Brief Summary

Mexico, prevalence reported for major depressive disorder (MDD) is of 7.2%. It is currently in the top 5 causes of disability worldwide. One third of patients will not achieve remission after two treatments, being classified as treatment-resistant. In a neurochemical level, evidence shows dysregulation of the excitatory neurotransmitter Glutamate in patients with MDD. Chronic stress has been related to this dysregulation. Ketamine, has shown to regulate glutamatergic neurotransmission, and specially promote the release and production of neurotrophic factors key in the causes of MDD inhibited by glutamate dysregulation), and allow restoration of areas affected. Clinical studies of ketamine in MDD have shown robust, durable , and rapid effects (during the first 4-24 hours), allowing a great opportunity for patients who do not achieve benefits from antidepressants or patients with suicidal ideation . These results have been reported in metaanalysis. To our knowledge, there are no studies using Magnetic Resonance Spectroscopy, in areas related to MDD, after a series of ketamine administrations, which we think may show changes after this chronic administration and explain its antidepressant properties. Goals: Provide clinical evidence of responseas well as a neurological basis or biomarker of response to a series of ketamine infusions.

Outcome Measures

Primary Outcomes (4)

  • Depression Severity Hamilton Depression Rating Scale

    Depression Severity (10 - 13 mild; 14-17 mild to moderate; \>17 moderate to severe). Higher values represent a worse severity, but not necessarily outcome.

    4, 24, 72 hours, weekly up to 12 weeks or until relapse (Change from baseline to each measure)

  • Glutamate

    Glutamate levels in the pgACC basal and after the last intervention with ketamine or placebo

    Basal, 10 minutes during intervention, 24 hours after, 4 weeks after (Change from baseline to each measure)

  • GABA

    GABA levels in the pgACC basal and after the last intervention with ketamine or placebo

    Basal, 10 minutes during intervention, 24 hours after, 4 weeks after (Change from baseline to each measure)

  • Depression Severity Montgomery-Asberg Depression Rating Scale)

    Depression Severity (9-17 = mild, 18-34 = moderate, and ≥ 35 = severe)

    4, 24, 72 hours, weekly up to 12 weeks or until relapse (Change from baseline to each measure). Higher values represent a worse severity, but not necessarily outcome.
