1

AIDS - related complex (ARC)

Early stage of human immunodeficiency virus (HIV) infection in which mild symptoms of infection are present, including lymphadenopathy fatigue night sweats weight loss and diarrhea

2

Acquired immunodeficiency syndrome

Later stage of HIV when the cells of the immune system lose the ability to fight off infection

3

Allergist

Physician specializing in diagnosis and treatment of allergies

4

Allergy

Hypersensitivity to a common substance in environment, food or medication

5

Anaphylactic shock

Life threatening condition resulting from severe allergic reaction causing cardiovascular and respiratory problems; may be triggered by bee stings medication or certain foods

6

Antihistamine

Medication which blocks the release of histamine during an allergic reaction

7

Antinuclear antibody titer ANA

Blood test which determines number of antibodies against cell nuclei present in bloodstream; elevated in autoimmune conditions

8

Autoimmune disease

Disease resulting from body’s immune system attacking its own cells as if they were pathogens

9

Corticosteroids

Hormones produced by adrenal cortex, used as medication to treat autoimmune diseases due to their very strong anti-inflammatory properties

10

Cytotoxic cells

Cells capable of physically attacking and killing pathogens or diseased cells

11

Elephantiasis

Results from blockage of lymphatic vessels that cause extreme edema

12

Enzyme linked immunosorbent assay (ELISA)

Blood test for antibody to aquired immunodeficiency syndrome virus; positive result means the person has been exposed to the virus

13

Hives

Common name for appearance of wheals

14

Hodgkin disease (HD)

Cancer of lymphatic cells found in lymph nodes, also called Hodgkin’s lymphoma

15

Immunodeficiency

Having an immune system that is unable to respond properly to pathogens; immune compromised

16

Immunosuppressant

Medication to block certain actions of immune system; used to prevent rejection of transplanted organ

17

Inflamation

Tissue response to injury; characterized by redness, pain, swelling, and feeling hot to touch

18

Kaposi sarcoma

Type of skin cancer often seen in patients with AIDS; consits of brownish purple papules that begin in skin and spread to internal organs

Genetic condition of children born with nonfunctioning immune system who are often forced to live in sealed sterile rooms

26

Systemic lupus erythematosus (SLE)

Autoimmune disease in which immune system attacks connective tissue throughout body such as joints and skin

27

Urticaria

Severe itching usually associated with hives, usually seen in allergic reactions to food, strees, or medication

28

Vaccination

Exposure to weakened pathogen to stimulate immune response and antibody production to give future protection against full blown disease: immunization

29

Western blot test

Blood test to detect various antibodies in bloodstream such as HIV, considered more precise than ELISA
