Title: Use of a Real Time Continuous Glucose Monitoring System (RT-CGMS) in Type 1 Diabetes Patients on Continuous Intraperitoneal Insulin Infusion (CIPII. A Feasibility Study
Brief Summary: To investigate the effectiveness and safety of a Real Time Continuous Glucose Monitoring System (RT-CGMS in a population of patients with type 1 diabetes mellitus treated with insulin through an implanted pump.


Options:
A: Inclusion Criteria:

* Patient has signed informed consent form prior to study entry.
* Patients have been diagnosed with Type 1 DM at least 12 months prior to inclusion.
* Patients should have been received diabetes care from the investigator of each center at least 3 months prior to inclusion.
* Patients have been treated with multiple daily injections and use rapid Insulin Analog for their meal prior to study entry.

* Pediatric patients must be aged between 2 and 18 years old and adult patients be aged between 19 and 65 years old.
* Patients must perform at least 3 self-monitoring blood glucose finger-sticks daily.
* Patients from PRT group must be willing to wear sensors and transmitter connected to the pump Paradigm® Real-Time for up to 24 weeks and to change sensors, insulin infusion sets and reservoirs every 3 days (\~60 times during the study period ).
* Patients from CSII group must be willing to wear an insulin pump, change insulin infusion sets, and reservoirs every 3 days (\~60 times during the study period ).
* Patient is required to use the Paradigm® Real-Time system at least 70% of the time during the study period.
* Patients in both groups are required to wear at the beginning and the end of the study a CGMS for 3 days. and to perform 6 self-monitoring blood glucose finger-sticks daily during the 3 days.
* Patients must be willing to undergo all study procedures, to receive a technical training to understand how to use the Paradigm® Real-Time System or the Insulin Pump depending of the randomization.
* Patients must agree to receive a training on how to adapt their insulin doses to their meals, how to calculate and apply corrective treatment.
