Effects of Probiotics on Liver Diseases: Current In Vitro and In Vivo Studies

Area of Science:

• Hepatology and Microbiology
• Immunology and Gastroenterology

Background:

• Liver diseases cause millions of deaths globally, with limited treatment options and low transplant rates.
• The gut-liver axis and immune system interactions are critical in liver disease pathogenesis.
• Probiotics present a non-toxic, biosafe alternative to conventional treatments for liver conditions.

Purpose of the Study:

• To review preclinical and clinical evidence on probiotic administration for various liver diseases.
• To highlight the role of probiotics in modulating gut microbiota and immune responses relevant to liver health.
• To assess the therapeutic potential of probiotics and their metabolites in liver disease management.

Main Methods:

• Systematic review of existing preclinical and clinical studies.
• Analysis of data on probiotic effects on liver disease models and patient outcomes.
• Evaluation of probiotic mechanisms, including microbiota modulation and immune stimulation.

Main Results:

• Probiotics demonstrate beneficial effects on gut microbiota composition and function.
• Evidence suggests probiotics can modulate immune responses and reduce liver inflammation.
• Probiotic metabolites, such as bacteriocins, show antimicrobial activity against pathogens relevant to liver disease.

Conclusions:

• Probiotic administration shows promise as a therapeutic strategy for preventing and treating liver diseases.
• Further research is warranted to elucidate optimal probiotic strains and dosages for specific liver conditions.
• Probiotics represent a viable complementary approach to conventional therapies for liver disease management.
