Study Details

Brief summary:

Kidney transplantation (KT) is the best treatment modality available to date for patients with advanced kidney disease and the success of KT is dependent on maintaining a selective intricate balance between the risk of rejection and infections in KT recipients. BK virus is an important clinical infection affecting the post-transplant outcomes in KT recipients. BK nephropathy can affect 8-15% of patients after KT causing acute kidney injury, increased risk of rejection and fibrosis leading to additional hospital stays, increasing overall health care cost burden, and in some cases graft loss. The exact pathogenesis and treatment options for BK nephropathy are not clearly understood. It is debatable whether BK nephropathy is a full fledge donor-derived infection or reactivation of the recipient's latent infection. Irrespective of etiology, the common consensus is that treatment of BK virus infection depends on the selective restoration of host immune responses and balancing the risk of rejection vs worsening of infection.

Interventions and Outcome Measures

Arms

Main study

Single organ deceased donor kidney transplant recipients. Main study group subjects are enrolled at the time of transplant.

Sub-study

Single organ deceased donor Kidney Transplant Recipient who are newly diagnosed with BK Viremia or those with difficult-to-treat BKV > 3 logs (BKV log does not decrease by more than 1 log copy/ml drop on second per protocol lab). The sub-study group are enrolled once they are diagnosed with BK viremia post-transplant.

Interventions

Blood samples: Main Study group

the collection of blood samples at specified time points.

Data Collection

Donor and Recipient's clinical information including clinical history, demographic characteristics labs, and imaging.

Urine Sample- Main Study group

-Post-transplant monthly urine sample collection for 6 months in 10-18% of subjects

Urine sample- Sub-study group

\- Post-transplant monthly urine sample collection for 6 months in all subjects

Blood sample: Sub-study group

Monthly blood sample collection for 6 months

Primary outcome measure

  • Assessing the effect of kidney transplant immunosuppression therapy on the immune response against BK virus [ Time Frame: 24 months ]
