Abstract
Background: Myasthenic crisis (MC) is a rare but potentially fatal complication that can significantly worsen the prognosis of patients with myasthenia gravis (MG). However, predicting the occurrence of MC remains challenging. Therefore, this study aimed to identify potential risk factors associated with MC.
Methods: A retrospective study was conducted using the MG Cohort Database at the West China Hospital of Sichuan University from January 2004 to August 2023. The multivariate Cox regression analysis was performed to determine the risk factors for MC.
Results: Among the 1150 patients with MG included in the final analysis, 128 (11.1%) experienced at least one episode of MC. Independent risk factors identified for MC included age (hazard ratio [HR]: 1.02, 95% confidence interval [CI]: 1.01–1.03, p < 0.001), quantitative MG (QMG) score (HR: 1.04, 95% CI: 1.01–1.07, p = 0.003), MG Foundation of America (MGFA) class at diagnosis (HR: 3.19, 95% CI: 2.38–4.28, p < 0.001), and the presence of thymoma (HR: 3.21, 95% CI: 2.13–4.85, p < 0.001). In contrast, generalized MG (p = 0.891) and the presence of antimuscle-specific tyrosine kinase (MuSK) antibodies (p = 0.107) did not significantly increase the risk of developing MC.
Conclusion: Age, disease severity as indicated by the QMG score and MGFA class at diagnosis, along with thymoma presence were identified as potential predictors for MC in patients diagnosed with MG.
