Abstract

The hemolytic uremic syndrome is a clinical syndrome defined by the presence of thrombocytopenia, microangiopathic hemolytic anemia and acute renal failure. Atypical hemolytic uremic syndrome (aHUS) which is not usually associated with prodromal symptoms, especially diarrhea, has a higher mortality rate and a stronger tendency to progress to chronic renal failure. In approximately 30-50% of patients with aHUS, mutations have been detected in complement factor H, membrane cofactor protein or factor I. Mutations in the complement regulator factor H are the most frequent and have a very poor prognosis, with most patients developing ESRD. We have experienced a 33-year-old man with a family history of renal failure diagnosed as aHUS resulted from factor H mutation, for whom we carried out hemodialysis, plasmapheresis and other conservative management.
