Varying degrees of renal dysfunction, thrombocytopenia, and hemolysis may be seen in each syndrome. When renal failure in addition to microangiopathic hemolysis and thrombocytopenia is present, HUS is diagnosed.2 The nomenclature, however, is confused by the presence of overlapping clinical features.
