Abstract
Perianal fistulizing Crohn's disease (CD) represents a severe phenotype of CD that is associated with significant morbidity and reduction in quality of life. Perianal fistulizing CD is caused by a complex interplay of genetic predisposition, immune dysregulation, gut dysbiosis, and various unknown physiological and mechanical factors. A multidisciplinary approach is hence required for optimal management . A detailed anatomical description and classification of perianal fistula, including comprehensive clinical, endoscopic, and radiological diagnostic workup, is an important prerequisite to treatment. For simple perianal fistulas, use of antibiotics and immunomodulators, with or without fistulotomy, are appropriate measures. The medical management of complex perianal fistula, on the other hand, requires adequate control of infection before initiation of therapy with immunomodulators. In active complex perianal fistula, anti-tumor necrosis factors remain the most accepted therapy, with concomitant use of antibiotics or immunomodulators enhancing the efficacy. For patients refractory to anti-tumor necrosis factors, treatment with anti-integrins, anti-interleukins, and small molecules is being evaluated. Mesenchymal stem cells, hyperbaric oxygen therapy, and exclusive enteral nutrition have also been investigated as adjunct therapies. Despite the expansion of the medical armamentarium, a large proportion of the patients require surgical interventions. In this review, we provide an up-to-date overview of the pathophysiology, clinical presentation, diagnosis, and medical management of perianal fistulizing CD. A brief overview of the surgical management of perianal fistulizing CD is also provided.

Differences in the risk of clinical failure between thiopurine and methotrexate in bio-naïve patients with Crohn's disease: a Korean nationwide population-based study. Therap Adv Gastroenterol 2024; 17:17562848241248321. [PMID: 38741927 PMCID: PMC11089848 DOI: 10.1177/17562848241248321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Accepted: 03/31/2024] [Indexed: 05/16/2024] Open
Abstract
Background Although immunomodulators are widely prescribed in patients with Crohn's disease (CD), it is unclear whether there is a difference in treatment outcomes between thiopurines and methotrexate (MTX). Objective To compare the risk of clinical failure between thiopurines and MTX in bio-naïve patients with CD. Design Nationwide, population-based study. Methods We used claims data from the Korean National Health Insurance Service. After inverse probability of treatment weighting, logistic regression and Cox proportional hazard analyses were used to evaluate the risk of clinical failure in bio-naïve patients with CD treated with thiopurine (thiopurine group) or MTX (MTX group). Results Overall, 10,296 adult and pediatric patients with CD [9912 (96.3%) and 384 (3.7%) in the thiopurine and MTX groups, respectively] were included. The odds ratios (ORs) of failure to induce remission were significantly higher in the MTX group than in the thiopurine group [adjusted OR (aOR), 1.115; 95% confidence interval (CI), 1.045-1.190; p = 0.001]. However, the opposite result was observed only in patients without concomitant steroid use: the MTX group had a lower risk of induction failure than the thiopurine group (aOR, 0.740; 95% CI, 0.673-0.813; p < 0.001). The risk of overall maintenance failure was higher in the MTX group than in the thiopurine group [adjusted hazard ratio (aHR), 1.117; 95% CI, 1.047-1.191; p = 0.001]. The risk of overall maintenance failure was higher in the standard-dose MTX group than in the low-dose MTX group (aHR, 1.296; 95% CI, 1.134-1.480; p < 0.001). There was no significant difference in the risk of maintenance failure according to the administration route of MTX. Conclusion Thiopurine is more effective than MTX in inducing and maintaining remission in bio-naïve patients with CD; however, the concomitant use of steroids influences inducing remission.

Abstract
BACKGROUND Fistulas are a debilitating complication of Crohn's disease [CD]. We conducted a systematic review to assess the efficacy of medical therapies for fistulizing CD. METHODS MEDLINE, Embase, and CENTRAL were searched on May 26, 2022, for randomized controlled trials [RCTs] of pharmacological therapy in adults with fistulizing CD. The primary outcome was induction and maintenance of fistula response. Pooled risk ratios [RRs] and 95% confidence intervals [CIs] were calculated. GRADE was used to assess the certainty of evidence. RESULTS Thirty-eight RCTs were included. Nineteen trials [50%] exclusively involved perianal fistula. The remaining studies included some participants with non-perianal fistula. Pooled RRs for anti-tumour necrosis factor [TNF] agents were not statistically significant for induction [RR 1.36, 95% CI 0.97-1.91] or maintenance of fistula response [RR 1.48, 95% CI 0.97-2.27]. However, in a sensitivity analysis of studies with fistula response as the primary outcome, anti-TNFs were superior to placebo for induction [RR 1.94, 95% CI 1.10-3.41] and maintenance [RR 1.88, 95% CI 1.23-2.88] of fistula response. Oral small molecules [RR 2.56, 95% CI 1.18-5.53] and mesenchymal stem cell [MSC] therapy [RR 1.26, 95% CI 1.01-1.57] were effective for induction of fistula response. Ustekinumab was associated with maintenance of fistula response [RR 1.80, 95% CI 1.04-3.11]. Vedolizumab was not superior to placebo. The certainty of evidence ranged from very low to moderate. CONCLUSION Very low- to moderate-certainty evidence suggests that anti-TNF therapy, oral small molecules, ustekinumab, and MSCs are effective for perianal fistulizing CD. Dedicated fistula studies evaluating biologics and small molecules are needed.

Abstract
A treat-to-target (T2T) approach applies the principles of early intervention and tight disease control to optimise long-term outcomes in Crohn's disease. The Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE)-II guidelines specify short, intermediate, and long-term treatment goals, documenting specific treatment targets to be achieved at each of these timepoints. Scheduled appraisal of Crohn's disease activity against pre-defined treatment targets at these timepoints remains central to determining whether current therapy should be continued or modified. Consensus treatment targets in Crohn's disease comprise combination clinical and patient-reported outcome remission, in conjunction with biomarker normalisation and endoscopic healing. Although the STRIDE-II guidelines endorse the pursuit of endoscopic healing, clinicians must consider that this may not always be appropriate, acceptable, or achievable in all patients. This underscores the need to engage patients at the outset in an effort to personalise care and individualise treatment targets. The use of non-invasive biomarkers such as faecal calprotectin in conjunction with cross-sectional imaging techniques, particularly intestinal ultrasound, holds great promise; as do emerging treatment targets such as transmural healing. Two randomised clinical trials, namely, CALM and STARDUST, have evaluated the efficacy of a T2T approach in achieving endoscopic endpoints in patients with Crohn's disease. Findings from these studies reflect that patient subgroups and Crohn's disease characteristics likely to benefit most from a T2T approach, remain to be clarified. Moreover, outside of clinical trials, data pertaining to the real-world effectiveness of a T2T approach remains scare, highlighting the need for pragmatic real-world studies. Despite the obvious promise of a T2T approach, a lack of guidance to support its integration into real-world clinical practice has the potential to limit its uptake. This highlights the need to describe strategies, processes, and models of care capable of supporting the integration and execution of a T2T approach in real-world clinical practice. Hence, this review seeks to examine the current and emerging literature to provide clinicians with practical guidance on how to incorporate the principles of T2T into routine clinical practice for the management of Crohn's disease.

Abstract
BACKGROUND Inflammatory bowel diseases (IBDs) are chronic, recurrent inflammatory diseases with partly understood etiology and pathogenesis. The course of IBD, both ulcerative colitis and Crohn's disease, is characterized by periods of relapse and remission with the possible occurrence of extraintestinal manifestations. SUMMARY During the last decades, therapeutic goals in IBD evolved toward endoscopic remission and mucosal healing creating the need for early administration of disease-modifying agents (DMAs). DMAs include conventional immunosuppressants (thiopurines, methotrexate), biologic drugs (anti-TNF, anti-integrin, and anti-IL-12/23 monoclonal antibodies), and small molecules (JAK inhibitors, S1P receptor modulators). Patients with aggressive course of disease and risk factors for poor prognosis should be treated with biologic therapy early, while conventional immunomodulators should be used in those with milder course of disease in the absence of risk factors. KEY MESSAGES Challenges in the treatment of IBD patients include the choice of effective yet safe drug and prevention or overcoming loss of response.

Abstract
BACKGROUND Thiopurines and methotrexate have long been used to maintain remission in Crohn's disease [CD]. In this nationwide study, we aimed to compare the effectiveness and safety of these drugs in CD. METHODS We used data from the epi-IIRN cohort, including all patients with CD diagnosed in Israel. Outcomes were compared by propensity-score matching and included therapeutic failure, hospitalisations, surgeries, steroid dependency, and adverse events. RESULTS Of the 19264 patients diagnosed with CD since 2005, 3885 [20%] ever received thiopurines as monotherapy and 553 [2.9%] received methotrexate. Whereas the use of thiopurines declined from 22% in 2012-2015 to 12% in 2017-2020, the use of methotrexate remained stable. The probability of sustaining therapy at 1, 3, and 5 years was 64%, 51%, and 44% for thiopurines and 56%, 30%, and 23% for methotrexate, respectively [p <0.001]. Propensity-score matching, including 303 patients [202 with thiopurines, 101 with methotrexate], demonstrated a higher rate of 5-year durability for thiopurines [40%] than methotrexate [18%; p <0.001]. Time to steroid dependency [p = 0.9], hospitalisation [p = 0.8], and surgery [p = 0.1] were comparable between groups. These outcomes reflect also shorter median time to biologics with methotrexate (2.2 [IQR 1.6-3.1 years) versus thiopurines (6.6 [2.4-8.5]; p = 0.02). The overall adverse events rate was higher with thiopurines [20%] than methotrexate [12%; p <0.001], including three lymphoma cases in males, although the difference was not significant [4.8 vs 0 cases/10 000 treatment-years, respectively; p = 0.6]. CONCLUSION Thiopurines demonstrated higher treatment durability than methotrexate but more frequent adverse events. However, disease outcomes were similar, partly due to more frequent escalation to biologics with methotrexate.

Abstract
BACKGROUND AND AIMS Crohn's disease [CD] can develop penetrating complications at any time during the disease course. Enterocutaneous fistulae [ECF] are disease-related complications with an important impact on quality of life. Our aim was to describe the outcomes of this complication, including its medical and/or surgical management and their temporal trends. The primary endpoint was fistula closure, defined as the absence of drainage, with no new abscess or surgery, over the preceding 6 months. METHODS Clinical information from all adult patients with CD and at least one ECF-excluding perianal fistulae-were identified from the prospectively-maintained ENEIDA registry. All additional information regarding treatment for this complication was retrospectively reviewed. RESULTS A total of 301 ECF in 286 patients [January 1970-September 2020] were analysed out of 30 088 records. These lesions were mostly located in the ileum [67%] and they had a median of one external opening [range 1-10]. After a median follow-up of 146 months (interquartile range [IQR], 69-233), 69% of patients underwent surgery. Fistula closure was achieved in 84%, mostly after surgery, and fistula recurrence was uncommon [13%]. Spontaneous and low-output fistulae were associated with higher closure rates (hazard ratio [HR] 1.51, 95% confidence interval [CI] 1.17-1.93, p = 0.001, and HR 1.49, 95% CI 1.07-2.06, p = 0.03, respectively); this was obtained more frequently with medical therapy since biologics have been available. CONCLUSIONS ECF complicating CD are rare but entail a high burden of medical and surgical resources. Closure rates are high, usually after surgery, and fistula recurrence is uncommon. A significant proportion of patients receiving medical therapy can achieve fistula closure.

Abstract
BACKGROUND One quarter of the world's population has latent tuberculosis infection (LTBI). Systemic immunosuppression is a risk factor for LTBI reactivation and the development of active tuberculosis. Such reactivation carries a risk of significant morbidity and mortality. Despite the increasing global incidence of inflammatory bowel disease (IBD) and the use of immune-based therapies, current guidelines on the testing and treatment of LTBI in patients with IBD are haphazard with a paucity of evidence. AIM To review the screening, diagnostic practices and medical management of LTBI in patients with IBD. METHODS Published literature was reviewed, and recommendations for testing and treatment were synthesised by experts in both infectious diseases and IBD. RESULTS Screening for LTBI should be performed proactively and includes assessment of risk factors, an interferon-gamma releasing assay or tuberculin skin test and chest X-ray. LTBI treatment in patients with IBD is scenario-dependent, related to geographical endemicity, travel and other factors. Ideally, LTBI therapy should be used prior to immune suppression but can be applied concurrently where urgent IBD medical treatment is required. Management is best directed by a multidisciplinary team involving gastroenterologists, infectious diseases specialists and pharmacists. Ongoing surveillance is recommended during therapy. Newer LTBI therapies show promise, but medication interactions need to be considered. There are major gaps in evidence, particularly with specific newer therapeutic approaches to IBD. CONCLUSIONS Proactive screening for LTBI is essential in patients with IBD undergoing immune-suppressing therapy and several therapeutic strategies are available. Reporting of real-world experience is essential to refining current management recommendations.

Abstract
The incidence of inflammatory bowel disease with its two main manifestations, colitis ulcerosa and Crohn's disease, is rising globally year after year. There is still a tremendous need to study the underlying pathomechanisms and a well-established tool in order to better understand the disease are colitis models in rodents. Since the concept of the 3Rs was proposed by Russell and Burch, this would include pain medication in animal models of intestinal inflammation as a reduction of suffering. This review argues against pain medication because the administration of pain medication in its current form has an impact on the inflammatory process and the immune response, thus falsifying the results and the reproducibility and therefore leading to misconceptions.

Evidence-based efficacy of methotrexate in adult Crohn's disease in different intestinal and extraintestinal indications. Therap Adv Gastroenterol 2022; 15:17562848221085889. [PMID: 35340755 PMCID: PMC8949794 DOI: 10.1177/17562848221085889] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Accepted: 02/18/2022] [Indexed: 02/04/2023] Open
Abstract
INTRODUCTION Methotrexate (MTX) is included in the therapeutic armamentarium of Crohn's disease (CD), although its positioning is currently uncertain in an era in which many effective biological drugs are available. No systematic reviews or meta-analysis have stratified the clinical outcomes of MTX according to the specific clinical scenarios of its use. METHODS Medline, PubMed and Scopus were used to extract eligible studies, from database inception to May 2021. A total of 163 studies were included. A systematic review was performed by stratifying the outcomes of MTX according to formulation, clinical indication and criteria of efficacy. RESULTS The use of MTX is supported by randomized clinical trials only in steroid-dependent CD, with similar outcomes to thiopurines. The use of MTX in patients with steroid-refractoriness, failure of thiopurines or in combination with biologics is not supported by high levels of evidence. Combination therapy with biologics can optimize the immunogenic profile of the biological drug, but the impact on long-term clinical outcomes is described only in small series with anti-TNFα. Other off-label uses, such as fistulizing disease, mucosal healing, postoperative prevention and extraintestinal manifestations, are described in small uncontrolled series. The best performance in most indications was shown by parenteral MTX, favouring higher doses (25 mg/week) in the induction phase. DISCUSSION Evidence from high-quality studies in favour of MTX is scarce and limited to the steroid-dependent disease, in which other drugs are the leading players today. Many limitations on study design have been found, such as the prevalence of retrospective underpowered studies and the lack of stratification of outcomes according to specific types of patients and formulations of MTX. CONCLUSION MTX is a valid option as steroid-sparing agent in steroid-dependent CD. Numerous other clinical scenarios require well-designed clinical studies in terms of patient profile, drug formulation and dosage, and criteria of efficacy.

Abstract
OBJECTIVES To evaluate quality of life (QoL) in a large cohort of pediatric patients with inflammatory bowel disease (IBD) and to identify the clinical factors that influence QoL. STUDY DESIGN This cross-sectional study analyzes a quality improvement initiative in 351 pediatric patients with IBD in British Columbia, Canada using the self-reported Pediatric Quality of Life Inventory (PedsQL) 4.0 generic scale. The questionnaire was completed at outpatient clinic and biologic infusion appointments. Statistical analysis included the t test, ANOVA, and multilinear regressions to evaluate the relationships between clinical factors and QoL. RESULTS Mean (SE) QoL scores (79.95 [0.84]) fell between previously described healthy and chronically ill populations. Disease activity was the most significant predictor of QoL, with patients in remission scoring similar (84.42 [0.87]) to well established healthy norms, and those with moderately or severely active disease having some of the lowest published PedsQL scores (63.13 [3.27]), lower than most other chronic pediatric conditions. Twenty-five patients with moderately or severely active disease at the time of survey completion had follow-up surveys identified 1 year later and had a significant improvement of both their disease activity (P < .005) and their PedsQL scores (follow-up survey mean 76.13 [3.11]). Additional clinical factors independently associated with poor QoL were school nonattendance (15.5% decrease in QoL, P < .001), immune-modulator selection (methotrexate conferring a 9.5% lower mean QoL score than azathioprine, P = .005), and female gender (P = .031). CONCLUSION Pediatric patients with IBD experience a QoL significantly impacted by multiple clinical factors including current severity of IBD symptoms.

The Evidence From the Network Meta-Analysis. Front Med (Lausanne) 2021; 8:679258. [PMID: 34540859 PMCID: PMC8440847 DOI: 10.3389/fmed.2021.679258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Accepted: 08/09/2021] [Indexed: 11/13/2022] Open
Abstract
Background: Several drugs currently are available for the treatment of Crohn's disease, including non-biological agents such as anti-inflammatory agents, steroids, immunosuppressive agents, and biologic agents such as anti-tumor necrosis factor (TNF), anti-α4β7 integrin, anti-alpha-4 integrin and anti-interleukin 12/23. However, the choice of treatments for induction and maintenance is still a challenge. The relevant comparison between non-biologic agents and biologic agents is few. In our research, we aimed to help making decisions, as well as providing clinicians and patients with medication references. Methods: We searched MEDLINE, Embase, and the Cochrane Central Register of controlled trials for relevant randomized controlled trials published through to July 2020 and systematic reviews published from January 2011 to December 2020. Search results were screened by 2 independent reviewers first by title and abstract and then by full text. Disagreements were resolved through discussion with a third reviewer. Results: 54 randomized controlled trials were included in our analysis. For induction of remission, azathioprine (OR, 3.5; 95% Crl, 1.4–8.9), infliximab (OR, 4.1; 95% Crl, 1.2–16.0), infliximab + azathioprine (OR, 7.0; 95% Crl, 1.2–41.0) and infliximab+ methotrexate (OR, 7.8; 95% Crl, 1.2–65.0) were more effective in first-line therapy than placebo. Adalimumab showed superiority to placebo in second-line therapy, but the range of SD was wide. For maintenance of remission, adalimumab (OR,2.24;95% Crl,1.17–4.76) and azathioprine (OR,2.05; 95% Crl,1.14–3.96) were more effective than placebo. Adalimumab (OR,0.56; 95%Crl,0.27–1.2), budesonide (OR,0.63; 95%Crl,0.26–1.6) and natalizumab (OR,0.65; 95%Crl,0.30–1.4) was associated with less risk of withdrawals when compared with placebo. Conclusion: For induction of remission, azathioprine, infliximab, and infliximab + azathioprine were more effective in first-line therapy. In second-line therapy, adalimumab was more effective but should be interpreted carefully. For maintenance of remission, adalimumab and azathioprine were more effective. Besides, adalimumab, budesonide, natalizumab had lower withdrawals. Therefore, biological agents were not always better than non-biological agents and they have their own advantages in different treatment methods of Crohn's disease.

Short-term tolerability and effectiveness of methotrexate monotherapy in adult patients with Crohn's disease: a retrospective study. Therap Adv Gastroenterol 2021; 14:17562848211043017. [PMID: 34539814 PMCID: PMC8442506 DOI: 10.1177/17562848211043017] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2021] [Accepted: 08/03/2021] [Indexed: 02/04/2023] Open
Abstract
INTRODUCTION Immunomodulators remain fundamental for the medical treatment of Crohn's disease (CD). Methotrexate (MTX) is widely used as a second-line immunomodulator; however, there is a lack of recent data on MTX monotherapy among the Asian population with CD. Therefore, in this study, we aimed to investigate the tolerability and clinical outcomes of MTX in Korean patients with CD. METHODS A retrospective chart review was performed for CD patients treated with MTX monotherapy or in combination with 5-aminosalicylic acid (5-ASA), at the Asan Medical Center, Seoul, South Korea. The tolerability of MTX monotherapy within 6 months was assessed and the clinical effectiveness of MTX was evaluated based on the Crohn's disease activity index (CDAI). RESULTS In total, 85 patients were included, of which 29 (34.1%) discontinued MTX due to intolerability during the follow-up. Adverse events (AEs) were reported in 41 (48.2%) patients. The most common AE was gastrointestinal disorders (17/41) and only one patient experienced a serious AE, a systemic infection that required hospitalization. Among the 56 patients who tolerated MTX within 6 months, 44 (65.9%) showed a clinical response. Moreover, no factor was significantly associated with intolerability. The administration method was the only factor significantly associated with a response to MTX (p = 0.041). The adjusted odds ratio of parenteral injection compared to oral administration was 5.68 (95% confidence interval (CI), 1.07-30.08). CONCLUSION In this study, one-third of patients were intolerant to MTX; nonetheless, the response rate was as high as 65.9% among tolerant patients. In addition, no significant factors affected intolerability. In terms of the clinical response, parenteral injection could be better than oral administration.

Abstract
Over the 21st century, inflammatory bowel disease (IBD) has become a global disease with increasing prevalence reported in the Asian subcontinent as a result of rapid urbanisation, industrialisation, and westernisation of lifestyles. Although rates of surgery have shown a temporal decrease globally because of the increasing availability of new drugs and early initiation of effective therapy, health-care costs associated with IBD have continued to rise. The increase in IBD prevalence in resource-limited countries poses a substantial health-care burden. Drugs are not universally accessible or available. An optimised and practical management strategy of IBD in resource-limited countries in Asia is urgently needed. Special consideration should be made to balance the risk of undertreatment (and suboptimal disease control) because of financial constraints with the risk of overtreatment, which is associated with side-effects and costly therapeutics. In this Series paper, we summarise the current approach in optimising conventional therapies, use of other therapies, and de-escalation of biologics in low-resource settings in Asia. The long-term objective is to strive for more effective and affordable therapies with sustained durability of benefit.

Abstract
OBJECTIVE We aimed to provide an evidence-supported update of the ECCO-ESPGHAN guideline on the medical management of paediatric Crohn's disease [CD]. METHODS We formed 10 working groups and formulated 17 PICO-structured clinical questions [Patients, Intervention, Comparator, and Outcome]. A systematic literature search from January 1, 1991 to March 19, 2019 was conducted by a medical librarian using MEDLINE, EMBASE, and Cochrane Central databases. A shortlist of 30 provisional statements were further refined during a consensus meeting in Barcelona in October 2019 and subjected to a vote. In total 22 statements reached ≥ 80% agreement and were retained. RESULTS We established that it was key to identify patients at high risk of a complicated disease course at the earliest opportunity, to reduce bowel damage. Patients with perianal disease, stricturing or penetrating behaviour, or severe growth retardation should be considered for up-front anti-tumour necrosis factor [TNF] agents in combination with an immunomodulator. Therapeutic drug monitoring to guide treatment changes is recommended over empirically escalating anti-TNF dose or switching therapies. Patients with low-risk luminal CD should be induced with exclusive enteral nutrition [EEN], or with corticosteroids when EEN is not an option, and require immunomodulator-based maintenance therapy. Favourable outcomes rely on close monitoring of treatment response, with timely adjustments in therapy when treatment targets are not met. Serial faecal calprotectin measurements or small bowel imaging [ultrasound or magnetic resonance enterography] are more reliable markers of treatment response than clinical scores alone. CONCLUSIONS We present state-of-the-art guidance on the medical treatment and long-term management of children and adolescents with CD.

Abstract
BACKGROUND There are safety concerns regarding immunomodulators (thiopurines and methotrexate) for treatment of inflammatory bowel disease (IBD). AIM To compare the long-term tolerability, and persistence of thiopurine and methotrexate therapy in IBD. METHODS A retrospective cohort study was performed at two hospitals between 1 January 2004 and 31 December 2016 for patients commenced on thiopurines or methotrexate for IBD. Treatment discontinuation rates, intolerances and disease activity were obtained from medical records. RESULTS There were 782 patients commenced on immunomodulator therapy; 244 (31%) on methotrexate with folate (67% subcutaneous therapy) and 538 (69%) on thiopurine (73% azathioprine). Median follow-up was 42 vs 47 months (P = 0.09). In patients on thiopurines, median 6-TGN was 298 pmol/8 x 108 RBCs, while the median dose of methotrexate was 25 mg weekly. Methotrexate recipients had a higher rate of prior immunomodulator intolerance, were typically older and had a longer disease duration (54% vs 3%, median 43 vs 36 years, 6 vs 5 years, respectively, each P < 0.05). Overall, 208 (27%) discontinued therapy due to adverse events, (40% on methotrexate vs 19% on thiopurines, P < 0.001), including nausea (18% vs 4%), fatigue (7% vs 2%) and hepatotoxicity (8% vs 2%, each P < 0.001). Hospitalisations from adverse events (0.8% vs 0.9%) and serious infections (9% vs 12%), and deaths (1% vs 0%) were comparable between groups (all P > 0.05). Discontinuation due to adverse events occurred later in patients on methotrexate than on thiopurines (median 7 vs 5 months, P = 0.08). CONCLUSION Discontinuation of methotrexate occurred at rates twice that of dose-optimised thiopurine therapy.

Abstract
INTRODUCTION Immunomodulators such as thiopurines (azathioprine (AZA)/6-mercaptopurine (6MP)), methotrexate (MTX) and biologics such as adalimumab (ADA) are well established for maintenance of remission within paediatric Crohn's disease (CD). It remains unclear, however, which maintenance medication should be used first line in specific patient groups. AIMS To compare the efficacy of maintenance therapies in newly diagnosed CD based on stratification into high and low-risk groups for severe CD evolution; MTX versus AZA/6MP in low-risk and MTX versus ADA in high-risk patients. Primary end point: sustained remission at 12 months (weighted paediatric CD activity index ≤12.5 and C reactive protein ≤1.5 fold upper limit) without relapse or ongoing requirement for exclusive enteral nutrition (EEN)/steroids 12 weeks after treatment initiation. METHODS AND ANALYSIS REDUCE-RISK in CD is an international multicentre open-label prospective randomised controlled trial funded by EU within the Horizon2020 framework (grant number 668023). Eligible patients (aged 6-17 years, new-onset disease receiving steroids or EEN for induction of remission for luminal ± perianal CD are stratified into low and high-risk groups based on phenotype and response to induction therapy. Participants are randomised to one of two treatment arms within their risk group: low-risk patients to weekly subcutaneous MTX or daily oral AZA/6MP, and high-risk patients to weekly subcutaneous MTX or fortnightly ADA. Patients are followed up for 12 months at prespecified intervals. Electronic case report forms are completed prospectively. The study aims to recruit 312 participants (176 low risk; 136 high risk). ETHICS AND DISSEMINATION ClinicalTrials.gov Identifier: (NCT02852694), authorisation and approval from local ethics committees have been obtained prior to recruitment. Individual informed consent will be obtained prior to participation in the study. Results will be published in a peer-reviewed journal with open access. TRIAL REGISTRATION NUMBER NCT02852694; Pre-results.

Frontline Gastroenterol 2020; 12:423-436. [PMID: 35401955 PMCID: PMC8989005 DOI: 10.1136/flgastro-2020-101405] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2020] [Revised: 04/14/2020] [Accepted: 05/14/2020] [Indexed: 02/04/2023] Open
Abstract
Thiopurines are proven agents in the treatment of Crohn's disease. While pancreatitis is recognised as an adverse event associated with therapy, the effect size and morbidity of thiopurine-induced pancreatitis is not known. The aim of this systematic review and meta-analysis was to quantify the risk of pancreatitis with azathioprine and 6-mercaptopurine (6-MP) within Crohn's disease. We searched six electronic databases from inception to 29 October 2019. The primary outcomes measures were the occurrence of pancreatitis. We calculated pooled OR with corresponding 95% CIs for risk of pancreatitis. A number needed to harm analysis was performed. The search identified 4418 studies, of which 25 randomised controlled trials met the criteria for inclusion. The number of patients treated with azathioprine to cause an episode of pancreatitis was 36 (induction of remission) and 31 (maintenance of remission). The risk of pancreatitis in patients receiving azathioprine across all contexts was 3.80%, compared with a control risk of 0.2% (placebo) and 0.5% (5-aminosalicylic acid agents). There was no difference seen between 6-MP and placebo, although this was a low certainty result due to imprecision from very low event numbers and patient numbers. There is a probably increased occurrence of pancreatitis when azathioprine is used in Crohn's disease (moderate certainty), with incidence overall approximately 3.8%. Most cases are mild and resolve on cessation of therapy and no mortality was reported. There was no increased occurrence seen when using 6-MP, although this is a low certainty finding. PROSPERO prior to the study (CRD42019138065).

Efficacy and safety of methotrexate in the management of inflammatory bowel disease: A systematic review and meta-analysis of randomized, controlled trials. EClinicalMedicine 2020; 20:100271. [PMID: 32300735 PMCID: PMC7152823 DOI: 10.1016/j.eclinm.2020.100271] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2019] [Revised: 01/16/2020] [Accepted: 01/16/2020] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND The therapeutic role of methotrexate (MTX) for management of inflammatory bowel disease (IBD) remains unclear. METHODS We systematically reviewed randomized, controlled trials (RCTs) of MTX for induction and maintenance of remission in IBD until January 2020 in accordance with PROSPERO protocol (#CRD42018115047). Relative risk (RR) of maintenance of remission, induction of remission, endoscopic disease activity, and adverse events were combined in a meta-analysis. FINDINGS MTX monotherapy was not superior to placebo for induction of clinical remission in Crohn's disease (CD). However, MTX was superior to placebo in maintaining clinical remission of CD. Concomitant therapy with MTX and the TNF inhibitor infliximab (IFX) was not superior to IFX monotherapy in CD. In ulcerative colitis (UC), MTX monotherapy was not superior to placebo neither for induction of clinical remission, nor for maintenance of clinical remission. MTX did not result in superior endoscopic outcomes during induction or maintenance therapy compared with placebo. Regarding adverse events (AEs), our meta-analysis on CD studies showed a significantly higher risk of AEs when comparing MTX versus placebo in studies investigating induction of remission, but not in maintenance of remission. In UC, no such differences in AEs between MTX or placebo were observed. INTERPRETATION Current data support the efficacy of parenteral MTX monotherapy for maintenance of clinical remission in CD. MTX is not confirmed to be effective for treatment of UC or for induction of remission in CD. No evidence supports concomitant MTX to improve efficacy of IFX (no other biologics investigated).

Abstract
Crohn’s disease may severely impact the quality of life and being a chronic disease it requires
both medical and surgical treatment aimed at induction and maintenance of remission to prevent
relapsing symptoms and the need for further surgery. Surgery in Crohn’s disease often has to be
performed in patients with well-known risk factors of post-operative complications, particularly intraabdominal
septic complications. This review will look at the current knowledge of immunomodulating
therapies in the peri-operative phase of Crohn’s disease. The influence of immunomodulators on postoperative
complications is evaluated by reviewing available clinical reports and data from animal
studies. Furthermore, the effect of immunomodulators on preventing or deferring primary as well as
repeat surgery in Crohn’s disease is reviewed with particular consideration given to high-risk cohorts
and timing of prophylaxis.

Abstract
BACKGROUND The differential impact of anti-tumor necrosis factor (anti-TNF) therapy with methotrexate versus thiopurine co-therapy on endoscopic remission remains uncertain. AIMS To compare rates of endoscopic remission based on methotrexate or thiopurine co-therapy used with anti-TNF therapy in Crohn's disease. METHODS A retrospective observational study at two tertiary centers between 2010 and 2016 compared endoscopic remission rates and persistence on anti-TNF therapy in combination with methotrexate versus thiopurines for at least 3 months. RESULTS Of 412 patients on anti-TNF therapy, 278 (67%) received immunomodulator co-therapy for ≥ 3 months and 269 (65%) had complete data for analysis. Methotrexate was used in 77 (29%) and thiopurines in 192 (71%) patients plus either infliximab (156, 58%) or adalimumab (113, 42%), with median follow-up of 2.8 years. The methotrexate group had greater prior immunomodulator intolerance (62% vs 20%, p < 0.01). Endoscopic remission rates were higher in those treated with thiopurine compared to methotrexate co-therapy at 12 m (58% vs 17%, p < 0.01) and at last review (59% vs 40%, p = 0.03). Endoscopic remission rates were higher with thiopurines than methotrexate when combined with adalimumab (49% vs 6%, p < 0.01) but not with infliximab (65% vs 54%, p = 0.09). In multivariate analysis, thiopurine co-therapy, elevated baseline CRP, and therapeutic anti-TNF drug levels were each associated with longer persistence of co-therapy (each p < 0.05). There were no significant differences in adverse events, malignancy or infection rates. CONCLUSION In this cohort, anti-TNF and thiopurine co-therapy resulted in higher rates of mucosal healing than methotrexate, the difference is most pronounced with adalimumab and conversely with low-dose methotrexate.

Abstract
BACKGROUND The suitability of disease activity indices has been challenged, with growing interest in objective measures of inflammation. AIM To undertake a systematic review of efficacy and safety outcomes in placebo-controlled randomised controlled trials (RCTs) of patients with Crohn's disease. METHODS MEDLINE, EMBASE, CINAHL and Cochrane Library were searched until November 2015, for RCTs of adult Crohn's disease patients treated with medical or surgical therapies. Data on efficacy and safety outcomes, end-point definitions, and measurement instruments were extracted and stratified by publication date (pre-2009 and 2009 onwards). RESULTS One hundred and eighty-one RCTs (110 induction and 71 maintenance) were identified, including 23 850 patients. About 92.3% reported clinical efficacy endpoints. The Crohn's Disease Activity Index (CDAI) dominated, defining clinical response or remission in 63.5% of trials (35 definitions of response or remission). CDAI < 150 was the commonest endpoint, but reporting reduced between periods (46.4%-41.1%), whilst use of CDAI100 increased (16.8%-30.4%). Fistula studies most commonly reported fistula closure (9, 90.0%). Reporting of biomarker, endoscopy and histology endpoints increased overall (33.3%-40.6%, 14.4%-30.4% and 3.2%-12.5%, respectively), but were heterogeneous and rarely reported in fistula trials. Patient-reported outcome measures were reported in 41.4% of trials and safety endpoints in 35.4%. Many of the common adverse events relate to disease exacerbation or treatment failure. CONCLUSIONS Trial endpoints vary across studies, over time and are distinct in fistula studies. Despite growth in reporting of objective measures of inflammation and in patient-reported outcome measures, there is a lack of standardisation. This confirms the need for a core outcome set for comparative effectiveness research in Crohn's disease.

Abstract
BACKGROUND & AIMS Fistulas are debilitating complications of Crohn's disease (CD) that affect up to 50% of patients. We conducted a systematic review and meta-analysis of randomized controlled trials to assess the efficacy of treatments for fistulizing CD. METHODS We searched publication databases from inception through December 13, 2016 for trials comparing the efficacy of a therapeutic agent (single or combination) with placebo or another active therapy in adult patients with any form of fistulizing CD. The Cochrane risk of bias tool was used to assess the methodological quality of trials; the overall quality of evidence was evaluated using GRADE. Primary outcomes included induction and maintenance of fistula response and remission. Pooled risk ratios (RRs) and 95% CIs were calculated for each outcome. RESULTS We analyzed data from 27 trials; most studies (21/27) focused on patients with perianal fistulizing CD. We found moderate-quality evidence to support the efficacy of tumor necrosis factor (TNF) antagonists (RR, 2.01; 95% CI, 1.36-2.97), particularly infliximab, ustekinumab (RR, 1.77; 95% CI, 0.93-3.37), and mesenchymal stem cell therapy (RR, 1.31; 95% CI, 0.98-1.73) for induction of fistula remission. We found low-quality evidence for the efficacy of vedolizumab and immunosuppressives. There was also low-quality evidence to support the efficacy of combination therapy with TNF antagonists and antibiotics vs a TNF antagonist alone. CONCLUSION In a systematic review and meta-analysis of 27 controlled trials, we found TNF antagonists to be effective for induction and maintenance of perianal fistula response and remission. There are few data on the effects on internal fistulae. Further studies are needed, particularly for ustekinumab, vedolizumab, and stem cell therapies, in patients with fistulizing CD.

Abstract
The incidence of inflammatory bowel disease (IBD) is increasing, and as our population ages, there is a growing number of IBD patients who are transitioning into advanced age; 15% to 20% of IBD patients are classified as late-onset (between 60-65 years of age). This has led clinicians to treat a large number of older patients with IBD. The principles of management of IBD in older patients are the same as those who are younger. There are, however, phenotypic differences that are unique to late-onset IBD and age-related concerns that clinicians must consider when initiating therapy for their older patients with IBD. Given the increasing number of older IBD patients, the aim of this article is to present an updated, evidence-based review of the therapeutic options and issues that arise in this unique patient population.

World J Gastroenterol 2017; 23:6385-6402.

Abstract
An awareness of the expected time for therapies to induce symptomatic improvement and remission is necessary for determining the timing of follow-up, disease (re)assessment, and the duration to persist with therapies, yet this is seldom reported as an outcome in clinical trials. In this review, we explore the time to clinical response and remission of current therapies for inflammatory bowel disease (IBD) as well as medication, patient and disease related factors that may influence the time to clinical response. It appears that the time to therapeutic response varies depending on the indication for therapy (Crohn's disease or ulcerative colitis). Agents with the most rapid time to clinical response included corticosteroids, calcineurin inhibitors, exclusive enteral nutrition, aminosalicylates and anti-tumor necrosis factor therapy which will work in most patients within the first 2 mo. Vedolizumab, methotrexate and thiopurines had a longer time to clinical response and can take several months to achieve maximal efficacy. Factors affecting the time to clinical response of therapies included use of concomitant therapy, disease duration, smoking status, disease phenotype and advanced age. There appears to be marked variation in time to clinical response for therapies used in IBD which is further influenced by disease and patient related factors. Understanding the expected time to therapeutic response is integral to inform further decision making, maintain a patient-centered approach and ensure treatment is given an appropriate timeframe to achieve maximal benefit prior to cessation.

Abstract
BACKGROUND The magnitude of risk of serious infections due to available medical therapies of inflammatory bowel disease (IBD) remains controversial. We conducted a systematic review and network meta-analysis of the existing IBD literature to estimate the risk of serious infection in adult IBD patients associated with available medical therapies. METHODS Studies were identified by a literature search of PubMed, Cochrane Library, Medline, Web of Science, Scopus, EMBASE, and ProQuest Dissertations and Theses. Randomized controlled trials comparing IBD medical therapies with no restrictions on language, country of origin, or publication date were included. A network meta-analysis was used to pool direct between treatment comparisons with indirect trial evidence while preserving randomization. RESULTS Thirty-nine articles fulfilled the inclusion criteria; one study was excluded from the analysis due to disconnectedness. We found no evidence of increased odds of serious infection in comparisons of the different treatment strategies against each other, including combination therapy with a biologic and immunomodulator compared to biologic monotherapy. Similar results were seen in the comparisons between the newer biologics (e.g. vedolizumab) and the anti-tumor necrosis factor agents. CONCLUSIONS No treatment strategy was found to confer a higher risk of serious infection than another, although wide confidence intervals indicate that a clinically significant difference cannot be excluded. These findings provide a better understanding of the risk of serious infection from IBD pharmacotherapy in the adult population. PROSPERO REGISTRATION The protocol for this systematic review was registered on PROSPERO ( CRD42014013497 ).

Abstract
BACKGROUND This study assessed the efficacy and safety of methotrexate (MTX) compared with thiopurines (TPs) for refractory Crohn's disease. METHODS Fifty-one consecutive patients who were refractory or intolerant to TPs and steroid-dependent were retrospectively analyzed. MTX (20 mg/wk, subcutaneous) was adopted for inducing and maintaining clinical remission (CR). Fifty-seven patients who were naive to immunosuppressant and prescribed azathioprine (2 mg·kg·d) or mercaptopurine (1 mg·kg·d) were simultaneously recruited. RESULTS By week 16, the CR rate was 68.6% and 78.9% in the MTX and TPs groups, respectively (P = 0.222). Patients with disease duration ≤3 years were more likely to achieve CR with MTX (odds ratio = 7.667, P = 0.019). By week 64, the CR rate of patients achieved remission at week 16 was 45.7% and 44.4% in the MTX and TPs groups, respectively (P = 0.910). Normalization of high-sensitivity C-reactive protein level (relative risk = 11.221, P = 0.003) and platelet count (relative risk = 9.672, P = 0.004) at week 16 predicted the efficacy of maintaining remission with MTX. Among patients with remission at week 16, the mucosal healing rates at week 36 were 47.4% with MTX and 47.1% with TPs (P ≈ 1.000). Fifteen (29.4%) patients on MTX and 25 (43.9%) on TPs experienced adverse events (P = 0.121). CONCLUSIONS MTX is effective in inducing and maintaining CR and achieving mucosal healing in patients with refractory Crohn's disease, and its efficacy is comparable to that of TPs for naive patients. The side effects of MTX were mild and tolerable.

Abstract
BACKGROUND The results from controlled clinical trials investigating the efficacy of azathioprine and 6-mercaptopurine for the treatment of active Crohn's disease have been conflicting and controversial. An updated meta-analysis was performed to assess the effectiveness of these drugs for the induction of remission in active Crohn's disease. OBJECTIVES The primary objective was to determine the efficacy and safety of azathioprine and 6-mercaptopurine for induction of remission in active Crohn's disease. SEARCH METHODS We searched MEDLINE, EMBASE and the Cochrane Library from inception to 30 October 2015. Review articles and conference proceedings were also searched to identify additional studies. SELECTION CRITERIA Randomized controlled trials (RCTs) of oral azathioprine or 6-mercaptopurine compared to placebo or active therapy involving adult patients with active Crohn's disease were selected for inclusion. DATA COLLECTION AND ANALYSIS Data were extracted by two independent observers based on the intention-to-treat principle. Outcomes of interest included: clinical remission, clinical improvement, fistula improvement or healing, steroid sparing, adverse events, withdrawals due to adverse events and serious adverse events. We calculated the pooled relative risk (RR) and 95% confidence intervals (95% CI) for each outcome. The methodological quality of included studies was evaluated using the Cochrane risk of bias tool. The overall quality of the evidence supporting each outcome was assessed using the GRADE criteria. MAIN RESULTS Thirteen RCTs (n = 1211 patients) of azathioprine and 6-mercaptopurine therapy in adult patients were identified: nine included placebo comparators and six included active comparators. The majority of included studies were rated as low risk of bias. There was no statistically significant difference in clinical remission rates between azathioprine or 6-mercaptopurine and placebo. Forty-eight per cent (95/197) of patients receiving antimetabolites achieved remission compared to 37% (68/183) of placebo patients (5 studies, 380 patients; RR 1.23, 95% CI 0.97 to 1.55). There was no statistically significant difference in clinical improvement rates between azathioprine or 6-mercaptopurine and placebo. Forty-eight per cent (107/225) of patients receiving antimetabolites achieved clinical improvement or remission compared to 36% (75/209) of placebo patients (8 studies, 434 patients; RR 1.26, 95% CI 0.98 to 1.62). There was a statistically significant difference in steroid sparing (defined as prednisone dose < 10 mg/day while maintaining remission) between azathioprine and placebo. Sixty-four per cent (47/163) of azathioprine patients were able to reduce their prednisone dose to < 10 mg/day compared to 46% (32/70) of placebo patients (RR 1.34, 95% CI 1.02 to 1.77). GRADE analyses rated the overall quality of the evidence for the outcomes clinical remission, clinical improvement and steroid sparing as moderate due to sparse data. There was no statistically significant difference in withdrawals due to adverse events or serious adverse events between antimetabolites and placebo. Ten percent of patients in the antimetabolite group withdrew due to adverse events compared to 5% of placebo patients (8 studies, 510 patients; RR 1.70, 95% CI 0.94 to 3.08). Serious adverse events were reported in 14% of patients receiving azathioprine compared to 4% of placebo patients (2 studies, 216 patients; RR 2.57, 95% CI 0.92 to 7.13). Common adverse events reported in the placebo controlled studies included: allergic reactions. leukopenia, pancreatitis and nausea. Azathioprine was significantly inferior to infliximab for induction of steroid-free clinical remission. Thirty per cent (51/170) of azathioprine patients achieved steroid-free remission compared to 44% (75/169) of infliximab patients (1 study, 339 patients; RR 0.68, 95% CI 0.51 to 0.90). The combination of azathioprine and infliximab was significantly superior to infliximab alone for induction of steroid-free clinical remission. Sixty per cent (116/194) of patients in the combined azathioprine and infliximab group achieved steroid-free remission compared to 48% (91/189) of infliximab patients (2 studies, 383 patients; RR 1.23, 95% CI 1.02 to 1.47). Azathioprine or 6-mercaptopurine therapy was found to be no better at inducing steroid free clinical remission compared to methotrexate (RR 1.13, 95% CI 0.85 to 1.49) and 5-aminosalicylate or sulfasalazine (RR 1.24, 95% CI 0.80 to 1.91). There were no statistically significant differences in withdrawals due to adverse events between azathioprine or 6-mercaptopurine and methotrexate (RR 0.78, 95% CI 0.23 to 2.71); between azathioprine or 6-mercaptopurine and 5-aminosalicylate or sulfasalazine (RR 0.98, 95% CI 0.38 to 2.54); between azathioprine and infliximab (RR 1.47, 95% CI 0.96 to 2.23); or between the combination of azathioprine and infliximab and infliximab (RR 1.16, 95% CI 0.75 to 1.80). Common adverse events in the active comparator trials included nausea, abdominal pain, pyrexia and headache. AUTHORS' CONCLUSIONS Azathioprine and 6-mercaptopurine offer no advantage over placebo for induction of remission or clinical improvement in active Crohn's disease. Antimetaboilte therapy may allow patients to reduce steroid consumption. Adverse events were more common in patients receiving antimetabolites although differences with placebo were not statistically significant. Azathioprine therapy is inferior to infliximab for induction of steroid-free remission. However, the combination of azathioprine and infliximab was superior to infliximab alone for induction of steroid-free remission.

Abstract
Methotrexate is commonly used in rheumatoid arthritis but randomised controlled trials demonstrated its efficacy also in Crohn's disease. Methotrexate, although marginally used in clinical practice, is considered an appropriate immunomodulator particularly in patients refractory or intolerant to thiopurines. Areas covered: A literature search using 'methotrexate', 'Crohn's disease' and 'Inflammatory Bowel Disease' as key words, identified randomised controlled trials, meta-analyses and observational studies. The aim of this review is to summarise and critically discuss the available evidence concerning the efficacy and safety of methotrexate in the treatment of Crohn's disease. Expert commentary: Methotrexate is effective in inducing and maintaining remission in steroid-dependent CD at a dose of 25 mg/week and 15 mg/week, respectively. Data from observational studies suggest that methotrexate may be as efficacious as thiopurines with a similar safety profile. In specific clinical settings, (patients with a history of malignancy or young Epstein-Barr Virus-seronegative patients), methotrexate compete favourably with thiopurines.

Abstract
INTRODUCTION Methotrexate (MTX) has been utilized for the treatment of Crohn's disease (CD) for decades. Nevertheless, current data provide equivocal evidence on the efficacy of MTX in CD.The aims of this study were to describe the efficacy of MTX for maintenance of remission in CD and to identify the factors associated with the probability of steroid-free clinical remission in a multicenter European referral center cohort. PATIENTS AND METHODS This was a retrospective cohort analysis. Consecutive patients treated with MTX for CD were included from 11 referral centers. Patients receiving concomitant treatment with tumor necrosis factor inhibitors or thiopurines were excluded. The main outcome was steroid-free clinical remission; the secondary outcomes included the rate of complications leading to MTX discontinuation and duration of relapse-free survival in patients achieving the main outcome. RESULTS Between July 1992 and January 2012, 118 patients were identified for inclusion. MTX administration route was oral for induction in 31.4% and for maintenance in 49.1% of the patients. Steroid-free remission was achieved in 44/118 (37.2%) patients and was maintained relapse free by 28/44 (63.6%) for a median of 12 (3.5-18.5) months. At least one adverse effect was reported by 28.9% of the patients. No clinical or demographic factors were associated with either likelihood of achieving a clinical response or duration of relapse-free survival. CONCLUSION MTX treatment induced steroid-free clinical remission in over a third of CD patients and maintained it for a year in almost two-thirds of the responders. MTX should be considered a viable therapeutic option in CD patients refractory to other therapies.

Abstract
Low-dose methotrexate (MTX) therapy is a well-recognized therapy for many inflammatory conditions such as rheumatoid arthritis, psoriatic arthritis, and psoriasis. More than 20 years ago, the clinical efficacy of MTX was also established for steroid dependent Crohn's disease, but it was never broadly adapted as a treatment modality. More recently, MTX is being increasingly used in the pediatric population with Crohn's disease, both as a single agent as well as a concomitant therapy with anti-tumor necrosis factor-alpha treatment. This review outlines important pharmacological aspects for the therapeutic application of MTX and the current status of MTX as mono- or combination-therapy in both pediatric and adult patients with inflammatory bowel disease including new results of MTX monotherapy in steroid dependent ulcerative colitis.

Abstract
Although multiple innovative treatments of inflammatory bowel disease have become available, research continues to refine the value of existing drug therapies for Crohn's disease and ulcerative colitis. What can Cochrane reviews tell us about evolving applications for traditional agents in inflammatory bowel disease? A Cochrane Collaboration symposium held at the 2014 Digestive Diseases Week annual meeting addressed this question. This article reviews the data presented at that session.

Abstract
Objective.Evolving inflammatory bowel disease (IBD) is a matter of interest in patients with juvenile idiopathic arthritis (JIA) and might be associated with JIA therapy.Methods.Data from the German biologics registry (Biologika in der Kinderrheumatologie; BiKeR) from 2001 to 2013 were analyzed.Results.There were 3071 patients with 8389 patient-years (PY) of observation followed. IBD was diagnosed in 11 patients, 8 with Crohn disease and 3 with ulcerative colitis. IBD incidence in patients with JIA was 1.31/1000 PY and higher than published IBD incidences in pediatric populations. Compared with the total BiKeR cohort, patients with IBD more commonly had enthesitis-related arthritis, extended oligoarthritis, psoriatic arthritis, and also rheumatoid factor (RF)-negative polyarthritis. No IBD occurred in patients with systemic JIA or RF-positive polyarthritis. In patients treated with methotrexate (MTX), the IBD incidence was significantly lower compared with patients not treated with MTX. Etanercept (ETN) monotherapy, but not the combination of ETN and MTX, was associated with an increased incidence of IBD.Conclusion.Incidence of IBD in patients with JIA is higher than in the population. MTX turned out to be protective, even in combination with ETN.

Abstract
Although corticosteroids are an effective treatment for induction of remission in inflammatory bowel disease (IBD), many patients are dependent on or refractory to corticosteroids. This review is based on scrutinizing current literature with emphasis on randomized controlled trials, meta-analyses, and Cochrane reviews on the management of IBD refractory to corticosteroids. Based on this evidence, we propose algorithms and optimization strategies for use of immunomodulator and biologic therapy in IBD refractory to corticosteroids.

Abstract
BACKGROUND & AIMS There is controversy regarding the best treatment for patients with Crohn's disease because of the lack of direct comparative trials. We compared therapies for induction and maintenance of remission in patients with Crohn's disease, based on direct and indirect evidence. METHODS We performed systematic reviews of MEDLINE, EMBASE, and Cochrane Central databases, through June 2014. We identified randomized controlled trials (N = 39) comparing methotrexate, azathioprine/6-mercaptopurine, infliximab, adalimumab, certolizumab, vedolizumab, or combined therapies with placebo or an active agent for induction and maintenance of remission in adult patients with Crohn's disease. Pairwise treatment effects were estimated through a Bayesian random-effects network meta-analysis and reported as odds ratios (OR) with a 95% credible interval (CrI). RESULTS Infliximab, the combination of infliximab and azathioprine (infliximab + azathioprine), adalimumab, and vedolizumab were superior to placebo for induction of remission. In pair-wise comparisons of anti-tumor necrosis factor agents, infliximab + azathioprine (OR, 3.1; 95% CrI, 1.4-7.7) and adalimumab (OR, 2.1; 95% CrI, 1.0-4.6) were superior to certolizumab for induction of remission. All treatments were superior to placebo for maintaining remission, except for the combination of infliximab and methotrexate. Adalimumab, infliximab, and infliximab + azathioprine were superior to azathioprine/6-mercaptopurine: adalimumab (OR, 2.9; 95% CrI, 1.6-5.1), infliximab (OR, 1.6; 95% CrI, 1.0-2.5), infliximab + azathioprine (OR, 3.0; 95% CrI, 1.7-5.5) for maintenance of remission. Adalimumab and infliximab + azathioprine were superior to certolizumab: adalimumab (OR, 2.5; 95% CrI, 1.4-4.6) and infliximab + azathioprine (OR, 2.6; 95% CrI, 1.3-6.0). Adalimumab was superior to vedolizumab (OR, 2.4; 95% CrI, 1.2-4.6). CONCLUSIONS Based on a network meta-analysis, adalimumab and infliximab + azathioprine are the most effective therapies for induction and maintenance of remission of Crohn's disease.

Abstract
Methotrexate is an immunosuppressant that may be useful in several clinical scenarios in inflammatory bowel disease. In this article, we review the available evidence in Crohn's disease and ulcerative colitis and establish general recommendations for its use in clinical practice. Although the available data are limited, it is very likely that methotrexate is underused because its effectiveness is underestimated and its toxicity is overestimated. Both in induction therapy and in maintenance of remission, methotrexate is useful in Crohn's disease. When prescribed in combination with biologic agents, immunogenicity is less frequent and consequently long-term response could potentially be improved. There are few published studies, but several data suggest that methotrexate could also be useful in ulcerative colitis. Although myelotoxicity and liver toxicity are well known risks, methotrexate is a drug that is well tolerated in many patients, even in the long term.

Abstract
BACKGROUND Safe and effective long-term treatments that reduce the need for corticosteroids are needed for Crohn's disease. Although purine antimetabolites are moderately effective for maintenance of remission patients often relapse despite treatment with these agents. Methotrexate may provide a safe and effective alternative to more expensive maintenance treatment with TNF-α antagonists. This review is an update of a previously published Cochrane review. OBJECTIVES To conduct a systematic review of randomized trials examining the efficacy and safety of methotrexate for maintenance of remission in Crohn's disease. SEARCH METHODS The Cochrane Central Register of Controlled Trials (CENTRAL), PUBMED, EMBASE, and the Cochrane IBD/FBD Group Specialized Trials Register were searched from inception to June 9, 2014. Study references and review papers were also searched for additional trials. SELECTION CRITERIA Randomised controlled trials (RCTs) that compared methotrexate to placebo or any other active intervention for maintenance of remission in Crohn's disease were eligible for inclusion. DATA COLLECTION AND ANALYSIS Two authors independently reviewed studies for eligibility, extracted data and assessed study quality using the Cochrane risk of bias tool. The primary outcome measure was the proportion of patients maintaining clinical remission as defined by the studies and expressed as a percentage of the total number of patients randomized (intention-to-treat analysis). We calculated the pooled risk ratio (RR) and corresponding 95% confidence intervals (95% CI) for dichotomous outcomes. The overall quality of the evidence supporting the primary outcome was assessed using the GRADE criteria. MAIN RESULTS Five studies (n = 333 patients) were included in the review. Three studies were judged to be at low risk of bias. Two studies were judged to be at high risk of bias due to blinding. Intramuscular methotrexate was superior to placebo for maintenance of remission at 40 weeks follow-up. Sixty-five per cent of patients in the intramuscular methotrexate group maintained remission compared to 39% of placebo patients (RR 1.67, 95% CI 1.05 to 2.67; 76 patients).The number needed to treat to prevent one relapse was four. A GRADE analysis indicated that the overall quality of evidence supporting this outcome was moderate due to sparse data (40 events). There was no statistically significant difference in maintenance of remission at 36 weeks follow-up between oral methotrexate (12.5 mg/week) and placebo. Ninety per cent of patients in the oral methotrexate group maintained remission compared to 67% of placebo patients (RR 1.67, 95% CI 1.05 to 2.67; 22 patients). A GRADE analysis indicated that the overall quality of evidence supporting this outcome was low due to very sparse data (17 events). A pooled analysis of two small studies (n = 50) showed no statistically significant difference in continued remission between oral methotrexate (12.5 mg to 15 mg/week) and 6-mercaptopurine (1 mg/kg/day) for maintenance of remission. Seventy-seven per cent of methotrexate patients maintained remission compared to 57% of 6-mercaptopurine patients (RR 1.36, 95% CI 0.92 to 2.00). A GRADE analysis indicated that the overall quality of evidence supporting this outcome was very low due to high risk of bias in one study (no blinding) and very sparse data (33 events). One small (13 patients) poor quality study found no difference in continued remission between methotrexate and 5-aminosalicylic acid (RR 2.62, 95% CI 0.23 to 29.79). A pooled analysis of two studies (n = 145) including one high quality trial (n = 126) found no statistically significant difference in maintenance of remission at 36 to 48 weeks between combination therapy (methotrexate and infliximab) and infliximab monotherapy. Fifty-four percent of patients in the combination therapy group maintained remission compared to 53% of monotherapy patients (RR 1.02, 95% CI 0.76 to 1.38, P = 0.95). A GRADE analysis indicated that the overall quality of evidence supporting this outcome was low due to high risk of bias in one study (no blinding) and sparse data (78 events). Adverse events were generally mild in nature and resolved upon discontinuation or with folic acid supplementation. Common adverse events included nausea and vomiting, symptoms of a cold, abdominal pain, headache, joint pain or arthralgia, and fatigue. AUTHORS' CONCLUSIONS Moderate quality evidence indicates that intramuscular methotrexate at a dose of 15 mg/week is superior to placebo for maintenance of remission in Crohn's disease. Intramuscular methotrexate appears to be safe. Low dose oral methotrexate (12.5 to 15 mg/week) does not appear to be effective for maintenance of remission in Crohn's disease. Combination therapy (methotrexate and infliximab) does not appear to be any more effective for maintenance of remission than infliximab monotherapy. The results for efficacy outcomes between methotrexate and 6-mercaptopurine and methotrexate and 5-aminosalicylic acid were uncertain. Large-scale studies of methotrexate given orally at higher doses for maintenance of remission in Crohn's disease may provide stronger evidence for the use of methotrexate in this manner.

Abstract
Methotrexate has been used an immunomodulator in many autoimmune diseases, including inflammatory bowel disease. However, many physicians are unfamiliar or uncomfortable with its use in the management of inflammatory bowel disease. We summarize the data for use of methotrexate in common clinical scenarios: (1) steroid dependant Crohn’s disease (CD); (2) maintenance of remission in steroid free CD; (3) azathioprine failures in CD; (4) in combination therapy with Anti-TNF agents in CD; (5) decreasing antibody formation to Anti-TNF therapy in CD; (6) management of fistulizing disease in CD; and (7) as well as induction and maintenance of remission in ulcerative colitis. An easy to use algorithm is provided for the busy clinician to access and safely prescribe methotrexate for their inflammatory bowel disease patients.

Abstract
BACKGROUND Although corticosteroids are effective for induction of remission of Crohn's disease, many patients relapse when steroids are withdrawn or become steroid dependent. Furthermore, corticosteroids exhibit significant adverse effects. The success of methotrexate as a treatment for rheumatoid arthritis led to its evaluation in patients with refractory Crohn's disease. Methotrexate has been studied for induction of remission of refractory Crohn's disease and has become the principal alternative to azathioprine or 6-mercaptopurine therapy. This systematic review is an update of previously published Cochrane reviews. OBJECTIVES The primary objective was to assess the efficacy and safety of methotrexate for induction of remission in patients with active Crohn's disease in the presence or absence of concomitant steroid therapy. SEARCH METHODS We searched MEDLINE, EMBASE, CENTRAL and the Cochrane IBD/FBD group specialized register from inception to June 9, 2014 for relevant studies. Conference proceedings and reference lists were also searched to identify additional studies. SELECTION CRITERIA Randomized controlled trials of methotrexate compared to placebo or an active comparator for treatment of active refractory Crohn's disease in adult patients (> 17 years) were considered for inclusion. DATA COLLECTION AND ANALYSIS The primary outcome was failure to enter remission and withdraw from steroids. Secondary outcomes included adverse events, withdrawal due to adverse events, serious adverse events and quality of life. We calculated the relative risk (RR) and 95% confidence intervals (95% CI) for each outcome. Data were analyzed on an intention-to-treat basis. The Cochrane risk of bias tool was used to assess the methodological quality of included studies. The GRADE approach was used to assess the overall quality of evidence supporting the primary outcome. MAIN RESULTS Seven studies (495 patients) were included. Four studies were rated as low risk of bias. Three studies were rated as high risk of bias due to open label or single-blind designs. The seven studies differed with respect to participants, intervention, and outcomes to the extent that meta-analysis was considered to be inappropriate. GRADE analyses indicated that the quality of evidence was very low to low for most outcomes due to sparse data and inadequate blinding. Three small studies which employed low dose oral methotrexate showed no statistically significant difference in failure to induce remission between methotrexate and placebo or between methotrexate and 6-mercaptopurine. For the study using 15 mg/week of oral methotrexate 33% (5/15) of methotrexate patients failed to enter remission compared to 11% (2/18) of placebo patients (RR 3.00, 95% CI 0.68 to 13.31). For the study using 12.5 mg/week of oral methotrexate 81% (21/26) of methotrexate patients failed to enter remission compared to 77% (20/26) of placebo patients (RR 1.05, 95% CI 0.79 to 1.39). This study also had an active comparator arm, 81% (21/26) of methotrexate patients failed to enter remission compared to 59% (19/32) of 6-mercaptopurine patients (RR 1.36, 95% CI 0.97 to 1.92). For the active comparator study using 15 mg/week oral methotrexate, 20% (3/15) of methotrexate patients failed to enter remission compared to 6% of 6-mercaptopurine patients (RR 3.20, 95% CI 0.37 to 27.49). This study also had a 5-ASA arm and found that methotrexate patients were significantly more likely to enter remission than 5-ASA patients. Twenty per cent (3/15) of methotrexate patients failed to enter remission compared to 86% (6/7) of 5-ASA patients (RR 0.23, 95% CI 0.08 to 0.67). One small study which used a higher dose of intravenous or oral methotrexate (25 mg/week) showed no statistically significant difference between methotrexate and azathioprine. Forty-four per cent (12/27) of methotrexate patients failed to enter remission compared to 37% of azathioprine patients (RR 1.20, 95% CI 0.63 to 2.29). Two studies found no statistically significant difference in failure to enter remission between the combination of infliximab and methotrexate and infliximab monotherapy. One small study utilized intravenous methotrexate (20 mg/week) for 5 weeks and then switched to oral (20 mg/week). Forty-five per cent (5/11) of patients in the combination group failed to enter remission compared to 62% of infliximab patients (RR 0.73, 95% CI 0.31 to 1.69). The other study assessing combination therapy utilized subcutaneous methotrexate (maximum dose 25 mg/week). Twenty-four per cent (15/63) of patients in the combination group failed to enter remission compared to 22% (14/63) of infliximab patients (RR 1.07, 95% CI 0.57 to 2.03). A large placebo-controlled study which employed a high dose of methotrexate intramuscularly showed a statistically significant benefit relative to placebo. Sixty-one per cent of methotrexate patients failed to enter remission compared to 81% of placebo patients (RR 0.75, 95% CI 0.61 to 0.93; number needed to treat, NNT=5). Withdrawals due to adverse events were significantly more common in methotrexate patients than placebo in this study. Seventeen per cent of methotrexate patients withdrew due to adverse events compared to 2% of placebo patients (RR 8.00, 95% CI 1.09 to 58.51). The incidence of adverse events was significantly more common in methotrexate patients (63%, 17/27) than azathioprine patients (26%, 7/27) in one small study (RR 2.42, 95% CI 1.21 to 4.89). No other statistically significant differences in adverse events, withdrawals due to adverse events or serious adverse events were reported in any of the other placebo-controlled or active comparator studies. Common adverse events included nausea and vomiting, abdominal pain, diarrhea, skin rash and headache. AUTHORS' CONCLUSIONS There is evidence from a single large randomized trial which suggests that intramuscular methotrexate (25 mg/week) provides a benefit for induction of remission and complete withdrawal from steroids in patients with refractory Crohn's disease. Lower dose oral methotrexate does not appear to provide any significant benefit relative to placebo or active comparator. However, these trials were small and further studies of oral methotrexate may be justified. Comparative studies of methotrexate to drugs such as azathioprine or 6-mercaptopurine would require the randomization of large numbers of patients. The addition of methotrexate to infliximab therapy does not appear to provide any additional benefit over infliximab monotherapy. However these studies were relatively small and further research is needed to determine the role of methotrexate when used in conjunction with infliximab or other biological therapies.

Abstract
The inflammatory bowel diseases (IBDs) are chronic incurable conditions that primarily present in young patients. Being incurable, the IBDs may be part of the patient’s life for many years and these conditions require therapies that will be effective over the long-term. Surgery in Crohn’s disease does not cure the disease with endoscopic recurrent in up to 70% of patients 1 year post resection. This means that, the patient will require many years of medications and the goal of the treating physician is to induce and maintain long-term remission without side effects. The development of the anti-tumour necrosis factor alpha (TNFα) agents has been a magnificent clinical advance in IBD, but they are not always effective, with loss of response overtime and, at times, discontinuation is required secondary to side effects. So what options are available if of the anti-TNFα agents can no longer be used? This review aims to provide other options for the physician, to remind them of the older established medications like azathioprine/6-mercaptopurine and methotrexate, the less established medications like mycophenolate mofetil and tacrolimus as well as newer therapeutic options like the anti-integins, which block the trafficking of leukocytes into the intestinal mucosa. The location of the intestinal inflammation must also be considered, as topical therapeutic agents may also be worthwhile to consider in the long-term management of the more challenging IBD patient. The more options that are available the more likely the patient will be able to have tailored therapy to treat their disease and a better long-term outcome.

Abstract
BACKGROUND The incidence of obesity is increasing worldwide. Recent evidence shows that the incidence of Crohn's disease (CD) is increasing as well. Adipocytes release a variety of proinflammatory cytokines and peptides. Visceral adiposity may play an important role in the initiation and perpetuation of inflammation in CD. We report on an analysis of body weight in CD clinical trials between 1991 and 2008. METHODS MEDLINE-based databases were searched for randomized controlled trials pertaining to CD. A time-trend analysis was carried out to investigate changes in weight and disease activity over time. Potential correlation between subject weight and clinical activity was studied. RESULTS Forty randomized controlled trials involving a total of 10,282 patients with CD conducted between 1991 and 2008 were included. No significant change in gender distribution was noted throughout the follow-up. A significant increase in weight (r = 0.360; 95% confidence interval [CI]: 0.4556-0.8813) and body mass index (r = 0.1431; 95% CI: 0.02628-0.2272) was observed over the time period. Study subjects demonstrated a significant increase in clinical disease activity as measured by the Crohn's disease activity index (r = 0.1092; 95% CI: 2.101-9.087) and disease duration (r = 0.06340; 95% CI: 0.02421-0.2530) over the same time period. CONCLUSIONS We demonstrate increasing body weight over time from 1991 to 2008 in CD as evidenced by baseline data from randomized clinical trials. Adiposity may play a potential role in initiating and perpetuating intestinal inflammation, a hypothesis that should be explored further.
