Overview
Active versus Passive Immunity01:31

Active versus Passive Immunity

Immunity, along with the ability to limit pathogen growth to prevent significant body tissue damage, can be gained either by (1) actively developing an immune response within the individual after exposure to a pathogen or after getting vaccinated or (2) passively transferring immune components from an immune individual to one who is nonimmune. Both these forms of immunity can be found naturally and in medical practices.

Development of Immunocompetence01:22

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.
Subsequent T...
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...
Drug Dosing: Infants and Children01:29

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
Pharmacokinetics in Pediatric Patients: Drug Excretion01:26

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

  • Política de salud pública Política de salud pública.
  • Prácticas de inmunización Prácticas de inmunización

Sus antecedentes:

  • La extrainmunización, definida como dosis de vacuna que exceden el esquema recomendado, no se entiende bien.
  • Las implicaciones para la salud pública de la extrainmunización requieren más investigación.

Objetivo del estudio:

  • Cuantificar la prevalencia y el costo financiero de la extrainmunización en niños.
  • Para identificar los factores asociados con la recepción de vacunas adicionales.

Principales métodos:

  • Análisis de los datos de la Encuesta Nacional de Inmunización de los Estados Unidos de 1997.
  • La inclusión de 32.742 niños de entre 19 y 35 meses, con historial de vacunación de proveedores de atención médica para 22.806.
  • Estimaciones ponderadas para representar a la población nacional.

Principales resultados:

  • La vacunación contra el poliovirus tuvo la tasa de extrainmunización más alta (14,1%).
  • En general, el 21% de los niños recibió al menos una dosis adicional de la vacuna, en comparación con el 31% que recibió menos de lo recomendado.
  • Tener múltiples proveedores de inmunización aumentó significativamente la probabilidad de extrainmunización (OR 2.8).
  • Los costos anuales para la extrainmunización se estimaron en 26,5 millones de dólares.

Conclusiones:

  • La vacunación adicional representa una carga financiera significativa.
  • Las estrategias para reducir la extrainmunización no deben comprometer los esfuerzos contra la subinmunización.
  • El mantenimiento mejorado de registros de inmunización y el intercambio de datos son cruciales para minimizar las dosis innecesarias de vacunas.
