What are the most common diseases of immune deficiency?
immune deficiency disease occurs when the person's immune system is defective or impaired. This results in the inability of the body to properly fight disease and infection. There are different types of immunodeficiency disorders that are divided into two main types. These types of immune deficiency disease include congenital immunodeficiency disorders that are considered primary and obtained by immunodeficiency disorders that are secondary. The Most Common Immune Deficiency Diseases Include Common Variable Immunodeficiency (CVID), Sever Combined Immunodeficiency (SCID), Acquired Immunodeficiency Syndrome.
altohough Acquired immunodeficience Disorders are More Common Than Congenital Disorders, The Congenital Disorders Are Present in the Body at the Time of Birth. They are therefore the result of genetic defects and are considered congenital. These diseases of immune deficiency may include scid and cvid like Forms pneumoniaUs and flu. Chemotherapy and radiation can also lead to immunodeficiency disorders. The acquired immunodeficiency disorders are most commonly found due to other diseases or complications of other disorders.
types of immune deficiency diseases that lead to acquired immunodeficiency disorders include human immunodeficiency virus (HIV) that causes AIDS. Other disorders include malnutrition, cancer types, measles, chickenpox, chronic hepatitis and bacterial and fungal infections. SARS is another form of acquired immunodeficiency disorder that appeared in China and Canada in 2003.
The primary type of immune deficiencies are congenital immunodeficiency disorders and occur at defect either in B-cells-called b-lymphocytes that are produced in bone marrow-T-cells or T-lymphocytes that ripen in the thymus. Congenital disorders can also occur when the defects nachThey are in B and t cells. There are several types of primary immunodeficiency and common is Bruton's Agammaglobulinemia, also known as Agammaglobulinemia associated with X (XLA).
type of humoral or specific immune disorders, XLA occurs when a defect or absence of B-cells, where the immune system is unable to produce antibodies. People suffering from this disorder have been the victim of skin, neck, ear and lung infections. Found only in men, this is caused by a defect in chromosome X.
Hyper-Igm syndrome is another humoral immunodeficiency that occurs and is the result of defects in B-cells and repair deoxyribonucleic acid (DNA). It is found in other antibodies such as CVID. Another type of B-cell deficiency, immunoglobin production in CVID is reduced and the antibody response is disturbed. This disorder develops at the age of 10-20 years and people who have Cvid suffer from several infections and may experience rheumatoid arthritis and anemia. Finally, they could also develop cancer.
Often fatal, T-lymphocyte deficiencies occur when T-cells do not betray, resulting in an immune system that is particularly susceptible to infection from viruses, bacteria and fungi. Lack of T-cells, DigEorge syndrome develops on the fetus when a certain chromosome is removed. Children are often born without a thymus or those that are insufficiently developed and often have physical abnormalities such as wide eyes and low-sticked jaws or ears.
Another congenital immunodeficiency is when both B-cells and T-cells are affected. Severe combined immunodeficiency (SCID) is caused by defective B and T lymphocytes and worsens cellular immune responses. Discovered in the first year, Children, which has a Scid, suffers from fungal infections such as thrush, and without bone marrow transplantation, they die during the first year of life.
