Well your CD57 dropped - it is supposed to go up when you're getting better. BUT, many LLMD's find that test to not be a reliable predictor of healing...
Honestly ? After hearing Dr. H talking about
the horrific herxes people on dapsone have, that do not herx on something else.... i think this CD57 is a VERY RELIABLE tool to measure how many persisters u have in your body. Each persister produces some chemicals that interfere with CD57 cells production, which render u immuno supressed. The more persisters u have the less your CD57. At some point your body stops fighting the infection altogether and your antibodies stop being produced, hence all these people with false negative, that are the sickest of all .... People never get well with low CD57, they just get into remission and relapse later, if they are lucky years later if not, immediately.
CD57 is believed to be unreliable because patients "get healed" even if CD57 is low. Now we know all this is hogwash , nobody really gets healed if chronic, and these CD57 studies are from the time the medical community was still in denial about
lyme persisters, before the groundbraking papers by K. Lewis and Zhang about
persisters, which are too important researchers to be ignored.
I wonder what does CD57 do on people treated with Dapsone for 6 months or so ... that have horrific herxes, does it go up ? Anyone here on dapsone for months that still tracks CD57 ? Would be really interesting study to make...Yes, honestly. Many LLMD's don't use the test.
LLMD MR says this (this is not verbatim): CD57 is a specific type of WBC. Other things can cause it besides lyme.
It can go up and down through treatment. Two studies were presented at the ILADS conference...showing that the CD57 doesn't always increase at the end of treatment. Originally, it was thought that the level could be followed throughout treatment, and improvement means we're on the right track.
LLMD MR occasionally uses it - when he is looking for 1 more piece to diagnose a patient. If a person has symptoms, but negative WB, and a low cd57...it is a CLUE they may have LD.
