Overview of Celiac Disease and the Role of Biomarkers
Autoimmune responses to gluten affect millions globally, with coeliac disease representing one of the most prevalent yet underdiagnosed conditions. When gluten triggers immune activity, the small intestinal lining undergoes characteristic damage, including flattened villi and increased intraepithelial lymphocytes. Traditional diagnosis combines blood tests for specific antibodies with endoscopic biopsies, but these invasive procedures delay care for 40% of patients according to 2023 clinical data.
Emerging biomarkers now address critical gaps in detection. Researchers recently identified serum markers correlating with villous height-to-crypt depth ratios, enabling noninvasive monitoring of mucosal healing. A 2024 Creative Commons-licensed study demonstrated how HLA tetramer assays achieve 89% accuracy in distinguishing refractory subtypes (RCD1 vs. RCD2) through peripheral blood analysis alone.
These advances transform diagnostic pathways by:
- Reducing reliance on invasive tissue sampling
- Enabling real-time tracking of dietary intervention impacts
- Supporting personalized treatment plans through subtype differentiation
