Takotsubo Syndrome and myasthenia gravis: When neuromuscolar disease meets cardiac dysfunction
Myasthenia gravis (MG) is a neuromuscular autoimmune disease that affects the skeletal muscle through the production of autoantibodies against the nicotinic acetylcholine receptor at the neuromuscular junction, thus causing defective neuromuscular transmission in skeletal muscles . MG occurs in 1: 7500 individuals, affecting women during the second to third decade and men in their fifth and sixth decade of life . Typically, patients experience muscle weakness and fatigue, as well as fluctuating and fatigable extraocular (e.g.
Conclusions: One or more types of ADs developed in AE patients, and patients with anti-LGI1 encephalitis had a higher frequency of autoimmune comorbidities than those with anti-NMDAR encephalitis. And we found that autoimmune comorbidities did not affect the clinical course of AE.
Myasthenia gravis (MG) is an autoimmune diseases characterized by fatigue and weakness of skeletal muscles. B-lymphocyte-activating factor (BAFF), an essential factor for B cell differentiation and development, i...
Abstract Introduction: Lambert-Eaton myasthenic syndrome is an autoimmune disease of the neuromuscular junction characterized by a presynaptic defect of neuromuscular transmission resulting in muscle weakness and fatigability. Diagnostic features are specific neurophysiological alterations and autoantibody detection. The present review is focused on the use of Amifampridine Phosphate to treat LEMS patients. Areas covered: Medline search from 1990 to 2019 was examined using the free subject terms: Lambert-Eaton myasthenic syndrome, LEMS, Amifampridine, 3,4-diaminopyridine, which were then combined with Treatment, T...
To improve the clinical diagnosis of neural autoimmune diseases, we developed an in-house muscle-specific kinase (MuSK) antibody cell-based assay (CBA) and compared its performance with RIA, ELISA, and other CBAs. Sera from patients with myasthenia gravis (MG) and other autoimmune diseases were analyzed. We found 46 (18.3%) MuSK-CBA Ab positive cases among 251 AChR-Ab negative cases [patients] and 4 (0.6%) MuSK-CBA Ab positive cases [among] the 624 AChR-Ab positive samples. Comparing these with available clinic assays, our highly specific CBA method is more sensitive than commercial ELISA and IFA(indirect immunofluorescence assay).
Myasthenia Gravis (MG) – an autoimmune neuromuscular disease – is known by the production of autoantibodies against components of the neuromuscular junction mainly to the acetylcholine receptor, which cause the destruction and compromises the synaptic transmission. This disease is characterized by fluctuating and fati gable muscle weakness, becoming more intensive with activity, but with an improvement under resting. There are many therapeutic strategies used to alleviate MG symptoms, either by improving the transmission of the nerve impulse or by ameliorating autoimmune reactions with e.g.
AbstractAryl hydrocarbon receptor (AhR), a type of transcriptional factor, is widely expressed in immune cells. The activation of AhR signaling pathway depends on its ligands, which exist in environment and can also be produced by metabolism. Normal expressions of AhR and AhR-mediated signaling may be essential for immune responses, and effects of AhR signaling on the development and function of innate and adaptive immune cells have also been revealed in previous studies. Recent studies also indicate that aberrant AhR signaling may be related to autoimmune diseases, including rheumatoid arthritis (RA), systemic lupus eryth...
Thymic tumors are rare diseases with an incidence of 0.15 cases per 100,000 person-years. They can be associated with a variety of other syndromes, such as Myasthenia Gravis or autoimmune disorders. Among them, pure red cell aplasia is a hemato-pathological condition characterized by anemia, reticulocytopenia and erythroid cell hypoplasia of bone marrow. Here, we reported a case of a 62-year-old female with a long history of neurologic symptoms due to Myasthenia Gravis. She was diagnosed with thymoma, with mediastinal mass and pleural thickening.
