the clinical behavior of asthma varies with age at onset. this study was undertaken to identify associated markers of adult-onset allergic asthma (age ≥20 years).this cross-sectional study compared two groups: 58 patients with asthma onset at <20 years and 66 with onset at ≥20 years. they were compared depending on results of clinical history, and body mass index (bmi), aeroallergen sensitizati...

Background: Because of geographic variation and regional types of allergens, it is recommended that allergists identify common allergens in their area of activity. In the present study, the prevalence of respiratory allergens in patients with asthma and allergic rhinitis was investigated. Methods: This study is descriptive and retrospective. The required data of this study were extracted from ...

BACKGROUND During the latter half of the 20th century, the prevalence of asthma and many other allergic diseases has increased. Information on asthma prevalence trends among adults after 2010, especially regarding studies separating allergic asthma from non-allergic asthma, is lacking. OBJECTIVE The aim was to estimate prevalence trends of current asthma among adults, both allergic and non-al...

allergic diseases are frequent in children and their prevalence and severity differ in the different regions of the world. the association between pet ownership in childhood and subsequent asthma and sensitization is very controversial. in our survey conducted with standardized method (international study of asthma and allergies in childhood), 3200 children 6-7 years old were questioned regardi...

Background Allergic rhinitis is one of the most common types of rhinitis. Allergen avoidance is the most important way of preventing this disease. The present study is carried out to determine the frequency of common aeroallergens in patients with allergic rhinitis in Gorgan city by skin prick test (SPT) reactivity. Materials and Methods  In this cross-sectional study 270 patients referring t...

a positive association between acetaminophen intake and allergic diseases has recently been reported in developed countries with impaired oxidant/antioxidant balance and promotion of atopy as proposed underlying mechanisms. the aim of the study was to explore the relationship between acetaminophen intake and asthma, hay fever, and eczema in the republic of macedonia as a country with acetaminop...

allergic asthma is a multifactorial disease, influenced by genetic and environmental factors. recent family-based studies have revealed evidence for linkage of human chromosomes 5q31-33, 12q15-24, 11q13 and 15q23.6 as regions likely to contain genes related to asthma. among the candidate genes in these regions are the genes encoding for human interleukin-4, interleukin-13 and interleukin-16. to...

interleukin (il)-35 is a newly discovered suppressive cytokine and has been shown to alleviate  inflammatory  and  autoimmune  diseases.  the  purpose  of  this  study  was  to investigate immunomodulatory capacity of il-35 in patients with allergic asthma.il-35 mrna expression levels in peripheral blood mononuclear cells (pbmcs) were detected  by  quantitative  real-time  pcr  (qpcr).  the  fr...
