Most cells physiologically release vesicles as way of intercellular communication. The so-called Extracellular Vesicles (EVs) include exosomes, ectosomes, and apoptotic bodies, which basically differ in their composition and subcellular origin. Specifically, EVs found in urine reflect the state of the urinary system, from podocytes to renal-tubular cells,(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)
Data on dolutegravir removal by hemodialysis are lacking. To study this, we measured dolutegravir plasma concentrations in samples of blood entering and leaving the dialyzer and of the resulting dialysate from 5 HIV-infected patients with end-stage renal disease. The median dolutegravir hemodialysis extraction ratio was 7%. The dolutegravir concentrations(More)
AIMS No long-term studies of renal function evolution in morbidly obese (MO) patients after weight loss are available. The aim of our work was to ascertain the long-term influence of drastic weight reduction on renal function in MO patients with obesity-related glomerular lesions. METHODS 92 MO patients with normal renal function and biopsy evidence of(More)
Renal biopsy is the gold-standard procedure to diagnose most of renal pathologies. However, this invasive method is of limited repeatability and often describes an irreversible renal damage. Urine is an easily accessible fluid and urinary extracellular vesicles (EVs) may be ideal to describe new biomarkers associated with renal pathologies. Several methods(More)
Patients with chronic kidney disease (CKD) are characterized by a state of inflammation and oxidative stress that seems to improve after kidney transplantation (KT). Nevertheless, there is controversy regarding what is the best marker that better define inflammation and specially oxidative stress. To evaluate the biomarkers which are associated with(More)
INTRODUCTION IGF-1 (insulin-like growth factor-1) is a hormone involved in cell growth and other important processes. In the kidney, IGF-1 has a stimulating effect, increasing the blood flow and glomerular filtration rate. Although many experimental animal studies regarding the role of IGF-1 in the kidney have been conducted, few human studies are available(More)
Cholesterol-crystal embolization (CE) usually presents as an acute or subacute multisystemic disease. When affecting native kidneys prognosis is poor, often leading to chronic kidney disease. Presentation in renal allografts is a rare condition although probably underdiagnosed. If renal CE originates from the recipient, allograft survival is usually good,(More)
BACKGROUND Post-transplant recurrent glomerulonephritis (RGN) is the third cause of graft failure in the first year after renal transplantation (RT). The purpose of this study was to analyze the incidence of RGN, clinical presentation, and clinical evolution of transplanted renal graft in patients who underwent RT at our center. METHODS We studied(More)
BACKGROUND Some lesions not included in the Banff classification, such as inflammation in the scarred areas and total inflammation, have been described to have prognostic value in the evaluation of graft biopsies. Our aim was to reassess kidney graft biopsies and study the impact of histopathologic lesions, both those graded in the Banff classification and(More)
