Abstract |
Contrast-induced nephropathy (CIN) accounts for 10% of hospital-acquired renal failure, causes a prolonged in- hospital stay and represents a powerful predictor of poor clinical outcome. The underlying mechanism of the CIN development remains unclear and seems to be multifactorial. The potential link between platelet indices such as mean platelet volume (MPV) and platelet distribution width (PDW) with CIN is unknown. Herein, we aimed to investigate the correlation between MPV and PDW levels with the development of CIN. The incidence of CIN (20.5%) was prospectively evaluated in 430 patients with diagnosis of acute coronary syndrome. Initial creatinine (1.13 ± 0.25 vs. 1.05 ± 0.27 mg/dl, P = 0.01) and PDW (40.1 ± 20.2 vs. 34.5 ± 19.9%, P = 0.02) levels and the total volume of contrast media used (121 ± 61 vs. 94 ± 42 ml, P = 0.01) were higher in patients who developed CIN. MPV was similar between the two groups (P = 0.80). In a univariate regression analysis, age, increased creatinine, uric acid, phosphate, PDW levels and higher total volume of contrast media used were significantly correlated with CIN incidence. However, in a multivariate analysis, only total volume of CM used [odds ratio (OR) 1.011, 95% confidence interval (CI) 1.006-1.016; P = 0.01], increased age (OR 1.026, 95% CI 1.00-1.052; P = 0.05) and increased PDW levels (OR 1.009, 95% CI 1.00-1.022; P = 0.04) remained as the independent predictors of CIN. Among platelet indices, PDW, but not MPV, was associated with CIN development. The clinical significance of such link remains unclear, but may indicate involvement of platelet activation in CIN pathogenesis.
