BK polyomavirus-associated nephropathy [PDF]

Childhood Kidney Diseases, 2022
BK polyomavirus (BKPyV) is a ubiquitous virus residing in the kidney tubules and is clinically significant only in immunocompromised patients. In clinical practice, BKPyV is a causative pathogen of BKPyV-associated nephropathy (BKVAN) in kidney allograft

BK Polyomavirus-associated nephropathy - diagnostic and treatment standard. [PDF]

Nephrol Dial Transplant
ABSTRACT BK polyomavirus (BKPyV) is recognized as a significant viral complication of kidney transplantation. Prompt immunosuppression reduction reduces early graft failure rates due to BK polyomavirus-associated nephropathy (BKPyVAN), however, modulation of immunosuppression can lead to acute rejection.

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

Journal 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 ...

Leflunomide and Polyomavirus-Associated Nephropathy in Renal Transplant [PDF]

, 2009
Polyomavirus nephropathy is a major complication in renal transplantation, associated with renal allograft loss in 14 to 80% of cases. There is no established treatment, although improvement has been reported with a variety of approaches. The authors report two cases of polyomavirus infection in renal allograft recipients.

BK Polyomavirus-Associated Nephropathy and Hemorrhagic Cystitis in Transplant Recipients—What We Understand and What Remains Unclear [PDF]

Viruses
The reactivation of BK polyomavirus (BKPyV) during severe immunosuppression plays a crucial role in two significant syndromes observed in transplant recipients: BK polyomavirus-associated nephropathy (BKPyVAN) in kidney transplant patients and BK ...

BK polyomavirus microRNA expression and sequence variation in polyomavirus-associated nephropathy [PDF]

Journal of Clinical Virology, 2018
BK polyomavirus (BKPyV) infection is a common asymptomatic viral infection in the general population. Severe complications are seen in immunocompromised individuals, such as polyomavirus-associated nephropathy (PyVAN) in renal transplant recipients. Information on BKPyV microRNA expressions is scarce, although polyomavirus-encoded microRNAs have been ...

Polyomavirus – an emergent pathogen in transplant recipients [PDF]

Einstein (São Paulo), 2007
Medical centers that work with transplants often face opportunisticinfections that demand specific tools to make diagnosis. Theprevalence of latent polyomavirus infections is high, and the mostcommon site of latency of the most prevalent polyomavirus in ...

Cellular immunity in BK polyomavirus associated nephropathy following adult kidney transplantation

Transplantation Reports, 2022
Background: BK polyomavirus (BKPyV) is the most important polyomavirus affecting renal transplant recipients. BKPyV associated nephropathy (BKVAN) is seen in about 5% of renal transplant patients and can lead to graft loss in up to 50% of cases ...

BK Polyomavirus-specific T cell immune responses in kidney transplant recipients diagnosed with BK Polyomavirus-associated nephropathy [PDF]

BMC Infectious Diseases, 2019
Background Adjustment of immunosuppression is the main therapy for BK polyomavirus (BKPyV)-associated nephropathy (BKPyVAN) after kidney transplantation (KT). Studies of BKPyV-specific T cell immune response are scarce.

Polyomavirus specific cellular immunity: from BK-virus-specific cellular immunity to BK-virus-associated nephropathy ? [PDF]

Frontiers in Immunology, 2015
In renal transplantation, BK-virus-associated nephropathy has emerged as a major complication, with a prevalence of 5–10% and graft loss in >50% of cases. BK-virus is a member of the Polyomavirus family and rarely induces apparent clinical disease in the
