About Paediatric Immunology, Allergy & Infectious Disease

Paediatric Immunology, Allergy & Infectious Disease is a paediatric subspecialty involved in the diagnosis and treatment of infants, children and adolescents’ immune and infectious disorders, as well as allergy. Allergy is an immune system reaction that occurs when a person is exposed to certain substances. These substances, also known as allergens, are usually harmless to most people, but could be fatal if contacted with allergic patient.

Common Symptoms
  • Food allergy
  • Allergic rhinitis (Hay fever)
  • Eczema
  • Urticaria (Hives)
  • Asthma
  • Anaphylaxis

According to a questionnaire survey conducted by the University of Hong Kong (LKS Faculty of Medicine, Department of Paediatrics & Adolescent Medicine) in 2005/2006, about 5% of the children aged 14 or younger had an adverse reaction to food. Children who are allergic to certain food are also known to bear a higher risk of having other sensitive conditions such as eczema and asthma. Peanuts, nuts, fish crustaceans, milk, eggs wheat and soybean are among the most common allergenic food in Hong Kong. Allergic conditions caused by some food, such as milk and eggs, have a higher chance to be eased over time. Yet symptoms caused by some other food, including peanuts, nuts and fish, could persist for an extended period.

Our Specialty
    Allergy Test

    Our centre provides multiple test to identify patients’ source of allergy:

    Treatment for Allergy

    Allergy can be treated via medication:

    • Antihistamine
    • Steroidal and non-steroidal cream
    • Antibiotic
    • Antifungal drug

    New generation of injection and biologics are also available in out centre:

    • Anti-IgE injection
    • Biologics injection

    Allergen Immunotherapy

    Allergen immunotherapy, also known as allergy desensitization therapy, is a medical treatment aiming to desensitize patients’ immune systems’ response by exposing them to a larger dose of allergen extract, thereby reducing the allergic symptoms caused. Here are some treatment examples:

    • Subcutaneous injection immunotherapy
    • Sublingual immunotherapy
    • Oral immunotherapy
    • Immunotherapy drug

    Among all the therapies available, sublingual immunotherapy generally has a lower risk of more serious side effects, hence making it more suitable for children. However, antihistamines pre-treatment is still necessary in order to reduce adverse symptoms. Subcutaneous injection immunotherapy, on the other hand, needs to be carried out under doctors’ direct supervision. For safety reasons, patients should also be kept under observation after injection.

    Infant Allergy Risk Index

    Today, around 40-50% of students around the globe suffer from at least one kind of allergies. In Hong Kong, approximately 1 out of 5 children suffers from eczema or allergic rhinitis. These figures indicate the growing prevalence of allergic conditions. Infants with allergies will experience long term hindrance in their health, mood, academic performance and social abilities. Parents should take early action to prevent any allergic condition of their baby.
