We studied the electrophoretic pattern of hemoglobin (Hb) and red blood cell indices in 128 women divided into four groups: group I, 36 nonanemic hyperthyroid women, divided in two subgroups: 36 with untreated hyperthyroidism (subgroup IA) and 9 made euthyroid by antithyroid drug therapy (subgroup IB); group II, 12 nonanemic women with untreated hypothyroidism; group III, 30 women known to be heterozygous for beta-thalassemia; and group IV, 50 healthy women. The mean (+/- SEM) HbA2 level was higher (P less than 0.001) in subgroup IA (3.21 +/- 0.06%) than in subgroup IB (2.42 +/- 0.09%) and group IV (2.48 +/- 0.04%), but lower (P less than 0.001) than in group III (5.26 +/- 0.12%). The mean HbA2 level was lower (P less than 0.001) in group II (1.99 +/- 0.08%) than in group IV. Hb fetal was detectable in eight patients of subgroup IA and undetectable in subgroup IB and groups II and IV. The mean cellular volume was lower (P less than 0.001) in subgroup IA than in other nonanemic groups. The mean cellular volume was higher (P less than 0.001) in group II than in group IV. Follow-up of nine patients who became euthyroid with treatment showed the normalization of these erythrocyte parameters. These results suggest that thyroid hormones can modulate the synthesis of delta- and gamma-globin chains.

UI MeSH Term Description Entries
D006980 Hyperthyroidism Hypersecretion of THYROID HORMONES from the THYROID GLAND. Elevated levels of thyroid hormones increase BASAL METABOLIC RATE. Hyperthyroid,Primary Hyperthyroidism,Hyperthyroidism, Primary,Hyperthyroids
D007037 Hypothyroidism A syndrome that results from abnormally low secretion of THYROID HORMONES from the THYROID GLAND, leading to a decrease in BASAL METABOLIC RATE. In its most severe form, there is accumulation of MUCOPOLYSACCHARIDES in the SKIN and EDEMA, known as MYXEDEMA. It may be primary or secondary due to other pituitary disease, or hypothalamic dysfunction. Central Hypothyroidism,Primary Hypothyroidism,Secondary Hypothyroidism,TSH Deficiency,Thyroid-Stimulating Hormone Deficiency,Central Hypothyroidisms,Deficiency, TSH,Deficiency, Thyroid-Stimulating Hormone,Hormone Deficiency, Thyroid-Stimulating,Hypothyroidism, Central,Hypothyroidism, Primary,Hypothyroidism, Secondary,Hypothyroidisms,Primary Hypothyroidisms,Secondary Hypothyroidisms,TSH Deficiencies,Thyroid Stimulating Hormone Deficiency,Thyroid-Stimulating Hormone Deficiencies
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

D004909 Erythrocyte Indices ERYTHROCYTE size and HEMOGLOBIN content or concentration, usually derived from ERYTHROCYTE COUNT; BLOOD hemoglobin concentration; and HEMATOCRIT.

D005319 Fetal Hemoglobin The major component of hemoglobin in the fetus. This HEMOGLOBIN has two alpha and two gamma polypeptide subunits in comparison to normal adult hemoglobin, which has two alpha and two beta polypeptide subunits. Fetal hemoglobin concentrations can be elevated (usually above 0.5%) in children and adults affected by LEUKEMIA and several types of ANEMIA. Hemoglobin F,Hemoglobin, Fetal
D006441 Hemoglobin A Normal adult human hemoglobin. The globin moiety consists of two alpha and two beta chains.
