Hyperthyroidism affects 3.5% of outpatients, with Graves' disease being most common. While medical treatment is preferred for Graves' disease, relapses occur in 30%, often necessitating surgery. For toxic multinodular goitre and toxic adenoma, surgery is the primary treatment.

Area of Science:

  • Endocrinology
  • Internal Medicine
  • Thyroidology

Context:

  • Thyroid diseases represent a significant portion of outpatient endocrinology cases.
  • Hyperthyroidism (HT) prevalence and management practices in an outpatient setting were investigated.
  • Data from 96 hyperthyroid patients over five years were analyzed.

Purpose:

  • To determine the prevalence and causes of hyperthyroidism in an outpatient clinic.
  • To characterize current diagnostic and therapeutic approaches for hyperthyroidism.
  • To evaluate treatment outcomes and relapse rates for different hyperthyroid etiologies.

Summary:

  • Graves' disease (GD) was the most common cause of hyperthyroidism (49%), followed by toxic multinodular goitre (TMNG) and autoimmune HT.
  • Medical treatment, often with levothyroxine, was the initial choice for 92% of GD patients, though 30% relapsed within six months.

  • Surgery was the preferred initial treatment for TMNG (78.5%) and toxic adenoma (TA) (70%).
  • Adverse effects from antithyroid drugs (ATDs) were observed in 4.1% of patients, including agranulocytosis and allergic reactions.

    • Impact:

    • This study highlights the high relapse rate of Graves' disease under medical management, suggesting a need for alternative or more sustained therapeutic strategies.
    • Findings underscore the importance of considering surgical intervention for recurrent GD and as a primary option for TMNG and TA.
    • Understanding treatment patterns and outcomes can inform clinical guidelines and improve patient management for hyperthyroidism.
