What is atypical HUS diagnosis?

Atypical hemolytic uremic syndrome (aHUS) is a rare syndrome of hemolysis, thrombocytopenia, and renal insufficiency. Genetic mutations in the alternate pathway of complement are well recognized as the cause in more than 60% of patients affected by this thrombotic microangiopathy.

What is typical and atypical HUS?

The classic form (typical HUS) is associated with a Shiga-like toxin often related to E. coli serotype O157:H7. The atypical HUS (aHUS) form is due to an overactivation of the alternative pathway of complement and carries a reserved prognosis with high mortality and morbidity in the acute phase.

How do you test for aHUS?

To see if you have aHUS, doctors will do tests, including:

  1. A blood count (CBC) test, which will measure your red blood cell and platelet counts. Having low amounts of red blood cells and platelets in your body can be a sign of aHUS.
  2. Blood tests to see how well your kidneys are working, such as an eGFR test.

Is Atypical HUS an autoimmune disease?

Atypical hemolytic uremic syndrome (aHUS) can co-exist with autoimmune disorders, complicating the diagnosis of the rare blood-clotting disease, a case report shows. The findings highlight the need for genetic testing to diagnose aHUS in complex cases, the researchers said.

What causes atypical HUS?

Causes. Atypical hemolytic-uremic syndrome often results from a combination of environmental and genetic factors. Mutations in at least seven genes appear to increase the risk of developing the disorder.

How long do you live with aHUS?

During the era when plasma infusion or plasma exchange was the mainstay of management, aHUS was associated with a poor prognosis. Historically, 36% of children and 64% of adults developed end-stage renal disease or died within 3 to 5 years of disease onset [3].

Can you live with aHUS?

Atypical hemolytic uremic syndrome (aHUS) is a disease that causes blood clots in small blood vessels in your kidneys and other organs. These clots keep blood from getting to your kidneys, which can lead to serious medical problems, including kidney failure. There’s no cure, but treatment can help manage the condition.

What is the difference between HUS and aHUS?

Typical HUS (ie, STEC-HUS) follows a gastrointestinal infection with STEC, whereas aHUS is associated primarily with mutations or autoantibodies leading to dysregulated complement activation.

How do you get Atypical HUS?

Is Atypical HUS curable?

There’s no cure, but treatment can help manage the condition. Besides kidney failure, complications from aHUS can include: Hemolytic anemia (red blood cells dying faster than you can make them)

Is aHUS a terminal illness?

Atypical hemolytic uremic syndrome (aHUS) is an extremely rare, life-threatening, progressive disease that frequently has a genetic component. In most cases it can be effectively controlled by interruption of the complement cascade.
