El agente transmisible en las hepatitis no A, no B
Lancet (London, England)
|March 4, 1978
Resumen
Este estudio demuestra que la hepatitis no A, no B es causada por un agente transmisible. Este agente puede persistir en un estado de portador crónico, como lo demuestra la transmisión exitosa a los chimpancés.
Área de la Ciencia:
- Hepatología Hepatología.
- Virología Virología.
- Medicina de la transfusión Medicina de las transfusiones.
Sus antecedentes:
- Hepatitis después de la transfusión (ETP) es una preocupación significativa.
- Las hepatitis no A, no B representan una parte sustancial de la P.T.H. Los casos. los casos. los casos. los casos.
- El agente causante de la hepatitis no A, no B permaneció sin identificar.
Objetivo del estudio:
- Investigar la transmisibilidad del agente responsable de la hepatitis no A, no B.
- Para determinar si los casos de hepatitis aguda o crónica podrían transmitir la enfermedad.
- Establecer un modelo animal para el estudio de las hepatitis no A, no B.
Principales métodos:
- Inoculación de chimpancés con plasma / suero de pacientes con hepatitis no A, no B y un donante de sangre.
- Monitoreo de chimpancés para pruebas bioquímicas (Alanina Aminotransferasa - ALT) y histológicas de hepatitis.
- Comparación de los períodos de incubación y los niveles de ALT entre chimpancés y pacientes humanos.
- Pruebas serológicas para los virus de la hepatitis A y B.
Principales resultados:
- La hepatitis se desarrolló en 5 de los 5 chimpancés inoculados, confirmado por datos bioquímicos e histológicos.
- El período medio de incubación en los chimpancés fue de 13,4 semanas.
- Los niveles máximos de ALT en los chimpancés variaron, con cambios histológicos correlacionados con la elevación de ALT.
- No se encontró evidencia de hepatitis A o B; la transmisión ocurrió tanto en casos agudos como crónicos, lo que sugiere un estado de portador crónico.
Conclusiones:
- La hepatitis no A, no B es causada por un agente transmisible.
- El agente puede persistir en un estado de portador crónico, permaneciendo potencialmente infeccioso a largo plazo.
- Los chimpancés sirven como un modelo viable para el estudio de este agente de hepatitis transmisible.

Blood Transfusion
Blood transfusion is a critical medical procedure that saves lives and treats various medical conditions. It involves transferring blood from a donor to a recipient. This process requires a thorough understanding of the ABO blood group system and its associated antigens and antibodies.
Blood Transfusion Overview
A blood transfusion is a medical procedure used to replace blood lost due to injury, surgery, or to treat conditions such as anemia or cancer. During a transfusion, donor blood is...

Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
Yellow Fever
Yellow fever is a viral hemorrhagic disease caused by the yellow fever virus (YFV), a member of the Flaviviridae family. It is transmitted primarily by Aedes and Haemagogus mosquitoes in tropical and subtropical regions of Africa and South America. After transmission through a mosquito bite, the virus initially replicates in skin-resident immune cells such as dendritic cells and macrophages. These cells then migrate to the lymph nodes, where viral replication increases, eventually leading to...
Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Hepatitis
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...
Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
