Multifocal motor neuropathy (MMN) is an immune-mediated disorder characterized by slowly progressive asymmetrical limb weakness. Treatment with immunoglobulins (IVIg) leads to improvement of muscle strength. Anecdotal evidence suggests that immunosuppressive drugs as adjunctive therapy may be beneficial. Mycophenolate mofetil (MMF) is a potent and safe immunosuppressant. Safety and efficacy of MMF as adjunctive therapy for MMN patients receiving IVIg maintenance treatment were evaluated in a randomized controlled trial. MMN patients responding to IVIg treatment were eligible for randomization. Muscle strength and functional status were assessed at monthly intervals for 1 year. Three months after the start of MMF or placebo treatment, IVIg doses were reduced stepwise, until a deterioration of functioning or decline in muscle strength could be observed. An IVIg dose reduction of 50% during adjunctive treatment was defined as a primary endpoint. Secondary outcome measures were improvement in muscle strength and functional status after 3 months and reduction of anti GM1-IgM titres after 12 months of MMF treatment. Twenty-eight patients were randomized. One patient allocated to MMF reached the primary endpoint of 50% IVIg dose reduction. After 12 months IVIg reduction did not differ significantly between the two treatment groups. Patients did not experience drug toxicity and none of the patients showed significant disease progression after 12 months. Muscle strength and functional scores after 3 months and anti GM1-IgM titres after 12 months did not change. Adjunctive treatment of MMN patients with MMF at a dose of 1 g twice daily is safe but does not alter disease course or allow significant reduction of IVIg doses. Mycophenolate mofetil (MM) is an immunosuppressive agent developed and originally used to prevent acute rejection of solid-organ transplantation. There have been preliminary reports of its successful use in the treatment of autoimmune myasthenia gravis (MG). We conducted a double-blind, placebo-controlled pilot trial of MM in the treatment of suboptimally controlled, stable MG. Results of this pilot study are promising and suggestive of greater improvement in the patients who received MM compared to placebo. Our transplant centre began a prospective, randomized trial of steroid withdrawal in low risk renal transplant recipients on triple immunosuppression consisting of mycophenolate mofetil (MMF), microemulsion cyclosporine (CSA), and prednisone. One hundred and twenty patients were randomized either to discontinue or remain on steroids (60 patients per group). Study design consisted of analyses of 1-yr outcomes after study entry. This report includes the 1-yr results plus results at last follow-up (mean follow-up 3.7 yr). There were no significant differences in rates of patient and graft survival at 1 yr or at last follow-up. Additionally, the incidences of acute and chronic rejection as well as graft function were the same at 1 yr and at last follow-up. Significant improvement was noted in total serum cholesterol and bone density at 1 yr and last follow-up. Initial improvement in patient weight at 1 yr was not sustained at last follow-up. No significant impact of steroid withdrawal on serum triglycerides, blood pressure, or post-transplant diabetes mellitus was observed. To date, we have observed no immunologic risk, and some significant benefit in regards to side effects, of steroid withdrawal between 6 and 36 months after transplantation in low risk renal transplant recipients maintained on prednisone, MMF, and microemulsion CSA.
                Steroid withdrawal in low risk kidney transplant recipients is safe and ameliorates many of the unwanted sides effects of steroid use. The aim of the present study was to evaluate the efficacy of mycophenolate mofetil in the induction therapy of proliferative lupus nephritis.
                Forty-four patients from eight centres with newly diagnosed lupus nephritis World Health Organization class III or IV were randomly assigned to either mycophenolate mofetil (MMF) 2 g/day for 6 months or intravenous cyclophosphamide (IVC) 0.75-1 g/m(2) monthly for 6 months in addition to corticosteroids.
                Remission occurred in 13 out of 25 patients (52%) in the IVC group and 11 out of 19 patients (58%) in the MMF group (P = 0.70). There were 12% in the IVC group and 26% in the MMF group that achieved complete remission (P = 0.22). Improvements in haemoglobin, the erythrocyte sedimentation rate, serum albumin, serum complement, proteinuria, urinary activity, renal function and the Systemic Lupus Erythematosus Disease Activity Index score were similar in both groups. Twenty-four follow-up renal biopsies at the end of therapy showed a significant reduction in the activity score in both groups. The chronicity index increased in both groups but was only significant in the IVC group. Adverse events were similar. Major infections occurred in three patients in each group. There was no difference in gastrointestinal side-effects.
                MMF in combination with corticosteroids is an effective induction therapy for moderately severe proliferative lupus nephritis. Daclizumab and mycophenolate mofetil (MMF) decrease the incidence of acute allograft rejection. This double-blind, randomized, placebo-controlled trial was performed primarily to assess the pharmacokinetics of MMF in an immunosuppressive regimen incorporating daclizumab. At five centers, 75 renal transplant recipients were randomized 2:1 to receive either daclizumab 1 mg/kg or placebo pre-transplantation and every other week, for a total of five doses. All patients received cyclosporine, steroids, and MMF. Levels of mycophenolic acid (MPA), its glucuronide metabolite, and daclizumab were measured after dosing on days 28 and 56. Safety parameters evaluated included: adverse events, laboratory abnormalities, infections, patient/graft survival, incidence of lymphoproliferative disorders, and incidence of acute rejection at 12 months. The concomitant administration of daclizumab and MMF had no effect on the pharmacokinetics of MPA: AUC(0-8) values (microg h/mL +/- SD) on day 28 were 30.1 +/- 13.3 for daclizumab-treat patients vs. 31.1 +/- 12.4 for placebo and on day 56, 37.7 +/- 18.2 for daclizumab-treated patients vs. 35.7 +/- 14.0 for placebo. Adverse events were similar between the two groups. Acute rejection at 12 months occurred in 14% of patients receiving daclizumab and 20% of patients receiving placebo. The coadministration of daclizumab did not result in a pharmacokinetic interaction with MPA, the active metabolite of MMF. The success of liver transplantation in this decade has become the stimulus to extend the donor and recipient pool. Reducing early posttransplant morbidity to maintain our success, as we expand our frontiers, has led us to focus on balanced testing of multidrug immunosuppression regimens.
                A prospective trial in orthotopic liver transplantation using Mycophenolate Mofetil and an identical steroid taper with randomization of patients to Neoral (N) or Tacrolimus (FK) is the basis of this report. This was an intent-to-treat study designed to compare the 6-month primary endpoints of rejection and infection and to compare the 6-month secondary endpoints of liver function, renal function, bone marrow function, hypertension, and serum cholesterol levels.
                Ninety-seven patients completed the 6-month follow-up period (N=49, FK=48). The actual 6-month patient and graft survival rates were 98% and 94%, respectively. There was no difference in the number of patients with rejection episodes (N=11, FK=8) (P=0.61). There were 24 infections (3 cytomegalovirus) in the FK group and 30 infections (9 cytomegalovirus) in the N group. The cholesterol levels at 6 months were not significantly different (P=0.07) between the groups. The other secondary 6-month endpoints were not significantly different, except total bilirubin, which was lower in the FK arm (P=0.02).
                The use of Mycophenolate Mofetil with N or FK and an identical steroid taper after orthotopic liver transplantation is associated with excellent graft and patient survival, and at 6 months, only 191% of the patients experienced rejection, with a 48% overall infection rate. Recent studies have suggested that mycophenolate mofetil (MMF) may offer advantages over intravenous cyclophosphamide (IVC) for the treatment of lupus nephritis. The aim of this study was to evaluate the efficacy of MMF compared with IVC in the induction therapy of proliferative lupus nephritis.
                We randomly assigned 47 patients with newly diagnosed active proliferative lupus nephritis class III or IV to open-label oral MMF 2 g/day for 6 months or intravenous cyclophosphamide 0.5-1 g/m(2) monthly for 6 months in addition to corticosteroids.
                In the intention-to-treat analysis, 14 of the 24 patients (58.33%) receiving MMF and 12 of the 23 patients receiving cyclophosphamide (52.17%) had remission (P = 0.48); complete remission occurred in 6 of the 24 patients (25%) and 5 of the 23 patients (21.74%), respectively (P = 0.53). Improvements in packed cell volume, the erythrocyte sedimentation rate, anti-double-stranded DNA antibodies titer (anti-dsDNA), serum complement, proteinuria, urinary activity, renal function, serum soluble interleukin-2 receptor alpha concentration and the systemic lupus activity measure score were similar in both groups. Two patients assigned to MMF and another patient assigned to IVC developed end-stage renal failure with commencement of dialysis. Adverse events were similar. Major infections occurred in two patients in each group. There was no difference in gastrointestinal side effects, but more diarrhea occurred in those receiving MMF.
                In this 24-week trial, MMF or IVC combined with corticosteroids demonstrated equal efficacy in inducing remission of proliferative lupus nephritis. Since anecdotal series and small, prospective, controlled trials suggest that mycophenolate mofetil may be effective for treating lupus nephritis, larger trials are desirable.
                We conducted a 24-week randomized, open-label, noninferiority trial comparing oral mycophenolate mofetil (initial dose, 1000 mg per day, increased to 3000 mg per day) with monthly intravenous cyclophosphamide (0.5 g per square meter of body-surface area, increased to 1.0 g per square meter) as induction therapy for active lupus nephritis. A change to the alternative regimen was allowed at 12 weeks in patients who did not have an early response. The study protocol specified adjunctive care and the use and tapering of corticosteroids. The primary end point was complete remission at 24 weeks (normalization of abnormal renal measurements and maintenance of baseline normal measurements). A secondary end point was partial remission at 24 weeks.
                Of 140 patients recruited, 71 were randomly assigned to receive mycophenolate mofetil and 69 were randomly assigned to receive cyclophosphamide. At 12 weeks, 56 patients receiving mycophenolate mofetil and 42 receiving cyclophosphamide had satisfactory early responses. In the intention-to-treat analysis, 16 of the 71 patients (22.5 percent) receiving mycophenolate mofetil and 4 of the 69 patients receiving cyclophosphamide (5.8 percent) had complete remission, for an absolute difference of 16.7 percentage points (95 percent confidence interval, 5.6 to 27.9 percentage points; P=0.005), meeting the prespecified criteria for noninferiority and demonstrating the superiority of mycophenolate mofetil to cyclophosphamide. Partial remission occurred in 21 of the 71 patients (29.6 percent) and 17 of the 69 patients (24.6 percent), respectively (P=0.51). Three patients assigned to cyclophosphamide died, two during protocol therapy. Fewer severe infections and hospitalizations but more diarrhea occurred among those receiving mycophenolate.
                In this 24-week trial, mycophenolate mofetil was more effective than intravenous cyclophosphamide in inducing remission of lupus nephritis and had a more favorable safety profile.
                Copyright 2005 Massachusetts Medical Society. Long-term immunosuppressive treatment does not efficiently prevent relapses of lupus nephritis (LN). This investigator-initiated randomised trial tested whether mycophenolate mofetil (MMF) was superior to azathioprine (AZA) as maintenance treatment.
                A total of 105 patients with lupus with proliferative LN were included. All received three daily intravenous pulses of 750 mg methylprednisolone, followed by oral glucocorticoids and six fortnightly cyclophosphamide intravenous pulses of 500 mg. Based on randomisation performed at baseline, AZA (target dose: 2 mg/kg/day) or MMF (target dose: 2 g/day) was given at week 12. Analyses were by intent to treat. Time to renal flare was the primary end point. Mean (SD) follow-up of the intent-to-treat population was 48 (14) months.
                The baseline clinical, biological and pathological characteristics of patients allocated to AZA or MMF did not differ. Renal flares were observed in 13 (25%) AZA-treated and 10 (19%) MMF-treated patients. Time to renal flare, to severe systemic flare, to benign flare and to renal remission did not statistically differ. Over a 3-year period, 24 h proteinuria, serum creatinine, serum albumin, serum C3, haemoglobin and global disease activity scores improved similarly in both groups. Doubling of serum creatinine occurred in four AZA-treated and three MMF-treated patients. Adverse events did not differ between the groups except for haematological cytopenias, which were statistically more frequent in the AZA group (p=0.03) but led only one patient to drop out.
                Fewer renal flares were observed in patients receiving MMF but the difference did not reach statistical significance.
According to moderate quality evidence, mycophenolate mofetil did not produce significant benefit in terms of reducing need for intravenous immunoglobulin or improving muscle strength. Trials of other immunosuppressants should be undertaken.
