MTOR and diabetes mellitus: The combined assessment of proteinuria predisposing factors (>0.3 g/24 h) such as DM before KT and NODAT in KT recipients and the use of immunosuppressants (prednisone and inhibitors of mammalian target of rapamycin (mTOR)) demonstrated that only a history of DM before KT was the risk factor for proteinuria (OR: 20.7; IC95%: 3.6–119.6).
