Human Growth Hormone Replacement Therapy
DESCRIPTION
Human growth hormone (GH, hGH, somatropin or somatotropin) is synthesized in and secreted by the anterior pituitary. GH binds to cell surfaces, eliciting intracellular signals and initiating a phosphorylation cascade. Additionally, GH stimulates the production of insulin-like growth factors, primarily insulin-like growth factor 1(IGF-1). In these ways, GH regulates cell division and protein synthesis for normal growth and metabolic functions. While most active in childhood, GH continues to be secreted in adulthood, influencing important metabolic functions.
Growth hormone deficiency (GHD) occurs in multiple conditions with negative effects on body composition, cardiovascular risk factors and quality of life. Clinical treatment with GH uses recombinant human growth hormone (rhGH).
Examples of preparations of rhGH are: Accretropin™, Genotropin®, Humatrope®, Norditropin®, Nutropin®, Saizen®, Serostim®, Tev-Tropin® and Zorbtive®.

APPLICABLE TENNESSEE STATE MANDATE REQUIREMENTS
Tennessee State law requires coverage of off-label indications of Food and Drug Administration (FDA) approved drugs when the off-label use is relative to life-threatening illnesses, such as cancer, AIDS, and coronary heart disease and recognized in one of the standard reference compendia (As defined in the statute: The United States Pharmacopoeia Drug Information, The American Medical Association Drug Evaluations, & The American Hospital Formulary Service Drug Information) or in the medical literature. This law is applicable to all fully insured members. The law is not applicable to self-funded accounts, but coverage for off-label uses may be provided based on the contractual agreement.
ADDITIONAL INFORMATION
For appropriate dosage information, contraindications, precautions, warnings, and monitoring information, please refer to one of the standard reference compendia (e.g., The American Hospital Formulary Service Drug Information).
Growth hormone stimulation tests involve the use of various agents and combinations of agents including insulin [insulin tolerance test (ITT)], growth hormone–releasing hormone (GHRH), growth hormone-releasing peptide (GHRP), hexarelin, L-dopa and arginine.
In children, GH therapy is typically discontinued when the growth velocity is less that 2 cm per year, when epiphyseal fusion has occurred, or when the height reaches the 5th percentile of adult height.
No controlled studies were found in the published literature that validate the use of human growth hormone therapy for other conditions / diseases.
