Adrenal glands were found to be enlarged in patients with multiple sclerosis (MS). This finding in MS suggests potential links to excessive glucocorticoid secretion and altered immune responses.

Area of Science:

  • Endocrinology
  • Neurology
  • Pathology

Background:

  • Patients with multiple sclerosis (MS) and depression exhibit glucocorticoid feedback insensitivity.
  • Elevated glucocorticoid levels and enlarged adrenal glands are observed in depressed individuals.
  • This study is the first to investigate adrenal gland size in MS patients.

Purpose of the Study:

  • To ascertain if adrenal glands are enlarged in individuals diagnosed with multiple sclerosis (MS).
  • To explore the potential implications of chronic high glucocorticoid levels in MS on steroid response.

Main Methods:

  • A retrospective postmortem analysis was conducted.
  • Adrenal gland size was compared between MS patients and those with other neurological (amyotrophic lateral sclerosis) and non-neurological (acute myocardial infarction) diseases.

  • Data from autopsy cases at a tertiary care hospital were utilized.
  • Main Results:

    • Adrenal glands were significantly enlarged in MS patients compared to controls.
    • MS patients' adrenal glands were 36% larger than those with amyotrophic lateral sclerosis, with similar body weights.
    • The adrenal-to-body weight ratio was 40% greater in MS patients than in those who died from acute myocardial infarction.

    Conclusions:

    • The observed increase in adrenal gland size in MS patients may facilitate excessive glucocorticoid secretion during stress.
    • Altered glucocorticoid secretion could play a role in the immune dysregulation seen in MS.
