[Inherited metabolic liver disease causing copper deposition]
1First Department of Liver Disease, Beijing YouAn Hospital, Capital Medical University, Beijing 100069, China.
Summary
This review explores inherited metabolic liver diseases causing copper deposition beyond Wilson's disease. It details their pathogenesis and differential diagnosis for better clinical and pathological identification.
Area of Science:
- Biochemistry
- Hepatology
- Genetics
Background:
- Copper is an essential trace element vital for enzyme function, with the liver central to its metabolism.
- Metabolic dysfunctions in copper absorption, transport, or excretion can lead to organ deposition or deficiency.
- Wilson's disease is characterized by hepatic copper deposition, but other conditions also present with this finding.
Purpose of the Study:
- To review inherited metabolic liver diseases associated with hepatic copper deposition.
- To elucidate the pathogenesis of copper accumulation in these non-Wilsonian diseases.
- To outline clinical and pathological approaches for differential diagnosis.
Main Methods:
- Literature review of inherited metabolic liver diseases causing copper deposition.
- Analysis of pathogenesis related to copper metabolism.
- Synthesis of clinical and pathological diagnostic criteria.
Main Results:
- Identified several inherited metabolic liver diseases, distinct from Wilson's disease, that result in hepatic copper accumulation.
- Detailed the specific molecular and physiological mechanisms driving copper deposition in these conditions.
- Highlighted key clinical and pathological features aiding in differentiating these diseases.
Conclusions:
- Hepatic copper deposition is not exclusive to Wilson's disease and occurs in various inherited metabolic liver diseases.
- Understanding the distinct pathogenesis is crucial for accurate diagnosis.
- A combined clinical and pathological approach is essential for effective differential diagnosis.

01:20Inborn Errors of Metabolism
243
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...

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...

01:17Hepatic Drug Excretion: Enterohepatic Cycling
1.8K
Enterohepatic cycling involves the active secretion of drugs and their metabolites into the bile via transporters in the canalicular membrane of hepatocytes. This secretion is an integral part of the digestive process, releasing these substances into the gastrointestinal (GI) tract.
Post-release drugs and metabolites can be reabsorbed into the body from the intestine. For conjugated metabolites like glucuronides, reabsorption requires enzymatic hydrolysis by intestinal microflora. This...

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

01:22Lysosomal Hydrolases
3.9K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

01:24Chronic Pancreatitis I: Introduction
157
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
