Abstract |
We describe the clinical course of patients with juvenile myasthenia gravis who experienced spontaneous remission and review the literature. This is a retrospective study of 13 patients with spontaneous remission from a cohort of 133 patients younger than 18-years-old. We compared several variables with potential prognostic value in patients with and without spontaneous remission. Ten percent of patients (13/133) experienced spontaneous remission. There was no difference in age at onset or sex compared to the overall JMG population. Spontaneous remission occurred in 2/40 (5.0%; 95% CI: 0.6-16.9) patients in Class I (ocular); in 11/53 (20.8%; 95% CI: 10.8-34.1) patients in Class II-III (mild, moderate, generalized) (p < 0.0018) and in 0/40 patients in Class IV-V (severe, needs intubation). Of the AChR antibody positive patients, 10/97 (10.3%; 95% CI: 5.0-18.1) had spontaneous remission, compared with 2/29 (6.9%; 95% CI: 0.9-22.8) of those without AChR antibodies (p = 0.583). Strikingly, none of the 36 patients with thyroid antibodies had spontaneous remission compared with 13/58 (22.4%) of those without thyroid antibodies (95% CI: 7.3-21.8; p < 0.001). Ten percent of patients with juvenile myasthenia gravis achieved spontaneous remission, mainly in those with Class II-III disease and no associated thyroid antibodies.
