Depósitos hepáticos positivos para orceína en la cirrosis infantil india
Lancet (London, England)
|June 24, 1978
Resumen
La cirrosis infantil india muestra depósitos únicos de orceína positiva, similares a la enfermedad de Wilson, lo que sugiere un exceso de proteína de unión al cobre. Este hallazgo tiene implicaciones significativas para la comprensión y el tratamiento de las afecciones hepáticas pediátricas.
Área de la Ciencia:
- Hepatología Hepatología.
- Gastroenterología Pediátrica Gastroenterología pediátrica
- La bioquímica es la bioquímica.
Sus antecedentes:
- La cirrosis infantil india (ICC) es una enfermedad hepática pediátrica grave de etiología desconocida.
- Los trastornos del metabolismo del cobre están implicados en diversas afecciones hepáticas, incluida la enfermedad de Wilson.
Objetivo del estudio:
- Para investigar las características histopatológicas de las muestras de biopsia hepática en la cirrosis infantil india.
- Para comparar los hallazgos con los de la enfermedad de Wilson y otras afecciones hepáticas.
Principales métodos:
- Análisis de muestras de biopsia hepática de 12 casos de ICC utilizando la tinción de orcein.
- Comparación con muestras de biopsia de pacientes con enfermedad de Wilson y varios grupos de control (n=279).
Principales resultados:
- Se observó un patrón distinto de depósitos positivos de orceína, indicativos de un exceso de proteína de unión al cobre, en todos los casos de ICC.
- Este patrón se parecía mucho al observado en la enfermedad de Wilson.
- Se encontraron depósitos más leves en aproximadamente el 20% de los casos de control con colestasis prolongada.
Conclusiones:
- Los hallazgos sugieren un papel potencial para el exceso de proteína de unión al cobre en la patogénesis de la cirrosis infantil india.
- La similitud histopatológica observada con la enfermedad de Wilson justifica una mayor investigación sobre el metabolismo del cobre en ICC.
- Estas ideas podrían conducir a nuevas estrategias terapéuticas para las enfermedades hepáticas pediátricas.

01:26Diseases 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...

01:17Hepatic Drug Excretion: Enterohepatic Cycling
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...

01:16Hepatic Drug Excretion: Influencing Factors
The biliary system of the liver, crucial for bile secretion and drug excretion, comprises intrahepatic bile ducts that merge to form the common hepatic duct. This duct, carrying hepatic bile, combines with the cystic duct, draining the gallbladder and forming the common bile duct, which empties into the duodenum. Bile, produced by hepatic cells lining the bile canaliculi, is composed primarily of water, bile salts, pigments, electrolytes, and lesser amounts of cholesterol and fatty acids. Bile...
01:26Pharmacokinetics in Pediatric Patients: Drug Excretion
In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
01:25Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
01:29Hepatic Encephalopathy
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
