AIMS To evaluate the effect of weight loss after bariatric surgery (BS) on peripheral adipocytokines, renal parameters and other cardiovascular risk factors (CVRFs). METHODS A total of 70 (41 women) extremely obese adults were prospectively studied before and 12 months after surgery. CONTROLS 24 (15 women) normal-weight adults. Anthropometric,(More)
Criteria for renal biopsy in proteinuric type 2 diabetes mellitus (T2DM) patients have been not defined. Usually criteria for renal biopsy in type 1 diabetes mellitus (T1DM) are used (microhaematuria, absence of diabetic retinopathy (DR), uncharacteristic change in renal function or immunological abnormalities). The aim of this study was to reconsider the(More)
BACKGROUND The aim of this study was to compare the accuracy of prediction equations [modification of diet in renal disease (MDRD), simplified MDRD, Cockcroft-Gault (CG), reciprocal of creatinine and creatinine clearance] in a cohort of patients with type 2 diabetes. METHODS A total of 525 glomerular filtration rates (GFRs) using (125)I-iothalamate were(More)
BACKGROUND Cardiovascular diseases are the leading cause of death in haemodialysis patients. Hyperhomocysteinaemia is an independent risk factor. Basic research has provided strong evidence that oxidation of low-density lipoprotein (LDL) plays an important role in the pathogenesis of atherosclerosis. Oxidative stress, lipid metabolism alterations, and(More)
BACKGROUND Cardiovascular disease is the principal cause of morbidity and mortality in haemodialysis patients. The classic risk factors do not account for all cases of elevated cardiovascular disease in this patient population and it is becoming increasingly clear that other cardiovascular risk factors are implicated. The objective of this study was to(More)
INTRODUCTION Various studies describe the pleiotropic antiinflammatory and antioxidant effects of atorvastatin, in addition to its hypolipemic effects. It has been suggested that statins modify glucose homeostasis via their antiinflammatory effects. A further hypothesis suggests that the incidence of posttransplantation diabetes is lower in statin-treated(More)
The high incidence of new-onset diabetes mellitus after transplantation (NODAT) suggests the need to find new factors to explain the pathogenesis. Our objectives were (1) to confirm that low levels of pre-transplant adiponectin are an independent risk factor for the development of NODAT in a larger transplanted population; (2) to analyze whether adiponectin(More)
We performed a cross-sectional study to determine the best method for estimating the glomerular filtration rate (GFR) in HIV-infected subjects. Isotopic GFR was correlated with 24-h urine creatinine clearance, cystatin C levels, and 3 creatinine-based equations-the Modification of Diet in Renal Disease (MDRD), Cockcroft-Gault (CG), and Chronic Kidney(More)
BACKGROUND/AIMS Glomerular kidney disease (GKD) is suspected in patients based on proteinuria, but its diagnosis relies primarily on renal biopsy. We used urine peptide profiling as a noninvasive means to link GKD-associated changes to each glomerular entity. METHODS Urinary peptide profiles of 60 biopsy-proven glomerular patients and 14 controls were(More)
BACKGROUND/AIMS Statins are prescribed in kidney transplant recipients in order to manage dyslipidemia, a common complication in these patients. The efficacy of statins in reducing cholesterol levels has been accompanied by pleiotropic effects. Fifty-four kidney transplant patients were included in the present study, the objective of which was to ascertain(More)
