Polyomavirus-Associated Nephropathy in Renal Transplantation: Interdisciplinary Analyses and Recommendations

Transplantation, 2005
Polyomavirus-associated nephropathy (PVAN) is an emerging cause of kidney transplant failure affecting 1-10% of patients. As uncertainty exists regarding risk factors, diagnosis, and intervention, an independent panel of experts reviewed the currently available evidence and prepared this report.

BK and JC polyomavirus co-infection resulting in polyomavirus nephropathy and progressive multifocal leukoencephalopathy at the same time, a case report

Brazilian Journal of Infectious Diseases
John Cunningham Virus (JCV) and BK Virus (BKV) are the most extensively studied Human Polyomaviruses (HPyVs), primarily associated with Progressive Multifocal Leukoencephalopathy (PML) and BKV Nephropathy (BKVN), respectively.

BK polyomavirus-associated nephropathy in kidney transplant [PDF]

Anales de la Facultad de Medicina, 2015
Two documented cases of BK polyomavirus-associated nephropathy (BKVN) seen at Hospital Edgardo Rebagliati Martins, EsSalud, Lima, Peru are reported. Final BKVN diagnosis was confirmed by renal biopsy and electron microscopy study. Case 1: Renal functional deterioration was not controlled despite reduction of immunosuppression and addition of antiviral ...

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

BK Polyomavirus-Associated Nephropathy Complicated by Life-Threatening Hemorrhagic Pericardial Effusion Following Immunosuppression Reduction in a Kidney Transplant Recipient: A Case Report. [PDF]

Case Rep Transplant
Background BK polyomavirus (BKPyV) is an opportunistic infection following kidney transplantation due to immunosuppression. It is a recognized cause of tubulitis and graft dysfunction in kidney transplant recipients (KTRs). Management is challenging because clinicians must balance viral control with the risk of acute rejection.

Polyomavirus Associated Nephropathy: Frequency and Graft Survival Analysis in Northeast of Iran. [PDF]

Iran J Pathol, 2021
Polyomavirus-associated nephropathy (PVAN), mainly caused by the BK virus, is one of the most important infectious complications of kidney transplantation. The leading histopathologic characteristics of PVAN is viral cytopathic effects, such as nucleomegaly with smudged or clumped chromatin and intranuclear ground-glass inclusion, mostly in tubular ...

Polyomavirus-associated nephropathy. [PDF]

World J Transplant, 2012
Polyomaviruses BK and JC are ubiquitous viruses with high seroprevalence rates in general population. Following primary infection, polyomaviruses BK and JC persist latently in different sites, particularly in the reno-urinary tract. Reactivation from latency may occur in normal subjects with asymptomatic viruria, while it can be associated to ...

Polyomavirus‐associated nephropathy: update in diagnosis [PDF]

Transplant Infectious Disease, 2006
Abstract: The histological diagnosis of BK or JC polyomavirus allograft nephritis (PVAN) requires evaluation of a renal biopsy with demonstration of the polyomavirus cytopathic changes and confirmation with an ancillary technique such as immunohistochemistry. Three histological patterns of PVAN (A, B, and C) are identified in renal biopsies. Pattern A
