Obesity is a health problem that is reaching epidemic proportions. Extreme obesity (body mass index [BMI] > or =40 kg/m2) is a type of obesity that usually does not respond to medical treatment, with surgery being the current treatment of choice. Extreme obesity is associated with cardiovascular disease, type 2 diabetes, dyslipidemia, and hypertension.(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)
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)
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)
Disseminated varicella zoster virus (VZV) infection is a rare complication after renal transplantation in adults. We report 4 cases diagnosed in our transplant patients. One of which was a primary infection (chicken pox) with multivisceral involvement (hepatitis, pneumonitis, myocarditis, and disseminated intravascular coagulation). The other 3 patients(More)
BACKGROUND Podocyte proteins are involved in the pathogenesis of glomerular kidney disease (GKD). However, there is little information on messenger RNA (mRNA) expression patterns of B7-1 and NPHS1 in urinary sediment of patients with GKD. The objective of this study was to analyse the gene expression of B7-1 in urinary sediment and correlate it with the(More)
BACKGROUND Inflammation plays an important role in the pathogenesis of ischemic acute kidney injury (IAKI). In this study, we hypothesize that transplant recipients with pretransplant inflammation may have a greater chance of developing delayed graft function (DGF), an example of IAKI. PATIENTS AND METHODS We analyzed 178 patients who had undergone their(More)
We present a case of IgA nephropathy diagnosed by renal biopsy that presents after 2 years of folow-up an impairment of the renal function associate histoligically to a crescentic glomerulonephritis. The immunologic determinations showed of high titers of antineutrophil cytoplamic antibodies (ANCA) (P-ANCA IgG antiMPO and P-ANCA IgA anti-MPO). The patient(More)
This prospective study evaluated the relationship between inflammation and oxidative stress in a group of dialysis patients just before and 3 months after kidney transplantation and compared the results with a control group of healthy subjects. The oxidative stress markers determined were different F2-isoprostane isomers. The inflammatory markers included(More)
BACKGROUND There are few reports about the clinical course and prognosis of monoclonal gammopathy of undetermined significance (MGUS) in long-term immunosuppressed patients. Our aim was to study the association and evolution of MGUS and renal transplantation. METHODS Subjects submitted to renal transplantation between 1996 and 2011 who presented MGUS(More)
