Adrenal or Gonadal Hyperfunction

Conditions:

• Seen in conditions like adrenal tumors, Cushing’s syndrome, or polycystic ovarian syndrome (PCOS).

Excess Androgen Production:

• In both sexes, high androgen excretion may be a sign of endocrine dysregulation.

Stress or Infection:

• Intense physiologic stress—involving inflammation or systemic autoimmune reactions—can sometimes alter adrenal steroid metabolism and elevate ketosteroid production.

‍

Adrenal Insufficiency & Hypogonadism

Adrenal Insufficiency:

• Diminished steroid hormone output, as in Addison’s disease or hypopituitarism, results in reduced excretion.

Hypogonadism:

• In some cases, diminished production from the gonads leads to low levels.

Age-Related Hormonal Considerations

Prepubertal Children:

• Naturally low levels are expected; an unexpected rise might signal precocious puberty or an adrenal tumor.

Adults:

• Persistently high values may indicate marked androgen overproduction, while low values suggest an overall lack of steroid synthesis.

Adrenal Corticosteroid Production and Regulation

All these markers are part of the adrenal corticosteroid system, which is regulated by the hypothalamic–pituitary–adrenal (HPA) axis:

• 11‑Plasma Oxycorticosteroids: These reflect adrenal glucocorticoid production (such as cortisol and related steroids) measured in blood.
• 17‑Plasma Oxycorticosteroids: These indicate another set of adrenal steroids (often including precursors or androgens) in the blood.
• 17‑Urine Ketosteroids: These are urinary metabolites derived primarily from the 17‑hydroxylated adrenal steroids. They provide an integrated view of adrenal steroid production over time.
• Corticotropin (ACTH): This pituitary hormone stimulates the adrenal cortex to produce these corticosteroids.

In essence, ACTH drives the production of various adrenal hormones, which are then measured in blood (11‑ and 17‑oxy compounds) and metabolized to form ketosteroids excreted in urine. Together, these tests offer a comprehensive picture of adrenal function and HPA axis activity.
