[Thyroid function in severe non-thyroidal diseases].
The aim of the present study was to find out whether a change in the function of the pituitary-thyroid axis can be revealed in a relatively homogenous group of hematological patients. To clarify this problem serum levels of total-thyroxine and triidothyronine, free-thyroxine and free-triiodothyronine, reverse-triidothyronine and thyrotropin were detected in these patients. The majority of subjects with chronic myelogenous leukemia (in the remission phase) have normal pituitary-thyroid function, however a change in the peripheral metabolism of thyroxine can be revealed. Longitudinal studies in patients with acute myelogenous leukemia indicate that in some cases with the progression of the disease serum TSH and thyroid hormone levels decrease referring to secondary hypothyroidism and in these cases the measurement of serum free-thyroxine content by an analogue tracer method is not recommended. On the basis of the investigational results it is stated that in hematological patients the pituitary-thyroid function is influenced by the phase of illness and by the results of the given treatment.
