ABSTRACT

BACKGROUND: Antidepressant-induced sexual dysfunction affects approximately 50% of patients taking antidepressants. Previous research has explored sildenafil's effectiveness in treating various forms of erectile dysfunction, but there is no research supporting sildenafil's use for improving the quality of life for patients with sexual dysfunction linked to antidepressant use. The authors of this article aimed to assess the improvements in quality of life in patients taking sildenafil to treat antidepressant-induced sexual dysfunction. METHODS: One hundred and two out of 2,239 male and female patients in the follow-up phase of the Sequenced Treatment Alternatives to Relieve Depression antidepressant trials who complained of sexual dysfunction were given sildenafil, 50 to 100 mg, as needed. After 12 months, we measured patients' change in libido, sexual drive, family relationships, overall well-being, satisfaction with treatment, and overall contentment with items on the 17-item Hamilton Depression Rating Scale, Quality of Life Enjoyment and Satisfaction Questionnaire, 30-item Inventory of Depressive Symptoms, and 12-item Short Form Health Survey. RESULTS: There was a significant association between sildenafil use and improvement in libido and sexual drive by month 6. There was no significant improvement in the quality-of-life scores we examined, but treatment satisfaction and overall contentment increased over time. CONCLUSIONS: Despite no direct association with sildenafil use and quality-of-life scores, sildenafil may be a beneficial treatment for antidepressant-induced sexual dysfunction. A double-blind, placebo-controlled study of sildenafil in antidepressant-induced sexual dysfunction is needed to further explore its potential benefits.

ABSTRACT

The selection of appropriate subjects is a critical element of successful clinical trials. Failure to properly identify, select, and retain subjects in clinical trials of antidepressant medications may affect the ability to show separation from placebo. Little is known about which type of site, academic or nonacademic, is superior in selecting and retaining appropriate subjects. In the present investigation, the authors conducted a retrospective analysis comparing the performance of academic and nonacademic sites in selecting and retaining appropriate subjects in a recently completed multi-site clinical study of aripiprazole augmentation. The authors used a set of operationalized criteria called the SAFER to identify appropriate study subjects. No significant differences were found in rates of SAFER interview passing, study completion, and clinical outcomes between academic and nonacademic sites. Our findings suggest that academic and nonacademic sites are equally effective in their ability to identify and retain appropriate study participants.

ABSTRACT

OBJECTIVE: To examine the prevalence of the C677T polymorphism of the methylene tetrahydrofolate reductase (MTHFR) gene and the A2756G polymorphism of methionine synthase (MS), and their impact on antidepressant response. METHODS: We screened 224 subjects (52% female, mean age 39 ± 11 years) with SCID-diagnosed major depressive disorder (MDD), and obtained 194 genetic samples. 49 subjects (49% female, mean age 36 ± 11 years) participated in a 12-week open clinical trial of fluoxetine 20-60 mg/day. Association between clinical response and C677T and A2756G polymorphisms, folate, B12, and homocysteine was examined. RESULTS: Prevalence of the C677T and A2756G polymorphisms was consistent with previous reports (C/C = 41%, C/T = 47%, T/T = 11%, A/A = 66%, A/G = 29%, G/G = 4%). In the fluoxetine-treated subsample (n = 49), intent-to-treat (ITT) response rates were 47% for C/C subjects and 46% for pooled C/T and T/T subjects (nonsignificant). ITT response rates were 38% for A/A subjects and 60% for A/G subjects (nonsignificant), with no subjects exhibiting the G/G homozygote. Mean baseline plasma B12 was significantly lower in A/G subjects compared to A/A, but folate and homocysteine levels were not affected by genetic status. Plasma folate was negatively associated with treatment response. CONCLUSION: The C677T and A2756G polymorphisms did not significantly affect antidepressant response. These preliminary findings require replication in larger samples.

ABSTRACT

UNLABELLED: Objective/Introduction: We sought to characterize the impact of the 90-item Symptom Checklist (SCL-90) subscales for paranoid ideation (PI) and psychoticism (P) in patients with major depressive disorder (MDD), on acute antidepressant response and on relapse prevention. METHODS: Subjects with Structured Clinical Interview for DSM Disorders-diagnosed nonpsychotic MDD were recruited into a clinical trial of open-label fluoxetine 10-60 mg/day for 12 weeks, followed by double-blind randomization of responders (n=262) to fluoxetine continuation or placebo for 12 months. PI and P were assessed with the patient-rated SCL-90. The association of these symptoms with response to treatment was assessed by logistic regression. RESULTS: We found significant decreases in PI and P during acute treatment phase for fluoxetine responders and nonresponders, although only 10.3% and 7.5% of patients experienced a >50% reduction in PI and P scores, respectively. Neither PI nor P scores significantly predicted time to relapse. P scores predicted a lower response rate to treatment with fluoxetine. DISCUSSION: The results of the present study suggest that there is a significant relationship between the presence of psychoticism in patients with nonpsychotic MDD, and the likelihood of overall depressive symptom improvement following a trial of monotherapy with fluoxetine. CONCLUSION: An increased burden of psychoticism in depressed subjects may confer poorer response to fluoxetine, but not increased risk of relapse among fluoxetine responders.

ABSTRACT

BACKGROUND: The optimal dose of S-adenosyl methionine (SAMe) for major depressive disorder (MDD) remains unclear. The objective of this analysis was to address whether a dose increase provided further improvement in cases of insufficient response using data from an existing randomized clinical trial. METHODS: Sixty-five patients with MDD who failed to respond to SAMe 1,600 mg/day, escitalopram 10 mg/day, or placebo for 6 weeks were treated with doubled doses of the allocated treatments for the following 6 weeks. Changes in 17-item Hamilton Depression Rating Scale, Inventory of Depressive Symptomatology-Self Rated, and Systematic Assessment for Treatment Emergent Events-Specific Inquiry were compared between the lower and higher dose treatments in each treatment group and among the higher dose treatments of SAMe, escitalopram, and placebo. RESULTS: Various depression severity scores decreased significantly for all three treatment arms during the higher dose treatment. No within-group and between-group differences were found in any of the efficacy measures when comparing the doses and treatments. There was a significant difference in reported abdominal discomfort among patients receiving the higher dose of SAMe (31.3%), compared to escitalopram (8.7%) and placebo (3.8%) (χ2=7.32, p = 0.026). LIMITATIONS: The sample size was relatively small. The study duration for dose increase was relatively short. CONCLUSIONS: Patients with MDD failing to respond to 1,600 mg/day of SAMe may improve after increasing the dose to 3,200 mg/day, but we cannot rule out the contribution of a placebo effect and time-related improvement. The risk of abdominal discomfort may be increased with higher doses of SAMe.

ABSTRACT

The neuroactive steroid 3α-5α-tetrahydroprogesterone (allopregnanolone), a metabolite of progesterone, is a positive allosteric modulator of GABAA receptors, and low levels have been implicated in the etiology of mood disorders. However, it is not known whether metabolism of progesterone to allopregnanolone varies across the menstrual cycle or is low after menopause. We hypothesized that the allopregnanolone/progesterone ratio would decrease from the follicular to luteal phase. We also hypothesized that postmenopausal women would have lower levels of progesterone and allopregnanolone but similar allopregnanolone/progesterone ratios as premenopausal women in the follicular phase. Serum fasting allopregnanolone and progesterone levels were measured by gas chromatography-mass spectrometry in ten premenopausal women at the follicular, mid-cycle, and luteal phases of the menstrual cycle and in twenty-four postmenopausal women. Although allopregnanolone and progesterone levels increased from the follicular to luteal phase, the allopregnanolone/progesterone ratio decreased 8-fold [0.33 ± 0.08 (follicular) vs 0.16 ± 0.09 (mid-cycle) vs 0.04 ± 0.007 (luteal), p = 0.0003]. Mean allopregnanolone and progesterone levels were lower in postmenopausal than premenopausal women at all menstrual cycle phases (p < 0.01). The mean allopregnanolone/progesterone ratio was similar in postmenopausal and premenopausal women in the follicular phase (0.39 ± 0.08 vs 0.33 ± 0.08, p = 0.94) but was significantly lower at mid-cycle and in the luteal phase than in postmenopausal women (p < 0.01). In conclusion, the serum allopregnanolone/progesterone ratio decreases 8-fold from the follicular to luteal phase and is lower at mid-cycle and the luteal phase than in postmenopausal women. Whether these data have implications for luteal phase and other mood disorders merits further study.

ABSTRACT

OBJECTIVE: To determine the prevalence of psychotic-like symptoms in non-psychotic major depressive disorder and to monitor the response of these symptoms to monotherapy with fluoxetine. METHODS: We reviewed the charts of 384 subjects (54.7% women; mean age 39.9±10), all outpatients diagnosed with non-psychotic major depressive disorder by the Structured Clinical Interview for DSM-IV (SCID), aged 18-65 years, with an initial 17-item Hamilton Depression (HAM-D-17) score of 16 or greater. Subjects were treated openly with fluoxetine 20 mg/day for 8 weeks. Subjects were administered the SCID-II (Structured Clinical Diagnostic Interview for Personality Disorder) prior to entering acute treatment and at the completion of the acute phase of treatment. We monitored the course of psychotic-like symptoms following this course of therapy. RESULTS: 187 subjects endorsed at least one psychotic-like symptom, including not trusting close acquaintances (item 51), picking up hidden meanings (item 52), believing that others were talking about them (item 57), magical thinking (item 60) or unusual perceptual experiences (item 62). None of these patients met criteria for delusional depression as defined by the SCID. Overall response rates were 36.4% for patients who endorsed psychotic-like symptoms, and 53.3% for those who did not endorse psychotic-like symptoms (chi-squared = 11.1, P=0.001). The decrease in psychotic-like symptoms during the course of fluoxetine monotherapy was significant (P<0.05) in both responders and non-responders to treatment. CONCLUSION: A significant percentage of patients with non-psychotic major depression endorse subtle psychotic-like symptoms, many of which abate during monotherapy with fluoxetine regardless of response of the depressive symptoms.

ABSTRACT

We examined the antidepressant efficacy and dose-response pattern of the n-3 docosahexaenoic acid (DHA). Thirty-five depressed adult outpatients (46% women; mean age 42+/-14 years) with a 17-item Hamilton-Depression Scale (HAM-D-17) score of >or=18 were randomized into one of three double-blind dosing arms for 12 weeks. Group A (n=14): 1 g/day of oral DHA; Group B (n=11): 2 g/day; and Group C (n=10): 4 g/day. We measured HAM-D-17 scores, plasma DHA, eicosapentaenoic acid (EPA), and n-6/n-3 ratio. Completer response rates (>or=50% decrease in HAM-D-17 score) were 83% for Group A, 40% for Group B, and 0% for Group C; Groups A and B had significant decreases in HAM-D-17 scores (p<0.05). For completers and intent-to-treat subjects, plasma DHA increased significantly (p<0.05), EPA had little change (p>0.05), and n-6/n-3 decreased significantly (p<0.05). DHA may be effective for depression at lower doses.

ABSTRACT

Sexual dysfunction, which may affect any part of the sexual response cycle (e.g., libido, arousal, and orgasm), is a highly prevalent condition among women and is associated with significant negative consequences for quality of life. Unfortunately, few effective traditional agents are available to treat this condition, especially in the postmenopausal cohort. It is therefore not surprising that many women seek alternative treatments for relief. The authors review popular alternative treatments for sexual dysfunction, emphasizing randomized, placebo-controlled trials when possible.

ABSTRACT

Objective. We sought to demonstrate that maca root may be an effective treatment for antidepressant-induced sexual dysfunction (AISD) in women. Method. We conducted a 12-week, double-blind, placebo-controlled trial of maca root (3.0 g/day) in 45 female outpatients (mean age of 41.5 ± 12.5 years) with SSRI/SNRI-induced sexual dysfunction whose depression remitted. Endpoints were improvement in sexual functioning as per the Arizona Sexual Experience Scale (ASEX) and the Massachusetts General Hospital Sexual Function Questionnaire (MGH-SFQ). Results. 45 of 57 consented females were randomized, and 42 (30 premenopausal and 12 postmenopausal women) were eligible for a modified intent-to-treat analysis based on having had at least one postmedication visit. Remission rates by the end of treatment were higher for the maca than the placebo group, based on attainment of an ASEX total score ≤ 10 (9.5% for maca versus 4.8% for placebo), attaining an MGH-SFQ score ≤ 12 (30.0% for maca versus 20.0% for placebo) and reaching an MGH-SFQ score ≤ 8 (9.5% for maca versus 5.0% for placebo). Higher remission rates for the maca versus placebo group were associated with postmenopausal status. Maca was well tolerated. Conclusion. Maca root may alleviate SSRI-induced sexual dysfunction in postmenopausal women. This trial is registered with NCT00568126.

ABSTRACT

We examined efficacy and safety of one specific cranial electrical stimulator (CES) device at a fixed setting in subjects with treatment-resistant major depressive disorder (MDD). Thirty subjects (57% female, mean age 48.1 ± 12.3 years) with MDD and inadequate response to standard antidepressants were randomized to 3 weeks of treatment with CES (15/500/15,000 Hz, symmetrical rectangular biphasic current of 1-4 mAmp, 40 V) or sham CES (device off) for 20 min, 5 days per week. The primary outcome measure was improvement in the 17-item Hamilton Depression Rating Scale (HAM-D-17). Adverse effects (AEs) were assessed using the Patient Related Inventory of Side Effects (PRISE). Completion rates were 88% for CES, 100% for sham. Both treatment groups demonstrated improvement of about 3-5 points in HAM-D-17 scores (p < 0.05 for both), and no significant differences were observed between groups. Remission rates were 12% for CES, and 15% for sham, a nonsignificant difference. CES was deemed safe, with good tolerability; poor concentration and malaise were the only distressing AEs that differed significantly between CES and sham (p = 0.019 and p = 0.043, respectively). Limitations include a small sample and lack of an active comparator therapy. Although both treatment groups improved significantly, this CES at the setting chosen did not separate from sham in this sample. Thus we cannot rule out that the benefit from this setting used in this particular form of CES was due to placebo effects. Since this form of CES has other settings, future studies should test these settings and compare it against other CES devices. Clinicaltrials.gov ID: NCT01325532.

ABSTRACT

BACKGROUND: Although atypical antipsychotic agents are commonly used in the treatment of psychotic depression, there are no published prospective studies on their use in this condition. The aim of this study was to assess, by interim analyses, the efficacy of the atypical antipsychotic agent olanzapine in combination with the selective serotonin reuptake inhibitor antidepressant agent fluoxetine. METHOD: We enrolled 27 patients (17 women [63.0%] and 10 men [37.0%]; mean +/- SD age: 41.2 +/- 14.7 years) with DSM-IV-defined major depressive disorder with psychotic features into an open trial of olanzapine, 5 to 20 mg/day, plus fluoxetine, 20 to 80 mg/day. Patients were assessed at each visit with the 17-item Hamilton Rating Scale for Depression and both the psychotic and mood modules of the Structured Clinical Interview for DSM-IV Axis I Disorders, Patient Edition. We are reporting the results of the first 6 weeks of treatment. RESULTS: Twenty-two (81.5%) of the 27 enrolled patients completed the 6-week open trial, and 5 (18.5%) dropped out, with only 2 (7.4%) dropping out due to side effects. Of the 27 patients, 74.1% (N = 20) met criteria for melancholic features, 14.8% (N = 4) had delusions alone, 18.5% (N = 5) had hallucinations alone, and 66.7% (N = 18) reported both delusions and hallucinations. In addition, the overall rates of response for the intent-to-treat group were as follows: depression response rate, 66.7% (N = 18); psychosis response rate, 59.3% (N = 16); psychotic depression response rate, 55.6% (N = 15); and psychotic depression remission rate, 40.7% (N = 11). CONCLUSION: The combination of olanzapine and fluoxetine appears to be a promising, safe, and effective treatment for psychotic depression. Double-blind studies are needed to confirm this impression.

ABSTRACT

OBJECTIVE: To examine the comparative antidepressant efficacy of S-adenosyl-L-methionine (SAMe) and escitalopram in a placebo-controlled, randomized, double-blind clinical trial. METHOD: One hundred eighty-nine outpatients (49.7% female, mean [SD] age = 45 [15] years) with DSM-IV-diagnosed major depressive disorder (MDD) were recruited from April 13, 2005, to December 22, 2009, at the Massachusetts General Hospital and at Butler Hospital. Patients were randomized for 12 weeks to SAMe 1,600-3,200 mg/d, escitalopram 10-20 mg/d, or placebo. Doses were escalated at 6 weeks in the event of nonresponse. The main outcome measure was the 17-item Hamilton Depression Rating Scale (HDRS-17). Tolerability was assessed by the Systematic Assessment for Treatment of Emergent Events-Specific Inquiry (SAFTEE-SI). RESULTS: All 3 treatment arms demonstrated a significant improvement of about 5-6 points in HDRS-17 scores (P < .001 for all), and no significant differences were observed between the treatment arms (P > .05 for all). Response rates in the intent-to-treat sample were 36% for SAMe, 34% for escitalopram, and 30% for placebo. Remission rates were 28% for SAMe, 28% for escitalopram, and 17% for placebo. No comparisons between treatment groups attained significance (P > .05 for all). Tolerability was good, with gastrointestinal side effects (19% for stomach discomfort and 20% for diarrhea) as the most common in the SAMe arm. Significant differences were observed between treatment groups for dizziness, anorgasmia, diminished mental acuity, and hot flashes (P < .05 for all). CONCLUSIONS: The results fail to support an advantage over placebo for either the investigational treatment SAMe or the standard treatment escitalopram for MDD.

ABSTRACT

OBJECTIVE: To investigate the specific effect of adjunctive aripiprazole on sexual function in patients with major depressive disorder and a history of an inadequate response to antidepressant medication by controlling for improvement in depressive symptoms as measured by improvement in Montgomery-Asberg Depression Rating Scale (MADRS) total scores. METHOD: For this post hoc analysis, data were pooled from 3 multicenter, randomized, double-blind, placebo-controlled aripiprazole augmentation studies (CN138-139: June 2004-April 2006; CN138-163: September 2004-December 2006; and CN138-165: March 2005-April 2008). Outpatients who met DSM-IV-TR criteria for a major depressive episode that had lasted ≥8 weeks with an inadequate response to prospective antidepressant treatment were randomized to adjunctive aripiprazole or placebo for 6 weeks. Sexual functioning was assessed using the Massachusetts General Hospital Sexual Functioning Inventory (MGH-SFI). To assess whether adjunctive aripiprazole improves sexual functioning directly, rather than as an indirect effect of improvement in depression symptoms, the mean change in MGH-SFI item scores and overall improvement scores was assessed using analysis of covariance, with double-blind baseline and change in MADRS total score as covariates. Correlations between MGH-SFI items and MADRS total score and prolactin levels were also assessed. RESULTS: The analysis included 1,092 subjects (n=737 female and n=355 male). In the total population, adjunctive aripiprazole demonstrated statistically significant greater improvements versus placebo on the MGH-SFI item "interest in sex" (-0.34 vs -0.18, P<.05). In males, no significant treatment differences were observed. In females, improvements in sexual functioning with adjunctive aripiprazole versus placebo were found on the MGH-SFI items "interest in sex" (-0.41 vs -0.21, P<.05) and "sexual satisfaction" (-0.44 vs -0.25, P<.05). CONCLUSIONS: Aripiprazole adjunctive to antidepressant treatment can have some beneficial effects on sexual functioning in patients with major depressive disorder who respond inadequately to standard antidepressant treatment; the benefits in women were specific to sexual interest and satisfaction and were independent of the improvement in depressive symptoms.

ABSTRACT

OBJECTIVE: To examine the efficacy and tolerability of ethyl-eicosapentaenoate (EPA-E) monotherapy for major depressive disorder (MDD). METHOD: Fifty-seven adults with DSM-IV MDD were randomly assigned from January 2003 until June 2006 to receive 1 g/d of eicosapentaenoic acid (EPA) or placebo for 8 weeks in a double-blind, randomized, controlled pilot study. Response criteria were on the basis of the 17-item Hamilton Depression Rating Scale (HDRS-17). Subjects' plasma lipid profiles were examined by gas chromatography. RESULTS: Thirty-five subjects (63% female; mean +/- SD age = 45 +/- 13 years) were eligible for the intent-to-treat (ITT) analysis. In the ITT sample, mean +/- SD HDRS-17 scores decreased from 21.6 +/- 2.7 to 13.9 +/- 8.9 for the EPA group (n = 16) and from 20.5 +/- 3.6 to 17.5 +/- 7.5 for the placebo group (n = 19) (P = .123); the effect size for EPA was 0.55. ITT response rates were 38% (6/16) for EPA, and 21% (4/19) for placebo (P = .45). Among the 24 study completers, mean +/- SD HDRS-17 scores decreased from 21.3 +/- 3.0 to 11.1 +/- 8.1 for the EPA group and from 20.5 +/- 3.8 to 16.3 +/- 6.9 for the placebo group (P = .087); the effect size for EPA was 0.73. Completer response rates were 45% (5/11) for EPA, and 23% (3/13) for placebo (P = .39). Among EPA subjects, baseline n-6/n-3 ratio was associated with decrease in HDRS-17 score (r = -0.686, P = .030) and with treatment response (P = .032); change in n-6/n-3 ratio was associated with change in HDRS-17 score (r = .784, P = .032). Side effects, reported in 2 EPA subjects and 5 placebo subjects, were exclusively gastrointestinal, mild, and not associated with discontinuation. CONCLUSIONS: EPA demonstrated an advantage over placebo that did not reach statistical significance, possibly due to the small sample and low completer rates, which were the major study limitations.

ABSTRACT

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.

ABSTRACT

Despite the superior side effect profile of the newer antidepressants over the tricyclics and monoamine oxidase inhibitors, all newer antidepressants are associated with a wide array of side effects. Clinicians are constantly confronted with the challenge of managing these side effects in the context of minimal research to prove one management strategy is more effective than another. The purpose of this study was to examine prescribing practices regarding the management of SSRI-associated side effects in a sample of psychiatrists attending a psychopharmacology review course. A total of 439 out of 800 clinicians (55%) attending a psychopharmacology review course responded to our questionnaire that was given prior to beginning the review course, though not all respondents answered all four items on the questionnaire. Among these items were questions designed to assess clinician preference for the management of SSRI-induced side effects. As a treatment for SSRI-induced sexual dysfunction, 43% (143/330) chose adding bupropion, while 36% (120/330) opted to switch agents as their first choice; for SSRI-induced insomnia, 78% (264/326) chose adding trazodone. Switching agents was the first choice of 61% (214/353) of clinicians for managing SSRI-induced agitation, 93% (339/363) for managing SSRI-associated weight gain. In an effort to manage most SSRI-associated side effects (with the exception of sexual dysfunction and insomnia), the majority of the clinicians responding to our survey opted to switch agents rather than add a specific medication to the existing SSRI. In our opinion, this practice may reflect the relative lack of research studies on the role of adjunctive treatments in the management of SSRI-induced side effects and/or the tendency to favor monotherapy over polypharmacy.
