Abstract

Background/Purpose: Burning mouth syndrome (BMS) is characterized by burning sensation of the oral mucosa in the absence of clinically apparent oral mucosal alterations. This study evaluated the anemia, hematinic deficiencies, hyperhomocysteinemia, and serum gastric parietal cell antibody (GPCA) positivity in 884 BMS patients. Methods: The blood hemoglobin (Hb) and serum iron, vitamin B12, folic acid, homocysteine, GPCA levels in 884 BMS patients were measured and compared with the corresponding levels in 442 age- and sex-matched healthy control subjects. Results: We found that 175 (19.8%), 143 (16.2%), 42 (4.8%), 20 (2.3%), 170 (19.2%), and 109 (12.3%) BMS patients had blood Hb, serum iron, vitamin B12, and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity, respectively. Moreover, 884 BMS patients had significantly higher frequencies of blood Hb and serum iron, vitamin B12, and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity than 442 healthy control subjects (all P-values < 0.005). Of 175 anemic BMS patients, 95 had normocytic anemia, 27 had thalassemia trait-induced anemia, 21 had iron deficiency anemia, 15 had pernicious anemia, 15 had macrocytic anemia other than pernicious anemia, and 2 had microcytic anemia other than iron deficiency anemia and thalassemia trait-induced anemia. Burning sensation of oral mucosa (100.0%), dry mouth (48.1%), numbness of oral mucosa (30.7%), and dysfunction of taste (16.7%) were the four common symptoms in 884 BMS patients. Conclusion: BMS patients have significantly higher frequencies of blood Hb and serum iron, vitamin B12, and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity than healthy control subjects.
