Torque teno virus as a marker of immune status in immunocompromised patients: A systematic review

European Journal of Clinical Investigation, Volume 55, Issue 8, August 2025.
Abstract Background Torque teno virus (TTV) is not known to cause disease in humans; however, chronic inflammatory conditions and immunosuppression states can favour TTV replication. This study aimed to verify the effectiveness of TTV as an immune biomarker.

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.

Performance of an automated platform for CMV, EBV and BKPyV DNA detection and quantification

Journal of Clinical Virology Plus
Quantification of cytomegalovirus (CMV), Epstein-Barr virus (EBV), and BK polyomavirus (BKPyV) DNA is crucial for diagnosing related infections. The analytical performance of the Altostar® CMV, EBV and BKPyV DNA assays used in the AltoStar® AM16 instrument was assessed.The Limit of detection was 215 international units/ml (IU/ml) for the CMV assay, 330

Reactivation of BK Polyomavirus in Urine Cytology Is Not Associated with Urothelial Cell Carcinoma

Viruses, 2020
BK polyomavirus (BKPyV) has been associated with some high-grade and special urothelial cell carcinoma (UCC) subtypes in immunosuppressed patients. Here, we evaluated the relationship of BKPyV-positive urine cytology specimens (UCS) with UCC.

Identification of Rab18 as an Essential Host Factor for BKPyV Infection Using a Whole Genome RNA Interference Screen

, 2017
BK polyomavirus (BKPyV) is a human pathogen first isolated in 1971. BKPyV infection is ubiquitous in the human population, with over 80% of adults worldwide being seropositive for BKPyV.

Pre-transplant immune factors may be associated with BK polyomavirus reactivation in kidney transplant recipients.

PLoS ONE, 2017
BK polyomavirus (BKPyV) reactivation in kidney transplant recipients can lead to allograft damage and loss. The elements of the adaptive immune system that are permissive of reactivation and responsible for viral control remain incompletely described. We

Characterization of BKPyV-specific monoclonal antibodies in kidney transplant recipients after BKPyV reactivation

Caractérisation des anticorps monoclonaux spécifiques au BKPyV chez les greffés de rein après la réactivation du BKPyV Le polyomavirus BK (BKPyV) est ubiquitaire et persiste asymptomatiquement dans le rein. La réactivation virale peut être observée chez les greffés du rein qui reçoivent des traitements d'immunosuppression.
