Abstract

Deficiency in long-chain omega-3 LCn − 3 fatty acids, eicosapentaenoic acid EPA, 20:5n − 3 and docosahexaenoic acid DHA, 22:6n − 3, has been implicated in the pathoetiology of cardiovascular disease, a primary cause of excess premature mortality in patients with schizophrenia SZ. In the present study, we determined erythrocyte EPA + DHA levels in adult medication-free patients SZ and age-matched healthy controls . Erythrocyte EPA + DHA composition exhibited by SZ patients 3.5% was significantly lower than healthy controls 4.5%, −22%, . The majority of SZ patients 72% exhibited EPA+DHA levels ≤4.0% compared with 37% of controls Chi-square, . In contrast, the omega-6 fatty acid arachidonic acid AA, 20:4 +9%, and the AA:EPA + DHA ratio +28%, were significantly greater in SZ patients. Linoleic acid 18:2 was significantly lower −12%, and the erythrocyte 20:3-18:2 ratio an index of delta6-desaturase activity was significantly elevated in SZ patients. Compared with same-gender controls, EPA + DHA composition was significantly lower in male −19%, but not female −13%, SZ patients, whereas the 20:3-18:2 ratio was significantly elevated in both male +22%, and female +22%, SZ patients. These results suggest that the majority of SZ patients exhibit low LCn − 3 fatty acid levels which may place them at increased risk for cardiovascular morbidity and mortality.
