Influence of the Intestinal Microbiota on the Clinical Course of Renal Transplantation

• Status: Unknown
• Phase: N/A
• Study type: Interventional
• Enrollment: 50 (estimated)
• Sponsor: Fundacion para la Investigacion Biomedica del Hospital Universitario Ramon y Cajal · Academic / Other
• Sex: All
• Age: 18 Years
• Healthy volunteers: Not accepted

Summary

ACKGROUND: The development of new molecular techniques, in recent years, has increasing the knowledge of the composition and functionality of the intestinal microbiota. In the area of kidney transplantation, observational studies have described a change in the intestinal microbiota during the immediate post-transplantation period that seems to be related to the appearance of clinical outcomes such as diarrhea, repeated urinary tract infections, the need for adjustment of immunosuppressive treatment or acute rejection. However, intervention studies on this subject are necessary to determine how far the microbiota can influence in the development of these events. OBJECTIVE: To clarify the influence of maintaining the composition and functionality of the intestinal microbiota on post-transplant clinical outcomes such as diarrhea, urinary tract infections, kidney graft rejection and the need for dose adjustment of immunosuppressive therapy. MATERIALS AND METHODS: single-center, randomized, interventional pilot study with 50 deceased kidney donor transplant patients at low immunological risk. Each patient will be randomized at the time of inclusion in the study to one of the 2 branches of the study: 1) Intervention group: 25 patients who will receive a autologous fecal matter transfer during the first 6 months post-transplantation, 2) Control group: 25 renal transplant patients with the same characteristics who will not receive any type of intervention in addition to the immunosuppressive treatment indicated according to hospital protocol.
