We have a c30 year old patient who is a bodybuilder and eats large
supplements of creatine and high-protein preparations.
He has had a plasma CK activity up to 1800 u/L, when his plasma AST was
91 u/L, GGT 15 u/L, CK-MB 32 u/l (inhibition assay, not mass). Plasma
creatinine is about 100 micromol/L.
He denies im injections and there are no abscesses etc.
I would very much appreciate suggestions as to why his plasma CK
activity is so high:
... is there any known effect of eating creatine?
... due to muscle exertion (we see surprisingly high CK activity in
long-distance runners)
???
