Abstract:
Posterior reversible encephalopathy syndrome features reversible cortical neurologic dysfunction and characteristic findings on brain imaging studies. This syndrome can be caused by several agents including traditional chemotherapy and immunosuppressive drugs. Targeted therapies such as agents binding vascular endothelial growth factor/VEGFR, CD20 and cytotoxic T-cell lymphocyte antigen 4 (CTLA-4) antigens are also among the culprits. Vemurafenib is a BRAF gene inhibitor that has not been previously linked with posterior reversible encephalopathy syndrome. We report herein the first such case and believe that further studies confirming this association are warranted. We further review the existing posterior reversible encephalopathy syndrome cases associated with targeted therapies in the scientific literature.
Insights
Posterior reversible encephalopathy syndrome (PRES) can be caused by targeted therapies. This report details the first case of PRES associated with vemurafenib, a BRAF inhibitor, highlighting a new potential cause for this neurological condition.
Area of Science:
- Neurology
- Oncology
- Pharmacology
Background:
- Posterior reversible encephalopathy syndrome (PRES) is a neurological condition characterized by reversible cortical dysfunction and specific brain imaging findings.
- PRES is associated with various agents, including chemotherapy, immunosuppressants, and targeted therapies like anti-VEGFR, anti-CD20, and anti-CTLA-4 agents.
Purpose of the Study:
- To report the first case of Posterior Reversible Encephalopathy Syndrome (PRES) associated with vemurafenib, a BRAF gene inhibitor.
- To review existing literature on PRES cases linked to targeted therapies.
Main Methods:
- Case report of a patient developing PRES.
- Literature review of targeted therapy-associated PRES.
Main Results:
- The study presents the first documented case of vemurafenib-induced Posterior Reversible Encephalopathy Syndrome (PRES).
- The review of scientific literature provides context on other targeted therapies implicated in PRES.
Conclusions:
- Vemurafenib, a BRAF inhibitor, is identified as a potential cause of Posterior Reversible Encephalopathy Syndrome (PRES).
- Further research is warranted to confirm the association between vemurafenib and PRES.
- This finding expands the spectrum of targeted therapies linked to PRES.
