I-FABP concentrations did not differ significantly between H. Pylori positive (34.3%, 11/32) and negative (68.7%, 22/32) control patients (as determined by histology) regardless of the presence of gastritis (median: HP+ 271.6 pg/mL versus HP− 365.4 pg/mL; P = 0.17). Here, FABP2 is linked to gastritis.
