Atypical hemolytic-uremic syndrome: clinical presentation, diagnosis and treatment

Résumé fourni par la source

Atypical hemolytic-uremic syndrome (aHUS) is a rare disease caused by uncontrolled activation of the alternative complement pathway and characterized by acute kidney injury, thrombocytopenia, and microangiopathic hemolytic anemia. Up to one third of aHUS patients present with extrarenal manifestations including central nervous system, lung, liver, and gastrointestinal tract involvement. Identified triggers of aHUS include various complement activating disorfers, e.g. complicated pregnancy. Eculizumab, the terminal complement C5 inhibitor, is targeted treatment approved for patients with aHUS. The authors present two cases of aHUS and review its clinical presentation, diagnosis and treatment.
