Pilot study suggests ways to widen access to fecal transplants for C. diff infections

24.04.2014

Using frozen stool from healthy, unrelated donors was safe and effective in treating patients with serious, relapsing diarrhea caused by Clostridium difficile, according to a new pilot study published in Clinical Infectious Diseases and available online.

Known as fecal microbiota transplantation, the treatment was equally effective whether given via a colonoscope or a nasogastric tube. The findings suggest approaches that may make this promising treatment more readily available to patients.

A growing concern, C. difficile causes 250,000 infections requiring hospitalization and 14,000 deaths in the U.S. each year, according to the Centers for Disease Control and Prevention. Infection incidence has tripled in the last 15 years and is responsible for at least $1 billion in excess U.S. medical costs per year.

In an initial feasibility study, Ilan Youngster, MD, and colleagues at Massachusetts General Hospital (MGH) treated 20 patients suffering from repeated episodes of C. difficile infection with fecal microbiota transplantation, which helps restore the normal balance of bacteria in the affected person's gut. Fourteen of the patients were cured after one administration of donated stool. Of the remaining six patients, five received a second administration, and four were cured, for an overall cure rate of 90 percent.

Unlike previous studies, which used fresh stools from donors, the team at MGH worked with frozen material from unrelated donors who had been recruited and screened well ahead of time, a "banking" approach that may help overcome current treatment barriers.

"Establishing a repository of prescreened frozen donor stools could make this treatment available for a wider population," the authors noted, as donor recruitment and screening can be lengthy and costly. The Food and Drug Administration is currently determining how it will regulate fecal microbiota transplantation, including what steps clinicians must take to provide it to patients.

For their first administration, patients were assigned to one of two delivery methods, using either a colonoscope or a nasogastric tube, inserted in the nose and down into the stomach. Both appeared to be equally effective. Patients who required a second infusion were allowed to choose between the two methods, and all five chose the nasogastric tube.

"Colonoscopy is a significant procedure requiring sedation," said Elizabeth L. Hohmann, MD, of MGH and a study co-author, while the nasogastric tube method "is an outpatient office procedure."

The study's findings suggest the latter would be a "cost-effective, upper gastrointestinal route" for transplantation, Dr. Hohmann said, particularly for elderly or debilitated patients who may not tolerate a colonoscopy. The researchers are now studying placing the donated material into a frozen capsule, which patients would take orally.

Fast Facts:

1. A significant cause of life-threatening diarrhea, Clostridium difficile is responsible for 250,000 infections requiring hospitalization and 14,000 deaths in the U.S. each year. Relapsing infections are a serious problem.

2. This initial feasibility study found that using frozen stool from healthy, unrelated donors was safe and effective in treating a small group of patients with relapsing C. difficile infections, with an overall cure rate of 90 percent.

3. The treatment, known as fecal microbiota transplantation, appeared to be equally effective whether given via a colonoscope or a nasogastric tube.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
