Abstract

Background/purpose: Our previous study found that 143 of 884 burning mouth syndrome (BMS) patients have iron deficiency (ID). This study assessed whether all BMS patients with ID (so-called ID/BMS patients) had iron deficiency anemia (IDA) and evaluated whether the ID/BMS patients had significantly higher frequencies of anemia, hematinic deficiencies, hyperhomocysteinemia, and serum gastric parietal cell antibody (GPCA) positivity than healthy control subjects. Materials and methods: The blood hemoglobin (Hb) and serum iron, vitamin B12, folic acid, homocysteine, and GPCA levels in 143 ID/BMS patients and 442 healthy control subjects were measured and compared. Results: We found that 143 ID/BMS patients had significantly lower mean blood Hb and serum iron, vitamin B12, folic acid levels as well as significantly higher mean serum homocysteine level than healthy control subjects (all P-values < 0.01). Moreover, 143 ID/BMS patients had significantly higher frequencies of blood Hb (55.9%) and serum iron (100.0%), vitamin B12 (7.7%), and folic acid (2.1%) deficiencies, hyperhomocysteinemia (27.3%), and serum GPCA positivity (12.6%) than 442 healthy control subjects (all P-values < 0.001). Furthermore, of 80 anemic ID/BMS patients, 5 (6.3%) had pernicious anemia, 5 (6.3%) had macrocytic anemia other than pernicious anemia, 42 (52.5%) had normocytic anemia, 21 (26.3%) had IDA, and 7 (8.8%) had thalassemia trait-induced anemia. Conclusion: ID/BMS patients had significantly higher frequencies of blood Hb and serum iron, vitamin B12, and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity than healthy control subjects. Normocytic anemia is the most common type of anemia in ID/BMS patients.
