Children with Chronic Kidney Disease (CKD) are at very high risk for cardiovascular morbidity and mortality. Hyper-lipidemia, a traditional risk factor for Cardiovascular Disease (CVD), occurs early in the progression of kidney failure; timely identification and intervention is prudent. Currently, there is no known effective therapy for hypertriglyceridemia, the most common lipid abnormality. n-3FA, in doses ranging from 2-6 g/day have effectively lowered elevated triglyceride (TG) levels by 20-50% in a variety of adult populations; however, their use in children with CKD has not been tested in a randomized controlled fashion. This study will provide important information on the safety, efficacy and tolerance of n-3FA in lowering elevated TG levels in children and adolescents with CKD.

Arms Assigned Interventions
Experimental: Supplement Dietary Supplement: n-3 Fatty Acid supplement

Children will be prescribed 1600-1800 mg EPA + DHA per m2 Body Surface Area, to a maximum of the upper limit of the age-appropriate range recommended by Health Canada.

Each n-3FA gel capsule (1000 mg) will contain 400 mg EPA and 200 mg DHA derived from the oil of wild anchovies and sardines. A smaller gel capsule (500 mg; 200 mg EPA + 100 mg DHA) will be available for children unable to swallow large solid medication and a flavored liquid formulation, containing a similar proportion of EPA + DHA (2200 mg fish oil concentrate from anchovies and sardines, 750 mg EPA, 375 mg DHA per ½ teaspoon), will be available for use in toddlers and older children unable to swallow gel capsules.

Placebo Comparator: Control Dietary Supplement: Placebo
The placebo, identical in opaque appearance and citrus-flavored taste, will contain a 50:50 blend of soybean and corn oil for both gel capsule (2 sizes) and liquid formulations.

Detailed Description:

Following counseling on dietary and lifestyle changes to lower triglyceride levels, and a period of applying these modifications, children will be assigned in a random fashion to take either fish oil supplements or a placebo (soybean/corn oil) for 8 weeks. After this 8-week treatment period, children will not take a supplement for 4 weeks and then will be assigned the alternate product (fish oil or placebo) for another 8 weeks. Our main interest is to see whether there is a larger decrease in triglyceride levels after taking the fish oil supplement compared to the placebo.

The primary objective of this study is to determine whether omega-3 fatty acid supplements, given at therapeutic dosages over an 8-week period, significantly decrease elevated serum TG in children with CKD;

The secondary objectives of this study are:

i. To evaluate the effect of n-3 fatty acid supplements on total-, LDL-, and HDL-cholesterol;

ii. To determine whether n-3 fatty acid supplements are well tolerated by our study participants; and

iii. To test whether TG-lowering effects are sustained up to 4 weeks after stopping supplements.
