Changes in triglyceride levels in ultra-high risk for psychosis individuals treated with omega-3 fatty acids.

ABSTRACT

AIM: The aim of this analysis was to assess changes in lipid parameters, specifically in triglyceride (TG) levels, in a population at ultra-high risk (UHR) for psychosis treated with ω-3 polyunsaturated fatty acids (PUFAs) versus placebo. METHODS: Data were derived from a randomized, double-blind, placebo-controlled trial conducted at an early psychosis unit. Eighty-one individuals, aged 13-25 years, at UHR for psychosis participated in a 12-week intervention trial of 1.2 g/day of ω-3 PUFAs (n = 41) versus placebo (n = 40). Lipid and C-reactive protein levels were collected at baseline and after 12 weeks. RESULTS: Between-group comparisons showed no significant difference in TG levels after the intervention. However, in individuals with baseline TG levels above 150 mg dL-1 there was a significant mean TG reduction of 67.29 (SD 42.54; P = 0.006) in the ω-3 group (n = 7). CONCLUSION: In this sample of UHR individuals, a 12-week intervention with ω-3 PUFAs was effective in reducing previously elevated TG levels. This might introduce the possibility of altering the lipid profile and thus the risk of cardiovascular morbidity of UHR individuals.
