What is the Origin of Personalized Steroid Clearance?

This term is a synthesis of endocrinology and personalized medicine. 'Personalized' emphasizes the unique biological profile, and 'Steroid Clearance' refers to the hepatic and renal elimination of these lipid-soluble molecules. The clinical relevance grew with advanced testing methods that measure hormone metabolites.

What is the Mechanism of Personalized Steroid Clearance?

Steroid hormones are primarily cleared through a two-phase process in the liver: Phase I hydroxylation by CYP450 enzymes and Phase II conjugation (e.g., glucuronidation, sulfation) by transferase enzymes. Genetic variants in these enzymes, such as UGTs or COMT, can slow down specific clearance steps, leading to an altered metabolite profile. By identifying these specific metabolic rates and bottlenecks, the clinician can implement targeted nutritional support to enhance the efficiency and safety of the clearance process.

Personalized Steroid Clearance

Meaning

Personalized steroid clearance is the clinical practice of assessing and tailoring interventions to optimize an individual’s unique rate and pathway of metabolism for endogenous and exogenous steroid hormones, such as cortisol, estrogen, and testosterone. This individualized approach recognizes that genetic polymorphisms in hepatic enzymes and variations in gut microbiota profoundly affect the half-life and metabolite profile of these hormones. It is essential for managing hormonal therapy and reducing the risk of accumulating potentially harmful metabolites.
