BACKGROUND Polycystic ovary syndrome (PCOS) causes an increased risk of metabolic cardiovascular syndrome. Also, cystatin C serum levels are associated with the risk of cardiovascular events in metabolic syndrome patients. OBJECTIVE To investigate the relationship between cystatin C in PCOS patients. MATERIALS AND METHODS 35 women with PCOS were compared to 35 women with healthy matched age...

BACKGROUND Cystatin C is a new interesting marker of glomerular filtration rate (GFR). However, data regarding its biological variance are scarce and conflicting. The ability of cystatin C to longitudinally follow renal function in patients therefore remains questionable. METHODS 12 healthy subjects (6 men and 6 women) were included in the final statistical analysis. Serum creatinine, plasma ...

Because all the patients had chronic kidney disease (CKD) (GFR <55 mL/min per 1.73 m 2 ), this study cannot be used to assert that cystatin C is definitively better than creatinine for detecting stage 3 kidney disease (GFR <60 mL/min per 1.73 m 2 ). Regarding the study methods, the authors do not mention when cystatin C was measured in the frozen samples. Were the samples measured retrospective...

It was first ...

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...

Cystatin A, a cysteine proteinase inhibitor, is a cornified cell envelope constituent expressed in the upper epidermis. We previously reported that a potent protein kinase C activator, 12-O-tetradecanoylphorbol-13-acetate, increases human cystatin A expression by the activation of AP-1 proteins. Here, we delineate the signaling cascade responsible for this regulation. Co-transfection of the cys...

BACKGROUND All of the components of metabolic syndrome (MetS) have been regarded as risk factors for coronary artery disease (CAD). Early detection of CAD in asymptomatic patients with MetS remains a challenge. Cystatin C,which has been proposed as a novel marker of renal dysfunction,is correlated with mortality in CAD, The purpose of the study was to evaluate whether cystatin C is a potential ...

BACKGROUND Cystatin C is a marker of acute kidney injury (AKI). However, systemic inflammation associated with sepsis, a common AKI-trigger, may affect cystatin C. We studied the impact of sepsis on cystatin C levels in plasma. Furthermore, we investigated whether the presence of sepsis affects the predictive properties of cystatin C. METHODS Three hundred and twenty-seven intensive care unit...

BACKGROUND Recent research has shown cystatin C to predict mortality and cardiovascular morbidity independent of renal function. The aim of this study was to evaluate the prognostic value of cystatin C on mortality in adult general ICU patients with acute kidney injury (AKI). We later expanded the study and included patients without signs of AKI. METHODS A total of 845 ICU patients were analy...

INTRODUCTION In critically ill patients sudden changes in glomerular filtration rate (GFR) are not instantly followed by parallel changes in serum creatinine. The aim of the present study was to analyze the utility of serum cystatin C as a marker of renal function in these patients. METHODS Serum creatinine, serum cystatin C and 24-hour creatinine clearance (CCr) were determined in 50 critica...
