Fecal transplant treatment for auto-brewery (gut fermentation) syndrome

Fecal microbiota transplantation for auto-brewery syndrome

['FUNDING_R21'] · UNIVERSITY OF CALIFORNIA, SAN DIEGO · NIH-11197592

This project gives capsule fecal microbiota transplants to adults with auto-brewery syndrome to try to stop their gut from producing alcohol and causing unexplained intoxication.

What this research studies

You will provide stool samples so researchers can compare your gut bacteria to household partners because lab tests showed patient samples made more ethanol and antibiotics could stop that production. If eligible, you may receive oral capsules of fecal microbiota transplantation (FMT) intended to replace the ethanol-producing microbes in your gut. The team will track your symptoms, breath or blood alcohol levels, and stool over time and monitor for side effects. The goal is to see whether FMT can reduce or stop inebriation episodes and be safe and tolerable.

Who could benefit from this research

Good fit: Adults aged 21 and older with suspected or diagnosed auto-brewery syndrome who have recurrent unexplained intoxication episodes and can provide stool samples and attend follow-up visits.

Not a fit: People whose symptoms are due to ongoing drinking rather than gut fermentation, pregnant women, or those with severe immune compromise may not be eligible or likely to benefit.

Why it matters

Potential benefit: If successful, FMT could reduce or stop ABS flares and lessen the social, legal, and safety consequences of unexplained intoxication.

How similar studies have performed: FMT is an established cure for C. difficile and the investigators report one ABS patient who achieved remission after capsule FMT, but use of FMT for ABS is experimental with very limited published data.
