Optic nerve as a 5th location in the revised McDonald diagnostic criteria for multiple sclerosis: limitations of OCT in the acute phase.

BACKGROUND: The updated International Panel's diagnostic criteria for multiple sclerosis (2024 revision of McDonald criteria) have for the first time included the optic nerve as the fifth location for dissemination in space (DIS) criterion. The new requirement consists of evidence of significant retinal asymmetry. However, this can be challenging in the acute phase in absence of optic disc swelling. Here, we have investigated the sensitivity of retinal asymmetry over time, from the acute to the chronic phase of optic neuritis. METHODS: This observational study analysed longitudinal optical co…

Comorbidity and modifiable risk factors in multiple sclerosis.

Multi-system comorbidities are common in patients with multiple sclerosis (PwMS) and significantly influence the disease's presentation and progression. A comorbidity is defined as an illness other than the specific disease of interest (in this case, MS). Generally, chronic or recurrent conditions are included, while transient conditions such as infection or concussion are excluded. Certain modifiable metabolic diseases in PwMS, such as hypertension, diabetes, dyslipidemia, and modifiable health factors such as smoking, alcohol, and obesity, are also considered part of MS comorbidity in this r…

Validity of serum neurofilament light chain as a prognostic biomarker of disease activity in multiple sclerosis.

Multiple sclerosis (MS) is a chronic demyelinating and neuroinflammatory disease of the human central nervous system with complex pathoetiology, heterogeneous presentations and an unpredictable course of disease progression. There remains an urgent need to identify and validate a biomarker that can reliably predict the initiation and progression of MS as well as identify patient responses to disease-modifying treatments/therapies (DMTs). Studies exploring biomarkers in MS and other neurodegenerative diseases currently focus mainly on cerebrospinal fluid (CSF) analyses, which are invasive and i…

The Multiple Sclerosis Severity Score: associations with MC1R single nucleotide polymorphisms and host response to ultraviolet radiation.

BACKGROUND: Multiple sclerosis outcome may be influenced by ultraviolet radiation and vitamin D synthesis, suggesting skin type and genes determining this phenotype are candidates for disability. However, though associations between melanocortin 1 receptor (MC1R) single nucleotide polymorphisms and disability are reported, some data are incompatible with their expected influence on skin type. OBJECTIVE: Determine which MC1R single nucleotide polymorphisms affect disability and establish if ultraviolet radiation modifies such associations. METHODS: We studied using linear regression in 525 ca…

Secondary progressive in contrast to relapsing-remitting multiple sclerosis patients show a normal CD4+CD25+ regulatory T-cell function and FOXP3 expression.

Accumulating evidence indicates an immunosuppressive role for CD4(+)CD25(+) regulatory T cells (Tregs) in autoimmune diseases. Although an impaired Treg function in patients with relapsing-remitting multiple sclerosis (RR-MS) has been reported recently, no information is available so far about Treg function in the progressive stage of the disease. In the present study, the phenotypic and functional characteristics of CD4(+)CD25(+) T cells isolated from the peripheral blood of patients with RR-MS and secondary progressive multiple sclerosis (SP-MS) were investigated. No significant quantitative…

Similar low frequency of anti-MOG IgG and IgM in MS patients and healthy subjects.

The authors used a liquid-phase radiobinding assay to measure serum anti-myelin oligodendrocyte protein (MOG) immunoglobulin (Ig) G in 87 patients with multiple sclerosis (MS), in 12 patients with encephalomyelitis, and in 47 healthy subjects. Anti-MOG IgM was determined in samples obtained at onset from 40 of 87 patients with MS and in control subjects. The frequency of positive samples with low titers of anti-MOG IgG (< or =5.7%) and IgM (< or =8.3%) was similar in all the groups and subgroups. Binding competition experiments showed that these antibodies had low affinity. Anti-MOG antibodies…

METHODS: We recruited 75 RRMS patients and 75 subjects as controls with the same age and sex. Homocysteine was measured using fluorimetric high-performance liquid chromatography. Plasma folate and vitamin B12 levels were measured through ion-capture method. RESULTS: Mean plasm

[A neuropsychological and functional brain imaging study of visuo-imitative apraxia].

We describe the case of a 58-years-old right-handed women suffering from an occipital-parietal lesion. The administration of a cognitively based assessment tool for limb praxis (Batterie d'Evaluation des Praxies, B.E.P., Peigneux and Van der Linden, 1998) demonstrated bilateral visuo-imitative apraxia. Gesture production was mainly characterised by spatial, errors, and imitation of meaningful gestures was worse than their pantomime on verbal command. Moreover, the imitation of meaningless gestures and their reproduction on a manikin were worse than imitation of their matched meaningful gesture

Therapeutic immune tolerance for central nervous system autoimmune diseases - Prospects, challenges and pitfalls.

Autoimmune diseases of the central nervous system (CNS), including multiple sclerosis (MS), neuromyelitis optica spectrum disorders (NMOSD), and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD), are characterized by chronic inflammation driven by autoreactive immune responses against CNS antigens. Successes in the development of efficacious immunotherapies are hampered by the risks of broad immunosuppression and the consequences of compromising physiological immune functions. Antigen-specific immune tolerance offers a promising alternative by selectively silencing pathog…

Генетическое или терапевтическое нарушение траектории подачи сигналов Reelin/Apoer2 улучшает воспалительные результаты артрита.

Ремутатоидный артрит (RA) — хроническое аутоиммунное заболевание, характеризующееся синновальным воспалением, образованием паннуса и постепенным совместным разрушением. Вспыльчивая среда в RA приводит к активации эндотелиальных клеток и к повышению регулирования молекул сцепления, что облегчает проникновение лейкоцитов в синовый. Релин, циркулирующий гликопротеин, ранее связанный с активацией эндотели и вербовкой лейкоцитов для лечения таких заболеваний, как атеросклероз и множественный склероз, стал потенциальным регулятором этих процессов. Однако его роль в патогенезе РА остается слабой. Зде

Nitric oxide in neuroinflammation and neurodegeneration: dual roles, inflammasome crosstalk, and biomarker opportunities.

Nitric oxide is a short-lived gas that plays a critical role in numerous physiological processes, including vascular regulation, neurotransmission, and immune responses. In the CNS NO's role is complex, as it can both protect and damage neurons. Microglia, the brain's resident macrophages, produce excessive NO in response to stimuli like endotoxins and cytokines, leading to chronic inflammation and neuronal damage associated with neurodegenerative diseases such as Alzheimer's, Parkinson's, multiple sclerosis, and amyotrophic lateral sclerosis. NO's dual role as a pro-inflammatory and anti-infl…

The presence of cerebellar B cell aggregates is associated with a specific chemokine profile in the cerebrospinal fluid in a mouse model of multiple sclerosis.

BACKGROUND: The presence of meningeal ectopic lymphoid structures (ELS) in a subgroup of patients diagnosed with secondary progressive multiple sclerosis (SPMS) corresponds to a pronounced cortical inflammation and an aggravated disease course. In MP4-induced experimental autoimmune encephalomyelitis (EAE), a mouse model of multiple sclerosis (MS), B cell aggregates develop in the central nervous system (CNS) in the chronic stage of the disease. Therefore, the model is suitable for studying key molecules of ELS development and maintenance. Here, we investigated whether there is a specific cyto…

Porphyromonas gingivalis усугубляет экспериментальный аутоиммунный энцефаломиэлит, проводя дифференциацию TH1 с помощью сигнала ZAP70/NF-IB.
