People with common variable immunodeficiency may have a chronic cough, cough up blood, or have difficulty breathing (due to frequent sinus and lung infections) and may have diarrhea. common variable immune deficiency. Description. Common variable immune deficiency (CVID) is a disorder that impairs the immune system. People with CVID are highly susceptible to infection from foreign invaders such as bacteria, or more rarely, viruses and often develop recurrent infections, particularly in the lungs, sinuses, and ears. Pneumonia is common in people with CVID. Common variable immunodeficiency is a primary immunodeficiency disorder. It is usually diagnosed between the ages of 20 and 40 but may appear earlier or later in life. The number of B cells is usually normal, but the cells do not mature and thus cannot produce immunoglobulins. Common variable immunodeficiency (CVID) is a rare immune deficiency characterized by low levels of serum IgG, IgA, and/or IgM, with a loss of Ab production. The diagnosis is most commonly made in adults between the ages of 20 and 40 years, but both children and much older adults can be found to have this immune defect. These individuals may have normal numbers of the cells that produce antibodies (B lymphocytes), but these cells do not function properly. The name CVID reveals information about the condition: Common: CVID is a relatively common type of PI found in about 1 in 25,000 persons. Common variable immune deficiency (CVID) is considered to be a collection of primary immune deficiency diseases characterized by reduced serum levels of IgG, IgA, and/or IgM, with reduced or absent specific Ab production. (See also Overview of Immunodeficiency Disorders.) Common variable immunodeficiency is an immunodeficiency disorder characterized by very low antibody (immunoglobulin) levels despite a normal number of B cells (lymphocytes). Symptoms of CVID. Some people with CVID have symptoms as young children, while many others may not develop symptoms until their 20s or 30s—or even later. The most common symptoms are recurring infections involving the ears, sinuses, nose, bronchi (breathing tubes), and lungs (respiratory tract). Common Variable Immune Deficiency (CVID) Definition of CVID. People with CVID have decreased levels of antibodies (immunoglobulins) in the blood and are therefore more likely to get infections. Antibody levels may be low (hypogammaglobulinemia) or absent (agammaglobulinemia). Hypogammaglobulinemia, acquired as a Disease.
