Non-insulin-dependent (type II) diabetes mellitus is associated with significant abnormalities of lipoprotein metabolism. Control of glycemia rarely completely corrects the alterations in lipid metabolism, suggesting a participation of environmental and genetic factors. The observation that tumor necrosis factor (TNF) can modulate triglyceride metabolism(More)
OBJECTIVE Our goal was to test any association between human plasma circulating levels of monocyte chemoattractant protein-1 (cMCP-1) and insulin resistance and to compare monocyte chemoattractant protein-1 (MCP-1) adipose tissue gene expression and cMCP-1 in relation with inflammatory markers. RESEARCH METHODS AND PROCEDURES cMCP-1 was measured in n =(More)
BACKGROUND The occurrence of antineutrophil cytoplasmic antibodies (ANCA) has been reported more frequently than expected in healthy first-degree relatives of patients with ulcerative colitis, suggesting that these antibodies may represent a subclinical marker of genetic disease susceptibility. AIM To determine the prevalence of ANCA in unaffected(More)
BACKGROUND Silent cerebral white matter lesions are observed on magnetic resonance imaging (MRI) scans in elderly people, and they are related to vascular risk factors, particularly hypertension. No data on the prevalence and risk factors of white matter lesions in patients with chronic kidney disease (CKD) are available. The aim is to analyze the(More)
OBJECTIVE It has been suggested that the polymorphic variation of GLUT1 glucose transporter may contribute to genetic susceptibility to type 2 diabetes in some populations. We have evaluated the GLUT1-XbaI polymorphism in an association study of a Caucasian Mediterranean population and its role in the susceptibility to displaying either microangiopathic(More)
Genotypic abnormalities of the renin-angiotensin system have been suggested as a risk factor for the development of microangiopathic complications in diabetic patients. We studied the relationship of either an insertion-deletion polymorphism in the angiotensin-converting enzyme (ACE) gene and the M235T and T174M variant polymorphisms of the angiotensinogen(More)
BACKGROUND Although there is strong evidence implicating genetic predisposition in the pathogenesis of the chronic inflammatory bowel diseases, the number and identity of susceptibility genes remain uncertain. Cytokine genes are tentative candidate loci, but data regarding association studies in different populations are conflicting. AIMS To determine(More)
BACKGROUND The results of 5 years of experience (2004-2008) with process-based quality management using quality indicators for key laboratory processes (analytic and extra-analytic) in a group of clinical laboratories affiliated with the Catalan Health Institute are presented. Our purpose was to analyze the evolution of the indicators, identify processes(More)
BACKGROUND The aim of the present study was to determine the prevalence and diagnostic usefulness of antineutrophil cytoplasmic antibodies (ANCA) in a Spanish population of patients with inflammatory bowel disease from the province of Tarragona. PATIENTS AND METHODS One hundred and fifty-six sera obtained from 116 patients with inflammatory bowel disease(More)
OBJECTIVES Treated HIV-1-infected patients with lipodystrophy often develop insulin resistance and proatherogenic dyslipidaemia. Zinc alpha-2 glycoprotein (ZAG) is a recently characterized adipokine which has been shown to be involved in the development of obesity and metabolic syndrome in uninfected subjects. We assessed the relationship between(More)
