Abstract
 
Background
 
Although the etiology of idiopathic ulcerative colitis (UC) remains poorly understood, the intestinal flora is suspected to play an important role. Specific, consistent abnormalities in flora composition peculiar to UC have not yet been described, however Clostridium difficile colitis has been cured by the infusion of human fecal flora into the colon. This approach may also be applicable to the treatment of UC on the basis of restoration of flora imbalances.
 
Goal 
 
To observe the clinical, colonoscopic and histologic effects of human probiotic infusions (HPI) in 6 selected patients with UC.
 
Case Reports
 
Six patients (3 men and 3 women aged 25-53 years) with UC for less than 5 years were treated with HPI. All patients had suffered severe, recurrent symptoms and UC had been confirmed on colonoscopy and histology. Fecal flora donors were healthy adults who were extensively screened for parasites and bacterial pathogens. Patients were prepared with antibiotics and oral polyethylene glycol lavage. Fecal suspensions were administered as retention enemas within 10 minutes of preparation and the process repeated daily for 5 days. By 1 week post-HPI some symptoms of UC had improved. Complete reversal of symptoms was achieved in all patients by 4 months post-HPI, by which time all other UC medications had been ceased. At 1 to 13 years post-HPI and without any UC medication, there was no clinical, colonoscopic, or histologic evidence of UC in any patient.
 
Conclusions
 
Colonic infusion of donor human intestinal flora can reverse UC in selected patients. These anecdotal results support the concept of abnormal bowel flora or even a specific, albeit unidentified, bacterial pathogen causing UC.

Abstract
 
BACKGROUND:
 
Clinical observations and experimental colitis models have indicated the importance of intestinal bacteria in the etiology of ulcerative colitis (UC), but a causative bacterial agent has not been identified.
 
AIM:
 
To determine how intestinal bacteria are associated with UC, fecal microbiota and other components were compared for UC patients and healthy adults.
 
METHODS:
 
Fresh feces were collected from 48 UC patients. Fecal microbiota were analyzed by use of terminal-restriction fragment length polymorphism (T-RFLP), real-time PCR, and culture. The concentrations of organic acids, indole, and ammonia, and pH and moisture, which are indicators of the intestinal environment, were measured and compared with healthy control data.
 
RESULTS:
 
T-RFLP data divided the UC patients into four clusters; one cluster was obtained for healthy subjects. The diversity of fecal microbiota was significantly lower in UC patients. There were significantly fewer Bacteroides and Clostridium subcluster XIVab, and the amount of Enterococcus was higher in UC patients than in healthy subjects. The fecal concentration of organic acids was significantly lower in UC patients who were in remission.
 
CONCLUSION:
 
UC patients have imbalances in the intestinal environment-less diversity of fecal microbiota, lower levels of major anaerobic bacteria (Bacteroides and Clostridium subcluster XIVab), and a lower concentration of organic acids.

Clinics and Doctors Who Perform Fecal Microbiota Transplantation

We are compiling a list of doctors and hospitals around the world who have performed fecal microbiota transplants - the list will grow as more doctors start to use this procedure on their ailing patients. We would love your help in compiling this list, so a comment with a name of a doctor/physician/medical professional and any information you can give would be very much appreciated! Please don't try this procedure without qualified medical guidance and advice. It is essential that fecal doners be screened for various diseases including some which are contageous. This is why a list of doctors who are familiar with the procedure is important, so that those of you who feel fecal microbiota transplantation could be beneficial to you can seek out appropriate medical advice. Doctors from around the world are listed below: Australia Professor Thomas Borody , Centre For Digestive Diseases Five Dock, Sydney USA Dr Lawrence J Brandt Montefi...

"Jake's" Widespread Crohn's Disease Gone Thanks To FMT! 20 November 2013

It's been a while since I posted about my son "Jake".  For those who haven't read his story, here is the link   http://www.fecalmicrobiotatransplant.com/2013/07/crohns-disease-fmt.html  . He has been off medication (Imuran) for nine months now and looks and feels well.  Unfortunately his cousin who was his donor became unsuitable to donate in mid August due to picking up a parasite, so Jake has gone since then without any FMT . Today he had a colonoscopy and endoscopy and we were thrilled with the news.  There is no sign of Crohn's Disease anywhere - not in his intestines, not in his terminal ileum and not in his duodenum!!! In fact, Professor Borody said there was no scarring or ulceration or any indication that the disease had ever existed.  It was all perfect, healthy and inflammation-free.  When he was first diagnosed with Crohn's three years ago it was very widespread.  I am sure that anyone ...

Crohn's Disease, Acne and Fecal Microbiota Transplant In Teenager - Remission Without Medication! 27 July 2013

I have hesitated in sharing my son's story with Crohn's Disease and the success we have had with FMT (fecal microbiota transplantation) until now because I didn't want to do so prematurely. My son is 15 years old.  To protect his privacy, I will call him Jake, although that is not his real name :-). Jake was diagnosed with Crohn's Disease a few days before his 13th birthday.  It was widespread ulceration, inflammation and infection throughout his duodenum, terminal ileum, ascending colon, descending colon and rectum.  It was a "gut-wrenching" time for me as a mother to an only child, especially after being told how very serious this disease is, how extensively he had it, that he would have it for the rest of his life, and probably do poorly in the long-term because he was so young at diagnosis.  I was worried sick with the long term consequences of my son taking immune-suppressive drugs (in his case, Imuran) - on the other hand I was terrified of the c...
