    Abstract:
    Shiga toxin-producing Escherichia coli hemolytic uremic syndrome (STEC-HUS) is the most common cause of acute renal failure in children, and it is associated with thrombocytopenia and hemolytic anemia. Although this disease primarily affects the kidney, it can also contribute to cellular damage in other organ systems, such as the CNS. Eculizumab is a monoclonal antibody that binds to complement proteins to prevent complement-mediated intravascular hemolysis in atypical HUS. In STEC-HUS, complement activation also occurs by Shiga toxin, and previous cases of eculizumab use in the setting of neurological involvement have been shown to be successful. We report the successful use of eculizumab in the setting of typical STEC-HUS-induced neurological symptoms including seizure, altered mental status, and left arm weakness. The patient also experienced concomitant renal failure requiring dose adjustment for hemodialysis. Following 2 doses of eculizumab, our patient was discharged to an inpatient rehabilitation facility with resolution of her renal injury, seizures, and altered mentation without adverse effects from eculizumab throughout the admission. Based on our case study, it appears that eculizumab may be given during or between hemodialysis without dose adjustment.
