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 equally randomized into two groups: one treated with a synbiotic complex for 4-6 weeks (TG) and one untreated control group (CG). All dogs underwent clinical evaluation, complete anamnesis, bloodwork, abdominal ultrasound, fecal bile acids, and gut microbiome evaluation at T0-T1 (after 4-6 weeks). Treated dogs showed a significant reduction in ALT activity (p = 0.007) and clinical resolution of gastrointestinal signs (p = 0.026) compared to control dogs. The synbiotic treatment resulted in a lower increase in Enterobacteriaceae and Lachnospiraceae compared to the control group but did not affect the overall richness and number of bacterial species. No significant changes in fecal bile acids profile were detected with synbiotic administration. Further studies are needed to better evaluate the effectiveness of synbiotic administration in these patients and the metabolic pathways involved in determining the clinical and biochemical improvement.
