Common variable immunodeficiency (CVID) is a disorder of the immune system characterized by low levels of specific immunoglobulins, antibodies produced by the immune system to fight infection or disease.
Immunodeficiency means that the immune system is deficient in one or more of its components and is unable to respond effectively to disease-producing organisms that invade the body.
Common variable immunodeficiency is believed to affect one in 50,000 to 200,000 individuals although it is not always diagnosed, and exact numbers of cases in the population cannot be accurately determined.

Immunodeficiency disorders are a group of disorders in which part of the immune system is missing or defective.
As a result, a child with an immunodeficiency disorder has frequent infections that are generally more severe and last longer than in a healthy child.
A person with an immunodeficiency disorder may get more frequent infections, heal more slowly, and have a higher incidence of some cancers.
Defects can occur in any component of the immune system or in more than one component (combined immunodeficiency).
Different immunodeficiency diseases involve different components of the immune system.
Congenital immunodeficiency is present at the time of birth and is the result of genetic defects.
These immunodeficiency disorders are also called primary immunodeficiencies.
Even though more than 70 different types of congenital immunodeficiency disorders have been identified, they rarely occur.
The congenital immunodeficiency disorder, Bruton's agammaglobulinemia, also known as X-linked agammaglobulinemia, results in a decrease or absence of B lymphocytes and, therefore, a decreased ability to make antibodies.
Common variable immunodeficiency (CVID) is another type of B lymphocyte deficiency.
Some types of immunodeficiency disorders affect both B lymphocytes and T lymphocytes.
For example, severe combined immunodeficiency disease (SCID) is caused by the defective development or function of these two types of lymphocytes.
Acquired immunodeficiency is more common than congenital immunodeficiency.
For example, the human immunodeficiency virus (HIV) is the virus that causes acquired immunodeficiency syndrome (AIDS).
HIV, however, is not the most common cause of acquired immunodeficiency.
Acquired immunodeficiency often occurs as a complication of other conditions and diseases.
For example, the most common causes of acquired immunodeficiency are malnutrition, some types of cancer, and infections.
In some cases, acquired immunodeficiency is brought on by drugs used to treat another condition.
The frequency of severe combined immunodeficiency is estimated to be one out of every 50,000 to 500,000 births, and of combined variable immunodeficiency, one out of every 10,000 to 50,000 births.
Congenital immunodeficiency is caused by genetic defects that generally occur while the fetus is developing in the uterus.
Acquired immunodeficiency is the result of a disease process, and it occurs later in life.
People with an immunodeficiency disorder tend to become infected by organisms that do not usually cause disease in healthy persons.
The major symptoms of most immunodeficiency disorders are repeated infections that heal slowly.
If a child is known to have an immunodeficiency disorder, a healthcare provider should be contacted if the child shows signs of having an infection, such as fever, vomiting, diarrhea, swelling of the lymph nodes, or unusual fatigue.
An immunodeficiency disorder is likely to be present when rare diseases occur or the patient gets ill from organisms that do not normally cause diseases, especially if the patient gets repeatedly infected.
When this happens in very young children, a genetic defect may be causing an immunodeficiency disorder.
When this situation occurs in older children or young adults, their medical history may indicate that childhood diseases may have caused an immunodeficiency disorder.
Laboratory tests are used to determine the exact nature of the immunodeficiency.
Blood contains antibodies, lymphocytes, phagocytes, and complement components, all of the major immune components that might cause immunodeficiency.
Lower than normal counts of either of these two cell types correlates with immunodeficiency.
The failure to respond to stimulants correlates with immunodeficiency.
There is no cure for congenital immunodeficiency disorders.
Common variable immunodeficiency also is treated with periodic infusions of IVIG throughout life.
In most cases, immunodeficiency caused by malnutrition is reversible.
The prognosis depends on the type of immunodeficiency disorder.
SCID is the most serious of the immunodeficiency disorders.
However, someone with a congenital immunodeficiency disorder might want to consider getting genetic counseling before having children in order to find out if there is a chance they will pass the defect on to their children.
Some of the infections associated with acquired immunodeficiency can be prevented or treated before they cause problems.
In general, people with immunodeficiency disorders should maintain a healthy diet because malnutrition can aggravate immunodeficiencies.
People with immunodeficiency disorders also should avoid eating undercooked food because it might contain bacteria that could cause infection.
While this food might not cause infection in others, it is a potential source of infectious organisms for someone with an immunodeficiency.
