Objective: To examine the diagnostic status of patients enrolled in the Factors Influencing Depression Endpoints Research (FINDER) study and symptomatic outcomes and baseline characteristics associated with remission 6 months after commencing antidepressant therapy., Method: Status of clinically diagnosed depressed patients was based on self-rated Hospital Anxiety and Depression Scale (HADS) scores. Five diagnostic categories were defined: noncaseness, mixed anxiety-depression (subthreshold depressive and anxious symptomatology), caseness for depression, caseness for anxiety, and caseness for comorbid anxiety-depression. Assessments included the Somatic Symptom Inventory and health-related quality of life (HRQoL) using the Medical Outcomes Study 36-item Short-Form Health Survey. Remission rates (based on HADS noncaseness for both depression and anxiety) and their associations with baseline characteristics were investigated. Patients were enrolled between May 2004 and September 2005., Results: Of the 3,353 patients enrolled, 66.4% met the HADS criteria for probable depressive disorder and 74.1% met the HADS criteria for probable anxiety disorder. Somatic symptom severity (painful and nonpainful) was highest and HRQoL was lowest in the comorbid anxiety-depression group. After 6 months, remission rates were 50.2% for caseness for depression, 40.4% for caseness for anxiety, and 40.6% for caseness for comorbid anxiety-depression. A lower number of previous depressive episodes, shorter current episode duration, lower painful and nonpainful somatic symptom scores, being married, a higher educational level, and working for pay were most consistently associated with higher remission rates., Conclusions: Physicians do not always differentiate between anxiety and depressive symptoms when making a clinical diagnosis of depression. At baseline, most enrolled patients had significant emotional depressive and anxious symptoms, as well as significant nonpainful and painful somatic symptomatology, and these factors were associated with outcome.

Objective: To investigate the relationship between the characteristics of somatic symptoms and depression severity, quality of life (QOL), and health resources utilization in patients with major depressive disorder (MDD) in primary care setting., Method: This cross-sectional, nationwide epidemiologic study, carried out in 1150 primary care patients with DSM-IV-defined MDD, evaluated the characteristics of somatic symptoms by means of the Standardized Polyvalent Psychiatric Interview. Depression severity and QOL were evaluated by means of the Zung Self-Rating Depression Scale (SDS) and the Physical and Mental Component Summaries of the Medical Outcomes Study 12-item Short-Form Health Survey. Health resources utilization was measured in terms of doctor consultations and hospitalizations. The associations were assessed by means of adjusted analyses. The study was carried out from April 2004 to July 2004., Results: Disability associated with somatic symptoms and number of somatic symptoms were strongly associated with increased depression severity (2.45 and 0.29 increase in SDS score, respectively) and health resources utilization (odds ratios of 1.42 and 1.04, respectively). Associated disability, frequency, and persistence during leisure time of somatic symptoms were strongly associated with poorer QOL. In contrast, we found a weaker relationship between duration and intensity of somatic symptoms and depression severity, QOL, and health resources utilization., Conclusions: Of the studied somatic symptom characteristics, somatic symptom-associated disability and number of somatic symptoms are strongly associated with increased depression severity and health resources utilization, as well as with decreased QOL. Our results may help physicians identify relevant characteristics of somatic symptoms to more effectively diagnose and treat depression in primary care patients.

Objective: To compare 2 methods of switching selective serotonin reuptake inhibitor (SSRI) non-responders or partial responders to duloxetine., Method: Adult outpatients with DSM-IV major depressive disorder, a Hamilton Rating Scale for Depression (HAM-D(17)) total score of >or= 15, and a Clinical Global Impressions-Severity of Illness score of >or= 3 despite at least 6 weeks of SSRI treatment were randomly assigned to either abrupt discontinuation of SSRI immediately followed by initiation of duloxetine (direct switch [DS]; N = 183) or tapered discontinuation of SSRI over 2 weeks and simultaneous administration of duloxetine (start-taper switch [STS]; N = 185). Efficacy, safety, and tolerability outcomes associated with these 2 switch methods were compared following switch and after 10 weeks of duloxetine treatment. The study was conducted from August 2004 to March 2006., Results: There was a significant improvement in depressive symptom severity in both switch groups as measured by mean change in HAM-D(17) total score (p
