BACKGROUND Epidemiological studies show that high circulating cystatin C is associated with risk of cardiovascular disease (CVD), independent of creatinine-based renal function measurements. It is unclear whether this relationship is causal, arises from residual confounding, and/or is a consequence of reverse causation. OBJECTIVES The aim of this study was to use Mendelian randomization to inve...
OBJECTIVE Patients with nasopharyngeal carcinoma experience highly variable outcomes despite receiving similar therapeutic regimens. Identifying biomarkers that predict survival and guide individualized therapy is urgently needed. Cystatin C has been explored as a valuable prognostic marker in several malignancies. We retrospectively assessed the relationship between serum cystatin C levels and...
Sir, The paper by Kimmel et al. [1] concludes that cystatin C blood level variations are a more reliable parameter than serum creatinine increments for the diagnosis of contrastinduced nephropathy (CIN). However, this conclusion does not seem sufficiently supported by the data to us. Since the definition of CIN is based on serum creatinine variations, it is not clear what the meaning is of the ...
Background: There is limited data regarding the clinical utility of cystatin C in patients with stable coronary artery disease (CAD). The aim of this study was to determine the predictive value of cystatin C for the presence and severity of CAD and the association between this protein and other biochemical risk factors for atherosclerosis in patients with suspected CAD. Methods: Ninety-four pat...
AIMS Serum cystatin C, a novel marker of kidney function, is reported to be superior to serum creatinine as a risk factor for atherosclerotic disease, but associations may vary across vascular beds. METHODS AND RESULTS A cross-sectional study of chronic kidney disease (CKD) and peripheral arterial disease (PAD) in 3089 adult participants aged 40+ from the 1999-2002 National Health and Nutriti...
BACKGROUND Adding the measurement of cystatin C to that of serum creatinine to determine the estimated glomerular filtration rate (eGFR) improves accuracy, but the effect on detection, staging, and risk classification of chronic kidney disease across diverse populations has not been determined. METHODS We performed a meta-analysis of 11 general-population studies (with 90,750 participants) an...
OBJECTIVE To compare serum cystatin C levels, a novel biomarker of renal function, in adolescents with and without type 1 diabetes and to determine what factors affect cystatin C levels. RESEARCH DESIGN AND METHODS Cystatin C was measured in youth 12-19 years of age with (n = 259, diabetes duration 9 ± 3 years, HbA(1c) 8.9 ± 1.6%) and without diabetes (n = 78). Data were compared by diabetes ...
BACKGROUND Cystatin C has been proposed as a novel marker of renal function and predictor of cardiovascular risk. The aim of this study was to investigate the role of cystatin C level as a predictor of cardiovascular events in patients with coronary artery disease (CAD). METHODS Three hundred and five coronary artery patients were included in this study. Serum cystatin C levels, high-sensitiv...
BACKGROUND Serum levels of cystatin C, an endogenous inhibitor of cysteine proteases, provide an alternative method to creatinine-based criteria for measuring glomerular filtration rate. Preliminary data suggested that serum cystatin C levels parallel with the stage of liver fibrosis in chronic liver disorders. Our aim has been to evaluate the possible role of serum cystatin C as a marker of li...
Background: Accurate and rapid assessment of allograft function is essential in renal transplant recipients in order to detect allograft rejection and to monitor drug nephrotoxicity. We aimed to evaluate the usefulness of cystatin C as a marker of kidney allograft function in the early post-transplant period and to compare this value with that of conventional serum creatinine concentration. Met...
