Allergic rhinitis, rhinoconjunctivitis, and eczema: prevalence and associated factors in children

Background: Allergic rhinitis is one of the most frequent chronic diseases among children. The objective of the study was to assess the prevalence of and the factors associated with self-reported allergic rhinitis symptoms in schoolchildren from Bogota, Colombia. Methodology/principal: We followed the International Study of Asthma and Allergies in Childhood (ISAAC) methodology. Our sample included 3,256 children aged 6 - 7 and 3,830 adolescents aged 13 - 14 years. Results: The prevalence of self-reported allergic rhinitis symptoms was 30.8% among children and 36.6% among adolescents. Factors associated with self-reported allergic rhinitis among children included current asthma and atopic dermatitis symptoms; use of acetaminophen in the first year of life and in the last 12 months; antibiotic use in the first year of life; high- school and university maternal education; smokers at home; and caesarean delivery. Among adolescents, associated factors included current asthma and atopic dermatitis symptoms; current acetaminophen use once per month; frequent fast-food consumption; cat exposure at home; and smoking. Conclusion: Further exploration of factors associated with allergic rhinitis symptoms is needed.

Introduction: The prevalence of allergic diseases is increasing worldwide, affecting about 30% of the population in low to middle-income countries. Research trends on allergic diseases within rural pediatric populations of Latin American countries is scarce. This study aimed to determine the prevalence of allergic diseases (allergic rhinitis, asthma, and atopic dermatitis) and their associated factors using the International Study of Asthma and Allergies in Childhood-III (ISAAC-III) questionnaire in school-aged children from two rural municipalities in Colombia.Materials and methods: This is a cross-sectional study. The ISAAC-III questionnaire was applied to school-aged children attending elementary schools in the municipalities of Soracá and Palmas del Socorro during 2018. The questionnaires were applied to adolescents aged 13–14 years and the parents of 6–7 years old children. Associations were estimated via bivariate and multivariate analysis. Results: Among 261 school-aged children (58.2% adolescents), the prevalence of allergic dis-eases was: allergic rhinitis 11.49% (95% CI: 8.05–15.78), asthma 8.81% (95% CI: 5.82–12.7), and atopic dermatitis 6.13% (95% CI: 3.69–9.53). Associated factors for allergic rhinitis included: female sex (PR: 2.68, 95% CI: 1.17–5.26), asthma (PR: 4.69, 95% CI: 1.96–8.31), atopic dermatitis (PR: 3.55, 95% CI: 1.09–7.83), and higher maternal education (PR: 4.16, 95% CI: 1.45–8.25).Conclusions: The prevalence of allergic diseases in this rural pediatric population was lower compared with that of the previous reports from urban populations. Associated factors found in this study support previous studies. Research addressing modifiable environmental associ-ations is so far scarce in Latin America; further studies are needed to reduce the burden of these diseases in rural populations.

Background and objectives: Ragweed pollen is a major source of allergen, which has rarely been observed in Romania until now. In this study, we evaluated the symptoms and associated factors in patients with allergic rhinitis to ragweed pollen in two distinct regions of Romania. Materials and Methods: We evaluated the records of patients newly diagnosed with allergic rhinitis induced by ragweed pollen in two allergological centers from North-West (NW) and Central parts of Romania between 2013 and 2015. The patients were clinically evaluated regarding disease length, presence, and severity of the allergic rhinitis symptoms and the association with other allergic manifestations (asthma and conjunctivitis). Results: The sensitization to ragweed was significantly higher in the NW part compared to the Central part (18.27% vs 4.1%, p < 0.001). More patients with monosensitization to ragweed pollen were observed in the NE center (27%) compared to the Central one (20.7%). Patients with monosensitization to ragweed pollen presented more severe forms of rhinitis (70% vs 31.5%, p = 0.02) in the NW part compared to polysensitized patients. The total symptoms score was significantly higher in patients from the Central part compared to the NW part (9.21 ± 2.01 vs 5.76 ±1.96, p < 0.001). Bronchial asthma was associated at a similar frequency to allergic rhinitis in both centers, but it was more frequently observed in monosensitized patients in the NW center. Allergic conjunctivitis was more frequently reported by patients from the Central part (75.86 vs 41.9, p = 0.02), while in the NW region it was noticed more commonly in monosensitized patients (65% vs 33.33, p = 0.02). Conclusions: Allergic rhinitis to ragweed pollen has been more frequently reported in the NW part of Romania. Patients with severe forms of rhinitis were observed in the central part, while in the NW the severe forms of disease were reported by patients with monosensitization. Ragweed pollen is intensely allergogenic and determines association of ocular and asthma symptoms. Co-sensitization increases the risk of asthma association.

Background and aims: Respiratory allergens cause several problems for people with allergic rhinitis and are considered as a global challenge. This disease is an IgE-mediated nasal inflammatory disease that is triggered by the contact of the allergen. Therefore, this study was conducted to investigate respiratory allergens and associated factors in patients with allergic rhinitis who referred to a clinic in Shahrekord located in the southwest of Iran. Methods: In this cross-sectional study, 200 patients including 100 males and 100 females were enrolled using a convenience sampling technique. Diagnoses were made according to clinical symptoms and observation. In addition, the skin prick tests were used to detect the allergens. Finally, data were recorded and then analyzed by Stata. Results: Based on the results, 73.5%, 70.5%, 46%, and 43% of the patients were allergic to the following allergens including Dermatophagoid pteronyssinus, Dermatophagoides parinae, tree, and grass, respectively. Further, the mean height in the group with a positive and negative test for the inhaled allergens equaled 144.92±29.72 and 131.65±30.93, respectively, with a statistically significant difference (P<0.05). However, the mean weight, age, and the time at the onset of the disease were not significantly different between the two groups (P>0.05). Furthermore, the negative or positive reaction to the allergens failed to significantly differ with respect to gender, marital status, occupation, the county of residence, the area of residence, family size, and a family history of the disease (P>0.05). Conclusion: Allergic rhinitis is regarded as a common disorder among teenagers and young adults in this setting. Allergy to one or more respiratory allergens was found to be highly prevalent in patients with allergic rhinitis and the highest rate of allergy was observed to the mites, followed by tree and grass.

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.

Nasal Resonance

A group of sophisticated listeners judged the nasal resonance characteristics of normal children versus children evidencing selected rhinologic disorders under three speaking conditions. Results showed that perceptions of denasality are influenced by both speakers and speaking tasks. That is, children with allergic rhinitis and edemic adenoids were perceived as being denasal when they produced VCV utterances and recited sentences. However, their resonance characteristics were deemed normal for vowel productions. Interestingly, children with severely deviated septums were judged to have normal nasal resonance under all speaking conditions. Clinical implications are discussed.
