Repeated subcutaneous racemic ketamine in treatment-resistant depression: case series

International Clinical Psychopharmacology September 1, 2022 Joseph C.W. Tham, André Do, Jason Fridfinnson et al.

Interest in the use of parenteral ketamine has been increasing over the last 2 decades for the management of treatment-resistant depression (TRD). While intravenous (IV) ketamine has been the most common parenteral route of administration, subcutaneous (SC) and intramuscular options have been described. We developed a clinical treatment protocol for the use of repeated SC racemic ketamine...

Association of intranasal esketamine, a novel ‘standard of care’ treatment and outcomes in the management of patients with treatment-resistant depression: protocol of a prospective cohort observational study of naturalistic clinical practice

BMJ Open September 1, 2022 Gustavo Vazquez, Gilmar Gutierrez, Joshua D. Rosenblat et al. 6 citations

INTRODUCTION: Esketamine is the S-enantiomer of racemic ketamine and has been approved by the Food and Drug Administration for the management of treatment resistant depression, demonstrating effective and long-lasting benefits. The objective of this observational study is to elucidate the association of intranasal (IN) esketamine with beneficial and negative outcomes in the management of...

Ketamine Self-Medication in a Patient with Autism Spectrum Disorder and Comorbid Therapy-Resistant Depression

Psychiatry and Clinical Psychopharmacology September 1, 2022 Mihriban Heval Özgen, W. van den Brink

In this case report, we present an adult male patient with autism spectrum disorder and a comorbid (treatment-resistant) mood disorder with suicidality. He has been treated with numerous psychopharmaceuticals, most recently risperidone and valproic acid. He has been hospitalized several times and has attempted suicide. He displayed limited social functioning, repetitive behaviors, sensory...

Ketamine With Psychotherapy for the Treatment of Depression

Psychiatric Annals September 1, 2022 Fernando Espí Forcén, Maren Nyer

To date, ketamine is the only prescribable psychedelic medicine in the United States. Ketamine is also one of the most promising drugs for the treatment of depression. In the current paradigm of care, most ketamine clinics in the United States treat patients with mood disorders with ketamine and its derivatives alone without psychotherapy. The purpose of this article is to review the most...

Depression and antidepressant effects of ketamine and its metabolites: The pivotal role of gut microbiota.

Neuropharmacology September 1, 2022 Hao-Ming Hua, Chao Huang, Hanyu Liu et al. 35 citations

The discovery of the robust antidepressant actions of ketamine is regarded as one of the greatest advancements in depression treatment in the past 60 years. Recent findings have provided strong evidence for the presence of bidirectional communication networks between the gastrointestinal tract and the brain in depression. Moreover, increasing evidence supports the antidepressant role of...

Mapping consent practices for outpatient psychiatric use of ketamine.

Journal of Affective Disorders September 1, 2022 David S. Mathai, Scott M Lee, Victoria Mora et al. 16 citations

Given increasing community-based and off-label use of ketamine for psychiatric indications, we examined current informed consent processes from a convenience sample of outpatient ketamine clinics to identify areas of congruence with current evidence and opportunities for growth. Using a rubric developed from existing practice guidelines, we conducted an exploratory analysis of informed consent...

Anterior default mode network and posterior insular connectivity is predictive of depressive symptom reduction following serial ketamine infusion.

Psychological Medicine September 1, 2022 Benjamin Wade, Joana R Loureiro, Ashish K Sahib et al. 18 citations

Ketamine is a rapidly-acting antidepressant treatment with robust response rates. Previous studies have reported that serial ketamine therapy modulates resting state functional connectivity in several large-scale networks, though it remains unknown whether variations in brain structure, function, and connectivity impact subsequent treatment success. We used a data-driven approach to determine...

Experimenters’ sex modulates mouse behaviors and neural responses to ketamine via corticotropin releasing factor

Nature Neuroscience August 30, 2022 Polymnia Georgiou, Panos Zanos, Ta-Chung M. Mou et al.

We show that the sex of human experimenters affects mouse behaviors and responses following administration of the rapid-acting antidepressant ketamine and its bioactive metabolite (2R,6R)-hydroxynorketamine. Mice showed aversion to the scent of male experimenters, preference for the scent of female experimenters and increased stress susceptibility when handled by male experimenters. This...

Efficacy of ketamine intervention to decrease alcohol use, cravings, and withdrawal symptoms in adults with problematic alcohol use or alcohol use disorder: A systematic review and comprehensive analysis of mechanism of actions.

Drug and Alcohol Dependence August 19, 2022 Nicolas Garel, Christina Mcanulty, Kyle T. Greenway et al. 33 citations

BACKGROUND: Alcohol use disorder is highly prevalent and has important economical, societal, psychiatric, and medical consequences. All currently approved therapeutic approaches targeting alcohol dependence have relatively modest effects and high relapse rates. Recent evidence suggests that ketamine may be an effective intervention to treat alcohol use disorder and alcoholic withdrawal. This...

BDNF Alterations in Brain Areas and the Neurocircuitry Involved in the Antidepressant Effects of Ketamine in Animal Models, Suggest the Existence of a Primary Circuit of Depression

Journal of Integrative Neuroscience August 16, 2022 Ezio Carboni, Anna R. Carta 15 citations

Major depressive disorder is one of the primary causes of disability and disease worldwide. The therapy of depression is prevalently based on monoamine reuptake blockers; consequently, investigations aimed to clarify the aetiology of depression have mostly looked at brain areas innervated by monamines and brain circuitry involved in inputs and outputs of these areas. The recent approval of...
