This study found no significant differences in cortisol levels among individuals with somatization syndrome, those with both somatization and depression, and healthy controls. However, cortisol

Area of Science:

  • Psychoneuroendocrinology
  • Clinical Psychology
  • Psychiatry

Background:

  • Somatization symptoms frequently co-occur with depression, anxiety, and distress.
  • These psychological states are known to interact with the hypothalamic-pituitary-adrenal (HPA) axis.
  • Understanding the relationship between somatization and HPA axis activity, particularly cortisol, is crucial.

Purpose of the Study:

  • To investigate the relationship between somatization symptoms and cortisol levels.
  • To compare cortisol profiles across groups with somatization syndrome, somatization with major depression, and healthy controls.
  • To explore correlations between cortisol measures and psychological variables.

Main Methods:

  • Seventy-seven participants were categorized into three groups: somatization syndrome, somatization with major depression, and healthy controls.

  • Collected data included salivary cortisol (morning, afternoon, evening), nighttime urinary cortisol, and serum cortisol post-dexamethasone suppression test (DST).
  • Psychological variables assessed were depression, anxiety, somatization, and hypochondriasis.

    • Main Results:

    • Salivary cortisol exhibited typical diurnal variations across all groups.
    • No significant differences in any measured cortisol variables were found between the three groups.
    • Exploratory analyses indicated time-dependent associations between cortisol and psychopathological variables.
    • Dexamethasone suppression test (DST) results correlated with psychological aspects of somatization, not the symptom count.

    Conclusions:

    • Despite the known interaction between somatization, depression, and the HPA axis, direct differences in cortisol levels were not observed.
    • Counteracting effects of somatization and depression might obscure HPA axis dysregulation in combined presentations.
    • The psychological dimensions of somatization, rather than the sheer number of symptoms, showed a relationship with DST results.
