Bacteriotherapy for clostridium difficile colitis
This document discusses, among other things, receiving a plurality of donor fecal samples from a plurality of donors and storing and indexing each respective donor fecal samples using at least one characteristic of the respective donor fecal sample. In an example, the donor fecal sample can be screened and processed for subsequent use in fecal bacteriotherapy to displace pathogenic or undesired organisms in the digestive track of a patient with healthy or desirable gut micriobiota.
1. A method for treating a digestive disorder, the method comprising:
preparing a first bacteriotherapy composition by
obtaining a first donor fecal sample from a first donor, homogenizing the first donor fecal sample with at least one cryoprotectant, and then filtering, and
wherein the cryoprotectant includes a glycol;
preparing a second bacteriotherapy composition by obtaining a second donor fecal sample from a second donor, homogenizing the second donor fecal sample with at least one cryoprotectant, and then filtering;
storing the first bacteriotherapy composition and the second bacteriotherapy composition in a temperature controlled storage bank;
wherein the first bacteriotherapy composition includes a first dietary characteristic of the first donor;
wherein the second bacteriotherapy composition includes a second dietary characteristic of the second donor different from the first dietary characteristic of the first donor;
wherein the first dietary characteristic and the second dietary characteristic of the human donor are a human donor geographic consumption region, a human donor diet, a human donor religion, or combinations thereof and are configured to be matched to a patient having a digestive disorder such that a gut microbiota of the donor and a gut microbiota of the patient are similar; and
administering either the first bacteriotherapy composition or the second bacteriotherapy composition to the patient by oral, naso-gastric, antegrade gastrointestinal, retrograde gastrointestinal, endoscopic, or enemic administration.
2. The method of claim 1 , wherein prior to obtaining the first donor fecal sample, the health of the first donor is pre-screened to exclude an unhealthy donor.
3. The method of claim 2 , wherein pre-screening the health of the first donor comprises testing blood and fecal samples from the first donor for at least one of a parasite, a pathogen, a disease, or an unhealthy condition of the first donor.
4. The method of claim 1 , further comprising freezing the first and second bacteriotherapy compositions, storing the first and second bacteriotherapy compositions in the temperature controlled storage bank, and thawing either the first or second bacteriotherapy composition prior to administration to the patient.
5. The method of claim 1 , wherein the first and second bacteriotherapy compositions contains a viable population of micro biota.
6. The method of claim 1 , further comprising forming the first bacteriotherapy composition into a first pill and forming the second bacteriotherapy composition into a second pill and wherein administering either the first bacteriotherapy composition or the second bacteriotherapy composition includes administering either the first pill or the second pill.
