Glycosylated haemoglobin (HbA1c) in iron- and vitamin B12 deficiency. 1990

P Gram-Hansen, and J Eriksen, and T Mourits-Andersen, and L Olesen

Department of Internal Medicine B, Aalborg Hospital, Denmark.

Glycosylated haemoglobin (HbA1c) was measured in 10 patients with iron deficiency anaemia, 10 patients with vitamin B12 deficiency anaemia and 10 healthy controls. Initially there were no significant differences between the groups (P greater than 0.4), but after treatment with iron and vitamin B12 for 3 and 6 weeks, the glycosylated haemoglobin concentration decreased significantly (P less than 0.01). It was concluded that glycosylated haemoglobin is a sensitive marker of the changes in the erythrocyte population that are observed when predominantly immature erythrocytes are being produced.

UI	MeSH Term	Description	Entries
D007501	Iron	A metallic element with atomic symbol Fe, atomic number 26, and atomic weight 55.85. It is an essential constituent of HEMOGLOBINS; CYTOCHROMES; and IRON-BINDING PROTEINS. It plays a role in cellular redox reactions and in the transport of OXYGEN.	Iron-56,Iron 56
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D004909	Erythrocyte Indices	ERYTHROCYTE size and HEMOGLOBIN content or concentration, usually derived from ERYTHROCYTE COUNT; BLOOD hemoglobin concentration; and HEMATOCRIT. The indices include the mean corpuscular volume (MCV), the mean corpuscular hemoglobin (MCH), and the mean corpuscular hemoglobin concentration (MCHC).

D006442	Glycated Hemoglobin	Products of non-enzymatic reactions between GLUCOSE and HEMOGLOBIN (occurring as a minor fraction of the hemoglobin of ERYTHROCYTES.) It generally refers to glycated HEMOGLOBIN A. Hemoglobin A1c (Hb A1c) is hemoglobin A with GLYCATION on a terminal VALINE of the beta chain. Glycated hemoglobin A is used as an index of the average blood sugar level over a lifetime of erythrocytes.

D000747	Anemia, Hypochromic	Anemia characterized by a decrease in the ratio of the weight of hemoglobin to the volume of the erythrocyte, i.e., the mean corpuscular hemoglobin concentration is less than normal. The individual cells contain less hemoglobin than they could have under optimal conditions. Hypochromic anemia may be caused by iron deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections or other diseases, therapeutic drugs, lead poisoning, and other conditions.

D014805	Vitamin B 12	A cobalt-containing coordination compound produced by intestinal micro-organisms and found also in soil and water. Higher plants do not concentrate vitamin B 12 from the soil and so are a poor source of the substance as compared with animal tissues. INTRINSIC FACTOR is important for the assimilation of vitamin B 12.	Cobalamin,Cyanocobalamin,Cobalamins,Eritron,Vitamin B12,B 12, Vitamin,B12, Vitamin
