The intracellular forkhead winged transcription factor Foxp3 (forkhead box P3) appears to be specifically expressed by naturally occurring Treg cells, particularly in mice, although in humans there is evidence of upregulation of Foxp3 in all T cells on activation. Foxp3 is required for the development and function of naturally occurring regulatory t cells (treg) and expression is sufficient to convert non-regulatory CD4+CD25T cells into cells with regulatory activity. Conversion of peripheral CD4+CD25 naive T cells to Foxp3+CD4+CD25 foxp3+ Treg cells can be induced by TGF-ß. In a murine asthma model, these TGF-ß-induced Treg prevented house-dust mite-induced allergic pathogenesis or infection pathogenesis in lungs. A single independent report has suggested that IL-4 and IL-13 also induce Foxp3+CD25+ Treg from CD4+CD25precursors. (more…)

This study examined the genetic basis of sensitization to house dust mite allergy allergens. A genome scan was conducted using 603 microsatellite markers in 82 nuclear families (366 individuals) of German, British and Portuguese origin with at least two affected siblings. Sensitization to Dermatophagoides pteronyssinus was assessed by determining specific IgE antibody levels detected by immunochemiluminometric assay and immunosorbent assay and categorized as positive or negative relative to a predetermined cut-off point.

Two factors thought to influence the risk factor asthma are the promoting effect of sensitization to house dust mites and the preventive effect of increased omega-3 fatty acids. Although the avoidance of house dust mites allergen has been used as a preventive strategy in several trials, the effect of omega-3 fatty acid supplementation in the primary prevention of asthma and allergic disease is not known.

The potency of an allergen vaccine is the total allergen activity (that is, the sum of the contribution to allergenic activity from any individual IgE molecule specific for any t-cell epitopes on any molecule in the allergen vaccine). It follows that potency measures always will depend on the serum pool or patient panel selected as well as the methodology used. Methods used for the assessment of allergen vaccine potency may be divided into in vitro or in vivo techniques. (more…)

Atopic dermatitis is a chronic inflammatory condition of the skin which usually starts in infancy. It is sometimes called ‘atopic eczema’ or even simply ‘eczema’. Recently, the term ‘atopic eczema dermatitis syndrome’ or eczema symptoms or infantile eczema has also been proposed to indicate the varied nature of this disease. The diagnosis is based on clinical features of a chronic itchy dermatitis with typical morphology and distribution and a relapsing and remitting course. (more…)

There is much controversy as to the role of allergen exposure for the development of atopic sensitization towards this allergen. While in some studies, a clear, almost linear dose-response relation between allergen exposure and sensitization has been found, others described a bell-shaped association with higher levels of exposures relating to lower rates of atopic sensitization. Part of the discrepancy may relate to the type of allergen, since mostly cat but not house dust mite allergy allergen exposure has been shown, in some studies, to exert protective effects at higher levels of exposure.

Atopic Dermatitis is a chronic relapsing skin disease. Several investigations concerning the long-term prognosis of Atopic Dermatitis in children and teenagers have been performed but there are few data for adults. The aim of this study was to investigate the prognosis and prognostic factors in adult patients with Atopic Dermatitis using a long-term follow-up (25–38 years). A follow-up questionnaire was sent to 922 Atopic Dermatitis patients examined in an out-patient clinic between 1960 and 1973 among 1366 registered patients with Atopic Dermatitis. The patients were aged 20 years or older when they visited the clinic and 45 years or older when they answered the follow-up questionnaire. (more…)

Otitis media with effusion is a chronic inflammatory disease of the middle ear space characterized by the accumulation of fluid. Previous investigations have suggested that the immunopathological mechanism underlying the development of middle ear effusion in allergy patients largely involves the effects of Th2 mediators. The investigators set out to determine whether the middle ear compartment may be a component of the united airways in allergic disease by comparing the inflammatory profiles of the middle ear with those of the upper airway. Middle ear effusions, torus tubaris (Eustachian tube mucosa at the nasopharyngeal orifice) and adenoidal tissue biopsies were obtained from 45 patients undergoing simultaneous tympanostomy tube placement for Otitis media with effusion and adenoidectomy for adenoid hypertrophy.
