    Summary

    Thyroid surgery for toxic goiter alters pituitary-hypothalamic-thyroid function. Researchers identified four distinct TSH response groups post-operation, indicating significant system changes.

    Area of Science:

    • Endocrinology
    • Thyroidology
    • Neurosurgery

    Background:

    • Diffuse toxic goiter is a common endocrine disorder.
    • Subtotal thyroid resection is a standard surgical treatment.
    • Postoperative thyroid function requires careful monitoring.

    Purpose of the Study:

    • To evaluate the pituitary-hypothalamic-thyroid system's function one month after subtotal thyroid resection for diffuse toxic goiter.
    • To characterize the thyroid-stimulating hormone (TSH) response to thyrotropin-releasing hormone (TRH) in these patients.

    Main Methods:

    • Twenty-five patients underwent subtotal thyroid resection for diffuse toxic goiter.
    • TSH and TRH testing was performed one month post-surgery.
    • Patients were categorized based on their TSH response to TRH.

    Main Results:

    • A broad spectrum of TSH responses to TRH was observed.
    • Four distinct groups were identified, showing decreasing or paradoxical TSH responses.
    • No correlation was found between TSH response patterns and preoperative thyroid status, disease duration, or autoimmune markers.
    • Most patients exhibited significant alterations in pituitary-hypothalamic-thyroid system function.

    Conclusions:

    • Subtotal thyroid resection for diffuse toxic goiter leads to substantial changes in pituitary-hypothalamic-thyroid axis function.
    • The TSH response to TRH is heterogeneous post-operatively, suggesting varied individual adaptations.
    • Further research is needed to understand the long-term implications of these functional changes.
