TRH by slow, continuous infusion: an antidepressant?

A slow, continuous infusion of 1000 mug TRH (thyrotropin releasing hormone) over a period of 4 h had a very faint and diffuse short-lasting beneficial effect on a group of 10 depressive patients. This was assessed in a double blind cross-over trial with placebo. The effect was of no therapeutic value. No difference was found between the depressive patients and a control group of normal subjects in TSH response, T3 resin uptake, T4 or free thyroxine index values as a consequence of the TRH infusion.

Glucose tolerance and insulin release, a mathematical approach. II. Approximation of the peripheral insulin resistance after oral glucose loading.

A parameter of peripheral insulin activity (A = 10(4)/IpGp) can be obtained after oral glucose loading by simple calcuation using insulin and glucose levels at the glucose peak. In combination with a glucose-independent parameter of beta-cell function (CIR = 100. I/G(G-70) a parameter of glucose tolerance (GT = A-CIR) is defined. The parameters allow one to separate the contributions of beta-cell function and peripheral insulin resistance to the glucose tolerance observed after glucose loading. Examples, based on the literature and our own work, illustrate the increase of A and GT by cortisone acetate premedication as well as long-term oral contraceptive medication.

Thyrotropin releasing hormone (TRH) as a possible quick-acting but short-lasting antidepressant.

In a double reversal design the potency of thyrotropin releasing hormone (TRH) (500 mug intravenously) as a quick-acting antidepressive agent was evaluated. A first injection did seem to give rise to a very slight short-lasting effect, though this could not be ascertained clearly. There were no visible effects after a second injection. The thyroid stimulating hormone (TSH) response curve after TRH administration in the depressive patients group was blunted in comparison with that in a matched control group of normals.
