Background Although the cause of adenotonsillar hypertrophy remains unknown, some studies have shown that allergy may be a risk factor. Purpose This study determined the levels of allergen-specific immunoglobulin E (sIgE) in the adenotonsillar tissues of children with adenotonsillar hypertrophy and evaluated the clinical significance of local atopy in adenotonsillar tissues. Methods We measured 21 types of specific immunoglobulin E in the serum and adenotonsillar tissues of 102 children with adenotonsillar hypertrophy and compared the sensitization patterns of the serum and local tissues. The patients were divided into three groups—atopy, local atopy, and nonatopy—according to the sensitization of serum and adenotonsillar tissues, and the clinical symptoms among the groups were analyzed. Results Seventy-two (70.6%) children with adenotonsillar hypertrophy were sensitized to more than one allergen in the serum and/or adenotonsillar tissue. Thirty (29.4%) children had no IgE positivity to any allergen in both serum and adenotonsillar tissues. Fifty-five (53.9%) were sensitized to at least one allergen in the serum. Seventy (68.6%) were sensitized to at least one allergen in the adenotonsillar tissue. Seventeen (36.2%) of 47 children with specific immunoglobulin E-negative serum had specific immunoglobulin E-positive adenotonsillar tissues. The rate of specific immunoglobulin E was significantly higher in local tissues than in serum. The rate of inhalant allergen specific immunoglobulin E was significantly higher in the adenoids than in the tonsils. However, the rate of food allergen specific immunoglobulin E was significantly higher in the tonsils than adenoids. The lifetime prevalence of asthma and allergic rhinitis, recent symptoms or treatment of allergic rhinitis, and severity of nasal symptoms (rhinorrhea, sneezing, and nasal itching) were significantly higher in children with local atopy than with nonatopy. Conclusions These results confirm that allergic response may be a risk factor for adenotonsillar hypertrophy. Local allergic inflammation may play an important role in childhood adenotonsillar hypertrophy, and local atopy in adenotonsillar tissues can cause respiratory allergic symptoms in children.

Background The results of skin and blood allergen testing are not consistently relevant to clinical manifestations in allergic patients. Objective The aim of the study was to investigate the relationship between severity of allergic rhinitis and different allergen diagnostic tests in Dermatophagoides species-sensitized patients. Methods Study subjects included 65 rhinitis patients—50 with Dermatophagoides pteronyssinus (DP) sensitization (DP+) and 15 without DP sensitization (DP−), and 15 DP+ and 37 DP− healthy controls (HCs) confirmed by allergen skin prick (SPT) and blood specific immunoglobulin E (sIgE) tests. The Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) was tested. All subjects underwent DP nasal provocation test (DP-NPT). Visual analogue scoring (VAS) of nasal symptoms and nasal airway resistance (NAR) were measured before and after NPT. Correlations between the 3 allergen tests and score of RQLQ were performed. Results All rhinitis subjects had significantly higher VAS and NAR after DP-NPT than HCs ( P < .01). All DP+ rhinitis, 40% of DP− rhinitis subjects, 13.3% of DP+ HCs and 0% of DP− HCs had positive DP-NPT. Dose of positive DP-NPT positively correlated with SPT diameter and sIgE level in all tested subjects ( P < .001). Score of RQLQ positively correlated with dose of DP-NPT ( P < .001), but not with SPT diameter and sIgE level in rhinitis patients. Conclusion Although DP nasal provocation, skin prick wheal size and blood sIgE level correlate with each other, only nasal provocation testing is associated with severity of nasal symptoms. It is suggested that NPT should be performed to verify a clinically relevant allergy.

AbstractObjective:To investigate the role of local allergic inflammation and Staphylococcus aureus enterotoxins in chronic rhinosinusitis with nasal polyps.Methods:This study included 36 patients with chronic rhinosinusitis with nasal polyps and 18 controls. Total immunoglobulin E, eosinophil cationic protein, staphylococcal enterotoxin types A and B specific immunoglobulin E, staphylococcal enterotoxin types A and B, and myeloperoxidase levels were determined.Results:Four patients with chronic rhinosinusitis with nasal polyps had a local allergy. All chronic rhinosinusitis with nasal polyps patients tested negative for staphylococcal enterotoxin types A and B specific immunoglobulin E. The chronic rhinosinusitis with nasal polyps group had significantly elevated staphylococcal enterotoxin types A and B levels in the supernatant. Fourteen patients belonged to the eosinophilic chronic rhinosinusitis with nasal polyps group and the others were characterised as having non-eosinophilic chronic rhinosinusitis with nasal polyps.Conclusion:Local allergy may play a role in chronic rhinosinusitis with nasal polyps, independent of staphylococcal enterotoxin superantigens. Staphylococcal enterotoxins may be important in the pathogenesis of chronic rhinosinusitis with nasal polyps; however, their roles as superantigens were not confirmed in this study. In Chinese subjects, chronic rhinosinusitis with nasal polyps usually manifests as a neutrophilic inflammation.

Background and Purpose: Aspergillus fumigatus as a ubiquitous fungus can be found in the respiratory tract of the asthmatic and healthy people. The inhalation of Aspergillus spores leads to an immune response in individuals with asthma and results in the aggravation of the clinical symptoms. The present study aimed to investigate the prevalence of specific immunoglobulin E and G (IgE and IgG) against A.fumigatus in asthmatic patients.Materials and Methods: This study was conducted on 200 consecutive patients with moderate to severe asthma referring to Masih Daneshvari hospital Tehran, Iran, from January 2016 to February 2018. Skin prick test (SPT) was performed in all subjects with Aspergillus allergens. Moreover, all patients underwent specific IgE testing for Aspergillus using Hycor method. Enzyme immune assay was applied to measure total IgE and Aspergillus-specific IgG.Results: According to the results, the mean age of the patients was 45.8 years (age range: 18-78 years). The mean levels of total IgE and Aspergillus specific IgE in asthmatic patients were obtained as 316.3 (range: 6-1300 IU/ml) and 1.5 (range: 0.1-61.3 IU/ml), respectively. Out of 200 patients, 27 (13.5%), 65 (32.5%), 22 (11.0%), and 86 (43.0%) cases had positive Aspergillus SPT, total IgE of > 417 IU/ml, Aspergillus-specific IgE, and IgG, respectively. The level of these variables in patients with severe asthma were 16 (16.5%), 36 (37.1%), 15 (15.5%), and 46 (47.4%), respectively.Conclusion: As the findings indicated, reactivity to Aspergillus is a remarkable phenomenon in asthmatic patients. It is also emphasised that the climatic condition may affect the positive rate of hypersensitivity to Aspergillus.

Abstract Background: House dust mites are the most prevalent allergens in patients with asthma and/or rhinitis in China. Cross-sectional data in 2009 have shown that allergic rhinitis often preceded or occurred at the same time as asthma in patients which was used to investigate the association of serum specific immunoglobulin E (sIgE) levels to house dust mite with the onset of asthma in patients with allergic rhinitis. Methods: 321 patients with allergic rhinitis were face-to-face interviewed and underwent sIgE tests to house dust mite. The temporal sequence of allergic rhinitis and asthma was documented. Univariate analysis, multinomial logistic regression, and Kaplan-Meier survival analysis were performed. Results: Of the 321 participants, 213 (66.4%) had asthma, which occurred after or simultaneously with rhinitis, and 108 (33.6%) suffered from allergic rhinitis only. After controlling basic parameters, factors correlated to sIgE, and essential factors considered by clinical allergists, the risk of developing asthma always increased with the levels of sIgE to house dust mite in all four models (p < 0.01). In Kaplan–Meier analysis, in the first ten years with allergy rhinitis, a high sIgE level represented a high probability of the coexistence of allergic rhinitis and asthma (p < 0.01). For house dust mite sIgE level 5-6, 5 years Rhinitis-Asthma Conversion Rate (RACR) had reached almost 70%. Conclusion: High-level house dust mite sIgE can exist as an indicator of rhinitis to asthma. It provides a theoretical basis for early intervention in patients with high sIgE levels in order to prevent asthma. This assessment and intervention should be performed at the early stage of rhinitis.
