“…We reported previously that family ownership of domestic pets during early life, including during the pre-natal period, was associated with lower odds of atopic asthma by mid-childhood compared with no pet ownership [7], confirming findings from previous studies [8–10]. Conversely, we also found that pet ownership, particularly of rabbits and rodents, tended to be associated with higher odds of non-atopic asthma.…”

BackgroundAsthma is a heterogeneous condition and differential effects of pet ownership on non-atopic versus atopic asthma have been reported. The aim of this study was to investigate whether pet ownership during pregnancy and early childhood was associated with wheezing from birth to age 7 years and with lung function at age 8 years in a UK population-based birth cohort.MethodsData from the Avon Longitudinal Study of Parents and Children (ALSPAC) were used to investigate associations of pet ownership at six time-points from pregnancy to age 7 years with concurrent episodes of wheezing, wheezing trajectories (phenotypes) and lung function at age 8 years using logistic regression models adjusted for child’s sex, maternal history of asthma/atopy, maternal smoking during pregnancy, and family adversity.Results4,706 children had complete data on pet ownership and wheezing. From birth to age 7 years, cat ownership was associated with an overall 6% lower odds of wheezing (OR=0.94 (0.89-0.99)). Rabbit and rodent ownership was associated with 21% (OR=1.21 (1.12-1.31)) and 11% (OR=1.11 (1.02–1.21)) higher odds of wheezing, respectively, with strongest effects evident during infancy. Rabbit and rodent ownership was positively associated with a ‘persistent wheeze’ phenotype. Pet ownership was not associated with lung function at age 8 years, with the exception of positive associations of rodent and bird ownership with better lung function.ConclusionsCat ownership was associated with reduced risk, and rabbit and rodent ownership with increased risk, of wheezing during childhood. The mechanisms behind these differential effects warrant further investigation.

“…Specifically, while some studies have shown that exposure to pets within the first months or year of life increases the risk of subsequent allergic diseases, other studies have reported an inverse or no relationship between exposure to pets and risk of allergies (Chen et al, 2008;Wegienka et al, 2011;Lødrup Carlsen et al, 2012). In the current study, we found no significant correlation between pet ownership and AR severity.…”

ABSTRACT. The aims of the current study were to assess the clinical features of allergic rhinitis (AR) in children in Shanghai. Serumspecific IgE (sIgE) tests were performed on samples from patients with AR symptoms from January 2011 to December 2014. A disease-related questionnaire was completed after AR diagnosis. The allergen profile and clinical features of AR were analyzed. In total, 2713 AR patients were enrolled in this study. Dermatophagoides pteronyssinus was found to be the most common offending allergen in the study population. With increasing age, the prevalence of sIgE against inhalant allergens was significantly increased; however, the opposite trend was observed for food allergens. Additionally, the proportion of children with high levels of sIgE against D. pteronyssinus increased with age. Of the AR cases, 8.6% were classified as intermittent mild, 4.2% as persistent mild, 40.5% as intermittent moderate-severe, and 46.7% as persistent moderatesevere. A family history of allergies and a patient history of allergies within 6 months of birth were significantly associated with the duration and severity of AR symptoms. The occurrence of co-morbidities, such as allergic conjunctivitis, cough, and asthma, gradually increased from intermittent mild, persistent mild, and intermittent moderate-severe to persistent moderate-severe. The most frequently used drugs were topical corticosteroids and oral antihistamines, which were used by 86.7 and 79.0% of patients, respectively. These results confirm the adequacy of the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines for classifying AR patients, and advance the understanding of clinical features of AR in children in Shanghai, China.

Rev Alerg Mex. 2017;64 Supl 1:s11-s128. AbstractBackground: The need for a national guideline, with a broad basis among specialists and primary care physicians was felt in Mexico, to try unifying asthma management. As several high-quality asthma guidelines exist worldwide, it was decided to select the best three for transculturation. Methods: Following the internationally recommended methodology for guideline transculturation, ADAPTE, a literature search for asthma guidelines, published 1-1-2007 through 31-12-2015 was conducted. AGREE-II evaluations yielded 3/40 most suitable for transculturation. Their compound evidence was fused with local reality, patient preference, cost and safety considerations to draft the guideline document. Subsequently, this was adjusted by physicians from 12 national medical societies in several rounds of a Delphi process and 3 face-to-face meetings to reach the final version. Results: Evidence was fused from British Thoracic Society Asthma Guideline 2014, Global Initiative on Asthma 2015, and Guía Española del Manejo del Asma 2015 (2016 updates included). After 3 Delphi-rounds we developed an evidence-based document taking into account patient characteristics, including age, treatment costs and safety and best locally available medication. Conclusion: In cooperation pulmonologists, allergists, ENT physicians, paediatricians and GPs were able to develop an evidence-based document for the prevention, diagnosis and treatment of asthma and its exacerbations in Mexico.Keywords: Clinical practice guideline; Asthma; Asthmatic exacerbation; Bronchodilator; Inhaled corticosteroid; Spirometry; Immunotherapy. IntroducciónLa presentación de este documento muestra la importancia del asma en México por su alta prevalencia, pero también por su subdiagnóstico y tratamiento deficiente, que propician un mal control de los pacientes con asma, crisis más frecuentes y sintomatología activa. En consecuencia, el asma tiene un impacto socioeconómico considerable para el paciente y la sociedad en su conjunto, al igual que afecta la calidad de vida del paciente y su familia. En México, el paciente con asma puede recibir atención médica en los ámbitos pú-blico o privado, en los diferentes niveles de salud y por múltiples especialidades. Todas estas particularidades de la situación nacional indican la necesidad de un documento guía actualizado, con base amplia en múltiples gremios médicos, tanto de primer nivel de atención como de especialidad.El objetivo de la GUIMA 2017 es facilitar la reducción de la morbimortalidad por asma en México, no solo al mejorar el conocimiento acerca de esta patología, sino también al ayudar a la parte administrativa del Sector Salud a gestionar la selección y adquisición más precisa de los medicamentos necesarios para su tratamiento a nivel de la salud pública. Para tal fin se ofrecen lineamientos par...
