The influence of the use of estrogen replacement therapy (ERT) on the antidepressant response to sertraline of 127 women over 60 years old was evaluated with data from two multicenter trials. At endpoint, sertraline-treated women taking ERT had significantly greater global improvement and quality of life than those not receiving ERT. Modest improvements were also observed in anxiety symptoms and cognitive functioning. The results provide preliminary evidence that ERT use (without progesterone) in older depressed women may augment the antidepressant response to sertraline in terms of quality of life and general improvement.

St. John's wort is widely used as an herbal remedy for depression. Although its mechanism of action remains unknown, some evidence suggests that St. John's wort might act via brain serotonin (e.g., as a serotonin reuptake inhibitor). To determine whether St. John's wort affects the central serotonergic system, we monitored the discharge rate of serotonin-containing neurons in the dorsal raphe nucleus of awake cats following systemic administration of two clinical preparations of St. John's wort, Jarsin 300 (15-600 mg/kg, p.o.) and Hyperforat (0.5-4.0 ml, i.v.). Both preparations were found to have no effect on neuronal activity. This contrasts sharply with the action of fluoxetine and sertraline (2 mg/kg, p.o.), two selective serotonin reuptake inhibitors (SSRIs), which markedly depressed neuronal activity by increasing the synaptic availability of serotonin at inhibitory somatodendritic 5-HT(1A) autoreceptors. The failure of St. John's wort to depress neuronal activity cannot be attributed to an impairment of the 5-HT(1A) autoreceptor mechanism, since pretreatment with Jarsin 300 (300 mg/kg, p.o.) did not alter the responsiveness of serotonergic neurons to the 5-HT(1A) agonist 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT) (10 microg/kg, i.v.). Overall, these findings indicate that the mode of action of St. John's wort is different from that of conventional antidepressant drugs, which elevate brain serotonin and evoke negative feedback control of serotonergic neurons.

The authors describe the use of three new antidepressants: Sertralilne, Paroxetine and Venlafaxine in treating Posttraumatic Stress Disorder and symptoms of Depression in adult Bosnian refugees victims of ethnic cleansing. 32 Bosnian refugees with PTSD and symptoms of Depression presenting for treatment of the mental health consequences of surviving ethnic cleansing, participated in a case series study. All subjects completed open trials of Sertraline (15), Paroxetine (12) or Venlafaxine (5), with standard clinical doses. Overall, Sertraline and Paroxetine yielded statistically significant improvement at 6 weeks in the total PTSD symptom severity, in each symptom cluster, in Beck Depression Inventory and in Global Assessment of Functioning. Venlafaxine produced statistically significant improvement at 6 weeks in the total PTSD symptom severity, in each symptom cluster and in Global Assessment of Functioning but did not yield significant improvement in symptoms of depression and had a high rate of side effects.
