    Co-Authors: Ying Tai Jin, Chunpin Chiang, Julia Yu Fong Chang, Andy Sun
    Abstract:

    Abstract Background/purpose Our previous study found 109 gastric Parietal Cell Antibody (GPCA)-positive burning mouth syndrome (BMS) patients (so-called GPCA+BMS patients in this study) in a group of 884 BMS patients. This study evaluated whether high-titer (GPCA titer ≥ 160) GPCA+BMS patients had greater frequencies of macrocytosis, anemia, serum iron and vitamin B12 deficiencies, and hyperhomocysteinemia than low-titer (GPCA titer Materials and methods Complete blood count, serum iron, vitamin B12, folic acid, homocysteine, and GPCA levels in 42 high-titer GPCA+BMS patients, 67 low-titer GPCA+BMS patients, and 442 healthy control subjects were measured and compared. Results We found that 33.3%, 38.1%, 19.0%, 33.3%, 2.4%, and 57.1% of 42 high-titer GPCA+BMS patients and 10.4%, 25.4%, 14.9%, 6.0%, 1.5%, and 11.9% of 67 low-titer GPCA+BMS patients were diagnosed as having macrocytosis, blood hemoglobin, iron, vitamin B12, and folic acid deficiencies, and hyperhomocysteinemia, respectively. Moreover, both 42 high-titer and 67 low-titer GPCA+BMS patients had significantly greater frequencies of macrocytosis, blood hemoglobin, serum iron and vitamin B12 deficiencies, and hyperhomocysteinemia than 442 healthy control subjects (all P-values Conclusion The high-titer GPCA+BMS patients have significantly greater frequencies of macrocytosis, anemia, serum iron and vitamin B12 deficiencies, and hyperhomocysteinemia than healthy control subjects and significantly greater frequencies of macrocytosis, serum vitamin B12 deficiency, and hyperhomocysteinemia than low-titer GPCA+BMS patients.

  • anemia hematinic deficiencies and hyperhomocysteinemia in burning mouth syndrome patients with thyroglobulin Antibody thyroid microsomal Antibody positivity but without gastric Parietal Cell Antibody positivity
    Journal of Dental Sciences, 2021
    Co-Authors: Ying Tai Jin, Chunpin Chiang, Julia Yu Fong Chang, Andy Sun
    Abstract:

    Abstract Background/purpose Our previous study found that 222 of 884 burning mouth syndrome (BMS) patients have thyroglobulin Antibody (TGA) positivity and/or thyroid microsomal Antibody (TMA) positivity but without gastric Parietal Cell Antibody positivity (GPCAˉTGA+/TMA+BMS patients). This study mainly assessed whether the serum TGA/TMA positivity was significantly associated with anemia, hematinic deficiencies, and hyperhomocysteinemia in GPCAˉTGA+/TMA+BMS patients. Materials and methods The complete blood count, iron, vitamin B12, folic acid, and homocysteine levels were measured and compared between 222 GPCAˉTGA+/TMA+BMS patients and 553 GPCA-negative, TGA-negative, and TMA-negative BMS patients (GPCAˉTGAˉTMAˉBMS patients) or 442 healthy control subjects. Results We found that 222 GPCAˉTGA+/TMA+BMS patients had significantly lower mean corpuscular volume (MCV) and lower blood Hb and serum iron levels than 442 healthy control subjects and significantly lower MCV and lower serum homocysteine levels than 553 GPCAˉTGAˉTMAˉBMS patients. Moreover, 222 GPCAˉTGA+/TMA+BMS patients had significantly greater frequencies of microcytosis, macrocytosis, blood Hb and serum iron deficiencies, and hyperhomocysteinemia than 442 healthy control subjects and significantly higher frequency of microcytosis but significantly lower frequency of hyperhomocysteinemia than 553 GPCAˉTGAˉTMAˉBMS patients. However, no significant differences in the frequencies of macrocytosis, blood Hb, serum iron, vitamin B12, and folic acid deficiencies were discovered between 222 GPCAˉTGA+/TMA+BMS patients and 553 GPCAˉTGAˉTMAˉBMS patients. Conclusion We conclude that the disease of BMS itself does play a significant role in causing macrocytosis, anemia, hematinic deficiencies, and hyperhomocysteinemia in GPCAˉTGA+/TMA+BMS patients. However, the serum TGA/TMA-positivity is not significantly associated with anemia and serum iron, vitamin B12, and folic acid deficiencies in GPCAˉTGA+/TMA+BMS patients.

    Journal of the Formosan Medical Association, 2020
    Co-Authors: Chunpin Chiang, Julia Yu Fong Chang, Yiping Wang, Andy Sun
    Abstract:

    Background/Purpose Gastric Parietal Cell Antibody (GPCA), thyroglobulin Antibody (TGA), and thyroid microsomal Antibody (TMA) are organ-specific autoantibodies. This study mainly assessed the frequencies of serum GPCA, TGA, and TMA positivities in burning mouth syndrome (BMS) patients. Methods Serum GPCA, TGA, and TMA levels were measured in 884 BMS patients and in 442 age- and sex-matched healthy control subjects. Results We found that 12.3%, 21.6%, and 22.7% of 884 BMS patients and 1.8%, 2.3%, and 2.9% of 442 healthy control subjects had the serum GPCA, TGA, and TMA positivities, respectively. BMS patients had significantly higher frequencies of GPCA, TGA, and TMA positivities than healthy control subjects (all P-values  Conclusion Approximately 37.5% of 884 BMS patients have serum GPCA/TGA/TMA positivity. Moreover, 12.3%, 21.6%, and 22.7% of 884 BMS patients have the serum GPCA, TGA, and TMA positivities, respectively. Only 5.1% and 7.1% of TGA/TMA-positive BMS patients have hyperthyroidism and hypothyroidism, respectively. It needs further studies to know whether GPCA-positive BMS patients may finally become as having autoimmune atrophic gastritis.

  • atrophic glossitis etiology serum autoantibodies anemia hematinic deficiencies hyperhomocysteinemia and management
    Journal of the Formosan Medical Association, 2020
    Co-Authors: Chunpin Chiang, Yuhsueh Wu, Julia Yu Fong Chang, Yiping Wang, Yang Che Wu
    Abstract:

    Atrophic glossitis (AG) is characterized by the partial or complete absence of filiform papillae on the dorsal surface of the tongue. AG may reflect the significant deficiencies of some major nutrients including riboflavin, niacin, pyridoxine, vitamin B12, folic acid, iron, zinc, and vitamin E. Moreover, protein-calorie malnutrition, candidiasis, Helicobacter pylori colonization, xerostomia, and diabetes mellitus are also the etiologies of AG. Our previous study found the serum gastric Parietal Cell Antibody (GPCA), thyroglobulin Antibody (TGA), and thyroid microsomal Antibody (TMA) positivities in 26.7%, 28.4%, and 29.8% of 1064 AG patients, respectively. We also found anemia, serum iron, vitamin B12, and folic acid deficiencies, and hyperhomocysteinemia in 19.0%, 16.9%, 5.3%, 2.3%, and 11.9% of 1064 AG patients, respectively. Moreover, GPCA-positive AG patients tended to have relatively higher frequencies of hemoglobin, iron, and vitamin B12 deficiencies and hyperhomocysteinemia than GPCA-negative AG patients. Supplementations with vitamin BC capsules plus corresponding deficient hematinics for those AG patients with hematinic deficiencies can achieve complete remission of oral symptoms and AG in some AG patients. Therefore, it is very important to examine the complete blood count, serum hematinic, homocysteine, and autoAntibody levels in AG patients before we start to offer treatments for AG patients.

Results We found that 222 GPCAˉTGA+/TMA+BMS patients had significantly lower mean corpuscular volume (MCV) and lower blood Hb and serum iron levels than 442 healthy control subjects and significantly lower MCV and lower serum homocysteine levels than 553 GPCAˉTGAˉTMAˉBMS patients. Moreover, 222 GPCAˉTGA+/TMA+BMS patients had significantly greater frequencies of microcytosis, macrocytosis, blood Hb and serum iron deficiencies, and hyperhomocysteinemia than 442 healthy control subjects and significantly higher frequency of microcytosis but significantly lower frequency of hyperhomocysteinemia than 553 GPCAˉTGAˉTMAˉBMS patients. However, no significant differences in the frequencies of macrocytosis, blood Hb, serum iron, vitamin B12, and folic acid deficiencies were discovered between 222 GPCAˉTGA+/TMA+BMS patients and 553 GPCAˉTGAˉTMAˉBMS patients. Conclusion We conclude that the disease of BMS itself does play a significant role in causing macrocytosis, anemia, hematinic deficiencies, and hyperhomocysteinemia in GPCAˉTGA+/TMA+BMS patients. However, the serum TGA/TMA-positivity is not significantly associated with anemia and serum iron, vitamin B12, and folic acid deficiencies in GPCAˉTGA+/TMA+BMS patients.

    Abstract:

    Background/purpose Our previous study found that 70 of 884 burning mouth syndrome (BMS) patients have serum gastric Parietal Cell Antibody (GPCA) positivity but without thyroglobulin Antibody (TGA) and thyroid microsomal Antibody (TMA) (so-called GPCA+TGA-TMA-BMS patients). This study assessed whether these 70 GPCA+TGA-TMA-BMS patients had significantly higher frequencies of macrocytosis, anemia, hematinic deficiencies, and hyperhomocysteinemia than 553 GPCA-negative, TGA-negative, and TMA-negative BMS (GPCA-TGA-TMA-BMS) patients or 442 healthy control subjects. Materials and methods Complete blood count, serum iron, vitamin B12, folic acid, homocysteine, GPCA, TGA, and TMA levels in 70 GPCA+TGA-TMA-BMS patients, 553 GPCA-TGA-TMA-BMS patients, and 442 healthy control subjects were measured and compared. Results We found that 15.7%, 28.6%, 20.0%, 11.4%, 2.9%, and 25.7% of 70 GPCA+TGA-TMA-BMS patients and 3.8%, 17.7%, 15.9%, 3.8%, 2.7%, and 20.1% of 553 GPCA-TGA-TMA-BMS patients had macrocytosis, blood hemoglobin, iron, vitamin B12, and folic acid deficiencies, and hyperhomocysteinemia, respectively. Moreover, both 70 GPCA+TGA-TMA-BMS patients and 553 GPCA-TGA-TMA-BMS patients had significantly greater frequencies of macrocytosis, blood hemoglobin, serum iron, vitamin B12, and folic acid deficiencies, and hyperhomocysteinemia than 442 healthy control subjects (all P-values < 0.05). In addition, 70 GPCA+TGA-TMA-BMS patients also had greater frequencies of macrocytosis, anemia, serum vitamin B12 deficiency, and hyperhomocysteinemia than 553 GPCA-TGA-TMA-BMS patients (all P-values < 0.05). Conclusion The GPCA + TGA-TMA-BMS patients have significantly greater frequencies of macrocytosis, anemia, serum iron, vitamin B12, and folic acid deficiencies, and hyperhomocysteinemia than healthy control subjects and significantly greater frequencies of macrocytosis, anemia, serum vitamin B12 deficiency, and hyperhomocysteinemia than GPCA-TGA-TMA-BMS patients.

    Co-Authors: Chunpin Chiang, Julia Yu Fong Chang, Yiping Wang, Andy Sun
    Abstract:

    Background/Purpose Gastric Parietal Cell Antibody (GPCA), thyroglobulin Antibody (TGA), and thyroid microsomal Antibody (TMA) are organ-specific autoantibodies. This study mainly assessed the frequencies of serum GPCA, TGA, and TMA positivities in burning mouth syndrome (BMS) patients. Methods Serum GPCA, TGA, and TMA levels were measured in 884 BMS patients and in 442 age- and sex-matched healthy control subjects. Results We found that 12.3%, 21.6%, and 22.7% of 884 BMS patients and 1.8%, 2.3%, and 2.9% of 442 healthy control subjects had the serum GPCA, TGA, and TMA positivities, respectively. BMS patients had significantly higher frequencies of GPCA, TGA, and TMA positivities than healthy control subjects (all P-values  Conclusion Approximately 37.5% of 884 BMS patients have serum GPCA/TGA/TMA positivity. Moreover, 12.3%, 21.6%, and 22.7% of 884 BMS patients have the serum GPCA, TGA, and TMA positivities, respectively. Only 5.1% and 7.1% of TGA/TMA-positive BMS patients have hyperthyroidism and hypothyroidism, respectively. It needs further studies to know whether GPCA-positive BMS patients may finally become as having autoimmune atrophic gastritis.

    Abstract:

    Background/Purpose Gastric Parietal Cell Antibody (GPCA), thyroglobulin Antibody (TGA), and thyroid microsomal Antibody (TMA) may be present in oral mucosal disease patients. This study mainly assessed the frequencies of serum GPCA, TGA, and TMA positivities in 131 oral precancer patients. Methods Serum GPCA, TGA, and TMA levels were measured in 131 oral precancer patients including 96 oral leukoplakia, 26 oral erythroleukoplakia, and 9 oral verrucous hyperplasia patients and in 131 age- and sex-matched healthy control subjects. Results We found that 131 oral precancer patients had higher frequencies of serum GPCA (10.7% vs. 2.3%, P = 0.012, statistically significant), TGA (4.6% vs. 2.3%, P = 0.498), and TMA (8.4% vs. 2.3%, P = 0.054, marginal significance) positivities than 131 healthy control subjects. We also found that 1 (0.8%), 6 (4.6%), and 16 (12.2%) oral precancer patients had the presence of three (GPCA + TGA + TMA), two (GPCA + TGA, GPCA + TMA, or TGA + TMA), or one (GPCA only, TGA only, or TMA only) autoAntibody in their sera, respectively. Of 10 TGA/TMA-positive oral precancer patients whose serum thyroid-stimulating hormone (TSH) levels were measured, 80%, 10%, and 10% of these 10 TGA/TMA-positive oral precancer patients had normal, lower, and higher serum TSH levels, respectively. We also found a significantly higher GPCA positive rate in 26 smokers consuming >20 cigarettes per day than in 61 smokers consuming ≤20 cigarettes per day (P = 0.008). Conclusion Approximately 17.6% of 131 oral precancer patients have serum GPCA/TGA/TMA positivity. Only approximately 20% of TGA/TMA-positive oral precancer patients have either hypothyroidism or hyperthyroidism.

    Abstract:

    Background/Purpose Gastric Parietal Cell Antibody (GPCA), thyroglobulin Antibody (TGA), and thyroid microsomal Antibody (TMA) were rarely examined in Behcet's disease (BD) patients. This study mainly assessed the frequencies of serum GPCA, TGA, and TMA positivities in 63 BD patients. Methods The frequencies of serum GPCA, TGA, and TMA positivities in 63 BD patients, 19 major-typed recurrent aphthous stomatitis (RAS)/BD (major RAS/BD) patients, 44 minor-typed RAS/BD (minor RAS/BD) patients, 520 RAS patients, and 126 healthy control subjects were calculated and compared. Results We found that 14.3%, 20.6%, and 20.6% of 63 BD patients, 21.1%, 21.1%, and 26.3% of 19 major RAS/BD patients, 11.4%, 20.5%, and 18.2% of 44 minor RAS/BD patients, 11.5%, 18.5%, and 18.3% of 520 RAS patients, and 1.6%, 2.4%, and 2.4% of 126 healthy control subjects had serum GPCA, TGA, and TMA positivities, respectively. BD, major RAS/BD, minor RAS/BD, and RAS patients all had significantly higher frequencies of serum GPCA, TGA, and TMA positivities than healthy control subjects (all P-values  Conclusion Approximately 35% BD patients have serum GPCA/TGA/TMA positivity. However, BD patients do not have significantly higher frequencies of serum GPCA, TGA, and TMA positivities than RAS patients.

  • gastric Parietal Cell and thyroid autoantibodies in behcet s disease patients with or without atrophic glossitis
    Journal of the Formosan Medical Association, 2018
    Co-Authors: Julia Yu Fong Chang, Hsinming Chen, Yiping Wang, Andy Sun
    Abstract:

    Background/Purpose Behcet's disease (BD) patients should have recurrent aphthous stomatitis (RAS) but they may or may not have atrophic glossitis (AG). This study mainly assessed the frequencies of serum gastric Parietal Cell Antibody (GPCA), thyroglobulin Antibody (TGA), and thyroid microsomal Antibody (TMA) positivities in 30 AG-positive RAS/BD (AG+RAS/BD) and 33 AG-negative RAS/BD (AG־RAS/BD) patients. Methods The frequencies of serum GPCA, TGA, and TMA positivities in 30 AG+RAS/BD patients, 33 AG־RAS/BD patients, and 126 healthy control subjects were calculated and compared. Results We found that 20.0%, 30.0%, and 26.7% of 30 AG+RAS/BD patients, 9.1%, 12.1%, and 15.2% of 33 AG־RAS/BD patients, and 1.6%, 2.4%, and 2.4% of 126 healthy control subject had the presence of GPCA, TGA, and TMA in their sera, respectively. The 30 AG+RAS/BD patients had significantly higher frequencies of serum GPCA, TGA, and TMA positivities than healthy control subjects (all P-values  Conclusion AG+RAS/BD patients do have significantly higher frequencies of serum GPCA, TGA, and TMA positivities than healthy control subjects. This finding indicates that the concomitant presence of AG may result in significantly elevated frequencies of serum GPCA, TGA, and TMA positivities in BD patients.

  • hematinic deficiencies and anemia in gastric Parietal Cell Antibody positive and negative oral submucous fibrosis patients
    Journal of Dental Sciences, 2018
    Co-Authors: Chunpin Chiang, Julia Yu Fong Chang, Yiping Wang, Andy Sun, Hsinming Chen
    Abstract:

    Background/purpose Previous studies showed that approximately 13-15% of male oral submucous fibrosis (OSF) patients are serum gastric Parietal Cell Antibody (GPCA)-positive. This study assessed whether serum GPCA or OSF itself was a significant factor that caused hematinic deficiencies and anemia statuses in GPCA-positive or GPCA-negative OSF patients (GPCA+/OSF and GPCA-/OSF patients). Materials and methods The frequencies of macrocytosis (mean corpuscular volume or MCV ≧ 100 fL) and blood hemoglobin (Hb), iron, vitamin B12 and folic acid deficiencies were determined and compared between any two of the four groups of 149 male OSF, 23 male GPCA+/OSF, and 126 male GPCA-/OSF patients and 149 age-matched male healthy control subjects. Results All three groups of OSF patients (including 149 OSF, 23 GPCA+/OSF, and 126 GPCA-/OSF patients) had a significantly higher frequency of Hb, vitamin B12, or folic acid deficiency and of macrocytosis than 149 healthy control subjects (all P-values < 0.05). The 23 GPCA+/OSF patients did have a significantly lower mean serum vitamin B12 level and a significantly higher MCV or frequency of vitamin B12 deficiency than the 126 GPCA-/OSF patients. Two of the 23 GPCA+/OSF patients had pernicious anemia. Of the 126 GPCA-/OSF patients, 6 had macrocytic anemia, 2 had iron deficiency anemia, and 4 had thalassemia trait-induced anemia. Conclusion We conclude that OSF itself does play a significant role in causing hematinic deficiencies and anemia in OSF, GPCA+/OSF, and GPCA-/OSF patients. The serum GPCA is the major factor that causes vitamin B12 deficiency, macrocytosis, and pernicious anemia in GPCA+/OSF patients.
