Longitudinal MuSK antibody levels may correlate with disease severity in MuSK myasthenia gravis

Key Points

• MuSK antibody levels correlate with disease severity in patients with myasthenia gravis, indicating their potential as a biomarker.
• Significant differences were observed between MuSK antibody levels and total IgG, establishing their importance in monitoring disease activity.
• Analysis focused on intrapatient variations, emphasizing the need for individual assessments over generalized findings.
• Findings support the use of serial biomarker monitoring, suggesting it could enhance therapeutic strategies for managing myasthenia gravis.
