Comorbid alcohol use disorder and posttraumatic stress disorder: A proof-of-concept randomized placebo-controlled trial of buprenorphine and naltrexone combination treatment.

BACKGROUND: Effective pharmacologic treatments for comorbid alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD) are lacking. Kappa (κ) opioid receptor antagonists may address this unmet need. Buprenorphine is a κ-opioid antagonist and a partial agonist of mu (µ) opioid receptors. Whereas naltrexone blocks all µ-mediated effects combining it with buprenorphine yields a pharmacologic net effect of opioid receptor antagonism. Because no κ-opioid receptor antagonist it available for clinical use, we tested this combination in a proof-of-concept study. METHODS: Consenting participants were enrolled in a Phase II, multisite, double-blind, randomized, placebo-controlled trial evaluating the effectiveness of sublingual (SL) buprenorphine combined with extended-release (XR) injectable naltrexone for the treatment of comorbid AUD and PTSD. Eligible participants (n = 75) were randomized (1:1:1) to receive either buprenorphine 2 mg/day plus naltrexone-XR (n = 35), buprenorphine 8 mg/day plus naltrexone-XR (n = 6) or SL plus injectable placebo (n = 34) for 12 weeks. The buprenorphine 8 mg/day plus naltrexone-XR arm was dropped early in the trial due to the negative impact of COVID-19 on enrollment. A binary primary outcome of response at week 8 was defined as a decrease from baseline of ≥10 points on the past week Clinician-Administered PTSD Scale (CAPS-5) and a reduction of ≥1 of past month alcohol risk level, as defined by the World Health Organization (WHO) and measured by the Timeline Follow-Back. RESULTS: Based on the results of a futility analysis, enrollment was stopped prior to reaching the initial goal of 90 participants. At the week eight primary timepoint, there were no statistically significant differences between buprenorphine plus naltrexone-XR and placebo group for the primary composite outcome (OR = 0.63; p-value = 0.52), or the subcomponents of the PTSD outcome (OR = 0.76; p-value = 0.69) and AUD outcome (OR = 0.17; p-value = 0.08). The placebo arm had a significantly higher proportion of participants with ≥1 WHO risk level reduction than the buprenorphine plus naltrexone-XR arm (OR = 0.18, p value = 0.02). CONCLUSIONS: This is the first study to evaluate the potential of κ-opioid receptor antagonism for the treatment of comorbid AUD and PTSD. The combination of buprenorphine and naltrexone-XR showed no significant improvement over placebo for the composite, PTSD, or alcohol measures.

Biomarker Response to Mindfulness Intervention in Veterans Diagnosed with Post-traumatic Stress Disorder.

Objectives: This study evaluates the effects of treatment with mindfulness-based stress reduction (MBSR) compared to the active control, present-centered group therapy (PCGT), on morning plasma cortisol, interleukin-6 (IL-6), and C-reactive protein (CRP) in veterans diagnosed with post-traumatic stress disorder (PTSD). Methods: In a post hoc exploratory analysis, we pooled biomarkers and clinical outcomes of mindfulness, PTSD, and depression from two randomized controlled trials comparing MBSR (n = 104) to PCGT (n = 106) in U.S. military veterans diagnosed with PTSD. Linear mixed-effects modeling was used to evaluate associations between changes in biomarkers and clinical outcomes from baseline to 9-week primary endpoint and 16-week follow-up endpoint. Results: Cortisol levels were inversely related to self-reported PTSD symptoms at baseline (p = 0.02). Cortisol increased from baseline to 9-week endpoint for both groups, but significantly less so in the MBSR group compared to PCGT group (mean difference 1.69 ± 0.8 SE; p = 0.035). Changes in IL-6 and CRP did not differ between groups at either baseline or week 9. From baseline to week 9, increased mindfulness was significantly associated with increased cortisol (p = 0.02) and decreased PTSD and depression severity (p < 0.01). Increased IL-6 and CRP were significantly associated with decreased PTSD severity (p < 0.05), but not depression. Pooled analysis corroborated earlier findings that MBSR is significantly better than PCGT in improving clinical outcomes. Increased mindfulness was strongly associated with improved symptoms. Conclusions: Increased mindfulness is associated with a recalibration of cortisol levels which may be indicative of therapeutic response, especially in patients with lower baseline cortisol. Furthermore, mindfulness-based practices improve symptoms of PTSD and depression in a significant correlation with self-reported levels of mindfulness.

A Randomized Controlled Trial Evaluating the Effectiveness of Supported Employment Integrated in Primary Care.

OBJECTIVES: Mental health issues can cause serious problems in occupational functioning, including higher rates of unemployment. Individual placement and support (IPS) is an evidence-based supported employment intervention that is typically integrated within a mental health setting; however, many primary care patients view referral to a mental health clinic as stigmatizing. Thus, this study examined whether delivery of IPS in a primary care setting provides an effective treatment option and avoids unnecessary delays in obtaining competitive employment. METHODS: U.S. military veterans (N=119) who had a diagnosis in a broad range of nonpsychotic psychiatric disorders and who were receiving care from Veterans Health Administration (VHA) patient-aligned care teams were prospectively randomly assigned to IPS (N=58) or standard VHA non-IPS vocational rehabilitation (VR) (N=61). The primary outcome was achievement of steady worker status, defined as holding a competitive job for ≥6 months of the 12-month follow-up. RESULTS: As hypothesized, a significantly greater proportion of IPS participants achieved steady worker status (45%), compared with VR participants (25%) (p=0.02; odds ratio=2.49, 95% confidence interval=1.14-5.43). On average, the IPS participants worked significantly more weeks (p=0.003) and earned significantly more income (p=0.033) from competitive jobs, compared with VR participants. CONCLUSIONS: The results provide supporting evidence for offering IPS within primary care with the aim of restoring meaningful and sustained competitive employment for veterans living with a mental disorder. Such modifications could improve veterans' vocational outcomes, moving a significantly greater number of disabled veterans back to full and productive lives in the community.

A Randomized, Placebo-Controlled Trial of Mirtazapine for the Treatment of Posttraumatic Stress Disorder in Veterans.

OBJECTIVE: The aim of this study was to determine the efficacy of mirtazapine, a tetracyclic antidepressant, as monotherapy for the treatment of posttraumatic stress disorder (PTSD). METHODS: This multisite, randomized, double-blind, placebo-controlled trial was conducted between April 2006 and November 2010 at the Tuscaloosa and Birmingham Veterans Affairs Medical Centers in Alabama. US military veterans who met DSM-IV criteria for PTSD were randomly assigned to placebo (n = 39) or mirtazapine (n = 39) titrated up to 45 mg/d for an 8-week double-blind period followed by an 8-week open-label phase of mirtazapine treatment. The primary outcome efficacy measure was the Structured Interview for Posttraumatic Stress Disorder (SIP). Secondary measures included other measures of PTSD, depression, and sleep. Analyses of treatment groups involved mixed-model procedures using a random intercept to test the hypotheses that mirtazapine would be more effective than placebo in reducing symptoms of PTSD and depression and improving quality of sleep. RESULTS: Seventy-eight participants were randomized with 61 completing the 8-week controlled phase and 48 completing the open-label phase. No significant differences were observed between groups on the primary outcome of SIP scores during the controlled phase (P = .418). In secondary outcomes, significant improvements per the Clinical Global Impressions-Improvement scale were found for the mirtazapine group compared to the placebo group (P = .041). The 8-week open-label phase demonstrated significant symptom improvement in SIP total score (P = .0003) and in scores on the SIP re-experiencing (P = .0007), avoidance (P = .0309), and hyperarousal (P = .0014) subscales. There were no significant differences in the occurrence of adverse events between groups. CONCLUSIONS: This study did not show efficacy of mirtazapine monotherapy in the treatment of PTSD. Identification of more effective treatments, either as monotherapy or adjunctive, for PTSD is imperative. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00302107.

Impact of Concurrent Posttraumatic Stress Disorder on Outcomes of Antipsychotic Augmentation for Major Depressive Disorder With a Prior Failed Treatment: VAST-D Randomized Clinical Trial.

OBJECTIVE: To determine whether concurrent posttraumatic stress disorder (PTSD) should affect whether to augment or switch medications when major depressive disorder (MDD) has not responded to a prior antidepressant trial. METHODS: Patients at 35 Veterans Health Administration medical centers from December 2012 to May 2015 with nonpsychotic MDD (N = 1,522) and a suboptimal response to adequate antidepressant treatment were randomly assigned to 3 "next step" treatments: switching to bupropion, augmenting the current antidepressant with bupropion, and augmenting with the antipsychotic aripiprazole. Blinded ratings with the 16-item Quick Inventory of Depressive Symptomatology-Clinician Rated (QIDS-C16) determined remission and response by 12 weeks and relapse after remission. Survival analyses compared treatment effects in patients with concurrent PTSD diagnosed with the Mini-International Neuropsychiatric Interview (n = 717, 47.1%) and those without PTSD (n = 805, 52.9%). RESULTS: Patients diagnosed with PTSD showed more severe depressive symptoms at baseline and were less likely to achieve either remission or response by 12 weeks. Augmentation with aripiprazole was associated with greater likelihood of achieving response (68.4%) than switching to bupropion (57.7%) in patients with PTSD (relative risk [RR] = 1.26; 95% CI, 1.01-1.59) as well as in patients without PTSD (RR = 1.29; 95% CI, 1.05-1.97) (78.9% response with aripiprazole augmentation vs 66.9% with switching to bupropion). Treatment comparisons with the group receiving augmentation with bupropion were not significant. There was no significant interaction between treatment group and PTSD on remission (P = .70), response (P = .98), or relapse (P = .15). CONCLUSIONS: Although PTSD was associated with poorer overall outcomes, the presence of concurrent PTSD among Veterans in this trial did not affect the comparative effectiveness of medications on response, remission, or relapse after initial remission.

The methods and baseline characteristics of a VA randomized controlled study evaluating supported employment provided in primary care patient aligned care teams.

BACKGROUND: This article describes the design and baseline sample of a single-site trial comparing Individual Placement and Support (IPS) supported employment delivered within a Veterans Health Administration (VHA) primary care Patient Aligned Care Team (PACT) to treatment-as-usual vocational rehabilitation (TAU-VR) that includes transitional work. METHODS: Unemployed U.S. military veterans receiving care in a VHA PACT who were seeking competitive work, otherwise eligible for vocational rehabilitation, and diagnosed with a mental health condition other than a psychotic or bipolar I disorder were prospectively randomized to receive either IPS or TAU-VR. Employment outcomes and measures of quality of life, self-esteem, and community reintegration are being collected for 12 months. RESULTS: The participant sample (n = 119) is comprised of 17.6% female, 73.1% African-Americans, and 1.7% Hispanic. Average age is 38.2 (SD ± 8.41) years; 80.7% served in the military since 2001; 78% are receiving or applying for U.S. Department of Veterans Affairs (VA) service-connected disability; 26.9% have not held a competitive job in the past 3 years; and the average length of pre-randomization unemployment is 1.4 (SD ± 2.3) years. CONCLUSIONS: Unique design features include evaluating the efficacy of evidenced-based IPS within the primary care setting, having broad diagnostic eligibility, and defining the primary outcome criterion as "steady employment", i.e. holding a competitive job for ≥26 weeks of the 12-month follow-up period. The findings illustrate the characteristics of a primary care veteran sample in need of employment services. TRIAL REGISTRATION: www.clinicaltrials.gov Identifier: NCT02400736.

Effect of Antidepressant Switching vs Augmentation on Remission Among Patients With Major Depressive Disorder Unresponsive to Antidepressant Treatment: The VAST-D Randomized Clinical Trial.

IMPORTANCE: Less than one-third of patients with major depressive disorder (MDD) achieve remission with their first antidepressant. OBJECTIVE: To determine the relative effectiveness and safety of 3 common alternate treatments for MDD. DESIGN, SETTING, AND PARTICIPANTS: From December 2012 to May 2015, 1522 patients at 35 US Veterans Health Administration medical centers who were diagnosed with nonpsychotic MDD, unresponsive to at least 1 antidepressant course meeting minimal standards for treatment dose and duration, participated in the study. Patients were randomly assigned (1:1:1) to 1 of 3 treatments and evaluated for up to 36 weeks. INTERVENTIONS: Switch to a different antidepressant, bupropion (switch group, n = 511); augment current treatment with bupropion (augment-bupropion group, n = 506); or augment with an atypical antipsychotic, aripiprazole (augment-aripiprazole group, n = 505) for 12 weeks (acute treatment phase) and up to 36 weeks for longer-term follow-up (continuation phase). MAIN OUTCOMES AND MEASURES: The primary outcome was remission during the acute treatment phase (16-item Quick Inventory of Depressive Symptomatology-Clinician Rated [QIDS-C16] score ≤5 at 2 consecutive visits). Secondary outcomes included response (≥50% reduction in QIDS-C16 score or improvement on the Clinical Global Impression Improvement scale), relapse, and adverse effects. RESULTS: Among 1522 randomized patients (mean age, 54.4 years; men, 1296 [85.2%]), 1137 (74.7%) completed the acute treatment phase. Remission rates at 12 weeks were 22.3% (n = 114) for the switch group, 26.9% (n = 136)for the augment-bupropion group, and 28.9% (n = 146) for the augment-aripiprazole group. The augment-aripiprazole group exceeded the switch group in remission (relative risk [RR], 1.30 [95% CI, 1.05-1.60]; P = .02), but other remission comparisons were not significant. Response was greater for the augment-aripiprazole group (74.3%) than for either the switch group (62.4%; RR, 1.19 [95% CI, 1.09-1.29]) or the augment-bupropion group (65.6%; RR, 1.13 [95% CI, 1.04-1.23]). No significant treatment differences were observed for relapse. Anxiety was more frequent in the 2 bupropion groups (24.3% in the switch group [n = 124] vs 16.6% in the augment-aripiprazole group [n = 84]; and 22.5% in augment-bupropion group [n = 114]). Adverse effects more frequent in the augment-aripiprazole group included somnolence, akathisia, and weight gain. CONCLUSIONS AND RELEVANCE: Among a predominantly male population with major depressive disorder unresponsive to antidepressant treatment, augmentation with aripiprazole resulted in a statistically significant but only modestly increased likelihood of remission during 12 weeks of treatment compared with switching to bupropion monotherapy. Given the small effect size and adverse effects associated with aripiprazole, further analysis including cost-effectiveness is needed to understand the net utility of this approach.

An Open Label Pilot Study of Adjunctive Asenapine for the Treatment of Posttraumatic Stress Disorder.

OBJECTIVE: Selective serotonin reuptake inhibitors (SSRIs) remain the first-line treatment for posttraumatic stress disorder (PTSD). However, adjunctive atypical antipsychotics are often used to target residual or refractory symptoms. Asenapine is a novel atypical antipsychotic that possesses a high serotonin (5-HT2A) to dopamine (D2) affinity ratio and alpha-adrenergic antagonism, which may be advantageous in treating PTSD. This pilot study aimed to identify the therapeutic potential of asenapine as an adjunctive treatment for PTSD. METHOD: Eighteen subjects initiated treatment in this single-site prospective, open-label, 12-week trial of flexibly-dosed asenapine in Veterans with PTSD who had not responded to an adequate course of treatment with an SSRI, venlafaxine, or mirtazapine. Subjects remained on their antidepressant medication and were started on adjunctive asenapine 5 mg sublingual at bedtime, which was gradually titrated to a maximum of 10 mg twice per day, as tolerated. The primary outcome measure was the Clinician Administered PTSD Scale (CAPS) for DSM-IV. RESULTS: Fifteen subjects finished at least 4 weeks and eleven completed the 12 week study. There was a significant and clinically meaningful decrease in CAPS from baseline (77.56 ± 14.48) to week 4 (48.7 ± 30.6), and to week 12 (35.3 ± 19.7). Six participants experienced adverse events possibly related to asenapine; however, only three participants discontinued early due to related adverse events. CONCLUSION: This pilot study demonstrated that adjunctive treatment with asenapine may provide additional benefit to some patients experiencing residual PTSD symptoms in spite of optimal antidepressant therapy. A larger efficacy study may be warranted.

Characteristics of U.S. Veteran Patients with Major Depressive Disorder who require "next-step" treatments: A VAST-D report.

OBJECTIVE: Finding effective and lasting treatments for patients with Major Depressive Disorder (MDD) that fail to respond optimally to initial standard treatment is a critical public health imperative. Understanding the nature and characteristics of patients prior to initiating "next-step" treatment is an important component of identifying which specific treatments are best suited for individual patients. We describe clinical features and demographic characteristics of a sample of Veterans who enrolled in a "next-step" clinical trial after failing to achieve an optimal outcome from at least one well-delivered antidepressant trial. METHODS: 1522 Veteran outpatients with nonpsychotic MDD completed assessments prior to being randomized to study treatment. Data is summarized and presented in terms of demographic, social, historical and clinical features and compared to a similar, non-Veteran sample. RESULTS: Participants were largely male and white, with about half unmarried and half unemployed. They were moderately severely depressed, with about one-third reporting recent suicidal ideation. More than half had chronic and/or recurrent depression. General medical and psychiatric comorbidities were highly prevalent, particularly PTSD. Many had histories of childhood adversity and bereavement. Participants were impaired in multiple domains of their lives and had negative self-worth. LIMITATIONS: These results may not be generalizable to females, and some characteristics may be specific to Veterans of US military service. There was insufficient data on age of clinical onset and depression subtypes, and three novel measures were not psychometrically validated. CONCLUSIONS: Characterizing VAST-D participants provides important information to help clinicians understand features that may optimize "next-step" MDD treatments.

Impact of social challenges on gaining employment for veterans with posttraumatic stress disorder: an exploratory moderator analysis.

OBJECTIVE: To explore whether psychosocial challenges impact effects of vocational rehabilitation in Veterans with Posttraumatic Stress Disorder (PTSD). METHODS: A post hoc exploratory analysis of possible moderators of treatment was conducted on outcomes from a randomized, controlled trial of Individual Placement and Support in Veterans with PTSD. RESULTS: When examining groups within each moderator, there was a greater IPS supportive employment benefit in gaining competitive employment for those with inadequate transportation (number needed to treat [NNT] = 1.5) and inadequate housing (NNT = 1.5) compared with the main finding of the pilot study (NNT = 2.07). Compared with the main finding of the pilot study, there was no greater advantage of IPS for those with adequate transportation (NNT = 2.4) or adequate housing (NNT = 2.4). Compared with the main finding in the pilot study, those without a family care burden had a greater benefit from IPS (NNT = 1.4) and those with family care burden had a reduced treatment effect (NNT = 3.3). CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: These results are exploratory and are not intended to guide clinical decision-making, but rather offer a potentially useful strategy in the design of larger trials of IPS.

Prescribing in prison: minimizing psychotropic drug diversion in correctional practice.

Correctional facilities are a major provider of mental health care throughout the United States. In spite of the numerous benefits of providing care in this setting, clinicians are sometimes concerned about entering into correctional care because of uncertainty in prescribing practices. This article provides an introduction to prescription drug use, abuse, and diversion in the correctional setting, including systems issues in prescribing, commonly abused prescription medications, motivation for and detection of prescription drug abuse, and the use of laboratory monitoring. By understanding the personal and systemic factors that affect prescribing habits, the clinician can develop a more rewarding correctional practice and improve care for inmates with mental illness.

Effect of concurrent substance use disorder on the effectiveness of single and combination antidepressant medications for the treatment of major depression: an exploratory analysis of a single-blind randomized trial.

BACKGROUND: The co-occurrence of substance use disorder (SUD) and major depressive disorder (MDD) is common and is often thought to impair response to antidepressant therapy. These patients are often excluded from clinical trials, resulting in a significant knowledge gap regarding optimal pharmacotherapy for the treatment of MDD with concurrent SUD. METHODS: In the Combining Medications to Enhance Depression Outcomes study, 665 adult outpatients with chronic and/or recurrent MDD were prospectively treated with either escitalopram monotherapy (escitalopram and placebo) or an antidepressant combination (venalfaxine-XR and mirtazapine or escitalopram and bupropion-SR). Participants with MDD and concurrent SUD (13.1%) were compared to those without SUD (86.9%) on sociodemographic and clinical characteristics at baseline and treatment response at 12- and 28-week endpoints. RESULTS: The participants with MDD and SUD were more likely to be male and have current suicidal thoughts/plans, and had a greater lifetime severity and number of suicide attempts, and a higher number of concurrent Axis I disorders, particularly concurrent anxiety disorders. There were no significant differences between the MDD with or without SUD groups in terms of dose, time in treatment, response or remission at week 12 and 28. Furthermore, no significant differences in response or remission rates were noted between groups on the basis of the presence or absence of SUD and treatment assignment. CONCLUSIONS: Although significant baseline sociodemographic and clinical differences exist, patients with MDD and concurrent SUD are as likely to respond and remit to a single or combination antidepressant treatment as those presenting without SUD.

Encountering suicide: the experience of psychiatric residents.

OBJECTIVE: The authors sought to determine how often psychiatric residents encountered completed suicide, how it affected them, and what supports were available and most useful to them. METHODS: Psychiatric residents completed questionnaires about their encounters with completed suicide during residency. Questionnaire items asked about the resident's relationship to the deceased, the impact of the suicide on the resident, what supports were available and useful to residents, and whether residents had received education about suicide. Postgraduate education directors were similarly surveyed about their programs. RESULTS: Of 197 respondents, 61.4% had encountered one or more completed suicides during their residency. Of the suicides, 61% were by patients and 16.5% by a colleague, friend, or relative; 22.3% of the residents had encountered both. The most common context was suicide by a patient the resident had seen on call or in consultation; next was suicide by a fellow physician. The greatest impact on residents was on their emotional health, followed by how they assess patients and their medicolegal view of psychiatry. Friends and fellow residents were identified as significant supports. Residents were reluctant to use employee assistance programs, citing confidentiality and insurance issues. Only one-third of residents received education on the impact of suicide on trainees. Postgraduate education directors' responses closely reflected those of residents. Only one-third of postgraduate education directors reported having a policy in place in the event of suicide. CONCLUSIONS: Suicide is a commonly encountered, stressful event for trainees. Additional supports, education, and policies should be implemented to address this issue.
