The SSRIs drug Fluoxetine, but not the noradrenergic tricyclic drug Desipramine, improves memory performance during acute major depression. Predictive value of pharmacological activity for the relative efficacy of antidepressant drugs. Meta-regression analysis. Paroxetine and fluoxetine effects on mood and cognitive functions in depressed nondemented elderly patients. A randomized effectiveness trial of brief cognitive-behavioral therapy for depressed adolescents receiving antidepressant medication. A double-blind comparison of sertraline and fluoxetine in depressed elderly outpatients. Different gender response to serotonergic and noradrenergic antidepressants. A comparative study of the efficacy of citalopram and reboxetine. Psychotherapy alone and combined with pharmacotherapy in the treatment of depression.
Accumulating evidence suggests that noradrenergic and serotonergic drugs are equally effective in ameliorating the depressive symptoms of major depression. Major depression is associated also with memory impairments, but the comparative effects of the antidepressant drugs on memory are not clear. We previously found that serotonergic neurotransmission is of particular importance for some aspects of episodic memory. We set out to test whether treatment with the selective serotonergic drug Fluoxetine (Prozac) would be advantageous in this respect over treatment with the selective noradrenergic tricyclic antidepressant drug Desipramine (Deprexan). Seventeen patients with major depressive episode, randomly assigned for treatment with either Fluoxetine (n = 8) or Desipramine (n = 9), were assessed for their clinical situation and for memory performance at the beginning of treatment, after 3 weeks, and after 6 weeks of pharmacological treatment. We found that although clinically both drugs were equally effective, the improvement of memory performance in the Fluoxetine-treated patients was significantly greater compared with that of the Desipramine-treated patients. The results support the role of serotonin in memory. More studies in larger samples of patients are required, but it may be that in cases where memory impairment is a major symptom, it would be beneficial to consider serotonergic antidepressant drugs for treatment. Furthermore, in cases where, for various reasons, the treatment of choice is noradrenergic, it may be worthwhile to consider a supplementary serotonergic drug to improve memory deficits. There is uncertainty about the contribution of specific pharmacological properties to the efficacy of antidepressants.
                To assess whether specific pharmacological characteristics of alternative antidepressants resulted in altered efficacy compared to that of selective serotonin reuptake inhibitors in the treatment of major depression.
                Meta-regression analysis of randomised trials that compare treatment with a selective serotonin reuptake inhibitor and an alternative antidepressant.
                One-hundred-and-five randomised trials were included. None of the factors identified a priori predicted a statistically significant improvement in outcome across the trials.
                This analysis does not provide evidence that antidepressants acting at more than one pharmacological site differ in efficacy from drugs selective for serotonin reuptake in the treatment of major depression. A large proportion of the elderly population complains of depressive symptoms. The ideal antidepressant for these patients, who often suffer from numerous concomitant diseases, should not worsen their cognitive functions and should be free of contraindications.
                To assess the effects of 2 selective serotonin reuptake inhibitors on cognitive functions in elderly depressed patients (ICD-10 criteria), we conducted a double-blind, randomized, parallel-group, multicenter study comparing paroxetine (20-40 mg daily) and fluoxetine (20-60 mg daily) treatment for 1 year. Cognitive performance was evaluated by means of the Buschke Selective Reminding Test, the Blessed Information and Memory Test, the Clifton Assessment Schedule, the Cancellation Task Test, and the Wechsler Paired Word Test; the Hamilton Rating Scale for Depression (HAM-D) and the Clinical Anxiety Scale were administered to assess the course of depressive and anxiety symptoms, respectively.
                242 patients were enrolled (mean +/- SD age = 75.4 +/- 6.6 years). During the study, no deterioration of cognition was observed; on the contrary, most of the tested cognitive functions improved. Good antidepressant efficacy was maintained for over 1 year with both drugs, based on the percentage of responders to treatment (patients achieving a HAM-D total score < 10; 60%). Both drugs showed a good tolerability and safety profile.
                The 2 antidepressants proved to be suitable for the long-term treatment of depression in the elderly and to be devoid of detrimental effects on the tested cognitive functions. To test a collaborative-care, cognitive-behavioral therapy (CBT) program adjunctive to selective serotonin reuptake inhibitor (SSRI) treatment in HMO pediatric primary care.
                A randomized effectiveness trial comparing a treatment-as-usual (TAU) control condition consisting primarily of SSRI medication delivered outside the experimental protocol (n = 75) versus TAU SSRI plus brief CBT (n = 77). Participants were identified by a recent dispense of SSRI medication followed by telephone screening. Adolescents with a diagnosis of major depressive disorder (n = 152) were enrolled. The CBT program employed cognitive restructuring and/or behavioral activation training. Therapists consulted with prescribing pediatricians to improve medication adherence.
                Through 1-year follow-up, the authors found CBT advantages on the Short Form-12 Mental Component Scale (p = .04), reductions in TAU outpatient visits (p = .02), and days' supply of all medications (p = .01). No effects were detected for major depressive disorder episodes; a nonsignificant trend favoring CBT was detected on the Center for Epidemiology Depression Scale (p = .07).
                The authors detected a weak CBT effect, possibly rendered less significant by the small sample and likely attenuated by the unexpected reduction in SSRI pharmacotherapy in the CBT condition. Small, incremental improvements over monotherapy, such as observed in this study, most likely represent the new norm in adolescent depression treatment research. There has been a paucity of well-designed studies comparing selective serotonin reuptake inhibitor (SSRI) medications in the treatment of depression in the elderly. This multicenter study was designed to examine the efficacy and safety of sertraline and fluoxetine in depressed elderly outpatients. A secondary objective was to examine the effects of SSRI treatment on quality of life and cognitive function.
                Two hundred thirty-six outpatients 60 years of age and older who met DSM-III-R criteria for major depressive disorder received 1 week of single-blind placebo before being randomly assigned to 12 weeks of double-blind, parallel-group treatment with flexible daily doses of either sertraline (range, 50-100 mg) or fluoxetine (range, 20-40 mg). Primary efficacy measures consisted of the 24-item Hamilton Rating Scale for Depression and Clinical Global Impressions scale ratings. Secondary outcome assessments included clinician- and patient-rated measures of depression symptoms and factors, cognitive functioning, and quality of life, as well as plasma drug concentrations, which were correlated with clinical response.
                Both drugs produced a similarly positive response on the primary efficacy measures, with 12-week responder rates of 73% for sertraline and 71% for fluoxetine. Sertraline-treated patients showed statistically greater cognitive improvement on several measures. Both drugs were safe and well tolerated.
                Data indicate that both drugs are effective antidepressants for the treatment of depressed elderly outpatients. Differences in cognitive performance effects deserve further investigation. It is well established that depressive disorders are more prevalent in women; however gender differences in the pharmacological response to antidepressants are not a consistent finding in all reports. It is considered that this discrepancy can be explained by the fact that in most clinical trials drug use for comparative purposes is not completely different. In this study gender differences in antidepressant response with citalopram (CTP), a selective serotonin reuptake inhibitor and reboxetine (RBX), a selective noradrenaline reuptake inhibitor were evaluated in a group of young men and premenopausal women.
                Eighty-six depressed patients 18 to 40 years old participated in an 8-week double-blind clinical trial. Subjects were divided in four groups according to sex and treatment assignation: females treated with CTP (n = 25) or RBX (n = 23), and males treated with CTP (n = 19) or RBX (n = 19). Response was determined using HDRS and BDI.
                ANOVA analysis considering change in HDRS scores from baseline to last evaluation found a significant interaction between gender and type of treatment. Females treated with CTP showed a significantly greater response than females treated with RBX, while in men no differences were observed for both drugs.
                Replication using larger sample size and longer treatment periods is required.
                These results support previous findings which show that premenopausal women respond better than men to serotonergic antidepressants. They also support that a plausible interaction between gonadal hormones and serotonin may explain gender differences in antidepressant response. The relative efficacy of psychotherapy and combined therapy in the treatment of depression is still a matter of debate.
                To investigate whether combined therapy has advantages over psychotherapy alone.
                A 6-month randomised clinical trial compared Short Psychodynamic Supportive Psychotherapy (n=106) with combined therapy (n=85) in ambulatory patients with mild or moderate major depressive disorder diagnosed using DSM-IV criteria. Antidepressants were prescribed according to a protocol providing four successive steps in case of intolerance or inefficacy: venlafaxine, selective serotonin reuptake inhibitor, nortriptyline and nortriptyline plus lithium. Efficacy was assessed using the 17-item Hamilton Rating Scale for Depression, the Clinical Global Impression of Severity and of Improvement, and the depression sub-scale of the Symptom Checklist.
                The advantages of combining antidepressants with psychotherapy were equivocal. Neither the treating clinicians nor the independent observers were able to ascertain them, but the patients experienced them clearly.
                The advantages of combining antidepressants with psychotherapy are equivocal.
Available evidence offers weak support to the contention that antidepressants are effective for patients with depression and dementia. However, only four studies are included in the meta-analysis relating to efficacy, and sample sizes are small. Moreover, only two included studies investigated the properties of the more commonly used SSRIs and no studies investigated the properties of newer classes of antidepressants (e.g. selective noradrenergic reuptake inhibitors). This review draws attention to the paucity of research and evidence in this area.
