The rare disease leads to weakening of the muscles


Infection with Covid-19 can cause the miastenia grave, a rare autoimmune disease that causes neurological complications. This was revealed by a team of experts following some studies. Symptoms, found in several molecular swab positive patients, are muscle weakness, diplopia (double image perception), dysphagia (difficulty in swallowing) and hypophonia (weakening of the voice).

What is myasthenia gravis

It’s about a autoimmune pathology rather rare in which the organism creates antibodies that go to hit the neuromuscular junction, the point of contact where the electrical signals of neurons are transmitted to the muscle fibers. The result is a defect in nerve transmission, resulting in weakness in one or more muscle groups“. He explained it Domenico Restivo, professor of the Department of Medicine of the Garibaldi Hospital in Catania, who coordinated the study on the correlation between miastenia grave e Coronavirus.

The study was carried out on three patients elderly people tested positive for the swab. In addition to high fever for several days, everyone showed up muscle fatigue e diplopia; one of them too dysphagia; another one too bilateral ocular ptosis e ipofonia.

What is the correlation with Covid

That some infections can trigger autoimmune neurological diseases is a known phenomenon. We now know that the SARS-CoV-2 virus is also capable of causing this effect“, has explained Diego Centonze, co-author of the study.

The Coronavirus, according to experts, it can trigger myasthenia gravis in two ways. The first is the antibody production which attack the receptors of neuromuscular junctions, which in some parts are similar to the pathogen. The second is a ‘alteration of the immune system.
