[Immunologic pathology in patients with disorders of neuromuscular transmission].

The article presents an analysis of long-term follow up studies of more than 2500 patients with various forms of neuromuscular transmission impairments. The results of repeated observations, employing electromyographic and immunologic techniques made it possible to raise a question about the homogeneity and differences in the mechanisms of myasthenia formation, and also about combinations of myasthenia with other autoimmune diseases and with the myasthenic syndrome of Lambert- Iton 's type.
