How many types of hemolytic anemia are there?

The three main types of immune hemolytic anemia are autoimmune, alloimmune, and drug-induced.

What are the types of haemolytic Anaemia?

Types of acquired hemolytic anemia include:

  • immune hemolytic anemia.
  • autoimmunehemolytic anemia (AIHA)
  • alloimmune hemolytic anemia.
  • drug-induced hemolytic anemia.
  • mechanical hemolytic anemias.
  • paroxysmal nocturnal hemoglobinuria (PNH)
  • malaria, babesiosis and other infectious anemias.

What is intrinsic and extrinsic hemolytic anemia?

Etiology of Hemolytic Anemia

Extrinsic: From a source outside the red cell; disorders extrinsic to the RBC are usually acquired. Intrinsic: Due to an defect within the red cell; intrinsic RBC abnormalities (see table Hemolytic Anemias) are usually inherited.

What is the most common cause of hemolytic anemia?

They are caused by immune problems, medicines and other factors. The most common extrinsic form is autoimmune hemolytic anemia. This is when your body’s immune system becomes confused and makes antibodies that attack your own blood cells. When your body attacks its own cells it is called “autoimmune”.

What is the difference between intravascular and extravascular hemolysis?

Intravascular hemolysis occurs when erythrocytes are destroyed in the blood vessel itself, whereas extravascular hemolysis occurs in the hepatic and splenic macrophages within the reticuloendothelial system.

What are the signs of hemolytic anemia?

What are the symptoms of hemolytic anemia?

  • Abnormal paleness or lack of color of the skin.
  • Yellowish skin, eyes, and mouth (jaundice)
  • Dark-colored urine.
  • Fever.
  • Weakness.
  • Dizziness.
  • Confusion.
  • Can’t handle physical activity.

How long can you live with hemolytic anemia?

These blood cells normally live for about 120 days. If you have autoimmune hemolytic anemia, your body’s immune system attacks and destroys red blood cells faster than your bone marrow can make new ones. Sometimes these red blood cells live for only a few days. Most people who get AIHA are middle-aged or older.

What is the treatment for hemolytic anemia?

Treatments for hemolytic anemia include blood transfusions, medicines, plasmapheresis (PLAZ-meh-feh-RE-sis), surgery, blood and marrow stem cell transplants, and lifestyle changes. People who have mild hemolytic anemia may not need treatment, as long as the condition doesn’t worsen.

Who is at risk for hemolytic anemia?

Hemolytic anemia can affect people of all ages and races and both sexes. Some types of hemolytic anemia are more likely to occur in certain populations than others. For example, glucose-6-phosphate dehydrogenase (G6PD) deficiency mostly affects males of African or Mediterranean descent.

What infections cause hemolytic anemia?

Some infections that are incriminated in hemolytic anemia and that can be transmission via blood transfusions include: hepatitis, CMV, EBV, HTLV-1, malaria, Rickettsia, Treponema, Brucella, Trypanosoma, Babesia, etc.

Does anemia lower your immune system?

Research has shown iron deficiency anaemia can affect your immune system – the body’s natural defence system. This increases your vulnerability to infection.

How common is hemolytic anemia?

In the case of WAHA and other types of autoimmune hemolytic anemia, red blood cells are “tagged” by antibodies and are then destroyed by other types of immune cells. WAHA is the most common type of autoimmune hemolytic anemia; it affects approximately 1 to 3 per 100,000 people every year and can occur at any age.

What drugs can cause hemolytic anemia?

Drugs that can cause this type of hemolytic anemia include:

  • Cephalosporins (a class of antibiotics), most common cause.
  • Dapsone.
  • Levodopa.
  • Levofloxacin.
  • Methyldopa.
  • Nitrofurantoin.
  • Nonsteroidal anti-inflammatory drugs (NSAIDs)
  • Penicillin and its derivatives.


What is the process of hemolysis?

Hemolysis, also spelled haemolysis, also called hematolysis, breakdown or destruction of red blood cells so that the contained oxygen-carrying pigment hemoglobin is freed into the surrounding medium.

How is hemolysis diagnosed?

Diagnosis of Hemolytic Anemia

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.

What happens during extravascular hemolysis?

Extravascular hemolysis

In this case little hemoglobin escapes into blood plasma. The macrophages of the reticuloendothelial system in these organs engulf and destroy structurally-defective red blood cells, or those with antibodies attached, and release unconjugated bilirubin into the blood plasma circulation.
