Compositions for fecal floral transplantation and methods for making and using them and devices for delivering them
In alternative embodiments, the invention provides compositions, e.g., formulations, used for gastric, gastrointestinal and/or colonic treatments or lavage, for inducing the purgation of a gastrointestinal (GI) tract, including a colon; and methods for making and using them. In alternative embodiments, compositions and methods of the invention are used for the stabilization, amelioration, treatment and/or prevention of constipation, for the treatment of abdominal pain, particularly non-specific abdominal pain, and diarrhea, including diarrhea caused by a drug side effect, a psychological condition, a disease or a condition such as Crohn's Disease, a poison, a toxin or an infection, e.g., a toxin-mediated traveler's diarrhea, or C. difficile or the pseudo-membranous colitis associated with this infection. In alternative embodiments, the invention provides pharmaceuticals and products (articles) of manufacture for delivering these compositions and formulations to an individual. The invention also provides devices for delivering a fecal material to a patient.
1. A method of manufacturing a stool composition comprising viable fecal bacteria from a stool of a healthy human donor, while limiting damage of the fecal bacteria during the manufacture and storage of the stool composition, the method comprising:
obtaining the stool from the healthy human donor;
storing the stool as non-frozen stool prior to processing the stool at a centralized flora bank;
processing the stool at the centralized flora bank by adding a cryoprotectant to the stool and homogenizing the stool and the cryoprotectant to form the stool composition; and
incorporating the stool composition into a container for storage and transport of the stool composition to a location distant from the centralized flora bank;
wherein the method preserves a number of viable bacteria from the stool sufficient to overcome a Clostridium difficile infection in a patient following administration of the stool composition to the patient.
2. The method of claim 1 , wherein the container comprises an oxygen-resistant plastic.
3. The method of claim 1 , wherein the container is made of aluminum-metallized polyethylene terephthalate polyester film.
4. The method of claim 1 , wherein the centralized flora bank comprises stools obtained from multiple healthy human donors.
5. The method of claim 1 , wherein the obtaining comprises collecting the stool in an anaerobic container and maintaining it at a temperature below room temperature but above freezing before storing.
6. The method of claim 1 , wherein the obtaining comprises collecting the stool in an anaerobic container comprising one or more substances that adsorb or absorb oxygen.
7. The method of claim 1 , wherein the cryoprotectant is glycerol.
8. The method of claim 1 , wherein the processing further comprises adding one or more antioxidants to the stool.
9. The method of claim 1 , wherein the processing comprises screening the stool for pathogens.
10. The method of claim 1 , wherein the container comprises a bag capable of holding fluids with one or more ports for entry or exit of fluids.
11. The method of claim 1 , wherein the transport is carried out in conditions below room temperature but above freezing.
12. The method of claim 1 , wherein the container is operably connected to a tubing equipment.
13. The method of claim 12 , wherein the container is attached to a pump with a one-way valve through the tubing equipment.
14. A method of manufacturing a standardized stool composition comprising viable fecal bacteria from a stool of a healthy human donor, while limiting damage of the fecal bacteria during the manufacture and storage of the standardized stool composition, the method comprising:
obtaining the stool from the healthy human donor;
storing the stool as non-frozen stool prior to processing the stool at a centralized flora bank;
processing the stool at the centralized flora bank by adding a cryoprotectant to the stool and homogenizing the stool and the cryoprotectant to form a standardized stool composition; and
incorporating the standardized stool composition into a container for storage and transport of the standardized stool composition to a location distant from the centralized flora bank;
wherein the standardized stool composition comprises sufficient viable bacteria from the stool to restore deficient fecal flora in a patient with a Clostridium difficile infection following administration of the standardized stool composition to the patient.
15. The method of claim 14 , wherein the container comprises an oxygen-resistant plastic.
16. The method of claim 14 , wherein the obtaining comprises collecting the stool in an anaerobic container and maintaining it at a temperature below room temperature but above freezing until it arrives at the centralized flora blank.
17. The method of claim 16 , wherein the anaerobic container comprises one or more substances that adsorb or absorb oxygen.
18. The method of claim 16 , wherein the anaerobic container is filled with nitrogen.
19. The method of claim 16 , wherein the anaerobic container is filled with a gas that will not damage fecal bacteria in the stool.
20. The method of claim 16 , wherein the anaerobic container is configured to not leak any gas.
