Adult hemolytic-uremic syndrome associated with urosepsis due to Shigatoxin-producing Escherichia coli O138:H-.

We report the case of a 62-year-old man without prodromal symptoms who developed a hemolytic-uremic syndrome (HUS) one week after the diagnosis of an acute bacteremic urinary infection (UTI). In this patient, the E. coli isolated in blood cultures was a non-O157:H7 Shigatoxin-producing strain that could subsequently be identified as O138:H-.
