A disorder of neuromuscular transmission characterized by weakness of cranial and skeletal muscles. Autoantibodies directed against acetylcholine receptors damage the motor endplate portion of the NEUROMUSCULAR JUNCTION, impairing the transmission of impulses to skeletal muscles. Clinical manifestations may include diplopia, ptosis, and weakness of facial, bulbar, respiratory, and proximal limb muscles. The disease may remain limited to the ocular muscles. THYMOMA is commonly associated with this condition. (Adams et al., Principles of Neurology, 6th ed, p1459)
Any autoimmune animal disease model used in the study of MYASTHENIA GRAVIS. Injection with purified neuromuscular junction acetylcholine receptor (AChR) (see RECEPTORS, CHOLINERGIC) components results in a myasthenic syndrome that has acute and chronic phases. The motor endplate pathology, loss of acetylcholine receptors, presence of circulating anti-AChR antibodies, and electrophysiologic changes make this condition virtually identical to human myasthenia gravis. Passive transfer of AChR antibodies or lymphocytes from afflicted animals to normals induces passive transfer experimental autoimmune myasthenia gravis. (From Joynt, Clinical Neurology, 1997, Ch 54, p3)
Surgical removal of the thymus gland. (Dorland, 28th ed)
Cell surface proteins that bind acetylcholine with high affinity and trigger intracellular changes influencing the behavior of cells. Cholinergic receptors are divided into two major classes, muscarinic and nicotinic, based originally on their affinity for nicotine and muscarine. Each group is further subdivided based on pharmacology, location, mode of action, and/or molecular biology.
A neoplasm originating from thymic tissue, usually benign, and frequently encapsulated. Although it is occasionally invasive, metastases are extremely rare. It consists of any type of thymic epithelial cell as well as lymphocytes that are usually abundant. Malignant lymphomas that involve the thymus, e.g., lymphosarcoma, Hodgkin's disease (previously termed granulomatous thymoma), should not be regarded as thymoma. (From Stedman, 25th ed)
A cholinesterase inhibitor with a slightly longer duration of action than NEOSTIGMINE. It is used in the treatment of myasthenia gravis and to reverse the actions of muscle relaxants.
Tumors or cancer of the THYMUS GLAND.
Enlargement of the thymus. A condition described in the late 1940's and 1950's as pathological thymic hypertrophy was status thymolymphaticus and was treated with radiotherapy. Unnecessary removal of the thymus was also practiced. It later became apparent that the thymus undergoes normal physiological hypertrophy, reaching a maximum at puberty and involuting thereafter. The concept of status thymolymphaticus has been abandoned. Thymus hyperplasia is present in two thirds of all patients with myasthenia gravis. (From Segen, Dictionary of Modern Medicine, 1992; Cecil Textbook of Medicine, 19th ed, p1486)
A disorder of neuromuscular transmission that occurs in a minority of newborns born to women with myasthenia gravis. Clinical features are usually present at birth or develop in the first 3 days of life and consist of hypotonia and impaired respiratory, suck, and swallowing abilities. This condition is associated with the passive transfer of acetylcholine receptor antibodies through the placenta. In the majority of infants the myasthenic weakness resolves (i.e., transient neonatal myasthenia gravis) although this disorder may rarely continue beyond the neonatal period (i.e., persistent neonatal myasthenia gravis). (From Menkes, Textbook of Child Neurology, 5th ed, p823; Neurology 1997 Jan;48(1):50-4)
Antibodies that react with self-antigens (AUTOANTIGENS) of the organism that produced them.
Drooping of the upper lid due to deficient development or paralysis of the levator palpebrae muscle.
A rapid-onset, short-acting cholinesterase inhibitor used in cardiac arrhythmias and in the diagnosis of myasthenia gravis. It has also been used as an antidote to curare principles.
Drugs that inhibit cholinesterases. The neurotransmitter ACETYLCHOLINE is rapidly hydrolyzed, and thereby inactivated, by cholinesterases. When cholinesterases are inhibited, the action of endogenously released acetylcholine at cholinergic synapses is potentiated. Cholinesterase inhibitors are widely used clinically for their potentiation of cholinergic inputs to the gastrointestinal tract and urinary bladder, the eye, and skeletal muscles; they are also used for their effects on the heart and the central nervous system.

A genus of the Torpedinidae family consisting of several species. Members of this family have powerful electric organs and are commonly called electric rays.
The synapse between a neuron and a muscle.
A visual symptom in which a single object is perceived by the visual cortex as two objects rather than one. Disorders associated with this condition include REFRACTIVE ERRORS; STRABISMUS; OCULOMOTOR NERVE DISEASES; TROCHLEAR NERVE DISEASES; ABDUCENS NERVE DISEASES; and diseases of the BRAIN STEM and OCCIPITAL LOBE.
A single, unpaired primary lymphoid organ situated in the MEDIASTINUM, extending superiorly into the neck to the lower edge of the THYROID GLAND and inferiorly to the fourth costal cartilage. It is necessary for normal development of immunologic function early in life. By puberty, it begins to involute and much of the tissue is replaced by fat.
Disorders that are characterized by the production of antibodies that react with host tissues or immune effector cells that are autoreactive to endogenous peptides.
One of the two major classes of cholinergic receptors. Nicotinic receptors were originally distinguished by their preference for NICOTINE over MUSCARINE. They are generally divided into muscle-type and neuronal-type (previously ganglionic) based on pharmacology, and subunit composition of the receptors.
Disorders that feature impairment of eye movements as a primary manifestation of disease. These conditions may be divided into infranuclear, nuclear, and supranuclear disorders. Diseases of the eye muscles or oculomotor cranial nerves (III, IV, and VI) are considered infranuclear. Nuclear disorders are caused by disease of the oculomotor, trochlear, or abducens nuclei in the BRAIN STEM. Supranuclear disorders are produced by dysfunction of higher order sensory and motor systems that control eye movements, including neural networks in the CEREBRAL CORTEX; BASAL GANGLIA; CEREBELLUM; and BRAIN STEM. Ocular torticollis refers to a head tilt that is caused by an ocular misalignment. Opsoclonus refers to rapid, conjugate oscillations of the eyes in multiple directions, which may occur as a parainfectious or paraneoplastic condition (e.g., OPSOCLONUS-MYOCLONUS SYNDROME). (Adams et al., Principles of Neurology, 6th ed, p240)
Ocular disorders attendant upon non-ocular disease or injury.
Paralysis of one or more of the ocular muscles due to disorders of the eye muscles, neuromuscular junction, supporting soft tissue, tendons, or innervation to the muscles.
Recording of the changes in electric potential of muscle by means of surface or needle electrodes.
An autoimmune disease characterized by weakness and fatigability of proximal muscles, particularly of the pelvic girdle, lower extremities, trunk, and shoulder girdle. There is relative sparing of extraocular and bulbar muscles. CARCINOMA, SMALL CELL of the lung is a frequently associated condition, although other malignancies and autoimmune diseases may be associated. Muscular weakness results from impaired impulse transmission at the NEUROMUSCULAR JUNCTION. Presynaptic calcium channel dysfunction leads to a reduced amount of acetylcholine being released in response to stimulation of the nerve. (From Adams et al., Principles of Neurology, 6th ed, pp 1471)
The specialized postsynaptic region of a muscle cell. The motor endplate is immediately across the synaptic cleft from the presynaptic axon terminal. Among its anatomical specializations are junctional folds which harbor a high density of cholinergic receptors.
Contractile tissue that produces movement in animals.
Neurotoxic proteins from the venom of the banded or Formosan krait (Bungarus multicinctus, an elapid snake). alpha-Bungarotoxin blocks nicotinic acetylcholine receptors and has been used to isolate and study them; beta- and gamma-bungarotoxins act presynaptically causing acetylcholine release and depletion. Both alpha and beta forms have been characterized, the alpha being similar to the large, long or Type II neurotoxins from other elapid venoms.

Conditions characterized by impaired transmission of impulses at the NEUROMUSCULAR JUNCTION. This may result from disorders that affect receptor function, pre- or postsynaptic membrane function, or ACETYLCHOLINESTERASE activity. The majority of diseases in this category are associated with autoimmune, toxic, or inherited conditions.

The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B.
An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur. (Adams et al., Principles of Neurology, 6th ed, p903)
Autoantibodies directed against various nuclear antigens including DNA, RNA, histones, acidic nuclear proteins, or complexes of these molecular elements.

Mechanical devices used to produce or assist pulmonary ventilation.
A medical specialty concerned with the study of the structures, functions, and diseases of the nervous system.
A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys, and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.

TE671 cell-based ELISA for anti-acetylcholine receptor antibody determination in myasthenia gravis. (1/830)

BACKGROUND: Acetylcholine receptor (AChR) from human muscles is the antigen used currently in radioimmunoprecipitation assays (RIPAs) for the determination of anti-AChR antibodies in the diagnosis of myasthenia gravis (MG). Our aim was to develop and validate an ELISA using TE671 cells as the source of AChR. METHODS: After TE671 cell homogenization, the crude AChR extract was used for plate coating. Anti-AChR antibodies were determined in 207 MG patients and in 77 controls. RESULTS: The mean intra- and interassay CVs (for two samples with different anti-AChR antibody concentrations) were 9.7% and 15.7%, respectively. Test sensitivity and specificity, for generalized MG, were 79.5% (95% confidence interval, 72.8-85.0%) and 96.1% (89.0-99.1%). The detection limit was 2 nmol/L. Anti-AChR antibody concentrations from 53 MG patients, as tested with our ELISA, showed good agreement with an RIPA with a mean difference (SD) of 1.0 (5.6) nmol/L. CONCLUSION: Our ELISA is a simple screening test for the diagnosis of MG and enables rapid and inexpensive patient follow-up.  (+info)

Myasthenia gravis and polymyositis as manifestations of chronic graft-versus-host-disease. (2/830)

Myasthenia gravis and polymyositis are each a rare manifestation of immune dysregulation in chronic graft-versus-host disease (cGVHD). We report a 4-year-old boy with idiopathic acquired aplastic anemia who developed myasthenia gravis 22 months and polymyositis 69 months after an allogeneic BMT (5/6 matched, MLC-nonreactive). The occurrence of both syndromes in one patient is unique. Autoimmune dysfunction may be associated with the development of cGVHD as demonstrated by the high incidence of prior aplastic anemia in BMT patients presenting with myasthenia gravis and polymyositis. Recognition of these neurologic manifestations is important in the diagnosis and treatment of cGVHD.  (+info)

Experimental autoimmune myasthenia gravis and CD5+ B-lymphocyte expression. (3/830)

Myasthenia gravis is one of the typical organ specific autoimmune disease and the CD5+ B-lymphocytes are known to be associated with the secretion of autoimmune antibodies. The authors performed the study to establish an animal model of experimental autoimmune myasthenia gravis (EAMG) by immunizing the nicotinic acetylcholine receptor (AChR) and to understand CD5+ B-lymphocyte changes in peripheral blood of EAMGs. Lewis rats weighing 150-200 g were injected subcutaneously three times with 50 microg AChR purified from the electric organ of Torpedo marmorata and Freund's adjuvant. The EAMG induction was assessed by evaluating clinical manifestations. The CD5+ B-lymphocyte was double stained using monoclonal PE conjugated anti-CD5+ and FITC conjugated anti-rat CD45R antibodies and calculated using a fluorescence-activated cell sorter (FACS). In three out of ten Lewis rats injected with purified AChR, the EAMG models were established. The animals showed definite clinical weakness responded to neostigmine; they had difficulty in climbing the slope, or easily fell down from a vertical cage. The range of CD5+ B-lymphocytes of peripheral blood in the EAMG models was 10.2%-17.5%, which was higher than in controls. In conclusion, the EAMG models were successfully established and the CD5+ B-lymphocyte expression in peripheral blood increased in EAMGs. This provided indirect evidence of the autoimmune pathomechanism of human myasthenia gravis.  (+info)

Congenital myasthenia gravis: clinical and HLA studies in two brothers. (4/830)

Two brothers with congenital myasthenia gravis are described. In both, ptosis and ophthalmoplegia responded poorly to oral anticholinesterase therapy and to thymectomy. The brothers had two different HLA haplotypes and neither had the HLA-A1-B8-DW3 haplotypes which are commonly associated with myathenia gravis in adult-onset cases.  (+info)

The value of thymectomy in myasthenia gravis: a computer-assisted matched study. (5/830)

In the absence of a prospective randomized study of patients treated conservatively or with thymectomy, a computer-assisted retrospective matches study was devised. Of 563 patients treated for myasthenia gravis without thymoma up to 1965, 104 had thymectomy. With computer assistance, each surgical patient was matched with a medical patient on the basis of age, sex, and severity and duration of disease. On this basis 80 of the 104 surgical patients could be matched satisfactorily. There were 16 males and 64 females in each of the matched surgically treated and medical control groups. A complete remission was experienced by 27 of the 78 patients in the surgical group as compared to 6 of the medical group. Improvement was noted by 26 of 78 surgically treated patients and 13 of 78 receiving medical treatment. Survival for patients having thymectomy. Thirty-four patients in the medical group had died as compared to 11 in the surgical group. Comparison of survival in relation to sex, duration of symptoms, or age (less than 30 or less than 30 years) did not show a significant difference. Until more effective treatment is available for myasthenia gravis, thymectomy deserves consideration for both sexes, and with increased age or long duration of symptoms.  (+info)

Mice with IFN-gamma receptor deficiency are less susceptible to experimental autoimmune myasthenia gravis. (6/830)

IFN-gamma can either adversely or beneficially affect certain experimental autoimmune diseases. To study the role of IFN-gamma in the autoantibody-mediated experimental autoimmune myasthenia gravis (EAMG), an animal model of myasthenia gravis in humans, IFN-gammaR-deficient (IFN-gammaR-/-) mutant C57BL/6 mice and congenic wild-type mice were immunized with Torpedo acetylcholine receptor (AChR) plus CFA. IFN-gammaR-/- mice exhibited significantly lower incidence and severity of muscle weakness, lower anti-AChR IgG Ab levels, and lower Ab affinity to AChR compared with wild-type mice. Passive transfer of serum from IFN-gammaR-/- mice induced less muscular weakness compared with serum from wild-type mice. In contrast, numbers of lymph node cells secreting IFN-gamma and of those expressing IFN-gamma mRNA were strongly augmented in the IFN-gammaR-/- mice, reflecting a failure of negative feedback circuits. Cytokine studies by in situ hybridization revealed lower levels of lymphoid cells expressing AChR-reactive IL-1beta and TNF-alpha mRNA in AChR + CFA-immunized IFN-gammaR-/- mice compared with wild-type mice. No differences were found for AChR-reactive cells expressing IL-4, IL-10, or TGF-beta mRNA. These results indicate that IFN-gamma promotes systemic humoral responses in EAMG by up-regulating the production and the affinity of anti-AChR autoantibodies, thereby contributing to susceptibility to EAMG in C57BL/6-type mice.  (+info)

Scanning a DRB3*0101 (DR52a)-restricted epitope cross-presented by DR3: overlapping natural and artificial determinants in the human acetylcholine receptor. (7/830)

A recurring epitope in the human acetylcholine receptor (AChR) alpha subunit (alpha146-160) is presented to specific T cells from myasthenia gravis patients by HLA-DRB3*0101-"DR52a"-or by DR4. Here we first map residues critical for DR52a in this epitope by serial Ala substitution. For two somewhat similar T cells, this confirms the recently deduced importance of hydrophobic "anchor" residues at peptide p1 and p9; also of Asp at p4, which complements this allele's distinctive Arg74 in DRbeta. Surprisingly, despite the 9 sequence differences in DRbeta between DR52a and DR3, merely reducing the bulk of the peptide's p1 anchor residue (Trp149-->Phe) allowed maximal cross-presentation to both T cells by DR3 (which has Val86 instead of Gly). The shared K71G73R74N77 motif in the alpha helices of DR52a and DR3 thus outweighs the five differences in the floor of the peptide-binding groove. A second issue is that T cells selected in vitro with synthetic AChR peptides rarely respond to longer Ag preparations, whereas those raised with recombinant subunits consistently recognize epitopes processed naturally even from whole AChR. Here we compared one T cell of each kind, which both respond to many overlapping alpha140-160 region peptides (in proliferation assays). Even though both use Vbeta2 to recognize peptides bound to the same HLA-DR52a in the same register, the peptide-selected line nevertheless proved to depend on a recurring synthetic artifact-a widely underestimated problem. Unlike these contaminant-responsive T cells, those that are truly specific for natural AChR epitopes appear less heterogeneous and therefore more suitable targets for selective immunotherapy.  (+info)

Detection of antibodies directed against the cytoplasmic region of the human acetylcholine receptor in sera from myasthenia gravis patients. (8/830)

The nicotinic acetylcholine receptor (AChR) is the autoantigen in the human autoimmune disease myasthenia gravis (MG). Anti-AChR antibodies in MG sera bind mainly to conformational epitopes, therefore the determination of their specificities requires the use of native AChR. Antibody competition studies suggest that most MG antibodies are directed against the extracellular part of the molecule, whereas antibodies directed against the cytoplasmic region of the AChR have not been detected. To determine whether even small quantities of such antibodies exist in MG sera, we performed competition experiments based on the inhibition by MG sera of the binding of MoAbs to the human AChR, rather than inhibition by MoAbs of the binding of MG sera performed earlier. When MoAbs directed against cytoplasmic epitopes on the alpha or beta subunits (alpha 373-380 and beta 354-360) were used as test MoAbs, 17% or 9% of MG sera inhibited the binding of the anti-alpha or anti-beta subunit MoAbs, respectively, by > or = 50%. Non-specific inhibition was excluded. These results suggest the presence, in several MG sera, of antibodies directed against cytoplasmic regions of the AChR; yet these antibodies seemed to represent a relatively small proportion of the total anti-AChR antibodies. The corresponding epitopes may be involved in the inducing mechanisms in certain MG cases, and knowledge of the presence of such antibodies may be useful in understanding the autoimmune mechanism involved in MG.  (+info)

N2 - Autoantibodies to acetylcholine receptors (AChR) are demonstrable in approximately 90% of patients with acquired myasthenia gravis (MG) and are the major pathogenic cause of the defect in neuromuscular transmission that is characteristic of MG. Experimental autoimmune myasthenia gravis (EAMG) can be induced in animals by immunization with AChR and adjuvants. Induction of EAMG and of autoantibodies to AChR is T cell dependent. Studies in congenic mice revealed that susceptibility to EAMG is linked to the major histocompatibility complex. The lymphocyte proliferative response to AChR is controlled in congenic mice by gene(s) within the 1-A subregion. In this communication we present evidence that proliferation of ...
Pregnant women with Myasthenia gravis often have more weakness and fatigue because of the added weight and effort of pregnancy. Some pregnancy complications may be more likely in women with Myasthenia gravis. Preterm labor (labor before 37 weeks of pregnancy) is more likely. It is thought that anticholinesterase medications used to treat MG may cause uterine contractions. Myasthenic crisis may be more likely during the stress of labor.. Delivery of the baby may be more difficult in women with Myasthenia gravis. While labor itself is not affected by Myasthenia gravis (the uterus is a smooth muscle), the muscles needed for pushing can be affected. This may make forceps and vacuum-assisted deliveries more likely.. A medication called magnesium sulfate that is commonly used for treating high blood pressure and preterm labor should not be used in women with Myasthenia gravis. This drug blocks the nerve-muscle connections and can worsen Myasthenia gravis muscle weakness.. Between 12 and 20 percent of ...
Graves disease and myasthenia gravis are both auto-immune diseases and the coexistence of these two diseases is rare but well recognized. Myasthenia gravis is more frequent in patients with thyroid disease. Here we present a case of 28-year-old male patient having Auto-immune thyroid disease (Graves disease) with concomitant myasthenia gravis. In conclusion, we report that the coexistence of Myasthenia Gravis with Autoimmune thyroid disease might have prognostic relevance and occurs in a subgroup of myasthenia gravis patients with a mild form of the disease.

Myasthenia gravis is a chronic autoimmune neuromuscular disease characterized by varying degrees of weakness of the skeletal (voluntary) muscles of the body. Symptoms vary in type and intensity. The hallmark of myasthenia gravis is muscle weakness that increases during periods of activity and improves after periods of rest. Muscles that control eye and eyelid movements, facial expression, chewing, talking, and swallowing are often, but not always, involved. The muscles that control breathing and neck and limb movements may also be affected. Myasthenia gravis is caused by a defect in the transmission of nerve impulses to muscles. Normally when impulses travel down the nerve, the nerve endings release a neurotransmitter substance called acetylcholine. In myasthenia gravis, antibodies produced by the bodys own immune system block, alter, or destroy the receptors for acetylcholine. The first noticeable symptoms of myasthenia gravis may be weakness of the eye muscles, difficulty in swallowing, or ...
Myasthenia gravis is a disease of the motor nervous system. It doesnt affect your dogs sensory nerves, but it can severely limit his mobility and other physical functions, like swallowing. In a normal dogs nervous system, the nerve endings secrete the neurotransmitter known as acetylcholine, which carries messages from one nerve ending to another and tell the dogs muscles to move. When canine myasthenia gravis occurs, the number of nerve receptors for acetylcholine in your dogs brain diminishes, leaving your dog susceptible to muscle weakness. There are two common types of myasthenia gravis. Congenital myasthenia gravis is hereditary, and occurs when a dog is born without the appropriate number of acetylcholine receptors in his brain. Acquired canine myasthenia gravis is a type of autoimmune disorder that attacks and damages aceltycholine receptors. ...
Myasthenia gravis in one member each of two sets of twins is described. A 17 year old girl developed generalized myasthenia gravis at the age of 14 years, while her monozygotic twin sister has remained in good health during a three year period of observation. Another patient was a 19 year old woman with the onset of generalized myasthenia gravis at the age of 11 years, and her dizygotic twin sister has been in good health.. Myasthenia gravis has been described in 13 sets of monozygotic twins, seven sets of dizygotic twins, and one set of twins with undetermined zygosity. Both members of twins were affected in five sets of monozygotic twins and one set of twins with undetermined zygosity, and only one twin was affected in the remaining sets of twins. Occurrence of myasthenia gravis in both members of monozygotic twins and in none of dizygotic twins, and frequent familial occurrence of the disease suggest the role of a genetic factor in the pathogenesis of this disease.. ...
Familial Autoimmune Myasthenia Gravis (FAMG) is rarely reported.

AU - Nichelli, Paolo F.. PY - 2018/6/1. Y1 - 2018/6/1. N2 - An unsolved issue remains whether there are clinical and immunological features to predict in a single patient the risk of conversion from ocular Myasthenia Gravis (OMG) to generalized disease (GMG) as 50-60% of patients may progress within 1-2 years since onset. Anti-acetylcholine receptor antibodies (AChR Abs) are found in up to 50% of OMG patients; muscle-specific tyrosine kinase antibodies (MuSK-Abs) are present in about 70% of the whole seronegative (SN), who usually develop a severe disease with bulbar involvement. We surveyed a cohort of 175 OMG patients with purely ocular symptoms and we compare the outcome of patients with antibodies to AChR or to MuSK with those seronegative for both Abs (DSN). All patients had purely ocular signs ...
ICD-9 Code: 358.0.. ICD-10 Code: G70.0. Definition: Myasthenia gravis is an autoimmune disorder of the neuromuscular junction. It is characterized clinically by muscle weakness and immunologically by autoantibodies directed against the postsynaptic acetylcholine receptor. These autoantibodies are pathogenic, causing increased turnover and decreased surface expression of the acetylcholine receptor, which results in decreased muscle depolarization and weakness.. Etiology: Although most cases of myasthenia gravis are idiopathic, some patients have associated thymomas or thymic hyperplasia. Myasthenia gravis may also occur as a rare reaction to D-penicillamine therapy.. Demographics: Myasthenia gravis is rare, with a prevalence of approximately 14 per 100,000, and has a bimodal distribution. There is a slight female predominance among patients with disease onset in the second and third decades, and a male predominance among patients older than 50 years of age. There is a genetic predisposition, ...
Both myasthenia gravis and graves disease are auto-immune diseases. Patients with myasthenia gravis may have evidence of coexisting auto-immune thyroid diseases like graves disease. The coexistence of two diseases is rarely observed but easily recognized if the association comes to mind. In this report, we present a case of 17-year-old female patient having myasthenia gravis with concomitant graves disease and is treated successfully with both pyridostigmine and propylthiouracil options. In conclusion, our case is a good example that the clinical features of autoimmune diseases can overlap and the presence of one auto-immune disease in a patient should require detailed investigations for other autoimmune diseases..

We reported an 81-year-old woman with metastatic melanoma, in whom myasthenia gravis and rhabdomyolysis developed after nivolumab monotherapy. The first symptom of myasthenia gravis was dyspnea. Ultrasonography detected hypokinesis of the bilateral diaphragm suggesting myasthenia gravis, although there was no abnormal finding of the lungs in computed tomography images. Acetylcholine receptor binding antibodies were low-titer positive in the preserved serum before administration of nivolumab, strongly suggesting that the myasthenia gravis was a nivolumab-related immune adverse event. Despite the remarkable clinical benefits of immune checkpoint inhibitors for patients with advanced melanoma, it is important to recognize unexpected immune-related adverse events.. ...
Myasthenia Gravis and Pregnancy What is myasthenia gravis? Click Image to Enlarge Myasthenia gravis (MG) is a complex autoimmune disorder in which antibodies destroy neuromuscular connections. This results in muscle weakness and fatigue. The Myasthenia Gravis Foundation estimates the incidence of MG in the United States to be about 20 out of 100,000 and occurs in women more often than men. The degree of muscle weakness depends on the severity of the disease. Weakness occurs in the muscles under voluntar...

Bethesda, Maryland-(ENEWSPF)-August 11, 2016. In a global study of myasthenia gravis, an autoimmune disease that causes muscle weakness and fatigue, researchers found that surgical removal of an organ called the thymus reduced patients weakness, and their need for immunosuppressive drugs. The study, published in the New England Journal of Medicine, was partially funded by the National Institutes of Health.. Our results support the idea that thymectomy is a valid treatment option for a major form of myasthenia gravis, said Gil Wolfe, M.D., Professor and Irvin and Rosemary Smith Chair of Neurology, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo, New York, and a leader of the study.. The Thymectomy Trial in Non-Thymomatous Myasthenia Gravis Patients Receiving Prednisone (MGTX) was a randomized, controlled study conducted on 126 patients aged 18-65 between 2006 and 2012. The researchers compared the combination of surgery and immunosuppression with the drug prednisone ...

Myasthenia gravis is a neuromuscular disorder. Neuromuscular disorders involve the muscles and the nerves that control them. Myasthenia gravis is a type of autoimmune disorders. An autoimmune disorder occurs when the immune system mistakenly attacks healthy tissue. In people with myasthemia gravis, the body produces antibodies that block the muscle cells from receiving neurotransmitters from the nerve cell. Symptoms: Myasthenia gravis causes weakness of the voluntary muscles.

Myasthenia gravis (MG) is mediated by autoantibodies to the acetylcholine receptor (AChR), expressed in muscle and rare thymic myoid cells. Most early-onset cases show thymic lymph node-type infiltrates, including pre-activated plasma cells spontaneously producing anti-AChR antibodies. Since these are not evident in the associated thymomas found in another 10% of MG patients, AChR-specific B cells must be autosensitized elsewhere. Unexpectedly, at diagnosis, |70% of MG/thymoma patients also have high-titer neutralizing autoantibodies to IFN-alpha, and |50% to IL-12; moreover, titers increase strikingly if the thymomas recur, indicating a closer tumor relationship than for anti-AChR. To investigate this, we have measured autoantibody production by cells cultured from thymomas, any available thymic remnants and blood, with or without the B cell stimulant pokeweed mitogen (PWM). To check autoantibody specificity and clonal origins, we isolated Fabs from two combinatorial libraries from producer thymus
BUFFALO, N.Y. -- A new study in the New England Journal of Medicine addresses a question doctors have sought to clarify for decades: whether a surgery conducted since the 1940s benefits the patients it targets.. The study to be published August 11 (available online on August 10 at 5 p.m.) found that surgical removal of the thymus gland from patients with myasthenia gravis, a rare autoimmune disease that affects neuromuscular function, provides significant benefit in patients who do not have a chest tumor.. Myasthenia gravis (MG) results from an immune-mediated disruption of communication between nerve and muscle - the neuromuscular junction. Symptoms may include droopy eyelids; blurred or double vision; difficulty speaking, swallowing and breathing; and muscle weakness. Some patients develop thymoma, a benign tumor of the thymus gland. The disease affects as many as 60,000 Americans and its incidence has been increasing, in part as a result of improved diagnostic techniques and an aging ...
A patient was initially diagnosed with right basal ganglia lymphoma causing left hemiparesis. His disease was resistant to intravenous methotrexate, so he received radiation therapy with remarkable regression of the mass. However, 6 months after his initial diagnosis, he developed symmetric weakness of the proximal muscles. Electromyography was consistent with myasthenia gravis and anti-acetylcholine receptor antibodies were elevated. Treatment with pyridostigmine and corticosteroids improved his symptoms. The residual lymphoma was further treated with rituximab and temozolomide with complete resolution. Pyridostigmine and corticosteroids were stopped after 14 months of initiation with good results. Our case is the first case report of paraneoplastic myasthenia gravis developing in a patient with primary CNS lymphoma. The diagnosis of paraneoplastic myasthenia should be considered in patients with CNS lymphoma who develop muscle weakness and speech problems. © 2010 The Japanese Society of ...
Myasthenia gravis is disease that causes weakness in the muscles under your control. It happens because of a problem in communication between your nerves and muscles. Myasthenia gravis is an autoimmune disease. Your bodys own immune system makes antibodies that block or change some of the nerve signals to your muscles. This makes your muscles weaker. Common symptoms are trouble with eye and eyelid movement, facial expression and swallowing. But it can also affect other muscles. The weakness gets worse with activity, and better with rest. There are medicines to help improve nerve-to-muscle messages and make muscles stronger. With treatment, the muscle weakness often gets much better. Other drugs keep your body from making so many abnormal antibodies. There are also treatments which filter abnormal antibodies from the blood or add healthy antibodies from donated blood. Sometimes surgery to take out the thymus gland helps. For some people, myasthenia gravis can go into remission and they do not ...
The telltale symptom of myasthenia gravis is noticeable muscle weakness. This weakness, in cases that are severe enough to prompt those experiencing it to seek medical advice, usually sets in too rapidly to be considered a natural part of the aging process. Those suffering from the early stages of myasthenia gravis will generally experience rapid fatigue, particularly in the arms and legs. The weakness of the legs will often lead to difficulty in walking for any length of time. As the disease progresses, facial muscles will become involved. The lack of ability to control these muscles leads to some of the most noticeable symptoms of myasthenia gravis, which include drooping eyelids and an inability to control the muscles around the mouth. Associated symptoms of the loss of facial muscle strength include a loss of control of the muscles of the throat and eyes, which cause difficulty in swallowing and an inability to focus the eyes, respectively. In a minority of cases, symptoms are limited to ...

Myasthenia gravis, like all chronic diseases, may have psychiatric consequences ie: psychiatric morbidity usually appears as anxiety disorder, such as panic disorder and generalized anxiety disorder, and as depressive disorder. Objective: to determine the prevalence of depression among Sudanese patients with myasthenia gravis seen in Elshaab Teaching Hospital. Methodology: This is a descriptive prospective, hospital based, cross sectional study. It was conducted in al Shaab Teaching Hospital. Almost 33 patients with myasthenia gravis, referred or admitted to Al Shaab Hospital in the period from January 2009 to September 2009, were included in the study. Full detailed history & clinical examinations were performed for each patient in addition to list of investigations included Tensilon test, x.ray & CT. Chest. Depressive symptoms were evaluated using DSM1V-TR criteria. Results: we found that 45% of our patients had an evidence of depression, 30% of them had major depression, & 15% had minor ...
Introduction Epidemiological studies conducted in several countries have shown that the incidence of myasthenia gravis is on the increase. This is more so in the older (,50 years) population. The reasons for this increase have not been fully explained even after correcting for an ageing population and improved diagnosis. We were interested in establishing if there were different clinical and immunological features accounting for this apparent changing incidence between young and late onset myasthenia gravis. Methods and results: We have prospectively recruited 123 patients in the first 22 months of our study. So far, our data indicate that 76.27% of all newly diagnosed myasthenia patients in our region are over the age of 50 years. Around 73.5% of patients had ocular symptoms at onset and 38.5% had pure ocular myasthenia. Ptosis was the most common first symptom, followed in decreasing order of frequency by diplopia, limb weakness, dysphagia, dysarthria, difficulty with chewing and head drop. ...

AU - Aarli, Johan A.. PY - 2001/1/10. Y1 - 2001/1/10. N2 - Similar to human autoimmune myasthenia gravis (MG), canine MG occurs spontaneously and is associated with autoantibodies against the nicotinic acetylcholine receptor (AChR). In addition to AChR, human MG patients with thymoma or late-onset MG have antibodies against titin and ryanodine receptor (RyR). The objective of this study was to establish if dogs with confirmed MG (AChR antibody titer ,0.6nmol/l) also developed titin and RyR antibodies and identify possible associations with thymoma, late age of onset, or severity of clinical signs. Sera from dogs (n=430) with previously diagnosed autoimmune MG (N=415), other immune-mediated neuromuscular disorders including polymyositis (PM) and masticatory muscle myositis (N=5), and control dogs (N=10) were evaluated ...
Susceptibility to experimental autoimmune myasthenia gravis (EAMG), which is induced in mice by injection of purified Torpedo nicotinic acetylcholine receptor (TAChR), is influenced by the I-A locus products, which restrict presentation of AChR Th epitopes. The bm12 mutation of the I-Ab molecule in the C57BL/6 strain, which is highly susceptible to EAMG, yields the EAMG resistant mutant B6.C-H-2bm12 (bm12). We investigated here the consequences of the bm 12 mutation on the CD4+ response to the TAChR alpha subunit. Upon immunization with TAChR, CD4+ cells became sensitized to TAChR and anti-AChR antibodies were produced in both bm12 and C57BL/6 strains. Overlapping synthetic peptides, corresponding to the complete sequence of TAChR alpha subunit, were used to identify Th epitopes. CD4+ cells from C57BL/6 mice recognized peptides T alpha 150-169, T alpha 181-200, and T alpha 360-378. CD4+ cells from bm12 mice did not respond to any synthetic sequence. Upon injection of the three C57BL/6 Th epitope ...
Myasthenia gravis (MG) is a long-term neuromuscular disease that leads to varying degrees of skeletal muscle weakness.[1] The most commonly affected muscles are those of the eyes, face, and swallowing.[1] It can result in double vision, drooping eyelids, trouble talking, and trouble walking.[1] Onset can be sudden.[1] Those affected often have a large thymus or develop a thymoma.[1]. Myasthenia gravis is an autoimmune disease which results from antibodies that block or destroy nicotinic acetylcholine receptors (AChR) at the junction between the nerve and muscle.[1] This prevents nerve impulses from triggering muscle contractions.[1] Most cases are due to immunoglobulin G1 (IgG1) and IgG3 antibodies that attack AChR in the postsynaptic membrane, causing complement-mediated damage and muscle weakness.[5] Rarely, an inherited genetic defect in the neuromuscular junction results in a similar condition known as congenital myasthenia.[6][7] Babies of mothers with myasthenia may have symptoms during ...

Also, epidemiologic studies demonstrate an MHC linkage of myasthenia gravis in the man. In order to obtain direct experimental evidence for the influence of the genes of the MHC complex in the development of myasthenia gravis, we used mice transgenic to individual HLA molecules. We observed an increased susceptibility to the disease in HLA DQ8 transgenic mice compared to HLA DQ6 transgenic mice (J. Immunol. 160:4169; 1998). These mice lacked endogenous mouse class II molecules. In the present study we mapped the cryptic and dominant sequences ...
Generalized fatigue in myasthenia gravis results in a sedentary lifestyle and profound physical deconditioning, leading to reduced fitness and increased risk of obesity, hypertension, dyslipidemia, and type 2 diabetes. This study will characterize the activity and fitness levels and cardiovascular disease risk profile in 30 chronic, generalized myasthenic subjects. Hypotheses are that a) subjects with myasthenia gravis are physically inactive with reduced fitness level and high incidence of obesity and poor cardiovascular disease risk profile, and b) a 3 month multi-modal home exercise program that includes aerobic, resistive, and pulmonary training components will improve physical activity, strength, fitness, dyspnea, body composition and reduce cardiovascular disease risk. Specific aims are to a) define the baseline physical activity and fitness levels and prevalence of insulin resistance and dyslipidemia in stable sedentary myasthenic subjects, b) determine whether a 3 month moderate ...
The main symptom of myasthenia gravis is weak muscles. Muscles get weaker with activity and better with rest. Affected muscles are usually in the eyes, face, jaw, neck, arms and legs, and muscles used to breathe. People also get very tired. Pregnant women with myasthenia gravis often have more weakness and are more tired. This is because of the added weight and effort of pregnancy. Some women who get very weak and tired may have a myasthenic crisis. Their breathing muscles cant work properly, and they have respiratory failure. The main symptom of myasthenic crisis is more problems with breathing. You may be more likely to have a myasthenic crisis when you are in labor ...

The increasing demand on diagnostic assays that are sensitive and specific for pathogenic antibodies, and the interest in identifying new antigens, prompted the development of cell-based assays for the detection of autoantibodies in myasthenia gravis and other autoimmune disorders. Cell-based assays were initially used to show that clustering the AChR improved the positivity in myasthenia gravis, and similar assays have now been applied to detection of antibodies to neuromuscular junction candidate proteins such as LRP4 and agrin. In addition cell-based assays have been used in the routine detection of antibodies to proteins expressed on the surface of neurons (NMDAR, LGI1, CASPR2, AMPAR, GABA-A/B, GlyR, and DPPX) and glia (AQP4, MOG). Here, we summarize the findings in myasthenia and discuss the advantages, disadvantages and controversial issues of using cell-based assays in the detection of these antibodies, and their relevance to the testing of preclinical models of disease.

Ocular myasthenia: Find the most comprehensive real-world symptom and treatment data on ocular myasthenia at PatientsLikeMe. 47 patients with ocular myasthenia experience fatigue, depressed mood, pain, anxious mood, and insomnia and use Azathioprine, Cyclosporine, Methotrexate, Prednisone, and Pyridostigmine to treat their ocular myasthenia and its symptoms.
The purpose of this trial is to determine if thymectomy combined with prednisone therapy is more beneficial in treating non-thymomatous myasthenia gravis than prednisone therapy alone.
Twenty patients with myasthenia gravis had chest radiography, conventional tomography, and computed tomography (CT) of the thorax within 1 month of thymectomy. Four of the six macroscopic tumors were detected on routine chest radiography; conventional tomography provided no additional information. CT detected all six macroscopic tumors and provided additional information that was not available by other procedures. However, 18 patients (90%) had anterior mediastinum densities on CT, which could not be distinguished preoperatively from thymic tumors. All six patients with macroscopic tumors had serum antistriational muscle antibody titers; this test was negative in 10 of 11 patients (91%) without thymoma. Chest radiography, CT of the thorax, and antistriational antibodies are the tests recommended for detection of a thymoma in patients with myasthenia gravis.. ...

Most individuals with myasthenia gravis (MG) have no family history of MG and the disorder appears to occur spontaneously (sporadically) for unknown reasons. However, 3-5 percent of patients may have family members with MG or other autoimmune disorders. Individuals with MG have an increased frequency of certain genetically determined human leukocyte antigens (HLAs), suggesting that genetic predisposition may play some role. (HLAs are proteins that play an important role in the bodys immune system; they influence the outcome of transplantation and appear to affect an individuals predisposition to certain diseases.) Other autoimmune diseases also appear to occur with increased frequency in individuals with MG, including thyroid disorders and systemic lupus erythematosus. These observations suggest that there is some genetic predisposition to MG which requires a trigger from the environment to cause the disease.. Myasthenia gravis is caused by an abnormal immune reaction (antibody-mediated ...

TY - JOUR. T1 - Transient neonatal myasthenia gravis. AU - Papazian, O.. PY - 1992/1/1. Y1 - 1992/1/1. N2 - Transient neonatal myasthenia gravis is a postsynaptic neuromuscular transmission defect occurring in 21% of infants born to women with active (and, less commonly, in remission) acquired myasthenia gravis. Although passive-transfer acetylcholine receptor (AChR) antibodies are found in the majority of these newborns, their pathogenic role is questionable because only some infants are symptomatic. Pathogenesis in infants without AChR antibodies is unknown. There is still no biologic marker for prenatal identification of this subpopulation of newborns, although HLA typing may be a promising tool. Sucking, swallowing, and respiratory difficulties are the most common presenting signs in the first day of life. Final diagnosis is done when administration of acetylcholinesterase agents transiently corrects the neuromuscular transmission defect. Serum AChR antibody titers follow the same pattern as ...

The association of thymoma with myasthenia gravis is well established (1). We describe a patient in whom thymoma and myasthenia gravis occurred together with relapsing polychondritis. This is the first association of relapsing polychondritis with thymoma, myasthenia gravis, or both.. A 64-year-old white man was hospitalized in December 1985 with a 9-month history of generalized weakness, severest in his shoulders and neck muscles, associated with ptosis, and difficulty in chewing and swallowing. All symptoms progressively worsened and partially subsided with rest. Four months earlier, pain and redness of his nose and right ear had occurred for 1 week, and cleared ...
Myasthenia gravis is a rare autoimmune disorder of the neuromuscular junction characterized by varying degrees of weakness of the voluntary muscles.… Myasthenia Gravis (Neuromuscular Junction Disease): Read more about Symptoms, Diagnosis, Treatment, Complications, Causes and Prognosis.
The neuromuscular junction represents a synapse between the motor nerve terminal and the surface of the muscle fiber, but the synaptic and postsynaptic elements are somewhat different from those in a central synapse. The neuromuscular junction is vulnerable to a variety of disease largely because it has no blood-brain barrier and is accessible to circulating factors. Poisoning by environmental insecticides or self-administered insecticides are common, and there are varieties of plant extracts that interfere with neuromuscular transmission. One of the most common disorders is caused by autoantibodies, to molecules on the postsynaptic membrane that cause autoimmune myasthenia gravis (MG). This chapter concentrates on the mechanisms at the neuromuscular junctions, which lead to various autoimmune disorders like MG. There are now four well-defined disorders in which autoantibodies are thought to be pathogenic, namely MG, muscle-specific kinase antibody-Associated MG, Lambert-Eaton myasthenic syndrome, and
Myasthenia gravis (MG) and the Lambert-Eaton myasthenic syndrome (LEMS) are the prototypical autoimmune channelopathies of the peripheral nervous system. The predominant neuromuscular junction antigenic targets are either postsynaptic (MG; nicotinic acetylcholine receptor (AChR)) or presynaptic (LEMS; voltage-gated calcium channels (VGCCs)). Over the last 35 years the development of active immunization, passive transfer models, and use of transgenic animals has greatly enhanced our understanding of the biology of these disorders. The search for other antibodies in previously seronegative MG cases has led to the recognition of antibodies against clustered AChRs, muscle-specific kinase (MuSK) and low density lipoprotein receptor-related protein 4 (Lrp4). The pathogenic mechanisms that underlie these newer serological subclasses of MG are not yet fully understood, but are likely to be different from AChR antibody-mediated disease. While many still would consider MG an antibody-mediated disorder, it is
Pregnant women with MG often have more weakness and fatigue because of the added weight and effort of pregnancy. Some pregnancy complications may be more likely in women with MG. Preterm labor (labor before 37 weeks of pregnancy) is more likely. It is thought that anticholinesterase medications used to treat MG may cause uterine contractions. Myasthenic crisis may be more likely during the stress of labor.. Delivery of the baby may be more difficult in women with MG. While labor itself is not affected by MG (the uterus is a smooth muscle), the muscles needed for pushing can be affected. This may make forceps and vacuum-assisted deliveries more likely.. A medication called magnesium sulfate that is commonly used for treating high blood pressure and preterm labor should not be used in women with MG. This drug blocks the nerve-muscle connections and can worsen MG muscle weakness.. Between 12 and 20 percent of babies born to women with MG may have neonatal myasthenia gravis. This occurs when ...
Introduction: Viruses are commonly cited as triggers for autoimmune disease. It is unclear if West Nile virus (WNV) initiates autoimmunity. Methods: We describe 6 cases of myasthenia gravis (MG) that developed several months after WNV infection. All patients had serologically confirmed WNV neuroinvasive disease. None had evidence of MG before WNV. Results: All patients had stable neurological deficits when they developed new symptoms of MG 3 to 7 months after WNV infection. However, residual deficits from WNV confounded or delayed MG diagnosis. All patients had elevated acetylcholine receptor (AChR) antibodies, and 1 had thymoma. Treatment varied, but 4 patients required acetylcholinesterase inhibitors, multiple immunosuppressive drugs, and intravenous immune globulin or plasmapheresis for recurrent MG crises. Conclusions: The pathogenic mechanism of MG following WNV remains uncertain. We hypothesize that WNV-triggered autoimmunity breaks immunological self-tolerance to initiate MG, possibly ...
Myasthenia Gravis (MG) is a chronic autoimmune neuromuscular disorder that causes voluntary muscle weakness. There is a listing for MG. However, like many listings, the Social Security Administration (SSA) rewrote the MG listing to make it more difficult to meet. I represent a 51 year old former owner of an auto repair business whose application for Social Security Disability (SSD) benefits was approved in only four months without providing a listing opinion from the treating neurologist. However, I provided the SSA with hundreds of pages of treatment records that noted visual and speech difficulties, weakness and fatigue. As MG is relatively rare, many SSA analysts are unfamiliar with it, which makes the approval in only four months somewhat unexpected. It appears that the claimant had his claim reviewed by someone who performed their job properly, rather than automatically denying something they did not understand. Previous Next ...

NINDS : 51 All forms of myasthenia are due to problems in the communication between nerve cells and muscles. Most involve the activities of neurotransmitters. Neurotransmitters are chemicals that allow neurons to relay information from one cell to the next. For neurotransmitters to be effective, the nerve cell must release the neurotransmitter properly, and the muscle cell must be able to detect the neurotransmitter and respond to its signal properly. The most common type of myasthenia, myasthenia gravis, is caused by an abnormal immune response in which antibodies block the ability of the muscle to detect the neurotransmitter. Congenital myasthenia, however, differs from myasthenia gravis because the disrupted communication isnt caused by antibodies, but by genetic defects. There are several different subtypes of congenital myasthenia, each the result of a specific genetic mutation. Since all types of myasthenia are due to the inability of nerves to trigger muscle activity, they all involve ...
The current edition begins with an overview of the anatomy and molecular architecture of the neuromuscular junction and the electrophysiologic diagnosis of its disorders. The introductory chapters are followed by a detailed exposition of the pathogenesis, natural history, diagnosis and therapy of the autoimmune myasthenias, the Lambert-Eaton myasthenic syndrome, and the increasingly complex and fascinating diseases collectively referred to as congenital myasthenic syndromes. The acetylcholine receptor is a major target of both autoimmune and inherited myasthenias and a separate chapter reviews its structural and functional properties. The book also describes disorders that often target terminal nerve segment near the neuromuscular junction-- the syndrome of peripheral nerve hyperexcitability and the Guillain-Barré syndrome.. ...

PY - 2001/3/1. Y1 - 2001/3/1. N2 - The cellular mechanisms of high dose systemic acetylcholine receptor (AChR) T cell epitope, α146-162 peptide-induced tolerance in experimental myasthenia gravis were examined. CD4 cells are the prime target for α146-162 peptide-induced tolerance. The expression of CD69, Fas, and B7.2 molecules on AChR-immune lymphocytes was enhanced within 4-12 h after tolerance induction. A high dose of α146-162 peptide in IFA failed to suppress T cell proliferation and/or clinical myasthenia gravis in lpr and gld mice deficient in Fas and Fas ligand, respectively. A high dose of α146-162 peptide in IFA in AChR-immunized mice induced apoptosis of BV6 cells. Further, reconstitution of IL-2 in vitro-recovered α146-162 peptide tolerized T cell proliferation, IFN-γ, and IL-10 ...

Lambert-Eaton syndrome (or LEMS for Lambert-Eaton myasthenic syndrome) has similar effects to myasthenia gravis, and is likewise an autoimmune disease. In cases of Lambert-Eaton syndrome, antibodies against voltage-dependent calcium channels are formed in the area of the presynaptic membrane, which significantly impairs transmission of nerve signals to the muscles..

PURPOSE: To establish non-radioactive assays for detection of antibodies (Abs) to the acetylcholine receptor (AChR) and to muscle specific kinase (MuSK). To show that the assays can be used in Tianjin for testing patients with MG. METHOD: AChR and MuSK Abs in 51 Chinese MG patients sera were tested in Oxford, UK, using the conventional radioimmunoprecipitation assay (RIPA), a recently described cell-based assay (CBA), and a new non-radioactive fluorescence immunoprecipitation assay (FIPA) which can measure both AChR and MuSK antibodies in one step. 102 MG sera were subsequently tested by CBA and FIPA in Tianjin, China. Based on the different serological subgroups, the clinical features of these 153 MG patients were analyzed. RESULTS: We first confirmed the sensitivity and specificity of the assays in Oxford. There was good agreement between the FIPA and the RIPA for AChR Abs (r² = 0.6; p | 0.0001) with 80% positivity in the RIPA and 76% in the FIPA. Two patients were positive for MuSK Abs (4% of total
Results: Between 4/06 and 8/07, 13 patients underwent thymectomy for MG. Three patients had open, transsternal thymectomies via median sternotomy during this period. One patient was approached primarily via a median sternotomy due to a BMI of 40. The remaing 12 patients were positioned supine with a shoulder role and the table planed ~45 degrees; left side up. In 2 morbidly obese patients (BMIs 36.7 and 37.2), both with asthma, a thoracoscope was introduced initially into the left hemithorax. However, due to their inability to tolerate one-lung ventilation, the left VATS approach was aborted and a sternotomy was performed without repositioning. Ten patients (median BMI 32.5) underwent a succesful robotic thymectomy via a left VATS approach with complete excision of the mediastinal fat pad and entire thymus. No patient required perioperative blood transfusion or emergent conversion to open procedure for bleeding. There were no post-operative complications in either group. Median LOS was 3 days ...

With the support of the CTSA, Gil I. Wolfe, MD, the top winner, has been nominated by UB to be considered for a prestigious Top 10 Clinical Research Achievement Award, a signature program of the Clinical Research Forum, which takes place in Washington, D.C., in April.. Wolfe, Irvin and Rosemary Smith professor and chair of the Department of Neurology, won the award for his work on Randomized Trial of Thymectomy in Myasthenia Gravis, published in the New England Journal of Medicine.. For over a half-century, thymectomy, the surgical removal of the thymus gland, has been a mainstay in the treatment of myasthenia gravis, a rare autoimmune disease that affects neuromuscular function. However, the evidence for its benefits has been inconclusive.. In a multicenter international randomized trial comparing thymectomy plus prednisone with prednisone alone, Wolfe and co-authors found that thymectomy does provide significant benefit in patients. ...

An individuals major histocompatibility complex (MHC) ancestral haplotype (AH) is the dearest single determinant of susceptibility to MHC associated immunopathological disease, as it defines the alleles carried at all loci in the MHC. However, the direct effects of any of the 150-200 genes that constitute the MHC are difficult to determine since recombination only occurs at defined hotspots. This review concerns the 8.1 AH (HLA-A1, C7, B8, C4AQ0, C4B1, DR3, DQ2), which is carried by most Caucasians with HLA-B8. It is associated with accelerated human immunodeficiency virus (HIV) disease, and susceptibility to insulin-dependent diabetes mellitns (IDDM), systemic lupus erythematosus, dermatitis herpetiformis, common variable immunodeficiency and IgA deficiency, myasthenia gravis and several other conditions. We have mapped susceptibility genes for HIV, IDDM and myasthenia gravis co the central MHC between HLA-B and the tumour necrosis factor or complement genes. Here we consider which of the ...

The mechanism of action of pyridostigmine is characterised by the increased concentration of acetylcholine in the synaptic clefts through reversible inhibition of cholinesterase activity, thus enhancing parasympathetic tone. Although pyridostigmine has been used extensively by patients with myasthenia gravis to counteract skeletal muscle weakness, its cardiovascular action has been considered a side effect.6. The systematic study of its haemodynamic effects has shown that pyridostigmine decreases resting7,15 and exercise heart rate10 and reduces QTc dispersion15 in healthy people without impairing exercise tolerance.10 When administered at eight hour intervals, pyridostigmine elicited sustained 24 hour bradycardia and augmented heart rate variability.8 All of these effects were obtained without impairment of systolic or diastolic cardiac functions.16 In addition, a single 45 mg dose of pyridostigmine blunted the double product increase during mental stress when given orally to healthy people.9 ...
Through the use of sophisticated apheresis machines, the transfusion specialists separate patient blood into its cellular and liquid fractions and, depending on the particular disease process, cleanse an individuals blood of either harmful cellular material or soluble plasma factors. For example, by removing plasma (plasmapheresis) the Apheresis Unit treats a large number of antibody-mediated autoimmune diseases such as myasthenia gravis (a neurological disorder), Goodpastures syndrome (a kidney disorder), and TTP/HUS (a clotting disorder often associated with viral infection or the ingestion of bacterially contaminated food).. Other procedures include removing elevated levels of white cells (leukapheresis) to prevent the neurological and pulmonary damage resulting from impeded blood flow that can be experienced by newly diagnosed leukemic patients (hyperleukocytic syndrome) or removing and exchanging red blood cells for fresh banked cells (erythrocytapheresis) to prevent or treat the ...
