title: Interferon-gamma and IL-10 may protect from allergic polysensitization in children: preliminary evidence.
abstract: BACKGROUND
  A functional defect of T regulatory cells (Treg) has been proposed as pathogenic mechanism of allergic reaction. Polysensitization is a common feature of allergic patients.
  
  
  OBJECTIVE
  It was to investigate the possible role of Treg-Th1 cytokines, in the development of new sensitizations in childhood.
  
  
  METHODS
  Forty monosensitized (MS) children with allergic rhinitis were evaluated and followed-up for 2 years. New sensitizations were investigated. IL-10 and IFN-gamma were evaluated in in vitro experiments.
  
  
  RESULTS
  Children remaining MS showed significant higher production of both IL-10 and IFN-gamma.
  
  
  CONCLUSIONS
  This preliminary study provided evidence that IL-10 and IFN-gamma production could be defective in allergic children prone to develop polysensitization.
