John, I have been recently diagnosed with interstitial lung disease, after a lung biopsy they are calling it interstitial fibrosis. We know that I have had it for atleast a year if not 3. Presently, they are going to put me on Prednisone. It is suppose to strength my lungs. (steroid). I hope something works.. I haven't gotten much hope about this disease so far.. please write to me and I will answer anything I can for you.. Tell your brother good luck. Linda
