Summary
Cyclosporine can cause neurotoxicity, affecting all nervous system levels in 0.5-35% of patients. Most adverse neurologic events are reversible upon cyclosporine dose reduction or discontinuation.
Area of Science:
- Neuroscience
- Pharmacology
- Toxicology
Background:
- Cyclosporine is an immunosuppressant with known potential for neurotoxicity.
- Adverse neurologic events (ANEs) associated with cyclosporine require thorough investigation.
Purpose of the Study:
- To comprehensively review and analyze patient-specific data on cyclosporine-induced neurotoxicity.
- To evaluate the epidemiology, clinical features, mechanisms, and management of these ANEs.
Main Methods:
- Conducted a comprehensive literature search for case reports and studies with patient-specific data on cyclosporine neurotoxicity.
- Manually reviewed cited references to ensure relevance.
- Analyzed collected information on all aspects of cyclosporine neurotoxicity.
Main Results:
- Cyclosporine neurotoxicity occurs in an estimated 0.5-35% of patients.
- Risk factors include high cyclosporine levels, drug interactions, and metabolic issues.
- Events affect the entire neuraxis, presenting with diverse clinical and diagnostic findings (CSF, EEG, neuroimaging).
Conclusions:
- Cyclosporine neurotoxicity is a significant concern with varied presentations.
- Reversibility is common with dose modification, though rare cases resolve spontaneously.
- Understanding mechanisms and risk factors is crucial for clinical management.
