OBJECTIVE Previous studies have found an association between klotho, an anti-aging hormone, and major depressive disorder. However, whether low-dose ketamine infusion alters klotho levels among patients with treatment-resistant depression (TRD) remains unknown. METHODS In total, 48 patients with TRD and strong suicidal ideation were randomly assigned to a single 0.5 mg/kg ketamine or 0.045...

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...

Abstract Background The benefits of low-dose ketamine for patients with treatment-resistant depression (TRD) and prominent suicidal ideation require further investigation. The effects of treatment refractoriness, the duration of the current depressive episode, and the number of prior antidepressant failures on ketamine efficacy also require clarification. Methods We recruited 84 outpatients...

BACKGROUND Whether cortical excitation and inhibition functions differ between patients with treatment-resistant depression (TRD) and strong suicidal ideation (SI) and healthy subjects and whether 0.5 mg/kg ketamine infusion can modulate cortical excitation and inhibition functions among patients with TRD-SI remain unclear. METHODS A total of 29 patients with TRD-SI and 35 age- and sex-matched...

BACKGROUND This posthoc analysis compared the antidepressant and antisuicidal effects of low-dose ketamine infusion with those of repetitive transcranial magnetic stimulation (rTMS) on treatment-resistant depression (TRD). METHODS In the ketamine infusion trial, 48 patients with TRD were randomized to receive a single infusion of 0.5 mg/kg ketamine or normal saline. In the rTMS trial, 105...
