Fecal Microbiota Transplantation
Though intended to be curative or even lifesaving, antibiotics can sometimes introduce a health threat. One is clostridium difficile (C. difficile), an aggressive intestinal bacteria that can cause a serious to dangerous infection. This occurs when antibiotic treatment clears the colon of the healthy bacteria that normally reside there and keep C. difficile at bay.
The expert gastroenterologists and infectious disease specialists at The University of Kansas Health System offer advanced treatment to fight C. difficile. Fecal microbiota transplantation (FMT) is an effective approach to reintroducing the beneficial bacteria that protect against infection.
Answers to your questions about FMT
Clostridium difficile (C. difficile) and fecal microbiota transplantation (FMT) can be difficult to understand. We answer some of the most frequently asked questions about the disease and treatment.
About C. difficile
C. difficile is a common bacterial infection and can be aggressive. It infects about 500,000 people in the United States every year and sends hundreds of thousands to the hospital. C. difficile can be fatal, causing 14,000 to 30,000 deaths annually.
Organisms normally present in the GI tract generally occupy the sites where C. difficile would attach and grow. When antibiotics wipe out helpful bacteria, C. difficile can take hold. When those who carry C. difficile fail to wash their hands well, they contaminate surfaces they touch. When others touch contaminated surfaces, they may inadvertently transfer the bacteria to their food or mouths.
Symptoms and risks
The symptoms of C. difficile include:
- Watery diarrhea three or more times a day for more than two days
- Abdominal pain
- Mild to moderate nausea
- Loss of appetite
In more serious cases, inflammation within the colon can be extensive, even cause bleeding and damage to the intestinal lining. Symptoms of severe infections include:
- Watery diarrhea as often as 15 times dailySevere abdominal pain and intestinal cramping
- Weight loss
Very severe cases can lead to dehydration, low blood pressure, kidney failure or bowel perforation.
Antibiotic use is the primary trigger of a C. difficile infection, especially when used for a long period of time or when a broad-spectrum antibiotic that kills a wide variety of bacteria has been prescribed.
Additional risk factors include:
- 65 years of age or older
- Recent abdominal surgery
- Existing intestinal issues, such as inflammatory bowel disease or colon cancer
- Weakened immune system due to chemotherapy, immunosuppression drugs or AIDS
- Previous C. difficile infection, especially recent
If you develop diarrhea within a few days of admission to or release from the hospital or within two months of taking an antibiotic or have three or more bouts of diarrhea in 24 hours, C. difficile could be responsible.
Diagnosis and treatment
There are several ways to diagnose and treat C. difficile.
The infection can be diagnosed by:
- Stool test or blood test
- Endoscopic examination
- CT scan
Treatment options include:
If you are already taking an antibiotic, your doctor may switch to a different one. Metronidazole, vancomycin and fidaxomicin are often chosen to combat stubborn C. difficile.
Fecal microbiota transplantation (FMT)
This is a procedure in which stool from a healthy donor is transferred into the colon of the patient with C. difficile. The healthy stool brings with it the healthy microorganisms lacking in the patient's GI tract.
These living microorganisms, including bacteria and yeasts, are similar to those that naturally inhabit the GI tract and can help fight C. difficile by competing for the space it occupies.
In severe cases, a surgeon may need to remove the infected or damaged part of the GI tract.
How does FMT work?
The human body is home to a microbiome, a living community of bacterial organisms that play important roles in processes such as nutrition and immunology.
In FMT, the bacterial community of a healthy donor is placed into the patient with C. difficile. The donor and sample are carefully screened. The healthy stool is transferred to the recipient through the upper GI tract (via prepared capsule or tube from the nostrils to the intestine) or the lower GI tract (via colonoscopy, sigmoidoscopy or enema).
Once transferred, the newly acquired healthy bacteria can begin fighting the dangerous C. difficile.
