The study, "Nocebo effect in myasthenia gravis: systematic review and meta-analysis of placebo-controlled clinical trials", published in the journal Acta Neurologia Belgica, is a meta-analysis of adverse events experienced by patients with myasthenia gravis following placebo treatment. The study demonstrates a low nocebo dropout rate in MG comapted to central nervous system disorders.
While many MG patients were affected by fatigue, sleepiness, depression and anxiety, the study, "Impact of autoimmune comorbidity on fatigue, slepiness and mood in myasthenia gravis", does not suggest that coexisting autoimmune diseases substantially contribute to the magnitude of these cumbersome comorbid symptoms. However, the higher frequency of steroid treatment may have counterbalanced the effects of the autoimmune comorbidity.
Results of the Phase 2 study were presented at the 2019 American Academy of Neurology Annual Meeting in May:
A group of scientists in Austria conducted a study to determine the efficacy of rituximab in treating myasthenia gravis. The study, titled, “High efficacy of rituximab for myasthenia gravis: a comprehensive nationwide study in Austria” looked at 56 patients and studied their response to rituximab, finding that 26.4% of the patients studied were in remission after three months of treatment. In this retrospective study on RTX for MG, the largest to date, RTX appeared safe, efficacious and fast acting. Benefit from RTX was greatest in MuSK ab + MG.
