The aim of the present study was to investigate the epidemiological and fungal environmental profile in asthmatic patients. We conducted a prospective study involving 49 patients with allergic asthma. One hundred and forty-five clinical samples and 289 environmental samples were performed. Only 30 patients accepted to participate to the environmental study at their home. For specific IgE antibodies, ELISA assay was conducted for 21 patients. Molecular ITS sequencing was performed for 37 isolates. The frequency of attacks was significantly associated with the seasonality, which was closely related to climate (P=0...

BACKGROUND: Fragrances are well known to cause allergic contact dermatitis (ACD). Occupationally related cases occur, with certain groups being at higher risk. OBJECTIVE: To investigate the incidence of occupationally related cases of cutaneous fragrance allergy and to evaluate trends. METHOD: Data on incident cases of occupational ACD caused by fragrances between 1996 and 2015 (inclusive) reported to the EPIDERM surveillance scheme were analysed...

Furry mammals kept as pets, farm and laboratory animals are important allergen sources. The prevalence of sensitization to furred mammals appears to be increasing worldwide. Several mammalian allergens from diverse species are well characterized with regard to their molecular structure and immunogenicity, and some are already available for component-resolved allergy diagnostics. The distribution of various mammalian allergens has been extensively studied during the past few decades. Animal allergens were found to be ubiquitous in the human environment, even in places where no animals reside, with concentrations differing considerably between locations and geographical regions...

Background: Exposure to endotoxin is known to trigger airway inflammation and symptoms, and atopy may modify the relationship between endotoxin exposure and symptom development. Objective: To test the a priori hypothesis that atopic status modifies the relationship between endotoxin exposure and respiratory symptom development. Methods: A prospective study of laboratory workers at The Jackson Laboratories was conducted. Allergy skin testing was performed and population demographic and clinical information was obtained at baseline...

The growing use of silver nanoparticles (Ag-NPs) in consumer products raises concerns about their toxicological potential. The purpose of the study was to investigate the size- and coating-dependent pulmonary toxicity of Ag-NPs in vitro and in vivo, using an ovalbumin (OVA)-mouse allergy model. Supernatants from (5.6-45 µg/mL) Ag50-PVP, Ag200-PVP or Ag50-citrate-treated NR8383 alveolar macrophages were tested for lactate dehydrogenase and glucuronidase activity, tumor necrosis factor (TNF)-α release and reactive oxygen species (ROS) production...

BACKGROUND: Identifying risk factors is a key point for preventive strategies to reduce the incidence of COPD. The aim of this systematic review and meta-analysis was to determine the most important risk factors for COPD among adults in Chinese Mainland, so as to provide some precautions and interventions on this disease and preventing further recurrences. METHODS: A comprehensive literature review relating to risk factors for COPD through PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang database and VIP database was conducted before March 31, 2017...

Latex allergy emerged as an epidemic of anaphylaxis, occupational asthma, and clinical dilemmas in the 1980s. A systematic recognition, investigation, discovery, epidemiology, and prevention strategy followed. International attention and collaborations of investigators, government agencies, manufacturing, and health policy resulted in near elimination of a global epidemic. This article summarizes nearly 4 decades of work in control of this epidemic and focuses attention on future problems that still require resolution...

BACKGROUND: An increasing number of studies in children is highlighting the importance of transdermal routes of exposure to food allergens through damaged skin in the pathogenesis of food allergies. However, data on this in adults are limited. A few case-series studies has documented development of food allergy among kitchen workers with hand eczema after direct contact exposure to foods. METHODS: To explore the significance of hand eczema as a risk factor for food allergies in adults at the epidemiological level, we performed a cross-sectional web-based questionnaire survey on kitchen workers whose exposures were classed as occupational (cooks and food handlers, n = 1592) or non-occupational (housewives, n = 1915)...

Farmers are usually exposed to various inhaled allergens like pollens, mites, molds, and animal dander in their working environment which may lead to allergic rhinitis, asthma and urticaria. The purpose of this study was to identify sensitization to various aeroallergens in farmers and their occupational allergy symptoms. This cross sectional study included 103 male farmers and 100 non-farmer healthy controls. The work-related symptoms of farmers were recorded with a questionnaire. Spirometry and skin prick tests with 15 commercial allergen extracts were performed in both farmers and controls...

Exposure to bioaerosols in indoor animal farms associates with respiratory illnesses, but little is known about the immune modulation to chicken farmers. This study aimed to compare the general immunity of chicken farmers with those of control subjects with non-agricultural jobs. Blood taken from the farmers and controls was subjected to plasma IgE and IgG subclass measurements. Isolated peripheral blood mononuclear cells (PBMC) were stimulated and cytokine production was measured. Indoor total and respirable dust levels and their endotoxin (LPS) and aflatoxin (AF) levels in the farms were measured...

BACKGROUND: The relationship of enterovirus (EV) infection and Kawasaki disease (KD) is still unclear. The purpose of this study was to conduct a population-based cohort study to determine the relationship between KD and EV infection in Taiwan. METHODS: A population-based cohort study was conducted to analyze the children file (age <18 years) of the Taiwan National Health Insurance program between 2000 and 2008. In total, 285636 children with EV infection and 285636 children without EV infection were included and followed up...

Josje Arts, Ian Kimber
Azodicarbonamide (ADCA) is widely used by industry in the manufacture of a variety of products. ADCA has been classified as a respiratory allergen, and the purpose of this article was to consider whether this classification is appropriate based upon the available data. Here both clinical experience and relevant experimental data have been reviewed. Although there have been reports of an association between workplace exposure to ADCA and symptoms of respiratory allergy and occupational asthma, the evidence is less than persuasive, with in many instances a lack of properly controlled and executed diagnostic procedures...

A 33-year-old woman presented to our clinic for suspected photoallergic contact dermatitis with a recent episode of severe, vesicular dermatitis involving exposed skin and correlating with relocation to a new home. Biopsy results showed spongiotic and lichenoid dermatitis with eosinophils. Patch test results showed a very strong (+++) reaction to methylisothiazolinone (MI), mild (+) reaction to MI/methylchloroisothiazolinone, and no reaction to benzisothiazolinone. These allergens were found in several personal products...

In patients with COPD, there is controversy regarding the association of blood eosinophil (Eos) levels with 1) exacerbation frequency and 2) the effect of inhaled corticosteroids for prevention of exacerbations. To determine whether Eos define subgroups of patients exhibiting attributes of COPD clinical phenotypes, we compared clinical features and mortality rates in COPD patients from the Initiatives BPCO French cohort categorized using different thresholds of blood Eos levels. The following data were collected at inclusion: medical and smoking history, occupational exposures, dyspnea, cough and sputum production, exacerbations in the previous year, history of allergy and asthma, nasal symptoms, body mass index, St George Respiratory Questionnaire (SGRQ) total score, post-bronchodilator spirometry, comorbidities, and medications...

BACKGROUND: The relationship between atopic conditions and carcinoma of the skin has been described inconsistently. Population-based data providing information on atopic diseases as well as on skin cancer are sparse. OBJECTIVE: To determine the correlation between atopy and prevalence of precanceroses, non-melanoma skin cancer and malignant melanoma (MM), while taking into account known risk factors for skin cancer. METHODS: Data from occupational skin cancer screenings were analysed in a cross-sectional study...
