1
Q

main uses for immunosuppressant therapy

A

to counteract an inappropriate immune response like an autoimmune disorder

Q

nursing considerations in steroid therapy

A

DO NOT… abruptly stop therapy

DO… give according to circadian rhythm, give with food, protect patient from injury/infection, monitor blood glucose and fluid retention

Q

purpose of biological response modifiers

A

therapeutic meds that will alter a pt’s immune response mainly to malignant cells

22
Q

types of biological response modifiers

A

hematopoietic agents, interferons, monoclonal antibodies, interleukins

23
Q

hematopoietic agent MOA

A

stimulate colony cells in bone marrow to restore blood components

24
Q

hematopoietic agent uses

A

treat bone marrow suppression in cancer patients, ESRD and severe immunocompromised

anemic pts = stimulate RBCs
neutropenic pts = stimulate WBCs
thrombocytopenic pts = stimulate platelets

25
hematopoietic agent medications for anemia
epoetin, darbepoetin
26
hematopoietic agent medications for neutropenia
filgrastim (stimulate neutrophils), sargramostim (stimulate granulocytes and macrophages)
27
hematopoietic agent medications for thrombocytopenia
oprelvekin- promote platelets
28
nursing considerations for hematopoietic agents
assess for S&S of anemia, neutropenia, and thrombocytopenia safety precautions (anemic = weak and dizzy, lead to falls; thrombocytopenic = bleed and bruise easy, protect from everything)
29
interferon medications MOA
regulate immune functions, slows cell proliferation, and inhibits virus replication
30
interferon med usage
chronic viral illnesses (Hep C, MS, cancer); often used in combo with antiviral
31
monoclonal antibody MOA
block TNF or interleukins to inhibit joint destruction and inflammation
32
monoclonal antibody uses
cancer treatment, progressive autoimmune disease (RA, Crohn's, ulcerative colitis)
33
monoclonal antibody meds
-mab meds (adalimumab, trastuzamab)
34
TNF Receptor Antagonist med types
etanercept- severe RA BCG vaccine- TB vaccine to treat bladder cancer Retinoid receptor agonist (bexarotene/tretinoin)- skin cancer and other types
35
contraindication in TNF receptor antagonist
moderate to severe heart failure pts
36
interleukins MOA
cytokines that exact MOA is unknown but enhance the signal to T cell growth and cytotoxic lymphocytes
37
interleukins use
severe RA, cancer treatment (renal, malignant melanoma, and leukemia)
38
interleukin meds for cancer treatment
aldesleukin (IL 2) and denileukin
39
interleukin meds for RA and neonates
anakinra (IL 1 receptor antagonist)
40
what are DMARDs
disease modifying antirheumatic drugs
41
DMARD use
prevent progression of RA
42
DMARD contraindication
pts with serious infections
43
non biological DMARDs
methotrexate (RA and sickle cell anemia), hydroxychloroquine (slows immune response)
44
biological DMARDs
given to pts that do not respond to methotrexate -mab drugs -tofacitinib may use for psoriasis, ulcerative colitis, etc
45
methotrexate MOA
chemotherapy agent that decreases inflammation by increasing adenosine levels
46
MTX ADRs
anemia and pulmonary fibrosis
47
MTX is always taken with...?
1 mg folic acid qd
48
hydroxychloroquine MOA
antimalarial agent that inhibits RF and early inflammatory cell response
49
hydroxychloroquine ADRs
irreversible retinal damage and blindness
50
sulfasalizine
reduces redness and inflammation; often used in combo with other treatments or steroids
51
Janus Kinase Inhibitor
tofacitinib; last resort DMARD
52
BBW on JAK Inhibitor
serious infection and malignancy; infections can lead to hospitalization or death
