Preliminary evaluation of probiotic effects on gastrointestinal signs in dogs with multicentric lymphoma undergoing multi-agent chemotherapy: A randomised, placebo-controlled study.
Background: Gastrointestinal (GI) toxicity is a major dose-limiting factor in dogs undergoing chemotherapy. A proposed mechanism of GI toxicity includes chemotherapy-driven GI dysbiosis. This study was designed to determine the effects of probiotic administration on GI side-effects in dogs receiving multi-agent chemotherapy.
Methods: Ten client-owned dogs with multicentric lymphoma were enrolled in a prospective, randomised, placebo-controlled single-blinded study. On the first day of the cyclophosphamide doxorubicin vincristine prednisone (CHOP)-based chemotherapy protocol, dogs were randomised to receive either daily oral probiotic at a dose of 200 × 109 cfu/10 kg (n = 5) or daily oral placebo (n = 5). Complete blood count, faecal score (FS), faecal microbiome analysis (qPCR) and adverse events scores were performed at baseline and on the day of each subsequent chemotherapy dose, as well as 3 days after doxorubicin (days 0, 7, 14, 21, 24 and 28).
Results: Overall, 40% of dogs had an abnormal GI microbiome at baseline, specifically decreased faecal C. hiranonis and Fusobacterium abundances. Dogs receiving probiotics had increased faecal Streptococcus (p = 0.02) and E. coli. (p = 0.01). No dogs receiving probiotics experienced diarrhoea (FS ≥ 3.5) compared to four of five receiving placebo. (F 2.895; p = 0.13).
Conclusion: GI microbiome dysbiosis was common in this group of dogs with multicentric lymphoma. Probiotics were well-tolerated, with no negative side effects. Further studies are needed to explore broader microbiome and metabolome changes, as well as clinical benefit.
