Clostridioides difficile (C. diff) infection, one of the most common healthcare-acquired infection in the United States, could be treated with fecal transplantation.

"Twenty five years ago C. diff infections were easier to manage and often resolved with discontinuation of the initiating antibiotic," says Robert Orenstein, DO, an infectious disease specialist at Mayo Clinic and lead author on this article. "However, these infections have become increasingly common and pernicious." Read More..





The standard and FDA-approved treatment for C. diff is a course of oral vancomycin, an antibiotic. However, even the medications used to eliminate C. diff can perpetuate the infection by killing off beneficial microbes. Newer antibiotics that more specifically target C. diff have been developed but they can be prohibitively expensive, according to Dr. Orenstein.
"Think of your gut as a forest and C. diff as a weed," says Dr. Orenstein. "In a thriving forest, weeds barely get a foothold. But if you burn the forest down, the weeds are going to flourish."
Unlike antibiotics, which are destructive by definition, fecal transplants or microbial replacement therapies, repopulate the gut with a diverse group of microbes that may block the C. diff’s spore from germinating and propagating disease via its toxins. Transplants have several delivery methods, including enemas, capsules and direct instillation, to replace the diverse flora that maintain health and improve metabolism.
Currently, there are no FDA-approved fecal transplant products and performing fecal transplants is considered an investigational procedure. Dr. Orenstein notes there are several companies with products in Phase 3 clinical trials that could come to market as early as 2020.

C. diff is common in healthcare settings and public spaces and rarely causes problems in people with healthy gut microbiota and immune systems, according to researchers. However, people who are already ill and taking antibiotics, chemotherapy, or proton pump inhibitors--which all greatly disrupt the gut ecosystem--are at risk. Elderly patients are especially vulnerable.
"One of the most effective things physicians can do is become more responsible with antibiotic prescriptions," says Dr. Orenstein. "That means only prescribing when they are clearly indicated, not for colds or viral sinus infections. We also must be especially judicious with elderly patients."
