Long-term remission following esketamine nasal spray sessions in a patient with severe and highly treatment-resistant depression: a single-case report.

International Clinical Psychopharmacology July 11, 2023 Lucas Arrighi, Eloïse Maakaron, Théo Korchia et al.

About 30% of patients with major depressive disorder have treatment-resistant depression (TRD). Recently, intranasal esketamine was approved as a treatment option after the failure of two antidepressant trials. We report a patient with multiresistant depression that was successfully and safely treated with esketamine nasal spray. This 31-year-old inpatient with severe, chronic, and multi-TRD...

Central nervous system-related safety and tolerability of add-on ketamine to standard of care treatment in treatment-resistant psychotic depression in patients with major depressive disorder and bipolar disorder

Frontiers in Neuroscience July 11, 2023 Maria Gałuszko‐węgielnik, Katarzyna Jakuszkowiak‐wojten, Mariusz S. Wiglusz et al. 8 citations

Background: Psychotic treatment-resistant depression represents a complex and challenging form of mood disorder in clinical practice. Despite its severity, psychotic depression is frequently underdiagnosed and inadequately treated. Ketamine has demonstrated rapid and potent antidepressant effects in clinical studies, while exhibiting a favorable safety and tolerability profile. Although there...

Differential effectiveness between Ketamine and Esketamine: the predictive role of dissociative features. A treatment-resistant depression case.

International Clinical Psychopharmacology July 7, 2023 Nicola Ragone, Barbara Barbini, Carolina Passani et al.

More than 10 years ago, the discovery of the antidepressant effects of Ketamine opened the opportunity to develop a novel class of antidepressants. Ketamine induces dissociative symptoms as a major side effect. This rapid-acting antidepressant is available as an endovenous racemic compound and as an intranasal S-enantiomer: Esketamine; which is four-fold more potent for the NMDA receptor. Here...

Ketamine alleviates fear memory and spatial cognition deficits in a PTSD rat model via the BDNF signaling pathway of the hippocampus and amygdala

Research Square July 3, 2023 Yue Teng, JiaYao Niu, Yang Liu et al. preprint

Abstract Background Post-traumatic stress disorder (PTSD) is associated with traumatic stress experiences. This condition can be accompanied by learning and cognitive deficits. Studies have demonstrated that ketamine can rapidly and significantly alleviate symptoms in patients with chronic PTSD. Nonetheless, the effects of ketamine on neurocognitive impairment and its mechanism of action in...

Predicting non-response to ketamine for depression: a symptom-level analysis of real-world data

medRxiv Preprint Server July 3, 2023 Eric A. Miller, Houtan Totonchi Afshar, Jyoti Mishra et al. preprint

Background Ketamine helps some patients with treatment resistant depression (TRD), but reliable methods for predicting which patients will, or will not, respond to treatment are lacking.

Reduction in Cognitive Symptoms Following Intranasal Esketamine Administration in Patients With Chronic Treatment-resistant Depression: A 12-Week Case Series.

Journal of Psychiatric Practice July 1, 2023 Maria Pepe, Giovanni Bartolucci, Ilaria Marcelli et al.

Background: Cognitive symptoms are a core feature of depressive disorders, interfere with full functional recovery and are prominent in patients with treatment-resistant depression (TRD), particularly in severe chronic cases. Intranasal (IN) esketamine was recently approved for the treatment of TRD; however, its effects on cognitive symptoms are unclear. In this article, we describe cognitive...

Ketamine for Treatment of Posttraumatic Stress Disorder: State of the Field.

FOCUS: The Journal of Lifelong Learning in Psychiatry July 2023 Rachel Fremont, Oneysha Brown, Adriana Feder et al.

Posttraumatic stress disorder (PTSD) is a chronic and debilitating condition. Although several psychotherapeutic and pharmacological treatments are recommended for PTSD, many individuals do not respond to treatment or respond only partially, highlighting a critical need for additional treatments. Ketamine has the potential to address this therapeutic need. This review discusses how ketamine...

Effects of low-dose ketamine infusion on vascular endothelial growth factor and matrix metalloproteinase-9 among patients with treatment-resistant depression and suicidal ideation.

Journal of Psychiatric Research July 1, 2023 Mu-Hong Chen, Wei-Chen Lin, Cheng-Ta Li et al. 8 citations

BACKGROUND Evidence indicates that vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) influence the pathophysiology of depression. However, whether low-dose ketamine regulates VEGF and MMP-9 levels and whether changes in VEGF and MMP-9 levels are associated with the antidepressant and antisuicidal effects of ketamine remained unclear. METHODS Forty-eight patients...

Change in patient‐centered outcomes of psychological well‐being, sleep, and suicidality following treatment with intravenous ketamine for late‐life treatment‐resistant depression

International Journal of Geriatric Psychiatry July 1, 2023 Benjamin Vanderschelden, M. A. Gebara, H. Oughli et al. 13 citations

To examine whether psychological well‐being, sleep, and suicidality improved with treatment with intravenous (IV) ketamine for late‐life treatment‐resistant depression (TRD).

Case report: Identification of AP-238 and 2-fluorodeschloroketamine in internet available powder samples sold as bucinnazine.

Forensic Science International July 1, 2023 Karissa N Resnik, Kala N Babb, Lori W Bekenstein et al. 2 citations

Novel synthetic opioids (NSOs) are a class of opioid agonists that include analogs of fentanyl and structurally distinct non-fentanyl compounds normally used as standalone products, heroin adulterants, or constituents of counterfeit pain pills. Most NSOs are not currently scheduled in the U.S., are predominantly illegally synthesized, and sold on the Darknet. Among them, the cinnamylpiperazine...
