Once a patient reaches a certain T-Cell counter deificency county it is later classified as the syndrome AIDS.
allergen
a substance that produces an allergic reaction in an individual.
anaphylaxis
Related Term: Anaphylactic Shock
a severe response to an allergen in which symptoms develop quickly, and without help, the Pt can die with a few minutes
- some Pt will have an emergency Epi pen or intervening relieving agent
antibiotics
a medication that is capable f inhibiting the growth of or killing harmful pathogenic bacteria/microorganisms
Can effect healthy flora/gut bacteria
Opposite Term: Probiotics
antibody
a disease fighting protein created by the immune system in response to the presence of a specific antigen.
antifungal
an agent that destroys or inhibits the growth of fungi
antigen
any substance that the body regards as foreign.
antigen-antibody reaction
The binding of antigens to antibodies.
autoimmune disorder
Any chacrecterized condition/disease where the Pt’s own immune system will produce antibodies against it’s own tissue and cells. Mistaking healthy cells, tissue, or organs for harmful antigens.
bacilli

carcinoma
a malignant tumor that occurs in epithelial tissue
carcinoma in situ
a malignant tumor in its original position that has not yet distributed or invaded to surrounding tissues.
complement system
a group of proteins that normally circulate in the blood in an inactive form. When needed, these cells complement the ability of antibodies to eard off pathogens by combining ith them to dissolve and remove pathogenic bacteria and other foreign cells.
cytokines
a group of proteins such as interferons and interlukins released primarily by the T cells thatact as intracellular signals to begin the immune response.
cytomegalovirus
a group of large herpes-type viruses found in most body fluids and most often causing an infection without signs or symptoms. Can acuse a serious illness when the individual has a weakened immune system or when passed from mother to unborn child.
cytotoxic drug
medication that kills or damages cells.
ductal carcinoma in situ
breast cancer at its earliest stage before the cancer has broken through the wall of the milk duct.
hemolytic
describes the function of destroying worn-out erythrocytes (RBC) and releasing their hemoglobin for reuse.

an acute viral inection cahrecterized by painful skin eruptions that follow the underlying route of the inflamed nerve.
Hodgkin’s Lymphoma
a malignancy of the lymphatic system taht is distinguished from non-Hodgkin’s lymphoma by the resence of large, cancerous lymphocytes.
human immunodefieciency virus
(AKA) HIV
a bloodborne infection in shich the virus damages or kills the healthy Tcells of the immune system.
immunoglubulins
Bind with specific antigens in the antigen-antibody response
immunosepressant
a sustance that prevents or reduces the body’s normal immune response
immunotherapy
a treatment of disease by either stimulating or repressign the immune response.
infectious mononucleosis
an infection caused by the Epstein-Barr virus (EBV) that is characterized by fever, a sore throat, and enlarged lymph nodes
infiltrating ductal carcinoma
Breast cancer that starts in the milk ducts, breaks through the wall of the duct, and invades the surrounding fatty breast tisue; AKA: invase ductal carcinoma
interferons
produced in response to the presence of antigens, particullarly viruses or tumor cells. They navigate the immune system, fight viruses, and signal other cells to increase their defenses
lymphadenopathy
any disease process affecting a lymph node or nodes
lymphangioma
a benign tumor formed by an abnormal collection of lymphatic vessels due to a congenital malformation of the lymphatic system
lymphedema
swelling due to the abnomral accumulation of lymph fluid within the tissues

lymphoma
a general term applied to malignancies affecting lymphoid tissues
