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 polyomaviruses and cancer: an overview

Clinics; 73 (supl.1), 2018
The name of the family Polyomaviridae, derives from the early observation that cells infected with murine polyomavirus induced multiple (poly) tumors (omas) in immunocompromised mice. Subsequent studies showed that many members of this family exhibit the capacity of mediating cell transformation and tumo...

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...

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...
