15 years old patient presented with clinical syndrome of fever, fatigue, and diarrhea. Laboratory findings showed severe anemia with findings of microangiopathic hemolysis (schistocytes, hyperbilirubinemia, elevated LDH) and severe thrombocytopenia.

He also had urinary findings of hematuria, moderate proteinuria, and creatinine as high as 1.4 mg/dL.
