Celiac disease and hematological abnormalities in children with recurrent aphthous stomatitis

Background Recurrent aphthous stomatitis (RAS) is one of the most common diseases of the oral mucosa and may be related to vitamin deficiencies or systemic diseases such as celiac disease (CD). The aim of this study was to investigate the frequency of hematinic deficiency and CD in children with RAS. Methods The medical records of patients diagnosed with RAS were reviewed for the presence of hematinic deficiencies (hemoglobin, mean corpuscular volume, ferritin, vitamin B-12, folic acid), and CD. The study group included 108 children with RAS and 57 healthy children who were evaluated for hematological abnormalities in routine evaluation. Results The frequency of a family history of RAS was significantly higher in the RAS group compared to the control group (34.2% vs 7%, respectively;P < 0.001). A hematological abnormality was detected in 32.4% of the RAS group and 10.5% of the control group (P = 0.02). The prevalence of iron deficiency anemia was significantly higher in the RAS group (P = 0.037). Three (2.7%) patients with RAS were diagnosed with CD, which is a significantly higher frequency than that observed in healthy children in Turkey (P < 0.01; OR 6.03, 95% CI [2.37, 4.56]). These children had mild malnutrition, iron deficiency, and iron deficiency anemia. Conclusions Children with RAS should be evaluated for nutritional status and hematological indices, and in the case of hematological abnormalities and malnutrition screening for CD should be considered.
