The Degree of Hyperglycemia Excursion in Patients of Kidney Transplantation (KT)‎ or Liver Transplantation (LT)‎ Assessed by Continuous Glucose Monitoring (CGM)‎: Pilot Study

الملخص EN

Objective.

This study used a continuous glucose monitoring system (CGMS) to investigate the glucose profiles and assess the degree of hyperglycemic excursion after kidney or liver transplantation during the early period after operation.

Methods.

Patients to whom a CGMS was attached during a postoperative period of approximately one month after transplantation were included.

The CGM data of 31 patients including 24 with kidney transplantation (KT) and seven with liver transplantation (LT) were analyzed.

Results.

Hyperglycemia over 126 mg/dL (fasting) or 200 g/dL (postprandial) occurred in 42.1% (8/19) and 16.7% (1/6) of KT and LT patients, respectively, during this early period after transplantation, except for patients with preexisting diabetes (5 KT, 1 LT).

The average mean amplitude of glycemic excursion (MAGE) and mean absolute glucose (MAG) levels were 91.18±26.51 vs.

65.66±22.55 (P<0.05) and 24.62±7.78 vs.

18.18±7.07 (P<0.05) in KT vs.

LT patients, respectively, in patients without preexisting DM or PTDM patients who showed normal glucose levels.

Average increase from the lowest level to the peak glucose value was higher in KT patients than LT patients (P<0.05).

Conclusions.

The transplanted organ also needs to be considered as an important factor affecting glucose control and the occurrence of more severe glucose excursions in patients who receive transplantation although immunosuppression agents are well-known important factors; however, our study was limited to the early posttransplantation period.

Further studies involving CGM follow-up at regular intervals based on the time since transplantation are needed.
