title: Diagnosis and treatment of allergic rhinitis in children: results of the PETRA study.
abstract: BACKGROUND
  Good control of allergic rhinitis (AR) in children is desirable because it is associated with diseases such as asthma. The aim of this analysis of the PETRA study was to characterise its diagnosis and treatment in Spanish children.
  
  
  METHODS
  Data were analysed for paediatric patients (age 5-17 years, inclusive) included in the PETRA study, which included consecutive patients with allergic rhinitis attending respiratory specialists throughout Spain. Demographic information, disease characteristics (duration, severity according to the Allergic Rhinitis and its Impact on Asthma [ARIA] classification), diagnostic procedures, treatments and physicians' attitudes to treatment were recorded.
  
  
  RESULTS
  Of the original sample of 1043 patients, 260 children were included (mean age, 11.7 years; 56.2% boys; 61.9% allergic to house dust mites (HDM) and 38.1% allergic to grass pollen). By ARIA classification, 180/260 (69.4%) had persistent AR and 176/280 (63%) had moderate disease. Asthma was reported in 89/161 (55%) with HDM allergy and 44/99 (45%) with grass pollen allergy. Symptomatic treatment was prescribed in 98.5%, although disease control had been no better than poor in 57.3%. Allergen specific immunotherapy was administered to 56.9%, and was used more often for HDM AR. When asked why specific immunotherapy was not prescribed, two-thirds of the investigators preferred a wait-and-see approach, prescribing immunotherapy if symptoms worsened or asthma developed.
  
  
  CONCLUSIONS
  Paediatric patients treated by specialists for allergic rhinitis have moderate or severe disease. Symptomatic treatment was extensively prescribed but often did not achieve good disease control. Many specialists preferred a wait-and-see approach before prescribing immunotherapy.
