Myasthenia gravis patients with anti-MuSK antibodies.
In myasthenia gravis (MG) patients without detectable anti-acetylcholine receptor (anti-AChR) antibody, referred to as seronegative myasthenia gravis patients, there is a variable proportion of patients with antibodies against the muscle-specific kinase (MuSK). MuSK antibodies were found in 8 (29.6%) of our 27 patients with generalized MG without anti-AChR antibodies. All these patients were fe...

Myasthenia gravis (MG) is an autoimmune disorder with easy fatigability of the muscles based on a neuromuscular transmission defect. Most myasthenic patients have antiacetylcholine receptor antibodies which attach to the acetycholine receptor of the postsynaptic membrane of the skeletal muscles and decrease the amplitude of miniature endplate potentials (mepp) and endplate potentials (epp) caus...
متن کاملAnti-MuSK myasthenia gravis presenting with purely ocular findings.
BACKGROUND Antibodies to a muscle-specific receptor tyrosine kinase (MuSK) have been found in approximately 40% of patients with generalized myasthenia gravis who are seronegative for the antiacetylcholine receptor antibody. Many of the patients with anti-MuSK antibodies have prominent oculobulbar symptoms or weakness of the neck and respiratory muscles, but patients with ocular myasthenia have...
متن کاملIncreased complement consumption in MuSK-antibody-positive myasthenia gravis patients.
OBJECTIVE To investigate the activation of different complement pathways in myasthenia gravis (MG) subtypes. SUBJECTS AND METHODS Levels of complement breakdown products for different complement pathways were measured using ELISA in sera of acetylcholine receptor antibody (AChR-Ab)-positive (n = 21), muscle-specific receptor tyrosine kinase (MuSK)-Ab-positive (n = 23) and seronegative general...
متن کاملRepetitive Nerve Stimulation in MuSK-Antibody-Positive Myasthenia Gravis
BACKGROUND AND PURPOSE Responses to repetitive nerve stimulation (RNS) in patients with muscle-specific tyrosine kinase (MuSK) antibody (Ab)-positive myasthenia gravis (MG) vary depending on the muscles tested. We analyzed the RNS responses of limb and facial muscles in MuSK-Ab-positive and acetylcholine receptor (AChR)-Ab-negative MG (MuSK MG) and MuSK-Ab-negative and AChR-Ab-negative [double-...
