title: [Correlation between the magnitude of skin prick test reactivity and pollen-specific serum IgE levels in patients with respiratory allergy].
abstract: BACKGROUND
  For the etiological diagnosis of allergic respiratory diseases skin tests or specific serum IgE determination are used.
  
  
  OBJECTIVE
  To determine the correlation between the extent of reactivity to cutaneous prick tests and the levels of pollen specific serum IgE in patients with respiratory allergy.
  
  
  METHODS
  A prolective, descriptive and transversal study was done with patients of both genders, aged 2 to 60 years, who attended for the first time at the service of Allergy and Clinical Immunology of University Hospital of Puebla, Mexico, with presumptive diagnosis of respiratory allergy. All patients underwent clinical history, skin prick tests with standardized allergenic extracts and quantification of pollen specific serum IgE by chemiluminescence method. We estimated the correlation index r using the statistical method Pearson product-moment correlation coefficient; a value r equal to or higher than 0.70 was considered a significant relationship or a high correlation.
  
  
  RESULTS
  Nine-one patients were included, of whom 58.2% were female. The diagnoses were: allergic rhinitis (79.1%), asthma and allergic rhinitis (16.5%) and only asthma (4.4%). Only significant correlation was found in patients with allergic rhinitis for Rumex crispus (r = 0.702) and in patients with asthma and rhinitis for Ambrosia trifida (r = 1).
  
  
  CONCLUSIONS
  Only for Rumex crispus and Ambrosia trifida, the skin prick tests or the determination of specific serum IgE levels are comparable diagnostic methods of allergic respiratory diseases.
