Significantly higher frequencies of macrocytosis, anemia, serum vitamin B12 and folic acid deficiencies, and hyperhomocysteinemia in male than in female atrophic glossitis patients. J Dent Sci 2022; 17:1371-1377. [PMID: 35784143 PMCID: PMC9236945 DOI: 10.1016/j.jds.2022.05.011] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 05/16/2022] [Indexed: 12/31/2022] Open
Abstract
Background/purpose Our previous study found that 19.0%, 16.9%, 5.3%, 2.3%, 11.9%, and 26.7% of 1064 atrophic glossitis (AG) patients have anemia, serum iron, vitamin B12, and folic acid deficiencies, hyperhomocysteinemia, and serum gastric parietal cell antibody (GPCA) positivity, respectively. This study evaluated the anemia, hematinic deficiencies, and hyperhomocysteinemia in 150 male and 914 female AG patients. Materials and methods The blood hemoglobin (Hb) and serum iron, vitamin B12, folic acid, homocysteine, GPCA levels in 150 male and 914 female AG patients were measured and compared with the corresponding levels in 75 male and 457 female healthy control subjects (HCSs), respectively. Results We found that 150 male AG patients had significantly lower mean blood Hb, serum iron, vitamin B12, and folic acid levels, and significantly higher mean serum homocysteine levels than 75 male HCSs. Moreover, 914 female AG patients had significantly lower mean blood Hb and serum iron levels and significantly higher mean serum homocysteine level than 457 female HCSs. In addition, 150 male AG patients had significantly higher mean blood Hb and serum homocysteine levels, significantly lower mean serum vitamin B12 and folic acid levels, and significantly higher frequencies of Hb, vitamin B12, and folic acid deficiency and hyperhomocysteinemia than 914 female AG patients. Conclusion The male AG patients do have significantly higher mean blood Hb and serum homocysteine levels, significantly lower mean serum vitamin B12 and folic acid levels, and significantly higher frequencies of Hb, vitamin B12, and folic acid deficiencies and hyperhomocysteinemia than the female AG patients.

Abstract
Background/Purpose Normocytosis is defined as having the mean corpuscular volume (MCV) between 80 fL and 99.9 fL. This study evaluated whether 770 burning mouth syndrome (BMS) patients with normocytosis (so-called normocytosis/BMS patients) 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 884 BMS patients (including 770 normocytosis/BMS patients) and 442 healthy control subjects were measured and compared. Results We found that 12.3%, 13.2%, 2.2%, 2.3%, 17.3%, and 10.5% of 770 normocytosis/BMS patients had blood hemoglobin (Hb), iron, vitamin B12, and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity, respectively. Furthermore, 770 normocytosis/BMS patients had significantly higher frequencies of blood Hb, iron, vitamin B12, and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity than 442 healthy control subjects (all P-values < 0.005). On the contrary, 770 normocytosis/BMS patients had significantly lower frequencies of blood Hb and vitamin B12 deficiencies than overall 884 BMS patients (both P-values < 0.01). Conclusion We conclude that there are significantly higher frequencies of anemia, serum iron, vitamin B12, and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity in normocytosis/BMS patients than in healthy control subjects. On the contrary, normocytosis/BMS patients do have significantly lower frequencies of blood Hb and vitamin B12 deficiencies than overall BMS patients.

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.

Abstract
BACKGROUND/PURPOSE Microcytosis is defined as having mean corpuscular volume <80 fL. This study evaluated whether 68 burning mouth syndrome (BMS) patients with microcytosis and 816 BMS patients without microcytosis had higher frequencies of anemia, hematinic deficiencies, hyperhomocysteinemia, and serum gastric parietal cell antibody (GPCA) positivity than 442 healthy control subjects. MATERIALS AND METHODS Complete blood count and serum iron, vitamin B12, folic acid, homocysteine, and GPCA levels in 68 BMS patients with microcytosis, 816 BMS patients without microcytosis, and 442 healthy control subjects were measured and compared. RESULTS We found that 73.5%, 44.1%, 4.4%, 2.9%, 13.2%, and 10.3% of 68 BMS patients with microcytosis and 15.3%, 13.8%, 4.8%, 2.2%, 19.7%, and 12.5% of 816 BMS patients without microcytosis had blood hemoglobin, iron, vitamin B12, and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity, respectively. Both 68 BMS patients with microcytosis and 816 BMS patients without microcytosis had significantly higher frequencies of blood hemoglobin, iron, vitamin B12, and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity than 442 healthy control subjects (all P-values < 0.05). Moreover, 68 BMS patients with microcytosis had significantly higher frequencies of blood hemoglobin and iron deficiencies than 816 BMS patients without microcytosis. CONCLUSION There are significantly higher frequencies of anemia, serum iron, vitamin B12, and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity in BMS patients with or without microcytosis than in healthy control subjects. BMS patients with microcytosis have significantly higher frequencies of blood hemoglobin and iron deficiencies than BMS patients without microcytosis.

Abstract
BACKGROUND/PURPOSE Our previous study found the serum gastric parietal cell antibody (GPCA) positivity in 12.3% of burning mouth syndrome (BMS) patients. This study assessed whether GPCA-positive BMS (GPCA+BMS) patients had significantly higher frequencies of macrocytosis, anemia, hematinic deficiencies, and hyperhomocysteinemia than healthy control subjects or GPCA-negative BMS (GPCA-BMS) patients. METHODS The mean corpuscular volume, blood hemoglobin (Hb), and serum iron, vitamin B12, folic acid, homocysteine, and GPCA levels were measured and compared between any two of three groups of 109 GPCA+BMS patients, 775 GPCA-BMS patients, and 442 healthy control subjects. RESULTS We found that 109 GPCA+BMS patients had significantly higher frequencies of macrocytosis, blood Hb and serum iron and vitamin B12 deficiencies, and hyperhomocysteinemia than 442 healthy control subjects (all P-values < 0.001) and significantly higher frequencies of macrocytosis, blood Hb and serum vitamin B12 deficiencies, and hyperhomocysteinemia than 775 GPCA-BMS patients (all P-values < 0.01). Moreover, 775 GPCA-BMS patients had significantly higher frequencies of macrocytosis, blood Hb and serum iron, vitamin B12, and folic acid deficiencies, and hyperhomocysteinemia than 442 healthy control subjects (all P-values < 0.005). Pernicious anemia (45.5%) and normocytic anemia (24.2%) were the two most common types of anemia in 33 anemic GPCA+BMS patients. Moreover, normocytic anemia (61.3%), thalassemia trait-induced anemia (15.5%), and iron deficiency anemia (14.1%) were the three most common types of anemia in 142 anemic GPCA-BMS patients. CONCLUSION GPCA+BMS patients have significantly higher frequencies of macrocytosis, blood Hb and serum vitamin B12 deficiencies, and hyperhomocysteinemia than healthy control subjects or GPCA-BMS patients.

Abstract
BACKGROUND/PURPOSE Our previous study found that 170 of 884 burning mouth syndrome (BMS) patients have hyperhomocysteinemia. This study assessed whether these 170 BMS patients with hyperhomocysteinemia had significantly higher frequencies of anemia, hematinic deficiencies, and serum gastric parietal cell antibody (GPCA) positivity than 714 BMS patients without hyperhomocysteinemia or 442 healthy control subjects. MATERIALS AND METHODS The blood hemoglobin (Hb) and serum iron, vitamin B12, folic acid, homocysteine, and GPCA levels in 170 BMS patients with hyperhomocysteinemia, 714 BMS patients without hyperhomocysteinemia, and 442 healthy control subjects were measured and compared. RESULTS We found that 170 BMS patients with hyperhomocysteinemia had significantly higher frequencies of macrocytosis, blood Hb and serum iron, vitamin B12, and folic acid deficiencies, and serum GPCA positivity than 442 healthy control subjects (all P-values < 0.001) or 714 BMS patients without hyperhomocysteinemia (all P-values < 0.05). Anemia was found in 77 of 170 BMS patients with hyperhomocysteinemia and in 98 of 714 BMS patients without hyperhomocysteinemia. Normocytic anemia (47 cases) and pernicious anemia (15 cases) were the two most common types of anemia in 170 BMS patients with hyperhomocysteinemia. Moreover, normocytic anemia (48 cases), iron deficiency anemia (21 cases), and thalassemia trait-induced anemia (21 cases) were the three most common types of anemia in 714 BMS patients without hyperhomocysteinemia. CONCLUSION BMS patients with hyperhomocysteinemia had significantly higher frequencies of macrocytosis, anemia, serum iron, vitamin B12, and folic acid deficiencies, and serum GPCA positivity than healthy control subjects or BMS patients without hyperhomocysteinemia.

Abstract
Background/purpose Our previous study found that 143 of 884 burning mouth syndrome (BMS) patients have iron deficiency (ID). This study assessed whether all BMS patients with ID (so-called ID/BMS patients) had iron deficiency anemia (IDA) and evaluated whether the ID/BMS patients had significantly higher frequencies of anemia, hematinic deficiencies, hyperhomocysteinemia, and serum gastric parietal cell antibody (GPCA) positivity than healthy control subjects. Materials and methods The blood hemoglobin (Hb) and serum iron, vitamin B12, folic acid, homocysteine, and GPCA levels in 143 ID/BMS patients and 442 healthy control subjects were measured and compared. Results We found that 143 ID/BMS patients had significantly lower mean blood Hb and serum iron, vitamin B12, folic acid levels as well as significantly higher mean serum homocysteine level than healthy control subjects (all P-values < 0.01). Moreover, 143 ID/BMS patients had significantly higher frequencies of blood Hb (55.9%) and serum iron (100.0%), vitamin B12 (7.7%), and folic acid (2.1%) deficiencies, hyperhomocysteinemia (27.3%), and serum GPCA positivity (12.6%) than 442 healthy control subjects (all P-values < 0.001). Furthermore, of 80 anemic ID/BMS patients, 5 (6.3%) had pernicious anemia, 5 (6.3%) had macrocytic anemia other than pernicious anemia, 42 (52.5%) had normocytic anemia, 21 (26.3%) had IDA, and 7 (8.8%) had thalassemia trait-induced anemia. Conclusion ID/BMS patients had significantly higher frequencies of blood Hb and serum iron, vitamin B12, and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity than healthy control subjects. Normocytic anemia is the most common type of anemia in ID/BMS patients.

Abstract
BACKGROUND/PURPOSE Our previous study found that 56 of 1064 atrophic glossitis (AG) patients have vitamin B12 deficiency. This study assessed whether the AG patients with vitamin B12 deficiency (B12D/AG patients) had significantly higher frequencies of anemia, hematinic deficiencies, hyperhomocysteinemia, and serum gastric parietal cell antibody (GPCA) positivity than healthy control subjects. METHODS The blood hemoglobin (Hb) and serum iron, vitamin B12, folic acid, homocysteine, and GPCA levels in 56 B12D/AG patients and 532 healthy control subjects were measured and compared. RESULTS We found that 56 B12D/AG patients had significantly lower mean blood Hb and serum iron levels as well as significantly higher mean corpuscular volume (MCV) and mean serum homocysteine level than healthy control subjects (all P-values < 0.05). Moreover, 56 B12D/AG patients had significantly higher frequencies of macrocytosis (53.6%), blood Hb (64.3%), iron (26.8%), and folic acid (3.6%) deficiencies, hyperhomocysteinemia (89.3%), and serum GPCA positivity (55.4%) than 532 healthy control subjects (all P-values < 0.005). In addition, of 36 anemic B12D/AG patients, 22 (61.1%) had pernicious anemia (PA), 6 (16.7%) had macrocytic anemia other than PA, 4 (11.1%) had normocytic anemia, 3 (8.3%) had iron deficiency anemia (IDA), and one (2.8%) had microcytic anemia other than IDA and thalassemia trait-induced anemia. CONCLUSION We conclude that B12D/AG patients have significantly higher frequencies of macrocytosis, blood Hb, iron, and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity than healthy control subjects. PA is the most common type of anemia in our B12D/AG patients.

Abstract
BACKGROUND AND OBJECTIVES We performed a prospective analysis of iron status in plateletpheresis donors, using whole blood donors as a control group, to assess the haematinic effects of regular anti-coagulated extracorporeal circulation and platelet collection. MATERIALS AND METHODS Ferritin levels were measured in samples from 31 regular male plateletpheresis donors and from 14 first time male whole blood donors, immediately before and immediately after donation, and immediately before the next donation. An additional 33 regular male plateletpheresis donors and 17 first time male whole blood donors had serum ferritin levels checked predonation. RESULTS Male plateletpheresis donors had a statistically significant fall in serum ferritin after donation (P = 0.005)*. In addition, male platelet donors had significantly lower serum ferritin levels than first time male blood donors: ferritin <20 µg/L was found in 6/64 (9%) of regular platelet donors and 1/31 (3%) of first time blood donors (P < 0.001)*. DISCUSSION Our studies support the value of serum ferritin measurement in apheresis donor management.

Osteoclasts Are Required for Hematopoietic Stem and Progenitor Cell Mobilization but Not for Stress Erythropoiesis in Plasmodium chabaudi adami Murine Malaria. Mediators Inflamm 2016; 2016:3909614.

Abstract
The anemia and inflammation concurrent with blood stage malaria trigger stress haematopoiesis and erythropoiesis. The activity of osteoclasts seems required for the mobilization of hematopoietic stem and progenitor cells (HSPC) from the bone marrow to the periphery. Knowing that BALB/c mice with acute Plasmodium chabaudi adami malaria have profound alterations in bone remodelling cells, we evaluated the extent to which osteoclasts influence their hematopoietic response to infection. For this, mice were treated with osteoclast inhibiting hormone calcitonin prior to parasite inoculation, and infection as well as hematological parameters was studied. In agreement with osteoclast-dependent HSPC mobilization, administration of calcitonin led to milder splenomegaly, reduced numbers of HSPC in the spleen, and their retention in the bone marrow. Although C-terminal telopeptide (CTX) levels, indicative of bone resorption, were lower in calcitonin-treated infected mice, they remained comparable in naive and control infected mice. Calcitonin-treated infected mice conveniently responded to anemia but generated less numbers of splenic macrophages and suffered from exacerbated infection; interestingly, calcitonin also decreased the number of macrophages generated in vitro. Globally, our results indicate that although osteoclast-dependent HSC mobilization from bone marrow to spleen is triggered in murine blood stage malaria, this activity is not essential for stress erythropoiesis.

Abstract
We recently reported that acrylamide, a known rodent and probable human carcinogen, does not increase the risk of azoxymethane (AOM)-induced rat colon precancerous lesions when administered through the diet. Here, we present toxicological data from non-AOM-injected rats. Briefly, male F344 rats were randomized into four dietary groups and received experimental diets based on AIN-93G formulation and containing acrylamide at 0 (control), 5, 10 or 50mg/kg diet (wt/wt) ad libitum for 10 weeks, after which they were killed and their blood collected for hematological and biochemical markers. Acrylamide at the higher doses (10 and 50mg/kg diet) significantly lowered (p<0.05) serum total high density lipoprotein and total testosterone and increased serum lipase in comparison to the control. Blood hematocrit values and lymphocyte counts were significantly lower (p<0.05) in the high dose acrylamide (50mg/kg diet) group compared to control, with a concomitant decrease in hemoglobin level, mean corpuscular volume and mean corpuscular hemoglobin. These results provide additional hazard characterization data and strengthen the notion that at high doses, acrylamide may involve systemic toxicity potentiating tumorigenesis in experimental animals. Further studies are required to understand the health effects of food-borne acrylamide, especially at the lower exposures typified by human diets.

Abstract
Myelodysplastic syndromes (MDS) are heterogeneous malignant bone marrow disorders diagnosed most often in elderly white persons. MDS have significant clinical consequences, including cytopenias leading to infection, bleeding, and death; and approximately one-third of cases progress to acute myeloid leukemia (AML). Only one potentially curative therapy exists-allogeneic hematopoietic stem cell transplant (HSCT)-but this therapy is not widely used due to associated morbidity and mortality in elderly patients. Recent research suggests MDS occurs more frequently than previously thought and may be responsible for a substantial proportion of unexplained anemias in elderly persons. Incidence of MDS is expected to increase with increases in life expectancy. Therefore, we offer this comprehensive narrative update of MDS to inform the medical community treating the population at risk for MDS, with a focus on MDS epidemiology and clinical management in the United States. This review includes a brief historical background of MDS, provides an overview of the population burden of disease, discusses the molecular pathology of MDS, describes the clinical features and management of MDS, and discusses future directions in MDS research. Our objective is to inform general medicine practitioners and call attention to the need for translational research in MDS.

Abstract
Nutritional anemia is the most common type of anemia, affecting millions of people in all age groups worldwide. While inadequate access to food and nutrients can lead to anemia, patients with certain health status or medical conditions are also at increased risk of developing nutritional anemia. Iron, cobalamin, and folate are the most recognized micronutrients that are vital for the generation of erythrocytes. Iron deficiency is associated with insufficient production of hemoglobin. Deficiency of cobalamin or folate leads to impaired synthesis of deoxyribonucleic acid, proteins, and cell division. Recent research has demonstrated that the status of copper and zinc in the body can significantly affect iron absorption and utilization. With an increasing number of patients undergoing bariatric surgical procedures, more cases of anemia associated with copper and zinc deficiencies have also emerged. The intestinal absorption of these 5 critical micronutrients are highly regulated and mediated by specific apical transport mechanisms in the enterocytes. Health conditions that persistently alter the histology of the upper intestinal architecture, expression, or function of these substrate-specific transporters, or the normal digestion and flow of these key micronutrients, can lead to nutritional anemia. The focus of this article is to review the science of intestinal micronutrient absorption, discuss the clinical assessment of micronutrient deficiencies in relation to anemia, and suggest an effective treatment plan and monitoring strategies using an evidence-based approach.

Abstract
Erythropoiesis, the bone marrow production of erythrocytes by the proliferation and differentiation of hematopoietic cells, replaces the daily loss of 1% of circulating erythrocytes that are senescent. This daily output increases dramatically with hemolysis or hemorrhage. When erythrocyte production rate of erythrocytes is less than the rate of loss, chronic anemia develops. Normal erythropoiesis and specific abnormalities of erythropoiesis that cause chronic anemia are considered during three periods of differentiation: a) multilineage and pre-erythropoietin-dependent hematopoietic progenitors, b) erythropoietin-dependent progenitor cells, and c) terminally differentiating erythroblasts. These erythropoietic abnormalities are discussed in terms of their pathophysiological effects on the bone marrow cells and the resultant changes that can be detected in the peripheral blood using a clinical laboratory test, the complete blood count.
