Preoperative Glycated Haemoglobin Level and Postoperative Morbidity and Mortality in Patients Scheduled for Liver Transplant.

Abstract

Background:There is high prevalence of diabetes mellitus in patients of end stage liver disease and it has been implicated for complications in post-transplant patients. Glycated hemoglobin is now targeted as a modifiable preoperative risk factors for postoperative complications. Data describing the course and severity of postoperative liver transplant complication and their relation with pre-operative glycated hemoglobin level is sparse. In this study, we looked for co-relation between the preoperative HbA1c level and post-operative mortality and morbidity in patients scheduled for liver transplant.Materials and Methods:Retrospective data in 400 adult patients operated for liver transplant were retrieved. After exclusion, data were analyzed for 224 patients. Patients were divided into two groups on the basis of glycated hemoglobin levels (Group 1 (HbA1C ≥6.5) and Group 2 (HbA1C <6.5)).Results:Glycated hemoglobin levels were not associated with postoperative death during stay in intensive care unit, incidence of postoperative cardiovascular, renal, and central nervous complications. No difference was seen between 2 groups for need for renal replacement therapy, incidence of infections, rejection, need for re-exploration surgery and duration of intensive care unit and hospital stay. Glycated hemoglobin cannot predict 30 day survival (Area under curve {AUC} = 0.629, P value 0.05).Conclusion:Preoperative glycated hemoglobin level is not associated with postoperative morbidity and mortality in patients scheduled for liver transplant.Trial Registration Number:CTRI/2018/04/012966.
