Haufen Diagnostic Biomarkers of BK Renal Disease

To prospectively test whether the detection of three-dimensional, cast-like polyomavirus aggregates, termed Haufen, in voided urine samples can serve as an accurate biomarker of intra-renal disease, i.e. polyoma-BK-virus nephropathy (PVN). We want to correlate the detection of 'Haufen' with histologic findings made in renal biopsies as well as signs of polyomavirus activation, i.e. viremia and viruria. The prospective study is designed to further validate our retrospective findings (manuscript in press, J Am Soc Nephrology) and more specifically to correlate 'Haufen' shedding with the histologically confirmed course of PVN.

Treatment and study plan

Renal Allograft Biopsy

Procedure

A renal allograft biopsy will be performed when the urine is determined to be Haufen negative.

Primary outcomes

  1. Correlate Haufen, urine and plasma data with the clinical presentation and - in selected cases - with renal biopsy findings.

    Time frame: The biopsy will be performed when urine is determined to be Haufen negative
