Ketamine-Assisted Group Psychotherapy for Frontline Healthcare Workers with COVID-19-Related Burnout and PTSD: A Case Series of Effectiveness/Safety for 10 Participants.

Journal of Psychoactive Drugs 2024 Reid Robison, Madeline Brendle, Claire Moore et al.

This study reports on 10 frontline healthcare workers, employed during the COVID-19 pandemic and experiencing symptoms of burnout and PTSD, treated with group ketamine-assisted psychotherapy (KAP) in a private outpatient clinic setting. Participants attended 6 sessions once weekly. These included 1 preparation session, 3 ketamine sessions (2 sublingual, 1 intramuscular), 2 integration sessions....

Hypersomnia as a predictor of response to intravenous ketamine/intranasal esketamine in treatment resistant depression.

Journal of Affective Disorders 2024 Liliana Patarroyo-Rodriguez, Vanessa M. Pazdernik, Jennifer L. Vande Voort et al. 12 citations

BACKGROUND Sleep disturbances are highly prevalent in depressive episodes and are linked to higher mood severity and suicidal behaviors. Slow wave sleep (SWS) and REM sleep are compromised in depression. Current evidence suggests that rapid antidepressant effects of intravenous (IV) ketamine in patients with treatment-resistant depression (TRD) is mediated by its effects on SWS and REM sleep....

Therapeutic Protocols Using Ketamine and Esketamine for Depressive Disorders: A Systematic Review.

Journal of Psychoactive Drugs 2024 Julia M.k. Freind, Fernando R. Beserra, Bruno S Menezes et al. 9 citations

Depression is one of the most prevalent mental health disorders globally, causing severe emotional suffering, reducing life expectancy and increasing the risk of suicide. Recently, the use of dissociative psychedelic substances such as ketamine and esketamine for depressive disorders has expanded treatment options. We sought to analyze, through a systematic review, the existing protocols for...

Behavioral sensitization and tolerance induced by repeated treatment with ketamine enantiomers in male Wistar rats.

PLoS One 2024 Kristian Elersič, Anamarija Banjac, Marko Živin et al. 6 citations

Ketamine has gained significant attention as a fast-acting antidepressant. However, ketamine is also associated with undesirable side effects. In our preclinical study, we explored the behavioral effects of ketamine enantiomers at subanesthetic doses. During repeated intermittent treatment, we examined locomotor stimulation and sensitization, ataxia, and expression of natural behaviors...

Anhedonia and depression severity measures during ketamine administration in treatment-resistant depression.

Frontiers in Psychiatry 2024 Aleksander Kwaśny, Wiesław Jerzy Cubała, Adam Włodarczyk 7 citations

Anhedonia is a core symptom of depression characterized by a diminished ability to experience pleasure. Currently available treatments for depression often fall short in adequately addressing anhedonia that often presents as a chronic and debilitating symptom. Ketamine is known to possess antianhedonic properties. This post-hoc analysis of a naturalistic observational study of...

Patient-reported outcomes on sleep quality and circadian rhythm during treatment with intravenous ketamine for treatment-resistant depression.

Therapeutic Advances in Psychopharmacology 2024 Raymond Yan, Tyler Marshall, Atul Khullar et al. 11 citations

Intravenous (IV) ketamine is a rapid acting antidepressant used primarily for treatment-resistant depression (TRD). It has been suggested that IV ketamine's rapid antidepressant effects may be partially mediated via improved sleep and changes to the circadian rhythm. This study explores IV ketamine's association with changes in patient-reported sleep quality and circadian rhythm in an adult...

Ketamine for depressive symptoms: A retrospective chart review of a private ketamine clinic.

South African Journal of Psychiatry 2024 Vidette M Juby, Saaeda Paruk, Mitsuaki Tomita et al. 3 citations

There is currently no published evidence demonstrating the effectiveness and safety of subanaesthetic doses of ketamine, when administered intravenously as an adjunct treatment for depressive symptoms, in a real world setting in South Africa. This retrospective chart review reports the clinical response (change in Patient Health Questionnaire - 7 score) to an initial infusion series of ketamine...

Case report: Adult with bipolar disorder and autism treated with ketamine assisted psychotherapy.

Frontiers in Psychiatry 2024 Christopher P Harris, Becky Jones, Kathryn Walker et al. 4 citations

Evidence has increased in recent years regarding the potential for ketamine to serve as a novel treatment option for a range of conditions, particularly depression (unipolar and bipolar). However, research regarding ketamine as a potential therapeutic for Autism Spectrum Disorder (ASD) is lacking, despite high overlap with bipolar depression and theoretical foundations for its use. A...

Hype or hope? High placebo response in major depression treatment with ketamine and esketamine: a systematic review and meta-analysis.

Frontiers in Psychiatry 2024 Alexandros Matsingos, Marcel Wilhelm, Laila Noor et al. 18 citations

Ketamine and esketamine offer a novel approach in the pharmacological treatment of major depressive disorder (MDD). This meta-analysis aimed to investigate the placebo response in double-blind, randomized controlled studies (RCTs) on patients with MDD receiving ketamine or esketamine. For this systematic review and meta-analysis Medline (PubMed), Cochrane Central Register of Controlled Trials...

The effect of low dose intra-articular S(+) ketamine on osteoarthritis in rats: an experimental study.

Brazilian journal of anesthesiology (Elsevier) 2024 Eugênio Dos Santos Neto, Pedro Paulo de Alcantara Pedro, Maria do Socorro de Sousa Cartágenes et al. 1 citation

This study aimed to investigate the analgesic impact of S(+)-ketamine on pain behavior and synovial inflammation in an osteoarthritis (OA) model. Animals were grouped as follows: OA-Saline (n = 24) and OA-Ketamine (n = 24), OA induced via intra-articular sodium monoiodoacetate (MIA); a Non-OA group (n = 24) served as the control. On the 7th day post OA induction, animals received either saline...
