RESUMO
BACKGROUND & AIMS: Because transmural healing (TH) could be the best therapeutic target in Crohn's disease (CD), we aimed to build and validate a score to assess TH and transmural response (TR), and to confirm their association with favorable CD outcomes. METHODS: DEVISE-CD project encompassed 2 retrospective cohorts (274 and 224 patients with CD for development and validation phase, retrospectively) and 1 multicenter prospective validation cohort (N = 46 patients). A step-by-step process was used to build the modified Clermont score (C-score). The primary end points were time to bowel damage progression, and steroid-free clinical remission with fecal calprotectin <250 at 1 year for retrospective and prospective validation cohorts, respectively. RESULTS: Edema, ulcer, contrast enhancement, diffusion-weighted hyperintensity, fat wrapping, bowel thickening (>3 mm), and enlarged lymph nodes were associated to higher risk of bowel damage progression (P < .01). Edema, diffusion-weighted hyperintensity, post-gadolinium contrast enhancement, and bowel thickening were highly coexistent (>95%) and collinear (P < .0001). Bowel thickness had the highest sensitivity to change after treatment (standardized mean difference = 0.30 ± 1.0; P = .001). C-score was calculated as 0.2x(bowel thickness-3mm) + 1.5x enlarged lymph nodes + 2x ulcer. TH (C-score <0.5; hazard ratio [HR], 0.28 [0.13-0.63]; P = .002; adjusted HR [aHR], 0.15 [0.04-0.53]; P = .003), TR50 (50% decrease of C-score; HR, 0.30 [0.15-0.63]; P = .001; aHR, 0.36 [0.14-0.88]; P = .025), or TR25 (25% decrease of C-score; HR, 0.37 [0.19-0.71]; P = .003; aHR, 0.46 [0.23-0.94]; P = .034) prevented bowel damage progression in development and validation cohorts, respectively. In the prospective validation cohort, achieving TH (OR, 4.6 [1.3-15.6]; P = .016), TR50 (OR, 6.9 [1.8-26.0]; P = .008), or TR25 (OR, 6.0 [1.6-22.3]; P = .008) after 12 weeks of anti-tumor necrosis factor therapy led to higher rate of corticosteroid-free remission at 1 year. CONCLUSIONS: C-score is a validated, reliable, and easy-to-use tool to assess TH and TR in patients with CD.
RESUMO
BACKGROUND & AIMS: The aim of this study was to assess the long-term effectiveness and safety of risankizumab maintenance treatment in a large real-world cohort of patients with Crohn's Disease (CD). METHODS: From May 2021 to August 2023, all consecutive patients with CD treated with risankizumab in 25 GETAID centers have been retrospectively included. The primary endpoint was steroid-free clinical remission (Harvey Bradshaw Index [HBI] <5) at 52 weeks. RESULTS: Of the 174 patients included, 99%, 93%, and 96% had been previously exposed to anti-TNF, vedolizumab, and ustekinumab, respectively. All patients had received ≥3 biologics, and 108 (62%) had previous intestinal resection. Median follow-up was 13.7 months (interquartile range, 10.0-18.1 months). The rates of steroid-free clinical remission and clinical remission at week 26 were 47% (72/152) and 52% (79/152), and 46% (58/125), and 48% (60/125) at week 52, respectively. Risankizumab persistence rates were 94%, 89%, and 79% at weeks 12, 26, and 52, respectively. At the end of follow-up, 45 (45/174; 26%) patients had discontinued risankizumab (loss of response, 42%; primary failure, 37%; intolerance, 13%). Thirty-six patients (36/174; 20.9%) were hospitalized, and 22 (22/174; 12.6%) required intestinal resection. Fifty-one patients (29%) had an adverse event, including 26 (15%) serious adverse events (CD flare, n = 17). One death (myocardial infarction) and one cancer (papillary thyroid carcinoma) were observed. CONCLUSION: This is the first real-life study to report long-term outcomes in patients with refractory CD treated with risankizumab. One-half of the patients achieved steroid-free clinical remission after 1 year, and the safety profile was consistent with the literature.
RESUMO
INTRODUCTION: We assessed the impact of a nationwide screening programme to reduce the risk of anal cancer in a large cohort of high-risk patients with HIV. METHODS: From a large database from one referral centre, all high-risk patients with HIV (men who have sex with men, history of anal or genital warts, or previous cervix human papillomavirus-related lesions) who were eligible to enter the French anal cancer screening programme (2011-2020) were retrospectively included. Adherence to the screening programme was defined as no interval >18 months between two visits. Standardized management included perianal visualization and standard anoscopy with biopsies of macroscopic abnormalities. RESULTS: Overall, 700 patients with HIV were included (median follow-up 8.4 years [interquartile range 4.3-9.2] and 1491.6 patient-years), and 336 had one or more proctology visit. A total of 13 patients were diagnosed with anal squamous cell carcinomas. The risk of anal cancer was higher with anal intra-epithelial neoplasia grade 3 (AIN3; hazard ratio [HR] 44.5 [95% confidence interval {CI} 11.2-176.6], p < 0.001), AIN2 (HR 11.9 [95% CI 2.1-66.9], p = 0.005), or high-grade dysplasia (HR 23.4 [95% CI 7.9-69.1], p < 0.001) than with low-grade dysplasia or no lesion. Among the patients who were strictly adherent to the screening programme (4.6% [32/700]), we did not report any AIN or anal cancer, but we also did not observe any significant reduction in the risk of anal cancer (p = 0.51), AIN3 (p = 0.28), high-grade dysplasia (p = 0.19), or any AIN lesions (p = 0.10) compared with non-adherent patients. In contrast, screened patients were more likely to be diagnosed with anal warts (HR 3.71 [95% CI 2.14-6.42], p < 0.001). CONCLUSION: Macroscopic high-grade dysplasia lesions are associated with a higher risk of developing anal cancer. Despite finding no cases of cancer during the screening programme, we also did not demonstrate a clear benefit from our screening programme for the prevention of anal cancer in high-risk patients with HIV.

BACKGROUND: While fecal calprotectin (Fcal) is now recommended, the positioning of intestinal ultrasonography (IUS) is still unknown to monitor patients with CD. AIMS: To assess the agreement between IUS performed by a novice sonographer and Fcal to detect active CD and to compare these two monitoring tools to determine the need for therapeutic escalation. METHODS: In this cross-sectional prospective study, we consecutively included CD patients ≥ 18 years-old with concomitant IUS and Fcal testing within 7 days. IUS was performed by a novice sonographer. The endpoints were the agreement between IUS and Fcal (> 150 µg/g) to detect active CD and the need for therapeutic escalation. RESULTS: Among 66 patients undergoing IUS, 56 patients had also Fcal testing. The agreement between IUS and Fcal to detect an active CD was 80.4% (κ-coefficient = 0.536 ± 0.127). Fcal, IUS or both had respectively the following positive (76.9%[54.0-99.8], 70.0%[49.9-90.1], and 81.8%[59.0-100.0]) and negative (81.4%[69.8-93.0], 88.9%[78.6-99.2], and 80.0%[68.3-91.7]) predictive values to detect active CD requiring therapeutic escalation. Using a 10 points-acceptability numerical scale, IUS presented with a better acceptability than Fcal (9.5 ± 1.2 vs 8.0 ± 2.3, p < 0.0001). Contrary to the agreement with Fcal and the performances of IUS to identify the need for therapeutic escalation, the duration of IUS procedure decreased over time (correlation coefficient = - 0.54, p = 0.001) and plateaued between 15 and 20 min-long from the 24th procedure. CONCLUSION: IUS and fecal calprotectin do not give the same information and could be complementary to monitor patients with CD.
RESUMO
OBJECTIVE: We used the postoperative recurrence model to better understand the role of adherent and invasive Escherichia coli (AIEC) bacteria in Crohn's disease (CD), taking advantage of a well-characterised postoperative cohort. DESIGN: From a prospective, multicentre cohort of operated patients with CD, AIEC identification was performed within the surgical specimen (M0) (N=181 patients) and the neoterminal ileum (n=119 patients/181) during colonoscopy performed 6 months after surgery (M6). Endoscopic postoperative recurrence was graded using Rutgeerts' index. The mucosa-associated microbiota was analysed by 16S sequencing at M0 and M6. Relative risks or ORs were adjusted on potential confounders. RESULTS: AIEC prevalence was twofold higher within the neoterminal ileum at M6 (30.3%) than within the surgical specimen (14.9%) (p<0.001). AIEC within the neoterminal ileum at M6 was associated with higher rate of early ileal lesions (i1) (41.6% vs 17.1%; aRR 3.49 (95% CI 1.01 to 12.04), p=0.048) or ileal lesions (i2b+i3) (38.2% vs 17.1%; aRR 3.45 (95% CI 1.06 to 11.30), p=0.040) compared with no lesion (i0). AIEC within the surgical specimen was predictive of higher risk of i2b-endoscopic postoperative recurrence (POR) (aOR 2.54 (95% CI 1.01 to 6.44), p=0.049) and severe endoscopic POR (aOR 3.36 (95% CI 1.25 to 9.06), p=0.017). While only 5.0% (6/119) of the patients were AIEC-positive at both M0 and M6, 43.7% (52/119), patients with history of positive test for AIEC (M0 or M6) had higher risk of ileal endoscopic POR (aOR 2.32 (95% CI 1.01 to 5.39), p=0.048)), i2b-endoscopic postoperative recurrence (aOR 2.41 (95% CI 1.01 to 5.74); p=0.048) and severe endoscopic postoperative (aOR=3.84 (95% CI 1.32 to 11.18), p=0.013). AIEC colonisation was associated with a specific microbiota signature including increased abundance of Ruminococcus gnavus. CONCLUSION: Based on the postoperative recurrence model, our data support the idea that AIEC are involved in the early steps of ileal CD. TRIAL REGISTRATION NUMBER: NCT03458195.

The REMSWITCH study recently demonstrated that switching from intravenous (IV) to subcutaneous (SC) infliximab (IFX) is feasible and well-accepted leading to a low risk of relapse in patients with inflammatory bowel disease (IBD).1 Because the doses of IV IFX depend on patients' weight contrary to SC IFX, whether the switch is also feasible in patients with IBD suffering from obesity remains questionable.
RESUMO
BACKGROUND AND AIMS: We assessed the effectiveness of switching from intravenous to subcutaneous infliximab in patients with inflammatory bowel diseases (IBDs) treated with or without intensified intravenous regimen. METHODS: In this multicenter observational study, IBD patients in clinical remission (partial Mayo score ≤2 or Harvey-Bradshaw index ≤4) were switched to a unique dose of subcutaneous infliximab (120 mg every other week). Pharmacological and biological data were collected at baseline, visit 1 (4-8 weeks postswitch), visit 2 (8-16 weeks postswitch), and visit 3 (16-24 weeks postswitch). Relapse was defined as clinical relapse or fecal calprotectin increase ≥150 µg/g compared with baseline. RESULTS: Among 184 eligible patients, 72.3% (n = 133 of 184) agreed to switch to subcutaneous infliximab. At visit 3, a relapse occurred in 10.2% (n = 6 of 59), 7.3% (n = 3 of 38), 16.7% (n = 3 of 18), and 66.7% (n = 10 of 15) (P < .001) of patients receiving 5 mg/kg every 8 weeks, 10 mg/kg every 8 weeks, 10 mg/kg every 6 weeks, and 10 mg/kg every 4 weeks, respectively. Dose escalation to 240 mg every other week led to recapture clinical remission in 93.3% (n = 14 of 15). Infliximab serum levels increased after the switch (P < .0001) except for patients receiving 10 mg/kg every 4 weeks. In multivariable analysis, 10 mg/kg every 4 weeks regimen (odds ratio, 12.4; 95% confidence interval, 1.6-98.4; P = .017) and fecal calprotectin >250 µg/g at baseline (odds ratio, 5.4; 95% confidence interval, 1.1-27.6; P = .042) had a higher risk of relapse as well as reduced (41.7%) or stable (36.8%) infliximab serum levels between baseline and visit 1 compared with increased serum levels (12.7%) (P = .020 and P = .019, respectively). Patients' acceptability (10-point scale) was improved by the switch (6.9 ± 1.6 vs 8.6 ± 1.4; P < .0001). No severe adverse event was reported. CONCLUSIONS: Switching from intravenous to subcutaneous infliximab 120 mg every other week is safe and well accepted, leading to a low risk of relapse in IBD patients except for those receiving 10 mg/kg every 4 weeks requiring 240 mg every other week.

BACKGROUND & AIMS: The management of intra-abdominal abscesses complicating Crohn's disease (CD) is challenging, and surgery with delayed intestinal resection is often recommended. The aims of this study were to estimate the success rate of adalimumab (ADA) in patients with CD with an intra-abdominal abscess resolved without surgery, and to identify predictive factors for success. METHODS: A multicenter, prospective study was conducted in biologic-naïve patients with CD with resolved intra-abdominal abscess treated with ADA with a 2-year follow-up. The primary endpoint was ADA failure at week (W) 24 defined as a need for steroids after W12, intestinal resection, abscess recurrence, and clinical relapse. Secondary post-hoc endpoint was the long-term success defined as the survival without abscess relapse or intestinal resection at W104. The factors associated with ADA failure at W24 and W104 were identified using a logistic and a Cox regression, respectively. RESULTS: From April 2013 to December 2017, 190 patients from 27 GETAID centers were screened, and 117 were included in the analysis. Fifty-eight patients (50%) were male, and the median age at baseline was 28 years. At W24, 87 patients (74%; 95% confidence interval [CI], 65.5%-82.0%; n = 117) achieved ADA success. Among the 30 patients with ADA failure, 15 underwent surgery. At W104, the survival rate without abscess recurrence or surgery was 72.9% (95% CI, 62.1%-79.8%; n = 109). Abscess drainage was significantly associated with ADA failure at W24 (odds ratio, 4.18; 95% CI, 1.06-16.5; P =0 .043). Disease duration (hazard ratio [HR], 1.32; 95% CI, 1.09-1.59; P = .008), abscess drainage (HR, 5.59; 95% CI, 2.21-14.15; P = .001), and inflammatory changes in mesenteric fat (HR, 0.4; 95% CI, 0.17-0.94; P = .046) were significantly associated with ADA failure at W104. CONCLUSION: Provided that the abscess was carefully managed before initiating medical treatment, this study showed the high efficacy of ADA in the short and long term in biologic-naïve patients with CD complicated by an intra-abdominal abscess.

BACKGROUND & AIMS: Crohn's disease (CD) patients included in the Tailored Treatment With Infliximab for Active Crohn's Disease (TAILORIX) trial started infliximab in combination with an immunosuppressant for 1 year. The aim of the present study was to determine the long-term disease course beyond the study period. METHODS: We compared the outcomes of patients who did or did not reach the primary end point of the TAILORIX trial, defined as sustained corticosteroid-free clinical remission from weeks 22 through 54, with no ulcers on ileocolonoscopy at week 54. The primary outcome of this follow-up study was the progression-free survival of CD defined by anal or major abdominal surgery, CD-related hospitalization, or the need for a new systemic CD treatment. RESULTS: The 95 patients (median disease duration, 4.5 mo; interquartile range, 1.0-56.6 mo) analyzed, including 45 (47%) who achieved the primary end point, were followed up for a median duration of 64.2 months (interquartile range, 57.6-69.9 mo) after the end of the study period. There was no significant difference in CD progression-free survival at 1, 3, and 5 years between patients who achieved the TAILORIX primary end point and patients who did not (P = .64). No difference was observed between both groups for each component of CD progression: anal surgery, major abdominal surgery, CD-related hospitalization, or the need for a new systemic CD treatment. CONCLUSIONS: Achieving a sustained clinical remission off steroids with complete endoscopic remission in this cohort of 95 patients with early CD was not associated with less disease progression. Prospective trials to define the therapeutic goals that change the natural history of CD and prevent complications are needed.

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.

INTRODUCTION: The objective of this study was to describe the efficacy and safety of infliximab (IFX) reintroduction in Crohn's disease (CD) after stopping for loss of response or intolerance. METHODS: We conducted a prospective multicenter observational cohort study including adult patients with clinically (CD Activity Index >150) and objectively active luminal CD in whom IFX was reintroduced after at least 6 months of discontinuation. The reasons for the initial discontinuation could be a secondary loss of response or IFX intolerance. The reintroduction schedule included 3 IFX infusions at weeks 0, 4, and 8, after a systematic premedication. The primary end point was the efficacy of IFX retreatment at week 26 defined by a CD Activity Index of <150 in the absence of IFX discontinuation or use of corticosteroids, surgery, or other biologic. RESULTS: At week 26, 24 patients (35%) among the 69 analyzed reached the primary end point. No significant difference was observed between rates of clinical remission at week 26 in patients with prior LOR (n = 48) and those with IFX intolerance (n = 21) (35% and 33%, P = 0.87, respectively). Thirty-two acute infusion reactions were recorded in 27 patients, leading to withdrawal of IFX in 20 patients. No pharmacokinetic characteristic at baseline but detection of positive anti-drug antibodies at week 4 was predictive of IFX failure or infusion reaction at week 26. DISCUSSION: In this first prospective cohort study, IFX retreatment was safe and effective in one-third of the patients with CD, regardless the reason of prior discontinuation. Early detection of anti-drug antibodies can predict subsequent IFX reintroduction failure and infusion reactions.

BACKGROUND AND AIMS: In Crohn's disease (CD), a composite therapeutic target was recently recommended, including both objective measurement (endoscopic remission) and Patient-Reported Outcomes (resolution of abdominal pain and normalization of bowel function). All dimensions of health-related quality of life (HRQoL) are impacted: not only bowel symptoms but also systemic symptoms, emotional wellbeing and social function. Thus, understanding the predictors of each HRQoL dimension would improve patient management. However, analysis of these factors has only been found in a few publications, with some limitations. Therefore, this study aimed to explore the evolution of the HRQoL of CD patients during six months after initiation of anti-TNF and to identify its predictors. METHODS: We analyzed data of 56 patients included in a multicenter prospective cohort study (COQC-PIT). HRQoL measures (using IBDQ-32) and data related to patient, disease and treatment characteristics were collected every two months. Generalized estimating equations were used. RESULTS: Overall HRQoL was significantly improved 2 months after anti-TNF initiation, and then stagnated. Patient, disease, and treatment characteristics have differentiated impacts on the overall score and on each dimension of quality of life. Subcutaneous anti-TNF had no significant effect on overall HRQoL, improving only emotional function and bowel symptoms. Concomitant use of corticosteroids and/or immunomodulators impaired almost all dimensions. Having children or working altered bowel symptoms. Disease duration and active smoking negatively impact emotional function and systemic symptoms. CONCLUSIONS: Each HRQoL dimension, not only bowel symptoms, and their influencing factors should therefore be considered in medical decision-making, especially in months following the initiation of a new treatment such as anti-TNF.

BACKGROUND AND OBJECTIVE: Anti-TNFs have been shown to significantly improve the health-related quality of life (HRQoL) in Crohn's disease (CD) patients. The purpose of this study was to investigate to what extend the patients' preferences for these intravenous (IV) and subcutaneous (SC) treatments differ based on respondents' quality of life. An online discrete choice experiment (DCE) was conducted to understand patient trade-offs in treatment choice. METHODS: Fifty-seven Crohn's disease anti-TNF naïve patients were asked to choose between two different scenarios, considering the following attributes: mode of administration (MODE), total availability for injection (TIME), speed of onset (DELAY), risk of anti-TNF administration despite a contraindication (RISK) and total monthly out-of-pocket expenses (COST). At the same time, patients completed the IBDQ-32 questionnaire. Conditional logit models without and with interaction terms were estimated to evaluate attribute weights. RESULTS: Patients preferred to self-administer SC anti-TNF rather than have a primary care nurse do it, whereas the preference for IV route was negative. After adding interaction terms however, the IV route became preferred for patients with impaired HRQoL, this preference having decreased as HRQoL increased. Surprisingly, patients with impaired HRQoL were less willing to spend more time on treatment, and this effect diminished as HRQoL (overall and in each dimension) became higher. CONCLUSIONS: HRQoL level changed patients' preferences for the anti-TNF treatment. The results suggest the need to optimise the management of IV infusions in the hospital and reinforce the importance of patient-reported outcome measures (PROMS) as a common practice to improve shared medical decision making.

INTRODUCTION: There are currently no comparative data on the efficacy and safety of vedolizumab and ustekinumab in ulcerative colitis (UC) after anti-TNF therapy fails. METHODS: We retrieved the full datasets of two observational, multicentre, retrospective studies of patients with UC for whom anti-TNF therapy failed and the patients were then treated with either vedolizumab or ustekinumab. The outcomes included steroid-free clinical remission, clinical remission, treatment persistence, colectomy, hospitalization, and serious and infectious adverse events. Propensity scores weighted comparison was applied. RESULTS: In total, 121 patients were included in the vedolizumab group and 97 were included in the ustekinumab group. At week 14 and week 52, in the weighted cohort, no difference was found between vedolizumab and ustekinumab for steroid-free clinical remission (OR = 0.55 [0.21-1.41], p = .21 and 0.94 [0.40-2.22], p = .89, respectively). There was no difference between vedolizumab and ustekinumab for secondary outcomes such as clinical remission, hospitalization, UC-related surgery, treatment persistence and serious and infectious adverse events. CONCLUSION: In patients with UC for whom anti-TNF therapy failed, no difference was found between vedolizumab and ustekinumab after propensity scores weighted comparison. Further studies are required to determine predictive factors of the efficacy of both biological agents.

BACKGROUND AND AIM: Expression of FimH adhesin by invasive Escherichia coli in the gastrointestinal tract of patients with Crohn's disease (CD) facilitates binding to epithelial glycoproteins and release of pro-inflammatory cytokines. Sibofimloc is a first-in-class FimH blocker that showed little systemic absorption in healthy volunteers. The current study evaluated systemic absorption, safety, and effect on inflammatory biomarkers of sibofimloc in patients with CD. METHODS: This was an open-label, multicenter phase 1b study in adults with active CD. In part 1, two patients received a single oral dose of 3000-mg sibofimloc followed by 1500 mg b.i.d. for 13 days. In part 2, six patients received 1500-mg sibofimloc b.i.d. for 13 days. Blood was drawn for pharmacokinetic and biomarker analysis, and stool was collected for biomarker and microbiome analysis. RESULTS: Eight patients with active ileal or ileocolonic CD were enrolled into the study. Systemic sibofimloc exposure was low. Sibofimloc was well tolerated with only grade 1-2 events observed. Several pro-inflammatory biomarkers, including IL-1ß, IL-6, IL-8, TNF-α, IFN-γ, and calprotectin, were decreased in stool by end of study. CONCLUSIONS: This first study of the novel FimH blocker, sibofimloc, in patients with active CD demonstrated minimal systemic exposure with good tolerance, while decreasing several inflammatory biomarkers. EudraCT number: 2017-003279-70.

BACKGROUND: Iron deficiency (ID) is a frequent condition in patients with inflammatory bowel disease (IBD). AIM: Our aim was to investigate the prevalence of ID in patients with IBD. METHODS: This was a prospective multicenter cross-sectional study conducted in 21 gastroenterology departments in France between January and March 2020. All adult patients with confirmed IBD who were admitted to the hospital were eligible for inclusion. ID was defined as ferritinemia ≤ 100 µg/L in patients with signs of inflammation (C-reactive protein (CRP) ≥ 5 mg/L) or ferritinemia < 30 µg/L in the absence of inflammation. RESULTS: In total, 1036 IBD (685 Crohn's disease and 351 ulcerative colitis) patients (52.1% women) with a mean age of 41.8 ± 15.5 years were recruited. Approximately half of the patients (504, 51.1%) were in disease remission at the time of enrollment. Systematic monitoring of iron status was performed in 12/21 (57%) participating centers, including measurements of ferritin (12/12, 100%), hemoglobin (11/12, 92%), transferrin saturation (TSAT) (6/12, 50.0%), and serum iron (5/12, 42%). About one-fifth of the patients had been treated with intravenous iron (218, 21.0%), whereas only a small percentage received oral iron (36, 3.5%). ID occurred in 97 patients (23.7% CI 95% 19.8-28.1). Patients with moderate/severe IBD activity (OR: 3.66; CI 95% 24.4-61.2; p = 0.007) or concomitant anemia (OR: 3.66; CI 95% 1.97-6.78; p < 0.001) had an increased likelihood of having ID. CONCLUSION: Patients with moderate/severe IBD activity or concomitant anemia are at increased risk of ID. Early detection and management of ID in patients with IBD is recommended.

BACKGROUND AND AIMS: Patients with inflammatory bowel disease have an increased risk of venous thromboembolism (VTE) and cardiovascular disease (CVD). The study aims to determine the prevalence of CVD and VTE risk factors in a large population of patients with ulcerative colitis (UC). METHODS: We conducted a cross-sectional study in 33 French and Belgium referral centers. A questionnaire was developed to explore self-reported risk factors for VTE and CVD, based on the latest international guidelines, in consecutive patients with UC. RESULTS: A total of 1071 patients with UC were included. There were 539 women (50.3%), and the median age of patients was 44 years [32; 57]. The median disease duration was 10 years [6; 17]. In the cohort, 36.5% of patients reported no cardiovascular risk factor (CVRF) and 72% had ≤ 1 CVRF. Regarding cardiovascular risk markers (CVRM) 36.9% of patients reported no CVRM and 78% had ≤ 1 CVRM. Of the 1071 patients, 91.3% of patients reported no VTE strong risk factor and 96% had ≤ 1 VTE moderate risk factor. CONCLUSION: This is the first cohort specifically designed to assess both VTE and CVD risks in patients with UC. More than one third of patients with UC had no CVRF and around three quarters had ≤ 1 CVRF. In addition, more than nine out of ten patients had no VTE strong risk factor and ≤ 1 moderate risk factor. Physicians should be aware of these factors in their patients.

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.

INTRODUCTION: The impact of severity and location of Crohn's disease (CD) endoscopic ulcers on endoscopic remission in patients treated with antitumor necrosis factor is poorly known. We aimed to describe the endoscopic evolution of CD lesions in a prospective cohort of patients treated with infliximab (IFX) in combo therapy. METHODS: We conducted a post hoc analysis of the TAILORIX randomized controlled trial, which studied biologic-naïve patients with active CD and endoscopic ulcers receiving IFX combo therapy. Ileocolonoscopies were performed at week 0, 12, and 54. Endoscopic healing was defined as the absence of ulcers and complete endoscopic remission as CD Endoscopic Index of Severity (CDEIS) <3. Ileocolonic segments were scored separately for remission by blinded readers. RESULTS: A total of 122 (median disease duration: 7 months) patients were included, corresponding with 379 diseased segments. The median (IQR) CDEIS scores at week 0, 12, and 54 were 9.9 (6.1-14.4), 2.4 (0.2-4.6), and 0.2 (0.0-3.7), respectively. At weeks 12 and 54, the rates of endoscopic healing and complete endoscopic remission were 41% and 61% and 61% and 73%, respectively. Median CDEIS scores were similar among patients with deep ulcers at baseline and those with only superficial ulcers at week 12 and 54. Segmental remission rates were lower both at week 12 and 54 in the ileum compared with colonic segments (P < 0.01 all comparisons) and in the rectum (P = 0.02 and P = 0.03). DISCUSSION: In biologic-naive patients with CD treated with IFX combo therapy, the severity of endoscopic lesions at the baseline did not influence healing rates. Endoscopic remission occurs less frequently in the ileum compared with the colon.

OBJECTIVE: Following ileal resection for Crohn's disease (CD), recurrence is very frequent. Although several clinical risk factors of recurrence have been identified, predicting relapse remains challenging. Performing an ileocolonoscopy within the first year after surgery is currently recommended to assess endoscopic recurrence and to adjust the treatment. We took advantage of a large prospective multicentric cohort to investigate the role of the ileal mucosa-associated microbiota in postoperative endoscopic recurrence. PATIENTS AND METHODS: Ileal mucosa-associated microbiota was analysed by 16S sequencing at the time of surgery and/or of endoscopic evaluation in 201 patients (288 samples in total) prospectively recruited in France. RESULTS: Ileal mucosa-associated microbiota exhibits profound changes following surgery in CD. Compared with non-recurrence setting, endoscopic recurrence is associated with strong changes in ileal mucosa-associated microbiota that are highly reminiscent of those observed generally in ileal CD compared with healthy subjects with a reduction in alpha diversity, an increase in several members of the Proteobacteria phylum and a decrease in several members of the Lachnospiraceae and the Ruminococcaceae families within the Firmicutes phylum. At the time of surgery, we identified several bacterial taxa associated with endoscopic recurrence and that can better predict relapse than usual clinical risk factors. CONCLUSION: Surgery has an important impact on ileal mucosa-associated microbiota. Postoperative endoscopic recurrence is associated with changes in microbiota composition and alpha diversity. The gut microbiota has the potential to predict postoperative evolution and recurrence.
