Ali I, Abdo Q, Al-Hihi SM, Shawabkeh A. Association between ulcerative colitis and Helicobacter pylori infection: A case-control study. Heliyon 2022; 8:e08930. [PMID: 35198786 PMCID: PMC8841358 DOI: 10.1016/j.heliyon.2022.e08930] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 11/16/2021] [Accepted: 02/07/2022] [Indexed: 01/08/2023] Open
Abstract
Introduction Ulcerative Colitis (UC), a type of inflammatory bowel disease (IBD), is defined as chronic inflammation of the superficial mucosal layer of the large intestine. In this study, we aimed to investigate the association between Helicobacter pylori (H. pylori) colonization, and UC in Palestine. Methods A total of 35 Palestinian patients of UC and 105 age-matched and gender-matched controls were retrospectively studied for a period of one year. Diagnosis of ulcerative colitis was based on both colonoscopy and biopsy. The presence of H. pylori in the stomach was evaluated by the H. pylori stool antigen test (HpSA). An interview-based data collection form was filled for all patients with UC before starting the test. Results The overall positivity of H. pylori infection in patients with UC was 14.3%, significantly lower than the control group, 41.9% (odds ratios (OR) = 0.23, 95% confidence intervals (CI): 0.083–0.643, P-value = 0.003). Interestingly, the presence of H. pylori showed no correlation with the extension of UC (P-value = 0.44). Moreover, there were no relationships between the presence of H. pylori and age (P-value = 0.97), gender (P-value = 0.26), smoking (P-value = 0.08), and medication regimen (P-value = 0.80). Conclusion The rate of H. pylori infection was significantly lower in patients with UC compared with the control group suggesting a protective role of H. pylori against the occurrence of UC.

Five-Flavor Sophora flavescens Enteric-Coated Capsules for Ulcerative Colitis: A Systematic Review and Meta-Analysis of Randomized Clinical Trials. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:9633048. [PMID: 35069773 PMCID: PMC8769833 DOI: 10.1155/2022/9633048] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Accepted: 11/24/2021] [Indexed: 01/30/2023]
Abstract
Background Ulcerative colitis (UC), a chronic inflammatory bowel disease, is characterized by abdominal pain, diarrhea, and mucopurulent bloody stool. In recent years, the incidence and prevalence of UC have been increasing consistently. Five-flavor Sophora falvescens enteric-coated capsule (FSEC), a licensed Chinese patent medicine, was specifically used to treat UC. This review was aimed to assess the effectiveness and safety of FSEC for the treatment of UC. Methods Six electronic databases were searched from inception to March 2021. Randomized clinical trials (RCTs) comparing FSEC or FSEC plus conventional Western medicine with conventional Western medicine in participants with UC were included. Two authors screened all references, assessed the risk of bias, and extracted data independently. Binary data were presented as risk ratios (RRs) with 95% confidence intervals (CIs) and metric data as mean difference (MD) with 95% CI. The overall certainty of the evidence was assessed by GRADE. Results We included 15 RCTs (1194 participants, 763 in the FSEC group and 431 in the control group). The treatment duration ranged from 42 to 64 days. Twelve trials compared FSEC with conventional Western medicine, and two trials compared FSEC plus conventional medicine with conventional medicine. Another trial compared FSEC plus mesalazine with compound glutamine enteric capsules plus mesalazine. FSEC showed a higher clinical effective rate (improved clinical symptoms, colonoscopy results, and stools) (RR 1.12, 95% CI 1.05 to 1.20; 729 participants; 8 trials; low-quality evidence) as well as the effective rate of traditional Chinese medicine (TCM) syndromes (RR 1.10, 95% CI 1.01 to 1.20; 452 participants; 5 trials; low-quality evidence) compared to mesalazine. There was no significant difference in the adverse events between FSEC and control groups. Conclusions FSEC may show effectiveness in UC treatment compared to conventional medicine, and the use of FSEC may not increase the risk of adverse events. Due to the limited number of clinical trials and low methodological quality of the included trials, our findings must be interpreted with discretion.

Ghahramani S, Tamartash Z, Sayari M, Vahedi H, Karimian F, Heydari S, Bagheri Lankarani K. Risk Factors Affecting 90-day Readmission of Patients with Inflammatory Bowel Disease. Middle East J Dig Dis 2022; 14:34-43. [PMID: 36619729 PMCID: PMC9489331 DOI: 10.34172/mejdd.2022.253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Accepted: 11/01/2021] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND: The rate of hospital readmission is seen as a measure of quality and accountability. Knowing the risk factors that can be changed could reduce the cost burden on patients with inflammatory bowel disease (IBD) and the health system. METHODS: Retrospective analysis was performed on the data extracted from hospital records during a 4-year period. The study setting encompassed three referral hospitals in Tehran and the south of Iran. The primary outcome was hospital readmission of patients with IBD. The factors associated with binary and categorical dependent variables were analyzed using robust logistic regression and multinomial logistic regression, respectively. The significance level was set at P=0.05. RESULTS: 187 patients were admitted during the 4-year study period for an IBD-related reason, among whom 131 patients (70.1%) had ulcerative colitis (UC), and 56 patients (29.9%) had Crohn's disease (CD). Moreover, 29% (55) of the participants had been readmitted at least once during the study period, and seven patients with IBD had been readmitted five or more times during the study period. Corticosteroids (OR=4.55, 95% confidence interval CI: 1.65- 12.55) and chronic pain (OR=6.65, 95% CI: 1.73-25.62) were two factors associated with their readmission within 90 days. For the patients with five or more times of readmissions, Corticosteroids (RRR=5.68), chronic pain (RRR=5.05), length of hospital stay (RRR=0.69), and age (RRR=0.9) could significantly explain the hospital readmissions. CONCLUSION: About one in seven hospitalizations of patients with IBD leads to 30-day readmission. Moreover, younger patients with IBD and shorter length of hospital stay were more likely to be readmitted five or more times during the study period. The use of corticosteroids and the presence of chronic pain were predictors of 90-day readmission. More studies are needed to detect the best management plan for chronic pains.

Exploration of the Potential Mechanisms of Wumei Pill for the Treatment of Ulcerative Colitis by Network Pharmacology. Gastroenterol Res Pract 2022; 2021:4227668. [PMID: 34970312 PMCID: PMC8714398 DOI: 10.1155/2021/4227668] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2021] [Accepted: 11/09/2021] [Indexed: 12/17/2022] Open
Abstract
Background Wumei pill (WMP) has a long history of colitis treatment in China, but the protective mechanisms have not been elucidated. To uncover the potential mechanisms of WMP against ulcerative colitis (UC), the network pharmacology approach was utilized in this study. Methods Public databases were utilized to identify the potential targets of WMP and genes related to UC. Based on the identified overlapping common targets, drug-ingredient-target gene network, Gene Ontology (GO) analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, and protein-protein interaction (PPI) analysis were conducted. Molecular docking was carried out to verify the selected key active ingredients and core targets. Results 129 active ingredients and 622 target genes were obtained. The drug-ingredient-target gene network revealed 52 active ingredients of WMP acting on 73 targets related to UC. GO analysis revealed that biological processes were mainly associated with oxidative stress, such as, reactive oxygen species metabolic processes, response to oxidative stress, cellular response to oxidative stress, response to reactive oxygen species, and regulation of reactive oxygen species metabolic processes. KEGG analysis revealed that the immune- and inflammation-related pathways, tumor-related signaling pathways, and microbial infection-related signaling pathways were the most significant. PPI network identified 13 core target genes. The molecular docking results indicated the formation of stable bonds between the active ingredients and core target genes. Conclusions The approach of network pharmacology reveals the key ingredients, potential core targets, and biological process of WMP in the treatment of UC. The mechanisms of action of WMP involve anti-inflammation, antioxidation, and modulation of immunity, which provides evidence for the therapeutic role of WMP in UC.

Abstract
BACKGROUND Ulcerative colitis (UC) is an inflammatory bowel disease with increasing prevalence worldwide. Current treatment strategies place considerable economic and humanistic burdens on patients. The aim of this study was to determine the socioeconomic burden of UC in adult patients in European countries in a real-world setting. METHODS In this retrospective, cross-sectional and observational pan-European study, patients with moderate or severe UC were assigned to ARM 1 and patients who had moderate or severe UC but achieved mild or remission status 12 months before index date (or clinical consultation date), were assigned to ARM 2. Clinical and medical resource use data were collected via electronic case report forms, and data on non-medical and indirect costs, and health-related quality of life (HRQoL) were collected via patient and public involvement and engagement (PPIE) questionnaires. Per-patient annual total costs per ARM and per country were calculated using the collated resource use in the last 12 months (between the start of the documentation period and patient consultation or index date) and country specific unit costs. Quality of life was described by arm and by country. RESULTS In the physician-reported eCRF population (n = 2966), the mean annual direct medical cost was €4065 in ARM 1 (n = 1835) and €2935 in ARM 2 (n = 1131). In the PPIE population (ARM 1, n = 1001; ARM 2, n = 647), mean annual direct cost was €4526 in ARM 1 and €3057 in ARM 2, mean annual direct non-medical cost was €1162 in ARM 1 and €1002 in ARM 2, mean annual indirect cost was €3098 in ARM 1 and €2309 ARM 2, and mean annual total cost was in €8787 in ARM 1 and €6368 in ARM 2. HRQoL scores showed moderate to high burden of UC in both groups. CONCLUSIONS The cost and HRQoL burden were high in patients in both ARM 1 and ARM 2 indicating unmet needs in the UC active population.

Abstract
BACKGROUND AND AIMS This real-world study assessed the impact of golimumab on health-related quality of life (HRQoL) and other patient-reported outcomes (PROs) in patients with ulcerative colitis over 12 months in Greece. METHODS GO-LIFE was a noninterventional, prospective, multicenter, 12-month study. Patients who had moderately-to-severely active ulcerative colitis were naïve to antitumor necrosis factor (anti-TNFα) therapy and had failed previous conventional therapy. Patients received golimumab as per label. The primary endpoint was patients achieving inflammatory bowel disease questionnaire 32-item (IBDQ-32) remission at 12 months. Secondary endpoints, at 6 and 12 months, included patients achieving IBDQ-32 response; the mean change in the treatment satisfaction questionnaire for medication (TSQM) and the work productivity and activity impairment in ulcerative colitis (WPAI:UC) questionnaires; changes in healthcare utilization; patients achieving clinical response and remission; adherence rates and the percentage of patients who discontinued golimumab. RESULTS IBDQ-32 remission was achieved by 76.9% of patients at 12 months. Mean changes in all TSQM and WPAI:UC domain scores at 12 months were statistically significant. Clinical remission was achieved by 49.4 and 50.6% of patients at 6 and 12 months, and clinical response by 59.3 and 56.8%, respectively. All patients but one (80/81) had high adherence (≥80%) to golimumab treatment over 12 months. Ulcerative colitis-related health care resource utilization was reduced during the follow-up period. CONCLUSIONS In real-world settings, treatment with golimumab resulted in meaningful improvements in HRQoL and other PROs, and in disease activity at 6 and 12 months in patients with moderately-to-severely active ulcerative colitis who were naïve to anti-TNFa therapy.

Efficacy and safety of biologics and small molecule drugs for patients with moderate-to-severe ulcerative colitis: a systematic review and network meta-analysis. Lancet Gastroenterol Hepatol 2021; 7:161-170. [PMID: 34856198 DOI: 10.1016/s2468-1253(21)00377-0] [Citation(s) in RCA: 129] [Impact Index Per Article: 43.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 09/19/2021] [Accepted: 10/01/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND There is a growing armamentarium for the treatment of moderate-to-severe ulcerative colitis. We aimed to compare the relative efficacy and safety of biologics and small molecule drugs for the treatment of patients with moderate-to-severe ulcerative colitis. METHODS In this systematic review and network meta-analysis, we searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials without language restrictions for articles published between Jan 1, 1990, and July 1, 2021. Major congresses' databases from Jan 1, 2018, to July 3, 2021, were reviewed manually. Phase 3, placebo-controlled or head-to-head randomised controlled trials (RCTs) assessing the efficacy and safety of biologics or small molecule drugs as induction or maintenance therapies for patients with moderate-to-severe ulcerative colitis were included. Phase 2 RCTs were excluded because of their small sample sizes and inclusion of doses not further explored in phase 3 RCTs. Summary data from intention-to-treat analyses were extracted from included reports by JSL and PAO. The primary outcome was the induction of clinical remission. A network meta-analysis was done under the frequentist framework, obtaining pairwise odds ratios (ORs) and 95% CIs. The surface under the cumulative ranking (SUCRA) was used to rank the included agents for each outcome. Higher SUCRA scores correlate with better efficacy, whereas lower SUCRA scores correlate with better safety. Maintenance data on efficacy for treat-straight-through and randomised responder trials are also presented. This study is registered with PROSPERO, CRD42021225329. FINDINGS Our search yielded 5904 results, from which 29 studies (four being head-to-head RCTs) fulfilled our inclusion criteria and were included. Of these, 23 studies assessed induction therapy with either a biologic or small molecule drug, comprising 10 061 patients with ulcerative colitis. A risk of bias assessment showed a low risk of bias for most of the included studies. Upadacitinib was significantly superior to all other interventions for the induction of clinical remission (infliximab [OR 2·70, 95% CI 1·18-6·20], adalimumab [4·64, 2·47-8·71], golimumab [3·00, 1·32-6·82], vedolizumab [3·56, 1·84-6·91], ustekinumab [2·92, 1·31-6·51], etrolizumab [4·91, 2·59-9·31], tofacitinib [2·84, 1·28-6·31], filgotinib 100 mg [6·15, 2·98-12·72], filgotinib 200 mg [4·49, 2·18-9·24], and ozanimod (2·70, 1·18-6·20), and ranked highest for the induction of clinical remission (SUCRA 0·996). No differences between active interventions were observed when assessing adverse events and serious adverse events. Vedolizumab ranked lowest for both adverse events (SUCRA 0·184) and serious adverse events (0·139), whereas upadacitinib ranked highest for adverse events (0·843) and ozanimod ranked highest for serious adverse events (0·831). INTERPRETATION Upadacitinib was the best performing agent for the induction of clinical remission (the primary outcome) but the worst performing agent in terms of adverse events in patients with moderate-to-severe ulcerative colitis. Vedolizumab was the best performing agent for safety outcomes. With the paucity of direct comparisons in the published literature, our results might help clinicians to position drugs in treatment algorithms. FUNDING None.

Abstract
BACKGROUND Ulcerative colitis (UC) is a life-long disease characterised by flare ups and periods of remission. This market research sponsored by Janssen-Cilag Ltd was designed to gain an understanding of the impact of UC from the patient's perspective and to establish the main unmet needs associated with it. METHODS The market research was conducted by telephone among 30 patients in the UK with a diagnosis of moderate to severe UC. RESULTS Delayed referral from primary care to secondary care was identified as the key unmet need. Hospital appointments were often unavailable for months and in some cases, it was 6 months before a procedure was performed. Specialists rarely involved the patient in discussions regarding diagnosis and initial treatment. Communications improved when treatment changes became necessary but gaps still existed particularly regarding the continued emotional impact of UC. All patients required treatment changes to regain or maintain control and the response to medications varied between patients. Patients who had transitioned through multiple treatments feared they would run out of options and therefore require surgery. The UC "journey" was highly individualized and patients experienced many emotional "ups and downs". CONCLUSIONS Healthcare bodies should aim to improve earlier referral to secondary care and waiting times for investigation need to be reduced significantly. Patients felt that specialists could support them in understanding their condition by discussing it with them immediately following diagnosis and by involving them in the development of their individual treatment plans. There is a need for more effective and better tolerated medications to expand the armamentarium and thus reduce the need for surgery.

Abstract
Introduction Network pharmacology is in line with the holistic characteristics of TCM and can be used to elucidate the complex network of interactions between disease-specific genes and compounds in TCM herbal medicines. Here, we investigate the pharmacological mechanism of Xiaokui Jiedu decoction (XJD) for the treatment of ulcerative colitis (UC). Methods The Computational Systems Biology Laboratory Platform (TCMSP) database was searched and screened for the active ingredients of all drugs in XJD. The Uniport database was used to retrieve possible gene targets for the therapeutic effects of XJD. GeneCards, PharmGKB, TTD, and OMIM databases were used to retrieve XJD-related gene targets. A herb-compound-protein network and a protein-protein interaction (PPI) network were constructed, and hub genes were screened for Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. Finally, molecular docking was performed to validate the interrelationship between disease target proteins and active drug components. Results A total of 135 XJD potential action targets, 5097 UC-related gene targets, and 103 XJD-UC intersection gene targets were screened. The hub gene targets of XJD that exert therapeutic effects on UC are RB1, MAPK1, TP53, JUN, NR3C1, MAPK3, and ESR1. GO enrichment analysis showed 741 biofunctional enrichments, and KEGG enrichment analysis showed 124 related pathway enrichments. Molecular docking showed that the active components of XJD (β-sitosterol, kaempferol, formononetin, quercetin, and luteolin) showed good binding activities to five of the six hub gene targets. Discussion. The active ingredients of XJD (β-sitosterol, kaempferol, formononetin, quercetin, and luteolin) may regulate the inflammatory and oxidative stress-related pathways of colon cells during the course of UC by binding to the hub gene targets. This may be a potential mechanism of XJD in the treatment of UC.

BACKGROUND The Ulcerative Colitis (UC) Narrative is a global patient and physician survey aimed at identifying the impact of UC and comparing and contrasting perceptions of UC burden and management approaches. METHODS Surveys of patients with UC (self-reported diagnosis; n = 2100) and physicians (n = 1254) were completed across 10 countries by The Harris Poll between August 2017 and February 2018. Questionnaires covered multiple aspects of UC, including diagnosis, treatment, and impact on patient quality of life, in addition to standard demographic information. Descriptive statistics are reported. RESULTS The majority of patients (82%) had moderate to severe UC (based on medication history; those who had only ever taken 5-aminosalicylates were excluded); 67% described their UC as controlled with few to no symptoms. On average, patients experienced 4.3 flares (standard deviation, 7.4) in the past year. Diagnostic delay was on average 2.0 years (standard deviation, 5.4); 42% of patients waited ≥1 year. Most patients (65%) felt that UC controlled their life rather than them controlling their disease. Because of the fear of repercussions, many patients had not disclosed their UC to their employer. Discussion of the emotional impact of UC during routine appointments was less of a priority for physicians, compared with patients. CONCLUSIONS The data from this global survey highlight that patients with UC experience diagnostic delay, poor disease control, and adverse impact on their quality of life. Patients report UC to be a mentally exhausting condition; however, emotional and mental health issues are infrequently discussed at routine appointments.

Identification of Active Compounds and Mechanism of Huangtu Decoction for the Treatment of Ulcerative Colitis by Network Pharmacology Combined with Experimental Verification. DRUG DESIGN DEVELOPMENT AND THERAPY 2021; 15:4125-4140. [PMID: 34616145 PMCID: PMC8487861 DOI: 10.2147/dddt.s328333] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Accepted: 09/17/2021] [Indexed: 01/08/2023]
Abstract
Introduction Huangtu decoction (HTD) has been widely used in the treatment of gastrointestinal bleeding, ulcerative colitis (UC) and gastrointestinal tumors in China, but its active compounds and mechanism are still not clear yet. The present research aimed to identify the active compounds and mechanism of HTD for the treatment of UC. Methods Firstly, the chemical compounds of HTD were qualitatively identified based on Q Exactive Orbitrap LC-MS/MS, and their potential targets were predicted through SwissTargetPrediction. Secondly, the differential expressed genes (DEGs) in colon tissues of UC patients and normal controls were retrieved from the GEO database. Thirdly, the overlapping targets of DEGs and the predicted targets were obtained and subjected to GO and KEGG analysis. Finally, the key targets in the most significantly enriched pathway were verified by in vivo experiment, and the protein and mRNA expressions of matrix metalloproteinase-1 (MMP1), MMP3, MMP7, MMP9 and MMP12 were determined by immunohistochemistry (IHC), Western blotting (WB) and quantitative real-time-PCR (qRT-PCR). Results A total of 47 compounds were identified and 29 overlapping targets were obtained from HTD extract. The most significantly enriched pathway of overlapping targets involved was MMP. HTD improved the pathological damage in colon tissues of DSS-induced UC model and significantly decreased the serum levels of IL-1β and IL-6. The protein and mRNA expressions of MMP1, MMP3 and MMP9 in colon tissues were significantly decreased after HTD treatment. Conclusion HTD treatment can alleviate the colonic inflammation via inhibiting MMPs including MMP1, MMP3 and MMP9.

Abstract
Approximately one in four patients with inflammatory bowel disease are readmitted within 90 days. To reduce hospitalizations, regular follow-up appointments with gastroenterologists are essential. However, the mean wait time for gastroenterology clinic appointments significantly exceeded the target goal of 14 days in North America. Based on literature review, we developed and implemented a new appointment scheduling protocol. The inclusion criteria were adult patients with inflammatory bowel disease who were recently hospitalized or newly referred to a gastroenterology clinic. At weeks 0 and 12, wait times were extrapolated from chart review, and patient satisfaction rates were collected via surveys. Patient demographics and outcome data were examined using descriptive statistics. A total of 16 patients were included. Following the intervention, the mean wait time decreased from 40.4 (SD = 31.9) to 21.9 days (SD = 11.4), but the change was statistically insignificant (p = .408). Poor response rates (47%) limited the interpretation of the patient satisfaction data. Despite the small sample size, our project was the first quality improvement initiative that implemented an evidence-based appointment scheduling protocol among adult patients with inflammatory bowel disease. Further studies are warranted with a larger sample size to better evaluate its efficacy in achieving timely outpatient gastroenterology care.

Abstract
Background Patients diagnosed with inflammatory bowel disease may be treated with biologics, depending on several medical and non-medical factors. This study investigated healthcare costs and production values of patients treated with biologics. Methods This national register study included patients diagnosed with Crohn’s disease (CD) and ulcerative colitis (UC) between 2003 and 2015, identified in the Danish National Patient Register (DNPR). Average annual healthcare costs and production values were compared for patients receiving biologic treatment or not, and for patients initiating biologic treatment within a year after diagnosis or at a later stage. Cost estimates and production values were based on charges, fees and average gross wages. Results Twenty-six point one percent CD patients and ten point seven percent of UC patients were treated with biologics at some point in the study period. Of these, 46.4 and 45.5 % of patients initiated biologic treatment within the first year after diagnosis. CD and UC patients treated with biologics had higher average annual healthcare costs after diagnosis compared to patients not treated with biologics. CD patients receiving biologics early had lower production values both ten years before and eight years after treatment initiation, compared to patients receiving treatment later. UC patients receiving biologics early had lower average annual production values the first year after treatment initiation compared to UC patients receiving treatment later. Conclusions CD and UC patients receiving biologic treatment had higher average annual healthcare costs and lower average annual production values, compared to patients not receiving biologic treatment. The main healthcare costs drivers were outpatient visit costs and admission costs.

Abstract
BACKGROUND Knowledge of the cost of illness of inflammatory bowel disease (IBD) is essential for health policy makers worldwide. AIM To assess the cost of illness of IBD from the societal perspective taking into account time trends and geographical differences. METHODS A systematic review of all population-based studies on cost of illness of IBD published in Embase, Medline, Web of Science and Google Scholar. Methodology of included studies was assessed and costs were adjusted to 2018 US dollars. RESULTS Study methodologies differed considerably, with large differences in perspective, valuation method and population. For prevalent Crohn's disease (CD) cases in the last ten years annual healthcare costs were in Asia $4417 (range $1230-$31 161); Europe $12 439 ($7694-$15 807) and North America $17 495 ($14 454-$20 535). For ulcerative colitis (UC), these were $1606 ($309-$14 572), $7224 ($3228-$9779) and $13 559 ($13 559-$13 559). The main cost driver was medication, the cost of which increased considerably between 1985 and 2018, while outpatient and inpatient costs remained stable. IBD had a negative impact on work productivity. Annual costs of absenteeism for CD and UC were in Asia (with presenteeism) $5638 ($5638-$5638) and $4828 ($4828-$4828); Europe $2660 ($641-$5277) and $2394 ($651-$5992); North America $752 ($307-$1303) and $1443 ($85-$2350). CONCLUSION IBD societal cost of illness is increasing, driven by growing costs of medication, and varies considerably between continents. While biologic therapy was expected to decrease inpatient costs by reducing hospitalisations and surgery, these costs have not declined.

Abstract
Background Huai Hua San (HHS), a famous Traditional Chinese Medicine (TCM) formula, has been widely applied in treating ulcerative colitis (UC). However, the interaction of bioactives from HHS with the targets involved in UC has not been elucidated yet. Aim A network pharmacology-based approach combined with molecular docking and in vitro validation was performed to determine the bioactives, key targets, and potential pharmacological mechanism of HHS against UC. Materials and Methods Bioactives and potential targets of HHS, as well as UC-related targets, were retrieved from public databases. Crucial bioactive ingredients, potential targets, and signaling pathways were acquired through bioinformatics analysis, including protein-protein interaction (PPI), as well as the Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Subsequently, molecular docking was carried out to predict the combination of active compounds with core targets. Lastly, in vitro experiments were conducted to further verify the findings. Results A total of 28 bioactive ingredients of HHS and 421 HHS-UC-related targets were screened. Bioinformatics analysis revealed that quercetin, luteolin, and nobiletin may be potential candidate agents. JUN, TP53, and ESR1 could become potential therapeutic targets. PI3K-AKT signaling pathway might play an important role in HHS against UC. Moreover, molecular docking suggested that quercetin, luteolin, and nobiletin combined well with JUN, TP53, and ESR1, respectively. Cell experiments showed that the most important ingredient of HHS, quercetin, could inhibit the levels of inflammatory factors and phosphorylated c-Jun, as well as PI3K-Akt signaling pathway in LPS-induced RAW264.7 cells, which further confirmed the prediction by network pharmacology strategy and molecular docking. Conclusion Our results comprehensively illustrated the bioactives, potential targets, and molecular mechanism of HHS against UC. It also provided a promising strategy to uncover the scientific basis and therapeutic mechanism of TCM formulae in treating diseases.

Abstract
The role of supplementation with different Bacteroides fragilis (B. fragilis) strains in alleviating ulcerative colitis (UC) is unclear due to the controversial results from animal experiments. In this study, three B. fragilis strains were evaluated for their ability to alleviate dextran sulfate sodium (DSS)-induced UC in C57BL/6J mice. We analyzed the anti-inflammatory effects of different B. fragilis strains and the changes they caused in the intestinal microbiota composition, intestinal epithelial permeability, cytokine concentrations, protein expression of nuclear factor kappa-B (NF-κB) and the underlying specific genes. The results showed that when orally administered, the different B. fragilis strains exerted different effects on the assessed parameters of the mice. The results of real-time quantitative polymerase chain reaction and immunofluorescence staining showed that the supplementation of B. fragilis FSHCM14E1, but not FJSWX11BF, enhanced the expression of the tight-junction proteins ZO-1, occludin and claudin-1. Western blot analysis showed that the anti-inflammatory effects of B. fragilis FSHCM14E1 were related to the NF-κB pathway. Genomic analysis suggested that the anti-inflammatory effects of FSHCM14E1 may be mediated through specific genes associated with defense mechanisms and the secretion of SCFAs. Overall, this study indicates the therapeutic potential of B. fragilis FSHCM14E1 for the prevention of UC.

Abstract
As a chronic inflammatory disease, ulcerative colitis has significant negative impact on the quality of life (QoL) of patients. Since the disease affects many aspects of QoL, comprising multiple domains, treatments that induce and maintain remission can provide benefits beyond hard clinical endpoints. Effective treatment of ulcerative colitis can restore QoL and return it to normal or near normal levels. Biological therapies have shown consistent improvement in the QoL of patients with ulcerative colitis during the induction phase, with benefits that are generally maintained in the long-term. Current medical treatment options broadly comprise aminosalicylates, corticosteroids, thiopurines, and calcineurin inhibitors, as well as biologic therapies. Conventional therapies do not always adequately control disease in a sizeable portion of patients, while anti-TNF antibodies are associated with several issues such as contraindications, intolerance, primary non-response, and loss of response in some patients. JAK inhibitors have been associated with clinical improvements in disease manifestations and long-term improvement in QoL outcomes. However, additional studies are needed to better understand the comparative effects of different treatments on QoL and patient preferences for therapy. Herein, the available evidence is reviewed regarding the impact of various treatments on QoL in patients with moderate to severe ulcerative colitis.

Abstract
BACKGROUND-AIM Intravenously administered biologicals are associated with a huge pressure to Infusion Units and increased cost. We aimed to assess the impact of switching infliximab to golimumab in ulcerative colitis (UC) patients in deep remission. Patients and method: In a prospective, single-centre pilot study UC patients on infliximab mono-therapy for = 2 years, whowere in deep remission, consented to switch to golimumab and were followed for 1 year with clinical assessment, serum and faecal biomarkers, work productivity, satisfaction with treatment and quality of life parameters. Endoscopic remission was assessed by colonoscopy at 1 year. Patients fulfilling the same inclusion criteria, who did not consent to switch to golimumab and continued to receive infliximab mono-therapy, for the same period, served as controls. PATIENTS AND METHODS In a prospective, single-centre pilot study UC patients on infliximab mono-therapy for ≥ 2 years, who were in deep remission, consented to switch to golimumab and were followed for 1 year with clinical assessment, serum and faecal biomarkers, work productivity, satisfaction with treatment and quality of life parameters. Endoscopic remission was assessed by colonoscopy at 1 year. Patients fulfilling the same inclusion criteria, who did not consent to switch to golimumab and continued to receive infliximab mono-therapy, for the same period, served as controls. RESULTS Between October 2015 and October 2017, 20 patients were recruited; however one patient stopped therapy because of pregnancy. All 19 patients who were switched to golimumab were still in clinical, biomarker and endoscopic remission at 1 year and maintained excellent quality of life without any complications. In the control group, 18 of 19 patients were also in deep remission, since only one patient had a flare which was managed with IFX dose intensification. During a median 3 years extension treatment with golimumab only 2 patients experienced a flare of colitis. CONCLUSIONS This pilot study indicates that switching from in-fliximab to golimumab in UC patients in deep remission does not compromise treatment effectiveness or the course of disease; golimumab offers a valid alternative to intravenous infliximab infusions during the COVID-19 pandemic.

Abstract
Objectives: Because only one head-to-head randomized trial of biologics for moderate-to-severe UC has been performed, indirect treatment comparisons remain important. This systematic review and network meta-analysis examined efficacy and safety of biologics and tofacitinib for moderate-to-severe UC, using vedolizumab as reference.Methods: Relevant studies (N = 19) of vedolizumab, adalimumab, infliximab, golimumab, ustekinumab, and tofacitinib were identified. Study design differences were addressed by assessing efficacy outcomes conditional on response at maintenance initiation. Primary analysis used fixed-effect models to estimate odds ratios for efficacy and safety endpoints.Results: Compared with vedolizumab 300 mg, adalimumab 160/80 mg was associated with less clinical remission (odds ratio, 0.69 [95% credible interval, 0.54-0.88]), and infliximab 5 mg/kg was associated with more clinical remission (1.67 [1.16-2.42]) and response (1.63 [1.15-2.30]). Adalimumab 40 mg, golimumab 50 mg, and ustekinumab 90 mg Q12W had significantly lower clinical remission rates during maintenance (0.62 [0.45-0.86], 0.55 [0.32-0.95], and 0.59 [0.35-0.99]) versus vedolizumab 300 mg Q8W. Response results were similar. Tofacitinib 10 mg had the highest maintenance treatment efficacy estimates and highest infection risk.Conclusion: Network meta-analysis and novel integrated benefit-risk analysis suggest a potentially favorable efficacy-safety balance for vedolizumab vs adalimumab and other advanced UC therapies.

Abstract
BACKGROUND Inflammatory bowel disease (IBD), consisting of Crohn's disease and ulcerative colitis, can be a lifelong burden generating high costs to an economic system. Data regarding the cost of workplace presenteeism and absenteeism in workers with IBD are limited. Our objective was to assess these costs in employed adults. METHODS A structured questionnaire, hospital records and national registers were combined to assess the economic costs involved with workplace presenteeism and absenteeism in employed patients. Our final sample comprised 320 IBD patients. The costs were calculated as productivity-loss costs by using a Human Capital Approach. RESULTS Due to IBD, the mean annual economic costs of workplace presenteeism were €643.90/patient, and mean annual absenteeism costs were €740.90/patient. Women had higher costs (€955/patient/year) from absenteeism compared to men (€531/patient/year) especially when working blue-collar jobs. These findings were also evident in presenteeism. CD and UC patients had similar total costs due to presenteeism and absenteeism. The use of biologics did not have a major impact on these costs. CONCLUSION IBD patients had moderate economic costs from workplace presenteeism and absenteeism. Interestingly, women, working blue-collar jobs, had higher costs than men.

Abstract
Inflammatory bowel disease is characterized by chronic inflammation of the gastrointestinal tract and is associated with high risks for complications, surgeries, and frequent hospitalizations. Approximately one in four inflammatory bowel disease patients are readmitted to the hospital within 90 days of discharge in the United States. Although existing literature showed a timely clinic appointment with gastroenterologists is a protective factor for disease flare-ups and hospitalizations, the follow-up appointments were found to be either lacking or significantly delayed. Further, evidence-based guidelines in timely inflammatory bowel disease care are lacking. Thus, this integrative review examined current literature to identify effective strategies for achieving timely clinic appointments with gastroenterologists in inflammatory bowel disease. A comprehensive search of three electronic databases (PubMed, Embase, and Cumulative Index of Nursing and Allied Health Literature [CINAHL] Plus) was conducted from January 2009 to September 2019 using the key terms: inflammatory bowel disease, ulcerative colitis, Crohn's disease, appointments, and time to appointment. Nine articles met the inclusion criteria. The main interventions for timely inflammatory bowel disease care included (i) clinic-wide scheduling protocols, (ii) a dedicated healthcare team, (iii) efficient referral process, (iv) appointment management based on disease acuity and severity, and (v) addressing shortage of inflammatory bowel disease clinicians. Further research is needed to quantify the magnitude of timely inflammatory bowel disease care interventions with controls and evaluate the efficacy with a head-to-head trial. Through timely referrals, evaluations, and treatments, these quality improvement endeavors will ultimately improve quality of care and contribute to reduction in preventable hospitalizations and associated healthcare costs from delayed outpatient inflammatory bowel disease care.

Abstract
BACKGROUND Ulcerative colitis (UC) is a chronic inflammatory bowel disease with recurrent episodes of debilitating symptoms negatively affecting work productivity and health-related quality of life (HRQoL). The use of biologics in UC treatment improves work and HRQoL but prospective long-term data concerning the treatment with TNFα inhibitor golimumab in UC patients are still rare. Therefore, our study aimed to evaluate the change in work productivity, capacity for daily activities and HRQoL in UC patients treated with golimumab in Germany. METHODS Using the Work Productivity and Activity Impairment questionnaire, the change in work productivity and in capacity for daily activities after 3 months and over the whole observational period of 24 months were assessed (both primary endpoints). Disease-specific and health-related quality of life (QoL) were analyzed with the Inflammatory Bowel Disease Questionnaire (IBDQ), the Short-Form 12 Health Survey Questionnaire (SF-12), and the Partial Mayo Score (secondary endpoints). Further, disease-related hospitalization rates were assessed. RESULTS This prospective non-interventional study included 286 patients. Thereof, 212 patients were employed at baseline (modified intention to treat analysis set employed at baseline, mITTe). 61.3% of the mITTe patients had moderate and 17.0% had severe UC. Three months after initiation of golimumab therapy, total work productivity impairment (TWPI) score and activity impairment score improved significantly from baseline with a mean change of - 17.3% (p < 0.0001) and - 14.4% (p < 0.0001), respectively. Results persisted over 24 months (mean change TWPI score: - 24.5%, mean change activity impairment score: - 30.0%). Disease- and health-related QoL also improved significantly under golimumab treatment as indicated by increased IBDQ [mean change: 28.0 (SD: ± 36.1, month 3), 42.1 (SD: ± 39.5, month 24)] and SF-12 scores [PCS-12: 45.9 (SD: ± 8.5), MCS-12: 4.9 (SD: ± 10.6, month 3), PCS-12: 5.9 (SD: ± 9.0), MCS-12: 6.4 (SD: ± 11.1, month 24)]. Disease-related hospitalization rate decreased from 16.0% (BL) to 4.3% at month 24 and the mean number of missed working days due to UC decreased from 8.2 (SD: 17.6, BL) to 0.7 (SD: 2.1) after golimumab induction. CONCLUSIONS Golimumab leads to notable long-term improvements in work productivity, daily activity, HRQoL, and disease-related hospitalization rates in patients with moderate to severe UC.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of tofacitinib versus other treatment options currently available for the management of adult patients with moderate-to-severe ulcerative colitis, who have had an inadequate response, loss of response, or were intolerant to conventional therapy or a biologic agent, in Greece. METHODS A Markov model was adapted for projecting lifetime costs and outcomes, for a cohort of patients with moderate-to-severe ulcerative colitis from a Greek payer perspective. Patients entered the model in the active ulcerative colitis state and transitioned to a remission or response state or they underwent colectomy. Following an initial 8-week induction treatment period, patients received maintenance therapy until loss of response. Nonresponders could switch to up to two subsequent biologic lines. Clinical efficacy, adverse event rates and utilities derived from OCTAVE trials and a network-meta-analysis (NMA), while adverse event-related disutilities were obtained from the literature. Information on treatment pathways and resource use was provided by an advisory board due to a lack of local data. Unit costs derived from official national sources (€, 2018). RESULTS Over a life-time horizon, treating moderate-to-severe active ulcerative colitis with tofacitinib resulted in additional quality-adjusted life-years (QALYs) and lower total costs compared to vedolizumab (0.018; €6408), infliximab (biosimilar) (0.009; €3031), golimumab (0.042; €1988) and infliximab (originator) (0.009; €6724). Hence, tofacitinib was estimated to be dominant over all comparators. CONCLUSION The results of the analysis suggest that in the Greek setting, tofacitinib could be considered a cost-effective (dominant) treatment option for the treatment of patients with moderate-to-severe active ulcerative colitis.

Abstract
BACKGROUND To evaluate the cost-effectiveness of tofacitinib in comparison to vedolizumab for the treatment of moderate-to-severe ulcerative colitis (UC) after failure or intolerance to conventional therapy (bio-naive) or first-line biologic treatment (bio-experienced), from the Spanish National Health System (NHS) perspective. METHODS A lifetime Markov model with eight-week cycles was developed including five health states: remission, response, active UC, remission after surgery, and death. Response and remission probabilities (for induction and maintenance periods) were obtained from a multinomial network meta-analysis. Drug acquisition - biosimilar prices included - (ex-factory price with mandatory deductions), administration, surgery, patient management, and adverse event management costs (€, year 2019) were considered. A 3% discount rate (cost/outcomes) was applied. Probabilistic and deterministic sensitivity analyses (PSA) were conducted. RESULTS Tofacitinib was dominant versus vedolizumab (both in bio-naive and bio-experienced patients) entailing total cost savings of €23,816 (bio-naïve) and €11,438 (bio-experienced). Differences in quality-adjusted life-year (QALY) were smaller than 0.1 for both populations. PSA results showed that tofacitinib has a high probability of being cost-effective (bio-naïve: 82.5%; bio-experienced: 90.6%) versus vedolizumab. CONCLUSIONS From the Spanish NHS perspective, tofacitinib could be a dominant treatment (less costly and more effective) in comparison to vedolizumab, with relevant cost savings and similar QALY gains.

Abstract
AIM The aim of the present study was to investigate the anti-inflammatory response mediated of the M1 muscarinic acetylcholine receptor (mAChR) during experimental colitis. MATERIAL AND METHODS After the induction of 6% acetic acid colitis, mice were treated with McN-A-343 0.5, 1.0, and 1.5 mg/kg or dexamethasone (DEXA, 2.0 mg/kg) or pirenzepine (PIR, 10 mg/kg; M1 mAChR antagonist). Colonic inflammation was assessed by macroscopic and microscopic lesion scores, colonic wet weight, myeloperoxidase (MPO) activity, interleukin-1 beta (IL1-β) levels and tumor necrosis factor alpha (TNF-α), glutathione (GSH), malondialdehyde (MDA) and nitrate and nitrite (NO3/NO2), mRNA expression of IKKα, nuclear factor kappa beta (NF-kB) and cyclooxygenase-2 (COX-2), as well protein expression of NF-kB and COX-2. RESULTS Treatment with McN-A-343 at a concentration of 1.5 mg/kg showed a significant reduction in intestinal damage as well as a decrease in wet weight, MPO activity, pro-inflammatory cytokine concentration, markers of oxidative stress and expression of inflammatory mediators. The action of the M1 agonist by the administration of pirenzepine, which promoted the blocking of the mAChR M1-mediated anti-inflammatory response, has also been proven. CONCLUSION The results suggest that peripheral colonic M1 mAChR is involved in reversing the pro-inflammatory effect of experimentally induced colitis, which may represent a promising therapeutic alternative for patients with ulcerative colitis.

Abstract
Background Recent studies have shown that the gut microbiota is closely related to the pathogenesis of Inflammatory Bowel Disease (IBD), but the causal nature is largely unknown. The purpose of this study was to assess the causal relationship between intestinal bacteria and IBD and to identify specific pathogenic bacterial taxa via the Mendelian randomization (MR) analysis. Materials and Methods MR analysis was performed on genome-wide association study (GWAS) summary statistics of gut microbiota and IBD. Specifically, the TwinsUK microbiota GWAS (N = 1,126 twin pairs) was used as exposure. The UK inflammatory bowel disease (UKIBD) and the Understanding Social Program (USP) study GWAS (N = 48,328) was used as discovery outcome, and the British IBD study (N = 35,289) was used as replication outcome. SNPs associated with bacteria abundance at the suggestive significance level (α = 1.0 × 10-5) were used as instrumental variables. Bacteria were grouped into families and genera. Results In the discovery sample, a total of 30 features were available for analysis, including 15 families and 15 genera. Three features were nominally significant, including one family (Verrucomicrobiaceae, 2 IVs, beta = -0.04, p = 0.05) and two genera (Akkermansia, 2 IVs, beta = 0.04, p = 0.05; Dorea, 2 IVs, beta = -0.07, p = 0.04). All of them were successfully replicated in the replication sample (Verrucomicrobiaceae and Akkermansia P replication = 0.02, Dorea P replication = 0.01) with consistent effect direction. Conclusion We identified specific pathogenic bacteria features that were causally associated with the risk of IBD, thus offering new insights into the prevention and diagnosis of IBD.

Abstract
BACKGROUND Functional Abdominal Pain Disorders (FAPDs) present a considerable burden to paediatric patients, impacting quality of life, school attendance and causing higher rates of anxiety and depression disorders. There are no international guidelines for the management of this condition. A previous Cochrane Review in 2011 found no evidence to support the use of antidepressants in this context. OBJECTIVES To evaluate the current evidence for the efficacy and safety of antidepressants for FAPDs in children and adolescents. SEARCH METHODS In this updated review, we searched the Cochrane Library, PubMed, MEDLINE, Embase, PsycINFO and two clinical trial registers from inception until 03 February 2020. We also updated our search of databases of ongoing research, reference lists and 'grey literature' from inception to 03 February 2020. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing antidepressants to placebo, to no treatment or to any other intervention, in children aged 4 to 18 years with a FAPD diagnosis as per the Rome or any other defined criteria (as defined by the authors). The primary outcomes of interest included treatment success (as defined by the authors), pain severity, pain frequency and withdrawal due to adverse events. DATA COLLECTION AND ANALYSIS Two review authors checked all citations independently, resolving disagreement with a third-party arbiter. We reviewed all potential studies in full text, and once again made independent decisions, with disagreements resolved by consensus. We conducted data extraction and 'Risk of bias' assessments independently, following Cochrane methods. Where homogeneous data were available, we performed meta-analysis using a random-effects model. We conducted GRADE analysis. MAIN RESULTS We found one new study in this updated search, making a total of three trials (223 participants) eligible for inclusion: two using amitriptyline (AMI) and one using citalopram. For the primary outcome of treatment success, two studies used reports of success on a symptom-based Likert scale, with either a two-point reduction or the two lowest levels defined as success. The third study defined success as a 15% improvement in quality of life (QOL) ratings scales. Therefore, meta-analysis did not include this final study due to the heterogeneity of the outcome measure. There is low-certainty evidence that there may be no difference when antidepressants are compared with placebo (risk ratio (RR) 1.17, 95% confidence interval (CI) 0.87 to 1.56; 2 studies, 205 participants; I2 = 0%). We downgraded the evidence for significant imprecision due to extremely sparse data (see Summary of findings table 1). The third study reported that participants receiving antidepressants were significantly more likely than those receiving placebo to experience at least a 15% improvement in overall QOL score at 10 and 13 weeks (P = 0.007 and P = 0.002, respectively (absolute figures were not given)). The analysis found no difference in withdrawals due to adverse events between antidepressants and placebo: RR 3.17 (95% CI 0.65 to 15.33), with very low certainty due to high risk of bias in studies and imprecision due to low event and participant numbers. Sensitivity analysis using a fixed-effect model and analysing just for AMI found no change in this result. Due to heterogeneous and limited reporting, no further meta-analysis was possible. AUTHORS' CONCLUSIONS There may be no difference between antidepressants and placebo for treatment success of FAPDs in childhood. There may be no difference in withdrawals due to adverse events, but this is also of low certainty. There is currently no evidence to support clinical decision making regarding the use of these medications. Further studies must consider sample size, homogenous and relevant outcome measures and longer follow up.

Abstract
Inflammatory Bowel Disease (IBD) is an umbrella term used to describe disorders that involve Crohn's disease (CD), ulcerative colitis (UC) and pouchitis. The disease occurrence is more prevalent in the working group population which not only hampers the well being of an individual but also has negative economical impact on society. The current drug regime used therapy is very costly owing to the chronic nature of the disease leading to several side effects. The condition gets more aggravated due to the lower concentration of drug at the desired site. Therefore, in the present scenario, a therapy is needed which can maximize efficacy, adhere to quality of life, minimize toxicity and doses, be helpful in maintaining and stimulating physical growth of mucosa with minimum disease complications. In this aspect, nanotechnology intervention is one promising field as it can act as a carrier to reduce toxicity, doses and frequency which in turn help in faster recovery. Moreover, nanomedicine and nanodiagnostic techniques will further open a new window for treatment in understanding pathogenesis along with better diagnosis which is poorly understood till now. Therefore the present review is more focused on recent advancements in IBD in the application of nanotechnology.

Abstract
Gastrointestinal inflammation is a hallmark of highly prevalent disorders, including cancer treatment-induced mucositis and ulcerative colitis. These disorders cause debilitating symptoms, have a significant impact on quality of life, and are poorly managed. The activation of toll-like receptor 4 (TLR4) has been proposed to have a major influence on the inflammatory signalling pathways of the intestinal tract. Inhibition of TLR4 has been postulated as an effective way to treat intestinal inflammation. However, there are a limited number of studies looking into the potential of TLR4 antagonism as a therapeutic approach for intestinal inflammation. This review surveyed available literature and reported on the in vitro, ex vivo and in vivo effects of TLR4 antagonism on different models of intestinal inflammation. Of the studies reviewed, evidence suggests that there is indeed potential for TLR4 antagonists to treat inflammation, although only a limited number of studies have investigated treating intestinal inflammation with TLR4 antagonists directly. These results warrant further research into the effect of TLR4 antagonists in the intestinal tract.

Abstract
Introduction Infliximab (IFX) therapy is efficacious for inducing and maintaining symptomatic remission in patients with Crohn's disease (CD), but whether this benefit results in reduced hospitalization rates and therefore may improve patients' quality of life in an economically sensible way is conflicting so far. Methods We conducted a noninterventional, multicenter, open-label, prospective study to evaluate the effect of originator IFX treatment on patient-reported outcomes and disease-related hospitalizations in adult CD patients in Germany treated for the first time with IFX according to label. Results Two hundred and ninety-four patients were included in the study. We observed a statistically significant reduction in the number of CD-related hospitalizations from the year before baseline (mean 1.00 per patient, SD ± 0.93) to the mean value of the 1st (0.62, SD ± 0.95) and 2nd year (0.32, SD ± 0.75) of the observation period (p < 0.0001). After 3 months of IFX therapy, work productivity and activity increased by an average of 12.6 and 17.1%, respectively. Patient's clinical outcome was markedly improved as the total CD activity index (CDAI) sum score continuously decreased from baseline to month 24 and the mean score of the total inflammatory bowel disease questionnaire (IBDQ) changed substantially from 141 at baseline to 172 after 24 months of IFX treatment. Additionally, the number of work incapacity days declined. Recently, no new safety issues of IFX have been identified. Conclusion In this large, prospective, multicenter study on disease-related hospitalization rates, work productivity, capacity for daily activities, and HRQoL in patients with CD, IFX significantly reduces their hospitalization rates and improves work productivity, daily activity, and quality of life over 24 months.

Abstract
Five biologics are approved for the treatment of ulcerative colitis (UC): infliximab, adalimumab, golimumab, vedolizumab, and ustekinumab. These drugs have varying levels of efficacy and are recommended as first-line treatment of moderate to severe UC. There has been only 1 head-to-head trial comparing the efficacy of the biologics, adalimumab and vedolizumab, which has important implications for management. Therapeutic drug monitoring of biologics, especially anti-TNF alpha agents, may improve the long-term efficacy of these agents. The future of treatment may include personalization of medications, based on patient-specific and disease-specific characteristics as well as biomarkers, along with appropriate therapeutic drug monitoring.

Abstract
Ulcerative colitis (UC) is a complex chronic, immune-mediated inflammatory disorder of the colon. Factors associated with increased risk of UC include diet, particularly Western diet influences in newly industrialized nations, medications, and lifestyle factors that may influence the host's microbiome or immune response to antigens. Although much evidence identifying potential genetic and host-related factors is currently available, there are still many unanswered questions. As the global UC incidence and prevalence continues to increase, there are multiple opportunities for continued investigation to clarify our understanding of UC, identify potential predictors of disease severity, response to therapy, and novel therapeutic targets.

Abstract
INTRODUCTION The risk of colorectal cancer (CRC) in patients with inflammatory bowel diseases (IBD) is higher compared to the general population and it is related to the type, severity, duration, and extension of the disease. AREAS COVERED This review aims to highlight current evidence from the literature supporting the role of endoscopic surveillance of CRC in patients with IBD. EXPERT OPINION Even in the absence of randomized controlled trials (RCTs), evidence from the literature supports the effectiveness of endoscopic surveillance in reducing IBD-related CRC incidence and mortality. As a consequence, current guidelines recommend colonoscopy 8-10 years after disease or symptom onset in all patients with ulcerative colitis (UC) and Crohn's disease (CD) involving at least one-third of the colon and agree on the necessity of annual surveillance in high-risk patients. Nevertheless, an overall agreement on the optimal intervals for surveillance of low-intermediate risk patients is absent and 2-5 year intervals have been proposed. In the near future, further studies are needed to assess the most effective intervals and tailor the surveillance based on the personal risk profile. Additionally, further efforts should be made to evaluate the role of noninvasive tests as primary screening, thus avoiding unnecessary colonoscopies.

Abstract
INTRODUCTION The prevalence of inflammatory bowel disease (IBD) in Germany is rising. Due to a disease onset at a young age, direct and indirect costs are important. The aim of the present study is to provide a comprehensive presentation of existing healthcare costs for these diseases in Germany and to compare them by inflation adjustments for 2018. MATERIAL AND METHODS Performing a systematic literature search, monetary costs were extracted from German and English literature. Quality and relevance of the studies were assessed with a checklist. RESULTS The average outpatient cost for inflammatory bowel disease amounts between 18 and 87 Euro/pat/30 days, the average inpatient cost was between 1026 and 9083 Euro/case. Depending on the type of calculation, biologicals cause different amounts of cost. Few data are available for direct medical 82 and 618 Euro/pat/30 days, direct non-medical 63 and 84 Euro/pat/30 days and indirect costs 463 and 3493 Euro/pat/30 days. The total costs are about 533 Euro/pat/30 days, related to one year 6485 Euro/pat. CONCLUSION For the first time, it is possible to compare existing medical costs for IBD in Germany. Current studies feature very heterogeneous methods and study populations of IBD. Depending on the collective, the total costs are up to 6485 Euro/patient/year.

Abstract
Background: The regulatory network of ulcerative colitis (UC)-associated miRNAs is not fully understood. In this study, we aim to investigate the global profile and regulatory network of UC associated miRNAs in the context of dextran sulfate sodium (DSS). Methods: UC was induced in C57BL mice using DSS. Differentially expressed miRNAs were screened by RNA sequencing and subjected to the Kyoto Encyclopedia of Genes and Genomes Pathway enrichment analysis. RT-qPCR was used to verify the differential expression of miRNAs and candidate target mRNA. Luciferase reporter vector bearing a miRNA binding site was constructed to verify the binding site of the miRNA on mRNA. Results:A total of 95 miRNAs (31 were up-regulated and 64 were down regulated) differentially expressed in the colonic tissues of the UC mice. Among the differentially expressed miRNAs, IL-25 pathway genes were enriched. Subsequent RT-qPCR confirmed a decreased expression of IL-25 and a significant up regulation of IL-25 target miRNAs including mmu-miR-135b-5p, mmu-miR-7239-5p and mmu-miR-691 in UC mice. Conclusion: Using the luciferase assay, we verified the biding sites of mmu-miR-135b-5p and mmu-miR-691 to the IL-25 3ʹUTR. In conclusion, mmu-miR-135b-5p:IL-25 and mmu-miR-691:IL-25 interactions are important pathways that may exert a protective role in UC.

Abstract
Inflammatory bowel diseases are chronic diseases that develop on the genetic background. They are characterized by an idiopathic, chronic course and periods of activation and remission. However, genetic and environmental factors are thought to play a role in its pathogenesis. Significant improvements in treatment strategies have been witnessed. Depending on the severity of the disease, mesalamine, immunosuppressants, anti-TNF, anti-integrin, Janus kinase inhibitors, and thiopurines can be used for treatment. However, these treatments have side effects such as headache, dizziness, nausea, loss of appetite, hair loss, gas, vomiting, rash, fever, and decreased white blood cell count. The search for treatment that may be a safer alternative, immunomodulatory, and immunosuppressive therapy has gained importance nowadays. Herbal medicine is preferred to treat a wide range of acute and chronic gastrointestinal diseases, including ulcerative colitis. Preclinical and clinical studies show that plants are promising in terms of their use in treating pathological conditions. The effectiveness of plants in treating ulcerative colitis has been determined. However, more studies are needed to explore the long-term effects of these herbal medicines. The present review presents information on medicinal plants and phytochemicals reported for use or potential of application in ulcerative colitis, a type of inflammatory bowel diseases.

Abstract
BACKGROUND Inflammatory bowel diseases (IBD) are costly, chronic illnesses. Key cost-drivers of IBD health care expenditures include pharmaceuticals and unplanned care, but evolving treatment approaches have shifted these factors. We aimed to assess changes in cost of care, determine shifts in IBD cost-drivers, and examine differences by socioeconomic and insurance status over time. METHODS The Medical Expenditure Panel Survey (MEPS), a nationally representative database that collects data on health care utilization and expenditures from a nationally representative sample since 1998, was utilized. Adult subjects with IBD were identified by ICD-9 codes. To determine changes in per-patient costs or cost-drivers unique to IBD, a control population of rheumatoid arthritis (RA) subjects was generated and matched in 1:1 case to control. Total annual health care expenditures were obtained and categorized as outpatient, inpatient, emergency, or pharmacy related. Temporal cohorts from 1998 to 2015 were created to assess change over time. Per-patient expenditures were compared by disease state and temporal cohort using weighted generalized linear models. RESULTS A total of 641 IBD subjects were identified and matched to 641 RA individuals. From 1998 to 2015, median total annual health care expenditures nearly doubled (adjusted estimate 2.20; 95% CI, 1.6-3.0) and were 36% higher in IBD compared with RA. In IBD, pharmacy expenses increased 7% to become the largest cost-driver (44% total expenditures). Concurrently, inpatient spending in IBD decreased by 40%. There were no significant differences in the rate of change of cost-drivers in IBD compared with RA. CONCLUSIONS Per-patient health care costs for chronic inflammatory conditions have nearly doubled over the last 20 years. Increases in pharmaceutical spending in IBD may be accompanied by reduction in inpatient care. Additional studies are needed to explore patient-, disease-, system-, and industry-level cost mitigation strategies.

Abstract
The incidence and prevalence of ulcerative colitis (UC) has been reported to be rising in newly industrialised regions, such as Latin America. Here, we review data from published studies reporting demographics and clinical aspects of UC in Latin America to further understand epidemiology and disease burden. The incidence and prevalence of UC in Latin America varied between regions and studies, ranging between 0.04 to 8.00/100,000 and 0.23 to 76.1/100,000, respectively, and generally increased over the period from 1986 to 2015. The majority of patients with UC were female (53.6-72.6%) and urban residents (77.8-97.4%). Extraintestinal manifestations were reported in approximately 26-89.4% of patients. Use of biologic therapies was generally low (0.8-16.2%), with the exception of Mato Grosso do Sul, Brazil, with a greater proportion of patients tending to receive 5-aminosalicylates, immunosuppressants or corticosteroids; colectomy rates varied between studies (1.5-22%). A high proportion of patients had moderate to severe UC (45.9-73.0%) and, in 11 of 19 studies, the greatest proportion of patients had extensive disease (pancolitis). Colorectal cancer (0-1.7%) and mortality rates (0-7.6%) were low. This evaluation of published studies may influence therapeutic approaches and the development of strategies to improve healthcare access and patient outcomes, although further high-quality studies are required in patients with UC in Latin America.

BACKGROUND The introduction of biologics has revolutionized the management of the chronic inflammatory bowel disease, ulcerative colitis (UC), with many patients experiencing significant improvements not only in their symptoms but in other outcomes relevant to individuals and society as a whole. In Germany, there are no prospective data > 3 mo that assess the work productivity, daily activities and quality of life (QoL) of patients with moderate-to-severe UC treated with golimumab.
AIM To assess change in work productivity, capacity for daily activities and QoL in UC patients treated with golimumab in Germany.
METHODS The validated Work Productivity Activity Impairment (WPAI) Questionnaire was used to analyze the change in work productivity, the capacity for daily activities after three months (primary endpoint) and disease specific and health related QoL (HRQoL) up to 1 year (secondary endpoints). The changes in work productivity and activity impairment were evaluated every three months until month twelve compared to baseline. Disease-specific and health-related QoL were assessed with the inflammatory bowel disease questionnaire and with the short-form 12 health survey questionnaire (SF-12).
RESULTS This prospective non-interventional study included 287 patients. The analysis population was comprised of 282 patients who had completed at least two visits. At baseline, 61% of patients had moderate UC and 18% had severe UC. Furthermore, 75% of patients worked full-time or part-time at baseline. A total of 212 patients who were employed at the start of the study (employed population) were evaluated for the primary endpoint. Golimumab significantly reduced all WPAI sub-scores compared to baseline after three, six, nine and twelve months after the start of treatment (P < 0.0001). In addition, disease-specific QoL and HRQoL, as measured by the SF-12 questionnaire, improved significantly with golimumab at all evaluation times (P < 0.0001 in each case vs baseline).
CONCLUSION Treatment of moderate-to-severe UC with golimumab leads to significant improvements in patient’s work productivity, daily activity and QoL over twelve months.

Abstract
Ulcerative colitis has a significant impact on the quality of life for the patients, and can substantially increase the risk of colon cancer in patients suffering long-term. Conventional treatments provide only modest relief paired with a high risk of side effects, while complementary and alternative medicines can offer safe and effective options. Over the past decade, we have shown that both American ginseng and its hexane fraction (HAG) have anti-oxidant and anti-inflammatory properties that can suppress mouse colitis and prevent colitis-associated colon cancer. With the goal of isolating a single active compound, we further fractionated HAG, and found the most abundant molecule in this fraction was the polyacetylene, panaxynol (PA). After isolating and characterizing PA, we tested the efficacy of PA in the treatment and prevention of colitis in mice and studied the mechanism of action. We demonstrate here that PA effectively treats colitis in a Dextran Sulfate Sodium mouse model by targeting macrophages for DNA damage and apoptosis. This study provides additional mechanistic evidence that American ginseng can be used for conventional treatment of colitis and other diseases associated with macrophage dysfunction.

Abstract
A treat-to-target strategy with close monitoring of intestinal inflammation is recommended in inflammatory bowel disease (IBD). Ileocolonoscopy remains the gold standard for assessing disease activity in IBD but is a relatively invasive procedure and is impossible to repeat in the context of tight monitoring strategies. In addition to biomarkers, cross-sectional imaging increasingly is used in these patients. Computed tomography is limited by the use of radiation, while the use of magnetic resonance enterography (MRE) is limited by its cost and access. There is growing interest in bowel ultrasound that represents a cost-effective, noninvasive, and well-tolerated modality in clinical practice, but it is operator dependent. Compared with ileocolonoscopy and MRE, bowel US has been shown to have the same level of accuracy in assessing and monitoring disease activity for both CD and UC and thus can be considered a point-of-care test. Diffusion-weighted imaging (DWI) is a MR imaging technique that increasingly is used in both IBD and non-IBD conditions and has been shown to be a valuable and accurate tool for assessing and monitoring IBD activity. Compared with conventional MRE, DWI is quicker, less time consuming, may not require intravenous contrast agent, fasting, bowel cleansing, oral preparation, or rectal preparation. This review discusses the role of these cross-sectional imaging techniques for the management of patients with IBD. In the near future, the value of DWI and ultrasound in assessing IBD will require further investigation in the era of transmural healing in CD and complete mucosal healing, including histologic remission, in ulcerative colitis.

Abstract
Introduction: Ulcerative colitis (UC) is a chronic idiopathic autoimmune inflammatory disorder, primarily affecting the gastrointestinal system. There are many patients affected that do not respond well to therapy and many others to which there is a loss of efficacy every year. The proportion of patients who have already experienced anti-TNF therapy is constantly increasing, making the development of new drugs with alternative mechanisms of action an important need for the treatment of UC.Areas covered: This review aims on emerging drugs in the treatment of UC and reviews data on their efficacy and safety.Expert opinion: UC, for many years, comparatively to CD, received little attention for several possible reasons, especially because it was not considered as a progressive disease able to induce irreversible bowel damage. This has led to lower investments by the scientific community and a slower development of therapeutic options for UC. In the past few years, this trend has started to change. In fact, new promising drugs have been developed and others are emerging with positive results. Although many treatment modalities have recently been approved, additional drugs are currently being investigated and will probably be part of the UC treatment regimen in the coming years.

Abstract
BACKGROUND Ulcerative colitis is an inflammatory condition affecting the colon, with an annual incidence of approximately 10 to 20 per 100,000 people. The majority of people with ulcerative colitis can be put into remission, leaving a group who do not respond to first- or second-line therapies. There is a significant proportion of people who experience adverse effects with current therapies. Consequently, new alternatives for the treatment of ulcerative colitis are constantly being sought. Probiotics are live microbial feed supplements that may beneficially affect the host by improving intestinal microbial balance, enhancing gut barrier function and improving local immune response. OBJECTIVES The primary objective was to determine the efficacy of probiotics compared to placebo, no treatment, or any other intervention for the maintenance of remission in people with ulcerative colitis. The secondary objective was to assess the occurrence of adverse events associated with the use of probiotics. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, and two other databases on 31 October 2019. We contacted authors of relevant studies and manufacturers of probiotics regarding ongoing or unpublished trials that may be relevant to the review, and we searched ClinicalTrials.gov. We also searched references of trials for any additional trials. SELECTION CRITERIA Randomised controlled trials (RCTs) that compared probiotics against placebo or any other intervention, in both adults and children, for the maintenance of remission in ulcerative colitis were eligible for inclusion. Maintenance therapy had to be for a minimum of three months when remission has been established by any clinical, endoscopic,histological or radiological relapse as defined by study authors. DATA COLLECTION AND ANALYSIS Two review authors independently conducted data extraction and 'Risk of bias' assessment of included studies. We analysed data using Review Manager 5. We expressed dichotomous and continuous outcomes as risk ratios (RRs) and mean differences (MDs) with 95% confidence intervals (CIs). We assessed the certainty of the evidence using the GRADE methodology. MAIN RESULTS In this review, we included 12 studies (1473 randomised participants) that met the inclusion criteria. Participants were mostly adults. The studies compared probiotics to placebo, probiotics to 5-aminosalicylic acid (5-ASA) and a combination of probiotics and 5-ASA to 5-ASA. The studies ranged in length from 12 to 52 weeks. The average age of participants was between 32 and 51, with a range between 18 and 88 years. Seven studies investigated a single bacterial strain, and five studies considered mixed preparations of multiple strains. The risk of bias was high in all except three studies due to selective reporting, incomplete outcome data and lack of blinding. This resulted in low- to very low-certainty of evidence. It is uncertain if there is any difference in occurrence of clinical relapse when probiotics are compared with placebo (RR 0.87, 95% CI 0.63 to 1.18; 4 studies, 361 participants; very low-certainty evidence (downgraded for risk of bias, imbalance in baseline characteristics and imprecision)). It is also uncertain whether probiotics lead to a difference in the number of people who maintain clinical remission compared with placebo (RR 1.16, 95% CI 0.98 to 1.37; 2 studies, 141 participants; very low-certainty evidence (downgraded for risk of bias, imbalance in baseline characteristics and imprecision)). When probiotics are compared with 5-ASA, there may be little or no difference in clinical relapse (RR 1.01, 95% CI 0.84 to 1.22; 2 studies, 452 participants; low-certainty evidence) and maintenance of clinical remission (RR 1.06, 95% CI 0.90 to 1.25; 1 study, 125 participants; low-certainty evidence). It is uncertain if there is any difference in clinical relapse when probiotics, combined with 5-ASA are compared with 5-ASA alone (RR 1.11, 95% CI 0.66 to 1.87; 2 studies, 242 participants; very low-certainty evidence (downgraded due to risk of bias and imprecision)). There may be little or no difference in maintenance of remission when probiotics, combined with 5-ASA, are compared with 5-ASA alone (RR 1.05, 95% CI 0.89 to 1.24; 1 study, 122 participants; low-certainty evidence). Where reported, most of the studies which compared probiotics with placebo recorded no serious adverse events or withdrawals due to adverse events. For the comparison of probiotics and 5-ASA, one trial reported 11/110 withdrawals due to adverse events with probiotics and 11/112 with 5-ASA (RR 1.02, 95% CI 0.46 to 2.25; 222 participants; very low-certainty evidence). Discontinuation of therapy was due to gastrointestinal symptoms. One study (24 participants) comparing probiotics combined with 5-ASA with 5-ASA alone, reported no withdrawals due to adverse events; and two studies reported two withdrawals in the probiotic arm, due to avascular necrosis of bilateral femoral head and pulmonary thromboembolism (RR 5.29, 95% CI 0.26 to 107.63; 127 participants; very low-certainty evidence). Health-related quality of life and need for additional therapy were reported infrequently. AUTHORS' CONCLUSIONS The effectiveness of probiotics for the maintenance of remission in ulcerative colitis remains unclear. This is due to low- to very low-certainty evidence from poorly conducted studies, which contribute limited amounts of data from a small number of participants. Future trials comparing probiotics with 5-ASA rather than placebo will better reflect conventional care given to people with ulcerative colitis. Appropriately powered studies with a minimum length of 12 months are needed.

There is a significant proportion of people who experience adverse effects with current therapies. Consequently, new alternatives for the treatment of ulcerative colitis are constantly being sought. Probiotics are live microbial feed supplements that may beneficially affect the host by improving intestinal microbial balance, enhancing gut barrier function and improving local immune response. OBJECTIVES To assess the efficacy of probiotics compared with placebo or standard medical treatment (5-aminosalicylates, sulphasalazine or corticosteroids) for the induction of remission in people with active ulcerative colitis. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, and two other databases on 31 October 2019. We contacted authors of relevant studies and manufacturers of probiotics regarding ongoing or unpublished trials that may be relevant to the review, and we searched ClinicalTrials.gov. We also searched references of trials for any additional trials. SELECTION CRITERIA Randomised controlled trials (RCTs) investigating the effectiveness of probiotics compared to standard treatments or placebo in the induction of remission of active ulcerative colitis. We considered both adults and children, with studies reporting outcomes of clinical, endoscopic, histologic or surgical remission as defined by study authors DATA COLLECTION AND ANALYSIS: Two review authors independently conducted data extraction and 'Risk of bias' assessment of included studies. We analysed data using Review Manager 5. We expressed dichotomous and continuous outcomes as risk ratios (RRs) and mean differences (MDs) with 95% confidence intervals (CIs). We assessed the certainty of the evidence using the GRADE methodology. MAIN RESULTS In this review, we included 14 studies (865 randomised participants) that met the inclusion criteria. Twelve of the studies looked at adult participants and two studies looked at paediatric participants with mild to moderate ulcerative colitis, the average age was between 12.5 and 47.7 years. The studies compared probiotics to placebo, probiotics to 5-ASA and a combination of probiotics plus 5-ASA compared to 5-ASA alone. Seven studies used a single probiotic strain and seven used a mixture of strains. The studies ranged from two weeks to 52 weeks. The risk of bias was high for all except two studies due to allocation concealment, blinding of participants, incomplete reports of outcome data and selective reporting. This led to GRADE ratings of the evidence ranging from moderate to very low. Probiotics versus placebo Probiotics may induce clinical remission when compared to placebo (RR 1.73, 95% CI 1.19 to 2.54; 9 studies, 594 participants; low-certainty evidence; downgraded due to imprecision and risk of bias, number needed to treat for an additional beneficial outcome (NNTB) 5). Probiotics may lead to an improvement in clinical disease scores (RR 2.29, 95% CI 1.13 to 4.63; 2 studies, 54 participants; downgraded due to risk of bias and imprecision). There may be little or no difference in minor adverse events, but the evidence is of very low certainty (RR 1.04, 95% CI 0.42 to 2.59; 7 studies, 520 participants). Reported adverse events included abdominal bloating and discomfort. Probiotics did not lead to any serious adverse events in any of the seven studies that reported on it, however five adverse events were reported in the placebo arm of one study (RR 0.09, CI 0.01 to 1.66; 1 study, 526 participants; very low-certainty evidence; downgraded due to high risk of bias and imprecision). Probiotics may make little or no difference to withdrawals due to adverse events (RR 0.85, 95% CI 0.42 to 1.72; 4 studies, 401 participants; low-certainty evidence). Probiotics versus 5-ASA There may be little or no difference in the induction of remission with probiotics when compared to 5-ASA (RR 0.92, 95% CI 0.73 to 1.16; 1 study, 116 participants; low-certainty evidence; downgraded due to risk of bias and imprecision). There may be little or no difference in minor adverse events, but the evidence is of very low certainty (RR 1.33, 95% CI 0.53 to 3.33; 1 study, 116 participants). Reported adverse events included abdominal pain, nausea, headache and mouth ulcers. There were no serious adverse events with probiotics, however perforated sigmoid diverticulum and respiratory failure in a patient with severe emphysema were reported in the 5-ASA arm (RR 0.21, 95% CI 0.01 to 4.22; 1 study, 116 participants; very low-certainty evidence). Probiotics combined with 5-ASA versus 5-ASA alone Low-certainty evidence from a single study shows that when combined with 5-ASA, probiotics may slightly improve the induction of remission (based on the Sunderland disease activity index) compared to 5-ASA alone (RR 1.22 CI 1.01 to 1.47; 1 study, 84 participants; low-certainty evidence; downgraded due to unclear risk of bias and imprecision). No information about adverse events was reported. Time to remission, histological and biochemical outcomes were sparsely reported in the studies. None of the other secondary outcomes (progression to surgery, need for additional therapy, quality of life scores, or steroid withdrawal) were reported in any of the studies. AUTHORS' CONCLUSIONS Low-certainty evidence suggests that probiotics may induce clinical remission in active ulcerative colitis when compared to placebo. There may be little or no difference in clinical remission with probiotics alone compared to 5-ASA. There is limited evidence from a single study which failed to provide a definition of remission, that probiotics may slightly improve the induction of remission when used in combination with 5-ASA. There was no evidence to assess whether probiotics are effective in people with severe and more extensive disease, or if specific preparations are superior to others. Further targeted and appropriately designed RCTs are needed to address the gaps in the evidence base. In particular, appropriate powering of studies and the use of standardised participant groups and outcome measures in line with the wider field are needed, as well as reporting to minimise risk of bias.
