Striational (Striated Muscle) Antibodies, Serum
Clinical Information: Autoantibodies directed against the contractile elements of striated muscle are
found in 30% of adult patients with myasthenia gravis and in 80% of those with thymoma. These
antibodies may also be detected in patients with: Lambert-Eaton myasthenic syndrome, small-cell lung
carcinoma, breast carcinoma, patients treated with D-penicillamine, bone marrow transplant recipients
having graft-versus-host disease, and autoimmune liver disorders.
Useful For: This test is a useful serological aid in the diagnosis of thymoma, especially in patients with
onset of myasthenia gravis (MG) younger than 45 years. It is more predictive of thymoma when
accompanied by a muscle acetylcholine receptor (AChR) modulating antibody value of > or =90% AChR
loss and is most predictive of thymoma when accompanied by CRMP-5-IgG. It is useful as a screening
test for MG in older patients, especially when tests for muscle AChR antibodies are negative. Serial
measurements are useful in monitoring the efficacy of immunosuppressant treatment in patients with MG.
Serial measurements are useful after treatment of thymoma. Measurements of muscle AChR binding,
muscle AChR modulating antibody, and CRMP-5-IgG (if initially positive) are also recommended. Serial
measurements in recipients of D-penicillamine or bone marrow allografts may be useful in monitoring
autoimmune complications and graft-versus-host disease, respectively.
Interpretation: Autoantibodies reactive with contractile elements of skeletal muscle are detectable in
