Effects of Synbiotic Administration on Gut Microbiome and Fecal Bile Acids in Dogs with Chronic Hepatobiliary Disease: A Randomized Case–Control Study
Abstract
Simple Summary Intestinal microbiome dysbiosis in human patients with chronic liver disease is known to influence disease progression. Several studies show benefits from administering probiotics/prebiotics. Similar intestinal dysbiosis was identified in dogs with chronic liver disease, but clinical trials evaluating the benefits of gut microbiome modulation in these patients are lacking. In the study, 32 dogs with chronic hepatobiliary disease were divided into two groups: one treated with a probiotics/prebiotics complex for 4–6 weeks and untreated control group. All dogs underwent clinical evaluation, complete anamnesis, bloodwork, abdominal ultrasound, fecal bile acids, and gut microbiome evaluation. Treated dogs showed a significant reduction in biochemical markers of liver injury and resolution of gastrointestinal signs compared to the control group. Some qualitative modifications of the gut microbiome were observed, but no significant changes in the fecal bile acids profile were detected in association with the probiotics/prebiotics administration. Abstract Alteration in the gut microbiome in human patients with chronic liver disease is a well-known pathophysiological mechanism. Therefore, it represents both a diagnostic and therapeutical target. Intestinal dysbiosis has also been identified in dogs with chronic liver disease, but clinical trials evaluating the effectiveness of synbiotic administration are lacking. Thirty-two dogs with chronic hepatobiliary disease were…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
