Abstract
Introduction:
Peripheral artery disease (PAD) is mainly caused by atherosclerosis but also involves hyperglycemia and dyslipidemia, which trigger oxidative stress and lead to vascular damage.Objectives:
To determine the prevalence of PAD in patients with type 2 diabetes mellitus (DM2) and/or prediabetes and/or dyslipidemia, to identify some risk factors and to establish whether urinary levels of 8-isoprostane-f2α (an oxidative stress marker) are elevated in patients with PAD.Design:
A cross-sectional, nonprobabilistic, convenience sampling study Materials andmethods:
The sample included 146 patients with DM2 and/or prediabetes and/ or dyslipidemias from the Universidad Nacional de Colombia. Risk factors, symptoms related to PAD, ankle-brachial index measurement and biochemical variables (HbA1c%, fasting blood glucose, lipid profile, creatinine and albuminuria) were recorded. Urine levels of 8-isoprostane-f2α were determined by ELISA. The 8-iso-PGF2α/creatine concentration were analyzed using the statistical package R. Risk factors were compared using ANOVA/ Kruskal-Wallis. ROC curves were generated to analyze the discriminant power of the biomarkers. The joint analysis of laboratory results and risk factors was performed using multivariate logistic regressions.Results:
PAD was identified in 10 diabetic patients. Risk factors were smoking, dyslipidemia, poor metabolic control, overweight or obesity. There was no evidence of increased urinary 8-isoprostane-f2α in these subjects.Conclusions:
A low prevalence of PAD was found in subjects with DM2. There was no evidence of increased 8-isoprostane-f2α measured by ELISA in patients with PAD. The extension of the study with different markers of oxidative stress and the use of other techniques is recommended (Acta Med Colomb 2019; 44. DOI https//doi.org/10.36104/amc.2019.1257).
