BACKGROUND AND OBJECTIVES Bacterial-derived DNA fragments (BDNAs) have been shown to be present in dialysis fluid, to pass through dialyzer membranes, and to induce IL-6 (IL-6) in mononuclear cells. The present study aimed at assessing the eventual presence of BDNAs in the blood of hemodialysis (HD) patients and if this is associated with markers of chronic(More)
Total quality in laboratory medicine should be defined as the guarantee that each activity throughout the total testing process is correctly performed, providing valuable medical decision-making and effective patient care. In the past decades, a 10-fold reduction in the analytical error rate has been achieved thanks to improvements in both reliability and(More)
BACKGROUND Saliva is an easily available biological material that is not commonly analysed in clinical chemistry, while it could give useful information especially in several oral diseases. METHODS In this work, the sulphur containing compounds cysteine, cysteinylglycine and glutathione were analysed in saliva of control subjects and periodontopathic(More)
The modifications of cell-mediated immunity in idiopathic thrombocytopenic purpura (ITP) were investigated using the technique of Moretta et al. [J. exp. Med. 151: 969-974, 1980] to study T lymphocyte subsets in 35 ITP subjects at various clinical stages. In all these patients, platelet-associated IgG (PAIgG) were measured by a complement lysis inhibition(More)
The aim of this study was to determine the most appropriate urine collection for detecting differences in the excretion rates of albumin, gamma glutamyl transpeptidase (GGT) and N-acetyl-beta-D-glucosaminidase (NAGA) between normotensive subjects and hypertensive patients on treatment. Twenty treated hypertensive patients, mean (SEM, standard error of mean)(More)
Mitogenic response of blood lymphocytes to phytohemagglutinin (PHA) and to OKT 3 monoclonal antibodies was investigated in 7 patients suffering from chronic idiopathic thrombocytopenic purpura (ITP) before, during and after high-dose intravenous (i. v.) immunogammaglobulin (IgG) infusion. The platelet count rose above the pre-treatment values during(More)
BACKGROUND AND OBJECTIVES The increased need in clinical chemistry laboratories for methods of homocysteine determination, in correlation with cardiovascular diseases and nutritional deficient status, has led to the development of different analytical methods; fluorescent immunoenzymatic assays and, recently, new fully automated spectrophotometric methods(More)
OBJECTIVES Recent studies describe the potential use of biochemical markers in the evaluation of the severity of periodontitis; moreover, patients suffering from periodontitis frequently complain of halitosis (breath malodour), mainly depending on volatile compounds (e.g. hydrogen sulphide, methyl mercaptan, etc.) produced by anaerobic metabolism of oral(More)
In the present work we investigated HDL-C and its subfractions HDL2 and HDL3 as well as total cholesterol (TC), triglycerides (TG), LDL-C, VLDL-C, apolipoproteins A1 (ApoA1) and B (ApoB) and lipoprotein (a) (Lp(a) in 25 patients with newly diagnosed acute lymphocytic leukemia (ALL) before and after induction treatment. The mean basal plasma levels of TC,(More)
