Abstract

Background/Purpose: Our previous study found that 9 of 63 recurrent aphthous stomatitis (RAS)/Behcet's disease (BD) patients have serum gastric parietal cell antibody (GPCA) positivity. This study assessed whether serum GPCA positivity or RAS/BD itself was a significant factor causing hematinic deficiencies and hyperhomocysteinemia in GPCA-positive RAS/BD (GPCA + RAS/BD) or gastric and thyroid autoantibodies-negative RAS/BD (Abs RAS/BD) patients. Methods: The mean blood hemoglobin (Hb), iron, vitamin B12, folic acid, and homocysteine levels were measured and compared between any two of three groups of 9 GPCA + RAS/BD patients, 41 Abs RAS/BD patients, and 126 healthy control subjects. Results: GPCA + RAS/BD patients had significantly lower mean blood Hb (for men only), iron (for men only), and vitamin B12 levels as well as a significantly higher mean serum homocysteine level than 126 healthy control subjects. Moreover, GPCA + RAS/BD patients had significantly greater frequencies of blood Hb, iron, and vitamin B12 deficiencies and of hyperhomocysteinemia than healthy control subjects. GPCA + RAS/BD patients did have a significantly lower mean serum vitamin B12 level and a significantly higher mean serum homocysteine level as well as significantly greater frequencies of vitamin B12 deficiency and of hyperhomocysteinemia than Abs RAS/BD patients. Moreover, Abs RAS/BD patients did have significantly lower mean blood Hb, iron, and folic acid levels and significantly greater frequencies of blood Hb and iron deficiencies than healthy control subjects. Conclusion: The GPCA is a major factor causing vitamin B12 deficiency and hyperhomocyteinemia in GPCA + RAS/BD patients. RAS/BD itself does play a significant role in causing anemia and hematinic deficiencies in both GPCA + RAS/BD and Abs RAS/BD patients.
