Urine Cofilin-1 Detection for Predicting Type 1 Cardiorenal Syndrome in the Coronary Care Unit: A Gold Nanoparticle- and Laser-Based Approach

Abstract

Background: Type 1 cardiorenal syndrome (CRS) is a severe complication for acute decompensated heart failure patients. This study aimed at evaluating the feasibility of using the gold nanoparticle-based localized surface plasmon-coupled fluorescence biosensor (LSPCFB) to detect urine cofilin-1 as a biomarker for predicting CRS among patients in the coronary care unit (CCU). Methods: A total of 44 patients were included with prospectively collected urine and blood samples. Both LSPCFB and conventional enzyme-linked immunosorbent assays (ELISAs) were used to measure urine cofilin-1 at admission to the CCU. The occurrence of CRS was judged within 7 days after admission. The discrimination presented as the area under the receiver operating characteristic curve (AUROC) and calibration of both detection methods were used to assess the predictive ability of urine cofilin-1 measured by the LSPCFB and ELISA. Results: Thirteen patients were diagnosed with CRS, while the other 31 patients were classified into a non-CRS group. For predicting CRS by measuring urine cofilin-1, the LSPCFB had higher accuracy (AUROC: 0.707, p = 0.031; overall accuracy: 79.55%) than the ELISA (AUROC: 0.479, p = 0.827; overall accuracy: 53.27%). The positive and negative predictive values of the LSPCFB were also higher than those of the ELISA (positive predictive value: 70.0 vs. 34.8%; negative predictive value: 82.4 vs. 76.2%). Conclusions: The gold nanoparticle-based immunoassay LSPCFB could exploit the potential of urine cofilin-1 as a single biomarker to predict CRS among CCU patients.

Discovery of potential plasma protein biomarkers for acute myocardial infarction via proteomics

“…Cofilin-1 (CFL1), as actindepolymerizing factors, play an essential role in the dynamics of filaments (34). Other research reported that the gold nanoparticle-based immunoassay localized surface Plasmon-coupled fluorescence biosensor could exploit the potential of urine cofilin-1 as a single biomarker to predict cardiorenal syndrome among coronary care unit patients (35). Dickkopf-related protein 3 (DKK) is a secretory protein involved in vascular smooth muscle cell differentiation and the regulation of myocardial remodeling; however, little is known regarding its role in atherosclerosis.…”

Cardiorenal Syndrome: New Pathways and Novel Biomarkers

“…Urinary cofilin-1 is another intriguing biomarker that acts as a modulator of epithelial-mesenchymal transition or de-differentiated renal tubular cells, which are essential for AKI and renal function recovery [ 71 ], and is related to severity of HF [ 72 ]. The group of Hsing-Yu Chen et al [ 73 ] measured cofilin-1 in 44 patients: 13 patients were diagnosed with CRS, while the other 31 patients were classified into a non-CRS group; they predicted the occurrence of CRS and differentiated CRS patients from non-CRS patients, using the gold nanoparticle-based localized surface plasmon-coupled fluorescence biosensor with a significant accuracy ( p = 0.031; overall accuracy 79.55%).…”
