis of UC who referred to a subspecialty gastroenterology clinic in Khorramabad, Iran. The study was performed from May 2014 to August 2015 by using census method. Demographic characteristics as well as patients’ clinical profiles were extracted using a checklist. Disease severity was determined by the Truelove and Witt’s classification of ulcerative colitis (UC). Data were analyzed using SPSS software, version 17 for windows (IBM Inc., NY, US). Results A total of 150 patients with definite diagnosis of UC were analyzed, including 84 (56 %) women and 66 (44 %) men (male/female ratio = 1.27). The mean age of patients was 33.7 ± 12.5 years with an age range of 17–98 years. The age of the majority of patients was 20–29 and most of them (56 %) were women and living in urban areas (70.7 %). The most common site of the involvement in colon was rectosigmoid (66 patients, 44 %). Severity of the disease was mild in 36 patients (24.1 %), moderate and severe in 74 and 40 patients (49.3 and 26.6 %), respectively. The most common clinical manifestation of the patients was dysentery (68 %) and then rectorrhagia (60 %). Only 12 of all patients (7.8 %) mentioned a positive family history of IBD in their first degree kinfolks. Ten patients (6.7 %) had a history of regular smoking and four of them (2.6 %) mentioned a history of appendectomy. Four patients (5.3 %) had a positive history of smoking by their mothers during their pregnancy. Conclusion The results of this study demonstrate differences and similarities in demographic and clinical characteristics of UC in this part of Iran in comparison to other parts of the country.
