Cards

Term
Prednisone (immuno)
Definition
Oral corticosteroid with various uses which primarily reduces circulating lymphocyte levels

cause Cause
GROWTH RETARDATION
CUSHINGS
PEPTIC ULCERS
AVASCULAR NECROSIS
HIRUSITISM
Term
Prednisolone (immuno)
Definition
IV corticosteriod used in the prophylaxis and management of acute rejection in organ transplants

GREATER THAN 75% SAVED IN REJECTION

Primarily reduces circulating lymphocyte levels and cytokine production

hepatic metabolism
Term
Cyclosporine
Definition
Calcineurin inhibitor via IMMUNOPHYLIN A (inhibits NFAT --> inhibit cytokines--> inhibits lymphocyte)

Prophylaxis organ rejection during induction and maintenance PREVENTATIVE ONLY and treat inflammatory disorders

slow incomplete absorbtion, metabolized via CYP450

NEPHROTOXIC, GINGIVAL HYPERPLASIA, HIRSITUISM
Term
tacrolimus
Definition
Calcineurin inhibitor via FKB-12 (inhibits NFAT --> inhibit cytokines--> inhibits lymphocyte)

Prophylaxis organ rejection during induction and maintenance PREVENTATIVE ONLY and treat inflammatory disorders

slow incomplete absorbtion, metabolized via CYP450

NEPHROTOXIC, HYPERGLYCEMIC

1000X stronger than cyclosporin
Term
Pimecrolimus
Definition
Calcineurin inhibitor via FKB-12 (inhibits NFAT-->inhibits IL2/4-->inhibits lymphocytes)

used to treat mild to moderate atopic dermatitis

Not really used systemically for adverse effects
Term
azothioprine
Definition
Inhibits glutamine PRPP amidotransferase in formation of IMP and Purine salvage pathway therefore ANTIMETABOLITE (IMP imposter)

prophylaxis of organ reject during induction and maintainence PREVENTATIVE ONLY

Converted to 6MP in liver by XANTHINE OXIDASE THEREFORE AVOID ALLOPURINOL

only 50% bioavailable

POLYMORPHISM OF TPMT = toxicity

leukopenia, thrombcytopenia
Term
mycophenolate
Definition
Inhibits IMP dehydrogenase (stops GMP formation)

used in prophylaxis organ rejection PREVENTATIVE ONLY

converted to acid, 95% bioavailable with ENTEROHEPATIC RECYCLING THEREFORE AVOID CHOLECYSTIRAMINE and MG containing compounds

similar side effects of azothioprine
Term
sirolimus
Definition
FBK-12 binder inhibits mTOR

PREVENTATIVE AGAINST REJECTION ONLY

locks cells in G1 phase; metabolized in liver

HYPERCHOLESTEROLEMIA
Term
Anti-thymocyte immunoglobulin (ATGAM)
Definition
polyclonal antibody prepared from hyperimmune serum of a variety of mammals

Can lead to leukopenia and thrombcytopenia and CRS

ATGAM from horses

Both bind to T cell surface proteins and lead to depletion of T and B cells

Good for induction and tx rejection of solid organ transplants (esp. kidney)

NEVER MAINTAINENCE
Term
Muromonab-cd3
Definition
Mouse hybridoma produced antibody to T-cell marker

potential severe CYTOKINE RELEASE SYNDROME side effect (tx steroid) and/or CNS problems

Leads to T cell depletion and impaired T-cell receptors

Good for induction and tx rejection of solid organ transplants

NEVER MAINTAINENCE and HIGHER RISK INFECTION
Term
Daclizumab
Definition
Mouse/human chimeric protein that binds to the alpha subunit of IL2 thereby preventing T/B differentiation and proliferation

T1/2>Basiliximab

Good for induction and tx rejection of solid organ transplants ESPLUNG

NEVER MAINTAINENCE
Term
basiliximab
Definition
Humanized monoclonal antibody that binds to the alpha subunit of IL2 thereby preventing T/B differentiation

Good for induction and tx rejection of solid organ transplants ESP LUNG

NEVER MAINTAINENCE
Term
infliximab
Definition
mouse/human chimeric monoclonal AB against both soluble and membrane bound TNFa

this dampens the production of cytokines and other inflammatory factors

used to treat a variety of inflammatory and autoimmune disorders
Term
etanercept
Definition
Fusion protein of TNFa receptor and IgG1 against both soluble and membrane bound TNFa

this dampens the production of cytokines and other inflammatory factors

used to treat a variety of inflammatory and autoimmune disorders
Term
Interferon gamma
Interleukin 2
IL-4
Definition
INFgamma = activates macrophage
IL2 = proliferation of B and T cells
IL4 = secreted Th to prolif B
Term
Rho(D)immunoglobulin Rhogam
Definition
Antibody against the Rh(D) antigen on red blood cells derived from human plasma

prevents sensitization of mother to RD antigen
Term
CI inhibitors interactions
Definition
increase CYP3A4 inhibition
Antibiotics
antivirals
antifungals
cardiac
