Zinc metabolism and thyroid status.

W F Bremner, G S Fell

    Postgraduate Medical Journal
    |March 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Patients with thyrotoxicosis exhibit increased urinary zinc excretion compared to euthyroid individuals. This heightened excretion correlates with hyperthyroidism severity, suggesting a link between zinc metabolism and thyroid hormone levels.

    Area of Science:

    • Endocrinology
    • Mineral Metabolism

    Background:

    • Thyrotoxicosis, a condition of excess thyroid hormones, impacts various metabolic processes.
    • Zinc is an essential trace element involved in numerous enzymatic functions.

    Purpose of the Study:

    • To investigate urinary zinc excretion in patients with thyrotoxicosis.
    • To determine the relationship between urinary zinc levels and the severity of hyperthyroidism.

    Main Methods:

    • Comparison of urinary zinc excretion in thyrotoxic patients versus euthyroid controls.
    • Assessment of correlation between urinary zinc and a metabolic severity index.
    • Evaluation of creatinine clearance to rule out its influence.

    Main Results:

    • Urinary zinc excretion was significantly higher in thyrotoxic individuals.

  • The increase in zinc excretion was not attributed to elevated creatinine clearance.
  • A strong positive correlation was observed between urinary zinc levels and hyperthyroidism severity.

    • Conclusions:

    • Thyrotoxicosis leads to increased urinary zinc loss.
    • Urinary zinc excretion may serve as a biomarker for hyperthyroid metabolic activity.
    • Further research is warranted to explore the clinical implications of altered zinc homeostasis in hyperthyroidism.
