Abstract
Several neurological presentations have been reported following coronavirus 2019 (COVID-19) infection. This case report describes three myasthenia gravis (MG) patients presented following COVID-19 infection. We report three adult patients with myasthenic Gravis and COVID-19 infection. The patients are between 38 and 61 years old. Case 1 is a 61-year-old woman with progressive dysphagia, nasal speech, ocular ptosis, diplopia, and proximal muscle weakness for 10 days. She had a COVID-19 infection 6 weeks ago. Case 2 is a 57-year-old man with clinical symptoms of muscular fatigability, diplopia, ptosis, and dysphagia for a week and a positive COVID-19 infection 10 days ago. Case 3 is a 38-year-old woman with fatigability, ptosis, dysphagia, and a diagnosis of COVID-19 infection 4 weeks ago. All patients had a positive RT-PCR for COVID-19 infection by nasopharyngeal swab test and a high-level acetylcholine receptor antibody in the serum. All patients were treated with pyridostigmine and prednisolone with a favorable outcome. MG may appear following COVID-19 infection, and the role of molecular mimicry and latent MG activation should be considered the cause of the disease onset.
