Consecuencias de la rubéola materna confirmada en etapas sucesivas del embarazo
Lancet (London, England)
|October 9, 1982
Resumen
La infección materna por rubéola durante el embarazo, especialmente en el primer trimestre, aumenta significativamente el riesgo de síndrome de rubéola congénita en los bebés. La rubéola en el embarazo temprano representa la mayor amenaza para los defectos de nacimiento graves.
Área de la Ciencia:
- Obstetricia y Ginecología.
- La pediatría es la medicina de los niños.
- Enfermedades infecciosas Enfermedades infecciosas.
Sus antecedentes:
- El síndrome de rubéola congénita (SRC) sigue siendo una preocupación a pesar de los programas de vacunación contra la rubéola.
- Comprender los riesgos precisos asociados con la rubéola materna en diferentes edades gestacionales es crucial para la atención prenatal y las estrategias de salud pública.
Objetivo del estudio:
- Evaluar prospectivamente la frecuencia de la infección por rubéola congénita y la incidencia de defectos de nacimiento asociados.
- Para determinar la relación entre el momento de la infección materna por rubéola durante el embarazo y los resultados fetales / infantiles.
Principales métodos:
- Prospectivo de seguimiento de más de 1.000 mujeres embarazadas con infección por rubéola confirmada.
- Evaluación clínica y serológica de bebés nacidos de madres infectadas hasta los 2 años de edad.
- Comparación de los resultados entre los infantes infectados y los que no contrajeron la infección.
Principales resultados:
- Las tasas de infecciones congénitas fueron más altas (más del 80%) en las primeras 12 semanas de embarazo, disminuyendo al 54% a las 13-14 semanas y al 25% al final del segundo trimestre.
- Todos los bebés infectados antes de las 11 semanas mostraron defectos de rubéola, principalmente enfermedad cardíaca congénita y sordera.
- Los defectos, principalmente la sordera, ocurrieron en el 35% de los bebés infectados entre las 13 y 16 semanas; no se observaron defectos en los infectados después de las 16 semanas.
Conclusiones:
- La infección materna por rubéola en el embarazo temprano conlleva un riesgo sustancial de defectos congénitos graves.
- La vigilancia continua de la rubéola durante el embarazo es vital para monitorear la efectividad del programa de vacunación e identificar embarazos en riesgo.

01:28Development of the Oral Microbiota
19
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

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...

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

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.

01:07Teratogenicity
4.5K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
