BK virus (BKV), a common infection, rarely causes illness except in immunocompromised individuals. Early diagnosis and managing immunosuppression are key for treating BKV-associated nephropathy in kidney transplant patients.

Area of Science:

  • Virology
  • Immunology
  • Nephrology

Background:

  • BK virus (BKV) infects up to 90% of the population, usually asymptomatic.
  • Clinical manifestations are rare, primarily affecting immunocompromised individuals.
  • BKV is linked to various conditions including hemorrhagic cystitis, ureteric stenosis, and nephropathy in transplant recipients.

Purpose of the Study:

  • To highlight the complexities of BKV-associated diseases, particularly polyomavirus-associated nephropathy (PAN).
  • To discuss challenges in BKV disease intervention and the importance of host, organ, and viral factors.
  • To review diagnostic strategies and therapeutic options for PAN.

Main Methods:

  • Review of existing literature on BKV infections and associated pathologies.

  • Analysis of diagnostic approaches including urine cytology and plasma BKV load.
  • Evaluation of therapeutic interventions, including immunosuppression modulation and antiviral agents.

    • Main Results:

    • Polyomavirus-associated nephropathy (PAN) poses a significant threat to renal transplantation success.
    • Early diagnosis of PAN is achievable through urine cytology and plasma BKV load monitoring.
    • Reduced immunosuppression and potential use of cidofovir show promise in managing PAN.

    Conclusions:

    • BKV diseases, especially PAN, require a multifactorial approach involving host, organ, and viral determinants.
    • Improved diagnostic tools enable earlier detection and intervention for PAN.
    • Management strategies focus on immune control, with potential roles for antivirals like cidofovir.
