Insights

Vaccine coverage is low and delays are common in children with chronic diseases, highlighting a need for improved adherence to recommended and specialized vaccines.

Area of Science:

  • Pediatric Health
  • Immunization Science
  • Public Health

Background:

  • Children with chronic diseases often have unique vaccination needs.
  • Inadequate vaccination can lead to increased risk of preventable diseases in vulnerable populations.

Purpose of the Study:

  • To assess vaccine coverage and identify delays in generally recommended vaccines for children with chronic diseases.
  • To determine factors associated with under-vaccination for vaccines specifically recommended for chronic conditions.

Main Methods:

  • Point-prevalence surveys conducted in pediatric units.
  • Analysis of vaccination data for children aged 2 months to 18 years with chronic conditions.
  • Multivariable analysis to identify factors associated with under-vaccination.

Main Results:

  • Only 47% of children with chronic diseases were up-to-date on general vaccinations.
  • Significant delays (26%-75%) were observed for recommended vaccines.
  • Low maternal education was linked to under-vaccination (aOR=10.5, P=.03).

Conclusions:

  • Children with chronic diseases exhibit insufficient vaccine coverage and substantial vaccination delays.
  • Targeted interventions are needed to improve adherence to vaccination schedules in this population.

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...

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...

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...

Preventive Healthcare Services

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
