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.

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.

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.

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.
