Targeted surgery combined with postoperative medical therapy for residual disease for severe and multifocal Crohn disease.

BACKGROUND: In patients with multifocal intestinal Crohn disease requiring surgery for complication or uncontrolled disease, resection of all the lesions may lead to diarrhea and malnutrition. METHODS: This is a single-center retrospective review of all patients undergoing targeted surgery for multifocal Crohn disease with at least one residual Crohn disease location left behind. The primary endpoint was the rate of insufficient control of residual Crohn disease lesions requiring redo-surgery targeting these lesions. The rate of clinical remission defined by Harvey-Bradshaw index <4 was studied over time. RESULTS: From January 2012 to August 2022, among 320 patients undergoing surgery for intestinal Crohn disease, 30 met all criteria. Before surgery, patients had received a mean of 3 medical treatment lines; 83% (n = 25) had a clinically active Crohn disease (Harvey-Bradshaw index ≥4). Surgery consisted in ileocolonic (n = 14;47%), small bowel (n = 5;17%) or colonic resection (n = 12;40%) and strictureplasty (n = 4;13%). Operative mortality was nil. Overall postoperative and severe morbidity rates were 15 of 30 (50%) and 3 of 30. Residual lesions were in the small bowel (n = 15;50%), the colon (n = 16;53%), and/or the rectum (n = 16;53%). Twenty-five patients (83%) had postoperative medical therapy. Median follow-up was 65. Six patients (20%) required reoperation for insufficient control of residual lesions at index surgery after a mean of 98 ± 8 months. The clinical remission rate increased from 17% before surgery to 59% at 6-12 months and 71% at 24 months. CONCLUSION: In patients with multifocal Crohn disease, surgery targeted to severe and complicated lesions combined with postoperative medical treatment is a safe and effective strategy.

Tuberculosis and Immune Reconstitution Inflammatory Syndrome in Patients With Inflammatory Bowel Disease and Anti-TNFα Treatment: Insights From a French Multicenter Study and Systematic Literature Review With Emphasis on Paradoxical Anti-TNFα Resumption.

Background: The advent of anti-tumor necrosis factor α (anti-TNFα) has revolutionized the treatment of inflammatory bowel disease (IBD). However, susceptibility to active tuberculosis (TB) is associated with this therapy and requires its discontinuation. The risk of immune reconstitution inflammatory syndrome (IRIS) in this population is poorly understood, as is the safety of resuming anti-TNFα. Methods: This French retrospective study (2010-2022) included all TB cases in patients with IBD who were treated with anti-TNFα in 6 participating centers. A systematic literature review was performed on TB-IRIS and anti-TNFα exposure. Results: Thirty-six patients were included (median age, 35 years; IQR, 27-48). TB was disseminated in 86% and miliary in 53%. IRIS occurred in 47% after a median 45 days (IQR, 18-80). Most patients with TB-IRIS (93%) had disseminated TB. Miliary TB was associated with IRIS risk in univariate analysis (odds ratio, 7.33; 95% CI, 1.60-42.82; P = .015). Anti-TB treatment was longer in this population (median [IQR], 9 [9-12] vs 6 [6-9] months; P = .049). Anti-TNFα was resumed in 66% after a median 4 months (IQR, 3-10) for IBD activity (76%) or IRIS treatment (24%), with only 1 case of TB relapse. Fifty-two cases of TB-IRIS in patients treated with anti-TNFα were reported in the literature, complicating disseminating TB (85%) after a median 42 days (IQR, 21-90), with 70% requiring anti-inflammatory treatment. Forty cases of TB-IRIS or paradoxical reaction treated with anti-TNFα were also reported. IRIS was neurologic in 64%. Outcome was mostly favorable (93% recovery). Conclusions: TB with anti-TNFα treatment is often complicated by IRIS of varying severity. Restarting anti-TNFα is a safe and effective strategy.

Rates of Adverse Events in Patients With Ulcerative Colitis Undergoing Colectomy During Treatment With Tofacitinib vs Biologics: A Multicenter Observational Study.

INTRODUCTION: Patients with ulcerative colitis (UC) receiving immunosuppressive drugs are at substantial risk of colectomy. We aimed to assess the risk of postoperative complications of tofacitinib exposure before colectomy in comparison with biologics. METHODS: A multicenter, retrospective, observational study was conducted in patients with UC who underwent total colectomy for medically refractory disease, exposed to tofacitinib or a biologic before surgery. Primary outcome was the occurrence of any complication within 30 (early) and 90 (late) days after surgery. Secondary outcomes were the occurrence of infections, sepsis, surgical site complications, venous thromboembolic events (VTE), hospital readmissions, and redo surgery within the same timepoints. RESULTS: Three hundred one patients (64 tofacitinib, 162 anti-tumor necrosis factor-α agents, 54 vedolizumab, and 21 ustekinumab) were included. No significant differences were reported in any outcome, except for a higher rate of early VTE with anti-tumor necrosis factor-α agents ( P = 0.047) and of late VTE with vedolizumab ( P = 0.03). In the multivariate analysis, drug class was not associated with a higher risk of any early and late complications. Urgent colectomy increased the risk of any early (odds ratio [OR] 1.92, 95% confidence interval [CI] 1.06-3.48) complications, early hospital readmission (OR 4.79, 95% CI 1.12-20.58), and early redo surgery (OR 7.49, 95% CI 1.17-47.85). A high steroid dose increased the risk of any early complications (OR 1.96, 95% CI 1.08-3.57), early surgical site complications (OR 2.03, 95% CI 1.01-4.09), and early redo surgery (OR 7.52, 95% CI 1.42-39.82). Laparoscopic surgery decreased the risk of any early complications (OR 0.54, 95% CI 0.29-1.00), early infections (OR 0.39, 95% CI 0.18-0.85), and late hospital readmissions (OR 0.34, 95% CI 0.12-1.00). DISCUSSION: Preoperative tofacitinib treatment demonstrated a postoperative safety profile comparable with biologics in patients with UC undergoing colectomy.

Discontinuation of Anti-Tumour Necrosis Factor Therapy in Patients with Perianal Fistulizing Crohn's Disease: Individual Participant Data Meta-Analysis of 309 Patients from 12 Studies.

BACKGROUND: The risk of relapse after anti-tumour necrosis factor [TNF] therapy discontinuation in Crohn's disease patients with perianal fistulas [pCD] is unclear. We aimed to assess this risk. METHODS: A systematic literature search was conducted to identify cohort studies on the incidence of relapse following anti-TNF discontinuation in pCD patients. Individual participant data were requested from the original study cohorts. Inclusion criteria were age ≥16 years, pCD as a (co)indication for start of anti-TNF therapy, more than three doses, and remission of luminal and pCD at anti-TNF discontinuation. The primary outcome was the cumulative incidence of CD relapse using Kaplan-Meier estimates. Secondary outcomes included response to re-treatment and risk factors associated with relapse as assessed by Cox regression analysis. RESULTS: In total, 309 patients from 12 studies in ten countries were included. The median duration of anti-TNF treatment was 14 months [interquartile range 5.8-32.5]. Most patients were treated for pCD without active luminal disease [89%], received first-line anti-TNF therapy [87%], and continued immunomodulatory therapy following anti-TNF discontinuation [78%]. The overall cumulative incidence of relapse was 36% (95% confidence interval [CI] 25-48%) and 42% [95% CI 32-53%] at 1 and 2 years after anti-TNF discontinuation, respectively. Risk factors for relapse included smoking (hazard ratio [HR] 1.5 [1.0, 2.1]) and history of proctitis (HR 1.7 [1.1, 2.5]). The overall re-treatment response rate was 82%. CONCLUSIONS: This individual participant data meta-analysis, on predominantly patients with pCD without active luminal disease and first-line anti-TNF therapy, shows that over half of patients remain in remission 2 years after anti-TNF discontinuation. Therefore, anti-TNF discontinuation may be considered in this subgroup.

Tofacitinib for Patients with Anti-TNF Refractory Ulcerative Proctitis: A Multicentre Cohort Study from the GETAID.

BACKGROUND: Although ulcerative proctitis [UP] can dramatically impair quality of life, treatment efficacy has been poorly investigated in UP as it was historically excluded from phase 2/3 randomised controlled trials in ulcerative colitis. Our aim was to assess the effectiveness and safety of tofacitinib for the treatment of UP. METHODS: We conducted a retrospective, multicentre study in 17 GETAID centres, including consecutive patients with UP treated with tofacitinib. The primary endpoint was steroid-free remission between Week 8 and Week 14, defined as a partial Mayo score of 2 [and no individual subscore above 1]. Secondary outcomes included clinical response and steroid-free remission after induction and at 1 year. RESULTS: All the 35 enrolled patients previously received anti-tumour necrosis factor [TNF] therapy and 88.6% were exposed to at least two lines of biologics. At baseline, the median partial Mayo score was 7 (intequartile range [IQR] [5.5-7]). After induction [W8-W14], 42.9% and 60.0% of patients achieved steroid-free remission and clinical response, respectively. At 1 year, the steroid-free clinical remission and clinical response rates were 39.4% and 45.5%, respectively, and 51.2% [17/33] were still receiving tofacitinib treatment. Survival without tofacitinib withdrawal was estimated at 50.4% (95% confidence interval [CI] [35.5-71.6]) at 1 year. Only a lower partial Mayo at baseline was independently associated with remission at induction (0dds ratio [OR] = 0.56 for an increase of 1, (95% CI [0.33-0.95], p = 0.03). Five [14.3%] adverse events were reported, with one leading to treatment withdrawal [septic shock secondary to cholecystitis]. CONCLUSION: Tofacitinib may offer a therapeutic option for patients with refractory UP.

Gastric microbiota in patients with gastric MALT lymphoma according to Helicobacter pylori infection.

BACKGROUND: Gastric Mucosa Associated Lymphoid Tissue lymphoma (GML) development is triggered by Helicobacter pylori (H. pylori) infection. Little is known about the impact of H. pylori infection on gastric microbiota. METHODS: The gastric microbiota was retrospectively investigated using 16S rRNA gene sequencing in 32 patients with untreated GML (10 H. pylori-positive and 22 H. pylori-negative), 23 with remitted and 18 refractory GML and 35 controls. Differences in microbial diversity, bacterial composition and taxonomic repartition were assessed. RESULTS: There was no change in diversity and bacterial composition between GML and control patients taking into account H. pylori status. Differential taxa analysis identified specific changes associated with H. pylori-negative GML: the abundances of Actinobacillus, Lactobacillus and Chryseobacterium were increased while the abundances of Veillonella, Atopobium, Leptotrichia, Catonella, Filifactor and Escherichia_Shigella were increased in control patients. In patients with remitted GML, the genera Haemophilus and Moraxella were significantly more abundant than in refractory patients, while Atopobium and Actinomyces were significantly more abundant in refractory patients. CONCLUSION: Detailed analysis of the gastric microbiota revealed significant changes in the bacterial composition of the gastric mucosa in patients with GML that may have a role in gastric lymphomagenesis but not any new pathobionts.

Dietary index based on the Food Standards Agency nutrient profiling system and risk of Crohn's disease and ulcerative colitis.

BACKGROUND: Nutri-score is now widely available in food packages in Europe. AIM: To study the overall nutritional quality of the diet in relation to risks of Crohn's disease (CD) and ulcerative colitis (UC), in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort METHODS: We collected dietary data at baseline from validated food frequency questionnaires. We used a dietary index based on the UK Food Standards Agency modified nutrient profiling system (FSAm-NPS-DI) underlying the Nutri-Score label, to measure the nutritional quality of the diet. We estimated the association between FSAm-NPS-DI score, and CD and UC risks using Cox models stratified by centre, sex and age; and adjusted for smoking status, BMI, physical activity, energy intake, educational level and alcohol intake. RESULTS: We included 394,255 participants (68.1% women; mean age at recruitment 52.1 years). After a mean follow-up of 13.6 years, there were 184 incident cases of CD and 459 incident cases of UC. Risk of CD was higher in those with a lower nutritional quality, that is higher FSAm-NPS-DI Score (fourth vs. first quartile: aHR: 2.04, 95% CI: 1.24-3.36; p-trend: <0.01). Among items of the FSAm-NPS-DI Score, low intakes of dietary fibre and fruits/vegetables/legumes/nuts were associated with higher risk of CD. Nutritional quality was not associated with risk of UC (fourth vs. first quartile of the FSAm-NPS-DI Score: aHR: 0.91, 95% CI: 0.69-1.21; p-trend: 0.76). CONCLUSIONS: A diet with low nutritional quality as measured by the FSAm-NPS-DI Score is associated with a higher risk of CD but not UC.

Lymphoma In Patients With Inflammatory Bowel Disease: A Multicenter Collaborative Study Between Getaid And Lysa.

BACKGROUND: IBD is associated with an increased risk of developing lymphoma. Although recent data clarifies lymphoma epidemiology in IBD patients, clinical and pathological characteristics of lymphoma occurring in IBD remain ill-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 3 most frequent lymphoma subtypes occurring in IBD. We performed a multicentric case-control study. Controls (lymphoma de novo) were matched (5:1) to cases on gender, age at diagnosis, lymphoma subtype, year of diagnosis, IPI/FLIPI indexes. Overall survival (OS) and progression free survival were compared between cases and controls. RESULTS: 133 IBD patients with lymphoma were included (males = 62.4 %, median age at lymphoma diagnosis = 49 years in males ; 42 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). CONCLUSION: Lymphomas occurring in IBD patients do not seem to have a worse outcome than in patients without IBD. Due to the scarcity of this situation, those patients should be managed in expert centers.

Prevalence of and Factors Associated With Extraintestinal Manifestations and Their Remission in Inflammatory Bowel Disease: The EXTRA-Intestinal Manifestation Prospective Study From the Groupe d'Etude Thérapeutique des Affections Inflammatoires du Tube Digestif.

INTRODUCTION: Extraintestinal manifestations (EIMs) of inflammatory bowel disease (IBD) are challenging clinical situation. No prospective study assessed remission risk factors of EIMs. The aim of this study was to prospectively investigate the epidemiology, risk factors of EIM occurrence, and EIM remission in a large IBD cohort. METHODS: We conducted a cross-sectional study in 30 French referral centers. Between May 2021 and June 2021, all consecutive patients attending to hospital appointment were systematically invited to fill out a questionnaire. RESULTS: A total of 1,971 consecutive patients with IBD were analyzed. There were 1,056 women (53.8%), and the median age of patients was 41 years (31-54). The median disease duration was 11 years (1-18). Overall, 544 (27.6%) had at least 1 EIM. In 20.2% of cases, patients had multiple EIMs. The most frequent EIMs were rheumatological (19%) and dermatological (10%) manifestations. Immunosuppressant treatment (odds ratio [OR] = 2.56; P < 0.001) was a risk factor of EIM, while the Montreal A3 classification (OR = 0.61, P = 0.023) and male gender (OR = 0.61, P < 0.001) were associated with a lower risk of EIM occurrence. IBD current clinical remission (OR = 2.42; P < 0.001) and smoking cessation (OR = 2.98; P < 0.001) were associated factors of EIM remission. Conversely, age at IBD diagnosis (OR = 0.98; P < 0.018) was associated with a lower risk of EIM remission. DISCUSSION: One quarter of patients had at least 1 EIM. Beyond factors associated with the presence of EIMs, patients with IBD current clinical remission and smoking cessation are more likely to achieve EIM remission, while increasing age at IBD diagnosis is associated with decreased chance of remission.

Obesity in adult patients with inflammatory bowel disease: Clinical features and impact on disability. A cross-sectional survey from the GETAID.

BACKGROUND: In recent years, an increasing prevalence of obesity in inflammatory bowel disease (IBD) has been observed. However, only a few studies have focused on the impact of overweight and obesity on IBD-related disability. AIMS: To identify the factors associated with obese and overweight patients with IBD, including IBD-related disability. PATIENTS AND METHODS: In this cross-sectional study, we included 1704 consecutive patients with IBD in 42 centres affiliated with the Groupe d'Etude Therapeutique des Affections Inflammatoires du tube Digestif (GETAID) using a 4-page questionnaire. Factors associated with obesity and overweight were assessed using univariate and multivariate analyses (odds ratios (ORs) are provided with 95% confidence intervals). RESULTS: The prevalence rates of overweight and obesity were 24.1% and 12.2%, respectively. Multivariable analyses were stratified by age, sex, type of IBD, clinical remission and age at diagnosis of IBD. Overweight was significantly associated with male sex (OR = 0.52, 95% CI [0.39-0.68], p < 0.001), age (OR = 1.02, 95% CI [1.01-1.03], p < 0.001) and body image subscore (OR = 1.15, 95% CI [1.10-1.20], p < 0.001) (Table 2). Obesity was significantly associated with age (OR = 1.03, 95% CI [1.02-1.04], p < 0.001), joint pain subscore (OR = 1.08, 95% CI [1.02-1.14], p < 0.001) and body image subscore (OR = 1.25, 95% CI [1.19-1.32], p < 0.001) (Table 3). CONCLUSION: The increasing prevalence of overweight and obesity in patients with IBD is associated with age and poorer body image. A holistic approach to IBD patient care should be encouraged to improve IBD-related disability and to prevent rheumatological and cardiovascular complications.

Preoperative Predictors of Neoplasia in Patients Undergoing Small Bowel Resection for Complicated Crohn's Disease: A Multicentre Case-Control Study.

Crohn's disease (CD) is associated with an increased risk of small bowel neoplasia (SBN). We aimed to assess preoperative predictors of SBN in CD patients. We conducted a retrospective case-control study including CD patients who underwent surgery: cases were diagnosed with SBN on histopathological analysis and controls had no neoplasia. Preoperative cross-sectional imaging was reviewed by a panel of blinded expert radiologists. Fifty cases were matched to one hundred and fifty consecutive controls. In multivariable analysis, predictors of SBN were age ≥ 50 years (OR = 28, 95% CI = 5.05-206), median CD duration ≥ 17.5 years (OR = 4.25, 95% CI = 1.33-14.3), and surgery for stricture (OR = 5.84, 95% CI = 1.27-35.4). The predictors of small bowel adenocarcinoma were age ≥ 50 years (OR = 5.14, 95% CI = 2.12-12.7), CD duration ≥ 15 years (OR = 5.65, 95% CI = 2.33-14.3), and digestive wall thickening > 8 mm (OR = 3.79, 95% CI = 1.45-11.3). A predictive score based on the aforementioned factors was constructed. Almost 73.7% of patients with a high score had SBA. Old age, long small bowel CD duration, and stricture predicted the presence of SBN, particularly adenocarcinoma when patients have digestive wall thickening > 8 mm on preoperative imaging.

Amylo-AFFECT-QOL, a self-reported questionnaire to assess health-related quality of life and to determine the prognosis in cardiac amyloidosis.

Background and aims: Self-reported questionnaires are useful for estimating the health-related quality of life (HR-QoL), impact of interventions, and prognosis. To our knowledge, no HR-QoL questionnaire has been developed for cardiac amyloidosis (CA). This study aimed to validate Amylo-AFFECT-QOL questionnaire to assess HR-QoL and its prognostic value in CA. Methods: A self-reported questionnaire, "Amylo-AFFECT" had been designed and validated for CA symptoms evaluation and screening by physicians. It was adapted here to assess HR-QoL (Amylo-AFFECT-QOL) and its prognostic value in CA. To validate the theoretical model, internal consistency and convergent validity were assessed, particularly correlations between Amylo-AFFECT-QOL and the HR-QoL Minnesota Living Heart Failure (MLHF) questionnaire. Results: Amylo-AFFECT-QOL was completed by 515 patients, 425 of whom (82.5%) had CA. Wild-type and hereditary transthyretin amyloidosis (ATTRwt and ATTRv) and immunoglobulin light-chain amyloidosis (AL) were diagnosed in 47.8, 14.7, and 18.8% of cases, respectively. The best HR-QoL evaluation was obtained with five dimensions: "Heart failure," "Vascular dysautonomia," "Neuropathy," "Ear, gastrointestinal, and urinary dysautonomia," and "Skin or mucosal involvement." The global Amylo-AFFECT-QOL and MLHF scores showed significant positive correlations (rs = 0.72, p < 0.05). Patients with a final diagnosis of CA had a global Amylo-AFFECT-QOL score significantly higher than the control group composed by patients with other diagnoses (22.2 ± 13.6 vs. 16.2 ± 13.8, respectively, p-value < 0.01). According to the Amylo-AFFECT-QOL global results, ATTRv patients' QoL was more affected than AL patients' QoL or ATTRwt patients' QoL. Patients with a higher HR-QoL score had a greater risk of death or heart transplant after 1 year of follow-up (log-rank < 0.01). Conclusion: Amylo-AFFECT-QOL demonstrates good psychometric properties and is useful for quantifying HR-QoL and estimating CA prognosis. Its use may help to improve overall management of patients with CA.

Adalimumab in Biologic-naïve Patients With Crohn's Disease After Resolution of an Intra-abdominal Abscess: A Prospective Study From the GETAID.

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. CLINICALTRIALS: gov, Number: NCT02856763.

Risk of SARS-CoV-2 infection in healthcare workers with inflammatory bowel disease: a case-control study.

Background: Whether healthcare workers with inflammatory bowel disease (IBD) are at increased risk of Novel coronavirus disease (COVID-19) due to occupational exposure is unknown. Aim: To assess the risk of COVID-19 in healthcare workers with IBD. Methods: A case control study enrolled 326 healthcare workers with IBD from 17 GETAID centres and matched non-healthcare workers with IBD controls (1:1) for gender, age, disease subtype and year of diagnosis. The study period was year 2020 during the COVID-19 outbreak. Results: In total, 59 COVID-19 were recorded among cases (n = 32) and controls (n = 27), including 2 severe COVID-19 (requiring hospitalization, mechanic ventilation) but no death. No difference was observed between healthcare workers and controls regarding the overall incidence rates of COVID-19 4.9 ± 2.2 vs. 3.8 ± 1.9 per 100 patient-semesters, P = 0.34) and the overall incidence rates of severe COVID-19 (0.6 ± 7.8 vs. 0.3 ± 5.5 per 100 patient-semesters, P = 0.42). In multivariate analysis in the entire study population, COVID-19 was associated with patients with body mass index > 30 kg/m2 (HR = 2.48, 95%CI [1.13-5.44], P = 0.02). Conclusion: Healthcare workers with IBD do not have an increased risk of COVID-19 compared with other patients with IBD.

Comparative Acceptability of Therapeutic Maintenance Regimens in Patients With Inflammatory Bowel Disease: Results From the Nationwide ACCEPT2 Study.

BACKGROUND: Owing to growing number of therapeutic options with similar efficacy and safety, we compared the acceptability of therapeutic maintenance regimens in inflammatory bowel disease (IBD). METHODS: From a nationwide study (24 public or private centers), IBD patients were consecutively included for 6 weeks. A dedicated questionnaire including acceptability numerical scales (ANS) ranging from 0 to 10 (highest acceptability) was administered to both patients and related physicians. RESULTS: Among 1850 included patients (65.9% with Crohn's disease), the ANS were 8.68 ± 2.52 for oral route (first choice in 65.8%), 7.67 ± 2.94 for subcutaneous injections (first choice in 21.4%), and 6.79 ± 3.31 for intravenous infusions (first choice in 12.8%; P < .001 for each comparison). In biologic-naïve patients (n = 315), the most accepted maintenance regimens were oral intake once (ANS = 8.8 ± 2.2) or twice (ANS = 6.9 ± 3.4) daily and subcutaneous injections every 12 or 8 weeks (ANS = 7.9 ± 3.0 and ANS = 7.2 ± 3.2, respectively). Among 342 patients with prior exposure to subcutaneous biologics, the preferred regimens were subcutaneous injections (≥2 week-intervals; ANS between 9.1 ± 2.3 and 8.1 ± 2.7) and oral intake once daily (ANS = 7.7 ± 3.2); although it was subcutaneous injections every 12 or 8 weeks (ANS = 8.4 ± 3.0 and ANS = 8.1 ± 3.0, respectively) and oral intake once daily (ANS = 7.6 ± 3.1) in case of prior exposure to intravenous biologics (n = 1181). The impact of usual therapeutic escalation or de-escalation was mild (effect size <0.5). From patients' acceptability perspective, superiority and noninferiority cutoff values should be 15% and 5%, respectively. CONCLUSIONS: Although oral intake is overall preferred, acceptability is highly impacted by the rhythm of administration and prior medication exposures. However, SC treatment with long intervals between 2 injections (≥8 weeks) and oral intake once daily seems to be the most accepted modalities.

Considering both the route of medication delivery and the interval between 2 administrations, we observed a strong impact of patients' experience regarding previous treatments. The most accepted maintenance regimens were subcutaneous injections with interval ≥8 weeks and oral intake.

Real-world comparison of effectiveness between tofacitinib and vedolizumab in patients with ulcerative colitis exposed to at least one anti-TNF agent.

BACKGROUND: Data comparing tofacitinib and vedolizumab in ulcerative colitis (UC) are lacking. AIMS: To compare the effectiveness of tofacitinib and vedolizumab in patients with UC who had prior exposure to anti-TNF therapy METHODS: In this multicentre study, we included consecutive patients with UC ≥18 years old with partial Mayo score >2 and prior anti-TNF exposure, who started tofacitinib or vedolizumab between January 2019 and June 2021. Comparisons were performed using propensity score analyses (inverse probability of treatment weighting). RESULTS: Overall, 126 and 178 patients received tofacitinib and vedolizumab, respectively. Intensified induction (vedolizumab infusion at week 10 or tofacitinib 10 mg b.d until week 16) was performed in 28.5% and 41.5% of patients, respectively. After propensity-score analysis, corticosteroid-free clinical remission (partial Mayo score ≤2) was achieved at week 16 in 45.1% and 40.2% of patients receiving tofacitinib and vedolizumab, respectively (aOR = 0.82 [0.35-1.91], p = 0.64). Endoscopic improvement (corticosteroid-free clinical remission and endoscopic Mayo score ≤1) (aOR = 0.23[0.08-0.65], p = 0.0032) and histological healing (endoscopic improvement + Nancy histological index ≤1) (13.4% vs 3.2%, aOR = 0.21[0.05-0.91], p = 0.023) were higher at week 16 in patients treated with tofacitinib. No factor was predictive of tofacitinib effectiveness. At least one primary failure to a biologic (OR = 0.46[0.22-0.99], p = 0.049), partial Mayo score >6 (OR = 0.39[0.17-0.90], p = 0.029) and CRP level > 30 mg/L at baseline (OR = 0.08[0.01-0.85], p = 0.036) were associated with vedolizumab failure. CONCLUSION: Tofacitinib and vedolizumab are effective in UC after failure of anti-TNF agents. However, tofacitinib seems more effective, especially in severe disease and primary failure to biologics.

Severe colitis in patients with melanoma treated with BRAF/MEK inhibitors.

BACKGROUND AND AIMS: Dual blockade of BRAF and MEK kinases is a standard of care for metastatic V600E/K BRAF mutant melanoma. This study reports the first systematic description of colitis due to BRAF and MEK inhibitors. METHODS: We studied consecutive patients with melanoma, treated with BRAF and MEK inhibitors, who had colitis requiring hospitalisation. Electronic files were studied; endoscopic biopsies and colectomy specimens were read centrally. RESULTS: Between January 2021 and March 2022, nine women and one man, aged 50-90 years, were studied. Nine patients received encorafenib and binimetinib; one patient received dabrafenib and trametinib. The main symptoms were diarrhoea, haematochezia, abdominal pain and intestinal obstruction. Blood tests showed anaemia, increased CRP and low serum albumin levels in most patients. All patients had ulcerations of the right colon with (2/10) or without (8/10) stenosis of the ileocecal valve, and 4/10 patients also had ulcerations distal to the right colon. Histopathological findings were suggestive of ischaemia and mild inflammation. Nine of the 10 patients discontinued BRAF/MEK inhibitors. Drugs were reintroduced in four patients, three of whom had a severe relapse of diarrhoea. Two patients required surgery and underwent intestinal resection. One patient died of enterocolitis. CONCLUSION: BRAF/MEK inhibitors can induce severe colitis characterised by ulcerations of the right colon.

Biologic Therapy for Budesonide-refractory, -dependent or -intolerant Microscopic Colitis: a Multicentre Cohort Study from the GETAID.

BACKGROUND: Budesonide remains the backbone therapy for microscopic colitis [MC]; however, relapses are frequent, and some patients are intolerant or dependent. Anti-TNF therapy is increasingly used to treat these patients, but available evidence is still limited. The aim of this study was to evaluate the effectiveness and safety of anti-TNF therapy in MC patients failing budesonide. METHODS: In a multicentre retrospective cohort study, budesonide-refractory, -dependent, or -intolerant MC patients treated with anti-TNF agents were included. Clinical remission was defined as fewer than three bowel movements per day, and clinical response was defined as an improvement in stool frequency of at least 50%. RESULTS: Fourteen patients were included. Median age was 58.5 years, median disease duration was 25 months, and median follow-up was 29.5 months. Seven patients were treated with infliximab [IFX], and seven with adalimumab. Clinical remission without steroids at 12 weeks was reached in 5/14 [35.7%] patients; all of these received IFX. Clinical response at 12 and 52 weeks, was obtained in 9/14 [64.3%] and 7/14 [50%] patients, respectively. Five patients switched to another anti-TNF agent. When considering both first- and second-line anti-TNF therapies, 7 [50%] patients were in clinical remission at Week 52. Mild to moderate adverse events were reported in six ptients. Two patients were treated with vedolizumab, of whom one had clinical response; one patient treated with ustekinumab had no response. CONCLUSIONS: This is the first multicentre cohort study showing that half of patients treated with anti-TNF therapy for MC achieved clinical remission in case of budesonide failure.

Comparative real-world effectiveness of vedolizumab and ustekinumab for patients with ulcerative colitis: a GETAID multicentre cohort study.

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.
