Effectiveness and tolerability of citalopram for the treatment of depression and anxiety disorders in children and adolescents: an open-label study.

To assess the effectiveness and tolerability of citalopram for the acute treatment of children and adolescents suffering from depression and/or anxiety disorders. As much as 78 outpatients, aged 7-18 years with a diagnosis of depressive and/or anxiety disorder, completed an 8-week open trial with citalopram (20-40 mg/day). Outcome, side effects and suicidality were assessed weekly to bi-weekly using appropriate rating scales. At endpoint 56% of subjects were found to be responders (Clinical Global Impression-Improvement [CGI-I] Scale

Serotonin transporter polymorphism (5-HTTLPR) and citalopram effectiveness and side effects in children with depression and/or anxiety disorders.

OBJECTIVE: The aim of this study was to examine the association between polymorphism in the serotonin transporter gene and citalopram effectiveness and side effects in children and adolescents with major depressive disorder (MDD) and/or anxiety disorders. METHODS: Outpatients, aged 7- 18 years with a Diagnostic and Statistical Manual of Mental Disorders, 4th edition, text revision (DSM-IV-TR) MDD and/or anxiety disorder were treated in an 8-week open trial with 20-40 mg/day of citalopram. Subjects were genotyped with respect to short (s) versus long (l) forms of the 5-HTTLPR polymorphism of the serotonin transporter, and the relationship between genotype and outcome and side effects was assessed. RESULTS: Subjects with 5-HTTLPR ss genotype showed a less vigorous response with regard to depressive symptoms measured by the Children's Depression Rating Scale-Revised (CDRS-R) scores over time compared to subjects with sl/ll genotypes (beta = 0.67, z = 2.02, p = 0.04). In addition, the 5-HTTLPR ss group exhibited lower rates of agitation compared to those with sl/ll genotype (6.3% vs. 32.8%, p = 0.05). Also, subjects with 5-HTTLPR ss genotype had consistently higher scores of suicidality at each week compared to the sl/ll group (beta = 0.76, z = 2.04, p = 0.04) as measured by item number 13 of the CDRS-R. CONCLUSIONS: The 5-HTTLPR ss genotype was associated with a poorer clinical response with regard to depressive symptoms as well with fewer reports of agitation. The 5-HTTLPR polymorphism may be a genetic marker of response to citalopram in children and adolescents with depression and/or anxiety.

Patients with schizophrenia or schizoaffective disorder who receive multiple electroconvulsive therapy sessions: characteristics, indications, and results.

BACKGROUND: While electroconvulsive therapy (ECT) has been used for many years, there is insufficient research regarding the indications for continuation/maintenance (C/M)-ECT, its safety and efficacy, and the characteristics of patients with schizophrenia or schizoaffective disorder who receive multiple ECT sessions. The aims of this study were to characterize a series of patients who received 30 ECT sessions or more, to describe treatment regimens in actual practice, and to examine the results of C/M-ECT in terms of safety and efficacy, especially the effect on aggression and functioning. METHODS: We performed a retrospective chart review of 20 consecutive patients (mean age 64.6 years) with schizophrenia (n=16) or schizoaffective disorder (n=4) who received at least 30 ECT sessions at our ECT unit, and also interviewed the treating physician and filled out the Clinical Global Impression-Severity, Global Assessment of Functioning, and the Staff Observation Aggression Scale-Revised. RESULTS: Patients received a mean of 91.3 ECT sessions at a mean interval of 2.6 weeks. All had been hospitalized for most or all of the previous 3 years. There were no major adverse effects, and cognitive side effects were relatively minimal (cognitive deficit present for several hours after treatment). We found that ECT significantly reduced scores on the Staff Observation Aggression Scale-Revised subscales for verbal aggression and self-harm, and improved Global Assessment of Functioning scores. There were reductions in total aggression scores, subscale scores for harm to objects and to others, and Clinical Global Impression-Severity scores, these were not statistically significant. CONCLUSION: C/M-ECT is safe and effective for chronically hospitalized patients. It improves general functioning and reduces verbal aggression and self-harm. More research using other aggression tools is needed to determine its effects and to reproduce our findings in prospective and controlled studies.
