, I still have not voted but am going to give you the exact data and let you interpret it and I will vote accordingly.
On the Enterovirus Foundation website
, it states that for chronic enterovirus, titers of 1:320 and higher in the ARUP Lab micro-neutralization test are good indicators of current active infection. So that is what I am going by: if your titers are 1:320 or above, then you are elevated (active infection); otherwise you are low (inactive infection).
I am assuming (but I don't know for sure) that Dr Chia also uses this 1:320 threshold to signify a current active infection. He is on the board of the Enterovirus Foundation. Perhaps when you visit him in February, you might ask him what titer level he deems to be an active infection. I'd be very interested to know.
I will definitely ask him at my appt in Feb but until then, will tell you the titers. I was tested twice in early 2015 by ARUP and the titers flipped with each test but were never at 1:320 which you consider elevated or high.
First test 1/13/15: Coxsackie B 4: 1:40
First test 1/13/15: Echovirus 11: 1:160
Second test 2/24/15: Coxsackie B 4: 1:160
Second test 2/24/15: Echovirus 11: 1:80
I re-did the ARUP tests a few weeks ago for my upcoming consult with Dr. Chia but will not have the results until the appt. It is my first appt with him and I have not met him yet. I am very curious to see where the titers are now, approximately one year later.
If you had elevated titers at any point for coxsackievirus B, then please select the "elevated coxsackievirus B titers" options in your vote.
Since my highest titers for Coxsackie B4 & Echo 11 were 1:160 (never 1:320) then I assume you would not consider them to be high titers?
In the first post I explain this: my hunch is that crimson crescents may simply be a chronic version of herpangina. Coxsackievirus B can cause herpangina, but EBV cannot. That's why I was thinking that crimson crescents might only be found in coxsackievirus B-associated ME/CFS, but not in EBV-triggered ME/CFS.
I do have what looks like Crimson Crescents when I look in the mirror but I never had the herpangina that you posted. During mono/EBV, my tonsils were extremely enlarged and were almost touching each other and blocking off my air supply. At one point I got an abcess on my tonsil and part of it turned black and fell off (sorry to be gross.) I had to go to the ER twice during mono, I was so ill. Have had no throat issues since mono in 2012 (although the crimson crescents do appear to be there.)
My mom said that I had coxsackie virus as a baby so this may be why the titers are elevated but are not at 1:320? Will be telling all of this to Dr. Chia in Feb but am starting to think that all the viral titers are a red herring and not the cause of symptoms in my particular case (but of course I could be wrong.)
