Objective: Circulating 8-iso-prostaglandin F 2α (8-iso-PGF 2α) has been proposed as new indicator of oxidative stress, which is involved in the pathophysiologic changes of atherosclerosis. We proposed to test the hypothesis that 8-iso-PGF 2α is an independent predictor of symptomatic peripheral arterial disease (PAD). Methods: A case-control study in 100 patients with symptomatic PAD and 100 control subjects matched for age, sex, and diabetes mellitus was conducted. Smokers and subjects using lipid-lowering drugs were excluded. Serum total 8-iso-PGF 2α was quantified with an enzyme immunoassay. Results: Median 8-iso-PGF 2α was higher in patients with PAD than in control subjects (63 vs 42 pg/mL; P =. 001). Logistic regression with hypertension, body mass index, and creatinine, low-density lipoprotein (LDL) cholesterol, triglyceride, high-sensitivity C-reactive protein (hs-CRP), 8-iso-PGF 2α, and total homocysteine concentrations as independent variables and case-control status as dependent variable revealed significant odds ratios (OR) for hypertension (OR, 3.74; 95% confidence interval [CI], 1.85-7.53), low-density lipoprotein cholesterol (OR, 1.16, for an increment of 10 mg/dL; 95% CI, 1.07-1.27), high-sensitivity C-reactive protein (OR, 1.02, for an increment of 1 mg/L; 95% CI, 1.00-1.03), and 8-iso-PGF 2α (OR, 1.11, for an increment of 10 pg/mL; 95% CI, 1.03-1.20). Conclusions: Serum total 8-iso-PGF 2α was an independent predictor of PAD in the population studied. This finding supports the hypothesis that 8-iso-PGF 2α is a risk marker for PAD. Our results indicate increased systemic oxidative stress in patients with PAD.
