Kidney Transplantation A Rare Case Report and Clinical Insights

Introduction
Primary central nervous system (PCNS) post-transplant lymphoproliferative disease (PTLD) is a rare but severe complication of solid organ transplantation. It presents unique diagnostic and therapeutic challenges, with high mortality rates. This case report discusses a 54-year-old male who developed PCNS-PTLD following a kidney transplant.

Case Summary

• The patient underwent a renal transplant 22 years prior for end-stage renal disease.
• He had been on long-term immunosuppressive treatment (prednisolone and mycophenolate mofetil).
• In January 2019, he presented with aphasia and partial seizures.
• Brain MRI showed an expansive cortical mass in the left temporal lobe.
• Biopsy confirmed diffuse large B-cell lymphoma (DLBL).
• Due to his renal allograft, Methotrexate was unsuitable.
• He was treated with Cytarabine, but developed febrile neutropenia leading to sepsis and died on day 15.

Clinical Significance and Broader Implications
PTLD is a well-documented complication in solid organ transplantation. The American Society of Transplantation highlights that post-transplant malignancies, including PTLD, are among the most serious challenges faced by transplant recipients.

Challenges in Treatment and Management

• PCNS-PTLD is difficult to treat due to the blood-brain barrier limiting drug penetration.
• Standard PTLD treatments, including Rituximab, are less effective in PCNS cases.
• High-dose Methotrexate and Cytarabine-based regimens are considered effective but pose risks for renal transplant patients.

Future Directions and Research Needs
Further clinical studies are needed to optimize diagnostic and therapeutic strategies for PCNS-PTLD. Immunosuppression management and the role of targeted therapies require further exploration to improve patient outcomes.
