Outcomes of patients with cystic fibrosis undergoing lung transplantation with and without cystic fibrosis-associated liver cirrhosis

Abstract

People with severe cystic fibrosis (CF) lung disease with co-existent CF-associated liver disease (CFLD) are often excluded from consideration of sole lung transplantation, largely because of the concerns that they will subsequently develop hepatic decompensation. This retrospective cohort study aimed at determining whether patients with severe cirrhosis caused by CFLD have any differences in perioperative and relevant post-transplant outcomes compared to CF patients without CFLD when undergoing sole lung transplantation. Six patients with CFLD were matched with 18 CF patients without CFLD undergoing sole lung transplant at the same institution. There were no differences in total operative time or intra-operative requirements for cardiopulmonary bypass or blood products. Over a period of five yr post-transplant, no differences were observed between the two groups in body mass index, six-min walk, lung function, and survival. None of the CFLD subjects developed variceal bleeding; however, one developed hepatocellular and renal failure at four yr post-transplant and is being assessed for liver-kidney transplant. One additional patient with CFLD required repeat lung transplantation for bronchiolitis obliterans syndrome. This study provides evidence that CF patients with liver cirrhosis caused by CFLD can safely be considered for sole lung transplantation provided there is no evidence of significant hepatocellular dysfunction with decompensated cirrhosis or hepatic synthetic failure.
