Obsessive-compulsive disorder: an open-label pilot trial of escitalopram.

INTRODUCTION: Selective serotonin reuptake inhibitors are considered the most effective and well-established pharmacotherapy for the treatment of obsessive-compulsive disorder (OCD), a chronic and disabling condition. However, approximately 40% of patients do not have a significant improvement, suggesting that new medications are needed. This study was designed to investigate the treatment response to escitalopram in OCD patients. METHODS: This open-label study involved 11 adult OCD outpatients diagnosed with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I Disorders. Data were collected and the treatment response was assessed by an experienced psychiatrist by using the Yale-Brown Obsessive-Compulsive Scale. Subjects received escitalopram 30 mg/day for 12 weeks starting at 10 mg/day. Dosage adjustments were made within 2 weeks, depending on the tolerability of the patient. RESULTS: Six of the 11 patients (54.5%) presented a reduction of at least 40% in the baseline total Yale-Brown Obsessive-Compulsive Scale scores. CONCLUSION: Despite the small sample size and the open-label nature of this trial, these data suggest that escitalopram may be a useful option for patients with OCD.

Effectiveness of antidepressants in the treatment of major depressive disorder in Latin America.

Objective. Painful physical symptoms occur frequently in patients with major depressive disorder (MDD), and although numerous studies report the effect of antidepressants on emotional aspects of depression, few focus on their effect on physical symptoms. This observational study was conducted, in a clinical practice setting, to determine antidepressant treatment decisions and their outcome on the physical and emotional symptoms of MDD. Methods. Patients with a mean score ≥2 for pain-related items on the Somatic Symptom Inventory (SSI) were classified with painful physical symptoms (PPS +) and differentiated from the remaining patients (PPS -). Severity of depression and physical pain were determined using the 17-item Hamilton Depression Rating Scale (HAMD17) and Clinical Global Impressions of Severity Scale (CGI-S), and Visual Analog Scale (VAS), respectively. Results. At baseline, 72.6% of patients were PPS+. Compared to PPS- patients, PPS +patients were, on average, significantly more depressed at baseline (mean difference [95% CI]: HAMD17 4.6 [3.6, 5.5] and CGI-S 0.3 [0.2, 0.4]; all p<0.0001), and remained more depressed and in greater pain at endpoint (HAMD17p=0.0074, CGI-S P =0.0151, and VAS P <0.0001). In addition, fewer PPS+ patients (65.8%) achieved remission (total HAMD17≤7) compared to PPS- patients (74.6%, P =0.0180). Conclusions. Painful physical symptoms are prevalent in MDD patients, highlighting the importance of addressing both the physical and emotional symptoms of depression.
