Remission status in persistent depressive disorder following acute treatment with psychotherapy plus medication or medication alone: A 2-year naturalistic follow-up.

OBJECTIVE: Long-term benefits of acute-phase treatments for persistent depressive disorder (PDD) are unclear. Treatment guidelines disagree on the efficacy of cognitive behavioral analysis system of psychotherapy (CBASP). We examined whether acute CBASP protected against recurrence in PDD patients over two years of naturalistic follow-up. METHODS: An observational study evaluated major depressive episode (MDE) recurrences in patients completing the Research Evaluating the Value of Augmenting Medication with Psychotherapy (REVAMP) trial. Enrollees 18-75 years had PDD: current chronic MDE, recurrent MDEs with incomplete recovery, or double depression. All received open-label antidepressant medication (ADM) for 12 weeks. Non-remitters, continuing on ADM, were randomized (2:2:1) to 12 weeks of 1) CBASP, 2) brief supportive therapy (BSP), or 3) ADM alone (MEDS). Patients completing this 12-week randomized phase were offered two-year follow-up. Blinded raters assessed the primary outcome, remission status, using the Longitudinal Interval Follow-up Evaluation and Hamilton Depression Rating Scale at 3-month intervals. Analyses evaluated group differences and non-specific predictors of remission status. RESULTS: Of 323 participants entering follow-up, 203 (62.8%) met current MDE criteria during follow-up, without between-group differences: BSP: 83 (65.3%), CBASP: 85 (60.2%), MEDS: 35 (63.6%), Chi-square = 0.75; p = 0.69. Remission after acute treatment, lack of comorbid anxiety disorder, and female gender were significantly associated with lower recurrence risk. CONCLUSION: Similar to the acute phase outcomes, no group differences emerged over the 2-year follow-up, suggesting no long-term benefit of a 12-week CBASP treatment with ADM over other PDD treatments. Findings underscore the difficulty of PDD treatment and the importance of acute treatment remission. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00057551.

Dropouts versus completers among chronically depressed outpatients.

BACKGROUND: Premature termination is common among patients treated for depression with either pharmacotherapy or psychotherapy. Yet little is known about factors associated with premature treatment termination among depressed patients. METHODS: This study examines predictors of, time to, and reasons for dropout from the 12-week acute phase treatment of nonpsychotic adult outpatients, age 18-75, with chronic major depression who were randomly assigned to nefazadone alone (MED), cognitive behavioral analysis system of psychotherapy alone (CBASP) or both treatments (COMB). RESULTS: Of 681 randomized study participants, 156 were defined as dropouts. Dropout rates were equivalent across the three treatments. Among dropouts, those in COMB remained in treatment (Mean=40 days) significantly longer than those in either MED (Mean=27 days) or CBASP (Mean=28 days). Dropouts attributed to medication side-effects were significantly lower in COMB than in MED, suggesting that the relationship with the psychotherapist may increase patient willingness to tolerate side-effects associated with antidepressant medications. Ethnic or racial minority status, younger age, lower income, and co-morbid anxiety disorders significantly predicted dropout in the full sample. Within treatments, differences between completers and dropouts in minority status and the prevalence of anxiety disorders were most pronounced in MED. Among those receiving CBASP, dropouts had significantly lower therapeutic alliance scores than completers. LIMITATIONS: The sample included only individuals with chronic depression. CONCLUSIONS: Predictors of dropout included baseline patient characteristics, but not early response to treatment. Ethnic and racial minorities and those with comorbid anxiety are at higher risk of premature termination, particularly in pharmacotherapy, and may require modified treatment strategies.

Recurrent depression: patient characteristics, clinical course, and current recommendations for management.

A significant proportion of depressed patients will experience multiple episodes of depression throughout their lifetimes, and, in recent years, attention has been paid to the identification of risk factors associated with a recurrent course of major depression. Residual depressive symptoms following acute phase therapy appears to be the most important clinical risk factor leading to recurrence. However, advances in empirically-supported treatment algorithms and guidelines, and in pharmacotherapy and psychotherapy, provide physicians with the tools necessary to improve short- and long-term outcomes in the treatment of depression. Additionally, recent developments in genetic and psychological vulnerability research have sought to further improve outcomes by identifying markers in patients who may likely experience multiple depressive episodes.

Lack of ventral striatal response to positive stimuli in depressed versus normal subjects.

OBJECTIVE: Most of the functional neuroimaging studies of depression have focused primarily on the resting state or responses to negatively valenced stimuli. However, depression consists not only of an accentuation of negative affective processing but of an inability to experience pleasure or positive motivation. The authors tested the hypothesis that depressed subjects would show less activation than healthy comparison subjects, in response to positive stimuli, in ventral striatal regions associated with processing of reward and positive stimuli. METHOD: Positive, negative, and neutral words were presented to 10 unmedicated depressed patients and 12 healthy comparison subjects in the context of a 3T functional magnetic resonance imaging (MRI) paradigm. Image processing and analysis were performed using statistical parametric mapping with a mixed-effects model. Significant differences in neural responses were assessed, examining group, condition, and interaction effects of interest within the context of a general linear model. RESULTS: Relative to comparison subjects, depressed patients demonstrated significantly less bilateral ventral striatal activation to positive stimuli, correlating with decreased interest/pleasure in and performance of activities. They also displayed decreased activation to positive stimuli in a dorsomedial frontal region associated with processing of self-related stimuli. Responses of depressed subjects to negative stimuli were consistent with the growing literature on frontolimbic dysfunction in depression. CONCLUSIONS: This finding 1) supports a pathophysiological model of depression that includes reward/motivational pathway dysfunction, 2) suggests a contributing neural substrate of the inability to experience pleasure or engage in rewarding activities, 3) provides greater specification of abnormalities of basal ganglia function in depression, and 4) may help guide treatment approaches.

A comparative trial of psychotherapy and pharmacotherapy for "pure" dysthymic patients.

BACKGROUND: Psychotherapy of "pure" dysthymic disorder remains understudied. This article reports outcomes of an acute randomized trial of 94 subjects treated for 16 weeks with either interpersonal psychotherapy (IPT), brief supportive psychotherapy (BSP), sertraline, or sertraline plus IPT. METHODS: Recruited by clinical referral and advertising, subjects met DSM-IV criteria for early onset dysthymic disorder, with no episode of major depression in the prior six months. They were randomly assigned to one of four 16-week treatments, with options for crossover or continuation treatment. Results were analyzed from the intention-to-treat sample by ANCOVA, controlling for baseline depressive severity. RESULTS: Subjects improved in all conditions over time, with the cells including sertraline pharmacotherapy showing superiority over psychotherapy alone for response and remission. Response rates were 58% for sertraline alone, 57% for combined treatment, 35% for IPT, and 31% for BSP. LIMITATIONS: The study was underpowered and may have employed too "active" a control condition. Follow-up data were unobtainable. CONCLUSIONS: In this acute trial for "pure" dysthymic disorder, sertraline with or without IPT showed advantages relative to IPT and BSP. Methodological difficulties may have limited differential outcome findings. This study bolsters a small but growing literature on the treatment of dysthymic disorder, suggesting that pharmacotherapy may acutely benefit patients more than psychotherapy.

Chronic depression: medication (nefazodone) or psychotherapy (CBASP) is effective when the other is not.

CONTEXT: Although various strategies are available to manage nonresponders to an initial treatment for depression, no controlled trials address the utility of switching from an antidepressant medication to psychotherapy or vice versa. OBJECTIVE: To compare the responses of chronically depressed nonresponders to 12 weeks of treatment with either nefazodone or cognitive behavioral analysis system of psychotherapy (CBASP) who were crossed over to the alternate treatment (nefazodone, n = 79; CBASP, n = 61). DESIGN: Crossover trial. SETTING: Twelve academic outpatient psychiatric centers. PATIENTS: There were 140 outpatients with chronic major depressive disorder; 92 (65.7%) were female, 126 (90.0%) were white, and the mean age was 43.1 years. Thirty participants dropped out of the study prematurely, 22 in the nefazodone group and 8 in the CBASP group. INTERVENTIONS: Treatment lasted 12 weeks. The dosage of nefazodone was 100 to 600 mg/d; CBASP was provided twice weekly during weeks 1 through 4 and weekly thereafter. MAIN OUTCOME MEASURES: The 24-item Hamilton Rating Scale for Depression, administered by raters blinded to treatment, the Clinician Global Impressions-Severity scale, and the 30-item Inventory for Depressive Symptomatology-Self-Report. RESULTS: Analysis of the intent-to-treat sample revealed that both the switch from nefazodone to CBASP and the switch from from CBASP to nefazodone resulted in clinically and statistically significant improvements in symptoms. Neither the rates of response nor the rates of remission were significantly different when the groups of completers were compared. However, the switch to CBASP following nefazodone therapy was associated with significantly less attrition due to adverse events, which may explain the higher intent-to-treat response rate among those crossed over to CBASP (57% vs 42%). CONCLUSIONS: Among chronically depressed individuals, CBASP appears to be efficacious for nonresponders to nefazodone, and nefazodone appears to be effective for CBASP nonresponders. A switch from an antidepressant medication to psychotherapy or vice versa appears to be useful for nonresponders to the initial treatment.

Self-reported depressive symptom measures: sensitivity to detecting change in a randomized, controlled trial of chronically depressed, nonpsychotic outpatients.

This study evaluated and compared the performance of three self-report measures: (1) 30-item Inventory of Depressive Symptomatology-Self-Report (IDS-SR30); (2) 16-item Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR16); and (3) Patient Global Impression-Improvement (PGI-I) in assessing clinical outcomes in depressed patients during a 12-week, acute phase, randomized, controlled trial comparing nefazodone, cognitive-behavioral analysis system of psychotherapy (CBASP), and the combination in the treatment of chronic depression. The IDS-SR30, QIDS-SR16, PGI-I, and the 24-item Hamilton Depression Rating Scale (HDRS24) ratings were collected at baseline and at weeks 1-4, 6, 8, 10, and 12. Response was defined a priori as a > or =50% reduction in baseline total score for the IDS-SR30 or for the QIDS-SR16 or as a PGI-I score of 1 or 2 at exit. Overall response rates (LOCF) to nefazodone were 41% (IDS-SR30), 45% (QIDS-SR16), 53% (PCI-I), and 47% (HDRS17). For CBASP, response rates were 41% (IDS-SR30), 45% (QIDS-SR16), 48% (PGI-I), and 46% (HDRS17). For the combination, response rates were 68% (IDS-SR30 and QIDS-SR16), 73% (PGI-I), and 76% (HDRS17). Similarly, remission rates were comparable for nefazodone (IDS-SR30=32%, QIDS-SR16=28%, PGI-I=22%, HDRS17=30%), for CBASP (IDS-SR30=32%, QIDS-SR16=30%, PGI-I=21%, HDRS17=32%), and for the combination (IDS-SR30=52%, QIDS-SR16=50%, PGI-I=25%, HDRS17=49%). Both the IDS-SR30 and QIDS-SR16 closely mirrored and confirmed findings based on the HDRS24. These findings raise the possibility that these two self-reports could provide cost- and time-efficient substitutes for clinician ratings in treatment trials of outpatients with nonpsychotic MDD without cognitive impairment. Global patient ratings such as the PGI-I, as opposed to specific item-based ratings, provide less valid findings.

HPA axis activation in major depression and response to fluoxetine: a pilot study.

Hypothalamic-pituitary-adrenal (HPA) axis activation is a frequently observed phenomenon in major depression. However, whether this activation has any implications for treatment is unknown. To address this question, we examined baseline response to metyrapone and 6-week response to fluoxetine. Premenopausal women (n = 20) who met criteria for major depression with no other confounding Axis I disorders, medications, or medical illnesses and were not taking hormonal contraceptives were evaluated with an evening metyrapone challenge before the onset of treatment. Twenty-one normal women were also studied with the evening metyrapone challenge. The depressed patients then entered an open label treatment with fluoxetine for 6 weeks. Subjects were classified as responders if they demonstrated a 50% or greater decrease in Hamilton Depression Rating Scale rating. As a group, the depressed women demonstrated significantly increased ACTH secretion compared to control women before the onset of treatment, during the metyrapone challenge. Before treatment, women who were non-responders to fluoxetine showed increased HPA axis activation compared to controls, while the fluoxetine responders did not differ significantly from normal subjects in their ACTH levels during metyrapone challenge. These results suggest that overactivity of the HPA axis may be one factor associated with slower response to fluoxetine. This may reflect the greater severity of subjects with HPA axis dysregulation or the need to normalize the HPA axis with medications for optimal response.

Cognitive-behavioral analysis system of psychotherapy as a maintenance treatment for chronic depression.

Although the efficacy of maintenance pharmacotherapy for the prevention of recurrence in major depressive disorder (MDD) is well documented, few studies have tested the efficacy of psychotherapy as a maintenance treatment. The authors examined the efficacy of the cognitive-behavioral analysis system of psychotherapy (CBASP) as a maintenance treatment for chronic forms of MDD. Eighty-two patients who had responded to acute and continuation phase CBASP were randomized to monthly CBASP or assessment only for 1 year. Significantly fewer patients in the CBASP than assessment only condition experienced a recurrence. The 2 conditions also differed significantly on change in depressive symptoms over time. These findings support the use of CBASP as a maintenance treatment for chronic forms of MDD.

Randomized, placebo-controlled trial of nefazodone maintenance treatment in preventing recurrence in chronic depression.

BACKGROUND: Maintenance treatment to prevent recurrences is recommended for chronic forms of major depressive disorder (MDD), but few studies have examined maintenance efficacy of antidepressants with chronic MDD. This randomized, placebo-controlled study of the efficacy and safety of nefazodone in preventing recurrence was conducted for patients with chronic MDD. METHODS: A total of 165 outpatients with chronic, nonpsychotic MDD, MDD plus dysthymic disorder ("double-depression"), or recurrent MDD with incomplete inter-episode recovery, who achieved and maintained a clinical response during acute and continuation treatment with either nefazodone alone or nefazodone combined with psychotherapy, were randomized to 52 weeks of double-blind nefazodone (maximum dose 600 mg/day) or placebo. The occurrence of major depressive episodes during maintenance treatment was assessed with the 24-item Hamilton Rating Scale for Depression, a DSM-IV MDD checklist, and a blinded review of symptom exacerbations by a consensus committee of research clinicians. RESULTS: Application of a competing-risk model that estimated the conditional probability of recurrence among those patients remaining on active therapy revealed a significant (p =.043) difference between nefazodone (n = 76) and placebo (n = 74) when the latter part of the 1-year maintenance period was emphasized. At the end of 1 year, the conditional probability of recurrence was 30.3% for nefazodone-treated patients, compared with 47.5% for placebo-treated patients. Prior concomitant psychotherapy during acute/continuation treatment, although enhancing the initial response, was not associated with lower recurrence rates. Discontinuations due to adverse events were relatively low for both nefazodone (5.3%) and placebo (4.8%). Somnolence was significantly greater among the patients taking active medication (15.4%), compared with placebo (4.6%). CONCLUSIONS: Nefazodone is well-tolerated and is an effective maintenance therapy for chronic forms of MDD.

The 16-Item Quick Inventory of Depressive Symptomatology (QIDS), clinician rating (QIDS-C), and self-report (QIDS-SR): a psychometric evaluation in patients with chronic major depression.

The 16-item Quick Inventory of Depressive Symptomatology (QIDS), a new measure of depressive symptom severity derived from the 30-item Inventory of Depressive Symptomatology (IDS), is available in both self-report (QIDS-SR(16)) and clinician-rated (QIDS-C(16)) formats. This report evaluates and compares the psychometric properties of the QIDS-SR(16) in relation to the IDS-SR(30) and the 24-item Hamilton Rating Scale for Depression (HAM-D(24)) in 596 adult outpatients treated for chronic nonpsychotic, major depressive disorder. Internal consistency was high for the QIDS-SR(16) (Cronbach's alpha =.86), the IDS-SR(30) (Cronbach's alpha =.92), and the HAM-D(24) (Cronbach's alpha =.88). QIDS-SR(16) total scores were highly correlated with IDS-SR(30) (.96) and HAM-D(24) (.86) total scores. Item-total correlations revealed that several similar items were highly correlated with both QIDS-SR(16) and IDS-SR(30) total scores. Roughly 1.3 times the QIDS-SR(16) total score is predictive of the HAM-D(17) (17-item version of the HAM-D) total score. The QIDS-SR(16) was as sensitive to symptom change as the IDS-SR(30) and HAM-D(24), indicating high concurrent validity for all three scales. The QIDS-SR(16) has highly acceptable psychometric properties, which supports the usefulness of this brief rating of depressive symptom severity in both clinical and research settings.

Pharmacotherapy for chronic depression.

This article reviews the current status of the treatment of chronic depression with antidepressant medications. Short and longer term clinical trials that have investigated the efficacy of several classes of antidepressants are summarized. The important outcomes of treatment in these studies, including response category, symptom reduction, and improved psychosocial function, are elaborated. Short-term trials seem reasonably conclusive in establishing the effectiveness of antidepressants for dysthymia and double depression, although rates of remission fall short of 50%.

Continuation treatment of chronic depression: a comparison of nefazodone, cognitive behavioral analysis system of psychotherapy, and their combination.

Little is known about the relative benefits of psychotherapy, medication, and combined treatment as continuation therapies for chronic forms of major depressive disorder (MDD) after a positive response to acute treatment. We hypothesize that combined treatment would demonstrate superior continuation phase outcomes compared to either monotherapy, as evidenced by lower relapse rates and greater rates of improvement from partial to full remission. We report 16-week continuation phase outcomes for 324 patients who had participated in either the acute phase of a randomized multicenter trial of nefazodone, Cognitive Behavioral Analysis System of Psychotherapy (CBASP), or combination therapy (COMB) for chronic forms of MDD. Patients entering the continuation phase had either fully or partially remitted after 12 weeks of acute phase treatment. The primary efficacy measure was the 24-item Hamilton Rating Scale for Depression. For patients in remission at acute phase exit, 73.3% (107/146) maintained their remitted status at endpoint of the continuation phase. Of those having a partial remission at acute phase exit, 52.9% (92/174) achieved full remission by end of continuation. A greater proportion of patients maintained a partial or full remission status on COMB (90%) compared to nefazodone (80%, p=0.011) or to CBASP (82%, p=0.042). These differences reflected greater symptom re-emergence in the partial remission groups on CBASP and nefazodone monotherapy compared to COMB. Continuation treatment assignment was not randomized or blinded. There was no placebo group. Most patients with chronic forms of MDD sustained their acute phase response and more than 50% of partial remitters achieved full remission while continuing treatment with nefazodone, CBASP, or COMB. COMB was associated with less symptom re-emergence during the continuation phase than either monotherapy, particularly for partial remitters.

Double-blind switch study of imipramine or sertraline treatment of antidepressant-resistant chronic depression.

BACKGROUND: Although various strategies have been proposed to treat antidepressant nonresponders, little controlled research has been published that examines prospectively the use of switching to an alternate antidepressant. METHODS: This was a multisite study in which outpatients with chronic major depression (with or without concurrent dysthymia), who failed to respond to 12 weeks of double-blind treatment with either sertraline hydrochloride (n = 117) or imipramine hydrochloride (n = 51), were crossed over or switched to 12 additional weeks of double-blind treatment with the alternate medication. Outcome measures included the 24-item Hamilton Rating Scale for Depression and the Clinical Global Impressions--Severity and Improvement scales. RESULTS: The switch from sertraline to imipramine (mean dosage, 221 mg/d) and from imipramine to sertraline (mean dosage, 163 mg/d) resulted in clinically and statistically significant improvements. The switch to sertraline treatment was associated with fewer adverse effect complaints and significantly less attrition owing to adverse effects. Although sertraline treatment also resulted in significantly higher response rates in the intent-to-treat samples (60% in the sertraline group and 44% in the imipramine group), neither the intent-to-treat remission rates nor the response and remission rates among study completers differed significantly. Moreover, after considering the effect of attrition, there were no significant treatment effects on the more comprehensive generalized estimating equation analyses of the continuous dependent measures. CONCLUSIONS: More than 50% of chronically depressed antidepressant nonresponders benefited from a switch from imipramine to sertraline, or vice versa, despite a high degree of chronicity. As in the initial trial, sertraline was generally better tolerated than imipramine. Switching to a standard antidepressant of a different class is a useful treatment strategy for antidepressant nonresponders and could be considered a standard of comparison for future studies of novel alternate strategies.

Psychosocial outcomes following long-term, double-blind treatment of chronic depression with sertraline vs placebo.

BACKGROUND: Chronic forms of depression are associated with significant functional and psychosocial impairments. To date, no study has measured psychosocial functioning in this population during long-term maintenance antidepressant treatment or following the double-blind discontinuation of treatment. METHODS: Patients with chronic major or double depression completed 12 weeks of short-term treatment followed by 16 weeks of continuation treatment with sertraline hydrochloride. Responders at the end of the continuation phase were randomized, double-blind, to 18 months of maintenance therapy with either sertraline (n = 77) or placebo (n = 84). Multiple domains of psychosocial functioning were assessed during double-blind therapy. RESULTS: Substantial worsening in psychosocial function measures occurred in patients taking placebo compared with sertraline during maintenance. Patients with reemergence of depression lost psychosocial gains regardless of treatment. In the subsample of patients who remained in remission throughout maintenance, most of the observed improvement in psychosocial functioning occurred during short-term treatment. By maintenance end point, normalization of functioning was achieved by 58% to 84% of remitters, depending on the outcome measure used. CONCLUSIONS: These results indicate that long-term treatment of chronic forms of depression can result in sustained psychosocial benefits. Discontinuation of treatment results in frequent reemergence of symptoms and loss of psychosocial gains. Long-term treatment resulted in only modest further improvement of psychosocial measures over that achieved in the short-term phase.
