Primary immunodeficiency
What is Primary Immunodeficiency?
People with primary immunodeficiency have an immune system that does not work correctly. This means that people with primary immunodeficiency are more likely to get and become very sick from infections2.
Symptoms
People with primary immunodeficiency are more likely to have symptoms such as2
- More frequent or repeated infections
- Infections that last longer than in most people
- Infections that are hard to treat and do not respond to antibiotics or require IV antibiotics
- Infections that are more severe and require hospitalization, such as sepsis or abscesses (pus-filled infections) of internal organs
- Infections that most people don’t get (sometimes called opportunistic infections)
- Lack of weight gain or growth in an infant (failure to thrive)
- Digestive problems, such as chronic diarrhea
Please always consult healthcare professionals about these symptoms and for further advice on primary immunodeficiency.
Causes
The cause is frequently found to be genetic. Some immunodeficiencies are caused by a single faulty gene and others by a combination of genes. The fault may be inherited, be a new mutation in one of your genes or it may have been inherited from one or both of your parents. Most commonly, a faulty gene does not matter, unless the same fault is inherited from both parents. 1
Treatment for primary immunodeficiency
Immunoglobulin replacement therapy is one of the medical therapies available to treat immunodeficiency.
Immunoglobulin replacement therapy can be given through an IV, or under the skin, (subcutaneous, SCIg). Both methods are effective at replacing immunoglobulin (IgG) to levels necessary to fight infection3. Always consult healthcare professionals for advice on immunodeficiency.
