Adrenocortical dysfunction in acute medical illness.

D Drucker, J McLaughlin

    Critical Care Medicine
    |September 1, 1986
    PubMed
    Summary

    In acute illness, the body alters its adrenal response, increasing certain hormone production. This suggests a metabolic shift favoring glucocorticoids over androgens during critical illness.

    Area of Science:

    • Endocrinology
    • Metabolic pathways
    • Critical care medicine

    Background:

    • The adrenal cortex plays a crucial role in the body's response to stress and illness.
    • Hormonal changes during acute illness are complex and not fully understood.
    • Understanding these changes is vital for managing critically ill patients.

    Purpose of the Study:

    • To investigate the adrenocortical steroidogenesis in acutely ill patients.
    • To characterize the specific hormonal shifts in response to adrenocorticotropic hormone (ACTH) stimulation.
    • To determine if acute illness alters the balance between glucocorticoid and androgen synthesis.

    Main Methods:

    • Measurement of basal and ACTH-stimulated levels of 11-deoxycortisol, androstenedione, and dehydroepiandrosterone sulfate (DHEAS).
    • Analysis of hormone ratios, including androstenedione/cortisol and DHEAS/cortisol.
    • Comparison of hormone levels and ratios between acutely ill patients and healthy controls (implied).

    Main Results:

    • Acutely ill patients exhibited higher ACTH-stimulated 11-deoxycortisol and androstenedione levels.
    • Patients showed decreased basal and ACTH-stimulated androstenedione/cortisol and DHEAS/cortisol ratios.
    • These findings indicate a significant alteration in steroid hormone production during acute illness.

    Conclusions:

    • Acute illness induces a notable shift in adrenocortical function.
    • The data suggest a redirection of steroid synthesis away from androgens towards the glucocorticoid pathway.
    • This hormonal adaptation may have implications for patient outcomes and therapeutic strategies in critical care.
