ABSTRACT
Atypical Hemolytic Uremic Syndrome (aHUS) is a rare, life-threatening disease that can occur at any age and be sporadic or familial. aHUS is caused by an uncontrolled activation of the complement system. Plasma Exchange (PE) has been the standard treatment for years with poor results, leading approximately 40% of patients to end-stage renal disease (ESRD) or death during the first clinical manifestation. Eculizumab, an humanized monoclonal antibody directed against complement component C5, has emerged in the last few years as a new therapheutic aproach with promising results. Our goal is to present a case of an adult patient where eculizumab was sucessfully used as upfront therapy avoiding the potential significant morbidity of PE.
