Insights

Antituberculosis drug-induced hepatotoxicity (DIH) can harm patients. This study identified key molecular targets and pathways, revealing oxidative stress and apoptosis as mechanisms, offering insights for hepatoprotective strategies.

Area of Science:

  • Toxicology
  • Molecular Biology
  • Pharmacology

Background:

  • Drug-induced hepatotoxicity (DIH) is a significant adverse effect of antituberculosis (anti-TB) therapy.
  • DIH often leads to treatment interruption and adverse patient outcomes.

Purpose of the Study:

  • To elucidate the molecular mechanisms underlying anti-TB drug-induced hepatotoxicity.
  • To identify key molecular targets and signaling pathways involved in DIH.

Main Methods:

  • Integrated network toxicology, molecular docking, and in vivo experiments.
  • Analyzed drug-disease intersection-target interactions and pathway enrichment.
  • Assessed binding affinity of anti-TB drugs to hub targets and validated mRNA expression in vivo.

Main Results:

  • Identified NFE2L2, NFKB1, MAP2K1, MAPK14, IGF1R, and GSK3B as potential key targets for DIH.
  • Highlighted oxidative stress, apoptosis, and lipid accumulation as underlying mechanisms.
  • Validated changes in mRNA expression of core targets through in vivo experiments.

Conclusions:

  • Provided a deeper understanding of the molecular basis of anti-TB drug-induced hepatotoxicity.
  • Suggested potential molecular targets for developing hepatoprotective strategies during tuberculosis treatment.

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...

Drug Distribution: Tissue Binding01:21

Drug Distribution: Tissue Binding

Upon entering the systemic circulation, drugs can distribute into the interstitial and intracellular fluid of various tissue cells. This distribution is facilitated by the binding of drugs to different cellular components within tissues, which may lead to drug accumulation in specific areas. Drugs bound to tissue components serve as reservoirs that release free drugs back into the system, prolonging the drug's overall action. However, this accumulation can also result in local toxicity.

Effect of Hepatic Disease on Pharmacokinetics: Active Drug, Metabolite and Fraction of Metabolized Drug

In pharmacotherapy, monitoring drug concentrations is paramount, especially for drugs whose therapeutic effects hinge on both the active compound and its metabolite. Hepatic impairment profoundly influences drug potency by altering liver function. If the drug is more potent than its metabolite, impaired liver function amplifies drug activity due to elevated drug concentration levels. Conversely, if the metabolite holds greater potency, diminished liver function diminishes drug activity by...

Therapeutic Drug Monitoring: Drug Analysis Methods

Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood or body tissues to tailor drug therapy effectively. This monitoring is critical for managing drugs with narrow therapeutic indices like digoxin and phenytoin, ensuring they are both safe and effective. For instance, monitoring theophylline levels in asthma patients involves precision and sensitivity to adjust doses according to individual responses to therapy, ensuring efficacy and...

Tissue-Drug Binding: Localization of Drugs and its Significance

Body tissues, comprising approximately 40% of the body weight, are crucial in drug distribution and localization. These tissues can serve as drug storage sites, competing with plasma binding sites for drug molecules.
Drugs can bind to different tissue components, enhancing their distribution and localization. The factors influencing drug localization in tissues include the drug's lipophilicity, structural characteristics, tissue perfusion rate, and pH differences. These factors determine...

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...
