Characteristics and management of thrombotic microangiopathy in kidney transplantation

Thrombotic microangiopathy is not a rare complication of kidney transplantation and is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury with extensive thrombosis of the arterioles and capillaries. Various factors can cause thrombotic microangiopathy after...

description Thrombotic microangiopathy is not a rare complication of kidney transplantation and is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury with extensive thrombosis of the arterioles and capillaries. Various factors can cause thrombotic microangiopathy after kidney transplantation, including surgery, warm and cold ischemia-reperfusion injury, exposure to immunosuppressants, infection, and rejection. Many recent studies on atypical hemolytic uremic syndrome have described genetic abnormalities related to excessive activation of the alternative complement pathway. The affected patients’ genetic backgrounds revealed significant genetic heterogeneity in several genes involved in complement regulation, including the complement factor H, complement factor H-related proteins, complement factor I, complement factor B, complement component 3, and CD46 genes in the alternative complement pathway. Although clinical studies have provided a better understanding of the pathogenesis of diseases, the diverse triggers present in the transplant environment can lead to thrombotic microangiopathy, along with various genetic predispositions, and it is difficult to identify the genetic background in various clinical conditions. Given the poor prognosis of posttransplant thrombotic microangiopathy, further research is necessary to improve the diagnosis and treatment protocols based on risk factors or genetic predisposition, and to develop new therapeutic agents.
