Learn About Hemolytic-Uremic Syndrome

What is the definition of Hemolytic-Uremic Syndrome?

Shiga-like toxin producing E coli hemolytic-uremic syndrome (STEC-HUS) is a disorder that most often occurs when an infection in the digestive system produces toxic substances. These substances destroy red blood cells and cause kidney injury.

What are the alternative names for Hemolytic-Uremic Syndrome?

HUS; STEC-HUS; Hemolytic-uremic syndrome

What are the causes of Hemolytic-Uremic Syndrome?

Hemolytic-uremic syndrome (HUS) often occurs after a gastrointestinal infection with E coli bacteria (Escherichia coli O157:H7). However, the condition has also been linked to other gastrointestinal infections, including shigella and salmonella. It has also been linked to nongastrointestinal infections.

HUS is most common in children. It is the most common cause of acute kidney failure in children. Several large outbreaks have been linked to undercooked hamburger meat contaminated with E coli.

E coli can be transmitted through:

  • Contact from one person to another
  • Consuming uncooked food, such as milk products or beef

STEC-HUS is not to be confused with atypical HUS (aHUS) which is not infection-related. It is similar to another disease called thrombotic thrombocytopenic purpura (TTP).

What are the symptoms of Hemolytic-Uremic Syndrome?

STEC-HUS often begins with vomiting and diarrhea, which may be bloody. Within a week, the person may become weak and irritable. People with this condition may urinate less than normal. Urine output may almost stop.

Red blood cell destruction leads to symptoms of anemia.

Early symptoms:

  • Blood in the stools
  • Irritability
  • Fever
  • Lethargy
  • Vomiting and diarrhea
  • Weakness

Later symptoms:

  • Bruising
  • Decreased consciousness
  • Low urine output
  • No urine output
  • Pallor
  • Seizures -- rare
  • Skin rash that looks like fine red spots (petechiae)

What is the outlook (prognosis) for Hemolytic-Uremic Syndrome?

This is a serious illness in both children and adults, and it can cause death. With proper treatment, more than half of people will recover. The outcome is better in children than adults.

What are the possible complications of Hemolytic-Uremic Syndrome?

Complications may include:

  • Blood clotting problems
  • Hemolytic anemia
  • Kidney failure
  • Hypertension leading to seizures, irritability, and other nervous system problems
  • Too few platelets (thrombocytopenia)
  • Uremia

  • No urination
