Urinary clusterin concentrations--a possible marker of nephropathy? Pilot study.

Background: Clusterin is a glycoprotein which participates in a number of pathophysiological processes in the organism. Information about clusterin use in the diagnosis of nephropathy and the differential diagnosis of proteinuria has been published recently.

Aim: Search for correlations between urinary clusterin concentration and other renal function markers.

Treatment with atorvastatin reduces serum adipocyte-fatty acid binding protein value in patients with hyperlipidaemia.

Background: Adipocyte-fatty acid binding protein (A-FABP) is a circulating protein expressed in adipocytes and macrophages. Several recent studies demonstrated that A-FABP might be involved in the pathogenesis of metabolic syndrome, particularly in dyslipidaemia, insulin resistance and atherosclerosis. The aim of this study was to investigate the influence of atorvastatin treatment (20 mg day(-1) for 3 months) on serum A-FABP value in subjects with hyperlipidaemia.

[Adiponectin and insulin sensitivity].

Background: Adiponectin is a fat tissue protein that plays a role in maintaining the homeostasis of glucose and lipids, along with counteracting a number of risk factors associated with atherosclerosis and obesity. In addition, adiponectin has an effect on insulin sensitivity. The aim of this work was to assess concentrations of adiponectin in predefined groups of individuals and to analyse the associations between adiponectin and other metabolic parameters.

Assessment of serum beta-trace protein (BTP) measurement in the prediction of glomerular filtration rate. Comparison with serum cystatin C.

Serum BTP measurement is sometimes believed to be an alternative marker of glomerular filtration rate (GFR) assessment. The aim of the present work was to investigate the correlation between creatinine, cystatin C, and BTP values in sera and to compare the diagnostic efficacy for serum BTP and cystatin C with the glomerular filtration rate estimate. 25 individuals were tested.

The antioxidant acetylcysteine reduces oxidative stress by decreasing level of AOPPs.

Oxidative stress and especially its connection with many diseases has been discussed much recently. Among markers of oxidative stress there appear new and quite specific ones called advanced oxidation protein products (AOPPs). We tried to influence the level of AOPPs by an antioxidant therapy with N-acetylcysteine.
