Introduction New-onset diabetes after transplantation (NODAT) is a serious and common complication after kidney transplantation. Insulin resistance, together with β-cell dysfunction, plays an essential role in the development of diabetes. Homeostasis model assessment of insulin resistance (HOMA-IR), which is calculated as [fasting plasma glucose (mmol/L) × fasting insulin (mU/L)]/22.5, is widely used as an index of insulin resistance. However, the correlation between pretransplant HOMA-IR and the development of NODAT has not been fully established. Methods We performed a retrospective study of 44 nondiabetic patients who underwent living donor kidney transplantation in our hospital from July 2006 to October 2009. We compared the HOMA-IR and demographic variables of patients who developed NODAT with those who did not. Results Five patients (11.4%) developed NODAT within 3 years after transplantation. There were no differences in demographic variables between patients who developed NODAT and those who did not. Logistic regression analysis revealed that HOMA-IR was a predictive factor of NODAT (odds ratio, 2.88; 95% CI, 1.11-9.59; P <.05). Conclusions Our results indicate that high HOMA-IR might be an important predictive factor for NODAT. These findings underline the importance of routine pretransplant measurements of fasting plasma glucose and serum insulin for evaluating HOMA-IR.
