Dyslipoproteinemia, a feature of systemic lupus erythematosus may contribute to premature atherosclerosis. In order to develop an experimental model for this dyslipoproteinemia we measured plasma concentrations of lipoproteins in juvenile NZB/W (lupus) and NZB/B (control) mice. Additionally to evaluate the effects of a diet rich in n - 3 fatty acids we measured lipoprotein concentrations in mice on normal or menhaden oil-enriched diets. The lupus mice had elevated triglycerides compared to the controls, similar to that seen in human SLE patients (161 ± 31 vs. 113 ± 13 mg/dl, P < 0.003). In contrast, the menhaden oil diet fed NZB/W mice had triglycerides similar to the NZB/B control fed group. In the NZB/W murine SLE model, dyslipoproteinemia is an early sign of disease as has been shown in man, therefore this model will be useful in elucidating the mechanism of dyslipoproteinemia in SLE.
