BKTyper: Free Online Tool for Polyoma BK Virus VP1 and NCCR Typing

Viruses, 2020
Human BK polyomavirus (BKPyV) prevalence has been increasing due to the introduction of more potent immunosuppressive agents in transplant recipients, and its clinical interest. BKPyV has been linked mostly to polyomavirus-associated hemorrhagic cystitis,

Full‐House Nephropathy Without Lupus Manifesting During Acute Kidney Allograft Rejection: A Case Report

Clinical Case Reports, Volume 14, Issue 1, January 2026.
ABSTRACT Kidney transplantation increases the survival rate of end‐stage renal disease patients; however, acute rejection and glomerulonephritis, such as the uncommon non‐lupus full‐house nephropathy (NLFHN), can lead to graft dysfunction. NLFHN exhibits a characteristic lupus immunofluorescence pattern in the absence of systemic lupus features, which ...

Polyomavirus BK Nephropathy-Associated Transcriptomic Signatures: A Critical Reevaluation

Transplantation Direct, 2018
Background. Recent work using DNA microarrays has suggested that genes related to DNA replication, RNA polymerase assembly, and pathogen recognition receptors can serve as surrogate tissue biomarkers for polyomavirus BK nephropathy (BKPyVN). Methods.

Proteinuria After Kidney Transplantation

Pediatric Transplantation, Volume 29, Issue 8, December 2025.
ABSTRACT Proteinuria is a relatively frequent complication in both adults and children after kidney transplantation (40%–80%). It is usually mild and predominantly of tubular origin and is caused mainly by rejection, mTOR inhibitors, or hypertension; however, proteinuria could also be in the nephrotic range and of glomerular origin if caused by the ...

Renal Allograft Biopsies with Polyomavirus BK Nephropathy: Turin Transplant Center, 2015–19

Viruses, 2020
Background: In kidney transplant patients, polyomavirus-associated nephropathy (PVAN) represents a serious complication; the key factor for the development of PVAN is immunosuppression level and modulation of anti-rejection treatment represents the first

Human Polyomavirus BK Genome Analysis in BKPyV Induced Rodent Cell Lines

MicrobiologyOpen, Volume 14, Issue 5, October 2025.
In this study, we analyzed the BK polyomavirus (BKPyV) genome derived from three rodent cell lines established from BKPyV induced tumors. BKPyV derived one cell line had a large deletion. The noncoding control region (NCCR) of BKPyV derived from these cell lines had the same structure as viruses induced tumors.

Frequency of Polyomavirus BK Infection in Kidney Transplant Patients Suspected to Nephropathy

International Journal of Organ Transplantation Medicine, 2015
Background: Polyomavirus BK is a major cause of nephropathy in immunosuppressed transplanted patients. Non-invasive diagnostic protocols such as molecular detection of polyomavirus BK replication are a useful strategy to predict BK virus-associated ...
