Abstract
Background: Recent studies reported that omega-3 fatty acids may improve renal function in patients with chronic kidney disease (CKD). The aim of the present study was to assess the effect of omega-3 supplements on renal function indices in patients with CKD undergoing hemodialysis.
Methods: This randomized controlled clinical trial was carried out on 120 CKD patients who were undergoing hemodialysis treatment in Rasht, Iran. The intervention group (n = 60) received 3 capsules of 1000 mg omega-3 fatty acid supplement capsules daily for 2 months. The control group (n = 60) received 3 placebo capsules containing 1000 mg of MCT. Renal function indicators included blood urea nitrogen (BUN), creatinine (Cr), sodium (Na), potassium (K), calcium (Ca), and phosphorus (P) were measured at baseline and after the intervention.
Results: Omega-3 supplementation significantly improved BUN (68.26 ± 2.97 to 56.59 ± 2.14, P = .03) and Cr levels (8.94 ± 0.29 to 7.58 ± 0.41, P < .01) after adjustment for age, gender, body mass index (BMI), smoking, diet, and underlying diseases including diabetes and hypertension. However, no significant effect was found on serum levels of Na, K, Ca, and P.
Conclusion: According to the present study, giving omega-3 supplementation to patients with CKD undergoing HD may enhanced their renal function. Additional research is required to verify these results.
期刊介绍:
Nutrition and Metabolic Insights is a peer-reviewed, open-access online journal focusing on all aspects of nutrition and metabolism. This encompasses nutrition, including the biochemistry of metabolism, exercise and associated physical processes and also includes clinical articles that relate to metabolism, such as obesity, lipidemias and diabetes. It includes research at the molecular, cellular and organismal levels. This journal welcomes new manuscripts for peer review on the following topics: Nutrition, including the biochemistry of metabolism, Exercise and associated physical processes, Clinical articles that relate to metabolism, such as obesity, lipidemias and diabetes, Research at the molecular, cellular and organismal levels, Other areas of interest include gene-nutrient interactions, the effects of hormones, models of metabolic function, macronutrient interactions, outcomes of changes in diet, and pathophysiology.
