[The euthyreotic hypotriiodothyroninemia].
In 33 patients with various, mainly severe diseases a subnormal triiodothyronine concentration (T3) and a normal thyroxin concentration (T4) were found. In addition to T3 and T4, the plasma TSH levels and T3 binding capacity were determined. In no case did the patient's history or clinical findings afford evidence of hypothyroidism. Diminished conversion of T4 to T3 is discussed as a possible cause of the inappropriately depressed T3 levels.
