Abstract

Objective: Hypertension and hyperlipidemia are two major risk factors for cardiovascular disease 
in continuous ambulatory peritoneal dialysis (CAPD) patients. This study was designed to investigate 
the effect of omega-3 fatty acids on blood pressure (BP) and serum lipids in CAPD patients.
Methods: This study was a randomized double‑blind clinical trial in which 90 CAPD patients 
were randomly assigned to either the omega‑3 or the placebo group. Patients in omega‑3 
group received 3 g/day omega‑3 for 8 weeks, whereas patients in the control group received 
placebo. At baseline and at the end of 8 weeks, the patients’ BP was controlled, and serum 
biochemistry was measured.
Findings: Mean systolic BP decreased (–22.2 ± 14.2 mmHg) in the omega‑3 group at the end 
of the study while in the placebo group increased (+0.5 ± 30.2 mmHg) (P < 0.0001). Mean 
diastolic BP of the omega‑3 group decreased more (–11.95 ± 11.9 mmHg) comparing with 
the placebo group (–1.1 ± 17.3 mmHg) (P = 0.001). There were no significant differences 
between the two groups in mean changes in serum triglyceride, and total, high‑density 
lipoprotein, and low‑density lipoprotein cholesterol.
Conclusion: The results of this study indicate that omega‑3 reduced BP significantly but 
had no effect on lipid profile in our CAPD patients.
