The value and complexity of studying cellular immunity against BK Polyomavirus in kidney transplant recipients.

Journal of Clinical Virology
BK Polyomavirus is of particular concern for kidney transplant recipients, due to their immunosuppression. This problem is exacerbated by the high effectiveness of antirejection therapies, which also compromise the organism's ability to fight viral ...

Detection of BK polyomavirus genotypes to predict the development of BK polyomavirus‐associated complications in kidney transplant recipients: A retrospective analysis

Transplant Infectious Disease, 2021
This study focused on the role that BK polyomavirus (BKPyV) genotypes can play in the development of BKPyV‐associated complications in renal transplant recipients.

Belatacept‐based immunosuppression does not confer increased risk of BK polyomavirus‐DNAemia relative to tacrolimus‐based immunosuppression

Transplant Infectious Disease
The effect of belatacept on BK polyomavirus (BKPyV) control remains largely unknown.

BK-Polyomavirus-Reaktivierung nach Nierentransplantation

Der Nephrologe, 2016
Die BK-Polyomavirus(BKPyV)-Reaktivierung nach Nierentransplantation fuhrt bei bis zu 10 % der transplantierten Patienten zu einer polyomavirusassoziierten Nephropathie (PyVAN), von denen bis zu 50 % einen Transplantatverlust erleiden. Der Hauptrisikofaktor der BKPyV-Reaktivierung ist die immunsuppressive Therapie durch einerseits die immunsuppressive ...

BK Polyomavirus Diversity After Hematopoietic Stem Cell Transplantation

The Journal of Infectious Diseases, 2023
Abstract BK polyomavirus (BKPyV) infection is common after hematopoietic stem cell transplantation (HSCT) and is associated with the development of hemorrhagic cystitis (HC). The role that BKPyV plays in the pathogenesis of HC is not well characterized.

Polyomavirus BK infection in Greek renal transplant recipients

Transplantation Proceedings, 2004
BK polyoma virus associated nephropathy is increasingly recognized as an important cause of allograft dysfunction among renal transplant recipients. Herein we present the cases of two renal transplant recipients who developed progressive functional deterioration suspicious for BK polyoma virus involvement.

BK Polyomavirus microRNA in Kidney Transplant Recipient

Transplantation Proceedings
BK polyomavirus-associated nephropathy (PyVAN) remains a serious threat for renal dysfunction and graft loss in kidney transplant recipients on immunosuppressive medication. In this study, a pilot cohort of 16 kidney transplant recipients were recruited of which eight were with significant BKPV viremia (sBKPV) and the rest were controls matched to age,

Granulomatous inflammation in BK polyomavirus–associated nephropathy

Transplant Infectious Disease, 2018
AbstractEvolving BK polyomavirus–associated nephropathy (BKPyVAN) is characterized by tubulointerstitial inflammation that closely resembles acute T‐cell–mediated allograft rejection if tubulitis is significant. The cellular composition of the inflammation varies during the course of BKPyVAN, and clusters of plasma cells may herald resolution of the ...

BK polyomavirus-specific antibody and T-cell responses in kidney transplantation: update.

Current Opinion in Infectious Diseases, 2019
PURPOSE OF REVIEW BK polyomavirus (BKPyV) has emerged as a significant cause of premature graft failure after kidney transplantation. Without effective antiviral drugs, treatment is based on reducing immunosuppression to regain immune control over BKPyV ...
