Monoclonal antibody-associated progressive multifocal leucoencephalopathy in patients treated with rituximab, natalizumab, and efalizumab: a Review from the Research on Adverse Drug Events and Reports (RADAR) Project.

Progressive multifocal leucoencephalopathy (PML) is a serious and usually fatal CNS infection caused by JC polyoma virus. CD4+ and CD8+ T lymphopenia, resulting from HIV infection, chemotherapy, or immunosuppressive therapy, are the primary risk factors. The immune modulatory monoclonal antibodies rituximab, natalizumab, and efalizumab have received regulatory approval in the USA and Europe for treatment of non-Hodgkin lymphoma, rheumatoid arthritis, and chronic lymphocytic leukaemia (Europe only); multiple sclerosis and Crohn's disease; and psoriasis, respectively. Efalizumab and natalizumab …

Craniospinal dissemination of clival chondroid chordoma.

Chondroid chordoma commonly presents as clival osseous and extradural mass. A 15-year-old boy presented with progressive visual deficit, headaches and diplopia since three years. Computed tomography (CT scan) showed a skull base tumour, but was wrongly reported at the time as chronic sphenoidal sinusitis and nasal polyps. In the past three months, he developed dysphagia, urinary retention and constipation. Terminally, he had weakness of all limbs. Fundoscopy showed optic atrophy. Temporal and spatial variation in symptoms led to a clinical diagnosis of multiple sclerosis with optic neuritis. P…

Progressive systemic sclerosis associated with multiple mononeuropathy.

BACKGROUND: Progressive systemic sclerosis (PSS) is a chronic connective tissue inflammatory disease which commonly attacks the skin and the visceral organs, but rarely the peripheral nervous system. OBJECTIVE: The aim of this study was to investigate PSS accompanied by peripheral neuropathy clinically, electrophysiologically and pathologically from a sural nerve biopsy. METHODS: Two women suffering from PSS but without any other collagen disease were studied. Both patients developed peripheral neuropathy with multiple mononeuropathy of the limbs, and in one woman, in the trunk as well. RES

Thrombomodulin in the sera of patients with multiple sclerosis and human lymphotropic virus type-1-associated myelopathy.

Damage to the blood-brain barrier, which mainly consists of cerebral endothelial cells, has been demonstrated in multiple sclerosis (MS) clinically and histochemically. To investigate the endothelial cell damage, we evaluated the presence of soluble thrombomodulin in the sera of patients with MS and human T lymphotropic virus type-1-associated myelopathy (HAM) using an enzyme-linked immunosorbent assay. Serum thrombomodulin levels were significantly increased in patients with acute relapsing MS during an exacerbation and chronic progressive MS as compared with those of controls (P < 0.001, res…

Chronic progressive neurological involvement in Borrelia burgdorferi infection.

Five patients with chronic meningitis were hospitalized several times for progressive neurological symptoms. The clinical manifestations included cranial neuritis, radiculoneuritis, myelitis and encephalitis. In two cases cerebral infarction occurred. The course was commonly characterized by a tendency to deteriorate. From the clinical point of view, it was repeatedly difficult to exclude multiple sclerosis or tuberculous meningitis. Finally, specific antibodies against Borrelia burgdorferi were detected by indirect immunofluorescence assay. The diagnosis of a borreliosis was not considered in…

Network pharmacology and bioinformatics reveal multi-target neuroprotective mechanisms of Radix Bupleuri in multiple sclerosis via CASP8, HSP90AA1, CDK4, and MDM2.

BACKGROUND: Multiple sclerosis (MS) is a chronic, autoimmune, central nervous system disorder associated with demyelination and neuroinflammation. Current treatments decrease the risk of relapse, but are not always effective in preventing disease progression. Traditional Chinese medicine (TCM) has been known for multi-target activities, and Radix Bupleuri (RB) could be used in immune and inflammation system. METHODS: A systems pharmacology approach was employed to screen the bioactive components of Radix Bupleuri based on pharmacokinetic parameters. Multiple sclerosis-related gene sets were o…

Bacoside-A inhibits inflammatory cytokines and chemokine in experimental autoimmune encephalomyelitis.

Chronic inflammation of the myelin sheath is the crucial event behind the progression of multiple sclerosis (MS). Bacoside-A is one of the major constituents obtained from Bacopa monerii (L.) Wettst., and possess neuroprotective as well as anti-inflammatory actions. The current study explores the effect of Bacoside-A in acute and chronic models of Experimental Autoimmune Encephalomyelitis (EAE). The results indicate that the Bacoside-A treated mice produced a significant reduction in disease score compared to disease control in both models. The treatment with Bacoside-A downregulated the infla…

Gastrointestinal Manifestations, Malnutrition, and Role of Enteral and Parenteral Nutrition in Patients With Scleroderma.

Scleroderma (systemic sclerosis) is an autoimmune disease that can affect multiple organ systems. Gastrointestinal (GI) involvement is the most common organ system involved in scleroderma. Complications of GI involvement including gastroesophageal reflux disease, small intestinal bacterial overgrowth, and chronic intestinal pseudoobstruction secondary to extensive fibrosis may lead to nutritional deficiencies in these patients. Here, we discuss pathophysiology, progression of GI manifestations, and malnutrition secondary to scleroderma, and the use of enteral and parenteral nutrition to revers

Glial cells in chronic inflammation: diversity, dysfunction and therapeutic targeting.

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS). Current therapies for relapsing MS primarily target the peripheral immune system but have consistently failed to address mechanisms underlying disease progression, which are thought to involve CNS-resident glial cells such as astrocytes, microglia and oligodendrocytes. Recent technological advances have revealed the functional heterogeneity of these glial cells, highlighting their crucial roles in inflammation, demyelination, remyelination and neurodegeneration. In this Review, we summarize emerging …

Механизмы и новые регулирующие органы нейроинфламмации: изучение новых терапевтических стратегий в отношении неврологических расстройств.

Нейроинфламмация представляет собой сложную и динамичную реакцию центральной нервной системы (КНС) на травмы, инфекцию и болезни. В то время как острая нейроинфламмация играет защитную роль, облегчая расчистку патогенов и восстановление тканей, хроническая и дисрегулированная воспаление в значительной степени способствует развитию таких нейродегенеративных расстройств, как болезнь Альцгеймера, болезнь Паркинсона и множественный склероз. В рамках этого обзора изучаются клеточные и молекулярные механизмы, лежащие в основе нейроинфламмации, с уделением особого внимания роли микроглий, астроцитов

Microglia-associated progression of multiple sclerosis: target identification and therapeutic engagement in human in vitro models.

Chronic progression of multiple sclerosis (MS) is likely to develop on the basis of a highly complex interaction of different mechanisms, which are probably already present at disease onset. While animal models have been instrumental in developing therapies for relapsing forms of MS, they have provided limited insight into the processes driving disease progression. To overcome these limitations, human in vitro models have emerged as powerful tools to dissect cellular mechanisms and identify novel therapeutic targets. Here, we highlight advances in modeling MS progression, using human induced p…

[Multiple sclerosis. An update with practical guidelines for ophthalmologists].

Multiple sclerosis (MS) is the most frequent chronic inflammatory disease of the central nervous system. Mostly young adults present with a variety of different symptoms due to the multiple localisations of the inflammatory lesions. Up to one-third of MS patients experience symptoms of optic neuritis as the initial symptom. That is the reason why the ophthalmologist often is the first physician contacted by patients later on diagnosed with MS. Today, it is known that there is already a significant irreversible axonal loss in MS patients progressing from the beginning of the disease. Therefore …

Measuring cognitive change in secondary progressive MS: an analysis of the ASCEND cognition substudy.

BACKGROUND: Cognitive impairment is common in multiple sclerosis (MS). Accurate measurement of cognitive change is essential for clinical trials. METHODS: The change in cognitive scores, clinical metrics of physical disability, and neuroradiological metrics was quantified in data from a phase-3 randomized controlled trial of natalizumab in secondary progressive MS (SPMS). The adults diagnosed with SPMS for ≥ 2 years and Expanded Disability Status Scale (EDSS) scores from 3 to 6.5 were randomized to receive natalizumab or placebo for 96 weeks. We evaluated change in Symbol Digit Modalities Tes…

A transgenic model of central nervous system autoimmunity mediated by CD4+ and CD8+ T and B cells.

Experimental autoimmune encephalomyelitis (EAE) is a widely used model of multiple sclerosis. In NOD mice, EAE develops as a relapsing-remitting disease that transitions to a chronic progressive disease, making the NOD model the only mouse model that recapitulates the full clinical disease course observed in most multiple sclerosis patients. We have generated a TCR transgenic mouse that expresses the α- and β-chains of a myelin oligodendrocyte glycoprotein (MOG) 35-55-reactive TCR (1C6) on the NOD background. 1C6 TCR transgenic mice spontaneously generate both CD4(+) and CD8(+) T cells that re…

Topographical Variation of Iron-Rimmed Lesions in the Multiple Sclerosis Brain and Spinal Cord: A Neuropathological Study.

Paramagnetic-rim lesions are a novel diagnostic marker in multiple sclerosis (MS) and are associated with poor prognosis due to their link with chronic inflammation and disease progression. Analyzing 46 postmortem MS cases, researchers found no iron rims in 67 white matter and 85 grey matter spinal cord lesions, despite most being active. In contrast, iron rims appeared in 20.9% of cortical and 80% of subcortical brain lesions, especially in deeper myelin-rich cortical layers. These findings highlight the regional variability of iron accumulation and have important implications for interpretin…

Non-invasive Detection of Persistent Cortical Hypoxia in Multiple Sclerosis Using Frequency Domain Near-Infrared Spectroscopy (fdNIRS).

There may be a relationship between hypoxia and inflammation, which is important in the outcomes of a wide array of human diseases. Multiple sclerosis (MS) is one such disease. There is evidence that hypoxia may influence inflammation in MS. We showed previously that about 40% of participants with MS had hypoxia in the cortical grey matter using frequency-domain near-infrared spectroscopy (fdNIRS). In this study, we aimed to determine if hypoxia in MS persists chronically (for a year or more) by measuring at baseline and ≥12 months later. We found that hypoxia persists for at least a year in 8…

Deficits in Social Cognition: An Unveiled Signature of Multiple Sclerosis.

BACKGROUND AND OBJECTIVES: Multiple sclerosis (MS) is a chronic progressive inflammatory disease of the central nervous system, representing the primary cause of non-traumatic disability in young adults. Cognitive dysfunction can affect patients at any time during the disease process and might alter the six core functional domains. Social cognition is a multi-component construct that includes the theory of mind, empathy and social perception of emotions from facial, bodily and vocal cues. Deficits in this cognitive faculty might have a drastic impact on interpersonal relationships and quality …
