Mycophenolate mofetil (MMF) in systemic sclerosis-associated interstitial lung disease (SSc-ILD) in Sclero Forums (MAIN) Posted July 30, 2010 This is interesting. I'd like to see them review more than 10 patients. I've been on cellcept for more than 3 years and after a year, my forced vital capacity (FVC)increased from 45 to 60 and has remained stable. My diffusing capacity (DLCO) was at 49 in March 07 and it has stayed between 45 and 50, so no significant increase. So my personal results seem to echo the results of this study. Everything has been stable for about 2 years now. I'll take it.
