Abstrakt:	Background: Iron deficiency (ID) is one of the most common manifestations of Celiac disease (CD). We aimed to determine whether ID at CD diagnosis affects tissue transglutaminase antibody (TTG) normalization rate among pediatric CD patients adhering to a gluten-free diet (GFD). Methods: We conducted a retrospective, observational cohort study that enrolled CD subjects aged 2-18y, diagnosed between Jan 2016 and Dec 2020. Demographic and laboratory data were collected at diagnosis and one year after adherence to GFD. ID was determined according to hemoglobin and ferritin levels. We compared CD subjects with and without ID at CD diagnosis in relation to TTG normalization at one year. Results: Our cohort included 118 pediatric CD subjects. At diagnosis, 61 (51.7%) of CD subjects had ID, of whom 27 (44.3%) were female, compared to 46 (80.7%) females in the non-ID group (p<0.001). Median age at CD diagnosis was 5.7y (IQR 4-8.4, range 2-14) and 7.2y (IQR 4.7-10.8, range 0.9-16), and among those with and without ID, respectively (p=0.1). After one year of adherence to GFD, TTG normalization was achieved in 38 (65.5%) and 28 (53.8%) of those with and without ID at CD diagnosis, respectively (p=0.21). However, TTG normalization was achieved in 38 (79.2%) of males compared to 42 (49.4%) of females (p=0.001). Conclusions: ID at CD diagnosis was not associated with lower rates of TTG normalization at one year among pediatric patients adhering to GFD. However, TTG normalization at one year was significantly more frequent among male subjects compared to females.
