Insulin Pump vs Multiple Daily Injections of Insulin and Glyco-metabolic Control in Type 1 Diabetic Patients

Phase 4
Recruiting
Conditions
Type 1 Diabetes Mellitus
Interventions
Drug: Insulin injections
Device: Insulin pump
Registration Number
NCT03463564
Lead Sponsor
University of Campania "Luigi Vanvitelli"
Brief Summary

The transition from the Pediatric clinic to the adult care is a challenging period for young adults with type 1 diabetes, due to the high risk of poor glycemic control. Achieving the glycemic target without hypoglycemia and/or large glucose excursions is of paramount importance for type 1 diabetic patients, who have high variability of daily glucose levels . Both insulin pump therapy and multiple daily injections of insulin are recommended strategy to achieve glycemic control in type 1 diabetes; however, no studies investigated the effects of insulin pump vs insulin injections on glycol-metabolic outcomes in the transition phase. The aim of this study was to evaluate the effects of continuous subcutaneous insulin infusion (CSII) therapy, as compared with multiple daily injections of insulin (MDI), on glycemic and metabolic control, in young type 1 diabetic patients transitioned to the adult diabetes care.

Primary Outcome Measures
NameTimeMethod
Change in mean amplitude glucose excursions (MAGEBaseline, 6 months, 12 months, 24 months

Within and between groups difference in glucose variability measured as mean amplitude of glucose excursions (MAGE).

HbA1c changeBaseline, 6 months, 12 months, 24 months

Within and between groups difference in HbA1c levels

Change in glucose variabilityBaseline, 6 months, 12 months, 24 months

Within and between groups difference in time in the euglycemic range, defined as the minutes per day spent in glucose levels ranging between 70-180 mg/dL

Change in coefficient of variation (CV)Baseline, 6 months, 12 months, 24 months

Within and between groups difference in glucose variability measured as coefficient of variation (CV).

Change in standard deviation (SD) of mean glucose levelsBaseline, 6 months, 12 months, 24 months

Within and between groups difference in glucose variability measured as standard deviation (SD) of mean glucose levels

Secondary Outcome Measures
NameTimeMethod
Occurrence of hypoglycemic eventsThrough study completion, an average of 1 year

Number of events of mild hypoglycemia (glucose levels below 70 mg/dl), or severe hypoglycemia (below 54 mg/dl or each episode of low glucose levels requiring assistance)

Change in weightBaseline, 12 months, 24 months
Total daily insulin doses/KgBaseline, 12 months, 24 months
Change in lipid profileBaseline, 12 months, 24 months

Difference between groups in total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides

Diabetes treatment satisfactionBaseline, 12 months, 24 months

In order to measure satisfaction with diabetes treatment regimens, we used the self-reported Diabetes Treatment Satisfaction Questionnaire. This instrument aims to assess levels of satisfaction in subjects using different treatment strategies. The questionnaire consists of eight questions: six questions addresses general satisfaction with a score from 0 to 6 for each question (0 = worst), that has to be computed in a total score ranging from 0 (=worst) to 36 (=best); among the remaining two questions, which has to be computed separately as two subscales, one concerns the perception of hyperglycemic events and another the perception of hypoglycemic events, both with a score from 0 (none of the time) to 6 (most of the time).
