Chronic Inflammatory Demyelinating Polyneuropathy is an autoimmune disease with progressive and relapsing courses. The main clinical presentations are diffuse deep tendon hyporeflexia or areflexia and symmetric proximal-distal muscles weakness. Myasthenia gravis is also an immune mediated disease with fluctuating ocular and bulbar symptoms and sometimes weakness. Although both myasthenia gravis...

Autoimmune myasthenia gravis is a T-cell-dependent, antibody-mediated, rare neuromuscular disorder. Interleukin-4, acting via interleukin-4 receptor alpha, plays a pivotal role in B-cell differentiation and antibody production and has been implicated to influence disease progression in experimental autoimmune myasthenia gravis. Polymorphisms of the interleukin-4 receptor alpha gene have been sh...

In 52 patients with myasthenia gravis serum myoglobin showed a significant inverse correlation to circulating thyroxine and triiodothyronine levels. The highest myoglobin concentration (240 ng/ml) was found in a myasthenia gravis patient with hypothyroidism. Slightly elevated myoglobin (54-60 ng/ml) was measured in four euthyroid myasthenic patients. The data suggest that a concomitant hypothyr...

The role of genetic factors in the causation of myasthenia gravis is not clear. Oppenheim, as early as 1900, reported familial instances of myasthenia and suggested that genetic factors were involved. On the other hand, Ford in 1937 stated, 'there is never any familial or hereditary tendency in myasthenia gravis'. However, since then, there have been several reports of familial instances of mya...

BACKGROUND Myasthenia gravis is an autoimmune neuromuscular disorder characterized by the production of abnormal autoantibodies directed against the receptors present in the neuromuscular junction. It has been the standard practice to offer thymectomy in all generalized myasthenia gravis patients despite the lack of robust evidence. OBJECTIVES The objectives of this study are to describe the ...

The ampicillin group of antibiotics has among been considered to be amongst the safest for use in patient with Myasthenia gravis, although a report in 1971 suggested that such might not be the case. A recent report suggested that ampidillin may aggravate Myasthenia gravis in patients and experimental animals. We report a case of clinically controlled Myasthenia gravis, in whom the administratio...

A male patient with muscle weakness had clinical findings of ptosis, diplopia, proximal leg weakness, and positive repetitive nerve stimulation (RNS) test. He demonstrated positive acetylcholine receptor antibody. This lung cancer patient was presenting myasthenia gravis. The causal association between non-small-cell lung cancer and non-thymomatous myasthenia gravis has not been clarified yet. ...

Patients with generalized myasthenia gravis (MG) often have associated ventilatory muscle involvement. It is not known whether patients with isolated ocular muscle involvement have identifiable involvement of their ventilatory muscles. Most studies have assessed muscle involvement by measuring muscle strength; however, we hypothesized that measures of ventilatory muscle endurance may be more se...

BACKGROUND The myasthenia gravis is twice as common in women as in men and frequently affects young women in the second and third decades of life, overlapping with the childbearing years. Generally, during pregnancy in one third of patients the disease exacerbates, whereas in two thirds it remains clinically unchanged. Complete remission can occur in some patients. METHODS To describe the cli...

Four families each with two patients with autoimmune myasthenia gravis or related conditions are reported. All clinical forms of myasthenia gravis were represented and different disease types were found within the same family. Either one or two generations could be affected and no association with a single HLA haplotype was found. The frequency of familial autoimmune myasthenia gravis is very l...
