Case Report of Atypical Hemolytic Uremic Syndrome in a Young Norwegian Male

Abstract

Atypical hemolytic uremic syndrome (aHUS) is a rare, life-threatening thrombotic microangiopathy characterized by complement dysregulation. This report presents a 19-year-old male from Oslo, Norway, who developed severe anemia, thrombocytopenia, and acute kidney injury following a viral infection. Complement factor mutations were identified, confirming aHUS. Eculizumab therapy led to rapid hematologic and renal recovery. This case highlights the importance of early diagnosis and targeted treatment in aHUS.
