Effectiveness and safety of azathioprine for inflammatory pouch disorders: results from the RESERVO study of GETECCU.

Background: The usefulness of thiopurines has been poorly explored in pouchitis and other pouch disorders. Objective: To evaluate the effectiveness and safety of azathioprine as maintenance therapy in inflammatory pouch disorders. Design: This was a retrospective and multicentre study. Methods: We included patients diagnosed with inflammatory pouch disorders treated with azathioprine in monotherapy. Effectiveness was evaluated at 1 year and in the long term based on normalization of stool frequency, absence of pain, faecal urgency or fistula discharge (clinical remission), or any improvement in these symptoms (clinical response). Endoscopic response was evaluated using the Pouchitis Disease Activity Index (PDAI). Results: In all, 63 patients were included [54% males; median age, 49 (28-77) years]. The therapy was used to treat pouchitis (n = 37) or Crohn's disease of the pouch (n = 26). The rate of clinical response, remission and non-response at 12 months were 52%, 30% and 18%, respectively. After a median follow-up of 23 months (interquartile range 11-55), 19 patients (30%) were in clinical remission, and 45 (66%) stopped therapy. Endoscopic changes were evaluated in 19 cases. PDAI score decreased from 3 (range 2-4) to 1 (range 0-3). In all, 21 patients (33%) presented adverse events and 16 (25%) needed to stop therapy. Conclusion: Azathioprine may be effective in the long term for the treatment of inflammatory pouch disorders and could be included as a therapeutic option.

The Natural History of Patients With Pre-Existing and De Novo Inflammatory Bowel Disease After Solid Organ Transplantation: EITOS Study of GETECCU.

BACKGROUND: Limited data are available on the outcome of inflammatory bowel disease (IBD) in patients with solid organ transplantation (SOT). We describe the natural history of pre-existing IBD and de novo IBD after SOT. METHODS: This was a retrospective, multicenter study that included patients with pre-existing IBD at the time of SOT and patients with de novo IBD after SOT. The primary outcome was IBD progression, defined by escalation of medical treatment, surgical therapy, or hospitalization due to refractory IBD. Risk factors were identified using multivariate Cox proportional hazard analysis. RESULTS: A total of 177 patients (106 pre-existing IBD and 71 de novo IBD) were included. Most patients with pre-existing IBD (92.5%) were in remission before SOT. During follow-up, 32% of patients with pre-existing IBD had disease progression, with a median time between SOT and IBD progression of 2.2 (interquartile range, 1.3-4.6) years. In the de novo cohort, 55% of patients had disease progression with a median time to flare of 1.9 (interquartile range, 0.8-3.9) years after diagnosis. In the pre-existing IBD cohort, active IBD at the time of SOT (hazard ratio, 1.80; 95% confidence interval, 1.14-2.84; P = .012) and the presence of extraintestinal manifestations (hazard ratio, 3.10; 95% confidence interval, 1.47-6.54; P = .003) were predictive factors for IBD progression. CONCLUSIONS: One-third of patients with pre-existing IBD and about half of patients with de novo IBD have disease progression after SOT. Active IBD at the time of SOT and the presence of extraintestinal manifestations were identified as risk factors for IBD progression.

Genetic biomarkers of methotrexate response and safety in Crohn's disease: Data from the Spanish ENEIDA registry.

AIMS: Methotrexate (MTX) is used to induce and maintain remission in patients with steroid-dependent Crohn's disease (CD). Despite its proven efficacy, its use is limited due to associated adverse events. Polymorphisms involving folate pathway genes might influence MTX efficacy and toxicity. We aimed to assess the impact of certain polymorphisms on the therapeutic outcomes of MTX in CD. METHODS: Patients with CD who exclusively followed MTX monotherapy and fulfilled inclusion criteria were identified from the GETECCU ENEIDA registry. Variants of ATIC, DHFR, MTHFR, SLC19A1, ABCB1 and ABCC3 genes were analysed and their association with efficacy and toxicity was assessed. RESULTS: A total of 129 patients were included in the analysis. MTX was used at a median weekly dose of 25 mg (interquartile range, 15-25 mg) and a median time of 14 months (interquartile range, 4-52 months). Thirty-seven percent of the patients achieved disease remission with MTX monotherapy, while 34% were nonresponders (MTX failure). MTX-related toxicity occurred in 40 patients (30%), leading to MTX discontinuation in 19%. DHFR rs408626 (odds ratio [OR] 3.12, 95% confidence interval [CI] 1.22-7.69; P = .017) and MTHFR rs1801133 (OR 2.86, 95% CI 1.23-6.68; P = .015) variants, and smoking (OR 2.61, 95% CI 1.12-6.05; P = .026) were associated with a higher risk of MTX failure. Additionally, the MTHFR rs1801131 variant was associated with a higher risk of MTX-related adverse effects (OR 2.78, 95% CI 1.26-6.13, P = .011). CONCLUSION: Our study shows that variants of MTHFR and DHFR genes may be associated with MTX efficacy and adverse events in patients with CD.

Combination of granulocyte-monocyte apheresis and tofacitinib: Multicentre and retrospective study.

OBJECTIVE: Granulocyte-monocyte apheresis (GMA) has shown to be safe and effective in treating ulcerative colitis (UC), also in combination with biologics. The objective of this study is to evaluate the efficacy and safety of combining GMA after primary non-response (PNR) or loss of response (LOR) to tofacitinib (TOFA) in patients with UC. PATIENTS AND METHODS: Retrospective study including all patients with refractory UC who received GMA plus TOFA. Efficacy was assessed 1 and 6 months after finishing GMA by partial Mayo score, C-reactive protein (CRP) and fecal calprotectin (FC). Descriptive statistics and non-parametric tests were used in the statistical analysis. RESULTS: Twelve patients were included (median 46 years [IQR, 37-58]; 67% female; 67% E3). Patients were mostly receiving TOFA 10mg bid (75%), and 33% also concomitant steroids at baseline. Median partial Mayo score at baseline was 7 (IQR, 5-7), and it decreased to a median of 2 (IQR, 0-3) and 0 (IQR, 0-3) after 1 and 6 months (p=0.027 and 0.020, respectively), while no differences were found in CRP and FC. Clinical remission was achieved by 6 patients both at 1 (50%) and 6 months (67%). CF values<250mg/kg were achieved by 2 and 4 patients at 1 and 6 months (data available in 5 and 7 patients, respectively). No patient required dose-escalation of TOFA, and one patient was able to de-escalate the drug. No patient required colectomy and all patients under steroids were able to stop them. CONCLUSION: The combination of GMA and TOFA can be effective in selected cases of UC after PNR or LOR to this drug.

Safety and Effectiveness of Vedolizumab and Ustekinumab in Elderly Patients with Inflammatory Bowel Disease: A Real-Life Multicentric Cohort Study.

BACKGROUND: Data on ustekinumab and vedolizumab in the elderly inflammatory bowel disease (IBD) population are limited. The aim of the current study was to assess the safety and effectiveness of both in an elderly real-life population. METHODS: A multicentric retrospective study was performed on IBD patients who started vedolizumab or ustekinumab between 2010 and 2020. Clinical and endoscopic remission rates and (serious) adverse events (AE) were assessed. RESULTS: A total of 911 IBD patients were included, with 171 (19%) aged above 60 (111 VDZ, 60 UST). Elderly patients treated with vedolizumab or ustekinumab had an increased risk for non-IBD hospitalization (10.5% vs. 5.7%, p = 0.021) and malignancy (2.3% vs. 0.5%, p = 0.045) compared to the younger population. Corticosteroid-free clinical (50% vs. 44%; p = 0.201) and endoscopic remission rates (47.9% vs. 31%, p = 0.07) at 1 year were similar. Comparing vedolizumab to ustekinumab in the elderly population, corticosteroid-free (47.9% vs. 31%, p = 0.061) and endoscopic remission rates (66.7% vs. 64.4%, p = 0.981) were similar. Vedolizumab- and ustekinumab-treated patients had comparable infection rates (13.5% vs. 10.0%, p = 0.504), IBD flare-ups (4.5% vs. 5%, p = 1.000), the occurrence of new EIMs (13.5% vs. 10%, p = 0.504), a risk of intestinal surgery (5.4% vs. 6.7%, p = 0.742), malignancy (1.8% vs. 3.3%, p = 0.613), hospitalization (9.9% vs. 11.7%, p = 0.721), and mortality (0.9% vs. 1.7%, p = 1.000). AE risk was associated only with corticosteroid use. CONCLUSIONS: Ustekinumab and vedolizumab show comparable effectiveness and safety in the elderly IBD population. Elderly IBD patients have an increased risk for non-IBD hospitalizations and malignancy compared to the younger IBD population, with corticosteroid use as the main risk factor.

IMPACT OF MESALAZINE ON THE RESPONSE TO COVID-19 VACCINATION IN PATIENTS WITH INFLAMMATORY BOWEL DISEASE. RESULTS OF A PROSPECTIVE MULTICENTRE STUDY OF GETECCU (VACOVEII STUDY). / IMPACTO DE LA MESALAZINA EN LA RESPUESTA A LA VACUNACIÓN CONTRA EL COVID-19 EN PACIENTES CON ENFERMEDAD INFLAMATORIA INTESTINAL. RESULTADOS DE UN ESTUDIO PROSPECTIVO MULTICÉNTRICO DE GETECCU (VACOVEII).

OBJECTIVE: the recommendations of the Spanish Ministry of Health on vaccination in risk groups include mesalazine among the treatments with a possible negative effect on its effectiveness. However, this is not the recommendation of most experts. Our objective was to evaluate the effect of mesalazine on the humoral response to the SARS-CoV-2 vaccine in patients with inflammatory bowel disease (IBD). METHODS: VACOVEII is a Spanish, prospective, multicenter study promoted by GETECCU, which evaluates the effectiveness of the SARS-CoV-2 vaccine in patients with IBD. This study includes IBD patients who have recieved the full vaccination schedule and without previous COVID-19 infection. Seroconversion was set at 260 BAU/mL (centralized determination) and was assessed 6 months after full vaccination. In this subanalysis of the study, we compare the effectivenes of the vaccine between patients treated with mesalazine and patients without treatment. RESULTS: A total of 124 patients without immunosuppressive therapy were included, of which 32 did not receive any treatment and 92 received only mesalazine. Six months after full vaccination, no significant differences are observed in the mean concentrations of IgG anti-S between both groups. In the multivariate analysis, antibody titers were independently associated with the use of mRNA vaccines and with SARS-CoV-2 infection. CONCLUSION: Mesalazine does not have a negative effect on the response to SARS-CoV-2 vaccines in IBD patients.

Recommendations on the management of severe obesity in patients with inflammatory bowel disease of the Spanish Group on Crohn's Disease and Ulcerative Colitis (GETECCU), Spanish Society of Obesity (SEEDO), Spanish Association of Surgery (AEC) and Spanish Society of Digestive Endoscopy (SEED). / Recomendaciones sobre el manejo de la obesidad grave en pacientes con enfermedad inflamatoria intestinal del Grupo Español de Trabajo en Enfermedad Inflamatoria Intestinal (GETECCU), Sociedad Española de Obesidad (SEEDO), Asociación Española de Cirugía (AEC) y Sociedad Española de Endoscopia Digestiva (SEED).

Obesity is a multifactorial, chronic, progressive and recurrent disease considered a public health issue worldwide and an important determinant of disability and death. In Spain, its current prevalence in the adult population is about 24% and an estimated prevalence in 2035 of 37%. Obesity increases the probability of several diseases linked to higher mortality such as diabetes, cardiovascular disease, hyperlipidemia, arterial hypertension, non-alcoholic fatty liver disease, several types of cancer, or obstructive sleep apnea. On the other hand, although the incidence of inflammatory bowel disease (IBD) is stabilizing in Western countries, its prevalence already exceeds 0.3%. Paralleling to general population, the current prevalence of obesity in adult patients with IBD is estimated at 15-40%. Obesity in patients with IBD could entail, in addition to its already known impact on disability and mortality, a worse evolution of the IBD itself and a worse response to treatments. The aim of this document, performed in collaboration by four scientific societies involved in the clinical care of severe obesity and IBD, is to establish clear and concise recommendations on the therapeutic possibilities of severe or typeIII obesity in patients with IBD. The document establishes general recommendations on dietary, pharmacological, endoscopic, and surgical treatment of severe obesity in patients with IBD, as well as pre- and post-treatment evaluation.

Human Leukocyte Antigen Signatures as Pathophysiological Discriminants of Microscopic Colitis Subtypes.

BACKGROUND AND AIMS: Microscopic colitis [MC] is currently regarded as an inflammatory bowel disease that manifests as two subtypes: collagenous colitis [CC] and lymphocytic colitis [LC]. Whether these represent a clinical continuum or distinct entities is, however, an open question. Genetic investigations may contribute important insight into their respective pathophysiologies. METHODS: We conducted a genome-wide association study [GWAS] meta-analysis in 1498 CC, 373 LC patients, and 13 487 controls from Europe and the USA, combined with publicly available MC GWAS data from UK Biobank and FinnGen [2599 MC cases and 552 343 controls in total]. Human leukocyte antigen [HLA] alleles and polymorphic residues were imputed and tested for association, including conditional analyses for the identification of key causative variants and residues. Genetic correlations with other traits and diagnoses were also studied. RESULTS: We detected strong HLA association with CC, and conditional analyses highlighted the DRB1*03:01 allele and its residues Y26, N77, and R74 as key to this association (best p = 1.4 × 10-23, odds ratio [OR] = 1.96). Nominally significant genetic correlations were detected between CC and pneumonia [rg = 0.77; p = 0.048] and oesophageal diseases [rg = 0.45, p = 0.023]. An additional locus was identified in MC GWAS analyses near the CLEC16A and RMI2 genes on chromosome 16 [rs35099084, p = 2.0 × 10-8, OR = 1.31]. No significant association was detected for LC. CONCLUSION: Our results suggest CC and LC have distinct pathophysiological underpinnings, characterised by an HLA predisposing role only in CC. This challenges existing classifications, eventually calling for a re-evaluation of the utility of MC umbrella definitions.

A booster dose of SARS-COV-2 vaccine improves suboptimal seroconversion rates in patients with inflammatory bowel disease. Results of a prospective multicenter study of GETECCU (VACOVEII study).

BACKGROUND: The response to SARS-CoV-2 vaccination decreases in inflammatory bowel disease (IBD) patients, specially under anti-TNF treatment. However, data on medium-term effectiveness are limited, specially using new recommended seroconversion rate (>260BAU/mL). Our aim was to evaluate the 6-month>260 BAU-seroconversion rate after full vaccination and after booster-dose. METHODS: VACOVEII is a Spanish multicenter, prospective study promoted by GETECCU. IBD patients full vaccinated against SARS-CoV-2 and without previous COVID-19 infection, treated or not with immunosuppressants, were included. The booster dose was administered 6 months after the full vaccination. Seroconversion was set at 260BAU/mL, according to most recent recommendations and was assessed 6 months after the full vaccination and 6 months after booster-dose. RESULTS: Between October 2021 and March 2022, 313 patients were included (124 no treatment or mesalazine; 55 immunomodulators; 87 anti-TNF; 19 anti-integrin; and 28 ustekinumab). Most patients received mRNA-vaccines (86%). Six months after full vaccination, overall seroconversion rate was 44.1%, being significantly lower among patients on anti-TNF (19.5%, p<0.001) and ustekinumab (35.7%, p=0.031). The seroconversion rate after booster was 92%. Again, anti-TNF patients had a significantly lower seroconversion rate (67%, p<0.001). mRNA-vaccine improved seroconversion rate (OR 11.720 [95% CI 2.26-60.512]). CONCLUSION: The full vaccination regimen achieves suboptimal response in IBD patients, specially among those anti-TNF or ustekinumab. The booster dose improves seroconversion rate in all patients, although it remains limited in those treated with anti-TNF. These results reinforce the need to prioritize future booster doses in patients on immunosuppressants therapy, specially under anti-TNF, and using mRNA-vaccines.

The Risk of Developing Disabling Crohn's Disease: Validation of a Clinical Prediction Rule to Improve Treatment Decision Making.

BACKGROUND: Crohn's disease (CD) is characterized by the development of complications over the course of the disease. It is crucial to identify predictive factors of disabling disease, in order to target patients for early intervention. We evaluated risk factors of disabling CD and developed a prognostic model. METHODS: In total, 511 CD patients were retrospectively analyzed. Univariate and multivariate logistic regression analyses were used to identify demographic, clinical, and biological risk factors. A predictive nomogram model was developed in a subgroup of patients with noncomplicated CD (inflammatory pattern and no perianal disease). RESULTS: The rate of disabling CD within 5 years after diagnosis was 74.6%. Disabling disease was associated with gender, location of disease, requirement of steroids for the first flare, and perianal lesions. In the subgroup of patients (310) with noncomplicated CD, the rate of disabling CD was 80%. In the multivariate analysis age at onset <40 years (OR = 3.46, 95% confidence interval [CI] = 1.52-7.90), extensive disease (L3/L4) (OR = 2.67, 95% CI = 1.18-6.06), smoking habit (OR = 2.09, 95% CI = 1.03-4.27), requirement of steroids at the first flare (OR = 2.20, 95% CI = 1.09-4.45), and albumin (OR = 0.59, 95% CI = 0.36-0.96) were associated with development of disabling disease. The developed predictive nomogram based on these factors presented good discrimination, with an area under the receiver operating characteristic curve of 0.723 (95% CI: 0.670-0.830). CONCLUSION: We identified predictive factors of disabling CD and developed an easy-to-use prognostic model that may be used in clinical practice to help identify patients at high risk and address treatment effectively.

Relevance of patient-reported outcome measures (PROM) and patient-reported experience measures (PREM) to assess disease status and quality of care in patients with inflammatory bowel disease.

The 21st century has brough us a paradigm shift regarding patients care: the conventional physician-focused model of care has now changed into a patient-centered mode that puts the patient at the center of his own healthcare. Establishing a non-prescriptive and collaborative therapeutic approach, empowering patients to make major decisions on their management, and strict respect to the patient's autonomy are the major drivers of this patient-centered care. Among other multiple collectives, this change has greatly impacted patients and physicians who deal with inflammatory bowel disease (IBD).

Ustekinumab and vedolizumab for the prevention of postoperative recurrence of Crohn's disease: Results from the ENEIDA registry.

BACKGROUND: Anti-TNF agents are the only effective biological agents for the prevention of postoperative recurrence (POR) in Crohn's disease (CD). However, they are contraindicated or have been shown to fail in some patients. Although ustekinumab and vedolizumab were licensed for CD some years ago, data in this setting are scarce. METHODS: All CD patients in whom ustekinumab or vedolizumab was prescribed for the prevention of POR within three months of ileocolonic resection with anastomosis were identified from the ENEIDA registry. The development of endoscopic, clinical and surgical POR was registered. RESULTS: Forty patients were treated for the prevention of POR with ustekinumab and 25 were treated with vedolizumab. Eighty per cent had at least one risk factor for POR (prior resections, active smoking, perianal disease or penetrating disease behaviour). All the patients had been exposed to anti-TNF therapy. After a median follow-up of 17 and 26 months, the cumulative probability of clinical POR at 12 months after surgery was 32% and 30% for ustekinumab and vedolizumab, respectively. Endoscopic assessment within the first 18 months after surgery was available for 80% of the patients on ustekinumab and 70% for those on vedolizumab. The rate of endoscopic POR was 42% for ustekinumab and 40% for vedolizumab. One patient treated with ustekinumab and two with vedolizumab underwent a new intestinal resection. CONCLUSIONS: Ustekinumab and vedolizumab seem to be effective in the prevention of POR in patients at high risk. Our results warrant controlled trials comparing these drugs with conventional therapies.

Risk Factors for COVID-19 in Inflammatory Bowel Disease: A National, ENEIDA-Based Case-Control Study (COVID-19-EII).

(1) Scant information is available concerning the characteristics that may favour the acquisition of COVID-19 in patients with inflammatory bowel disease (IBD). 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.

SARS-CoV-2 vaccine acceptance among gastroenterologists and inflammatory bowel disease patients: VACUNEII project / Aceptación de la vacuna frente a SARS-CoV-2 entre gastroenterólogos y pacientes con enfermedad inflamatoria intestinal: proyecto VACUNEII

Introduction: Several vaccines against SARS-CoV-2 are currently in use and are recommended in inflammatory bowel disease (IBD) patients. Data are scarce about the gastroenterologists and IBD patient's acceptance of SARS-CoV-2 vaccines. The aim of the study was to evaluate the intention to get vaccination with SARS-CoV-2 vaccine among IBD patients from gastroenterologists and patient's perspective. Methods: An online anonymous survey was sent to 8000 patients from ACCU-Spain and 1000 members of the GETECCU. Three invitations were sent between October-December 2020. Descriptive analyses were performed, comparing physicians and patients responses by standard statistical analyses. Results: 144 gastroenterologists [63% female, mean age 43 years (SD 9.5)], and 1302 patients [72% female, mean age 43 years (SD 12)] responded to the survey. 95% of the physicians recommended SARS-CoV-2 vaccine for IBD patients and 87% consider that their vaccination strategies has not changed after the pandemic compared to 12% who considered that they currently refer more patients to vaccination. Regarding to IBD patients, only 43% of patients were willing to receive the vaccine and 43% were not sure. Male sex (p<0.001) and mesalazine treatment (p=0.021) were positively associated with SARS-CoV-2 vaccine acceptance. After multivariate analysis, only male sex was significantly associated with vaccination intent (OR=1.6; 95% confidence interval=1.2–2.0; p=0.001). Conclusions: Gastroenterologists and patient's perspective about SARS-CoV-2 are different. Future efforts to increase COVID-19 vaccine and decrease unfounded beliefs among IBD patients are needed.(AU)

Introducción: Actualmente en el mercado hay diferentes vacunas frente a SARS-CoV-2 que se recomiendan en pacientes con enfermedad inflamatoria intestinal (EII). No tenemos suficiente evidencia sobre la aceptación de este tipo de vacunas. El objetivo del estudio fue evaluar la aceptación de la vacuna frente a SARS-CoV-2 por parte de gastroenterólogos y pacientes con EII. Métodos: Se realizó una encuesta online a 8.000 pacientes de ACCU-España y 1.000 miembros de GETECCU. Se enviaron tres invitaciones entre octubre y diciembre de 2020. Se realizó un análisis descriptivo, comparando las respuestas de médicos y pacientes. Resultados: 144 gastroenterólogos (63% mujeres, edad media 43años [DE9,5]) y 1.302 pacientes (72% mujeres, edad media 43años [DE12]) respondieron a la encuesta. El 95% de los médicos recomendaban la vacuna frente a SARS-CoV-2 en pacientes con EII, el 87% consideraron que su estrategia de vacunación frente a diferentes vacunas no había cambiado tras la pandemia, frente al 12% que consideraban que actualmente remitían más pacientes a vacunación. En cuanto a los pacientes con EII, solo el 43% aceptaban la vacunación frente a SARS-CoV-2, frente al 43% que no estaban seguros. El sexo masculino (p<0,001) y el uso de mesalazina (p=0,021) se asoció de forma positiva con la aceptación de la vacuna. En el análisis multivariante, solo el sexo masculino fue asociado significativamente con la intención de vacunarse (OR=1,6; IC95%=1,2-2,0; p=0,001). Conclusiones: La perspectiva de gastroenterólogos y pacientes con EII con respecto a la vacunación frente a SARS-CoV-2 es diferente. Es necesario realizar esfuerzos para incrementar el uso de la vacuna y disminuir falsas creencias.(AU)

Recomendaciones del Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa sobre la importancia, el cribado y la vacunación en pacientes con enfermedad inflamatoria intestinal / Recommendations of the Spanish Group on Crohn's Disease and Ulcerative Colitis on the importance, screening and vaccination in inflammatory bowel disease patients

Los pacientes con enfermedad inflamatoria intestinal (EII) pueden requerir diferentes tratamientos inmunosupresores a lo largo del curso de su enfermedad. Por ello, es fundamental evaluar el estado de inmunización en el momento del diagnóstico o, si no es posible, siempre antes de iniciar un tratamiento inmunosupresor, y administrar las vacunas apropiadas. El objetivo del presente documento es establecer unas recomendaciones claras y concisas sobre la vacunación en pacientes con EII en diferentes escenarios de práctica clínica, incluyendo situaciones especiales como la vacunación en la edad pediátrica, el embarazo, la lactancia o en viajes al extranjero. Se presentan las diferencias entre vacunas inactivadas y atenuadas, los diferentes grados de inmunosupresión y su relación con las pautas de administración de las diferentes vacunas (tanto obligatorias como opcionales) recomendadas a los pacientes con EII. En el documento, se establecen 17 recomendaciones basadas en la evidencia científica disponible y opinión de expertos. En la elaboración de estas recomendaciones del Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa ha participado un equipo multidisciplinar con amplia experiencia en EII y vacunación formado por especialistas de gastroenterología, pediatría, enfermería y farmacia.(AU)

Patients with inflammatory bowel disease (IBD) may require different immunosuppressive treatments throughout their illness. It is essential to assess the immunization status of patients at diagnosis or, if this is not possible, at least before the beginning of immunosuppressive therapy and, subsequently, administering the appropriate vaccines. Therefore, the aim of this work is to establish clear and concise recommendations on vaccination in patients with IBD in the different settings of our clinical practice including vaccination in children, during pregnancy, breastfeeding or on trips. This consensus document emphasises the differences between inactivated and attenuated vaccines and the different degrees of immunosuppression and correlates them with the administration of both mandatory and optional vaccines recommended to our patients with IBD. Finally, as a summary, 17 recommendations are established based on the available scientific evidence and expert opinion. A multidisciplinary team with extensive experience in IBD and vaccination, made up of specialists in gastroenterology, paediatrics, nursing and pharmacy, has participated in the preparation of these recommendations of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis.

Mucosal Interleukin-10 depletion in steroid-refractory Crohn's disease patients.

BACKGROUND: Previous studies suggested that Interleukin-10 (IL-10) depletion in Crohn's disease (CD) could predict outcome. AIM: To determine IL-10 in blood and at different intestinal locations in patients with active CD and to assess its potential prognostic capacity to identify aggressive CD. METHODS: Twenty-three patients with CD were included. Ulcerative colitis (UC), infectious colitis and healthy individuals acted as controls. Serum and mucosal samples were taken at baseline and 1 month after steroid initiation in CD patients. Patients were classified according to steroid response. Control samples were obtained from different intestinal locations. IL-10 expression was measured with real-time polymerase chain reaction, immunofluorescence (intestine) and ELISA (serum, biopsy cultures' supernatants and tissue homogenates). RESULTS: CD and UC showed an increase in IL-10 messenger RNA (mRNA) versus controls (p < .0001) in mucosa, whereas IL-10 protein secretion was increased in all types of intestinal inflammation (p < .001). No differences in IL-10 mRNA were found in CD at baseline regarding steroid response, but levels decreased in non-responders versus responders (p = .027) and were restored with rescue therapy. Serum IL-10 was increased in steroid-refractory CD at baseline and after treatment. CONCLUSIONS: Abnormal IL-10 levels in refractory patients in both mucosa and blood have physiopathological relevance and may have potential clinical applications.

Performance of Screening Strategies for Latent Tuberculosis Infection in Patients with Inflammatory Bowel Disease: Results from the ENEIDA Registry of GETECCU.

(1) Aims: Patients receiving antitumor necrosis factor (anti-TNF) therapy are at risk of developing tuberculosis (TB), usually due to the reactivation of a latent TB infection (LTBI). LTBI screening and treatment decreases the risk of TB. This study evaluated the diagnostic performance of different LTBI screening strategies in patients with inflammatory bowel disease (IBD). (2) Methods: Patients in the Spanish ENEIDA registry with IBD screened for LTBI between January 2003 and January 2018 were included. The diagnostic yield of different strategies (dual screening with tuberculin skin test [TST] and interferon-×¥-release assay [IGRA], two-step TST, and early screening performed at least 12 months before starting biological treatment) was analyzed. (3) Results: Out of 7594 screened patients, 1445 (19%; 95% CI 18−20%) had LTBI. Immunomodulator (IMM) treatment at screening decreased the probability of detecting LTBI (20% vs. 17%, p = 0.001). Regarding screening strategies, LTBI was more frequently diagnosed by dual screening than by a single screening strategy (IGRA, OR 0.60; 95% CI 0.50−0.73, p < 0.001; TST, OR 0.76; 95% CI 0.66−0.88, p < 0.001). Two-step TST increased the diagnostic yield of a single TST by 24%. More cases of LTBI were diagnosed by early screening than by routine screening before starting anti-TNF agents (21% [95% CI 20−22%] vs. 14% [95% CI 13−16%], p < 0.001). The highest diagnostic performance for LTBI (29%) was obtained by combining early and TST/IGRA dual screening strategies in patients without IMM. (4): Conclusions: Both early screening and TST/IGRA dual screening strategies significantly increased diagnostic performance for LTBI in patients with IBD, with optimal performance achieved when they are used together in the absence of IMM.
