Abstract :Purpose: Non-invasive tests used in the screening and follow-up of celiac disease insert ignore into journalissuearticles values(CD); are currently below expectations because they show false negatives/positives and are not always correlated with duodenal histology. We aimed to investigate the predictive value of intestinal free fatty acid binding protein insert ignore into journalissuearticles values(FABP-I); which can easily be released into the circulation in the presence of enterocyte damage in a short time in CD. Methods: This study included 59 patients with CD who were not on gluten free diet insert ignore into journalissuearticles values(GFD);insert ignore into journalissuearticles values(n=24); and who were on GFDinsert ignore into journalissuearticles values(n=35); and 52 healthy controls. Demographic variables, complete blood count, ferritin, vitamin D, calcium, phosphorus, vitamin B12, prothrombin time, INR, and serum FABP-I levels were recorded for all groups. Results: There was no difference between the groups in terms of complete blood count, ferritin, calcium, phosphorus, vitamin B12, prothrombin time and INR insert ignore into journalissuearticles values(all p>0.05);. Mean serum FABP-I was determined as 499.2±33.3 ng/L for patients with CD who were not on GFD and as 487.7±48.0 ng/L for who were on GFD, and these values were significantly higher when compared to the healthy controls 432.2±63.8 ng/Linsert ignore into journalissuearticles values(p<0.001);. The sensitivity, specificity, positive predictive value, and negative predictive value of FABP-I for a cut-off value of 456.8 ng/L were 84.7%, 69.2%, 10.2% and 61.5%, respectivelyinsert ignore into journalissuearticles values(AUC=0.785);. Conclusion: This study has shown that FABP-I can serve as a non-invasive predictive marker for CD diagnosis. Overlooked diagnosis in serology-negative patients and false serology positivity for reasons other than CD will be prevented with its use in clinical practice since FABP-I directly reflects intestinal damage.
