CD23, a differentiation marker of B cells is identified with the low-affinity receptor for IgE--FcepsilonRII. The CD23 molecule is continuously cleaved by autoproteolysis into soluble fragments called sCD23, considered as a multifunctional cytokine. sCD23 is supposed to play an important role in IgE synthesis. IgE is a hallmark of atopy and its overproduction is a characteristic feature of alle...

Background. Interleukin-4 (IL-4), a Th(2) cytokine, can stimulate immunoglobulin E (IgE) transcription. No previous studies evaluated the genetic mechanisms in nonatopic AA patients with elevated serum IgE. Objective. To compare serum IL-4 and total IgE levels between Egyptian nonatopic AA patients and healthy subjects and to investigate a possible relation to HLA-DRB1 alleles. Results. Serum I...

IgE, and atopy. Results: We measured the total serum IgE of 155 children. The number of obese and normal weight children with family history of atopic disease who had high level of total serum IgE were 30 and 25 respectively, whereas these children who had normal level of total serum IgE were 6 and 15 respectively [OR 1⁄4 1.9 (95% CI 0.9-3.9)]. On the other hand, obese and normal weight childre...

Objective. Elevated levels of serum IgE and eosinophilia are the indicators of atopy and intestinal parasitic infections. We evaluated the effect of Enterobius vermicularis infection (enterobiasis) on blood eosinophil count and IgE levels in allergic rhinitis. Methods. A total of 110 patients diagnosed with allergic rhinitis (with symptoms of rhinorrhea, itchy nose and nasal congestion) consist...

AIMS Differential diagnosis of allergic conjunctivitis or dry eye is sometimes very difficult to diagnose by symptoms and clinical examination alone, especially in older patients. It was hypothesised that clinically allergic patients who were serum antigen specific IgE negative were candidates for dry eye. METHODS Sixty patients were studied prospectively who were clinically diagnosed with al...

From an article published by our group by Medeiros et al, we discuss and review the literature on the role of serum specific anti-ascaris IgE in patients with respiratory allergies living in countries where helminthic infestations are common. Medeiros et al conducted a study using 101 patients aged 12 to 21 years with respiratory allergy. Median IgE level was 660 IU/mL. Serum specific anti-asca...

Abstract Purpose of review In the recent years, more cases poultry meat allergy, both IgE- or non-IgE-mediated, are being reported. Patients have varied clinical reactivity at various levels sensitivity to different preparations. The lack validated biomarkers renders accurate diagnosis challenging. this review, we aim provide an overview current status allergy along with a description on allerg...

Background. There is little knowledge of the causes for raised serum total immunoglobulin E (IgE) in children. We investigated the association between perinatal, socioeconomic, demographic, clinical, paraclinical, and early life factors, and total serum IgE. Methods. In a random sample of 7-17 year old children, data on possible risk factors were collected using a questionnaire and total serum ...

IgE, and atopy. Results: We measured the total serum IgE of 155 children. The number of obese and normal weight children with family history of atopic disease who had high level of total serum IgE were 30 and 25 respectively, whereas these children who had normal level of total serum IgE were 6 and 15 respectively [OR 1⁄4 1.9 (95% CI 0.9-3.9)]. On the other hand, obese and normal weight childre...

emerging data suggest that measurement of serum ige to peanut components can be clinically helpful and more accurate than ige to whole peanut to predict peanut allergy. not all studies have used prospective samples, multiple components and oral challenges. currently, there are no data on this topic involving italian children. 32 patients (23 males; median age 9 years) with reported history for ...
