RESUMO
Obesity at the time of lung transplant is associated with decreased survival. How providers manage obesity after lung transplantation is unknown. We performed an international survey of lung transplant providers to assess beliefs and practices regarding post-transplant obesity management. Eighty-one providers initiated the survey and 73 (90%) completed the full survey. Respondents were primarily North American-based pulmonary physicians. Nearly all providers believe treating obesity improves quality of life (99%) and survival (95%) after lung transplantation, but that only 41% of patients attempting weight loss are successful. While respondents nearly always recommend diet (96%), exercise (92%), and dietician consultation (89%), they less frequently recommend prescription weight loss medications (29%) or bariatric surgery (11%). Lung transplant providers are motivated to treat obesity in transplant recipients. However, there is a gap between general obesity treatment guidelines and lung transplant practice. Additional training, education, and trials in this population could address this gap.
RESUMO
BACKGROUND: Optimal immunosuppression in elderly kidney transplant recipients (KTRs) is not well defined, with mycophenolate mofetil (MMF) being poorly tolerated. Study aim was to compare MMF dose reduction incidence and reason(s) in elderly vs. nonelderly KTRs in the 1st year after transplant with a protocol dose of 1 g/day. METHODS: In this single-center retrospective study, first or repeat KTRs receiving rabbit antithymocyte globulin (rATG), MMF 1 g/day, tacrolimus, and prednisone, were stratified by age [≥60 (elderly) or <60 years (nonelderly)]. Primary outcome was MMF dose reduction incidence in the first year. Secondary outcomes included dose reduction rationale, 1-year patient and graft survival, graft function, rejection, infection, hospital presentation, and time to dose reduction. Of 335 KTRs, dose reduction incidence was significantly greater in the elderly group (66% and 54%, p = 0.04), though this did not remain significant when adjusted for sex, race, and valganciclovir use. Most common rationale was leukopenia in the elderly group and CMV in the nonelderly group. There were no significant differences in secondary outcomes. CONCLUSIONS: Mycophenolate mofetil 1 g/day was poorly tolerated in both elderly and nonelderly KTRs receiving lymphocyte-depleting induction with a high incidence of dose reductions; however, no short-term adverse graft outcomes were identified.
