dc.description.abstractObjective: Acute renal failure (ARF) prevalence is high among patients who undergo cardiopulmonary bypass (CPB), and this condition can only be diagnosed via serum creatinine level (sCr) conventionally within 48 hours. Therefore, we need early novel diagnosis biomarkers to start preventive treatment of ARF. For that reason, we aimed to analyze if plasma miR-21 derived from heart, correlates with kidney- enriched miR-10a during inflammatory IL-6, IL-1 beta, and TNF-alpha response in terms of acute renal failure 30 minutes after CPB. Methods: Patients (n=46, Female:8 and Male:38), aged 61.08 +/- 9.41, who underwent CPB surgery were included. Blood samples were collected during the pre - and post-CPB (30 minutes after CPB). Demographic data of all cases were collected. Quantification of expression levels of miR-21 and miR-10a was done via quantitative PCR (qPCR). Determination of plasma concentration of relevant cytokines, IL-6, IL-1 beta, and TNF-alpha was done via ELISA. Results: The circulating level of miR-21 during post-CPB period (-11.78 +/- 6.98) was significantly higher (p <= 0.05) than pre-CPB period (-6.55 +/- 7.11), but there was no significant change (p>0.05) in the circulating level of miR-10a between pre - (-12.22 +/- 3.55) and post-CPB (-11.60 +/- 3.36) periods. When we compared the mean Delta Delta Ct values of miR-21 and miR-10a, downregulation was observed in the expression level of miR-10a (0.62 +/- 3.77) whilst the expression level of miR-21 (-5.22 +/- 7.25) was upregulated (p <= 0.05). The levels of plasma concentration of IL-6 (2.74 +/- 2.50 ng/l) and TNF-alpha (83.63 +/- 9.33 ng/l) were increased during post-CPB period (both were ***p<0.0001). Whilst, IL-1 beta concentration level during pre-CPB period (3.95 +/- 0.47 ng/l) was found to be decreased (0.38 +/- 2.04 ng/l and *p<0.05) according to post-CPB. Conclusion: Prospectively, these data suggests that high miR-21 levels is a promising indicator and can be a candidate as an early novel biomarker for diagnosis of acute renal failure 30 minutes after CPB.en_US
