Background: 8-iso-PGF2α is a family of PGF2α that could be offered as a non-invasive tool to represent in vivo oxidation status, as a link between oxidative milieus and vascular dysfunction.
Methods: A total of 45 patients with type 2 diabetes and 45 healthy adults were studied in this cross-sectional analysis. Blood samples were collected to measure the level of lipid profile, oxidative stress, and glycemic control indices. The sensitivity and specificity of 8-iso-PGF2α as a screening test were analyzed in the cut-off range 252 - 377.5 pg/mL and the corresponding receiver operating characteristics (ROC) were plotted to assess performance of the test.
Results: 8-iso-PGF2α level was significantly higher in the diabetic group (439.11 pg/mL ± 181.13 vs. 380.93 pg/mL ± 146.52). After adjustments for age, gender, and body mass index (BMI), linear regression analysis revealed that homeostasis model assessment of insulin resistance (HOMA-IR), blood pressure, fasting blood sugar (FBS), serum creatinine, insulin, oxLDL, and CRP levels are directly correlated with 8-iso-PGF2α in the 25% - 75% quartiles. Moreover, their mean levels were higher in quartiles with greater 8-iso-PGF2α levels. The cut-offs showing the best equilibrium between sensitivity and specificity approached 269.5 pg/mL with 83% and 62.5% sensitivity and specificity, respectively.
Conclusions: Our study provides evidence for the application of serum 8-isoPGF2α in the 25 - 75% quartile ranges to screen for the severity of oxidative reactions and glycemic control in vivo without need for any further in vitro enzymatic reactions, with higher levels, reflecting more severe oxidation and poor glycemic control.
