Background The prevalence of food allergy (FA) is increasing; consequently the number of patients on elimination diet (ED) due to a suspected diagnosis is also increasing. Diagnosis of food allergy should be based on a convincing history of allergic reactions or on the result of an oral food challenge test. The oral food challenge test (OFC) is the most reliable clinical procedure for diagnosin...

BACKGROUND There are no published data on peanut sensitization in Egypt and the problem of peanut allergy seems underestimated. We sought to screen for peanut sensitization in a group of atopic Egyptian children in relation to their phenotypic manifestations. METHODS We consecutively enrolled 100 allergic children; 2-10 years old (mean 6.5 yr). The study measurements included clinical evaluat...

Food allergy affects many young children and tree nut allergy is accountable for a large number of severe, life-threatening anaphylactic reactions. Cross-reactivity can occur not only with foods that are in the same biological family but also between certain fruits or vegetables and latex (latex-fruit syndrome). We present the case of a previous healthy 5-year-old girl referred to Pediatric/All...

BACKGROUND Profilin is a panallergen found in pollens and fruits. Sensitization to this protein may explain some sensitization to multiple pollen species. We aimed to evaluate sensitization to profilin in patients suffering from respiratory allergy sensitized to pollens, in the Central region of Portugal. METHODS Patients were evaluated for asthma symptoms, rhinitis, conjunctivitis and food a...

Although diagnostic testing methods for food hypersensitivity have improved over time, both in vivo and in vitro methods are significantly flawed, especially as evidenced by the frequent occurrence of false-positive test results. Because of these limitations, oral food challenge testing remains an essential element in the diagnosis and management of food allergy. In fact, the double-blind, plac...

Food allergy has increased dramatically in prevalence over the past decade in westernized countries, and is now a major public health problem. Unfortunately for patients with food allergy, there is no effective therapy beyond food allergen avoidance, and rapid medical treatment for accidental exposures. Recently, oral immunotherapy (OIT) has been investigated as a treatment for this problem. In...

We analyse two cases of Bovine Serum Albumin (BSA) allergy. The first regards a female laboratory technician with a history of bronchial asthma due to cat allergy, who developed an exacerbation of bronchial symptoms as a consequence of BSA powder inhalation at work. To date, sensitization to BSA as a cause of occupational asthma has rarely been reported in the scientific literature. The second ...
