Abstract Background Soy protein is an important component of soybeans and is one the 8 most significant food allergens. Yet, the prevalence of soy allergy in the pediatric population is not well defined. Objectives To evaluate the incidence of IgE mediated soy protein sensitization among children with clinical manifestation of atopic disorders by the use of skin prick test (SPT) for soy protein. Methods Two hundred patients with atopic manifestations attending the Pediatric Allergy and Immunology Clinic at the Pediatric Department of Ain shams University, were recruited between January 2017 till January 2018. They were subjected to SPT to soy protein, measurement of total serum IgE and eosinophilic count in the peripheral blood. Results Of the 200 patients, 108 (54%) were males and 92 (46%) were females with a male to female ratio of 1.17:1. Their ages ranged between 2 years and 15 years (mean±SD; 6.0±33.3 years). Seven patients (3.5%) had positive skin prick test to soy protein. The mean value for the absolute eosinophilic count was 0.4x109/L. The median for the total serum IgE level was 50 IU/L. According to age, the highest percentage of soy protein sensitivity was elicited among patients less than 3 years (57.14%), followed by those between 3 to 6 years (28.5%) and those between 6 and 15 years (14.28%). A positive family history of atopy was recorded in 122 (61%) of all cases. In terms of gender, incidence of soya sensitivity was higher among males than females but with no statistical difference. Although the most common allergic manifestations of all studied patients were respiratory (83%), and atopic dermatitis (22.5%), yet positive SPT to soy proteins was elicited in 43% in allergic rhinitis cases, in 29% of asthma patients, in 14% of patients with combined asthma and allergic rhinitis, and 14.3% of patients having eczema. Conclusion Soy protein sensitization is not uncommon in children especially in those with atopic manifestations. Large scale studies are needed to evaluate the actual incidence of soy protein hypersensitivity in children.

Introduction Bent and Kuhn criteria are the most commonly accepted diagnostic criteria for diagnosis of Allergic Fungal Rhinosinusitis. Other diagnostic criteria for the diagnosis of Allergic Fungal Rhinosinusitis include unilateral nasal disease, Charcot Leyden crystals, bony erosions which form the minor criteria in the diagnosis of Allergic Fungal Rhinosinusitis. Clinical and Laboratory features in Allergic fungal rhinosinusitis are variable. These variations in the diagnostic criteria in the diagnosis of Allergic Fungal Rhinosinusitis have been analysed in the present study. Materials and Methods Prospective study was performed on group of 46 patients of Allergic fungal Rhinosinusitis presenting in the Otorhinolaryngology OPD with symptoms of Allergic fungal rhinosinusitis as diagnosed and persisting for more than 3 months during September 2009 to August 2010. Results Absolute eosinophil count was elevated in 80.43%, total serum IgE elevated in 69.67%, skin prick test was positive in 63.05% of patients. CT scan revealed that most common paranasal sinus involved is ethmoid sinus as seen in 73.91% cases., Sphenoid sinus was least involved as seen in 17.40% cases. More than one paranasal sinus were involved in 65.21% of the cases.,Complete opacification of all sinuses with calcified deposits were seen in 4.76% cases. Mucosal thickening was seen bilaterally in 73.91% of the patients and bony erosion was noted in 6.52% of patients. Histopathology of nasal smears revealed Eosinophilia in 80.43% of patients. Inflammatory Charcot Leyden crystals were found in 15.21% of the patients45.65% showed goblet cell hyperplasia . Other types of inflammatory cells were seen in 56.52%of the study population and 23.91% patients showed positive fungal hyphae. Discussion The significance of absolute eosinophil count, skin prick test, histopathology, CT Scan features and nasal smear cytology have been discussed along with review of literature. Conclusion Although management of Allergic Fungal Rhinosinusitis has advanced tremendously with better understanding of underlying pathogenesis, diagnostic strategies are still far from clear and are still emerging. Lot of research work has to be carried out regarding relevant diagnostic criteria for the disease.

Allergic rhinitis (AR) is one of the most common disease in India. The association between eosinophils and allergic diseases has been known since many years. To correlate Nasal smear eosinophilia (NSE), blood absolute eosinophil count (AEC) and total serum IgE levels with severity of the clinical score in patients with allergic rhinitis. This is one-year prospective study in patients (n=60) presented with allergic rhinitis to our institute. After taking consent, all the study participants were subjected for blood AEC, IgE levels and nasal smears for eosinophils. Among the samples, 81.7% were males. The mean age of patients was 35.2 years. AEC &#62; 440 cells/cu.mm was seen in 46.6%, NSE&#62;10% in 81.6% and total serum IgE was elevated &#62; 100 IU/ml in 95.0%. There was a good correlation of NSE and serum IgE with the severity of disease. There was no correlation of blood AEC with the severity of clinical score. Data was analysed using SPSS software.rn NSE and IgE both correlated well with severity of the disease. Nasal smear cytology is a simple procedure having good correlation with severity of clinical score should be used routinely. Testing for serum IgE levels will increase the accuracy with a better diagnostic utility.

Background: Studies from around the world show that the prevalence and incidence of sensitization to allergens are higher in urban settings. Skin Prick Test (SPT) is being used more frequently now to investigate specific allergen sensitivity along with serum IgE level. Objective: The objective of our study was to evaluate the prevalence of sub-clinical allergy susceptibility and to see association with gender, season, age, urticaria, eczema, dermatitis and total serum IgE. Method and methodology: Eight hundred and ninety-two patients referred by dermatologist to rule out allergic sensitizations underwent SPT within one year. We calculated susceptible group and evaluated its ability to predict diseases like urticaria, eczema and non-specific dermatitis in general population. Result: The antigens that had the highest prevalence throughout the year were Mould II (32.38%) and Dermatophagoides farina (33.78%). The susceptibility to allergen was affected by season and age, however was not affected by gender. The predictability was highly statistically significant for Urticaria, Eczema and Non-specific Dermatitis. Conclusion: We conclude that the allergen susceptibility is high and is significantly correlated to the prevalence of allergic disorders in the sample population of a modern city like Shanghai. The susceptibility to allergen is affected by season and age. Keywords: skin prick test; total serum IgE; sub-clinical allergy susceptibility.

Background: Diagnosis of allergic rhinitis is achieved by a combination of patient history and different screening tools, followed by specific provocation testing. Screening tools usually involve a skin prick test (SPT), specific serum IgE or a combination of both. Objective: The purpose of this study was to evaluate the correlation of SPT, intradermal testing and specific serum IgE testing in certain allergens and to evaluate sensitization rates, symptom patterns and time of symptoms in a cohort of patients with suspected allergic rhinitis. Methods: Data on 4653 patients with suspected allergic rhinitis were included and divided into five groups: spring bloomers (birch, hazel, etc.), summer bloomers (grasses and rye), autumn bloomers (ribwort and mugwort), mites and mold. Correlation of SPT, intradermal testing and specific IgE test results using Cohen’s kappa and logistic regression were carried out to evaluate the probability of symptoms. Results: Comparison of SPT and specific serum IgE led to kappa coefficients between 0.33 and 0.47, corresponding to a minor to moderate concordance. Comparing the symptoms reported by patients with sensitization diagnosed by SPT, a correlation was only found for spring and summer bloomers with an odds ratio of 1.5 and 2.1, respectively. The most prevalent symptom in the study cohort was rhinitis, followed by others such as asthma, sense of smell and atopic dermatitis. Conclusions: SPT seems to be more sensitive than specific IgE for detection of sensitization. Patients’ symptoms as well as the timing of symptoms, especially for perennial allergies, are not always very pronounced.

Abstract OBJECTIVE. This study aimed to analyse the association of absolute eosinophil count (AEC), serum IgE and spirometry with co-morbid bronchial asthma in patients with allergic rhinitis. MATERIAL AND METHODS. This study involved 50 patients with signs and symptoms of allergic rhinitis who underwent a clinical examination and various tests, including spirometry, and were followed up regularly. Patients found to have bronchial asthma or nasal polyposis were treated accordingly. RESULTS. The study found the prevalence of bronchial asthma in patients with allergic rhinitis to be 58% and that the severity of bronchial asthma was reduced significantly, with lesser acute attacks and reduced hospitalizations with the effective treatment of allergic rhinitis (p=0.064). CONCLUSION. This study showed that elevated AEC and serum IgE were significantly associated with co-existing allergic rhinitis and bronchial asthma and increased the chance of co-existence of these two pathologies. Spirometry is a useful tool for observing the response to treatment.

Introduction: Allergic rhinitis is one of the most common respiratory diseases. Patient with allergic rhinitis may have elevated level of serum IgE and eosinophil than normal person. Nasal smear eosinophil count is a simple test as well as noninvasive, can be repeated and inexpensive method for diagnosis of allergic rhinitis. Objective: To assess the eosinophil count in nasal smear as an alternative diagnostic test for children with allergic rhinitis. Methods: This cross-sectional study was conducted at the Department of Laboratory medicine and Paediatrics, BSMMU, Dhaka from September 2019 to August 2020 in 120 children (Age up to 18 years both sex). Diagnosed patients of allergic rhinitis according to ARIA-WHO guideline with history and clinical feature who fulfilled the inclusion criteria were selected as study population. After taking informed written consent blood and nasal secretion of allergic patient were drawn for serum IgE and eosinophil count. Nasal smears for eosinophil were stained using Giemsa stain and observed eosinophil under light microscope. Peripheral blood eosinophil count was estimated by hematology auto-analyzer (SYSMEX-XN 2000) and rechecked manually. The serum total IgE level was performed based on sandwich principle of ELISA. Results: The serum IgE level, nasal smear eosinophil count and blood eosinophil count were found increased with severity of allergic rhinitis, which was statistically significant (p<0.001). Pearson’s correlation coefficient test revealed significant positive correlation between nasal smear eosinophil count with serum IgE (r= +.656, p<0.001) and blood absolute eosinophil count (r= +.415, p<0.001). Conclusion: Nasal smear eosinophil count was significantly raised alone with absolute eosinophil count and serum IgE level with the severity of allergic rhinitis in children.

Objectives: Currently, epidemiological data on allergic rhinitis collected through the skin prick test are scarce. Moreover, the relationship of age and sex to allergic rhinitis is not comprehensively understood. This study aimed to characterize allergic rhinitis and the associated clinical manifestations by age and sex. Methods: We retrospectively investigated data from 2883 patients who visited a single university hospital for rhinitis symptoms between January 2003 and December 2014. Of these 2883 patients, 1964 who underwent a skin prick test with 11 standardized allergen extracts and completed a nasal symptom questionnaire were enrolled. The clinical characteristics of allergen sensitization and nasal symptoms were analyzed by sex and age distribution. Results: The prevalence of allergen sensitization progressively decreased with age after peaking at between 20 and 29 years. The sensitization rate was higher in males than in females ( P = .046). The sensitization rate to house dust mites decreased with age, while sensitization to mugwort and ragweed increased. Six allergens ( Dermatophagoides pteronyssinus, Dermatophagoides farinae, mugwort, trees, ragweed, and cats) were sufficient to identify >96% of patients with allergen sensitization. Nasal obstruction tended to decrease with age and was more prevalent in males ( P = .002) than in females, while rhinorrhea ( P = .007) and itching ( P = .013) were more prevalent in females. Total nasal symptom scores did not differ by sex. Conclusions: The clinical characteristics of allergic rhinitis, including allergen-sensitization patterns and related symptoms, varied by age and sex. Six common allergens could be sufficient to generate a cost-effective tool to identify allergic rhinitis.
