Article Abstract

Background: Disease-modifying anti-IBD drugs such as infliximab have altered the treatment of IBD. Despite the increasing availability of disease-modifying anti-IBD drugs, many individuals with IBD still require surgical resection, and the role of disease-modifying anti-IBD drugs in delaying colectomy is limited.

Objective: To assess use patterns of disease-modifying anti-IBD drug use preceding colectomy for refractory IBD.

Design: Retrospective analysis of institutional data.

Setting: Academic tertiary medical center from 2003 to 2022.

Patients: Patients with Crohn's disease or ulcerative colitis who underwent total abdominal colectomy or proctocolectomy for medically refractory disease were included.

Main Outcome Measures: Number and type of disease-modifying anti-IBD drugs used before colectomy and use of disease-modifying anti-IBD drugs over time.

Results: A total of 487 patients met inclusion criteria. Most patients had ulcerative colitis (77.8%) and were men (57.1%), with a mean age at diagnosis of 32.1 years. Two hundred eighty patients' first disease-modifying anti-IBD drug was an anti-tumor necrosis factor agent. We found no significant difference in time from diagnosis to colectomy when comparing those who initially received an anti-tumor necrosis factor versus a non-anti-tumor necrosis agent (8.29 vs 8.86 years, p = 0.39). Linear regression demonstrated that, with each decade, patients used about 1.5 additional disease-modifying anti-IBD drugs ( p < 0.01) before surgery. The mean time between diagnosis and colectomy was 8.6 years. Accelerated failure time modeling demonstrated each additional disease-modifying anti-IBD drug was associated with a nonsignificant 5% increase in time between diagnosis and colectomy (1.05 [0.96-1.13], p = 0.25).

Limitations: Single-center, retrospective.

Conclusions: During a 20-year period, patients with IBD-associated colitis who ultimately required colectomy received increasing numbers of disease-modifying anti-IBD drugs; however, each additional disease-modifying anti-IBD drug used did not significantly delay time to colectomy, nor did initial non-anti-tumor necrosis factor agent choice. These data suggest that a subset of patients are using increasing numbers of disease-modifying anti-IBD drugs that do not afford them meaningful time in delaying colectomy. See Video Abstract .

Veinte Aos De Uso De Frmacos Modificadores De La Enfermedad Inflamatoria Intestinal Tras Una Colectoma Por Colitis Asociada A Enfermedad Inflamatoria Intestinal Refractaria: ANTECEDENTES:Los medicamentos modificadores de la enfermedad inflamatoria intestinal (DMAID, por sus siglas en inglés), como el infliximab, han cambiado el tratamiento de la enfermedad inflamatoria intestinal. A pesar de la creciente disponibilidad de estos medicamentos, muchas personas con enfermedad inflamatoria intestinal siguen necesitando una resección quirúrgica, y el papel de los medicamentos modificadores de la enfermedad inflamatoria intestinal para retrasar la colectomía es limitado.OBJETIVO:Evaluar los patrones de uso de los medicamentos modificadores de la enfermedad inflamatoria intestinal antes de la colectomía para la enfermedad inflamatoria intestinal refractaria.DISEÑO:Análisis retrospectivo de datos institucionales.ENTORNO:Centro médico terciario académico entre 2003 y 2022.PACIENTES:Pacientes con enfermedad de Crohn o colitis ulcerosa que se sometieron a una colectomía abdominal total o a una proctocolectomía por enfermedad médicamente refractaria.PRINCIPALES MEDIDAS DE RESULTADO:Número y tipo de medicamentos modificadores de la enfermedad inflamatoria intestinal utilizados antes de la colectomía y uso de medicamentos modificadores de la enfermedad inflamatoria intestinal a lo largo del tiempo.RESULTADOS:Un total de 487 pacientes cumplieron los criterios de inclusión, la mayoría de los cuales tenían colitis ulcerosa (77,8 %) y eran hombres (57,1 %), con una edad media en el momento del diagnóstico de 32,1 años. El primer medicamento modificador de la enfermedad inflamatoria intestinal que recibieron 280 pacientes fue un agente anti-TNF. No se encontraron diferencias significativas en el tiempo transcurrido desde el diagnóstico hasta la colectomía al comparar a los que recibieron inicialmente un agente antitumoral necrosis factor frente a un agente no antitumoral necrosis (8,29 años frente a 8,86 años, p = 0,39). La regresión lineal demostró que, con cada década, los pacientes utilizaban aproximadamente 1,5 medicamentos modificadores de la enfermedad inflamatoria intestinal adicionales ( p < 0,01) antes de la cirugía. El tiempo medio entre el diagnóstico y la colectomía fue de 8,6 años. El modelo de tiempo de fracaso acelerado demostró que cada medicamento modificador de la enfermedad inflamatoria intestinal adicional se asociaba con un aumento no significativo del 5 % en el tiempo entre el diagnóstico y la colectomía (1,05 [0,96-1,13], p = 0,25).LIMITACIONES:Retrospectivo, de un solo centro.CONCLUSIONES:Durante un periodo de 20 años, los pacientes con colitis asociada a enfermedad inflamatoria intestinal que finalmente requirieron colectomía recibieron un número cada vez mayor de medicamentos modificadores de la enfermedad inflamatoria intestinal; sin embargo, cada medicamento modificador de la enfermedad inflamatoria intestinal adicional utilizado no retrasó significativamente el tiempo hasta la colectomía, ni tampoco lo hizo la elección inicial de un agente no anti-TNF. Estos datos sugieren que un subgrupo de pacientes está utilizando un número cada vez mayor de medicamentos modificadores de la enfermedad inflamatoria intestinal que no les proporcionan un tiempo significativo para retrasar la colectomía.

In Latin America, the prevalence of Inflammatory Bowel Disease (IBD) has increased in recent years, creating a growing need for diagnostic tools both for its detection and for ongoing monitoring. Intestinal ultrasound (IUS) has become a well-established, non-invasive, accurate, and well-tolerated tool to evaluate IBD activity in real time-even during the same medical consultation. Available evidence supports its usefulness in accurately determining inflammatory activity and identifying associated complications.

Inflammatory bowel disease (IBD), encompassing Crohn's disease and ulcerative colitis, arises from complex interactions among genetics, immunity, environmental triggers, and, critically, the gut microbiome. Dysbiosis - marked by a loss of beneficial microbes and expansion of pro-inflammatory taxa - plays a pivotal role in disease pathogenesis. This review highlights the central role of gut microbiota in IBD and explores evidence-based nutritional interventions aimed at restoring microbial balance and immune regulation.

Background And Aims: The incidence and prevalence of inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), are increasing across Latin America. IBD has an important impact on patients' quality of life and is associated with significant healthcare resource utilization (HCRU). This study aimed to describe the more recent epidemiological characteristics and HCRU patterns of IBD in Colombia.

Frailty is a state of vulnerability characterised by a decrease in physiological reserve and the ability to respond to stress, which increases the risk of complications, adverse effects of treatments and functional decline. Assessing frailty allows the biological age of patients to be determined, beyond their chronological age, providing a more accurate picture of their health status and care needs. The proportion of older adults with IBD is increasing in parallel with the ageing of the general population, and it is estimated that in the next decade, more than a third of IBD patients will be over 60 years of age.

Objective: Real-world evidence (RWE) on vedolizumab (VDZ), an anti-lymphocyte trafficking treatment that selectively targets the α4β7/MAdCAM-1 interaction on the gut, is mostly limited to patients who are repeatedly refractory to anti-tumor necrosis factor-alpha (anti-TNF-α), and other treatments. The EVOLVE-IBERIA study assessed VDZ or anti-TNF-α as first- or second-line biologic treatment, in patients with Crohn's disease or ulcerative colitis (UC); here, we present the outcomes in patients with UC.

Patients And Methods: Medical records were retrospectively reviewed from 25 hospitals in Spain and Portugal.
