Fecal Transplantation Using a Diet for Donor and Recipient in Refractory Colitis

The investigators propose to modify FT using a novel protocol and approach that we have developed. We have developed a unique diet that is geared to rectify dysbiosis in UC and damage to the mucous layer in active UC. The investigators intend to condition both donor and recipient with the diet to achieve optimal conditions for transplant to succeed for both donor and recipient .The investigators intend to evaluate this protocol in adults with active UC that are refractory to medications. The investigators will start with a randomized controlled trial involving 76 transplanted patients, however in the first pilot stage The investigators will enroll 34 patients, and extend the study if there is a trend for better outcomes with the dietary conditioning protocol. Furthermore, The investigators hope to identify successful donors during this period to use during the study extension.
