Anemia, hematinic deficiencies, and hyperhomocysteinemia in younger and older burning mouth syndrome patients

Burning measure for burning mouth syndrome: a systematic review

This current systematic review aimed to evaluate the current evidence on the effect of topical capsaicin application to alleviate symptoms related to burning mouth syndrome (BMS). PubMed, Ovid SP, and Cochrane were searched from 1980 to 2022 to identify relevant literature. A total of 942 titles (PubMed, 84; Ovid SP, 839; Cochrane, 19) was retrieved, of which 936 were excluded based on the title and abstract. A total of 11 studies were further evaluated for full text analysis, of which 7 were excluded. As a result, 4 articles were included for qualitative synthesis of data. Capsaicin as a mouthwash can have potential application in the treatment of symptoms related to burning mouth. The quality of available studies is moderate to low, and a well-designed randomized multicentric study comparing capsaicin with other active agents is planned to obtain more definitive conclusions.

High frequencies of vitamin B12 and folic acid deficiencies and hyperhomocysteinemia in Taiwanese male patients with oral submucous fibrosis

Background

/purpose: Oral submucous fibrosis (OSF) is a betel quid chewing-caused oral mucosal disease with progressive collagen deposition. This study evaluated whether Taiwanese male OSF patients had high frequencies of vitamin B12 and folic acid deficiencies, hyperhomocysteinemia, and serum gastric parietal cell antibody (GPCA) positivity.

Materials and methods

The blood hemoglobin (Hb), serum iron, vitamin B12, folic acid, homocysteine, and GPCA concentrations in 62 male OSF patients were measured and compared with the corresponding data in 124 age-matched male healthy control subjects.

Results

We found that 5 (8.1%), 12 (19.4%), 32 (51.6%), 31 (50.0%), 22 (35.5%), and 6 (9.7%) of the 62 male OSF patients had Hb (<13 g/dL), iron (≤70 μg/dL), vitamin B12 (≤450 pg/mL), and folic acid (≤6 ng/mL) deficiencies, hyperhomocysteinemia (>12 μM), and serum GPCA positivity, respectively. Furthermore, OSF patients had significantly higher frequencies of Hb (P = 0.006), vitamin B12 (P < 0.001), and folic acid (P < 0.001) deficiencies, hyperhomocysteinemia (P < 0.001), and serum GPCA positivity (P = 0.030) than 124 healthy control subjects. Of the 22 OSF patients with hyperhomocysteinemia, 4 had vitamin B12 deficiency only, 7 had folic acid deficiency only, and 11 had both vitamin B12 and folic acid deficiencies.

Conclusion

We conclude that Taiwanese male OSF patients have high frequencies of vitamin B12 and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity. The hyperhomocysteinemia in our OSF patients is predominantly due to deficiencies of either vitamin B12 or folic acid or both.

Higher frequencies of anemia, vitamin B12 deficiency, and gastric parietal cell antibody positivity in folic acid-deficient Taiwanese male oral submucous fibrosis patients

Background/purpose

Oral submucous fibrosis (OSF) is a progressive fibrotic oral mucosal disease associated with betel quid chewing. This study evaluated whether Taiwanese male OSF patients with folic acid (FA) deficiency (the serum FA level ≤6 ng/mL, so-called FA-deficient OSF patients) had high frequencies of blood hemoglobin (Hb) and serum iron and vitamin B12 deficiencies, and serum gastric parietal cell antibody (GPCA) positivity.

Materials and methods

The blood Hb and serum iron, vitamin B12, FA, and GPCA concentrations in 59 Taiwanese male FA-deficient OSF patients were measured and compared with the corresponding data in 118 age-matched healthy male control subjects.

Results

We found that 3 (5.1%), 35 (59.3%), and 7 (11.9%) of the 59 FA-deficient OSF patients had blood Hb (<13 g/dL) and serum vitamin B12 (≤450 pg/mL) deficiencies, and serum GPCA positivity, respectively. Furthermore, 59 FA-deficient OSF patients had significantly higher frequencies of serum vitamin B12 deficiency and serum GPCA positivity than 118 healthy control subjects (all P-values <0.05). Of the 3 anemic FA-deficient OSF patients, one had macrocytic anemia and the other two had thalassemia trait-induced anemia.

Conclusion

We conclude that Taiwanese male FA-deficient OSF patients have high frequencies of serum vitamin B12 deficiency and GPCA positivity than healthy control subjects. The vitamin B12 and FA deficiencies in FA-deficient OSF patients are more likely due to OSF symptoms and signs-caused insufficient intake, difficulty in chewing and swallowing, and malabsorption of food fragment-bound vitamin B12 and FA rather than the GPCA positivity in these OSF patients.

Higher frequencies of anemia, hematinic deficiencies, and gastric parietal cell antibody positivity in vitamin B12-deficient Taiwanese male oral submucous fibrosis patients

Abstract Background/purpose

Oral submucous fibrosis (OSF) is a progressive fibrotic oral mucosal disease associated with betel quid chewing. This study evaluated whether Taiwanese male OSF patients with vitamin B12 deficiency (the serum vitamin B12 level ≤ 450 pg/mL, B12-deficient OSF patients) had high frequencies of blood hemoglobin (Hb) and serum iron and folic acid deficiencies, and serum gastric parietal cell antibody (GPCA) positivity.

Materials and methods

The blood Hb and serum iron, vitamin B12, folic acid, and GPCA concentrations in 66 Taiwanese male B12-deficient OSF patients were measured and compared with the corresponding data in 132 age-matched healthy male control subjects.

Results

We found that 6 (9.1%), 19 (28.8%), 35 (53.0%), and 9 (13.6%) of the 66 B12-deficient OSF patients had blood Hb (<13 g/dL) and serum iron (≤70 μg/dL), and folic acid (≤6 ng/mL) deficiencies, and serum GPCA positivity, respectively. Furthermore, 66 OSF patients had significantly higher frequencies of blood Hb and serum iron and folic acid deficiencies, and serum GPCA positivity than 132 healthy control subjects (all P-values < 0.05). Of the 6 anemic B12-deficient OSF patients, one had macrocytic anemia, two normocytic anemia, and three thalassemia trait-induced anemia.

Conclusion

Taiwanese male B12-deficient OSF patients have high frequencies of blood Hb, serum iron and folic acid deficiencies, and serum GPCA positivity. The anemia and hematinic deficiencies in B12-deficient OSF patients are likely due to OSF symptoms and signs-caused insufficient intake, poor chewing, and malabsorption of hematinic elements from ingested food stuffs rather than the GPCA positivity.
