Immuno Drugs Flashcards
Acquired Immunity: 2 subtypes
Natural and Artificial
Acquired Immunity - Natural: 2 subtypes and their meanings
- Actively acquired: Having the disease
2. Passively acquired: Antibodies through placenta or breast milk
Acquired Immunity - Artificial: 2 subtypes and their meanings
- Actively acquired: Antibodies produced through immunization vaccine or toxoid
- Passively acquired: Injection of antibodies (immunoglobulins)
Hepatitis B immuneglobulin: immunity type
Artificial passive immunity
MMR: Buzzword
Buzz word: Artificial active immunity
Indicated at 12 mos.
Contraindicated in pregnancy (because it’s a live vaccine)
Immunosuppressants and Immunomodulators
Immunosuppressant drugs such as corticosteroids suppress T-cells
Lab tests done before giving immunosuppressant drugs (4)
- BUN and Cr
- CBC
- Platelets
- Hepatic enzymes
Agents used during organ transplants: Cyclosporine
MOA: Binds to cyclophillin and leads to decrease of calcineurin —> inhibition of IL-3, IL-3, IFN-gamma
Usually combined with corticosteroids
Adverse effects: Nephrotoxicity and Gingival hyperplasia
Agents used during organ transplants: Azathioprine
MOA: Converted to 6-mercaptopurine –> immunosuppression
Adverse: Leukopenia, thrombocytopenia, hepatotoxicity
Agents used during organ transplants: *Muromonab-CD3
Monoclonal ab to CD-3 glycoprotein
Buzzword: Acute renal transplant rejection
*Must administer methylprednisone before IV muromonab-CD3 to precent cytokine release syndrome
Agents used during organ transplants: Sirolimus (rapamycin)
Macrolide Antibiotic
Mamalian Target of rapamycin (mTOR inhibitor)
MOA: Forms a complex with FK12-binding protein and inhibits T-cell proliferation
Adverse: Myelosuppression
Metabolized by CYP450
Agents used during organ transplants: Tacrolimus
Macrolide Antibiotics
Tacrolimus & Cyclosporine bind to immunophilins (Cyclophilin and FK506-binding protein)
MOA: Calcineurin inhibitors of IL-2
Indicated in renal and liver transplants
Ointment rx of atopic dermatitis and psorioasis
Agents used during organ transplants: Mycophenlate
MOA: Inhibits de novo syntheisis of purines
Used in combo with cyclosporine
Agents used during organ transplants: Thalidomide
Inhibits angiogenesis
Teratogenic cause phocomelia and congenital malformation
Drug prevents vascular growth during fetal limb development
Immunosuppressant and immunostimulant
Inhibits IL-2, TNF and other cytokines
Clinical use: Cancer, TB, leprosy, erythema, nodosum leprosum, AIDS-associated wasting syndrome (Cachexia)
Agents that serve to STIMULATE immune response: Buzzword, Indications, and Adverse
Buzzword: IV and IM immunoglobulins
Indications: Rx of congenital agammaglobulinemia, AI disease, and Guillan-Barre syndrome
Adverse: Hypersensitivity rxns
Rh Incompatibility: If mom ab screen is Rh-
Answer Rhogam at 28 weeks of pregnancy and 72 hours post partum if baby is Rh+
Rhogam
Human IgG to red cell Rho(D) antigen. Neutralizes Rh+, so mom will not make ab (making it safe for second pregnancy)
