Omega-3 fatty acids in bipolar disorder: clinical and research considerations.

Several lines of evidence suggest that omega-3 fatty acids may be important in the pathophysiology, treatment or prevention of bipolar disorder (BD). Electronic and manual searches were conducted in order to review the literature relevant to the etiology and treatment of BDs with omega-3 fatty acids. We also present data from a randomized, double-blind, placebo-controlled pilot study conducted at three sites (N = 10) comparing an omega-3 fatty acid (docosahexaenoic acid, DHA) versus placebo, added to psychosocial treatment for women with BD who chose to discontinue standard pharmacologic treatment while attempting to conceive. While some epidemiologic and preclinical data support the role of omega-3 fatty acids in BD, clinical trials to date have yielded conflicting results. In our pilot study of 10 Caucasian women taking DHA while attempting to conceive (BP1 = 9, BPII = 1), age 27-42 years, DHA was well tolerated and suggests that a larger study would be feasible. The elucidation of the potential role of omega-3 fatty acids as a treatment for BD requires further study. The current data are not sufficient to support a recommendation of monotherapy treatment as a substitute for standard pharmacologic treatments. However, judicious monotherapy in selected clinical situations, or adjunctive use, may be warranted pending further data from adequately powered controlled clinical trials. Our pilot trial of DHA in women who plan to stop conventional psychotropics in order to conceive suggests that such trials are feasible.

Clinical differences among depressed patients with and without a history of suicide attempts: findings from the STAR*D trial.

BACKGROUND: This study sought to determine whether a history of suicide attempts among outpatients diagnosed with nonpsychotic major depressive disorder (MDD) is correlated with any difference in clinical presentation that should influence patient care. METHODS: Baseline data from the Sequenced Treatment Alternatives to Relieve Depression (STAR()D) trial on outpatients with MDD treated in primary and specialty care settings were used to model significant demographic and clinical correlates of suicide attempter status. RESULTS: Altogether, 16.5% of participants (n=667) reported prior suicide attempts. Controlling for age, gender, and depressive symptom severity, previous attempters had more current general medical conditions (micro=3.2 vs. 2.9, p<.0001), more current alcohol/substance abuse (p<.0001), and more work hours missed in the past week (26.2% vs. 18.2%, p<.0001) than non-attempters. On average, for the previously suicidal, the onset of MDD occurred 8.9 years earlier in life (p<.0001) and had included 1.2 additional depressive episodes (p=0.001) compared to those without prior suicidal behavior. Previous attempters also reported more current suicidal ideation (61.3% of previous attempters, adjusted OR 1.6, vs. 45.5% of nonattempters, p<.0001). LIMITATIONS: Presence or absence of a history of suicide attempts was determined only through self report. CONCLUSIONS: Those with a history of suicidal behavior suffer a greater burden of depressive illness. Earlier intervention and ongoing, aggressive care, including maintenance-phase pharmacotherapy, may be critical to mitigating the long-term consequences associated with this increased disease burden.

Towards a noninvasive method for determination of patient-specific wall strength distribution in abdominal aortic aneurysms.

The spatial distributions of both wall stress and wall strength are required to accurately evaluate the rupture potential for an individual abdominal aortic aneurysm (AAA). The purpose of this study was to develop a statistical model to non-invasively estimate the distribution of AAA wall strength. Seven parameters--namely age, gender, family history of AAA, smoking status, AAA size, local diameter, and local intraluminal thrombus (ILT) thickness--were either directly measured or recorded from the patients hospital chart. Wall strength values corresponding to these predictor variables were calculated from the tensile testing of surgically procured AAA wall specimens. Backwards-stepwise regression techniques were used to identify and eliminate insignificant predictors for wall strength. Linear mixed-effects modeling was used to derive a final statistical model for AAA wall strength, from which 95% confidence intervals on the model parameters were formed. The final statistical model for AAA wall strength consisted of the following variables: sex, family history, ILT thickness, and normalized transverse diameter. Demonstrative application of the model revealed a unique, complex wall strength distribution, with strength values ranging from 56 N/cm2 to 133 N/cm2. A four-parameter statistical model for the noninvasive estimation of patient-specific AAA wall strength distribution has been successfully developed. The currently developed model represents a first attempt towards the noninvasive assessment of AAA wall strength. Coupling this model with our stress analysis technique may provide a more accurate means to estimate patient-specific rupture potential of AAA.

Family history of mood disorder and characteristics of major depressive disorder: a STAR*D (sequenced treatment alternatives to relieve depression) study.

INTRODUCTION: Clinicians routinely ask patients with major depressive disorder (MDD) about their family history. It is unknown, however, if patients who report a positive family history differ from those who do not. This study compared the demographic and clinical features of a large cohort of treatment-seeking outpatients with non-psychotic MDD who reported that they did or did not have at least one first-degree relative who had either MDD or bipolar disorder. METHODS: Subjects were recruited for the STAR( *)D multicenter trial. Differences in demographic and clinical features for patients with and without a family history of mood disorders were assessed after correcting for age, sex, race, and ethnicity. RESULTS: Patients with a family history of mood disorder (n=2265; 56.5%) were more frequently women and had an earlier age of onset of depression, as compared to those without such a history (n=1740; 43.5%). No meaningful differences were found in depressive symptoms, severity, recurrence, depressive subtype, or daily function. CONCLUSIONS: Women were twice as likely as men to report a positive family history of mood disorder, and a positive family history was associated with younger age of onset of MDD in the proband. Consistent with prior research, early age of onset appears to define a familial and, by extension, genetic subtype of major depressive disorder.

Prevention of missing data in clinical research studies.

Missing data is a problem that is ubiquitous to all clinical studies and a source of multiple problems from an analytic point of view (reduced statistical power, increased the type I error, bias) Statistical approaches have been developed to analyze data collected from trials with missing data. Understanding and implementing the appropriate statistical technique is essential but should be differentiated from preventive approaches that are designed to reduce rates of missing data In this article, we draw attention to these preventive efforts. Seven steps to minimizing the amount of missing data are defined as documentation, training, monitoring reports, patient contact, data entry and management, pilot studies, and communication. Although the implementation of these approaches is time consuming and costly, the overall quality of the study is increased. Despite efforts devoted to areas, no study is without missing data. Once the study is completed, it is essential to assess the pattern of missing data and apply the appropriate statistical analysis.

Bupropion-SR, sertraline, or venlafaxine-XR after failure of SSRIs for depression.

BACKGROUND: After unsuccessful treatment for depression with a selective serotonin-reuptake inhibitor (SSRI), it is not known whether switching to one antidepressant is more effective than switching to another. METHODS: We randomly assigned 727 adult outpatients with a nonpsychotic major depressive disorder who had no remission of symptoms or could not tolerate the SSRI citalopram to receive one of the following drugs for up to 14 weeks: sustained-release bupropion (239 patients) at a maximal daily dose of 400 mg, sertraline (238 patients) at a maximal daily dose of 200 mg, or extended-release venlafaxine (250 patients) at a maximal daily dose of 375 mg. The study was conducted in 18 primary and 23 psychiatric care settings. The primary outcome was symptom remission, defined by a total score of 7 or less on the 17-item Hamilton Rating Scale for Depression (HRSD-17) at the end of the study. Scores on the Quick Inventory of Depressive Symptomatology - Self Report (QIDS-SR-16), obtained at treatment visits, determined secondary outcomes, including remission (a score of 5 or less at exit) and response (a reduction of 50 percent or more on baseline scores). RESULTS: Remission rates as assessed by the HRSD-17 and the QIDS-SR-16, respectively, were 21.3 percent and 25.5 percent for sustained-release bupropion, 17.6 percent and 26.6 percent for sertraline, and 24.8 percent and 25.0 percent for extended-release venlafaxine. QIDS-SR-16 response rates were 26.1 percent for sustained-release bupropion, 26.7 percent for sertraline, and 28.2 percent for extended-release venlafaxine. These treatments did not differ significantly with respect to outcomes, tolerability, or adverse events. CONCLUSIONS: After unsuccessful treatment with an SSRI, approximately one in four patients had a remission of symptoms after switching to another antidepressant. Any one of the medications in the study provided a reasonable second-step choice for patients with depression. (ClinicalTrials.gov number, NCT00021528.).

Medication augmentation after the failure of SSRIs for depression.

BACKGROUND: Although clinicians frequently add a second medication to an initial, ineffective antidepressant drug, no randomized controlled trial has compared the efficacy of this approach. METHODS: We randomly assigned 565 adult outpatients who had nonpsychotic major depressive disorder without remission despite a mean of 11.9 weeks of citalopram therapy (mean final dose, 55 mg per day) to receive sustained-release bupropion (at a dose of up to 400 mg per day) as augmentation and 286 to receive buspirone (at a dose of up to 60 mg per day) as augmentation. The primary outcome of remission of symptoms was defined as a score of 7 or less on the 17-item Hamilton Rating Scale for Depression (HRSD-17) at the end of this study; scores were obtained over the telephone by raters blinded to treatment assignment. The 16-item Quick Inventory of Depressive Symptomatology--Self-Report (QIDS-SR-16) was used to determine the secondary outcomes of remission (defined as a score of less than 6 at the end of this study) and response (a reduction in baseline scores of 50 percent or more). RESULTS: The sustained-release bupropion group and the buspirone group had similar rates of HRSD-17 remission (29.7 percent and 30.1 percent, respectively), QIDS-SR-16 remission (39.0 percent and 32.9 percent), and QIDS-SR-16 response (31.8 percent and 26.9 percent). Sustained-release bupropion, however, was associated with a greater reduction (from baseline to the end of this study) in QIDS-SR-16 scores than was buspirone (25.3 percent vs. 17.1 percent, P<0.04), a lower QIDS-SR-16 score at the end of this study (8.0 vs. 9.1, P<0.02), and a lower dropout rate due to intolerance (12.5 percent vs. 20.6 percent, P<0.009). CONCLUSIONS: Augmentation of citalopram with either sustained-release bupropion or buspirone appears to be useful in actual clinical settings. Augmentation with sustained-release bupropion does have certain advantages, including a greater reduction in the number and severity of symptoms and fewer side effects and adverse events.

Remissions in maternal depression and child psychopathology: a STAR*D-child report.

CONTEXT: Children of depressed parents have high rates of anxiety, disruptive, and depressive disorders that begin early, often continue into adulthood, and are impairing. OBJECTIVE: To determine whether effective treatment with medication of women with major depression is associated with reduction of symptoms and diagnoses in their children. DESIGN: Assessments of children whose depressed mothers were being treated with medication as part of the multicenter Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial conducted (between December 16, 2001 and April 24, 2004) in broadly representative primary and psychiatric outpatient practices. Children were assessed by a team of evaluators not involved in maternal treatment and unaware of maternal outcomes. Study is ongoing with cases followed at 3-month intervals. SETTING AND PATIENTS: One hundred fifty-one mother-child pairs in 8 primary care and 11 psychiatric outpatient clinics across 7 regional centers in the United States. Children were aged 7 to 17 years. MAIN OUTCOME MEASURES: Child diagnoses based on the Kiddie Schedule for Affective Disorders and Schizophrenia; child symptoms based on the Child Behavior Checklist; child functioning based on the Child Global Assessment Scale in mothers whose depression with treatment remitted with a score of 7 or lower or whose depression did not remit with a score higher than 7 on the Hamilton Rating Scale for Depression. RESULTS: Remission of maternal depression after 3 months of medication treatment was significantly associated with reductions in the children's diagnoses and symptoms. There was an overall 11% decrease in rates of diagnoses in children of mothers whose depression remitted compared with an approximate 8% increase in rates of diagnoses in children of mothers whose depression did not. This rate difference remained statistically significant after controlling for the child's age and sex, and possible confounding factors (P = .01). Of the children with a diagnosis at baseline, remission was reported in 33% of those whose mothers' depression remitted compared with only a 12% remission rate among children of mothers whose depression did not remit. All children of mothers whose depression remitted after treatment and who themselves had no baseline diagnosis for depression remained free of psychiatric diagnoses at 3 months, whereas 17% of the children whose mothers remained depressed acquired a diagnosis. Findings were similar using child symptoms as an outcome. Greater level of maternal response was associated with fewer current diagnoses and symptoms in the children, and a maternal response of at least 50% was required to detect an improvement in the child. CONCLUSIONS: Remission of maternal depression has a positive effect on both mothers and their children, whereas mothers who remain depressed may increase the rates of their children's disorders. These findings support the importance of vigorous treatment for depressed mothers in primary care or psychiatric clinics and suggest the utility of evaluating the children, especially children whose mothers continue to be depressed.

Variation in the gene encoding the serotonin 2A receptor is associated with outcome of antidepressant treatment.

Depressive disorders account for a large and increasing global burden of disease. Although the condition of many patients improves with medication, only a minority experience full remission, and patients whose condition responds to one medication may not have a response to others. Individual variation in antidepressant treatment outcome is, at present, unpredictable but may have a partial genetic basis. We searched for genetic predictors of treatment outcome in 1,953 patients with major depressive disorder who were treated with the antidepressant citalopram in the Sequenced Treatment Alternatives for Depression (STAR*D) study and were prospectively assessed. In a split-sample design, a selection of 68 candidate genes was genotyped, with 768 single-nucleotide-polymorphism markers chosen to detect common genetic variation. We detected significant and reproducible association between treatment outcome and a marker in HTR2A (P range 1 x 10(-6) to 3.7 x 10(-5) in the total sample). Other markers in HTR2A also showed evidence of association with treatment outcome in the total sample. HTR2A encodes the serotonin 2A receptor, which is downregulated by citalopram. Participants who were homozygous for the A allele had an 18% reduction in absolute risk of having no response to treatment, compared with those homozygous for the other allele. The A allele was over six times more frequent in white than in black participants, and treatment was less effective among black participants. The A allele may contribute to racial differences in outcomes of antidepressant treatment. Taken together with prior neurobiological findings, these new genetic data make a compelling case for a key role of HTR2A in the mechanism of antidepressant action.

Enrolling research subjects from clinical practice: ethical and procedural issues in the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial.

The Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial is a multi-site effectiveness study funded by the National Institute of Mental Health (NIMH) with the aim of identifying successful, acceptable and cost-effective treatment strategies for outpatients with unremitted depression. With enrollment of 4,041 adults with major depressive disorder (MDD), it is the largest controlled psychiatric treatment study ever undertaken. In the course of developing procedures to ensure that ambitious enrollment goals were met, a number of ethical and practical issues became apparent that underscore the conflicts between effectiveness research and human subject protections. These are delineated as they relate to study design; eligibility criteria; incentives to subjects; investigators and clinical sites; the complementary roles of clinical research coordinators (CRCs) and study clinicians; and recruitment and consent procedures. The STAR*D trial exemplifies the interplay and tension between those strategies that integrate research and clinical aims and roles in the service of enhancing external validity, site participation, and recruitment and retention versus those strategies that differentiate research and clinical treatment in the service of research integrity and human subject protections. We hope that a discussion of these key challenges and dilemmas and how they have been addressed will help inform future discussions concerning design and conduct of ethical effectiveness trials designed to optimize care in real world clinical settings.

Positron emission tomography imaging of peripheral benzodiazepine receptor binding in human immunodeficiency virus-infected subjects with and without cognitive impairment.

The pathology associated with late-stage dementia in human immunodeficiency virus (HIV) infection has been studied extensively. Neuropathological examination has demonstrated abundant activation and infection of macrophages/microglia termed HIV encephalitis. For obvious reasons, less is known regarding the neuropathology of minor cognitive impairment seen in earlier stages of HIV infection. The authors examined the utility of the peripheral benzodiazepine receptor ligand PK11195 in positron emission tomography (PET) imaging to assess microglial/macrophage activation in the brains of HIV-infected subjects with minor neurocognitive impairment in a cross-sectional study of 12 HIV infected individuals and 5 age-matched noninfected controls. Subjects were given a battery of neuropsychological tests in addition to assessing CD4 T-cell count and peripheral viremia followed by contrast enhanced magnetic resonance imaging (MRI) and PET with [15O]H2O followed by [11C](R)-PK11195. Two of the six neurocognitively impaired HIV-infected subjects demonstrated plasma viral breakthrough, whereas only one of six nonimpaired individuals demonstrated plasma viral load near the limits of detection. MRI demonstrated no abnormal enhancement and although atrophy was more prominent in impaired subjects, it was also present though to a lesser extent in nonimpaired subjects. None of the 12 HIV-infected subjects demonstrated increased retention of [11C](R)-PK11195 in the brain parenchyma compared to the 5 controls. These results suggest that either [11C](R)-PK11195 PET assessment is insensitive to the degree of macrophage activation in HIV-associated minor neurocognitive impairment or macrophage activation is not the pathological substrate of this neurological condition.

Self-rated global measure of the frequency, intensity, and burden of side effects.

No standard side-effect measure currently available can be easily used in clinical practice for patients receiving treatment for depression. The Frequency, Intensity, and Burden of Side Effects Rating (FIBSER) Scale was developed to document these three domains of side effects in patients treated in the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) project. This article presents data on the reliability and validity of the FIBSER. The STAR*D prospectively enrolled 4,041 outpatients with nonpsychotic major depressive disorder (MDD) who were seeking medical care (as opposed to symptomatic volunteers recruited via advertisements). The patients were treated with citalopram. Clinical assessments, including the FIBSER, were completed at 2, 4, 6, 9, 12, and, if necessary, 14 weeks after enrollment. The FIBSER was shown to be reliable, with high correlations between observations taken a short time apart, and correlations decreasing as time between observations increased. There were also consistent relationships between items over time. The FIBSER has both face and construct validity. Thus, the FIBSER is a reliable and valid self-report measure of side effects in a population receiving treatment for depression. Although it does not measure the impact of specific side effects, it does measure three domains of impact: frequency, intensity, and burden of the side effects. Its brevity makes it a useful tool for routine clinical practice. These advantages are not available in other side-effect measures.

Prospective predictors of suicide and suicide attempts in 1,556 patients with bipolar disorders followed for up to 2 years.

OBJECTIVES: Bipolar disorders are associated with high rates of suicide attempts (SAs) and completions. Several factors have been reported to be associated with suicide in persons with bipolar disorder, but most studies to date have been retrospective and have not utilized multivariate statistics to account for the redundant prediction among variables submitted for analysis. METHODS: This study examined the association between baseline clinical and demographic variables and subsequent SAs and completions through 2 years of follow-up of participants in the Systematic Treatment Enhancement Program for Bipolar Disorder using a pattern-mixture model. RESULTS: Of the sample with complete data (n = 1,556), 57 patients (3.66%) experienced an SA or completion (CS). Several variables predicted suicidality (SA + CS) in this data set when considered alone, but after controlling for redundant prediction from other baseline characteristics, only history of suicide [odds ratio (OR) = 4.52, p < 0.0001] and percent days depressed in the past year (OR = 1.16, p = 0.036) were significantly associated with SAs and completions. A secondary analysis included a greater number of variables but a smaller sample size (n = 1,014). In the secondary analyses, only prior SAs predicted prospective suicidality (OR = 3.87, p = 0.0029). CONCLUSIONS: These results indicate that patients with bipolar disorder who present with a history of SAs are over four times as likely to have a subsequent SA or completion. Further studies are needed to evaluate and prevent future attempts in this high-risk cohort.

Mitochondrial heat shock protein 60 is increased in cerebrospinal fluid following pediatric traumatic brain injury.

Mitochondrial dysfunction occurs after traumatic brain injury (TBI) and contributes significantly to subsequent cell death. Heat shock protein 60 (hsp60) is a predominantly mitochondrial protein with important homeostatic functions. Induction of hsp60 has been demonstrated in cerebral ischemia models, possibly reflecting mitochondrial stress. We measured hsp60 concentration in the cerebrospinal fluid (CSF) of 34 infants and children after severe TBI and of 7 control patients by ELISA. Peak CSF hsp60 concentration was increased in TBI patients versus controls (0.84 ng/ml, range 0-44.59, vs. 0.0 ng/ml, range 0-0.48; p<0.05). Induction of hsp60 occurred early after the injury. Peak hsp60 concentration was independently associated with the severity of injury, defined as the admission Glasgow Coma Scale score. These data suggest that increased hsp60 in CSF might reflect the severity of early mitochondrial stress or damage after TBI.

Acute and longer-term outcomes in depressed outpatients requiring one or several treatment steps: a STAR*D report.

OBJECTIVE: This report describes the participants and compares the acute and longer-term treatment outcomes associated with each of four successive steps in the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial. METHOD: A broadly representative adult outpatient sample with nonpsychotic major depressive disorder received one (N=3,671) to four (N=123) successive acute treatment steps. Those not achieving remission with or unable to tolerate a treatment step were encouraged to move to the next step. Those with an acceptable benefit, preferably symptom remission, from any particular step could enter a 12-month naturalistic follow-up phase. A score of or=11 (HRSD(17)>or=14) defined relapse. RESULTS: The QIDS-SR(16) remission rates were 36.8%, 30.6%, 13.7%, and 13.0% for the first, second, third, and fourth acute treatment steps, respectively. The overall cumulative remission rate was 67%. Overall, those who required more treatment steps had higher relapse rates during the naturalistic follow-up phase. In addition, lower relapse rates were found among participants who were in remission at follow-up entry than for those who were not after the first three treatment steps. CONCLUSIONS: When more treatment steps are required, lower acute remission rates (especially in the third and fourth treatment steps) and higher relapse rates during the follow-up phase are to be expected. Studies to identify the best multistep treatment sequences for individual patients and the development of more broadly effective treatments are needed.

A comparison of mirtazapine and nortriptyline following two consecutive failed medication treatments for depressed outpatients: a STAR*D report.

OBJECTIVE: Few controlled studies have addressed the issue of which antidepressant medications should be recommended for outpatients who have not responded to multiple treatment trials. This study compared the efficacy of switching to mirtazapine to that of switching to a tricyclic antidepressant (nortriptyline) following two prospective, consecutive, unsuccessful medication treatments for nonpsychotic major depressive disorder. METHOD: Following lack of remission or an inability to tolerate an initial trial of citalopram for up to 12 weeks (first step) and a second trial with either monotherapy involving another antidepressant or augmentation of citalopram with bupropion or buspirone (second step), adult outpatients (N=235) with nonpsychotic major depressive disorder were randomly assigned to 14 weeks of treatment with mirtazapine (up to 60 mg/day) (N=114) or nortriptyline (up to 200 mg/day) (N=121). The primary outcome, symptom remission, was defined a priori as a total exit score of </=7 on the 17-item Hamilton Rating Scale for Depression. The 16-item Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR(16)), obtained at treatment visits, provided secondary outcomes of remission (score </=5 at exit) and response (>/=50% reduction in score from baseline). RESULTS: For mirtazapine, remission rates were 12.3% and 8.0% per the Hamilton and QIDS-SR(16) scores, respectively. For nortriptyline, remission rates were 19.8% and 12.4%, respectively. QIDS-SR(16) response rates were 13.4% for mirtazapine and 16.5% for nortriptyline. Neither response nor remission rates statistically differed by treatment, nor did these two treatments differ in tolerability or adverse events. CONCLUSIONS: Switching to a third antidepressant monotherapy regimen after two consecutive unsuccessful antidepressant trials resulted in low remission rates (<20%) among patients with major depressive disorder.

A comparison of lithium and T(3) augmentation following two failed medication treatments for depression: a STAR*D report.

OBJECTIVE: More than 40% of patients with major depressive disorder do not achieve remission even after two optimally delivered trials of antidepressant medications. This study compared the effectiveness of lithium versus triiodothyronine (T(3)) augmentation as a third-step treatment for patients with major depressive disorder. METHOD: A total of 142 adult outpatients with nonpsychotic major depressive disorder who had not achieved remission or who were intolerant to an initial prospective treatment with citalopram and a second switch or augmentation trial were randomly assigned to augmentation with lithium (up to 900 mg/day; N=69) or with T(3) (up to 50 mug/day; N=73) for up to 14 weeks. The primary outcome measure was whether participants achieved remission, which was defined as a score < or =7 on the 17-item Hamilton Depression Rating Scale. RESULTS: After a mean of 9.6 weeks (SD=5.2) of treatment, remission rates were 15.9% with lithium augmentation and 24.7% with T(3) augmentation, although the difference between treatments was not statistically significant. Lithium was more frequently associated with side effects (p=0.045), and more participants in the lithium group left treatment because of side effects (23.2% versus 9.6%; p=0.027). CONCLUSIONS: Remission rates with lithium and T(3) augmentation for participants who experienced unsatisfactory results with two prior medication treatments were modest and did not differ significantly. The lower side effect burden and ease of use of T(3) augmentation suggest that it has slight advantages over lithium augmentation for depressed patients who have experienced several failed medication trials.

Tranylcypromine versus venlafaxine plus mirtazapine following three failed antidepressant medication trials for depression: a STAR*D report.

OBJECTIVE: The purpose of this study was to compare the effectiveness and tolerability of tranylcypromine and combination treatment with extended-release venlafaxine and mirtazapine in patients with treatment-resistant major depression whose current depressive episode had not responded adequately to treatment in three prior prospective medication trials. METHOD: Adult outpatients with nonpsychotic major depressive disorder who had not achieved remission or had withdrawn from treatment because of intolerance in three previous prospective medication trials were randomly assigned to receive open-label treatment with either tranylcypromine (N=58) or extended-release venlafaxine plus mirtazapine (N=51). The primary outcome measure was whether patients achieved remission, which was defined as a score < or =7 at exit on the 17-item Hamilton Depression Rating Scale (HAM-D). The HAM-D was administered by telephone by raters to whom treatment was masked. RESULTS: Remission rates were not significantly different between the two treatment groups (6.9% for the tranylcypromine group and 13.7% for the venlafaxine plus mirtazapine group). The mean daily dose at exit for tranylcypromine was 36.9 mg (SD=18.5); for venlafaxine, 210.3 mg (SD=95.2); and for mirtazapine, 35.7 mg (SD=17.6). Tranylcypromine was associated with significantly less symptom reduction and greater attrition due to intolerance. CONCLUSIONS: Remission rates were modest for both the tranylcypromine group and the extended-release venlafaxine plus mirtazapine group, and the rates were not statistically different between groups. The lower side effect burden, lack of dietary restrictions, and ease of use of venlafaxine and mirtazapine suggest that this combination may be preferred over tranylcypromine for patients with highly treatment-resistant depression who have not benefited adequately from several prior treatments.
