Brief Summary

Pancreas Kidney Transplantation (PKT) is the prominent treatment for type 1 diabetic patients with chronic kidney disease and improves patients' outcome. However, in spite of an optimized systemic insulin substitution, altered glucose metabolism and beta cell function are reported in these patients. The mechanisms behind these abnormalities are still unclear. Duodena-pancreatic anastomosis is performed in a heterotopic site (ileum) and thus could change physical and chemical properties of intestinal secretions, gut flora, as well as intestinal permeability. The effect of this procedure on gut derived metabolic factors, the enterohepatic cycle of bile acids, incretin secretion and intestinal flora have never been studied. This pilot prospective, study is aimed to evaluate the modification of bile acids concentrations and composition in PKT subjects, and the impact in glucose and incretin metabolism (measured by oral glucose tolerance test) one year after transplantation. The results will be compared to those of kidney transplant patients and control subjects.

Primary Outcome Measures
NameTimeMethod
Bile acids compositionOne year after transplantation

Plasmatic bile acids composition will be assessed in serum by gas chromatography

Bile acids concentrationsOne year after transplantation

Plasmatic bile acids concentration will be measured in serum by biochemical analysis

Secondary Outcome Measures
NameTimeMethod
Relationship between bile acid modifications and Oral Glucose Tolerance test (OGT) measuresOne year after transplantation

OGT will be performed in all subjects. Data on insulin sensitivity and secretion, Glucagon-Like Peptide 1 (GLP-1) and fibroblast growth factor-19 will be collected

Impact of Pancreas-Kidney Transplantation (PKT) on LipoPolySaccharides (LPS)One year after transplantation

LPS level will be measured before transplantation and one year after transplantation

Impact of PKT on intestinal floraOne year

Gut microbiota will be analysed before and after transplantation
