This study provides Class IV evidence that for patients with anti-MuSK MG, rituximab increased the probability of a favorable outcome.
Introduction: A randomized trial demonstrated benefit from thymectomy in nonthymomatous acetylcholine receptor (AChR)‐antibody positive myasthenia gravis (MG). Uncontrolled observational and histologic studies suggest thymectomy may not be efficacious in anti–muscle‐specific kinase (MuSK)‐MG. Methods: The therapeutic impact of thymectomy was evaluated from data collected for a multicenter, retrospective blinded review of rituximab in MuSK‐MG. Results: Baseline characteristics were similar between thymectomy (n = 26) and nonthymectomy (n = 29) groups, including treatment with rituximab (42% vs. 45%). At last visit, 35% of thymectomy subjects reached the primary endpoint, a Myasthenia Gravis Foundation of America (MGFA) post‐intervention status (PIS) score of minimal manifestations (MM) or better, compared with 55% of controls (P = 0.17). After controlling for age at onset of MG, rituximab, prednisone, and intravenous immunoglobulin/plasma exchange treatment, thymectomy was not associated with greater likelihood of favorable clinical outcome (odds ratio = 0.43, 95% confidence interval 0.12–1.53, P = 0.19). Discussion: Thymectomy was not associated with additional clinical improvement in this multicenter cohort of MuSK‐MG patients. Muscle Nerve 59:404–410, 2019
In nearly every US state, a large mismatch exists between the need for neurologists and neurologic services and the availability of neurologists to provide these services. Patients with neurologic disorders are rising in prevalence and require access to high-level care to reduce disability. The current neurology mismatch reduces access to care, worsens patient outcomes, and erodes career satisfaction and quality of life for neurologists as they face increasingly insurmountable demands. As a community, we must address this mismatch in the demand and supply of neurologic care in an aggressive and sustained manner to ensure the future health of our patients and our specialty. The American Academy of Neurology has multiple ongoing initiatives to help reduce and resolve the existing mismatch. With the intent of raising awareness and widening the debate nationally, we present a strategic plan that the Academy could implement to coordinate and expand existing efforts. We characterize the suggested strategies as shaping the demand, enhancing the workforce, and advocating for neurologist value. The proposed framework is based on available data and expert opinion when data were lacking. Prioritization of strategies will vary by geography, practice setting, and local resources. The time to act is now to allow concerted effort and targeted interventions to avert this looming public health crisis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
