Thiamine-responsive megaloblastic anemia (TRMA) is a clinical triad characterized by megaloblastic anemia, non-autoimmune diabetes mellitus, and sensory-neural hearing loss. Mutations in the thiamine transporter gene, solute carrier family 19, member 2 (SLC19A2), have been associated with TRMA. Three pediatric patients from a large consanguineous Iranian family with hyperglycemia, anemia, and h...

We report two cases of primary cold agglutinin disease (CAD) associated with megaloblastic anemia in Japanese elderly patients. Case 1 was a 67-year-old male and Case 2 was a 55-year-old male. Both patients were diagnosed with primary CAD, with continuously high cold agglutinin titers (1 : >8,192 and 1 : 16,834, resp.), monoclonal IgM-kappa light chains, and no underlying disease. In addition, ...

Anemia is one of the most common health problems in the primary care setting. Macrocytosis in adults is defined as a red blood cell (RBC) mean corpuscular volume (MCV) >100 femtoliter (fL). Macrocytic anemias are generally classified into megaloblastic or nonmegaloblastic anemia. Megaloblastic anemia is caused by deficiency or impaired utilization of vitamin B12 and/or folate, whereas nonmegalo...

Deficiency of vitamin B12 and/or folic acid as a cause of pyrexia, though known, is rarely reported in literature. We aimed to report a case in a 51 year old woman, who presented with fever and pancytopenia and was diagnosed to have megaloblastic anemia secondary to vitamin B12 and folate deficiency. The pyrexia subsided following the intramuscular injection of vitamin B12 and oral folic acid a...

Deficiency of folate or vitamin B12 (cobalamin) causes megaloblastic anemia, a disease characterized by pancytopenia due to the excessive apoptosis of hematopoietic progenitor cells. Clinical and experimental studies of megaloblastic anemia have demonstrated an impairment of DNA synthesis and repair in hematopoietic cells that is manifested by an increased percentage of cells in the DNA synthes...

By ULFAR JONSSON, 0. STUART ROATH AND CHARLOTFE I. F. KIRKPATRICK BONE MARROW CHANGES suggestive or diagnostic of megaloblastic erythropoiesis have been recognized on a number of occasions in patients with hemolytic anemia. 4 ln many of these patients evalumation of a possible response to agents effective in megaloblastic anemias has not been possible because of concurrent transfusions or for o...

Kur’sitm t m JoHN Li Er AUM S INCE THE INITIAL case reports in 1949,1,2 the occurrence of megaloblastic anemia as a complication of alcoholic cirrhosis has been reported with increasing frequency in recent years.314 Jarrold and Vilter reviewed the marrows of 30 patients with cirrhosis and found 3 to be megaloblastic.1 Krasnow et al. found the incidence of megaloblastic anemia i...

LTHOUGH megaboblastic anemia of pregnancy is considered mainly as a folic acid deficiency anemia, since this vitamin induces remission in most cases, its mechanism of production is still obscure. Dietary deficiency has been claimed to be the principal cause. However, this anemia has been observed in well-to-do women whose diet was satisfactory. Some other factors such as gastrointestinal upset,...
