Mycophenolate Mofetil (MMF) Efficacy in Glomerulonephritis (GN), a Retrospective Analysis

Mycophenolate Mofetil MMF has been widely used in post-transplant immunosuppression. Its role is emerging in GN. MMF demonstrated promising results compared with cyclosphosphamide in stage IV lupus nephritis, in a recently published trial. It has been found to have a wide safety profile, with mostly gastroinetestinal side effects, which can be avoided through titration. Its action is through inhibition of the enzyme IMDPH (ionosine monophosphate dehydrogenase), leading to purine antagonism and inhibition of lymphocytes. We were aiming to demonstrate the efficacy of MMF in our GN population. In this study, we reviewed 17 patients who received MMF (dose - 1 gm po bid) for the past year. They were only included if it was given for the management of resistant primary glomerulonephritis. Complete remission has been defined as proteinuria of less than 0.5 g/day and partial remission as a reduction of proteinuria 50% of starting MMF therapy; all 17 MMF therapy patients uniformly achieved good BP ((29%) achieved complete remission and this group consisted of 1 membranous GN, 2 lupus GN (type IV and membranous), one FSGS and one with MPGN. Four of 17 (23%) were non-responders to therapy. This group articles.aspx? id=41 to side effects. We conclude that the MMF appears to be an effective alternate treatment modality in resistant membranous GN, lupus nephritis (type IV and V) and possibly MPGN, and to a lesser extent in resistant FSGS. Further prospective data may demonstrate the efficacy of MMF in GN.
