Study of Renal Blood Flow During Human Endotoxemia
Summary
The purpose of the present protocol is to study whether endotoxemia will affect the renal blood flow in type 2 diabetics and healthy volunteers.
Description
Many septic patients develop acute renal failure and the risk is higher in patients with diabetes. The pathogenetic mechanisms behind the development of acute renal failure in connection with sepsis is not completely understood. One among many possible explanations is a change in renal hemodynamics. However, it is still largely unknown what happens to the renal plasma flow during human sepsis. In this study we give endotoxin injection (0,3 ng/kg) to type 2 diabetics and healthy controls as an experimental model of sepsis. Renal plasma flow and glomerular filtration rate are measured by DTPA-renography 1 day before before and 1,25 and 6,5 hours after injection of endotoxin. Furthermore WBC, plasma-cytokines,VCAM-1/ICAM-1, endothelin-1, Thromboxane B2, angiotensin 2, renin and PAI-1 are measured on an hourly basis up to 8 hours after endotoxin injection.

Medical and Biotech [MESH] Definitions
Enterohemorrhagic Escherichia Coli
Strains of ESCHERICHIA COLI that are a subgroup of SHIGA-TOXIGENIC ESCHERICHIA COLI. They cause non-bloody and bloody DIARRHEA; HEMOLYTIC UREMIC SYNDROME; and hemorrhagic COLITIS. An important member of this subgroup is ESCHERICHIA COLI O157-H7.
Escherichia Coli K12
A species of gram-negative, rod-shaped bacteria belonging to the K serogroup of ESCHERICHIA COLI. It lives as a harmless inhabitant of the human LARGE INTESTINE and is widely used in medical and GENETIC RESEARCH.
Escherichia Coli O157
A verocytotoxin-producing serogroup belonging to the O subfamily of Escherichia coli which has been shown to cause severe food-borne disease. A strain from this serogroup, serotype H7, which produces SHIGA TOXINS, has been linked to human disease outbreaks resulting from contamination of foods by E. coli O157 from bovine origin.
Escherichia Coli Vaccines
Vaccines or candidate vaccines used to prevent or treat both enterotoxigenic and enteropathogenic Escherichia coli infections.
Uropathogenic Escherichia Coli
Strains of Escherichia coli that preferentially grow and persist within the urinary tract. They exhibit certain virulence factors and strategies that cause urinary tract infections.
