- Avoid complications
- Patient and graft survival
- Patient adherence
7
Q

A
- Desensitization
- Induction
- Maintenance
8
Q
Least to most immunogenic organs
A
- Liver
- Kidneys
- Pancreas
- Heart
- Lungs
- Colon
9
Q
Induction Therapy Goal
A
- Prevent early acute graft rejection
- Decrease T cells and/or B cells for months
10
Q
Drugs that can be used for induction therapy
A
- Basiliximab
- Antithymocyte globulin
- Alemtuzumab
11
Q
Basliximab (Simulect) Mechanism of Action
A
- Blocks T cell proliferation
- Via interleukin 2 (IL-2)
- Anti CD25 antibodies
- Used in lowest immunologic risk patients
12
Q
Antithymocyte Globulin (Thymoglobulin) Mechanism of Action
A
- Binds to T cell surface antigens
- leading to depletion of T cells
- Used in moderate to high immunologic risk
- Increased risk of CMV, BKV, and PJP
13
Q
Alemtuzumab (Campath) Mechanism of action
A
- Binds to CD52 on T cells, B cells, NK cells, and monocytes/macrophages
- “AIDs” in a bottle
- 1+ year for CD4/8 counts to recover
- Associated with many opportunistic infections
14
Q
Maintenance Therapy Goal
A
- Prevent graft rejection
- Life long immunosuppression
15
Q
Drugs that can be used for Maintenance Therapy
A
- Corticosteroids
- Calcineurin inhibitors
- Antimetabolites
- mTOR inhibitors
16
Q
Corticosteroids mechanism of action
A
- Inhibit cytokine gene expression
- Modify lymphocyte distribution and function
- Anti inflammatory
ex. prednisone 5-10mg/day
