Comparison of New Onset Diabetes according to the Time of Onset in Kidney Transplant Recipients / 대한이식학회지

ABSTRACT

BACKGROUND: New onset diabetes is a common complication after kidney transplantation. However, the clinical course of post-transplant diabetes mellitus (PTDM) remains unclear. The aim of the present study is to analyze the natural courses and risk factors of PTDM according to the time of onset. METHODS: A total of 216 consecutive kidney transplant recipients were enrolled and patient medical records were investigated retrospectively. PTDM was defined as glucose > or =126mg without previous diabetic history. Patients were classified according to the onset (12 months) early PTDM (E-PTDM) and late PTDM (L-PTDM). RESULTS: PTDM was observed in 34 (17.4%) patients. The number of E-PTDM and L-PTDM patients was 17 and 17. Compared with normoglycemic patients, the PTDM group was older and showed higher pre-transplant HbA1c level. The use of tacrolimus was associated with the development of E-PTDM (OR=4.87, 1.71~13.8 in 95% CI) but not L-PTDM (OR=0.34, 0.04~2.70 in 95% CI) CONCLUSIONS: The development of E-PTDM and L-PTDM may have different risk factors. It will be important to choose different therapeutic strategy according to the onset of PTDM.
