Malignant multiple sclerosis

Last updated

Malignant multiple sclerosis is used to describe MS patients who reach significant level of disability in a short period of time. [1] Malignant MS cases are not common, less than 5% of patients with MS experience this type of progression. [2]

Contents

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. [3] Reaching Expanded Disability Status Scale of 6.0 or higher, which is equivalent of needing unilateral support to ambulate [4] (or worse) is generally considered this significant disability level. [5]

Patients with severe forms of more common relapsing remitting or progressive MS subtypes, as well as rare Marburg variant and Balo concentric sclerosis, could be considered to have malignant MS. Patients should be carefully worked up to rule out Neuromyelitis optica (Devic's disease) due to the distinctive pathophysiology and management strategies of this disease. [6]

Signs and symptoms

Some common physical symptoms may include: "weakness in extremities, difficulties with coordination and balance, spasticity, paresthesia, speech impediments, tremors, dizziness, hearing loss, vision impairments, bowel and bladder difficulties" [7]

Diagnosis

Earlier signs include an increase in mobility over a short period of time. Malignant MS happens in patients that already have or have been diagnosed with MS. There is not a specific test to detect malignant MS; it is often confused with acute disseminated encephalomyelitis.

Malignant MS is diagnosed after clinical investigations. Doctors may access the symptoms and to rule out other disorders, a neurological exam is performed. Further diagnostics may include an analysis of the cerebrospinal fluid. [8]

Neurological testing may also be performed, such as "a magnetic resonance imaging (MRI), diffusion-tensor magnetic resonance imaging (DT-MRI), and computerized brain tomography are used to detect central nervous system lesions, myelin loss, white matter abnormalities, and other physical changes in the brain." [8]

Treatment

Currently, there is no cure for malignant MS; however, "immunomodulatory therapy and other physical occupational therapies can help the management of symptoms and help them more easily perform everyday tasks such as handwriting, buttoning, and using eating utensils." [9]

Some mobility aids, such as canes, walkers, and wheelchairs may also be helpful as well for patients struggling with balance and walking. [9]

MOG antibody‐associated demyelinating pseudotumor

Some anti-MOG cases satisfy the MS requirements (lesions disseminated in time and space) and are therefore traditionally considered MS cases. After the discovery of the anti-MOG disease this classification is into revision. [10]

Autologous stem cell transplantation

Anecdotal evidence shows that autologous stem-cell transplantation, intensive immunosuppression combined with autologous stem cell therapy, may be an effective means for treating this life-threatening condition. The process of this therapy entails plasmapheresis or immunosuppression with mitoxantrone, cyclophosphamide, cladribine or bone marrow transplantation. In one study on a 17-year-old patient, researchers tried treating the patient with high-dose chemotherapy plus anti-thymocyte globulin followed by autologous stem cell transplantation. The findings of this study were positive. After being treated with a methylprednisolone (mPDN) i.v, the patient improved significantly. When the patient began to relapse/remit, they were treated again, resulting in improvement. After this, the patient remained stable for roughly 7 months before suffering their third relapse/remit. [11]

This therapy may be a therapy option for patients with malignant MS. [11]

Acute disseminated encephalomyelitis (ADEM), or acute demyelinating encephalomyelitis, is a rare autoimmune disease marked by a sudden, widespread attack of inflammation in the brain and spinal cord. As well as causing the brain and spinal cord to become inflamed, ADEM also attacks the nerves of the central nervous system and damages their myelin insulation, which, as a result, destroys the white matter. The cause is often a trigger such as from viral infection or vaccinations.

<span class="mw-page-title-main">Multiple sclerosis</span> Disease that damages the myelin sheaths around nerves

Multiplesclerosis (MS) 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, visual loss, muscle weakness, and trouble with sensation or coordination. MS takes several forms, with new symptoms either occurring in isolated attacks or building up over time. In the relapsing forms of MS, between attacks, symptoms may disappear completely, although some permanent neurological problems often remain, especially as the disease advances.

Interferon beta-1a is a cytokine in the interferon family used to treat multiple sclerosis (MS). It is produced by mammalian cells, while interferon beta-1b is produced in modified E. coli. Some research indicates that interferon injections may result in an 18–38% reduction in the rate of MS relapses.

<span class="mw-page-title-main">Hematopoietic stem cell transplantation</span> Medical procedure to replace blood or immune stem cells

Hematopoietic stem-cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood in order to replicate inside of a patient and to produce additional normal blood cells. It may be autologous, allogeneic or syngeneic.

Neuromyelitis optica spectrum disorders (NMOSD), including neuromyelitis optica (NMO), are autoimmune diseases characterized by acute inflammation of the optic nerve 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 or infectious diseases. In some cases, the etiology remains unknown.

Interferon beta-1b is a cytokine in the interferon family used to treat the relapsing-remitting and secondary-progressive forms of multiple sclerosis (MS). It is approved for use after the first MS event. Closely related is interferon beta 1a, also indicated for MS, with a very similar drug profile.

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.

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease that affects the central nervous system (CNS). Several therapies for it exist, although there is no known cure.

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.

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.

Research in multiple sclerosis may find new pathways to interact with the disease, improve function, curtail attacks, or limit the progression of the underlying disease. Many treatments already in clinical trials involve drugs that are used in other diseases or medications that have not been designed specifically for multiple sclerosis. There are also trials involving the combination of drugs that are already in use for multiple sclerosis. Finally, there are also many basic investigations that try to understand better the disease and in the future may help to find new treatments.

<span class="mw-page-title-main">Tumefactive multiple sclerosis</span> Medical condition

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.

<span class="mw-page-title-main">Multiple sclerosis diagnosis</span>

Current standards for diagnosing multiple sclerosis (MS) are based on the 2018 revision of McDonald criteria. They rely on MRI detection of demyelinating lesions in the CNS, which are distributed in space (DIS) and in time (DIT). It is also a requirement that any possible known disease that produces demyelinating lesions is ruled out before applying McDonald's criteria.

<span class="mw-page-title-main">Pathology of multiple sclerosis</span> Pathologic overview

Multiple sclerosis (MS) can be pathologically defined as the presence of distributed glial scars (scleroses) in the central nervous system that must show dissemination in time (DIT) and in space (DIS) to be considered MS lesions.

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.

There are several ways for pharmaceuticals for treating multiple sclerosis (MS) to reach the market.

Several biomarkers for diagnosis of multiple sclerosis, disease evolution and response to medication are under research. While most of them are still under research, there are some of them already well stablished:
