Hemolytic Uremic Syndrome

  • Uma Ali

Hemolytic uremic syndrome (HUS) is a triad of thrombocytopenia, microangiopathic hemolysis, and acute kidney injury, within the broader category of thrombotic microangiopathy (TMA). The most common form of HUS in children is due to Shigatoxin-producing E. coli infection, although other forms due to invasive pneumococcal disease, genetic defects in complement regulation, and cobalamin C metabolism also occur. As the many forms of TMA share overlapping clinical features through the common pathomechanism of endothelial cell injury, laboratory investigation is warranted to provide additional diagnostic insight. Secondary forms of TMA also share clinical features with HUS, and although uncommon in children, should be excluded by careful assessment of the patient’s history and laboratory evaluation.
