13 patients with amyotrophic lateral sclerosis (ALS) were treated with intravenous infusion of thyrotropin-releasing hormone (TRH). In 6 patients 2 mg/day of TRH was i.v. given over 2 hours for 10 days. In 7 others 2 mg/day of TRH was continuously infused by means of a pump. An increase of thyroid hormones related to the duration of the treatment was observed. A surprising finding was the onset of prolactin (PRL) response to growth hormone releasing hormone (GHRH), previously absent.

Eight patients with amyotrophic lateral sclerosis received 500 mg TRH by IV infusion, at a progressive rate during 3 hours. Only 3 patients noted subjective improvement of strength. Clinical muscular testing and H response study failed to show any change. Moreover modifications of the prolactin, growth hormone, TSH and T3 serum levels raise a question concerning the tolerance with long term utilization of TRH.

Secretion of prolactin in nine patients with amyotrophic lateral sclerosis and in seven healthy men was investigated with the use of metoclopramide stimulation and bromocriptine inhibition tests. Blood serum prolactin concentration was determined in the basal state and 30, 60 and 120 minutes after oral administration of 10 mg metoclopramide or 2.5 mg bromocriptine. A period of 3 days intervened between testing each drug in the same individual. It was shown that basal prolactin levels in amyotrophic lateral sclerosis patients and the controls did not differ significantly, whereas in the metoclopramide stimulation test seven amyotrophic lateral sclerosis patients showed a very exaggerated response. The mean value of maximal prolactin increment was 1609.90% (SD 456) in comparison with the control group 638.3% (SD 89.7) (p less than 0.01). In the bromocriptine inhibition test the mean value of maximal prolactin percentage decrement was 50.4% (SD 6.1) in amyotrophic lateral sclerosis and 66.5% (SD 5.3) in the controls and this difference was statistically insignificant. These data suggest that exaggerated prolactin response to metoclopramide in amyotrophic lateral sclerosis may be a result of a decreased activity of central dopaminergic neurons.

Thyrotropin-releasing hormone (TRH) causes a variety of thyroidal and non-thyroidal effects, the best known being the feedback regulation of thyroid hormone levels. This was employed in the TRH stimulation test, which is currently little used. The role of TRH as a cancer biomarker is minor, but exaggerated responses to TSH and prolactin levels in breast cancer led to the hypothesis of a potential role for TRH in the pathogenesis of this disease. TRH is a rapidly degraded peptide with multiple targets, limiting its suitability as a biomarker and drug candidate. Although some studies reported efficacy in neural diseases (depression, spinal cord injury, amyotrophic lateral sclerosis, etc.), therapeutic use of TRH is presently restricted to spinocerebellar degenerative disease. Regulation of TRH production in the hypothalamus, patterns of expression of TRH and its receptor in the body, its role in energy metabolism and in prolactin secretion are addressed in this review.
