BACKGROUND The first step in the diagnosis of diabetic nephropathy is to measure albumin in a spot urine sample. The aim of this study was to assess the accuracy of urinary albumin concentration (UAC), urinary albumin-to-creatinine ratio (UACR), and the Micral-Test II in a random urine specimen (RUS) for microalbuminuria screening in diabetes mellitus.

AIM To analyse the performance of HbA(1c) in diagnosing Type 2 diabetes based on fasting plasma glucose and/or 2-h plasma glucose measurements after a 75-g oral glucose tolerance test. METHODS This is a study of diagnostic test accuracy in individuals referred to the Clinical Pathology Department for oral glucose tolerance testing. After fasting(More)
To analyse the accuracy of the conversion formulae for estimation of glycohaemoglobin (GHb) measured by different methods, we analysed 210 samples for HbA1c using HPLC. Fifty of these specimens were analysed by micro-column chromatography (MC), 43 by electrophoresis (EP), 50 by IMX system (Abbott Laboratories), 38 by Primus HPLC and 29 by Diamat HPLC.(More)
Glycohemoglobin (GHb) has a key role in the assessment of glycemic control in diabetic patients. Several studies have clearly shown that improved glycemic control is strongly associated with decreased development and/or progression of diabetic complications in both type 1 and 2 diabetes mellitus. Therefore, accurate determination of GHb concentration is an(More)
Metabolic syndrome (MS) identifies cardiovascular risk; however, there is little information regarding the evolution of patients with MS after stent implantation. The aim of this single-center study is to evaluate the possible association between MS and clinical restenosis, after adjustment for highsensitivity C-reactive protein (hs-CRP) and angiographic(More)
AIMS To identify the causes of very low glycohaemoglobin (GHb) values in a sample of patients with diabetes in southern Brazil using high performance liquid chromatography. METHODS Between August 1996 and December 2001 all samples from patients with diabetes at a university hospital with GHb values below the reference range (4.7-6.0% HbA(1c)) were(More)
AIMS To analyze in a random urine spot the predictive value of urinary albumin concentration (UAC) for cardiovascular events, diabetic nephropathy (DN), and death in patients with type 2 diabetes. METHODS In this cohort, urinary albumin (immunoturbidimetry) was measured as 24-h urinary albumin excretion (UAE) and, in a random spot urine, as UAC and(More)
BACKGROUND Current data are conflicting about the influence of gender on cystatin C concentrations. The goal of this study was to determine the reference interval for serum cystatin C in normal Brazilian subjects, taking into account the influence of gender. METHODS Ninety-seven healthy volunteers, aged 18-70 years, 44% male, had glomerular filtration(More)
The aim of the present study was to analyze the fatty acid composition and cholesterol content of the beef and chicken meat most often consumed by a population of type 2 diabetic patients in Southern Brazil: for beef, semimembranosus and biceps femoris; and for chicken, drumstick and thigh. The moisture content (gravimetrically), protein content (Kjeldahl(More)
-Four groups of 10 young adult Wistar male rats were fed ad libitum on a protein-free diet for periods of 7, 28, 56 and 84 days. Control groups were fed on a 20o% casein diet. Food intake and body weights of rats were registered. Plasma protein levels and liver weight and fat content were determined. Sections of the caudate lobe were studied histologically.(More)
