Background and purpose: Asthma is a widespread chronic inflammatory disease of the airways that may become uncontrollable in severe subtypes, even with radical treatments. The present study attempts to determine the risk factors of the irreversible airway obstruction in severe asthma patients. Materials and methods: The study population were 72 patients with severe asthma, aged 16- 75 year old...
Background Cough variant Asthma (CVA) is defined as chronic cough without wheezing, and may be precursor of typical asthma. Thus, the diagnosis of CVA and early intervention can partly inhibit asthma progression.This study aimed to evaluate the role of spirometry in diagniosis of Cough variant Asthma in Iranian Children. Materials and Methods This descriptive observational study included a tota...
Objective(s): Asthma, the most frequent chronic respiratory disease, results from a complex interaction between multiple genes and environmental factors. To date, more than 100 candidate genes and single nucleotide polymorphisms (SNPs) have been reported to be associated with asthma. One of the discovered genes related to asthma is ADAM33. However, the relationship between ADAM33 gene polymorph...
results the overall prevalence of occupational asthma was 9.7%. this rate was 13.8% in the exposed group. logistic regression analysis showed that even after adjustment for confounding factors, a significant correlation existed between the frequency of occupational asthma and exposure to the produced dust particles (p < 0.05). in addition, age, work experience, body mass index, cigarette smokin...
Background & Objectives: There is geographic variability in the prevalence of asthma. Since there is inadequate of study on asthma in Iran, this study was performed in order to determine the prevalence of asthma in Kurdistan province. Methods: This cross-sectional study was performed as part of Iranian national survey to determine the risk factors of non communicable disease. Results: This ...
Background: Type 1 diabetes mellitus (T1DM) is by far the most common metabolic disease in children. Asthma is the most common chronic disease in pediatric population, and its prevalence has increased in the last decades. In this study, the prevalence of asthma among these children with T1DM has been described and its association with the demographic and clinical characteristics of Iranian chil...
Background: Asthma is the chronic inflammation of airways characterized by eosinophilic infiltration, mucus overproduction, airway hyper-responsiveness and airway remodeling. These changes are induced mostly by cytokines which are produced by T helper (Th) 2 cells. Recently, the role of interleukin-23 (IL-23) in the pathogenesis of adultallergic asthma has been studied. Objective: To explore IL...
background asthma is a chronic inflammatory air-way disease with increasing prevalence rate during the recent years. there are studies about the relationship between asthma and infectious diseases, including the association between asthma and helicobacter pylori. according to the latest studies, there is an epidemiological correlation between asthma prevalence and prevalence of h. pylori. objec...
Background and purpose: Asthma is a chronic inflammatory disease of the airways that is caused by hypersensitivity to environmental allergens. Symptoms of asthma include shortness of breath, airway hyper-responsiveness, wheezing, and cough. The disease might vary from a mild to severe and intermittent to chronic disease. Asthma is known as a multifactorial disease due to the interaction of gene...
Background & Aims: Asthma is one of the most common diseases worldwilde that can be prevented with optimal access to medical care. Since there is no data about the prevalence of risk factors of death caused by asthma in our region, the present study was performed to determine the prevalence risk factors of fatal asthma in asthmatic patients. Methods: This study was done on 200 asthmatic patient...
