  • Title: Correlation between acetylcholine receptor antibody levels and thymic pathology in myasthenia gravis: a review.
    Author: Huang GZ, Lo YL.
    Journal: J Clin Neuromuscul Dis; 2013 Jun; 14(4):209-17. PubMed ID: 23703018.
    Abstract:
    Myasthenia gravis is the most common chronic autoimmune neuromuscular disease. Anti-acetylcholine receptor (AChR) antibodies are found in at least 80% of patients with generalized myasthenia and have been implicated in disease pathogenesis. Thymic abnormalities are frequently found in seropositive patients, and the thymus is thought to be involved in generation of autoimmunity. This article reviews existing literature on the role of AChR antibodies in the pathogenesis of myasthenia gravis, and the correlation between AChR antibody titers and thymic pathology. Most studies found that highest titers are seen in thymic hyperplasia, followed by intermediate titers in thymoma, and lowest titers in atrophic or normal thymus. One publication found no difference between titers in thymoma and normal thymus.
