What is the difference between HUS and TTP?

What is the difference between HUS and TTP?

HUS is related to thrombotic thrombocytopenic purpura (TTP), but it occurs more often in children and more often causes kidney failure, whereas TTP is more common among adults. The small blood clots that form in HUS block small blood vessels throughout the body, particularly those in the brain, heart, and kidneys.

What are the symptoms of hemolytic uremic syndrome?

The initial signs and symptoms of this form of HUS may include: Diarrhea, which is often bloody. Abdominal pain, cramping or bloating. Vomiting….When to see a doctor

  • Decreased urine output.
  • Swelling.
  • Unexplained bruises.
  • Unusual bleeding.
  • Extreme fatigue.

Is hemolysis good or bad?

The result is an extremely fast destruction of red blood cells, which can be lethal. This is why healthcare providers need to carefully check blood types before giving blood. Some causes of hemolytic anemia are temporary. Hemolytic anemia may be curable if a doctor can identify the underlying cause and treat it.

What lab tests differentiate between immune and nonimmune hemolytic anemias?

A direct Coombs test (also known as a direct antiglobulin test, or DAT) is useful to distinguish between immune and nonimmune hemolysis….

What are the laboratory findings in HUS?

HUS is primarily a clinical diagnosis disorder with characteristic laboratory findings. The hemoglobin level is typically less than 8g/dL with a negative Coomb’s test and elevated reticulocyte count. Thrombocytopenia is often mild to moderate (average of 60 x 103/microL).

How does hemolytic anemias affect the liver function?

In hemolytic anemia, jaundice and hepatosplenomegaly are often seen mimicking liver diseases. In hematologic malignancies, malignant cells often infiltrate the liver and may demonstrate abnormal liver function test results accompanied by hepatosplenomegaly or formation of multiple nodules in the liver and/or spleen.

What lab test confirms hemolytic anemia?

Diagnosis. Hemolysis is suspected in patients with anemia and reticulocytosis. If hemolysis is suspected, a peripheral smear is examined and serum bilirubin, LDH, haptoglobin, and ALT are measured. The peripheral smear and reticulocyte count are the most important tests to diagnose hemolysis.
