Therapy for children with Shiga toxin-E. coli-associated hemolytic uremic syndrome

Hemolytic uremic syndrome(HUS) is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and acute nephropathy. Clinical features and outcome of children with HUS initiated by infections with Shiga toxin(Stx)-producing strains of Escherichia coli(E. coli) infection are different from those of patients with the other forms of HUS or thrombotic thrombocytopenic purpura(TTP). Childhood Stx-E. coli-associated HUS usually recovers spontaneously and dose not require specific treatments including plasma therapy. In contrast, a general consensus has been achieved that plasma exchange or infusion should always be tried in adult HUS/TTP to minimize the risk of death or long-term sequelae. In this paper, we briefly reviewed therapy for patients with Stx-E. coli-associated HUS.
