Thyroid hormone conversion affects hypothyroid treatment
Dosing strategies solely based on a TSH definition of euthyroidism neglect the important role of FT3, which has recently emerged as an equally significant parameter in defining thyroid physiology... in cases where an FT3–FT4 dissociation becomes increasingly apparent following dose escalation of l-T4, an alternate treatment modality, possibly T3/T4 combination therapy, should be considered.
Thyroid in heart, metabolism, brain, kidney; vital importance of T3
Thyroid disorders have widespread impact and although subclinical hypothyroidism and low triiodothyronine (T3) syndrome are common they are frequently overlooked in practice.
Low 'normal' free T3 thyroid hormone predicts death in older patients even without overt hypothyroid
Low free T3 thyroid hormone (triiodothyronine, FT3), even without overt hypothyroid and still within most 'normal' reference ranges, predicts death from cardiovascular disease and all causes in people over 65 according to a study just published in The Journal of Clinical Endocrinology & Metabolism.
Anemia and thyroid hormones
In the present study significant associations between free T4 and erythrocyte indices, including haemoglobin concentration, haematocrit and erythrocyte count were demonstrated.
