This is a quote from Thomas Borody's study on Fecal microbiota Transplantation (FMT) in ME/CFS-
One thing to note about the Borody study is that they did
not use fecal microbiota transplantation on the ME/CFS patients.
Rather Borody implanted
cultured gut bacteria (Bacteroidetes, Clostridia, and E. coli) into the colon. He describes this as a transcolonoscopic infusion, which I think means infusing the bacteria at the far end of the colon (where it joins the small intestine).
So this difference might explain Borody's apparent higher success rate, compared to for example Dr Kenny De Meirleir, who
found fecal transplants were effective for ME/CFS, but the positive effects were only short-lived, lasting around 10 weeks (after which he says the bad bacteria would return).
You can get the full Borody study as a pdf
here, in which it explains that:
In recently presented work, 60 patients attended CDD (36 female, 24 males; average age 55 ± 11.5yrs) with Chronic Fatigue Syndrome. Of these, 52 had IBS in conjunction with their CFS and another 4 presented with constipation. All underwent bacteriotherapy for their CFS.
...
All patients received a single transcolonoscopic (TC) infusion of 300cc of anaerobic bacterial culture. Fifty-two of the 60 patients then underwent a single, rectal infusion the following day while 3/60 patients underwent two days of rectal infusions
Bacteriotherapy involves the infusion of a mixture of 13 non-pathogenic enteric bacteria (a combination of Bacteroidetes, Clostridia, and E. coli), in attempt to correct imbalances in the composition of the flora.
Faecal microbiota transplantation (FMT) offers an attractive alternative to bacteriotherapy as it enables the reintroduction of a complete, stable and 'healthy' bowel flora. Similar to bacteriotherapy, FMT involves the infusion (via colonoscopy or enema) of bacteria.
So it is clear that when Borody refers to bacteriotherapy, he does not mean fecal microbiota transplantation of stool from a donor, but infusion into the colon of bacterial species that have been cultured in the lab.
But no other study or treatment center has repeated these bacteriotherapy results to my knowledge, which makes me question the original Borody study. If this simple bacteriotherapy approach was really permanently curing nearly 60% of ME/CFS patients, I am sure it would have been adopted around the world.
It's possible that new regulations have now prevented the use of cultured bacterial infusions of species such as Bacteroidetes, Clostridia, and E. coli, because of the risk of infections or sepsis. Maybe that is the reason Borody's approach was not adopted?
At
Borody's own clinic, the Centre for Digestive Diseases in Australia, he does not appear offer bacteriotherapy or FMT treatment for ME/CFS. According to the
website, he treats ulcerative colitis and IBS with FMT, but not ME/CFS. So his study claims to have found an amazing cure for ME/CFS with IBS, but he is not offering this treatment at his clinic.
