Board Review Bonus #2: Minimal Change Disease

In this special bonus episode of the podcast, Koyal and Kenar provide a maximally useful review of minimal change disease, from diagnosis (including secondary causes to screen for) to treatment options, including how to decide which patients may do better with which therapies. 

Can’t get enough minimal change? Check out Episode 6 (with Astrid Weins) and Episode 7 (with Felicitas Hengel and Nicola Tomas) for more on the potential role of anti-nephrin autoantibodies in MCD.
