I personally believe there is a link there somewhere. We're now seeing class action suits related to IBS, Crohns, and the like - purported caused by Accutane. It seems only logical to me that if indeed the drug is related to those conditions, that flora imbalance was caused or exacerbated by the use of Accutane.
There is probably a better explanation, and I've got more ideas - but simply put, I indeed believe there is a connection.
