Subcutaneous peritoneal access device for type I diabetic patients nonresponsive to subcutaneous insulin.

چکیده
Three type I diabetic patients nonresponsive to subcutaneous insulin were implanted with a subcutaneous peritoneal access device. In these patients, multiple subcutaneous injections had been unable to prevent recurrent hospital admissions for diabetic ketoacidosis. The patients were responsive to intravenous insulin but had limited accessible peripheral veins. Complications of thrombosis and/or septicemia from permanent central venous catheters prevented the long-term use of this route. The peritoneal access device was implanted subcutaneously adjacent to the umbilicus with its insulin delivery catheter terminating in the peritoneal space. Transcutaneous injection of insulin into the subcutaneous access port resulted in the same quantity of insulin entering the peritoneal space. Using a mixture of regular and protamine zinc insulin in a ration of 1:1 resulted in acute increases in plasma free insulin concentration with meals and a declining background level postprandially. All peritoneal access devices have been functioning well for at least 2 mo and in one of the implanted diabetic subjects, it has been in continuous use for 5 mo with no evidence of peritonitis or resistance to peritoneal insulin. These results suggest that a subcutaneous peritoneal access device may provide an alterative insulin delivery route for patients who are nonresponsive to subcutaneous insulin injections.

Administration of insulin by continuous ambulatory peritoneal dialysis.
Many patients with diabetic nephropathy undergoing continuous ambulatory peritoneal dialysis (CAPD) use their peritoneal access to administer insulin. Compared with the subcutaneous route, intraperitoneal (IP) insulin may display more consistent absorption, produce more physiologic insulin concentrations, and be more convenient to administer. However, there are no well-controlled trials that ha...
متن کاملComparing Effects of Continuous Insulin Infusion with or without Subcutaneous Glargine Insulin on Glycemic Control in Diabetic Patients Undergoing Coronary Artery Bypass Graft (CABG)
OBJECTIVE: Hyperglycemia is associated with increased morbidity and mortality in diabetic patients following coronary artery bypass grafting. Tight glycemic control in perioperative period can reduce these events. The goal of this study was to determine whether combination of continuous infusion and subcutaneous glargine as a basal insulin could improve glycemic control. MATERIAL AND METHODS:...

Over Expression of FOXO1 in Subcutaneous Fatty Tissue and its Response to Resistance Training in High Fat Diet and Type 2 Diabetic Rat
Objective: Forkhead box proteins and Forkhead box transcription factor O1 (FOXO1) in particular, mediate insulin signaling pathways and glucose homeostasis. This study aimed to compare FOXO1 expression in subcutaneous adipose (SA) tissue between obese rats with and without type 2 diabetes (T2D) and its response to resistance training in T2D. Materials and Methods: 21 male wistar rats (220±20 g...
متن کاملThe influence of peritoneal dialysis and the use of subcutaneous and intraperitoneal insulin on glucose metabolism and serum lipids in type 1 diabetic patients.
BACKGROUND Intraperitoneally administered insulin is regarded as the most physiological replacement therapy, leading to lower peripheral insulin concentrations and equal or better glycaemic control than subcutaneous insulin. This two-part study was undertaken to evaluate the effect of CAPD, as well as the use of subcutaneous vs. intraperitoneal insulin on insulin sensitivity, glycaemic control ...
