acquired immunodeficiency syndrome (aids)
grp of clinical signs and symptoms associated with suppression of immune system and marked by opportunistic infections, secondary neoplasms, and neurologic problems. caused by hiv which destroys helper t cells
candidiasis
yeast like fungus, normally present in mouth, skin, intestine, vagina, overgrows and causes infection
cryptococcal infection (crypto)
yeast like fungus, causes brain, blood, and lung infections
cryptosporidiosis
parasitic infection of GI tract, brain, spinal cord
cytomegalovirus (cmv) infection
virus causes enterits and retinits (inflammation of retina at back of eye. found in saliva, semen, cervical secretions, urine, feces, blood, breast milk, but causes disease only when immunocompromised
herpes simplex
viral infection causes small blisters on skin of lips, nose, genitals. can cause encephalitis
histoplasmosis (histo)
fungal infection caused by inhalation of contaminated dust. causes fever, chills, lung infection
mycobacterium avium-intracellare (MAI) complex infection
bacterial disease manifesting with fever, malaise, night sweats, anorexia, diarrhea, weight loss, lung and blood infections
pneumocystis/pneumonia (pcp)
unicellular organism causes lung infection with fever, cough, chest pain.
toxoplasmosis (toxo)
parasitic infection involving cns and causing fever, chills, visual disturbances, confusions, hemiparesis (slight paralysis in body half), seizures
tuberculosis (tb)
bacterial disease involving lungs, brains, and other organs. signs and symptoms are fever, cough, loss of weight, anorexia, blood in sputum.
allergy
abnormal hypersensitivity acquired by exposure to antigen
lymphoma
malignant tumor of lymph nodes and lymph tissue
multiple myeloma
malignant tumor of bone marrow cells
thymoma
tumor of thymus gland
allergen
substance capable of causing allergy
anaphylaxis
exaggerated/unusual hypersensitivity to foreign protein or substance
atopy
hypersensitive or allergic state involving inherited predisposition
CD4+ cells
helper t cells that carry the cd4 protein antigen on surface. hiv binds to cd4 and infects and kills t cells. aids patients have inadequate number of cd4+ cells.
hodgkin lymphoma
malignant tumor of lymphoid tissue in spleen and lymph nodes
hiv (human immunodeficiency virus)
causes aids
kaposi sarcoma
malignant lesion associated with aids, comes from lining of capillaries; red, purple, brown, or black skin nodules.
non hodgkin lymphomas
group of malignant tumors involving lymphoid tissue
opportunistic infections
infectious disease associated with aids, occur because hiv infection lower’s immune system ability
protease inhibitor
drug that treats aids by blocking production of protease, enzyme that creates new pieces for hiv
reverse transcriptase inhibitor (rti)
drugs that treats aids by blocking reverse transcriptase, enzyme needed to make copies of hiv
wasting syndrome
weight loss, decrease in muscle strength, appetite, mental activity; associated with aids
cd4+ cell count
measures number of cd4+ t cells (helper t cells) in blood of patient with aids
elisa
screening test to detect anti hiv antibodies in blood
immunoelectrophoresis
test that separates immunoglobulins (IgM, IgG, IgE, IgA, IgD)
viral load test
measurement of amount of aids (hiv) in blood
