Laser treatment for lipoatrophy in children with diabetes type 1.

Introduction: Lipoatrophy (LA) is one of the complications of insulin treatment. It has become rare thanks to insulin analogues but it can still be observed in patients with diabetes type 1(T1DM). No effective treatment exists. Herein, we report for the first time two children with T1DM and LA successfully treated with laser treatment. Clinical cases: A 6-year-old child with T1DM presented with LA 4 months post-diagnosis. He was on continuous subcutaneous insulin infusion (CSII). LA presented on body sites where insulin catheter was never inserted. He underwent different treatment options with no positive effect. Laser treatment was tried with impressive improvement. The second 9-year-old child presented with LA 5 years postdiagnosis. He changed the insulin type, the site of insulin injection, and tried topical use of sodium chromoglycate cream with partial improvement. Laser treatment was finally used with remarkable outcome.
Conclusion: Insulin-induced LA is now a rare skin complication with no effective treatment up to now. Laser treatment seems to be an effective treatment option. © The Japan Diabetes Society 2021.
