Polyomavirus Nephropathy, Banff Class 3, Twitter Poll, Arkana Laboratories
ANSWER: C The answer is C, Polyomavirus Nephropathy, Banff Class 3. The Banff Working Group Classification was created by Nickeleit et al. to provide a classification scheme to aid communication, better standardize reporting of polyomavirus nephropathy, and provide a way for better comparative analysis of cases going forward. The classification is broken into three classes, Banff Class 1-3. This case highlights an example of a Polyomavirus Nephropathy, Banff Class 3 with a pvl score of 3 and ci (fibrosis) score of 2.

  ANSWER: True In 2018, Nickeleit et al. postulated a morphologic classification of polyomavirus nephropathy (PVN) based on pathologic features that correlate with clinical outcomes. The study defines 3 morphologic PVN classes using interstitial fibrosis and intra-renal PV load levels as statistically verified class denominators. It describes class 1 as an early PVN stage with favorable outcome, and classes 2 and 3 as having more pronounced impact on function with graft failure rates reaching 50% in class 3. The proposed PVN classification aims at improving clinico-pathologic correlation and the comparability of studies: a simple biopsy diagnosis of "PVN" no longer...
