Active clinical trials for "Lambert-Eaton Myasthenic Syndrome"

A few recent observational studies show that despite the lack of clear recommendations, many individuals with myasthenia participate in exercise. However, no link has been found between exercise and the severity of myasthenia symptoms, measured by the Muscle Myasthenia Score or the Myasthenia Gravis Composite Score. This suggests that there are other factors that may limit or prevent some individuals from being active, or factors which may facilitate participation in exercise. Studies in other diseases have shown that there are internal (beliefs, motivation, etc.) and external (cost, accessibility, etc.) factors unrelated to the disease which may play a role in exercise participation. The aim of this study is to identify factors that facilitate or limit exercise in individuals with autoimmune myasthenia gravis, congenital myasthenia syndrome and Lambert-Eaton syndrome.

The purpose of this study is to determine the effectiveness and adverse effects of 3,4-diaminopyridine for the treatment of the Lambert-Eaton Myasthenic Syndrome (LEMS) and Congenital Myasthenic Syndromes (CMS).

This protocol has provided 3,4 diaminopyridine (DAP) under a treatment-use IND to patients with congenital myasthenic syndrome (CMS). It is currently closed to enrollment.

Lambert-Eaton Myasthenic Syndrome (LEMS) is a rare autoimmune disorder which affects the nerve-muscle junction. The major symptoms of LEMS are progressive muscle weakness. Many patients experience other symptoms like dry mouth or impotence. Congenital Myasthenia (CM) is an inherited disorder with similar affects and symptoms. 3,4-Diaminopyridine (DAP) is an experimental drug that has improved strength in some subjects with (LEMS). There are no other accepted treatments for LEMS and DAP has relatively few side effects.

Our aim is to establish multi-center national Egyptian database of information for inherited and acquired neuromuscular diseases in infants and children from 0 to 18 years of age.
