ABSTRACT
Introduction:
Down Syndrome (trisomy 21) provides an interesting natural model to study atherosclerosis, since these individuals appear to be protected from plaque formation.Methodology:
We assessed the lipid levels, and superoxide dismutase (SOD) activity in 32 clinically diagnosed children of Down syndrome and 34 children matched for age and sex as controls.Results:
SOD activity was found to be significantly higher (p=0.004) in children with Down Syndrome (mean=313.7 IU/ml) than in controls (mean140.2 IU/ ml). Significantly higher levels of serum triglyceride (154.7 mg/dl) and VLDL (33.9 mg/dl) were observed in Down Syndrome as compared to healthy controls (119.6 mg/dl and 23.9 mg/dl respectively; p<0.05 for each). However, the two groups did not show any significant difference in levels of serum HDL-C, LDL-C.Conclusion:
The raised antioxidant activity of SOD, because of over expression of genes situated non chromosome 21, probably offers some protection against the development of atherosclerosis despite the occurrence of dyslipidemia.
