rather than doing nothing, I think I would gently remove all the bad leaves, stems, etc & then take it out of the soil, wash off the roots & put it in clean room temp water. if you have a bit of african violet food put a small bit --say a very small pinch or less in said water and mix well. A very small bit goes a long ways, you do not want to over-feed.
IF the roots are bad just cut them off as well, if not leave them as is.
Hopefully this well work well for you. I have done it with many plants I was faced with losing. and "most" of the time it works.
