The Japanese clinical guidelines 2022 for myasthenia gravis and Lambert –Eaton myasthenic syndrome
AbstractThe revised Japanese clinical guidelines for myasthenia gravis (MG) and Lambert –Eaton myasthenic syndrome (LEMS) were published in 2022. The notable points in these guidelines (GLs) are as follows. 1) These are the first Japanese GLs to include a description of LEMS. 2) Diagnostic criteria of MG are revised to lessen the incidence of false-negative patients. 3) MG is divided into six clinical subtypes. 4) A high-dose oral steroid regimen with escalation and de-escalation schedule is not recommended by the GLs. 5) The GLs promote the early fast-acting treatment strategy initially proposed in the previous GLs. 6) ...

Epidemiological study of myasthenia gravis in Japan
AbstractMyasthenia gravis (MG) is an autoimmune-mediated neurological disorder. The relationship between MG and thymic abnormalities is well recognized, and thymectomy is one of the therapies for anti-acetylcholine receptor (AChR) antibody-positive MG. The major pathogenic factor is anti-AChR antibody followed by anti-muscle specific kinase (MuSK) antibody, and commercial kits are available to detect these antibodies. Several decades ago, the prognosis of MG was not favorable; therefore, the Ministry of Health and Welfare (predecessor of the Ministry of Health, Labour and Welfare) organized a Taskforce for intractable dise...

Autoantibodies against contactin ‐associated protein 1 and complexes of paranode‐specific proteins in chronic inflammatory demyelinating polyradiculoneuropathy
ConclusionsThis is the first confirmed Japanese case of anti-Caspr1 antibody-positive CIDP with a clinical signature similar to that of patients of Western origin. Our preliminary study did not identify the presence of specific antibodies against the paranode protein complexes, and the primary target antigen is likely Caspr1.

Level of CSF CXCL10 is highly elevated and decreased after steroid therapy in patients with autoimmune glial fibrillary acidic protein astrocytopathy
ConclusionCSF CXCL10 levels were particularly high in GFAP-A, and changes in levels after treatment correlated with clinical improvements, suggesting CXCL10 involvement in GFAP-A pathogenesis. (Source: Clinical and Experimental Neuroimmunology)

A case of natalizumab ‐associated progressive multifocal leukoencephalopathy followed by immune reconstitution inflammatory syndrome with difficulty in the timing of immunotherapy
ConclusionsTreatment sequencing should be executed before the onset of NAT-PML. Changes in CSF cell count and IgG index may be useful for treatment decision; further research is needed. (Source: Clinical and Experimental Neuroimmunology)

Japan MG Registry: chronological surveys over 10  years
AbstractThe primary purpose of the Japanese myasthenia gravis registry (JAMG-R) has been to research and promote high-quality medical care for MG patients in Japan. We reviewed the findings of surveys performed by JAMG-R over an approximately 10-year period. The first goal for favorable quality of life (QOL) is a status of minimal manifestations (MM) or better with an oral prednisolone (PSL) dose of 5 mg/day or less (MM-5 mg). Early and aggressive use of non-oral fast-acting treatment together with low-dose oral PSL (the “EFT strategy”) is recommended to reduce disease severity with minimal oral steroid use so that the...

Concentration ‐dependent effects of proinflammatory cytokines on barrier function and tight junction protein expression in brain microvascular endothelial cells and the hypothermic and hyperthermic effects on tight junction protein expression
ConclusionThe hypothermic suppression of TNF- α and IL-17 release may contribute to the maintenance of BBB function by ameliorating the decrease of TJP(s). In contrast, hyperthermia may decrease barrier function through a decrease in JAM-B expression. However, the contribution of changes in the JAM-B expression to the barrier function of BMVEC s remains to be clarified. (Source: Clinical and Experimental Neuroimmunology)
