Maintenance of antidepressant and antisuicidal effects by D-cycloserine among patients with treatment-resistant depression who responded to low-dose ketamine infusion: a double-blind randomized placebo-control study.

ABSTRACT: Increasing evidence supports a rapid antidepressant and antisuicidal effect of a single subanesthetic dose of ketamine infusion for treatment-resistant depression (TRD). Maintaining the initial clinical response after ketamine infusion in TRD is a crucial next-step challenge. D-cycloserine (DCS), a partial agonist of the glycine co-agonist of the N-methyl-D-aspartate (NMDA) glutamate receptor, is potentially effective as a depression augmentation treatment. However, whether DCS maintains the antidepressant and antisuicidal effects of ketamine infusion remains unknown. In all, 32 patients with TRD (17 with major depression and 15 with bipolar depression) who responded to ketamine infusion with an average 17-item Hamilton Depression Rating Scale (HAMD) score of 9.47 ± 4.11 at baseline were r
