Performance of a component-based allergen-microarray in the diagnosis of cow's milk and hen's egg allergy.

Background: The food challenge test (FCT) is the gold standard for the diagnosis of food allergy. This procedure is time consuming, costly and can induce potentially severe symptoms. An ideal in vitro test should allow to avoid the FCT.

Accuracy of a point-of-care testing device in children with suspected respiratory allergy.

Measuring IgE antibodies is useful in the diagnostic workup of allergy and asthma. This study was designed to assess the value of a new point-of-care test (ImmunoCAP Rapid Wheeze-Rhinitis Child [ICR]; Phadia AB, Uppsala, Sweden) in the diagnosis of atopy in children with allergy-like symptoms such as rhinitis, eczema, and recurrent episodes of wheezing. Patients (n = 175; average age, 7.

Long-term follow-up and outcome of a large cohort of patients with common variable immunodeficiency.

Common Variable Immunodeficiency belongs to the group of rare diseases encompassing antibody deficiency syndromes of highly variable clinical presentation and outcome. The multicenter prospective study on a cohort of 224 patients with Common Variable Immunodeficiency provides an updated view of the spectrum of illnesses which occurred at the clinical onset and over a long period of follow-up (mean time: 11 years) and information on the effects of long-term immunoglobulin treatment. The mean age at the time of diagnosis was 26.
