Abstract
Oxidative mechanisms involving lipid peroxidation in the subendothelium of the arterial vessel wall play a key role in atherogenesis Despite severe hyperlipidaemia patients with glycogen storage disease type la GSD1a do not develop premature atherosclerosis Therefore we analysed parameters of antioxidative defence and oxidative stress in plasma and serum of patients with GSD1a n=17 and compared them with those of patients with type 1 diabetes mellitus n=17 familial hypercholesterolaemia n=18 and healthy controls n=20 We measured the total radical trapping ability parameter TRAP single plasma antioxidants sulfhydrylgroups uric acid vitamin C alphatocopherol coenzymeQ10 markers of lipid peroxidation lipoprotein a and homocysteine Patients with GSD1a showed an elevated TRAP P001 compared to the three other groups This can mainly be attributed to elevated uric acid levels P005 versus control Lipoprotein a was significantly lower in the GSD1a group compared to the three other groups P005Conclusion Patients with glycogen storage disease type 1a show an increased antioxidative defence in plasma which may protect them against lipid peroxidation and thus against premature atherosclerosis Our finding of low lipoprotein a levels in this small group of patients warrants further investigation in a greater number of patients before assessing its role in atherogenesis in glycogen storage disease type 1a
