Emory transplant researchers have identified a control mechanism the immune system uses to tamp down chronic inflammation. The findings provide insight into how some people were able to stop taking immunosuppressive drugs after kidney transplant.
In addition, they may be important for a full understanding of how many drugs for cancer and autoimmune disorders (therapeutic antibodies) work. The results were published on January 14 in Immunity.

In February, the Infectious Diseases Society of America issued new guidelines for fighting Clostridium difficile, the hardy bacterium that can cause life-threatening diarrhea and whose dominance is sometimes a consequence of antibiotic treatment. The guidelines recommend for the first time that FMT (fecal microbiota transplant) be considered for individuals who have repeatedly failed standard antibiotics.
In a nice coincidence, Emory FMT specialists Colleen Kraft and Tanvi Dhere recently published a look at their clinical outcomes with C diff going back to 2012, in Clinical Infectious Diseases. They report 95 percent of patients (122/128) indicated they would undergo FMT again and 70 percent of the 122 said they would prefer FMT to antibiotics as initial treatment if they were to have a recurrence.

When facing a life-threatening infection, the “yuck factor” is a minor concern. Fecal microbiota transplant (FMT for short) has become an accepted treatment for recurrent Clostridium difficile infection, which can cause severe diarrhea and intestinal inflammation.
In a new video, Emory physicians Colleen Kraft and Tanvi Dhere explain how FMT restores microbial balance when someone’s internal garden has been disrupted.
C. difficile or “C diff” is a hardy bacterium that can barge into the intestines after another infection has been treated with antibiotics, when competition for real estate is low. In the last few years, doctors around the world have shown that FMT can resolve recurrent C diff infection better than antibiotics alone.
At Emory, Kraft and Dhere have performed almost 300 FMTs and report a 95 percent success rate when treating recurrent C diff. They have established a standard slate of stool donors, whose health is carefully screened.
Building on their experience with the procedure, Kraft and Dhere are studying whether FMT can head off other antibiotic-resistant infections besides C diff in kidney transplant patients. They have teamed up with infectious disease specialists Aneesh Mehta and Rachel Friedman-Moraco to conduct this study. Read more
The capsule study, published Monday in Journal of Infectious Diseases, represents an important step in moving away from fecal microbiota transplant as a treatment for C. difficile, says Colleen Kraft, MD, assistant professor of pathology and laboratory medicine and medicine (infectious diseases) at Emory University School of Medicine.
While this study involving 30 patients did not include a control group, the reported effectiveness of 96.7 percent compares favorably to published results on antibiotic treatment of C. difficile infection or fecal microbial transplant. Read more
