Renal glucose transport after kidney transplantation

Tubular maximal transport of glucose (TmG), plasma glucose threshold ( PGT ) and fractional maximal tubular reabsorption (TmG/GFR) were measured in fourteen kidney-grafted patients. Seven patients showed decreased PGT and normal or decreased TmG/GFR (type A or B renal glycosuria (RG) ), whereas seven other patients showed normal values. No difference was found between the two groups with respect to parameters of renal function and to clinical parameters characterizing kidney transplantation. The only difference observed between the two groups was the rate of decrease of plasma creatinine levels during the 1st week after transplantation: it was faster in the group without renal glycosuria. No difference was seen between the two groups of patients with respect to the number of rejection episodes occurred over the first 12 months.
