Successful treatment with insulin analog lispro in IDDM with delayed absorption of subcutaneously applied human regular insulin and complicated intraperitoneal insulin infusion. A case report.

OBJECTIVE: To subcutaneously administer the insulin analog lispro in a patient with delayed absorption of subcutaneously applied human regular insulin whose continuous intraperitoneal insulin infusion (CIPII) with a percutaneous access device had required multiple surgical interventions because of complications.

RESEARCH DESIGN AND METHODS: In a 35-year-old woman with long-term IDDM and delayed absorption of subcutaneously applied human regular insulin, a 3-year CIPII with human regular insulin via a percutaneous access device was complicated by three catheter obstructions and one subcutaneous abscess. Each complication required the implantation of a new percutaneous access device. During a 2-day trial with continuous subcutaneous insulin infusion (CSII) of the insulin analog lispro at basal infusion rates of 0.5-1.1 U/h, stable metabolic control was achieved. A 5-h intermediate attempt with human regular insulin in CSII, however, increased blood glucose concentrations from 6.0 to 28.8 mmol/l, despite identical basal rates and additional injection of 16 U of human regular insulin. Restarting with CSII of the insulin analog lispro reinforced stable metabolic control.

CONCLUSIONS: It is suggested that the insulin analog lispro is a promising approach in the treatment of IDDM with delayed absorption of subcutaneously applied human regular insulin and a suitable alternative therapy for patients with complications attributed to percutaneous access devices for CIPII.
