El antígeno relacionado con el factor VIII (VIII R: AG) en pacientes hemofílicos y en portadores
Lancet (London, England)
|November 17, 1979
Resumen
Una prueba de antígeno relacionada con el factor VIII antes del pico puede ayudar a identificar a los portadores de hemofilia clásica severa (hemofilia). Este hallazgo ayuda a diagnosticar la hemofilia cuando se descartan otras afecciones.
Área de la Ciencia:
- Hematología Hematología.
- Inmunología Inmunología.
Sus antecedentes:
- La hemofilia clásica (hemofilia) es un trastorno hemorrágico hereditario grave.
- La identificación precisa de los portadores es crucial para el asesoramiento genético y la gestión.
Objetivo del estudio:
- Investigar la utilidad de un fenómeno pre-pico en la inmunoelectroforesis cruzada para la identificación de portadores de hemofilia.
- Para evaluar el valor diagnóstico del pre-pico en el diagnóstico de hemofilia.
Principales métodos:
- Examinó los niveles de antígenos relacionados con el factor VIII utilizando inmunoelectroforesis cruzada.
- Se analizó la presencia de un pre-pico en pacientes con hemofilia clásica severa y portadores obligados.
Principales resultados:
- Se observó un pre-pico en 14 de los 14 pacientes con hemofilia clásica severa.
- Doce de los quince transportistas obligados también exhibieron el pre-pico.
- El pre-pico se observó en otras afecciones, como la enfermedad de von Willebrand.
Conclusiones:
- La presencia de un pre-pico en las pruebas de antígeno relacionadas con el factor VIII es un indicador potencial de hemofilia clásica grave.
- Cuando se excluyen otras condiciones, el pre-pico puede ser una herramienta valiosa para identificar a los portadores de hemofilia.

Blood Transfusion and Agglutination

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

The ABO Blood Group
8.6K
The ABO blood group system is a critical element of transfusion medicine, essential for determining blood compatibility in transfusions and organ transplants. It is based on specific antigens, or agglutinogens, present on the surface of red blood cells (RBCs) and corresponding antibodies, or agglutinins, in the blood plasma.

Understanding an individual's blood group is a critical component of transfusion medicine. It ensures compatibility in blood transfusions, organ transplants, and even during pregnancy. Determining these blood groups involves the ABO and Rh blood typing systems, utilizing specific antigens and corresponding anti-sera to identify an individual's blood type.

Antigens Involved in Adaptive Immunity
1.7K
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
