Diagnosis and treatment of paediatric allergy, immunology and infectious diseases — from allergy testing and desensitisation to recurrent infection and immune dysregulation assessment.

ABOUT

About Paediatric Immunology, Allergy & Infectious Diseases

Paediatric Immunology, Allergy and Infectious Diseases is a paediatric sub-specialty focused on diagnosing and treating immunological problems, allergies and infectious diseases in infants, children and adolescents. Care covers immune-system assessment (e.g. primary immunodeficiency, autoimmune disease), identification and management of allergic disease (including reactions to environmental factors, foods and drugs), evaluation of recurrent or unusual infections, prevention and treatment of childhood infections, and guidance on immunisation and infection control.

  • Mumps
  • Hand, foot and mouth disease
  • Pertussis (whooping cough)
  • Recurrent infections: e.g. recurrent pneumonia, meningitis or skin infections
Allergy testing

Allergy testing identifies which allergens trigger reactions. Based on the results, doctors can advise on treatment and management. Depending on symptoms, our centre offers:

Desensitisation therapy

Desensitisation therapy addresses severe allergic reactions to specific allergens. It aims to reduce or eliminate the response and improve tolerance. Methods include:

  • Subcutaneous immunotherapy (SCIT)
  • Sublingual immunotherapy (SLIT)
  • Oral desensitisation
  • Drug desensitisation

Among these, sublingual immunotherapy carries a relatively lower risk and is particularly suitable for children. Patients are still advised to take antihistamines beforehand to reduce side effects. Because allergic reactions may occur during treatment, it must be carried out under medical supervision. Duration varies — from months to years. Desensitisation can be effective in selected cases but is not suitable for all allergic diseases. Doctors decide based on history, the allergen and overall health.
