Summary of the Proposed Research:

The efficacy of selective serotonin reuptake inhibitors (SSRIs) and selective serotonin and noradrenaline reuptake inhibitors (SNRIs) in treating children and adolescents with depression is a controversial subject, and the impact of age and sex on treatment outcome is unclear. In most studies, patients are divided into age groups according to English nomenclature; children 7-11 years and adolescents 12-18 years, with no respect to pubertal stage or differential maturity between sexes. Little is also known about how individual items on the psychometric scales used in these studies respond to antidepressant therapy and placebo respectively, and if there are differences at baseline between different age groups. We have previously pointed out that in GlaxoSmithKline’s study GSK-BRL-029060/329, there was a significant effect on depressed mood, item 1 from the Hamilton Depression Rating Scale, as also reported by the original authors. Further, we showed that after excluding the youngest patients (<13 years of age), there was also a significant effect on the total score of the HDRS, the main outcome measure used. As SSRIs and SNRIs continue to be routinely used for depression in children and adolescents, the impact of age and sex on the efficacy of these compounds needs to be clarified.
