Insights

Paediatric food-induced anaphylaxis (FIA) hospital presentations in New Zealand children increased 2.8-fold over a decade. Rates were higher in males, infants, and Asian/Pacific children, with nuts being the most common allergen.

Area of Science:

  • Pediatric Allergy and Immunology
  • Epidemiology
  • Public Health

Background:

  • Global incidence of paediatric food-induced anaphylaxis (FIA) is rising.
  • Limited epidemiological data exists for FIA in New Zealand (NZ) children.
  • This study addresses the knowledge gap on FIA trends in NZ.

Purpose of the Study:

  • To determine the incidence of paediatric FIA hospital presentations in NZ.
  • To analyze trends and demographic variations in paediatric FIA over a 10-year period.
  • To inform the review of NZ paediatric allergy services.

Main Methods:

  • Analysis of Ministry of Health public hospital discharge data (2006-2015).
  • Identification of acute FIA hospitalizations using ICD codes (T78.0, T78.2) and free text.
  • Calculation of annualised presentation rates per 100,000 children.

Main Results:

  • Overall annualised FIA rate was 16.2 per 100,000 children.
  • Significant increases observed over the 10-year period (2.8-fold rise).
  • Higher rates in males, children under 2 years, and Asian/Pacific ethnicities. Nuts (especially peanuts) and cow's milk were common allergens.

Conclusions:

  • Findings align with international trends of increasing paediatric FIA.
  • Data highlights disparities in FIA rates by gender, age, and ethnicity.
  • Further investigation is needed to understand these differences and ensure equitable care.

Allergic Reactions: Anaphylaxis01:30

Allergic Reactions: Anaphylaxis

Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin,...

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...

Pharmaceutical Poisoning: Potential Scenarios

Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

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...
