immunodeficiency Immunodeficiency disorders are a group of disorders in which part of the immune system is missing or defective. Therefore, the body's ability to fight infections is impaired. As a result, the person with an immunodeficiency disorder will have frequent infections that are generally more severe and last longer than usual.

immunity 1. the condition of being immune; security against a particular disease; nonsusceptibility to the invasive or pathogenic effects of microorganisms or helminth parasites or to the toxic effect of antigenic substances. Called also functional or protective immunity.

Conditions & Treatments Symptoms, Diagnosis, Treatment & Management. According to the leading experts in immunology, when part of the immune system is either absent or not functioning properly, it can result in an immune deficiency disease. When the cause of this deficiency is hereditary or genetic, it is called a primary immunodeficiency disease (PIDD).

What Are Immune Deficiency Disorders? Common variable immune deficiency (CVID). Due to a genetic defect, the immune system produces too few antibodies to effectively fight infections. Children with CVID typically have frequent infections of the ears, lungs, nose, eyes, and other organs.

Antibody deficiencies Background. 1  Common variable immunodeficiency (CVID), also called hypogammaglobulinemia or adult-onset hypogammaglobulinemia, is a relatively common primary immune deficiency. The disorder is characterized by a lack of antibody-producing B-cells or plasma cells, low levels of most or all immunoglobulin isotypes and recurrent bacterial infections.

Overview Selective IgA deficiency is an immune system condition in which you lack or don't have enough immunoglobulin A (IgA), a protein that fights infection (antibody). Most people with selective IgA deficiency don't have recurrent infections.

IgA Deficiency IgA deficiency is a defect in the immune system characterized by an inadequate amount of the antibody class known as immunoglobulin A (IgA).Antibodies are large proteins produced by the body to fight infections caused by invaders, such as bacteria, viruses, fungi, parasites, and other foreign agents.The immune system responds to the protein component (antigens) of these invaders by producing large quantities of specific antibodies, including IgA.gA deficiency is a defect in the immune system characterized by an inadequate amount of the antibody class known as immunoglobulin A (IgA).

Immune disorder An immune disorder is a dysfunction of the immune system. These disorders can be characterized in several different ways: 1  By the component(s) of the immune system affected.2  By whether the immune system is overactive or underactive.3  By whether the condition is congenital or acquired.n immune disorder is a dysfunction of the immune system.

Antibody deficiencies Antibody deficiencies, also called immunoglobulin deficiency syndromes, are immune system disorders that are characterized by low or absent levels of immunoglobulin in the blood. Immunoglobulins (Ig) are antibodies that play an essential role in the body's immune system.

IgG Deficiencies What are IgG deficiencies? An IgG deficiency is a health problem in which your body doesn’t make enough Immunoglobulin G (IgG). People with IgG deficiency are more likely to get infections. When your body feels it is under attack, it makes special proteins called immunoglobulins or antibodies. These antibodies are made by the plasma cells.

- In cases of immune system over activity, the body attacks and damages its own tissues (autoimmune diseases). Immune deficiency diseases decrease the body's ability to fight invaders, causing vulnerability to infections.

Immune disorder Immune disorder. An immune disorder is a dysfunction of the immune system. According to the International Union of Immunological Societies, more than 150 primary immunodeficiency diseases (PIDs) have been characterized. However, the number of acquired immunodeficiencies exceeds the number of PIDs.

- Antibody deficiencies, also called immunoglobulin deficiency syndromes, are immune system disorders that are characterized by low or absent levels of immunoglobulin in the blood.Immunoglobulins (Ig) are antibodies that play an essential role in the body's immune system.he antibodies are present in the bloodstream or bound to the outer surfaces of B-cells or plasma cells. There are five classes of immunoglobulins: IgA, IgD, IgE, IgG, and IgM. Patients who have antibody deficiencies may have reduced or absent levels of one or more types of immunoglobulin.

Primary Immune Deficiency (PID) Primary immune deficiency (PID) is the name given to chronic illnesses caused by hereditary or genetic defects in the immune system.There are over 150 forms of PID. Some are mild, some are severe. The immune system protects our bodies from germs such as bacteria and viruses that cause infections.rimary immune deficiency (PID) is the name given to chronic illnesses caused by hereditary or genetic defects in the immune system.

In 1853, American inventor Elisha Otis demonstrated a freight elevator equipped with a safety device to prevent falling in case a supporting cable broke.

Common Variable Immune Deficiency Common Variable Immune Deficiency. Common Variable Immune Deficiency (CVID) is one of the most frequently diagnosed primary immunodeficiencies, especially in adults, characterized by low levels of serum immunoglobulins and antibodies, which causes an increased susceptibility to infection.
