Understand the Association Between Peritoneal Dialysis Status and Gene Polymorphisms of VEGF and KDR

Gene Polymorphisms of VEGF and KDR Are Associated With Initial High Transport Status in Peritoneal Dialysis

Peritoneal dialysis (PD) is an effective and successful way of renal replacement therapy. The initial transport status is related to distribution of blood vessels and micro inflammation state in peritoneum before PD. Vascular endothelial growth factor(VEGF) and its receptor, kinase insert domain containing receptor(KDR) may play important roles on initial transport status.

This study include 200 PD patients from Renji Hospital in Shanghai, China. According to the 4h D/P Cr within three months of starting PD therapy, we analyzed the association between the polymorphisms of VEGF and KDR and initial peritoneal transport property.

Inclusion Criteria:

1. Patients are Han Chinese;
2. Patients prepare for dialysis in our center, and start PD within 3 months after abdominal catheterization;
3. Patients successfully complete the first peritoneal equilibration test(PET);
4. Follow up regularly in our PD center.

Exclusion Criteria:

1. Patients from hemodialysis to peritoneal dialysis;
2. Patients who need peritoneal dialysis due to transplant-renal loss;
