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.

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.

Environmental Exposure to Trace Elements and Heavy Metals Preceding the Clinical Onset of Inflammatory Bowel Disease.

Background: The immune dysregulation underlying inflammatory bowel disease (IBD) can start years before the diagnosis, but the role of triggering factors and environmental exposures during this period is still uncertain. Methods: This single-center case-control study included asymptomatic subjects with an incidental diagnosis of IBD during the colorectal cancer screening program. Twenty-two minerals and 17 metals were determined at diagnosis in hair samples and compared 1:2 to healthy controls. Results: Six patients with preclinical IBD (3 ulcerative colitis, 67% left-sided; 3 Crohn's disease, 100% ileal, 67% inflammatory behavior) and 13 healthy non-IBD controls were included. No relevant occupational exposures were identified. We found statistically significant higher levels of sodium, potassium, and boron among cases compared to controls; while lower levels of zinc, uranium, copper, and germanium were observed. Conclusions: A range of environmental exposures can be identified during the preclinical phase of IBD, but their relationship with the symptomatic onset and disease progression should be further explored.

Therapeutic drug monitoring in inflammatory bowel diseases. Position statement of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis. / Monitorización terapéutica de los fármacos biológicos en la enfermedad inflamatoria intestinal. Documento de Posicionamiento del Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa (GETECCU).

The treatment of inflammatory bowel disease has undergone a significant transformation following the introduction of biologic drugs. Thanks to these drugs, treatment goals have evolved from clinical response and remission to more ambitious objectives, such as endoscopic or radiologic remission. However, even though biologics are highly effective, a significant percentage of patients will not achieve an initial response or may lose it over time. We know that there is a direct relationship between the trough concentrations of the biologic and its therapeutic efficacy, with more demanding therapeutic goals requiring higher drug levels, and inadequate exposure being common. Therapeutic drug monitoring of biologic medications, along with pharmacokinetic models, provides us with the possibility of offering a personalized approach to treatment for patients with IBD. Over the past few years, relevant information has accumulated regarding its utility during or after induction, as well as in the maintenance of biologic treatment, in reactive or proactive strategies, and prior to withdrawal or treatment de-escalation. The aim of this document is to establish recommendations regarding the utility of therapeutic drug monitoring of biologics in patients with inflammatory bowel disease, in different clinical practice scenarios, and to identify areas where its utility is evident, promising, or controversial.

Clinical and treatment outcomes of a second subcutaneous or intravenous anti-TNF in patients with ulcerative colitis treated with two consecutive anti-TNF agents: data from the ENEIDA registry.

Background: Infliximab seems to be the most efficacious of the three available anti-TNF agents for ulcerative colitis (UC) but little is known when it is used as the second anti-TNF. Objectives: To compare the clinical and treatment outcomes of a second subcutaneous or intravenous anti-TNF in UC patients. Design: Retrospective observational study. Methods: Patients from the ENEIDA registry treated consecutively with infliximab and a subcutaneous anti-TNF (or vice versa), naïve to other biological agents, were identified and grouped according to the administration route of the first anti-TNF into IVi (intravenous initially) or SCi (subcutaneous initially). Results: Overall, 473 UC patients were included (330 IVi and 143 SCi). Clinical response at week 14 was 42.7% and 48.3% in the IVi and SCi groups (non-statistically significant), respectively. Clinical remission rates at week 52 were 32.8% and 31.4% in the IVi and SCi groups (nonsignificant differences), respectively. A propensity-matched score analysis showed a higher clinical response rate at week 14 in the SCi group and higher treatment persistence in the IVi group. Regarding long-term outcomes, dose escalation and discontinuation due to the primary failure of the first anti-TNF and more severe disease activity at the beginning of the second anti-TNF were inversely associated with clinical remission. Conclusion: The use of a second anti-TNF for UC seems to be reasonable in terms of efficacy, although it is particularly reduced in the case of the primary failure of the first anti-TNF. Whether the second anti-TNF is infliximab or subcutaneous does not seem to affect efficacy.

Position statement of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis on sexuality and inflammatory bowel disease. / Documento de posicionamiento. Recomendaciones del Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa sobre sexualidad y enfermedad inflamatoria intestinal.

It is widely acknowledged that inflammatory bowel disease (IBD) is associated with a high prevalence of sexual dysfunction (SD). However, there is a notable paucity of specific literature in this field. This lack of information impacts various aspects, including the understanding and comprehensive care of SD in the context of IBD. Furthermore, patients themselves express a lack of necessary attention in this area within the treatment of their disease, thus creating an unmet need in terms of their well-being. The aim of this position statement by the Spanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU) is to provide a review on the most relevant aspects and potential areas of improvement in the detection, assessment, and management of SD in patients with IBD and to integrate the approach to sexual health into our clinical practice. Recommendations are established based on available scientific evidence and expert opinion. The development of these recommendations by GETECCU has been carried out through a collaborative multidisciplinary approach involving gastroenterologists, gynecologists, urologists, surgeons, nurses, psychologists, sexologists, and, of course, patients with IBD.

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.

Real-world long-term effectiveness of ustekinumab in ulcerative colitis: results from a spanish open-label cohort.

OBJECTIVE: Ustekinumab was recently approved for the treatment of moderate-to-severe ulcerative colitis (UC). Although data from the UNIFI clinical trial are encouraging, real-world data assessing effectiveness and safety are scarce. The aim of this study was to assess the effectiveness, safety and pharmacokinetics of ustekinumab in a large cohort of refractory UC patients. METHODS: Multicenter observational study of UC patients who received ustekinumab for active disease. The Partial Mayo Score (PMS), endoscopic activity, C-reactive protein (CRP) and faecal calprotectin (FC) were recorded at baseline and at different time points. Demographic and clinical data, adverse events (AEs) and surgeries were documented. RESULTS: A total of 108 patients were analyzed from 4 referral Spanish hospitals. The clinical remission rates were 59%, 56.5%, 57% and 69% of patients at weeks 8, 16, 24 and 52, respectively. Normalization of FC was achieved in 39.6%, 41% and 51% at weeks 8, 24 and 52, respectively. CRP normalization was observed in 79%, 75% and 76.5% of patients at weeks 8, 24 and 52, respectively. Fewer previous anti-TNF agents and loss of response to anti-TNF were associated with clinical response and normalization of FC, respectively. AEs were observed in 5 patients, and 9 underwent colectomy. Ustekinumab persistence rates were 91%, 83% and 81% at 24, 48 and 96 weeks, respectively. CONCLUSIONS: Ustekinumab demonstrated, in the real-world setting, long-term effectiveness and a favorable safety profile in a cohort of refractory UC patients.

Comparative Study of the Effectiveness of Vedolizumab Versus Ustekinumab After Anti-TNF Failure in Crohn's Disease (Versus-CD): Data from the ENEIDA Registry.

BACKGROUND: Both vedolizumab and ustekinumab are approved for the management of Crohn's disease [CD]. Data on which one would be the most beneficial option when anti-tumour necrosis factor [anti-TNF] agents fail are limited. AIMS: To compare the durability, effectiveness, and safety of vedolizumab and ustekinumab after anti-TNF failure or intolerance in CD. METHODS: CD patients from the ENEIDA registry who received vedolizumab or ustekinumab after anti-TNF failure or intolerance were included. Durability and effectiveness were evaluated in both the short and the long term. Effectiveness was defined according to the Harvey-Bradshaw index [HBI]. The safety profile was compared between the two treatments. The propensity score was calculated by the inverse probability weighting method to balance confounder factors. RESULTS: A total of 835 patients from 30 centres were included, 207 treated with vedolizumab and 628 with ustekinumab. Dose intensification was performed in 295 patients. Vedolizumab [vs ustekinumab] was associated with a higher risk of treatment discontinuation (hazard ratio [HR] 2.55, 95% confidence interval [CI]: 2.02-3.21), adjusted by corticosteroids at baseline [HR 1.27; 95% CI: 1.00-1.62], moderate-severe activity in HBI [HR 1.79; 95% CI: 1.20-2.48], and high levels of C-reactive protein at baseline [HR 1.06; 95% CI: 1.02-1.10]. The inverse probability weighting method confirmed these results. Clinical response, remission, and corticosteroid-free clinical remission were higher with ustekinumab than with vedolizumab. Both drugs had a low risk of adverse events with no differences between them. CONCLUSION: In CD patients who have failed anti-TNF agents, ustekinumab seems to be superior to vedolizumab in terms of durability and effectiveness in clinical practice. The safety profile is good and similar for both treatments.

Serum and Urine Metabolomic Profiling of Newly Diagnosed Treatment-Naïve Inflammatory Bowel Disease Patients.

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.

Is Occupation a Risk Factor for Developing Inflammatory Bowel Disease? A Case-Control Study.

Background and aims: The role of occupation is uncertain in the onset of inflammatory bowel diseases. The aim of this study is to identify if there is a role of occupation in these diseases. Materials and methods: A case-control study with incident cases with inflammatory bowel diseases was designed. Cases and controls were recruited simultaneously and controls followed a sex and age frequency matching with cases. A detailed questionnaire was completed by all the participants. To analyze the results, a logistic regression was used. A subgroup analysis was performed for each inflammatory bowel disease. Results: A total of 141 patients with incident inflammatory bowel disease (80 ulcerative colitis, 55 Crohn's disease, and 6 unclassified colitis) and 114 controls were included. There were no statistically significant differences in type of work, working hours, contact with animals, or physical activity at work between inflammatory bowel disease patients and controls. After stratifying results according to type of IBD, there were no statistically significant differences either. Conclusions: There seems to be no risk for inflammatory bowel disease onset regarding the type of work, working hours, contact with animals, or sedentariness.

Enhancing Therapeutic Drug Monitoring in Inflammatory Bowel Disease: A Comparative Analysis of Rapid Point-of-Care Infliximab, Adalimumab and Anti-Drug Antibodies' Determination against ELISA.

The introduction of point-of-care (POC) assays into clinical practice in patients with inflammatory disease enables on-demand therapeutic decision making. The aim of this study was to compare the POC test Quantum blue (Bühlmann Laboratories) for infliximab (IFX), adalimumab (ADL), and its anti-drug antibodies with the traditional ELISA assay (Promonitor). A total of 200 serum samples were analyzed. Samples were classified into the following three different groups; sub-therapeutic range (IFX < 3 µg/mL and ADL < 5 µg/mL); therapeutic range (IFX: 3-7 µg/mL and ADL: 5-12 µg/mL) and supra-therapeutic range (IFX levels > 7 µg/mL and ADL levels > 12 µg/mL). Significant higher values were measured using the POC test (p < 0.001) for IFX results but no differences in ADL trough levels were observed (p = 0.3101). Spearman's correlation indicated a good correlation between the two assays (rs = 0.88 for ADL and rs = 0.93 for IFX), and McNemar's test revealed significant differences (p = 0.016) when classifying IFX samples between therapeutic and supra-therapeutic ranges but no significant differences were found among the other ranges for either IFX or ADL. These results show that we should be cautious when using these rapid measurement methods, and new targets should probably be defined for IFX when using this new analytical method.

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.

Initial management of intraabdominal abscesses and preventive strategies for abscess recurrence in penetrating Crohn's disease: a national multicenter study based on ENEIDA registry.

INTRODUCTION: Intra-abdominal abscesses complicating Crohn's disease (CD) are a challenging situation. Their management, during the hospitalization and after resolution, is still unclear. METHODS: Adult patients with CD complicated with intraabdominal abscess who required hospitalization were included from the prospectively maintained ENEIDA registry from GETECCU. Initial strategy effectiveness and safety to resolve abscess was assessed. Survival analysis was performed to evaluate recurrence risk. Predictive factors associated with resolution were evaluated by multivariate regression and predictive factors associated with recurrence were assessed by Cox regression. RESULTS: 520 patients from 37 Spanish hospitals were included; 322 (63%) were initially treated with antibiotics alone, 128 (26%) with percutaneous drainage, and 54 (17%) with surgical drainage. The size of the abscess was critical to the effectiveness of each treatment. In abscesses < 30mm, the antibiotic was as effective as percutaneous or surgical drainage. However, in larger abscesses, percutaneous or surgical drainage was superior. In abscesses > 50mm, surgery was superior to percutaneous drainage, although it was associated with a higher complication rate. After abscess resolution, luminal resection was associated with a lower 1-year abscess recurrence risk (HR 0.43, 95% CI 0.24-0.76). However, those patients who initiated anti-TNF therapy had a similar recurrence risk whether luminal resection had been performed. CONCLUSIONS: Small abscesses (<30mm) can be managed with antibiotics alone, while larger ones require drainage. Percutaneous drainage will be effective and safer than surgery in many cases. After discharge, anti-TNF therapy reduces abscess recurrence risk in a similar way to bowel resection.

[Association between vitamin D and inflammatory bowel diseases]. / Asociación entre la vitamina D y las enfermedades inflamatorias intestinales.

Vitamin D is a hormone known for a long time, for its effects on bone health and the regulation of phosphorus and calcium metabolism. Since the discovery of receptors for this molecule in a large number of cells in the body, the field has been opened for the study of its effects on the immune system. Its relationships with the cells of the immune system, genes, and microbiota cause great interest in relation to immune-mediated diseases. Many data indicates that this vitamin has preventive, modulating and controlling effects of the adverse effects of Inflammatory Bowel Diseases (IBD) on bone health, although it is difficult to definitively demonstrate causality. In this review, we try to summarize the current situation and controversial issues in this interesting field, focusing on inflammatory bowel diseases.

Encuesta Sociedad Española de Médicos de Atención Primaria (SEMERGEN) y Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa (GETECCU) sobre el manejo de pacientes con enfermedad inflamatoria intestinal / Spanish Society of Primary Care Physicians (SEMERGEN) and Spanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU) survey on the management of patients with inflammatory bowel disease

Introducción: La colaboración entre Atención Primaria (AP) y Gastroenterología en la enfermedad inflamatoria intestinal (EII) es crucial para ofrecer una atención médica de alta calidad. El objetivo del presente estudio es analizar, en el ámbito nacional, la relación entre AP y los gastroenterólogos con el objetivo de conocer los aspectos de mejora en el manejo de pacientes con EII y cómo poder implementarlos, para así desarrollar posteriormente propuestas y proyectos concretos entre SEMERGEN y GETECCU. Metodología: Estudio descriptivo, observacional y transversal, realizado mediante cuestionario online anónimo entre octubre de 2021 y marzo de 2022. Resultados: Se recopilaron un total de 157 encuestas de Gastroenterología y 222 de AP. El 43,8% y el 34,3% de los gastroenterólogos y médicos de familia, respectivamente, consideraron tener una buena relación. El grado de conocimiento de los médicos de familia sobre diferentes aspectos de la EII (puntuado sobre 10) fue: aspectos clínicos 6,67±1,48, diagnósticos 6,47±1,46, terapéuticos 5,63±1,51, de seguimiento 5,53±1,68 y complicaciones 6,05±1,54. La percepción del apoyo y soporte entre ambas unidades no superó el 4,5 en una escala de 0 a 10 en ninguna de las encuestas. Las propuestas de mejora más votadas fueron: mayor coordinación entre especialistas, implantación de unidades de EII y colaboración de enfermería. Conclusión: Existen deficiencias en la relación entre AP y Gastroenterología con especial dedicación a la EII que requiere de los esfuerzos de las sociedades científicas que los representan para una mayor coordinación, con elaboración de protocolos conjuntos y medios de comunicación ágiles, rápidos y efectivos.

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.

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.

[Health-related quality of life by IBDQ-32 in colombian patients with inflammatory bowel disease in remission: A cross-sectional study]. / Calidad de vida relacionada con la salud por IBDQ-32 en pacientes colombianos con enfermedad inflamatoria intestinal en remisión: Un estudio de corte transversal.

In Colombia there are no data about perception of quality of life (QoL) in inflammatory bowel disease (IBD). The aim of this study was to determine the perception of QoL by means of the IBDQ-32 questionnaire in patients with IBD from a sample of patients from different referral centers. We carried out a cross-sectional study in adults with IBD in clinical remission, in outpatient follow-up, in 3 institutions in different cities, between June 2022 and November 2022, eligible subjects were identified, information was collected on different dates, about socio-demographic and clinical aspects, and the IBDQ-32 questionnaire was evaluated on one occasion. Descriptive and analytical analysis of the variables evaluated was performed. 80 patients, 70% women, mean age 38.5(range 18-72; SD 13.25) years. 67.5% ulcerative colitis (UC), 32.5% Crohn's disease (CD). Moderate QoL involvement (median 150 points, interquartile range118.3-181.5) was found in IBD, in UC median 151 (interquartile range120-174.75) points, while in CD 133 (interquartile range106.25-186.25) points. There was greater involvement in the systemic domain, with median 21 (interquartile range 15.8-27) points, and 18.5 (interquartile range 12.8-25.3) points, for UC and CD, respectively. The least affected corresponded to the digestive domain and social function, in median UC 48.5 (interquartile range 40-58.3), and 27(interquartile range 20.8-33); in median CD 43 (interquartile range 35.5-61.75) and 24.5(interquartile range 18-32.5), respectively. No statistically significant differences were found. This study provides unique information about QoL of patients with IBD in Colombia. It is necessary to continue reinforcing the accompaniment, support, and education of patients with IBD.
