Intraperitoneal insulin absorption after long-term intraperitoneal insulin therapy.
OBJECTIVE
To evaluate insulin absorption through the peritoneal membrane after long-term intraperitoneal insulin therapy using an implanted programmable device.


METHODS
Seven insulin-dependent diabetes mellitus (IDDM) patients implanted with a programmable pump were studied after 3 and 30 months of intraperitoneal insulin therapy. A 20-min square wave infusion of 15 IU of insulin was administered in the peritoneal space, and plasma glucose and plasma free insulin levels were monitored for 180 min. Hypoglycemia was prevented by intravenous glucose infusion.


RESULTS
After 30 months of intraperitoneal insulin therapy, plasma free insulin profiles following the administration of insulin in the peritoneal space were similar to those observed at the beginning of this mode of therapy.


CONCLUSIONS
In IDDM patients, intraperitoneal insulin absorption does not change after long-term intraperitoneal insulin therapy using an implanted device.
