Thyroid disorders significantly impact adrenal glands. This study reveals altered cortisol levels in hyperthyroidism and hypothyroidism, necessitating careful diagnosis and treatment strategies.

Area of Science:

  • Endocrinology
  • Internal Medicine

Background:

  • Thyroid hormones and adrenal function are closely interconnected.
  • Dysregulation of thyroid hormones can lead to secondary effects on the adrenal glands.
  • Cortisol, a key adrenal hormone, plays a vital role in metabolic and immune functions.

Purpose of the Study:

  • To investigate the impact of thyroid disorders on adrenal gland function by measuring total cortisol levels.
  • To analyze the prevalence and patterns of cortisol alterations in hyperthyroid and hypothyroid patients.
  • To understand the physiological mechanisms underlying these observed hormonal changes.

Main Methods:

  • Radioimmunoassays were utilized to measure thyroid hormones and total cortisol.
  • The study included 108 subjects aged 20-52 years diagnosed with thyroid diseases.

  • Cortisol levels were analyzed in relation to hyperthyroid and hypothyroid states.

    • Main Results:

    • Low cortisol levels (80.35 nmol/L) were observed in 4.77% of hyperthyroid subjects.
    • High cortisol levels were found in 3.57% of hyperthyroid subjects (1348.18 nmol/L) and 12.5% of hypothyroid subjects (969.05 nmol/L).
    • Mechanisms include stimulated secretion of inactive metabolites in hyperthyroidism and decreased clearance in hypothyroidism.

    Conclusions:

    • Thyroid disorders are associated with significant alterations in adrenal gland functional activity.
    • These adrenal changes, observed in approximately 10% of patients, can influence diagnosis and therapeutic approaches.
    • Understanding the interplay between thyroid and adrenal function is crucial for comprehensive patient management.
