NCT02758288

Brief Summary

The investigator's aim in this study is to evaluate the impact of a new standard of care protocol for the treatment of BK viremia and nephropathy (BKVAN), which includes switching from Tacrolimus to equivalent dose of Cyclosporine in patients who have been diagnosed with BK viremia or BKVAN based on their viral load, overall graft function (estimated glomerular filtration rate), acute rejection, and rate of graft loss due to rejection or BKVAN.

Outcome Measures

Primary Outcomes (1)

  • Kidney function to compare effectiveness of a new care protocol for the treatment of BK viremia (BK PCR viral load over 500 copy) and BKVAN (confirmed by kidney biopsy) with a similar cohort treated with traditional methods.

    12 months

Secondary Outcomes (4)

  • Rate of BK nephropathy in both treatment groups confirmed by kidney biopsy

    24 months

  • Rate of acute cellular or humoral rejection in both treatment groups confirmed by kidney biopsy

    24 months

  • Rate of graft loss in both group as determined by elevated creatinine level and kidney biopsy

    24 months

  • Estimated glomerular filtration rate (eGFR) at start of the study (0) , 3, 6, 12 and 24 months between two groups

    3, 6, 12, 24 months

Study Arms (2)

New Protocol to treat BK viremia or BKVAN

Adult kidney recipients who are determined to have BK viremia with a BK PCR viral load over 500 copy post-transplant treated with a new treatment protocol, prospective data collection approach

Other: New Protocol - BK viremia or BK virus nephropathy

Standard Protocol to treat BK viremia or BKVAN

Adult kidney recipients who are determined to have BK viremia with a BK PCR viral load over 500 copy post-transplant treated with a traditional standard of care protocol, retrospective data collection approach

Other: Standard Protocol - BK viremia or BK virus nephropathy

Interventions

Data collected prospectively that will follow new clinical practice guidelines that were developed by Loma Linda Nephrology group with collaboration with Transplant surgeons to improve care of patients complicated with BK viremia or BK virus nephropathy.
