An acquired circulating anticoagulant with anti-factor V activity appeared in a 29 year old AIDS patient with widespread Kaposi's sarcoma following 21 days of fresh frozen plasma therapy for haemolytic and uraemic syndrome. Residual factor V activity was very low (< 5% of normal). However, the inhibitor was of low titre (0.5 Bethesda Units/ml), while(More)
BACKGROUND Cow's milk allergy (CMA) is a frequent food allergy in young children. The oral food challenge is the gold standard for diagnosis, and there is currently no reliable biological test. Our aim was to evaluate the diagnostic potential of a functional assay quantifying allergen-specific Th2 cells in CMA children. METHODS A total of 29 children aged(More)
BACKGROUND Defining suitable markers to diagnose and monitor allergy and its severity is essential to correctly assign patients for specific immunotherapy. Circulating levels of specific IgE are good markers of sensitization, but not of clinically symptomatic allergy. OBJECTIVE To quantify circulating interleukin (IL)-4- and IL-13-secreting T cells(More)
BACKGROUND Allergen-specific serum immunoglobulin E detection and quantification have become an important step in allergy diagnosis and follow-up. In line with the current trend of laboratory test accreditation to international standards, we set out to design and assess an accreditation procedure for allergen-specific serum IgE. METHODS Method validation(More)
