av A Lundstig · 2007 — BKV is mainly related to urinary tract diseases and JCV is the causative agent of progressive multifocal leukoencephalopathy (PML). The human polyomaviruses

A morphologic sign of the (re) activation of polyomaviruses is the detection of typical intranuclear viral inclusion bearing epithelial cells, so-called “decoy cells”, in the urine. Decoy cells often contain polyoma-BK-viruses.

BK Polyomavirus Nephropathy is usually not caused by administration of a single immunosuppressant medication, but is related to overall immunosuppressive load. BK polyomavirus (BKPyV) has been associated with some high-grade and special urothelial cell carcinoma (UCC) subtypes in immunosuppressed patients. Here, we evaluated the relationship of BKPyV-positive urine cytology specimens (UCS) with UCC. A large single-institution database was retrospectively searched for UCS positive for decoy cells, suggesting BKPyV infection. These were tested for the Se hela listan på de.wikipedia.org Diagnosis of polyomavirus BK nephropathy and treatment by low-dose immunosuppression may be optimized by using surrogate markers, such as the detection of viral inclusion bearing cells in the urine and polyomavirus BK DNA in plasma by polymerase chain reaction. These markers were used prospectively in the management of a 44-year-old woman and led to the diagnosis of polyomavirus BK nephropathy INTRODUCTION. Polyomavirus infections have been detected in vertebrate hosts including rodents, cattle, birds, monkeys, and primates.

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

Methods We have investigated in 50 healthy subjects whether jcv-miR-J1-5p (and its variant jcv-miR-J1a-5p) can 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) Se hela listan på talk.ictvonline.org The cytology of urine in human polyomavirus infection is quite characteristic. The inclusion-bearing cells have a characteristic appearance and are often present in large numbers. Electron Microscopy of the urinary sediment after centrifugation at 20000 may reveal the presence of polyomavirus particles. Urine cytopathology is a large part of cytopathology..

Murine polyomavirus was the first polyomavirus discovered, having been reported by Ludwik Gross in 1953 as an extract of mouse leukemias capable of inducing parotid gland tumors. Polyomaviridae-Wikipedia

OBJECTIVES: After kidney transplantation, human BK polyomavirus (BKPyV) can induce a progressive disease, in three stages: viruria, viraemia, and then nephropathy after a few months of viral replication. Therapeutic intervention is recommended when BKPyV is detected in the plasma. Two polyomaviruses, BK virus (BKV) and JC virus (JCV), are ubiquitous in the human population, generally infecting children asymptomatically and then persisting in renal tissue. It is generally thought that reactivation leads to productive infection for both viruses, with progeny shed in the urine. The reactivation of polyomavirus in the kidneys and urinary tract causes the shedding of infected cells, virions, and/or viral proteins in the urine. This allows urine cytology to examine these cells, which if there is polyomavirus inclusion of the nucleus, is diagnostic of infection. [74] Polyomavirus lämpar sig väl för PCR-diagnostik.

While creatinine itself is caused by muscle metabolism, its presence in urine indicates how well the kidneys are functioning. Your doctor may want to A healthy bladder can hold up to 16 ounces of urine for 2 to 5 hours. If this isn't the norm, read about the problems it may be attributed to.

Background: According to The Paris System for Reporting Urinary Cytology (TPS), the category of atypical urothelial cells (AUC) should not be applied to specimens in which cellular changes can be entirely attributed to the polyoma (BK) virus cytopathic effect (CPE). Until recently, cases with BK CPE at The Johns Hopkins Hospital were categorized as atypical urothelial cells of uncertain significance (AUC-US), which is equivalent to the TPS AUC category. PV viruria was associated primarily with JCV, rather than BKV. PV viruria, including JCV viruria, correlated with urine decoy cells and increased age.

BK Polyomavirus Nephropathy usually occurs with the use of immunosuppressant medications like Tacrolimus and mycophenolate mofetil. BK Polyomavirus Nephropathy is usually not caused by administration of a single immunosuppressant medication, but is related to overall immunosuppressive load.

All patients with BKN shed abundant polyomavirus inclusion bearing ‘decoy cells’ in the urine. They can be easily detected in standard Papanicolaou‐stained cytology preparations or – with some expertise – also in the urine sediment by phase contrast microscopy [ 12 , 13 , 21 , 28 , 31 , 41 , 73 , 75 , 82 , 95 - 97 ]. 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.
