Caracterización clínica de la Nefropatía por Poliomavirus BK en pacientes trasplantados renales
Clinical characterization of Polyomavirus BK nephropathy in kidney transplanted patients

Cambios rev. méd; 22 (2), 2023; 22 (2), 2023; 22 (2), 2023
INTRODUCCIÓN. La nefropatía por poliomavirus BK resulta un problema emergente en el trasplante renal, pues contribuye a la pérdida temprana de los injertos renales. OBJETIVO. Caracterizar clínicamente a los pacientes trasplantados renales con nefropatía por poliomavirus BK. MATERIALES Y MÉTODOS. Es...

Modeling of covariates predicting renal allograft failure within six months after transplantation

ABCS health sci; 47 (), 2022
INTRODUCTION: Kidney transplantation (KT) is the renal replacement therapy (RRT) of choice for patients with chronic kidney disease (CKD). However, not every KT is successful and some patients persist on RRT. OBJECTIVE: To model a logistic regression with pre- and post-KT risk covariates capable of predi...

Outpatient haploidentical hematopoietic stem cell transplant using post-transplant cyclophosphamide and incidence of hemorrhagic cystitis

Abstract Introduction Hemorrhagic cystitis (HC) is a common complication of haploidentical hematopoietic stem cell transplantation (haplo-HSCT), characterized by irritative symptoms of the urinary tract and a higher morbidity and mortality rate. The worldwide incidence is reported between 10% and 70%. T...

Polyomaviruses BK and JC DNA infection in peripheral blood cells from blood donors

Braz. j. infect. dis; 23 (1), 2019
ABSTRACT Objectives: To investigate the prevalence of human polyomavirus (BK and JC viruses) infection in peripheral blood mononuclear cells of healthy blood donors. Methods: The study included 250 healthy blood donors. Five-milliliter blood was drawn into sterile EDTA tubes and PBMCs were isolated fro...

BK virus salivary shedding and viremia in renal transplant recipients

J. appl. oral sci; 27 (), 2019
Abstract Objectives: This study aimed to verify the presence of polyomavirus BK (BKPyV) in the saliva of kidney transplant recipients and to correlate it with blood viremia. Material and Methods: We have conducted a cross-sectional study with a sample involving 126 renal transplant recipients. 126 samp...

Quantitative detection of BK virus in kidney transplant recipients: a prospective validation study

J. bras. nefrol; 40 (1), 2018
Abstract Introduction: BK virus (BKV) infection in renal transplant patients may cause kidney allograft dysfunction and graft loss. Accurate determination of BKV viral load is critical to prevent BKV-associated nephropathy (BKVAN) but the cut-off that best predicts BKVAN remains controversial. Objectiv...

Human polyomavirus infection: Cytological and molecular diagnosis

Summary Few studies directly compare urinary cytology with molecular methods for detecting BK and JC polyomaviruses. Reactivation of BKV infection is the main risk factor for the development of nephropathy in immunocompromised individuals. The limitation of the cytological method can be attributed to the...

Distribution and genetic diversity of the human polyomaviruses JC and BK in surface water and sewage treatment plant during 2009 in Porto Alegre, Southern Brazil

Braz. j. biol; 77 (3), 2017
Abstract The human polyomaviruses JC and BK (JCPyV and BKPyV) are ubiquitous, species-specific viruses that belong to the family Polyomaviridae. These viruses are known to be excreted in human urine, and they are potential indicators of human wastewater contamination. In order to assess the distribution ...

Evaluation of the predisposition and clinical impact of BK virus replication in kidney transplant patients

An. acad. bras. ciênc; 89 (1,supl), 2017
ABSTRACT The BK virus (BKV) produces a subclinical kidney infection in immunocompetent individuals. However, viremia may occur in kidney transplant patients with ongoing immunosuppression. BKV-associated nephropathy (BKVN) has no specific treatment and is a leading cause of organ transplant loss. In this...
