CSII is related to more stable glycemia in adults with type 1 diabetes.

PURPOSE

The purpose of the present study was to compare the basic glycemic control parameters-HbA1c, CV%, and hypoglycemia, as well as quality of life and depression score in patients with type 1 diabetes using continuous subcutaneous insulin infusion (CSII) versus multiple daily injections (MDI).

METHODS

324 adult patients with type 1 diabetes-146 using CSII and 178 on MDI, were enrolled in this cross-sectional study. HbA1c was assessed in whole blood by immuno-turbidimetric NGSP certified method. CV% was derived from CGM or was calculated from a 9-point capillary blood glucose profile. Hypoglycemia frequency, severity, and awareness were assessed using Clarke's hypoglycemia questionnaire. Quality of life (QOL) was assessed using a questionnaire by the Psychiatric Research Unit and the CES-D scale.

RESULTS

CSII group compared to MDI group showed significantly lower HbA1c-7.3% (6.6-8.0%) vs 8.2% (7.2-9.6%) (p < 0.0001), lower CV 27.2% (±9.8) vs 34.7% (±11.3) (p < 0.0001), fewer hypoglycemia episodes (p < 0.0001). There was no significant difference in the frequency of severe hypoglycemia, hypoglycemia awareness, QOL, and depression scores between the two groups.

CONCLUSIONS

CSII in type 1 diabetes is related to better and more stable glycemic control compared to MDI.
