Abstract

A group of 26 patients with allergic asthma and rhinitis, exclusively sensitized to house dust and mites, underwent immunotherapy with an extract of Dermatophagoides pteronyssinus (Allpyral) for a period of 36 months. Every 6 months we carried out a clinical examination and assessed IgE levels, specific IgE to house dust and mites, histamine release curve to house dust and mites, CD3+ CD4+ CD8+ lymphocyte subpopulations, anti-Dermatophagoides pteronyssinus specific IgG and anti-Dermatophagoides pteronyssinus specific IgG4. The results did not show any significant differences in the IgE levels pre therapy and those monitored every 6 months. However, the anti-Dermatophagoides pteronys-sinus specific IgE generally registered a decrease during hyposensitization when compared with the levels obtained before the therapy. The histamine release curve to house dust and mites registered superior histamine release percentages pre immunotherapy to those obtained after 36 months of treatment. The T subpopulations did not show any statistically significant differences at any of the times they were monitored. The assessment of anti-Dermatophagoides pteronyssinus specific IgG did not yield any significant differences in the levels pre, during ...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.

Asthma
