Brief Summary
In this study, the investigators will stratify depressed subjects a priori based on CRP levels to test the hypothesis that eicosapentaenoic (EPA) would be more efficacious to treat depression in subjects with high CRP levels compared to subjects with low CRP levels. Depressed subjects, with ongoing stabilized antidepressive treatment who remain clinically depressed, will be enrolled in an "Inflammation group" or in a "Non-inflammation group" depending on baseline levels of CRP. Subjects in both groups will receive EPA enriched omega-3 fatty acids for 8 weeks, added to their pre-stabilized antidepressant medication.

Non-inflammation group
ACTIVE COMPARATORSubjects with CRP\<3, will receive eicosapentaenoic acid enriched omega-3 fatty acids, 2 g/day, for 8 weeks, added to their pre-stabilized antidepressant medication
Interventions
Eicosapentaenoic acid enriched omega-3 fatty acids, 2 g/day, added to pre-stabilized antidepressant medication
Eligibility Criteria
You may qualify if:
- Male/female, aged 18-80.
- Fulfilling the DSM criteria for a current depressive episode, unipolar (symptom duration\> 4 weeks) as determined by the study physician
- HAM-D-17 score ≥ 15 (Rapaport, Nierenberg et al. 2016)
- A Clinical Global Impression Severity Score ≥ 3 (Rapaport, Nierenberg et al. 2016)
- All subjects should be stable on antidepressants or mood stabilizers ≥6 weeks.
- Willing to not significantly modify their diet from the time they sign consent through the end of study participation.
You may not qualify if:
- Serious or unstable medical illness that in the investigator's opinion could compromise response to treatment or interpretation of study results. Examples: Malignancy not in remission for at least 1 year, Active autoimmune disorder or inflammatory bowel disease, Insulin-dependent diabetes mellitus.
- Known or suspected allergy to the study compounds.
- Ongoing infection.
- Ongoing pregnancy or breast-feeding
- A diagnosis of psychotic disorder, bipolar disorder, mental retardation dementia, or individual whom, due to other causes, lack the ability to make an informed decision.
- Ongoing ECT.
- Concomitant use of anticoagulants or known bleeding disorder.
- Patients who, in the investigator's judgment, pose a current, serious suicidal or homicidal risk.
- A diagnosis for any Substance Use Disorder (except nicotine or caffeine) in the 3 months prior to the screening visit.
- Any medications (within 1 week of baseline or during the trial) that might confound the biomarker findings, including: Regular ingestion of NSAIDs or COX-2 inhibitors, or any use of oral steroids, immunosuppressants, interferon, chemotherapy (Patients will be instructed not to take an NSAID, COX-2 inhibitor or Aspirin in the 24 hours prior to a biomarker assessment visit).
- Patients who have taken supplements with omega-3 fatty acids for more than three consecutive days in the preceding month.
- Within 4 weeks of starting psychotherapy or planning to start psychotherapy during the study
- Active participation in other clinical studies with ongoing study visits
