Clinical TrialMycophenolate mofetil versus azathioprine immunosuppressive regimens after lung transplantation: preliminary experience.
Mycophenolate mofetil reduces episodes of biopsy-proven acute cellular rejection or treatment failure in the first year after kidney transplantation; however, limited data exist regarding the efficacy after lung transplantation. ⋯ Our preliminary experience with mycophenolate mofetil after lung transplantation suggests a decreased incidence of biopsy-proven acute cellular rejection. Furthermore, less decline in FEV1 after 12 months may suggest a reduced incidence or delayed onset for development of bronchiolitis obliterans syndrome. Prospective randomized trials with low beta error (level I evidence) should be performed to assess the efficacy of mycophenolate mofetil vis-à-vis acute allograft rejection and bronchiolitis obliterans syndrome.

Outpatient inotropic therapy in heart transplant candidates: should its use influence waiting list priority status?
The use of outpatient intravenous inotropic therapy in heart transplant candidates is contentious. In addition to concerns about morbidity and mortality rates, the current United Network for Organ Sharing (UNOS) heart allocation system presently grants no waiting list priority status benefit to candidates who receive intravenous inotropic therapy in the outpatient setting (UNOS status 2), whereas identical therapy given in an intensive care unit setting does increase priority status (UNOS status 1). The goal of this study was to determine whether an increase in UNOS waiting list priority status is justified in heart transplant candidates receiving outpatient intravenous inotropic therapy by comparing the waiting list mortality of UNOS status 2 candidates on such therapy with that of UNOS status 2 candidates maintained on oral heart failure agents alone. ⋯ This study suggests that heart transplant candidates who require maintenance outpatient intravenous inotropic therapy represent a subgroup of UNOS status 2 candidates with greater waiting list morbidity, but no greater waiting list mortality than candidates who can be maintained on oral heart failure agents alone. However, the current UNOS heart allocation system provides for this increased illness acuity by assigning a higher priority status when necessary. A larger, prospective study is necessary to determine whether a true difference in waiting list mortality rates exists and if an increase in priority status is justified for UNOS status 2 candidates requiring maintenance inotropic therapy.
