Khalifa University in the United Arab Emirates is playing a central role in a major national research initiative examining the rising incidence of inflammatory bowel disease across the country. The UAE Epi-IBD Study represents a collaborative effort to understand the clinical burden, phenotypes, and potential drivers of Crohn’s disease and ulcerative colitis in the local population.

Recent findings from the initiative highlight a dramatic increase in diagnoses over the past two decades. Data from a leading tertiary centre show nearly a 13-fold rise in new IBD cases among Arab patients between 2002 and 2024. This surge underscores the urgent need for improved diagnostic pathways and targeted research into environmental, genetic, and microbiome factors specific to the region.

Understanding the Growing IBD Challenge in the UAE

Inflammatory bowel disease encompasses two main conditions: Crohn’s disease, which can affect any part of the digestive tract, and ulcerative colitis, which is limited to the colon and rectum. Both are chronic inflammatory conditions with no known cure, though early intervention can significantly improve patient outcomes. The UAE Epi-IBD Study builds on existing consensus guidelines developed by the Emirates Gastroenterology and Hepatology Society to refine diagnostic and management approaches.

The two-decade analysis reveals not only higher diagnosis rates but also shifts in disease severity and phenotypes. Researchers note a predominance of Crohn’s disease in paediatric cases, often presenting with complex features such as perianal involvement. These patterns differ from some global cohorts and highlight the value of locally generated data for tailoring care.

Khalifa University’s Contribution to Multi-Omics Research

Khalifa University researchers are integrating multi-omics approaches within the UAE Epi-IBD framework. This includes genomics, proteomics, and microbiome analysis to uncover why IBD rates are climbing in the Emirati and broader Arab population. By combining clinical records with advanced molecular profiling, the team aims to identify biomarkers that could support faster, more accurate diagnosis.

Early detection remains a priority because delays in diagnosis can lead to complications requiring surgery or advanced therapies. The study’s longitudinal design allows tracking of disease progression from initial presentation, providing insights that could inform streamlined diagnostic protocols at UAE hospitals and clinics.

Key Findings from the Foundational Publication

The first major output from the UAE Epi-IBD collaboration appeared in Frontline Gastroenterology. It documents the pronounced rise in IBD incidence and provides the most comprehensive dataset on diagnoses and phenotypes in the UAE to date. Arab patients showed particularly sharp increases, prompting further investigation into lifestyle, dietary, and environmental changes over the study period.

Paediatric data within the same programme confirm an acceleration in childhood-onset cases. This trend carries implications for university-affiliated paediatric gastroenterology programmes and long-term health planning in the Emirates.

Implications for Higher Education and Research Training

The UAE Epi-IBD Study offers valuable opportunities for PhD candidates and postdoctoral researchers at Khalifa University and partner institutions. Projects span epidemiology, bioinformatics, and clinical translation, aligning with national priorities for knowledge-based economic development.

University administrators note that such large-scale, multi-institutional research strengthens the UAE’s position in global health sciences. It also creates pathways for Emirati scholars to lead internationally recognised work while addressing local health challenges.

Collaborative Network and Future Directions

The initiative draws on partnerships including Khalifa University, PureHealth, and international collaborators such as the University of Birmingham. This network supports data sharing, advanced analytics, and capacity building across the Emirates.

Future phases will expand environmental monitoring and longitudinal follow-up to refine risk models. Researchers anticipate that insights from the study could contribute to national screening recommendations and faster referral pathways for suspected IBD cases.

Broader Context for UAE Healthcare and Academia

The rising IBD burden intersects with broader healthcare transformation goals in the United Arab Emirates. Universities are increasingly positioned as hubs for translational research that directly informs clinical practice. Khalifa University’s involvement exemplifies how higher-education institutions contribute to evidence-based policy and improved patient care.

Stakeholders across the sector emphasise the importance of sustained funding and international collaboration to maintain momentum. The Epi-IBD programme demonstrates the potential for UAE-led research to influence regional and global understanding of chronic digestive diseases.
