What is the Origin of GHRH-Arginine Test?

This specialized test evolved from earlier, less specific GH stimulation tests, incorporating GHRH following its isolation and synthesis to provide a more direct probe of pituitary function. The addition of Arginine, an amino acid known to suppress somatostatin release and possess independent GH-releasing properties, was introduced to maximize the GH response. This combination significantly improved the test's sensitivity and diagnostic accuracy for AGHD, becoming a clinical gold standard.

What is the Mechanism of GHRH-Arginine Test?

The test relies on two distinct but synergistic pharmacological stimuli to elicit a maximal response. GHRH directly binds to its receptor on pituitary somatotrophs, initiating the synthesis and subsequent release of GH into the circulation. Arginine acts by inhibiting the release of somatostatin, the hypothalamic inhibitory hormone that normally dampens GH secretion, thereby potentiating the GHRH-induced GH pulse. The combined effect provides a powerful stimulus, and a peak GH level below a defined threshold is diagnostic for impaired GH reserve.

GHRH-Arginine Test

Meaning

The GHRH-Arginine Test is a specific, dynamic endocrinological stimulation test utilized clinically to assess the functional capacity of the somatotropic axis, specifically the pituitary gland’s ability to secrete Growth Hormone (GH). This diagnostic procedure is considered a robust method for diagnosing Adult Growth Hormone Deficiency (AGHD) because it bypasses the hypothalamus, directly stimulating the pituitary somatotrophs. It involves the sequential administration of Growth Hormone-Releasing Hormone (GHRH) and the amino acid Arginine, followed by serial measurements of GH levels.
