Background and Objective
Hemolytic uremic syndrome (HUS) is characterized by triad of microangiopathic
hemolytic anemia, thrombocytopenia, and acute renal failure. It is more common in
children younger than the age of 4 years and is the most common cause of acute renal
failure in many parts of the world in this range of age. The classic form of the disease
occurs after an episode of acute diarrhea which may lead to chronic renal failure in 9% of
cases. Here in we report a case of HUS with recovery of renal function after 15 months
of dialysis.
Case report
A 12 year old boy was admitted with major clinical symptoms including acute bloody
diarrhea, followed by acute renal failure, thrombocytopenia and severe microangiopathic
hemolytic anemia. Peripheral blood smear showed probability of HUS. Peritoneal
dialysis was started and later followed by hemodialysis. Eventually after 15 months of
dialysis he obtained normal renal function and now after 3 years he is in good health with
normal renal function.
