Hi Alexandria,   I'm not an expert on this issues, but in reading your comment I have a question.  Does your patient have a suprapubic catheter.  I ask because I've heard from other MS patients who finally had a SP catheter surgically placed, that they experienced much fewer UTIs.  Perhaps this is something to discuss with her doctors if she doesn't have one.   The pneumonia seems to be something which is more common in more advanced MS patients.  The inability to move around surely must increase the development of pneumonia.  Would that be correct?   In answer to your question - "are we looking at what happens more at the end of life with the frequency of these problems or is this just the progression of MS?"   I think that it could be some of both, but more so the MS.  Perhaps there are ways to eliminate the occurrence of infections, or at least try.  It's good to hear that she is responsive and interactive with those around her (talking and such).    Please tell her that someone out her on the internet wishes her well.
