OBJECTIVE To assess whether the severity of asthma is associated with sensitisation to airborne moulds rather than to other seasonal or perennial allergens. DESIGN Multicentre epidemiological survey in 30 centres. SETTING European Community respiratory health survey. PARTICIPANTS 1132 adults aged 20-44 years with current asthma and with skin prick test results. MAIN OUTCOME MEASURES Sev...
Lupin is part of the Mediterranean diet and is also used as a thickener of food products. It has been recognised as a cause of serious allergic reactions. This study aims at determining the prevalence of lupin sensitisation in 1,160 subjects consulting allergologists. This population performed skin prick tests (SPT) to lupin. In case of positivity, a clinical questionnaire was applied and the s...
Stress is known to modulate sensitisation to repeated psychostimulant exposure. However, there is no direct evidence linking glucocorticoids and sensitisation achieved by repeated administration of the NMDA receptor antagonist MK-801. We tested the hypothesis that co-administration of RU486, a glucocorticoid receptor (GR) antagonist, prior to repeated daily MK-801 injections would block the exp...
The objective of the present study was to investigate the contribution of adrenal stress hormones to strain differences in cocaine sensitivity. For this purpose, we have studied sensitisation to the locomotor stimulant effect of cocaine and, in parallel, cocaine-induced corticosterone secretion in two inbred mouse strains: C57BL/6 and DBA/2. Adrenalectomy ('ADX': surgical removal of the adrenal...
debosch, South Africa; University of Cape Town, Cape Town, South Africa; School of Paediatrics and Child Health, University of Western Australia, Perth, Australia; Division of Allergy, University of Cape Town, Cape Town, South Africa. Background: The relationship between sensitisation to helminths and atopy, bronchial-hyperresponsiveness and allergic diseases may differ depending on many factor...
AIMS The farming environment in childhood has been reported to decrease the risk of sensitisation to allergens. The purpose of the present study was to explore whether later exposure to a farming environment also could affect this sensitisation. METHODS A population based sample of 202 women who did not live on a farm and 231 who did. The subjects filled in a questionnaire and underwent skin ...
BACKGROUND AND AIMS Longstanding ulcerative colitis (UC), especially in the presence of epithelial dysplasia, is associated with an increased risk of developing cancer. As dysplasia is not visible during routine endoscopy, at least 40-50 random biopsies in four quadrants every 10 cm are recommended. Fluorescence endoscopy after sensitisation with 5-aminolaevulinic acid (5-ALA) was assessed for ...
BACKGROUND A positive association between IgE sensitisation and exhaled NO levels has been found in several studies, but there are no reports on the compartment of the lung that is responsible for the increase in exhaled NO levels seen in IgE-sensitised subjects. METHODS The present study comprised 288 adult subjects from the European Community Respiratory Health Survey II who were investigat...
BACKGROUND A few reports demonstrate the occurrence of egg allergy in adolescent and adult patients suffering from atopic dermatitis and the association of this allergy to other food and aeroallergens. AIMS AND OBJECTIVES The aim of this study is to evaluate the occurrence of egg allergy in patients suffering from atopic dermatitis at the age 14 years and older and to evaluate the relationshi...
BACKGROUND The micro-array techniques for the detection of specific IgE has improved the diagnostic procedures for allergic diseases. This method also allows to define sensitisation profiles from an epidemiological point of view. We studied the sensitisation pattern in a population of polysensitized patients with respiratory allergy, living in a restricted geographical area in the north-west It...
