No validated treatment regimen has been established to date. Nearly 80% patients with CAA-ri/vasculitis improved after immunosuppressant therapy with corticosteroid and/or cyclophosphamide. Early treatment is essential to prevent irreversible sequelae in the brain.Anti-myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease belongs to a new spectrum of disease entities that cause acute inflammatory demyelinating lesions in the central nervous system. MOG antibody-associated disease presents with several phenotypes including optic neuritis, myelitis, neuromyelitis optica spectrum disorder, brain stem encephalitis, acute disseminated encephalitis, and cortical encephalitis. For the diagnosis, brain magnetic resonance imaging (MRI) and cerebrospinal fluid studies are required to prove inflammatory demyelination apart from the identification of anti-MOG antibodies using cell-based assays. Immunotherapy is an effective treatment strategy to prevent relapse.Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disorder primarily associated with optic neuritis, myelitis or area postrema syndrome. Several lines of evidence suggest that NMOSD is a humoral immune disease mainly caused by aquaporin-4 antibody and related complement-dependent cytotoxicity against astrocytes. Therefore, NMOSD is distinct from multiple sclerosis (MS). In the diagnosis of NMOSD, it is recommended to examine by high-sensitive cell-based assay targeting against M23-AQP4 but we always have to be careful for the possibility of false negative or false positive result due to each assay. To prevent relapse of the disease, it is best to avoid disease-modifying drugs used for treatment of MS because of possible acute exacerbation of the disease activity. Usually, it is recommended to start treatment with administration of oral steroids and then gradually move to immunosuppressants. However, side effects of such treatments need to be evaluated. Currently, there are additional options for therapy with biopharmaceutical agents such as eculizumab, satralizumab, rituximab, or inebilizumab to prevent relapse of the disease. These new options can clearly exceed or surpass the usual treatments and should be considered positively in aggressive cases of NMOSD.Absrtract Acute disseminated encephalomyelitis (ADEM) is an immune-mediated inflammatory demyelinating disorder of the central nervous system that predominantly affects the pediatric population, and it is characterized by an acute or subacute onset of multifocal neurological symptoms. ADEM is typically a monophasic illness, and the majority of cases are associated with either a preceding infection or vaccination. First-line therapy for the disease is intravenous administration of high-dose methylprednisolone, and the long-term prognosis of ADEM is generally favorable.Primary progressive multiple sclerosis (PPMS) is a chronic inflammatory disease of the central nervous system that leads to demyelination and neurodegeneration. PPMS is characterized by a gradual accumulation of disabilities that may occur from the initial disease onset. The pathological processes underlying PPMS are complex and include a variety of different mechanisms and pathways, including inflammation, axonal degeneration, microglial activation/oxidation byproducts, mitochondrial injury, and glutamate excitotoxicity. There is currently no disease-modifying drug approved for PPMS in Japan. However, ocrelizumab, a humanized anti-CD20 monoclonal antibody, has been approved for PPMS by the Food and Drug Administration. Immunology inhibitor In addition, some disease-modifying drugs have demonstrated significant efficacy in the treatment of PPMS in clinical trials.Secondary progressive multiple sclerosis (SPMS) is defined by the slowly progressive deterioration of clinical symptoms independent of relapse, following the early relapsing-remitting disease course. Diagnosis of SPMS is challenging and usually retrospective because of the lack of reliable diagnostic tests. There is also a lack of reliable clinical symptoms other than gait disturbance, which are well evaluated in the clinical setting. The pathogenic mechanisms driving SPMS are poorly understood, and therapy for SPMS remains limited. It is assumed that the characteristic features of neurodegeneration observed in SPMS are caused by chronic inflammation with compartmentalized T and B cells from the periphery, glial and mitochondrial dysfunction, and other factors. Neuroprotective agents, promotion of remyelination, and immunological modifications may be key targets for novel treatment strategies.Multiple sclerosis (MS) is an immune-mediated inflammatory demyelinating disease of the central nervous system. There are neither diagnostic tests nor markers for MS. Other causes must be excluded thoroughly before an MS diagnosis is considered definitive. The relapsing-remitting type is a major clinical course in MS. Most disease-modifying drugs (DMDs) target this clinical type. Many clinical studies have demonstrated that early intervention with DMDs may prevent disease progression and transition from relapsing-remitting MS to the secondary progressive type. There are windows of opportunity for DMDs. An adequate DMD should be used for the appropriate patient at the optimal time.It is well known that targeted therapies have led to a paradigm shift in the treatment of autoimmune/inflammatory diseases such as rheumatoid arthritis. Biologics use intravenous or subcutaneous injection because of their size (90-150 kDa) and target multiple cytokines such as TNF and IL-6, as well as cell surface functioning molecules such as CD28 and CD20. Orally available low-molecular weight products target intracellular signaling molecules, including JAK, BTK, and S1P1. Biologics and JAK inhibitors are novel and have new modes of action that effectively close the unmet medical needs of multiple autoimmune/inflammatory diseases. Furthermore, such targeted therapies have the potential to bring about a paradigm shift in the treatment of immune/inflammatory diseases of the central nervous system.Therapeutic apheresis is a valuable therapeutic option for various immune-mediated human disorders. Its therapeutic rationale is based on the removal of pathogenic autoantibodies and inflammatory molecules, such as complements, cytokines, and chemokines, that accelerate the disease activity. At the same time, other mechanisms of immune-modulatory effects have also been suggested. Therapeutic apheresis has been applied to Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, myasthenia gravis, and multiple sclerosis. For neuromyelitis optica spectrum disorder (NMOSD), in which anti-aquaporin 4 antibody plays a major pathogenic role, both plasma exchange and plasma adsorption are reported to be effective. Recently, the incidence and prevalence of autoimmune encephalitis have been increasingly reported in comparison to infective encephalitis, and these often respond to therapeutic apheresis. Therapeutic apheresis for immune-mediated neurological disorders is described in this section.High-dose intravenous immunoglobulin (IVIg) therapy has pharmacological suppressive actions against phagocytosis, complement system, pathogenic autoantibodies, and inflammatory cytokines, making it an effective treatment for autoimmune diseases. Unfortunately, there is no established evidence of the efficacy of IVIg therapy for autoimmune diseases of the central nervous system. Patients who are resistant to steroids and other immunosuppressive therapies or have complications that preclude the use of strong immunosuppressive therapies are considered eligible for IVIg therapy. The advantages of IVIg therapy include safety and ease of use. However, further evidence of the efficacy of IVIg treatment for autoimmune diseases of the central nervous system is warranted.Immunosuppressive agents (cytotoxic agents) may be effective in cases of central nervous system autoimmune/inflammatory diseases that do not respond to steroids, plasmapheresis, or intravenous immunoglobulin therapy. Cytotoxic drugs can cause serious side effects. Therefore, it is important to obtain adequate informed consent after a timely decision based on the indication has been made. It is important to be prepared in advance for opportunistic infections and adverse events and to closely monitor the subsequent course.Corticosteroids play an important role in the treatment of inflammatory disorders including neuroinflammatory diseases. Corticosteroids with glucocorticoid receptors directly regulate transcription of many genes associated with inflammation and interfere with pro-inflammatory transcription factors. Glucocorticoids produce non-genomic effects by intercalation into the plasma membrane. These effects differ depending on the immunophenotype of immune cells. The corticosteroid dosage that is effective against inflammatory disorders depends on the pathological background of autoimmune diseases; however, owing to limited clinical evidence, the dosage has been empirically determined in routine medical practice. The corticosteroid dosage should be less then 7.5mg prednisolone equivalent/day to reduce the risk of adverse effects associated with these drugs.Clinical Scenario Pathologies of the long head of the biceps brachii (LHB) tendon are a source of shoulder pain in many people. It is important to have a reliable assessment of the LHB tendon to make an accurate diagnosis and provide the correct treatment or referral if necessary. Shoulder ultrasound is very accurate in the diagnosis of rotator cuff tears. However, its ability to detect pathologies of the LHB tendon is still unclear. Clinical Question In patients with shoulder pain, can musculoskeletal ultrasound accurately diagnose LHB tendon pathologies? Summary of Key Findings Four high-quality cohort studies met inclusion criteria and were included in the critical appraisal. The STrengthening the Reporting of OBservational studies in Epidemiology checklist was used to score the articles on methodology and consistency. Three studies evaluated accuracy in diagnosis of full-thickness tears and found high sensitivity (SN) and specificity (SP). Three studies evaluated accuracy in diagnosis of partial-thickness tears and found low SN and negative predictive value, but high SP and positive predictive value. Two studies evaluated tendon subluxation/dislocation and found high SN and SP. Two studies evaluated tendinitis and found moderate SN and high SP. Clinical Bottom Line There is moderate to strong evidence to support the use of musculoskeletal ultrasound in diagnosis of LHB tendon pathology. Strength of Recommendation There is grade B evidence that musculoskeletal ultrasound can accurately diagnose full-thickness tears and tendon subluxation/dislocation; can rule in partial-thickness tears (based on SP and positive predictive value), but not rule out partial-thickness tears; and can rule in tendinitis (based on SP and positive predictive value), but not rule out tendinitis.This study examines the influence of wearing and perceiving colors in a cycling setting while also examining cortisol, heart rate, estimated maximum oxygen consumption, and subjective performance ratings. A total of 99 individuals completed the study, consisting of cortisol measurements, which compared baseline values to those after changing into a red or blue outfit, and a maximum cycling task performed wearing the same outfit while competing against a video opponent in red or blue. Each participant completed the protocol twice on separate days. Wearing a colored outfit showed no influence on cortisol levels. Regarding the cycling task, the participants wearing red had higher maximum heart rate values than when wearing blue. In addition, the results revealed increased maximum heart rate and maximum oxygen consumption values when perceiving an opponent in blue, especially when the participant also wore blue. No differences were found for the median heart rate or performance ratings.
