Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Aim/hypothesis: Subcutaneous insulin absorption is one of the factors which strongly influence blood sugar control in patients with diabetes mellitus on insulin therapy. In response, a regular absorption is influenced by lipo-hypertrophy in subcutaneous tissue on injection sites. So far lipo-hypertrophy diagnosis has only been clinical since there are no imaging studies that have characterized precisely morphometry of lipo-hypertrophic tissue. Methods: In two groups of 20 type 1 diabetes patients on insulin therapy, lipo-hypertrophy is characterized and defined by clinical tapping or by ultrasound with multi frequency linear probe (6-18 Mhz). Patients are therefore advised to avoid insulin injections on those areas so defined. Patients are reevaluated 3 and 12 months later

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

An observational study has been carried out, checked with parallel arms in which type 1 diabetes patients are recruited with clinical evidence of lypo-hypertrophy in insulin injected areas. Patients attend to the Diabetes Unit of Niguarda Ca' Granda Hospital. Obese patients with a thickening fat subcutaneous tissue that could have interfered with the interpreting and analyzing of the data are left out of this first study. In the control group the investigators manage to define the lypo-hypertrophic area by tapping and body inspection. In the study group the investigators can define and mark out the area/areas with lipo-hypertrophy by ultrasound scan test. All the tested patients both the control group and the study group, are discouraged from use insulin in areas where lypo-hypertrophy is present. Patients are reassessed after 3 months with a clinical assessment of glucose control by HbA1c. After 12 months subcutaneous tissue scan is repeated in 10 patients within the experimental group and a new assessment of HbA1c is performed. Ultrasound assessment. The scan used is Esaote My Lab70 linear probe multi-frequency \[6-18 Mhz)
