Risk FactorsRisk Factors

• Genetic Predisposition - Multigenic System

Cytokine gene cluster on chromosome 5, Beta chain of IgE receptor on chromosome II, changes on chromosome 12, changes on chromosome 16

• Environmental Factors - Allergen exposure - Indoor air quality - Outdoor air pollution

• Diet - Neonatal exposure

• Infectious Disease - Role of early childhood infections

Environmental Risk FactorsEnvironmental Risk Factors

• Allergen Exposure - High allergen count indoors, especially in bedroom - associated with great severity of allergic disease - Dust mite, cockroach, cat

• Rx - Early intervention with families and children with increase risk of atopy

• Requires - Identification of allergens - Education and support

• Indoor air quality

- Tobacco

- Limited air exchange

• Outdoor Air Pollution - Fossil fuel combustion - Diesel exhaust particles - Ozone - Sulfur dioxide exposure - Respirable particulate matter

- Drive immune response toward IgE production and allergic inflammation

- Suggest - Monitor air quality - Refrain from exercising along roadways and on days with poor air quality - especially during pollen season

• Diet - Neonatal or fetal exposure - Variable data regarding effects of material diet

- More consensus on the effect of early exposure to certain common food allergens (especially cow’s milk, peanuts, eggs)

- Suggest - Delayed introduction of food allergens to the diet

Risk FactorsRisk Factors• Infections - “Hygiene Hypothesis” - Decreased incidence of bacterial infection in developed countries responsible for increased incidence of atopy

- Viral potentiation of allergic inflammation - Respiratory Syncytial Virus - Influenza virus - Rhinovirus

- Viral infections may induce long-term exacerbations of allergy

• Inhaled Corticosteroids and Bone Metabolism - Increased incidence of posterior cataracts - Suppression of HPA axis and systemic effects at higher doses

- Some evidence regarding inhaled corticosteroid effect on growth in moderate to high doses

- No evidence of osteoporosis in young adults

Immunotherapy (Immune Modulation)


• Something old and something new

- Allergen Immunotherapy New understanding of long-term efficacy

• New therapies in clinical trials - Anti-IgE antibody therapy - T-cell epitope peptide therapy

- Allergen Immunotherapy New understanding of long-term efficacy

• New therapies in clinical trials - Anti-IgE antibody therapy - T-cell epitope peptide therapy

• Allergen Immunotherapy - Decreased allergen-specific T-cell proliferation - Evidence of allergen-specific T-cell anergy - Changes in cytokine synthesis - decreases antigen-specific T-cell production of IL-4, altered IL-4: IFN-gamma ratios - Anergy persists for at least three years after cessation of allergy immunotherapy
