Myasthenia Gravis Support Group
Myasthenia gravis (MG) is a neuromuscular disease leading to fluctuating muscle weakness and fatiguability. The hallmark of myasthenia gravis is muscle weakness that increases during periods of activity and improves after periods of rest. Although myasthenia gravis may affect any voluntary muscle, muscles that control eye and eyelid movement, facial expression, and...

The Conference was taped and will be available (?Georgia MGFA site). Dr. Kaminski could not be there due to the hurricane and having to make up patient cancellations. But Dr. Cutter filled in well. About half the participants were seronegative, which would come as no surprise to us. Dr. Cutter made it clear in talking about the registry that seronegative MGers would not be excluded, not only so far as the registry was concerned, but in future studies; although there may be closer scrutiny as to diagnosis.
My discussion with him (off camera) regarding the reporting of statistics in the journals and literature was encouraging. He knew statistics were not being properly reported, but did not seem to realize the impact upon diagnosis and treatment. He seemed more willing to make an issue of the problem. Being a well known biostatistician, he should have more clout!
(For those who missed the prior discussion here, the difference between 80% of people with MG and 80% of people diagnosed with MG is very important and the strange logic of skilled practitioners doing SFEMGs and finding abnormalities in 99% and then saying from those findings that not having an abnormal SFEMG in a weak muscle ruled out MG which is bad enough for us, but is translated by many doctors into not having an abnormal SFEMG rules out MG no matter the skill of the technician or preparation of the patient, or choice of muscle. Even in that study, those skilled in this difficult test missed 1%. One in a hundred missed is not at all acceptable in medicine.)
Dr. Cutter talked about biomarkers which shorten and support research and help with funding. There are no good biomarkers in MG. That is to say no biological blood tests or findings that predict or determine severity or remission or cure. There are not many good biomarkers out there, but there is more money for research for specific illnesses, especially heart disease and cancer. He spoke of the registry of people with MS which is in service and on which the MG registry will be based. Many of the problems of privacy and access have already been considered there and safeguards implemented.
They are closing recruitment for the thymectomy trial and will then make the data coming from that trial available to researchers, although the actual publishing of the data is about five years away.
Let me say that this is a difficult trial for researchers due to the vagaries of MG, not to mention there can be no blinding as to patients, (no surgery that does not take out the thymus, but just opens the chest). It will be a help for our decisions, even if there are legitimate objections to the findings.
TJ will be happy to know that Dr. Hafer-Macko, presenting the exercise study, believes in sarcopenia in aging adults (which I don't and won't until they study Europeans or other older adults with active life styles. I will concede maybe some muscle loss after 80 (-: ). Her finding was that there was improvement in reserve for activities of daily living in participants in the study, but most importantly that there was no increase of disability with a gradual increase in exercise in those with MG who were STABLE FOR THREE MONTHS before entering the study. She did discourage the kind of exercise that they were doing-- treadmill, bands, etc.--until patients were stable. (My two cents, in agreement, is there is no need to incur a good reason for bodily fatigue, until you know what the monster can throw at you.)

Lunch provided was very good. There were more sweets than Dr. Hafer-Macko might approve, but apparently were approved by the participants! I think that those of us for whom the desire was not only to hear the speakers but to see, hug, and converse with those we meet here on a daily basis would not have been TOO disappointed if none of the speakers had shown! I had a wonderful time. My trip over the mountains was especially beautiful and, although long, added to the enjoyment of those days. b.

Conference sounded exciting and this is phenomenal information!

Way to keep those docs thinking about the seronegs!

I had some great interaction with Dr. Porter at the MA/NH MGFA meeting and am now directly in contact with him. I also have some podcasts of his to post, which I think I will add to my thread under his name.
Many hugs and many thanks!!!

20 years ago or so I participated in a study of muscle building for folks over 40 vs those in their 20's at Mayo. The exercise was a daily hour on an exercise bicycle under supervision with increasing levels of effort for 12 weeks and the control the same person (me included) avoiding exercise for 12 weeks. Each study required you hold your weight exactly even during the whole time by diet adjustment under a dietitian's guidance.
The results showed that for younger folks, muscles were built by the aerobic exercise. For the older folks, no real increase in muscles occurred with this type of active exercise, and some loss did occur with doing nothing. Each study part included pre-post muscle biopsies and other measurements including body efficiency.
The conclusion of this very large study was that to build muscles when you are young is quite easy including aerobically, to do it when you are older does not work with aerobic exercise. Of course aerobic exercise was good for cardiovascular and other improvements.
Anerobic exercise (weight lifting...). did work with older folks and also drugs like testoterone which do work to add muscles at any age.
I have been relatively inactive for almost 3 years due to an severe leg/knee injury and a series of surgeries followed by MG this spring. I have noticed muscle loss. I wonder if some anerobic exercise might be reasonable while MG is still limiting for aerobic exercise.
Of course, maybe I will just send for some Internet testosterone and take the easy way ;-) Supposed to perk a fellow up too.
Im glad to hear the report of open mindedness in gathering and reporting more accurate info on sero negs. If these things could get into the literature we could at least hand these to the docs as a "lagit" references.
Ill listen to the video when it's up on the site.

PS...I forgot to mention that we also met Kerry Bunn at the meeting!

I may run this past my neuro.

You are right. MG is like a foreign country. But none of us is a native and we all are learning the language and the customs in order to survive. However the people here are friendly and questions get answered. A dictionary would be helpful, but then it's usually provided online. However a good start for MG and this report would be:
seronegative is someone whose blood tests do not show the expected antibodies to the muscle receptors (that does not mean they do not have them).
biomarker is some bodily sign (usually a blood test) that is useful in determining presence or absence of disease or change in symptoms
EMGs are muscle tests SFEMG is the single fiber muscle test that some neurologists rely on to decide whether or not someone has MG
sarcopenia is muscle loss due solely to aging
registry is a data collection of information about a particular group, in our case people with MG
The way studies are done and statistics are reported has an effect on the people who have MG and people who are seronegative have particular problems since they are the ones most often left out of the statistics and they often go undiagnosed for long periods of time.
