No association between the cystatin C gene polymorphism and Alzheimer's disease: a case-control study in an Italian population.

2005

Cystatin C is an amyloidogenic protein found together with beta-amyloid in cerebral arteriolar walls of both patients with Alzheimer's Disease (AD) and conghopilic amyloid angiopathy. Several findings implicate cystatin C in the pathogenesis of vascular diseases. Recent genetic association studies proposed cystatin C gene (CST3) as a susceptibility factor for AD, although other reports did not replicate this finding. We conducted a case-control study including 192 probable AD cases and 192 age- and sex-matched controls to test the association between CST3 and AD. Possible interaction between CST3 and age at onset of AD or apolipoprotein E (APOE) was also examined. No significant differences…

Comparison of cystatin C and creatinine-based glomerular filtration rate formulas with 51Cr-EDTA clearance in patients with cirrhosis

2011

Renal function is an important predictor of survival in cirrhosis and liver transplantation. GFR estimates using serum cystatin C (CysC) are proposed as better predictors of renal function than ones on the basis of serum creatinine (Cr). Our aims were: (1) evaluate correlations between serum CysC and different methods of creatinine measurements; (2) compare CysC and Cr GFR formulas with (51)Cr-EDTA; and (3) evaluate liver-related parameters potentially influencing GFR.254 blood samples in 65 patients with cirrhosis correlating CysC with four Cr methods were used; another 74 patients comparing (51)Cr-EDTA GFR to Modification of Diet in Renal Disease and Larsson and Hoek formulas for CysC wer…

Fetuin-A serum levels are not correlated to kidney function in long-lived subjects

2012

Objectives: Serum Fetuin A has been identified as an inhibitor of ectopic calcification. It is reduced in subjects with chronic kidney disease (CKD) and it has been proposed as a potential link between CKD and the higher prevalence of arterial calcification observed in these patients. During ageing both the stiffening of arterial wall due to calcification and a decline in kidney function are frequent. The aim of the study is to investigate if Fetuin A serum levels are associated with ageing and with AHSG T256S polymorphism. Moreover, we aim at investigate whether serum Fetuin A is correlated to kidney function in this setting of senescence. Design and Methods: 256 health long-lived subjects…

Serum interleukin-6 in patients with metastatic bone disease: correlation with cystatin C.

2008

The clinical significance of serum interleukin-6 (IL-6) and its correlation with cystatin C (Cyst C), an endogenous inhibitor of cysteine proteinase cathepsin K, was investigated by immunoassays in patients with bone metastasis from breast cancer (BCa) or prostate cancer (PCa). Additional studies were also performed in these patients to assess the effects of zoledronic acid (ZA) administration on the circulating levels of these molecules. Mean IL-6 and Cyst C serum concentrations were signifi- cantly increased in BCa patients and in patients with primary osteoporosis (PU) compared to healthy subjects (HS). However, Cyst C, but not IL-6, resulted significantly more elevated in BCa patients t…

Circulating cathepsin K and cystatin C in patients with cancer related bone disease: clinical and therapeutic implications.

2007

Abstract The clinical significance of serum cathepsin K and cystatin C was assessed in patients with breast cancer (BCa) or prostate cancer (PCa) with confined disease (M0) or bone metastasis (BM). Cathepsin K and cystatin C circulating levels were determined by ELISAs in 63 cancer patients, in 35 patients with nonmalignant diseases and in 42 healthy blood donors (control group). In BCa patients, cathepsin K serum levels were significantly lower than in sex matched control group (HS; p  = 0.0008) or in patients with primary osteoporosis (OP; p  = 0.0009). On the contrary, cystatin C levels were significantly higher in BCa patients than in HS ( p  = 0.0001) or OP ( p  = 0.017). In PCa patien…
