Unequal concentrations of free T3 and free T4 after ultrafiltration.
To the Editor: Ultrafiltration is a standard method for separating free T3 and free T4 from serum proteins and proteinbound hormone (1, 2 ). It is expected that free T3 and free T4 in aqueous solutions will accompany water as water moves across semipermeable membranes, a process that results in equal concentrations of free T3 and free T4 in the aqueous solutions on opposite sides of semipermeab...
متن کاملSerum free triiodothyronine (T3) to free thyroxine (T4) ratio in treated central hypothyroidism compared with primary hypothyroidism and euthyroidism.
UNLABELLED The standard treatment of hypothyroidism (central and primary) consists of thyroxine (T4) administration alone. However, the normal thyroid gland produces a small proportion of triiodothyronine (T3) directly into the circulation. AIM We aimed to study the free T3 to free T4 ratio in treated central hypothyroidism compared with euthyroidism and treated primary hypothyroidism. METH...
متن کاملEuthyroid patient with elevated serum free thyroxine.
A 32-year-old female patient presented complaining of increased flushing, perspiration and heat intolerance of 3 months’ duration. Medical history included idiopathic thrombocytopenic purpura of 4 years’ duration, which had been treated by splenectomy after failed immunosuppression with prednisone and azathioprine and was currently in remission. On examination, she was found to be clinically eu...
متن کاملHeritability of serum TSH, free T4 and free T3 concentrations: a study of a large UK twin cohort.
OBJECTIVE Thyroid hormone action influences many metabolic and synthetic processes, but the degree of regulation attributed to genes and environmental factors affecting normal variation remains controversial. DESIGN We investigated the magnitude of the genetic and environmental determination of serum concentrations of free (f) T3, fT4, TSH and the fT4 x TSH product and their variation, in a l...
متن کاملFree Triiodothyronine and Cholesterol Levels in Euthyroid Elderly T2DM Patients
Thyroid function regulates lipid metabolism. Despite the fact that T2DM is more prevalent in the elderly, often associates with thyroid dysfunction and increases cardiovascular risk both per se and via high TC and LDL-C levels, the association of the latter with FT(3) and FT(4) levels has not yet been fully investigated in T2DM. While trying to fill this gap in 296 elderly outpatients with T2DM...
