AI Article Synopsis

  • Transplantation is the preferred treatment for most patients with kidney failure, and the complement system is crucial to this process.
  • Dysregulation of the complement system leads to various kidney-related diseases and impacts post-transplant issues such as rejection and graft function.
  • Understanding the complement cascade can guide strategies for preventing complications during kidney transplantation, with new therapeutic options being developed to enhance graft survival.

Article Abstract

Transplantation is the treatment of choice in most patients with kidney failure. The complement system plays a vital role in transplantation. The complement system forms a major part of innate immunity and acts as a bridge between innate and acquired immunity. Many diseases, particularly concerning the kidneys, result from complement system dysregulation, like atypical hemolytic uremic syndrome (aHUS), C3 glomerulopathy (C3GN), systemic lupus erythematosus (SLE and some other immune complex diseases. The complement system activation is a very important part of post-transplant events like ischemia-reperfusion injury (IRI), delayed graft function (DGF), antibody-mediated rejection (ABMR) and thrombotic microangiopathy (TMA). A better understanding of the complement cascade can help to plan strategies to prevent and manage complement-related problems before and after kidney transplantation. Many newer molecules are either being developed or in the pipeline, which target the complement system at various stages. These novel therapeutics are now considered additional measures to improve graft survival. This review summarises the complement cascade, its role in kidney diseases and kidney transplantation, and possible areas of target and novel therapeutics.
