Paulette, yes C. diff can be a form of pouchitis, but can colonize anywhere in the GI tract. Probably not the stomach though, because of the acid. As a matter of fact, chronic use of PPIs is a risk factor for C. diff, since lowering the acid levels makes the environment favorable to the bacteria.
Also, note that there are non-pathogenic strains of C. diff, and we are only concerned with those that make the toxins. Apparently, the strains that have developed that are resistant to fluoroquinolones (such as Cipro) tend to be more virulent, with more powerful toxins. That translates to more severe disease that is more difficult to treat.
Tim, I don't know if Dr. Shen specializes in C. diff, per se, but he runs the CC pouchitis clinic, so he probably sees more cases of any type of pouchitis. Plus, he gathers data for research. I believe the treatment is essentially the same, colon or not.
Part of the C. diff problem is that it is a spore former, making it capable of laying dormant for long periods, waiting for the ability to proliferate (like antibiotics changing the normal flora that keep it in check, low acid levels, or a suppressed immune system). So, recurrent and chronic cases are becoming more and more common. In those instances, learning how to keep it suppressed becomes the goal, not a cure.
I think this is something we all need to be vigilant about, not just those who have been diagnosed.
