Introduction:
Inflammatory bowel disease research in Spain has expanded considerably in recent decades; however, no structured evaluation has comprehensively assessed its scientific production or its representation at major international congresses. This study aimed to provide a descriptive overview of recent Spanish contributions to clinical, translational, and basic inflammatory bowel disease research, and to analyse scientific leadership, regional distribution, methodological approaches, research topics, and gender representation.
Material And Methods:
Publications from 2020 to 2024 were systematically retrieved from PubMed and classified according to study type, research topic, methodology, journal quartile ranking, and authorship characteristics. Accepted communications presented at the European Crohn's and Colitis Organisation congresses between 2019 and 2024 were also evaluated regarding study type, presentation format, scientific leadership, gender of the last author, and regional origin.
Results:
A total of 1,361 Spanish scientific contributions were identified. Clinical research represented 61.3% (n = 834) of publications, whereas basic and translational studies accounted for 38.7% (n = 527) of the total output. 84.5% (n = 1,150) of publications were published in Quartile 1 or 2 journals, and 30.6% (n = 291) of Quartile 1 articles appeared in top-decile journals. Scientific activity was predominantly concentrated in Catalonia and Madrid. Advanced experimental methodologies were frequently employed in basic and translational research. Across congress communications, 638 abstracts were identified, with Spain contributing 8.5-12.4% of total accepted presentations (n = 80-126 abstracts annually). Women were more frequently represented in leadership roles in basic and translational research than in clinical studies.
Conclusion:
The current landscape of IBD research in Spain is characterised by sustained scientific activity, a broad spectrum of clinical, translational and basic research, and extensive international collaboration, despite marked regional differences in research productivity and persistent gender disparities in leadership.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
