Neurologic complications after solid organ transplantation

Area of Science:

• Neurosurgery
• Immunology
• Transplant Medicine

Background:

• Neurologic complications are frequent and serious after solid organ transplantation, affecting 10-59% of recipients.
• These complications are categorized as common to all transplants or specific to the transplanted organ.

Purpose of the Study:

• To review the spectrum of neurologic complications following solid organ transplantation.
• To highlight the common causes, organ-specific issues, and diagnostic challenges.

Main Methods:

• Literature review of neurologic complications in solid organ transplant recipients.
• Analysis of incidence, types, and risk factors of these complications.

Main Results:

• Neurotoxicity from immunosuppressive drugs, particularly calcineurin inhibitors, is the most common complication.
• Other frequent issues include seizures, central nervous system infections, encephalopathy, and neoplasms.
• Liver transplant recipients have a higher incidence of neurologic issues (13-47%), with encephalopathy being most common.
• Stroke is prevalent in kidney transplant patients, while cerebral infarction and bleeding occur more after heart transplants.

Conclusions:

• Neurologic complications significantly impact transplant recipient morbidity.
• Identifying specific causes and achieving early diagnosis are hindered by patient status and co-existing disorders.
• Further research is needed to improve the management and outcomes of these neurologic complications.
