Background: Sensitization to inhaled allergens in children with bronchial asthma significantly affects asthma pathogenesis, severity and persistence into late childhood and adulthood. The present study determined the prevalence of sensitization to inhaled allergens in children with bronchial asthma and wheezing episodes in order to investigate the effect of positive sensitization on the severity and control of asthma symptoms and to screen for other associated allergic conditions. Methods: A cross-sectional study was conducted, including children between 6 months and 14 years of age attending the chest clinic of Al-Karak, south of Jordan, between November 2013 and February 2016. Skin prick tests (SPTs) using 11 standardized allergen extracts were conducted in 277 children. The severity of asthma was determined based on the Global Initiative for Asthma (GINA) assessment and the Childhood Asthma Control Test (C-ACT) in addition to the history of use of systemic steroids and hospital admissions within the past 12 months. Results: Sixty-seven percent of children with bronchial asthma reported sensitization to one or more of the inhaled allergens. The most common allergens were olive pollens (18%), cat fur (13.5%), and Dermatophagoides pteronyssinus (11.9%). There was a significant increase in allergen sensitization with age (p < 0.001). The most common concomitant allergic condition among children was allergic rhinitis (71.5%); however, allergic conjunctivitis was the only allergic condition that correlated with the skin test reactivity (p = 0.01). A family history of bronchial asthma was confirmed in 40.4% of children. Children with positive SPTs had lower ACT scores and reported more frequent use of systemic steroids and admissions to hospital within the past 12 months; however, this effect was not statistically significant (p > 0.05). Conclusions: Sensitization to inhaled allergens is highly prevalent in children with asthma and wheezing episodes in southern Jordan and may be correlated with the severity of the disease. Therefore, appropriate measures to recognize and avoid these allergens are highly recommended. Most children in our study suffered from concomitant allergic rhinitis, indicating that an appropriate diagnosis and treatment of allergic rhinitis could significantly improve asthma control and thus the quality of life of these children.

Abstract Background Globally, a surge in electronic cigarette (e-cigarette) use has been observed in recent years, with youth being the most susceptible group. Given their recent emergence, studies assessing the health consequences of using e-cigarettes and exposure to their secondhand aerosols (SHA) are limited. Hence, this study sought to assess associations between e-cigarette use and household exposure to SHA from e-cigarettes with asthma symptoms among adolescents. Methods A school-based cross-sectional study was conducted by enrolling high school students (n = 1565; aged 16–19 years) in Kuwait. Participants self-completed a questionnaire on tobacco products use (e-cigarettes and cigarettes) and asthma symptoms. Current e-cigarette use and cigarette smoking were defined as any use in the past 30 days. Household exposure to SHA from e-cigarettes in the past 7 days was reported as none (0 days), infrequent (1–2 days), and frequent (≥ 3 days). Asthma symptoms included current (past 12 months) wheeze, current asthma (history of clinical diagnosis and current wheeze and/or medication use), and current symptoms of uncontrolled asthma (≥ 4 attacks of wheeze, ≥ 1 night per week sleep disturbance from wheeze, and/or wheeze affecting speech). Associations were assessed using Poisson regression with robust variance estimation, and adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) were estimated. Results Among the analytical study sample (n = 1345), current e-cigarette use and cigarette smoking was reported by 369 (27.4%) and 358 (26.6%) participants, respectively. Compared to never e-cigarette users and never cigarette smokers, current e-cigarette users with no history of cigarette smoking had increased prevalence of current wheeze (aPR = 1.54, 95% CI 1.01–2.45) and current asthma (aPR = 1.85, 95% CI 1.03–3.41). Moreover, the frequency of exposure to household SHA from e-cigarettes was associated with asthma symptoms. For example, compared to those with no exposure to household SHA, frequent exposure to household SHA was associated with current wheeze (aPR = 1.30, 95% CI 1.04–1.59), current asthma (aPR = 1.56, 95% CI 1.13–2.16), and current uncontrolled asthma symptoms (aPR = 1.88, 95% CI 1.35–2.62). Conclusions E-cigarette use and their household SHA exposure were independently associated with asthma symptoms among adolescents. Hence, such observations indicate that e-cigarette use and passive exposure to their aerosols negatively impact respiratory health among adolescents.

BACKGROUND: Eczema, allergic rhinitis and asthma are common chronic allergic disorders in childhood.AIM: The aim of this study was to determine the prevalence of common allergic disorders among Iranian guidance schools students in Mazandaran Province, northern Iran.METHODS: This analytical cross-sectional study was performed on 3000 children aged 11‐14 years old during 2012‐13 according to ISAAC study. Of 3000 recruited children 1576 (52.54%) were female and 1424 (47.46%) were male. Data gathered by ISAAC first phase questionnaire analysed by SPSS software 20.RESULTS: The prevalence of wheezing, allergic rhinitis symptoms (sneezing and pruritus) and atopic dermatitis symptoms (pruritus skin lesion) were 30.5%, 30% and 15% respectively. History of pets contact and smoking was positive 6.6% and 36 % respectively. About 52% was born with caesarian section. There was wheezing in 32.5% during sport. The diagnosis of asthma, allergic rhinitis and eczema were 12.2%, 28.5% and 15% respectively. Eczema, asthma and allergic rhinitis were significantly more common in boys students (p < 0.05).CONCLUSIONS: The results of this study showed that asthma, allergic rhinitis and eczema have a high prevalence and they are more common in boys.

Introduction: Various initiatives and medications have been introduced to achieve better control of bronchial asthma. However total control according to Global Initiative for Asthma (GINA) remains elusive even at tertiary referral hospitals. Our study is to determine the level of asthma control (according to GINA 2009), Asthma Control Test (ACT) scores and the types of medications used among patients with bronchial asthma in a large tertiary hospital. Methods: A cross-sectional study of all patients with bronchial asthma who attended the Chest Clinic at Hospital Tengku Ampuan Afzan (HTAA) from 2009 to 2011. Patient demographics, self-administered ACT scores, GINA-defined level of asthma control and medications were documented. Results: 208 patients were recruited. There were 23.2%, 46.3% and 30.5% of patients with controlled, partly controlled and uncontrolled asthma respectively. The median ACT scores was 19 [inter quartile range (IQR) 6]. The most frequently used preventer therapy was inhaled long-acting β-agonist/corticosteroids (LABA/ICS) fixed-dose combination (61.7%), and 9.6% were not on preventer therapy. 75% of patients with controlled asthma were on LABA/ICS compared to 58.5% of the partly controlled and uncontrolled groups (p=0.039). Conclusion: The majority of the asthmatic patients attending the Chest Clinic at HTAA did not have GINA-defined controlled asthma. Patients with higher ACT scores had better control of asthma. There were more patients with controlled asthma who were on LABA/ ICS combination.

Background. Asthma and allergic rhinitis are highly prevalent conditions that cause major illness worldwide. This study aimed to assess the association between allergic rhinitis and asthma control in Peruvian school children.Methods. A cross-sectional study was conducted among 256 children with asthma recruited in 5 schools from Lima and Callao cities. The outcome was asthma control assessed by the asthma control test. A score test for trend of odds was used to evaluate the association between allergic rhinitis severity and the prevalence of inadequate asthma control. A generalized linear regression model was used to estimate the adjusted prevalence ratios of inadequate asthma control.Results. Allergic rhinitis was present in 66.4% of the population with asthma. The trend analysis showed a positive association between allergic rhinitis and the probability of inadequate asthma control (). It was associated with an increased prevalence of inadequate asthma control, with adjusted prevalence ratios of 1.53 (95% confidence interval: 1.19−1.98).Conclusion. This study indicates that allergic rhinitis is associated with an inadequate level of asthma control, giving support to the recommendation of evaluating rhinitis to improve asthma control in children.

Background: Several studies have shown variations in the prevalence of allergic rhinitis (AR) around the world, and different potential predisposing factors. More studies are needed on risk factors, specifically in developing countries. This study explored the association of several factors and AR among urban residents in six cities of Colombia. Methodology: A cross-sectional study and a nested case-control study were carried out between 2009 and 2010 involving two Colombian subpopulations: children/adolescents and adults. Cases were affirmative respondents to "In the past 12 months, have you (or your child) had a problem with sneezing or a running or blocked nose, when you (or your child) did not have a cold or the flu?" "Controls" were subjects who never had been diagnosed with asthma, AR or atopic eczema by a physician, and whom did not report any symptoms in the past twelve months. Weighted logistic regression was used to assess the association of different factors with case/control status. Results: Factors associated with AR in children/adolescents were family history of AR, acetaminophen consumption and high socioeconomic status. Among adults, family history of asthma, AR and atopic eczema, and cetaminophen consumption were associated with AR. Consumption of cereals among children/adolescents and eating eggs among adults showed protective associations. Conclusions: Our findings suggest the presence of previously unknown cultural, environmental and family factors associated with the presence of AR in Colombia.
