Coeliac disease has long been a challenging condition to diagnose, requiring patients to undergo invasive procedures that often involve long hospital waiting lists. However, a groundbreaking study led by Associate Professor Jason Tye Din and his PhD student Olivia Moscatelli, promises to revolutionise the way coeliac disease is diagnosed with a novel blood-based test. This new approach, developed over decades of research, aims to simplify diagnosis and improve patient outcomes.
The New Diagnostic Test: A Game Changer
The new diagnostic test is based on detecting an immune response to gluten in the blood, specifically focusing on a cytokine called Interleukin 2 (IL-2). This marker has been found to spike in coeliac patients shortly after gluten ingestion, providing a clear and rapid diagnostic signal. Unlike traditional methods, this test does not require a lengthy gluten challenge, making the diagnostic process less burdensome and more accessible.
Potential Impact and Benefits
This innovative test offers several advantages over existing diagnostic methods:
- Non-invasive: may eliminate the need for a gastroscopy, making the diagnosis quicker and less invasive for patients.
- Convenience: Can be performed with a simple blood test, without the need for a lengthy gluten challenge.
- Speed and Efficiency: Delivers results quickly, without the need for specialist lab technicians
- Accuracy: While the IL-2 test boasts sensitivity and specificity levels comparable to existing coeliac serology, its distinct advantage lies in its ability to accurately function even when individuals are adhering to a gluten-free diet.
Challenges and Future Directions
Despite the remarkable results, more work is still needed, including fine-tuning the test for different genetic sub-types and testing in children. Collaborations with international research groups are crucial to gather global data and validate the test across diverse populations.
Collaborative Efforts and Global Interest
The test has garnered extensive interest from medical and pharmaceutical communities worldwide, indicating a strong potential for widespread adoption. The importance of collaboration, including international partnerships, in advancing coeliac disease research cannot be overstated.
Looking Forward
This development not only holds the promise of changing how coeliac disease is diagnosed, but also serves as a beacon of hope for those living with the condition. With the pharmaceutical industry already utilising this technology to monitor the immune response to potential therapeutics, clinical trials can be more cost-effective and efficient. With ongoing support from Coeliac Australia and its members, a ‘cure’ for coeliac disease could soon be on the horizon.
Meet the researcher – Jason Tye-Din
Associate Professor Jason Tye-Din’s path to becoming a leading figure in coeliac disease research began during his early days as a junior doctor when he encountered a patient with the condition. Struck by the lack of comprehensive treatment and follow-up options, he felt a personal and professional drive to seek better solutions. His interest was particularly piqued due to his own experience with a food-related disease—peanut allergy—which provided him with a unique empathy and understanding of the challenges faced by individuals with dietary restrictions.
The turning point in Tye-Din’s career came when he met his future PhD supervisor, Dr Bob Anderson, who had recently returned from Oxford after conducting seminal research on coeliac disease. This meeting coincided with an opportunity to join Dr Anderson’s newly-formed coeliac research lab at the Walter and Eliza Hall Institute (WEHI). Motivated by a combination of personal interest and the clear need for improved patient care, Tye-Din decided to pursue a career in coeliac disease research.
Transitioning from clinical practice to research was a significant leap of faith for Tye-Din. Leaving the familiarity of patient consultations for the uncertainty of lab work was daunting, but the potential to make a real difference in the lives of patients with coeliac disease was too compelling to ignore. As he began to generate promising data, the rewards of research—discovering new knowledge and applying it in ways that directly benefited patients—solidified his commitment to this challenging but fulfilling path. This journey of discovery has not only fuelled his passion for translational research, but has also inspired a broader vision of – perhaps one day – preventing coeliac disease before it starts.
