Abstract

Background/purpose: Macrocytosis is defined as having the mean corpuscular volume (MCV) ≥ 100 fL. This study assessed hematinic deficiencies and pernicious anemia (PA) in oral mucosal disease patients with macrocytosis. Methods: The blood hemoglobin (Hb), iron, vitamin B12, folic acid, and homocysteine concentrations and MCV in 60 oral mucosal disease patients with macrocytosis were measured and compared with the corresponding data in 120 age- and sex-matched healthy control participants. PA was defined by the World Health Organization (WHO) as having an Hb concentration < 13 g/dL for men and < 12 g/dL for women, an MCV ≥ 100 fL, a serum vitamin B12 level < 200 pg/mL, and serum gastric parietal cell antibody (GPCA) positivity. Results: We found that 30 (50.0%), 7 (11.7%), 24 (40.0%), and three (5.0%) oral mucosal disease patients with macrocytosis had deficiencies of Hb (men < 13 g/dL, women < 12 g/dL), iron (< 60 μg/dL), vitamin B12 (< 200 pg/mL), and folic acid (< 4 mg/mL), respectively. Moreover, 38 (63.3%) and 16 (26.7%) macrocytosis patients had abnormally high blood homocysteine level (> 12.3 μM) and serum GPCA positivity, respectively. Macrocytosis patients had a significantly higher frequency of Hb, iron, or vitamin B12 deficiency, of abnormally elevated blood homocysteine level, and of GPCA positivity than healthy control participants (p < 0.001). However, only 16.7% of 60 macrocytosis patients were diagnosed as having PA by the WHO definition. Conclusion: Only 16.7% of oral mucosal disease patients with macrocytosis are discovered to have PA by the WHO definition.
