Abstract
Background/purpose Macrocytosis is defined as having the mean corpuscular volume (MCV) ≥ 100 fL. This study evaluated whether 46 burning mouth syndrome (BMS) patients with macrocytosis had significantly higher frequencies of anemia, hematinic deficiencies, hyperhomocysteinemia, and serum gastric parietal cell antibody (GPCA) positivity than 442 healthy control subjects or 884 BMS patients. Materials and methods Complete blood count, serum iron, vitamin B12, folic acid, homocysteine, and GPCA levels in 46 BMS patients with macrocytosis, 884 BMS patients, and 442 healthy control subjects were measured and compared. Results We found that 65.2%, 23.9%, 47.8%, 0.0%, 60.9%, and 45.7% of 46 BMS patients with macrocytosis were diagnosed as having blood hemoglobin, iron, vitamin B12, and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity, respectively. Moreover, 46 BMS patients with macrocytosis had significantly higher frequencies of blood hemoglobin and serum vitamin B12 deficiencies, hyperhomocysteinemia, and serum GPCA positivity than 442 healthy control subjects or 884 BMS patients (all P-values < 0.001). In addition, 46 BMS patients with macrocytosis also had a significantly higher frequency of serum iron deficiency than 442 healthy control subjects (P < 0.001). Pernicious anemia was found in 15 BMS patients with macrocytosis. Conclusion There are significantly higher frequencies of anemia and serum iron and vitamin B12 deficiencies, hyperhomocysteinemia, and serum GPCA positivity in BMS patients with macrocytosis than in healthy control subjects. BMS patients with macrocytosis also have significantly higher frequencies of anemia, serum vitamin B12 deficiency, hyperhomocysteinemia, and serum GPCA positivity than BMS patients.

Lee YP, Loh CH, Hwang MJ, Lin CP. Vitamin B12 deficiency and anemia in 140 Taiwanese female lacto-vegetarians. J Formos Med Assoc 2021; 120:2003-2009. [PMID: 33906782 DOI: 10.1016/j.jfma.2021.04.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 04/04/2021] [Accepted: 04/08/2021] [Indexed: 10/21/2022] Open
Abstract
BACKGROUND/PURPOSE Lacto-vegetarians (LVs) tend to have vitamin B12 deficiency (B12D). This study assessed whether 140 female LVs, including 16 B12D/LVs and 124 non-B12D/LVs, had significantly higher frequencies of microcytosis, macrocytosis, and of blood hemoglobin (Hb), red blood cell (RBC), and serum vitamin B12 deficiencies than 140 healthy control subjects (HCSs). METHODS The complete blood count and serum vitamin B12 level in 140 female LVs and 140 female HCSs were measured and compared. RESULTS We found that 8.6%, 4.3%, 22.9%, 20.0%, and 11.4% of 140 LVs had microcytosis, macrocytosis, and blood Hb, RBC, and serum vitamin B12 deficiencies, respectively. The 140 LVs, 16 B12D/LVs, and 124 non-B12D/LVs had significantly higher frequencies of microcytosis as well as blood Hb and RBC deficiencies than 140 HCSs (all P-values < 0.005). Moreover, both 140 LVs and 124 non-B12D/LVs had significantly higher frequencies of macrocytosis than 140 HCSs. In this study, 32 (22.9%) of 140 LVs including 5 B12D/LVs and 27 non-B12D/LVs had anemia. Of the 5 anemic B12D/LVs, three had normocytic anemia, one had iron deficiency anemia (IDA), and one had thalassemia trait-induced anemia. Moreover, of the 27 anemic non-B12D/LVs, 18 had normocytic anemia, one had IDA, one had thalassemia trait-induced anemia, and 7 had microcytic anemia other than IDA and thalassemia trait-induced anemia. CONCLUSION LVs have significantly higher frequencies of microcytosis, macrocytosis, blood Hb, RBC, and serum vitamin B12 deficiencies than HCSs. Normocytic and microcytic anemias are the two most common types of anemia in our LVs.
