Myasthenia Gravis and Physical Exercise: A Novel Paradigm
The benefits of physical exercise for healthy individuals are well-established, particularly in relation to reducing the risks of chronic lifestyle related diseases. Furthermore, physical exercise has been seen to provide beneficial effects in many chronic diseases such as multiple sclerosis, rheumatoid arthritis, and chronic obstructive pulmonary disease and is therefore recommended as part of the treatment regimen. Myasthenia Gravis (MG) is a chronic autoimmune disease that causes neuromuscular transmission failure resulting in abnormal fatigable skeletal muscle weakness. In spite of this fluctuating skeletal muscle weak...

Single-cell approaches to investigate B cells and antibodies in autoimmune neurological disorders.
Abstract Autoimmune neurological disorders, including neuromyelitis optica spectrum disorder, anti-N-methyl-D-aspartate receptor encephalitis, anti-MOG antibody-associated disorders, and myasthenia gravis, are clearly defined by the presence of autoantibodies against neurological antigens. Although these autoantibodies have been heavily studied for their biological activities, given the heterogeneity of polyclonal patient samples, the characteristics of a single antibody cannot be definitively assigned. This review details the findings of polyclonal serum and CSF studies and then explores the advances made by sing...

CONCLUSIONS: Our patients were extensive and widespread exposed to drugs during the follow-up period but we did not find and association with severe exacerbation episodes. Just over half of the patients had at least one exacerbation episode during the study period, most of them were mild. Further studies with larger sample sizes are necessary to corroborate these conclusions and to study possible correlations between the use of drugs and the risk of exacerbation episodes.

Early and long-term effect of the treatment with pyridostigmine in patients with gmppb-related cms
Congenital myasthenic syndromes (CMS) consist of a heterogeneous group of disorders due to mutations in genes involved in the signal transmission of the neuromuscular junction [1,2]. Different genes encoding proteins involved in glycosylation have been identified causing CMSs [3,4]. GMPPB is one of them, since it encodes the enzyme GDP-mannose pyrophosphorylase B that catalyses the conversion of mannose-1-phosphate and GTP to GDP-mannose [4], essential for the glycosylation of key proteins involved in the neuromuscular junction development and function.

Management of Juvenile Myasthenia Gravis
Juvenile Myasthenia Gravis (JMG) is a rare disorder, defined as myasthenia gravis in children younger than 18 years of age. While clinical phenotypes are similar to adults, there are a number of caveats that influence management: broader differential diagnoses; higher rates of spontaneous remission; and the need to initiate appropriate treatment early, to avoid the long-term physical and psychosocial morbidity. Current practice is taken from treatment guidelines for adult MG or individual experience, with considerable variability seen across centers. We discuss our approach to treating JMG, in a large specialist JMG servic...

Slow-binding inhibitors of acetylcholinesterase of medical interest.
Abstract Certain ligands slowly bind to acetylcholinesterase. As a result, there is a slow establishment of enzyme-inhibitor equilibrium characterized by a slow onset of inhibition prior reaching steady state. Three mechanisms account for slow-binding inhibition: a) slow binding rate constant kon, b) slow ligand induced-fit following a fast binding step, c) slow conformational selection of an enzyme form. The slow equilibrium may be followed by a chemical step. This later that can be irreversible has been observed with certain alkylating agents and substrate transition state analogs. Slow-binding inhibitors presen...

A New and Easily Used Modified Myasthenia Gravis Score
Myasthenia gravis (MG) is a common postsynaptic neuromuscular junction disease in which fluctuating muscular fatigability is the clinical hallmark. The muscles of the eyelids, limbs, pharynx, and respiration are commonly involved in sequence corresponding to the disease severity. The prevalence of MG ranged from 2 to7 per 10,000 persons, and it was more prevalent in females. [1] Since MG is a chronic neuromuscular weakness with fluctuating severity, a validated and reliable tool to quantify the severity of muscle weakness at different timing during a patient's course of illness is required.

A Practical Approach to Managing Patients With Myasthenia Gravis —Opinions and a Review of the Literature
When the diagnosis of myasthenia gravis (MG) has been secured, the aim of management should be prompt symptom control and the induction of remission or minimal manifestations. Symptom control, with acetylcholinesterase inhibitors such as pyridostigmine, is commonly employed. This may be sufficient in mild disease. There is no single universally accepted treatment regimen. Corticosteroids are the mainstay of immunosuppressive treatment in patients with more than mild MG to induce remission. Immunosuppressive therapies, such as azathioprine are prescribed in addition to but sometimes instead of corticosteroids when backgroun...

Myasthenia gravis (MG) is the prototypical autoimmune disorder caused by specific autoantibodies at the neuromuscular junction. Broad-based immunotherapies, such as corticosteroids, azathioprine, mycophenolate, tacrolimus, and cyclosporine, have been effective in controlling symptoms of myasthenia. While being effective in a majority of MG patients many of these immunosuppressive agents are associated with long-term side effects, often intolerable for patients, and take several months to be effective. With advances in translational research and drug development capabilities, more directed therapeutic agents that can alter ...
