    Chronic heavy alcohol consumption in male brewery workers did not affect hypothalamic-pituitary-adrenocortical (HPA) function. Despite some physical changes, HPA axis function remained normal in these long-term heavy drinkers.

    Area of Science:

    • Endocrinology
    • Occupational Health
    • Alcohol Research

    Background:

    • Chronic heavy alcohol intake is a significant public health concern.
    • Potential endocrine disruptions associated with long-term alcohol abuse require further investigation.
    • The hypothalamic-pituitary-adrenocortical (HPA) axis is a key regulator of the stress response and can be influenced by various factors.

    Purpose of the Study:

    • To evaluate the impact of chronic heavy alcohol consumption on HPA axis function in male brewery workers.
    • To assess whether long-term alcohol intake affects cortisol levels and the HPA axis's response to dexamethasone suppression.
    • To investigate potential correlations between physical signs suggestive of Cushingoid features and HPA function in this cohort.

    Main Methods:

    Related Experiment Videos

  • Assessed HPA function in 15 male brewery workers with a history of >= 100g daily alcohol intake for at least 10 years.
  • Measured free urinary cortisol during baseline and dexamethasone suppression tests (0.5 mg 6-hourly).
  • Evaluated physical characteristics, including moon face and buffalo hump, for Cushingoid stigmata.

    • Main Results:

    • All subjects exhibited normal basal urinary cortisol excretion.
    • Dexamethasone suppression of cortisol was normal in all but one participant.
    • Four subjects displayed Cushingoid-like facial features; two also had buffalo humps, with no correlation to HPA function metrics.

    Conclusions:

    • Chronic alcohol intake, at the levels studied, does not appear to significantly alter HPA axis function.
    • The observed Cushingoid stigmata in some individuals were not directly linked to HPA axis dysfunction in this cohort.
    • Further research may be needed to explore other potential health impacts of chronic heavy alcohol consumption unrelated to HPA axis regulation.
