Clinical studies in asthma are not able to clear up all aspects of disease pathophysiology. Animal models have been developed to better understand these mechanisms and to evaluate both safety and efficacy of therapies before starting clinical trials. Several species of animals have been used in experimental models of asthma, such as Drosophila, rats, guinea pigs, cats, dogs, pigs, primates and equines. However, the most common species studied in the last two decades is mice, particularly BALB/c. Animal models of asthma try to mimic the pathophysiology of human disease...

BACKGROUND: Asthma is a heterogeneous chronic disease with different clinical expressions and responses to treatment. In recent years, several unbiased approaches based on clinical, physiological, and molecular features have described several phenotypes of asthma. Some phenotypes are allergic, but little is known about whether these phenotypes can be further subdivided. OBJECTIVE: We aimed to phenotype patients with allergic asthma using an unbiased approach based on multivariate classification techniques (unsupervised hierarchical cluster analysis)...

Atopic dermatitis (AD) is a chronic relapsing skin disease, characterized by flare-up due to the exposure to allergens in patients sensitized to them. Currently, therapy of AD is mainly based on symptomatic treatment and avoidance of irritating/allergenic factors, house dust mites being particularly important. Allergen immunotherapy (AIT) is suggested to be the only etiologic treatment, to modify the natural history of the disease. Areas covered: The aim of this review is investigating the putative role of AIT in AD through the evaluation of the most recent scientific literature...

India is the home to around 15-20 million asthmatics, and asthma prevalence is increasing in Indian metropolitan area, including Kolkata, West Bengal. Complex interactions of genetic and environmental factors are involved in asthma. Genome-wide search for susceptible loci regulating IgE response (atopy) have identified a candidate gene CD14 which is most important in the context of allergic responses of respiratory system. This study was aimed to investigate the role of house dust and house dust mites in development of bronchial asthma and to explore the possible association of candidate gene CD14 with disease manifestation among Kolkata patient population...

Background: The rising prevalence of atopic diseases implies a strong influence of environmental determinants. Epidemiological studies have identified several early life exposures that appear to influence the risk of developing atopic sensitization, but the combined influence of these exposures is unknown. We sought to estimate the proportion of atopy that could be attributed to common childhood exposures associated with atopic sensitization in adolescence and young adulthood. Methods: Atopic sensitization was measured by skin-prick tests for common aeroallergens in a population-based New Zealand birth cohort at ages 13 and 32 years...

BACKGROUND: Severe asthma in children is a global health problem. Severe therapy-resistant asthma (STRA) in children is a major clinical challenge due to persistent symptoms despite high doses of corticosteroids and results in high public health costs. Omalizumab (anti-IgE monoclonal antibody) has been described as an effective add-on therapy in these patients. The characteristics of children with STRA from low- and middle-income countries have scarcely been reported, and no real-life study has been published on the effects of omalizumab in this group of patients...

Pollen food allergy syndrome, is a type I cross-reaction mediated by IgE antibodies between an aeroallergen and a plant-derived antigen. Main symptoms are typically consist of localized oral symptoms such as numbness of the lip or mouth, itching, tingling and swelling of lips, tongue, palate and pharynx without systemic symptoms. Patients with seasonal allergic rhinitis, asthma or both more frequently experience pollen food allergy syndrome. Because most patients have mild symptoms and the improvement by avoiding food, the true incidence is unknown...
