BK-virus är ett dubbelsträngat DNA-virus med cirkulärt genom som tillhör familjen polyomavirus.Viruset sprids från människa till människa, men exakt hur det sprids är ännu inte känt. Både luftvägarna och mag- och tarmkanalen har föreslagits som möjliga ingångar för viruset. Genomet är till 75 % identiskt med JC-virus och upptäcktes samtidigt som detta 1971 The BK virus is a member of the polyomavirus family. Past infection with the BK virus is widespread, but significant consequences of infection are uncommon, with the exception of the immunocompromised and the immunosuppressed.BK virus is an abbreviation of the name of the first patient whom the virus was isolated from in 1971 (the patient was then 29 years old) BK-virus (BKV) infektion är vanligt förekommande, och i vuxen ålder har mer än 80% antikroppar mot BKV. Efter den primära infektionen, som oftast är subklinisk, finns virus kvar latent, framför allt i njurens tubulusceller. Vid immunsuppression kan BKV reaktiveras och orsaka inflammation i njurar och urinvägar
BK VIRUS. The BK virus was first isolated from the urine of a renal transplant recipient with ureteric stenosis in 1971 , but it was not until 20 years later that BK was recognized as a cause of interstitial nephritis and allograft failure in renal transplant recipients [2, 3] Arthur RR, Shah KV, Charache P, Saral R.

BK virus asymptomatic primary infection occurs early in life, with seroprevalence reaching more than 50% at 10 years of age and to up to 90% in adults. BK virus resides in the kidneys. Low levels of replication are asymptomatic and result in BK viruria in 5% of healthy individuals . The BK virus may be spread if you have contact with infected blood or body fluids, such as saliva (spit). It can spread from one person to another during an organ transplant or from a mother to her baby during birth BK virus Infectious disease A small human polyomavirus which, like the JC virus, can transform infected cells in culture; 1º BKV infection is usually subclinical, is most common in early childhood, persists in renal epithelium and may be reactivated, causing severe tubulointerstitial nephritis, and cystitis in BM transplant recipients, or in the immunocompromised Pts-eg, those with hyper. BK virus nephropathy (BKVN) was first described in a renal transplant recipient (RTR) presenting with transplant ureteric stenosis and was named after the initials of the patient. 1 After a quarter century, BKVN was increasingly recognized to result in allograft kidney damage, with the background of more potent immunosuppressive regimens. BKVN occurs in up to 10% of RTR and can result in graft.
BK virus nephropathy is a serious complication of kidney transplantation. Although 10%-30% of kidney recipients have BK viremia, nephropathy occurs in approximately 2% ().

History. BK virus is a human polyomavirus belonging to the family Papovaviridae. The other member of the Papovaviridae family is the Papillomavirus genus. The polyoma genus was named after the murine polyoma virus that caused tumors in newborn mice .Polyomaviruses are ubiquitous in nature and are species-specific, including humans (JC virus [JCV], BK virus), monkeys (simian virus 40 [SV40. Other possible associations - BK virus was associated with cases of acute haemorrhagic cystitis following bone marrow transplantation. However, it is possible that two independent but synchronous events may be taking place - reactivation of BKV and haemorrhagic cystitis. The genomes of JC and BK virus were. BK virus, a relative of JC virus, which is the etiologic agent of progressive multifocal leukoencephalopathy (PML), was first isolated in 1971 from a urine sample obtained from a renal transplant recipient .The name of the virus refers to the first patient's initials, which is also true of JC virus .This member of the polyoma subgroup of papovaviruses, which includes BK virus, JC virus. BK virus infection remains asymptomatic for a long time. But BK virus infection after kidney transplant can harm the patient due to reduction in immunity with potent immunosuppressive agents BK virus has also been detected in tissue specimens from a variety of neoplasms. We believe that BK virus is most often permissively present in sites of disease in immunosuppressed patients, rather than being an etiologic agent that causes symptoms or pathologic findings

This single-center retrospective cohort study describes the evolution of BK virus allograft nephropathy (BKVAN) from 63 kidneys (from 61 patients) using sequential histopathology (454 biopsies, averaging 7.8 ± 2.6 p BK virus is a polyomavirus in the same family of viruses as JC virus and has become recognized as an important causal infectious agent in complications after kidney transplant and hematopoietic cell transplant (HCT)
Nephropathy from BK virus (BKV) infection is an evolving challenge in kidney transplant recipients. It is the consequence of modern potent immunosuppression aimed at reducing acute rejection and improving allograft survival. Untreated BKV infections lead to kidney allograft dysfunction or loss. Decreased immunosuppression is the principle treatment but predisposes to acute and chronic rejection Overview. Cytomegalovirus (CMV) is a common virus. Once infected, your body retains the virus for life. Most people don't know they have CMV because it rarely causes problems in healthy people.. If you're pregnant or if your immune system is weakened, CMV is cause for concern. Women who develop an active CMV infection during pregnancy can pass the virus to their babies, who might then.

Depending on the population, varying percentages of patients may be found to be positive BK-virus (BKV) is commonly found in the human population. Serologic evidence of infection is present in approximately 90% by adolescence. In the majority of healthy individuals the virus does not induce any specific symptoms but a persistent infection is established. However, in immunosuppressed patients the virus may be an important pathogen
BK virus, or BKV, is a mosquito borne virus that's named after the initials of the patient in whom the virus was first identified. BK virus typically infects the urinary system of immunocompromised individuals, or those with a weakened immune system, especially those receiving immunosuppressive medications following organ transplants BK virus-associated nephropathy (BKVAN) is associated with allograft dysfunction and graft failure in kidney transplant recipients. Reduction of immunosuppression is the gold standard of treatment for BKVAN, possibly increasing the risk for acute rejection BK virus is rarely known to cause a disease, but is typically associated with patients who have had a kidney transplant. However, many people who are infected with the BK virus do not show any symptoms. And in case the symptoms do appear, they are mild, such as a respiratory infection or fever
The incidence of BK virus infection in kidney transplant recipients has increased over recent decades, coincident with the use of more potent immunosuppression. More importantly, posttransplant BK virus replication has emerged as an important cause of graft damage and subsequent graft loss. Immunosuppression has been accepted as a major risk for BK virus replication BK Virus R-GENE ® advantages. BK virus has been identified as an important pathogen in interstitial nephropathy in kidney transplant patients (which could leads to organ rejection) and hemorrhagic cystitis in hematopoietic stem cell transplant patients.Due to these concerns, optimized detection and monitoring of BK virus infection is important. BK Virus R-GENE ® is an ideal solution. BK-virus associated hemorrhagic cystitis (HC) is a condition causing significant suffering for those patients developing severe symptoms and it is difficult to manage since there is no proven effective strategy either to prevent or to treat the condition The BK virus is a member of the polyomavirus family. Past infection with the BK virus is widespread, but significant consequences of infection are uncommon. The BK virus was first recognized from a renal transplant patient. This BK virus is similar to another virus called the JCV since their genome sequence share 75% homology BK Virus DNA, Quantitative, Real-Time PCR, CSF - This test is used to determine the presence of BK Virus DNA in patients specimens. Detection of the virus in these specimens may be indicative of an active infection, as PCF detects the presence of the virus, and not the hosts reaction to the virus.
