A randomized clinical trial of high eicosapentaenoic acid omega-3 fatty acids and inositol as monotherapy and in combination in the treatment of pediatric bipolar spectrum disorders: a pilot study
Abstract
OBJECTIVE: We conducted a 12-week, randomized, double-blind, controlled clinical trial to evaluate the effectiveness and tolerability of high eicosapentaenoic acid (EPA)/docosahexaenoic acid (DHA) omega-3 fatty acids and inositol as monotherapy and in combination in children with bipolar spectrum disorders.
METHOD: Participants were children 5-12 years of age meeting DSM-IV diagnostic criteria for bipolar spectrum disorders (bipolar I or II disorder or bipolar disorder not otherwise specified [NOS]) and displaying mixed, manic, or hypomanic symptoms. Subjects with severe illness were excluded. Subjects were randomized to 1 of 3 treatment arms: inositol plus placebo, omega-3 fatty acids plus placebo, and the combined active treatment of omega-3 fatty acids plus inositol. Data were collected from February 2012 to November 2013.
RESULTS: Twenty-four subjects were exposed to treatment (≥ 1 week of study completed) (inositol [n = 7], omega-3 fatty acids [n = 7], and omega-3 fatty acids plus inositol [n =10]). Fifty-four percent of the subjects completed the study. Subjects randomized to the omega-3 fatty acids plus inositol arm had the largest score decrease comparing improvement from baseline to end point with respect to the Young Mania Rating Scale (P < .05). Similar results were found for the Children's Depression Rating Scale (P < .05) and the Brief Psychiatric Rating Scale (P <.05).
CONCLUSION: Results of this pilot randomized, double-blind, controlled trial suggest that the…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 10 participants or records.
