From the Guidelines
Treatment for kidney transplant rejection should prioritize the use of immunosuppressive medications, with a focus on minimizing morbidity, mortality, and improving quality of life, as evidenced by the most recent and highest quality study available 1.
Key Considerations
- The standard approach to preventing kidney transplant rejection includes a combination of medications such as tacrolimus or cyclosporine (calcineurin inhibitors), mycophenolate mofetil, and corticosteroids like prednisone.
- For acute rejection episodes, high-dose intravenous methylprednisolone (500-1000mg daily for 3-5 days) is often the first-line treatment, as supported by earlier guidelines 1.
- In cases of steroid-resistant rejection, alternative treatments such as anti-thymocyte globulin (ATG) or rituximab may be considered.
- Regular blood tests are crucial to monitor medication levels and kidney function, with the frequency of testing adjusted based on the patient's stability and response to treatment.
- Medication dosages should be individualized based on blood levels, kidney function, and side effects to minimize the risk of adverse events.
Management of Immune-Related Adverse Events
- The management of immune-related adverse events, including renal toxicities, is critical in patients treated with immune checkpoint inhibitor therapy, as highlighted in the most recent guideline update 1.
- Patients should be closely monitored for signs of renal toxicity, including urinary frequency, dark cloudy urine, fluid retention, and abdominal or pelvic pain.
- Renal biopsy is typically not necessary unless the acute kidney injury (AKI) is refractory to steroids and other immunosuppressant agents.
Prioritizing Patient Outcomes
- The primary goal of treatment for kidney transplant rejection is to minimize morbidity, mortality, and improve quality of life, as emphasized in the guideline recommendations 1.
- Treatment decisions should be made in consultation with a multidisciplinary team, taking into account the individual patient's needs, medical history, and response to treatment.

- Corticosteroids 2
From the Research
Kidney Transplant Rejection Treatment
- The treatment of acute rejection in kidney transplant recipients typically involves the use of high-dose steroids, such as methylprednisolone, and optimization of basal immunosuppression 3.
- In cases of steroid-resistant rejection, rabbit antithymocytic polyclonal globulins may be used as rescue therapy 3.
- For acute antibody-mediated rejection, the current standard-of-care therapy is the combination of plasma exchange with intravenous immunoglobulin (IVIG) 3.
- New drugs such as Rituximab, Bortezomib, Eculizumab, and C1 inhibitors are being studied for their potential role in treating acute rejection 3.
Response to Treatment
- The response to pulse methylprednisolone therapy in renal transplant recipients with acute allograft rejection can be evaluated after at least 3 days have passed since completion of therapy 4.
- The time course of change in serum creatinine levels can be used to determine the response to treatment, with significant differences between responders and nonresponders seen at day 5 4.
Pharmacokinetics and Rejection
- Individual variability in pharmacokinetic parameters of steroids, such as methylprednisolone, may contribute to the risk of rejection episodes in kidney transplant patients 5.
- Patients with a shorter elimination half-life of steroids may be at higher risk of rejection, and a twice-daily dose fraction may be useful in low-dose steroid regimens 5.
Immunosuppression Regimens
- Steroid-avoidance immunosuppression regimens, such as those using tacrolimus and mycophenolate mofetil, can be effective in reducing the risk of acute rejection in kidney transplant recipients 6.
- The use of antithymocyte globulins or monoclonal anti-CD3 antibodies, such as muromonab CD3 (OKT3), may be indicated in selected cases of corticosteroid-resistant acute rejection 7.
