“…Since the allergic component of asthma seems to be important, consideration should be given to its evaluation during diagnosis. Additionally, results of this work support the increasing evidence that the prevalence of asthma and other allergic diseases in Latin America is high [ 26 ], even though the climate and hygiene conditions are different than those of industrialized countries. Future research in the field should look for common risk factors acting at different times in developed and developing countries.…”

“…The Isaac III study in Bogota, however, found that asthma symptoms were correlated with the presence of a cat in the home, higher maternal education, watching televison 1 to 2 hours per day, and the use of acetaminophen and antibiotics in the last year [ 18 ]. In that same study, rhinoconjunctivitis symptoms were associated with previous acetaminophen and antibiotic use, and higher maternal education and cesarean birth [ 26 ]. Additional risk factors in Latin America have also been postulated and described in detail by Cooper et al elsewhere [ 27 , 28 ].…”

BackgroundWhile it is suggested that the prevalence of asthma in developed countries may have stabilized, this is not clear in currently developing countries. Current available information for both adults and children simultaneously on the burden and impact of allergic conditions in Colombia and in many Latin American countries is limited. The objectives of this study were to estimate the prevalence for asthma, allergic rhinitis (AR), atopic eczema (AE), and atopy in six colombian cities; to quantify costs to the patient and her/his family; and to determine levels of Immunoglobulin E (IgE) in asthmatic and healthy subjects.MethodsWe conducted a cross-sectional, population-based study in six cities during the academic year 2009–2010. We used a school-based design for subjects between 5–17 years old. We carried out a community-based strategy for subjects between 1–4 years old and adults between 18–59 years old. Serum samples for total and antigen-specific (IgE) levels were collected using a population-based, nested, case–control design.ResultsWe obtained information on 5978 subjects. The largest sample of subjects was collected in Bogotá (2392). The current prevalence of asthma symptoms was 12% (95% CI, 10.5-13.7), with 43% (95% CI, 36.3-49.2) reporting having required an emergency department visit or hospitalization in the past 12 months. Physician diagnosed asthma was 7% (95% CI, 6.1-8.0). The current prevalence of AR symptoms was 32% (95% CI, 29.5-33.9), and of AE symptoms was 14% (95% CI, 12.5-15.3). We collected blood samples from 855 subjects; 60.2% of asthmatics and 40.6% of controls could be classified as atopic.ConclusionsIn Colombia, symptom prevalence for asthma, AR and AE, as well as levels of atopy, are substantial. Specifically for asthma, symptom severity and absence from work or study due to symptoms are important. These primary care sensitive conditions remain an unmet public health burden in developing countries such as Colombia.

“…The majority of the studies recruited children from an urban background. Fourteen studies assessed both children (aged around 6-7 years) and adolescents (aged around 13-14 years), and provided the prevalence stratified by age [9,18,19,20,21,22,23,24,25,26,27,28,29,30]. …”

Background: A sex-related switch in the prevalence of asthma from childhood (male predominance) to adulthood (female predominance) has been described, but for allergic rhinitis this remains unclear. We aimed to examine sex- and age-group-specific differences in allergic rhinitis prevalence by systematically evaluating studies from across the globe. Methods: A systematic search of MEDLINE and Embase for population-based cross-sectional studies was performed regardless of the language of publication. The search was restricted to the present millennium (2000 to June 2014). Study quality was defined by the sampling method, response rate, sample size, and data collection method. To assess sex differences in the prevalence of self- or parent-reported symptoms of rhinitis, calculated pooled estimates of the male-female ratio (MFR) were obtained using random-effects model meta-analyses due to heterogeneity. A meta-regression analysis was also performed. Results: Out of 6,539 publications identified, 67 cross-sectional population-based studies (291,726 males and 301,781 females) were included in our meta-analysis. In children (<11 years of age) significantly more boys than girls had rhinitis symptoms (MFR 1.21, 95% CI 1.17-1.25), whereas in adolescents (11 to <18 years of age) males were significantly less often affected than females (MFR 0.90, 95% CI 0.85-0.95). No sex-specific prevalence difference was observed in adults (MFR 0.96, 95% CI 0.83-1.17). These findings were consistent in all continents except in Asia, where the male predominance remained beyond childhood. Conclusions: The male predominance of rhinitis prevalence in childhood changed towards a female predominance in adolescence across the globe, except in Asia. Longitudinal studies are needed to confirm these cross-sectional data and examine possible determinants and underlying mechanisms.

“…Unlike our study, however, most of those prior studies did not account for paracetamol use, which has been linked to asthma and allergic rhino-conjunctivitis in young children 29, 30 . Likewise, antibiotic use in the first year of life was associated with current symptoms of allergic rhino-conjunctivitis among children aged 6–7 years old in New Zealand (OR=1.94, 95% CI=1.69, 2.24) 31 and Colombia (OR=1.7, 95% CI=1.3, 2.3) 32 , but those studies did not account for bronchiolitis 31, 32 or paracetamol use 31 in early life. Although less studied, the gut virome includes eukaryotic viruses and bacterial viruses, which may interact with bacteria to affect host immune system and susceptibility to viral infection 21 .…”

Background Little is known about differential effects of antibiotic use on allergic diseases in rural versus urban environments. Objective: To examine whether area of residence in the first year of life modifies the relation between antibiotic use in early life and allergic diseases during childhood. Methods Cross-sectional study of allergic diseases in 1,517 children (ages 6–7 years) attending 101 schools in urban and rural areas of San Francisco (Córdoba, Argentina). Current asthma, wheeze, and allergic rhino-conjunctivitis were defined on the basis of responses to a validated questionnaire from the International Study of Asthma and Allergies in Childhood (ISAAC). Multivariate logistic regression was used for the analysis of antibiotic use and allergic diseases. Results After adjustment for paracetamol use, bronchiolitis, and other covariates, antibiotic use in the first year of life was associated with increased odds of current wheeze (odds ratio [OR]=1.8, 95% confidence interval [CI]=1.3–2.6) and allergic rhino-conjunctivitis (OR=1.9, 95% CI=1.3–2.7). After stratification by area of residence, antibiotic use was associated with current wheeze (OR=2.4, 95% CI=1.5–4.0) and allergic rhino-conjunctivitis (OR=2.1, 95% CI=1.3–3.4) among children who lived in an urban area in their first year of life, but not among those who lived in a rural area in their first year of life. Conclusions Early-life antibiotic use is associated with current wheeze and allergic rhino-conjunctivitis in Argentinean children who lived in urban areas during their first year of life. Exposure to a rural environment early in life may protect against the adverse effects of antibiotics on atopic diseases in children.
