Redução de hemoglobina: risco para lesão renal aguda após revascularização do miocárdio

Objetivo: verificar se a redução da taxa de hemoglobina no pós-operatório de revascularização do miocárdio interfere na função renal dos pacientes. Método: estudo observacional e prospectivo, desenvolvido entre fevereiro e junho de 2016, com 51 pacientes que realizaram cirurgia de revasculariza...

Acetaminophen induces alterations to the renal tubular ultrastructure in a rat model of acute nephrotoxicity protected by resveratrol and quercetin

Int. j. morphol; 38 (3), 2020
Acetaminophen (also called paracetamol, or APAP) induced nephrotoxicity is reported after accidental or intentional ingestion of an overdose of the drug. Renal tubular ultrastructural alterations induced by APAP overdose associated with the induction of biomarkers of kidney injury have not been investiga...

Urine microscopy as a biomarker of Acute Kidney Injury following cardiac surgery with cardiopulmonary bypass

J. bras. nefrol; 42 (1), 2020
Abstract Introduction: Acute kidney injury (AKI) occurs in about 22% of the patients undergoing cardiac surgery and 2.3% requires renal replacement therapy (RRT). The current diagnostic criteria for AKI by increased serum creatinine levels have limitations and new biomarkers are being tested. Urine sedi...

Mast cells in the kidney biopsies of pediatric patients with lupus nephritis

J. bras. nefrol; 42 (1), 2020
ABSTRACT Introduction: Mast cells may be involved in inflammation and contribute to the onset of fibrosis in lupus nephritis (LN). Objective: This study aimed to correlate the presence of mast cells in kidney biopsy specimens of pediatric patients with LN with activity (AI) and chronicity (CI) indice...

Treatment of chronic hepatitis C in patients with chronic kidney disease with Sofosbuvir-basead regimes

Braz. j. infect. dis; 24 (1), 2020
ABSTRACT Background: To analyze the effectiveness and the safety of Sofosbuvir-based regimens to treat patients with chronic hepatitis C virus (HCV) infection and chronic kidney disease (CKD). Methods: A retrospective, observational study in patients with chronic HCV infection and CKD treated with Sofo...

Renal changes and acute kidney injury in covid-19: a systematic review

Rev Assoc Med Bras (1992); 66 (Suppl 2), 2020
SUMMARY OBJECTIVE We aimed to present a review of renal changes in patients with COVID-19. METHODS We performed a systematic review of the literature to identify original articles regarding clinical, laboratory, and anatomopathological kidney changes in patients infected with SARS-CoV-2 published unt...

Kidney transplantation with donors in severe acute kidney injury. Should we use these organs? Retrospective Case Series

J. bras. nefrol; 41 (4), 2019
ABSTRACT Introduction: The number of incident and prevalent patients on dialysis has increased, as well as the number of candidates for renal transplantation in Brazil, without a proportional increase in the number of organ donors. The use of expanded kidneys, as to renal function, may be an alternative...

Zinc alpha 2 glycoprotein as an early biomarker of diabetic nephropathy in patients with type 2 diabetes mellitus

J. bras. nefrol; 41 (4), 2019
Abstract Introduction: Although microalbuminuria remains the gold standard for early detection of diabetic nephropathy (DN), it is not a sufficiently accurate predictor of DN risk. Thus, new biomarkers that would help to predict DN risk earlier and possibly prevent the occurrence of end-stage kidney dis...

Is hypoalbuminemia a predictor for acute kidney injury after coronary bypass grafting in diabetes mellitus patients?

Abstract Objective: Acute kidney injury (AKI) is one of the most important complications after coronary artery bypass grafting (CABG) procedure. Serum albumin, which is an acute phase reactant, is suggested to be associated with AKI development subsequent to various surgical procedures. In this study, w...
