Background: The purpose of this study was to examine whether treatment response to fluoxetine by depressed outpatients was predicted by early improvement on any of 3 subscales (Anxiety, Depression, and Anger/Hostility) of the Symptom Questionnaire (SQ)., Methods: We evaluated 169 depressed outpatients (52.6% female) between ages 18 and 65 (mean age, 40.3 +/- 10.6 years) meeting DSM-IIIR criteria for major depressive disorder (MDD). All patients completed the SQ at baseline (week 0) and at weeks 2, 4, and 8 of treatment with fluoxetine 20 mg/d. We defined treatment response as a > or= 50% reduction in score on the 17-item Hamilton Rating Scale for Depression, and early improvement on 3 SQ subscales (Anxiety, Depression, and Anger/Hostility) as a >30% reduction in score by week 2., Results: The percentage of patients with significant early improvement in anger was significantly greater than the percentage of those with early improvements in anxiety or depression. When early improvement on the Anxiety, Depression, and Anger/Hostility subscales of the SQ were assessed independently by logistic regression, all 3 subscales were predictors of response to treatment., Conclusions: Early improvement in anger, anxiety, and depressive symptoms may predict response to antidepressant treatment among outpatients with MDD.

We sought to determine whether maca, a Peruvian plant, is effective for selective-serotonin reuptake inhibitor (SSRI)-induced sexual dysfunction. We conducted a double-blind, randomized, parallel group dose-finding pilot study comparing a low-dose (1.5 g/day) to a high-dose (3.0 g/day) maca regimen in 20 remitted depressed outpatients (mean age 36+/-13 years; 17 women) with SSRI-induced sexual dysfunction. The Arizona Sexual Experience Scale (ASEX) and the Massachusetts General Hospital Sexual Function Questionnaire (MGH-SFQ) were used to measure sexual dysfunction. Ten subjects completed the study, and 16 subjects (9 on 3.0 g/day; 7 on 1.5 g/day) were eligible for intent-to-treat (ITT) analyses on the basis of having had at least one postbaseline visit. ITT subjects on 3.0 g/day maca had a significant improvement in ASEX (from 22.8+/-3.8 to 16.9+/-6.2; z=-2.20, P=0.028) and in MGH-SFQ scores (from 24.1+/-1.9 to 17.0+/-5.7; z=-2.39, P=0.017), but subjects on 1.5 g/day maca did not. Libido improved significantly (P<0.05) for the ITT and completer groups based on ASEX item #1, but not by dosing groups. Maca was well tolerated. Maca root may alleviate SSRI-induced sexual dysfunction, and there may be a dose-related effect. Maca may also have a beneficial effect on libido.

The authors examined the impact of comorbid medical illness on the rate of relapse of major depressive disorder during continuation therapy. Subjects (N = 128) with major depressive disorder (according to DSM-III-R criteria) achieved clinical remission (a 17-item Hamilton Depression Rating Scale score < or = 7) after 8 weeks of treatment with fluoxetine and entered the continuation phase of antidepressant treatment. They used the Cumulative Illness Rating Scale to measure the severity of comorbid medical illness. Eight patients (6.3%) relapsed during the 28-week continuation phase. With logistic regression, the total burden and the severity of comorbid medical illness significantly predicted the relapse of major depressive disorder during continuation therapy with fluoxetine. Greater medical comorbidity was also associated with higher increases in self-reported symptoms of depression, anxiety, and anger during the follow-up.

An epidemiological study in Los Angeles showed that Chinese Americans had lower rates of depression compared to the U.S. national estimates. This study surveys the prevalence of major depressive disorder (MDD) among Asian-Americans in the primary care setting. A two-phase epidemiological survey was performed in the primary care clinic of a community health center in Boston, MA, which provides treatment to under-served Asian-Americans. Participants were Chinese Americans in the waiting area of the primary care clinic, 18 years of age or older, who spoke any one the four commonly used Chinese dialects. The Chinese version of the Beck Depression Inventory (CBDI) was used for initial screening. All consenting patients who screened positive (CBDI >/= 16) and a fraction of those who screened negative (CBDI < 16) were interviewed by a bilingual and bicultural psychiatrist with the Structured Clinical Interview for DSM-III-R, patient version, for confirmation of the diagnosis of MDD. There were 815 in the primary care clinic that were approached, of which 503 patients (62% female, mean age 50 +/- 17 years) filled out the CBDI in the initial phase of depression screening. Extrapolating the results from the SCID-P interviews, the prevalence of MDD among Asian-Americans in the primary care setting was estimated to be 19.6% +/- 0.06. MDD is common among Asian-Americans in primary care settings. The prevalence of MDD is comparable to or higher than those found in the U.S. nonminority populations.

Cerebrovascular diseases constitute a leading health hazard. The association between stroke and depression has been recognized for many years. Depression is the most common psychiatric disorder associated with cerebrovascular diseases, most episodes of post-stroke depression occur in the first 2 years after a cerebrovascular accident. Studies have found an association between lesion location, physical impairment, cognitive impairment, aphasia, and post-stroke depression. The location of the lesion in terms of proximity to the left frontal pole of the brain has a profound impact on the frequency and severity of post-stroke depression. Treatment modalities include pharmacotherapy, psychotherapy, electroconvulsive therapy, and rehabilitation. Understanding the psychologic and physical morbidity of post-stroke depression, as well as its timely, comprehensive treatment, are important for effective management.

The frequent comorbidity of anxiety disorders and mood disorders has been documented in previous studies. However, it remains unclear whether specific anxiety traits or disorders are more closely associated with unipolar major depression (MDD) or bipolar disorder (BPD). We sought to examine whether MDD and BPD can be distinguished by their association with specific types of anxiety comorbidity. Individuals with a primary lifetime diagnosis of either bipolar disorder (N=122) or major depressive disorder (N=114) received diagnostic assessments of anxiety disorder comorbidity, and completed questionnaires assessing anxiety sensitivity and neuroticism. The differential association of these anxiety phenotypes with MDD versus BPD was examined with multivariate modeling. Panic disorder and generalized anxiety disorder (GAD) specifically emerged amongst all the anxiety disorders as significantly more common in patients with BPD than MDD. After controlling for current mood state, anxiety sensitivity and neuroticism did not differ by mood disorder type. This study supports prior research suggesting a specific panic disorder-bipolar disorder connection, and suggests GAD may also be differentially associated with BPD. Further research is needed to clarify the etiologic basis of anxiety disorder/BPD comorbidity and to optimize treatment strategies for patients with these co-occurring disorders.

In the outpatient psychiatric care setting, patients with major depression and anxiety comply poorly with traditional tricyclic antidepressants and specific serotonin re-uptake inhibitor treatment. The purpose of this study was to examine whether the low drop out rate reported with tianeptine in randomised studies is also reflected in daily outpatient psychiatric practice. In a six-week prospective multicentre study, treatment with tianeptine (12.5mg thrice daily) in 314 patients with major depression and anxiety, drawn from 25 randomly selected outpatient psychiatric practices across India was assessed. Outcome measures were frequency of drop outs due to side-effects and change in depression and anxiety rating scale scores. Intention to treat analysis showed that 7 patients (2.3%) discontinued treatment due to side-effects. Patients with an improvement of at least 50% from baseline on Montgomery Asberg Depression Rating Scale (MADRS) increased from 18.5% at week 3 to 53.0% at week 6; on the Hamilton Anxiety Rating Scale (HARS), patient responders likewise increased from 22.6% at three weeks to 52.2% at six weeks. When used in the setting of day to day outpatient psychiatric practice, tianeptine is a well-tolerated and effective antidepressant. It could serve as a useful alternative, and improve the present low compliance with treatment in patients with major depression and anxiety.

In a previous study, of 41 depressed patients who had not responded to fluoxetine 20 mg/day, 53% were treated with high-dose fluoxetine (40-60 mg/ day) and responded (i.e., their 17-item Hamilton Rating Scale for Depression [HAM-D-17] score was <7) versus 29% and 25% of patients treated with fluoxetine plus lithium (300-600 mg/day) or fluoxetine plus desipramine (25-50 mg/day), respectively. We wanted to assess whether these findings could be replicated in a larger sample of depressed outpatients. We identified 101 outpatients with major depressive disorder (52 men and 49 women; mean age, 41.6 + 10.6 years) who were either partial responders (n = 49) or nonresponders (n = 52) to 8 weeks of treatment with fluoxetine 20 mg/ day. These patients were randomized to 4 weeks of double-blind treatment with high-dose fluoxetine (40-60 mg/day), fluoxetine plus lithium (300-600 mg/day), or fluoxetine plus desipramine (25-50 mg/day). In the overall group of patients (N = 101), there was no significant difference in response rates across the three treatment groups (high-dose fluoxetine, 42.4%; fluoxetine plus desipramine, 29.4%; fluoxetine plus lithium, 23.5%). Dropout rates were also comparable, ranging from 9.1% (high-dose fluoxetine) to 14.7% (fluoxetine plus desipramine and fluoxetine plus lithium). There were also no significant differences in response rates across the three treatment groups among partial responders (high-dose fluoxetine, 50.0%; fluoxetine plus desipramine, 33.3%; fluoxetine plus lithium, 33.3%) and nonresponders (high-dose fluoxetine, 35.3%; fluoxetine plus desipramine, 26.3%; fluoxetine plus lithium, 12.5%). At the end of the study, the mean lithium level was 0.37 + 0.15 mEq/L (n = 27; range, 0.1-0.8 mEq/L) among lithium-treated patients, and the mean desipramine level was 104.7 + 58.8 ng/mL (n = 22; range, 25-257 ng/mL). There were no significant relationships between lithium or desipramine blood levels and degree of improvement (as measured by the change in HAM-D-17 score). We found no significant differences in efficacy among these three treatment strategies among patients who had failed to respond adequately to 8 weeks of treatment with fluoxetine 20 mg/day, although the high-fluoxetine group was associated with nonsignificantly higher response rates in both partial responders and nonresponders.

Many Asian-Americans are unfamiliar with depression and its treatment. When depressed, they generally seek treatment from their primary care physicians and complain about their physical symptoms, resulting in under-recognition and under-treatment of depression. This study evaluates the effectiveness of the Chinese version of the Beck Depression Inventory (CBDI) for screening depression among Chinese-Americans in primary care. A total of 503 Chinese-Americans in the primary care clinic of a community health center were administered the CBDI for depression screening. Patients who screened positive (CBDI > or = 16) were interviewed by a psychiatrist using the Structured Clinical Interview for DSM-III-R, patient version (SCID-I/P) for confirmation of the diagnosis. Patients who screened negative (CBDI < 16) were randomly selected to be interviewed using the depression module of the SCID-I/P. The results of the SCID-I/P interview were used as the standard for evaluating the sensitivity and specificity of the CBDI. A total of 815 Chinese-Americans in a primary care clinic were approached, and 503 completed the CBDI. Seventy-six (15%) screened positive (CBDI > or = 16), and the prevalence of major depression was 19.6% by using extrapolated results from SCID-I/P interviews. When administered by a native-speaking research assistant, the CBDI has good sensitivity (.79), specificity (.91), positive predictive value (.79), and negative predictive value (.91). Despite the commonly believed tendency to focus on physical symptoms rather than depressed mood, Chinese-Americans are able to report symptoms of depression in response to a questionnaire. The CBDI, when administered by research assistants, has good sensitivity and specificity in recognizing major depression in this population. Lack of interest among Chinese-American patients in using the CBDI as a self-rating instrument has limited its use for depression screening in primary care settings.

A major depressive episode can be categorised as severe based on depressive symptoms, scores on depression rating scales, the need for hospitalisation, depressive subtypes, functional capacity, level of suicidality and the impact that the depression has on the patient. Several biological, psychological and social factors, and the presence of comorbid psychiatric or medical illnesses, impact on depression severity. A number of factors are reported to influence outcome in severe depression, including duration of illness before treatment, severity of the index episode, treatment modality used, and dosage and duration of and compliance with treatment. Potential complications of untreated severe depression include suicide, self-mutilation and refusal to eat, and treatment resistance. Several antidepressants have been studied in the treatment of severe depression. These include tricyclic antidepressants (TCAs), selective serotonin reuptake inhibitors (SSRIs), serotonin-noradrenaline (norepinephrine) reuptake inhibitors, noradrenergic and specific serotonergic antidepressants, serotonin 5-HT(2) receptor antagonists, monoamine oxidase inhibitors, and amfebutamone (bupropion). More recently, atypical antipsychotics have shown some utility in the management of severe and resistant depression. Data on the differential efficacy of TCAs versus SSRIs and the newer antidepressants in severe depression are mixed. Some studies have reported that TCAs are more efficacious than SSRIs; however, more recent studies have shown that TCAs and SSRIs have equivalent efficacy. There are reports that some of the newer antidepressants may be more effective than SSRIs in the treatment of severe depression, although the sample sizes in some of these studies were small. Combination therapy has been reported to be effective. The use of an SSRI-TCA combination, while somewhat controversial, may rapidly reduce depressive symptoms in some patients with severe depression. The combination of an antidepressant and an antipsychotic drug is promising and may be considered for severe depression with psychotic features. Although the role of cognitive behaviour therapy (CBT) in severe depression has not been adequately studied, a trial of CBT may be considered in severely depressed patients whose symptoms respond poorly to an adequate antidepressant trial, who are intolerant of antidepressants, have contraindications to pharmacotherapy, and who refuse medication or other somatic therapy. A combination of CBT and antidepressants may also be beneficial in some patients. Electroconvulsive therapy (ECT) may be indicated in severe psychotic depression, severe melancholic depression, resistant depression, and in patients intolerant of antidepressant medications and those with medical illnesses which contraindicate the use of antidepressants (e.g. renal, cardiac or hepatic disease).

Objective: Studies have identified two types of antidepressant response: true drug response and placebo pattern response. This study examined the relationship between true drug response and choline-creatine ratios in the basal ganglia of depressed patients treated with fluoxetine., Method: The authors evaluated drug-free outpatients with major depression before (N = 41) and after (N = 15) 8 weeks of fluoxetine treatment, 20 mg/day, by using proton magnetic resonance spectroscopy., Results: There was a significant difference in the degree of change from baseline to week 8 in choline-creatine ratios between the true drug response group (N = 8) and the placebo pattern response/nonresponse group (N = 7); the true drug response patients had a 20% increase in choline-creatine ratios, and the placebo pattern response/nonresponse patients had a 12% decrease in choline-creatine ratios., Conclusions: These data suggest that true drug response to fluoxetine treatment in depression may be associated with an increase in choline-creatine ratios in the basal ganglia.

Background: Major depression with comorbid anxiety disorder is associated with poor antidepressant outcome compared with major depression without comorbid anxiety disorder. The purpose of our study was to assess changes in depressive symptoms and anxiety levels in outpatients with major depression with comorbid anxiety disorder following 12 weeks of open treatment with fluvoxamine., Method: We enrolled 30 outpatients (mean +/- SD age = 39.4 +/- 11.3 years; 16 women and 14 men) with DSM-IV major depressive disorder accompanied by one or more current comorbid DSM-IV anxiety disorders in our study. Patients were treated openly with fluvoxamine initiated at 50 mg/day, with an upward titration to a maximum of 200 mg/day (mean +/- SD dose = 143 +/- 45 mg/day). Efficacy assessments included the 17-item Hamilton Rating Scale for Depression (HAM-D-17) and Clinical Global Impressions-Severity of Illness (CGI-S) and Improvement (CGI-I) scales for both depression and anxiety. Intent-to-treat analysis was used to assess outcome., Results: The mean +/- SD number of comorbid anxiety disorders per patient was 2.1 +/- 1.1. Following fluvoxamine treatment, the mean +/- SD HAM-D-17 score dropped from 20.2 +/- 3.3 to 1 1.0 +/- 7.0 (p < .0001). The mean +/- SD depression CGI-S score dropped from 4.0 +/- 0.6 to 2.4 +/- 1.1 (p < .0001), and the mean +/- SD anxiety CGI-S score decreased from 4.1 +/- 0.8 to 2.5 +/- 1.2 (p < .0001). Eighteen (60%) of the 30 patients had CGI-I scores < or = 2 for both anxiety and depression at endpoint, with 53% showing a > or = 50% reduction in HAM-D-17 scores at endpoint., Conclusion: Although preliminary, our findings suggest that fluvoxamine is effective in treating outpatients with major depression with comorbid anxiety disorder, having a significant effect on both depression and anxiety symptoms. Further double-blind, placebo-controlled trials are needed, in a larger sample, to confirm our findings.

Objectives: The purpose of this study was to assess the coping mechanisms in patients presenting for in-vitro fertilization (IVF)., Methods: We evaluated thirty consecutive couples presenting for in-vitro-fertilization. All couples were interviewed individually at first, and then together, using a semi-structured interview technique. Psychiatric diagnoses were made using the Diagnostic and Statistical Manual-IV (DSM-IV) criteria. Coping mechanisms used by the individuals were assessed using the Mechanisms of Coping Scale (MOCS). Other instruments used were Hamilton Depression Rating Scale (HAM-D-17), Hamilton Anxiety Rating Scale (HAM-A), Brief Psychiatric Rating Scale (BPRS), Self-Rating Symptom Scale (SRSS), and Eysenck Personality Inventory (EPI)., Results: The mean age of the sixty patients was 32.3 +/- 5.2 years. Fatalism was the commonest factor on the mechanisms of coping scale. Analysis of variance (ANOVA) across all factors of the MOCS for demographic factors showed that men used problem-solving mechanisms significantly more often than women (F = 3.0, df = 1, 58, p < 0.05). ANOVA across coping factors on stressors with post-hoc tests of significance revealed that individuals facing social stress used fatalism significantly more often than other coping mechanisms, while those facing career stress used problem-solving significantly more often than other coping mechanisms (F = 5.6, df = 1, 58, p < 0.05 and F = 3.04, df = 1, 58, p < 0.01 respectively). ANOVA across coping factors on HAM-D-17 scores revealed that individuals who used fatalism had significantly higher HAM-D-17 scores compared to those who did not (F = 4.4, df = 1, 58, p < 0.05). ANOVA across coping factors on HAM-A scores revealed that individuals who used escape-avoidance had significantly lower HAM-A scores than those who did not (F = 4.3, df = 1, 58, p < 0.05). ANOVA across coping factors on SRSS scores revealed that individuals who used passivity or fatalistic coping mechanisms had significantly higher scores on SRSS than who did not (F = 4.6, df = 1, 58, p < 0.05 and F = 3.5, df = 1, 58, p < 0.05)., Conclusions: Differential patterns of coping were found among the sixty individuals presenting for IVF and were associated with a variety of factors including gender, education, stressors, and levels of depression, anxiety, and overall psychopathology. Efforts to recognize and recruit the coping mechanisms of infertile individuals are likely to enhance their ability to participate effectively in treatment.
