Human Liver Microphysiological System for Assessing Drug-Induced Liver Toxicity In Vitro
Published on: January 31, 2022
Summary
Drug-induced liver injury (DILI) is a common adverse drug reaction. While some DILI is directly toxic, many cases are idiosyncratic and may have dose-dependent factors, requiring careful diagnosis and management.
Area of Science:
- Hepatology
- Clinical Pharmacology
- Toxicology
Background:
- Drug-induced liver injury (DILI) is a significant adverse drug reaction.
- DILI presents with diverse clinical and histological features, often mimicking other liver diseases.
- While paracetamol toxicity is directly toxic, other DILI cases exhibit unpredictable, idiosyncratic patterns.
Purpose of the Study:
- To highlight the importance of considering DILI in patients with liver dysfunction.
- To discuss the dose-dependent component of idiosyncratic DILI.
- To outline diagnostic and management strategies for DILI.
Main Methods:
- Review of clinical presentations and histological findings in DILI.
- Analysis of dose-dependency in idiosyncratic drug reactions.
- Discussion of diagnostic challenges and exclusion criteria for DILI.
Main Results:
- DILI can mimic any known liver disease, lacking pathognomonic features.
- Idiosyncratic DILI, initially considered dose-independent, often shows a dose-dependent component.
- Diagnosis of DILI is primarily achieved through exclusion of other causes.
Conclusions:
- Physicians must maintain a high index of suspicion for DILI in patients with liver dysfunction.
- Discontinuation of the offending drug is crucial.
- Hospitalization and consideration for liver transplantation are necessary for severe DILI cases with jaundice or coagulopathy.

01:22Effect 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...
01:26Effect 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...
01:16Drug toxicity: Idiosyncratic Reactions
Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...
01:24Drug Toxicity: Dose-Dependent Reactions
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
01:14Effect 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...
01:00Drug Toxicity: Overview
Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...
