Probiotics, when considered in clinical practice, have traditionally been used for prophylaxis; however, there is growing data suggesting treatment benefits in numerous disease states. In this review, we focus on probiotics as treatment for and prevention of several acute and chronic infectious processes including Helicobacter pylori, Clostridium difficile, necrotizing enterocolitis, ventilator-associated pneumonia, vancomycin-resistant enterococci, and nonalcoholic fatty liver disease. It is inaccurate to generalize findings observed in a single probiotic species to all probiotics. This reasoning is due to the variability of colonizing abilities of native intestinal floras, probiotic or otherwise, secondary to different combinations, doses, and duration of treatments. Given these limitations, multiple animal and human studies have shown anti-inflammatory and selective antimicrobial effects of specific probiotics. Some studies suggest a role for probiotics as supplemental treatment, in combination with antibiotics, for the aforementioned disease processes. It is apparent from this review that the efficacy of probiotics is widely variable and multifaceted. More focused clinical and basic science research is necessary to better understand the treatment potential of various probiotics.

The gut microbiota has a significant role in human health and disease. Dysbiosis of the intestinal ecosystem contributes to the development of certain illnesses that can be reversed by favorable alterations by probiotics. The published literature was reviewed to identify scientific data showing a relationship between imbalance of gut bacteria and development of diseases that can be improved by biologic products. The medical conditions vary from infectious and antibiotic-associated diarrhea to obesity to chronic neurologic disorders. A number of controlled clinical trials have been performed to show important biologic effects in a number of these conditions through administration of prebiotics, probiotics, and synbiotics. Controlled clinical trials have identified a limited number of prebiotics, probiotic strains, and synbiotics that favorably prevent or improve the symptoms of various disorders including inflammatory bowel disease, irritable bowel syndrome, infectious and antibiotic-associated diarrhea, diabetes, nonalcoholic fatty liver disease, necrotizing enterocolitis in very low birth weight infants, and hepatic encephalopathy. Studies have shown that probiotics alter gut flora and lead to elaboration of flora metabolites that influence health through 1 of 3 general mechanisms: direct antimicrobial effects, enhancement of mucosal barrier integrity, and immune modulation. Restoring the balance of intestinal flora by introducing probiotics for disease prevention and treatment could be beneficial to human health. It is also clear that significant differences exist between different probiotic species. Metagenomics and metatranscriptomics together with bioinformatics have allowed us to study the cross-talk between the gut microbiota and the host, furthering insight into the next generation of biologic products.

The gut-liver axis involves complex interaction between the intestinal microbiome and the liver parenchyma. Probiotics are live microorganisms that are used in a variety of diseases. With currently only 2 randomized-controlled studies (one with Lactobacillus GG and the other with VSL #3), data are scarce to support the clinical effect of probiotic use in children with nonalcoholic fatty liver disease. There is evidence that probiotics decrease the risk of necrotizing enterocolitis and thereby reduce the prevalence of total parenteral nutrition-induced chronic liver disease. Probiotics are used with a few reported positive outcomes in patients with cystic fibrosis and familial hypercholesterolemia and may be promising in other liver conditions. Probiotics are generally safe and well tolerated in children, premature infants, and in patients after liver transplantation. Large, prospective, randomized clinical trials are needed to evaluate the benefit of probiotics in children with liver diseases.
