This contrasts with HUS causally linked to the deficiency of proteins that regulate the alternative pathway of complement, either due to genetic mutations or the presence of autoantibodies (mainly to complement factor H), or to other genetic and metabolic causes (Box 26.1). In children, more than 80 % of cases of HUS are due to STEC infection.

Stx and NA are thought to injure vascular endothelial and perhaps circulating red blood cells and platelets leading to thrombotic microangiopathy with intravascular hemolysis (TMA).

Major triggers of postinfectious HUS are Shiga toxin (Stx) producing bacteria (STPB, mainly Escherichia coli and Shigella dysenteriae type 1) and neuraminidase (NA) producing organisms (mainly Streptococcus pneumoniae). pneumoniae, influenza A and HIV and discusses potential interactions between these pathogens and the complement system.įor the purpose of this section, we define postinfectious hemolytic uremic syndrome as HUS caused by specific infectious organisms in patients with no identifiable HUS-associated genetic mutation or autoantibody. The remainder of this chapter highlights rarer forms of (post-infectious) HUS due to S. The outcome of STEC-HUS is generally favorable, but chronic kidney disease, permanent extrarenal, mainly cerebral complication and death (in less than 5 %) occur and long-term follow-up is recommended. Treatment of STEC-HUS is supportive more investigations are needed to evaluate the efficacy of putative preventive and therapeutic measures, such as non-phage-inducing antibiotics, volume expansion and anti-complement agents. Clinicians should always strive for an etiological diagnosis through the microbiological or molecular identification of Stx-producing bacteria and Stx or, if negative, serological assays. STEC disease is characterized by hematological (microangiopathic hemolytic anemia), renal (acute kidney injury) and extrarenal organ involvement. This chapter reviews the epidemiology and pathogenesis of STEC-HUS, including bacterial-derived factors and host responses. The majority of episodes is due to infections by Shiga toxin (Stx) producing Escherichia coli (STEC). Post-infectious hemolytic uremic syndrome (HUS) is caused by specific pathogens in patients with no identifiable HUS-associated genetic mutation or autoantibody.
