Predicting the response of depressed patients to biological treatment: the dexamethasone suppression test versus clinical judgement
ED Myers
North Staffordshire Health District.
A dexamethasone suppression test (DST) was carried out in a heterogeneous
sample of 174 depressed patients. In a subsample of 130 patients in whom
biological antidepressive treatment had been commenced either because of an
initial clinical judgement of 'endogenicity' or because of subsequent
evidence of DST non-suppression, the response to treatment was globally
assessed. The results showed no significant differences between the two
groups in the numbers of patients responding favorably to treatment. The
positive predictive value of DST non-suppression for a favourable response
was no higher than that of clinical judgement, and there was little
difference between the sensitivity and specificity of the two predictors.
