Hemolytic uremic syndrome, abbreviated HUS, is the triad of:[1]

  • Microangiopathic hemolytic anemia.
  • Thrombocytopenia.
  • Acute renal failure.

Etiology

  • Verotoxins (from E. coli O157:H7) --> endothelial injury.[2]

Relation to thrombotic thrombocytopenic purpura (TTP)

  • TTP is the main (clinical) DDx of HUS.
    • It is classically characterized by: microangiopathic hemolytic anemia, thrombocytopenia, fever, mild renal failure, and prominent neurologic symptoms.
  • Both are classified as thrombotic microangiopathies.[3]

Etiology

  • Rare hamburger.
  • E. coli serotype O157:H7.
