Abstract

Insights

Immune checkpoint inhibitor (ICI) drugs can cause neuromuscular junction dysfunctions. Analysis of adverse event reports revealed a significant association between ICI use and these serious conditions, with over 30% resulting in death.

Area of Science:

  • Pharmacovigilance
  • Neurology
  • Oncology

Background:

  • Immune checkpoint inhibitors (ICIs) are crucial cancer therapies.
  • Adverse effects of ICIs on neuromuscular junctions are not fully understood.
  • Neuromuscular junction dysfunctions can significantly impact patient health.

Purpose of the Study:

  • To assess neuromuscular junction dysfunctions in cancer patients receiving ICI therapy.
  • To analyze adverse events reported in the Food and Drug Administration Adverse Event Reporting System (FAERS) database.
  • To quantify the association between ICI use and neuromuscular junction dysfunctions.

Main Methods:

  • Utilized FAERS data from January 2004 to December 2020.
  • Employed disproportionate and Bayesian analysis to assess ICI-neuromuscular junction dysfunction association.
  • Compared onset time and outcomes across different ICI regimens.

Main Results:

  • Identified 557 reports of neuromuscular junction dysfunctions (0.63%) out of 88,617 adverse events.
  • Confirmed positive associations between multiple ICIs (ipilimumab, nivolumab, pembrolizumab, etc.) and neuromuscular junction dysfunctions.
  • Nivolumab and pembrolizumab showed similar rates of neuromuscular junction dysfunctions, with no significant difference in onset time.

Conclusions:

  • Over 30% of reported neuromuscular junction dysfunctions linked to ICIs resulted in patient death.
  • Highlights the critical need for ongoing monitoring and risk evaluation of ICI-induced neuromuscular toxicity.
  • Recommends further comparative studies to better understand ICI-specific risks.

Myasthenia Gravis: Overview and Treatment

Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Myasthenia Gravis: Diagnostic Tests

Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...

Neuromuscular Junction And Blockade

The site of chemical communication between a motor neuron and a muscle fiber is called the neuromuscular junction (NMJ). The end of the motor neuron at the NMJ divides into a cluster of synaptic end bulbs. The cytoplasm of these bulbs consists of synaptic vesicles enclosing acetylcholine molecules, the principal neurotransmitter released at the NMJ. The region opposite the synaptic bulb that ends in the muscle fiber is called the motor end plate, which has acetylcholine receptors. Within the...
