Assessing Diagnostic Accuracy of Serum Holotranscobalamin (Active-B12) in Comparison with Other Markers of Vitamin B12 Deficiency.

Indian J Clin Biochem 2020 Jul 12;35(3):367-372. Epub 2019 Jun 12.

Department of Clinical Biochemistry, Christian Medical College, Vellore, Tamil Nadu 632004 India.

About 15-40% India is Vitamin B12 deficient (commonly diagnosed by total Vitamin B12) but, as only holoTC (active form) is taken up by body cells, thus measuring holoTC is more reflective of Vitamin B12 status than the former. We aimed to assess diagnostic accuracy of serum holoTC in comparison with total Vitamin B12 and total Homocysteine (HCY) as indicator of serum Vitamin B12 status. 217 human subjects (99 males and 118 females) ranging from 17 to 83 years were divided into Vitamin B12 deficient (n = 70), borderline (n = 100) and sufficient groups (n = 47) who were further assessed for markers of Vitamin B12 deficiency-holoTC, HCY, Mean Corpuscular Volume (MCV), Folate, heamoglobin and creatinine.

Biochemical analysis of patients with mutations in MTHFD1 and a diagnosis of methylenetetrahydrofolate dehydrogenase 1 deficiency.

Mol Genet Metab 2020 Jul 5;130(3):179-182. Epub 2020 May 5.

Department of Human Genetics, McGill University, Montreal, Quebec, Canada.; Division of Medical Genetics, Department of Specialized Medicine, McGill University Health Centre, Montreal, Quebec, Canada.; Research Institute of the McGill University Health Centre, Montreal, Quebec, Canada.; Division of Medical Biochemistry, Department of Specialized Medicine, McGill University Health Centre, Montreal, Quebec, Canada.

MTHFD1 is a trifunctional protein containing 10-formyltetrahydrofolate synthetase, 5,10-methenyltetrahydrofolate cyclohydrolase and 5,10-methylenetetrahydrofolate dehydrogenase activities. It is encoded by MTHFD1 and functions in the cytoplasmic folate cycle where it is involved in de novo purine synthesis, synthesis of thymidylate and remethylation of homocysteine to methionine. Since the first reported case of severe combined immunodeficiency resulting from MTHFD1 mutations, seven additional patients ascertained through molecular analysis have been reported with variable phenotypes, including megaloblastic anemia, atypical hemolytic uremic syndrome, hyperhomocysteinemia, microangiopathy, infections and autoimmune diseases.

Discov Med 2019 Nov-Dec;28(155):247-253

Section of Thrombosis and Benign Hematology, The University of Texas M.D. Anderson Cancer Center, Houston, Texas 77030, USA.

Pernicious anemia (PA), the commonest cause of cobalamin deficiency (CD) in the world, is an autoimmune disease of multifactorial origin and is characterized by chronic atrophic gastritis (CAG) and defective absorption of cobalamin from the terminal ileum due to interference by the intrinsic factor (IF) antibodies. PA-related CD is a lengthy process, which if untreated, can lead to irreversible hematological and neurological sequelae. Although safe and effective therapy is available and the management of PA is straightforward, the diagnosis of PA can be extremely difficult to obtain due to myriad and diverse clinical presentations, frequently coexisting diseases, and limitations of currently available diagnostic tests.

Vitamin B12 deficiency mimicking acute leukemia.

Proc (Bayl Univ Med Cent) 2019 Oct 30;32(4):589-592. Epub 2019 Jul 30.

Department of Hematology and Oncology, University of Arkansas for Medical SciencesLittle RockArkansas.

Vitamin B12 deficiency can cause extensive hematologic alterations such as pancytopenia, macrocytosis, hypersegmentation of neutrophils, and hypercellular bone marrow with blastic differentiation. These dysplastic changes can sometimes be so profound that they mimic myelodysplastic syndromes or even acute leukemia, leading to extensive workup and aggressive treatment measures. We present a patient who was referred to our tertiary care medical center for treatment of suspected acute myeloid leukemia on the basis of peripheral smear and bone marrow biopsy findings, and induction chemotherapy was considered.
