Background: Asthma, allergic rhinitis and eczema as a common disorder in childhood, has many epidemiologic variations in different geographic areas. This study aimed at determining the prevalence of pediatric allergic disease in rural area of Babol. Methods: This analytical-cross sectional study was performed in 2012 by random sampling on 2 groups of children the first grou...
In the last 10 years much interest has been directed towards the relationship between upper and lower airways, in particular between rhinitis and asthma. Several clinical and epidemiological studies have shown a strong association between rhinitis and asthma. Rhinitis has been demonstrated to be a major risk for asthma occurrence [1], with rhinitis often preceding the onset of asthma both in at...
Allergic rhinitis is a common inflammatory condition affecting upper airways, nose, and eyes. Allergic rhinitis is a global health problem and is increasing in prevalence. Allergic rhinitis patients have often comorbidities asthma being one of the most common. Up to 40% of patients with allergic rhinitis have asthma and at least as many as 80% of asthma patients experience symptoms of allergic ...
Thymic stromal lymphopoietin (TSLP) potently induces deregulation of Th2 responses, a hallmark feature of allergic inflammatory diseases such as asthma, atopic dermatitis, and allergic rhinitis. However, direct downstream in vivo mediators in the TSLP-induced atopic immune cascade have not been identified. In our current study, we have shown that OX40 ligand (OX40L) is a critical in vivo mediat...
Low circulating levels of 25-hydroxyvitamin D [25(OH)D] are associated with chronic lung diseases such as asthma. However, it is unclear whether vitamin D is involved in disease pathogenesis or is modified by the inflammation associated with the disease process. We hypothesized that allergic inflammation decreases the level of circulating 25(OH)D and tested this using a mice model of house dust...
Background and Aims: Allergic disorders such as asthma, urticaria, eczema, and allergic rhinitis are common worldwide, and allergens are the most common etiology and exacerbating factors. So, This study aimed to find the allergens in these patients with skin prick tests. Materials and Methods: All the allergic cases referred to an allergic clinic in the north of Iran were visited by an allergi...
BACKGROUND Allergic rhinitis and asthma are chronic inflammatory conditions of airways sharing common pathophysiology. The two disorders have similar cellular responses, with different symptoms based on the differences in the physical structures involved. Studies have shown that allergic rhinitis has a major impact on asthma morbidity and that treating allergic rhinitis may also impact asthma c...
BACKGROUND Asthma is a heterogeneous chronic inflammatory condition characterised by reversible airway obstruction and hyperresponsiveness associated with underlying bronchial inflammation and structural changes. It represents an increasing health problem and is a huge burden on the patients, their families and society. The aim of the study was to characterise the adult asthmatic population att...
BACKGROUND Despite its high prevalence, early onset and chronic nature, the causes of asthma are not clearly established. The present study examined a plausible but untested relationship in the development of non-allergic asthma; an asthma phenotype closely linked to deprivation and other preventable risk factors. Our aim was to determine the mediating role of adiposity in the relationship betw...
A has generally been defined as a chronic disorder of the lung, with variable airway obstruction, wheeze/cough, and an underlying inflammatory process. However, considerable heterogeneity exists within the population of patients with asthma-like symptoms. Clinically, asthma is being categorized into eosinophilic, neutrophilic, atopic, non-atopic, early onset, and late onset; and aspirinor exerc...
