Ambigous Issues hard to summarize in subject line!

1) Does anyone know of any information (either acecdotal or research)about taking half doses of BOTH Asacol and Azulfidine (i.e., 3 tabs Asacol in AM and 2 tabs Azulfidine in PM each day)?  I seem to get good results and I can find no published risks or contraindications about this.

2) I am being followed both locally and at the Mayo Clinic for lung infiltrates seen on CT scans. The scans are ambiguous, with even some improvement seen between scans. I have had a normal bronchoscopy with no cultures found.  I have no breathing symptoms that I know of.  Since I had been on Remicade, because of the possibility it had contributed to the infiltrates, I am not getting the infusions.  One of my Pulmonologists strongly leans toward an open lung biopsy (partly because my Gastroenterologist understandably needs an okay on the lungs in order to proceed) and the other Pulmonologist leans toward waiting for future scans show improvement. My Crohn's status is marginal through all of this.

Any help or referral would be appreciated. //
