Proteomic Analysis Reveals Innate Immune Activity In Intestinal Transplant Dysfunction
Many patients with intestinal failure require intestinal transplantation for survival. Currently, the gold standard for diagnosing acute cellular rejection (ACR) is histological examination of endoscopic biopsies, which are taken invasively and lack sensitivity. A non-invasive method of monitoring for ACR is needed.

- Evaluate levels of proteins and cytokines in ostomy effluent during episodes of rejection [ Time Frame: first 8 weeks post transplant ] [ Designated as safety issue: No ]
Protocol biopsies of the transplanted intestine are obtained during endoscopy and when clinical symptoms indicating abnormal allograft function are present. Biopsies were sent to pathology, where the pathologist determined if there was acute rejection.
Ostomy effluent taken during times of endoscopy were subjected to MALDI and Luminex technology to look for any proteins or cytokines differentially expressed during rejection.
