In this episode of KDIGO Conversations in Nephrology, Dr. Carla Nester is joined by Dr. Anne-Marie van de Kar, Professor of Pediatrics at Radboud University Medical Center in the Netherlands, to discuss the role of complement in C3 glomerulopathy (C3G). They begin by defining C3G and exploring its pathophysiology, specifically focusing on the overactivation of the alternative pathway of the complement system.
Then, Drs. Nester and van de Kar delve into the specifics of why the alternative pathway is so central to C3G, including the role of autoantibodies like C3 nephritic factor (C3Nef) and genetic factors. Their discussion also covers the importance of diagnostic testing, including the role of kidney biopsies and biomarker analysis to identify the underlying cause and guide treatment, as well as the limitations of current C5 inhibition therapies and the promise of new treatments that target C3 activation directly.
