[Atypical hemolytic and uremic syndrome in Algeria: diagnostic difficulties and therapeutic constraints].

Atypical Hemolytic Uremic Syndrome (aHUS) is a systemic disease due to dysregulation of the alternate complement pathway, mortality is estimated at 10% and more than 50% of patients progress to end-stage renal disease. The aim of this study was to summarize the clinical data and biological results as well as the evolution and management of patients with aHUS seen over a period of four years in one specialized department in Algeria. Our study was observational and longitudinal.
