Plain English Summary

Background and study aims
Depressive disorder (DD) has become a common recurrent disease among adolescents and the treatment of adolescent DD is inadequate and less effective. The rate of receiving treatment in adolescent depression is lower than that in adults, and antidepressants and psychotherapy that are effective in the treatment of depression in adults have a limited effect in adolescents. Therefore, there is an urgent need for safer and more effective treatments for adolescent depression. Several clinical trials have shown that the use of polyunsaturated fatty acids (PUFAs) is a safe and effective adjuvant therapy in adult DD but studies are very limited in adolescents. The aim of this study is to evaluate the effect of ω-3 PUFA extra supplementation in adolescent depression, and explore whether the niacin skin flushing response relates to depressive symptoms.

Who can participate?
Adolescents aged 14-25 years with depression who are registered at the Fourth People's Hospital of Wuhu

What does the study involve?
Patients are randomly allocated to one of two groups. Those in the first group only take the antidepressant paroxetine every day for 12 weeks. Those in the second group take three capsules of ω-3 PUFA rich fish oil per day for 12 weeks in addition to paroxetine treatment. The niacin skin flushing response and the severity of depressive symptoms, cognition, and memory conditions are assessed by trained psychiatrists before treatment and at weeks 4, 8, and 12. Blood samples are taken at weeks 0 and 12.

What are the possible benefits and risks of participating?
Participants who receive the PUFA may benefit from a reduction of their depressive symptoms. There are no known risks involved with participating.

Where is the study run from?
1. Shanghai Jiao Tong University (China)
2. The Fourth People's Hospital of Wuhu (China)

When is the study starting and how long is it expected to run for?
April 2020 to December 2025

Who is funding the study?
1. Health Commission of Anhui Province (China)
2. Natural Science Foundation of Shanghai (China)
3. Shanghai Jiao Tong University (China)

Study hypothesisThe aim of this study is to evaluate the therapeutic effects of ω-3 polyunsaturated fatty acid (PUFA) supplementation combined with paroxetine in adolescent patients with depression, and explore whether niacin skin flushing response is related to depressive symptoms.
Ethics approval(s)Approved 21/04/2020, Ethical Committee of the Fourth People's Hospital of Wuhu (No.1, Wuxiashan East Road, Wuhu City, Anhui Province, China; +86 (0)553 3028569; xiazhongxiansheng@163.com), ref: not applicable
ConditionDepressive disorder
InterventionPatients are randomly assigned to take paroxetine alone (paroxetine group, n = 37) and ω-3 PUFA rich fish oil in addition to paroxetine (ω-3 PUFA + paroxetine group, n = 34) for 12 weeks, according to a computer-generated random sequence using block randomisation with random block sizes. The randomisation is performed by the independent statistician. Patients are enrolled and assigned sequentially to adjuvant interventions by the physician. The allocation sequence is not available to any member of the research team until the databases had been completed and locked.

The dose of paroxetine is 20 mg per day and ω-3 PUFA rich fish oil is three capsules per day (providing 2700 mg of total ω-3 PUFA; 1941 mg EPA and 759 mg DHA, EPA:DHA ratio = 2.56:1).

The severity of depressive symptoms, cognition and memory conditions are assessed by trained psychiatrists using the Montgomery-Asberg Depression Rating Scale (MADRS), Montreal Cognitive Assessment (MoCA) and Wisconsin Card Sorting Test (WCST), and Wechsler Memory Scale (WMS), respectively, before therapy (baseline), and at weeks 4, 8, and 12. Niacin skin flushing response is tested at the week 0, 4, 8 and 12. Blood samples are taken at weeks 0 and 12.
