Changes in inflammatory biomarkers are related to the antidepressant effects of Ayahuasca

July 10, 2020 / Ayahuasca, Depressive Disorders, Neuroscience, Papers, Psychology, Publications / By / , , , , , ,

Abstract

Background: Ayahuasca is a traditional Amazon brew and its potential antidepressant properties have recently been explored in scientific settings. We conducted a double-blind placebo-controlled trial of ayahuasca with treatment-resistant depression patients (n = 28) and healthy controls (n = 45).

Aims: We are evaluating the blood inflammatory biomarkers: C-reactive protein and interleukin 6, as a potential consequence of ayahuasca intake and their correlation with serum cortisol and brain-derived neurotrophic factor levels. Blood samples were collected at pre-treatment and 48 hours after substance ingestion to assess the concentration of inflammatory biomarkers, together with administration of the Montgomery-Åsberg Depression Rating Scale.

Results: At pre-treatment, patients showed higher C-reactive protein levels than healthy controls and a significant negative correlation between C-reactive protein and serum cortisol levels was revealed (rho = -0.40, n = 14). C-reactive protein in those patients was not correlated with Montgomery-Åsberg Depression Rating Scale scores. We observed a significant reduction of C-reactive protein levels across time in both patients and controls treated with ayahuasca, but not with placebo. Patients treated with ayahuasca showed a significant correlation (rho = + 0.57) between larger reductions of C-reactive protein and lower depressive symptoms at 48 hours after substance ingestion (Montgomery-Åsberg Depression Rating Scale). No significant result with respect to interleukin 6 and brain-derived neurotrophic factor was found. Furthermore, these biomarkers did not predict the antidepressant response or remission rates observed.

Conclusions: These findings enhance the understanding of the biological mechanisms behind the observed antidepressant effects of ayahuasca and encourage further clinical trials in adults with depression.

Psychedelic Treatment for Trauma-Related Psychological and Cognitive Impairment Among US Special Operations Forces Veterans

July 8, 2020 / Anxiety Disorders / PTSD, Depressive Disorders, DMT, Iboga / Ibogaine, Neuroscience, Papers, Psychiatry & Medicine, Psychology, Psychotic Disorders, Publications / By / , , , ,

Abstract

Background

U.S. Special Operations Forces Veterans are at increased risk for a variety of mental health problems and cognitive impairment associated with military service. Current treatments are lacking in effectiveness and adherence. Therefore, this study examined psychedelic treatment with ibogaine and 5-methoxy-N,N-dimethyltryptamine for trauma-related psychological and cognitive impairment among U.S. Special Operations Forces Veterans.

Method

We conducted a survey of Veterans who completed a specific psychedelic clinical program in Mexico between 2017 and 2019. Questions probed retrospective reports of mental health and cognitive functioning during the 30 days before and 30 days after treatment. A total of 65 people completed treatment during this time frame and were eligible for contact. Of these, 51 (78%) completed the survey and were included in data analyses (mean age = 40; male = 96%; married = 55%; Caucasian/White = 92%; Operation Enduring Freedom/Operation Iraqi Freedom Service = 96%).

Results

Results indicated significant and very large reductions in retrospective report of suicidal ideation (p < .001; d = −1.9), cognitive impairment (p < .001; d = −2.8), and symptoms of posttraumatic stress disorder (p < .001; d = −3.6), depression (p < .001; d = −3.7), and anxiety (p < .001; d = −3.1). Results also showed a significant and large increase in retrospective report of psychological flexibility (p < .001; d = 2.9) from before-to-after the psychedelic treatment. Increases in the retrospective report of psychological flexibility were strongly associated with retrospective report of reductions in cognitive impairment, and symptoms of posttraumatic stress disorder, depression, and anxiety (rs range −0.61 to −0.75; p < .001). Additionally, most participants rated the psychedelic experiences as one of the top five personally meaningful (84%), spiritually significant (88%), and psychologically insightful (86%) experiences of their lives.
Limitations: Several limitations should be considered including the retrospective, self-report, survey design of the study, and the lack of randomization and blinding, thus making these finding preliminary.

Conclusion

U.S. Special Operations Forces Veterans may have unique treatment needs because of the sequela of problems associated with repeated trauma exposure and the nature of the exposure. Psychedelic-assisted therapy with these under-researched psychedelics may hold unique promise for this population. However, controlled studies are needed to determine whether this treatment is efficacious in relieving mental health and cognitive impairment among U.S. Special Operations Forces Veterans.

Historic psychedelic drug trials and the treatment of anxiety disorders

December 6, 2021 / Anxiety Disorders / PTSD, Papers, Psychiatry & Medicine, Psychology, Publications / By / , , , , , ,

Abstract

Introduction: In this paper, we systematically review literature from 1940 to 2000 relating to the combined use of psychological therapies and psychedelic drugs in the treatment of ICD-10 anxiety disorders.

Methods: The databases Ovid MEDLINE(R), PsycINFO, and Multidisciplinary Association for Psychedelic Studies (MAPS) were searched for case reports and trials involving humans in the treatment of ICD-10 anxiety and related disorders. Twenty-four studies are described; four describe anxiety symptoms in diverse patient groups, 14 studies describe historic diagnoses that usefully correspond with ICD-10 anxiety disorders, six studies pooled results or failed to detail results specific to contemporary ICD-10 anxiety disorders. Two of the 24 studies reported are individual case reports while two of them were inadequate in terms of the reporting of outcome measures. Thus 20 studies were ultimately included in the summary analysis.

Results: Three of the 20 studies reviewed described improvements in anxiety by standardized measures (p < .05) and two studies found that this effect was dose related. Of the 20 studies included in the final analysis, 94 of 145 (65%) cases of “psychoneurotic anxiety reaction” as defined by Diagnostic and Statistical Manual of Mental Disorders-I showed improvement that ranged from moderate improvement to full recovery. Despite methodological inadequacies, the results from previous studies are encouraging and should be used to guide and inform further investigation.

Conclusion: The majority of studies indicate that a combination of psychedelic drug administration and psychological therapy was most beneficial. We found no study suggesting that the pharmacological action of psychedelic drugs in isolation is sufficient.

3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for victims of sexual abuse with severe post-traumatic stress disorder: an open label pilot study in Brazil

July 3, 2020 / Anxiety Disorders / PTSD, MDMA, Papers, Psychiatry & Medicine, Psychology, Publications / By / , , , , , ,

Abstract

Objective: To conduct Brazil’s first clinical trial employing 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for post-traumatic stress disorder (PTSD), given its high prevalence resulting from epidemic violence.

Methods: Of 60 volunteers, four matched the inclusion & exclusion criteria. Three patients with PTSD secondary to sexual abuse (diagnosed by the Structured Clinical Interview for DSM-IV and the Clinician Administered PTSD Scale for DSMV-4 [CAPS 4]) completed enrollment and treatment, following a standardized Multidisciplinary Association for Psychedelic Studies protocol consisting of 15 weekly therapy sessions: three with orally administered MDMA with concurrent psychotherapy and music, spaced approximately 1 month apart. CAPS-4 scores two months after the final MDMA session were the primary outcome.

Results: No serious adverse events occurred. The most frequent adverse events were somatic pains and anguish. CAPS-4 reductions were always greater than 25 points. The final scores were 61, 27, and 8, down from baseline scores of 90, 78, and 72, respectively. All reductions were greater than 30%, which is indicative of clinically significant improvement. Secondary outcomes included lower Beck Depressive Inventory scores and higher Post-Traumatic Growth Inventory and Global Assessment of Functioning scores.

Conclusions: Considering the current limitations in safe and efficacious treatments for PTSD and recent studies abroad with larger patient samples, MDMA-assisted psychotherapy could become a viable treatment in Brazil.

A randomized, double-blind, active placebo-controlled study of efficacy, safety, and durability of repeated vs single subanesthetic ketamine for treatment-resistant depression

June 26, 2020 / Depressive Disorders, Ketamine, Papers, Psychology, Publications / By / , , , ,

Abstract

The strategy of repeated ketamine in open-label and saline-control studies of treatment-resistant depression suggested greater antidepressant response beyond a single ketamine. However, consensus guideline stated the lack of evidence to support frequent ketamine administration. We compared the efficacy and safety of single vs. six repeated ketamine using midazolam as active placebo. Subjects received either six ketamine or five midazolam followed by a single ketamine during 12 days followed by up to 6-month post-treatment period. The primary end point was the change from baseline in the Montgomery-Åsberg Depression Rating Scale (MADRS) score at 24 h after the last infusion. Fifty-four subjects completed all six infusions. For the primary outcome measure, there was no significant difference in change of MADRS scores between six ketamine group and single ketamine group at 24 h post-last infusion. Repeated ketamine showed greater antidepressant efficacy compared to midazolam after five infusions before receiving single ketamine infusion. Remission and response favored the six ketamine after infusion 4 and 5, respectively, compared to midazolam before receiving single ketamine infusion. For those who responded, the median time-to-relapse was nominally but not statistically different (2 and 6 weeks for the single and six ketamine group, respectively). Repeated infusions were relatively well-tolerated. Repeated ketamine showed greater antidepressant efficacy to midazolam after five infusions but fell short of significance when compared to add-on single ketamine to midazolam at the end of 2 weeks. Increasing knowledge on the mechanism of ketamine should drive future studies on the optimal balance of dosing ketamine for maximum antidepressant efficacy with minimum exposure.

Integrating psychotherapy and psychopharmacology: psychedelic-assisted psychotherapy and other combined treatments

June 12, 2020 / Depressive Disorders, Humanities & Art, MDMA, Papers, Psychology, Publications / By / , , ,

Abstract

Introduction: Combinations of psychotherapy with antidepressants are gold-standard psychiatric treatments. They operate through complex and interactional mechanisms, not unlike the reemergent paradigm of psychedelic-assisted psychotherapy, which promising research suggests may also be highly effective in even challenging populations.
Areas covered: We review the therapeutic mechanisms behind both conventional and psychedelic paradigms, including the evolution of this knowledge and the associated explanatory frameworks. We explore how psychedelics have provided insights about psychiatric illnesses and treatments over the past decades. We discuss limitations to early explanatory models while highlighting and comparing the psychological and biological mechanisms underlying many psychiatric treatments.
Methods: A narrative review was conducted based on a search in Medline/Pubmed up to January 1st, 2020, and iterative retrieval of references from recent reviews and clinical trials.
Expert opinion: The contextual model of the common factors of psychotherapy provides a powerful perspective on psychotherapy, antidepressants, and psychedelics, as well as 3,4-methylenedioxymethamphetamine (MDMA) and ketamine. It aligns well with key tenets of psychedelic-assisted psychotherapy. Conventional antidepressants and especially psychedelics may improve the efficacy of psychotherapy via neurochemical changes and increased environmental sensitivity. Combined treatments hold significant promise for advancing the knowledge and treatment of many forms of psychopathology.

Long-term follow-up outcomes of MDMA-assisted psychotherapy for treatment of PTSD: a longitudinal pooled analysis of six phase 2 trials

January 3, 2022 / Anxiety Disorders / PTSD, MDMA, Papers / Leave a Comment / By / , , , , , , ,

Abstract

Rationale: Posttraumatic stress disorder (PTSD) is a chronic condition that has wide-ranging negative effects on an individual’s health and interpersonal relationships. Treatments with long-term benefits are needed to promote the safety and well-being of those suffering from PTSD.

Objectives: To examine long-term change in PTSD symptoms and additional benefits/harms after 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for treatment of PTSD.

Methods: Participants received two to three active doses of MDMA (75-125 mg) during blinded or open-label psychotherapy sessions with additional non-drug therapy sessions. PTSD symptoms were assessed using the Clinician-Administered PTSD Scale for DSM IV (CAPS-IV) at baseline, 1 to 2 months after the last active MDMA session (treatment exit), and at least 12 months post final MDMA session (LTFU). A mixed-effect repeated-measures (MMRM) analysis assessed changes in CAPS-IV total severity scores. The number of participants who met PTSD diagnostic criteria was summarized at each time point. Participants completed a long-term follow-up questionnaire.

Results: There was a significant reduction in CAPS-IV total severity scores from baseline to treatment exit (LS mean (SE) = – 44.8 (2.82), p < .0001), with a Cohen’s d effect size of 1.58 (95% CI = 1.24, 1.91). CAPS-IV scores continued to decrease from treatment exit to LTFU (LS mean (SE) = – 5.2 (2.29), p < .05), with a Cohen’s d effect size of 0.23 (95% CI = 0.04, 0.43). The number of participants who no longer met PTSD criteria increased from treatment exit (56.0%) to LTFU (67.0%). The majority of participants reported benefits, including improved relationships and well-being, and a minority reported harms from study participation.

Conclusions: PTSD symptoms were reduced 1 to 2 months after MDMA-assisted psychotherapy, and symptom improvement continued at least 12 months post-treatment. Phase 3 trials are investigating this novel treatment approach in a larger sample of participants with chronic PTSD.

Esketamine Nasal Spray for Rapid Reduction of Major Depressive Disorder Symptoms in Patients Who Have Active Suicidal Ideation With Intent: Double-Blind, Randomized Study (ASPIRE I)

May 12, 2020 / Depressive Disorders, Ketamine, Papers, Psychology, Publications / By / , , , , ,

Abstract

Objective: To compare esketamine to placebo, each in addition to standard-of-care treatment, for rapidly reducing major depressive disorder symptoms, including suicidal ideation.
Methods: This phase 3, double-blind, multicenter study (ASPIRE I), conducted between June 2017 and December 2018, enrolled 226 adults having major depressive disorder based on Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5) criteria, active suicidal ideation with intent, and need for psychiatric hospitalization. Patients were randomized 1:1 to esketamine 84 mg or placebo nasal spray twice-weekly for 4 weeks, each with comprehensive standard-of-care treatment (initial psychiatric hospitalization and newly initiated or optimized oral antidepressant[s] therapy). Change from baseline to 24 hours post-first dose in Montgomery-Asberg Depression Rating Scale (MADRS) total score (primary endpoint) was analyzed using analysis of covariance (ANCOVA), and change in Clinical Global Impression of Severity of Suicidality Revised version (CGI-SS-r; key secondary endpoint) score was analyzed using ANCOVA on ranks with treatment difference estimated using the Hodges-Lehmann estimate.
Results: Greater improvement in MADRS total score was observed with esketamine + standard-of-care versus placebo + standard-of-care at 24 hours (least-squares mean difference [SE]: -3.8 [1.39]; 95% CI, -6.56 to -1.09; 2-sided P = .006), as well as at earlier (4 hours) and later time points during 4-week double-blind treatment. The difference between groups in the severity of suicidality was not statistically significant (median of treatment difference [95% CI]: 0.0 [-1.00 to 0.00]; 2-sided P = .107). The most common adverse events among esketamine-treated patients were dizziness, dissociation, headache, nausea, and somnolence.
Conclusions: These findings demonstrate rapid and robust efficacy of esketamine nasal spray in reducing depressive symptoms in severely ill patients with major depressive disorder who have active suicidal ideation with intent.

MDMA-assisted psychotherapy for people diagnosed with treatment-resistant PTSD: what it is and what it isn’t

May 12, 2020 / Anxiety Disorders / PTSD, MDMA, Papers, Psychology, Publications / By /

Abstract

Background

PTSD is a chronic condition with high rates of comorbidity, but current treatment options are limited and not always effective. One novel approach is MDMA-assisted psychotherapy for people diagnosed with treatment-resistant PTSD, where MDMA is used as a catalyst to facilitate trauma processing during psychotherapy. The aim was to review all current research into MDMA-assisted psychotherapy for PTSD.

Methods

Articles were identified through PubMed and Science Direct for items published up to 31st March 2019 using terms “treatments for PTSD”, “drug treatments for PTSD”, “MDMA”, “MDMA pathway”, “MDMA-assisted psychotherapy” and “MDMA-assisted psychotherapy for PTSD”. Articles were identified through Google Scholar and subject-specific websites. Articles and relevant references cited in those articles were reviewed.

Results

Small-scale studies have shown reduced psychological trauma, however there has been widespread misunderstanding of the aims and implications of this work, most commonly the notion that MDMA is a ‘treatment for PTSD’, which to date has not been researched. This has harmful consequences, namely dangerous media reporting and impeding research progression in an already controversial field.

Conclusions

MDMA-assisted psychotherapy may help people who have experienced psychological trauma and who have not been able to resolve their problems through existing treatments, however more research is needed. If this is to get appropriate research attention, we must report this accurately and objectively.

Psilocybin: from ancient magic to modern medicine

May 12, 2020 / Anthropology & Sociology, Anxiety Disorders / PTSD, Biology & Ethnobotany, Depressive Disorders, Humanities & Art, Mushrooms / Psilocybin, Papers, Psychology, Publications / By /

Abstract

Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine) is an indole-based secondary metabolite produced by numerous species of mushrooms. South American Aztec Indians referred to them as teonanacatl, meaning “god’s flesh,” and they were used in religious and healing rituals. Spanish missionaries in the 1500s attempted to destroy all records and evidence of the use of these mushrooms. Nevertheless, a 16th century Spanish Franciscan friar and historian mentioned teonanacatl in his extensive writings, intriguing 20th century ethnopharmacologists and leading to a decades-long search for the identity of teonanacatl. Their search ultimately led to a 1957 photo-essay in a popular magazine, describing for the Western world the use of these mushrooms. Specimens were ultimately obtained, and their active principle identified and chemically synthesized. In the past 10–15 years several FDA-approved clinical studies have indicated potential medical value for psilocybin-assisted psychotherapy in treating depression, anxiety, and certain addictions. At present, assuming that the early clinical studies can be validated by larger studies, psilocybin is poised to make a significant impact on treatments available to psychiatric medicine.
