Subjects suffering from lipoprotein lipase (LPL) deficiency show very severe hypertriglyceridemia, often accompanied by recurrent bouts of pancreatitis. Dietary intervention is currently considered first-line treatment of this condition in paediatric age. The aim of our study was to compare the effects of dietary treatment with a low-fat diet alone and a low-fat diet enriched with omega-3-fatty acids.


The data of 11 patients with LPL deficiency who were diagnosed in our lipid clinic between October 1997 and October 2007 were summarised. All patients had been treated with a low-fat diet, and in addition a group of five patients received supplements of omega-3-fatty acids over a period of at least 5 months.


After adjustment for pre-intervention TG concentration, there was a statistically significant difference in post-intervention TG concentrations between the interventions, F(1,8) = 13.529, P = 0.006, partial η2 = 0.628. Post-intervention-adjusted TG concentrations were statistically significantly greater in the low-fat diet group vs the w3 diet group (P <0.05).


We provide first evidence that a low-fat diet supplemented with omega-3-fatty acids results in a pronounced decrease in TG in paediatric patients affected with LPL deficiency. However, further studies are necessary to evaluate the long-term effects and safety of omega-3-fatty acids.
