BACKGROUND/AIMS Height-adjusted total kidney volume (htTKV) is the best marker of disease progression in early autosomal dominant polycystic kidney disease (ADPKD) when renal function still remains normal. The usefulness of cystatin-C as a biomarker to assess renal function according to renal volume has not been studied in ADPKD patients. METHODS Observational and cross-sectional study of 62 ...

Shrunken Pore Syndrome was recently suggested for the pathophysiologic state in patients characterized by an estimation of their glomerular filtration rate (GFR) based upon cystatin  C, which is lower or equal to 60% of their estimated GFR based upon creatinine, i.e. when eGFR cystatin  C ≤ 60% of eGFR creatinine. Not only the cystatin C level, but also the levels of other low molecular mass pr...

PURPOSE The purpose of this study was to evaluate the accuracy of plasma cystatin C in acute impairment in renal function; plasma cystatin C was compared to plasma creatinine in two hundred patients undergoing elective CABG surgery. METHODS We performed a prospective clinical study of two hundred patients undergoing coronary bypass surgery. Plasma creatinine and cystatin C were measured preop...

BACKGROUND We evaluated the predictive ability of cystatin C and creatinine-based estimations of glomerular filtration rate (eGFR), including the Chronic Kidney Disease-Epidemiology (CKD-EPI) equation, in acute coronary syndrome (ACS) patients with (STE-ACS) or without (NSTE-ACS) ST elevation in a large contemporary ACS population. METHODS Concentrations of cystatin C and creatinine, as well ...

Background. The aim of the present study was to examine sources of variation for serum cystatin C in a healthy Greek population. Methods. Cystatin C together with basic clinical chemistry tests was measured in a total of 490 adults (46 ± 16 yrs, 40% males) who underwent an annual health check. Demographic, anthropometric, and lifestyle characteristics were recorded. Results. Higher values of cy...

Cystatin C has been regarded as a novel sensitive marker for the assessment of renal function, and the role of cystatin C as a predictor of cardiovascular events in patients with impaired renal function has been confirmed in clinical studies. In this study we assessed the association between cystatin C and Coronary artery disease [CAD] in a consecutive series of patients with normal kidney func...

In clinical practice, the measurement of endogenous serum substances in order to estimate glomerular filtration rate (GFR) is commonly performed, and the serum creatinine level has become the most commonly used serum marker of renal function. However, the measurement of the serum creatinine concentration can sometimes lead to an overestimation of GFR, especially in the elderly. In recent years,...

BACKGROUND We recently reported a relationship between plasma levels of cystatin C and incidence of the metabolic syndrome (MetS) among the first 2,369 subjects who participated in the re-examination study of the population-based Malmö and Diet Cancer Cardiovascular cohort (MDC-CC-re-exam). In this study we aimed to replicate these results and also investigate if cystatin C was causally associa...

INTRODUCTION AND OBJECTIVES The protein cystatin C has a stable plasma concentration and is eliminated exclusively by the kidneys. The aim of this study was to determine the prognostic value of cystatin C in patients with acute coronary syndrome (ACS). METHODS The prospective study included 203 hospitalized ACS patients. Clinical evaluation during the first 24 hours of hospitalization include...
