The treatment of pneumonia in patients with myasthenia gravis is the same as that for typical pneumonia, using corresponding antibiotics for bacterial, viral, or other microbial infections. However, if a patient with myasthenia gravis has a concomitant lung infection, aminoglycoside antibiotics, which can exacerbate conditions affecting neuromuscular junctions, i.e., worsen myasthenia gravis, should not be used. Sedative drugs are also contraindicated, as well as any drugs that might intensify muscle weakness.

Can myasthenia gravis affecting respiration be cured?

Myasthenia gravis affecting respiration can be cured because myasthenia gravis can improve after treatments such as oral medication or plasmapheresis. Another possibility is myasthenia gravis concurrent with a myasthenic crisis, which has various forms, causing respiratory difficulties. At this point, symptomatic treatment is required, including the use of ventilators, intubation, and in severe cases, a tracheotomy. After the critical period on the ventilator passes, respiratory function can improve or the myasthenia can ameliorate.

Myasthenia gravis often co-occurs with which diseases?

Myasthenia gravis is a type of autoimmune disease of the nervous system, mainly caused by the production of abnormal antibodies in the body. These antibodies affect the acetylcholine receptors in the postsynaptic membrane, thereby impacting the transmission of nerve impulses at the neuromuscular junction. Being an autoimmune disease, myasthenia gravis usually coincides with the following conditions: The first major category is thymus diseases, with most patients experiencing thymic hyperplasia, and particularly, there may be cases of thymoma. If there is a thymoma, it is advised to undergo surgical treatment promptly. The second major category may involve hyperthyroidism, so it is essential to test thyroid function. Thirdly, some patients may also test positive for antinuclear antibodies, which requires careful differential diagnosis.

What medicine should be taken for myasthenia gravis?

Myasthenia gravis is a type of neurological immunological disease in neurology, mainly caused by a disorder of the body's own immune function. Patients in the body will produce antibodies against acetylcholine receptors, thus affecting the transmission of nerve impulses at the neuromuscular junction. For this disease, the following medications are generally prescribed: The first type of medication is a cholinesterase inhibitor, which can increase the amount of acetylcholine at the neuromuscular junction, thereby effectively improving clinical symptoms. The second type of medication is corticosteroids, because this disease is caused by an abnormal inflammatory response. Therefore, taking corticosteroids can suppress the inflammatory response. Treatment generally starts with a small dose and gradually increases, maintaining for a period before gradually tapering off. It may also be necessary to take other immunosuppressants. (Please take the medication under the guidance of a doctor)

Does myasthenia gravis cause sensitivity to cold?

Patients with myasthenia gravis tend to be sensitive to cold, mainly due to the following factors: Firstly, patients with myasthenia gravis generally experience overall weakness and have very limited physical activity, making their physique rather frail. Patients with a weak physique are definitely more susceptible to colder environments. Secondly, patients with myasthenia gravis have lower resistance to diseases and often take immunosuppressants for a long time, making them highly susceptible to respiratory and lung infections. In cold conditions, some viruses can exploit this weakness, leading to exacerbated lung and respiratory infections, which is another major reason why patients with myasthenia gravis are sensitive to cold. Thirdly, myasthenia gravis is an autoimmune disease that leads to immune dysfunction. This immune dysfunction makes patients particularly sensitive to cold stimuli. In a cold environment, their immune function may become even more disordered, contributing further to their sensitivity to cold.

Is it dangerous to have a fever with myasthenia gravis?

Myasthenia gravis is a disease of the neuromuscular junction, essentially an autoimmune inflammatory response that causes generalized weakness and fatigue of the skeletal muscles, with symptoms that are less severe in the morning and worsen by the evening, and fluctuate over time. The weakness can be alleviated by rest. When patients with myasthenia gravis develop a fever, it is generally considered to be caused by an infection, perhaps a viral infection such as an upper respiratory tract infection, which can also induce fever. In such cases, the main treatment involves drinking plenty of water and consuming fresh vegetables and fruits. If necessary, some antiviral medications and antipyretics may be administered. If the fever is due to a bacterial infection, symptomatic treatment should be accompanied by the appropriate antibiotics. However, the choice of antibiotics must be made with caution. Patients with myasthenia gravis should not use aminoglycosides or fluoroquinolones, as these could exacerbate their condition. Penicillins or cephalosporins may be used instead. (Please consult a professional physician for specific medication guidance.)
