Plain language summary
Alcoholic liver disease (ALD) is a series of liver diseases caused by long-term heavy drinking. Lipid metabolism disorder often occurs in people with alcoholic liver injury. Treatment is mainly a combination of alcohol abstinence, improving nutrition, treating the liver injury, and preventing or reversing the progress of liver fibrosis or promoting liver regeneration. The aim of this study was to investigate the effect of Lactobacillus casei on lipid metabolism and intestinal microflora in patients with alcoholic liver injury. This study was a randomised, double-blind, placebo-controlled trial. A total of 181 ALD patients were recruited and randomly assigned to one of the three groups; low-dose group, high-dose group and positive control group (+ there was another group of 20 healthy people which served as normal control group). Results showed disorder of lipid metabolism, intestinal flora imbalance and inflammation in patients with alcoholic liver injury. Furthermore, after supplementation of Lactobacillus casei, there was a significant increase in the amount of Lactobacillus and Bifidobacterium. Authors conclude that Lactobacillus casei supplementation can improve lipid metabolism and regulate intestinal flora disorders in patients with alcoholic liver injury.
Abstract
BACKGROUND The present study aims to investigate the effect of Lactobacillus casei on lipid metabolism and intestinal microflora in patients with alcoholic liver injury. METHODS In a double-blind randomized controlled trial, 158 recruited alcoholic liver injury patients were randomized to three treatments for 60 days: low-dose group (LP, n = 58, 100 ml of Lactobacillus casei strain Shirota (LcS)), high-dose group (HP, n = 54, 200 ml of LcS), and positive control group (PC, n = 46, 100 ml of special drinks without active Lactobacillus casei). Another group of 20 healthy people was served as normal control group (NC). RESULTS The serum levels of TG and LDLC in the HP group were significantly decreased by 26.56% and 23.83%, respectively than those in the PC group (P < 0.05). After supplementation of Lactobacillus casei, there was a significant increase in the amount of Lactobacillus and Bifidobacterium when compared with the PC group (P < 0.05). CONCLUSIONS Supplementation of Lactobacillus casei can improve lipid metabolism and regulate intestinal flora disorders in patients with alcoholic liver injury.

Plain language summary
The World Health Organization (WHO) reported that acute respiratory infection (ARI) is the leading cause of death in children followed by diarrhoea and constipation. In Vietnam, despite many achievements in malnutrition prevention, the rate of malnutrition is elevated. Malnutrition results in ARI, diarrhoea, and physical and mental retardation in children The aim of this study was to investigate the effects of a probiotic fermented milk product containing Lactobacillus casei strain Shirota (LcS) on gastrointestinal symptoms, respiratory infections, and the nutrition status of children from Vietnam. This study was a community based, controlled open trial and it was conducted over a period of 18 weeks consisting of 2-week screening/pre-observational period; 12-week intervention period; and 4-week postintervention period. A total of 1036 children (518 children in the Control group and 518 children in the Probiotic group) were enrolled in this study. Results showed a significant reduction in the incidence of constipation and beneficial effects to prevent infectious diseases in Vietnamese children. Furthermore, while LcS did not affect the duration of diarrhoea, the incidence of diarrhoea tended to be improved after 12 weeks of intervention. Authors conclude that habitual consumption of fermented milk containing LcS prevented constipation and ARI in Vietnamese children, and it may be useful for treating diarrhoea and improving nutritional status, thus conferring remarkable health benefits to children in Vietnam.
Abstract
OBJECTIVES To evaluate the efficacy of fermented milk containing Lactobacillus casei strain Shirota (LcS) on the incidence of constipation, diarrhea, acute respiratory infections (ARI), and nutritional status of young Vietnamese children. METHODS A controlled field trial was conducted with 1003 children (3-5 years old) in Thanh Hoa province in Vietnam. The probiotic group (n = 510) consumed fermented milk 65 mL/day containing 108 CFU/mL of LcS for the 12-week intervention period, whereas the control group (n = 493) was not given any. The incidence of constipation, diarrhea, ARI, and anthropometry in children was determined at baseline, after 4, 8, and 12-week intervention, and after the 4-week follow-up period. RESULTS Probiotic drink decreased the incidence of constipation after the 12-week intervention period (12.0% vs. 32.0%, OR = 0.28 (95% CI: 0.21-0.40), p < 0.001), tended to decrease the incidence of diarrhea (4.9% vs. 7.9%, OR = 0.60 (95% CI: 0.35-1.01), p = 0.068), and prevented the occurrence of ARI (15.9% vs. 24.5%, OR = 0.58 (95% CI: 0.42-0.79), p < 0.001), when compared with the control group. In contrast, no probiotic effects were observed for the duration of diarrhea or ARI. Weight gain was higher in the probiotic group than in the control group after 4, 8, and 12-week intervention and after the 4-week follow-up period (p < 0.05). CONCLUSIONS Daily intake of fermented milk containing LcS strongly prevented the incidence of constipation and ARI in Vietnamese children. This study also revealed the potential effects of the use of a probiotic drink on diarrhea prevention as well as nutritional status improvement.
