Profilaxis contra el virus sincitial respiratorio en bebés prematuros
Lancet (London, England)
|September 29, 1999
Resumen
Los bebés prematuros ventilados mecánicamente con bronquiolitis por el virus sincitial respiratorio (VSR) enfrentan un mayor riesgo de infección grave. Este riesgo persiste hasta las 44 semanas de edad posconcepcional, especialmente para las personas sin enfermedad pulmonar crónica.
Área de la Ciencia:
- Neonatología Neonatología.
- Enfermedades Infecciosas Pediátricas
- Medicina de las vías respiratorias.
Sus antecedentes:
- Este estudio investigó la edad posconcepcional en la que los bebés prematuros tienen un mayor riesgo de bronquiolitis grave por el virus sincitial respiratorio (VSR).
- La investigación se centró en 33 bebés prematuros con ventilación mecánica diagnosticados con bronquiolitis por VRS.
Objetivo del estudio:
- Determinar la edad postconcepcional a la que los bebés prematuros con bronquiolitis por VRS ya no corren un mayor riesgo de enfermedad grave.
- Evaluar la influencia de la enfermedad pulmonar crónica en la gravedad y duración del riesgo de VSR en esta población.
Principales métodos:
- Se realizó un estudio retrospectivo en 33 bebés prematuros con ventilación mecánica diagnosticados con bronquiolitis por VRS.
- Los datos recopilados incluyeron la edad posconcepcional en el momento de la infección y la presencia de enfermedad pulmonar crónica.
Principales resultados:
- Los bebés prematuros con bronquiolitis por VRS con ventilación mecánica tenían un mayor riesgo de infección grave.
- Este riesgo elevado se extendió hasta una edad posconcepcional de 44 semanas.
- Los bebés prematuros sin enfermedad pulmonar crónica demostraron este riesgo prolongado.
Conclusiones:
- La edad posconcepcional es un factor crítico para determinar el riesgo de bronquiolitis grave por VRS en bebés prematuros.
- Una edad posconcepcional de 44 semanas es un hito significativo para reducir el riesgo en este grupo vulnerable.
- El monitoreo y el manejo cercanos son esenciales para los bebés prematuros con RSV hasta que se alcance esta edad, especialmente aquellos sin enfermedad pulmonar crónica.

01:25Transmission-based Precautions II: Airborne and Protective Environment
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

01:23Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...

01:22Development 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.
Subsequent T...

01:28Development of the Oral Microbiota
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,...
01:28Diphtheria
Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
01:29Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
