RESUMEN
BACKGROUND: Patients with medically-refractory ulcerative colitis or advanced neoplasia are often offered an ileal-pouch-anal anastomosis to restore bowel continuity. However, up to 50% of patients can suffer from inflammatory conditions of the pouch, some of which require biological therapy to treat. The aim of this study was to determine the efficacy of each biological agent for the treatment of inflammatory conditions of the pouch. MATERIALS AND METHODS: A comprehensive literature search was performed in the major databases from inception through February 11, 2020, for studies assessing the efficacy of biologics in chronic antibiotic-refractory pouchitis (CARP) and Crohn's disease (CD) of the pouch. Both prospective and retrospective studies were included. The primary outcomes of interest were complete and partial responses were defined within each study. χ 2 test was used to compare variables. RESULTS: Thirty-four studies were included in the systematic review and meta-analysis. Sixteen studies (N=247) evaluated the use of infliximab (IFX), showing complete response in 50.7% and partial response in 28.1% for CARP, and complete response in 66.7% and partial response in 20% for CD of the pouch. Seven studies (n=107) assessed the efficacy of adalimumab. For CARP, 33.3% of patients had a complete response, and 38.1% had a partial response, whereas for CD of the pouch, 47.7% experienced a complete response, and 24.6% had a partial response. Three studies (n=78) reported outcomes with the use of ustekinumab, showing 50% complete response and 3.8% partial response for CARP. For the CD of the pouch, 5.8% had a complete response and 78.8% had a partial response. Seven studies (n=151) reported the efficacy of vedolizumab, showing 28.4% complete response and 43.2% partial response in patients with CARP, whereas 63% of patients experienced partial response in CD of the pouch. IFX had higher rates of complete response in CARP compared with adalimumab ( P =0.04) and compared with vedolizumab ( P =0.005), but not compared with ustekinumab ( P =0.95). There were no new safety signals reported in any of the studies. CONCLUSIONS: Biologics are safe and efficacious in the treatment of chronic, refractory inflammatory conditions of the pouch. IFX seems to be more efficacious than adalimumab and vedolizumab for CARP. Further prospective, head-to-head evaluations are needed to compare biological therapies in the treatment of CARP and CD of the pouch.

BACKGROUND & AIMS: This study aimed (1) to systematically review controlled trials of solid food diets for the treatment of inflammatory bowel disease (IBD); and (2) to grade the overall quality of evidence. METHODS: Systematic review of prospective controlled trials of solid food diets for the induction or maintenance of remission in IBD. Two authors independently performed study selection, data extraction, and assessment of certainty of evidence. Meta-analyses were performed on studies with quantitative data on response, remission, and relapse. RESULTS: There were 27 studies for meta-analysis. For induction of remission in Crohn's disease (CD), low refined carbohydrate diet and symptoms-guided diet outperformed controls, but studies had serious imprecision and very low certainty of evidence. The Mediterranean diet was similar to the Specific Carbohydrate Diet (low certainty of evidence), and partial enteral nutrition (PEN) was similar to exclusive enteral nutrition (very low certainty of evidence). PEN reduced risk of relapse (very low certainty of evidence), whereas reduction of red meat or refined carbohydrates did not (low certainty of evidence). For ulcerative colitis, diets were similar to controls (very low and low certainty of evidence). CONCLUSIONS: Among the most robust dietary trials in IBD currently available, certainty of evidence remains very low or low. Nonetheless, emerging data suggest potential benefit with PEN for induction and maintenance of remission in CD. Reduction of red meat and refined carbohydrates might not reduce risk of CD relapse. As more dietary studies become available, the certainty of evidence could improve, thus allowing for more meaningful recommendations for patients.

Perianal Crohn's disease affects 25%-35% of patients with Crohn's disease and has proven to be one of the most difficult complications of the disease to treat. Patients with perianal Crohn's disease have lower health-related quality of life scores typically related to pain and fecal incontinence. In addition, patients with perianal Crohn's disease have higher rates of hospitalizations, surgeries, and overall healthcare costs. A multidisciplinary approach is necessary for the successful management of Crohn's disease with perianal fistula. Medical management is required to treat the underlying immune dysregulation to heal the luminal inflammation and the inflammation within the fistula tracts. Current options for medical therapy include biologics, dual therapy with thiopurines, therapeutic drug monitoring, and a close follow-up. Surgical management is critical to drain abscesses before immunosuppressive therapy and place setons when appropriate. Once the patient's inflammatory burden is well managed, definitive surgical therapies including fistulotomies, advancement flaps, and ligation of intersphincteric fistula tract procedures can be considered. Most recently, the use of stem cell therapy in the treatment of perianal fistula has given new hope to the cure of perianal fistula in Crohn's disease. This review will outline the most current data in the medical and surgical management of perianal Crohn's disease.

BACKGROUND: Perianal fistula is a debilitating disease and challenging condition to treat. Recently, the use of stem cells has been shown to improve healing of fistulas. OBJECTIVE: The aim was to examine the use of an umbilical cord-derived stem cell graft in a pilot study as a novel scaffold/stem inlay implanted into fistula repairs for anovaginal fistula to examine healing rates. DESIGN: This was a pilot study. SETTINGS: This study took place in a colorectal surgery practice. PATIENTS: Patients with anovaginal fistula consented to participate. Cryopreserved umbilical cord tissue graft with viable cells was incorporated as an inlay using a previously reported technique by the authors. Demographic data including history of previous repairs and IBD were included. All patients were followed for a minimum of 6 weeks. MAIN OUTCOME MEASURES: The primary measures were safety and efficacy of novel stem cell graft in the treatment of anovaginal fistula. RESULTS: From September 2017 to September 2019, 15 patients underwent anovaginal fistula repair. Three of these patients underwent a second repair, for a total of 18 repairs. No patient was intentionally diverted, but 3 patients presented for repair with a preexisting stoma. The majority of repairs were previous repair failures (12; 67%), and 7 repairs were performed on 5 patients with IBD. Median follow-up was 30 (6-104) weeks. The safety profile for cryopreserved umbilical cord tissue graft was excellent as no adverse events occurred. Overall complete healing rate was 39%, and 12 (67%) repairs resulted in improvement of symptoms. LIMITATIONS: This was a small pilot study. CONCLUSIONS: This is the largest series using cryopreserved umbilical cord graft for anovaginal fistula repair. The use of umbilical cord was safe and effective at closing defects. Randomized studies are necessary to determine added benefits over current standard of care. See Video Abstract at http://links.lww.com/DCR/B896 .

BACKGROUND: Perianal Crohn's disease is associated with poor outcomes and high medical costs. It is notoriously difficult to treat despite therapeutic advancements for luminal disease. A large animal model that mimics human perianal disease is needed to test innovative therapies. OBJECTIVE: This study aimed to create a swine model that replicates the inflammatory component and therapeutic challenges found in patients with perianal Crohn's disease. DESIGN: This was an animal preclinical study. SETTINGS: The experiments were performed at the animal laboratory at the Johns Hopkins University. PATIENTS: Four sus scrufus female pigs were included in the study. INTERVENTIONS: Four female pigs underwent creation of 3 surgical perianal fistulas each, 1 rectovaginal and 2 perianal. Size 24 French setons were placed to maintain patency of the fistula tracts for 4 weeks. After removal of the setons, trinitrobenzene sulfonic acid was administered into the fistula tract to create and maintain local inflammation mimicking perianal Crohn's disease. MAIN OUTCOMES MEASURES: An MRI was obtained to assess the fistulas and the pigs were euthanized to review histopathology. RESULTS: Three inflammatory chronic fistula tracts were successfully created in each pig as confirmed by MRI and examination under anesthesia. This is the first report of maintaining patent fistulas in swine 2 weeks after removal of setons. For the first time, we reported that 2 pigs developed branching fistulas and small abscesses reminiscent of human perianal Crohn's disease. The corresponding histopathologic examination found significant chronic active inflammation on standard hematoxylin and eosin staining. LIMITATIONS: The fistulas were surgically induced and did not occur naturally. CONCLUSIONS: A chronic perianal fistula model in pigs that strongly resembles human perianal Crohn's disease was successfully created. This model can be used to test novel therapeutics and techniques to pave the path for human trials. See Video Abstract at http://links.lww.com/DCR/B969 . UN NUEVO MODELO PORCINO SIMILAR A UN PACIENTE DE LA ENFERMEDAD DE CROHN PERIANAL ANTECEDENTES: La enfermedad de Crohn perianal se asocia con malos resultados y altos costos médicos. Es notoriamente difícil de tratar a pesar de los avances terapéuticos para la enfermedad luminal. Se precisa de un modelo animal grande que imite la enfermedad perianal humana para probar terapias innovadoras.OBJETIVO:Nuestro objetivo de este estudio fue crear un modelo porcino que replique el componente inflamatorio y los desafíos terapéuticos que se encuentran en los pacientes con enfermedad de Crohn perianal.DISEÑO:Este fue un estudio preclínico en animales.AJUSTES:Los experimentos se realizaron en el laboratorio de animales de la Universidad Johns Hopkins.PACIENTES:Se incluyeron en el estudio cuatro cerdas sus scrofa.INTERVENCIONES:Cuatro cerdas fueron sometidas a la creación de 3 fístulas perianales quirúrgicas cada una: 1 recto vaginal y 2 perianales. Se colocaron sedales de 24 French para mantener la permeabilidad de los trayectos fistulosos durante 4 semanas. Tras el retiro de los sedales, se administró ácido trinitrobenceno sulfónico en el trayecto de la fístula para crear y mantener la inflamación local simulando la enfermedad de Crohn perianal.PRINCIPALES MEDIDAS DE RESULTADOS:Se obtuvo una resonancia magnética para evaluar las fístulas y los cerdos fueron sacrificados para revisar la histopatología.RESULTADOS:Se crearon de manera exitosa tres trayectos fistulosos inflamatorios crónicos en cada cerdo, confirmados por imágenes de resonancia magnética y examen bajo anestesia. Este es el primer informe de preservación de fístulas permeables en cerdos 2 semanas tras el retiro de los setones. Por primera vez, informamos que dos cerdos desarrollaron fístulas ramificadas y pequeños abscesos que recuerdan a la enfermedad de Crohn perianal humana. El examen histopatológico correspondiente encontró una significativa inflamación crónica activa en la tinción estándar de hematoxilina y eosina.LIMITACIONES:Las fístulas se indujeron quirúrgicamente y no se produjeron de forma natural.CONCLUSIONES:Se logro recrear con éxito un modelo de fístula perianal crónica en cerdos que se asemeja mucho a la enfermedad de Crohn perianal humana. Este modelo se puede utilizar para probar nuevas terapias y técnicas para allanar el camino para los ensayos en humanos. Consulte Video Resumen en http://links.lww.com/DCR/B969 .

Iron deficiency anemia affects approximately 45% of patients with inflammatory bowel disease (IBD), negatively impacts the quality of life in this patient population, and significantly burdens our healthcare system. The pathogenesis of iron deficiency in IBD patients is multifactorial, including intestinal bleeding, malabsorption, and inadequate oral intake. Regular screening and diagnosis in these patients are imperative, and often patients have mixed iron deficiency anemia and anemia of chronic disease, especially in those with active inflammation. Iron may be replenished either orally or intravenously. While oral iron is safe, affordable, and easy to administer, patients often suffer from intolerable gastrointestinal side effects, and particularly in IBD patients, oral iron may increase inflammation and contribute to flares. Therefore, although it is substantially underused, intravenous (IV) iron is considered first-line treatment for patients with active disease, severe anemia, oral iron intolerance, and erythropoietin requirements. Several IV iron formulations are available, and iron sucrose and ferric carboxymaltose are the most frequently used and well studied in patients with IBD. However, iron isomaltoside could potentially become a popular choice among providers given its safety, efficacy, and convenience. Overall, screening, diagnosis, and treatment of iron deficiency anemia are important in patients with IBD. Individual patient characteristics, risks, and benefits, and advantages and disadvantages, should be considered when determining the best route and formulation for iron repletion.

BACKGROUND: Crohn's disease perianal fistulae (CD-PAF) occur in 25% of patients and are notoriously challenging to manage. Tumor necrosis factor inhibitors are first line agents. AIMS: The aim of this study was to compare infliximab (IFX) versus adalimumab (ADA) efficacy in CD-PAF healing over time. METHODS: A retrospective study at two large-tertiary medical centers was performed. Inclusion criteria were actively draining CD-PAF and initial treatment with IFX or ADA following CD-PAF diagnosis. The primary endpoints were perianal fistula response and remission at 6 and 12 months. Secondary endpoints included biologic persistence over time and dose escalation at 6 and 12 months. RESULTS: Among 151 patients included in the study, 92 received IFX and 59 received ADA as first line agents after CD-PAF diagnosis. At 6 months, the 64.9% of the IFX group and 34.8% of the ADA group demonstrated CD-PAF clinical improvement (p < 0.01). Univariate and multivariate analyses demonstrated significant differences among the IFX and ADA groups for clinical response at 6-months and 12-months (p = 0.002 and p = 0.042, respectively). There were no factors that predicted response, with the exception of concomitant immunomodulator affecting the 6-month clinical response (p = 0.021). Biologic persistence, characterized by Kaplan Meier methods, was significantly longer in the IFX group compared to the ADA group (Log-rank p = 0.01). CONCLUSION: IFX induction and maintenance is associated with higher rates of response and remission in CD-PAF healing as well as higher treatment persistence compared to ADA. Additionally, our study supports the use of concomitant immunomodulator therapy for CD-PAF healing and remission.

Background: The emergence of new SARS-CoV-2 variants calls for more data on SARS-CoV-2 mRNA vaccine response. Aims: We aimed to assess the response to a third mRNA vaccine dose against SARS-CoV-2 in inflammatory bowel disease (IBD) patients. Methods: This was a single-center, observational prospective study of IBD patients who received a third mRNA vaccine dose against SARS-CoV-2. Antibody titers were taken post-third-dose at one and three months using the Roche Elecsys anti-SARS-CoV-2-S enzyme immunoassay. Titers less than 0.8 units/mL were considered negative according to the manufactures. Titers between 0.8 units/mL and 250 units/mL were considered non-neutralizing. Titers greater than 250 units/mL were considered neutralizing. Results: Eighty-three patients were included, all of whom had detectable antibodies at 3 months post-third dose. A total of 89% showed neutralizing and 11% non-neutralizing titers. Participants with non-neutralizing titers were more likely to be on systemic corticosteroids (p = 0.04). Two participants seroconverted from negative to positive, whereas 86% with non-neutralizing titers boosted to neutralizing levels. Only one participant with neutralizing titers after a third dose had a decrease to a non-neutralizing level within 3 months. Conclusions: Our findings support the ongoing recommendations for additional doses in immunocompromised individuals. However, longitudinal studies with a greater-sized patient population are needed.

Patients with inflammatory bowel disease (IBD) are recommended to receive vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), regardless of their immunosuppression status. Immunosuppressive medications represent a mainstay of therapy in moderate to severe IBD; however, their impact on the SARS-CoV-2 vaccine response remains unclear. Studies thus far have shown that patients with IBD on various therapies had detectable antibody responses after standard vaccinations.1-5 To date, one study has examined the kinetics of antibody response at 3 months after vaccination in patients with IBD, but data beyond this time point are not yet available.6 The aim of this study was to assess anti-spike antibody response 6 months after completion of standard SARS-CoV-2 vaccination in patients with IBD. Secondarily, we observed antibody kinetics over 6 months in a subset of patients post-vaccination.

INTRODUCTION: The response to SARS-CoV-2 vaccination of patients with inflammatory bowel disease (IBD) on immune-modifying therapies requires further investigation because previous studies indicate that patients on immune therapy might have decreased antibody concentrations. METHODS: We present the antireceptor binding domain antibody response over a period of 3 months in 217 patients with IBD who completed standard 2-dose SARS-CoV-2 mRNA vaccine series. RESULTS: Almost all (98.6%) IBD vaccine recipients had a positive antireceptor binding domain antibody response at least 3 months after vaccination. Decreased antibody titers at 3 months were seen in a subset of patients on antitumor necrosis factor-alpha. Approximately 10% of the participants with high-titer antibodies at 1 month had a decrease to low-positive titers at 3 months, which was mostly observed in those on combination therapy and antitumor necrosis factor-alpha monotherapy. DISCUSSION: Larger longitudinal studies are required to define the response in IBD population and its clinical impact.

Inflammatory bowel disease is characterized by chronic inflammation of the gastrointestinal tract and is associated with high risks for complications, surgeries, and frequent hospitalizations. Approximately one in four inflammatory bowel disease patients are readmitted to the hospital within 90 days of discharge in the United States. Although existing literature showed a timely clinic appointment with gastroenterologists is a protective factor for disease flare-ups and hospitalizations, the follow-up appointments were found to be either lacking or significantly delayed. Further, evidence-based guidelines in timely inflammatory bowel disease care are lacking. Thus, this integrative review examined current literature to identify effective strategies for achieving timely clinic appointments with gastroenterologists in inflammatory bowel disease. A comprehensive search of three electronic databases (PubMed, Embase, and Cumulative Index of Nursing and Allied Health Literature [CINAHL] Plus) was conducted from January 2009 to September 2019 using the key terms: inflammatory bowel disease, ulcerative colitis, Crohn's disease, appointments, and time to appointment. Nine articles met the inclusion criteria. The main interventions for timely inflammatory bowel disease care included (i) clinic-wide scheduling protocols, (ii) a dedicated healthcare team, (iii) efficient referral process, (iv) appointment management based on disease acuity and severity, and (v) addressing shortage of inflammatory bowel disease clinicians. Further research is needed to quantify the magnitude of timely inflammatory bowel disease care interventions with controls and evaluate the efficacy with a head-to-head trial. Through timely referrals, evaluations, and treatments, these quality improvement endeavors will ultimately improve quality of care and contribute to reduction in preventable hospitalizations and associated healthcare costs from delayed outpatient inflammatory bowel disease care.

Approximately one in four patients with inflammatory bowel disease are readmitted within 90 days. To reduce hospitalizations, regular follow-up appointments with gastroenterologists are essential. However, the mean wait time for gastroenterology clinic appointments significantly exceeded the target goal of 14 days in North America. Based on literature review, we developed and implemented a new appointment scheduling protocol. The inclusion criteria were adult patients with inflammatory bowel disease who were recently hospitalized or newly referred to a gastroenterology clinic. At weeks 0 and 12, wait times were extrapolated from chart review, and patient satisfaction rates were collected via surveys. Patient demographics and outcome data were examined using descriptive statistics. A total of 16 patients were included. Following the intervention, the mean wait time decreased from 40.4 (SD = 31.9) to 21.9 days (SD = 11.4), but the change was statistically insignificant (p = .408). Poor response rates (47%) limited the interpretation of the patient satisfaction data. Despite the small sample size, our project was the first quality improvement initiative that implemented an evidence-based appointment scheduling protocol among adult patients with inflammatory bowel disease. Further studies are warranted with a larger sample size to better evaluate its efficacy in achieving timely outpatient gastroenterology care.

BACKGROUND: Immune checkpoint inhibitors (ICIs) may cause immune-related adverse events (irAEs). Methods to obtain real-time multidisciplinary input for irAEs that require subspecialist care are unknown. This study aimed to determine whether a virtual multidisciplinary immune-related toxicity (IR-tox) team of oncology and medicine subspecialists would be feasible to implement, be used by oncology providers, and identify patients for whom multidisciplinary input is sought. PATIENTS AND METHODS: Patients treated with ICIs and referred to the IR-tox team in August 2017 through March 2018 were identified. Feasibility was defined as receipt of electronic referrals and provision of recommendations within 24 hours of referral. Use was defined as the proportion of referring providers who used the team's recommendations, which was determined through a postpilot survey. Demographics and tumor, treatment, and referral data were collected. Patient features and irAE associations were analyzed. RESULTS: The IR-tox team was found to be feasible and used: 117 referrals from 102 patients were received in 8 months, all providers received recommendations within 24 hours, 100% of surveyed providers used the recommendations, and 74% changed patient management based on IR-tox team recommendations. Referrals were for suspected irAEs (n=106; 91%) and suitability to treat with ICIs (n=11; 10%). In referred patients, median age was 64 years, 54% were men, 13% had prior autoimmunity, and 46% received ICI combinations versus monotherapy (54%). The most commonly referred toxicities were pneumonitis (23%), arthritis (16%), and dermatitis (15%); 15% of patients had multisystem toxicities. Multiple referrals were more common in those treated with combination ICIs (odds ratio [OR], 6.0; P=.035) or with multisystem toxicities (OR, 8.1; P=.005). The IR-tox team provided a new multidisciplinary forum to assist providers in diagnosing and managing complex irAEs. This model identifies educational and service needs, and patients with irAEs for whom multidisciplinary care is most sought. CONCLUSIONS: A virtual multidisciplinary toxicity team for irAEs was a feasible and used service, and facilitated toxicity identification and management.

BACKGROUND: Inflammatory bowel disease (IBD), comprised of Crohn's disease (CD) and ulcerative colitis (UC), is characterized by chronic mucosal inflammation, frequent hospitalizations, adverse health economics, and compromised quality of life. Diet has been hypothesised to influence IBD activity. OBJECTIVES: To evaluate the efficacy and safety of dietary interventions on IBD outcomes. SEARCH METHODS: We searched the Cochrane IBD Group Specialized Register, CENTRAL, MEDLINE, Embase, Web of Science, Clinicaltrials.gov and the WHO ICTRP from inception to 31 January 2019. We also scanned reference lists of included studies, relevant reviews and guidelines. SELECTION CRITERIA: We included randomized controlled trials (RCTs) that compared the effects of dietary manipulations to other diets in participants with IBD. Studies that exclusively focused on enteral nutrition, oral nutrient supplementation, medical foods, probiotics, and parenteral nutrition were excluded. DATA COLLECTION AND ANALYSIS: Two review authors independently performed study selection, extracted data and assessed bias using the risk of bias tool. We conducted meta-analyses where possible using a random-effects model and calculated the risk ratio (RR) and corresponding 95% confidence interval (CI) for dichotomous outcomes. We assessed the certainty of evidence using GRADE. MAIN RESULTS: The review included 18 RCTs with 1878 participants. The studies assessed different dietary interventions for active CD (six studies), inactive CD (seven studies), active UC (one study) and inactive UC (four studies). Dietary interventions involved either the consumption of low amounts or complete exclusion of one or more food groups known to trigger IBD symptoms. There was limited scope for data pooling as the interventions and control diets were diverse. The studies were mostly inadequately powered. Fourteen studies were rated as high risk of bias. The other studies were rated as unclear risk of bias.The effect of high fiber, low refined carbohydrates, low microparticle diet, low calcium diet, symptoms-guided diet and highly restricted organic diet on clinical remission in active CD is uncertain. At 4 weeks, remission was induced in: 100% (4/4) of participants in the low refined carbohydrates diet group compared to 0% (0/3) of participants in the control group (RR 7.20, 95% CI 0.53 to 97.83; 7 participants; 1 study; very low certainty evidence). At 16 weeks, 44% (23/52) of participants in the low microparticle diet achieved clinical remission compared to 25% (13/51) of control-group participants (RR 3.13, 95% CI 0.22 to 43.84; 103 participants; 2 studies; I² = 73%; very low certainty evidence). Fifty per cent (16/32) of participants in the symptoms-guided diet group achieved clinical remission compared to 0% (0/19) of control group participants (RR 20.00, 95% CI 1.27 to 315.40; 51 participants ; 1 study; very low certainty evidence) (follow-up unclear). At 24 weeks, 50% (4/8) of participants in the highly restricted organic diet achieved clinical remission compared to 50% (5/10) of participants in the control group (RR 1.00, 95% CI 0.39 to 2.53; 18 participants; 1 study; very low certainty evidence). At 16 weeks, 37% (16/43) participants following a low calcium diet achieved clinical remission compared to 30% (12/40) in the control group (RR 1.24, 95% CI 0.67 to 2.29; 83 participants; 1 study; very low certainty evidence).The effect of low refined carbohydrate diets, symptoms-guided diets and low red processed meat diets on relapse in inactive CD is uncertain. At 12 to 24 months, 67% (176/264) of participants in low refined carbohydrate diet relapsed compared to 64% (193/303) in the control group (RR 1.04, 95% CI 0.87 to 1.25; 567 participants; 3 studies; I² = 35%; low certainty evidence). At 6 to 24 months, 48% (24/50) of participants in the symptoms-guided diet group relapsed compared to 83% (40/48) participants in the control diet (RR 0.53, 95% CI 0.28 to 1.01; 98 participants ; 2 studies; I² = 54%; low certainty evidence). At 48 weeks, 66% (63/96) of participants in the low red and processed meat diet group relapsed compared to 63% (75/118) of the control group (RR 1.03, 95% CI 0.85 to 1.26; 214 participants; 1 study; low certainty evidence). At 12 months, 0% (0/16) of participants on an exclusion diet comprised of low disaccharides / grains / saturated fats / red and processed meat experienced clinical relapse compared to 26% (10/38) of participants on a control group (RR 0.11, 95% CI 0.01 to 1.76; 54 participants; 1 study; very low certainty evidence).The effect of a symptoms-guided diet on clinical remission in active UC is uncertain. At six weeks, 36% (4/11) of symptoms-guided diet participants achieved remission compared to 0% (0/10) of usual diet participants (RR 8.25, 95% CI 0.50 to 136.33; 21 participants; 1 study; very low certainty evidence).The effect of the Alberta-based anti-inflammatory diet, the Carrageenan-free diet or milk-free diet on relapse rates in inactive UC is uncertain. At 6 months, 36% (5/14) of participants in the Alberta-based anti-inflammatory diet group relapsed compared to 29% (4/14) of participants in the control group (RR 1.25, 95% CI 0.42 to 3.70; 28 participants; 1 study; very low certainty evidence). Thirty per cent (3/10) of participants following the carrageenan-free diet for 12 months relapsed compared to 60% (3/5) of the participants in the control group (RR 0.50, 95% CI 0.15 to 1.64; 15 participants; 1 study; very low certainty evidence). At 12 months, 59% (23/39) of milk free diet participants relapsed compared to 68% (26/38) of control diet participants (RR 0.83, 95% CI 0.60 to 1.15; 77 participants; 2 studies; I² = 0%; low certainty evidence).None of the included studies reported on diet-related adverse events. AUTHORS' CONCLUSIONS: The effects of dietary interventions on CD and UC are uncertain. Thus no firm conclusions regarding the benefits and harms of dietary interventions in CD and UC can be drawn. There is need for consensus on the composition of dietary interventions in IBD and more RCTs are required to evaluate these interventions. Currently, there are at least five ongoing studies (estimated enrollment of 498 participants). This review will be updated when the results of these studies are available.

BACKGROUND: Creation of a J pouch is the gold standard surgical intervention in the treatment of chronic ulcerative colitis (UC). Pouchoscopy prior to ileostomy takedown is commonly performed. We describe the frequency, indication, and findings on pouchoscopy, and determine if pouchoscopy affects rates of complications after takedown. METHODS: All UC or indeterminate inflammatory bowel disease patients with a J pouch were retrospectively evaluated from January 1994 to December 2014. Cases were defined as having routine (asymptomatic) pouchoscopy after pouch creation but before ileostomy takedown. Controls were defined as having no pouchoscopy or pouchoscopy on the same day as that of takedown. RESULTS: The study included 178 patients (81.5% cases, 18.5% controls). Fifty two percent of pouchoscopies were reported as normal. Common abnormal endoscopy findings included stricture (35%), pouchitis (7%), and cuffitis (0.7%). Length of stay during takedown hospitalization was shorter for cases than controls (3 vs. 5 days; p = 0.001), but neither short- nor long-term complications were statistically different between cases and controls. Abnormalities on pouchoscopy were not predictive for short-term complications (p = 0.73) or long-term complications (p = 0.55). Routine pouchoscopy did not delay takedown surgery in any of the included patients. CONCLUSIONS: Routine pouchoscopy may not be necessary prior to ileostomy takedown; its greatest utility is in patients with suspected pouch complications.

BACKGROUND: Approximately 15-20% of ulcerative colitis patients and 20-40% of those with Crohn's disease experience extraintestinal manifestations (EIMs) of their inflammatory bowel disease (IBD). Clinicians who treat IBD must manage EIMs affecting multiple organs that variably correlate with intestinal disease activity. Vedolizumab is a monoclonal antibody for the treatment of IBD with a gut-selective mechanism of action. AIMS: This report evaluates whether vedolizumab is an effective treatment of EIMs, given its gut-specific mechanism of action. METHODS: We report 8 case studies of patients with various EIMs, including pyoderma gangrenosum, peripheral arthralgia/arthritis, axial arthropathies, erythema nodosum, and uveitis, who received vedolizumab therapy. RESULTS: Vedolizumab therapy was effective for pyoderma gangrenosum in ulcerative colitis, uveitis, erythema nodosum, polyarticular arthropathy, and ankylosing spondylitis/sacroiliitis but did not provide sustained benefit for the treatment of pyoderma gangrenosum in a patient with Crohn's disease. CONCLUSIONS: These cases demonstrate the potential of vedolizumab as a treatment of EIMs in patients with IBD.

BACKGROUND: Cigarette smoking is thought to increase the risk of Crohn's disease (CD) and exacerbate the disease course, with opposite roles in ulcerative colitis (UC). However, these findings are from Western populations, and the association between smoking and inflammatory bowel disease (IBD) has not been well studied in Asia. AIMS: We aimed to compare the prevalence of smoking at diagnosis between IBD cases and controls recruited in China, India, and the USA, and to investigate the impact of smoking on disease outcomes. METHODS: We recruited IBD cases and controls between 2014 and 2018. All participants completed a questionnaire about demographic characteristics, environmental risk factors and IBD history. RESULTS: We recruited 337 participants from China, 194 from India, and 645 from the USA. In China, CD cases were less likely than controls to be current smokers (adjusted odds ratio [95% CI] 0.4 [0.2-0.9]). There was no association between current or former smoking and CD in the USA. In China and the USA, UC cases were more likely to be former smokers than controls (China 14.6 [3.3-64.8]; USA 1.8 [1.0-3.3]). In India, both CD and UC had similar current smoking status to controls at diagnosis. Current smoking at diagnosis was significantly associated with greater use of immunosuppressants (4.4 [1.1-18.1]) in CD cases in China. CONCLUSIONS: We found heterogeneity in the associations of smoking and IBD risk and outcomes between China, India, and the USA. Further study with more adequate sample size and more uniform definition of smoking status is warranted.

OBJECTIVES: Early appendectomy is inversely associated with the development of UC. However, the impact of appendectomy on the clinical course of UC is controversial, generally favouring a milder disease course. We aim to describe the effect appendectomy has on the disease course of UC with focus on the timing of appendectomy in relation to UC diagnosis. DESIGN: Using the National Institute of Diabetes and Digestive and Kidney Diseases Inflammatory Bowel Disease Genetics Consortium database of patients with UC, the risk of colectomy was compared between patients who did and did not undergo appendectomy. In addition, we performed a meta-analysis of studies that examined the association between appendectomy and colectomy. RESULTS: 2980 patients with UC were initially included. 111 (4.4%) patients with UC had an appendectomy; of which 63 were performed prior to UC diagnosis and 48 after diagnosis. In multivariable analysis, appendectomy performed at any time was an independent risk factor for colectomy (OR 1.9, 95% CI 1.1 to 3.1), with appendectomy performed after UC diagnosis most strongly associated with colectomy (OR 2.2, 95% CI 1.1 to 4.5). An updated meta-analysis showed appendectomy performed either prior to or after UC diagnosis had no effect on colectomy rates. CONCLUSIONS: Appendectomy performed at any time in relation to UC diagnosis was not associated with a decrease in severity of disease. In fact, appendectomy after UC diagnosis may be associated with a higher risk of colectomy. These findings question the proposed use of appendectomy as treatment for UC.

BACKGROUND & AIMS: Little is known about the effects of biologic agents used to treat Crohn's disease (CD) on its long-term complications, such as short bowel syndrome and intestinal failure (SBS-IF). We evaluated trends in small bowel resections and health care utilization among patients with CD with and without SBS-IF. METHODS: We collected data on the National Inpatient Sample on 2,989,185 patients hospitalized with CD in the United States before the time period in which CD was treated with biologic agents (1993-1997) and after biologic therapy became widespread (1998-2014). We used Poisson and linear regression analyses to evaluate trends for small bowel resections and health care utilization among patients with CD with and without SBS-IF. Multivariable models were adjusted for age, sex, Charlson-Deyo comorbidity index, payer source, hospital size, region, and teaching status. RESULTS: The proportions of patients who underwent resection did not significantly change during the period before biologic therapy (121.8 per 1000 hospitalizations in 1993 to 110.1 per 1000 hospitalizations in 1997; P trend =.14) but decreased significantly during the period after biologic therapy began (99.0 per 1000 hospitalizations in 1998 to 64.6 per 1000 hospitalizations in 2014; P trend < .01). However, among patients with SBS-IF, similar proportions of patients underwent resection during the period before biologic therapy (0.7 per 1000 hospitalizations in 1993 to 0.7 per 1000 hospitalizations in 1997; P trend = .92) and during the period after biologic therapy (0.6 per 1000 hospitalizations in 1998 to 0.7 per 1000 hospitalizations in 2014; P trend = .06). Rates of hospitalization for patients with SBS-IF increased from 16.5 per 1000 hospitalizations in 1998 to 19.5 per 1000 hospitalizations in 2014 (P trend < .01). SBS-IF hospitalizations were associated with longer lengths of stay (P < .01) and greater total charges (P < .01). CONCLUSIONS: In a study of the United States population, we found that the use of biologic agents to treat CD reduced the proportion of patients undergoing resection, but not among patients with SBS-IF. These findings indicate that biologic agents reduce some but not all features of CD. Studies are needed to identify patients at risk for SBS-IF, prevent and treat this complication, and identify new treatments.

BACKGROUND: It is unclear whether intensive surveillance protocols have resulted in a decreased incidence of colorectal cancer (CRC) in inflammatory bowel disease (IBD). AIMS: To determine the prevalence and characteristics of IBD associated high-grade dysplasia (HGD) or CRC that was undetected on prior colonoscopy. METHODS: This is a single-center, retrospective study from 1994 to 2013. All participants had a confirmed IBD diagnosis and underwent a colectomy with either HGD or CRC found in the colectomy specimen.The undetected group had no HGD or CRC on prior colonoscopies. The detected group had HGD or CRC identified on previous biopsies. RESULTS: Of 70 participants, with ulcerative colitis (UC) (n = 47), Crohn's disease (CD) (n = 21), and indeterminate colitis (n = 2), 29% (n = 20) had undetected HGD/CRC at colectomy (15 HGD and 5 CRC). In the undetected group, 75% had prior LGD, 15% had indefinite dysplasia, and 10% had no dysplasia (HGD was found in colonic strictures). Patients in the undetected group were more likely to have pancolitis (55 vs. 20%) and multifocal dysplasia (35 vs. 8%). The undetected group was less likely to have CRC at colectomy (25 vs. 62%). There was a trend toward right-sided HGD/CRC at colectomy (40 vs. 20%; p = 0.08). In addition, 84% of the lesions found in the rectum at colectomy were not seen on prior colonoscopy in the undetected group. CONCLUSIONS: The prevalence of previously undetected HGD/CRC in IBD found at colectomy was 29%. The high proportion of undetected rectal and right-sided HGD/CRC suggests that these areas may need greater attention during surveillance.
