In a retrospective case note study of 86 patients with myasthenia gravis, 60 had an anti-acetylcholine receptor antibody assay performed by the regional immunology laboratory. Antibody was detected in 38% which compares with 66-93% in other series. Whilst the use of staphylococcal protein A to precipitate the antibody-receptor complex, rather than anti-human immunoglobulin, may be partly responsible for this low sensitivity, other methodological problems are likely to exist. It is suggested that this potentially critical assay becomes a subject for regular audit.

Background: Thymoma-associated myasthenia gravis (TAMG) is a subtype of myasthenia gravis (MG) that is associated with more severe symptoms and a relatively poor prognosis. Eculizumab, an inhibitor to target human C5 component of the complement cascade, is considered a treatment option for refractory generalized MG (gMG).
Objectives: To explore the safety and efficacy of eculizumab in patients with TAMG.

: Several significant associations between certain Human Leukocyte Antigen (HLA) alleles and myasthenia gravis (MG) subtypes were established in populations from Western Europe and North America and, to a lesser extent, from China and Japan. However, such data are scarcely available for Eastern Europe. This study aimed to analyze the associations of HLA Class I and II alleles with MG and its serological subtypes (with anti-acetylcholine receptor autoantibodies, RAch+MG, and double-seronegative, dSNMG) in myasthenic patients of Romanian descent.

Objective: To present cases of ptosis in HIV-1 patients on long-term antiretroviral therapy (ART) and review the existing literature.
Methods: Five HIV-1-positive patients with slowly progressive bilateral ptosis underwent a comprehensive diagnostic evaluation, including imaging studies, neurophysiological testing, muscle biopsy, and genetic analysis. A literature review was conducted.
