ABSTRACT
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.

BACKGROUND: The systematic use of susceptibility testing and tailored first-line treatment for Helicobacter pylori eradication has yet to be established. AIM: To compare 14-day tailored PCR-guided triple therapy to 14-day non-Bismuth concomitant quadruple therapy for first-line Helicobacter pylori eradication. PATIENTS AND METHODS: We performed a multicenter, parallel-group, randomized noninferiority controlled trial. Naive adult patients with Helicobacter pylori infection were treated with 14-day tailored PCR-guided triple therapy (esomeprazole 40 mg and amoxicillin 1000 mg b.d. plus clarithromycin 500 mg or levofloxacin 500 mg b.d. according to clarithromycin susceptibility) or 14-day non-Bismuth concomitant quadruple therapy (esomeprazole 40 mg, amoxicillin 1000 mg, clarithromycin 500 mg, and metronidazole 500 mg b.d.). The primary endpoint was H. pylori eradication. RESULTS: We screened 991 patients for eligibility and randomized 241 patients. The first-line eradication rate was 99.2% in the tailored PCR-guided group and 95.9% in the control group (ITT population; absolute difference of +3.30%, with a lower bound of CI at -0.68%). Both first-line therapies were well tolerated, with a formally significant difference in favor of the tailored PCR-guided group (61.4% vs. 41.2%, p = 0.003). Economic analyses revealed a lower cost of the tailored PCR-guided arm, with a 92% chance of being jointly more effective and less expensive than the control arm in the ITT population. CONCLUSION: In a country with a high level of clarithromycin resistance, the results of our study demonstrated the noninferiority of 14-day tailored PCR-guided triple therapy as a first-line H. pylori eradication therapy compared to 14-day non-Bismuth quadruple therapy (ClinicalTrials.gov NCT02576236).

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 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.

BACKGROUND & AIMS: Tools for stratification of relapse risk of Crohn's disease (CD) after anti-tumor necrosis factor (TNF) therapy cessation are needed. We aimed to validate a previously developed prediction model from the diSconTinuation in CrOhn's disease patients in stable Remission on combined therapy with Immunosuppressants (STORI) trial, and to develop an updated model. METHODS: Cohort studies were selected that reported on anti-TNF cessation in 30 or more CD patients in remission. Individual participant data were requested for luminal CD patients and anti-TNF treatment duration of 6 months or longer. The discriminative ability (concordance-statistic [C-statistic]) and calibration (agreement between observed and predicted risks) were explored for the STORI model. Next, an updated prognostic model was constructed, with performance assessment by cross-validation. RESULTS: This individual participant data meta-analysis included 1317 patients from 14 studies in 11 countries. Relapses after anti-TNF cessation occurred in 632 of 1317 patients after a median of 13 months. The pooled 1-year relapse rate was 38%. The STORI prediction model showed poor discriminative ability (C-statistic, 0.51). The updated model reached a moderate discriminative ability (C-statistic, 0.59), and included clinical symptoms at cessation (hazard ratio [HR], 2.2; 95% CI, 1.2-4), younger age at diagnosis (HR, 1.5 for A1 (age at diagnosis ≤16 years) vs A2 (age at diagnosis 17 - 40 years); 95% CI, 1.11-1.89), no concomitant immunosuppressants (HR, 1.4; 95% CI, 1.18-172), smoking (HR, 1.4; 95% CI, 1.15-1.67), second line anti-TNF (HR, 1.3; 95% CI, 1.01-1.69), upper gastrointestinal tract involvement (HR, 1.3 for L4 vs non-L4; 95% CI, 0.96-1.79), adalimumab (HR, 1.22 vs infliximab; 95% CI, 0.99-1.50), age at cessation (HR, 1.2 per 10 years younger; 95% CI, 1-1.33), C-reactive protein (HR, 1.04 per doubling; 95% CI, 1.00-1.08), and longer disease duration (HR, 1.07 per 5 years; 95% CI, 0.98-1.17). In subanalysis, the discriminative ability of the model improved by adding fecal calprotectin (C-statistic, 0.63). CONCLUSIONS: This updated prediction model showed a reasonable discriminative ability, exceeding the performance of a previously published model. It might be useful to guide clinical decisions on anti-TNF therapy cessation in CD patients after further validation.

BACKGROUND: Paradoxical reactions (PRs) are defined as the occurrence during biologic therapy of a pathological condition that usually responds to these drugs. OBJECTIVES: To estimate the incidence of PRs and identify risk factors. METHODS: Multicentre study of the database for the Greater Paris University Hospitals, including biologic-naive patients receiving anti-tumour necrosis factor-α, anti-interleukin-12/23, anti-interleukin-17 or anti-α4ß7-integrin agents for psoriasis, inflammatory rheumatism or inflammatory bowel disease (IBD). We used natural language processing algorithms to extract data. A cohort and a case-control study nested in the cohort with controls selected by incidence density sampling was used to identify risk factors. RESULTS: Most of the 9303 included patients (median age 43·0, 53·8% women) presented an IBD (3773, 40·6%) or a chronic inflammatory rheumatic disease (3708, 39·9%), and 8489 (91·3%) received anti-TNF-α agents. A total of 297 (3·2%) had a PR. The global incidence rate was 7·6 per 1000 person-years [95% confidence interval (CI) 6·8-8·5]. The likelihood of PR was associated with IBD [adjusted odds ratio (aOR) 1·9, 95% CI 1·1-3·2, P = 0·021] and a combination of at least two inflammatory diseases (aOR 6·1, 95% CI 3·6-10·6, P < 0·001) and was reduced with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and corticosteroids (aOR 0·6, 95% CI 0·4-0·8, P = 0·002; and OR 0·4, 95% CI 0·2-0·6, P = 0·002, respectively). CONCLUSIONS: The likelihood of PRs was associated with IBD or a combination of a least two inflammatory diseases. More studies are needed to assess the benefit of systematically adding csDMARDs for such high-risk patients. What is already known about this topic? Most published studies about paradoxical reactions concern paradoxical psoriasis in patients receiving anti-tumour necrosis factor-α agents. Few data are available for other paradoxical reactions and the most recent biologics. What does this study add? Risk of paradoxical reactions was increased with inflammatory bowel disease and a combination of at least two inflammatory diseases. Risk of paradoxical reactions was reduced with conventional synthetic disease-modifying antirheumatic drugs or corticosteroid therapy, which could be added for high-risk patients.

BACKGROUND: Little is known about clinical characteristics and kidney outcomes in patients with biopsy-proven immunoglobulin A nephropathy (IgAN) in a context of inflammatory bowel disease (IBD). METHODS: We conducted a retrospective multicentre study with a centralized histological review to analyse the presentation, therapeutic management and outcome of 24 patients suffering from IBD-associated IgAN relative to a cohort of 134 patients with primary IgAN without IBD. RESULTS: Crohn's disease and ulcerative colitis accounted for 75 and 25% of IBD-associated IgAN cases, respectively. IBD was diagnosed before IgAN in 23 cases (a mean of 9 years previously) and was considered active at IgAN onset in 23.6% of patients. Hypertension was present in 41.7% of patients. The urinary protein:creatinine ratio exceeded 100 mg/mmol in 70.8% of patients (mean 254 mg/mmol). Estimated glomerular filtration rate (eGFR) was >60 mL/min/1.73 m2 in 13/24 patients and only 1 patient required dialysis. In the Oxford mesangial hypercellularity, endocapillary cellularity, segmental sclerosis and interstitial fibrosis/tubular atrophy with crescents classification of renal biopsies, 57% were M1, 48% E1, 76% S1, 57% T1-2 and 38% C1-2. Steroids were administered in 50% of cases. After a mean follow-up of 7.2 years, 4 patients (16.7%) had a poor kidney outcome: end-stage renal disease (n = 3) or a >50% decrease in eGFR from initial values (n = 1). A similar evolution was observed in patients with primitive IgAN. CONCLUSIONS: This first case series suggests that IBD-associated IgAN has frequent inflammatory lesions at onset and variable long-term outcomes.

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.

Sporadic colorectal cancer (CRC) is a result of complex interactions between the host and its environment. Environmental stressors act by causing host cell DNA alterations implicated in the onset of cancer. Here we investigate the stressor ability of CRC-associated gut dysbiosis as causal agent of host DNA alterations. The epigenetic nature of these alterations was investigated in humans and in mice. Germ-free mice receiving fecal samples from subjects with normal colonoscopy or from CRC patients were monitored for 7 or 14 wk. Aberrant crypt foci, luminal microbiota, and DNA alterations (colonic exome sequencing and methylation patterns) were monitored following human feces transfer. CRC-associated microbiota induced higher numbers of hypermethylated genes in murine colonic mucosa (vs. healthy controls' microbiota recipients). Several gene promoters including SFRP1,2,3, PENK, NPY, ALX4, SEPT9, and WIF1 promoters were found hypermethylated in CRC but not in normal tissues or effluents from fecal donors. In a pilot study (n = 266), the blood methylation levels of 3 genes (Wif1, PENK, and NPY) were shown closely associated with CRC dysbiosis. In a validation study (n = 1,000), the cumulative methylation index (CMI) of these genes was significantly higher in CRCs than in controls. Further, CMI appeared as an independent risk factor for CRC diagnosis as shown by multivariate analysis that included fecal immunochemical blood test. Consequently, fecal bacterial species in individuals with higher CMI in blood were identified by whole metagenomic analysis. Thus, CRC-related dysbiosis induces methylation of host genes, and corresponding CMIs together with associated bacteria are potential biomarkers for CRC.

BACKGROUND & AIMS: There is consensus on the criteria used to define acute severe ulcerative colitis (ASUC) and on patient management, but it has been a challenge to identify patients at risk for colectomy based on data collected at hospital admission. We aimed to develop a system to determine patients' risk of colectomy within 1 y of hospital admission for ASUC based on clinical, biomarker, and endoscopy data. METHODS: We performed a retrospective analysis of consecutive patients with ASUC treated with corticosteroids, ciclosporin, or tumor necrosis factor (TNF) antagonists and admitted to 2 hospitals in France from 2002 through 2017. Patients were followed until colectomy or loss of follow up. A total of 270 patients with ASUC were included in the final analysis, with a median follow-up time of 30 months (derivation cohort). Independent risk factors identified by Cox multivariate analysis were used to develop a system to identify patients at risk for colectomy 1 y after ASUC. We developed a scoring system based on these 4 factors (1 point for each item) to identify high-risk (score 3 or 4) vs low-risk (score 0) patients. We validated this system using data from an independent cohort of 185 patients with ASUC treated from 2006 through 2017 at 2 centers in France. RESULTS: In the derivation cohort, the cumulative risk of colectomy was 12.3% (95% CI, 8.6-16.8). Based on multivariate analysis, previous treatment with TNF antagonists or thiopurines (hazard ratio [HR], 3.86; 95% CI, 1.82-8.18), Clostridioides difficile infection (HR, 3.73; 95% CI, 1.11-12.55), serum level of C-reactive protein above 30 mg/L (HR, 3.06; 95% CI, 1.11-8.43), and serum level of albumin below 30 g/L (HR, 2.67; 95% CI, 1.20-5.92) were associated with increased risk of colectomy. In the derivation cohort, the cumulative risks of colectomy within 1 y in patients with scores of 0, 1, 2, 3, or 4 were 0.0%, 9.4% (95% CI, 4.3%-16.7%), 10.6% (95% CI, 5.6%-17.4%), 51.2% (95% CI, 26.6%-71.3%), and 100%. Negative predictive values ranged from 87% (95% CI, 82%-91%) to 92% (95% CI, 88%-95.0%). Findings from the validation cohort were consistent with findings from the derivation cohort. CONCLUSIONS: We developed a scoring system to identify patients at low-risk vs high-risk for colectomy within 1 y of hospitalization for ASUC, based on previous treatment with TNF antagonists or thiopurines, C difficile infection, and serum levels of CRP and albumin. The system was validated in an external cohort.

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.

BACKGROUND & AIMS: Few data are available on the effects of tumor necrosis factor (TNF) antagonist therapy for patients with internal fistulizing Crohn's disease (CD) and there is debate regarding the risk of abscess. We aimed to assess the long-term efficacy and safety of anti-TNF therapy for patients with internal fistulas. METHODS: We performed a retrospective study of data collected from the Groupe d'Etude Thérapeutique des Affections Inflammatoires Digestives trial, from January 1, 2000, through December 31, 2017. Our final analysis included 156 patients who began treatment with an anti-TNF agent for CD with internal fistula (83 men; median disease duration, 4.9 y). The primary end point was the onset of a major abdominal surgery. Secondary analysis included disappearance of the fistula tract during follow-up evaluation and safety. The Kaplan-Meier method was used for statistical analysis. RESULTS: After a median follow-up period of 3.5 years, 68 patients (43.6%) underwent a major abdominal surgery. The cumulative probabilities for being surgery-free were 83%, 64%, and 51% at 1, 3, and 5 years, respectively. A concentration of C-reactive protein >18 mg/L, an albumin concentration <36 g/L, the presence of an abscess at the fistula diagnosis, and the presence of a stricture were associated independently with the need for surgery. The cumulative probabilities of fistula healing, based on imaging analyses, were 15.4%, 32.3%, and 43.9% at 1, 3, and 5 years, respectively. Thirty-two patients (20.5%) developed an intestinal abscess and 4 patients died from malignancies (3 intestinal adenocarcinomas). One patient died from septic shock 3 months after initiation of anti-TNF therapy. CONCLUSIONS: In a retrospective analysis of data from a large clinical trial, we found that anti-TNF therapy delays or prevents surgery for almost half of patients with CD and luminal fistulas. However, anti-TNF therapy might increase the risk for sepsis-related death or gastrointestinal malignancies.

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.

INTRODUCTION: New therapeutic options for patients with Crohn's disease (CD) with perianal lesions failing anti-tumor necrosis factor (TNF) agents are needed. We aimed to assess the effectiveness of ustekinumab in perianal CD (pCD) and predictors of clinical success in a real-life multicenter cohort. METHODS: We conducted a national multicenter retrospective cohort study in patients with either active or inactive pCD who received ustekinumab. In patients with active pCD at treatment initiation, the success of ustekinumab was defined by clinical success at 6 months assessed by the physician's judgment without additional medical or surgical treatment for pCD. Univariate and multivariable logistic regression analyses were performed to identify predictors of success. In patients with inactive pCD at ustekinumab initiation, the pCD recurrence-free survival was calculated using the Kaplan-Meier method. RESULTS: Two hundred seven patients were included, the mean age was 37.7 years, the mean duration of CD was 14.3 years, and the mean number of prior perianal surgeries was 2.8. Two hundred five (99%) patients had previously been exposed to at least 1 anti-TNF and 58 (28%) to vedolizumab. The median follow-up time was 48 weeks; 56/207 (27%) patients discontinued therapy after a median time of 43 weeks. In patients with active pCD, success was reached in 57/148 (38.5%) patients. Among patients with setons at initiation, 29/88 (33%) had a successful removal. The absence of optimization was associated with treatment success (P = 0.044, odds ratio 2.74; 95% confidence interval: 0.96-7.82). In multivariable analysis, the number of prior anti-TNF agents (≥3) was borderline significant (P = 0.056, odds ratio 0.4; 95% confidence interval: 0.15-1.08). In patients with inactive pCD at initiation, the probability of recurrence-free survival was 86.2% and 75.1% at weeks 26 and 52, respectively. DISCUSSION: Ustekinumab appears as a potential effective therapeutic option in perianal refractory CD. Further prospective studies are warranted.

BACKGROUND: The role of robotic surgery for partial mesorectal excision (PME) in patients with high rectal cancer (RC) remains unexplored. This study aimed to compare the operative and postoperative outcomes of robotic (R-PME) versus laparoscopic (L-PME) PME for high RC. METHODS: This was a single-center propensity score cohort study of consecutive patients diagnosed with RC in the high rectum (>10 to 15 cm from the anal verge) who underwent surgery between September 2012 and May 2019. RESULTS: Of 131 selected patients (50 R-PME and 81 L-PME), 88 were matched using propensity score (44 per group). Operative and postoperative variables were similar between R-PME and L-PME patients, except for operative time (220 min and 190 min, respectively; p < 0.0001). No conversion was needed. Overall morbidity was 15.9%; 4 patients (4.5%) developed anastomotic leakage. The mean hospital stay was 7.25 days for R-PME vs. 7.64 days for L-PME (p = 0.597). R0 resection was achieved in 100% of R-PME and 90.9% of L-PME (p = 0.116). Only 3 patients (1 R-PME, 2 L-PME) received a permanent stoma (p = 1). No group differences were observed for overall or disease-free survival rates at 5 years. The costs of R-PME were significantly higher than those of L-PME. CONCLUSION: Minimally invasive surgery can be performed safely for PME in high RC. No difference can be detected between R-PME and L-PME for both short- and long-term outcomes, leaving the choice of the surgical approach to the surgeon's experience. Specific health economic studies are needed to evaluate the cost-effectiveness of robotic surgery for RC.

Antimicrobial peptides (AMP) are defense effectors of the innate immunity playing a crucial role in the intestinal homeostasis with commensals and protection against pathogens. Herein we aimed to investigate AMP gene regulation by deciphering specific characteristics allowing their enhanced expression among innate immune genes, particularly those encoding proinflammatory mediators. Our emphasis was on epigenetic regulation of the gene encoding the AMP ß-defensin 2 (HBD2), taken as a model of possibly specific induction, upon challenge with a commensal bacterium, compared with the proinflammatory cytokine IL-8. Using an in vitro model of colonic epithelial cells challenged with Escherichia coli K12, we showed that inhibition of histone deacetylases (HDAC) by trichostatin A dramatically enhanced induction of HBD2 expression, without affecting expression of IL-8. This mechanism was supported by an increased phosphorylation of histone H3 on serine S10, preferentially at the HBD2 promoter. This process occurred through activation of the IκB kinase complex, which also led to activation of NF-κB. Moreover, we demonstrated that NF-κB was modified by acetylation upon HDAC inhibition, partly by the histone acetyltransferase p300, and that both NF-κB and p300 supported enhanced induction of HBD2 expression. Furthermore, we identified additional genes belonging to antimicrobial defense and epithelial restitution pathways that showed a similar pattern of epigenetic control. Finally, we confirmed our finding in human colonic primary cells using an ex vivo organoid model. This work opens the way to use epigenetic pharmacology to achieve induction of epithelial antimicrobial defenses, while limiting the deleterious risk of an inflammatory response.

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: Few people know of autoimmune pancreatitis (AIP), a rare disorder associated with inflammatory bowel diseases (IBD). We aimed to describe phenotype and outcomes of IBD and AIP when associated. METHODS: We performed a retrospective study of cases of AIP in IBD identified from the multicenter Groupe d'Etude Thérapeutique des Affections Inflammatoires du tube Digestif in Belgium and France from July 2012 through July 2015. Patients were diagnosed with AIP based on the International Consensus Diagnostic Criteria for AIP. A definitive AIP diagnosis was based on histological analysis of pancreatic resection specimens or samples collected by fine-needle aspiration during endoscopic ultrasound. Patients with probable type 1 AIP were identified based on imaging findings, clinical and/or radiologic responses to steroids, level of serum immunoglobulin G4, and involvement of other organs. Patients with probable type 2 AIP were identified based on imaging findings, clinical and/or radiologic responses to steroids, and association with IBD. The primary objective was to collect information on the characteristics of AIP in patients with IBD. We also compared features of patients with IBD with and without AIP in a case-control analysis, using multivariate analysis. RESULTS: We analyzed data from 91 individuals with AIP and IBD (47 women) seen at 23 centers (58 had ulcerative colitis [UC] and 33 Crohn's disease [CD]). Eighty-nine patients had type 2 AIP, and 2 patients had type 1 AIP. The mean age at diagnosis of AIP was 35 ± 12 years, and for IBD it was 32 ± 12 years. AIP preceded IBD in 19 patients (21%). Over a mean follow-up period of 5.7 ± 4.9 years, 31 patients (34%) relapsed, 11 patients (12%) developed diabetes, and 17 patients (19%) developed exocrine pancreatic insufficiency. In patients with UC, factors independently associated with AIP included proctitis (odds ratio [OR], 2.9; 95% confidence interval [CI], 1.3-6.3; P = .007) and colectomy (OR, 7.1; 95% CI, 2.5-20; P = .0003). In patients with CD, AIP was significantly associated with fewer perianal lesions (OR, 0.16; 95% CI, 0.03-0.77; P = .023), non-stricturing non-penetrating CD (OR, 6.7; 95% CI, 1.25-33.3; P = .0029), and higher rate of colectomy (OR, 27.8; 95% CI, 3.6-217; P = .0029). CONCLUSIONS: In a multicenter retrospective analysis of patients with AIP and IBD, followed for an average of 5.7 ± 4.9 years, we found most to have type 2 AIP. Two-thirds of patients have UC, often with proctitis. One-third of patients have CD, often with inflammatory features. Patients with IBD and AIP have higher rates of colectomy than patients with just IBD.

OBJECTIVES: To determine the cumulative incidence and the prognostic factors of ileorectal anastomosis (IRA) failure after colectomy for ulcerative colitis (UC). BACKGROUND: Although ileal pouch-anal anastomosis is recommended after colectomy for UC, IRA is still performed. METHODS: This was a multicenter retrospective cohort study, which included patients with IRA for UC performed between 1960 and 2014. IRA failure was defined as secondary proctectomy and/or rectal cancer occurrence. Uni- and multivariate survival analyses were performed using Cox-proportional hazards models. RESULTS: A total of 343 patients from 13 French centers were included. Median follow up after IRA was 10.6 years. IRA failure rates were estimated at 27.0% (95% confidence interval, CI, 22-32) and 40.0% (95% CI 33-47) at 10 and 20 years, respectively. Median survival time without IRA failure was estimated at 26.8 years. Two thirds of secondary proctectomies were performed for refractory proctitis, and 20% for rectal neoplasia. Univariate analysis identified factors associated with IRA failure: IRA performed after 2005, a longer duration of disease at the time of IRA, indication for colectomy and having received immunomodulative agents before IRA. In multivariate analysis, treatment with both immunosuppressant (IS) and anti-TNF before colectomy was independently associated with IRA failure (HR=2.9, 95% CI 1.2-7.1). Conversely, colectomy for severe acute colitis was associated with decreased risk of IRA failure (HR=0.6, 95% CI 0.4-0.97). DISCUSSION: Patients with UC have a high risk of IRA failure, particularly when colectomy is performed for refractory disease. However, IRA could be discussed after colectomy for severe acute colitis, or in patients naive to IS and anti-TNF.
