Insights

Vitamin D deficiency is common in Egyptian children with allergic rhinitis (AR). Lower vitamin D levels correlate with increased AR severity and symptoms.

Area of Science:

  • Pediatric Allergy and Immunology
  • Nutritional Biochemistry
  • Epidemiology

Background:

  • Allergic rhinitis (AR) is a prevalent condition in children.
  • Vitamin D plays a crucial role in immune system regulation.
  • The association between vitamin D status and AR severity requires further investigation, particularly in diverse ethnic cohorts.

Purpose of the Study:

  • To determine serum vitamin D levels in Egyptian children diagnosed with allergic rhinitis.
  • To investigate the relationship between vitamin D status and the severity of allergic rhinitis.
  • To explore correlations between vitamin D levels, clinical symptoms, and immunoglobulin E in pediatric AR.

Main Methods:

  • Cross-sectional study involving 120 children with AR and 100 healthy controls.
  • Measurement of serum 25(OH)D and 1,25(OH)2D levels in all participants.
  • Statistical analysis to compare vitamin D levels and assess associations with AR severity, symptom scores, and total IgE.

Main Results:

  • Children with AR exhibited significantly lower serum calcium, 25(OH)D, and 1,25(OH)2D levels compared to healthy controls.
  • Patients with moderate/severe AR had significantly lower mean 25-OHD3 levels than those with mild AR.
  • Negative correlations were observed between 25(OH)D levels and total nasal symptom score (r = -0.62) and total IgE levels (r = -0.27) in the AR group.

Conclusions:

  • Vitamin D deficiency is prevalent in Egyptian children suffering from allergic rhinitis.
  • Lower vitamin D levels are significantly associated with increased allergic rhinitis severity in this pediatric cohort.
  • Findings suggest a potential role for vitamin D supplementation in managing allergic rhinitis in children.

Vitamins

Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

Allergic Drug Reactions

Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Marcia's Theory of Identity Status

James Marcia's identity status model provides a framework for understanding how adolescents navigate identity formation through varying degrees of exploration and commitment. Marcia's model builds on Erik Erikson's theories of psychosocial development, focusing specifically on how adolescents reconcile individual aspirations with societal expectations. His model describes identity formation as a dynamic process where adolescents move between different states depending on their level...

Mineral, Vitamin and Water Absorption

Electrolytes are essential minerals and ions primarily obtained from the diet and absorbed through the gastrointestinal tract. Most electrolytes are absorbed in the small intestine. While the absorption of iron and calcium primarily occurs in the duodenum, calcium is also absorbed in the jejunum and ileum. In these regions, passive diffusion contributes to its absorption alongside active transport mechanisms in the duodenum. These ions can exit the enterocytes through specialized active...

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...
