Cell-mediated immune deficiency, including T-cell immune deficiencyDefects in immune cell structures, such as T-cells can leave the patient vulnerable many infections that do not affect people with normal immune function 1 Lack of T-cell can result from hereditary conditions such as severe immune combined deficiency (SCID).

A common symptom of his disorder is repeated respiratory infections.

Humoral immune deficiency is associated with a condition called “hypogammaglobulinemia,” in which the body does not make enough of certain important kinds of antibody.

There are over 80 recognized primary immunodeficiency conditions they are generally labeled by the part of the immune system that is not working. Many of the conditions that cause immunodeficiency are rare diseases passed along from one or both parents. Primary immunodeficiencies involve defects within the immune system itself. Most cases of immunodeficiency are acquired (“secondary”), meaning they are not conditions the patient was born with, but were caused by an illness or toxin later on. Some people are born with defects in their immune system, which is called “primary” immunodeficiency. In some cases, immune deficiency can also affect the body’s ability to perform its natural function of attacking cells that may become cancerous.Ī person who has an immunodeficiency of any kind is said to be immunocompromised.Īn immunocompromised person may be particularly vulnerable to opportunistic infections, such as fungal and viral disorders as well as normal infections that could affect everyone.

Immune deficiency (or “ immunodeficiency”) is the term for any of a number of conditions in immune system loses part or all of its ability to fight infectious disease. The immune system is a network of highly specialized blood cells and other mechanisms in the body that fight off disease, whether it be infections from bacteria or viruses or illnesses that originate from within the body, such as cancer.
