ABSTRACT
Post-transplantation diabetes mellitus (PTDM) is an important complication related to kidney transplantation (KT), and its occurrence is associated with increased morbidity and mortality. Nevertheless, KT is considered to be the most effective treatment option that offers better quality of life for patients with end-stage kidney disease. This study aimed to describe the occurrence of PTDM and the risk factors associated with its development in kidney transplant patients of a transplantation reference center in the State of Ceará (Brazil). This historical cohort study, based on medical records data, included adult patients undergoing KT from January 2006 to December 2010 in a public tertiary hospital. Multivariate analysis was performed with the use of a logistic regression model, with PTDM presence as dependent variable and the possible risk factors under study as independent variables. Throughout the evaluated period, 430 KTs were performed; 92 patients were excluded. Diabetes mellitus was already present in 9.2% of patients before KT. Hyperglycemia during the 1st month after transplantation occurred in 34.5% of recipients, and the occurrence of PTDM to the end of study was 19.9%. Factors associated with PTDM development were: fasting plasma glucose 1 month after KT (P < .001; odds ratio [OR] 1.05), deceased-donor KT (P = .015; OR 3.53), impaired fasting glucose before transplantation (P = .014; OR 4.10), and acute rejection occurrence (P = .003; OR 6.43). High PTDM occurrence was found, in accordance with the literature. Identification of factors associated with PTDM development, as well as its early diagnosis, could result in long-term improvement in patient and graft survivals.
