Conditions

BK Polyomavirus DNAemia after kidney transplantation

Brief summary

Time from randomization to end of BKPyV-DNAemia, where end of BKPyV-DNAemia is defined as the first time point after randomization with BKPyV DNA <1,000 IU/ml or a decline in BKPyV DNA of >1 log10 IU/ml (>90% curtailing) as the best-established surrogate marker in the literature for clearance of BKPyV infection.

Detailed description

Change from baseline to month 9 in estimated glomerular filtration rate (eGFR), Occurrence of acute rejection episodes, Occurrence of donor-specific antibodies, Occurrence of graft loss, Number and dose of immunosuppressants, Trough levels of immunosuppressants, Overall and CNI immunosuppressive scale (IS) units, Level of BKPyV-specific CD4 T cells, Occurrence of BKPyV re-infections
