Aim.
An exploration of ethnic differences in measures of oxidative stress and endothelial activation in relation to known cardiovascular risk factors within South Asians (SA) and White Europeans (WE) residing in the UK.
Methods.
202 participants within a UK multiethnic population provided biomedical and anthropometric data.
Human urinary 2,3-dinor-8-iso-prostaglandin-F1α and plasma ICAM-1 were quantified as measures of oxidative stress and endothelial activation, respectively.
Results.
2,3-Dinor-8-iso-prostaglandin-F1α levels were significantly higher in the SA group compared to WE group (10.36 (95% CI: 9.09, 11.79) versus 8.46 (7.71, 9.29), P=0.021) after adjustment for age, gender, smoking status, body weight, HbA1c, and medication.
Oxidative stress was positively associated with HbA1c (β=1.08, 95% CI:1.02, 1.14, P=0.009), fasting (β=1.06, 95% CI: 1.02, 1.10, P=0.002), and 2 hr glucose (β=1.02, 95% CI: 1.00, 1.04, P=0.052).
In each adjusted model, SA continued to have elevated levels of oxidative stress compared to WE.
ICAM-1 levels were significantly higher in the composite IGR group compared to the normoglycaemic group (P<0.001).
No ethnic differences in ICAM-1 were observed.
Conclusion.
These results suggest that SA are more susceptible to the detrimental effects of hyperglycaemia-induced oxidative stress at lower blood glucose thresholds than WE.
Further research into the potential mechanisms involved is warranted.
