Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Major depressive disorder (MDD) is one of the most common psychiatric disorders, characterized by extremely high prevalence, relapse rate and therapeutic resistance. Treatment with ketamine and its enantiomer esketamine is the next step towards the successful treatment and understanding of depression that is resistant to treatment with standard antidepressants. The proposed study will include approximately 50 patients with MDD and 50 healthy control subjects of both sexes. Using untargeted metabolomic approach, we plan to detect changes in biochemical pathways related to the diagnosis of treatment-resistant MDD and changes related to the mechanism of action of esketamine. The proposed research will contribute to further understanding of the mechanism of action of esketamine in patients with MDD. Metabolic changes will be associated with improvements in specific domains of depressive symptoms and symptom severity in subjects with treatment-resistant major depressive disorder.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* for healthy control participants: 18-70 years, both sexes, without psychiatric drugs
* for patients: from 18- 70 years, both sexes, failed treatment attempts with at least two antidepressants of the appropriate dose and duration.

Exclusion Criteria

* for patients: treatment with tryptophan, St. John's wort, and/or opioid analgesics in the last month, daily intake of benzodiazepines;
* for all participants: presence of psychotic symptoms, alcohol and/or drug addiction, disorder seizures, eating disorder, dementia and other neurodegenerative diseases, epilepsy, intellectual disabilities, severe somatic diseases (including insufficiently controlled arterial hypertension, diabetes and thyroid diseases), active psychotherapeutic treatment (except supportive psychotherapy, which is an integral part of every psychiatric treatment and will be the same in all groups of respondents).

Participants will be excluded if they follow a weight loss diet or take weight loss medication, are pregnant or breastfeeding.
