From the Guidelines
Management of late transplant rejection requires prompt intervention with a combination of immunosuppressive therapies, including high-dose corticosteroids, optimization of baseline immunosuppression, and consideration of T-cell depleting agents or plasmapheresis for steroid-resistant or antibody-mediated rejection. For acute cellular rejection occurring beyond three months post-transplant, high-dose corticosteroids are the first-line treatment, typically methylprednisolone 500-1000mg IV daily for 3 days, as seen in the treatment protocols from the University of Utah and Cedars-Sinai 1. Baseline immunosuppression should be optimized by increasing calcineurin inhibitor levels, with the Stanford protocol suggesting a target trough of 8-12 ng/mL for tacrolimus or 150-200 ng/mL for cyclosporine 1. Some key points to consider in the management of late transplant rejection include:
- The use of plasmapheresis, intravenous immunoglobulin (IVIG), and rituximab or bortezomib for antibody-mediated rejection, as outlined in the protocols from Cedars-Sinai, Cleveland Clinic, and Stanford 1
- The importance of monitoring graft function closely after treatment, with laboratory tests every 1-2 weeks initially
- The potential need for multi-modal therapy targeting different immune pathways to successfully reverse rejection and preserve graft function, as the underlying mechanism of late rejection often involves both cellular and humoral components with development of donor-specific antibodies 1. In terms of specific treatment strategies, the protocol from Cedars-Sinai suggests methylprednisolone 500 mg QD × 3, rATG, plasmapheresis for hemodynamic compromise, IVIg 2 g/kg on days 1 and 30, and rituximab 1g on days 7 and 21, with refractory patients receiving bortezomib 1.3 mg/m2 on days 1,4,7, and 10 1. Similarly, the Cleveland Clinic protocol involves methylprednisolone 1g IV QD × 3, plasmapheresis 4–5 times over a week, and consideration of IVIg, rituximab, and bortezomib for unresolved cases 1. Overall, the management of late transplant rejection requires a tailored approach based on the individual patient's needs and the specific characteristics of the rejection episode, with a focus on prompt and effective intervention to preserve graft function and minimize morbidity and mortality.

From the Research
Management of Late Transplant Rejection
- The management of late transplant rejection involves preventing rejection without increasing the risk of infection or other long-term complications 2.
- Modifications for older recipients include reduction in the dosage or avoidance of calcineurin inhibitors, with or without the introduction of a mammalian target of rapamycin inhibitor and discontinuing the use of corticosteroids 2.
- Treatment of an acute rejection episode should follow the same protocol as for younger recipients, but special attention is needed to ensure reduction in the total immunosuppressive load 2.
Immunosuppressive Regimens
- Tacrolimus has become the workhorse of transplant professionals for avoidance of solid organ transplant rejection due to its potent immunosuppressive qualities and straightforward dosing 3.
- Mycophenolate mofetil (MMF) has been shown to decrease rejection in simultaneous pancreas-kidney transplantation when combined with tacrolimus or cyclosporine 4.
- The use of generic immunosuppressants, such as Myfenax Teva and Tacrolimus Sandoz, has been found to be safe and effective in heart transplant patients 5.
Prevention and Treatment of Rejection
- Prevention and treatment of rejection are crucial in liver transplant recipients, with a focus on T-cell-mediated rejection, antibody-mediated rejection, and chronic rejection 6.
- Future directions of rejection management include biomarkers of rejection, which may allow for monitoring of patients who are considered high risk for rejection and detection of rejection before there is any clinical evidence 6.
- Immunosuppression minimization, withdrawal, and personalization are also being explored as new frontiers in rejection management 6.
