Objective: Various lines of evidence suggest that malfunctioning of the gut-liver axis contributes to hepatic damage of rodents and humans with nonalcoholic fatty liver disease. We evaluated the effects of short-term probiotic treatment in children with obesity-related liver disease who were noncompliant with lifestyle interventions.Patients and Methods: Twenty obese children (age 10.7 +/- 2.1 years) with persisting hypertransaminasemia and ultrasonographic (US) bright liver were enrolled in this double-blind, placebo-controlled pilot study. At baseline, patients underwent clinical and laboratory anthropometric evaluation, measurement of the US hepatorenal ratio, standard liver function tests, oral glucose tolerance test, serum tumor necrosis factor-alpha, the glucose hydrogen breath test, and evaluation of serum antibodies to antipeptidoglycan-polysaccharide polymers. After exclusion of causes of liver disease other than obesity, patients received either probiotic Lactobacillus rhamnosus strain GG (12 billion CFU/day) or placebo for 8 weeks.Results: Multivariate analysis after probiotic treatment revealed a significant decrease in alanine aminotransferase (average variation vs placebo P = 0.03) and in antipeptidoglycan-polysaccharide antibodies (average variation vs placebo P = 0.03) irrespective of changes in BMI z score and visceral fat. Tumor necrosis factor-alpha, and US bright liver parameters remained fairly stable.Conclusions: Probiotic L rhamnosus strain GG warrants consideration as a therapeutic tool to treat hypertransaminasemia in hepatopathic obese children noncompliant with lifestyle interventions.

Abstract

Objective: Various lines of evidence suggest that malfunctioning of the gut-liver axis contributes to hepatic damage of rodents and humans with nonalcoholic fatty liver disease. We evaluated the effects of short-term probiotic treatment in children with obesity-related liver disease who were noncompliant with lifestyle interventions.Patients and Methods: Twenty obese children (age 10.7 +/- 2.1 years) with persisting hypertransaminasemia and ultrasonographic (US) bright liver were enrolled in this double-blind, placebo-controlled pilot study. At baseline, patients underwent clinical and laboratory anthropometric evaluation, measurement of the US hepatorenal ratio, standard liver function tests, oral glucose tolerance test, serum tumor necrosis factor-alpha, the glucose hydrogen breath test, and evaluation of serum antibodies to antipeptidoglycan-polysaccharide polymers. After exclusion of causes of liver disease other than obesity, patients received either probiotic Lactobacillus rhamnosus strain GG (12 billion CFU/day) or placebo for 8 weeks.Results: Multivariate analysis after probiotic treatment revealed a significant decrease in alanine aminotransferase (average variation vs placebo P = 0.03) and in antipeptidoglycan-polysaccharide antibodies (average variation vs placebo P = 0.03) irrespective of changes in BMI z score and visceral fat. Tumor necrosis factor-alpha, and US bright liver parameters remained fairly stable.Conclusions: Probiotic L rhamnosus strain GG warrants consideration as a therapeutic tool to treat hypertransaminasemia in hepatopathic obese children noncompliant with lifestyle interventions.
