Urothelial Carcinoma of the Bladder Following BK Virus Infection in a Pediatric Kidney Transplant Recipient. [PDF]

open access: yesPediatr Transplant
ABSTRACT Background Urothelial bladder carcinoma is extremely rare in children and its association with BK virus infection remains unclear. Methods We describe the case of an 11‐year‐old girl who developed a urothelial carcinoma of the bladder four years after receiving her first kidney transplant.

BK Polyomavirus and Transformation [PDF]

open access: yesAmerican Journal of Transplantation, 2011
The human BK polyomavirus (PyV) (BKV) was isolated from the urine of a kidney transplant patient with the initials B.K. after cells with nuclear atypia were noted in the urine in the diagnostic workup of an alloureter stenosis. Electron microscopy revealed intranuclear inclusions of nonenveloped viral particles of 40–45-nm diameter suggesting infection

Cytomegalovirus and polyomavirus BK posttransplant [PDF]

open access: yesNephrology Dialysis Transplantation, 2007
Virus replication and progression to disease in transplant patients is determined by patient-, graft- and virus-specific factors. This complex interaction is modulated by the net state of immunosuppression and its impact on virus-specific cellular immunity.

Role of BK human polyomavirus in cancer [PDF]

open access: yesInfectious Agents and Cancer, 2018
Human polyomaviruses (HPyV), which are small DNA viruses classified into the polyomaviridae family, are widely distributed in human populations. Thirteen distinct HPyVs have been described to date. Some of these viruses have been found in human tumors, suggesting an etiological relationship with cancer.

BK Polyomavirus in Solid Organ Transplantation [PDF]

open access: yesAmerican Journal of Transplantation, 2013
The human BK polyomavirus (BKV) is the major cause of polyomavirus-associated nephropathy (PyVAN) putting 1-15% of kidney transplant patients at risk of premature allograft failure, but is less common in other solid organ transplants. Because effective antiviral therapies are lacking, screening kidney transplant patients for BKV replication in urine ...

The Agnogene of the Human Polyomavirus BK Is Expressed [PDF]

open access: yesJournal of Virology, 1998
ABSTRACT Primate polyomavirus genomes all contain an open reading frame at the 5′ end of the late coding region called the agnogene. A simian virus 40 agnoprotein with unknown functions has previously been demonstrated. We now show that a BK virus agnoprotein appears in the perinuclear area and cytoplasm late in the infectious cycle.

Optimized amplification of BK polyomavirus in urine

open access: yesJournal of Virological Methods, 2022
BK polyomavirus (BKPyV) is a ubiquitous pathogen that typically results in asymptomatic infection. However, in immunocompromised individuals, BKPyV viral shedding in the urine can reach 109 copies per mL. These high viral levels within urine provide ideal samples for next-generation sequencing to accurately determine BKPyV genotype and identify ...

BK polyomavirus nephropathy in two kidney transplant patients with distinct diagnostic strategies for BK virus and similar clinical outcomes: two case reports

open access: yesJournal of Medical Case Reports, 2017
Background BK polyomavirus-associated nephropathy is an important cause of post-transplantation renal failure. We present two cases of BK polyomavirus-associated nephropathy who were submitted to contrasting strategies of clinical follow-up to BK ...

Phylogenetic Analysis of Polyomavirus BK Sequences [PDF]

open access: yesJournal of Virology, 2006
ABSTRACT Polyomavirus BK (BKV) has emerged as an important pathogen in kidney transplant patients. Existing taxonomic classifications of BKV come from conventional DNA sequence alignments based on limited data derived from the VP1 gene. We have used a phylogenetic whole-genome approach to examine the pattern of diversity and evolutionary ...

The complete genome sequence BK polyomavirus study in kidney transplanted patients [PDF]

open access: yesJournal of Nephropathology, 2019
Background: BK polyomavirus is a member of the Polyomaviridae. This virus has spread worldwide and up to 82% of the world populations are serologically positive. BK polyomavirus usually transmits through inhalation or fecal-oral way in childhood, as well
