Infectivity of BK polyomavirus in hydrolyzed urine samples (E to I) measured over time. Initial infective virus concentrations in urine were 5 × 10 5 to 1 × 10 6 IU (infectious units) ml −1. Experiments were conducted until the detection limit was reached (3 × 10 2 IU ml −1). (A) Inactivation in different hydrolyzed urine samples.

Het Humaan polyomavirus 2, ook wel naar verwezen als het JC-virus of John Cunninghamvirus (JCV), is een menselijk polyomavirus (oude benaming: papovavirus) en is genetisch vergelijkbaar met het BK-virus en SV40.

cause of polyomavirus-associated nephropathy (Py-VAN) putting 1–15% of kidney transplant patients at risk of premature allograft failure, but is less com-mon in other solid organ transplants. Because effec-tive antiviral therapies are lacking, screening kidney transplant patients for BKV replication in urine and Clinical monitoring for polyomavirus infection is becoming common, but the optimal detection technique remains undefined. We compared the relative efficacy of exfoliative cytology and polymerase chain reaction (PCR) for detecting viruria in 100 urine samples. Definite decoy cells were seen in 8% and probable decoy cells in 5% of specimens. 2016-08-12 · Human Polyomaviruses (HPyVs) are small, non-enveloped double-stranded DNA viruses. They are found in urine, feces and wastewater as a result are used as sewage source tracking viruses and are emerging as potential environmentally related transmission of viral induced cancer. These viruses had previously been classified as belonging to a single family: Papovaviridae (Papillomaviruses Polyomavirus BK is widely present in healthy individuals, but latent in kidneys, central nervous system and B cells Other polyoma viruses are JC (causes progressive multifocal leukencephalopathy) and SV40 (causes subclinical infections) All patients with BKN shed abundant polyomavirus inclusion bearing ‘decoy cells’ in the urine.

Has been associated with interstitial nephritis and obstruction of the ureteral lumen; may be   High viral DNA copy numbers in the urine or plasma can act as a surrogate marker of BK virus nephropathy.

Pyuria is defined by the presence of white blood cells in the urine and is usually followed by bacteria, which may be addressed through the underlying cause.

The inclusion bearing cells are easily identified and quantifiable in routine Papanicolaou stained urine cytology specimens. 2012-08-01 · The viropathic change of a ‘decoy cell’ signifying what was later discovered to be a polyomavirus infection (generally BK, although JC virus can cause similar changes) was first well-described by the cytotechnologist Andrew Ricci in the 1950s at Memorial Sloan Kettering Cancer Center. 23 Initially important as a ‘pitfall’ in the differential diagnosis of urothelial carcinoma, with increasing numbers of renal transplants decoy cells became a more common finding in the urine 2005-04-27 · Clinical monitoring for polyomavirus infection is becoming common, but the optimal detection technique remains undefined.

For accurate monitoring of BK polyomavirus (BKV) in transplant patients Roche receives first FDA clearance for urine sample type for BK virus quantitative test 

Polyomavirus nephritis and hemorrhagic cystitis. Demonstration of the characteristic “decoy” cells by cytologic testing of urine is suggestive of viruria with polyomaviruses. Decoy cells are epithelial cells with enlarged nuclei and large basophilic ground-glass intranuclear inclusions. Primary infection of Polyomavirus BK generally occurs in childhood without evident symptoms and the virus can remain latent in the urinary tract. BK polyomavirus is one of the common post-transplant viral infections, affecting ∼15% of renal transplantation recipients (RTR), leading to graft loss in more than half of cases Plasma and urine Polyomavirus-Haufen were counted in 40 urine samples from patients with biopsy-proven definitive PVN. The number of PV-Haufen was correlated with both histologic PVN disease grades 1 to 3 and the number of SV40-T–expressing cells as indicators of intrarenal PV replication in corresponding renal allograft biopsies (manual counts and automated morphometry).

Jamin Brahmbhatt, MD, is board-certified in urology. He is an assistant professor at UCF …stent – Urinary stents may increase the likelihood of urinary tract infection, BK ( polyomavirus) viremia, and BK (polyomavirus)-sustained viremia or may  10 Aug 2020 BK polyomavirus (BKPyV) is a small DNA virus that establishes BK polyomavirus in the urine for follow-up of kidney transplant recipients. Your molecular genetic test system for quantitative detection of polyomavirus BK from EDTA plasma and urine.

This study was undertaken to determine the significance of polyomavirus nuclear inclusions in urine cytology specimens. Thirty‐two such cases were identified and patient follow‐up was instituted. We have determined that there is no detectable urologic damage in such patients. In a minority of cases inclusions were found in subsequent urines but they ultimately disappeared within 3 mo. In a Polyomavirus infections are common in the general (adult) population with a reported prevalence of more than 80%.

Behandling och prevention Ett flertal nukleosidanaloger har använts, men ofta i små serier eller utan säkra resultat. Framgångsrik behandling av It has been suggested that this virus may be transmitted through respiratory fluids or urine, since infected individuals periodically excrete virus in the urine. A survey of 400 healthy blood donors was reported as showing that 82% were positive for IgG against BK virus.
