Efecto de la inmunoglobulina en la hepatitis A en las guarderías
JAMA
|January 7, 1983
Resumen
La inmunoglobulina (Ig) redujo efectivamente los brotes de hepatitis A en los centros de cuidado diurno. Esta intervención redujo significativamente el tamaño del brote y la propagación dentro de los centros y la comunidad en general, lo que demuestra su valor en el control de la enfermedad.
Área de la Ciencia:
- Salud Pública La salud pública.
- Epidemiología de las enfermedades infecciosas.
- Inmunología Inmunología.
Sus antecedentes:
- La hepatitis A plantea un riesgo significativo de transmisión en entornos congregados como centros de cuidado diurno.
- Las medidas de control efectivas son cruciales para prevenir brotes generalizados en poblaciones vulnerables.
Objetivo del estudio:
- Evaluar la eficacia de la profilaxis de inmunoglobulina (Ig) en la prevención de la propagación de la hepatitis A dentro de los centros de cuidado diurno.
- Evaluar el impacto de la intervención de Ig en el tamaño del brote y la transmisión comunitaria.
Principales métodos:
- Un estudio prospectivo de 21 meses en el que participaron 91 guarderías.
- Administración de inmunoglobulina a todos los asistentes y empleados del centro tras la detección de un caso índice.
- Comparación de los datos de brotes de los centros tratados con Ig con los centros históricos sin tratamiento.
Principales resultados:
- La intervención con inmunoglobulina redujo el tamaño promedio de los brotes de hepatitis en las guarderías de 7,3 a 6,0 casos.
- Los casos de hepatitis A en niños y empleados cesaron en dos semanas después de la intervención.
- Los casos comunitarios de hepatitis A disminuyeron en un 75%, y los nuevos brotes en un 77%.
Conclusiones:
- La administración de inmunoglobulinas es una estrategia eficaz para controlar los brotes de hepatitis A en las guarderías.
- Esta intervención reduce significativamente la transmisión de enfermedades dentro de los centros y limita la propagación terciaria en la comunidad.
- La profilaxis de Ig ofrece una valiosa herramienta de salud pública para el manejo de enfermedades infecciosas en entornos de cuidado infantil.

Humoral Immune Responses
Overview
Transcytosis of IgG
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Healthcare Associated Infections II: Preventive Measures
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Development of Immunocompetence
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.

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...
