Probiotics01:22

Probiotics

Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...

Diseases of the Liver and Gallbladder

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug binding...
Microbiota Modulation by Antibiotics01:21

Microbiota Modulation by Antibiotics

Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment01:08

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Summary

Probiotics may help manage chronic liver diseases by improving gut health. This review explores their role in preventing infections, aiding liver function, and treating conditions like cirrhosis and fatty liver disease.

Area of Science:

  • Gastroenterology and Hepatology
  • Microbiology
  • Internal Medicine

Background:

  • Chronic liver diseases are associated with gut dysbiosis.
  • Intestinal flora modulation via probiotics is a novel therapeutic approach.
  • Understanding the pathophysiologic basis is crucial for effective treatment.

Purpose of the Study:

  • To review the existing literature on probiotic use in chronic liver diseases.
  • To examine the pathophysiologic rationale for employing probiotics.
  • To assess the role of probiotics in specific liver disease complications.

Main Methods:

  • Literature review of studies on probiotics and liver disease.
  • Analysis of pathophysiologic mechanisms linking gut microbiota and liver health.

Related Experiment Videos

  • Examination of clinical evidence for probiotic efficacy.

    • Main Results:

    • Probiotics show potential in preventing infections in liver disease patients.
    • They may help manage the hyperdynamic circulatory state in cirrhosis.
    • Evidence suggests benefits for hepatic encephalopathy, liver function, and nonalcoholic fatty liver disease.

    Conclusions:

    • Probiotics represent a promising strategy for managing chronic liver diseases.
    • Further research is warranted to elucidate optimal probiotic strains and dosages.
    • Targeting intestinal flora offers a new avenue for liver disease therapeutics.
