INTRODUCTION: mTOR inhibitors alter lipids and carbohydrate metabolism in kidney transplant recipients. Little is known if there is any difference between patients who were already diabetics or not before transplantation.
METHODS: longitudinal 1-year long study in which we compared two different regimens based on tacrolimus and prednisone, one with mycophenolate (MP group) and one with a mTOR inhibitor (sirolimus/everolimus, mTORi group). The studied population included kidney transplant patients from June 2013 to May 2016 (n=272).
RESULTS: considering the whole population, the mTORi group had significant higher increase in HbA1c and triglycerides compared to MP group 1 year after transplant (MP +0.66 ± 1.38% vs mTORi +0.98 ± 1.13%, p=0.017 for HbA1c and MP +1.42 ± 85.83mg/dl vs mTORi +23.21 ± 95.87mg/dl, p= 0.003 for triglycerides).
When considering only diabetic patients at baseline (n=73), the increase in HbA1c was much more pronounced in mTORi group (MP group +0.7 ± 1.97% vs mTORi group +1.6 ± 1.31, p=0.020), while there was not any change in triglycerides between groups (p=0.879).
On the contrary, patients without diabetes at baseline (n=199) had a significant increase in triglycerides (MP +1.42 ± 85.83 mg/dl vs mTORi +23.21 ± 95.87 mg/dl, p=0.003), while no difference was observed in HbA1c (p=0.298). There was no difference in the incidence of de-novo diabetes after transplant between groups (p=0.272).
CONCLUSIONS: the change in HbA1c was mainly observed only in mTORi patients who were already diabetics before transplantation and there is not an increase in the incidence of de-novo diabetes in this group. Curiously, the increase in triglycerides was observed only in patients who were not diabetics before transplantation.
