Efficacy of Probiotics and Smectite in Rats with Non-Alcoholic Fatty Liver Disease

Abstract

INTRODUCTION AND AIM: Today probiotics have been suggested as a treatment for the prevention of non-alcoholic fatty liver disease (NAFLD). Smectite is a natural silicate that binds to digestive mucous and has the ability to bind endo- and exotoxins. The present study was designed to determine whether probiotics plus smectite is superior to probiotic alone on the monosodium glutamate (MSG) induced NAFLD model in rats.

MATERIALS AND METHODS: We included 60 rats divided into 4 groups 15 animals in each. Rats of group I were intact. Newborns rats of groups II-IV were injected with MSG. The III (Symbiter) group received 2.5 ml/kg of multiprobiotic "Symbiter" containing concentrated biomass of 14 probiotic bacteria genera. The IV (Symbiter+Smectite) groups received "Symbiter Forte" combination of probiotic biomass with smectite gel (250 mg).

RESULTS: In both interventional groups reduction of total NAS score as compared to MSG-obesity was observed. Indeed similar values of steatosis score (0.93 ± 0.22 vs. 0.87 ± 0.16) in both treatment groups, we observed that lower total score for Symbiter+ Smectite are associated with more pronounced reduction of lobular inflammation (0.13 ± 0.09 vs. 0.33 ± 0.15) as compared to administration of probiotic alone. This data accompanied with significant reduction of IL-1 and restoration of IL-10 between these 2 groups.

CONCLUSIONS: Additional to alive probiotic administration of smectite gel due to his absorbent activity and mucus layer stabilization properties can impact on synergistic enhancement of single effect which manifested with reduction of lobular inflammation and at list partly steatohepatitis prevention.
