Test Your Knowledge on Pharmacotherapy in Solid Organ Transplantation

Solid Organ Transplantation Pharmacotherapy

• Antibody induction therapy is not universal for all solid organ transplants.

• Antibody induction therapy ranges from lowest use in liver transplant recipients (31.1%) to highest use in pancreas recipients (90.4%).

• Induction agents such as Anti-Thymocyte Globulin and Alemtuzumab profoundly deplete T-Cells.

• Basiliximab reduced the incidence of acute rejection episodes in renal allograft recipients.

• The introduction of the CNIs significantly improved the outcomes of solid-organ transplantation in terms of patient and graft survival.

• Tacrolimus has equivalent efficacy to cyclosporine as primary immunosuppression.

• Monotherapy with CNIs has been described, but is rarely used due to a higher incidence of rejection.

• Sirolimus had a delay to first biopsy-confirmed acute rejection episodes in kidney transplant patients compared to azathioprine.

• Corticosteroids have been used in immunosuppressive regimens since the first human transplantations and continue to be used today.

• Studies suggest that corticosteroids may have less of a role in maintenance immunosuppression in the future.

• A steroid-free maintenance immunosuppressive protocol in kidney transplant recipients had similar rates of patient and graft survival, with lower incidence of rejection and weight gain.

• Patients in the steroid-free group required therapy for anemia more frequently.Induction and Maintenance Immunosuppression Strategies in Renal Transplantation

• A study by Rajab et al. compared steroid-free induction with thymoglobulin, sirolimus, Neoral and prednisone taper over five days to a comparator group receiving basiliximab, Cellcept, Neoral, and prednisone taper over one year.

• The study found a lower incidence of acute rejection in the steroid-free group (4.9%) compared to the comparator group (9.4%), with a lower rate of graft loss due to rejection (0.7% vs. 1.8%).

• Weir et al. conducted a study on CNI-sparing strategies, reducing or discontinuing CNI with the addition or continuation of MMF and low-dose steroids.

• The study found that CNI withdrawal patients had the most improvement in the slope of decay of renal function or lack of deterioration (72.2%), followed by the reduced-dose CSA group (54.4%) and the reduced-dose tacrolimus group (40%).

• Vincenti et al. conducted a study on complete CNI avoidance, using daclizumab x 5 doses, MMF 3 gm/day for the first 6 months and 2 gm thereafter, with conventional corticosteroid therapy.

• The study found a higher rate of biopsy-proven rejection during the first 6 months post-transplant (48% vs. 26.2%) compared to a similar regimen with CNI.

• Ekberg et al. found that the rates of biopsy-proven rejection decreased at 12 months (53% vs. 27.5%) with daclizumab, MMF, steroids, and cyclosporine, but graft loss due to rejection was 2%.

• Ciancio et al. conducted a randomized 3-arm trial comparing Thymoglobulin, Campath, and daclizumab induction.

• The study found that patients in the Campath group had lower tacrolimus trough levels, remained steroid-free 1 year postoperatively, and had no difference in infection rates or other adverse events.

• The transplant case presented a patient with a PRA of 25% (moderate immunological risk) and recommended anti-thymocyte globulin (rabbit) + methylprednisolone as the induction regimen.

• The case also recommended tacrolimus + mycophenolate + prednisone (taper to 5mg at day 28) as the maintenance regimen, as CNIs are the mainstay of maintenance immunosuppression.

• Steroids were minimized due to the patient's diabetes, which increases blood glucose levels.

• Overall, different induction and maintenance immunosuppression strategies can be used to achieve lower rates of acute rejection and graft loss, with careful consideration of individual patient factors and risk profiles.
