The etiology of autoimmune diseases is multifactorial. In many of them the stimulation by a specific autoantigen is claimed to be responsible for the initiation of the disease. Alternatively, an autoimmune state may be induced by a pure dysregulation of the immune system. Such is the case in which severe systemic lupus erythematosus (SLE) is induced in young patients with myasthenia gravis following thymectomy. We have referred to this set of events as the 'kaleidoscope of autoimmunity'. Herewith, we would like to present another example of the kaleidoscope phenomenon, namely: the emergence of a full blown clinical presentation of the primary antiphospholipid syndrome (APS-recurrent thromboembolic phenomena, repeated fetal loss with high titers of anti-cardiolipid antibodies) in a 32 y old female with myasthenia gravis, two years following thymectomy. Thymectomy in myasthenic patients may be associated with the emergence of new autoimmune conditions such as SLE and APS, pointing to the importance of immune dysregulation in the induction of these autoimmune diseases.

As one of the largest organs of our human body, skeletal muscle has good research prospects in myasthenia gravis (MG), the symptoms of which include systemic skeletal muscle weakness. Skeletal muscle is composed of two types of muscle fibers. Different fiber subtypes can be converted into each other; however, the underlying mechanism is not yet clear.

Background: Myasthenia gravis (MG) is strongly associated with thymic tumors, but whether it is also associated with extrathymic cancers is debatable or whether MG can be considered a paraneoplastic disorder for extrathymic cancers.
Methods: This is a retrospective analysis of the MG cohort for 23 years' time (January 2000 to May 2023), extracting cancer rates with clinical, electrophysiological, and biochemical cancer associations and the effect of chronic medications.
Results: We identified 436 patients with MG and 3924 controls.

Background And Purpose: Observational studies have indicated a high occurrence of coexistence between myasthenia gravis (MG) and autoimmune thyroid disease (AITD) in clinical settings, but the causal relationship between the two conditions remains ambiguous. Therefore, this study endeavors to investigate the causal links between MG, along with its subgroups, and AITD through a Mendelian randomization (MR) approach.
Methods: Genetic instrumental variables associated with MG and AITD were selected from three major publicly available GWAS databases for MR analysis.

Purpose: Myasthenia-gravis and Guillain-Barre-syndrome are two of the most common causes of acute and reversible neuromuscular-respiratory-failure(ARNRF), both may worsen respiratory-failure and need for invasive-mechanical-ventilation(IMV) for long-periods due to muscle-weakness. However, approitive IMV-mode for ARNRF patients that better gas-exchange and weaning in ARNRF remain unclear.
Materials And Methods: Critically-ill-patiens with IMV due to ARNRF, who could meet the weaning-criterias (after intubation for more than 7-days; difficult-weaning), between 2013, and 2023 were included in the study.
