In this study, serum selenium levels in patients with Crohn's disease (CD) and ulcerative colitis (UC) were evaluated to identify potential predictive markers of disease activity. Conducted in 100 inflammatory bowel disease (IBD) patients (54 CD, 46 UC) and 100 healthy controls, this research provides novel insights through focusing on the regional selenium status of people with IBD in the Polish population, a demographic with limited existing data.
Selenium concentrations were measured using inductively coupled plasma mass spectrometry (ICP-MS).
Significantly lower levels of selenium were observed in CD (64.79 µg/L ± 12.15 µg/L) and UC (68.61 µg/L ± 11.43 µg/L) patients when compared with the controls (90.52 ± 12.00 µg/L,
< 0.0001). Regression analysis identified leukocyte and erythrocyte counts and bilirubin as significant predictors of selenium levels in UC patients, while no significant predictors were found for CD.
The findings suggest that selenium deficiency is linked to IBD and may serve as a non-invasive biomarker for disease severity, particularly in UC. This practical approach offers a potential alternative to invasive procedures such as endoscopy for monitoring disease progression. However, further research is needed to confirm these findings in larger populations and explore the therapeutic role of selenium supplementation in IBD management.
