Figure 1: Increased levels of IFABP in serum samples of active CD. IFABP serum levels (pg/mL) were assessed by commercial quantitative ELISA. Serum samples from adults and pediatric patients were plotted together since no differences between both populations were observed. Serum samples from controls (), untreated CD patients (), CD patients on gluten-free diet (GFD) (), and intestinal bowel disease (IBD) patients () were analyzed. Values are expressed as mean ± standard deviation (s.d.) of the mean. Representative experiments were analyzed statistically using the Mann-Whitney test. (A) ; (B) ; (C) .
