Omega-3 supplementation effects on cardiovascular risk and inflammatory profile in chronic kidney disease patients in hemodialysis treatment: An intervention study
Abstract
Background and aims: Chronic Kidney Disease (CKD) is characterized by slow, progressive, and irreversible kidney function loss and the disease itself and hemodialysis treatment can predispose an inflammatory state that increased cardiovascular complications, being one of major mortality causes in kidney patients. The study purpose was to evaluate nutritional profile and impacts of w-3 fatty acid supplementation on inflammatory parameters and cardiovascular events risk in patients with CKD undergoing hemodialysis treatment.
Methods: Non-randomized clinical trial, patients with CKD were randomly grouped into a control (n = 29) and supplemented (n = 30) group. Supplemented group patients were instructed to consume two w-3 capsules a day (2g/day) for 8 weeks for further analysis of pre- and post-supplementation C-reactive protein (CRP) and other blood parameters. To nutritional status assessment, anthropometric and bioelectrical impedance data were measured, carried out close to supplementation start.
Results: 59 patients were evaluated, 49.1% (n = 29) were overweight and 70.7% (n = 41) had high percentage of body fat. Comparing control versus supplemented groups after supplementation serum CRP levels have reduced, no differences were observed (p = 0.716) nevertheless there was reduction in cardiovascular events risk according to C-reactive protein classification (p = 0.004). Ferritin levels have improved in all groups. Changes in the levels of other biochemical markers…
How strong is the evidence?
Evidence Hub reads this as a clinical 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: 59 participants or records.
