Abstract
BACKGROUND Inflammatory bowel disease [IBD] is associated with an increased risk of developing lymphoma. Although recent data have clarified the epidemiology of lymphoma in IBD patients, the clinical and pathological characteristics of lymphoma in IBD remain poorly known. METHODS Patients with IBD and lymphoma were retrospectively identified in the framework of a national collaborative study including the Groupe d'Étude Thérapeutique des Affections Inflammatoires du Tube Digestif [GETAID] and the Lymphoma Study Association [LYSA]. We characterized clinical and prognostic features for the three most frequent lymphoma subtypes occurring in IBD. We performed a multicentre case-control study. Controls [lymphoma de novo] were matched [5:1] to cases on gender, age at diagnosis, lymphoma subtype, year of diagnosis, and IPI/FLIPI indexes. Overall survival and progression-free survival were compared between cases and controls. RESULTS In total, 133 IBD patients with lymphoma were included [males = 62.4%, median age at lymphoma diagnosis = 49 years in males; 42 years in females]. Most had Crohn's disease [73.7%] and were exposed to thiopurines [59.4%]. The most frequent lymphoma subtypes were diffuse large B cell lymphoma [DLBCL, 45.1%], Hodgkin lymphoma [HL, 18.8%], and follicular lymphoma [FL, 10.5%]. When matched with 365 controls, prognosis was improved in IBD patients with DLBCL compared to controls [p = 0.0064, hazard ratio = 0.36] or similar [HL and FL]. CONCLUSIONS Lymphomas occurring in IBD patients do not seem to have a worse outcome than in patients without IBD. Due to the rarity of this situation, such patients should be managed in expert centres.

The universal effects of low-dose interleukin-2 across 13 autoimmune diseases in a basket clinical trial. J Autoimmun 2024; 144:103172. [PMID: 38330545 DOI: 10.1016/j.jaut.2024.103172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 01/15/2024] [Accepted: 01/25/2024] [Indexed: 02/10/2024]
Abstract
BACKGROUND A Tregs insufficiency is central to autoimmune and inflammatory diseases pathophysiology and low dose interleukin-2 (IL-2LD) can specifically activate Tregs. OBJECTIVE To assess IL-2LD therapeutic potential and select diseases for further clinical development, we performed an open-label, phase 2a, disease-finding, "basket trial" involving patients with one of 13 different autoimmune diseases. METHODS 81 patients treated with IL-2LD (1 million IU/day) for 5 days, followed by fortnightly injections. The first 48 patients received diluted Proleukin®, while the subsequent 33 received ready-to-use ILT-101®. The primary endpoint was the change in Tregs at day-8 compared to baseline. Key secondary endpoints included clinical efficacy assessments using the Clinical Global Impression (CGI) scale, disease-specific scores, and EuroQL-5D-5L. RESULTS Our study unveiled a universal and significant expansion and activation of Tregs, without concomitant Teffs activation, across all 13 autoimmune diseases. Both Proleukin® and ready-to-use ILT-101® demonstrated identical effects on Tregs. CGI scores reflecting activity, severity, and efficacy were significantly reduced in the overall patient population. Disease-specific clinical scores improved in five of the six disease cohorts with at least six patients, namely ankylosing spondylitis, systemic lupus erythematosus, Behçet's disease, Sjögren's syndrome, and systemic sclerosis. Urticaria was the only severe adverse event related to treatment. CONCLUSION IL-2LD was well-tolerated, exhibiting specific Treg activation and clinical improvements across the 13 autoimmune diseases. CLINICAL IMPLICATION Tregs stimulation by IL-2LD is a promising therapeutic strategy and IL-2LD holds considerable promise for integration into combinatorial therapeutic approaches.

Dynamic Prediction of Advanced Colorectal Neoplasia in Inflammatory Bowel Disease. Clin Gastroenterol Hepatol 2024:S1542-3565(24)00214-3. [PMID: 38431223 DOI: 10.1016/j.cgh.2024.02.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 01/31/2024] [Accepted: 02/03/2024] [Indexed: 03/05/2024]
Abstract
BACKGROUND & AIMS Colonoscopic surveillance is recommended in patients with colonic inflammatory bowel disease (IBD) given their increased risk of colorectal cancer (CRC). We aimed to develop and validate a dynamic prediction model for the occurrence of advanced colorectal neoplasia (aCRN, including high-grade dysplasia and CRC) in IBD. METHODS We pooled data from 6 existing cohort studies from Canada, The Netherlands, the United Kingdom, and the United States. Patients with IBD and an indication for CRC surveillance were included if they underwent at least 1 follow-up procedure. Exclusion criteria included prior aCRN, prior colectomy, or an unclear indication for surveillance. Predictor variables were selected based on the literature. A dynamic prediction model was developed using a landmarking approach based on Cox proportional hazard modeling. Model performance was assessed with Harrell's concordance-statistic (discrimination) and by calibration curves. Generalizability across surveillance cohorts was evaluated by internal-external cross-validation. RESULTS The surveillance cohorts comprised 3731 patients, enrolled and followed-up in the time period from 1973 to 2021, with a median follow-up period of 5.7 years (26,336 patient-years of follow-up evaluation); 146 individuals were diagnosed with aCRN. The model contained 8 predictors, with a cross-validation median concordance statistic of 0.74 and 0.75 for a 5- and 10-year prediction window, respectively. Calibration plots showed good calibration. Internal-external cross-validation results showed medium discrimination and reasonable to good calibration. CONCLUSIONS The new prediction model showed good discrimination and calibration, however, generalizability results varied. Future research should focus on formal external validation and relate predicted aCRN risks to surveillance intervals before clinical application.

Tumor Necrosis Factor Inhibitors in Inflammatory Bowel Disease and Risk of Immune Mediated Inflammatory Diseases. Clin Gastroenterol Hepatol 2024; 22:135-143.e8. [PMID: 37442315 DOI: 10.1016/j.cgh.2023.06.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 05/18/2023] [Accepted: 06/29/2023] [Indexed: 07/15/2023]
Abstract
BACKGROUND & AIMS Tumor necrosis factor inhibitors (anti-TNF) are effective therapies for several immune-mediated inflammatory diseases (IMIDs). However, case reports have identified the paradoxical occurrence of IMIDs in patients treated with anti-TNF. We studied the risk of rheumatoid arthritis, psoriasis, and hidradenitis suppurativa after the initiation of anti-TNF therapy for inflammatory bowel disease (IBD). METHODS We conducted 2 nationwide cohort studies comprising all patients with IBD in Denmark (2005-2018) and France (2008-2018). We obtained individual-level information on exposure to anti-TNF, diagnoses of IMIDs including rheumatoid arthritis, psoriasis, and hidradenitis suppurativa, and potential confounders from healthcare registers in the respective countries. We used Cox models to estimate hazard ratios (HRs) for the association between anti-TNF exposure and IMIDs and then pooled the estimates from the 2 cohorts. To test the robustness of our results, we performed an active comparator analysis of anti-TNF monotherapy vs azathioprine monotherapy. RESULTS The Danish and French cohorts comprised 18,258 and 88,786 subjects with IBD, respectively, contributing a total of 516,055 person-years of follow-up. Anti-TNF was associated with an increased risk of rheumatoid arthritis, psoriasis, and hidradenitis suppurativa in both the Danish (HR, 1.66; 95% confidence interval [CI], 1.34-2.07) and the French cohort (HR, 1.78; 95% CI, 1.63-1.94), with a pooled HR of 1.76 (95% CI, 1.63-1.91). Anti-TNF was also associated with an increased risk of the outcomes when compared with azathioprine (pooled HR, 2.94; 95% CI, 2.33-3.70). CONCLUSIONS In 2 nationwide cohorts of IBD patients, anti-TNF therapy was associated with an increased risk of rheumatoid arthritis, psoriasis, and hidradenitis suppurativa.

Focal loss of mural stratification as a radiological predictor for small bowel adenocarcinoma in Crohn's disease. Clin Res Hepatol Gastroenterol 2023; 47:102246. [PMID: 37967612 DOI: 10.1016/j.clinre.2023.102246] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 11/10/2023] [Accepted: 11/11/2023] [Indexed: 11/17/2023]
Abstract
AIM Patients with Crohn's disease (CD) are at higher risk of small bowel adenocarcinoma (SBA). We aimed to identify radiological predictors of SBA in CD. METHODS We conducted a retrospective case-control study at two tertiary inflammatory bowel disease centers and identified CD patients diagnosed with SBA between 2003 and 2019. Patients were matched with up to four controls. Pre-operative imaging (magnetic resonance imaging (MRI) or computed tomography (CT)) were reviewed by three gastrointestinal radiologists. RESULTS Nineteen patients with CD-associated SBA with a mean age of 54.9 and 32 matched controls were included. Mean length of small bowel involvement was 216 (± 188) mm in the SBA group versus 156 (± 167) mm in the control group (p = 0.76). Only 11.8 % of cases had a diagnosis of SBA made preoperatively. In univariate analysis, focal loss of mural stratification (odds ratio [OR], 11; 95%CI, 2.43-49.5, p = 0.002), and wall thickening (OR, 1.32; 95%CI, 1.05-1.66, p = 0.02) were significantly associated with SBA. After adjustment, focal loss of mural stratification was the only independent risk factor (OR, 11; 95 % CI, 2.43-49.5, p = 0.002). CONCLUSIONS Focal loss of mural stratification was identified as a predictor of CD-associated SBA, which should be described in imaging reports and further validated.

Patient and Public Involvement in Research: Lessons for Inflammatory Bowel Disease. J Crohns Colitis 2023; 17:1882-1891.

Abstract
Participatory research, also referred to as patient and public involvement, is an approach that involves collaborating with patients affected by the focus of the research, on the design, development and delivery of research to improve outcomes. There are two broad justifications for this: first, that it enhances the quality and relevance of research, and second, that it satisfies the ethical argument for patient inclusion in decisions about them. This synergistic and collaborative effort, which bridges the divide between researchers and participants with the lived condition, is now a mainstream activity and widely accepted as best practice. Although there has been a substantial increase in the literature over the past two decades, little has been published on how participatory research has been used in inflammatory bowel disease [IBD] research and little guidance as to how researchers should go about this. With an increasing incidence and prevalence worldwide, combined with declining study enrolment in an era of perennial unmet need, there are a multitude of benefits of participatory research to IBD patients and investigators, including research output that is informed and relevant to the real world. A key example of participatory research in IBD is the I-CARE study, a large-scale, pan-European observational study assessing the safety of advanced therapies, which had significant patient involvement throughout the study. In this review, we provide a comprehensive overview of the benefits and challenges of participatory research and discuss opportunities of building strategic alliances between IBD patients, healthcare providers and academics to strengthen research outcomes.

Psychometric validation of the French Multidimensional Chronic Asthenia Scale (MCAS) in a sample of 621 patients with chronic fatigue. BMC Psychol 2023; 11:324. [PMID: 37817287 PMCID: PMC10566142 DOI: 10.1186/s40359-023-01358-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Accepted: 09/28/2023] [Indexed: 10/12/2023] Open
Abstract
BACKGROUND Psychometric validation of the Multidimensional Chronic Asthenia Scale (MCAS) was conducted in order to provide an effective tool for assessing the health-related quality of life of French-speaking patients with chronic asthenia (CA). METHODS Items resulting from the initial formulation of the self-reported MCAS (along with other materials) were completed by French-speaking volunteers with inactive or active inflammatory bowel disease (IBD-I vs. IBD-A) or chronic fatigue syndrome (CFS). Responses from 621 participants (180 patients with IBD-A, 172 with IBD-I, 269 with CFS) collected in a single online survey were divided into three subsamples to test the construct validity of the MCAS (Step 1, N = 240), to confirm its factorial structure (Step 2, N = 204) and to explore its convergent-discriminant validity with the Fatigue Symptoms Inventory (FSI) and revised Piper Fatigue Scale (r-PFS, Step 3, N = 177). RESULTS Steps 1 and 2 showed that, as expected, MCAS has four dimensions: feeling of constraint (FoC), physical (PC), life (LC) and interpersonal consequences (IC), which are also related to the duration of CA (i.e., the longer it lasts, the more the dimensions are impacted). The results further showed that the MCAS is sensitive enough to capture between-group differences, with the CFS group being the most impaired, followed by IBD-A and IBD-I. While convergent-discriminant validity between the 4 factors of MCAS and FSI and r-PFS, respectively, was satisfactory overall, Step 3 also pointed to some limitations that call for future research (e.g., shared variances between the PC and IC dimensions of MCAS and behavioral dimension of r-PFS). CONCLUSION Despite these limitations, the MCAS clearly constitutes a promising tool for measuring quantitative differences (i.e., severity/intensity) in CA associated with various diseases, but also, and importantly, the clinically important differences in domains of its expression (i.e., qualitative differences).

Risk of colorectal neoplasia according to histologic disease activity in patients with inflammatory bowel disease and colonic post-inflammatory polyps. Aliment Pharmacol Ther 2023; 57:1445-1452.

Abstract
BACKGROUND AND AIMS While post-inflammatory polyps (PIPs) have historically been a risk factor for colorectal neoplasia (CRN), histologic activity may explain this association. We aimed to assess the impact of histologic activity on CRN occurrence in IBD patients with colonic PIPs. METHODS Patients with PIPs on surveillance colonoscopy at Saint-Antoine hospital between 1 January 1996 and 31 December 2020 were included and subsequent colonoscopies were assessed. Histologic IBD activity was assessed by the Nancy histologic index. Survival and Cox regression analysis were performed to assess the strength of the association of PIPs and other patient variables with progression to CRN. RESULTS A total of 173 patients with at least two surveillance colonoscopies with PIPs at index colonoscopy were compared to a similar group of 252 patients without PIPs. In survival analysis, the presence or PIPs at index colonoscopy did not impact the risk of CRN in patients with histological inflammation (p = 0.83) and in patients without histological inflammation (p = 0.98). The risk of CRN was associated with increasing Nancy index score of 3 or 4 (HR: 4.16; 95% CI 1.50-11.52 and HR: 3.44; 95% CI 1.63-7.24), age (HR per 10-year increase: 1.37; 95% CI 1.13-1.66) and first-degree family history of colorectal cancer (HR: 5.87; v 1.31-26.26), but not PIPs (HR: 1.17; 95% CI 0.63-2.17). CONCLUSIONS After controlling for histologic activity, PIPs do not increase the risk of CRN in IBD patients. Histologic activity rather than PIPs should be considered in the risk assessment of CRN.

Abstract
BACKGROUND AND AIMS There is a need to evaluate the benefit-risk ratio of current therapies in inflammatory bowel disease (IBD) patients to provide the best quality of care. The primary objective of I-CARE (IBD Cancer and serious infections in Europe) was to assess prospectively safety concerns in IBD, with specific focus on the risk of cancer/lymphoma and serious infections in patients treated with anti-tumor necrosis factor and other biologic monotherapy as well as in combination with immunomodulators. METHODS I-CARE was designed as a European prospective longitudinal observational multicenter cohort study to include patients with a diagnosis of Crohn's disease, ulcerative colitis, or IBD unclassified established at least 3 months prior to enrollment. RESULTS A total of 10,206 patients were enrolled between March 2016 and April 2019, including 6169 (60.4%) patients with Crohn's disease, 3853 (37.8%) with ulcerative colitis, and 184 (1.8%) with a diagnosis of IBD unclassified. Thirty-two percent of patients were receiving azathioprine/thiopurines, 4.6% 6-mercaptopurine, and 3.2% methotrexate at study entry. At inclusion, 47.3% of patients were treated with an anti-tumor necrosis factor agent, 8.8% with vedolizumab, and 3.4% with ustekinumab. Roughly one-quarter of patients (26.8%) underwent prior IBD-related surgery. Sixty-six percent of patients had been previously treated with systemic steroids. Three percent of patients had a medical history of cancer prior to inclusion and 1.1% had a history of colonic, esophageal, or uterine cervix high-grade dysplasia. CONCLUSIONS I-CARE is an ongoing investigator-initiated observational European prospective cohort study that will provide unique information on the long-term benefits and risks of biological therapies in IBD patients. (EudraCT, Number: 2014-004728-23; ClinicalTrials.gov, Number: NCT02377258).

Abstract
BACKGROUND AND AIMS There are concerns regarding the potential impact of the COVID-19 outbreak on patients with inflammatory bowel disease [IBD]. We report on the impact of the COVID-19 outbreak in a European prospective cohort study of patients with IBD. PATIENTS AND METHODS We prospectively collected data from 5457 patients with IBD nested in the ongoing I-CARE project and still followed up in April 2020, with monthly online monitoring of clinical activity, treatment, imaging and endoscopy. Investigators were also contacted to report incidental cases. RESULTS In total, 233 [4.3%] reported COVID-19 and 12 [0.2%] severe COVID-19, with no COVID-19 deaths. The risk of COVID-19 in patients with IBD was not increased compared to the general population (standardized incidence ratio [SIR]: 1.18, 95% confidence interval [CI] [1.03-1.34], p = 0.009), as well as the risk of severe COVID-19 (SIR: 0.69, 95% CI [0.35-1.20], p = 0.93). We did not observe any negative impact of the different IBD-related medication on the risk of either COVID-19 or severe COVID-19. In 2020, the COVID-19 outbreak resulted in a drastic decrease in endoscopic and imaging procedures from March to May 2020 compared to 2018 and 2019. No impacts on clinical IBD disease activity as well as ongoing treatment were noted. CONCLUSION No increases in either COVID-19 or severe COVID-19 incidences were observed in patients with IBD. There was no impact of COVID-19 on IBD-related medication and clinical activity. Access to endoscopy and imaging was restricted during the first months of the first COVID-19 outbreak.

Abstract
BACKGROUND & AIMS Patients with inflammatory bowel disease (IBD) are at increased risk of acute arterial events. Treatment with anti-tumor necrosis factor (anti-TNF) agents has been associated with a protective effect against the first occurrence of acute arterial events, but the impact of treatment with anti-TNF in patients with a previous history of acute arterial events remains unclear. We assessed the effect of anti-TNF and thiopurines on the risk of recurrent acute arterial events in patients with IBD in a nationwide cohort. METHODS Based on the French nationwide health insurance database, patients with IBD and a previous history of an acute arterial event were followed up from January 1, 2009, until December 31, 2018. The risk of acute arterial event recurrence associated with anti-TNF and thiopurine exposure was assessed using marginal structural Cox proportional hazard models adjusted for baseline and time-varying covariates. RESULTS A total of 27,185 patients were included. During 121,822 person-years (median follow-up period, 4.0 y), 6865 recurrent acute arterial events occurred (incidence rate per 1000 person-years, 56.4; 95% CI, 55.0-57.7). Exposure to both anti-TNF and thiopurines were associated with a decreased risk of recurrent acute arterial events compared with the absence of exposure to either treatment (hazard ratio, 0.75; 95% CI, 0.63-0.90 and hazard ratio, 0.76; 95% CI, 0.66-0.88, respectively). CONCLUSIONS In a nationwide cohort study of patients with IBD and a previous history of an acute arterial event, exposure to both anti-TNF and thiopurines were associated with a decreased risk of recurrent acute arterial events.

PERFUSE: a French non-interventional study of patients with inflammatory bowel disease receiving infliximab biosimilar SB2: a 12-month analysis. Therap Adv Gastroenterol 2023; 16:17562848221145654. [PMID: 36936799 PMCID: PMC10021102 DOI: 10.1177/17562848221145654] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Accepted: 11/28/2022] [Indexed: 03/21/2023] Open
Abstract
Background FlixabiTM (SB2) is a biosimilar of the reference infliximab (IFX), Remicade®. Published evidence on long-term, real-world use of SB2 in patients either IFX naive or transitioned from prior IFX is scarce. Objectives We evaluated persistence, effectiveness, and safety of SB2 over 12 months in adults with IBD [Crohn's disease (CD) and ulcerative colitis (UC)], participating in PERFUSE. Design PERFUSE is a long-term, non-interventional, multicenter study of patients receiving SB2 at specialist sites across France. Methods SB2 treatment was initiated in September 2017, either as first IFX treatment (IFX naive), after transition from treatment with reference IFX (IFX ref) or another IFX biosimilar (IFX bs), or both IFX ref and IFX bs (IFX multiswitch). Outcomes up to Month 12 (±2) include persistence on SB2 (primary outcome measure), SB2 dose, disease status, immunogenicity, and safety. Results This final 12-month analysis of patients with IBD includes 569 with CD and 168 with UC. Persistence [95% confidence interval (CI)] at Month 12 was CD: 89% (77.2; 94.9), UC: 78.5% (58.2; 89.8) for IFX naive; CD: 94% (91.0; 96.1), UC: 92.8% (84.8; 96.7) for IFX ref; CD: 91.6% (86.0; 95.0), UC: 94.2% (83.1; 98.1) for IFX bs; and CD 100% (100; 100), UC 100% (100; 100) for IFX multiswitch. In the CD and UC cohorts, disease activity among IFX naive patients declined from baseline to Month 12; with any prior IFX, the proportions of patients in remission at baseline, Month 6, and Month 12 remained unchanged in the UC cohort, and were comparable or higher in the CD cohort. No immunogenicity or safety signals were detected. Conclusions Patients with IBD can be initiated on SB2 or transitioned from IFX ref and/or IFX bs to SB2, with no loss of disease control or safety concerns, with >75% of naive and >90% of transitioned patients continuing on SB2 treatment at 12 months.

BACKGROUND Although primary tumor sidedness (PTS) has a known prognostic role in sporadic colorectal cancer (CRC), its role in Inflammatory Bowel Disease related CRC (IBD-CRC) is largely unknown. Thus, we aimed to evaluate the prognostic role of PTS in patients with IBD-CRC. METHODS All eligible patients with surgically treated, non-metastatic IBD-CRC were retrospectively identified from institutional databases at ten European and Asian academic centers. Long term endpoints included recurrence-free (RFS) and overall survival (OS). Multivariable Cox proportional hazard regression as well as propensity score analyses were performed to evaluate whether PTS was significantly associated with RFS and OS. RESULTS A total of 213 patients were included in the analysis, of which 32.4% had right-sided (RS) tumors and 67.6% had left-sided (LS) tumors. PTS was not associated with OS and RFS even on univariable analysis (5-year OS for RS vs LS tumors was 68.0% vs 77.3%, respectively, p = 0.31; 5-year RFS for RS vs LS tumors was 62.8% vs 65.4%, respectively, p = 0.51). Similarly, PTS was not associated with OS and RFS on propensity score matched analysis (5-year OS for RS vs LS tumors was 82.9% vs 91.3%, p = 0.79; 5-year RFS for RS vs LS tumors was 85.1% vs 81.5%, p = 0.69). These results were maintained when OS and RFS were calculated in patients with RS vs LS tumors after excluding patients with rectal tumors (5-year OS for RS vs LS tumors was 68.0% vs 77.2%, respectively, p = 0.38; 5-year RFS for RS vs LS tumors was 62.8% vs 59.2%, respectively, p = 0.98). CONCLUSIONS In contrast to sporadic CRC, PTS does not appear to have a prognostic role in IBD-CRC.

Comparative Risk of Incident Cancer in Patients with Inflammatory Bowel Disease with Prior Non-digestive Malignancy According to Immunomodulator: a Multicentre Cohort Study. J Crohns Colitis 2022; 16:1523-1530. [PMID: 35512337 DOI: 10.1093/ecco-jcc/jjac061] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Revised: 03/27/2022] [Accepted: 05/03/2022] [Indexed: 12/13/2022]
Abstract
INTRODUCTION Knowledge about the cancer risk when initiating a biologic in inflammatory bowel disease [IBD] patients with prior malignancy remains scarce, especially for vedolizumab. Our aim was to evaluate the rate of incident cancer in a cohort of IBD patients with prior non-digestive malignancy, according to the subsequent treatment given. METHODS A multicentre retrospective study included consecutive IBD patients with prior non-digestive malignancy. Inclusion date corresponded to the diagnosis of index malignancy. Patients were categorized into different cohorts according to the first treatment [none, conventional immunosuppressant, anti-TNF, or vedolizumab] to which they were exposed after inclusion and before incident cancer [recurrent or new cancer]. RESULTS Among the 538 patients {58% female; mean (standard deviation [SD]) age inclusion: 52 [15] years} analyzed, the most frequent malignancy was breast cancer [25%]. The first immunomodulator given after inclusion was a conventional immunosuppressant in 27% of patients, anti-TNF in 21%, or vedolizumab in 9%. With a median (interquartile range [IQR]) follow-up duration of 55 [23-100] months, 100 incident cancers were observed. Crude cancer incidence rates per 1000 person-years were 47.0 for patients receiving no immunomodulator, 36.6 in the anti-TNF cohort, and 33.6 in the vedolizumab cohort [p = 0.23]. Incident-cancer free survival rates were not different between patients receiving anti-TNF and those receiving vedolizumab [p = 0.56]. After adjustment, incidence rates were not different between patients receiving no immunomodulator, anti-TNF, or vedolizumab. CONCLUSIONS In this large multicentre cohort study, there was no difference of cancer incidence in those IBD patients with prior non-digestive malignancy, treated with vedolizumab or anti-TNF.

Rewiring the altered tryptophan metabolism as a novel therapeutic strategy in inflammatory bowel diseases. Gut 2022:gutjnl-2022-327337. [PMID: 36270778 DOI: 10.1136/gutjnl-2022-327337] [Citation(s) in RCA: 31] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Accepted: 10/06/2022] [Indexed: 11/04/2022]
Abstract
OBJECTIVE The extent to which tryptophan (Trp) metabolism alterations explain or influence the outcome of inflammatory bowel diseases (IBDs) is still unclear. However, several Trp metabolism end-products are essential to intestinal homeostasis. Here, we investigated the role of metabolites from the kynurenine pathway. DESIGN Targeted quantitative metabolomics was performed in two large human IBD cohorts (1069 patients with IBD). Dextran sodium sulphate-induced colitis experiments in mice were used to evaluate effects of identified metabolites. In vitro, ex vivo and in vivo experiments were used to decipher mechanisms involved. Effects on energy metabolism were evaluated by different methods including Single Cell mEtabolism by profiling Translation inHibition. RESULTS In mice and humans, intestinal inflammation severity negatively correlates with the amount of xanthurenic (XANA) and kynurenic (KYNA) acids. Supplementation with XANA or KYNA decreases colitis severity through effects on intestinal epithelial cells and T cells, involving Aryl hydrocarbon Receptor (AhR) activation and the rewiring of cellular energy metabolism. Furthermore, direct modulation of the endogenous tryptophan metabolism, using the recombinant enzyme aminoadipate aminotransferase (AADAT), responsible for the generation of XANA and KYNA, was protective in rodent colitis models. CONCLUSION Our study identified a new mechanism linking Trp metabolism to intestinal inflammation and IBD. Bringing back XANA and KYNA has protective effects involving AhR and the rewiring of the energy metabolism in intestinal epithelial cells and CD4+ T cells. This study paves the way for new therapeutic strategies aiming at pharmacologically correcting its alterations in IBD by manipulating the endogenous metabolic pathway with AADAT.

Decreased risk of treatment failure with vedolizumab and thiopurines combined compared with vedolizumab monotherapy in Crohn's disease. Gut 2022; 71:1781-1789. [PMID: 35387877 DOI: 10.1136/gutjnl-2022-327002] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Accepted: 03/27/2022] [Indexed: 12/08/2022]
Abstract
OBJECTIVE While infliximab combined to thiopurines is more effective than infliximab monotherapy in patients with Crohn's disease (CD) and UC, the impact of adding thiopurines to vedolizumab remains controversial. We emulated two target trials comparing the effectiveness of combination therapy versus vedolizumab monotherapy in CD and UC. DESIGN Based on two US and the French nationwide healthcare databases, patients with CD and UC who initiated vedolizumab were identified. The study methodology, including confounding adjustment and outcome definitions, were previously validated in successful emulations of the SONIC and SUCCESS trials. Risk ratios for treatment failure based on hospitalisation or surgery related to disease activity, treatment switch, or prolonged corticosteroids use, were estimated after 1:1 propensity score (PS) matching. RESULTS Among a total of 10 299 vedolizumab users, 804 CD and 1088 UC pairs of combination therapy versus vedolizumab monotherapy users were PS matched. Treatment failure occurred at week 26 in 236 (29.3%) and 376 (34.3%) patients with CD and at week 16 in 236 (21.7%) and 263 (24.2%) patients with UC initiating combination therapy and vedolizumab monotherapy, respectively. The risk of treatment failure was decreased with combination therapy compared with vedolizumab monotherapy in CD (RR 0.85, 95% CI: 0.74 to 0.98) and to a lesser extent in UC (RR 0.90, 95% CI: 0.77 to 1.05). Findings were consistent across databases. CONCLUSION Using validated methodologies, combination therapy with vedolizumab and thiopurines was associated with lower treatment failure compared with vedolizumab monotherapy in CD but not UC across the USA and France.

Abstract
BACKGROUND Patients with primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD) are at risk of biliary tract cancer and liver damage (possibly leading to liver transplantation), and are often treated for IBD with thiopurines and/or tumour necrosis factor antagonists (anti-TNF) on a long-term basis. AIMS To assess the risk of biliary tract cancer and liver transplantation in patients exposed to thiopurines and/or anti TNF agents in a French nationwide cohort. METHODS We performed a population-based study of patients aged 18 years or older with PSC and IBD in the French national health insurance database. Patients were followed from 1 January 2009 to 31 December 2018. The risks of biliary tract cancer and liver transplantation associated with thiopurines and anti-TNF exposure were assessed with marginal structural Cox proportional hazard models, adjusting for baseline demographics and comorbidities, and time-varying medications and PSC activity. RESULTS Among the 1929 patients with PSC and IBD included, 37 biliary tract cancers and 83 liver transplantations occurred. Compared with patients not exposed to thiopurines or anti-TNF agents, patients exposed to thiopurines (hazard ratio [HR], 1.05; 95% confidence interval [CI], 0.39-2.82) or anti-TNF agents (HR, 0.59; 95% CI, 0.13-2.80) had no excess risk of biliary tract cancer. Similarly, patients exposed to thiopurines (HR, 0.67; 95% CI, 0.30-1.48) or anti-TNF agents (HR, 0.68; CI, 0.22-2.09) had no excess risk of liver transplantation. CONCLUSIONS Patients with PSC and IBD who are exposed to thiopurines or anti-TNF agents are not at excess risk of biliary tract cancer or liver transplantation.

Abstract
Genome-wide association studies (GWASs) have identified hundreds of loci associated with Crohn's disease (CD). However, as with all complex diseases, robust identification of the genes dysregulated by noncoding variants typically driving GWAS discoveries has been challenging. Here, to complement GWASs and better define actionable biological targets, we analyzed sequence data from more than 30,000 patients with CD and 80,000 population controls. We directly implicate ten genes in general onset CD for the first time to our knowledge via association to coding variation, four of which lie within established CD GWAS loci. In nine instances, a single coding variant is significantly associated, and in the tenth, ATG4C, we see additionally a significantly increased burden of very rare coding variants in CD cases. In addition to reiterating the central role of innate and adaptive immune cells as well as autophagy in CD pathogenesis, these newly associated genes highlight the emerging role of mesenchymal cells in the development and maintenance of intestinal inflammation.

Abstract
BACKGROUND AND AIMS Patients with ulcerative colitis [UC] are at increased risk of colorectal cancer. Anti-tumour necrosis factor agents [anti-TNF] aim to reduce chronic colonic inflammation and may lower the risk of colorectal cancer [CRC], but the impact of anti-TNF exposure has not yet been assessed in population-based cohort studies. The aim of this nationwide study was to assess the risk of CRC in patients with UC exposed to anti-TNF. METHODS Based on the French health insurance database, patients aged 18 years or older with a diagnosis of UC, previously exposed to or initiating immunosuppressive treatment, were followed from January 1, 2009, until December 31, 2018. The risk of CRC associated with anti-TNF exposure was assessed using marginal structural Cox proportional hazard models adjusting for baseline and time-varying comorbidities including primary sclerosing cholangitis, UC disease activity, colonoscopic surveillance, and other medications. RESULTS Among 32 403 patients with UC, 15 542 [48.0%] were exposed to anti-TNF. During a median follow-up of 6.1 years [198 249 person-years], 246 incident CRC occurred (incidence rate per 1000 person-years, 1.24; 95% confidence intrval [CI], 1.10-1.41). Whereas the risk of CRC associated with anti-TNF exposure was not decreased in the overall group of patients with UC (hazard ratio [HR], 0.85; 95% CI, 0.58-1.26), anti-TNF exposure was associated with a decreased risk of CRC in patients with long-standing colitis [disease duration ≥10 years] [HR, 0.41; 95% CI, 0.20-0.86]. CONCLUSIONS In a nationwide cohort of patients with UC, anti-TNF exposure was associated with a decreased risk of CRC in patients with long-standing colitis.

Abstract
Due to the potential role of the gut microbiota and bile acids in the pathogenesis of both inflammatory bowel disease (IBD) and sporadic colorectal cancer, we aimed to determine whether these factors were associated with colorectal cancer in IBD patients. 215 IBD patients and 51 non-IBD control subjects were enrolled from 10 French IBD centers between September 2011 and July 2018. Fecal samples were processed for bacterial 16S rRNA gene sequencing and bile acid profiling. Demographic, clinical, endoscopic, and histological outcomes were recorded. Characteristics of IBD patients included: median age: 41.6 (IQR 22); disease duration 13.2 (13.1); 47% female; 21.9% primary sclerosing cholangitis; 109 patients with Crohn's disease (CD); 106 patients with ulcerative colitis (UC). The prevalence of cancer was 2.8% (6/215: 1 CD; 5 UC), high-grade dysplasia 3.7% (8/215) and low-grade dysplasia 7.9% (17/215). Lachnospira was decreased in IBD patients with cancer, while Agathobacter was decreased and Escherichia-Shigella increased in UC patients with any neoplasia. Bile acids were not associated with cancer or neoplasia. Unsupervised clustering identified three gut microbiota clusters in IBD patients associated with bile acid composition and clinical features, including a higher risk of neoplasia in UC in two clusters when compared to the third (relative risk (RR) 4.07 (95% CI 1.6-10.3, P < .01) and 3.56 (95% CI 1.4-9.2, P < .01)). In this multicentre observational study, a limited number of taxa were associated with neoplasia and exploratory microbiota clusters co-associated with clinical features, including neoplasia risk in UC. Given the very small number of cancers, the robustness of these findings will require assessment and validation in future studies.

Abstract
BACKGROUND AND AIMS Inflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), and human immunodeficiency virus (HIV) both impact innate and adaptive immunity in the intestinal mucosa. As it is a rare situation, the intersection between HIV and IBD remains unclear, especially the impact of HIV infection on the course of IBD, and the drug safety profile is unknown. METHODS We conducted a multicenter retrospective cohort study between January 2019 and August 2020. All adult patients with IBD and concomitant HIV infection were included. Each IBD patient with HIV was matched to two HIV-uninfected IBD patients. RESULTS Overall, 195 patients with IBD were included, including 65 HIV-infected patients and 130 without HIV infection. Of the 65 infected patients, 22 (33.8%) required immunosuppressants and 31 (47.7%) biologics. In the HIV-infected group, the need for immunosuppressants (p = 0.034 for CD and p = 0.012 for UC) and biologics (p = 0.004 for CD and p = 0.008 for UC) was significantly lower. The disease course, using a severity composite criterion, was not significantly different between the two groups for CD (hazard ration (HR) = 1.3 [0.7; 2.4], p = 0.45) and UC (HR, 1.1 [0.5; 2.7], p = 0.767). The overall drug safety profile was statistically similar between the two groups. CONCLUSION Although HIV-infected patients receive less treatments, the course of their IBD did not differ than uninfected, suggesting that HIV infection might attenuate IBD. The drug safety profile is reassuring, allowing physician to treat these patients according to current recommendations.

Abstract
BACKGROUND & AIMS The risk of serious infections associated with vedolizumab in patients with inflammatory bowel disease (IBD) is uncertain. We assessed the risk of serious infections associated with use of vedolizumab versus anti-TNF in patients with IBD, according to IBD subtype and previous exposure to anti-TNF. METHODS Based on two U.S. nationwide commercial insurance databases and the French nationwide health insurance database, anti-TNF naïve and experienced patients diagnosed with Crohn's disease (CD) and ulcerative colitis (UC) aged 18 years or older who initiated vedolizumab or an anti-TNF agent after 2010 were identified. Hazard ratios for serious infections comparing vedolizumab and anti-TNF were estimated in propensity score matched cohorts. RESULTS Among 8768 vedolizumab and 26,656 anti-TNF initiators included after 1:4 variable ratio propensity score matching, 893 serious infections occurred during 37,725 person-years of follow-up. The risk of serious infections was not different between vedolizumab and anti-TNF in the overall IBD cohort (HR, 0.95; 95% CI, 0·79-1.13), while the risk was decreased for vedolizumab users in patients with UC (HR, 0.68; 95% CI, 0.50-0.93), but not CD (HR, 1.10; 95% CI, 0.87-1.38). In patients with UC, vedolizumab was consistently associated with lower risk of serious infections after exclusion of gastrointestinal infections (HR, 0.59; 95% CI, 0.39-0.90). CONCLUSIONS While the risk of serious infections associated with vedolizumab was not different compared to anti-TNF in the overall group of patients with IBD, the risk varied according to IBD subtype, by decreasing in patients with UC, but not CD. These findings may help to clarify the optimal position of vedolizumab in the therapeutic management of IBD.

Abstract
INTRODUCTION Vedolizumab clinical decision support tool (VDZ-CDST) predicts response to vedolizumab, but whether this tool also predicts efficacy of other drugs in Crohn's disease (CD) is unknown. This study aimed to assess the value of VDZ-CDST to predict vedolizumab and ustekinumab efficacy in patients with CD. PATIENTS AND METHODS We included consecutive CD patients refractory or intolerant to anti-TNF who started either vedolizumab or ustekinumab in 5 university hospitals between May 2014 and August 2018. The main end points were the rates of clinical remission and steroid-free clinical remission (SFCR) in each group of VDZ-CDST at week 48. RESULTS One hundred eighty patients were included; 94 received vedolizumab (VDZ-CDST ≤13: 32; VDZ-CDST >13 and ≤19: 52; VDZ-CDST >19: 10), and 86 received ustekinumab (VDZ-CDST ≤13: 16; VDZ-CDST >13 and ≤19: 60; VDZ-CDST >19: 10). At week 48 in the vedolizumab group, clinical remission and SFCR were reached in 9.4% with a VDZ-CDST ≤13, in 38.5% and 28.8% with a VDZ-CDST >13 and ≤19, respectively, and in 80.0% with a VDZ-CDST >19 (P < 0.0001 and P < 0.0001, respectively). In the ustekinumab cohort, clinical remission and SFCR were reached in 43.8% and 37.5% with a VDZ-CDST ≤13, in 55.0% and 50.0% with a VDZ-CDST >13 and ≤19, and 50.0% with a VDZ-CDST >19, respectively (P = 0.65 and P = 0.46, respectively). VDZ-CDST identified SFCR with an area under the curve of 0.69 (95% CI, 0.57-0.82) for vedolizumab and 0.52 (95% CI, 0.40-0.65) for ustekinumab. CONCLUSION The VDZ-CDST predicts clinical remission and SFCR at week 48 for vedolizumab but not for ustekinumab in CD patients refractory or intolerant to anti-TNF.

Abstract
PURPOSE To understand the validity of real-world evidence (RWE) studies in ulcerative colitis (UC), we emulated the SUCCESS randomized controlled trial (RCT) on the effectiveness of infliximab plus thiopurines, using US and French healthcare insurance claims data. METHODS The SUCCESS trial showed improved remission with infliximab plus thiopurines combined compared to infliximab monotherapy in patients with UC. Based on two US commercial claims databases (IBM MarketScan and Optum) and the French nationwide health insurance database (SNDS) from 2004 through 2019, all patients with UC who initiated combination therapy or infliximab alone were identified. The primary outcome of treatment failure was emulated by: Hospitalization related to UC or colectomy, treatment switch to another biologic or immunosuppressant, or use of corticosteroids 16 weeks after infliximab initiation. We estimated risk ratios with 95% confidence intervals after 1:1 propensity score (PS) matching. RESULTS Among 620 PS-matched pairs of combination therapy and infliximab monotherapy users, treatment failure occurred in 124 (20%) of patients initiating combination therapy and 170 (27%) during monotherapy. Like in SUCCESS, the risk of treatment failure was decreased with combination therapy in the overall cohort (RR = 0.73; 95% CI: 0.60-0.90). Findings were consistent across MarketScan, Optum, and SNDS: RR = 0.76 (0.57-1.02), 0.82 (0.54-1.24), and 0.61 (0.41-0.90). Similar results were observed for each component endpoint. CONCLUSIONS RWE results across three large claims databases were consistent with RCT findings. These findings provide support for the use of RWE to assess treatment effectiveness in UC.

Abstract
BACKGROUND Restorative proctocolectomy with ileal-pouch anal-anastomosis (IPAA) is the operation of choice for patients with ulcerative colitis (UC) or with inflammatory bowel diseases unclassified (IBDU). AIMS to assess the incidence and risk factors of chronic pouchitis (CP) and Crohn's disease of the pouch (CDP) in patients with UC or IBDU. METHODS We conducted a retrospective study. We included consecutive patients who underwent IPAA between 2011 and 2019. The main outcome was the occurrence of CP or CDP. We looked for risk factors with multivariable and a least absolute shrinkage and selection operator (LASSO) Cox models. RESULTS 247 patients were included. The 5-year cumulative incidence of CP or CDP was 35.3% (95%CI: 26.2-43.2). In multivariable analysis, diagnosis of IBDU, age less than 35 years at surgery and extra-intestinal manifestations other than articular and primary sclerosing cholangitis were associated with higher incidence. The LASSO analysis identified these three prognostic factors and articular manifestations. In patients with two or more prognostic factors, 5-year cumulative incidence, was 65.2% (95%CI: 41.8-79.2). CONCLUSIONS Five years after IPAA, approximately one-third of patients had either CP or CDP. Risk factors were IBDU, an age less than 35 years at surgery, articular manifestations and other extra-intestinal manifestations.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a chronic inflammatory disorder, primarily of, but not restricted to, the gut. Association between IBD and cancer has been clearly established and is uniformly accepted. SUMMARY IBD patients are at particular risk for intestinal and extraintestinal cancers. There are 2 underlying mechanisms: (1) IBD-related inflammation triggers initiation and progression of tumor formation. This particularly results in the development of colorectal cancer, small bowel adenocarcinoma, intestinal lymphoma, anal cancer, and cholangiocarcinoma. (2) Immunosuppressive drugs exhibit carcinogenic properties such as shown for azathioprine and anti-TNF promoting lymphoproliferative malignancies and melanoma and nonmelanoma skin cancer. However, within the last years, IBD-related cancer incidence and prevalence have been decreasing, which might be attributed to better treatment options and surveillance strategies. Moreover, novel biological drugs have been introduced in clinical practice and have dramatically changed long-term IBD management. Therefore, we sought to summarize up-to-date knowledge about (1) overall cancer risk; (2) risk and protective factors for cancer development; and (3) inflammation- and immunosuppression-related malignancies in the current anti-TNF era of IBD. Key Messages: Recent studies and meta-analyses questioned the excess rates of cancer in IBD patients. However, IBD still is associated with cancer development due to ongoing intestinal inflammation and the use of potential carcinogenic drugs. Patients should be educated about the increased risk of cancer with IBD and IBD drugs. However, they should also be informed that most malignancy subtypes are possibly preventable by controlling intestinal inflammation and by using adequate screening strategies.

A Scoring System to Determine Patients' Risk of Colectomy Within 1 Year After Hospital Admission for Acute Severe Ulcerative Colitis. Clin Gastroenterol Hepatol 2021; 19:1602-1610.e1. [PMID: 31927106 DOI: 10.1016/j.cgh.2019.12.036] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2019] [Revised: 12/12/2019] [Accepted: 12/23/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS There is consensus on the criteria used to define acute severe ulcerative colitis (ASUC) and on patient management, but it has been a challenge to identify patients at risk for colectomy based on data collected at hospital admission. We aimed to develop a system to determine patients' risk of colectomy within 1 y of hospital admission for ASUC based on clinical, biomarker, and endoscopy data. METHODS We performed a retrospective analysis of consecutive patients with ASUC treated with corticosteroids, ciclosporin, or tumor necrosis factor (TNF) antagonists and admitted to 2 hospitals in France from 2002 through 2017. Patients were followed until colectomy or loss of follow up. A total of 270 patients with ASUC were included in the final analysis, with a median follow-up time of 30 months (derivation cohort). Independent risk factors identified by Cox multivariate analysis were used to develop a system to identify patients at risk for colectomy 1 y after ASUC. We developed a scoring system based on these 4 factors (1 point for each item) to identify high-risk (score 3 or 4) vs low-risk (score 0) patients. We validated this system using data from an independent cohort of 185 patients with ASUC treated from 2006 through 2017 at 2 centers in France. RESULTS In the derivation cohort, the cumulative risk of colectomy was 12.3% (95% CI, 8.6-16.8). Based on multivariate analysis, previous treatment with TNF antagonists or thiopurines (hazard ratio [HR], 3.86; 95% CI, 1.82-8.18), Clostridioides difficile infection (HR, 3.73; 95% CI, 1.11-12.55), serum level of C-reactive protein above 30 mg/L (HR, 3.06; 95% CI, 1.11-8.43), and serum level of albumin below 30 g/L (HR, 2.67; 95% CI, 1.20-5.92) were associated with increased risk of colectomy. In the derivation cohort, the cumulative risks of colectomy within 1 y in patients with scores of 0, 1, 2, 3, or 4 were 0.0%, 9.4% (95% CI, 4.3%-16.7%), 10.6% (95% CI, 5.6%-17.4%), 51.2% (95% CI, 26.6%-71.3%), and 100%. Negative predictive values ranged from 87% (95% CI, 82%-91%) to 92% (95% CI, 88%-95.0%). Findings from the validation cohort were consistent with findings from the derivation cohort. CONCLUSIONS We developed a scoring system to identify patients at low-risk vs high-risk for colectomy within 1 y of hospitalization for ASUC, based on previous treatment with TNF antagonists or thiopurines, C difficile infection, and serum levels of CRP and albumin. The system was validated in an external cohort.

Abstract
BACKGROUND/AIMS Few data on the evolution of endoscopic findings are available in patients with acute severe ulcerative colitis (ASUC). The aim of this study was to describe this evolution in a prospective cohort. METHODS Patients admitted for a steroid-refractory ASUC and included in a randomized trial comparing infliximab and cyclosporine were eligible if they achieved steroid-free clinical remission at day 98. Flexible sigmoidoscopies were performed at baseline, days 7, 42 and 98. Ulcerative colitis endoscopic index of severity (UCEIS) and its sub-scores - vascular pattern, bleeding and ulceration/erosion - were post-hoc calculated. Global endoscopic remission was defined by a UCEIS of 0, and partial endoscopic remission by any UCEIS sub-score of 0. RESULTS Among the 55 patients analyzed (29 infliximab and 26 cyclosporine), 49 (83%) had UCEIS ≥6 at baseline at baseline. Partial endoscopic remission rates were higher for bleeding than for vascular pattern and for ulcerations/erosions at day 7 (20% vs. 4% and 5% (n = 55); p = .004 and p=.04), for bleeding and ulceration/erosion than for vascular pattern at day 42 [63% and 65% vs. 33% (n=54); p<.001 for both] and at day 98 [78% and 92% vs. 56% (n = 50); p = .007 and p < .001]. Global endoscopic remission rates at day 98 were higher in patients treated with infliximab than with cyclosporine [73% vs. 25% (n = 26 and 24); p < .001]. CONCLUSION In steroid-refractory ASUC patients responding to a second-line medical therapy, endoscopic remission process started with bleeding remission and was not achieved in half the patients at day 98 for vascular pattern. Infliximab provided a higher endoscopic remission rate than cyclosporine at day 98.

Abstract
Real-world evidence (RWE) on the effectiveness of treatments in Crohn's disease (CD) derived from clinical practice data will help fill many evidence gaps left by randomized controlled trials (RCTs). Emulating RCTs with healthcare database studies may calibrate RWE studies in CD. We aimed to emulate the SONIC trial on the effectiveness of infliximab in patients with CD using US and French healthcare claims data. SONIC had shown improved remission with combination therapy (i.e., infliximab plus thiopurines) compared with infliximab monotherapy. Using claims data (2004-2019) from commercially insured patients in the United States (IBM MarketScan and Optum) and France (Système National des Données de Santé (National Healthcare Data System) (SNDS)), we conducted a cohort study of patients with CD who initiated combination therapy and compared them with patients who initiated infliximab alone. The primary outcome was a composite end point of treatment failure including hospitalization or surgery related to CD, treatment switch, or continuation of corticosteroids 26 weeks after infliximab initiation. Risk ratios (RRs) with 95% confidence intervals (CIs) were estimated in propensity score (PS)-matched cohorts. We identified 1,437 PS-matched pairs of combination therapy vs. infliximab monotherapy users. As in SONIC, the risk of treatment failure was decreased with combination therapy in the overall cohort (RR, 0.71; 95% CI, 0.62-0.82; RR, 0.78; 95% CI, 0.62-0.97 in SONIC). Findings were consistent across MarketScan, Optum, and SNDS databases: RR (95% CI), 0.83 (0.63-1.10), 0.66 (0.46-0.93), and 0.68 (0.57-0.82), as well as component end points. These robust findings highlight opportunities in RWE analysis for studying treatment effectiveness in patients with CD in clinical practice.

Abstract
BACKGROUND Lymphoma is a dreaded complication of inflammatory bowel diseases [IBD]. Knowledge about lymphoma in patients with IBD is limited to epidemiological data and the description of risk factors. We performed a systematic review to describe the clinical characteristics and prognosis of lymphoma in patients with IBD. METHODS Electronic databases were searched up to June 1, 2020. All published clinical characteristics of lymphoma occurring in patients with IBD were collected. RESULTS Eleven studies were included. A total of 589 lymphomas were described in patients with IBD. As seen in de novo lymphoma, non-Hodgkin's lymphoma [NHL] was the most common histological subtype [83.9%]. Diffuse large B-cell lymphoma [DLBCL] and follicular lymphoma were the most well-represented NHL in patients with IBD [30% and 13% respectively]. Two main differences were observed in comparison with de novo lymphoma: primary intestinal lymphoma [PIL] represented a large proportion of lymphoma in patients with IBD [22-75%] whereas mucosa-associated lymphoid tissue [MALT] lymphoma was under-represented. Epstein-Barr virus [EBV]-positive status was observed in a large proportion of tumours [44-75%]. Survival data of lymphoma in patients with IBD were similar to those of de novo lymphoma. DISCUSSION This systematic review first highlights that PIL [especially DLBCL subtype] is significantly more frequent in patients with IBD and represents the most common entity. Conversely, MALT lymphoma is extremely rare in the IBD population. However, the overall quality of the evidence is low. Further studies are required to better define lymphoma characteristics in patients with IBD.

Abstract
PURPOSE Subtotal colectomy (STC) is performed for severe acute and refractory colitis. The diagnosis can be difficult even after the surgery when colectomy specimen has overlapping features of ulcerative colitis (UC) and Crohn's disease (CD). The aim of this study was to evaluate the rate of postoperative diagnostic revision to CD after surgery and determine predictor factors. METHODS Retrospective study of 110 patients who underwent STC (2005-2018). RESULTS Preoperative diagnosis comprised UC = 80 (73%), CD = 11 (10%), and unclassified colitis (IBDU = 19, 17%). Initial diagnosis of IBDU and UC was modified to CD in 6 patients (6%) after STC. The final diagnosis after the follow-up of 10 ± 6 years switched from CD for 8 patients (9%). The multivariate analysis showed that patients with a colitis evolving for less than 10 years and initial diagnosis of IBDU were the two independent factors associated with an increased risk of diagnosis change to CD (p = 0.03; p = 0.016). At the end of the follow-up, 15 patients (14%) had a definitive stoma. CONCLUSIONS In patients with IBD, attention must be paid to determine the right restorative strategy to patients with an evolution of the disease less than 10 years or with IBDU who are more at risk to have a diagnosis change to CD after STC.

Abstract
In Crohn's disease, combination therapy with anti-tumor necrosis factor (anti-TNF) agents and azathioprine/mercaptopurine has been shown to be superior to monotherapy with one of these treatments alone.1 This combination has its best success rate when used early in the course of treatment.2 However, because of the significant cost of these drugs and concerns over long-term side effects,3,4 many patients and providers often ask about stopping one or both of these medications.

Linking Strain Engraftment in Fecal Microbiota Transplantation With Maintenance of Remission in Crohn's Disease. Gastroenterology 2020; 159:2193-2202.e5.

Abstract
BACKGROUND & AIMS Crohn's disease (CD) is a chronic gastrointestinal disease resulting from the dysfunctional interplay between genetic susceptibility, the immune system, and commensal intestinal microbiota. Emerging evidence suggests that treatment by suppression of the immune response and replacement of the microbiota through fecal microbiota transplantation (FMT) is a promising approach for the treatment of CD. METHODS We obtained stool metagenomes from CD patients in remission and assessed gut microbiome composition before and after FMT at the species and strain levels. Longitudinal follow-up evaluation allowed us to identify the gain, loss, and strain replacement of specific species and link these events to the maintenance of remission in CD. RESULTS We found that FMT had a significant long-term effect on patient microbial compositions, although this was primarily driven by the engraftment of donor species, which remained at low abundance. Thirty-eight percent of FMT-driven changes were strain replacements, emphasizing the importance of detailed profiling methods, such as metagenomics. Several instances of long-term coexistence between donor and patient strains were also observed. Engraftment of some Actinobacteria, and engraftment or loss of Proteobacteria, were related to better disease outcomes in CD patients who received FMT, and transmission of Bacteroidetes was deleterious. CONCLUSIONS Our results suggest clades that may be beneficial to transmit/eliminate through FMT, and provide criteria that may help identify personalized FMT donors to more effectively maintain remission in CD patients. The framework established here creates a foundation for future studies centered around the application of FMT and defined microbial communities as a therapeutic approach for treating CD.

Abstract
AIMS The aims of this study were to describe outcomes in patients with Crohn's disease who fail anti-tumor necrosis factor (TNF) and either vedolizumab or ustekinumab. METHODS Multicenter, retrospective study of 100 patients with Crohn's disease who failed anti-TNF and either vedolizumab or ustekinumab from 2015 to 2019. Using multivariable Cox regression, we sought to identify factors associated with need for surgery. RESULTS 75 patients received a third line treatment, resulting in 23 (30.7%) clinical remission at week 48. Among the 71 patients included after vedolizumab failure, 46 received ustekinumab, resulting in 46 (28.3%) clinical remission; 13 patients were retreated with an anti-TNF, resulting in 13 (46.2%) clinical remission. Among the 29 patients included after ustekinumab failure, 12 were retreated with an anti-TNF, resulting in 2 (16.7%) clinical remission. The rate of surgery-free survival at 48 weeks was 76.5% (95% confidence interval 68.4% - 85.4%). In multivariable analysis, ileal disease localization (hazard ratio 9.0, 95% confidence interval 1.0-81.9) was associated with a higher risk of surgery. CONCLUSION In patients with Crohn's disease who have failed anti-TNF and either vedolizumab or ustekinumab, at week 48, the surgery rate is 23.5% and the remission rate after a third line biologic therapy is 30.7%.

Abstract
BACKGROUND AND AIMS The prognosis of lymphoma that occurs in patients with inflammatory bowel disease [IBD] is poorly known. METHODS A multicentre retrospective cohort analysis was done in seven French tertiary centres from 1999 to 2019. Only lymphoma occurring in patients with previous established diagnosis of IBD were analysed. The primary outcome was progression-free survival at 3 years. RESULTS A total of 52 patients [male 65%, Crohn's disease 79%, median age 48.3 years, median duration of IBD 10.1 years] were included, of whom 37 had been previously exposed to immunosuppressants and/or biologics for at least 3 months and 20 had primary intestinal lymphomas. The lymphoma histological types were: diffuse large B cell lymphomas [N = 17], Hodgkin lymphomas [N = 17], indolent B cell lymphomas [N = 12], and others including T cell lymphomas, mantle cell lymphomas, and unclassifiable B cell lymphoma [N = 6]. The median follow-up after lymphoma was 5.1 years (interquartile range [IQR] 4-7.8). Progression-free survival at 3 years was 85% in the overall population (95% confidence interval [CI] 75%-96%) with no significant difference between the exposed and unexposed group, 79% for patients exposed to immunosuppressants and/or biologics [95% CI 67%-94%], and 83% for patients diagnosed with primary intestinal lymphoma [95% CI 67%-100%]. No relapse of IBD has been observed during chemotherapy. The IBD relapse rate at the end of the last chemotherapy cycle was 23% at 3 years [95% CI 11%-39%] in the overall population. CONCLUSIONS In this large cohort, the prognosis for lymphomas occurring in IBD appears to be good and similar to what is expected, irrespective of the exposure to biologics and/or immunosuppressants.

Abstract
BACKGROUND Whether therapeutic drug monitoring (TDM) of infliximab should be implemented in daily practice is an ongoing controversy. AIMS To assess the real-world use of TDM in an observational multicentre cohort study with consecutive patients with inflammatory bowel disease (IBD) treated with CT-P13. METHODS Between September 2015 and December 2016, 364 patients with IBD were treated with CT-P13 in 13 gastroenterology departments and were followed up for 54 weeks. Disease activity, CT-P13 trough concentration and anti-CT-P13 antibody (ACA) were recorded. RESULTS Steroid-free clinical remission rates at week 54 were 67.0% and 56.4% in patients with CD and UC, respectively. CT-P13 trough concentrations were measured in 70.7% of the patients. The mean CT-P13 trough concentration was 4.2±4.3μg/mL. The presence of ACA was observed in 53 (15.9%) patients. CT-P13 trough concentration was collected in a proactive approach in 62.8% of cases and in a reactive approach in 37.2%. Among patients who submitted to TDM, CT-P13 therapy was optimized in 88.7% of the reactive group and in 22.5% of the proactive group (P<0.001). CONCLUSION In a real-world cohort of patients with IBD treated with CT-P13, more than two-thirds of the patients underwent TDM. CT-P13 optimization was much less common in the proactive approach than in the reactive approach.

Abstract
BACKGROUND AND AIM It is unclear whether vedolizumab therapy can be discontinued in patients with inflammatory bowel disease [IBD] after achieving steroid-free clinical remission. The aim was to assess the risk of relapse after vedolizumab therapy was discontinued. METHODS This was a retrospective observational study, collecting data from 21 tertiary centres affiliated with the GETAID from January 2017 to April 2019. Consecutive patients with IBD, who were in steroid-free clinical remission for at least 3 months and were treated with vedolizumab for at least 6 months, were included at the time of vedolizumab discontinuation. RESULTS A total of 95 patients [58 with Crohn's disease] discontinued vedolizumab after a median duration of therapy of 17.5 [10.6-25.4] months. After a median follow-up period of 11.2 [5.8-17.7] months, 61 [64%] patients experienced disease relapse. The probabilities of relapse-free survival were 83%, 59%, and 36% at 6, 12, and 18 months, respectively. According to the multivariate analysis, a C-reactive protein level less than 5 mg/L at vedolizumab discontinuation (hazard ratio [HR] = 0.56, 95% confidence interval [CI] [0.33-0.95], p = 0.03) and discontinuation due to patients' elective choice (HR = 0.41, 95% CI [0.21-0.80], p = 0.009) were significantly associated with a lower risk of relapse. Re-treatment with vedolizumab was noted in 24 patients and provided steroid-free clinical remission in 71% and 62.5% at Week 14 and after a median follow-up of 11.0 [5.4-13.3] months, respectively, without any infusion reactions. CONCLUSIONS In this retrospective study, two-thirds of patients with IBD treated with vedolizumab experienced relapse within the first year after vedolizumab discontinuation. Re-treatment with vedolizumab was effective in two-thirds of patients.

Abstract
BACKGROUND Crohn's disease (CD) and hidradenitis suppurativa (HS), a chronic inflammatory skin disease, induce similar inflammatory lesions of the groin and gluteal area. Both diseases are characterised by an inadequate immune response to commensal bacteria in genetically predisposed subjects and can be associated. AIM To assess whether HS was associated with clinical and prognostic factors in CD. METHODS A retrospective case-control study included 4645 patients with CD referred to Saint-Antoine Hospital gastroenterology tertiary care centre between 2003 and 2016. Matching variables were sex, age, age and the presence of perianal lesions at CD diagnosis, follow-up quality. HS was confirmed by dermatological examination; location, phenotype and severity (Hurley staging) were recorded. RESULTS Hidradenitis suppurativa prevalence was 0.95% (44 cases); 80% of patients displayed Hurley stage II or III disease. CD preceded HS in 70% of cases with a median interval of 9 years (IQR 5.25-12.75). CD with HS was more active (56% vs 40% years with active disease, P < 0.001) and required more anti-TNF agents (39% vs 23% years spent with anti-TNF treatment, P < 0.001) than CD without HS. HS was associated with a higher risk of permanent stoma, 16.8% (IQR 7.5-33.3) vs 2.5% (IQR 0.8-7.4) in the control group (P = 0.002). Multivariate analysis confirmed HS as independent risk factor for permanent stoma (odds ratio 6.19; 95% CI, 2.30-38.33; P < 0.001). CONCLUSIONS Hidradenitis suppurativa is associated with worse CD prognosis, more active disease and increased risk of permanent stoma, despite a higher use of anti-TNF agents.

Long-term outcome of patients with acute severe ulcerative colitis responding to intravenous steroids. Aliment Pharmacol Ther 2020; 51:1096-1104. [PMID: 32342994 DOI: 10.1111/apt.15751] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2019] [Revised: 11/28/2019] [Accepted: 04/05/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND The long-term outcome of patients with acute severe ulcerative colitis (ASUC) responding to intravenous steroids (IVS) has been poorly reported. AIMS To assess relapse-free survival in patients with ASUC responding to IVS. METHODS Between January 2006 and December 2017, 142 consecutive patients with ASUC (according to modified Truelove-and-Witts criteria) responding to IVS were included in this multicentre retrospective study. Relapse was defined by a partial Mayo Clinic score >4 and/or the need for another maintenance therapy. RESULTS Among the 142 included patients (100 naïve of immunomodulator and/or biological agent) hospitalised for ASUC, 59 (41.5%) were treated at discharge with 5-aminosalicylic acid, 60 (42%) with immunomodulators, 18 (13%) with anti-tumour necrosis factor (TNF) agents and 5 (3.5%) with vedolizumab. After a median follow-up of 4.8 (2.6-7.3) years, 90 (63.4%) had relapsed and 12 (8.5%) had required colectomy. The probabilities of relapse-free survival were 58%, 48% and 40% at 1, 2 and 5 years respectively. The multivariate analysis demonstrated that patients with <6 liquid stools per day at day 3 (hazard ratio 0.56, 95%CI [0.34-0.91]), a partial Mayo Clinic score <2 at day 5 (0.41 [0.21-0.80]) and anti-TNF maintenance therapy (0.37 [0.16-0.87]) were less likely to relapse. The probabilities of colectomy-free survival were 96%, 95% and 91% at 1, 2 and 5 years respectively. CONCLUSION Despite a high relapse rate, patients with ASUC responding to IVS had a low rate of colectomy after 5 years of follow-up. Early response to IVS and maintenance therapy with biological agents were associated with a lower rate of relapse.

Abstract
Background:Regulatory T cells (Tregs) prevent autoimmunity and control inflammation. As low-dose interleukin-2 (ld-IL2) expands and activates Tregs, it has a broad therapeutic potential for any autoimmune or inflammatory disease (AIID). We performed a disease-finding “basket trial” (TRANSREGNCT01988506) in patients affected by one of 11 different AIID and reported the outcome of the first 46 patients (Rosenzwajg et al, ARD 2019).Objectives:Here we analyzed and discussed results from deep immunophenotyping, of 78 patients, to comprehensively study the effect of ld-IL2 on the immune system of patients affected by various AIIDMethods:We performed a prospective, open label, phase I-IIa study in 78 patients with a mild to moderate form of one of 13 selected AIID. All patients received ld-IL2 (1 million IU/day) for 5 days, followed by fortnightly injections for 6 months. Deep immunophenotyping was performed before and after 5 days of ld-IL2.Results:ld-IL2 significantly expands both memory Tregs as well as naïve Tregs, including recent thymic emigrant Tregs. It also activates Tregs as demonstrated by the significantly increased expression of HLA-DR, CD39, CD73, GITR, CTLA-4. Similar results were observed across the different AIID.Conclusion:ld-IL2 “universally” improves Treg fitness across 13 autoimmune and inflammatory disease.References:[1]Rosenzwajg M#, Lorenzon R#, Cacoub P, Pham HP, Pitoiset F, El Soufi K, RIbet C, Bernard C, Aractingi S, Banneville B, Beaugerie L, Berenbaum F, Champey J, Chazouilleres O, Corpechot C, Fautrel B, Mekinian A, Regnier E, Saadoun D, Salem JE, Sellam J, Seksik P, Daguenel-Nguyen A, Doppler V, Mariau J, Vicaut E, Klatzmann D.

Toward Further Understanding of Crohn's Disease-Related Fatigue: The Role of Depression and Emotional Processing. Front Psychol 2020; 11:703.

Abstract
Because the relationship between Crohn’s Disease (CD) activity and CD-related fatigue remains poorly understood, this study investigated the role of underlying psychological processes (depression, anxiety, and emotional processing). It was expected that the relationship between CD activity and CD-related fatigue would be mediated by depression and anxiety and also by a deficit in emotional processing. This prediction was tested in 110 CD patients who completed self-reported questionnaires assessing fatigue (FSS), clinical activity of Crohn’s Disease (HBAI), psychological suffering (HADS), and emotional processing (EPS-25). A path analysis showed both direct and indirect effects in the relationship between CD activity and CD-related fatigue, accounting for 33% of the variance. One indirect effect on the experience of fatigue was depression, but there was no effect of anxiety. These preliminary results confirmed that disease activity induces an increase in depressive symptoms, which in turn leads to an increase in the level of fatigue. The most novel result of the present study is that emotional processing had an indirect effect on the relationship between CD and CD-related fatigue: when the disease was more active, patients exhibited greater disruption of emotional processing, which in turn led to greater fatigue. These results did not reveal any association between depression and emotional processing. In conclusion, this work highlights the role of emotional processing in CD-related fatigue and the importance of taking this factor into account in order to manage this condition better.

The effectiveness of either ustekinumab or vedolizumab in 239 patients with Crohn's disease refractory to anti-tumour necrosis factor. Aliment Pharmacol Ther 2020; 51:948-957. [PMID: 32249966 DOI: 10.1111/apt.15706] [Citation(s) in RCA: 79] [Impact Index Per Article: 19.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Revised: 11/15/2019] [Accepted: 03/10/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND There is no head-to-head trial comparing ustekinumab and vedolizumab in patients with Crohn's disease (CD) refractory to anti-tumour necrosis factor (anti-TNF). AIM To compare the effectiveness and safety of ustekinumab and vedolizumab in patients with CD refractory to anti-TNF in a multicentre retrospective observational cohort. METHODS All consecutive patients with CD refractory or intolerant to anti-TNF who initiated either vedolizumab or ustekinumab were included between May 2014 and August 2018. Clinical remission, steroid-free clinical remission (SFCR) and treatment persistence were assessed at week 48 with intention-to-treat analysis and propensity scores weighted comparison. RESULTS A total of 239 patients were included, 107 received ustekinumab and 132 received vedolizumab. At week 48, ustekinumab was associated with a higher clinical remission rate (54.4% vs 38.3%; odds ratios, OR = 1.92, 95% CI [1.09-3.39]) and treatment persistence (71.5% vs 49.7%; OR = 2.54, 95% CI [1.40-4.62]) than vedolizumab. The rate of SFCR did not differ significantly between ustekinumab and vedolizumab (44.7% vs 34.0%; OR = 1.57, 95% CI [0.88-2.79]). Subgroup analyses showed that ustekinumab was associated with a higher clinical remission rates at week 48 in patients with ileal location (OR = 3.49, 95% CI [1.33-9.17) and penetrating behaviour (OR = 6.58, 95% CI [1.91-22.68]). Regardless of the treatment group, combination therapy at initiation was associated with a higher clinical remission rate at week 48 (OR = 1.93, 95% CI [1.09-3.43]). CONCLUSION This study suggests that ustekinumab is associated with a higher rate of clinical remission and treatment persistence than vedolizumab after 48 weeks of follow-up, in patients with CD refractory or intolerant to anti-TNF. The rate of SFCR was not significantly different.

Risk of acute arterial events associated with treatment of inflammatory bowel diseases: nationwide French cohort study. Gut 2020; 69:852-858. [PMID: 31446428 DOI: 10.1136/gutjnl-2019-318932] [Citation(s) in RCA: 41] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2019] [Revised: 07/22/2019] [Accepted: 08/17/2019] [Indexed: 02/07/2023]
Abstract
OBJECTIVE Patients with IBD are at increased risk of acute arterial events. Antitumour necrosis factor (TNF) agents and thiopurines may, via their anti-inflammatory properties, lower the risk of acute arterial events. The aim of this study was to assess the impact of thiopurines and anti-TNFs on the risk of acute arterial events in patients with IBD. DESIGN Patients aged 18 years or older and affiliated to the French national health insurance with a diagnosis of IBD were followed up from 1 April 2010 until 31 December 2014. The risks of acute arterial events (including ischaemic heart disease, cerebrovascular disease and peripheral artery disease) were compared between thiopurines and anti-TNFs exposed and unexposed patients with marginal structural Cox proportional hazard models adjusting for baseline and time-varying demographics, medications, traditional cardiovascular risk factors, comorbidities and IBD disease activity. RESULTS Among 177 827 patients with IBD (96 111 (54%) women, mean age at cohort entry 46.2 years (SD 16.3), 90 205 (50.7%) with Crohn's disease (CD)), 4145 incident acute arterial events occurred (incidence rates: 5.4 per 1000 person-years). Compared with unexposed patients, exposure to anti-TNFs (HR 0.79, 95% CI 0.66 to 0.95), but not to thiopurines (HR 0.93, 95% CI 0.82 to 1.05), was associated with a decreased risk of acute arterial events. The magnitude in risk reduction was highest in men with CD exposed to anti-TNFs (HR 0.54, 95% CI 0.40 to 0.72). CONCLUSION Exposure to anti-TNFs is associated with a decreased risk of acute arterial events in patients with IBD, particularly in men with CD.

Abstract
BACKGROUND The natural history of intestinal lesions in Crohn's disease [CD] is not fully understood. Although the extent of lesions at diagnosis usually defines the extent of the disease, some lesions seen at diagnosis, particularly aphthous ulcers [AUs], may resolve before follow-up. The aim of this study was to evaluate the outcomes of CD patients with colonic AUs seen at diagnosis. METHODS CD patients with aphthous colitis at diagnosis who had been followed since 2001 were included in a case control study matched with two groups of controls: one without colonic involvement at diagnosis and a second group with colonic lesions more severe than AUs at diagnosis. RESULTS Seventy-five patients were included, with a median follow-up of 7.3 years [interquartile range 2.7-9.8]. Seventy-one per cent of those having a second colonoscopy at least 6 months after diagnosis were stable or healed. Medical treatments were similar between the three groups. The AU group's rate of ileal surgery was similar to those without colitis. In multivariate analysis, the independent factors associated with ileal resection were ileal involvement (odds ratio [OR]: 8.8; 95% confidence interval [CI] [7.68-33.75]; p = 0.002) and the presence of severe colitis (OR = 0.5; 95% CI [0.32-0.79], p = 0.003). The risk of ileal surgery was not influenced by the presence of aphthous colitis (OR: 0.63; 95% CI [0.37-1.1]; p = 0.1). CONCLUSION Aphthous colitis at diagnosis seems to resolve in most patients. This suggests that these lesions are of little clinical significance and may not need to be considered prior to ileal resection in CD or when making other important therapeutic decisions.
