In-vitro data suggest that long-acting beta2-agonists may have a neutrophil-stabilising effect. A reduction in airway wall eosinophil number following introduction of salmeterol in persistent asthma has previously been described. There is currently interest in the "neutrophil system" in asthma, and thus the aim of the present study was to investigate the effect of salmeterol on interleukin (IL)...

Objective: To evaluate the stature growth rate (GR) and the weight gain of prepubertal asthmatic children. Method: A retrospective cohort study evaluating medical records of 85 children diagnosed with asthma, aged less than 9 years, of both sexes, with at least one year of follow-up in the allergy outpatient clinic. The data on the disease, weights and heights were collected through a standa...

Increased asthma severity is not only associated with enhanced recurrent hospitalisation and mortality but also with higher social costs. Most cases of asthma are atopic in nature, with the trigger for acute asthma attacks and chronic worsening of inflammation being allergens inducing an immune response through immunoglobulins of IgE class. Currently antiinflammatory treatments are effective fo...

Control and severity of asthma are two different but complementary concepts. The severity of asthma could influence the control over time. The aim of this study was to demonstrate this relationship. A total 365 patients with persistent asthma (severity) were enrolled and followed-up prospectively. Data were analysed using a continuous time homogeneous Markov model of the natural history of asth...

The last few decades have seen a rise in the prevalence of allergic diseases, including asthma and allergic rhinitis. The prevalence asthma is estimated to be around 300 million globally and around 35% in Europe and Australasia and 60 million people in the United States are affected by rhinitis. In India prevalence asthma is estimated to be around 2.38% and 20% to 26% people suffer from allergi...

BACKGROUND Exacerbations of asthma cause a substantial global illness burden. Adults with uncontrolled persistent asthma despite maintenance treatment require additional therapy. Since macrolide antibiotics can be used to treat persistent asthma, we aimed to assess the efficacy and safety of oral azithromycin as add-on therapy in patients with uncontrolled persistent asthma on medium-to-high do...

Insufficient use of anti-inflammatory drugs, such as inhaled corticosteroids and cromoglycate, may contribute to the disease burden associated with asthma. Conversely, aggressive treatment of mild disease may result in avoidable costs and/or adverse drug effects. The aim of this study was to determine the relationship between asthma severity and inhaled corticosteroid/cromoglycate use in a larg...

BACKGROUND Asthma is one of the most common chronic inflammatory diseases in developed countries. Susceptibility to asthma is associated with interaction between multiple genes and environmental factors. Several cytokines play a major role in the pathophysiology of the disease. OBJECTIVE We analyzed the distribution of cytokine gene polymorphisms in a group of patients with asthma and a contr...

BACKGROUND Asthma and rhinitis are frequent respiratory diseases in children and adults. Despite the increase in the aging population, there are few epidemiologic data on both diseases in the elderly. So far, no population-based study has analyzed the association between asthma and rhinitis symptoms and severity in this age group. This study aimed to estimate the prevalence of physician-diagnos...
