aspergillus species in indoor environments and their possible occupational and public health hazards
abstract the genus aspergillus, which consists of a few hundred opportunistic mold species found in various climatic conditions, causes diseases including localized infections, fatal diseases, allergic responses, and inhaled conidia in humans. herein, we present an overview of the most common diseases and allergic infections caused by aspergillus species and their associated health hazards in v...
The prevalence of allergic diseases, specially respiratory allergic diseases such as allergic rhinitis and asthma, has been increasing worldwide for the last 2 decades [1, 2]. Although avoidance of the responsible allergen, anti-inflammatory, and symptomatic treatment modalities has shown great efficacy in the treatment of allergic respiratory disorders, cessation of pharmacotherapy usually res...
Allergy today is a public health concern of pandemic proportions, affecting more than 150 million people in Europe alone. In view of epidemiological trends, the European Academy of Allergy and Clinical Immunology (EAACI) predicts that within the next few decades, more than half of the European population may at some point in their lives experience some type of allergy.Not only do allergic patie...
BACKGROUND Allergen-specific immunotherapy (AIT) is the only treatment able to change the natural course of allergic diseases. We aimed at investigating the clinical efficacy of SLITOR (Serbian registered vaccine for sublingual allergen specific immunotherapy). METHODS 7-18 years old children with allergic asthma and rhinitis were enrolled and addressed to the active (AIT plus pharmacological...
Contact (allergic) dermatitis is a skin disorder related to natural exposure to various allergens. Systemic contact dermatitis (SCD) describes a cutaneous eruption in response to systemic exposure to an allergen. The exact pathologic mechanism remains uncertain. Herein we describe a 36-year-old woman with symmetric systemic allergic contact dermatitis, unresponsive to conventional treatment, as...
the prevalence of allergic disorders has increased markedly throughout the world over the past three decades. it seems probable that the increased prevalence is real because longitudinal studies have shown a rapid exponential increase in allergic disor¬ders. in order to determine the prevalence of type 1 allergy in patients with allergic disorders in sistan-blouchestan province, in the southeas...
patients and methods in this cross sectional study, 295 volunteers with the signs and symptoms of allergic diseases who referred to the khuzestan jahad daneshgahi medical center in ahvaz during 2010 were investigated. all patients were subjected to skin prick test (spt) with common allergenic extracts. data were analyzed by spss-18 software using chi square test. results seventy subjects, compr...
Allergic asthma is a disease characterized by persistent allergen-driven airway inflammation, remodeling, and airway hyperresponsiveness. CD4(+) T-cells, especially T-helper type 2 cells, play a critical role in orchestrating the disease process through the release of the cytokines IL-4, IL-5, and IL-13. Allergen-specific immunotherapy (SIT) is currently the only treatment with a long-term effe...
BACKGROUND Allergen induced early phase airway response and airway plasma exudation are predominantly mediated by inflammatory mast cell mediators including histamine, cysteinyl leukotrienes (cysLTs) and thromboxane A2 (TXA2). The aim of the present study was to evaluate whether repeated allergen exposure affects early phase airway response to allergen challenge. METHODS A trimellitic anhydri...
BACKGROUND Exposure to airborne wheat allergen is a well-known cause of bakers' allergy and asthma. Airborne wheat allergen can be measured by enzyme immunoassays (EIAs) in extracts of inhalable dust samples, but only limited knowledge is available on the size distribution of wheat allergen-carrying particles. Recently, a new sampling medium, porous polyurethane foam, has been introduced for th...
