Evaluation of adropin, fibroblast growth factor-1 (FGF-1), and Toll-like receptor-1 (TLR1) biomarkers in patients with inflammatory bowel disease: gene expression of TNF-α as a marker of disease severity

Inflammatory bowel disease (IBD) is a chronic relapsing inflammatory disorder of unknown etiology and unpredictable course. The aim of the work was to assess the levels of adropin, fibroblast growth factor-1 (FGF-1), and Toll-like receptor-1 (TLR1) biomarkers in IBD patients compared to controls and evaluate the gene expression of TNF-α as a marker of disease severity. Adropin, fasting serum FGF-1 levels, TLR1, and TNF-α were measured in 60 IBD patients. They were also compared with 58 healthy controls matching age and gender. Moreover, the blood cells cDNA copy number of TNF-α were determined as a marker of severity. Adropin and TLR1 levels were significantly lower in patients than controls. FGF-1 was reduced but not statistically significant. The expression of TNF-α gene in the IBD patients was significantly increased (42
