FABP2 and celiac disease: In urine samples, iFABP levels did not differ significantly between patients newly diagnosed with coeliac disease and Controls (urinary iFABP Controls: 50.9 pg/mg [26.6, 108.6] vs newly diagnosed coeliac disease: 25.6 pg/mg [0.0, 80.0], p = 0.904) and its concentration did not change following GFD recommendation either at 6 or 12 months (urinary iFABP at coeliac disease diagnosis: 26 pg/mg [0, 80] vs 6mo GFD: 27 pg/mg [0, 138] p = 0.40; coeliac disease diagnosis vs 12mo GFD: 8 pg/mg [2, 92], p = 0.51).
