Prevalence of positive skin prick test results in children with Down syndrome: a case-control study

Given the low prevalence of positive SPT results in children with Down syndrome, it is unlikely that allergic rhinitis will be identified as the cause of many of the chronic rhinitis symptoms that many of these children are referred to an allergy practice to have evaluated. It may be helpful to the parents and to the patients themselves to avoid involving another specialist and appointment because they frequently are involved with many specialists for medical care. A larger study would be helpful in confirming the prevalence of positive SPT results in children with Down syndrome.
