In v3, I believe, regex is caseless - you don't have to
worry about case.

Hmm, using RegEx Test, hits were found in all of those
lines.

It is because * and - are word boundaries, I mentioned that
it is "difficult to do exactly what you want.
\*? is redundant if you're not going to use the result.
That is "*ist" be matched including it. "ist" will be
matched in "*ist" if you don't include it.
But the ending isn't included properly anyway. So simply
\bistd?\b
is probably good enough :-)
BTW, anyone trying this with a non-caseless implementation
should use:
(?s)\bistd?\b
