Assessment of thyroid function in chronic alcoholics.

G Kallner

    Acta Medica Scandinavica
    |January 1, 1981
    PubMed
    Summary

    Chronic alcoholics may show hyperthyroid symptoms, but thyroid function can be preserved. A specific thyroid hormone test (T3) after TRH stimulation helps evaluate euthyroid status in these individuals.

    Area of Science:

    • Endocrinology
    • Internal Medicine
    • Toxicology

    Background:

    • Clinical symptoms in chronic alcoholics can resemble hyperthyroidism.
    • Diagnostic challenges exist due to contradictory findings in thyroid function tests.
    • Alcoholism can affect thyroid hormone levels and regulation.

    Purpose of the Study:

    • To investigate thyroid function in chronic alcoholics presenting with sympathoadrenal symptoms.
    • To evaluate the utility of the thyrotropin-releasing hormone (TRH) test in assessing thyroid status in this population.
    • To determine if specific thyroid hormone measurements can accurately reflect euthyroid function despite alcohol's effects.

    Main Methods:

    • Study included ten chronic alcoholics with sympathoadrenal system symptoms.
    • Thyroid Stimulating Hormone (TSH) and Triiodothyronine (T3) levels were measured.
    • TRH stimulation test was performed with measurements at 120 minutes post-stimulation.

    Main Results:

    • A significant increase in T3 levels at 120 minutes post-TRH stimulation was observed (p < 0.01).
    • Some participants exhibited a blunted TSH response (increment < 3 mU/l).
    • Despite generally low basal T3 levels, the post-TRH T3 increase suggests preserved thyroid function.

    Conclusions:

    • T3 determination at 120 minutes after TRH stimulation is a crucial parameter for evaluating euthyroid function in chronic alcoholics.
    • This method helps differentiate true thyroid dysfunction from alcohol-induced alterations.
    • Preserved thyroid function can be identified even with suppressed TSH response in chronic alcoholics.
