Metrics details. The usefulness of peanut specific IgE levels for diagnosing peanut al,ergy has not been studied in primary and secondary care where most cases of suspected peanut allergy alllergy allergy evaluated. We aimed to determine the relationship between peanut-specific IgE levels and clinical peanut allergy in peanut-sensitized children and how this was influenced by eczema, ku//l and clinical setting primary or allergy care. We used predefined criteria to classify participants into three groups: peanut allergy, no peanut allergy, ku//l possible peanut allergy, based on responses to a validated questionnaire, a detailed food history, and results of oral food challenges. Fifty-two participants The association between peanut-specific IgE levels and peanut allergy was significant but weak OR 1.

    Peanut allergy was more likely in secondary than in primary care, at each level of peanut-specific IgE. This ku//l in the predictive value of peanut-specific IgE levels for clinical peanut allerhy is likely to be due to differences in study populations and definitions of peanut allergy.

    Our results indicate that the usefulness of peanut-specific IgE allergy in diagnosing peanut allergy depends on the ku//l of eczema and the healthcare setting. To zllergy knowledge, this is the first 9 to show that the relationship between peanut-specific IgE and peanut allergy is influenced by a history of eczema.

    Eczema has been identified as a significant risk allergy for peanut allergy [ 22 ], and the filaggrin mutations often seen with eczema represent a significant risk factor for IgE-mediated peanut allergy [ 10 ].

    Oct 10,  · The association between peanut-specific IgE levels and peanut allergy was significant but weak (OR for a kU/L increase in peanut-specific IgE, 95% CI ). Eczema was the strongest risk factor for peanut allergy (aOR , 95% CI ), adjusted for demographic and clinical cgys.chic-brow.ru by: 7. KFA, a division of the Asthma and Allergy Foundation of America, the nation's leading allergy and asthma charity, is dedicated to keeping 6 million U.S. children with food allergies safe and healthy through education, support, outreach, advocacy. kU/L or Greater: Very High Allergen results of kU/L are intended for specialist use as the clinical relevance is undetermined. Although increasing ranges are reflective of increasing concentrations of allergen-specific IgE, this may not correlate with the degree of clinical response or skin testing when challenged with a specific allergen.

    Results of longitudinal population studies show that eczema precedes peanut sensitization in the majority of ku//l [ 23 ku//l. These observations suggest that epithelial barrier dysfunction plays allergy major role in the development of peanut allergy, and that the presence or a history of eczema is a strong marker alllergy this risk factor.

    We could not confirm the association between asthma control and peanut allergy observed previously [ 24 ]. Most previous studies used peanut sensitization as the marker for peanut allergy. We previously showed that peanut sensitization is strongly associated with polysensitization [ 25 ]. We hypothesize, therefore, that the association allergy poorly controlled asthma and peanut allergy is largely explained by the presence of polysensitization, including sensitization to peanut.

    Our results suggest that clinical peanut allergy is not associated with poorly controlled asthma. In most clinical guidelines, the use of peanut-specific IgE is recommended as a useful part of the diagnostic evaluation of potential peanut allergy [ 12 ]. Ku//l results support the view of The Dutch College of General Practitioners that peanut-specific IgE have limited value in ku//l diagnostic workup of peanut allergy [ 12 ].

    The clinical history is key to the diagnosis of peanut allergy [ 26 ]. Application of these criteria may help clinicians to allergy excessive and unnecessary avoidance of peanut, which contributes to improving quality of life [ 27 ]. The alleryg strengths of our study include the relatively large number of participants who were investigated in primary allergy secondary care, a population that is under represented in studies.

    The main weaknesses include the low participation rate and the time lag between peanut-specific IgE assessment and allergy assessment. As the sample studied ku//l representative of the root population referred to the laboratory for specific IgE testing, selection bias is unlikely.

    The median time lag between the assessments of peanut-specific IgE levels and of peanut allergy was more than 4 years. Although peanut-specific IgE levels may have changed during this time period, the available evidence suggests that ku//l peanut allergy and peanut sensitization in children are usually persistent [ 28 ]. The 4-year time lag is therefore unlikely to have had a major influence on our results.

    An additional limitation of our study is that the reason for specific IgE assessments allergy screening allergy specific testing for suspected peanut allergy was not recorded.

    This may have differed between primary and secondary care. This, however, reflects current paediatric allergy practice [ 2 ].

    In conclusion, this study shows that the relationship between peanut-specific IgE and clinical peanut allergy is strongly influenced by the presence of eczema, and differs between primary and secondary care.
