    Tissue Engineering and Regenerative Medicine

    • Technology focuses on skin and connective tissue replacement.
    • Examples include: autologous cells for knee cartilage and artificial pancreas development (more than 20 years).

    The medicines of transplantation

    • Calcineurin inhibitors (cyclosporine) - blocks IL-2 (fewer killer T cells)
    • Antimetabolites (CellCept, Cytoxin) - depresses attacking cell replication in bone marrow and macrophages
    • Corticosteroids (prednisone) - blocks IL-2

    Psychosocial Aspects

    • Consider patients' terminal diagnosis until a donor/intervention is found.
    • Patients and loved ones experience challenging emotions during the waiting period.

    • Very serious reactions include fever, rash, gastrointestinal symptoms, and neuropathy.
    • High-dose corticosteroids and immunosuppression are treatments for GVHD.

    Immunosuppression

    • Long-term therapy can cause associated conditions: infection, diabetes, hyperlipidemia, cardiovascular disease, osteoporosis, steroid-induced myopathies, neuropathies, tremor, paresthesia, seizures, demyelinating polyradiculopathy, and quadriplegia

    Cancers due to Immunosuppression

    • Rate 3 times higher in transplant recipients.
    • Risk increases with immunosuppression amount, particularly in cardiac transplants.
    • Examples include skin cancer, Kaposi's sarcoma, and lymphomas.

    Post-exercise Considerations

    • Comparison of two patients and assessing how they are similar and different (Bob: 40, liver; Ron: 65, new knee).

    Post-transplant Exercise

    • Exercise improves cardiovascular function, strength, overall quality of life (QoL) and attenuates immunosuppression effects.

    Kidney, Bladder, Liver, Pancreas

    • Patients may differ in rehabilitation needs post-transplant based on specific organs/combinations.
    • Patients usually need reconditioning and strength training.
    • Watch for exercise intolerance, increased HR/SOB, or pallor during treatment.
    • Some specific considerations for transplants and organ function.

    Liver Transplant Procedure

    • 2-12 hours long
    • Very skilled surgeons and team
    • Surgical incision
    • Removes the old liver and replaces it with a donor liver
    • Reattaches all vessels and ducts
    • Closes abdominal cavity

    • Two practice recommendations (safe, tolerable, feasible, improving postoperative functional outcomes).
    • Pretransplant rehab is likely safe and can yield short-term functional benefits.
    • 50% of patients have pre-existing myocardial issues and other risk factors in heart function should be considered prior to treatment.
    • Early rehab reduces ICU stay lengths for liver transplant patients.

    Kidney Transplant

    • Common transplant, with 26,309 procedures in 2022
    • ~44,000 patients on the waitlist
    • 5-year survival rates are higher for living donors compared to deceased donors (78% without transplant, 88% with living donor, 78% with deceased donor).

    Kidney Procedure

    • Typically a surgical incision (U-shaped or Y-shaped) is performed
    • The surgical approach involves incisions in the inguinal ligament, skin, and rectus muscle

    Kidney and Exercise

    • Pre- and long-term rehabilitation is crucial for enhancing physical activity in kidney transplant patients.

    Kidney Transplant Rehab

    • Lacks significant findings due to a lack of randomized controlled trials.
    • Exercise training is proven safe for selective SOT candidates.
    • The effect of exercise training on capacity and quality of life remains unclear.

    Exercise (Post-transplant)

    • Rehabilitation programs vary based on the patient's diagnosis or type of organ transplanted.
    • Attention should be paid to physical limitations, fear of negative effects, low expectations, and self-confidence for effective intervention.
    • Moderate exercise is recommended with avoidance of overtraining/system specific concerns.

    Exercise Programs (following transplant)

    • Combined aerobic and strength training programs (3+ months) are most effective in reducing blood pressure.
    • Aerobic and combined resistance/aerobic training (12+ weeks) may increase lean muscle mass but haven't shown consistent impact on fat mass or body weight/BMI.
    • Exercise programs with aerobic or combined aerobic/resistance exercise(duration between 3-12 months, home-based or supervised) are consistently shown to improve workload and muscle strength in transplant recipients.

    Treatment Take-Aways for SOT

    • SOT numbers are growing, and preconditioning is helpful.
    • Falls and fall risks are a significant liability concern for transplant patients.
    • Exercise is generally safe post-transplant.
    • Acute, subacute, and long-term adjustments are essential in patient care.

    Treatment Protocol

    • Individualized assessment protocols should be developed for patients
    • Factors impacting patients should be evaluated during treatment.
    • While treating patients after transplant can be challenging, it isn't necessarily daunting.
