CIDP
Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired autoimmune disease of the peripheral nervous system characterized by progressive weakness and impaired sensory function in the legs and arms. The disorder is sometimes called chronic relapsing polyneuropathy (CRP) or chronic inflammatory demyelinating polyradiculoneuropathy (because it involves the nerve roots). CIDP is closely related to Guillain–Barré syndrome and it is considered the chronic counterpart of that acute disease. Its symptoms are also similar to progressive inflammatory neuropathy. It is one of several types of neuropathy. Types Several variants have been reported. Specially important are: * An asymmetrical variant of CIDP is known as Lewis-Sumner Syndrome. or MADSAM (multifocal acquired demyelinating sensory and motor neuropathy) * A variant with CNS involvement named combined central and peripheral demyelination (CCPD) Currently there is one special variant in which the CNS is also affect ...

Multifocal Motor Neuropathy
Multifocal motor neuropathy (MMN) is a progressively worsening condition where muscles in the extremities gradually weaken. The disorder, a pure motor neuropathy syndrome, is sometimes mistaken for amyotrophic lateral sclerosis (ALS) because of the similarity in the clinical picture, especially if muscle fasciculations are present. MMN is thought to be autoimmune. It was first described in the mid-1980s. Unlike ALS, which affects both upper and lower motor neuron pathways, MMN involves only the lower motor neuron pathway, specifically, the peripheral nerves emanating from the lower motor neurons. Definitive diagnosis is often difficult, and many MMN patients labor for months or years under an ALS diagnosis before finally getting a determination of MMN. MMN usually involves very little pain; however, muscle cramps, spasms and twitches can cause pain for some people. MMN is not fatal, and does not diminish life expectancy. Many patients, once undergoing treatment, only experience m ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Anti-neurofascin Demyelinating Diseases
Anti-neurofascin demyelinating diseases (anti-NF diseases) refers to health conditions engendered by auto-antibodies against neurofascins, which can produce both central and peripheral demyelination. Some cases of combined central and peripheral demyelination (CCPD) could be produced by them. * Chronic inflammatory demyelinating polyneuropathy: Some cases of CIDP are reported to be produced by auto-antibodies against several neurofascin proteins. These proteins are present in the neurons and four of them have been reported to produce disease: NF186, NF180, NF166 and NF155. * Neuromyelitis optica: NF auto antibodies can also appear in NMO cases. These antibodies are more related to the peripheral nervous demyelination, but they were also found in NMO. * Multiple sclerosis: Also antibodies against Neurofascins NF-155 can also appear in atypical multiple sclerosis and NF-186 could be involved in subtypes of MS yielding an intersection between both conditions. Around 10% of MS cases are ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Neurology
Neurology (from el, wikt:νεῦρον, νεῦρον (neûron), "string, nerve" and the suffix wikt:-logia, -logia, "study of") is the branch of specialty (medicine), medicine dealing with the diagnosis and treatment of all categories of conditions and disease involving the brain, the spinal cord and the peripheral nerves. Neurological practice relies heavily on the field of neuroscience, the scientific study of the nervous system. A neurologist is a physician specializing in neurology and trained to investigate, diagnose and treat neurological disorders. Neurologists treat a myriad of neurologic conditions, including stroke, seizures, movement disorders such as Parkinson's disease, autoimmune neurologic disorders such as multiple sclerosis, headache disorders like migraine and dementias such as Alzheimer's disease. Neurologists may also be involved in clinical research, clinical trials, and basic research, basic or translational research. While neurology is a nonsurgical sp ...

Rituximab
Rituximab, sold under the brand name Rituxan among others, is a monoclonal antibody medication used to treat certain autoimmune diseases and types of cancer. It is used for non-Hodgkin lymphoma, chronic lymphocytic leukemia (in non-geriatric patients), rheumatoid arthritis, granulomatosis with polyangiitis, idiopathic thrombocytopenic purpura, pemphigus vulgaris, myasthenia gravis and Epstein–Barr virus-positive mucocutaneous ulcers. It is given by slow injection into a vein. Biosimilars of Rituxan include Blitzima, Riabni, Ritemvia, Rituenza (F.K.A. Tuxella), Rixathon, Ruxience, and Truxima. Common side effects which often occur within two hours of the medication being given include rash, itchiness, low blood pressure, and shortness of breath. Infections are also common. Severe side effects include reactivation of hepatitis B in those previously infected, progressive multifocal leukoencephalopathy, toxic epidermal necrolysis, and death. It is unclear if use during pre ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cryoglobulinemia
Cryoglobulinemia is a medical condition in which the blood contains large amounts of pathological cold sensitive antibodies called cryoglobulins – proteins (mostly immunoglobulins themselves) that become insoluble at reduced temperatures. This should be contrasted with cold agglutinins, which cause agglutination of red blood cells. Cryoglobulins typically precipitate (clumps together) at temperatures below normal body temperatureand will dissolve again if the blood is heated. The precipitated clump can block blood vessels and cause toes and fingers to become gangrenous. While this disease is commonly referred to as cryoglobulinemia in the medical literature, it is better termed cryoglobulinemic disease for two reasons: 1) cryoglobulinemia is also used to indicate the circulation of (usually low levels of) cryoglobulins in the absence of any symptoms or disease and 2) healthy individuals can develop transient asymptomatic cryoglobulinemia following certain infections.

Immunoglobulin M
Immunoglobulin M (IgM) is one of several isotypes of antibody (also known as immunoglobulin) that are produced by vertebrates. IgM is the largest antibody, and it is the first antibody to appear in the response to initial exposure to an antigen. In humans and other mammals that have been studied, plasmablasts residing in the spleen are the main source for specific IgM production. History In 1937, an antibody was observed in horses hyper-immunized with pneumococcus polysaccharide that was much larger in size than the typical rabbit γ-globulin, with a molecular weight of 990,000 daltons. In accordance with its larger size, the new antibody was originally referred to as γ-macroglobulin, and subsequently termed as IgM—M for “macro”. The V domains of normal immunoglobulin are highly heterogeneous, reflecting their role in protecting against the great variety of infectious microbes, and this heterogeneity impeded detailed structural analysis of IgM. Two sources of homogen ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Acute Motor Axonal Neuropathy
Acute motor axonal neuropathy (AMAN) is a variant of Guillain–Barré syndrome. It is characterized by acute paralysis and loss of reflexes without sensory loss. Pathologically, there is motor axonal degeneration with antibody-mediated attacks of motor nerves and nodes of Ranvier. Signs and symptoms Causes A link to ''Campylobacter jejuni'' was suspected when a young girl was admitted to Second Teaching Hospital. She had become ill after feeding the family chickens. She developed acute paralysis and respiratory failure. Investigators discovered that several of the chickens in the home displayed similar symptoms and ''C. jejuni'' was found in their droppings. Several of the paralysis patients were found to have antibodies to ''C. jejuni'' and anti-GD1a antibodies, suggesting a link between the pathogen and the disease. In 2015, Zika virus was linked to AMAN. Diagnosis The syndrome typically presents as a progressive flaccid symmetric paralysis with areflexia, often causi ...

Polyradiculoneuropathy
Polyradiculoneuropathy describes a condition in which polyneuropathy and polyradiculopathy occur together. An example is Guillain–Barré syndrome. Treatment with a single course of intravenous immunoglobulin (IVIG) infusions has been demonstrated to be a potentially effective treatment (reported to have caused prolonged remission in a case associated with systemic lupus (Systemic lupus erythematosus Lupus, technically known as systemic lupus erythematosus (SLE), is an autoimmune disease in which the body's immune system mistakenly attacks healthy tissue in many parts of the body.

Monoclonal Gammopathy
Monoclonal gammopathy, also known as paraproteinemia, is the presence of excessive amounts of myeloma protein or monoclonal gamma globulin in the blood. It is usually due to an underlying immunoproliferative disorder or hematologic neoplasms, especially multiple myeloma. It is sometimes considered equivalent to plasma cell dyscrasia. The most common form of the disease is monoclonal gammopathy of undetermined significance. Causes Causes of paraproteinemia include the following: * Leukemias and lymphomas of various types, but usually B-cell non-Hodgkin lymphomas with a plasma cell component. ** Myeloma ** Plasmacytoma ** Lymphoplasmacytic lymphoma * Idiopathic (no discernible cause): some of these will be revealed as leukemias or lymphomas over the years. ** AL amyloidosis Diagnosis These are characterized by the presence of any abnormal protein that is involved in the immune system, which are most often immunoglobulins and are associated with the clonal proliferation of lympho ...
