Factors in an Auto-Brewery Syndrome group compared to an American Gut Project group: a case-control study

Area of Science:

• Gastroenterology
• Microbiome Research
• Internal Medicine

Background:

• Auto-Brewery Syndrome (ABS), or Gut Fermentation Syndrome, is a rare and underdiagnosed condition.
• Existing research on ABS is limited, with few studies comparing patient demographics, lifestyle, and diet to control groups.

Purpose of the Study:

• To identify differentiating factors in lifestyle, health, diet, and medical history between ABS patients and their household members compared to a larger general population.
• To generate hypotheses regarding potential comorbidities associated with ABS.

Main Methods:

• A case-control study was conducted involving 46 ABS patients and their household members.
• A survey was administered, and data were compared to a cohort of 11,297 American Gut Project (AGP) participants on 30 identical questions.
• Statistical analysis, including Rank Sum Tests, was employed to analyze the data.

Main Results:

• ABS patients and household members reported higher pet ownership, reduced sleep duration, and poorer bowel movement quality compared to AGP participants.
• The ABS group consumed more water, less alcohol, ate at home more frequently, and showed a greater aversion to sweets.
• A significantly higher prevalence of non-food allergies across all surveyed categories was observed in the ABS group.

Conclusions:

• Significant lifestyle, health, dietary, and medical history differences exist between ABS patients/household members and the general population.
• These observed differences suggest potential co-morbidities and areas for future research into Auto-Brewery Syndrome.
