RESUMEN

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.

RESUMEN

OBJECTIVE: Granulocyte-monocyte apheresis (GMA) has shown to be safe and effective in ulcerative colitis (UC), also in combination with biologics, mainly with anti-TNF. The aim of this study was to evaluate the efficacy and safety of combining GMA after primary non-response (PNR) or loss of response (LOR) to ustekinumab (UST) in patients with UC. PATIENTS AND METHODS: A retrospective study was performed in 12 IBD Units, including all patients with refractory UC or unclassified IBD (IBD-U) who received combined GMA plus UST. The number and frequency of GMA sessions, filtered blood volume and time of each session were registered. 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: Seventeen patients were included (15 UC, 2 IBD-U; median age 47 years [IQR, 35-61]; 59% male; 53% E3). Most patients (89%) had prior exposure to anti-TNF agents and 53% to vedolizumab; 65% were also receiving steroids at baseline. Median partial Mayo score at baseline was 6 (IQR, 5-7) and it significantly decreased after 1 and 6 months (p=0.042 and 0.007, respectively). Baseline FC significantly decreased after 6 months (p=0.028) while no differences were found in CRP. During follow-up, 18% patients started a new biologic therapy and 12% required surgery; 64% of patients under steroids were able to discontinue them. Adverse events were reported in one patient. CONCLUSION: GMA can recapture the response to UST in selected cases of UC after PNR or LOR to this drug.

RESUMEN

INTRODUCTION: Collaboration between Primary Care (PC) and Gastroenterology in inflammatory bowel disease (IBD) is crucial to provide high-quality healthcare. The aim of this study is to analyse the relationship between PC and gastroenterologists at a national level in order to identify areas for improvement in the management of patients with inflammatory bowel disease (IBD) and how to address them, with the aim of subsequently developing concrete proposals and projects between SEMERGEN and GETECCU. METHODS: Descriptive, observational, cross-sectional study, was carried out using an anonymous online questionnaire between October 2021 and March 2022. RESULTS: A total of 157 surveys from Gastroenterology and 222 from PC were collected. 43.8% and 34.3% of gastroenterologists and family practitioners, respectively, considered that there was a good relationship between the units. The level of knowledge from family practitioners regarding different aspects of IBD out of 10 was: clinical 6.67±1.48, diagnosis 6.47±1.46, treatment 5.63±1.51, follow-up 5.53±1.68 and complications 6.05±1.54. The perception of support between both units did not exceed 4.5 on a scale from 0 to 10 in either of the surveys. The most highly voted improvement proposals were better coordination between the units, implementation of IBD units, and nursing collaboration. CONCLUSION: There are deficiencies in the relationship between PC and Gastroenterology with special dedication to IBD that require the efforts of the scientific societies that represent them for greater coordination with the development of joint protocols and agile, fast, and effective communication channels.

RESUMEN

Adherent-invasive E. coli (AIEC) is a pathotype associated with the etiopathogenesis of Crohn's disease (CD), albeit with an as-yet unclear role. The main pathogenic mechanisms described for AIEC are adherence to epithelial cells, invasion of epithelial cells, and survival and replication within macrophages. A few virulence factors have been described as participating directly in these phenotypes, most of which have been evaluated only in AIEC reference strains. To date, no molecular markers have been identified that can differentiate AIEC from other E. coli pathotypes, so these strains are currently identified based on the phenotypic characterization of their pathogenic mechanisms. The identification of putative AIEC molecular markers could be beneficial not only from the diagnostic point of view but could also help in better understanding the determinants of AIEC pathogenicity. The objective of this study was to identify molecular markers that contribute to the screening of AIEC strains. For this, we characterized outer membrane protein (OMP) profiles in a group of AIEC strains and compared them with the commensal E. coli HS strain. Notably, we found a set of OMPs that were present in the AIEC strains but absent in the HS strain. Moreover, we developed a PCR assay and performed phylogenomic analyses to determine the frequency and distribution of the genes coding for these OMPs in a larger collection of AIEC and other E. coli strains. As result, it was found that three genes (chuA, eefC, and fitA) are widely distributed and significantly correlated with AIEC strains, whereas they are infrequent in commensal and diarrheagenic E. coli strains (DEC). Additional studies are needed to validate these markers in diverse strain collections from different geographical regions, as well as investigate their possible role in AIEC pathogenicity.

RESUMEN

OBJECTIVES: This multicenter cross-sectional study was conducted to assess the psychosocial impact of COVID-19 on patients with inflammatory bowel disease (IBD) in Spain during lockdown and the first wave of the pandemic. PATIENTS AND METHODS: A self-report questionnaire that integrated the Spanish version of the Depression, Anxiety and Stress Scale-21 items (DASS-21) and the Perceived Stress Questionnaire (PSS) was designed to gather sociodemographic data and information related to the effects of lockdown on the lives of IBD patients. Twelve IBD units invited their patients to answer the anonymous online survey between the 1st July and the 25th August 2020. RESULTS: Of the 693 survey participants with IBD, 67% were women and the mean age was 43 (SD 12). Sixty-one percent had ulcerative colitis, 36% Crohn's disease and 3% indeterminate colitis. DASS-21 scores indicate that during lockdown the estimated prevalence of depression was 11% [95% CI 8.2-13%], anxiety 20% [95% CI 17 to 23%] and stress 18% [95% CI 8.2-13%]. Multivariate analysis showed that the perceived high risk of COVID-19 infection because of having IBD and maladaptation to government measures to reduce the spread of disease doubled the risk of anxiety and stress during lockdown. CONCLUSIONS: In the short-term, lockdown during the COVID-19 pandemic seemed to have an impact on the already affected mental health of our IBD patients in Spain.

RESUMEN

Although most patients with ulcerative colitis should be given topical treatment, different studies have shown that they are underused in clinical practice. The purpose of this article is to answer 10 specific questions about which drugs are available for topical use in the treatment of ulcerative colitis, and their characteristics in terms of formulation, dosage, presentation, application and proximal distribution of rectal-administered drugs. The efficacy of available topical drugs and the benefits of combining different formulations and routes of administration, and their usefulness during disease remission are evaluated. Finally, a series of recommendations addressed to patients are given on the correct application of topical treatment.

RESUMEN

Objective: To evaluate the effectiveness and safety of the combination of granulocyte-monocyte apheresis (GMA) after loss of response (LOR) to anti-tumor necrosis factor (TNF) agents in ulcerative colitis (UC). Materials and methods: A retrospective, multicenter study was performed in 11 inflammatory bowel disease (IBD) Units. Clinical remission was defined as a partial Mayo score ≤2. The effectiveness of the treatment was evaluated by the partial Mayo score and the rate of anti-TNF intensification, switch, swap or colectomy. Results: Forty-seven patients with ulcerative colitis were included (mean age 35 years, mean disease duration 52 months, 66% male and 59% extensive colitis). Twenty-three subjects were receiving infliximab, eighteen adalimumab and six golimumab. GMA was combined after a primary non-response (49%) or secondary loss of response (51%) to anti-TNF therapy. We observed a significant decrease in partial Mayo score and fecal calprotectin after GMA. Fifteen patients (32%) responded to the combination therapy without anti-TNF intensification, switch, swap or colectomy. Eight patients (17%) underwent colectomy. Two patients (4%) presented adverse events related to the technique. Conclusions: Combination of GMA and anti-tumor necrosis factor is a safe and effective treatment after the loss of response to these biologic agents, with a significant decrease of the clinical disease activity and biomarkers, in a population with limited therapeutic alternatives.

RESUMEN

Human colon lipid analysis by imaging mass spectrometry (IMS) demonstrates that the lipid fingerprint is highly sensitive to a cell's pathophysiological state. Along the colon crypt axis, and concomitant to the differentiation process, certain lipid species tightly linked to signaling (phosphatidylinositols and arachidonic acid (AA)-containing diacylglycerophospholipids), change following a rather simple mathematical expression. We extend here our observations to ethanolamine plasmalogens (PlsEtn), a unique type of glycerophospholipid presenting a vinyl ether linkage at sn-1 position. PlsEtn distribution was studied in healthy, adenomatous, and carcinomatous colon mucosa sections by IMS. In epithelium, 75% of PlsEtn changed in a highly regular manner along the crypt axis, in clear contrast with diacyl species (67% of which remained constant). Consistently, AA-containing PlsEtn species were more abundant at the base, where stem cells reside, and decreased while ascending the crypt. In turn, mono-/diunsaturated species experienced the opposite change. These gradients were accompanied by a gradual expression of ether lipid synthesis enzymes. In lamina propria, 90% of stromal PlsEtn remained unchanged despite the high content of AA and the gradient in AA-containing diacylglycerophospholipids. Finally, both lipid and protein gradients were severely affected in polyps and carcinoma. These results link PlsEtn species regulation to cell differentiation for the first time and confirm that diacyl and ether species are differently regulated. Furthermore, they reaffirm the observations on cell lipid fingerprint image sensitivity to predict cell pathophysiological status, reinforcing the translational impact both lipidome and IMS might have in clinical research.

RESUMEN

BACKGROUND: Granulocyte and monocyte apheresis is the main non-pharmacological treatment for inflammatory bowel disease (IBD), but we do not know how well accepted it is by patients in our setting. AIM: To determine how granulocyte and monocyte apheresis is perceived by patients in clinical practice in Spain. METHODS: Outpatients treated with granulocyte and monocyte apheresis in five IBD Units in Spain were asked to fill in a 14-item questionnaire. RESULTS: Fifty-two patients completed the questionnaire (88% ulcerative colitis, 12% Crohn's disease; 44% female; age 35 years [IQR 23-51]). Granulocyte and monocyte apheresis was generally well tolerated and well accepted. Very few of the participants regarded the length of the sessions as a limitation. The gastrointestinal symptoms, however, were a frequent concern, both in terms of attending to receive treatment and during the sessions. Overall, 44% were satisfied with the treatment effectiveness. Sixty percent (60%) claimed to be satisfied with the therapy overall, but this was influenced by the patients' clinical response to the therapy. Eighty-two percent (82%) of participants said they would agree to be treated with this technique again in the future, regardless of the response to the treatment. CONCLUSIONS: Granulocyte and monocyte apheresis is well tolerated and accepted by patients with IBD. Although we found no significant differences according to type of IBD or apheresis regimen, patient perception was affected by clinical effectiveness.

RESUMEN

AIMS: To establish recommendations for the management of psychological problems affecting patients with inflammatory bowel disease (IBD). METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

RESUMEN

Membrane lipids are gaining increasing attention in the clinical biomarker field, as they are associated with different pathologic processes such as cancer or neurodegenerative diseases. Analyzing human colonoscopic sections by matrix assisted laser/desorption ionization (MALDI) mass spectrometry imaging techniques, we identified a defined number of lipid species changing concomitant to the colonocyte differentiation and according to a quite simple mathematical expression. These species felt into two lipid families tightly associated in signaling: phosphatidylinositols and arachidonic acid-containing lipids. On the other hand, an opposed pattern was observed in lamina propria for AA-containing lipids, coinciding with the physiological distribution of the immunological response cells in this tissue. Importantly, the lipid gradient was accompanied by a gradient in expression of enzymes involved in lipid mobilization. Finally, both lipid and protein gradients were lost in adenomatous polyps. The latter allowed us to assess how different a single lipid species is handled in a pathological context depending on the cell type. The strict patterns of distribution in lipid species and lipid enzymes described here unveil the existence of fine regulatory mechanisms orchestrating the lipidome according to the physiological state of the cell. In addition, these results provide solid evidence that the cell lipid fingerprint image can be used to predict precisely the physiological and pathological status of a cell, reinforcing its translational impact in clinical research.

RESUMEN

OBJECTIVES: Given the importance of tobacco smoking (TS) as the only environmental factor repeatedly linked to the development of the Crohn's disease (CD), it is surprising that very few prospective studies have assessed whether TS is associated with an increased frequency of clinical relapse. Our aim was to evaluate the current impact of TS on disease relapse and the clinical benefit of quitting smoking in the present era of widespread use of anti-TNF drugs and immunosuppressants. METHODS: This was a multicenter prospective cohort study, which included 573 CD patients in clinical remission with various smoking habits. All smokers were advised to quit. Patients not exposed to tobacco before inclusion (non- and former smokers), continuing smokers, and quitters were compared regarding differences in disease outcomes during a follow-up of 4 years. RESULTS: A total of 148 continuing smokers, 190 nonsmokers, 160 former smokers, and 75 quitters were included. In comparison with nonsmokers, continuing smokers relapsed more frequently with an incidence rate ratio of 1.53 (95% confidence interval (CI): 1.10-2.17). Former smokers and quitters had similar relapse incidences compared with nonsmokers. Smoking was an independent predictor for disease relapse in the multivariate analysis (hazard ratio: 1.58 (95% CI 1.20-2.09). In the time-dependent analysis, continuing smokers had earlier relapse, regardless of anti-TNF or immunosuppressant use. CONCLUSIONS: Continuing smokers have more disease relapses, and patients who quit smoking have a similar relapse incidence compared with nonsmokers.

RESUMEN

INTRODUCTION: Randomized controlled trials provide the best scientific evidence for the efficacy of biological drugs in inflammatory bowel disease (IBD). However, findings obtained from these trials might not be reproducible in clinical practice. This study aimed to estimate the percentage of patients with IBD treated with biologics who would have been eligible for randomized controlled trials, and to compare the theoretical efficacy of biological drugs with their effectiveness in clinical practice. METHODS: We performed a retrospective multicenter study in 375 patients with IBD treated with anti-TNF agents and followed-up for 1 year. The eligibility criteria for the trial were taken from the ACCENT, SONIC, ACT, CLASSIC and CHARM trials. Eligible patients were included in a second analysis to compare results in clinical practice versus those hypothetically obtained if the patient had been included in a trial. RESULTS: Only 45.6% of 375 patients would have been eligible for pivotal trials. One-year clinical benefit (remission or response) was similar for eligible and non-eligible cohorts (68.4% vs. 68.6%, P=.608). The clinical benefit was greater for current clinical practice than for a hypothetical trial situation (68.4% vs. 44.4%, P<.001) in eligible patients. CONCLUSION: More than half of patients with IBD treated with biologic drugs would not be represented in pivotal trials. The effectiveness of anti-TNF drugs in clinical practice exceeds their theoretical efficacy.

RESUMEN

Imaging mass spectrometry is becoming a reference technique in the field of lipidomics, due to its ability to map the distribution of hundreds of species in a single run, along a tissue section. The next frontier is now achieving increasing resolution powers to offer cellular (or even sub-cellular) resolution. Thus, the new spectrometers are equipped with sophisticated optical systems to decrease the laser spot to <30 µm. Here, we demonstrate that by using the correct matrix (i.e., a matrix that maximizes ion detection and forms small crystals) and a careful preparation, it is possible to achieve resolutions of ∼5-10 µm, even with spectrometers equipped with non-optimal optics, which produces laser spots of 50 µm or even larger. As a proof of concept, we present images of distributions of lipids, both in positive and negative ion mode, over human colon endoscopic sections, recorded using 2-mercaptobenzothiazole for positive ion mode and 2,5-diaminonaphtalene for negative ion mode and an LTQ-Orbitrap XL, equipped with a matrix-assisted laser desorption ionization (MALDI) source that produces astigmatic laser spots. Graphical Abstract Imaging mass spectrometry is becoming an invaluable technique to complement traditional histology, but still higher resolutions are required. Here we deal with such issue.

RESUMEN

BACKGROUND: Despite research, there are still controversial areas in the management of Crohn's disease (CD). OBJECTIVE: To establish practical recommendations on using anti-tumour necrosis factor (TNF) drugs in patients with moderate-to-severe CD. METHODS: Clinical controversies in the management of CD using anti-TNF therapies were identified. A comprehensive literature review was performed, and a national survey was launched to examine current clinical practices when using anti-TNF therapies. Their results were discussed by expert gastroenterologists within a nominal group meeting, and a set of statements was proposed and tested in a Delphi process. RESULTS: Qualitative study. The survey and Delphi process were sent to 244 CD-treating physicians (response rate: 58%). A total of 14 statements were generated. All but two achieved agreement. These statements cover: (1) use of first-line non-anti-TNF biological therapy; (2) role of HLA-DQA1*05 in daily practice; (3) attitudes in primary non-response and loss of response to anti-TNF therapy due to immunogenicity; (4) use of ustekinumab or vedolizumab if a change in action mechanism is warranted; (5) anti-TNF drug level monitoring; (6) combined therapy with an immunomodulator. CONCLUSION: This document sought to pull together the best evidence, experts' opinions, and treating physicians' attitudes when using anti-TNF therapies in patients with CD.

RESUMEN

Inflammatory Bowel Disease (IBD) comprises a heterogeneous group of chronic inflammatory conditions of the gastrointestinal tract that include ulcerative colitis (UC) and Crohn's disease. Although the etiology is not well understood, IBD is characterized by a loss of the normal epithelium homeostasis that disrupts the intestinal barrier of these patients. Previous work by our group demonstrated that epithelial homeostasis along the colonic crypts involves a tight regulation of lipid profiles. To evaluate whether lipidomic profiles conveyed the functional alterations observed in the colonic epithelium of IBD, we performed matrix-assisted laser desorption ionization-mass spectrometry imaging (MALDI-MSI) analyses of endoscopic biopsies from inflamed and non-inflamed segments obtained from UC patients. Our results indicated that lipid profiling of epithelial cells discriminated between healthy and UC patients. We also demonstrated that epithelial cells of the inflamed mucosa were characterized by a decrease in mono- and di-unsaturated fatty acid-containing phospholipids and higher levels of arachidonic acid-containing species, suggesting an alteration of the lipid gradients occurring concomitantly to the epithelial differentiation. This result was reinforced by the immunofluorescence analysis of EPHB2 and HPGD, markers of epithelial cell differentiation, sustaining that altered lipid profiles were at least partially due to a faulty differentiation process. Overall, our results showed that lipid profiling by MALDI-MSI faithfully conveys molecular and functional alterations associated with the inflamed epithelium, providing the foundation for a novel molecular characterization of UC patients.

RESUMEN

BACKGROUND AND AIMS: Inflammatory bowel disease (IBD) is a prevalent chronic noncurable disease associated with profound metabolic changes. The discovery of novel molecular indicators for unraveling IBD etiopathogenesis and the diagnosis and prognosis of IBD is therefore pivotal. We sought to determine the distinctive metabolic signatures from the different IBD subgroups before treatment initiation. METHODS: Serum and urine samples from newly diagnosed treatment-naïve IBD patients and age and sex-matched healthy control (HC) individuals were investigated using proton nuclear magnetic resonance spectroscopy. Metabolic differences were identified based on univariate and multivariate statistical analyses. RESULTS: A total of 137 Crohn's disease patients, 202 ulcerative colitis patients, and 338 HC individuals were included. In the IBD cohort, several distinguishable metabolites were detected within each subgroup comparison. Most of the differences revealed alterations in energy and amino acid metabolism in IBD patients, with an increased demand of the body for energy mainly through the ketone bodies. As compared with HC individuals, differences in metabolites were more marked and numerous in Crohn's disease than in ulcerative colitis patients, and in serum than in urine. In addition, clustering analysis revealed 3 distinct patient profiles with notable differences among them based on the analysis of their clinical, anthropometric, and metabolomic variables. However, relevant phenotypical differences were not found among these 3 clusters. CONCLUSIONS: This study highlights the molecular alterations present within the different subgroups of newly diagnosed treatment-naïve IBD patients. The metabolomic profile of these patients may provide further understanding of pathogenic mechanisms of IBD subgroups. Serum metabotype seemed to be especially sensitive to the onset of IBD.

RESUMEN

BACKGROUND: patient satisfaction with healthcare services provided for inflammatory bowel diseases (IBD) is essential due to high resources use. OBJECTIVES: the study aimed to describe patient satisfaction with healthcare services using the CACHE questionnaire and to assess gastroenterologist and nurse perception on patients' satisfaction. METHODS: observational multicentric prospective study in 35 Spanish hospitals. Patients included had Crohn's disease or ulcerative colitis. The study was approved by the Hospital Universitari Vall d'Hebron Ethics Committee. Scheduled study visits: baseline (patient sociodemographics and clinical data were collected), 2-4 and 6-months. Patient satisfaction with healthcare was assessed by CACHE questionnaire at each visit; it scores from 0-least satisfaction to 100-highest satisfaction.Gastroenterologists and nurses answered once an adapted questionnaire. RESULTS: participating 290 patients (54.2 % males, 41.3 years old), 62 gastroenterologists and 47 nurses. At baseline mean (SD) CACHE score was 81.7 (10.9); satisfaction with clinician care was the highest, patient information the lowest. Scores did not change across study. Gastroenterologist global score was 72.5 (9.8); Staff Care satisfaction was the highest, patient information the lowest. All scores were significantly lower than patients'. Nurses' global score was 82.2 (8.5), clinician care satisfaction was the highest, centre facilities the lowest. Scores on satisfaction with clinician care, centre facilities, and patient information scored statistically lower than patients'. No relationship was found between patients' satisfaction and patients characteristics. conclusions: IBD patients are satisfied with healthcare services provided, even though the information may be improved. Nurses' perception is similar to that of patients, physicians have a lower perception.

RESUMEN

OBJECTIVE: To assess and improve the level of implementation of the recommendations for the psychological management of patients with spondyloarthritis (SpA) and associated inflammatory bowel disease (IBD). METHODS: Qualitative study. We performed a narrative literature review to identify the recommendations for the psychological management of SpA and associated IBD and to explore their level of implementation. Based on the findings, we developed a national survey to assess: (1) current level of knowledge and implementation of the recommendations; (2) attitudes towards the recommendations; and (3) barriers and facilitators to their implementation. The results of the review and survey were discussed by a multidisciplinary group of 9 expert rheumatologists and gastroenterologists, who defined implementation strategies to increase the uptake of the recommendations. RESULTS: The review included 4 articles, 2 of them included direct recommendations on the identification and management of psychological problems in patients with SpA and IBD. None assessed the level of implementation of the recommendations in routine clinical practice. Our survey showed a great lack of awareness and implementation of the recommendations, even though psychological issues are very relevant for health professionals. Lack of time, resources, and knowledge are considered the main barriers to adherence to the recommendations. We propose several implementation strategies related to educational activities, clinical practice, and others to increase the uptake of reported recommendations. CONCLUSIONS: Further research and efforts are required to achieve behaviour changes in clinical practice to improve the identification and management of psychological problems and needs in patients with SpA and IBD.

RESUMEN

BACKGROUND: Previous studies comparing immigrant ethnic groups and native patients with IBD have yielded clinical and phenotypic differences. To date, no study has focused on the immigrant IBD population in Spain. METHODS: Prospective, observational, multicenter study comparing cohorts of IBD patients from ENEIDA-registry who were born outside Spain with a cohort of native patients. RESULTS: We included 13,524 patients (1,864 immigrant and 11,660 native). The immigrants were younger (45 ± 12 vs. 54 ± 16 years, p < 0.001), had been diagnosed younger (31 ± 12 vs. 36 ± 15 years, p < 0.001), and had a shorter disease duration (14 ± 7 vs. 18 ± 8 years, p < 0.001) than native patients. Family history of IBD (9 vs. 14%, p < 0.001) and smoking (30 vs. 40%, p < 0.001) were more frequent among native patients. The most prevalent ethnic groups among immigrants were Caucasian (41.5%), followed by Latin American (30.8%), Arab (18.3%), and Asian (6.7%). Extraintestinal manifestations, mainly musculoskeletal affections, were more frequent in immigrants (19 vs. 11%, p < 0.001). Use of biologics, mainly anti-TNF, was greater in immigrants (36 vs. 29%, p < 0.001). The risk of having extraintestinal manifestations [OR: 2.23 (1.92-2.58, p < 0.001)] and using biologics [OR: 1.13 (1.0-1.26, p = 0.042)] was independently associated with immigrant status in the multivariate analyses. CONCLUSIONS: Compared with native-born patients, first-generation-immigrant IBD patients in Spain were younger at disease onset and showed an increased risk of having extraintestinal manifestations and using biologics. Our study suggests a featured phenotype of immigrant IBD patients in Spain, and constitutes a new landmark in the epidemiological characterization of immigrant IBD populations in Southern Europe.
