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.

Hepatic Encephalopathy01:29

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates...

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...
