Not really. Baal curses you to lower your resists when you are fighting his minions, Quov Tsin uses mythal, which reduces your resists by 20 (i think), and possibly tal rasha and the mages at the binding of baal uberquest pierce your resists, but none of these are dangerous, aside from mythal at QT, but thats easily dodgeable, and you are usually stacking res anyways for that fight.
Then there is the 100% resist pierce modifier of tier 13(?) labs, but thats an another story
