IMID	Immune mediated inflammatory disease	Chita
immature reticulocyte fraction	IRF	Nataly­a Rovin­a
imms	immunisations	Ying
immune complex	An antibody bound to an antigen. Immune complexes are part of a normal immune response. However, when immune complexes accumulate in the blood, they can cause autoimmune disorders, infections, and malignancies.
immune reconstitution inflammatory syndrome (IRIS)	In HIV infection, an exaggerated inflammatory reaction to a disease- causing microorganism that sometimes occurs when the immune system begins to recover following treatment with antiretroviral (ARV) drugs. Immune reconstitution inflammatory syndrome (IRIS) occurs in two forms: "unmasking" IRIS refers to the flare-up of an underlying, previously undiagnosed infection soon after antiretroviral therapy (ART) is started; "paradoxical" IRIS refers to the worsening of a previously treated infection after ART is started. IRIS can be mild or life-threatening.

immune response	Actions of the immune system to defend the body against bacteria, viruses, or other substances that the body recognizes as foreign and harmful.

IRIS can be mild or life-threatening.
immune serum globulin	A solution of antibodies prepared for injection into a person's vein. Intravenous immunoglobulin (IVIG) is composed of antibodies removed from the blood of healthy donors and then pooled together and purified. IVIG is approved for use in children infected with HIV to reduce the risk of serious bacterial infections.
immune system	A complex network of specialized cells, tissues, and organs that recognize and defend the body from foreign substances, primarily disease-causing microorganisms such as bacteria, viruses, parasites, and fungi. Organs and tissues of the immune system, called lymphoid organs, include the bone marrow, spleen, thymus, and tonsils. Immune system cells include white blood cells, such as B lymphocytes (B cells) T lymphocytes (T cells) dendritic cells, and macrophages. HIV infection gradually destroys the immune system.
immune thrombocytopenic purpura	An autoimmune disorder in which the immune system destroys platelets. The destruction of platelets leads to abnormal blood clotting and easy or excessive bruising and bleeding. The exact cause of idiopathic thrombocytopenia purpura is unknown
immunity	Protection against disease caused by infectious microorganisms or by other foreign substances. There are two main types of immunity: innate and acquired.
immunization	Giving a vaccine to stimulate a person's immune response. Vaccination can be intended either to prevent a disease (a preventive vaccine) or to treat a disease (a therapeutic vaccine)
immunocompetent	When the body is able to produce a normal immune response.
immunocompromised	When the body is unable to produce an adequate immune response. A person may be immunocompromised because of a disease or an infection, such as HIV, or as the result of treatment with drugs or radiation.
immunodeficiency	Inability to produce an adequate immune response because of an insufficiency or absence of antibodies, immune cells, or both. Immunodeficiency disorders can be inherited, such as severe combined immunodeficiency; they can be acquired through infection, such as with HIV; or they can result from chemotherapy.
immunogenicity	The ability or the extent to which a substance is able to stimulate an immune response.
immunoglobulin	A protein produced by B lymphocytes (B cells) in response to an antigen. Antibodies bind to and help destroy antigens.
immunologic	Pertaining to the immune system.
immunologic failure	A type of HIV treatment failure. There is no consensus on the definition of immunologic failure. However, some experts define immunologic failure as the failure to achieve and maintain adequate CD4 counts despite viral suppression.
