CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of priority to United States Provisional Patent Application Serial No. 61/475,865 filed 15 April 2011, which is incorporated by reference herein in its entirety.
FIELD OF THE INVENTION
The present invention relates to pharmaceutical compositions and methods suitable for the treatment of intestinal disorders and chronic diseases associated with the presence of abnormal distribution of microflora in the gastrointestinal tract of a mammalian host.
BACKGROUND
All publications herein are incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference. The following description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
There are a large number of gastro-intestinal diseases that can be, at least in part, attributable to an imbalance, disruption, or abnormal distribution of microflora in the gastrointestinal tract of a mammalian host. These diseases include, but are not limited to, Clostridium difficile-associated diarrhea and colitis, insulin resistance, irritable bowel syndrome (IBS) or spastic colon, idiopathic ulcerative colitis, mucous colitis, collagenous colitis, Crohn's disease, inflammatory bowel disease in general, microscopic colitis, antibiotic-associated colitis, and idiopathic or simple constipation. Over the past few decades, several researchers have begun treating several of these diseases using a form of probiotics called fecal bacteriotherapy or fecal transfusion/transplant to help re-establish and/or rebalance the gut flora. (For a review see Borody, T.J. et al., "Bacteriotherapy using fecal flora: toying with human motions," J Clin Gastroenterol, 38: 475-83, 2004; McFarland, L. V. "Evidence-Based Review of Probiotics for Antibiotic- Associated Diarrhea." Anaerobe, 2009;15:271-280; Quigley, E. M. M. "Probiotics in Gastrointestinal Disorders." Hospital Practice. 2010;38: 15 pages.) In general, these researchers have met with great success. Recent studies have demonstrated that certain gut species are more prevalent or more conserved between individuals, thus constituting a phylogenetic core of gut flora. (Tap, J. et al., "Towards the human intestinal microbiota phylogenetic core," Environmental Microbiology, 11 : 2574-2584, 2009; which is hereby incorporated by reference in its entirety and especially for its teachings related to the phylogenetic core). This phylogenetic core of gut flora has been reported to include Faecalibacterium prausnitzii, Eubacterium rectale, Ruminococcus bromii, Alistipes putredinis, Subdoligranulum sp, Bacteroides vulgatus, Bacteroides uniformis rel, Parabacteroides distasonis, Bifidobacterium longum, Dorea formicigenerans, and Roseburia intestinalis. Tap et al., further reported that the phylogenetic core constituted bacteria from the phyla Firmicutes, Bacteroidetes, Actinobacteria, Proteobacteria and Verrumicrobia, in the proportions of 79.4%, 16.9%, 2.5%>, 1%>, and 0.1%>, respectively.
Fecal bacteriotherapy uses the complete normal human flora as a therapeutic probiotic mixture of living organisms. This type of bacteriotherapy has a longstanding history in animal health and has been used sporadically against chronic infections of the bowel. It involves infusion of bacterial flora acquired from the feces of a healthy donor to reverse the bacterial imbalance responsible for the recurring nature of the infection.
Although fecal bacteriotheraphy has had significant clinical success in treating gastrointestinal diseases, it has not been embraced by patients as a viable option. This is believed to be at least partly due to the thought of using a treatment where fecal matter is transplanted into the intestinal tract of a patient, wherein the fecal matter may or may not be from self. Furthermore, although all of the fecal bacteriotheraphy treatments screen for potential infectious or opportunistic microorganisms, errors occur and there have been a number of situations where a further infection was caused by the treatment, fecal bacteriotheraphy. Moreover, a disadvantage of many of the fecal bacteriotheraphy formulations is the poor shelf life of the formulations.
Therefore, a significant need exists in the art for improvements to fecal bacteriotheraphy, wherein patients will readily choose this sort of treatment as a viable option. This is because fecal matter is not being transfused, transferred, or transplanted into their intestinal tract, and the treatment comprises a predetermined set of gut flora that do not include any potential infectious or opportunistic microorganisms. Moreover, there is a need in the art for the treatment to have improved stability and increased delivery of viable gut flora. In particular, a need exists for providing stable gut flora compositions comprising bacterial strains that have previously been very difficult to store long-term or at room temperature.

Figure 1 shows the microbes and the relative frequencies of the microbes that can be utilized in the rapid recolonization deployment agent. DETAILED DESCRIPTION OF THE INVENTION
Certain embodiments disclosed herein relate to pharmaceutical compositions and methods of treatment, wherein the rapid recolonization of normal gut flora in a compromised intestinal tract is stimulated through introduction of microbial components and associated environmental modifiers that mimic those found in a normal, healthy individual. Through this introduction, normal (and even superior) intestinal health is restored and opportunistic infectious agents (e.g. Clostridium dificile, Vibrio cholerae, and species of Campylobacter) are suppressed. Further embodiments disclosed herein relate to novel pharmaceutical compositions suitable for the treatment of various disease states related to the presence of "abnormal" microflora in the gastrointestinal tract.
Certain embodiments disclosed herein relate to pharmaceutical compositions, devices and methods of treatment, involving a reconstitution of gut flora from healthy individuals, including the appropriate proportions of each individual microorganism. To that end, the microbial and other components used in the compositions, devices and methods may, in certain embodiments, be substantially similar to that which one would find in fecal matter used in fecal transplant procedures.
Further embodiments disclosed herein, relate to pharmaceutical compositions and methods of treatment, wherein the patients will readily choose this sort of treatment (rapid recolonization deployment agent) as a viable option. This is because fecal matter is not being transfused, transferred, or transplanted into their intestinal tract, and the treatment comprises a predetermined set of gut flora that do not include any potential infectious or opportunistic microorganisms
According to certain embodiments, the inventive rapid recolonization deployment agent can substitute for fecal transfusion and can contain cleaner, more stabilized, and more accurate intestinal and/or gut flora to help in re-establishing proper intestinal and/or gut flora.
According to certain embodiments, the rapid recolonization deployment agent can include microbial agents and associated elements in a shelf-stable form produced by culture and stabilized via freeze-dry process. According to further embodiments, upon use, the agent is rehydrated in sterile water and introduced through direct access to colon (enema, suppository, or capsule insertion). Certain embodiments herein relate to therapeutic compositions and methods of treatment for a subject by preventing or alleviating at least one symptom of a digestive associated condition or disease. For example, the therapeutic compositions and/or methods disclosed herein may be useful for treating or preventing one or more condition or disease selected from the group consisting of gastritis, peptic ulcer, duodenal ulcer, gastroesophageal reflux disease (GERD), acid reflux, eosinophilic esophagitis, inflammatory bowel disease (such as Crohn's disease), gastrointestinal cancer (e.g., stomach cancer, esophageal cancer, colon cancer gallbladder cancer, liver cancer, pancreatic cancer, colorectal cancer, anal cancer, and gastrointestinal stromal tumors), irritable bowel syndrome, infection or trauma to the gastrointestinal tract, including infection by H. pylori, Salmonella, Shigella, Staphylococcus, Campylobacter, Clostridium, Escherichia coli, Yersinia, Vibrio, Candida, Giardia, Entamoeba histolytica, rotavirus, noro virus, adenovirus and astro virus, inflammation in the gastrointestinal tract, ulcerative colitis, and others.
Symptoms of digestive conditions or disorders generally include pain, nausea, vomiting, diarrhea, dysentery, constipation, bloating, sore throat, laryngeal or respiratory irritation, oropharyngeal irritation, weight loss or weight gain, and the like.
According to certain embodiments, the rapid recolonization deployment agent can be used to suppress opportunistic intestinal infections (e.g., Vibrio cholerae, Campylobacter). According to further embodiments, the rapid recolonization deployment agent can be used as prophylactic support of gut flora during heavy antibiotic regimens or other therapies hostile to normal gut flora. According to still further embodiments, the rapid recolonization deployment agent can be used to reestablish normal gut performance in inflammatory processes or acute injury.
According to further embodiments, the rapid recolonization deployment agent can contain microbial agents and associated environmental and promotional elements. According to still further embodiments, the inventive rapid recolonization deployment agents are produced in a shelf-stabilized and/or room temperature stabilized formulation. This shelf- stabilized and/or room temperature stabilized formulation can be via freeze-drying.
According to still further embodiments, the rapid recolonization deployment agent can be introduced via direct access to the compromised gut (tube, enema, suppository or similar mechanism). According to certain embodiments, upon introduction of these microbial agents, viable colonies are re-established within the gut, displacing the opportunistic infectious agent(s). Importantly, this method of action has already been shown as a viable treatment option via direct fecal transplant procedures.

Certain embodiments provide for therapeutic compositions comprising the rapid recolonization deployment agent, a pharmaceutical composition or other therapeutic agent or a pharmaceutically acceptable salt or solvate thereof, and at least one pharmaceutical carrier or diluent. These pharmaceutical compositions can be used in the prophylaxis and treatment of the foregoing diseases or conditions and in therapies as mentioned above. Preferably, the carrier must be pharmaceutically acceptable and must be compatible with, i.e. not have a deleterious effect upon, the other ingredients in the composition. The carrier may be a solid or liquid and is preferably formulated as a unit dose formulation, for example, a tablet that may contain from 0.05 to 95% by weight of the active ingredient.
Administration Routes:
As one of ordinary skill in the art can readily appreciate, the intestinal tract is complex and composes many different environments beginning with the oral cavity and extending down through the stomach, small intestines and then finally the lower intestines and anus. Each one of these organs has a very different environment that can be challenging to deliver pharmaceutical compositions to and/or through to other sites in the intestinal tract. As such and as can be appreciated by one of ordinary skill in the art, many different methods to deliver pharmaceutical compositions may be useful when practicing this rapid recolonization deployment agent invention. In particular, possible administration routes include oral, sublingual, buccal, rectal, nasal, or insertion of implantable devices or materials (e.g., stents).
Most suitable means of administration for a particular subject will depend on the nature and severity of the disease or condition being treated or the nature of the therapy being used, as well as the nature of the therapeutic composition or additional therapeutic agent. For example, in certain diseases or conditions (e.g., Clostridium difficile-associated diarrhea and colitis and ulcerative colitis) the administration routes of treatment can be rectal administration. In certain embodiments, rectal administration is preferred. Further, in other diseases (e.g., Crohn's disease), where it could be necessary for the pharmaceutical composition to pass through the hostile and very acidic environment of the stomach to reach the appropriate cite of treatment, the administrative route can be oral using an appropriately coated pharmaceutical composition or can be direct treatment (e.g., via direct injection or via tubing) to the cite of the disease or condition. Alternatively, the pharmaceutical composition can be administered to the cite through tubing. This tubing can be introduced through an orifice, including but not limited to nasal, oral, or rectal. Moreover, certain diseases or conditions can have prolonged or intermittent states (e.g., insulin resistance and ulcerative colitis). In these diseases or conditions a method of treatment can have a system for extended treatment (e.g., a stent coated with the rapid recolonization microorganisms, a time-release device or capsule containing these organisms, and implantable pump containing these organisms). According to preferred embodiments, the route of administration for UC and other acute infections is via rectal administration. According to preferred embodiments, prophylactic treatment with the inventive rapid recolonization microorganisms to reduce the effect of antibiotics on gut flora is via oral administration.
In addition to the pharmaceutical compositions described herein, the pharmaceutical compositions can be associated with a type of scaffold (proteinaceous or otherwise), a type of stent coated with the pharmaceutical composition, time/controlled release capsules or devices, and/or an implantable pump. Types of proteinaceous scaffolds are described in Hey, T., et al., "Artificial, non-antibody binding proteins for pharmaceutical and industrial applications," Trends in Biotechnology. 2005;23:514-522.
Formulations suitable for rectal administration include gels, creams, lotions, aqueous or oily suspensions, dispersible powders or granules, emulsions, dissolvable solid materials, douches, and the like. The formulations are preferably provided as unit-dose suppositories comprising the active ingredient in one or more solid carriers forming the suppository base, for example, cocoa butter. Suitable carriers for such formulations include petroleum jelly, lanolin, polyethyleneglycols, alcohols, and combinations thereof. Alternatively, colonic washes with the rapid recolonization deployment agent of the present invention may be formulated for colonic or rectal administration.
Formulations suitable for oral administration may be provided as discrete units, such as tablets, capsules, cachets, syrups, elixirs, chewing gum, "lollipop" formulations, microemulsions, solutions, suspensions, lozenges, or gel-coated ampules, each containing a predetermined amount of the active compound; as powders or granules; as solutions or suspensions in aqueous or non-aqueous liquids; or as oil-in-water or water-in-oil emulsions.
Formulations suitable for transmucosal methods, such as by sublingual or buccal administration include lozenges patches, tablets, and the like comprising the active compound and, typically a flavored base, such as sugar and acacia or tragacanth and pastilles comprising the active compound in an inert base, such as gelatin and glycerine or sucrose acacia.
Formulations of the invention may be prepared by any suitable method, typically by uniformly and intimately admixing the pre-determined gut flora with liquids or finely divided solid carriers or both, in the required proportions and then, if necessary, shaping the resulting mixture into the desired shape. In addition, the pre-determined gut flora will be treated to prolong shelf-life, preferably the shelf-life of the pre-determined gut flora will be extended via freeze drying.
Furthermore, a tablet may be prepared by compressing an intimate mixture comprising a powder or granules of the active ingredient and one or more optional ingredients, such as a binder, lubricant, inert diluent, or surface active dispersing agent, or by molding an intimate mixture of powdered active ingredient of the present invention.
In addition to the ingredients specifically mentioned above, the formulations of the present invention may include other agents known to those skilled in the art, having regard for the type of formulation in issue. For example, formulations suitable for oral administration may include flavoring agents and formulations suitable for intranasal administration may include perfumes.
The therapeutic compositions of the invention can be administered by any conventional method available for use in conjunction with pharmaceutical drugs, either as individual therapeutic agents or in a combination of therapeutic agents.
The dosage administered will, of course, vary depending upon known factors, such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration; the age, health and weight of the recipient; the nature and extent of the symptoms; the kind of concurrent treatment; the frequency of treatment; and the effect desired. A daily dosage of active ingredient can be expected to be about 0.001 to 1000 milligrams (mg) per kilogram (kg) of body weight.
Dosage forms (compositions suitable for administration) contain from about 1 mg to about 500 mg of active ingredient per unit. In these pharmaceutical compositions, the active ingredient will ordinarily be present in an amount of about 0.5-95% weight based on the total weight of the composition.
Ointments, pastes, foams, occlusions, creams and gels also can contain excipients, such as starch, tragacanth, cellulose derivatives, silicones, bentonites, silica acid, and talc, or mixtures thereof. Powders and sprays also can contain excipients such as lactose, talc, silica acid, aluminum hydroxide, and calcium silicates, or mixtures of these substances.
Formulations suitable for rectal administration may be presented as suppositories by mixing with a variety of bases such as emulsifying bases or water-soluble bases. Formulations suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams, or spray formulas containing, in addition to the active ingredient, such carriers as are known in the art to be appropriate.
Suitable pharmaceutical carriers are described in Remington's Pharmaceutical Sciences, Mack Publishing Company, a standard reference text in this field.
The dose administered to a subject, especially an animal, particularly a human, in the context of the present invention should be sufficient to affect a therapeutic response in the animal over a reasonable time frame. One skilled in the art will recognize that dosage will depend upon a variety of factors including the condition of the animal, the body weight of the animal, as well as the condition being treated. A suitable dose is that which will result in a concentration of the therapeutic composition in a subject that is known to affect the desired response.
The size of the dose also will be determined by the route, timing and frequency of administration as well as the existence, nature, and extent of any adverse side effects that might accompany the administration of the therapeutic composition and the desired physiological effect.
It will be appreciated that the compounds of the combination may be administered:
(1) simultaneously by combination of the compounds in a co-formulation or (2) by alternation, i.e. delivering the compounds serially, sequentially, in parallel or simultaneously in separate pharmaceutical formulations. In alternation therapy, the delay in administering the second, and optionally a third active ingredient, should not be such as to lose the benefit of a synergistic therapeutic effect of the combination of the active ingredients. According to certain embodiments by either method of administration (1) or (2), ideally the combination should be administered to achieve the most efficacious results. In certain embodiments by either method of administration (1) or (2), ideally the combination should be administered to achieve peak plasma concentrations of each of the active ingredients.
It will be appreciated by those skilled in the art that the amount of active ingredients in the combinations of the invention required for use in treatment will vary according to a variety of factors, including the nature of the condition being treated and the age and condition of the patient, and will ultimately be at the discretion of the attending physician or health care practitioner. The factors to be considered include the route of administration and nature of the formulation, the animal's body weight, age and general condition and the nature and severity of the disease to be treated.

According to particular aspects, results from this in vitro analysis allows for the proper determination of the appropriate composition and amounts of each micro-flora used in the inventive rapid recolonization deployment agent and has substantial utility for treating Clostridium difficile infections, irritable bowel syndrome and inflammatory bowel disease, and insulin resistance. EXAMPLE 2
(The inventive rapid recolonization deployment agent is useful in the treatment of patients with Clostridium difficile -associated diarrhea and colitis)
Clostridium difficile-ass ociated diarrhea and colitis. Clostridia are anaerobic, spore- forming rods (bacilli). C. difficile is the most serious cause of antibiotic-associated diarrhea (AAD) and can lead to pseudomembranous colitis, a severe infection of the colon, often resulting from eradication of the normal gut flora by antibiotics. The C. difficile bacteria, which naturally reside in the body, become overpopulated. This overpopulation is harmful because the bacterium releases toxins that can cause bloating and diarrhea with abdominal pain, which can become severe. Latent symptoms often mimic some flu-like symptoms and can mimic disease flare in patients with inflammatory bowel disease-associated colitis. Clostridium difficile-associated diarrhea and colitis can be treated by discontinuing the antibiotics responsible for the initiation of the infection or by oral administration of metronidazole or vancomycin. However, relapses of C. difficile associated diarrhea have been reported in up to 20% of cases. In addition, there are very few effective treatments for chronic C. difficile infections.
Many studies have shown the efficacious use of fecal bacertiotherapy in treating chronic relapsing Clostridium difficile-associated diarrhea and colitis. (Rolfe RD, Helebian S, Finegold SM. Bacterial interference between Clostridium difficile and normal fecal flora. J Infect Dis. 1981;143:470-475; Borriello SP.

Neutralization of cytotoxic activity of Clostridium difficile with fecal flora. Arch Invest Med. 1987;18:315-317, all of which are hereby incorporated herein in their entirety and especially for their teachings concerning C. difficile.) In particular, research has shown that bowel flora can be re-established using homogenized human feces and that this feces has been shown to be consistently effective against C. difficile-associated diarrhea without having to resort to the use of vancomycin or metronidazole. (Borody TJ. Flora power— Fecal bacteria cure chronic C. difficile diarrhea.

As will be appreciated in the art, the appropriate dosage and timing of the inventive rapid recolonization deployment agent can be readily determined by one of ordinary skill in the art and can depend on the severity and extent of the infection. In addition, according to particular aspects, the number and repetition of treatments of the inventive rapid recolonization deployment agent can be readily determined by one of ordinary skill in the art and can depend on the severity and extent of the infection.
According to particular aspects, the effectiveness of the inventive rapid recolonization deployment agent can be followed using certain outcome measures of the C. difficile infection. These outcome measures can include: clinical improvement of the patient, change in certain markers of infection (e.g., the absence of C. difficile and its toxin post-infusion and the restoration of short-chain fatty acid profiles and other microflora-associated biochemical characteristics), changes in the mucosal imaging and histology of the intestines.

(The inventive rapid recolonization deployment agent is useful in the treatment of patients with inflammatory conditions and diseases of the digestive tract (e.g., irritable bowel syndrome and inflammatory bowel disease (e.g., Crohn 's disease and ulcerative colitis))
Inflammatory bowel disease. Inflammatory bowel disease (IBD) is a group of inflammatory conditions of the colon and small intestine. The major types of IBD are Crohn's disease (CD) and ulcerative colitis (UC) and the rising incidence of CD and high prevalence of UC are burdens to the community and the health system. The causes of IBD remain unknown, although accumulating evidence suggests that an excessive mucosal immune response to the enteric flora, or perhaps a specific infectious agent, in combination with genetic predisposition, may be responsible for the chronic inflammatory process.
Crohn 's disease. CD (aka, granulomatous colitis and regional enteritis) is an inflammatory disease that can affect any part of the gastrointestinal tract from mouth to anus, causing a wide variety of symptoms (e.g., abdominal pain, diarrhea (which may be bloody), vomiting, or weight loss, but may also cause complications outside of the gastrointestinal tract such as skin rashes, arthritis and inflammation of the eye. More specifically, CD is an autoimmune disease, caused by the immune system's attacking the gastrointestinal tract and producing inflammation in the gastrointestinal tract.
Interestingly, recent studies have indicated that the gut constituents differ between healthy individuals and individuals suffering from CD. Qin J. et al., (2010) "A human gut microbial gene catalogue established by metagenomic sequencing." Nature 464, 59-65 which is hereby incorporated by reference in its entirety). In particular, certain studies have shown an increase in C. difficile and E. faecalis and a decrease in F. prausnitzii, C. leptum, and R. albus in CD patients compared to healthy individuals. Sokol, H. et al, "Specificities of the fecal microbiota in inflammatory bowel disease," IBD 12:106-111, 2006 (which is hereby incorporated by reference in its entirety).
Ulcerative colitis. UC is a form of colitis, a disease of the intestine, specifically the large intestine or colon that includes characteristic ulcers, or open sores, in the colon. The main symptom of active disease is usually constant diarrhea mixed with blood. UC is an intermittent disease, with periods of exacerbated symptoms, and periods that are relatively symptom-free. Although the symptoms of ulcerative colitis can sometimes diminish without any treatment, the disease usually requires treatment to be relatively symptom-free. UC occurs in 35-100 people for every 100,000 in the United States, and it is more prevalent in northern countries of the world, as well as in northern areas of individual countries or other regions. Although UC has no known cause, there is a presumed genetic component to susceptibility. UC can be triggered in a susceptible person by environmental factors. Current treatment for UC includes: anti-inflammatory drugs, immunosuppression, and biological therapy targeting specific components of the immune response. Surgery to remove part of or the entire colon, colectomy, is conducted occasionally.
Interestingly, recent studies have indicated that the gut constituents differ between healthy individuals and individuals suffering from UC, wherein higher or lower percentages of certain microorganisms can be found. Qin J. et al., (2010) "A human gut microbial gene catalogue established by metagenomic sequencing." Nature 464, 59-65 (which is hereby incorporated by reference in its entirety).
Fecal bacteriotherapy has been used to recolonize the colon of individuals suffering with CD and/or UC with bacteria from a healthy bowel. There have been several reported cases of patients who have remained in remission for up to 13 years. Borody TJ, Warren EF, Leis S, Surace R, Ashman O (2003). "Treatment of ulcerative colitis using fecal bacteriotherapy". J. Clin. Gastroenterol. 37 (1): 42-7 and Borody TJ, Warren EF, Leis SM, Surace R, Ashman O, Siarakas S (2004). "Bacteriotherapy using fecal flora: toying with human motions". J. Clin. Gastroenterol. 38 (6): 475-83.
Irritable bowel syndrome (IBS). Irritable bowel syndrome (IBS) (aka, spastic colon) encompasses a variety of diseases causing discomfort in the gastro-intestinal tract (e.g., chronic abdominal pain, discomfort, bloating, altered bowel habits). Diarrhea or constipation may predominate, or they may alternate (classified as IBS-D, IBS-C or IBS-A, respectively). IBS may begin after an infection (post-infectious, IBS-PI) or a stressful life event. Significantly, there is no cure for IBS, but there are treatments which attempt to relieve symptoms (e.g., dietary adjustments, medication and psychological interventions). People with IBS commonly have gastroesophageal reflux.
The etiology of IBS is unknown although there is some evidence to suggest that a disturbance in the normal gut flora could be responsible for the onset and persistence of symptoms. (T.J. Borody, et al., "Bacteriotherapy using fecal flora: toying with human motions," J Clin Gastroenterol, 38: 475-83, 2004. King TS, Elia M, Hunter JO. "Abnormal colonic fermentation in irritable bowel syndrome." Lancet. 1998;352: 1187-1189. Pimental M, Chow EJ, Lin HC. "Eradication of small intestinal bacterial overgrowth reduces symptoms of irritable bowel syndrome." Am J Gastroenterol. 2000;95:3505-3506, all of which are incorporated by reference in their entirety, especially for their teachings concerning IBS and disruption of normal gut flora). Currently, treatment of IBS is managing the systems and often is unsatisfactory. Fecal transfusion can be used to remodel the composition of fecal flora in patients suffering form IBS with gut flora from healthy individuals seems a logical treatment option considering the tentative link between a disturbance in the normal gut flora and IBS. Some studies have suggested that the administration of probiotics both singly or in combination has shown some benefit in alleviating IBS symptoms, including pain and impair bowel function.

EXAMPLE 4
(The inventive rapid recolonization deployment agent is useful in the treatment of patients with insulin resistance and/or diabetes)
Insulin resistance. Insulin resistance or metabolic syndrome is a physiological condition where the hormone, insulin, becomes less effective at lowering blood sugars. The resulting increase in blood glucose may raise levels outside the normal range and cause adverse health effects. Certain cell types such as fat and muscle cells require insulin to absorb glucose. When these cells fail to respond adequately to circulating insulin, blood glucose levels rise. In addition, the liver helps regulate glucose levels by reducing its secretion of glucose in the presence of insulin. In individuals with insulin resistance glucose from their liver is not reduced due to the presence of insulin, thus allowing higher serum levels of glucose to exist. Moreover, other functions of insulin can also be affected. For example, insulin resistance in fat cells reduces the normal effects of insulin on lipids and results in reduced uptake of circulating lipids and increased hydrolysis of stored triglycerides. Increased mobilization of stored lipids in these cells elevates free fatty acids in the serum. Elevated blood fatty-acid concentrations (associated with insulin resistance and diabetes mellitus Type 2), reduces muscle glucose uptake, and increases liver glucose production which contribute further to elevated serum glucose levels. High plasma levels of insulin and glucose due to insulin resistance are a major component of the metabolic syndrome.
Recently, a group from the Academic Medical Center in Amsterdam has shown significant improvement in the insulin sensitivity of obese patients with metabolic syndrome using fecal transplants from donors who were healthy and thin. (Fiore, "Fecal Transplant Flushes Insulin Resistance", Medpage Today, Sept. 22, 2010, www.medpagetoday.com, citing to results discussed in Vrieze A, et al, "Metabolic effects of transplanting gut microbiota from lean donors to subjects with metabolic syndrome" European Association of the Study of Diabetes 2010; Abstract 90, which is hereby incorporated by reference in its entirety and especially for its teachings related to fecal transplants and insulin resistance). These researchers reported that after approximately six weeks, the peripheral insulin sensitivity of the eighteen patients receiving the fecal transplant from the thin donors had improved significantly when compared to those patients who had a fecal transplant from themselves. In addition, the report stated that animal studies confirmed the link between gut microbial flora and obesity. In particular, bacteria from the feces of either obese or lean mice were given to animals. These treated animals then either had a significant increase in total body fat or were leaner according to the mouse body type that from which the bacteria were collected. Thus, there are significant data to support fecal transplants having utility in treating obesity and/or insulin resistance.
