Marburg Multiple Sclerosis
Marburg acute multiple sclerosis, also known as Marburg multiple sclerosis or acute fulminant multiple sclerosis, is considered one of the multiple sclerosis borderline diseases, which is a collection of diseases classified by some as MS variants and by others as different diseases. Other diseases in this group are neuromyelitis optica (NMO), Balo concentric sclerosis, and Schilder's disease. The graver course is one form of malignant multiple sclerosis, with patients reaching a significant level of disability in less than five years from their first symptoms, often in a matter of months. Sometimes Marburg MS is considered a synonym for tumefactive MS, but not for all authors. Pathogenesis Marburg MS has been reported to be closer to anti-MOG associated ADEM than to standard MS It has been reported to appear sometimes post-partum MOG antibody‐associated demyelinating pseudotumor Some anti-MOG cases satisfy the MS requirements (lesions disseminated in time and space) and a ...

Multiple Sclerosis
Multiple (cerebral) sclerosis (MS), also known as encephalomyelitis disseminata or disseminated sclerosis, is the most common demyelinating disease, in which the insulating covers of nerve cells in the brain and spinal cord are damaged. This damage disrupts the ability of parts of the nervous system to transmit signals, resulting in a range of signs and symptoms, including physical, mental, and sometimes psychiatric problems. Specific symptoms can include double vision, blindness in one eye, muscle weakness, and trouble with sensation or coordination. MS takes several forms, with new symptoms either occurring in isolated attacks (relapsing forms) or building up over time (progressive forms). In the relapsing forms of MS, between attacks, symptoms may disappear completely, although some permanent neurological problems often remain, especially as the disease advances. While the cause is unclear, the underlying mechanism is thought to be either destruction by the immune system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiple Sclerosis Borderline
Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) due to the unknown etiology of some of them, are a heterogenous group of demyelinating diseases - conditions that cause damage to myelin, the protective sheath of nerve fibers - that occur against the background of an acute or chronic inflammatory process. IDDs share characteristics with and are often grouped together under Multiple Sclerosis. They are sometimes considered different diseases from Multiple Sclerosis, but considered by others to form a spectrum differing only in terms of chronicity, severity, and clinical course. Multiple sclerosis for some people is a syndrome more than a single disease. As of 2019, three auto-antibodies have been found in atypical MS giving birth to separate diseases: Anti-AQP4 diseases, Anti-MOG and Anti-NF spectrums. A LHON-associated MS has also been reported, and in addition there have been inconclusive reports of TNF-α blockers inducing demyelinating disord ...

Devic's Disease
Neuromyelitis optica spectrum disorders (NMOSD), including neuromyelitis optica (NMO), are autoimmune diseases characterized by acute inflammation of the optic nerve (optic neuritis, ON) and the spinal cord (myelitis). Episodes of ON and myelitis can be simultaneous or successive. A relapsing disease course is common, especially in untreated patients. In more than 80% of cases, NMO is caused by immunoglobulin G autoantibodies to aquaporin 4 ( anti-AQP4), the most abundant water channel protein in the central nervous system. A subset of anti-AQP4-negative cases is associated with antibodies against myelin oligodendrocyte glycoprotein ( anti-MOG). Rarely, NMO may occur in the context of other autoimmune diseases (e.g. connective tissue disorders, paraneoplastic syndromes) or infectious diseases. In some cases, the etiology remains unknown (idiopathic NMO). Multiple sclerosis (MS) and NMO can be similar in clinical and radiological presentation, and MS may very rarely present w ...

Balo Concentric Sclerosis
Baló's concentric sclerosis is a disease in which the white matter of the brain appears damaged in concentric layers, leaving the axis cylinder intact. It was described by József Mátyás Baló who initially named it "leuko-encephalitis periaxialis concentrica" from the previous definition, and it is currently considered one of the borderline forms of multiple sclerosis. Baló's concentric sclerosis is a demyelinating disease similar to standard multiple sclerosis, but with the particularity that the demyelinated tissues form concentric layers. Scientists used to believe that the prognosis was similar to Marburg multiple sclerosis, but now they know that patients can survive, or even have spontaneous remission and asymptomatic cases. The concentric ring appearance is not specific to Baló's MS. Concentric lesions have also been reported in patients with neuromyelitis optica, standard MS, progressive multifocal leukoencephalopathy, cerebral autosomal dominant arteriopathy with su ...

Diffuse Myelinoclastic Sclerosis
Diffuse myelinoclastic sclerosis, sometimes referred to as Schilder's disease, is a very infrequent neurodegenerative disease that presents clinically as pseudotumoural demyelinating lesions, making its diagnosis difficult. It usually begins in childhood, affecting children between 5 and 14 years old, but cases in adults are also possible. This disease is considered one of the borderline forms of multiple sclerosis because some authors consider them different diseases and others MS variants. Other diseases in this group are neuromyelitis optica (NMO), Balo concentric sclerosis and Marburg multiple sclerosis. Symptoms and signs Symptoms are similar to those in multiple sclerosis and may include dementia, aphasia, seizures, personality changes, poor attention, tremors, balance instability, incontinence, muscle weakness, headache, vomiting, and vision and speech impairment. Diagnostic The Poser criteria for diagnosis are: * One or two roughly symmetrical large plaques. Plaques are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malignant Multiple Sclerosis
Malignant multiple sclerosis is used to describe MS patients who reach significant level of disability in a short period of time. Malignant MS cases are not common, less than 5% of patients with MS experience this type of progression.Kimiskidis, V., Sakellari, I., Tsimourtou, V., Kapina, V., Papagiannopoulos, S., Kazis, D., Vlaikidis, N., Anagnostopoulos, A., & Fassas, A. & Fassas, A. (2008). Autologous stem-cell transplantation in malignant multiple sclerosis: a case with a favorable long-term outcome. ''Multiple Sclerosis (Houndmills, Basingstoke, England)'', ''14''(2), 278–283. The National MS Society Advisory Committee on Clinical Trials of New Agents consensus defined it as: disease with a rapid progressive course, leading to significant disability in multiple neurologic systems or death in a relatively short time after disease onset. Reaching Expanded Disability Status Scale of 6.0 or higher, which is equivalent of needing unilateral support to ambulate (or worse) is gene ...

Tumefactive MS
Tumefactive multiple sclerosis is a condition in which the central nervous system of a person has multiple demyelinating lesions with atypical characteristics for those of standard multiple sclerosis (MS). It is called tumefactive as the lesions are "tumor-like" and they mimic tumors clinically, radiologically and sometimes pathologically. These atypical lesion characteristics include a large intracranial lesion of size greater than 2.0 cm with a mass effect, edema and an open ring enhancement. A mass effect is the effect of a mass on its surroundings, for example, exerting pressure on the surrounding brain matter. Edema is the build-up of fluid within the brain tissue. Usually, the ring enhancement is directed toward the cortical surface.Kaeser, M. A., Scali, F., Lanzisera, F. P., Bub, G. A., and Kettner, N. W. Tumefactive multiple sclerosis: an uncommon diagnostic challenge. ''Journal of Chiropractic Medicine'' 10:29-35 (2011). The tumefactive lesion may mimic a malignant ...

Anti-MOG Associated Encephalomyelitis
MOG antibody disease (MOGAD) or MOG antibody-associated encephalomyelitis (MOG-EM) is an inflammatory demyelinating disease of the central nervous system. Serum anti-myelin oligodendrocyte glycoprotein antibodies are present in up to half of patients with an acquired demyelinating syndrome and have been described in association with a range of phenotypic presentations, including acute disseminated encephalomyelitis, optic neuritis, transverse myelitis, and neuromyelitis optica. Presentation The clinical presentation is variable and largely dependent upon the overall clinical manifestation. The presence of anti-MOG autoantibodies has been described in association with the following conditions: * Seronegative neuromyelitis optica. * Acute disseminated encephalomyelitis, especially in recurrent and fulminant cases. * Multiple sclerosis. * Optic neuritis(including cases of CRION (chronic relapsing inflammatory optic neuropathy) * Transverse myelitis * Aseptic meningitis and meningoenc ...

Otto Marburg
Otto Marburg (May 25, 1874 – June 13, 1948) was an Austrian neurologist known for his contributions to the understanding of multiple sclerosis and for advances in neurooncology. Marburg was born in Römerstadt in Moravia, Austria-Hungary (today Rýmařov, Czech Republic). He was Jewish.Lewis P. Rowland, ''The legacy of Tracy J. Putnam and H. Houston Merritt: modern neurology in the United States'', Oxford University Press (2008), p. 62 From 1919 to 1938 he was head of the Neurological Institute at the University of Vienna. Following the 1938 Anschluss, Marburg was forced to emigrate to the United States as a refugee. Arriving in New York City, he joined Columbia University's College of Physicians and Surgeons as clinical professor of neurology. He was author of several standard texts about the nervous system, and a subtype of multiple sclerosis (Marburg multiple sclerosis) has been named after him. Marburg died of cancer in New York in 1948, at the age of 74. Otto Mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitoxantrone
Mitoxantrone (INN, BAN, USAN; also known as Mitozantrone in Australia; trade name Novantrone) is an anthracenedione antineoplastic agent. Uses Mitoxantrone is used to treat certain types of cancer, mostly acute myeloid leukemia. It improves the survival rate of children suffering from acute lymphoblastic leukemia relapse. The combination of mitoxantrone and prednisone is approved as a second-line treatment for metastatic hormone-refractory prostate cancer. Until recently this combination was the first line of treatment; however, a combination of docetaxel and prednisone improves survival rates and lengthens the disease-free period. Mitoxantrone is also used to treat multiple sclerosis (MS), most notably the subset of the disease known as secondary-progressive MS. In the absence of a cure, mitoxantrone is effective in slowing the progression of secondary-progressive MS and extending the time between relapses in both relapsing-remitting MS and progressive-relapsing MS.

Alemtuzumab
Alemtuzumab, sold under the brand names Campath and Lemtrada among others, is a medication used to treat chronic lymphocytic leukemia (CLL) and multiple sclerosis. In CLL, it has been used as both a first line and second line treatment. In MS it is generally only recommended if other treatments have not worked. It is given by injection into a vein. It is a monoclonal antibody that binds to CD52, a protein present on the surface of mature lymphocytes, but not on the stem cells from which these lymphocytes are derived. After treatment with alemtuzumab, these CD52-bearing lymphocytes are targeted for destruction. Alemtuzumab was approved for medical use in the United States in 2001. (Mab)Campath was withdrawn from the markets in the US and Europe in 2012, to prepare for a higher-priced relaunch of Lemtrada aimed at multiple sclerosis. Medical uses Chronic lymphocytic leukemia Alemtuzumab is used for the treatment of B-cell chronic lymphocytic leukemia (B-CLL) in people who have ...

Autologous Stem Cell Transplantation
Autologous stem-cell transplantation (also called autogenous, autogeneic, or autogenic stem-cell transplantation and abbreviated auto-SCT) is autologous transplantation of stem cells—that is, transplantation in which stem cells ( undifferentiated cells from which other cell types develop) are removed from a person, stored, and later given back to that same person. Although it is most frequently performed with hematopoietic stem cells (precursors of blood-forming cells) in hematopoietic stem cell transplantation, cardiac cells have also been used successfully to repair damage caused by heart attacks. Autologous stem-cell transplantation is distinguished from allogenic stem cell transplantation where the donor and the recipient of the stem cells are different people. See also * Autologous hematopoietic stem-cell transplantation * Stem-cell therapy Stem-cell therapy is the use of stem cells to treat or prevent a disease or condition. , the only established therapy using st ...
