Beneficial Effect of Insulin Glulisine by Lipoatrophy and Type 1 Diabetes (LAS)

The purpose of this study is to investigate whether a zinc-free insulin is an effective treatment option for lipoatrophy in patients with type 1 Diabetes (T1D) and insulin pump (CSII, continuous subcutaneous insulin infusion) therapy.

Randomized, controlled, open-label parallel study. Clinical Study Phase IV After being included in the study, subjects are getting an extensive dermatological examination by a pediatric dermatologist familiar with cutaneous complications of T1D, additionally pathological results will be documented by photography and, if necessary, videodermoscopy. Additionally, an evaluation of their lipoatrophic areas using imaging methods like ultrasound (USG) and MRI will be performed. After randomization, half of the included children switch their pump insulin into insulin glulisine (intervention group) for 6 months. The others continue their current treatment (control group) and switch to insulin glulisine 6 months later. Both groups are followed-up until month 12. Hence, after the 4th visit at 6 months, all enrolled patients are on insulin glulisine pumps for a further period of 6 months.
