This study was conducted to determine the sensitivity to Dermatophagoides pteronyssinus (Trouessart) and D. farinae Hughes with skin prick tests (SPT) and serologic tests in patients with allergic rhinitis (AR), and to specifically search for those mites in homes of patients. A total of 51 participants, (23 patients and 28 controls) were utilized. Skin-prick tests with D. pteronyssinus and D. farinae allergens were performed on all participants, and serum levels of allergen-specific lgE and total IgE were also measured. Dust samples were collected from homes of all participants and examined under a stereo microscope. 977 D. pteronyssinus (mean 44.4/g) and 24 D. farinae (mean 4.0/g) were isolated from the homes of patients, whereas 35 D. pteronyssinus (mean 4.4/g), and four D. farinae (mean 2.0/g) were isolated from the homes of the controls. Patients with D. pteronyssinus in their homes had 95.5% sensitivity to the species according to SPT and 27.3 according to IgE. Patients with D. farinae in their homes had 83.3% sensitivity to the species according to SPT, and 50% according to IgE. Dermatophagoides pteronyssinus sensitivity in the controls was detected as 12.5% according to SPT; however, D. farinae sensitivity was not detected according to both SPT and mite-specific IgE. Differences between patients and controls utilizing SPT results was statistically significant, but not when using mite-specific IgE results. As a result, it was determined that patients with AR in Erzincan province were sensitized to D. pteronyssinus and D. farinae, and that their homes contained those species. It may be helpful to consider these findings in clinical assessment of patients with AR, and also in treatment utilizing immunotherapy techniques.

Background: Allergic rhinitis (AR) is characterized by an IgE-mediated reaction. Aging usually induces a progressive decline of immune system function. There is common belief that both allergic symptoms severity and serum IgE production decline during aging. Objective: This study aimed to evaluate the possible impact of age on: i) serum allergen-specific IgE levels in a large sample of subjects, and ii) AR symptom severity in a group of mono-allergic patients. Methods: Serum allergen-specific IgE to birch, Bet v 1, Parietaria, and Dermatophagoides pteronyssinus were measured by immunofluorometric assay (IFMA) in a sample of 8098 subjects. AR symptom severity was assessed by visual analogue scale (VAS) in a sub-group of 531 mono-allergic patients. Results: The analysis of variance showed that IgE to Bet v 1, birch, and Dermatophagoides pteronyssinus significantly decreased considering the age, whereas IgE to Parietaria did not significantly decline in respect of the age. Considering the global sample of mono-allergic patients, elderly subjects (over 65 years old) tended to have lower IgE levels, but had significantly lower VAS rating, and significantly less sensitizations than adult subjects (18-65 years old). In both adult and elderly patients VAS strongly correlated with IgE values. Conclusions: Allergen-specific IgE levels tend to reduce with aging, but with differences between types of allergy. The IgE decrease is usually associated with reduced AR symptom severity. Elderly AR patients seem to have a different phenotype/endotype in comparison with adult AR ones, characterized by milder symptoms, lower IgE production, and less sensitizations. However, a close positive relationship between IgE values and VAS scores is shared by both adult and elderly AR patients, confirming the close link between allergy and symptoms that persists also in the elderly.

Non Allergic Rhinitis

Nonallergic rhinitis with eosinophilia syndrome (NARES) is a syndrome containing the symptoms similar to allergic rhinitis, with absence of atopy and the presence of eosinophila more than 20% in smears from nasal mucosa. Pathophysiology of NARES has not been studied completely, but permanent eosinophilic inflammation is the keystone of NARES pathogenesis. This disease is marked by local eosinophilic infiltration without atopy, confirmed by negative skin tests, normal levels of total and specific IgE in serum, negative nasal provocation tests with allergens. Nowadays this nosology is considered to be poorly understood.

Abstract Background Allergic rhinitis is the most prevalent allergic disease, and the prevalence and sensitization patterns differ among countries. Identifying the most common inhalant allergen in each region plays a key role in the diagnosis and management of allergic rhinitis. There are no data available about the most prevalent aeroallergen among allergic rhinitis patients in Egypt. The aim of this study is to evaluate the prevalence of positive serum allergen-specific IGE to common inhalant allergens among allergic rhinitis patients in Egypt. A cross-sectional study was conducted on 354 allergic rhinitis patients, serum allergen-specific IGE was measured by using the Immuno CAP system to 16 common regional aeroallergens including (pollens, mite, molds, animal dander, and cockroach). Results The overall rate of sensitization to any allergen was 74.6%. Dermatophagoides pteronyssinus, birch pollens, and Dermatophagoides farina were the most prevalent allergens (29.7%, 23.7%, and 18.6%), respectively. Cladosporuim molds were the least prevalent individual allergens (1.7%). Conclusion Our data suggest that Dermatophagoides pteronyssinus and birch pollens were the predominant allergen sources among allergic rhinitis patient in Egypt.

Allergic rhinitis is a common health problem usually treated with drug therapy. Some patients experience side effects of drug therapy while others fear the use of drugs. Acupuncture is an interesting alternative to traditional treatment. The few studies evaluating acupuncture indicate a possible clinical effect on allergic rhinitis. This study compared active versus sham acupuncture in 40 consecutive patients with a history of allergic rhinitis and a positive skin test. Patients were randomized and assessed prior to treatment and then reassessed after 12 months. Improvements in symptoms using visual analogue scales, reduction in skin test reactions and levels of specific immunoglobin E (IgE) were used to compare the effect of treatment. For one allergen, mugwort, a greater reduction in levels of specific IgE ( p =0.019, 0.039) and skin test reaction ( p =0.004) was seen in the group receiving active acupuncture compared to the group receiving sham acupuncture. However, this finding might be an artifact. No differences in clinical symptoms were seen between active versus sham acupuncture, thus the conclusion being that the effect of acupuncture on allergic rhinitis should be further evaluated in larger randomized studies.

Eosinophils are important to the pathogenesis of allergic asthma, and are increased in bronchoalveolar lavage within four hours after bronchoprovocation of allergic asthmatic patients, and remain significantly increased up to 24 hours later. While the components of human eosinophil granules have been recently isolated and purified, the mechanisms of degranulation have yet to be elucidated.We obtained blood from two volunteers who had a history of allergic rhinitis and asthma and a positive skin test (5x5mm wheal) to Alternaria and Ragweed. Eosinophils were obtained using a modification of the method described by Roberts and Gallin.
