Brief summary
BK virus infection is one of the causes of renal allograft loss in the current era. Reduction of immunsuppression is the only intervention that prooved to be effective in treating of BK virus in kidney transplant recipient. However, there are evidences from retrospective and prospective studies showed that leflunomide and mTOR inhibitor such as everolimus or sirolimus have positive outcomes in treatment of BK virus in kidney tranplant recipient. The investigators conduct the RCT to compare the efficacy of leflunomide and mTOR inhibitor everolimus, in treatment of BK virus infected patients who do not respond to immunosuppression reduction.
Interventions
Everolimus will be given with tacrolimus.
Reduced dose tacrolimus will be given with leflunomide

Study design
Intervention model description
All patients met inclusion criteria will be randomized after BK VL not respond to mycophenolic acid and tacrolimus reduction as a run-in phase for 1 month. The intervention arms include everolimus + reduced dose tacrolimus and leflunomide + reduced dose tacrolimus.
Eligibility

Exclusion criteria
* BK VL \>10\^5 log * Previous BKVAN treatment * Drug hypersensitivity to mTORi or leflunomide
