RESUMEN
BACKGROUND & AIMS: Patients with inflammatory bowel disease (IBD) frequently develop extraintestinal manifestations (EIMs) that contribute substantially to morbidity. We assembled the largest multicohort data set to date to investigate the clinical, serologic, and genetic factors associated with EIM complications in IBD. METHODS: Data were available in 12,083 unrelated European ancestry IBD cases with presence or absence of EIMs (eg, ankylosing spondylitis [ankylosing spondylitis and sacroiliitis], primary sclerosing cholangitis [PSC], peripheral arthritis, and skin and ocular manifestations) across 4 cohorts (Cedars-Sinai Medical Center, National Institute for Diabetes and Digestive and Kidney Diseases IBD Genetics Consortium, Sinai Helmsley Alliance for Research Excellence Consortium, and Risk Stratification and Identification of Immunogenetic and Microbial Markers of Rapid Disease Progression in Children with Crohn's Disease cohort). Clinical and serologic parameters were analyzed by means of univariable and multivariable regression analyses using a mixed-effects model. Within-case logistic regression was performed to assess genetic associations. RESULTS: Most EIMs occurred more commonly in female subjects (overall EIM: P = 9.0E-05, odds ratio [OR], 1.2; 95% CI, 1.1-1.4), with CD (especially colonic disease location; P = 9.8E-09, OR, 1.7; 95% CI, 1.4-2.0), and in subjects who required surgery (both CD and UC; P = 3.6E-19, OR, 1.7; 95% CI, 1.5-1.9). Smoking increased risk of EIMs except for PSC, where there was a "protective" effect. Multiple serologic associations were observed, including with PSC (anti-nuclear cytoplasmic antibody; IgG and IgA, anti-Saccharomyces cerevisiae antibodies; and anti-flagellin) and any EIM (anti-nuclear cytoplasmic antibody; IgG and IgA, anti-Saccharomyces cerevisiae antibodies; and anti-Pseudomonas fluorescens-associated sequence). We identified genome-wide significant associations within major histocompatibility complex (ankylosing spondylitis and sacroiliitis, P = 1.4E-15; OR, 2.5; 95% CI, 2.0-3.1; PSC, P = 2.7E-10; OR, 2.8; 95% CI, 2.0-3.8; ocular, P = 2E-08, OR, 3.6; 95% CI, 2.3-5.6; and overall EIM, P = 8.4E-09; OR, 2.2; 95% CI, 1.7-2.9) and CPEB4 (skin, P = 2.7E-08; OR, 1.5; 95% CI, 1.3-1.8). Genetic associations implicated tumor necrosis factor, JAK-STAT, and IL6 as potential targets for EIMs. Contrary to previous reports, only 2% of our subjects had multiple EIMs and most co-occurrences were negatively correlated. CONCLUSIONS: We have identified demographic, clinical, and genetic associations with EIMs that revealed underlying mechanisms and implicated novel and existing drug targets-important steps toward a more personalized approach to IBD management.

The therapeutic armamentarium for management of inflammatory bowel diseases (IBD) has expanded dramatically in the last 5 years, with the introduction of several medications with different mechanisms of action. These include the oral small molecule drugs Janus kinase inhibitors (JAKi, including upadacitinib approved for Crohn's disease [CD] and ulcerative colitis [UC], as well as tofacitinib, approved for UC) and sphingosphine 1-phosphate receptor (S1PR) modulators (ozanimod and etrasimod, both approved for UC), as well as biologic agents like selective interleukin-23 (IL23) antagonists (risankizumab approved for CD, and mirikizumab approved for UC). The efficacy and safety of these therapies vary. In this review, we discuss practical use of these newer advanced therapies focusing on real-world effectiveness and safety data, dosing and monitoring considerations, as well as special situations for their use such as pregnancy, co-morbid immune-mediated disease, use in hospitalized patients with acute severe UC, and in the perioperative setting. We also propose our approach to positioning these therapies in clinical practice, relying on careful integration of the medication's comparative effectiveness and safety in the context of an individual patient's risk of disease- and treatment-related complications and preferences.
RESUMEN
OBJECTIVE: Perianal Crohn's disease (pCD) occurs in up to 40% of patients with CD and is associated with poor quality of life, limited treatment responses and poorly understood aetiology. We performed a genetic association study comparing CD subjects with and without perianal disease and subsequently performed functional follow-up studies for a pCD associated SNP in Complement Factor B (CFB). DESIGN: Immunochip-based meta-analysis on 4056 pCD and 11 088 patients with CD from three independent cohorts was performed. Serological and clinical variables were analysed by regression analyses. Risk allele of rs4151651 was introduced into human CFB plasmid by site-directed mutagenesis. Binding of recombinant G252 or S252 CFB to C3b and its cleavage was determined in cell-free assays. Macrophage phagocytosis in presence of recombinant CFB or serum from CFB risk, or protective CD or healthy subjects was assessed by flow cytometry. RESULTS: Perianal complications were associated with colonic involvement, OmpC and ASCA serology, and serology quartile sum score. We identified a genetic association for pCD (rs4151651), a non-synonymous SNP (G252S) in CFB, in all three cohorts. Recombinant S252 CFB had reduced binding to C3b, its cleavage was impaired, and complement-driven phagocytosis and cytokine secretion were reduced compared with G252 CFB. Serine 252 generates a de novo glycosylation site in CFB. Serum from homozygous risk patients displayed significantly decreased macrophage phagocytosis compared with non-risk serum. CONCLUSION: pCD-associated rs4151651 in CFB is a loss-of-function mutation that impairs its cleavage, activation of alternative complement pathway, and pathogen phagocytosis thus implicating the alternative complement pathway and CFB in pCD aetiology.

BACKGROUND & AIMS: There are limited data on outcomes of biologic therapy in Hispanic patients with inflammatory bowel diseases (IBDs). We compared risk of hospitalization, surgery, and serious infections in Hispanic vs non-Hispanic patients with IBD in a multicenter, electronic health record-based cohort of biologic-treated patients. METHODS: We identified adult patients with IBD who were new users of biologic agents (tumor necrosis factor α [TNF-α] antagonists, ustekinumab, vedolizumab) from 5 academic institutions in California between 2010 and 2017. We compared the risk of all-cause hospitalization, IBD-related surgery, and serious infections in Hispanic vs non-Hispanic patients using 1:4 propensity score matching and survival analysis. RESULTS: We compared 240 Hispanic patients (53% male; 45% with ulcerative colitis; 73% TNF-α antagonist-treated; 20% with prior biologic exposure) with 960 non-Hispanic patients (51% male; 44% with ulcerative colitis; 67% TNF-α antagonist-treated; 27% with prior biologic exposure). After propensity score matching, Hispanic patients were younger (37 ± 15 vs 40 ± 16 y; P = .02) and had a higher burden of comorbidities (Elixhauser index, >0; 37% vs 26%; P < .01), without any differences in patterns of medication use, burden of inflammation, and hospitalizations. Within 1 year of biologic initiation, Hispanic patients had higher rates of hospitalizations (31% vs 23%; adjusted hazard ratio [aHR], 1.32; 95% CI, 1.01-1.74) and IBD-related surgery (7.1% vs 4.6%; aHR, 2.00; 95% CI, 1.07-3.72), with a trend toward higher risk of serious infections (8.8% vs 4.9%; aHR, 1.74; 95% CI, 0.99-3.05). CONCLUSIONS: In a multicenter, propensity score-matched cohort of biologic-treated patients with IBD, Hispanic patients experienced higher rates of hospitalization, surgery, and serious infections. Future studies are needed to investigate the biological, social, and environmental drivers of these differences.

BACKGROUND & AIMS: We compared the safety and effectiveness of tumor necrosis factor α (TNF-α) antagonists vs vedolizumab vs ustekinumab in patients with Crohn's disease (CD) in a multicenter cohort (CA-IBD). METHODS: We created an electronic health record-based cohort of adult patients with CD who were initiating a new biologic agent (TNF-α antagonists, ustekinumab, vedolizumab) from 5 health systems in California between 2010 and 2017. We compared the risk of serious infections (safety) and all-cause hospitalization and inflammatory bowel disease-related surgery (effectiveness) between different biologic classes using propensity score (PS) matching. RESULTS: As compared with TNF-α antagonists (n = 1030), 2:1 PS-matched, ustekinumab-treated patients with CD (n = 515) experienced a lower risk of serious infections (hazard ratio [HR], 0.36; 95% CI, 0.20-0.64), without any difference in the risk of hospitalization (HR, 0.99; 95% CI, 0.89-1.21) or surgery (HR, 1.08; 95% CI, 0.69-1.70). Compared with vedolizumab (n = 221), 1:1 PS-matched, ustekinumab-treated patients with CD (n = 221) experienced a lower risk of serious infections (HR, 0.20; 95% CI, 0.07-0.60), without significant differences in risk of hospitalization (HR, 0.76; 95% CI, 0.54-1.07) or surgery (HR, 1.42; 95% CI, 0.54-3.72). Compared with TNF-α antagonists (n = 442), 2:1 PS-matched, vedolizumab-treated patients with CD (n = 221) had a similar risk of serious infections (HR, 1.53; 95% CI, 0.84-2.78), hospitalization (HR, 1.32; 95% CI, 0.98-1.77), and surgery (HR, 0.63; 95% CI, 0.27-1.47). High comorbidity burden, concomitant opiate use, and prior hospitalization were associated with serious infections and hospitalization in biologic-treated patients with CD. CONCLUSION: In a multicenter cohort of biologic-treated patients with CD, ustekinumab was associated with a lower risk of serious infections compared with TNF-α antagonists and vedolizumab, without any differences in risk of hospitalization or surgery. The risk of serious infections was similar for TNF-α antagonists vs vedolizumab.

BACKGROUND: Tofacitinib is an oral small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). AIMS: To evaluate real-world data in US patients with UC receiving tofacitinib. METHODS: Characteristics and outcomes of patients with UC initiating tofacitinib between 2018 and 2019 were assessed using data from the IBM® MarketScan® claims database. The index date was the first tofacitinib claim; pre- and post-index periods were 12 months. Outcomes included tofacitinib adherence/persistence, oral corticosteroid (OCS) use, and healthcare resource utilization (HCRU) and costs. RESULTS: Of 276 patients with UC who initiated tofacitinib, 68 (24.6%) were bio-naïve, and 208 (75.4%) bio-experienced. At month 12, overall median tofacitinib adherence (proportion of days covered) was 0.82 (mean 0.68); 43.8% of patients discontinued tofacitinib (90-day gap). Of patients receiving OCS during the post-index 16-week tapering period, 40.4% discontinued OCS up to 12 months post-index. OCS use decreased in patients continuing tofacitinib versus those discontinuing tofacitinib (29.7% vs 59.5%, respectively). Reductions in all-cause and UC-related outpatient visits were observed for bio-naïve (- 1.34 and - 0.88, respectively) and bio-experienced (- 4.72 and - 5.16, respectively) patients, post-index. Decreased UC-related costs per year were observed for bio-experienced patients (difference in post-index vs pre-index, - US$12,448; driven by changes in pharmacy costs), but not for bio-naïve patients (US$47,152). CONCLUSIONS: In this real-world analysis in a mostly bio-experienced population, the majority of US patients with UC initiating tofacitinib remained on therapy at 12 months, and OCS use was reduced with tofacitinib treatment. HCRU (all patients) and UC-related costs were reduced in bio-experienced patients. The majority of patients with ulcerative colitis starting tofacitinib in this real-world study continued therapy at 12 months; there was a reduction in the use of steroids, and a decrease in healthcare resournce utilization and costs.

BACKGROUND: Patients with inflammatory bowel disease (IBD) are at increased risk of infections, bone fractures, and skin cancers. OBJECTIVE: We developed preventive health videos using a patient-centered approach and tested their impact on preventive health uptake. METHODS: Five animated videos explaining preventive health recommendations in IBD were iteratively developed with patient-centered focus groups and interviews. A randomized controlled trial was then conducted in a web-based IBD cohort to test the impact of video- versus text-based educational interventions. The primary outcome was receipt of the influenza vaccine. Secondary outcomes included intention to receive other preventive health services. RESULTS: Five animated videos were developed with patient input. A total of 1056 patients with IBD were then randomized to receive the video (n=511) or text-only (n=545) interventions; 55% (281/511) of the video group and 57% (311/545) of the text-only group had received their influenza vaccine in the prior year. Immediately after the intervention, 73% (502/683) of patients reported their intention to receive the vaccine, with no difference by the type of intervention (75%, 231/307, for the video group and 72%, 271/376, for the text-only group). The proportion of patients who actually received the influenza vaccine after the intervention also did not differ by messaging type (P=.07). The strongest predictor of both intention to receive and actual receipt of the influenza vaccine was prior influenza vaccination. Older age was also associated with a higher likelihood of the intention to receive (age 36-75 years relative to 18-35 years; P=.006) and actual receipt (age >75 years relative to 18-35 years; P=.05) of the influenza vaccine. CONCLUSIONS: The proportion of patients receiving the influenza vaccine was high in both groups, but there was no difference in receipt of or in the intention to receive preventive health recommendations by type of messaging. Notably, a portion of patients in both groups had intended to be vaccinated but did not ultimately receive the vaccine. Further evaluation of patient-education strategies is warranted to improve preventive health uptake among patients with IBD. TRIAL REGISTRATION: ClinicalTrials.gov NCT05997537; https://clinicaltrials.gov/ct2/show/NCT05997537.

INTRODUCTION: To support shared decision-making (SDM) between patients and providers surrounding biologic treatments, we created IBD&me ( ibdandme.org )-a freely available, unbranded, interactive decision aid. We performed a multicenter comparative effectiveness trial comparing the impact of IBD&me on SDM vs a biologics fact sheet developed by the Crohn's & Colitis Foundation. METHODS: We enrolled patients with inflammatory bowel disease (IBD) being seen at a clinic within IBD Qorus-a multicenter adult IBD learning health system-between March 5, 2019, and May 14, 2021. Eligible patients included those with recent IBD-related symptoms who reported that they wanted to discuss biologics with their provider during their upcoming visit. Patients were randomized 1:1 using stratified block randomization and received an e-mail 1 week before their visit inviting them to review either IBD&me or a fact sheet. The primary outcome was patient perception of SDM as measured by the 9-Item SDM Questionnaire (0-100 scale; higher = better); the Student t test was used to compare outcomes between arms. RESULTS: Overall, 152 patients were randomized (biologics fact sheet 75, IBD&me 77); most patients had Crohn's disease (66.4%) and were biologic-experienced (82.9%). No differences were seen between groups regarding SDM (fact sheet 72.6 ± 25.6, IBD&me 75.0 ± 20.8; P = .57). Most patients stated they would be likely to recommend the fact sheet (79.6%) or IBD&me (84.9%; P = .48) to another patient with IBD. DISCUSSION: No differences in outcomes were seen between IBD&me and the biologics fact sheet in this comparative effectiveness study; patients reported high satisfaction with both resources. Further study, particularly among biologic naïve patients, is needed to determine the utility of interactive components to IBD decision aids.

INTRODUCTION: Obesity is variably associated with treatment response in biologic-treated patients with inflammatory bowel diseases (IBD). We evaluated the association between obesity and risk of hospitalization, surgery, or serious infections in patients with IBD in new users of biologic agents in a large, multicenter, electronic health record (EHR)-based cohort (CA-IBD). METHODS: We created an EHR-based cohort of adult patients with IBD who were new users of biologic agents (tumor necrosis factor [TNF-α] antagonists, ustekinumab, and vedolizumab) between January 1, 2010, and June 30, 2017, from 5 health systems in California. Patients were classified as those with normal body mass index (BMI), overweight, or obese based on the World Health Organization classification. We compared the risk of all-cause hospitalization, IBD-related surgery, or serious infections among patients with obesity vs those overweight vs those with normal BMI, using Cox proportional hazard analyses, adjusting for baseline demographic, disease, and treatment characteristics. RESULTS: Of 3,038 biologic-treated patients with IBD (69% with Crohn's disease and 76% on TNF-α antagonists), 28.2% (n = 858) were overweight, and 13.7% (n = 416) were obese. On a follow-up after biologic initiation, obesity was not associated with an increased risk of hospitalization (adjusted hazard ratio [aHR] vs normal BMI, 0.90; [95% confidence interval, 0.72-1.13]); IBD-related surgery (aHR, 0.62 [0.31-1.22]); or serious infection (aHR, 1.11 [0.73-1.71]). Similar results were observed on stratified analysis by disease phenotype (Crohn's disease vs ulcerative colitis) and index biologic therapy (TNF-α antagonists vs non-TNF-α antagonists). DISCUSSION: In a multicenter, EHR-based cohort of biologic-treated patients with IBD, obesity was not associated with hospitalization, surgery, or serious infections. Further studies examining the effect of visceral obesity on patient-reported and endoscopic outcomes are needed.

BACKGROUND & AIMS: Adverse events (AEs) including reactivation of herpes zoster (HZ) and venous thromboembolism (VTE) have been reported from clinical trials of tofacitinib in ulcerative colitis (UC). We investigated the incidence rates of AEs in a real-world study of UC patients given tofacitinib. METHODS: We collected data from 260 patients with UC in the Tofacitinib Real-world Outcomes in Patients with ulceratIve colitis and Crohn's disease consortium study, performed at 6 medical centers in the United States. Patients were followed up for a median of 6 months (interquartile range, 2.7-11.5 mo). AEs were captured using a standardized data collection instrument before study initiation and at weeks 8, 16, 26, 39, and 52. Serious AEs were defined as life-threatening or resulting in a hospitalization, disability, or discontinuation of therapy. Logistic regression was performed to examine risk factors for AEs. RESULTS: AEs occurred in 41 patients (15.7%); most were infections (N = 13; 5.0%). The incidence rate of any AE was 27.2 (95% CI, 24.4-30.7 per 100 patient-years of follow-up evaluation). Fifteen were serious AEs (36.6% of AEs), and tofacitinib was discontinued for 12 patients (4.6% of cohort). The incidence rates of serious AEs was 10.0 (95% CI, 8.9-11.2 per 100 patient-years of follow-up evaluation). Five patients developed HZ infection and 2 developed VTE (all receiving 10 mg tofacitinib, twice per day). CONCLUSIONS: Real-world safety signals for tofacitinib are similar to those for clinical trials, with AEs reported from almost 16% of patients. HZ infection and VTE occurred in patients receiving 10 mg tofacitinib twice per day. These results support dose de-escalation after induction therapy, to reduce the risk of AEs.

INTRODUCTION: Gastroenterologists at all levels of practice benefit from formal mentoring. Much of the current literature on mentoring in gastroenterology is based on expert opinion rather than data. In this study, we aimed to identify gender-related barriers to successful mentoring relationships from the mentor and mentee perspectives. METHODS: A voluntary, web-based survey was distributed to physicians at 20 academic institutions across the United States. Overall, 796 gastroenterology fellows and faculty received the survey link, with 334 physicians responding to the survey (42% response rate), of whom 299 (90%; 129 women and 170 men) completed mentorship questions and were included in analysis. RESULTS: Responses of women and men were compared. Compared with men, more women preferred a mentor of the same gender (38.6% women vs 4.2% men, P < 0.0001) but less often had one (45.5% vs 70.2%, P < 0.0001). Women also reported having more difficulty finding a mentor (44.4% vs 16.0%, P < 0.0001) and more often cited inability to identify a mentor of the same gender as a contributing factor (12.8% vs 0.9%, P = 0.0004). More women mentors felt comfortable advising women mentees about work-life balance (88.3% vs 63.8%, P = 0.0005). Nonetheless, fewer women considered themselves effective mentors (33.3% vs 52.6%, P = 0.03). More women reported feeling pressured to mentor because of their gender (39.5% vs 0.9% of men, P < 0.0001). Despite no gender differences, one-third of respondents reported negative impact of the COVID-19 pandemic on their ability to mentor and be mentored. DISCUSSION: Inequities exist in the experiences of women mentees and mentors in gastroenterology, which may affect career advancement and job satisfaction.

BACKGROUND: Vedolizumab has been proposed to lead to fewer postoperative complications because of its gut specificity. Studies, however, suggest an increased risk of surgical site infections, yet the data are conflicting. OBJECTIVE: This study aimed to assess the effect of vedolizumab drug levels on postoperative outcomes in patients undergoing major abdominal surgery for IBD. DESIGN: This was a retrospective study of a prospectively maintained database. SETTING: Patients were operated on by a single surgeon at an academic medical center. PATIENTS: A total of 72 patients with IBD undergoing major abdominal surgery were included. INTERVENTIONS: Patients were exposed preoperatively to vedolizumab. MAIN OUTCOME MEASURES: The primary outcome measured was the postoperative morbidity in patients who had IBD with detectable vs undetectable vedolizumab levels. RESULTS: A total of 72 patients were included in the study. Thirty-eight patients had detectable vedolizumab levels (>1.6 µg/mL), and 34 had undetectable vedolizumab levels. The overall rate of complications was 39%, and ileus was the most common complication. There were no significant differences in clinical variables between the detectable and undetectable vedolizumab level patient groups except for the time between the last dose and surgery (p < 0.01). There were 42 patients in the ulcerative colitis cohort; 48% had an undetectable vedolizumab level and 52% had a detectable vedolizumab level. There were no differences in any postoperative morbidity between ulcerative colitis groups. The Crohn's cohort had 27 patients; 48% had an undetectable vedolizumab levels and 52% had a detectable vedolizumab level. There was a significantly lower incidence of postoperative ileus in patients who had Crohn's disease with detectable vedolizumab levels compared with patients with an undetectable vedolizumab level (p < 0.04). LIMITATIONS: Limitations include a low overall patient population and a high rate of stoma formation. CONCLUSIONS: Serum vedolizumab levels do not influence postoperative morbidity in IBD. Vedolizumab may reduce the incidence of postoperative ileus in patients with Crohn's disease. See Video Abstract at http://links.lww.com/DCR/B574. LOS NIVELES DE VEDOLIZUMAB EN SUERO PREOPERATORIO, NO AFECTAN LOS RESULTADOS POSTOPERATORIOS EN LA ENFERMEDAD INFLAMATORIA INTESTINAL: ANTECEDENTES:Se ha propuesto que el vedolizumab presenta menos complicaciones postoperatorias debido a su especificidad intestinal. Sin embargo, estudios sugieren un mayor riesgo de infecciones en el sitio quirúrgico, aunque los datos son contradictorios.OBJETIVO:Evaluar el efecto en los niveles del fármaco vedolizumab, en resultados postoperatorios de pacientes sometidos a cirugía mayor abdominal, por enfermedad inflamatoria intestinal.DISEÑO:Estudio retrospectivo de una base de datos mantenida prospectivamente.ENTORNO CLÍNICO:Pacientes intervenidos por un solo cirujano en un centro médico académico.PACIENTES:Un total de 72 pacientes con enfermedad inflamatoria intestinal sometidos a cirugía mayor abdominal.INTERVENCIONES:Exposición preoperatoria a vedolizumab.PRINCIPALES MEDIDAS DE VALORACIÓN:Morbilidad postoperatoria en pacientes con enfermedad inflamatoria intestinal, con niveles detectables versus no detectables de vedolizumab.RESULTADOS:Se incluyó en el estudio a un total de 72 pacientes. Treinta y ocho pacientes tuvieron niveles detectables de vedolizumab (> 1,6 mcg / ml) y 34 con niveles no detectables de vedolizumab. La tasa global de complicaciones fue del 39% y el íleo fue la complicación más común. No hubo diferencias significativas en las variables clínicas entre los grupos de pacientes con niveles detectables y no detectables de vedolizumab, excepto por el intervalo de tiempo entre la última dosis y la cirugía (p <.01). La cohorte de colitis ulcerosa tuvo 42 pacientes, el 48% con un nivel no detectable de vedolizumab y el 52% un nivel detectable de vedolizumab. No hubo diferencias en ninguna morbilidad postoperatoria entre los grupos de colitis ulcerosa. La cohorte de Crohn tuvo 27 pacientes, 48% con niveles no detectables de vedolizumab y el 52% con niveles detectables de vedolizumab. Hubo una incidencia significativamente menor de íleo postoperatorio en pacientes de Crohn con niveles detectables de vedolizumab, comparados con los pacientes con un nivel no detectable de vedolizumab (p <0,04).LIMITACIONES:Las limitaciones incluyen una baja población general de pacientes y una alta tasa de formación de estomas.CONCLUSIONES:Los niveles séricos de vedolizumab no influyen en la morbilidad postoperatoria de la enfermedad inflamatoria intestinal. Vedolizumab puede reducir la incidencia de íleo postoperatorio en pacientes de Crohn. Consulte Video Resumen en http://links.lww.com/DCR/B574.

AIM: Tumour necrosis factor inhibitors (TNFi) have revolutionized the management of moderate to severe ulcerative colitis (UC) since their approval for UC in 2005. However, many patients ultimately require surgery with ileal pouch-anal anastomosis (IPAA). Development of de novo Crohn's disease (CD) following IPAA is an increasingly common and devastating complication, sometimes progressing to pouch failure. The aim of this study was to evaluate the association of preoperative TNFi exposure and the development of de novo CD after IPAA. METHOD: A prospective single-centre inflammatory bowel disease (IBD) registry was searched for consecutive patients with UC undergoing IPAA during a 25-year period ending July 2018. Patients with preoperative CD or IBD-unclassified were excluded. De novo CD was diagnosed upon endoscopic evidence of five or more mucosal ulcers proximal to the ileal pouch any time after surgery and/or pouch fistula occurring more than three months after ileostomy closure. RESULTS: The study cohort consisted of 400 patients with a median follow-up of 44.0 (IQR 11-113) months. Sixty-two (16%) patients developed de novo CD 28.0 (IQR 6-67) months following ileostomy closure. Survival analysis of TNFi era patients revealed a significant increase in de novo CD risk in those with preoperative TNFi exposure. Multivariable proportional hazards modelling revealed two independent predictors for de novo CD development: older age was protective (HR 0.89 per 5-year increase; P = 0.009) and preoperative TNFi exposure was hazardous (HR 2.10; P = 0.011). CONCLUSION: This prospective study is the first to suggest an association between preoperative TNFi exposure and the development of de novo CD.

BACKGROUND AND AIMS: Infliximab rescue therapy is effective in patients with corticosteroid refractory acute severe ulcerative colitis, but predictors of response remain poorly understood. We aimed to identify predictors of colectomy in this high-risk patient population. METHODS: Patients hospitalized with acute severe ulcerative colitis who received infliximab after failing intravenous corticosteroid therapy between July 2012 and June 2017 were retrospectively identified. Stepwise regression with backward elimination was used to identify predictors of colectomy at 90 days and 1 year. Ninety-day and 1-year colectomy rates were compared between the patients who received 5 mg/kg and 10 mg/kg IFX rescue dose. RESULTS: Sixty-three patients met the eligibility criteria. Twenty-nine patients received 5 mg/kg, and 34 received 10 mg/kg infliximab dose. Serum albumin on admission (OR 0.10; p = 0.04) and band neutrophil percentage at the time of infliximab administration (OR 1.21; p = 0.02) were independent predictors of 90-day colectomy. A combination of serum albumin ≤ 2.5 g/dl and band neutrophil count ≥ 13% had a 100% positive predictive value for 90-day colectomy. Unadjusted 90-day and 1-year colectomy rates were similar in the 5 mg/kg and 10 mg/kg infliximab groups. After adjusting for confounding factors, 10 mg/kg infliximab dose was potentially protective for 90-day (OR 0.07; p = 0.06) but not for 1-year colectomy (OR 0.19; p = 0.16). CONCLUSIONS: Bandemia and low serum albumin are independent predictors of failure of infliximab rescue therapy in acute severe ulcerative colitis. Serum albumin ≤ 2.5 g/dl and band neutrophil count ≥ 13% had a 100% positive predictive value for 90-day colectomy.

BACKGROUND: Severe acute refractory colitis has traditionally been an indication for emergent colectomy in IBD, yet under these circumstances patients are at elevated risk for complications because of their heightened inflammatory state, nutritional deficiencies, and immunocompromised state. OBJECTIVE: We hypothesized that rescue diverting loop ileostomy may be a viable alternative to emergent colectomy, providing the opportunity for colonic healing and patient optimization before more definitive surgery. DESIGN: This was a retrospective case series. SETTINGS: The study was conducted at a single academic center. PATIENTS: Patients with severe acute medically refractory IBD-related colitis were included. INTERVENTION: Rescue diverting loop ileostomy was the intervening procedure. MAIN OUTCOME MEASURES: The primary outcome was avoidance of urgent/emergent colectomy. The secondary outcome was efficacy, defined by 3 clinical aims: 1) reduced steroid dependence or opportunity for bridge to medical rescue, 2) improved nutritional status, and 3) ability to undergo an elective laparoscopic definitive procedure or ileostomy reversal with colon salvage. RESULTS: Among 33 patients, 14 had Crohn's disease and 19 had ulcerative colitis. Three patients required urgent/emergent colectomy, 2 with ulcerative colitis and 1 with Crohn's disease. Across both disease cohorts, >80% of patients achieved each clinical aim for efficacy: 88% reduced their steroid dependence or were able to bridge to medical rescue, 87% improved their nutritional status, and 82% underwent an elective laparoscopic definitive procedure or ileostomy reversal. A total of 4 patients (11.7%) experienced a postoperative complication following diversion, including 3 surgical site infections and 1 episode of acute kidney injury. LIMITATIONS: The study was limited by being a single-center, retrospective series. CONCLUSIONS: Rescue diverting loop ileostomy in the setting of severe, refractory IBD-colitis is a safe and effective alternative to emergent colectomy. This procedure has acceptably low complication rates and affords patients time for medical and nutritional optimization before definitive surgical intervention.

BACKGROUND: Cathelicidin (LL-37) is an antimicrobial peptide known to be associated with various autoimmune diseases. We attempt to determine if cathelicidin can accurately reflect IBD disease activity. We hypothesize that serum cathelicidin correlates with mucosal disease activity, stricture, and clinical prognosis of IBD patients. METHODS: Serum samples were collected from two separate cohorts of patients at the University of California, Los Angeles. Cohort 1 consisted of 50 control, 23 UC, and 28 CD patients. Cohort 2 consisted of 20 control, 57 UC, and 67 CD patients. LL-37 levels were determined by ELISA. Data from both cohorts were combined for calculation of accuracies in indicating mucosal disease activity, relative risks of stricture, and odds ratios of predicting disease development. RESULTS: Serum cathelicidin levels were inversely correlated with Partial Mayo Scores of UC patients and Harvey-Bradshaw Indices of CD patients. Among IBD patients with moderate or severe initial disease activity, the patients with high initial LL-37 levels had significantly better recovery than the patients with low initial LL-37 levels after 6-18 months, suggesting that high LL-37 levels correlate with good prognosis. Co-evaluation of LL-37 and CRP levels was more accurate than CRP alone or LL-37 alone in the correlation with Mayo Endoscopic Score of UC patients. Low LL-37 levels indicated a significantly elevated risk of intestinal stricture in CD patients. CONCLUSION: Co-evaluation of LL-37 and CRP can indicate mucosal disease activity in UC patients. LL-37 can predict future clinical activity in IBD patients and indicate risk of intestinal stricture in CD patients.
