Body Mass Index Recovery after Lung Transplant for Cystic Fibrosis.

Many lung transplant recipients with cystic fibrosis (CF) have low preoperative body mass index (BMI); however, post-transplant BMI recovery is not well understood. To evaluate BMI recovery (⩾18.5 kg/m) among CF lung transplant recipients with low preoperative BMI and to investigate the association of survival with BMI recovery.

Low body mass index as a barrier to lung transplant in cystic fibrosis.

Rationale: Low body mass index (BMI) may influence lung transplant decisions for patients with advanced cystic fibrosis (CF) lung disease.

Objective: Determine whether patients with advanced CF lung disease and BMI ≤17 kg/m are less likely to be listed for lung transplant or have a higher risk of death without listing compared to those with higher BMI.

Methods: Using merged United Network for Organ Sharing and CF Foundation Patient Registries, we identified adults with onset of advanced lung disease (FEV ≤ 40% predicted) between May-2005 and December-2016.
