Chronic Fatigue And Myasthenia Gravis

How Does Myasthenia Gravis Affect The Nervous System

Normally nerves send a signal to muscles using a chemical called acetylcholine, which tells the muscles when to move. In patients with myasthenia gravis, the bodys immune system mistakenly interferes with the muscles receptors for acetylcholine. When these receptors cannot work properly, the affected muscles tire easily.

Viral And Other Infections

Post-viral fatigue syndrome or post-viral syndrome describes a type of chronic fatigue syndrome that occurs following a viral infection. A recent review found Epstein-Barr virus antibody activity to be higher in patients with CFS, and that a subset of patients with CFS were likely to have increased EBV activity compared to controls. Viral infection is a significant risk factor for CFS, with one study finding 22% of people with EBV experience fatigue six months later, and 9% having strictly defined CFS. A systematic review found that fatigue severity was the main predictor of prognosis in CFS, and did not identify psychological factors linked to prognosis.

Another review found that risk factors for developing CFS after mononucleosis, dengue fever, or Q-fever included longer bed-rest during the illness, poorer pre-illness physical fitness, attributing symptoms to physical illness, belief that a long recovery time is needed, as well as pre-infection distress and fatigue. The same review found biological factors such as CD4 and CD8 activation and liver inflammation are predictors of sub-acute fatigue but not CFS. However, these findings are not generally accepted due to the use of the Oxford criteria in selecting patients. The CDC does not recognize attribution of symptoms as a risk factor.

Memes About Myasthenia Gravis Awareness

Maybe its asking for too much for friends, family, doctors to be aware of myasthenia gravis. I mean it is a rare disease. But there are some very credible resources out here and were all doing our part to spread awareness about myasthenia gravis.

Its not a lack of access. We all have the internet. Often times I feel its a lack of interest.

People just dont care enough to be informed because it doesnt impact them or their loved ones.

Im thankful for the people in my circle who try to learn about what Im going through.

Try as they might they still may never understand what its like to have MG.

If you dont care enough to learn the details about someones chronic illness, thats fine. Live your truth. But please take this one piece of advice:

NEVER say you dont look sick to someone with a chronic illness!

Thats the ultimate slap in the face and it may get you slapped in the face .

Memes are a way to embody sentiments perfectly. I saw myself relating to these memes about myasthenia gravis but I believe people with other chronic illnesses can relate to them as well.

Which meme did you relate to most?

How Is It Treated

It is not known exactly what causes fatigue in people with MG, but the studies mentioned above give us important clues. The most important clue is that people in remission from MG or who have few symptoms are less likely to feel fatigued.

This decrease in fatigue leads researchers to believe that fatigue can be treated, similar to other MG symptoms. In fact, in many of these studies, after treatment controlled MG symptoms, fatigue improved.1-4

While there are no therapies approved specifically to treat fatigue in MG, people with MG have recommended self-care practices. This includes getting plenty of rest, exercising, or getting therapy.

Because fatigue is a common symptom of MG that is related to worse MG symptoms and lower quality of life, it is important that your doctor is aware of it and helps you find treatments that work for you.4

How Common Is It

Studies show that fatigue is extremely common in MG. Up to 82 percent of people studied reported that they regularly feel fatigued. Half of these people felt this fatigue in their mind as well as their body.1,2,4

People with generalized MG were more likely to experience fatigue than people whose MG is restricted to the muscles around the eye.1,2,4

Fatigue has been found to be more common in women with MG. However, one of the most important findings is that the more severe your MG is, the more likely you are to experience fatigue.1-4

How Is Myasthenia Gravis Diagnosed

Your doctor can diagnose myasthenia gravis based on your symptoms and certain tests. During the physical exam, your doctor will ask about your medical history and symptoms.

A common way to diagnose myasthenia gravis is to test how you respond to certain medicines. Muscle weakness often dramatically improves for a brief time when you are given an anticholinesterase medicine. If you respond to the medicine, it confirms myasthenia gravis.

Other tests that may be done include:

• Blood tests. These tests look for antibodies that may be present in people with myasthenia gravis.

• Genetic tests. These tests are done to check for conditions that run in families.

• Nerve conduction studies. A test called repetitive nerve stimulation is used to diagnose myasthenia gravis.

• Electromyogram . A test that measures the electrical activity of a muscle. An EMG can detect abnormal electrical muscle activity due to diseases and neuromuscular conditions.

Does Myasthenia Gravis Cause Fatigue

Myasthenia gravis is a chronic autoimmune disease that reduces the muscle strength and the ability for the muscles to engage in repetitive muscle movements, these occur due to a problem in the neuromuscular junction.

Fatigue is extreme tiredness, lack of energy, and difficulty in concentrating in spite of adequate rest and nutrition. Muscle fatigability is difficulty in initiation of muscle movement and/or sustaining that muscle movement. Fatigue is a very subjective feeling there is no proper definition or parameter to identify the severity of it. Fatigue depends on certain physical and psychological factors therefore, it is difficult to get an objective idea about fatigue when a patient complains of it. Fatigue can be either physical fatigue or mental fatigue or both. Chronic fatigue is the presence of fatigue above a certain limit for 6 months or more.

Myasthenia Gravis Treatment And Home Remedies

Your treatment will depend on your age, how severe your symptoms are, and how fast the condition is progressing. You might need one or several treatments together. Your doctor may recommend a medication such as:

• Cholinesterase inhibitors. These medications boost the communication between your nerves and your muscles. They can help strengthen muscles.
• Corticosteroids. Corticosteroids such as prednisone mute your immune system and slow the release of antibodies that could be helping block your nerve receptors.
• Immunosuppressants. Your doctor may add immunosuppressants to your corticosteroids to help reduce your immune system response.
• Neonatal Fc receptor blocker. It works by blocking the autoantibodies that cause myasthenia gravis and helps ease the symptoms.

If youâre dealing with a sudden worsening of symptoms or will soon have surgery or other therapies, your doctor may recommend intravenous therapy. Choices for this include:

If your myasthenia gravis is due to a tumor on your thymus gland, you may need surgery to remove the whole gland . Even if you donât have a tumor, taking your thymus out may help ease your symptoms. It may take years to see benefits from a thymectomy.

You may need open surgery to remove your thymus. A surgeon opens your breastbone to get to your thymus and take it out.

Another option that may work is minimally invasive surgery. There are two options:

What Is Myasthenia Gravis Symptoms Causes Diagnosis Treatment And Prevention

Myasthenia gravis is a chronic autoimmune neuromuscular condition that causes muscle weakness and severe fatigue.

The term myasthenia gravis is Latin and Greek in origin, and means âgrave muscle weakness.â

The condition primarily affects the skeletal muscles, or the muscles attached to bones and responsible for skeletal movement.

As many as 60,000 Americans are living with the condition, the Myasthenia Gravis Foundation of America says, but the disease often goes undiagnosed.

Currently, theres no cure for myasthenia gravis. However, available treatments usually can control symptoms, allowing those diagnosed with the condition to lead relatively normal lives.

In addition, most people with myasthenia gravis have a normal life expectancy.

What Organs Does Myasthenia Gravis Affect

Myasthenia Gravis

• Myasthenia gravis is a chronic autoimmune disorder in which antibodies destroy the communication between nerves and muscle, resulting in weakness of the skeletal muscles.
• Myasthenia gravis affects the voluntary muscles of the body, especially those that control the eyes, mouth, throat and limbs.

Q Three Years Ago I Was Diagnosed

Q. Three years ago, I was diagnosed with chronic fatigue syndrome, and three months ago, I started to have vision problems. Thanks to a smart new doctor, we found the real problem was myasthenia gravis. Please tell your readers with chronic fatigue syndrome and fibromyalgia that it’s OK to ask for acetylcholine receptor antibodies.

A. I’m sorry to hear that you have one or both of the diseases you mentioned. They are very puzzling and difficult diseases with which to cope.

I think it’s OK for people to ask for this test, or any other test for that matter, especially when the symptoms indicate a reasonable possibility of the test results being useful.

You were fortunate to have a knowledgeable doctor because myasthenia gravis and chronic fatigue syndrome may have many symptoms that overlap with each other and other medical conditions.

Symptoms of myasthenia gravis include a drooping eyelid, double vision, difficulty in chewing and swallowing, trouble breathing, limb weakness, or a combination of these problems.

These are all caused by muscle weakness, which in turn is caused by a blocked signal at the junction between the nerves and muscles. It’s like trying to open a door with a key when another key has broken off inside the lock.

An antibody made by the immune system, presumably to fight off an earlier infection, is the broken key. A specific blood test can identify this antibody.

How Is Yale Medicine’s Approach To Myasthenia Gravis Unique

Clinicians at Yale Medicine are determined to find the right treatment for each individual. The Myasthenia Gravis Clinic emphasizes precision medicine, or customized treatment determined by each patients specific symptoms and medical history. The risks and benefits of each therapeutic option is carefully considered and discussed with each patient. The clinic is also designated by the Myasthenia Gravis Foundation of America as a national “Partner in MG Care” site.

Patients at the clinic have the option of enrolling in clinical trials of new, not-yet-approved therapies and other advanced diagnostics.

Genetic Predisposition To Ebv Infection

The diversity of human leukocyte antigen molecules results from selective pressure during co-evolution with pathogens . A characteristic of HLA diversity is the long-term persistence of allelic lineages, which causes trans-species polymorphisms to be shared among closely related species . In humans, there are 13 allelic lineages of DRB1 and, according to the phylogenetic relationship between the different DRB genes of primates described by Bontrop et al, the DRB1*04, *03 and *02 lineages are the oldest, with the DRB1*04 lineage being the most ancestral . Since EBV is the only human-adapted member of the genus Lymphocryptovirus, transferred to a hominid ancestor , it could be hypothesized that immune evasion mechanisms of the EBV have more effectively evolved among older allelic lineages of DRB1. Such an hypothesis could help explaining why individuals with haplotypes DR2-DQ6, DR3-DQ2 or DR4-DQ8 are less resistant to EBV infection and are at greater risk of developing EBV-related disorders .

Impact On Quality Of Life

People with MG who had high rates of fatigue were also found to have high rates of depression and lower quality of life. Quality of life means feeling comfortable, happy, and able to do the things that you like or need to do. Fatigue lowers quality of life, which lowers motivation to get things done.1,2

Fatigue can also make it harder for people to socialize. The result is higher levels of depression. The cycle does not end there: Higher rates of depression can mean less motivation to get physical exercise. This means that the muscles can lose strength, which is a big problem for those with MG.1-4

What Are The Treatment Options For Myasthenia Gravis

There is no one-size-fits-all approach to treating MG. It sometimes takes several months to find the best course of treatment. Patients will receive a personalized treatment regimen that may involve the following.

• Steroids: A class of drugs commonly used to treat autoimmune disease. But steroids are not necessarily a good long-term option. When taken for years, steroids can lead to other health problems, such as elevated blood pressure and increased risk of infection.
• Pyridostigmine: A synthetic drug that boosts the connection between muscle cells and nerve cells, leading to improved muscle strength and contraction. This drug is not considered a cure because if a patient stops taking it, muscle weakness will return.
• Immunosuppressants: A class of drugs that can suppress the bodys immune system, which helps lessen the symptoms of MG. These drugs include azathioprine and mycophenolate mofetil.
• Intravenous Immunoglobulin : A blood product that contains purified antibodies that have been isolated from donated blood.
• Plasmapheresis: A process during which a patients blood is filtered to remove the antibodies that interfere with the communication between nerve and muscle cells. When combined with oral medication, it can benefit patients with MG.
• Surgery: Patients who have a thymoma, or a noncancerous tumor on the thymus gland, will need to have the tumor surgically removed in a procedure called a thymectomy.

Therapeutic Options Against Ebv: Is There A Role In Me/cfs

Limited knowledge about the origin of ME/CFS has hampered the development of effective treatment. Current strategies include administering nutritional supplements to overcome deficiencies and symptomatic treatment with analgesics, steroids or antidepressants . Thus, if a putative association between EBV infection and the onset of ME/CFS exists, the development of biomarkers that could identify patients in whom this may occur, would create a window of opportunity for tailored treatment against EBV.

Figure 2 Schematic model of treatment with DNA demethylation agents followed by adoptive immunotherapy of EBV-specific T cells. Administration of low-dose DNA demethylation agents restores the expression of MHC class II molecules and induces expression of LMP1, EBNA-2 and EBNA-3C in EBV-latency I B cells, improving the recognition of these cells by EBV-specific T cells . EBNA-1-specific CD4 T cells can only recognize latent I cells exhibiting EBNA-1 in MHC class II molecules since EBNA-1 is poorly immunogenic. DNA demethylation agents induce lytic infection and apoptosis in EBV-transformed epithelial cells. Antiviral agents prevent viral replication.

Get Worse With Activity And Improve With Rest

Myasthenia gravis can affect any of the muscles that you control voluntarily. It can affect muscles of the face, hands, eyes, arms and legs and those muscles involved in chewing, swallowing and talking. Muscles that control breathing and neck movement also can be affected.

MG does not affect involuntary muscles such as the heart, smooth muscles of the gut, blood vessels, and uterus.

The hallmark of weakness related to MG is that is worsens with sustained activity of the involved muscle. Eye muscle weakness worsens with reading, and double vision may improve with a brief rest. When speech is affected, symptoms worsen with prolonged talking. Extremity weakness if often noticed when holding arms over the head. Drooping of the eyelids, neck weakness and other symptoms are usually worse at the end of the day.

A Mestinon Miracle: Vagus Nerve Stimulating Drug Helps Long Time Me/cfs Patient Exercise

by Cort Johnson | Jun 17, 2016 | Drugs, Homepage, Treatment |

Shes had chronic fatigue syndrome for twenty-eight years and has left no stone unturned in her attempts to get well. Shes traveled widely and seen some of the best ME/CFS doctors in the world. Despite being connected to the hilt in the ME/CFS, her results have been all too familiar her health has improved a bit but she, a former fitness buff, has never been able to exercise.

Shed had a really tough year. Multiple surgeries including a gall bladder removal, multiple emergency room visits and a mysterious drug reaction had laid her as low as she had ever been.

Many people might have given up after that but last year there she was in a pulmonary specialists office with a catheter in her arm working away on an exercise test.

There she was, almost 30 years later, doing an exercise test in an attempt to figure what had gone wrong.

Her goal to determine if the latest hot topic in ME/CFS mitochondrial issues were it for her. It turned out that they werent her mitochondria were working fine. Nor, despite the sarcoidosis she had, was her lung capacity diminished she still had the lungs of an athlete.

Mestinon turned out to be something of a miracle for her. She took too much at first and had some rather drastic side-effects but then ratcheted it down and then back up again.
