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. MATERIALS AND METHODS: Anthropometric and serum analyses were performed for body mass index, A-FABP, triglycerides, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, uric acid, alanine aminotransferase (ALT), aspartate aminotransferase (AST), high sensitive C-reactive protein (hs-CRP), creatine kinase (CK) and glucose on 26 subjects (BMI 30.3 +/- 6.0, mean age 62 +/- 10 years) with hyperlipidaemia who met the criteria: total cholesterol > 5.2 mmol L(-1), LDL cholesterol > 3.3 mmol L(-1) and triglycerides < 3 mmol L(-1). RESULTS: After the 3-month therapy, a significant reduction in total cholesterol (P < 0.001), LDL cholesterol (P < 0.001), glucose (P < 0.001), A-FABP (from 44.6 +/- 26.2 to 38.6 +/- 19.3 g L(-1), P < 0.01), uric acid (P < 0.05), AST (P < 0.05) and triglycerides (P < 0.05) values was observed. No difference was found in BMI, CK, ALT, hs-CRP, or HDL cholesterol values. A significant difference in the serum A-FABP value before and after the therapy remains after the correction for total cholesterol value (P < 0.001). A positive correlation between serum A-FABP and glucose was found (P < 0.05). CONCLUSIONS: In conclusion, our study confirmed in vivo that atorvastatin reduces serum A-FABP by a pleiotropic mechanism and supports the hypothesis that A-FABP is involved in atherosclerotic actions.

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. Evaluation of urinary clusterin measurement use in the differential diagnosis of nephropathy. METHODS: Urea, creatinine, IgG, transferin, Na, K in serum and 24-hour collected urine were measured in a sample of 82 individuals. Cystatin C in sera was also measured as were GMT, alpha-1 microglobulin, albumin, total protein in urine. In all probands urinary clusterin was assayed (ELISA). RESULTS: Urinary clusterin values correlated with urinary total protein concentrations (r = 0.28; p = 0.018), total protein/creatinine index (r = 0.26; p = 0.02). No correlation was found between urine clusterin concentration and glomerular filtration rate, age, urine GMT/creatinine, alpha-1-microglobulin, urine albumin and albumin/creatinine ratio or Na, K fractional excretions. We found no urinary clusterin differences by sex of probands. No evidence of any relationship between urine clusterin and presence of defect of renal function, number of risk factors (chi(2) = 16.0; DF = 15; p = 0.38), albumin/creatinine index (chi(2) = 0.76; DF = 3; p = 0,86), total protein/creatinine (chi(2) = 6.5; DF = 3; p = 0.09), GMT/creatinine (chi(2) = 2.3; DF = 3; p = 0.51), high urinary alpha-1-microglobulin (chi(2) = 4.1; DF = 3; p = 0.25) or decreased of GFR (chi(2) = 1.3; DF = 3; p = 0.74). CONCLUSIONS: A positive correlation exists between urinary clusterin and urinary total protein and total protein/ creatinine index. Urinary clusterin measurement with ELISA test does not offer any advantage over routinely used parameters for nephropathy diagnosis and the differential diagnosis of proteinuria type.

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. GFR was estimated from creatinine clearance, serum cystatin C and BTP and urine alpha-1 microglobulin, albumin, GMT and creatinine were measured. BTP values correlated with cystatin C (r = 0.75; p < 0.01), creatinine (r = 0.73, p < 0.01), GFR (r = -0.46; p = 0.02), urine alpha-1-microglobulin (r = 0.66; p < 0.01). The diagnostic efficacy of BTP for reduced GFR was insufficient and the calculation of GFR with BTP was not included in the regression model.
