High-Frequency US for BK Polyomavirus–associated Nephropathy after Kidney Transplant

Radiology, 2022
Background BK polyomavirus-associated nephropathy (BKPyVAN) is an important cause of chronic renal allograft dysfunction. However, US features indicative of BKPyVAN have not been fully evaluated. Purpose To assess the value of high-frequency US for the diagnosis of BKPyVAN in kidney transplant recipients.

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 ...

Polyomavirus‐associated nephropathy: update on BK virus‐specific immunity

Transplant Infectious Disease, 2006
Abstract: The human polyomavirus type 1, also called BK virus (BKV), causes polyomavirus‐associated nephropathy (PVAN) in 1–10% of renal transplant recipients, with graft loss in over 50% of cases. The risk factors for PVAN are not conclusively defined and likely involve complementing determinants of recipient, graft, and virus.

Ultrasound findings of BK polyomavirus-associated nephropathy in renal transplant patients

Journal of Nephrology, 2016
BK polyomavirus (BKV) is an emerging pathogen in immunocompromised patients. BKV infection occurs in 1-9 % of renal transplants and causes chronic nephropathy or graft loss. Diagnosis of BKV-associated nephropathy (BKVAN) is based on detection of viruria then viremia and at least a tubule-interstitial nephritis at renal biopsy. This paper describes the

An application of the 2018 Banff Classification for BK polyomavirus‐associated nephropathy in renal transplantation

Transplant Infectious Disease, 2021
AbstractBackgroundThere is still a lack of a recognized morphological classification of BK viral nephropathy (BKVN) which can better reflect the clinical manifestations and prognosis.MethodsWe retrospectively analyzed the data of 53 patients with BKVN in our center from January 2011 to December 2018 and evaluated the new Banff 2018 classifications ...

BK Polyomavirus‐associated nephropathy managed by screening policy in a real‐life setting

Transplant Infectious Disease, 2019
AbstractBackgroundBK polyomavirus‐associated nephropathy (PyVAN) is an important complication after kidney transplantation. Prevalence ranges from 1% to 10%, and graft loss occurs in approximately 50% of the cases. There is no effective treatment, so early viral detection with immunosuppression tapering is the current strategy to prevent PyVAN.AimsTo ...
