Post-thymectomy myasthenia gravis is linked to antiacetylcholinesterase receptor antibodies

Takeaway

  • Antiacetylcholinesterase receptor (antiAChR) antibody-positivity is associated with post-thymectomy onset myasthenia gravis (PostTx MG); late-onset PostTx MG is linked to thymic tumor relapse.

Why this matters

  • Pre-operative serum antiAChR antibody titers and electrophysiologic tests should be performed in people with thymic tumors.
