Complement-Mediated Kidney Diseases Toolkit

Complement-Mediated Kidney DiseaseS Toolkit

Complement-mediated kidney diseases (CMKDs), although less well-known and considered rare, are an important and complex area of kidney health that needs to be better recognized so that optimal care may be provided.

There are over 40 activating and inhibiting proteins in three separate pathways of complement system that finally converge into a common terminal pathway. The kidney is particularly susceptible to damage by complement. Activation of the complement system is tightly regulated by a series of soluble and membrane bound proteins. Failure of these checking mechanisms is one of the major causes and/or drivers of CMKDs.

Raising awareness of these diseases and developing educational and implementation tools supports clinicians in building their understanding of CMKDs, and in their clinical practice.

Discover the toolkit below, and stay tuned as more tools and resources are added periodically.

ISN Global Kidney Care Podcast on CMKDs

A Beginner's Guide to Kidney HealthIn this podcast, Drs Namrata Parikh, Gary Chan and Nick Medjeral-Thomas discuss key clinical and pathology features of inappropriate, pathogenic complement activity that guide physicians to a diagnosis of C3 glomerulopathy. They discuss differences in investigation and management strategies between their respective clinical centers in Ottawa, Hong Kong and London, including access to clinical trials of therapeutic complement inhibitors. To finish, they speculated on the future impact on clinical nephrology of complement pathway analysis and inhibition.

ISN October 2022 eDigest on CMKDs

ISN’s October ’22 eDigest presents recent publications in Kidney International Reports on the pathophysiology, progression, treatment, and validation of complement-mediated kidney diseases. It also highlights four original papers, in the field of complement-mediated kidney diseases, that have been published in Kidney International within the past few months. Explore the eDigest here.

Nicholas Medjeral-Thomas

Nicholas Medjeral-Thomas is a kidney physician and clinician scientist at Imperial College London. His research focuses on the role of complement deregulation in C3 glomerulopathy and IgA nephropathy pathogenesis. He has made a number of important discoveries that improve our understanding of both these conditions. Most recently, he has investigated associations with and the potential pathogenic role of a protein called factor H related protein 5 (FHR5) in IgA nephropathy and C3 glomerulopathy. He has also investigated associations between lectin complement pathway proteins and COVID-19.
