ABSTRACT
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.
ABSTRACT
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: Bevacizumab-a humanized monoclonal antibody-has been widely used to treat patients with hereditary hemorrhagic telangiectasia (HHT), but no randomized trial has yet been conducted. METHODS: This study is a double-blind multicenter randomized phase 2 trial with a 1:1 active-treatment-to-placebo ratio. We included patients over the age of 18 with a confirmed diagnosis and the need for at least four red blood cell (RBC) units transfused in the 3 months before study enrollment. Bevacizumab was administered at a dose of 5 mg/kg every 14 days with a total of six injections. The primary efficacy criterion was a decrease of at least 50% in the cumulative number of RBC units transfused in a 3-month period before and after treatment. RESULTS: A total of 24 patients (12 in each group) were included and randomized at 4 different centers. In intention-to-treat analysis, 63.6% of patients (7/11) in the bevacizumab group versus 33.3% of patients (4/12) in the placebo group decreased the number of blood transfusions by at least 50% (p = 0.22). Hemoglobin levels significantly improved at 6 months in the bevacizumab versus placebo group (p = 0.02). The pharmacokinetics study revealed that patients with high exposure to bevacizumab had a significant decrease in RBC transfusions (p = 0.03). Fifty-nine adverse events were observed, 34 in the placebo arm versus 25 in the bevacizumab arm. CONCLUSION: Though the present trial was underpowered, patients with HHT receiving bevacizumab required numerically fewer red blood cell transfusions than those receiving placebo, particularly those with high exposure.

Therapeutic drug monitoring (TDM) of anti-TNF-α is an important tool in clinical practice for inflammatory diseases. In this study, we have evaluated the performance of several assays for drug and antidrug antibodies (ADA) measurement in the serum. 50 sera from patients treated with infliximab (IFX) and 49 sera from patients treated with adalimumab (ADAL) were monitored with four immunoassays. We have compared Promonitor, i-Track10®, and ez-track1 assays to our gold standard Lisa Tracker® ELISA using Cohen's kappa, Passing-Bablok, and Bland-Altman analysis. The qualitative analysis evaluated by Cohen's kappa values found for IFX measurements an "almost perfect" concordance for Promonitor, "moderate" for i-Track10® and "substantial" for ez-Track1. For ADAL, kappa values were "moderate" for all tested methods. For anti-IFX, kappa values were "almost perfect" for Promonitor, "fair" for i-Track10®, and "substantial" for ez-Track1. For anti-ADAL, kappa values were "almost perfect" for all three assays. For quantitative analysis of drug measurements, Pearson's r values were all above 0.9 and Lin's concordance coefficients of all immunoassays were around 0.80. Performances of the four evaluated immunoassays were acceptable for TDM based on our laboratory experience. Nevertheless, concordance between the four methods for IFX measurement was not perfect and we recommend the use of the same assay for the follow-up of a given patient. The performances of the four immunoassays evaluated were similar and are acceptable for TDM based on our laboratory experience.

BACKGROUND & AIMS: Medico-economic data of patients suffering from chronic nausea and vomiting are lacking. In these patients, gastric electrical stimulation (GES) is an effective, but costly treatment. The aim of this study was to assess the efficacy, safety and medico-economic impact of Enterra therapy in patients with chronic medically refractory nausea and vomiting. METHODS: Data were collected prospectively from patients with medically refractory nausea and/or vomiting, implanted with an Enterra device and followed for two years. Gastrointestinal quality of life index (GIQLI) score, vomiting frequency, nutritional status and safety were evaluated. Direct and indirect expenditure data were prospectively collected in diaries. RESULTS: Complete clinical data were available for142 patients (60 diabetic, 82 non-diabetic) and medico-economic data were available for 96 patients (36 diabetic, 60 non-diabetic), 24 months after implantation. GIQLI score increased by 12.1 ± 25.0 points (p < .001), with a more significant improvement in non-diabetic than in diabetic patients (+15.8 ± 25.0 points, p < .001 versus 7.3 ± 24.5 points, p = .027, respectively). The proportion of patients vomiting less than once per month increased by 25.5% (p < .001). Hospitalisations, time off work and transport were the main sources of costs. Enterra therapy decreased mean overall healthcare costs from 8873 US$ to 5525 US$ /patient/year (p = .001), representing a saving of 3348 US$ per patient and per year. Savings were greater for diabetic patients (4096 US$ /patient/year) than for non-diabetic patients (2900 US$ /patient/year). CONCLUSIONS: Enterra therapy is an effective, safe and cost-effective option for patients with refractory nausea and vomiting. CLINICALTRIALS: gov Identifier: NCT00903799.

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.

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 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: There have been conflicting results from trials of gastric electrical stimulation (GES) for treatment of refractory vomiting, associated or not with gastroparesis. We performed a large, multicenter, randomized, double-blind trial with crossover to study the efficacy of GES in patients with refractory vomiting, with or without gastroparesis. METHODS: For 4 months, we assessed symptoms in 172 patients (66% women; mean age ± standard deviation, 45 ± 12 years; 133 with gastroparesis) with chronic (>12 months) of refractory vomiting (idiopathic, associated with a type 1 or 2 diabetes, or postsurgical). A GES device was implanted and left unactivated until patients were randomly assigned, in a double-blind manner, to groups that received 4 months of stimulation parameters (14 Hz, 5 mA, pulses of 330 µs) or no stimulation (control); 149 patients then crossed over to the other group for 4 months. Patients were examined at the end of each 4-month period (at 5 and 9 months after implantation). Primary endpoints were vomiting score, ranging from 0 (daily vomiting) to 4 (no vomiting), and the quality of life, assessed by the Gastrointestinal Quality of Life Index scoring system. Secondary endpoints were changes in other digestive symptoms, nutritional status, gastric emptying, and control of diabetes. RESULTS: During both phases of the crossover study, vomiting scores were higher in the group with the device on (median score, 2) than the control group (median score, 1; P < .001), in diabetic and nondiabetic patients. Vomiting scores increased significantly when the device was ON in patients with delayed (P < .01) or normal gastric emptying (P = .05). Gastric emptying was not accelerated during the ON period compared with the OFF period. Having the GES turned on was not associated with increased quality of life. CONCLUSIONS: In a randomized crossover study, we found that GES reduced the frequency of refractory vomiting in patients with and without diabetes, although it did not accelerate gastric emptying or increase of quality of life.

Alcohol abstinence before liver transplantation (LT) for alcohol-associated liver disease (ALD) is required for every candidate. Some listed patients might relapse, resulting in LT for patients nonabstinent during the pretransplant period. Long-term survival outcomes of these patients have never been studied. We sought to determine whether alcohol consumption on the day of the LT influenced long-term survival after LT. We conducted a retrospective case-control study among French LT centers. Cases were defined as recipients between January 1995 and December 2007 having positive blood and/or urine alcohol levels the day of LT. Each case was paired with 2 controls corresponding to patients transplanted for ALD during the same trimester. Patients were classified into 3 categories per alcohol consumption: abstainers, occasional or transitory excessive consumers, or patients with a sustained excessive consumption (daily consumption >20-30 g/day). During the study period, 3052 LTs for ALD were conducted in France. We identified 42 cases paired with 84 controls. Median blood alcohol level was 0.4 g/L (range 0.1-4.1 g/L) and median urine alcohol level was 0.2 g/L (range 0.1-2.0 g/L). Median follow-up period until death or censoring was 12.9 years (CI95% = [12.3; 13.6]). Long-term survival was not different between the groups. Relapse to any alcohol consumption rate was higher in the case group (59.5%) than in the control group (38.1%, odds ratio 2.44; CI95% = [1.13; 5.27]), but sustained excessive consumption was not significantly different between the groups (33.3% versus 29.8% in case and control groups respectively, χ2 = 0.68). Rates of recurrent cirrhosis and cirrhosis-related deaths were more frequent in the case group. Liver transplantation for nonabstinent patients during the immediate pretransplant period does not result in impaired long-term survival despite higher relapse and recurrent cirrhosis rates.

BACKGROUND: Telemedicine has shown promising results in the follow up of patients with inflammatory bowel disease. This study compared quality of life and disease activity in patients with inflammatory bowel disease monitored using a telemedicine platform versus standard care. METHODS: In this prospective multicenter study, patients with active inflammatory bowel disease were randomized to EasyMICI-MaMICI® telemedicine platform or standard care. The main objective was to assess the efficacy of the software platform, as measured by quality of life and quality of care. Secondary outcomes were changes in the use of healthcare resources, and patient satisfaction in the MaMICI group. RESULTS: Fifty-four patients were enrolled (November 2017-June 2018); 59.3% had Crohn's disease and 40.7% ulcerative colitis. Forty-two patients received biologics at inclusion. After 12 months, a significant improvement in quality of life was observed with MaMICI versus standard care, with mean (standard deviation) changes from baseline of 14.8 (11.8) vs 6.3 (9.7) in the SIBDQ scores and 18.5 (18.7) vs 2.4 (8.3) in the EuroQol 5 D-3L questionnaire scores (both p ≤ .02). Disease activity was similar in both treatment groups. Use of MaMICI slightly reduced healthcare utilization versus controls (mean gastroenterologist consultations 2.2 vs 4.1; p = .1308). Overall satisfaction with MaMICI was high (mean score 7/10), and 46.2% of remaining patients in the MaMICI group continued to use the platform until 12 months. CONCLUSION: Significant improvement in quality of life and overall satisfaction with this telemedicine platform, indicates that further evaluation of EasyMICI-MaMICI in larger numbers of patients with inflammatory bowel disease is warranted.

BACKGROUND & AIMS: It is a challenge to manage patients with ulcerative proctitis (UP) refractory to standard therapy. We investigated the effectiveness of tumor necrosis factor (TNF) antagonists in a large cohort of patients with refractory UP. METHODS: We conducted a nationwide retrospective cohort study of 104 consecutive patients with active UP refractory to conventional therapies, treated at 1 of 15 centers in France or 1 center in Belgium (the GETAID cohort). Patients received at least 1 injection of anti-TNF (infliximab, adalimumab, golimumab) from October 2006 through February 2017. Clinical response was defined as significant improvement in UC-related symptoms, and remission as complete disappearance of UC-related symptoms, each determined by treating physicians. We collected demographic, clinical, and treatment data. The median duration of follow-up was 24 months (interquartile range, 13-51 months). The primary outcome was clinical response of UP to anti-TNF treatment. RESULTS: Overall, 80 patients (77%) had a clinical response to anti-TNF therapy and 52 patients (50%) achieved clinical remission. Extra-intestinal manifestations (odds ratio OR, 0.24; 95% CI, 0.08-0.7), ongoing treatment with topical steroids (OR, 0.14; 95% CI, 0.03-0.73), and ongoing treatment with topical 5-aminosalycilates (OR, 0.21; 95% CI, 0.07-0.62) were significantly associated with the absence of clinical remission. Sixty percent (38/63) of the patients who had endoscopic assessment during follow up had mucosal healing. Among the overall population (n = 104), the cumulative probabilities of sustained clinical remission were 87.6% ± 3.4% at 1 year and 74.7% ± 4.8% at 2 years. CONCLUSIONS: In a retrospective study of 104 patients with refractory UP, anti-TNF therapy induced clinical remission in 50% and mucosal healing in 60%. About two thirds of the patients were still receiving anti-TNF therapy at 2 years.

BACKGROUND & AIMS: Vedolizumab is used to treat patients with ulcerative colitis (UC), although there is a delay before it is effective. Induction therapy with a calcineurin inhibitor (cyclosporine or tacrolimus) in combination with vedolizumab as maintenance therapy could be an option for patients with an active steroid-refractory UC. We assessed the efficacy and safety of this combination. METHODS: We performed a retrospective observational study, collecting data from 12 referral centers in France that were included in the Groupe d'Etude Thérapeutique des Affections Inflammatoires du tube Digestif. We collected information on 39 patients with an active steroid-refractory UC (31 with active severe UC and 36 failed by treatment with a tumor necrosis factor antagonist) who received a calcineurin inhibitor as induction therapy along with vedolizumab as maintenance therapy. Inclusion date was the first vedolizumab infusion. The outcomes were survival without colectomy, survival without vedolizumab discontinuation, and safety. RESULTS: After a median follow-up period of 11 months, 11 patients (28%) underwent colectomy. At 12 months, 68% of the patients survived without colectomy (95% CI, 53%-84%) and 44% survived without vedolizumab discontinuation (95% CI, 27%-61%). No deaths occurred and 4 severe adverse events were observed. CONCLUSIONS: In a retrospective analysis of 39 patients with an active steroid-refractory UC (most refractory to a tumor necrosis factor antagonist), we found that initial treatment with a calcineurin inhibitor in combination with vedolizumab allowed more than two thirds of patients to avoid colectomy. Further studies are needed to assess the safety of this strategy.

OBJECTIVE: The efficacy of anti-tumour necrosis factors (anti-TNFs) in patients with Crohn's disease (CD) and symptomatic small bowel stricture (SSBS) is controversial. The aim of this study was to estimate the efficacy of adalimumab in these patients and to identify the factors predicting success. DESIGN: We performed a multicentre, prospective, observational cohort study in patients with CD and SSBS. The included patients underwent magnetic resonance enterography at baseline and subsequently received adalimumab. The primary endpoint was success at week 24, defined as adalimumab continuation without prohibited treatment (corticosteroids after the eight week following inclusion, other anti-TNFs), endoscopic dilation or bowel resection. The baseline factors independently associated with success were identified using a logistic regression model, leading to a simple prognostic score. Secondary endpoints were prolonged success after week 24 (still on adalimumab, without dilation nor surgery) and time to bowel resection in the whole cohort. RESULTS: From January 2010 to December 2011, 105 patients were screened and 97 were included. At week 24, 62/97 (64%) patients had achieved success. The prognostic score defined a good prognosis group with 43/49 successes, an intermediate prognosis group with 17/28 successes and a poor prognosis group with 1/16 successes. After a median follow-up time of 3.8â years, 45.7%±6.6% (proportion±SE) of patients who were in success at week 24 (ie, 29% of the whole cohort) were still in prolonged success at 4â years. Among the whole cohort, 50.7%±5.3% of patients did not undergo bowel resection 4â years after inclusion. CONCLUSIONS: A successful response to adalimumab was observed in about two-thirds of CD patients with SSBS and was prolonged in nearly half of them till the end of follow-up. More than half of the patients were free of surgery 4â years after treatment initiation. CLINICAL TRIAL REGISTRATION NUMBER: NCT01183403; Results.

BACKGROUND & AIMS: Little is known about long-term outcomes of patients with Crohn's disease (CD) after infliximab withdrawal. We aimed to describe the long-term outcomes of patients with CD in clinical remission after infliximab treatment was withdrawn. METHODS: We performed a retrospective analysis of data from the 115 patients included in the infliximab discontinuation in patients with CD in stable remission on combined therapy with antimetabolites (STORI) study, performed at 20 centers in France and Belgium from March 2006 through December 2009. The STORI cohort was a prospective analysis of risk and factors associated with relapse following withdrawal of maintenance therapy with infliximab, maintained on antimetabolites, while in clinical remission. We collected data from the end of the study until the last available follow-up examination on patient surgeries, new complex perianal lesions (indicating major complications), and need for and outcomes of restarting therapy with infliximab or another biologic agent. The de-escalation strategy was considered to have failed when a major complication or infliximab restart failure occurred. RESULTS: Of the 115 patients initially included, data from 102 patients (from 19 of the 20 study centers) were included in the final analysis. The median follow-up time was 7 years. Twenty-one percent of the patients did not restart treatment with infliximab or another biologic agent and did not have a major complication 7 years after infliximab withdrawal (95% CI, 13.1-30.3). Among patients who restarted infliximab, treatment failed for 30.1% 6 years after restarting (95% CI, 18.5-42.5). Overall, at 7 years after stopping infliximab therapy, major complications occurred in 18.5% of patients (95% CI, 10.2-26.8) whereas 70.2% of patients had no failure of the de-escalation strategy (95% CI, 60.2-80.1). Factors independently associated with major complications were upper-gastrointestinal location of disease, white blood cell count ≥ 5.0 × 109/L, and hemoglobin level ≤12.5 g/dL at the time of infliximab withdrawal. Patients with at least 2 of these factors had a more than 40% risk of major complication in the 7 years following infliximab withdrawal. CONCLUSIONS: In a long-term follow-up of the STORI cohort (7 years) one fifth of the patients did not restart infliximab or another biologic agent and did not develop major complications. Seventy percent of patients had no failure of the de-escalation strategy (no major complication and no failure of infliximab restart).

BACKGROUND & AIMS: Phase 3 trials have shown the efficacy of vedolizumab, which binds to integrin α4ß7, in patients with Crohn's disease (CD) or ulcerative colitis (UC). We investigated the effectiveness and safety of vedolizumab in patients who failed anti-tumor necrosis factor therapy. METHODS: From June through December 2014, there were 173 patients with CD and 121 patients with UC who were included in a multicenter nominative compassionate early access program granted by French regulatory agencies. This program provided patients with access to vedolizumab before it was authorized for marketing. Vedolizumab (300 mg) was administered intravenously at weeks 0, 2, and 6, and then every 8 weeks. Disease activity was assessed using the Harvey-Bradshaw Index for CD and the partial Mayo Clinic score for UC. We report results obtained after the 14-week induction phase. RESULTS: Among the 294 patients treated with vedolizumab (mean age, 39.5 ± 14.0 y; mean disease duration, 10.8 ± 7.6 y; concomitant steroids, 44% of cases), 276 completed the induction period, however, 18 discontinued vedolizumab because of a lack of response (n = 14), infusion-related reaction (n = 2), or infections (n = 2). At week 14, 31% of patients with CD were in steroid-free clinical remission and 51% had a response; among patients with UC, 36% were in steroid-free clinical remission and 50% had a response. No deaths were reported. Severe adverse events occurred in 24 patients (8.2%), including 15 (5.1%) that led to vedolizumab discontinuation (1 case of pulmonary tuberculosis and 1 rectal adenocarcinoma). CONCLUSIONS: In a cohort of patients with CD or UC who failed previous anti-tumor necrosis factor therapy, approximately one third of patients achieved steroid-free clinical remission after 14 weeks of induction therapy with vedolizumab. This agent had an acceptable safety profile in these patients.

BACKGROUND & AIMS: Colonic strictures complicate inflammatory bowel disease (IBD) and often lead to surgical resection to prevent dysplasia or cancer. We assessed the frequency of dysplasia and cancer among IBD patients undergoing resection of a colorectal stricture. METHODS: We analyzed data from the Groupe d'études et thérapeutiques des affections inflammatoires du tube digestif study. This was a nationwide retrospective study of 12,013 patients with IBD in France who underwent surgery for strictures at 16 centers from August 1992 through January 2014 (293 patients for a colonic stricture, 248 patients with Crohn's disease, 51% male, median age at stricture diagnosis of 38 years). Participants had no preoperative evidence of dysplasia or cancer. We collected clinical, endoscopic, surgical, and pathology data and information on outcomes. RESULTS: When patients were diagnosed with strictures, they had IBD for a median time of 8 years (3-14). The strictures were a median length of 6 cm (4-10) and caused symptoms in 70% of patients. Of patients with Crohn's disease, 3 (1%) were found to have low-grade dysplasia, 1 (0.4%) was found to have high-grade dysplasia, and 2 (0.8%) were found to have cancer. Of patients with ulcerative colitis, 1 (2%) had low-grade dysplasia, 1 (2%) had high-grade dysplasia, and 2 (5%) had cancer. All patients with dysplasia or cancer received curative surgery, except 1 who died of colorectal cancer during the follow-up period. No active disease at time of surgery was the only factor associated with dysplasia or cancer at the stricture site (odds ratio, 4.86; 95% confidence interval, 1.11-21.27; P = .036). CONCLUSIONS: In a retrospective study of patients with IBD undergoing surgery for colonic strictures, 3.5% were found to have dysplasia or cancer. These findings can be used to guide management of patients with IBD and colonic strictures.

OBJECTIVE: Coexistence of ANCA-associated vasculitis (AAV) and IBD is a rare condition that is rarely described in the literature. The aim of the study was to describe the main characteristics of patients presenting with both IBD and AAV. METHODS: A retrospective study of AAV patients in the French Vasculitis Study Group cohort who also had a diagnosis of IBD was conducted. We reviewed the medical records and outcomes of these patients. RESULTS: We identified 11 patients with AAV and IBD. Four patients with eosinophilic granulomatosis with polyangiitis (Churg-Strauss) also had ulcerative colitis and seven patients with granulomatosis with polyangiitis (GPA) had Crohn's disease. No Crohn's disease was observed in eosinophilic GPA and no ulcerative colitis in GPA. IBD started before AAV manifestations in six cases, simultaneously in two cases and after AAV manifestations in three cases. CONCLUSION: Coexistence of IBD and AAV is a rare condition. The therapeutic management of these patients includes corticosteroids in all cases and immunosuppressive drugs in some patients. Coexistence of IBD and AAV might be explained by common underlying inflammatory responses and cytokine profiles polarized towards either Th1 or Th2. Finally, in the presence of digestive manifestations in the context of AAV, the hypothesis of IBD should be assessed.
