BACKGROUND Real-world data on tofacitinib(TOF)covering a period of more than 1 year for a sufficient number of Asian patients with ulcerative colitis(UC)are scarce.AIM To investigate the long-term efficacy and safety of TOF treatment for UC,including clinical issues.METHODS We performed a retrospective single-center observational analysis of 111 UC patients administered TOF at Hyogo Medical University as a tertiary inflammatory bowel disease center.All consecutive UC patients who received TOF between May 2018 and February 2020 were enrolled.Patients were followed up until August 2020.The primary outcome was the clinical response rate at week 8.Secondary outcomes included clinical remission at week 8,cumulative persistence rate of TOF administration,colectomy-free survival,relapse after tapering of TOF and predictors of clinical response at week 8 and week 48.RESULTS The clinical response and remission rates were 66.3%and 50.5%at week 8,and 47.1%and 43.5%at week 48,respectively.The overall cumulative clinical remission rate was 61.7%at week 48 and history of anti-tumor necrosis factor-alpha(TNF-α)agents use had no influence(P=0.25).The cumulative TOF persistence rate at week 48 was significantly lower in patients without clinical remission than in those with remission at week 8(30.9%vs 88.1%;P<0.001).Baseline partial Mayo Score was significantly lower in responders vs non-responders at week 8(odds ratio:0.61,95%confidence interval:0.45-0.82,P=0.001).Relapse occurred in 45.7%of patients after TOF tapering,and 85.7%of patients responded within 4 wk after re-increase.All 6 patients with herpes zoster(HZ)developed the infection after achieving remission by TOF.CONCLUSION TOF was more effective in UC patients with mild activity at baseline and its efficacy was not affected by previous treatment with anti-TNF-αagents.Most relapsed patients responded again after re-increase of TOF and nearly half relapsed after tapering off TOF.Special attention is needed for tapering and HZ. 展开更多

Ulcerative colitis(UC)is a chronic recurrent inflammatory bowel disease.Despite ongoing advances in our understanding of UC,its pathogenesis is yet unelu-cidated,underscoring the urgent need for novel treatment strategies for patients with UC.Exosomes are nanoscale membrane particles that mediate intercellular communication by carrying various bioactive molecules,such as proteins,RNAs,DNA,and metabolites.The NOD-like receptor family pyrin domain containing 3(NLRP3)inflammasome is a cytosolic tripartite protein complex whose activation induces the maturation and secretion of proinflammatory cytokines interleukin-1β(IL-1β)and IL-18,triggering the inflammatory response to a pathogenic agent or injury.Growing evidence suggests that exosomes are new modulators of the NLRP3 inflammasome,with vital roles in the pathological process of UC.Here,recent evidence is reviewed on the role of exosomes and NLRP3 inflammasome in UC.First,the dual role of exosomes on NLRP3 inflammasome and the effect of NLRP3 inflammasome on exosome secretion are summarized.Finally,an outlook on the directions of exosome-NLRP3 inflammasome crosstalk research in the context of UC is proposed and areas of further research on this topic are high-lighted. 展开更多

BACKGROUND Many patients with ulcerative colitis(UC)do not respond well to,or tolerate conventional and biological therapies.There is currently no consensus on the treatment of refractory UC.Studies have demonstrated that the selective Janus kinase 1 inhibitor upadacitinib,a small-molecule drug,is effective and safe for treating UC.However,no studies have revealed that upadacitinib is effective in treating refractory UC with primary nonresponse to infliximab and vedolizumab.CASE SUMMARY We report the case of a 44-year-old male patient with a chief complaint of bloody diarrhoea with mucus and pus,in addition to dizziness.The patient had recurrent disease after receiving mesalazine,prednisone,azathioprine,infliximab and vedolizumab over four years.Based on the endoscopic findings and pathological biopsy,the patient was diagnosed with refractory UC.In particular,the patient showed primary nonresponse to infliximab and vedolizumab.Based on the patient’s history and recurrent disease,we decided to administer upadacitinib.During hospitalisation,the patient was received upadacitinib under our guidance.Eight weeks after the initiation of upadacitinib treatment,the patient’s symptoms and endoscopic findings improved significantly.No notable adverse reactions have been reported to date.CONCLUSION Our case report suggests that upadacitinib may represent a valuable strategy for treating refractory UC with primary nonresponse. 展开更多

For ulcerative colitis(UC),the variability in inflammatory activity along the colon poses a challenge in management.The focus on achieving endoscopic healing in UC is evident,where the UC Endoscopic Index of Severity and Mayo Endoscopic Subscore are commonly used for evaluation.However,these indices primarily consider the most severely affected region.Liu et al recent study validates the Toronto Inflammatory Bowel Disease Global Endoscopic Reporting(TIGER)score offering a comprehensive assessment of inflammatory activity across diverse segments of the colon and rectum and a reliable index correlating strongly with UC Endoscopic Index of Severity and moderately with Mayo Endoscopic Subscore(MES).Despite recommendation,certain aspects warrant further invest-igation.Fecal calprotectin,an intermediate target,correlates with TIGER and should be explored.Determining TIGER scores defining endoscopic remission and response,evaluating agreement with histological activity,and assessing inter-endoscopist agreement for TIGER require scrutiny.Exploring the correlation between TIGER and intestinal ultrasound,akin to MES,adds value. 展开更多

BACKGROUND The pathogenesis of ulcerative colitis(UC)is complex,and recent therapeutic advances remain unable to fully alleviate the condition.AIM To inform the development of novel UC treatments,bioinformatics was used to explore the autophagy-related pathogenesis associated with the active phase of UC.METHODS The GEO database was searched for UC-related datasets that included healthy controls who met the screening criteria.Differential analysis was conducted to obtain differentially expressed genes(DEGs).Au-tophagy-related targets were collected and intersected with the DEGs to identiy differentially expressed autophagy-related genes(DEARGs)associated with active UC.DEARGs were then subjected to KEGG,GO,and DisGeNET disease enrichment analyses using R software.Differential analysis of immune infiltrating cells was performed using the CiberSort algorithm.The least absolute shrinkage and selection operator algorithm and protein-protein interaction network were used to narrow down the DEARGs,and the top five targets in the Dgree ranking were designated as core targets.RESULTS A total of 4822 DEGs were obtained,of which 58 were classified as DEARGs.SERPINA1,BAG3,HSPA5,CASP1,and CX3CL1 were identified as core targets.GO enrichment analysis revealed that DEARGs were primarily enriched in processes related to autophagy regulation and macroautophagy.KEGG enrichment analysis showed that DEARGs were predominantly associated with NOD-like receptor signaling and other signaling pathways.Disease enrichment analysis indicated that DEARGs were significantly linked to diseases such as malignant glioma and middle cerebral artery occlusion.Immune infiltration analysis demonstrated a higher presence of immune cells like activated memory CD4 T cells and follicular helper T cells in active UC patients than in healthy controls.CONCLUSION Autophagy is closely related to the active phase of UC and the potential targets obtained from the analysis in this study may provide new insight into the treatment of active UC patients. 展开更多

Blautia has attracted attention because of its potential efficacy in ameliorating host energy metabolism and inflammation.This study aims to investigate the influences of Blautia producta D4 on colitis induced by dextran sulfate sodium(DSS)and to reveal the underlying mechanisms.Results showed that B.producta D4 intervention significantly relieved body weight loss,and suppressed the elevation of pro-inflammatory cytokines(including interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),and interleukin-1β(IL-1β))and excessive oxidative stress(myeloperoxidease(MPO)activity,superoxide dismutase(SOD)activity,glutathione peroxidase(GSH-Px)activity,and malondialdehyde(MDA)level)in colitis mice.Moreover,the concentrations of tight junction proteins(occludin,claudin-1,and ZO-1)related to the intestinal barrier were obviously elevated,and colitis-related TLR4/NF-κB pathway activation was remarkably inhibited after B.producta D4 intervention.The intestinal microbial disorder was evidently ameliorated by increasing the relative abundance of Clostridium sensu stricto 1,Bifidobacterium,GCA-900066225,Enterorhabdus,and reducing the relative abundance of Lachnospiraceae NK4A136 group.In conclusion,oral administration of B.producta D4 could ameliorate DSS-induced colitis by suppressing inflammatory responses,maintaining the intestinal barrier,inhibiting TLR4/NF-κB pathway,and regulating intestinal microbiota balance.These results are conducive to accelerate the development of B.producta D4 as a functional probiotic for colitis. 展开更多

D-Psicose,as a low-calorie rare sugar,has attracted a lot of attention in recent years for alternating to sucrose.The anti-obesity effect of D-psicose has been extensively confirmed in previous studies,however,the impact of D-psicose on colitis remains vague.Here,we firstly evaluated the effect of the D-psicose prophylactic intervention on dextran sulfate sodium-induced colitis in C57BL/6 mice.The pathological symptoms,inflammatory cytokines levels,gut microbiota composition,short chain fatty acids(SCFAs)production and colonic barrier integrity were comprehensively evaluated.The results confirmed that D-psicose intervention aggravated colitis,characterized by the exacerbation of colon shortening,increase of colonic inflammatory infiltration,and marked exaltation of disease activity indices and IL-6,IL-1βand TNF-αlevels.Further,the dysfunction of gut microbiota was identified in the psicose group.The abundance of pro-inflammatory bacteria Lachnospiraceae_NK4A136_group was significantly up-regulated while the abundance of probiotics Akkermansia and Lactobacillus were significantly down-regulated in the psicose group compared to the model group.Moreover,the production of SCFAs was suppressed in the psicose group,accompanied by a decrease in the level of mucin 2(Muc-2).Collectively,the underlying mechanism of the exacerbation of colitis by D-psicose intervention might be attributed to microbiota dysfunction accompanied by the reduction of SCFAs,which leads to the damage of the mucosal barrier and the intensifi cation of inflammatory invasion. 展开更多

Lactobacillus spp.can be beneficial for the prevention or treatment of ulcerative colitis(UC).In this study,153 participants who followed vegan,omnivorous,or high-meat diet were recruited.Compositional analysis of the Lactobacillus community in feces revealed that Lactobacillus fermentum strains were significantly affected by diet.Administration of mixed L.fermentum strains from vegans significantly improved inflammation compared to that from omnivores and high-meat consumers,as evidenced by a significant reduction in colonic tissue damage,improvement in inflammatory cytokines,enhanced expression of ZO-1,occludin,and claudin-3,and a significant increase in short chain fatty acids concentration.The effect of a single strain of L.fermentum was similar to that of a mixed strains of L.fermentum group.Genomic analysis suggested that L.fermentum strains from the guts of vegans possessed a higher prevalence of genes involved in carbohydrate catabolism than those from the guts of omnivores and high-meat eaters.In particular,the ME2 gene is involved in the biosynthesis of acetate,a compound considered to possess anti-inflammatory properties.In conclusion,this study indicates strain-specific differences in the ability of L.fermentum strains to alleviate UC in mice,influenced by habitual diets。 展开更多

Recent advancements in the treatment landscape of ulcerative colitis(UC)have ushered in a new era of possibilities,particularly with the introduction of Janus kinase(JAK)-signal transducer and activator of transcription inhibitors.These novel agents offer a paradigm shift in UC management by targeting key signaling pathways involved in inflammatory processes.With approved JAK inhibitors(JAKis),such as tofacitinib,filgotinib,and upadacitinib,clinicians now have powerful tools to modulate immune responses and gene expression,potentially revolutionizing the treatment algorithm for UC.Clinical trials have demonstrated the efficacy of JAKis in inducing and maintaining remission,presenting viable options for patients who have failed conventional therapies.Real-world data support the use of JAKis not only as first-line treatments but also in subsequent lines of therapy,particularly in patients with aggressive disease phenotypes or refractory to biologic agents.The rapid onset of action and potency of JAKis have broadened the possibilities in the management strategies of UC,offering timely relief for patients with active disease and facilitating personalized treatment approaches.Despite safety concerns,including cardiovascular risks and infections,ongoing research and post-marketing surveillance will continue to refine our understanding of the risk-benefit profile of JAKis in UC management. 展开更多

This study mainly investigated the regulatory effect of Rosa roxburghii Tratt fruit juice fermented by Lacticaseibacillus paracasei SR10-1(LAB-RRTJ)on modulating gut microbiota in dextran sulfate sodium(DSS)-induced ulcerative colitis in mice.Compared to control group,DSS induction decreased body weight of mice,indexes of Shannon,Simpson,Chao1 and Faith_pd,and increased disease activity index(DAI)and levels of interleukin 1β(IL-1β),IL-6,tumor necrosis factorα(TNF-α)and interferon-γ(IFN-γ);And this induction also led to an increase in Proteobacteria,Verrucomicrobia and Actinobacteria at phylum level,harmful bacterial species richness at genus level,and relative richness of S.sciuri,Desulfovibrio C21_c20,R.gnavus and Akkermansia muciniphila at species level,and a decrease in Firmicutes at phylum level and relative richness of B.acidifaciens in mice.LAB-RRTJ increased body weight of mice with DSS induced ulcerative colitis(UC)and indexes of Shannon,Simpson,Chao1 and Faith_pd,reduced DAI and the content of four infl ammatory factors and improved gut microbiota imbalance in DSS induced UC mice.Besides,the number of operational taxonomic units(OTUs)increased,α-diversity andβ-diversity were restored and similar to those in mice in the control group after LAB-RRTJ treatment.Compared with the positive drug treatment group,LAB-RRTJ has a better effect on regulating gut microbiota diversity in colitis mice.Correlation analysis showed that infl ammatory factors were positively correlated with harmful bacteria and negatively correlated with beneficial bacteria which commonly found in some colitis mice.Taken together,our study demonstrated that LAB-RRTJ could alleviate DSS-induced colitis in mice through the modulation of infl ammatory cytokines and gut microbiota composition. 展开更多

BACKGROUND Congestive ischemic colitis is a rare subtype of ischemic colitis with an unknown pathophysiology.Excluding conservative management,such as fasting,no established treatment exists;therefore,surgical intervention should be considered in some cases if symptoms worsen.Current literature suggests that anti-inflam-matory agents may effectively treat congestive ischemic colitis.CASE SUMMARY We present the case of a 68-year-old female patient who underwent laparoscopic left hemicolectomy for transverse colon cancer 3 years ago.Postoperatively,follow-up included an annual colonoscopy and abdominal computed tomography(CT)at a local clinic.However,progressive erythema and edema of the sigmoid colon were observed 1 year postoperatively.Upon admission to our hospital,she complained of abdominal pain and diarrhea.Abdominal CT showed thickening of the sigmoid colon walls,and colonoscopy revealed erythema,edema,and multiple ulcers with exudate in the sigmoid colon.CT angiography showed engorgement of the sigmoid vasa recta without any vascular abnormalities.The diagnosis was congestive ischemic colitis,and we treated the patient with anti-inflammatory agents.After 2 mo of glucocorticoid therapy(20 mg once daily)and 7 mo of 5-aminosalicylate therapy(1 g twice daily),the ulcers completely healed.She has not experienced any recurrence for 2 years.CONCLUSION Anti-inflammatory therapy,specifically glucocorticoids and 5-aminosalicylate,has demonstrated promising efficacy and introduces potential novel treatment options for congestive ischemic colitis. 展开更多

BACKGROUND Ulcerative colitis(UC)is an inflammatory condition with frequent relapse and recurrence.Evidence suggests the involvement of SLC6A14 in UC pathogenesis,but the central regulator remains unknown.AIM To explore the role of SLC6A14 in UC-associated pyroptosis.METHODS Quantitative real-time polymerase chain reaction(qRT-PCR),immunoblotting,and immunohistochemical were used to assess SLC6A14 in human UC tissues.Lipopolysaccharide(LPS)was used to induce inflammation in FHC and NCM460 cells and model enteritis,and SLC6A14 levels were assessed.Pyroptosis markers were quantified using enzyme-linked immunosorbent assay,Western blotting,and qRT-PCR,and EdU incubation,CCK-8 assays and flow cytometry were used to examine proliferation and apoptosis.Mouse models of UC were used for verification.RESULTS SLC6A14 was increased and correlated with NLRP3 in UC tissues.LPS-induced FHC and NCM460 cells showed increased SLC6A14 levels.Reducing SLC6A14 increased cell proliferation and suppressed apoptosis.Reducing SLC6A14 decreased pyroptosis-associated proteins(ASC,IL-1β,IL-18,NLRP3).NLRP3 overexpression counteracted the effects of sh-SLC6A14 on LPS-induced FHC and NCM460 cell pyroptosis.SLC6A14 improved the mucosa in mice with dextran sulfate sodium-induced colitis.CONCLUSION SLC6A14 promotes UC pyroptosis by regulating NLRP3,suggesting the therapeutic potential of modulating the SLC6A14/NLRP3 axis. 展开更多

In this editorial,we provide commentary on the study by Gong et al.In this original research article,Gong et al employed a bioinformatics approach to investigate the involvement of autophagy in active ulcerative colitis(UC).Through differential gene expression analysis,they identified 58 differentially expressed autophagy-related genes in UC patients compared to healthy controls.Notably,HSPA5,CASP1,SERPINA1,CX3CL1,and BAG3,were found to be upregulated in active UC patients,suggesting their significance as core autophagyrelated targets.Enrichment analysis unveiled associations with crucial signaling pathways and diseases such as middle cerebral artery occlusion and glomerulonephritis.Moreover,immune cell infiltration analysis revealed notable differences in immune cell composition between UC patients and healthy controls.These findings offer valuable insights into the role of autophagy in UC pathogenesis and potential therapeutic targets. 展开更多
