In France, chronic end-stage renal disease affects more than 11,000 new patients each year who will require dialysis or renal transplantation, of whom approximately 22.6% of new cases are related to diabetes. Among them, about 94% are managed by hemodialysis (HD), the others by peritoneal dialysis (PD). In addition, nearly 42% of dialysis patients have diabetes. There are issues related to glycemic control during dialysis and specific to each dialysis technique. Thus, hypoglycemic risk is the main risk observed during hemodialysis sessions, linked in particular to the use of a 1g/L glucose free dialysate, a decrease in renal neoglucogenesis and alterations in metabolic pathways. In addition, long-term glycemic control is difficult to assess in dialysis patients, because of the limitations of HbA1c witch is frequently underestimated.

This can be explained by 2 mechanisms:

• EPO treatment is associated with an increase in the proportion of young érythrocytes
• reduction in the lifetime of red blood cells reducing the duration of interaction between glucose and hemoglobin.

The results of studies conducted using continuous glucose measurements over a short period of time (48 hours to 5 days) suggest a benefit in using continuous glucose measurement to detect glycemic fluctuations during dialysis. To our knowledge, no studies have been conducted to evaluate longer-term glycemic control with this technology. In addition, the investigators now have the Freestyle, which allows us to record the continuous measurement of interstitial glucose over a longer period of time and is reimbursed for people on insulin basal-bolus protocol.

Thus, the investigators propose an observational study to evaluate glycemic control during dialysis sessions, but also to analyze the correlation between parameters measured with Freestyle and HbA1c measured routinely, according to the follow-up recommendations in diabetics.
