ABSTRACT | Background. There is evidence to indicate that peripheral glucocorticoid receptor (GR) function is reduced in major depression, and a possible molecular explanation for this is the impact of raised pro-inflammatory cytokines. The topical steroid vasoconstriction assay provides a convenient probe of peripheral GR function. The present study sought to assess the sensitivity of peripheral GRs in antidepressant-resistant major depressives and investigate the association between GR sensitivity and circulating plasma cytokines.Method. Nineteen antidepressant-resistant depressives together with age- and sex-matched healthy controls underwent the steroid vasoconstriction assay using three commercial preparations of corticosteroids containing clobetasol propionate 0.05%, betamethasone valerate 0.1%, and clobetasone butyrate 0.05%, corresponding to very potent, potent, and moderately potent steroid creams respectively. The pro-inflammatory cytokines, tumour necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) were measured using enzyme-linked immunosorbent assays. The severity of the depressive episode was assessed using the Hamilton Depression Scale (HAMD).Results. Depressed subjects had a significantly reduced vasoconstriction response across all three strengths of steroid. They also had significantly higher concentrations of TNF-a and IL-6. There was a significant inverse correlation between TNF-alpha concentration and vasoconstriction response and also between the HAMD score and vasoconstriction response.Conclusions. These findings suggest that Cutaneous GR function is abnormal in antidepressant-resistant depression, that circulating TNF-a may play a significant role in this abnormality and that the efficacy of topical steroids in antidepressant-resistant depressives is reduced. | ||
