Primary immunodeficiency syndromes Mostly these are inherited single-gene disorders that present in infancy or early childhood with the exception of common variable immunodeficiency which usually occurs in adults. Knowledge about the function and diversity of B cells in health and disease has now become quite detailed but there is still much to learn. The International Union of Immunological Societies Expert Committee for Primary Immunodeficiency has identified main categories as follows: Combined immunodeficiencies.

Combined immunodeficiencies with associated or syndromic features. Predominantly antibody deficiencies. Complement deficiencies. Congenital defects of phagocyte number, function, or both.

Paediatric patients. Adult and paediatric patients. Each disorder has unique symptoms that can be frequent or chronic. Some of these symptoms can include:. If your doctor thinks you might have an immunodeficiency disorder, they will want to do the following:. Vaccines can test your immune system response in what is called an antibody test. Your doctor will give you a vaccine. Then they will test your blood for its response to the vaccine a few days or weeks later.

The treatment for each immunodeficiency disorder will depend on the specific conditions. For example, AIDS causes several different infections. Your doctor will prescribe medications for each infection. And you may be given an antiretroviral to treat and HIV infection if appropriate. Treatment for immunodeficiency disorders commonly includes antibiotics and immunoglobulin therapy.

Other antiviral drugs, amantadine and acyclovir, or a drug called interferon are used for treatment of the viral infections caused by immunodeficiency disorders. Secondary disorders can be prevented in a number of ways. Sleep is very important for a healthy immune system.

According to the Mayo Clinic , adults need about eight hours of sleep per night. Most doctors agree that people with immunodeficiency disorders can lead full and productive lives. Early identification and treatment of the disorder is very important. White blood cells, or WBCs, are an important part of your immune system.
