title: [Latex allergy in a paediatric hospital. Characteristics and risk factors].
abstract: BACKGROUND
  The prevalence of latex sensitisation varies according to the population studied. There are various risk factors that increase latex sensitisation, such as genetic risk, atopy, and multiple surgeries.
  
  
  OBJECTIVE
  To characterise patients referred to an Immunology Unit with suspected latex allergy, and to analyse their clinical features and risk factors.
  
  
  METHODS
  A retrospective, descriptive study was conducted on children suspected of latex allergy. Their medical records were reviewed in order to assess symptoms with contact or exposure to latex materials. Known risk factors to latex sensitisation, such as pathologies requiring repeated surgery (spina bifida, myelomeningocele, scoliosis and nephro-urological alterations), atopy (rhinitis, asthma, atopic dermatitis) were investigated. A prick test and/or specific IgE to latex were also performed. A multivariate logistic regression model was performed to find associations between symptoms triggered by exposure to latex with underlying diseases and other risk conditions.
  
  
  RESULTS
  A total of 106 patients were enrolled in the study, of whom 50 were evaluable. At diagnosis 96% of patients were older than five years. Most of the risk factors described were observable in these patients, such as multiple surgeries, neurological and nephro-urological malformations, surgery before one year-old, and repeated bladder catheterisation. After latex exposure, mucous cutaneous manifestations were the most common (52%), followed by respiratory symptoms (36%). All patients were sensitised and allergic to latex.
  
  
  CONCLUSIONS
  Latex allergy is a significant problem in children with risk factors. The results shown in this study raise important challenges for preventive measures and awareness.
