According to the International Union of Immunological Societies, more than 150 primary immunodeficiency diseases (PIDs) have been characterized. [2] However, the number of acquired immunodeficiencies exceeds the number of PIDs. [3] It has been suggested that most people have at least one primary immunodeficiency. [4]
Adult-onset immunodeficiency syndrome is a type of immunodeficiency. It is linked to vulnerability to disseminated infections brought on by opportunistic pathogens. People with this condition have increased levels of anti-interferon-gamma autoantibodies. These particular immune system proteins mistakenly target an individual's own tissues.
It can be mediated by insufficient number or function of B cells, the plasma cells they differentiate into, or the antibody secreted by the plasma cells. [7] The most common such immunodeficiency is inherited selective IgA deficiency , occurring between 1 in 100 and 1 in 1000 persons, depending on population.
Treatment for combined immunodeficiencies with defects in antibody production primarily consists of immunoglobulin replacement therapy. [1] Susceptibility to infections is an important feature of combined immunodeficiencies and influences patients' clinical evolution; as a result, antimicrobial prophylaxis is frequently used to prevent ...
Immunodeficiency, also known as immunocompromisation, is a state in which the immune system's ability to fight infectious diseases and cancer is compromised or entirely absent. Most cases are acquired ("secondary") due to extrinsic factors that affect the patient's immune system.
Severe Combined Immune Deficiency; Other names: Alymphocytosis, Glanzmann–Riniker syndrome, Severe mixed immunodeficiency syndrome, and Thymic alymphoplasia [1] David Vetter, a child born in 1971 with severe combined immunodeficiency (SCID). Specialty: Immunology Treatment: Bone marrow transplantation and prophylaxis against infection: Medication
T cell deficiency is a deficiency of T cells, caused by decreased function of individual T cells, it causes an immunodeficiency of cell-mediated immunity. [1] T cells normal function is to help with the human body's immunity, they are one of the two primary types of lymphocytes (the other being B cells).
Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) The goals in this area are finding a cure for HIV-infected individuals; developing preventive strategies, including vaccines and treatment as prevention; developing therapeutic strategies for preventing and treating co-infections such as TB and hepatitis C in HIV ...
