Summary
This article offers hepatologists essential information on liver-based inborn errors of metabolism, focusing on treatable conditions and liver transplantation options for adult patients.
Area of Science:
- Hepatology
- Metabolic Disorders
- Genetics
Background:
- Liver-based inborn errors of metabolism (HBIEMs) are a group of genetic disorders affecting liver function.
- These conditions can lead to severe health complications if not managed appropriately.
- Hepatologists play a crucial role in diagnosing and managing these complex diseases in adults.
Purpose of the Study:
- To provide hepatologists with essential information on HBIEMs.
- To highlight HBIEMs that are potentially treatable with liver transplantation.
- To serve as a reference for clinicians encountering these rare diseases.
Main Methods:
- Review of existing literature on liver-based inborn errors of metabolism.
- Focus on conditions amenable to liver transplantation.
- Compilation of relevant references for further study.
Main Results:
- Identification of key HBIEMs relevant to adult hepatology.
- Emphasis on the role of liver transplantation as a therapeutic option.
- Provision of a curated list of references for advanced learning.
Conclusions:
- Hepatologists require specialized knowledge of HBIEMs for effective patient care.
- Liver transplantation is a viable treatment for select HBIEMs.
- This review serves as a valuable resource for clinicians managing these rare metabolic disorders.

01:20Inborn Errors of Metabolism
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
01:24Pharmacokinetics in Pediatric Patients: Drug Metabolism
In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...
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...
01:30Liver Physiology
The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can also...

01:24Overview of Lipid Metabolism
Lipid metabolism is a crucial process in the human body that involves the synthesis and degradation of lipids. This process is essential for energy production, cell membrane formation, and hormone production, among other functions.
Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...
