  • Title: Decreased ratio of serum T3:rT3 in patients with hyperthyroidism.
    Author: Banovac K, Bzik L, Sekso M, Petek M.
    Journal: Endokrinologie; 1978 Apr; 71(2):159-63. PubMed ID: 668639.
    Abstract:
    In 14 hyperthyroid patient serum T4:rT3 ratio was significantly lower (399 +/- 20) than in the control subjects (572 +/- 20; p less than 0.001). A similar pattern was found for serum T3:rT3 ratio. In the hyperthyroid group the ratio was significantly lower (10.5 +/- 0.5) than in the control group (12.5 +/- 0.6; p less than 0.05). The data suggest that in hyperthyroidism the organism might shift conversion of T4 from biologically active T3 to poorly calorigenic rT3. It seems possible that the proportionately increased generation of rT3 than that of T3 may be a defence mechanism of the body, as it was found in systemic illnesses and starvation.
