Twitter Poll (July 22, 2020)

Polyomavirus Nephropathy, Banff Class 3, Twitter Poll, Arkana Laboratories


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. Based on this score, the findings of the Banff working group showed that approximately 50% of these patients would develop graft failure at 24 months.
