Diabetes mellitus and survival in cystic fibrosis patients after lung transplantation

BackgroundDiabetes mellitus (DM) is common in CF and associated with more severe disease. It is unclear whether DM influences outcome of lung transplantation (LTx).MethodsOne hundred twenty-three CF patients evaluated for LTx at our centre were included. Survival was calculated.ResultsPatients with and without DM did not differ with regard to gender, age, FEV1 and BMI prior to LTx. Eighty patients (65%) had a diagnosis of DM before and 13 (11%) only after LTx. Recipients with DM had a significantly higher 1- and 5-year survival (89% and 71%) than those without (71% and 51%). In the multivariate Cox-regression analysis, DM had no impact on LTx-survival.ConclusionsOne- and five-year survival rates after LTx tend to be better in CF recipients with DM compared to those without DM. No impact of DM on the development of BOS was found.
