La pandemia por COVID-19 ha supuesto un reto para los países y sus profesionales sanitarios. La entrada viral en el hospedador a través del receptor ACE-2 y una activación excesiva del sistema inmunológico son claves para comprender tanto la incidencia como la gravedad de la enfermedad. La enfermedad inflamatoria intestinal (EII) representa una condición especial asociada con una respuesta descontrolada del sistema inmunológico a agentes externos. Los tratamientos para la EII se han asociado con un mayor riesgo de infecciones bacterianas y virales. Esto ha planteado la cuestión de una posible mayor incidencia y gravedad de la infección por COVID-19 en pacientes con EII. A lo largo de este año se han publicado varios artículos que tratan de responder esa cuestión. La vacunación contra la COVID-19 ofrece una gran promesa para controlar la infección en pacientes con EII. Según la evidencia actual, los pacientes con EII no tienen mayor incidencia de COVID-19 ni peor evolución de la enfermedad en comparación con la población general. La edad avanzada y la presencia de un mayor número de comorbilidades se han asociado con peores resultados. Los corticosteroides están asociados con un mayor riesgo de infección por COVID-19, una mayor tasa de hospitalizaciones y un mayor riesgo de COVID-19 grave. La mesalazina/sulfasalazina y las tiopurinas presentan un posible aumento del riesgo de COVID-19 grave, aunque se requieren más estudios para demostrar esta asociación. Dentro de los fármacos biológicos, los anti-TNF pueden tener un posible efecto protector. Los anti-IL-12/23, anti-integrinas y tofacitinib presentan resultados comparables con anti-TNF. Se recomienda mantener el tratamiento con agentes biológicos. En base a la eficacia, las recomendaciones de los expertos y la ausencia de otra evidencia, se recomienda la vacunación de pacientes con EII.

Endoscopic balloon dilation (EBD) is the established endoscopic treatment for short strictures in Crohn's disease. Fully covered self-expandable metal stents (FCSEMS) have been used for endoscopic treatment of patients for whom EBD was unsuccessful. We aimed to determine the efficacy and safety of the two endoscopic treatments in patients with Crohn's disease with stenosis and compare the mean cost of both treatments.This multicentre, open-label, randomised trial was done in 19 tertiary and secondary hospitals in Spain. Patients with Crohn's disease with obstructive symptoms and predominantly fibrotic strictures of less than 10 cm in length were eligible for inclusion. We excluded patients with stenosis treated with SEMS or EBD in the previous year and stenosis not accessible to a colonoscope. Patients were randomly assigned (1:1) to receive either EBD (EBD group) or FCSEMS (FCSEMS group) using a digital en-block randomisation system (block size of four). In the EBD group, dilation was done with a CRE Boston Scientific (Marlborough, MA, USA) pneumatic balloon with the diameter set at the discretion of the endoscopist; a maximum of two sessions of dilation were allowed with a minimum interval of 15-30 days between them. In the FCSEMS group, a 20 mm diameter Taewoong (Gimpo-si, South Korea) fully covered metal stent was placed; stent length was set at the discretion of the endoscopist. The primary outcome was to assess the efficacy of the endoscopic treatment, defined by the proportion of patients free of a new therapeutic intervention (EBD, FCSEMS, or surgery) due to symptomatic recurrence at 1 year of follow-up. Patients were analysed according to the intention-to-treat principle. Adverse events were recorded for all the patients; events were considered associated to be with the procedure when a causal association was possible, probable, or definite. This trial is registered with ClinicalTrials.gov, NCT02395354.From Aug 28, 2013, to Oct 9, 2017, we assessed the eligibility of 99 patients, of whom 19 (19%) patients were excluded. Thus, 80 (81%) patients were randomly assigned to treatment: 39 (49%) patients to the FCSEMS group and 41 (51%) patients to the EBD group. 33 (80%) of 41 patients in the EBD group and 20 (51%) of 39 patients in the FCSEMS group were free of a new therapeutic intervention at 1 year (odds ratio [OR] 3·9 [95% CI 1·4-10·6]; p=0·0061). Two (3%) of 80 patients had severe adverse events (one [2%] patient in the EBD group and one [3%] patient in the FCSEMS group); both patients had perforations.EBD is more effective than FCSEMS for Crohn's disease strictures, with a good safety profile for both treatments.Spanish National Institute of Health, Foundation of Spanish Society of Digestive Endoscopy, Catalan Society of Gastroenterology, and Taweoong.

Loss-of-response and adverse events (AE) to biologics have been linked to HLA-DQA1*05 allele. However, the clinical factors or biologic used may influence treatment duration. Our objective was to evaluate the influence of clinical and therapeutic factors, along with HLA, in biological treatment discontinuation.A retrospective study of consecutive IBD patients treated with biologics between 2007 and 2011 was performed. Main outcome was treatment discontinuation due to primary non-response (PNR), secondary loss of response (SLR) or AE. HLA-DQA1 genotyping was done in all patients. Regression analyses were used to assess risk factors of treatment discontinuation.One hundred fifty patients (61% male) with 312 biologic treatments were included. 147 (47%) were discontinued with a cumulative probability of 30%, 41% and 56% at 1, 2 and 5 years. The use of infliximab (p=0.006) and articular manifestations (p0.05) were associated with treatment discontinuation. Considering cause of withdrawal, Ulcerative Colitis (UC) had a higher proportion of PNR (HR=4.99; 95% CI=1.71-14.63; p=0.003), SLR was higher if biologics had been indicated due to disease flare (HR=2.32; 95% CI=1.05-5.09; p=0.037) while AE were greater with infliximab (HR=2.46; 95% CI=1.48-4.08; p0.001) or spondylitis (HR=2.46; 95% CI=1.78-6.89; p0.001). According to the biological drug, HLA-DQA1*05 with adalimumab showed more SLR in cases with Crohn's disease (HR=3.49; 95% CI=1.39-8,78; p=0.008) or without concomitant immunomodulator (HR=2.8; 95% CI=1.1-6.93; p=0.026).HLA-DQ A1*05 was relevant in SLR of IBD patients treated with adalimumab without immunosupression. In patients treated with other biologics, clinical factors were more important for treatment interruption, mainly extensive UC or extraintestinal manifestations and having indicated the biologic for flare.

Therefore, the aim of this study was to assess these differences between infected and noninfected patients with IBD. (2) This nationwide case−control study evaluated patients with inflammatory bowel disease with COVID-19 (cases) and without COVID-19 (controls) during the period March−July 2020 included in the ENEIDA of GETECCU. (3) A total of 496 cases and 964 controls from 73 Spanish centres were included. No differences were found in the basal characteristics between cases and controls. Cases had higher comorbidity Charlson scores (24% vs. 19%; p = 0.02) and occupational risk (28% vs. 10.5%; p < 0.0001) more frequently than did controls. Lockdown was the only protective measure against COVID-19 (50% vs. 70%; p < 0.0001). No differences were found in the use of systemic steroids, immunosuppressants or biologics between cases and controls. Cases were more often treated with 5-aminosalicylates (42% vs. 34%; p = 0.003). Having a moderate Charlson score (OR: 2.7; 95%CI: 1.3−5.9), occupational risk (OR: 2.9; 95%CI: 1.8−4.4) and the use of 5-aminosalicylates (OR: 1.7; 95%CI: 1.2−2.5) were factors for COVID-19. The strict lockdown was the only protective factor (OR: 0.1; 95%CI: 0.09−0.2). (4) Comorbidities and occupational exposure are the most relevant factors for COVID-19 in patients with IBD. The risk of COVID-19 seems not to be increased by immunosuppressants or biologics, with a potential effect of 5-aminosalicylates, which should be investigated further and interpreted with caution.

BACKGROUND: Knowing patients' ulcerative colitis history is essential to selecting the appropriate therapy according to risk stratification. OBJECTIVE: To evaluate and identify predictive factors of non-response to aminosalicylates judged as the need for a step-up approach over time. METHODS: A case-control study of ulcerative colitis patients treated with aminosalicylates after the diagnosis of disease flare included in the ENEIDA single-centre registry from 1997 to 2017. Long-term treatment maintenance with aminosalicylates and higher therapeutic requirements were recorded. The cumulative incidence of treatment escalation was estimated using Kaplan-Meier curves and compared by the log-rank test. Cox regression analysis was performed to identify predictive factors of treatment with immunomodulators, biological agents or surgery. RESULTS: A total of 457 patients were included, of whom 28% (n = 126) were non-responders to aminosalicylates. The cumulative probability for a step-up approach within 20 years of follow up was 35%, mainly due to steroid-dependent colitis. Risk factors for treatment escalation were age ≤27 years (hazard ratio 2.31, 95% confidence interval 1.36–3.92), extensive colitis (hazard ratio 1.65, 95% confidence interval 1.04–2.60), Mayo endoscopic subscore ≥2 (hazard ratio 1.45, 95% confidence interval 1.02–2.06) and extraintestinal manifestations (hazard ratio 2.04, 95% confidence interval 1.03–4.05). CONCLUSIONS: Aminosalicylates represent an effective maintenance therapy. Younger age, extensive colitis, endoscopic disease severity and extraintestinal manifestations are risk factors for higher therapeutic requirements.

Introduction Thiopurines are used as maintenance therapy in patients with ulcerative colitis (UC). There are contradictory results regarding the relationship between adherence to treatment and risk of relapse. Objectives To quantify and evaluate the trends in thiopurines prescription rates, and to determine the impact and risk factors of non-adherence. Methods Analytical, observational and retrospective study of UC patients, on thiopurines, included in the ENEIDA single-center registry from October 2017 to October 2019. We included adult patients under clinical remission at the beginning of the study on thiopurines maintenance treatment for at least 6 months before recruitment. Adherence was evaluated with an electronic pharmaceutical prescription system. Adherence was considered when 80% or more of the prescribed medication was dispensed at the pharmacy. Kaplan-Meier curves and a regression model were used to examine year-to-year treatment dispensation and identify factors associated to non-adherence. Results A total of 41 patients were included, of whom 71% were males with a mean age of 44 (14) and 26.8% were concomitantly managed with biological therapy. Overall, 22% were non-adherent to thiopurines. No predictive factors of non-adherence were identified. Adherence rate did not correlate with disease activity for two years follow-up (OR 1.6; 95CI =0.3-9.1). Left-sided colitis and concomitant biological treatment were related with disease relapses (p ≤0.01). Conclusion The adherence to thiopurines in UC patients is high (78%). Non-adherence is not related to clinical or pharmacological factors. Adherence rate was not associated with disease activity.

ObjectiveTo evaluate the impact of comorbidities and extraintestinal manifestations of inflammatory bowel disease on the response of patients with inflammatory bowel disease to antitumour necrosis factor alpha (anti-TNFα) therapy.DesignData from 310 patients (194 with Crohn’s disease and 116 with ulcerative colitis) treated consecutively with the first anti-TNFα in 24 Spanish hospitals were retrospectively analysed. Univariate and multivariate logistic regression analyses were performed to assess the associations between inflammatory bowel disease comorbidities and extraintestinal manifestations with anti-TNFα treatment outcomes. Key clinical features, such as type of inflammatory bowel disease and concomitant treatments, were included as fixed factors in the model.ResultsMultivariate logistic regression analyses (OR, 95% CI) showed that chronic obstructive pulmonary disease (2.67, 1.33 to 5.35) and hepato-pancreato-biliary diseases (1.87, 1.48 to 2.36) were significantly associated with primary non-response to anti-TNFα, as was the use of corticosteroids and the type of inflammatory bowel disease (ulcerative colitis vs Crohn’s disease). It was also found that myocardial infarction (3.30, 1.48 to 7.35) and skin disease (2.73, 1.42 to 5.25) were significantly associated with loss of response, along with the use of corticosteroids and the type of inflammatory bowel disease (ulcerative colitis vs Crohn’s disease).ConclusionsOur results suggest that the presence of some comorbidities in patients with inflammatory bowel disease, such as chronic obstructive pulmonary disease and myocardial infarction, and of certain extraintestinal manifestations of inflammatory bowel disease, such as hepato-pancreato-biliary conditions and skin diseases, appear to be related to failure to anti-TNFα treatment. Therefore, their presence should be considered when choosing a treatment.Trial registration numberNCT02861118.

Golimumab has demonstrated its long-term efficacy and safety in ulcerative colitis in clinical trials, but no data of long-term persistence has been published from real world. To estimate long-term persistence of golimumab, as well as factors associated with longer persistence, in patients with ulcerative colitis in real life. Observational multicentre study including adult patients with ulcerative colitis treated with golimumab and with at least twelve months of follow-up. We included 190 patients, 105 (55.26%) naive to anti-TNF, with mean disease duration of 9.32 ± 8.09 years. Probability of persistence was 63%, 46%, 39% and 27% at 1, 2, 3 and 4 years, respectively. Persistence was lower in patients with primary failure to previous anti-TNF. Eighty-two (43.16%) patients needed dose intensification during follow-up, with a mean time until intensification of 8.03 ± 8.64 months. Dose intensification and lower disease duration predicted higher persistence with golimumab (p = 0.037 and p = 0.008, respectively). During a follow-up of 17.25 ± 15.83 months, 32 (16.5%) patients needed hospitalisation and 11 (6%) underwent colectomy. No unexpected adverse events were reported. Golimumab has demonstrated good persistence and safety profile for long treatment in ulcerative colitis patients.

The impact of COVID-19 on inflammatory bowel disease (IBD) patients under pharmacological immunosuppression is still not clearly understood. We investigated the incidence of COVID-19 and the impact of immunosuppression and containment measures on the risk of SARS-CoV-2 infection in a large IBD cohort, from a multicenter cohort from 21st of February to 30th of June, 2020. Ninety-seven patients with IBD (43 UC, 53 CD, one unclassified IBD) and concomitant COVID-19 over a total of 23,879 patients with IBD were enrolled in the study. The cumulative incidence of SARS-CoV-2 infection in patients with IBD vs. the general population was 0.406% and 0.402% cases, respectively. Twenty-three patients (24%) were hospitalized, 21 (22%) had pneumonia, four (4%) were admitted to the Intensive Care Unit, and one patient died. Lethality in our cohort was 1% compared to 9% in the general population. At multivariable analysis, age &gt, 65 years was associated with increased risk of pneumonia and hospitalization (OR 11.6, 95% CI 2.18&ndash, 62.60, OR 5.1, 95% CI 1.10&ndash, 23.86, respectively), treatment with corticosteroids increased the risk of hospitalization (OR 7.6, 95% CI 1.48&ndash, 40.05), whereas monoclonal antibodies were associated with reduced risk of pneumonia and hospitalization (OR 0.1, 95% CI 0.04&ndash, 0.52, OR 0.3, 95% CI 0.10&ndash, 0.90, respectively). The risk of COVID-19 in patients with IBD is similar to the general population. National lockdown was effective in preventing infection in our cohort. Advanced age and treatment with corticosteroids impacted negatively on the outcome of COVID-19, whereas monoclonal antibodies did not seem to have a detrimental effect.

Recognizing patients with inflammatory bowel disease who are prone to infection would enable the adjustment of the type and intensity of immunosuppressive treatment. The aim of this study was to identify a clinical profile of risk for infections in IBD patients, based on the interaction of immunosuppressive treatment with factors inherent to the patient. A case-control study was performed among patients older than 18 years. Patients with any significant infection (any kind of severe or recurrent infection according to standard clinical criteria or a critical enough infection according to the patient) were defined as cases. Both cases and controls were randomly selected in a 1:3 ratio. All the period from diagnosis to the end of recruitment (June 2016) was analyzed. Risk factors for infection were identified by logistic regression analysis; the strength of association was reported by odds ratio (OR) with 95% confidence interval (95%CI). A total of 112 cases and 270 controls were included. The independent risk factors for significant infection are the number of immunosuppressants (one drug: OR 1.28, 95% CI 0.53–3.11, two drugs: OR 2.37, 95% CI 1.01–5,56, and three drugs: OR 5.84, 95% CI 1.57–21.72), body mass index (OR 1.08; 95 %CI 1,01–1,16), the degree of comorbidity (OR 1.52; 95% CI 1.04–2.21), and the intensity of inflammatory activity (OR 1.43; 95% CI 1.19–1.71). Regardless of immunosuppression, several patient factors such as comorbidity, body mass index, or the inflammatory activity of the disease determine the individual risk of infectious complications and should be considered for an adequate risk assessment.

Resumen La enfermedad de Crohn es una enfermedad inflamatoria intestinal cronica de etiologia desconocida asociada a una respuesta inmunologica alterada que cursa con periodos de actividad y remision. Puede afectar a cualquier tramo del tracto gastrointestinal, desde la boca hasta el ano, principalmente de forma transmural y parcheada. Los sintomas mas frecuentes son el dolor abdominal y la diarrea, pudiendo afectar gravemente la calidad de vida de los pacientes. El aumento de su incidencia y prevalencia en nuestro medio ha condicionado un creciente impacto en la practica clinica habitual asi como un rapido desarrollo de tecnicas diagnosticas y terapeuticas. Es por ello que tanto medicos de familia como especialistas deben estar familiarizados con el manejo de la enfermedad.

Resumen Objetivos Establecer recomendaciones para el manejo de los aspectos psicologicos de los pacientes con enfermedad inflamatoria intestinal (EII). Metodos Se llevo a cabo una reunion con un grupo de expertos en EII formado por medicos, psicologos, enfermeras y representantes de pacientes. Se presentaron resultados de: 1) un grupo focal previo, 2) encuestas a medicos y pacientes y 3) una revision sistematica sobre instrumentos de cribado de ansiedad y depresion. Se realizo una discusion guiada sobre los aspectos psicologicos y emocionales mas importantes en EII, los criterios de derivacion apropiados y situaciones a evitar. Se selecciono el instrumento validado mas aplicable a la practica clinica. Se diseno un documento con recomendaciones, asi como una encuesta Delphi. La encuesta fue enviada al grupo y a un comite cientifico seleccionado del grupo GETECCU, con el objetivo de establecer el grado de apoyo a las recomendaciones establecidas. Resultados Se establecieron 15 recomendaciones, pertenecientes a 3 procesos clave: 1) que pasos dar para identificar problemas psicologicos en consulta de EII, 2) criterios de derivacion a profesionales de la salud mental y 3) abordaje de los problemas psicologicos. Conclusiones Se deben facilitar recursos a los profesionales sanitarios para que puedan tratar estos aspectos en consulta, identificar los trastornos que puedan afectar el curso de la enfermedad o su impacto en la vida del paciente, para ser tratados y seguidos por el profesional mas adecuado. Estas recomendaciones pueden servir de base para el rediseno de los servicios o procesos de EII y como justificacion para la formacion del personal sanitario.

Aim To determine the genetic predisposition to celiac disease (CeD) in inflammatory bowel disease (IBD) patients by quantifying the frequency of CeD-related human leucocyte antigen (HLA) (HLA-CeD: HLA-DQ2 and -DQ8) in IBD patients globally, by type of IBD and gender, and by calculating the protective/risk contribution of these haplotypes in the development of the IBD disease. Methods We conducted a prospective study with IBD patients from our Unit. Clinical information was gathered and blood was tested for HLA-CeD. The control group was made up of unrelated Valencian organ donors. Results 1034 subjects were analyzed: 457 IBD [207 ulcerative coliti (UC) and 250 Crohn's disease (CD)] patients and 577 healthy controls. 39% of the controls and 34% of the patients had HLA-CeD (P = 0.0852). HLA-DQ2 was less frequent in UC patients (P = 0.0287), and HLA-DQ8 in CD (P = 0.0217). In women with UC, the frequency of DQ2.5cis (DQB1*02:01-DQA1*05:01) was reduced ≥ 50% [P = 0.0344; preventive fraction (PF) = 13%]. PFs (7%-14%) were obtained with all HLA-CeD haplotypes. HLA DQB1*02:02-DQA1*02:01 (HLA-DQ2.2) was more frequent in CD patients with respect to controls (P = 0.001) and UC patients (etiological fraction = 15%). Conclusion HLA-CeD is not more frequent in IBD patients, with an even lower frequency of HLA-DQ2 and -DQ8 in UC and CD respectively. HLA-DQ2.5 confers protection from the development of UC, especially in women, and HLA-DQ8 does so for the appearance of CD. HLA-DQ2.2 is present in 34% of the CD patients and may constitute a genetic risk factor for CD development.

Resumen En el ano 2016, se han publicado numerosos articulos de calidad sobre la enfermedad de Crohn (EC) y la colitis ulcerosa (CU). La importancia de la dieta o de los germenes en la enfermedad inflamatoria intestinal (EII), la repercusion de la EII en la calidad de vida, el papel de la calprotectina o la posibilidad de usar el PET en el seguimiento de la EII son algunos de los temas a destacar. El tratamiento ha sido foco de numerosos ensayos, consolidando el infliximab (sugiriendo niveles en la semana 2), el adalimumab y el golimumab, como tratamientos de primera linea, apoyando el uso de ustekinumab en EC, y dejando el metotrexato como ultimo recurso en la CU, salvo en artropatia. Por otro lado, se han sugerido alternativas como celulas madre, biosimilares y nuevos farmacos.

Aim: To evaluate outcomes of early dose optimization of golimumab in ulcerative colitis (UC) patients with inadequate response to golimumab induction treatment.Methods: This observational, multicenter, cohort study included patients with moderate-to-severe active UC and with inadequate response to subcutaneous golimumab induction doses, in whom weight-based golimumab maintenance dose (European labeling) of 50mg every 4weeks (q4wk) was optimized before week 14 to 100mg q4wk. At week 14, we assessed clinical response and remission using the partial Mayo score. In the long term we evaluate the cumulative probabilities of golimumab failure-free survival and colectomy-free survival.Results: A total of 209 patients who received golimumab induction doses were eligible. Of these, 151 patients (72.2%) weighing less than 80kg were assigned to a golimumab maintenance dose of 50mg q4wk. Twenty-four patients (15.9% [12.5% overall]), in whom scheduled doses of 50mg q4wk were optimized to 100mg q4wk before week 14, compose the study population. At week 14, 16 patients (66.7%, 95% CI 45.7-87.6) had clinical response, of these 12 were corticosteroid free. Four patients (16.7%) achieved corticosteroid-free remission. After a median follow-up of 12months (IQR 10-22), 13 patients (54.2%) maintained clinical benefit. Thirteen of 16 patients (81.2%) with clinical response at week 14 maintained clinical benefit at last follow-up. All patients avoided colectomy. In none of the patients was golimumab dose de-escalated. There were no adverse events leading to golimumab withdrawal.Conclusion: Early optimization of golimumab dose induces clinical response at week 14 in two thirds of UC patients and leads to long-term clinical benefit in over half of patients.

BackgroundThe benefits of immunosuppressants for sustaining remission and preventing flares of IBD are well known. However, optimal timing for withdrawal has not been determined.AimsThe objective of this study was to calculate the risk of relapse and predictors after withdrawal of azathioprine (AZA) monotherapy in patients who sustain deep remission.MethodsThis was a multicenter observational study of patients with IBD in remission whose immunosuppressant had been withdrawn. We recorded demographic variables, disease data, laboratory values, and the results of imaging tests performed at withdrawal and, in patients who relapsed, time to relapse and the efficacy of reintroducing the drug.ResultsNinety-five patients were included (35 UC and 60 CD). The mean duration of AZA treatment was 87 and 77months for UC and CD, respectively. Endoscopic remission was evaluated in 23 patients with UC and 35 with CD. After AZA withdrawal, 91% patients with UC and 67% with CD received high doses of salicylates. A total of 26 patients relapsed. The cumulative relapse rate at 5years was 46% for CD and UC. AZA was reintroduced in 19 patients, of whom 14 responded. Predictors of relapse were corticosteroid dependence, early introduction of AZA (CD), and late introduction of AZA (UC).ConclusionsAlmost half of the patients in whom AZA was withdrawn were in remission at 5years. The candidates for withdrawal could be better identified based on corticosteroid dependence, previous surgery, timing of initiation, and indication for AZA.

Background Treatment paradigms for Crohn's disease with perianal fistulae (CD-pAF) are evolving. Aims To study the impact of multimodality treatment in CD-pAF on recurrence rates and the need for re-interventions and to identify predictive factors for these outcomes. Methods This was a multinational multicentre retrospective cohort study. Multimodality approach was defined as using a combination of medical treatments (anti-TNFs ± immunomodulators ± antibiotics) along with surgical approach (examination under anaesthesia (EUA) ± seton drainage) at diagnosis of CD-pAF. Univariable and multivariable analyses were performed for variables indicative of the need for reintervention. Results A total of 253 patients were included. 65% of patients received multimodality approach. Multimodality treatment resulted in complete fistula healing in 52% of patients. Re-intervention was needed in 27% of patients with simple and in 40.3% of those with complex fistula. On multivariable analysis multimodality treatment (OR: 0.35, 95% CI: 0.17-0.57, P = 0.001), seton removal (OR: 0.090, 95% CI: 0.027-0.30, P = 0.0001, therapy with infliximab (OR: 0.19, 95% CI: 0.06-0.64, P = 0.007), and therapy with adalimumab (OR: 0.12, "95% CI: 0.026-0.56, P = 0.007) were predictive of avoiding repeat surgery. Proctitis (OR: 3.76, 95% CI: 1.09-12.96, P = 0.03) was predictive of the need for radical surgery (proctectomy, diverting stoma) while multimodality treatment reduced the need for radical surgery (OR: 0.21, 95% CI: 0.05-0.81, P = 0.02). Conclusions Multimodality treatment, anti-TNFs use, and removal of setons after multimodality treatment can result in improved outcomes in CD patients with perianal fistulae and reduce the need for repeat surgery and radical surgery.

Introduction: The fastest growing segment of our population is that of people above 70 years of age. Elderly patients with IBD exhibit several specific problems. Our objective was to evaluate the clinical course, the side effects of the treatments and the need for surgery of elderly patients, regardless of the age of onset.Materials and Methods: This was a cross-sectional study wherein retrospective data were collected from multiple centers from seven hospitals within the Valencia metropolitan area. Data were collected on patients older than 70y with inflammatory bowel disease.Results: We identified a total of 331 patients older than 70 years of age (5.3% of patients monitored at our centers). The mean age at the time of the study was 77.34y (5.39). Mesalamine were the most frequently used medications. Corticosteroids were used in 66% of the patients. However, the use of corticosteroids and biologics was less probable in older patients (OR 0.96, p=.06). The longer the disease progressed, the more immunosuppressive medications were used (OR 1.3, p=.052). Neoplasms appeared in 41 patients (13%). Of the 36 patients with tumors that appeared after the onset of the disease, 20 patients had not been treated with immunomodulators or biologics.Conclusions: Mesalamine was the most frequently used medication. There is no increased risk of tumors regarding the medications used. The use of immunosuppressive medications is more prevalent with longer disease progression times, although with a high rate of adverse events.

AIM To determine the genetic predisposition to celiac disease (CeD) in inflammatory bowel disease (IBD) patients by quantifying the frequency of CeD-related human leucocyte antigen (HLA) (HLA-CeD: HLA-DQ2 and -DQ8) in IBD patients globally, by type of IBD and gender, and by calculating the protective/risk contribution of these haplotypes in the development of the IBD disease. METHODS We conducted a prospective study with IBD patients from our Unit. Clinical information was gathered and blood was tested for HLA-CeD. The control group was made up of unrelated Valencian organ donors. RESULTS 1034 subjects were analyzed: 457 IBD [207 ulcerative coliti (UC) and 250 Crohn’s disease (CD)] patients and 577 healthy controls. 39% of the controls and 34% of the patients had HLA-CeD (P = 0.0852). HLA-DQ2 was less frequent in UC patients (P = 0.0287), and HLA-DQ8 in CD (P = 0.0217). In women with UC, the frequency of DQ2.5cis (DQB1*02:01-DQA1*05:01) was reduced ≥ 50% [P = 0.0344; preventive fraction (PF) = 13%]. PFs (7%-14%) were obtained with all HLA-CeD haplotypes. HLA DQB1*02:02-DQA1*02:01 (HLA-DQ2.2) was more frequent in CD patients with respect to controls (P = 0.001) and UC patients (etiological fraction = 15%). CONCLUSION HLA-CeD is not more frequent in IBD patients, with an even lower frequency of HLA-DQ2 and -DQ8 in UC and CD respectively. HLA-DQ2.5 confers protection from the development of UC, especially in women, and HLA-DQ8 does so for the appearance of CD. HLA-DQ2.2 is present in 34% of the CD patients and may constitute a genetic risk factor for CD development.

Crohn’s disease is one of the two commonly seen inflammatory bowel diseases. As opposed to ulcerative colitis, which only directly affects the colon and rectum, Crohn’s disease can affect any part of the intestinal tract. It can also involve the full thickness of the bowel wall, which accounts for many of the complications seen with the disease. Surgery is not curative but is reserved for the treatment of complications that are refractory to medical management. The etiology is unknown but it is increasingly clear that most patients have a genetic predisposition, though what purported environmental triggers are involved is less clear. Medical therapy has improved significantly, especially with the development of infliximab and adalimumab, but the prevalence of the disease is increasing, more patients are being identified at a younger age, and many still develop complications that require surgical intervention.

To establish recommendations for the management of psychological problems affecting patients with inflammatory bowel disease (IBD).A meeting of a group of IBD experts made up of doctors, psychologists, nurses and patient representatives was held. The following were presented: 1) Results of a previous focal group, 2) Results of doctor and patient surveys, 3) Results of a systematic review of tools for detecting anxiety and depression. A guided discussion was then held about the most important psychological and emotional problems associated with IBD, appropriate referral criteria and situations to be avoided. The validated instrument most applicable to clinical practice was selected. A recommendations document and a Delphi survey were designed. The survey was sent to the group and to a scientific committee of the GETECCU group in order to establish the level of agreement with these recommendations.Fifteen recommendations were established linked to 3 key processes: 1) What steps should be taken to identify psychological problems at an IBD appointment; 2) What are the criteria for referring patients to a mental health specialist; 3) How to approach psychological problems.Resources should be made available to healthcare professionals so that they can treat these problems during consultations, identify the disorders which could affect the clinical course of the disease and determine their impact on the patient's life in order that these can be treated and followed up by the most suitable professional. These recommendations could serve as a basis for redesigning IBD services or processes and as justification for the training of healthcare personnel.

Several studies demonstrate an increased prevalence and concordance of inflammatory bowel disease among the relatives of patients. Other studies suggest that genetic influence is over-estimated. The aims of this study are to evaluate the phenotypic expression and the treatment requirements in familial inflammatory bowel disease, to study the relationship between number of relatives and degree of kinship with disease severity and to quantify the impact of family aggregation compared to other environmental factors. Observational analytical study of 1211 patients followed in our unit. We analyzed, according to the existence of familial association, number and degree of consanguinity, the phenotypic expression, complications, extraintestinal manifestations, treatment requirements, and mortality. A multivariable analysis considering smoking habits and non-steroidal-anti-inflammatory drugs was performed. 14.2% of patients had relatives affected. Median age at diagnosis tended to be lower in the familial group, 32 vs 29, p = 0.07. In familial ulcerative colitis, there was a higher proportion of extraintestinal manifestations: peripheral arthropathy (OR = 2.3, p = 0.015) and erythema nodosum (OR = 7.6, p = 0.001). In familial Crohn’s disease, there were higher treatment requirements: immunomodulators (OR = 1.8, p = 0.029); biologics (OR = 1.9, p = 0.011); and surgery (OR = 1.7, p = 0.044). The abdominal abscess increased with the number of relatives affected: 5.1% (sporadic), 7.0% (one), and 14.3% (two or more), p=0.039. These associations were maintained in the multivariate analysis. Familial aggregation is considered a risk factor for more aggressive disease and higher treatment requirements, a tendency for earlier onset, more abdominal abscess, and extraintestinal manifestations, remaining a risk factor analyzing the influence of some environmental factors.

Inflammatory bowel disease patients at risk of opportunistic infections are those treated with immunomodulators. Toruner and colleagues found that corticosteroid use was more commonly associated with fungal infections. We present a case of invasive pulmonary Aspergillosis due to corticosteroid therapy in the context of a severe Ulcerative Colitis flare. We want to highlight the relationship between Aspergillus fumigatus and horses; and the use of leucocitapheresis combined with mesalazine as an effective treatment option in this patients who can not take more immunosuppressive therapy.

Ulcerative colitis (UC) treatment is focused to achieve mucosal healing, avoiding disease progression. The study aimed to evaluate the real-world effectiveness of adalimumab (ADA) in UC and to identify predictors of remission to ADA.This cohort study used data from the ENEIDA registry. Clinical response, clinical remission, endoscopic remission, adverse events (AE), colectomy, and hospitalisations were evaluated; baseline characteristics and biological parameters were compared to determine predictors of response.We included 263 patients (87 naïve and 176 previously exposed to anti-tumour necrosis factor alpha, TNF). After 12 weeks, clinical response, clinical remission, and endoscopic remission rates were 51, 26, and 14 %, respectively. The naïve group demonstrated better response to treatment than the anti-TNF-exposed group at short-term. Clinical and endoscopic remission within 1 year of treatment was better in the naïve group (65 vs. 49 and 50 vs. 35 %, respectively). The rates of AE, dose-escalation, hospitalisations, and colectomy during the first year were higher in anti-TNF-exposed patients (40, 43, and 27 % vs. 26, 21, and 11 %, respectively). Patients with primary failure and intolerance to the first anti-TNF and severe disease were associated with worse clinical response. Primary non-response to prior anti-TNF treatment and severe disease were predictive of poorer clinical remission. Low levels of C-reactive protein (CRP) and faecal calprotectin (FC) at baseline were predictors of clinical remission.In clinical practice, ADA was effective in UC, especially in anti-TNF naïve patients. FC and CRP could be predictors of treatment effectiveness.

AIM To evaluate the real-world effectiveness of golimumab in ulcerative colitis (UC) and to identify predictors of response. METHODS We conducted an observational, prospective and multi-center study in UC patients treated with golimumab, from September 2014 to September 2015. Clinical activity was assessed at wk 0 and 14 with the physician' s global clinical assessment (PGA) and the partial Mayo score. Colonoscopies and blood tests were performed, following daily-practice clinical criteria, and the results were recorded in an SPSS database. RESULTS Thirty-three consecutive patients with moderately to severely active UC were included. Among them, 54.5% were female and 42 years was the average age. Thirty percent had left-sided UC (E2) and 70% had extensive UC (E3). All patients had an endoscopic Mayo score of 2 or 3 at baseline. Twenty-seven point three percent were anti-tumor necrosis factor (TNF) treatment naive, whereas 72.7% had previously received infliximab and/or adalimumab. Sixty-nine point seven percent showed clinical response and were steroid-free at wk 14 (a decrease from baseline in the partial Mayo score of at least 3 points). Based on PGA, the clinical remission and clinical response rates were 24% and 55% respectively. Withdrawal of corticosteroids was observed in 70.8% of steroid-dependent patients at the end of the study. Three out of 10 clinical non-responders needed a colectomy. Mean fecal calprotectin value at baseline was 300 mu g/g, and 170.5 mu g/g at wk 14. Being anti-TNF treatment naive was a protection factor, which was related to better chances of reaching clinical remission. Twenty-seven point three percent of the patients required treatment intensification at 14 wk of followup. Only three adverse effects (AEs) were observed during the study; all were mild and golimumab was not interrupted. CONCLUSION This real-life practice study endorses golimumab's promising results, demonstrating its short-term effectiveness and confirming it as a safe drug during the induction phase.

Background and Aims: Amyloidosis is a rare complication of inflammatory bowel disease [IBD]; its low prevalence has hindered both descriptive and therapeutic studies. The aim of this study was to estimate the prevalence of amyloidosis in IBD and the risk factors associated with this complication. Methods: This paper presents an observational study, followed by a systematic review of the epidemiological and clinical characteristics of the disease and a review of the diagnostic and therapeutic options. Results: The prevalence of amyloidosis among IBD patients is 0.53% (95% confidence interval [CI]: 0.32–0.75), although epidemiological data suggest that it may be under-diagnosed. The phenotype most frequently associated with amyloidosis is males with aggressive and extensive Crohn’s disease, fistulising behaviour, perianal disease, and extra-intestinal complications, with the development of proteinuria and renal failure. Conclusions: Identifying risk factors of amyloidosis in IBD patients and screening for proteinuric renal dysfunction are useful to improve diagnostic accuracy. Referral of biopsies to a tertiary centre should also be considered, to improve diagnostic accuracy. Although there is no reliable evidence on the effectiveness of treatment, it seems reasonable to treat the underlying disease with potent immunosuppression to minimise inflammatory activity, thereby switching off amyloidogenesis.

The possibility of an infectious origin in inflammatory bowel disease (IBD) has been postulated since the first description of Crohn’s disease (CD). Many observations implicate bacteria as a trigger for the development of CD: lesions occur in regions with higher bacterial concentrations; aphthous ulcers occur in Peyer’s patches; inflammation resolves when the fecal stream is diverted and is reactivated following reinfusion of bowel contents; severity of the disease is correlated with bacterial density in the mucosa; granulomas can contain bacteria; and susceptible mice raised in germ-free conditions develop inflammation when bacteria are introduced in the 1990’s, several studies sought to establish a relationship with viral infections and the onset of IBD, finally concluding that no direct link had been demonstrated. In the past fifteen years, evidence relating IBD pathogenesis to Mycobacterium avium paratuberculosis, salmonella, campylobacter, etc., has been found. The tendency now under discussion to regard microbiota as the primary catalyst has led to the latest studies on microbiota as pathogens, focusing on Escherichia coli, mainly in ileal CD. The present review discusses the literature available on these “bugs”.

BACKGROUND & AIMS: Infliximab is a safe and effective therapy for ulcerative colitis (UC). We conducted a multicenter retrospective cohort study that included 7 European countries and Israel to examine whether infliximab discontinuation can be considered for patients who achieve sustained remission. METHODS: We performed a retrospective cohort study, collecting medical records from 13 tertiary care referral inflammatory bowel disease centers of all patients with UC treated with infliximab (n = 193). We compared the disease course of patients with at least 12 months of clinical remission who discontinued infliximab (n = 111) with that of patients who continued scheduled treatment (controls, n = 82). We examined the incidence rates of relapse, hospitalization and colectomy, the comparative effectiveness of different therapeutic strategies after discontinuation, and assessed the rates of response, remission, and adverse effects after infliximab reinitiation. Statistical analyses used time-to-event methods. RESULTS: In the entire cohort, 67 patients (34.7%) relapsed during the follow-up period. The incidence rate of relapse was significantly higher after discontinuation (23.3 per 100 person-years) compared with the control group (7.2 per 100 person-years) in univariable analysis (logrank P < .001 hazard ratio, 3.41 95% confidence interval, 1.88-6.20) and multivariable analysis (hazard ratio, 3.70 95% confidence interval, 2.02-6.77). Rates of hospitalization and colectomy did not differ between groups. Thiopurines appeared to be the best treatment option after infliximab discontinuation (incidence of relapse: 15.0 per 100 person-years for thiopurines, 27.4 per 100 person-years for thiopurines plus aminosalicylates, and 31.2 per 100 person-years for aminosalicylates alone log-rank P = .032). Response was regained in 77.1% of patients and remission in 51.4% of patients who re-initiated infliximab. However, 17.1% had infusion reactions and 17.1% reported other adverse events. CONCLUSIONS: In a multinational retrospective cohort study of patients with UC in sustained clinical remission, we associated discontinuation of infliximab with an increased risk of relapse. Treatment reinitiation is effective and safe.

central review of endoscopic images on patient selection and trial outcomes. Methods: We utilized data from a placebo-controlled randomized trial of Asacol®, an 800mg formulation of mesalamine, conducted in patients with mildly-to-moderately active UC (NCT01059344). Eligible patients had a UC-DAI total score of 4 10 and an endoscopy sub-score 2. Patients were randomized 1:1 to Asacol® 4.8 g/day or placebo for 10 weeks. Outcomes were assessed at weeks 6 and 10. Post-hoc exploratory analyses compared week 6 clinical and endoscopic outcomes in site investigator (SI)and central reader (CR)-defined endoscopically eligible populations, as well as outcomes in CReligible patients using SI versus CR scoring. Results: A total of 281 patients comprised the SI population. Of these, 194 (69%) were considered eligible by the CR and were included in CR-based analyses. The effect size (percent difference Asacol® minus placebo) was consistently greater for all outcomes in the CR-versus SI-defined population (see Table 1). Placebo rates were uniformly greater in the SI population due to inclusion of patients with low endoscopic disease activity as judged by the CR. No difference in effect size was observed between CRand SI-based outcomes at week 6 in the CR-defined population.
