Cutaneous complications of chronic continuous subcutaneous insulin infusion therapy

The cutaneous complications that can develop with continuous subcutaneous insulin infusion constitutes a significant concern when using this innovative and highly effective form of treatment for type I diabetes. These complications are twofold, the first being infection with abscess formation at the infusion needle site. Proper hygiene and frequent changing of the infusion site are helpful and effective measures. The second complication is the development of local allergic skin reactions, again at the infusion needle site, even with highly purified pork insulin. These may subside after several weeks on their own but switching insulin preparations also may be helpful.
