  • severe Megaloblastic Anemia vitamin deficiency and other causes
    Cleveland Clinic Journal of Medicine, 2020
    Co-Authors: Daniel S Socha, Sherwin I Desouza, Aron Flagg, Mikkael A Sekeres, Heesun J Rogers
    Abstract:

    Megaloblastic Anemia causes macrocytic Anemia from ineffective red blood cell production and intramedullary hemolysis. The most common causes are folate (vitamin B9) deficiency and cobalamin (vitamin B12) deficiency. Megaloblastic Anemia can be diagnosed based on characteristic morphologic and laboratory findings. However, other benign and neoplastic diseases need to be considered, particularly in severe cases. Therapy involves treating the underlying cause—eg, with vitamin supplementation in cases of deficiency, or with discontinuation of a suspected medication.

  • drug induced Megaloblastic Anemia
    The New England Journal of Medicine, 2015
    Co-Authors: Charles Hesdorffer, Dan L Longo
    Abstract:

    Many common drugs induce Megaloblastic Anemia by interfering with folate or vitamin B12 absorption, altering B12 metabolism, or blocking pathways in which these vitamins play a role. Supplements to overcome these effects or discontinuation of the drug may be necessary.

  • laboratory testing for cobalamin deficiency in Megaloblastic Anemia
    American Journal of Hematology, 2013
    Co-Authors: Matthew J Oberley, David T Yang
    Abstract:

    Cobalamin (vitamin B12) deficiency is a common cause of Megaloblastic Anemia in Western populations. Laboratory evaluation of Megaloblastic Anemia frequently includes the assessment of patient cobalamin and folate status. Current total serum cobalamin measurements are performed in the clinical laboratory with competitive binding luminescence assays, whose results may not always accurately reflect actual cobalamin stores. Surrogate markers of cobalamin deficiency such as methylmalonic acid and homocysteine have been utilized to improve diagnostic accuracy; however, the specificity of these tests by themselves is rather low. Measurement of the biologically active fraction of cobalamin, holotranscobalamin, has been proposed as a replacement for current total cobalamin assays. Although holotranscobalamin measurements appear to have slighter better sensitivity, the specificity of this assay remains to be determined. The relative merits and demerits of commonly available methods to assess cobalamin deficiency in patients with suspected Megaloblastic Anemia are discussed. Am. J.
