Association between plasma levels of pigment epithelium-derived factor and renal dysfunction in patients with coronary artery disease
Cardiol J 2011;18(5):515-520.
Abstract
Background: Although plasma pigment epithelium-derived factor (PEDF) levels have been
shown to be significantly correlated with the levels of creatinine (Cr) in type 2 diabetes, little is
known about the association between PEDF levels and renal dysfunction in patients with
coronary artery disease (CAD).
Methods: We enrolled 134 consecutive patients with diagnosed CAD and measured plasma levels of PEDF, serum Cr, uric acid (UA) and high-sensitive C-reactive protein (hsCRP).
Results: Plasma PEDF levels were positively correlated with serum Cr (p < 0.0001) and UA (p < 0.0001) and negatively correlated with the estimated glomerular filtration rate (eGFR) (p < 0.0001), whereas there was no association between plasma PEDF and age or hsCRP. When the subjects were divided into five groups (0–4) according to the number of metabolic factors (obesity, diabetes, hypertension and dyslipidemia), PEDF levels in patients with four factors were significantly higher than those in patients without factors. Next, we divided the patients into quartiles according to their plasma PEDF levels (< 9.9 μg/mL, 9.9–12.8, 12.9– –15.7, > 15.7). The eGFR in the first group was significantly higher than those in the third and fourth groups. Multivariate logistic analysis indicated that eGFR (p < 0.0001) and age (p = 0.030) were significant independent variables that correlated with the quartile classification according to PEDF levels.
Conclusions: This study revealed that PEDF may play a role in renal dysfunction in CAD patients.
