Aryl hydrocarbon receptor expression by macrophages and lymphocytes within infiltrates in BK polyomavirus associated nephropathy

Transplant Immunology, 2018
BK virus nephropathy (BKPyVN) is a major complication after renal transplantation. Little is known about the intra renal immune response during BKPyVN. The role of macrophages remains elusive. The activation of aryl hydrocarbon receptor (AHR) - a transcription factor involved in drug metabolism - plays a key role in inflammation and viral tolerance ...

Polyomavirus Associated Trichodysplasia Spinulosa in a Pediatric Kidney Transplant Recipient

Pediatric Transplantation, Volume 29, Issue 5, August 2025.
ABSTRACT Background Trichodysplasia spinulosa (TS) is an inconspicuous cutaneous infection caused by a distinct polyoma virus affecting the immunocompromised host. TS is rare in children and can masquerade as other dermatological conditions, causing a delay in diagnosis.

Production of recombinant VP1-derived virus-like particles from novel human polyomaviruses in yeast [PDF]

, 2015
Background: Eleven new human polyomaviruses (HPyVs) have been identified in the last decade. Serological studies show that these novel HPyVs sub-clinically infect humans at an early age.

A Rare Case of Parvovirus Infection Causing Pure Red Cell Aplasia in a Kidney‐Pancreas Transplant Recipient

Nephrology, Volume 30, Issue 7, July 2025.
ABSTRACT Parvovirus B19 infection can rarely manifest with pure red cell aplasia in immunocompromised hosts. This case details a 48‐year‐old male, 11 years post kidney‐pancreas transplant who was admitted with a chronic normocytic anaemia (haemoglobin 72 g/L) after being admitted four months prior with a bleeding peptic ulcer, requiring eight units of ...

The Value of Urinary Decoy Cells Finding in Patients with Kidney Transplantation [PDF]

, 2010
Childhood infection with polyomaviruses leads to a life-long latent infection of renal and urinary tract epithelia. Replication in the reno-urinary epithelium is associated with viral cytopathic changes such as nuclear inclusions and decoy cells.

Multiplex detection in tonsillar tissue of all known human polyomaviruses [PDF]

, 2017
Background: In the past few years, eleven new human viruses have joined the two previously known members JCPyV and BKPyV of the Polyomaviridae family, by virtue of molecular methods. Serology data suggest that infections with human polyomaviruses (HPyVs)

Risk Factors for the Development of BK Polyomavirus and Treatment Outcomes in Kidney Transplant Recipients: An 8‐Year Retrospective Cohort Study

Nephrology, Volume 30, Issue 6, June 2025.
ABSTRACT Background BKPyV‐DNAemia occurs in up to 30% of kidney transplant recipients (KTRs), with graft‐threatening BKPyV‐nephropathy in up to 10%. Risk factors for BKPyV‐DNAemia, BKPyV‐nephropathy, and associated graft loss are incompletely described.

BK polyomavirus infection: more than 50 years and still a threat to kidney transplant recipients

Frontiers in Transplantation
BK polyomavirus (BKPyV) is a ubiquitous human polyomavirus and a major infection after kidney transplantation, primarily due to immunosuppression. BKPyV reactivation can manifest as viruria in 30%–40%, viremia in 10%–20%, and BK polyomavirus-associated ...

A Review on JC Virus Infection in Kidney Transplant Recipients

Clinical and Developmental Immunology, 2013
The polyomavirus (PyV), JC virus (JCV), is a small nonenveloped DNA virus that asymptomatically infects about 80% of healthy adults and establishes latency in the kidney tissue.

First Documented Case of BK Nephropathy in Kidney Transplant Recipient in Croatia: Usage of Urine Cytology in Evaluation Process [PDF]

, 2010
BK virus associated nephropathy (BKVAN) in transplanted kidney, although recognized as a distinct entity in the 1970-es, continues to represent a challenge in kidney transplantation, mainly because the optimal treatment approach has not been determined ...
