    Abstract:
    Patients and/or experimental animals with chronic renal failure have decreased serum levels of triiodothyronine (T3), a hormone well known for its erythropoietic activity. The following studies were designed in order to determine whether this observed abnormality in T3 metabolism is an important contributory factor to the etiology of the anemia of uremia. Groups of rats were made chronically uremic by a standard 5/6 nephrectomy technique and received slightly above physiological doses of T3 either by intermittent S.C. injections (twice daily) or by continuous infusion from intraperitoneally implanted osmotic minipumps. After 2 weeks of such treatment, and despite a normalization of serum T3 levels, there were no significant changes in the hematocrit, individual red cell mass, or serum erythropoietin levels of the uremic animals given T3 compared to control rats. We conclude that (1) the decreased serum T3 levels observed in uremia are not an important contributory factor to the pathogenesis of the anemia, and (2) treatment with replacement doses of T3 does not result in significant improvement of erythropoiesis.
