Anti-gastric parietal cell antibody (GPCA), anti-thyroglobulin antibody (TGA), and anti-thyroid microsomal antibody (TMA) have not yet been reported in patients with recurrent aphthous stomatitis (RAS). This study mainly assessed the frequencies of the presence of serum GPCA, TGA, and TMA in different types of RAS patients.MethodsSerum GPCA, TGA, and TMA levels were measured in 355 RAS patients of different subtypes and in 355 age- and sex-matched healthy control individuals.ResultsWe found that 13.0%, 19.4%, and 19.7% of 355 RAS patients, 16.7%, 23.3%, and 21.7% of 60 major-typed RAS patients, 12.2%, 18.6%, and 19.3% of 295 minor-typed RAS patients, 18.1%, 20.0%, and 21.9% of 160 atrophic glossitis-positive RAS (AG+/RAS) patients, and 8.7%, 19.0%, and 17.9% of 195 AG-negative RAS (AG–/RAS) patients had the presence of GPCA, TGA, and TMA in their sera, respectively. RAS, major-typed RAS, minor-typed RAS, AG+/RAS, and AG–/RAS patients all had a significantly higher frequency of GPCA, TGA, or TMA positivity than healthy control individuals (all p < 0.001). Of 65 TGA/TMA-positive RAS patients whose serum thyroid-stimulating hormone (TSH) levels were measured, 76.9%, 12.3%, and 10.8% of these TGA/TMA-positive RAS patients had normal, lower, and higher serum TSH levels, respectively.ConclusionWe conclude that approximately one-third RAS patients may have GPCA/TGA/TMA positivity in their sera. Because some GPCA-positive patients may develop pernicious anemia, autoimmune atrophic gastritis, and gastric carcinoma, and some TGA/TMA-positive patients may have thyroid dysfunction such as hyperthyroidism and hypothyroidism, these patients should be referred to doctors for further management.
