                        I'm sure the depression can be present due to many reasons.  It can also be the prednisone.  I have crohn's disease and several yrs ago was on as high as 240 mgm/day.  The emmotional "roller coaster" from the pred. is awful.  The drug does a great job but the side effects can be a real pain.  From my own experience, it does help to have much support when dealing with this roller coaster.  Good Luck - Hang in there.
