Organized Management of Diabetes Mellitus in Lung Transplantation: Study of Glycemic Control and Patient Survival in a Single Center

Abstract

ObjectiveTo study patient survival and glycemic control before and after lung transplantation (LTx) according to the diabetes status in patients submitted to an organized management of diabetes mellitus (DM) at the Strasbourg University Hospital, France. Material and MethodsTwo hundred and sixty-seven LTx recipients were included retrospectively and analyzed according to diabetes status: pretransplant diabetes, new-onset diabetes mellitus after transplant (NODAT) or no diabetes. Organized DM management was coordinated by a diabetologist trained in DM management before and after transplantation and included pretransplant screening, a close monitoring of glycemia after transplant and optimized treatment before and after LTx. ResultsDM was well-controlled after transplantation: mean glycosylated hemoglobin and fasting blood glucose levels after LTx were 5.8 ± 0.2% and 5.4 ± 0.1 mmol/L respectively, in pretransplant DM patients and 5.7 ± 0.1% and 5.6 ± 0.2 mmol/L respectively, in NODAT patients. The overall median survival time was 8.3 ± 1.9 years. Pretransplant DM increased the risk of mortality (1.82-fold increase; 95% confidence interval, 1.08-3.06; P = .02) in LTx recipients. ConclusionsOrganized management of diabetes achieved very satisfactory glycemic control in both pretransplant DM and NODAT patients. However, no specific protocols have been created for managing DM following LTx. As DM continues to become an increasing comorbidity in LTx, there exist a significant need of studies in this area.
