OBJECTIVE: We studied the effect of a diet supplementation with fish oil in insulin-dependent diabetic patients with nephropathy in order to evaluate whether abnormal transcapillary escape rate of albumin and procoagulant activity in these patients could be modified.
METHODS: A double-blind, randomized, controlled study was carried out at a tertiary referral centre. The subjects were 29 insulin-dependent diabetic patients with nephropathy. One year of fish oil supplementation (4.6 g n-3 fatty acids/day) was compared with placebo (olive oil). The main outcome measures were N-3 fatty acid proportions of platelet lipids, transcapillary escape rate of albumin, prothrombin fragment 1 + 2, thrombin-antithrombin complexes, markers of fibrinolysis, fibrinogen, factor VII antigen and activity, thrombomodulin, von Willebrand factor, platelet factor 4 and beta-thromboglobulin. These were measured every 6 months.
RESULTS: Neither transcapillary escape rate of albumin (7.4 (median) (5.0-9.8) (range) % vs. 7.0 (4.6-10.6) %) nor prothrombin fragment 1 + 2 (0.97 (0.72-2.40) nmol/L vs. 1.01 (0.59-3.11) nmol/L) changed after 12 months of fish oil supplementation.
CONCLUSION: Increased transcapillary escape rate of albumin and activity could not be modified during diet supplementation with fish oil in insulin-dependent diabetic patients with nephropathy.
