Stelara - Raised Liver Enzymes

Hi all, First post on the forum although I have been reading them for a while! I've been on Stelara for a couple of years and in the most recent routine bloods my liver enzyme was "slightly" raised. My biologics nurse didn't seem overly concerned about it and ran some more bloods a month later. In these bloods enzyme was still raised but had a gone down "slightly". She has asked me to go back in a month for more tests but hasn't advised if this is a common side effect etc. So, to my questions: Any Stelara users experienced this? Did you cease treatment? Were the medical profs equally as vaque? Any responses greatly appreciated! Thanks, Jamie
