Aldem Budak M, Geckil E. The effect of home environment modification nursing intervention on symptom control, quality of life, and number of triggers in children with allergic rhinitis: A randomized controlled trial. J Pediatr Nurs 2024; 74:e28-e37. [PMID: 37996355 DOI: 10.1016/j.pedn.2023.10.038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 10/30/2023] [Accepted: 10/30/2023] [Indexed: 11/25/2023]
Abstract
PURPOSE The study was conducted to investigate the effects of a nursing intervention aimed at home environment modification on symptom control, quality of life, and the number of triggers in children with allergic rhinitis. DESIGN AND METHODS This one-to-one, parallel-arm, randomized controlled trial was conducted with a pre-test/post-test design. The study used stratified sampling method. A total of 52 participants were randomly assigned to the intervention group (n = 26) and the control group (n = 26). The intervention group received education on home environment modification and the child was provided with anti-allergic bedding set. The control group continued with routine practices. Statistical significance was set at p < 0.05. RESULTS After the nursing intervention for home environment modification, a significant difference was found between the groups in terms of the number of home environment triggers (p < 0.05). According to the mean scores of the Pediatric Rhinoconjunctivitis Quality of Life Questionnaire, no significant difference was found between the groups (p > 0.05). There was no significant difference between the groups in terms of the mean scores for nasal discharge, nasal congestion, sneezing, nasal itching, and eye itching (p > 0.05) after the nursing intervention for home environment modification. CONCLUSION The findings indicate that the nursing intervention for home environment modification is an effective method in reducing the number of triggers in the home environment. However, no significant impact was observed on symptom control and quality of life. PRACTICAL IMPLICATIONS Awareness can be increased by educating children with allergic rhinitis and their families about triggers in the home environment.

International consensus statement on allergy and rhinology: Allergic rhinitis - 2023. Int Forum Allergy Rhinol 2023; 13:293-859. [PMID: 36878860 DOI: 10.1002/alr.23090] [Citation(s) in RCA: 79] [Impact Index Per Article: 79.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Revised: 11/11/2022] [Accepted: 09/13/2022] [Indexed: 03/08/2023]
Abstract
BACKGROUND In the 5 years that have passed since the publication of the 2018 International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (ICAR-Allergic Rhinitis 2018), the literature has expanded substantially. The ICAR-Allergic Rhinitis 2023 update presents 144 individual topics on allergic rhinitis (AR), expanded by over 40 topics from the 2018 document. Originally presented topics from 2018 have also been reviewed and updated. The executive summary highlights key evidence-based findings and recommendation from the full document. METHODS ICAR-Allergic Rhinitis 2023 employed established evidence-based review with recommendation (EBRR) methodology to individually evaluate each topic. Stepwise iterative peer review and consensus was performed for each topic. The final document was then collated and includes the results of this work. RESULTS ICAR-Allergic Rhinitis 2023 includes 10 major content areas and 144 individual topics related to AR. For a substantial proportion of topics included, an aggregate grade of evidence is presented, which is determined by collating the levels of evidence for each available study identified in the literature. For topics in which a diagnostic or therapeutic intervention is considered, a recommendation summary is presented, which considers the aggregate grade of evidence, benefit, harm, and cost. CONCLUSION The ICAR-Allergic Rhinitis 2023 update provides a comprehensive evaluation of AR and the currently available evidence. It is this evidence that contributes to our current knowledge base and recommendations for patient evaluation and treatment.

[PMID: 36407870 PMCID: PMC9635271 DOI: 10.1515/med-2022-0459] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Revised: 02/10/2022] [Accepted: 02/22/2022] [Indexed: 07/26/2023] Open
Abstract
This meta-analysis aimed to investigate the correlation between early-life antibiotic use and allergic rhinitis. PubMed, Embase, and the Cochrane Central Register of Controlled Trials databases were searched for available studies. Eighteen studies covering 1,768,874 children were included. Early-life antibiotics were associated with an increased incidence of allergic rhinitis (effect size (ES) = 5.00, 95% confidence interval [CI]: 4.88-5.13; I 2 = 95.7%, P heterogeneity <0.001). In Asia, Europe, and the USA, the incidence of allergic rhinitis in the antibiotic group was higher than that in the no medication group (Asia: ES = 3.68, 95% CI: 3.38-4.01; Europe: ES = 3.20, 95% CI: 3.00-3.42; USA: ES = 3.68, 95% CI: 2.74-4.95). Compared with the no medication group, children who received antibiotics in the first 1 week of life (ES = 5.75, 95% CI: 2.18-15.18), first 1 year of life (ES = 3.37, 95% CI: 3.20-3.55; I 2 = 64.2%, P heterogeneity = 0.001), or first 3 years of life (ES = 5.21, 95% CI: 2.42-11.19) had a higher incidence of allergic rhinitis. No individual study influenced the estimates of the meta-analysis. The funnel plot showed moderate symmetry and low publication bias. In conclusion, the use of antibiotics in early life was associated with allergic rhinitis. Still, most included studies analyzed antibiotic exposure as a dichotomous variable, without information on the type and dosage of antibiotics.

J Clin Lab Anal 2022; 36:e24316. [PMID: 35285093 PMCID: PMC8993598 DOI: 10.1002/jcla.24316] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Revised: 02/07/2022] [Accepted: 02/16/2022] [Indexed: 11/07/2022] Open
Abstract
BACKGROUND Studies have shown the promising prospects of rosmarinic acid (RosA) for the prevention and treatment of allergic diseases. OBJECTIVE The aim of this study was to investigate the effects of RosA on inflammatory reaction in rat models of allergic rhinitis (AR) after PM2.5 exposure. METHODS Allergic rhinitis rat models were established by ovalbumin sensitization, and PM2.5 was applied at a concentration of 1000 μg/m3 , 3 h a day for 30 consecutive days. RosA was administered via intraperitoneal injection (20 mg/kg/d) for seven consecutive days. Allergic nasal symptoms were recorded. The expressions of interleukin (IL)-4, IL-13, interferon (INF)-γ, and OVA-sIgE were determined by ELISA. Histopathological changes in nasal mucosa were observed by HE staining. mRNA expressions of T-bet and GATA-3 in nasal mucosa were detected by RT-PCR. NF-κBp65 in cell nuclei and IκBα in cytoplasm were analyzed by Western blot. RESULTS PM2.5 exposure worsened allergic nasal symptoms in AR rats, while RosA ameliorated these symptoms. Histopathologically, AR rats exhibited disorganized nasal mucosal epithelium, cell exfoliation, eosinophilic infiltration of lamina propria, gland swelling, and submucosal vascular congestion, which were aggravated by PM2.5 exposure and alleviated by RosA. RosA decreased the expressions of IL-4, IL-13, and increased the level of IFN-γ in PM2.5-exposed AR rats. After RosA intervention, the expressions of GATA-3 mRNA and NF-κBp65 in PM2.5-exposed AR rats were significantly reduced, while those of T-bet mRNA and IκBα were markedly increased. CONCLUSION Rosmarinic acid may alleviate symptoms of AR rat models exposed to PM2.5 through the modulation of the NF-κB pathway and Th1/Th2 balance.

Abstract
BACKGROUND Antibiotics are among the most commonly used drugs in children. In addition to inducing antibiotic resistance, antibiotic exposure has been associated with long-term adverse health outcomes. METHODS A systematic search using PRISMA Guidelines to identify original studies reporting associations between antibiotic exposure and long-term adverse health outcomes in children. Overall pooled estimates of the odds ratios (ORs) were obtained using fixed or random-effects models. RESULTS We identified 160 observational studies investigating 21 outcomes in 22,103,129 children. Antibiotic exposure was associated with an increased risk of atopic dermatitis (OR 1.40, 95% confidence interval (CI) 1.30-1.52, p<0.01), allergic symptoms (OR 1.93, 95%CI 1.66-2.26, p<0.01), food allergies (OR 1.35, 95%CI 1.20-1.52, p<0.01), allergic rhinoconjunctivitis (OR 1.66, 95%CI 1.51-1.83, p<0.01), wheezing (OR 1.81, 95%CI 1.65-1.97, p<0.01), asthma (OR 1.96, 95%CI 1.76-2.17, p<0.01), increased weight gain or overweight (OR 1.18, 95%CI 1.11-1.26, p<0.01), obesity (OR 1.21, 95%CI 1.05-1.40, p<0.01), juvenile idiopathic arthritis (OR 1.74, 95%CI 1.21-2.52, p<0.01), psoriasis (OR 1.75, 95%CI 1.44-2.11, p<0.01), autism spectrum disorders (OR 1.19, 95%CI 1.04-1.36, p=0.01) and neurodevelopment disorders (OR 1.29, 95%CI 1.09-1.53, p<0.01). Dose-response effects and stronger effects with broad-spectrum antibiotic were often reported. Antibiotic exposure was not associated with an altered risk of allergic sensitisation, infantile colic, abdominal pain, inflammatory bowel disease, celiac disease, type 1 diabetes, fluorosis, and attention deficit hyperactivity disorder. CONCLUSION Although a causal association cannot be determined from these studies, the results support the meticulous application of sound antibiotic stewardship to avoid potential adverse long-term health outcomes.

Abstract
We examined the effect of long-term changes in environmental factors on the prevalence of allergic diseases in elementary school students in Ulsan, Korea. This longitudinal study was conducted among 390 students who were enrolled from three elementary schools in Ulsan in both the first (2009-2010) and second survey (2013-2014). The International Study of Asthma and Allergies in Childhood questionnaire was used to determine the prevalence of allergic diseases and hazardous environmental factors. Generalized estimating equations (GEE) were used to investigate the impact of environmental factors on the change in the prevalence of allergic diseases. The survey revealed that an increased risk of allergic rhinitis was associated with exposure to secondhand smoke, the remodeling of a room, the replacement of wallpaper or flooring, the use of a humidifier, and irritation symptoms of air pollution. Atopic dermatitis was associated with the relocation to or repairs of a new house, and allergic conjunctivitis was associated with low levels of weekly physical activity, the use of insecticides, and irritation symptoms of air pollution. The results indicate that (1) allergic rhinitis and atopic dermatitis are associated with indoor pollution, (2) allergic conjunctivitis is associated with exposure to indoor chemical compounds and low levels of weekly physical activity. This study suggested that the proper evaluation and decrease in the number of environmental risk factors could effectively manage allergic diseases.

Abstract
BACKGROUND Allergic rhinitis (AR) is a global disease that affects a huge proportion of people around the world especially in the Middle East, where multiple allergy-promoting factors can be found. Although AR is not fatal, it severely affects the quality of life. However, it is usually overlooked in developing countries due to resource scarcity. METHODS An online questionnaire on social media was used which included demographics, smoking, socioeconomic-status (SES), war-related questions, and the score for allergic rhinitis (SFAR), a simple self-reporting tool with the cut-off point at 7. Findings. This study included 968 subjects with 721 (74.5%) females. The mean age was 24.69 years with AR prevalence at 47.9%. AR was associated with male gender [P = 0.001 (OR, 1.677; 95% CI 1.249-2.253)], having a job [P = 0.049 (OR, 1.309; 95% CI 1.001-1.713)], the having a chronic medical condition (P < 0.0001) mainly other allergies [P < 0.0001 (OR, 9.199; 95% CI 3.836-22.063)] and asthma [P = 0.006 (OR, 5.060; 95% CI 1.396-18.342)], using medications (P < 0.0001) and living in particular provinces (P = 0.010). However, no significant correlation was found with type of work and war factors except being distressed by war sounds [P = 0.027 (OR, 1.348; 95% CI 1.034-1.757)]. Finally, no associations were found with age, consanguinity, SES, educational level, and cigarette or/and shisha smoking (P > 0.05). Interpretation. Approximately half of the sample displayed AR symptoms, indicating a potentially high burden of AR in the community. A correlation to being distressed from war noises was found with AR which could reflect a psychological aspect. In addition, in war harmful allergens are released which can be an additional AR risk factor which adds to the environment in the Middle East that is associated with AR. However, we need further studies to discover and minimize this huge prevalence of AR.

Abstract
Purpose
The present study aims to determine the relationship between functional constipation and lifestyle patterns, eating habits and nutritional status in young adults.
Design/methodology/approach
This study was conducted in 825 young adults between the age of 20 and 24 years in Ankara. Constipation was evaluated via self-reports and ROMA III criteria. Food and beverage consumption frequency and fluid intake were surveyed, and anthropometric measurements (weight and height) were evaluated. Physical activity was assessed using the brief physical activity assessment tool.
Findings
Participants reported themselves as constipated, not constipated and sometimes constipated in 7.8, 39.6 and 53.6 per cent of cases, respectively. These rates differed from those obtained using the ROMA III criteria: constipated 51.3 per cent and not constipated 48.7 per cent. Constipation rates were higher in females (54.4 per cent) than males (44.8 per cent) (p < 0.05). No association was found between daily water, total fluid and fiber intake and constipation (p > 0.05). However, water from foods have lowering effects on constipation (p < 0.05). Increased physical activity seems to have no effect on constipation. According to food frequency records, participants who consumed more whole grains, rice/pasta and vegetables had lower rates of constipation. Conversely, higher consumption of tea was associated with higher constipation rates (p < 0.05).
Originality/value
Young adults should be encouraged to consume foods rich in water such as fruits and vegetables against constipation, fiber-rich foods and fluids to meet the recommendations for healthy eating. Only a few studies have assessed the relationships between lifestyle, fluid and nutritional status and body mass index.

Abstract
This review article aims to present the epidemiology and associated risk factors of allergic rhinitis (AR) in Asia. AR-related literature published on Asia was systematically reviewed and the associated risk factors were investigated. The prevalence of AR in Asia varied considerably depending on the geographical location, study design and population involved. Several risk factors were observed to have strong association with disease presentation across multiple studies. Among these, family income, family size, daily personal computer usage time, personal and parental education attainment, and stress level have shown some level of biological gradient influence when multiple risk levels were analyzed. This suggests that AR manifestation and presentation possibly might be strongly affected by various personal and family factors. These findings are beneficial as they may provide insights into modifiable factors that may influence AR presentation. In addition, these results indicate that strategies to reduce personal and family-related risk factors have to be developed in order to alleviate the odds of AR expression.

Abstract
This study systematically reviewed and quantified the relationship between exposure to antibiotics during the first 2 years of life and the risk of allergies/atopies including hay fever, eczema, food allergy, positive skin prick testing (SPT), or elevated allergen-specific serum/plasma immunoglobulin (Ig) E levels later in life. PubMed and Web of Science databases were searched for observational studies published from January 1966 through November 11, 2015. Overall pooled estimates of the odds ratios (ORs) were obtained using fixed or random-effects models. Early-life exposure to antibiotics appears to be related to an increased risk of allergic symptoms of hay fever, eczema, and food allergy later in life. The summary OR for the risk of hay fever (22 studies) was 1.23, 95% confidence interval (CI):1.13-1.34; I2 : 77.0%. The summary OR for the risk of eczema (22 studies) was 1.26, 95% CI: 1.15-1.37; I2 : 74.2%, and the summary OR for food allergy (3 studies) was 1.42, 95% CI: 1.08-1.87; I2 : 80.8%. However, no association was found for antibiotics exposure early in life and objective atopy measurements including positive SPT or elevated allergen-specific serum/plasma IgE levels.

Abstract
BACKGROUND Critical examination of the quality and validity of available allergic rhinitis (AR) literature is necessary to improve understanding and to appropriately translate this knowledge to clinical care of the AR patient. To evaluate the existing AR literature, international multidisciplinary experts with an interest in AR have produced the International Consensus statement on Allergy and Rhinology: Allergic Rhinitis (ICAR:AR). METHODS Using previously described methodology, specific topics were developed relating to AR. Each topic was assigned a literature review, evidence-based review (EBR), or evidence-based review with recommendations (EBRR) format as dictated by available evidence and purpose within the ICAR:AR document. Following iterative reviews of each topic, the ICAR:AR document was synthesized and reviewed by all authors for consensus. RESULTS The ICAR:AR document addresses over 100 individual topics related to AR, including diagnosis, pathophysiology, epidemiology, disease burden, risk factors for the development of AR, allergy testing modalities, treatment, and other conditions/comorbidities associated with AR. CONCLUSION This critical review of the AR literature has identified several strengths; providers can be confident that treatment decisions are supported by rigorous studies. However, there are also substantial gaps in the AR literature. These knowledge gaps should be viewed as opportunities for improvement, as often the things that we teach and the medicine that we practice are not based on the best quality evidence. This document aims to highlight the strengths and weaknesses of the AR literature to identify areas for future AR research and improved understanding.

Abstract
BACKGROUND Few data are available concerning the time trends and risk factors associated with allergic rhinitis (AR) in schoolchildren in Hungary. METHODS At an interval of six years, parents of 6-12-year-old children completed identical ISAAC-based and additional questionnaires related to possible risk factors. RESULTS Response rate was 62.8% with 6335 questionnaires distributed in 2007, and 52.9% with 6441 questionnaires in 2013. The prevalence of current AR symptoms (subjects presenting clinical symptoms of AR in the past 12 months, but had yet to be diagnosed by physician) increased significantly from 14.9% to 23.5% (p<0.001). There was no significant change in the prevalence of physician-diagnosed AR (11.6-11.2%). In multivariate analysis, gender (OR 0.733; CI 0.642-0.931), a family history of atopy (OR 2.017; CI 1.669-2.436), frequent upper respiratory tract infections (OR 2.033; CI 1.659-2.492), long-lasting disease before the appearance of the allergy (OR 2.119; CI 1.311-3.428), feather bedding (OR 0.773; CI 0.599-0.996) and living in a green area (OR 1.367; CI 1.133-1.650) were found to be significant risk factors of cumulative AR in 2013. In both of the groups with (p<0.000) or without (p<0.003) AR the families with a history of atopy used feather bedding less frequently than families without atopy. CONCLUSION Although the prevalence of physician-diagnosed AR has not shown significant changes during the studied interval, the significant increase of the current AR symptoms suggests growing prevalence of AR among children in Budapest. Our results revealed new aspects of bedding customs in atopic families.

Abstract
Exposure to tobacco smoke has been associated with harmful effects on child health. The association between tobacco smoke exposure and childhood rhinitis has not been established in developed or developing countries. We investigated the association between serum cotinine levels and rhinitis in a population sample of 1,315 Asian children. Serum cotinine levels were positively associated with rhinitis ever (adjusted odds ratio [AOR] = 2.95; 95% confidence interval [CI]: 1.15–7.60) and current rhinitis (AOR = 2.71; 95% CI: 1.07–6.89), while the association for physician-diagnosed rhinitis approaching borderline significance (AOR = 2.26; 95% CI: 0.88–5.83). Stratified analyses demonstrated significant association of serum cotinine levels with current rhinitis among children without allergic sensitization (AOR = 6.76; 95% CI: 1.21–37.74), but not among those with allergic sensitization. Serum cotinine levels were positively associated with rhinitis ever (AOR = 3.34; 95% CI: 1.05–10.61) and current rhinitis (AOR = 4.23; 95% CI: 1.28–13.97) among adolescents but not in children aged less than 10 years. This population-based study demonstrates supportive evidence for positive association of tobacco smoke exposure with rhinitis, while the effect is mainly confined to non-allergic rhinitis and more pronounced in adolescents than in young children, highlighting the need for raising public health awareness about the detrimental effects of tobacco smoke exposure on children’s respiratory health.

Abstract
Objective We aimed to determine the prevalence of allergic rhinitis in children aged 12-15 years who lived in the Trabzon Province, specify possible risk factors, and compare the data obtained with those of the other studies conducted in our country and in other countries. Methods First, 1372 students from nine primary schools determined according to the recommendations of Department of Public Health and approval of The Provincial Directorate of Health were screened in their schools with questionnaire forms. Second, students providing the response "yes" to the first and/or second questions in the questionnaire forms were considered as possible allergic rhinitis patients and invited to our clinic. Then, 246 students were subjected to a skin prick test. Data were collected with the evalution of questionnaire and skin prick test results together. Results The prevalance of allergic rhinitis in children between 12 and 15 years age was found to be 14.5% in Trabzon. Female gender was found to be a relative a risk factor for allergic rhinitis (p=0.015). The prevalence of allergic rhinitis in children whose both parents were smoking was significantly higher than that in children whose only one parent was smoking or both parents were nonsmokers (p=0.0024). In addition, living in an apartment flat (p=0.015) and owing pets (p=0.04) were detected to be other risk factors for allergic rhinitis. Conclusion According to our investigations, this is the first prevalence study in Trabzon, which is the largest settlement in the Eastern Black Sea Region. The prevalence of allergic rhinitis in children was found to be 14.5%. Female gender, smoking habits of the parents, owing pets, and living in an apartment flat are risk factors for allergic rhinitis.

Abstract
OBJECTIVE In epidemiological studies that aim to investigate the relationship between pet exposure and allergy/asthma, pet exposure is often ascertained by means of a questionnaire, but it is unclear which questionnaire items are used. The objective of this study was to systematically review self-reported pet exposure assessment in questionnaires used in epidemiological studies which explore the associations between pets and allergy/asthma. METHODS A systematic literature search was conducted in PubMed and papers were selected according to pre-specified eligibility criteria. The pet exposure questions used were classified within a framework including direct pet contact, indirect pet contact (e.g. through carers or grandparents) and avoidance behaviour. Authors were contacted when the questions used were not reported in detail. RESULTS Ninety-six full text papers were systematically reviewed. All studies assessed direct pet contact, but less than half (45%) explicitly assessed whether pets were allowed indoors. The vast majority of studies assessed both pet exposures during the first year of life and after the first year of life. The minority (13%) assessed whether pet(s) were kept at places regularly visited by the child and pet exposure in utero (15%). Even fewer studies assessed indirect contact to pets (n = 8) and avoidance behaviour (n = 10). CONCLUSIONS In epidemiological studies, the ascertainment of pet exposure through questionnaires appears to vary greatly. This variation might partly explain the inconsistent and contradictory results of the effects of pet exposure on the development of allergy and asthma.

Abstract
Objective The objective of this study was to investigate the relationship between prenatal and postnatal risk factors and the prevalence of allergic rhinitis (AR) in Chinese children of specific ages. Study Design This study was a cross-sectional survey. Students from 8 metropolitan cities in China were studied in November and December, 2005. There were 20,803 elementary-school Chinese children (49.6% boys, mean age, 9.19 years) enrolled. Questions from the standard questionnaire of the International Study of Asthma and Allergies in Children were completed to enable us to examine the pattern of current AR. The potential confounders and pre-and postnatal risk factors were analyzed using logistic regression. Results The overall prevalence of AR was found in this study to be 9.8%. After adjusting for several likely confounders, there was a higher likelihood of AR in school-aged children who were not exclusively breastfed in the first 4 months of their lives (odds ratio [OR]: 1.28; 95% confidence interval [CI]: 1.16–1.41), children who were born post-term (OR: 1.34; 95% CI: 1.12–1.60), children delivered by cesarean section (OR: 1.07; 95% CI: 1.00–1.19), or children born to mothers who experienced depressive symptoms during the pre- and postnatal periods (OR: 1.28; 95% CI: 1.15–1.42). Conclusions AR in school-aged children was found to be associated with pre- and postnatal events. These findings indicate that strategies to reduce exposure to risk factors during pre- and postnatal periods for childhood allergies might be warranted.

Abstract
BACKGROUND The prevalence of allergic rhinitis and other allergies has risen worldwide. Dietary habits are considered to be among the potential risk factors. The aim of this study was to evaluate the prevalence of allergic rhinitis and its relationship with dietary habits and other risk factors among 6 to 7-year-old Turkish schoolchildren. METHODS In this cross-sectional study, a total of 11483 children aged 6-7 years were surveyed. The prevalence of symptoms of allergic rhinitis was assessed using the ISAAC protocol. Dietary information was collected using a food frequency questionnaire. RESULTS Of them, 9875 (50.7% M 49.3% F) questionnaires were appropriately completed. The prevalence rates of lifetime rhinitis, current rhinitis, current rhinoconjunctivitis and physician-diagnosed allergic rhinitis, were 44.3%, 29.2%, 8.5% and 8.1%, respectively. Consumption of rice, and cereals ≥3 times per week showed protective effect on physician-diagnosed allergic rhinitis (aOR = 0.53, 95% CI = 0.32-0.87 and aOR = 0.58, 95% CI = 0.36-0.92). Eating pasta, and chocolates ≥3 times per week showed protective effect on current rhinoconjunctivitis (aOR = 0.45, 95% CI = 0.25-0.79 and aOR = 0.50, 95% CI = 0.29-0.86). Eating lollipops, candies and animal fats ≥3 times per week was positively associated with current rhinoconjunctivitis (aOR = 1.47, 95% CI = 1.00-2.17 and aOR = 2.25, 95% CI = 1.11-4.56). Protective effect of the Mediterranean diet was not significant. CONCLUSIONS Frequent consumption of cereals, rice, pasta and chocolates may have beneficial effect on symptoms of rhinoconjunctivitis. Although dietary habits may affect the prevalence of symptoms of current rhinoconjunctivitis, the Mediterranean diet alone may not be protective against rhinoconjunctivitis.

Abstract
BACKGROUND Parental smoking is one of the controversial risk factors associated with allergic rhinitis. The aim of this study was to investigate the relationship between parental smoking and allergic rhinitis; considering confounding factors. METHODS A cross-sectional study was conducted on 671 children aged 2 to 7 years. Random cluster sampling was used to select the participants. The signs and symptoms of allergic rhinitis in children were assessed through standard questionnaires and physical examinations. RESULTS In the multivariate analysis, parental smoking (odds ratio [OR] 1.07; 95% confidence interval [CI], 0.48-2.41) was not a significant risk factor for allergic rhinitis; positive family history of allergy was the only significant factor among other factors (OR 23.64; 95% CI, 11.63-48.04). Sex (OR 1.16; 95% CI, 0.60-2.24), family size (OR 1.06; 95% CI, 0.22-5.05), family income (OR 0.60; 95% CI, 0.24-1.47), and parents' education (OR 1.79; 95% CI, 0.61-5.20) were not statistically significant. CONCLUSION The findings suggest that there is no significant relationship between parental smoking and allergic rhinitis.

J Allergy Clin Immunol 2013; 132:1099-1110.e18. [PMID: 24028857 DOI: 10.1016/j.jaci.2013.07.028] [Citation(s) in RCA: 98] [Impact Index Per Article: 8.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2013] [Revised: 07/01/2013] [Accepted: 07/16/2013] [Indexed: 01/21/2023]
Abstract
BACKGROUND A substantial proportion of the world's population is exposed to indoor dampness-related exposures. Since the 1990s, studies have assessed the relation between indoor dampness and mold and rhinitis, but the evidence has been inconclusive. No previous meta-analysis has been reported on this topic. OBJECTIVE We conducted a systematic review and meta-analysis of studies on the relations between indoor dampness and mold and the risk of different types of rhinitis and investigated whether these relations differ according to the type of exposure. METHODS A systematic search of the Ovid MEDLINE and EMBASE databases was conducted (1950 through August 2012), and reference lists of relevant articles were reviewed. Cross-sectional, case-control, and cohort studies in children or adults were selected according to a priori criteria and evaluated by 3 authors independently. RESULTS Thirty-one studies on rhinitis, allergic rhinitis (AR), or rhinoconjunctivitis were included. In meta-analyses the largest risk was observed in relation to mold odor (rhinitis: 2.18 [95% CI, 1.76-2.71]; AR: 1.87 [95% CI, 0.95-3.68]). The risk related to visible mold was also consistently increased (rhinitis: 1.82 [95% CI, 1.56-2.12]; AR: 1.51 [95% CI, 1.39-1.64]; rhinoconjunctivitis: 1.66 [95% CI, 1.27-2.18]). In addition, exposure to dampness was related to increased risk of all types of rhinitis. CONCLUSION This meta-analysis provides new evidence that dampness and molds at home are determinants of rhinitis and its subcategories. The associations were strongest with mold odor, suggesting the importance of microbial causal agents. Our results provide evidence that justifies prevention and remediation of indoor dampness and mold problems, and such actions are likely to reduce rhinitis.

Abstract
BACKGROUND Allergic rhinitis (AR) is a global health problem affecting many people from childhood to adulthood. The aim of this study was to evaluate the prevalence of AR and related symptoms, and to assess the risk factors, dietary habits and the Mediterranean diet affecting AR. METHODS In a cross-sectional study design, 9991 children, aged 13-14 years in 61 primary schools in 32 districts of Istanbul were evaluated. The prevalence of AR symptoms among the children was evaluated using the ISAAC protocol. RESULTS In our study, total of 10,984 questionnaires were distributed to 13-14yr-old schoolchildren to 61 schools in 32 district of Istanbul and 9991 questionnaires were suitable for analysis with an overall response of 91.7%. The rates of lifetime rhinitis, rhinitis in last 12 months and lifetime doctor diagnosed AR prevalence were 53.5%, 38.3% and 4.5%, respectively. The variation among districts in the prevalence of doctor diagnosed AR was very high. The highest prevalence was about 10 times higher than in the district with the lowest prevalence (range: 1.4-14.5) of Istanbul. A family history of atopy, mother with a university degree, presence of cat at home during last 12 months and adenoidectomy were significant for increased doctor diagnosed AR risk. Additionally, although fish and other sea foods, fermented drinks made from millets and various seeds, animal fats and butter were independent risk factors for doctor diagnosed AR, fish oil and hamburger were protective foods for doctor diagnosed AR. The MD was not associated with the prevalence of doctor diagnosed AR. CONCLUSIONS This study shows that that there are wide variations for the prevalence of AR related symptoms in 13-14yr-old schoolchildren among districts of Istanbul in Turkey. Socio-economical, environmental factors, some dietary habits, but not Mediterranean diet may affect the prevalence of AR.

Abstract
Health effects of ambient air pollution were studied in three groups of schoolchildren living in areas (suburban, urban and urban-traffic) with different air pollution levels in Eskişehir, Turkey. This study involved 1,880 students aged between 9 and 13 years from 16 public primary schools. This two-season study was conducted from January 2008 through March 2009. Symptoms of asthma, rhinitis and eczema were determined by the International Study of Asthma and Allergies in Childhood questionnaire in 2008. Two lung function tests were performed by each child for summer and winter seasons with simultaneous ambient air measurements of ozone (O3), nitrogen dioxide (NO2) and sulfur dioxide (SO2) by passive sampling. Effects of air pollution on impaired lung function and symptoms in schoolchildren were estimated by multivariate logistic regression analyses. Girls with impaired lung function (only for the summer season evaluation) were more observed in suburban and urban areas when compared to urban-traffic area ([odds ratio (OR) = 1.49; 95 % confidence interval (CI) 1.04-2.14] and [OR = 1.69 (95 % CI 1.06-2.71)] for suburban vs. urban-traffic and urban vs. urban-traffic, respectively). Significant association between ambient ozone concentrations and impaired lung function (for an increase of 10 μg m(-3)) was found only for girls for the summer season evaluation [OR = 1.11 (95 % CI 1.03-1.19)]. No association was found for boys and for the winter season evaluation. No association was found between any of the measured air pollutants and symptoms of current wheeze, current rhinoconjunctivitis and current itchy rash. The results of this study showed that increasing ozone concentrations may cause a sub-acute impairment in lung function of school aged children.

Abstract
UNLABELLED Aerobic plate counts (APC), coliforms, Bacillus cereus, Escherichia coli and eight foodborne pathogens were tested in 1008 cheap and junk foods, including candies, dried cakes, chewing gum, chocolate, dried and seasoned seafood, ice cream, and sugary foods. APCs were positive for 342 samples (33·9%), and the majority of the counts were 2-3 log CFU g(-1) or ml(-1) (average: 1·10 log CFU g(-1) or ml(-1) ). Most samples (97·3%) contained no coliforms (average: 0·07 log CFU g(-1) or ml(-1) ). Bacillus cereus was detected in 68 samples (average: 0·14 log CFU g(-1) or ml(-1) ). Escherichia coli and Listeria monocytogenes were detected in 6 and 1 samples, respectively, whereas other foodborne pathogens were not isolated. The highest bacterial counts were associated with dried and seasoned seafood products and dried cakes, suggesting that appropriate regulations of these food types should be considered. Cheap and junk foods were produced mainly in developing countries, but there were no significant differences in the bacterial counts among different countries of origin. The presence of foodborne pathogens may pose a risk for children. These results suggest that there is cause for deeper concern about the safety of these foods and that effective countermeasures should be established to improve their microbiological safety. SIGNIFICANCE AND IMPACT OF THE STUDY Food safety is especially important for children, but only limited information is available about the microbiological quality of cheap and junk foods that are consumed frequently by primary schoolchildren (e.g. dried cakes, candies and chocolates). The present study investigated the microbial quality of cheap and junk foods, and our results indicate that these foods are a potential health risk for children, therefore, deeper concern about the safety of these foods and effective countermeasures should be established to improve their microbiological safety. The present study may contribute to the development of an appropriate child food safety management system.

Abstract
BACKGROUND Atopic diseases became an important health problem in affluent Western societies. METHODS To study the prevalence and factors associated with the risk of atopic diseases in Germany, data from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) were analysed (n = 17,450). Standardized, computer-assisted personal interviews with parents and parent-administered questionnaires provided physician diagnoses of allergic rhinoconjunctivitis, atopic dermatitis and asthma as well as data on demographic characteristics, migration background, birth order, age at the beginning of nursery, atopic diseases of parents, parents' smoking status, parents' occupation, breastfeeding and living environment. RESULTS The life-time prevalence of atopic dermatitis was 13.2% (95% confidence limit: 12.5-13.9%), 10.7% (10.1-11.3%) for allergic rhinoconjunctivitis and 4.7% (4.3-5.1%) for asthma. At least one atopic disease in parents was the strongest factor associated with atopic diseases in the offspring, with a prevalence ratio of up to 2.6. High and middle socio-economic status (prevalence ratio, 95% confidence limit: 1.28, 1.12-1.46; 1.15, 1.01-1.32) were associated with the risk of atopic dermatitis, whereas a two-sided background of migration reduced the risk (0.76, 0.65-0.88). Factors that reduced the risk of allergic rhinoconjunctivitis were parents working as self-employed farmers (0.48, 0.30-0.76) and older siblings (0.80, 0.71-0.89), whereas the beginning of nursery school at older age was associated with an increased risk in children who were cared for outside the family before school age (1.05, 1.00-1.10). Living in mould-infested rooms (1.64, 1.23-2.19), an urban living environment (1.20, 1.02-1.42) and a smoking mother and/or father (1.20, 1.02-1.40) were associated with the risk of asthma. CONCLUSIONS Our results are in line with the so-called 'hygiene hypothesis', which emphasizes the role of environmental factors in addition to a genetic predisposition in the development of atopic diseases. Research on factors associated with atopic diseases can facilitate decisions on preventive strategies. Further studies are needed to explore trends in prevalence and risk factors for atopic diseases.

Abstract
BACKGROUND The prevalence of allergic rhinitis (AR) is increasing worldwide. Allergic diseases develop in susceptible subjects when they are exposed to specific environmental factors. OBJECTIVE We analyzed changes in the prevalence of AR and identified genetic and environmental factors in early childhood that affect risk. METHODS We used the International Study of Asthma and Allergies in Childhood questionnaire to collect data on AR, allergies, and environmental exposures from 4554 elementary school students from 5 areas of Seoul, Korea, in 2008. We also obtained DNA from 1050 subjects from 1 area of Seoul for genotype analysis of IL13. RESULTS We identified genetic and environmental factors during infancy and early childhood that increased the risk for current AR (resulting in a diagnosis of AR and AR symptoms in the past 12 months) in elementary school-aged children. These included allergic disease in parents and antibiotic use in infants, allergic disease in parents and exposure of infants to mold, and allergic disease in parents and moving an infant to a newly built house. The risk of current AR also increased in subjects with GA or AA at nucleotide 2044 in IL13 who had been exposed to mold in the home during infancy (adjusted odds ratio, 3.27; 95% CI, 1.75-6.11) compared with subjects who had GG at this position and had not been exposed to mold (adjusted odds ratio, 3.27; 95% CI, 1.75-6.11). CONCLUSION The prevalence of AR is increasing in Korean children. Children with a family history of allergic disease and exposure to specific environmental risk factors during infancy are more likely to have AR. Children with GA or AA at IL13(+2044) are at increased risk for AR when exposed to mold in the home during the first year of life.

Abstract
AIM To investigate prevalence, time trends and factors associated with rhinitis and rhinoconjunctivitis not related to acute infections in New Zealand. METHODS The International Study of Asthma and Allergies in Childhood (ISAAC) surveyed children aged 6-7 and 13-14 years for symptoms of these conditions. Five New Zealand centres were surveyed on two occasions (Phase One and Phase Three) 8-10 years apart. In Phase Three, questions were included on environmental factors, which might be associated with rhinoconjunctivitis. We report findings related to symptoms of rhinoconjunctivitis among 24 190 New Zealand children. RESULTS Symptoms of rhinoconjunctivitis in the past year were reported in 11.4% of 6- to 7-year-old children and 18% of 13- to 14-year-old adolescents in Phase Three compared with 9.5 and 19.1%, respectively, in Phase One. Severe symptoms of rhinoconjunctivitis were reported in 0.5% of children and 0.8% of adolescents. Current symptoms were more common in males at 6-7 years and in females of 13-14 years, and Māori and Pacific Island ethnic groups had higher prevalence compared with those of European descent, especially in the older age group. For immigrant children, there was a very strong positive relationship between symptoms and length of time resident in New Zealand, supporting the probable importance of environmental factors. A positive association was found between symptoms and use of paracetamol in infancy or in the last year, and weaker associations were noted for antibiotic use, exercise, and regular pasta ingestion. CONCLUSIONS Further study of environmental factors is recommended.

Abstract
An assessment of the prevalence of dampness and mold in European housing stock was carried out. It is based on general indicators of dampness and mold in dwellings reported in the literature. The assessment relies on recent studies, taking into account regional and climatic differences, as well as differences in study design, methodology, and definitions. Data were available from 31 European countries. Weighted prevalence estimates are 12.1% for damp, 10.3% for mold, 10.0% for water damage, and 16.5% for a combination of any one or more indicators. Significant (up to 18%) differences were observed for dampness and mold prevalence estimates depending on survey factors, region, and climate. In conclusion, dampness and/or mold problems could be expected to occur in one of every six of the dwellings in Europe. Prevalence and occurrence of different types of problems may vary across geographical areas, which can be partly explained by differences in climate.

Abstract
OBJECTIVE To propose a comprehensive set of confounders and effect modifiers that should be considered in epidemiologic investigations. METHODS Two reviewers independently critiqued studies included in a recent systematic review and extracted data on the confounders and effect modifiers that were considered and the approaches used to justify inclusion. RESULTS Of the 62 studies reviewed, 20 were cohort, 16 case-control, 25 cross-sectional studies, and one ecologic study. All cohort, cross-sectional, and ecologic studies had some adjustment for confounding or consideration of effect modification, but this was only the case for 7/16 (44%) case-control studies. Of the 53 studies that considered confounding or effect modification, 39/53 (74%) gave no justification for the inclusion of the variables considered. Studies that justified the inclusion of the variables did so based on empirical evidence (n = 10), conceptual justification (n = 7), or a combination of the two (n = 3). Confounding was handled mainly by using regression modeling, but some case-control studies utilized matching and anova. Ten studies handled effect modification by stratification, eight tested for interaction, and five used both strategies. CONCLUSIONS We have found substantial shortcomings in the handling of confounding and effect modification in studies of diet and development of childhood asthma/allergies. Selection of variables should be based on conceptual considerations and empirical evidence. Using this approach, we have proposed a comprehensive set of confounders and effect modifiers that need to be considered in future studies.

Abstract
OBJECTIVE Allergic rhinitis is one of the most frequent chronic diseases among children. The objective of the study was to assess the prevalence of rhinoconjunctivitis and determine clinical, social and environmental associated factors, among school children aged 6-7 years and adolescents aged 13-14 years in Bogotá, Colombia. METHODS We used ISAAC (International Study of Asthma and Allergies in Childhood) phase III study methodology and questionnaire for design and data collection, and we did a secondary analysis of these data. The sample consisted of 3830 registers from adolescents between 13 and 14 years old and 3256 registers from children between 6 and 7 years. RESULTS The prevalence of rhinoconjunctivitis symptoms in the last year was 17.2% (95% CI, 15.9-18.5) in children vs. 24.9% (95% CI, 23.6-26.3) in adolescents. In both groups there was a female predominance in children (17.8% vs. 16.5%), and in the teenagers group (28.0% vs. 21.4%), though the differences were not statistically significant. The factors associated with rhinoconjunctivitis in the group of 6-7 years where: asthma [OR 3.9; (95% CI, 2.8-5.4)], atopic dermatitis [OR 2.3; (95% CI, 1.7-3.1)], use of acetaminophen in the last year [OR 2.6; (95% CI, 1.4-4.9)], use of antibiotics in the first year of live [OR 1.7; (95% CI, 1.3-2.3)], higher maternal education [OR 1.5; (95% CI, 1.0-2.3)] and cesarean delivery [OR 1.6; (95% CI, 1.2-2.1)]. Among the 13-14 year age-group, factors associated with rhinoconjunctivitis included: asthma [OR 2.6; (95% CI, 2.0-3.4)], atopic dermatitis [OR 1.8; (95% CI, 1.4-2.3)], use of acetaminophen in the last year [OR 1.8; (95% CI, 1.4-2.4)], consumption of fast-food three times or more per week [OR 1.5; (95% CI, 1.2-2.0), ever smoked [OR 1.4; (95% CI, 1.2-1.7)] and meat consumption was protective factor [OR 0.7; (95% CI, 0.5-0.9)]. CONCLUSION In both studied groups, the estimated prevalence of rhinoconjunctivitis symptoms was relatively high. Future in-depth research is needed to assess the complex interactions between allergic rhinoconjunctivitis symptoms and social and environmental factors.

Clin Exp Allergy 2011; 42:186-207. [PMID: 22092947 DOI: 10.1111/j.1365-2222.2011.03891.x] [Citation(s) in RCA: 147] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2011] [Revised: 09/01/2011] [Accepted: 09/02/2011] [Indexed: 11/30/2022]
Abstract
BACKGROUND There is comparatively little information in the public domain on the diversity in prevalence and triggers/factors associated with allergic rhinitis (AR) or allergic rhinoconjunctivitis (AR/C) in countries beyond western-Europe and North America. OBJECTIVE To review the prevalence and the sensitizing agents/triggers and factors associated with AR/C in several countries in Africa, the Asia-Pacific region, Australia, Eastern Europe, Latin America, Middle East and Turkey. METHODS Articles published in English in peer-reviewed journals were assessed and selected for further review, following an extensive literature search using the Medline database. RESULTS This review demonstrated that prevalence of AR and AR/C in these regions has predominantly been investigated in children; with studies indicating wide inter- and intra-regional variations ranging from 2.9% AR and 3.8% AR/C in 10-18-years-old children from one region in Turkey to 54.1% AR and 39.2% AR/C in 13-14-years-old children in one region in Nigeria. Moreover, the prevalence of AR and AR/C has increased markedly over the last decade particularly in some of the more affluent African countries, China-Taiwan and several Middle East countries, likely as a consequence of improved living standards leading to increased exposure to multiple traditional and non-traditional sensitizing agents and risk factors similar to those noted in western-Europe and North America. CONCLUSIONS AND CLINICAL RELEVANCE Our findings suggest that the greater diversity in prevalence of AR or AR/C in populations in these regions is in contrast to the lower diversity of AR or AR/C in the 'western populations (USA and Europe), which tend to be more uniform. This review provides a comprehensive database of the important allergens and triggers which are likely to influence the prevalence of allergic rhinitis in these diverse regions, where the prevalence of allergic rhinitis is increasing and its adverse impact on the quality of life of affected individuals is increasingly recognised.

Abstract
BACKGROUND Epidemiologic studies suggest that deficiencies of the nutrients selenium; zinc; vitamins A, C, D, and E; and low fruit and vegetable intake may be associated with the development of asthma and allergic disorders. OBJECTIVES To investigate the evidence that nutrient and food intake modifies the risk of children developing allergy. METHODS We systematically searched 11 databases. Studies were critically appraised, and meta-analyses were undertaken. RESULTS We identified 62 eligible reports. There were no randomized controlled trials. Studies used cohort (n = 21), case-control (n = 15), or cross-sectional (n = 26) designs. All studies were judged to be at moderate to substantial risk of bias. Meta-analysis revealed that serum vitamin A was lower in children with asthma compared with controls (odds ratio [OR], 0.25; 95% CI, 0.10-0.40). Meta-analyses also showed that high maternal dietary vitamin D and E intakes during pregnancy were protective for the development of wheezing outcomes (OR, 0.56, 95% CI, 0.42-0.73; and OR, 0.68, 95% CI, 0.52-0.88, respectively). Adherence to a Mediterranean diet was protective for persistent wheeze (OR, 0.22; 95% CI, 0.08-0.58) and atopy (OR, 0.55; 95% CI, 0.31-0.97). Seventeen of 22 fruit and vegetable studies reported beneficial associations with asthma and allergic outcomes. Results were not supportive for other allergic outcomes for these vitamins or nutrients, or for any outcomes in relation to vitamin C and selenium. CONCLUSION The available epidemiologic evidence is weak but nonetheless supportive with respect to vitamins A, D, and E; zinc; fruits and vegetables; and a Mediterranean diet for the prevention of asthma. Experimental studies of these exposures are now warranted.

Abstract
The authors assessed the relation between exposure to dampness and molds in dwellings and the development of allergic rhinitis in childhood in a 6-year, population-based prospective cohort study of 1,863 children aged 1-7 years at baseline in 1991 (follow-up rate, 77%) from Espoo, Finland. The studied exposures were history of water damage, presence of moisture and visible mold, and perceived mold odor in the home, based on parent-administered questionnaire. A total of 246 (13.2%) children developed physician-diagnosed allergic rhinitis during the study period, resulting in an incidence rate of 440 cases per 10,000 person-years (95% confidence interval (CI): 387, 499). In logistic regression adjusting for confounding, any mold or dampness exposure indicator at baseline (adjusted odds ratio = 1.55, 95% CI: 1.10, 2.18), at follow-up (adjusted odds ratio = 1.62, 95% CI: 1.21, 2.18), or both (adjusted odds ratio = 1.96, 95% CI: 1.29, 2.98) was an important independent determinant of the risk of allergic rhinitis. Of the individual indicators, water damage and moisture on the surfaces were consistent determinants of allergic rhinitis. The results of this cohort study, which assessed exposure before the onset of allergic rhinitis, strengthen considerably the evidence of the role of indoor dampness problems as determinants of allergic rhinitis in children.

Abstract
BACKGROUND Rhinoconjunctivitis (RC) is regarded as the most common chronic disease of childhood; however, the currently available epidemiological studies on prevalence, burden, and risk factors of RC are insufficient. This analysis aimed to investigate potential risk factors, symptom frequency, and burden of RC. METHODS Using the International Study of Asthma and Allergies in Childhood Phase II questionnaires, 6963 elementary school children aged 9-11 years were surveyed in five different city centers of Turkey. All participants were skin-prick tested with common aeroallergens. RESULTS The prevalence of ever rhinitis, physician-diagnosed rhinitis, current rhinitis, and current RC were 51.6, 31.0, 43.5, and 23.1%, respectively; 19.8% of children with RC symptoms were atopic to at least one allergen. Among students with RC symptoms, 42.2, 23.9, 35.8, and 28.2% reported moderate-severe interference of daily activities, at least 1 day of absence from school, visit to a health care professional, and any drug usage for rhinitis, respectively. Nasal decongestants and oral antihistamines were the most frequently used treatment. Approximately 70% of RC patients reported perennial symptoms and 42.8% were classified as mild to intermittent. Multivariate logistic regression analysis revealed family history of asthma and/or allergic rhinitis (odds ratio [OR] = 1.863; confidence interval, [CI] = 1.583-2.191; p < 0.001), living in a house with mold and dampness in the 1st year of life (OR = 1.651; CI = 1.356-2.01; p < 0.001), maternal smoking in pregnancy (OR = 1.425; CI = 1.089-1.864; p = 0.011), low monthly income (OR = 1.685; CI = 1.422-1.998; p = 0.001), current wheezing (OR = 2.543; CI = 2.151-3.006; p = 0.001), and current atopic eczema (OR = 2.503; CI = 1.96-3.196; p = 0.001) as significant risk factors for current RC. CONCLUSION Along with the high prevalence of RC in childhood, underdiagnosis and undertreatment of the disease are also frequent. The socioeconomic burden of the disease can be reduced by increasing awareness and proper diagnosis/treatment.

Abstract
OBJECTIVE There is growing evidence that the prevalence of allergic diseases is increasing, especially among children. The aim of this study was to evaluate the incidence and risk factors of allergic rhinitis in 6-12-year-old schoolchildren in Budapest. METHODS A total of 6335 children aged between 6 and 12 years attending 21 randomly selected primary schools in Budapest were surveyed in September 2007 by using a questionnaire consisting in part of questions compiled by the International Study of Asthma and Allergies in Childhood and in part of questions based on our own experience. RESULTS 3933 of the questionnaires (1976 M/1957 F) were appropriately completed by the parents. The prevalence of current allergic rhinitis was 14.9% (n=530), that of physician-diagnosed allergic rhinitis was 11.6% (n=413), and that of cumulative allergic rhinitis was 26.5% (n=943). Male gender (p<0.001), family history of atopy (p<0.001), eczema (p<0.001), urticaria (p<0.001), itchy-watery eyes (p<0.001), coughing (p<0.001), wheezing (p<0.001), a hearing impairment (p<0.001), itching of the palate (p<0.001), frequent upper airway infection (p<0.001), frequent rhinosinusitis (p<0.001), a history of tonsillectomy (p<0.01), a history of adenoidectomy (p<0.001), antibiotics given in the first year of life (p<0.001), paracetamol given in the first year of life (p<0.001), living in a green area (p<0.001), the consumption of soft drinks containing preservatives or colourants (p<0.04), feather bedding (p<0.01), living in a house made of concrete (p<0.001), living not far from an air-polluting factory or mine (p<0.001), and long-lasting disease before the appearance of the allergy (p<0.001) were all significant factors involving an increased risk of allergic rhinitis symptoms. The frequent consumption of tomatoes, nuts, margarine and butter significantly affected the cumulative allergic rhinitis prevalence. RESULTS Overall, the 12-month prevalence of allergic rhinitis in these 6-12-year-old children in Budapest was 14.9%, which is higher than reported from other European countries. Our findings differ from those on other cohorts in that exposure to ragweed and to indoor environmental factors in concrete housing estates in Budapest may be of particular importance as concerns allergic sensitization.

Abstract
Studies have reported contradictory effects of cat and dog exposure on allergy, resulting in inconsistent recommendations on animal avoidance. We conducted a systematic review of observational studies published in English from 2000 to January 2009. It shows in this review that the reported exposure-response relationships are contradictory. A total of 17 and 13 birth cohort studies on cat and dog exposure, respectively, are included in the review. Most of the birth cohort studies found that cat or dog exposure in early life had no effect on the development of asthma or wheezing symptoms and dog exposure during infancy was found to protect children from developing sensitization against aeroallergens. A total of 7 and 6 prospective studies in school-age children or adults on cat and dog exposure, respectively, are included in this review and most of these studies suggested an inverse association between cat exposure and asthma and wheezing symptoms. As for cross-sectional studies, 26 and 21 studies on cat and dog exposure, respectively, are included in this review, which cover a broad range of age groups and geographical areas, and reported inconsistent results. The evidence summarised in this systematic review needs to be interpreted with caution, the inconsistent study results may be due to study design, exposure assessment, and avoidance measure. The exposure-response relationships may also alter in geographical areas where the community prevalence of cats and dogs are significantly different. However, as the evidence of the effects of pet keeping on subsequent development of asthma or allergic diseases presented in this review are not overwhelmingly strong, the decision of whether to keep a cat or a dog in the family should be based on arguments other than the concern of developing asthma and allergy.

Abstract
OBJECTIVE Psychiatric symptoms are observed more commonly in mothers of children with allergic disease compared to the general population. In our study, we aimed to compare family functioning and anxiety parameters in mothers of children diagnosed allergic rhinitis and healthy controls. METHODS Study group consisted of 82 mothers of 7-15 years old children with allergic rhinitis. Control group consisted of 70 mothers of children with no chronic diseases. State-Trait Anxiety Inventory (STAI) and McMaster Family Assessment Device (FAD) scales was obtained from participants. RESULTS Anxiety scores in mother of children with allergic rhinitis were significantly higher than the ones in the control group (50+/-7.54, 32+/-5.44, p=0.02, respectively). Family assessment scores were higher in mother of children with allergic rhinitis when compared to the control group but did not reach statistical significance (1.89+/-0.12, 1.87+/-0.95, p=0.19, respectively). Smoking status at home and jobless father were found to have a significant impact on the evaluation scale in mothers in the case group. CONCLUSION Psychiatric symptoms observed in mothers of children with allergic rhinitis might be associated with child disease and the functioning of the entire family rather than features of the mother alone. Having a child with allergic rhinitis does not affect family functions according to the mother's aspect.

Abstract
Speculation persists as to the possible role, if any, of dietary antioxidants in allergic disease. While it has been hypothesized that the recent increase in allergic disease is a consequence of declining dietary antioxidant intake, an alternative hypothesis proposes that the increase in allergic disease is due to increasing antioxidant intake. Dietary trends are conflicting; the intake of some antioxidants has declined, for others intakes are likely to have increased. Animal model studies demonstrate that antioxidant supplementation at the time of primary and subsequent allergen exposure attenuates allergic inflammatory responses. The data from human studies are less clear. Observational epidemiological studies of humans are beset by several methodological limitations associated with the assessment of diet and predominantly focus on asthma. Most observational studies report potentially beneficial associations between dietary antioxidants and allergic outcomes, but a small minority report potentially adverse associations. Human intervention studies suggest that single antioxidant supplements confer minimal, if any clinical benefit in adults with asthma, however, there is still scope for studies in children, atopic dermatitis, allergic rhinitis (AR) and of antioxidant combinations. More recently, it has been suggested that dietary antioxidants in the developmental context of fetal and infant development influence the development childhood asthma and atopic sensitization possibly by affecting the first interactions between the neonatal immune system and allergens. While a small number of birth cohort studies have reported potentially beneficial associations between maternal intake of some antioxidants during pregnancy and childhood asthma, there is very limited data suggesting associations between maternal antioxidant intake and childhood atopic dermatitis and AR. The available epidemiological, animal, molecular and immunological data suggest that there are associations between antioxidants and asthma and to a much lesser extent, atopic dermatitis and AR. However, the exact nature of the relationships and the potential for therapeutic intervention remain unclear.

Abstract
BACKGROUND Exposure to pets has been implicated as a risk factor for asthma. However, this relation has been difficult to assess in individual studies because of the large potential of selection bias. We sought to examine the association between exposure to furry pets and asthma and allergic rhinitis by means of a meta-analysis. METHODS We retrieved studies published in any language by searching systematically Medline (1966-March 2007), Embase, LILACS and ISI Proceedings computerized databases, and by examining manually the references of the original articles and reviews retrieved. We included cohort and case-control studies reporting relative risk estimates and confidence intervals of exposure to cats, dogs and unspecified furry animals and subsequent asthma and allergic rhinitis. We excluded cross-sectional studies and those studies that did not measure exposure but rather sensitization to pets. RESULTS Thirty-two studies were included. For asthma, the pooled relative risk related to dog exposure was 1.14 (95% CI 1.01-1.29), that related to exposure to any furry pet was 1.39 (95% CI 1.00-1.95). Among cohort studies, exposure to cats yielded a relative risk of 0.72 (95% CI 0.55-0.93). For rhinitis, the pooled relative risk of exposure to any furry pet was 0.79 (95% CI 0.68-0.93). CONCLUSIONS Exposure to cats exerts a slight preventive effect on asthma, an effect that is more pronounced in cohort studies. On the contrary, exposure to dogs increases slightly the risk of asthma. Exposure to furry pets of undermined type is not conclusive. More studies with exact measurement of exposure are needed to elucidate the role of pet exposures in atopic diseases.

Abstract
AIM This paper explores the possible association between antibiotics prescribed in infancy and allergic disorders, mainly eczema and asthma, in childhood. BACKGROUND No-one fully understands why childhood asthma and eczema have become so common. Some authorities suggest that there may be an association between eczema and asthma and antibiotics prescribed in childhood; however, others disagree. METHOD/EVALUATION: The available literature was reviewed to examine the links between prescribed antibiotics and childhood eczema and asthma. FINDINGS/KEY ISSUE: Some, but not all, research indicates that antibiotic administration in pregnancy, childbirth or infancy may be linked to childhood asthma and eczema, but much uncertainty remains. None of the papers identified stated the doses of antibiotics prescribed. In addition, we were unable to locate studies reporting the interactions between antibiotics and the developing immune system. CONCLUSION Health care professionals should be selective when prescribing antibiotics. Further prospective work is needed to guide the prescribing of antibiotics in childbirth and infancy.
