Stress polycythemia--a pathophysiologic study.

M K El-Yousef, W E Bakewell

    Southern Medical Journal
    |May 1, 1975
    PubMed
    Summary
    This summary is machine-generated.

    Chronic stress in Gaisböck syndrome patients leads to reduced REM sleep, decreased nocturnal antidiuretic hormone (ADH)-like activity, and subsequent water loss, causing blood volume changes.

    Area of Science:

    • Endocrinology
    • Sleep Medicine
    • Hematology

    Background:

    • Gaisböck syndrome, also known as stress polycythemia, is characterized by elevated red blood cell mass.
    • The underlying mechanisms, particularly the role of stress and sleep, require further elucidation.

    Purpose of the Study:

    • To investigate the potential link between chronic stress, REM sleep alterations, and nocturnal antidiuretic hormone (ADH)-like activity in patients with Gaisböck syndrome.

    Main Methods:

    • Case study of two patients diagnosed with Gaisböck syndrome.
    • Assessment of chronic stress levels, REM sleep patterns, and nocturnal ADH-like activity.

    Main Results:

    • Both patients exhibited chronic stress, reduced REM sleep, and decreased nocturnal ADH-like activity.

  • This led to significant nocturnal water loss and contributed to the observed blood volume changes.

    • Conclusions:

    • Reduced REM sleep secondary to chronic stress may decrease nocturnal ADH-like activity, causing water loss and blood volume changes in Gaisböck syndrome.
    • Further research is needed to explore other potential contributing factors.
