Plasma iFABP concentration was significantly higher in newly diagnosed coeliac disease compared to Controls (plasma iFABP newly diagnosed coeliac disease: 2104 pg/mL [1493, 2457] vs Controls: 938 pg/mL [616, 1140], p = 0.001), and patients with established coeliac disease (plasma iFABP newly diagnosed coeliac disease: 2104 pg/mL [1493, 2457] vs established coeliac disease: 1070 pg/mL [760, 1415], p = 0.002), Fig. 2. Here, FABP2 is linked to celiac disease.
