RESUMEN
Lymphoid cells that produce interleukin (IL)-17 cytokines protect barrier tissues from pathogenic microbes but are also prominent effectors of inflammation and autoimmune disease. T helper 17 (Th17) cells, defined by RORγt-dependent production of IL-17A and IL-17F, exert homeostatic functions in the gut upon microbiota-directed differentiation from naive CD4+ T cells. In the non-pathogenic setting, their cytokine production is regulated by serum amyloid A proteins (SAA1 and SAA2) secreted by adjacent intestinal epithelial cells. However, Th17 cell behaviors vary markedly according to their environment. Here, we show that SAAs additionally direct a pathogenic pro-inflammatory Th17 cell differentiation program, acting directly on T cells in collaboration with STAT3-activating cytokines. Using loss- and gain-of-function mouse models, we show that SAA1, SAA2, and SAA3 have distinct systemic and local functions in promoting Th17-mediated inflammatory diseases. These studies suggest that T cell signaling pathways modulated by the SAAs may be attractive targets for anti-inflammatory therapies.

BACKGROUND & AIMS: The pivotal phase 3 True North (TN) study demonstrated the efficacy and safety of ozanimod in patients with moderately to severely active ulcerative colitis. This analysis assessed ozanimod during TN and the ongoing open-label extension (OLE) in patients with active disease who were naive to advanced therapies (ATs). METHODS: TN was a randomized, double-blind, placebo-controlled trial consisting of 10-week induction period and 42-week maintenance period. Eligible patients could enter the OLE. Symptomatic efficacy was evaluated from induction through the OLE. Clinical, endoscopic, and mucosal outcomes were evaluated at the end of induction (Week [W] 10) and maintenance (W52) and at predefined OLE timepoints (OLE W46 and W94). Safety during TN was reported. RESULTS: This analysis included 616 AT-naive patients. Numerically greater proportions of patients receiving ozanimod than placebo achieved symptomatic response (39% vs 29%, 95% confidence interval, -0.1 to 18.8) by W2, with significant differences (56% vs 39%, 95% confidence interval, 6.3-26.3) achieved by W4. Patients receiving ozanimod showed significant improvements across efficacy outcomes versus placebo at W10 and W52 (P < .05, all endpoints). In patients on continuous ozanimod who entered the OLE in clinical response at W52, 91% maintained clinical response through OLE W94, and 74% achieved endoscopic improvement and 57% achieved mucosal healing at OLE W94. In ozanimod-treated patients without clinical response by W10 who received extended induction in the OLE, 62% achieved symptomatic response by OLE W10. Safety outcomes in AT-naive patients were consistent with the total TN population. CONCLUSIONS: Ozanimod is an effective, durable, and well-tolerated oral therapy for AT-naive ulcerative colitis patients. CLINICALTRIALS: gov, numbers NCT02435992 and NCT02531126.
RESUMEN
BACKGROUND: Comparisons among autoimmune diseases enable understanding of the burden and factors associated with work productivity loss and impairment. AIMS: The objective was to compare work productivity and activity and associated factors among patients with inflammatory bowel diseases and other autoimmune conditions. METHODS: This cross-sectional study included employed, adult patients (age 20-64 years) in the CorEvitas Inflammatory Bowel Disease, Psoriasis, and Psoriatic Arthritis/Spondyloarthritis Registries between 5/2017 and 6/2020. Any patient-reported impairment on four domains of the Work Productivity and Activity Index (WPAI) was collected across registries. Prevalence for each autoimmune disease was reported and stratified by disease activity using direct age-sex-standardization. Factors associated with the presence of any WPAI were identified in logistic regression models. RESULTS: A total of 7,169 patients with psoriasis (n = 4,768, 67%), psoriatic arthritis (n = 1,208, 17%), Crohn's disease (CD, n = 621, 9%), and ulcerative colitis (UC, n = 572, 8%) met inclusion criteria. Among patients not in remission across all disease cohorts, the age-sex-standardized prevalence of any presenteeism, work productivity loss, and activity impairment ranged from 54 to 97%. Patients with CD in remission had higher standardized prevalence of presenteeism (53% [48-57%]) and work productivity loss (54% [49-59%]), compared to those from other cohorts (presenteeism [range: 33-39%] and work productivity loss [range: 37-41%]). For all WPAI domains, the strongest adjusted associations were for moderate to severe disease activity and psychosocial symptoms. CONCLUSIONS: Patients with moderate to severe disease activity reported the highest WPAI burden. However, patients in remission or mild disease activity also report some WPAI burden, emphasizing a multidisciplinary treatment approach to improve work productivity loss and impairment.
RESUMEN
INTRODUCTION: Older adults with inflammatory bowel disease (IBD) are at higher risk for postoperative complications as compared to their younger counterparts; however, factors contributing to this are unknown. We assessed risk factors associated with adverse IBD-related surgical outcomes, evaluated trends in emergency surgery, and explored differential risks by age. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program database, we identified adults ≥18 years of age who underwent an IBD-related intestinal resection from 2005 to 2019. Our primary outcome included a 30-day composite of mortality, readmission, reoperation, and/or major postoperative complication. RESULTS: Overall, 49,746 intestinal resections were performed with 9,390 (18.8%) occurring among older adults with IBD. Nearly 37% of older adults experienced an adverse outcome as compared to 28.1% among younger adults with IBD ( P < 0.01). Among all adults with IBD, the presence of preoperative sepsis (adjusted odds ratio [aOR], 2.08; 95% confidence interval [CI] 1.94-2.24), malnutrition (aOR, 1.22; 95% CI 1.14-1.31), dependent functional status (aOR, 6.92; 95% CI 4.36-11.57), and requiring emergency surgery (aOR, 1.50; 95% CI 1.38-1.64) increased the odds of an adverse postoperative outcome, with similar results observed when stratifying by age. Furthermore, 8.8% of surgeries among older adults were emergent, with no change observed over time ( P = 0.16). DISCUSSION: Preoperative factors contributing to the risk of an adverse surgical outcome are similar between younger and older individuals with IBD, and include elements such as malnutrition and functional status. Incorporating these measures into surgical decision-making can reduce surgical delays in older individuals at low risk and help target interventions in those at high risk, transforming care for thousands of older adults with IBD.

INTRODUCTION: We evaluated the real-world effectiveness and safety of ustekinumab (UST) in patients with Crohn's disease (CD). METHODS: This study used a retrospective, multicenter, multinational consortium of UST-treated CD patients. Data included patient demographics, disease phenotype, disease activity, treatment history, and concomitant medications. Cumulative rates of clinical, steroid-free, endoscopic, and radiographic remissions were assessed using time-to-event analysis, and clinical predictors were assessed by using multivariate Cox proportional hazard analyses. Serious infections and adverse events were defined as those requiring hospitalization or treatment discontinuation. RESULTS: A total of 1,113 patients (51.8% female, 90% prior antitumor necrosis factor exposure) were included, with a median follow-up of 386 days. Cumulative rates of clinical, steroid-free, endoscopic, and radiographic remissions at 12 months were 40%, 32%, 39%, and 30%, respectively. Biologic-naive patients achieved significantly higher rates of clinical and endoscopic remissions at 63% and 55%, respectively. On multivariable analyses, prior antitumor necrosis factor (hazard ratio, 0.72; 95% confidence interval, 0.49-0.99) and vedolizumab exposure (hazard ratio, 0.65; 95% confidence interval, 0.48-0.88) were independently associated with lower likelihoods of achieving endoscopic remission. In patients who experienced loss of remission, 77 of 102 (75%) underwent dose optimization, and 44 of 77 (57%) achieved clinical response. An additional 152 of 681 patients (22.3%) were dose-optimized because of primary nonresponse incomplete response to UST, of whom 40.1% (61 of 152) responded. Serious infections occurred in 3.4% of patients while other noninfectious adverse events (lymphoma [n = 1], arthralgia [n = 6], rash [n = 6], headache [n = 3], hepatitis [n = 3], hair loss [n = 3], neuropathy [n = 1], and vasculitis [n = 1]) occurred in 2.4% of patients. DISCUSSION: UST represents a safe and effective treatment option for CD, with 40% of patients from a highly refractory cohort achieving clinical remission by 12 months. The greatest treatment effect of UST was seen in biologic-naive patients, and dose escalation may recapture clinical response.

BACKGROUND & AIMS: Restorative proctocolectomy with ileal pouch-anal anastomosis is a surgical procedure in patients with ulcerative colitis refractory to medical therapies. Pouchitis, the most common complication, is inflammation of the pouch of unknown etiology. To define how the intestinal immune system is distinctly organized during pouchitis, we analyzed tissues from patients with and without pouchitis and from patients with ulcerative colitis using single-cell RNA sequencing (scRNA-seq). METHODS: We examined pouch lamina propria CD45+ hematopoietic cells from intestinal tissues of ulcerative colitis patients with (n = 15) and without an ileal pouch-anal anastomosis (n = 11). Further in silico meta-analysis was performed to generate transcriptional interaction networks and identify biomarkers for patients with inflamed pouches. RESULTS: In addition to tissue-specific signatures, we identified a population of IL1B/LYZ+ myeloid cells and FOXP3/BATF+ T cells that distinguish inflamed tissues, which we further validated in other scRNA-seq datasets from patients with inflammatory bowel disease (IBD). Cell-type-specific transcriptional markers obtained from scRNA-seq was used to infer representation from bulk RNA sequencing datasets, which further implicated myeloid cells expressing IL1B and S100A8/A9 calprotectin as interacting with stromal cells, and Bacteroidales and Clostridiales bacterial taxa. We found that nonresponsiveness to anti-integrin biologic therapies in patients with ulcerative colitis was associated with the signature of IL1B+/LYZ+ myeloid cells in a subset of patients. CONCLUSIONS: Features of intestinal inflammation during pouchitis and ulcerative colitis are similar, which may have clinical implications for the management of pouchitis. scRNA-seq enables meta-analysis of multiple studies, which may facilitate the identification of biomarkers to personalize therapy for patients with IBD. The processed single cell count tables are provided in Gene Expression Omnibus; GSE162335. Raw sequence data are not public and are protected by controlled-access for patient privacy.

BACKGROUND & AIMS: We aimed to compare safety and effectiveness of vedolizumab to tumor necrosis factor (TNF)-antagonist therapy in ulcerative colitis in routine practice. METHODS: A multicenter, retrospective, observational cohort study (May 2014 to December 2017) of ulcerative colitis patients treated with vedolizumab or TNF-antagonist therapy. Propensity score weighted comparisons for development of serious adverse events and achievement of clinical remission, steroid-free clinical remission, and steroid-free deep remission. A priori determined subgroup comparisons in TNF-antagonist-naïve and -exposed patients, and for vedolizumab against infliximab and subcutaneous TNF-antagonists separately. RESULTS: A total of 722 (454 vedolizumab, 268 TNF antagonist) patients were included. Vedolizumab-treated patients were more likely to achieve clinical remission (hazard ratio [HR], 1.651; 95% confidence interval [CI], 1.229-2.217), steroid-free clinical remission (HR, 1.828; 95% CI, 1.135-2.944), and steroid-free deep remission (HR, 2.819; 95% CI, 1.496-5.310) than those treated with TNF antagonists. Results were consistent across subgroup analyses in TNF-antagonist-naïve and -exposed patients, and for vedolizumab vs infliximab and vs subcutaneous TNF-antagonist agents separately. Overall, there were no statistically significant differences in the risk of serious adverse events (HR, 0.899; 95% CI, 0.502-1.612) or serious infections (HR, 1.235; 95% CI, 0.608-2.511) between vedolizumab-treated and TNF-antagonist-treated patients. However, in TNF-antagonist-naïve patients, vedolizumab was less likely to be associated with serious adverse events than TNF antagonists (HR, 0.192; 95% CI, 0.049-0.754). CONCLUSIONS: Treatment of ulcerative colitis with vedolizumab is associated with higher rates of remission than treatment with TNF-antagonist therapy in routine practice, and lower rates of serious adverse events in TNF-antagonist-naïve patients.

INTRODUCTION: Limited guidance exists for the postdischarge care of patients with ulcerative colitis hospitalized for moderate-severe flares. METHODS: RAND methodology was used to establish appropriateness of inpatient and postdischarge steroid dosing, discharge criteria, follow-up, and postdischarge biologic or small molecule initiation. A literature review informed on the panel's voting, which occurred anonymously during 2 rounds before and after a moderated virtual session. RESULTS: Methylprednisolone 40-60 mg intravenous every 24 hours or hydrocortisone 100 mg intravenous 3 times daily is appropriate for inpatient management, with methylprednisolone 40 mg being appropriate if intolerant of higher doses. It is appropriate to discharge patients once rectal bleeding has resolved (Mayo subscore 0-1) and/or stool frequency has returned to baseline frequency and form (Mayo subscore 0-1). It is appropriate to discharge patients on 40 mg of prednisone after observing patients for 24 hours in hospital to ensure stability before discharge. For patients being discharged on steroids without in-hospital biologic or small molecule therapy initiation, it is appropriate to start antitumor necrosis factor (TNF) therapy after discharge for anti-TNF-naive patients. For anti-TNF-exposed patients, it is appropriate to start vedolizumab or ustekinumab for all patients and tofacitinib for those with a low risk of adverse events. It is appropriate to follow up patients clinically within 2 weeks and with lower endoscopy within 4-6 months after discharge. DISCUSSION: We provide recommendations on the inpatient and postdischarge management of patients with ulcerative colitis hospitalized for moderate-severe flares.

A goal in precision medicine is to use patient-derived material to predict disease course and intervention outcomes. Here, we use mechanistic observations in a preclinical animal model to design an ex vivo platform that recreates genetic susceptibility to T-cell-mediated damage. Intestinal graft-versus-host disease (GVHD) is a life-threatening complication of allogeneic hematopoietic cell transplantation. We found that intestinal GVHD in mice deficient in Atg16L1, an autophagy gene that is polymorphic in humans, is reversed by inhibiting necroptosis. We further show that cocultured allogeneic T cells kill Atg16L1-mutant intestinal organoids from mice, which was associated with an aberrant epithelial interferon signature. Using this information, we demonstrate that pharmacologically inhibiting necroptosis or interferon signaling protects human organoids derived from individuals harboring a common ATG16L1 variant from allogeneic T-cell attack. Our study provides a roadmap for applying findings in animal models to individualized therapy that targets affected tissues.

BACKGROUND: True North is a phase 3, randomized, double-blind, placebo-controlled trial conducted at 285 sites in 30 countries (NCT02435992). Treatment with once-daily ozanimod (an oral sphingosine 1-phosphate [S1P] receptor modulator selectively targeting S1P1 and S1P5) in patients with moderately-to-severely active ulcerative colitis (UC) showed significant improvements in primary and all key secondary endpoints. Here we report findings on the consistency of clinical and endoscopic endpoints in the global and North American population. METHODS: In True North, patients received either double-blind treatment with ozanimod 0.92 mg (equivalent to ozanimod HCl 1 mg) or matching placebo, or open-label ozanimod 0.92 mg over a 10-week induction period. Patients with clinical response to ozanimod at Week 10 were re-randomized 1:1 to receive double-blind maintenance treatment with ozanimod 0.92 mg or placebo through Week 52. The primary endpoint was proportion of patients in clinical remission at Weeks 10 and 52; key secondary endpoints included clinical response and endoscopic improvement. The global population included 1012 patients who received at least 1 dose of study medication during induction, and 457 who received at least 1 dose of study medication during maintenance. Here, we examine the results from the patients in the North American sites. RESULTS: A total of 247 patients were enrolled in North America, of which 167 received double-blind ozanimod (n=107) or placebo (n=60) during induction. At baseline, 41.1% and 48.3% of patients in the ozanimod and placebo groups, respectively, had previously received a biologic treatment for UC. At Week 10, 15.9% and 3.3% of patients in the ozanimod and placebo groups, respectively, achieved clinical remission. In addition, 46.7% and 15.0% achieved clinical response and 26.2% and 10.0% achieved endoscopic improvement in the ozanimod and placebo groups, respectively. In patients with prior exposure to tumor necrosis factor inhibitor (TNFi), the proportion with clinical response favored ozanimod (35.7%) vs placebo (11.5%), while the proportion with clinical remission and endoscopic improvement did not favor ozanimod. In patients with no prior TNFi exposure, greater responses were seen with ozanimod vs placebo for all 3 endpoints. During maintenance, 105 patients from North America were re-randomized to treatment with ozanimod (n=56) or placebo (n=49). At Week 52, 39.3% and 12.2% of patients in the ozanimod and placebo groups, respectively, achieved clinical remission. In addition, 58.9% and 26.5% achieved clinical response and 50.0% and 16.3% achieved endoscopic improvement in the ozanimod and placebo groups, respectively. The proportion of patients with clinical remission, clinical response, and endoscopic improvement favored ozanimod vs placebo regardless of prior TNFi use. These outcomes from the North American population are generally consistent with those previously reported from the global population. CONCLUSION: In this post-hoc analysis, consistent with the global population, ozanimod treatment for up to 52 weeks in North American patients with moderately-to-severely active UC showed benefits on clinical and endoscopic endpoints.
RESUMEN
INTRODUCTION: There is significant variation in processes and outcomes of care for patients with inflammatory bowel disease (IBD), suggesting opportunities to improve quality of care. We aimed to determine whether a structured quality of care program can improve IBD outcomes, including the need for unplanned health care utilization. METHODS: We used a structured approach to improve adult IBD care in 27 community-based gastroenterology practices and academic medical centers. Patient-reported outcomes (PRO) and health care utilization were collected at clinical visits. Outcomes were monitored monthly using statistical process control charts; improvement was defined by special cause (nonrandom) variation over time. Multivariable logistic regression was applied to patient-level data. Nineteen process changes were offered to improve unplanned health care utilization. Ten outcomes were assessed, including disease activity, remission status, urgent care need, recent emergency department use, hospitalizations, computed tomography scans, health confidence, corticosteroid or opioid use, and clinic phone calls. RESULTS: We collected data prospectively from 20,382 discrete IBD visits. During the 15-month project period, improvement was noted across multiple measures, including need for urgent care, hospitalization, steroid use, and opioid utilization. Adjusted multivariable modeling showed significant improvements over time across multiple outcomes including urgent care need, health confidence, emergency department utilization, hospitalization, corticosteroid use, and opioid use. Attendance at monthly coached webinars was associated with improvement. DISCUSSION: Outcomes of IBD care were improved using a structured quality improvement program that facilitates small process changes, sharing of best practices, and ongoing feedback. Spread of these interventions may facilitate broad improvement in IBD care when applied to a large population.

BACKGROUND: There is wide variation in the quality of care of hospitalized patients with inflammatory bowel disease (IBD). Prior studies have demonstrated that a specialized inpatient IBD service improves short-term outcomes. In this study, we assessed the impact of a dedicated IBD service on the quality of care and long-term outcomes. METHODS: This retrospective cohort study included adult patients admitted for a complication of IBD between March 2017 and February 2019 to a tertiary referral center. In March 2018, a dedicated inpatient IBD service co-managed by IBD gastroenterologists and colorectal surgeons was implemented. Quality of care outcomes included C. difficile stool testing, confirmed VTE prophylaxis administration and opiate avoidance. Long-term outcomes were clinical remission, IBD-related surgery, ED visits, and hospital readmissions at 90 days and 12 months. RESULTS: In total, 143 patients were included; 66 pre- and 77 post-implementation of the IBD service. Fifty-two percent had ulcerative colitis and 48% had Crohn's disease. After implementation, there was improvement in C.difficile testing (90% vs. 76%, P = 0.04), early VTE prophylaxis (92% vs. 77%, P = 0.01) and decreases in narcotic use (14% vs. 30%, P = 0.02), IBD-related ED visits at 90 days (7% vs 18%, P = 0.03) and 12 months (16% vs 30%, P = 0.04), and IBD readmissions at 90 days (16% vs. 30%, P = 0.04). There were no differences in rates of clinical remission or surgery. CONCLUSIONS: The creation of a dedicated inpatient IBD service improved quality of IBD care and reduced post-discharge ED visits and readmissions and broader implementation of this strategy may help optimize care of hospitalized IBD patients.

GOALS AND BACKGROUND: Ustekinumab (UST) is a monoclonal antibody inhibitor of IL-12/IL-23 approved for the treatment of Crohn's disease (CD) and ulcerative colitis (UC). We conducted a meta-analysis to compare rates of adverse events (AEs) in randomized controlled trials (RCTs) of UST for all indications. STUDY: A systematic search was performed of MEDLINE, Embase, and PubMed databases through November 2019. Study inclusion included RCTs comparing UST to placebo or other biologics in patients aged 18 years or older with a diagnosis of an autoimmune condition. RESULTS: Thirty RCTs with 16,068 patients were included in our analysis. Nine thousand six hundred and twenty-six subjects were included in the UST vs placebo analysis. There was no significant difference in serious or mild/moderate AEs between UST and placebo with an OR of 0.83 (95% CI 0.66, 1.05) and 1.08 (95% CI 0.99, 1.18), respectively, over a median follow-up time of 16 weeks. In a sub-analysis of CD and UC trials, no difference in serious or mild/moderate AEs in UST versus placebo was seen. CONCLUSIONS: UST was not associated with an increase in short-term risk of AEs.

BACKGROUND & AIMS: Exposure to hormone contraception has been associated with an increased risk of relapse of inflammatory bowel diseases (IBDs). Little is known about the effects of cancer therapies, specifically hormone therapies, on the course of IBD. METHODS: We conducted a retrospective cohort study, collecting data from 5 medical centers, on patients with IBD who received a subsequent diagnosis of breast or prostate cancer from 1997 through 2018. For patients with quiescent IBD at their cancer diagnosis, the primary outcome was relapse of IBD. For patients with active IBD at their cancer diagnosis, the primary outcome was IBD remission. RESULTS: Our analysis included 447 patients with IBD (44% with Crohn's disease, 53% with ulcerative colitis, and 3% with IBD unclassified) who had either breast (78%) or prostate (22%) cancer. At their cancer diagnosis, 400 patients (90%) had inactive IBD, and 47 (10%) had active IBD. Among patients with inactive IBD, 112 (28%) developed active IBD. Previous exposure to steroids, immunomodulators, or biologics was associated with IBD relapse after a cancer diagnosis (hazard ratio [HR] for steroids, 1.79; 95% CI, 1.18-2.71; HR for immunomodulators, 2.22; 95% CI, 1.38-3.55; HR for biologics, 1.95; 95% CI, 1.01-5.36). Hormone monotherapy (HR, 2.00; 95% CI, 1.21-3.29) and combination cytotoxic and hormone therapy (HR, 1.86; 95% CI, 1.01-3.43) was associated with IBD relapse. Among 34 patients who received only cytotoxic chemotherapy, 75% remained in remission from IBD at 250 months compared with 42% of those who received hormone monotherapy (log rank, 0.02). Among patients with active IBD at their cancer diagnosis, 14 (30%) entered remission from IBD, but there were no significant factors of achieving IBD remission. CONCLUSIONS: In a multicenter retrospective study, we found that patients with IBD and breast or prostate cancer who receive hormone therapy have an increased risk for relapse of IBD and related adverse outcomes.

BACKGROUND & AIMS: We created and validated a clinical decision support tool (CDST) to predict outcomes of vedolizumab therapy for ulcerative colitis (UC). METHODS: We performed logistic regression analyses of data from the GEMINI 1 trial, from 620 patients with UC who received vedolizumab induction and maintenance therapy (derivation cohort), to identify factors associated with corticosteroid-free remission (full Mayo score of 2 or less, no subscore above 1). We used these factors to develop a model to predict outcomes of treatment, which we called the vedolizumab CDST. We evaluated the correlation between exposure and efficacy. We validated the CDST in using data from 199 patients treated with vedolizumab in routine practice in the United States from May 2014 through December 2017. RESULTS: Absence of exposure to a tumor necrosis factor (TNF) antagonist (+3 points), disease duration of 2 y or more (+3 points), baseline endoscopic activity (moderate vs severe) (+2 points), and baseline albumin concentration (+0.65 points per 1 g/L) were independently associated with corticosteroid-free remission during vedolizumab therapy. Patients in the derivation and validation cohorts were assigned to groups of low (CDST score, 26 points or less), intermediate (CDST score, 27-32 points), or high (CDST score, 33 points or more) probability of vedolizumab response. We observed a statistically significant linear relationship between probability group and efficacy (area under the receiver operating characteristic curve, 0.65), as well as drug exposure (P < .001) in the derivation cohort. In the validation cohort, a cutoff value of 26 points identified patients who did not respond to vedolizumab with high sensitivity (93%); only the low and intermediate probability groups benefited from reducing intervals of vedolizumab administration due to lack of response (P = .02). The vedolizumab CDST did not identify patients with corticosteroid-free remission during TNF antagonist therapy. CONCLUSIONS: We used data from a trial of patients with UC to develop a scoring system, called the CDST, which identified patients most likely to enter corticosteroid-free remission during vedolizumab therapy, but not anti-TNF therapy. We validated the vedolizumab CDST in a separate cohort of patients in clinical practice. The CDST identified patients most likely to benefited from reducing intervals of vedolizumab administration due to lack of initial response. ClinicalTrials.gov no: NCT00783718.

PURPOSE OF REVIEW: Treating moderate-to-severe inflammatory bowel disease has become increasingly complex as the array of available biologics increases. Moreover, tofacitinib, the first small molecule approved for IBD, is available for use in ulcerative colitis. Choosing the right biologic, for the right patient, at the right time, can be a confusing and daunting task for clinicians. RECENT FINDINGS: In this review, we summarize the evidence for first-line use of the available biologics by disease state. Special circumstances for consideration including rapidity of action, safety, comparative effectiveness, postoperative Crohn's disease, fertility and pregnancy, and extraintestinal manifestations are discussed. In the moderate-to-severe UC patient, vedolizumab and infliximab are preferred first-line options. In the moderate-to-severe CD patient with a penetrating phenotype or with multiple EIMs, infliximab or adalimumab are the preferred first-line agents. In the moderate-to-severe CD patient with an inflammatory phenotype, anti-TNF, vedolizumab, and ustekinumab are all reasonable options.

BACKGROUND: Postoperative ileus (POI) is a temporary delay of coordinated intestinal peristalsis. Alvimopan, an oral peripherally acting mu-opioid receptor antagonist approved for accelerating gastrointestinal recovery, has never been studied specifically in patients with inflammatory bowel disease (IBD). AIM: To investigate the efficacy of alvimopan in preventing POI among IBD patients. METHODS: A retrospective chart review was conducted on 246 IBD patients undergoing bowel surgery between 2012 and 2017. Data collected included demographics, IBD subtype, length of stay (LOS), postoperative gastrointestinal symptoms, and administration of alvimopan. The primary outcome was POI; secondary gastrointestinal recovery outcomes were: time to first flatus, time to first bowel movement, time to tolerating a liquid diet, time to tolerating solid food, and LOS. RESULTS: When compared with the control group, patients in the alvimopan group had shorter times to tolerating liquids and solids, first flatus, and first bowel movements (p < 0.01). LOS was shorter in the alvimopan group when compared with controls (p < 0.01). The overall incidence of POI was higher in controls than in the alvimopan group (p = 0.07). For laparoscopic surgeries, the incidence of POI was also higher in controls than in the alvimopan group (p < 0.01). On multivariable analysis, alvimopan significantly decreased time to all gastrointestinal recovery endpoints when compared to controls (p < 0.01). CONCLUSIONS: Alvimopan is effective in accelerating time to gastrointestinal recovery and reducing POI in IBD patients. While the benefits of alvimopan have been demonstrated previously, this is the first study of the efficacy of alvimopan in IBD patients.

BACKGROUND & AIMS: There are few real-world data on the safety of vedolizumab for treatment of Crohn's disease (CD) or ulcerative colitis (UC). We quantified rates and identified factors significantly associated with infectious and non-infectious adverse events in clinical practice. METHODS: We performed a retrospective review of data from a multicenter consortium database (from May 2014 through June 2017). Infectious and non-infectious adverse events were defined as those requiring antibiotics, hospitalization, vedolizumab discontinuation, or resulting in death. Rates were quantified as proportions and events per 100 patient years of exposure (PYE) or follow up (PYF). We performed multivariable logistic regression analyses to identify factors significantly associated with events and reported as odds ratios (OR) with 95% CIs. RESULTS: Our analysis comprised 1087 patients (650 with CD and 437 with UC; 55% female; median age, 37 years) with 861 PYE and 955 PYF. Infections were observed in 68 patients (6.3%; 7.9 per 100 PYE, 7.1 per 100 PYF); gastrointestinal infections (n = 31, 2.4 per 100 PYE, 2.2 per 100 PYF) and respiratory infections (n = 14, 1.6 per 100 PYE, 1.5 per 100 PYF) were the most common. Arthralgias were the most common non-infectious adverse events (n = 31, 2.9%; 3.6 per 100 PYE). Two patients developed malignancies (squamous cell skin cancer and colorectal cancer; 0.23 per 100 PYE, 0.21 per 100 PYF). Active smoker status (OR, 3.39) and number of concomitant immunosuppressive agents (corticosteroids or immunomodulators; OR, 1.72 per agent) used were independently associated with infections. CONCLUSION: In a retrospective cohort study of patients with IBD, we found vedolizumab to be well tolerated with an overall favorable safety profile. Active smoking and concomitant use of immunosuppressive agents were independently associated with infections.
