Atypical hemolytic uremic syndrome

Atypical hemolytic uremic syndrome is a rare, life-threatening form of thrombotic microangiopathy characterized by uncontrolled activation of the alternative complement pathway This dysregulation causes widespread endothelial damage and systemic microvascular thrombosis, predominantly injuring the renal microvasculature while potentially involving the cardiovascular, central nervous, and gastrointestinal systems Clinically, it presents across pediatric and adult populations with the classic tria...

Unlike typical hemolytic uremic syndrome, atypical hemolytic uremic syndrome is not caused by Shiga toxin-producing infections and frequently stems from genetic mutations or autoantibodies affecting complement regulatory proteins, carrying a significant risk of progression to end-stage renal disease
