[Peripheral thyroid function and TRH-TSH test in patients with acromegaly].

In 11 patients with acromegaly the peripheral thyroid hormones were determined and a TRH-TSH-test was carried out. Depending on the result of the determination of the growth hormone the patients were classified into two groups (active and inactive acromegaly). The serum thyroxin level and the T3-binding capacity were normal. Only in a few patients decreased triiodotyronine levels were found. Independent of the degree of activity of the acromegaly positive as well as negative TRH-TSH-tests were found. The struma in patients with acromegaly which is frequently to be observed seems to be in a causal connection with this disease. The examination show altogether that the control of the function of the thyroid gland and the TRH-TSH-test do not deliver an essential contribution for the diagnostics of acromegaly itself.
