Individual residual symptoms and functional impairment in patients with depression.

The aim of treatment of depression is remission of symptoms and functioning. Although there is a relationship between remission of symptoms and remission of functioning, it is not known how individual residual symptoms are related to functioning. Here we report a post-hoc analysis of two studies which treated depressed patients with duloxetine in an open fashion for 10-12 weeks. We evaluated the association of individual residual symptoms and functional impairment in patients who remitted or partially remitted after acute treatment. Logistic regression was used to investigate residual symptoms associated with functional impairment at endpoint. Our results suggest that in partial remitters, the only residual symptom associated with a reduction in the risk of having impaired function was the resolution of painful physical symptoms (PPS). In patients who remitted, the presence of residual core mood symptoms (CMS), particularly in patients without any anxiety, predicted impaired functioning. The resolution of PPS in the presence of residual CMS was associated with less risk of impaired functioning. Our results contribute to understand better the role of specific residual symptoms on functional impairment. To achieve normal functioning, intervention on specific residual symptoms is recommended.

Prognostic factors of improvement in health-related quality of life in atomoxetine-treated children and adolescents with attention-deficit/hyperactivity disorder, based on a pooled analysis.

The objective of this study is to identify prognostic factors of treatment response to atomoxetine in improvement of health-related quality of life (HR-QoL), measured by the Child Health and Illness Profile-Child Edition Parent Report Form (CHIP-CE PRF) Achievement and Risk Avoidance domains, in children and adolescents with attention-deficit/hyperactivity disorder (ADHD). Pooled data from 3 placebo-controlled trials and separate data from 3 open-label trials of atomoxetine in children and adolescents with ADHD were analyzed using logistic regression methods. Based on baseline impairment in the Achievement and/or Risk Avoidance domains (CHIP-CE PRF < 40 points), 2 subsamples of subjects were included. Treatment outcome was categorized as <5 points or ≥5 points increase in the CHIP-CE PRF Achievement and Risk Avoidance domains. Data of 190 and 183 subjects from the pooled sample, and 422 and 355 subjects from the open-label trials were included in the analysis of Achievement and Risk Avoidance domains. Baseline CHIP-CE subdomain scores proved to be the most robust prognostic factors for treatment outcome in both domains, based on data from the pooled sample of double-blind studies and from the individual open-label studies (odds ratios [OR] 0.74-1.56, p < 0.05; OR < 1, indicating a worse baseline score associated with worse odds of responding). Initial treatment response (≥25 % reduction in ADHD Rating Scale scores in the first 4-6 weeks) was another robust prognostic factor, based on data from the open-label studies (OR 2.99-6.19, p < 0.05). Baseline impairment in HR-QoL and initial treatment response can be early prognostic factors of atomoxetine treatment outcome in HR-QoL in children and adolescents with ADHD.

Long-term quality-of-life and functioning comparison of atomoxetine versus other standard treatment in pediatric attention-deficit/hyperactivity disorder.

Psychopharmacological agents were shown to be important for improving the quality of life (QoL) of patients with attention-deficit/hyperactivity disorder (ADHD). A short-term, 10-week study found atomoxetine (ATX) to be effective in improving QoL of ADHD patients. We compared, for the first time, long-term treatment outcomes of ATX and other early standard therapy (OEST, any pharmacological ADHD treatment except ATX) in QoL and functional impairment in pharmacologically naive children/ adolescents in a randomized, controlled, open-label study at 6 and 12 months. Patients received ATX (0.5-1.8 mg/kg per day) or OEST (mainly methylphenidate). Quality of life and functioning were assessed by the Child Health and Illness Profile-Child Edition, Parent Rating Form and the Weiss Functional Impairment Rating Scale-Parent Report. Three hundred ninety-eight patients (79.4% male; mean age, 9.3 years) received study treatment. The Child Health and Illness Profile-Child Edition, Parent Rating Form achievement domain t scores significantly improved from baseline to 6 months from means of 28.0 to 37.1 for ATX and from 28.3 to 40.7 for OEST. Mean t scores at 12 months were 40.0 for ATX and 41.0 for OEST. The Weiss Functional Impairment Rating Scale-Parent Report total score improved from baseline to 6 months in both groups (ATX: mean 1.02 to 0.63; OEST: 0.96 to 0.59). Both treatments were safe with no statistically significant difference in the overall rate of adverse events. Overall, the improvements in QoL and functional impairment observed over time for ATX and OEST were meaningful and stable over the study period of 12 months. Between-group differences were small but sometimes statistically significant, providing the first-time long-term comparative symptomatic and QoL analysis between ATX and OEST.

Fast vs. slow switching from stimulants to atomoxetine in children and adolescents with attention-deficit/hyperactivity disorder.

OBJECTIVE: To compare fast versus slow switching from stimulants to atomoxetine (ATX) in children and adolescents with attention-deficit/hyperactivity disorder (ADHD). METHODS: This was a randomized, controlled, open-label study in 6-16-year-old ADHD patients, previously treated with stimulants and cross-titrated (fast switch, over 2 weeks, or slow switch, over 10 weeks) to ATX because of unsatisfactory response and/or adverse events. Study duration was 14 weeks with an ATX standard target dose of 1.2 mg/kg/day. Primary measure was the change from baseline in the investigator-rated ADHD-Rating Scale (ADHD-RS) at weeks 2 and 10. Secondary measures included Global Impression of Perceived Difficulties (GIPD) and Child Health and Illness Profile-Child Edition (CHIP-CE). RESULTS: The majority of the 111 patients were male (83.8%, n=93) and mean (SD) age was 11.5 (2.38) years. Mean baseline ADHD-RS total score was 36.0 in the fast and 38.0 in the slow group. Adjusted mean change after 2 weeks was -8.1 (-10.1; -6.1) in the fast and -8.0 (-9.9;-6.0) in the slow group (p=0.927), and after 10 weeks -15.0 (-17.4;-12.6) and -14.3 (-16.7;-12.0), respectively, (p=0.692). GIPD scores did not show differences between groups. Significant differences at week 10 were found in the CHIP-CE achievement domain favoring slow (p=0.036) and the comfort domain favoring fast cross-titration (p=0.030). No significant differences were found for adverse events, and differences for systolic blood pressure (BP) and weight were not considered clinically relevant. CONCLUSIONS: ADHD-RS and GIPD scores improved in both switching groups. No clinically relevant differences between fast and slow switching from stimulants to ATX were found.

Observational study on safety and tolerability of duloxetine in the treatment of female stress urinary incontinence in German routine practice.

AIMS: To evaluate the safety and tolerability of duloxetine during routine clinical care in women with stress urinary incontinence (SUI) in Germany, and in particular, to identify previously unrecognized safety issues as uncommon adverse reactions, and the influence of confounding factors present in clinical practice on the safety profile of duloxetine. METHODS: Office-based urologists, gynaecologists and primary care physicians were asked to document women newly started on treatment for moderate to severe symptoms of SUI. Six thousand eight hundred and fifty-four patients from urologist/gynaecologist practices and 5879 primary care patients were assessed. In a two-armed, observational study with parallel 12 week (urologists and gynaecologists) or 24 week (primary care physicians) design, patients were treated with duloxetine or other conservative treatment. The main outcome measure was the occurrence of adverse events (AEs). RESULTS: Baseline characteristics differed slightly between patient groups and studies. Duloxetine doses in most patients were lower than recommended. Overall, AE frequency with duloxetine was lower than in controlled studies (15.9% (95% CI 14.9, 16.9) and 9.1% (95% CI 8.2, 10.0) in the 12 and 24 week treatment groups, respectively), but exhibited a similar qualitative spectrum. In the logistic regression models, the following factors were associated with greater AE risk: investigator specialization (gynaecologist vs. urologist and primary care physician), initial duloxetine dose (80 vs. 20 mg day(-1) ) and use of any concomitant medication. Within the 24 week study, a positive screen for depressive disorder was surprisingly common, but no case of attempted suicide was reported in either study. CONCLUSIONS: Our results from German clinical practice show that women with SUI were often treated with duloxetine doses lower than recommended. This was associated with a low incidence of AEs. Suicide attempts were not reported.

Quality of Life in Depressed Patients in UK Primary Care: The FINDER Study.

OBJECTIVES: To investigate the impact of depression and its treatment on health-related quality of life (HRQoL) in a naturalistic, primary care setting in the UK. METHODS: The Factors Influencing Depression Endpoints Research (FINDER) study was a European, 6-month, prospective, observational study designed to estimate HRQoL in patients with a clinical diagnosis of depression. This paper examines primary care patients recruited in the UK. HRQoL was measured at baseline and at 3 and 6 months after starting antidepressant therapy using the Short Form 36 Health Status Survey and the European Quality of Life-5 Dimensions (EQ-5D). Regression analysis was used to identify baseline and treatment variables independently and significantly associated with HRQoL. Further analyses included the effect of caseness for depression on HRQoL, the effect of moderate/severe pain at baseline on HRQoL, changes in overall pain, pain interference scores, and the use of different antidepressants by pain cohort. RESULTS: A total of 608 patients was recruited from 58 centres and mean HRQoL was significantly below reported population norms at baseline. Most improvement in HRQoL was seen at 3 months for EQ-5D, with small additional improvement at 6 months. Worse HRQoL outcomes at 6 months were associated with higher somatic symptoms score, duration of depression at baseline, and switching within antidepressant classes. Patients meeting the criteria for caseness for depression, or with significant pain at baseline showed less improvement in HRQoL scores at 6 months. CONCLUSION: Patients presenting with depression in primary care show reduced HRQoL compared to population norms. HRQoL improves during antidepressant treatment particularly within the first 3 months. Nonpainful somatic symptoms, socioeconomic factors, depression variables and switching within antidepressant class predict poor HRQoL outcome. Pain is a common symptom in depressed patients and remains after 6 months' treatment. Pain and somatic symptoms should be assessed in all patients with depression in primary care.

Evaluation of the effect of duloxetine treatment on functioning as measured by the Sheehan disability scale: pooled analysis of data from six randomized, double-blind, placebo-controlled clinical studies.

The purpose of this work is to describe the effect of duloxetine on functioning as measured by the Sheehan disability scale (SDS) compared with placebo in patients with major depressive disorder (MDD). Pooled data from six randomized, parallel, double-blind, placebo-controlled duloxetine studies in adult MDD patients were analyzed at the short-term (7-13 weeks) and the long-term (>24 weeks) endpoint. The primary variable was the SDS total score. Secondary variables included functional remission (SDS total ≤ 6) rates, Hamilton rating scale for depression total score, and pain visual analog scale. Analysis of covariance and logistic regression methods were used to assess differences in treatment and identify prognostic baseline factors. In total, 2496 patients (1424 duloxetine; 1072 placebo) were included. The between-treatment difference of -2.52 between duloxetine and placebo in the SDS total score at the short-term endpoint was statistically significant in favor of duloxetine vs. placebo (95% confidence interval: -3.17, -1.87; P < 0.001). The endpoint functional remission rates were 39.5% with duloxetine and 28.7% with placebo. Time since first depression episode, antidepressant pretreatment (yes/no), baseline visual analog scale pain (≤30 / >30 mm), and sex were significant prognostic factors. The effect of duloxetine was maintained at the long-term endpoint. Duloxetine is effective in improving MDD patients' functioning. Further antidepressant studies focusing on functioning would be helpful.

Early reduction in painful physical symptoms is associated with improvements in long-term depression outcomes in patients treated with duloxetine.

BACKGROUND: To investigate the association of the change of painful physical symptoms (PPS) after 4 weeks, with the 6-month treatment outcomes of depressive symptoms in patients treated with duloxetine in clinical practice. METHODS: Multicenter, prospective, 6-month, non-interventional study in adult outpatients with a depressive episode and starting treatment with duloxetine. Depression severity was assessed by the clinician (Inventory for Depressive Symptomatology [IDS-C]) and patient (Kurz-Skala Stimmung/Aktivierung [KUSTA]). Somatic symptoms and PPS were assessed using the patient-rated Somatic Symptom Inventory (SSI) and visual analog scales (VAS) for pain items. Association of change in PPS with outcomes of depressive symptoms was analyzed based on mean KUSTA scores (mean of items mood, activity, tension/relaxation, sleep) and achievement of a 50% reduction in the total IDS-C score after 6 months using linear and logistic regression models, respectively. RESULTS: Of the 4,517 patients enrolled (mean age: 52.2 years, 71.8% female), 3,320 patients (73.5%) completed the study. 80% of the patients had moderate to severe overall pain (VAS > 30 mm) at baseline. A 50% VAS overall pain reduction after 4 weeks was associated with a 13.32 points higher mean KUSTA score after 6 months, and a 50% pain reduction after 2 weeks with a 6.33 points improvement. No unexpected safety signals were detected in this naturalistic study. CONCLUSION: Pain reduction after 2 and 4 weeks can be used to estimate outcomes of long-term treatment with duloxetine. PPS associated with depression have a potential role in predicting remission of depressive symptoms in clinical practice.

The Factors Influencing Depression Endpoints Research (FINDER) study: final results of Italian patients with depression.

BACKGROUND: Factors Influencing Depression Endpoints Research (FINDER) is a 6-month, prospective, observational study carried out in 12 European countries aimed at investigating health-related quality of life (HRQoL) in outpatients receiving treatment for a first or new depressive episode. The Italian HRQoL data at 6 months is described in this report, and the factors associated with HRQoL changes were determined. METHODS: Data were collected at baseline, 3 and 6 months of treatment. HRQoL was measured using components of the 36-item Short Form Health Survey (SF-36; mental component summary (MCS), physical component summary (PCS)) and the European Quality of Life-5 Dimensions (EQ-5D; visual analogue scale (VAS) and health status index (HSI)). The Hospital Anxiety and Depression Scale (HADS) was adopted to evaluate depressive symptoms, while somatic and painful physical symptoms were assessed by using the 28-item Somatic Symptom Inventory (SSI-28) and a VAS. RESULTS: Of the initial 513 patients, 472 completed the 3-month observation and 466 the 6-month observation. The SF-36 and EQ-5D mean (+/- SD) scores showed HRQoL improvements at 3 months and a further smaller improvement at 6 months, with the most positive effects for SF-36 MCS (baseline 22.0 +/- 9.2, 3 months 34.6 +/- 10.0; 6 months 39.3 +/- 9.5) and EQ-5D HSI (baseline 0.4 +/- 0.3; 3 months 0.7 +/- 0.3; 6 months 0.7 +/- 0.2). Depression and anxiety symptoms (HADS-D mean at baseline 13.3 +/- 4.2; HADS-A mean at baseline 12.2 +/- 3.9) consistently decreased during the first 3 months (8.7 +/- 4.3; 7.5 +/- 3.6) and showed a further positive change at 6 months (6.9 +/- 4.3; 5.8 +/- 3.4). Somatic and painful symptoms (SSI and VAS) significantly decreased, with the most positive changes in the SSI-28 somatic item (mean at baseline 2.4 +/- 0.7; mean change at 3 months: -0.5; 95% CI -0.6 to -0.5; mean change at 6 months: -0.7; 95% CI -0.8 to -0.7); in 'interference of overall pain with daily activities' (mean at baseline 45.2 +/- 30.7; mean change at 3 months -17.4; 95% CI -20.0 to -14.8; mean change at 6 months -24.4; 95% CI -27.3 to -21.6) and in 'having pain while awake' (mean at baseline 41.1 +/- 29.0; mean change at 3 months -13.7; 95% CI -15.9 to -11.5; mean change at 6 months -20.2; 95% CI -22.8 to -17.5) domains. The results from linear regression analyses showed that the antidepressant switch within classes was consistently associated with a worsening in SF-36 MCS, EQ-5D VAS and HSI compared to non-switching treatment. Furthermore, between-group antidepressants (AD) switch was associated with a worse SF-36 MCS and EQ-5D HSI. MCS (P = 0.028), PCS (P = 0.036) and HSI (P = 0.002) were inversely related to the number of each previous additional depressive episode. PCS (P = 0.009) and HSI (P = 0.005) were also less improved in patients suffering from a chronic medical condition. Moreover, PCS (P = 0.044) and EQ-5D VAS (P < 0.0001) worsening was consistently associated with the presence of a psychiatric illness in the 24 months before baseline. For every additional point on the SSI-somatic score and on the overall pain VAS score at baseline, HSI score were on average 0.062 (P < 0.001) and 0.001 (P = 0.005) smaller, respectively. CONCLUSIONS: After starting AD treatment, HRQoL improvements at 3 and 6 months were observed. However, several factors can negatively influence HRQoL, such as the presence of somatic and painful symptoms, the presence of any chronic medical condition or previous psychiatric illness.

Cost-effectiveness of duloxetine: the Stress Urinary Incontinence Treatment (SUIT) study.

OBJECTIVE: To assess the cost-effectiveness of duloxetine compared with conservative therapy in women with stress urinary incontinence (SUI). METHODS: Cost and outcome data were taken from the Stress Urinary Incontinence Treatment (SUIT) study, a 12-month, prospective, observational, naturalistic, multicenter, multicountry study. Costs were assessed in UK pound and outcomes in quality adjusted life years using responses to the EuroQol (EQ-5D); numbers of urine leaks were also estimated. Potential selection bias was countered using multivariate regression and propensity score analysis. RESULTS: Duloxetine alone, duloxetine in combination with conservative treatment, and conservative treatment alone were associated with roughly two fewer leaks per week compared with no treatment. Duloxetine alone and with conservative treatment for SUI were associated with incremental quality-adjusted life-years (QALYs) of about 0.03 over a year compared with no treatment or with conservative treatment alone. Conservative treatment alone did not show an effect on QALYs. None of the interventions appeared to have marked impacts on costs over a year. Depending on the form of matching, duloxetine either dominated or had an incremental cost-effectiveness ratio (ICER) below pound900 per QALY gained compared with no treatment and with conservative treatment alone. Duloxetine plus conservative therapy had an ICER below pound5500 compared with no treatment or conservative treatment alone. Duloxetine compared with duloxetine plus conservative therapy showed similar outcomes but an additional cost for the combined intervention. CONCLUSIONS: Although the limitations of the use of SUIT's observational data for this purpose need to be acknowledged, the study suggests that initiating duloxetine therapy in SUI is a cost-effective treatment alternative.

Patient characteristics impacting health state index scores, measured by the EQ-5D of females with stress urinary incontinence symptoms.

OBJECTIVE: To describe the characteristics of women seeking treatment for symptoms of stress urinary incontinence (SUI) and to investigate the association of SUI symptoms with generic health-related quality of life (HRQoL) as measured by the EuroQol (EQ-5D) instrument. METHODS: The Stress Urinary Incontinence Treatment (SUIT) study was a 12-month observational study in four European countries that evaluated the cost-effectiveness of duloxetine compared with other forms of nonsurgical intervention in the treatment of the symptoms of SUI. Four hundred thirty-one physicians observed women seeking treatment for their SUI, and recorded the care provided and the outcomes of that care at enrollment and at 3, 6 and 12 months afterward The impact of SUI on baseline HRQoL as expressed by the EQ-5D index score was assessed by linear and logistic regression. RESULTS: Three thousand seven hundred sixty-two women were enrolled into SUIT, with the largest patient group from Germany. Overall, the majority of women were postmenopausal, had a mean age of 58.0 years, were not current smokers, and tended to be overweight (mean body mass index [BMI]=27.7 kg/m2), with at least one comorbidity. The health state index scores were significantly and independently influenced by the presence of comorbidity(ies) affecting quality of life, total number of stress and urge incontinence episodes, urinary incontinence subtype, comorbidity(ies) affecting incontinence, BMI, socioeconomic status, educational status, age, and country. CONCLUSION: This article describes the characteristics of patients at the SUIT enrollment visit, and demonstrates that the number of incontinence episodes has a significant impact on the EQ-5D index score.

Patient reported outcomes tools in an observational study of female stress urinary incontinence.

AIMS: To determine which patient characteristics, incontinence and non-incontinence related, are associated with the symptom severity scores of the Urogenital Distress Inventory (UDI) and the International Consultation on Incontinence Questionnaire Urinary Incontinence (ICIQ-UI); and to determine the association of both patient characteristics and symptom severity scores with quality-of-life scores of the Incontinence Impact Questionnaire (IIQ) and the Incontinence-Quality of Life (I-QOL) questionnaire. METHODS: Women presenting with stress urinary incontinence (SUI) symptoms in primary and secondary care entered the Stress Urinary Incontinence Treatment Study (SUIT), an observational study evaluating the cost-effectiveness of duloxetine compared to other non-surgical treatments for SUI. At enrollment patients completed the UDI-6, the short form ICIQ-UI, the IIQ-7 and the I-QOL. Multivariate linear regressions were performed with the UDI-6, ICIQ-UI SF, IIQ-7, and I-QOL as outcomes. RESULTS: The total number of incontinence episodes is the most significant explanatory variable of the two symptom questionnaire scores, but the UDI-6 score also reflects the type of incontinence. The variability of the condition-specific quality-of-life questionnaires is primarily explained by the symptom severity questionnaire scores. Although there is a high intercorrelation, both these symptom questionnaires independently contributed significantly to the IIQ-7 and I-QOL total scores. CONCLUSIONS: The UDI-6 and ICIQ-UI SF can be regarded as scientifically sound symptom questionnaires in UI evaluation; but they have differences. Since the UDI-6 and ICIQ-UI SF independently contribute to the quality-of-life scores, this suggests that in incontinence research symptom questionnaires should not focus only on incontinence, but on a broader range of urogenital symptoms.

Switching to duloxetine in selective serotonin reuptake inhibitor non- and partial-responders: effects on painful physical symptoms of depression.

Painful physical symptoms (PPS) are common in patients with depression. Our objective was to evaluate the presence of PPS in a sample of SSRI non- or partial-responders with MDD and examine the effect of a switch to duloxetine on those PPS. Outpatients who met criteria for MDD despite having taken an SSRI antidepressant for at least 6 weeks, and who had a Hamilton depression rating scale total score of at least 15 and a clinical global impression of severity score of at least 3, were randomized to switch to duloxetine by either a direct switch or a start-taper switch method. PPS were assessed at baseline and at the study endpoint using various measures including six visual analog scales (VAS) for pain (overall pain, headache, back pain, shoulder pain, interference with daily activities, and time in pain while awake), the pain subscale of the symptom questionnaire-somatic subscale, and the bodily pain subscale of the short form-36 item health survey. Clinically significant levels of pain (mean baseline VAS scores >30 mm) were seen across all VAS pain measures prior to switching. Switch to duloxetine was associated with significant improvements on all pain measures regardless of switch method, and there was evidence for an earlier reduction in pain in the start-taper switch group. In summary, MDD patients who were non- or partial-responders to SSRI treatment were found to have clinically significant pain which improved significantly following switch to duloxetine regardless of the switch method utilized.

Quality of life outcomes among patients with depression after 6 months of starting treatment: results from FINDER.

BACKGROUND: Health-related quality of life (HRQoL) data in depression are limited. We studied the impact of antidepressant (AD) treatment on HRQoL outcomes in depressed patients and investigated factors associated with these outcomes in routine practice settings. METHODS: The Factors Influencing Depression Endpoints Research (FINDER) study was a 6-month, European, prospective, observational study, designed to estimate HRQoL in 3468 adult patients with a clinically diagnosed episode of depression at baseline and at 3 and 6-months after commencing AD treatment. HRQoL was assessed by the Medical Outcome Short-Form (36) Health Survey (SF-36) and European Quality of Life-5 Dimensions (EQ-5D). Regression analysis identified baseline and treatment variables independently and significantly associated with HRQoL outcomes. RESULTS: Most HRQoL improvement occurred within 3 months of starting treatment. Better HRQoL outcomes were strongly associated with fewer somatic symptoms at baseline, AD treatment taken and not switching within AD groups. Education and occupational status were also important. Depression variables (number of previous depressions and current episode duration) were consistently associated with worse HRQoL outcomes. Self-rated depression severity was associated with poorer outcomes on the SF-36 mental component only. LIMITATIONS: As this was an observational study, the important finding that between and within AD group switching impacted HRQoL will need to be investigated in more controlled settings. CONCLUSIONS: Receiving an AD treatment was associated with large improvements in HRQoL, but switching within AD groups was consistently associated with poorer outcomes. Somatic symptoms, including painful symptoms, are often present in depressed patients and appear to negatively impact HRQoL outcomes.

"Caseness" for depression and anxiety in a depressed outpatient population: symptomatic outcome as a function of baseline diagnostic categories.

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.

Switching to duloxetine from selective serotonin reuptake inhibitor antidepressants: a multicenter trial comparing 2 switching techniques.

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

Prescribing patterns of antidepressants in Europe: results from the Factors Influencing Depression Endpoints Research (FINDER) study.

Antidepressant prescribing patterns and factors influencing the choice of antidepressant for the treatment of depression were examined in the Factors Influencing Depression Endpoints Research (FINDER) study, a prospective, observational study in 12 European countries of 3468 adults about to start antidepressant medication for their first episode of depression or a new episode of recurrent depression. Selective serotonin reuptake inhibitors (SSRIs) were the most commonly prescribed antidepressant (63.3% patients), followed by serotonin-norepinephrine reuptake inhibitors (SNRIs, 13.6%), but there was considerable variation across countries. Notably, tricyclic and tetracyclic antidepressants (TCAs) were prescribed for 26.5% patients in Germany. The choice of the antidepressant prescribed was strongly influenced by the previous use of antidepressants, which was significantly associated with the prescription of a SSRI (OR 0.64; 95% CI 0.54, 0.76), a SNRI (OR 1.49; 95% CI 1.18, 1.88) or a combination of antidepressants (OR 2.78; 95% CI 1.96, 3.96). Physician factors (age, gender, speciality) and patient factors (severity of depression, age, education, smoking, number of current physical conditions and functional syndromes) were associated with initial antidepressant choice in some models. In conclusion, the prescribing of antidepressants varies by country, and the type of antidepressant chosen is influenced by physician- as well as patient-related factors.

Factors influencing depression endpoints research (FINDER): study design and population characteristics.

Factors influencing outcomes of depression in clinical practice, especially health-related quality of life (HRQoL), are poorly understood. The Factors Influencing Depression Endpoints Research (FINDER) study is a European prospective, observational study designed to estimate the HRQoL of adults with a clinically diagnosed depressive episode at baseline, and 3 and 6 months after commencing antidepressant medication. We report here the study design and baseline patient characteristics. HRQoL was assessed by the 36-item Short-Form Health Survey (SF-36) and European Quality of Life-5 Dimensions (EQ-5D). Patient ratings on Hospital Anxiety and Depression Scale (HADS) and pain Visual Analogue Scale (VAS) were also obtained. Results (n=3468) showed that SF-36 mental component summary (mean 22.2) was more than two SDs below general population norms (mean 50.0) and one SD below clinical depression norms (mean 34.8); the physical component summary (mean 46.1) was similar to general population (mean 50.0) and clinical depression norms (mean 45.0). Mean EQ-5D scores were also lower than general population norms. Mean HADS-Depression and -Anxiety subscores were 12.3 and 13.0, respectively. Fifty-six percent of patients reported an overall pain VAS score of at least 30mm and 70% of these patients had no physical explanation for their pain. Further investigation into factors associated with HRQoL in depression after treatment initiation is warranted.

A randomized, controlled trial of duloxetine alone vs. duloxetine plus a telephone intervention in the treatment of depression.

OBJECTIVE: We hypothesized that combining antidepressant medication with a standardized telephone adherence support intervention would lead to superior outcomes in the treatment of depression compared with antidepressant medication alone. METHOD: Patients with depression were randomized to receive the antidepressant duloxetine alone (DLX), or duloxetine plus a standardized telephone intervention (DLX+TI), for 12 weeks of open-label treatment. The primary outcome measure was remission (HAMD 17 total score 90% at every visit) in both groups. CONCLUSIONS: A telephone intervention in combination with antidepressant medication (duloxetine) did not improve depression outcomes compared with antidepressant alone in this clinical trial, perhaps due to high drug adherence in both treatment groups. Addition of a telephone intervention was, however, associated with increased reporting of AEs.

Relationship of somatic symptoms with depression severity, quality of life, and health resources utilization in patients with major depressive disorder seeking primary health care in Spain.

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.
