[The outlook for hormonal therapy in nutrition]

Area of Science:

• Endocrinology
• Metabolic Regulation
• Protein Metabolism

Context:

• Stress significantly impacts the neuro-endocrine system, influencing the balance between anabolism and catabolism.
• Insufficient energetic substrates can exacerbate catabolic states, necessitating a focus on hormonal regulation.
• Understanding these mechanisms is key to developing effective therapeutic strategies.

Purpose:

• To review the endocrine response to stress and its effects on protein metabolism.
• To evaluate current and emerging therapeutic interventions for managing catabolism.
• To assess the clinical viability of hormonal therapies in nutritional support.

Summary:

• Pharmacological inhibition of catabolic hormones (glucagon, catecholamines) has proven ineffective.
• Insulin administration shows controversial results regarding nitrogen balance.
• Anabolic steroids (nandrolone, stanolone, methenolone) promote protein anabolism with minimal androgenic effects.
• Emerging therapies involving growth hormone (GH) and insulin-like growth factor 1 (IGF-1) show promising results but require further clinical validation.
• Current advanced therapies are in experimental stages and not yet accepted for routine clinical or nutritional practice.

Impact:

• Identifies limitations of current therapeutic approaches for catabolic states.
• Highlights the potential of novel hormonal therapies like GH and IGF-1.
• Emphasizes the need for further research and clinical trials before widespread adoption of experimental treatments.
• Provides insights into the complex interplay between stress, hormones, and protein metabolism.
