Determinants of the bronchial response to high molecular weight occupational agents in a dry aerosol form.
In occupational challenge tests with isocyanate vapours, bronchial responsiveness is determined by the total dose rather than the concentration or duration of exposure. Whether the same applies for high molecular weight (HMW) agents in powder form is unknown. The aim of this study was to determine whether the total dose of HMW agents in powder form is responsible for the immediate reaction docu...
متن کاملOccupational exposure to high molecular weight allergens and lymphoma risk among Italian adults.
OBJECTIVES Exposure to high molecular weight (HMW) allergens that provoke immune reactivity through an IgE-mediated pathway has been associated with a decreased risk of B-cell lymphoma. The present analysis was conducted to assess the associations between occupational exposure to specific HMW allergens and the risk of B-cell, T-cell, and Hodgkin's lymphomas. METHODS We analyzed data from 2,29...
متن کاملComparative Airway Response to High- vs Low-Molecular Weight Agents in Occupational Asthma Running title: Bronchial responses to occupational agents Authors:
Airway responses to occupational agents in sensitized workers may vary, clinically and physiologically. We compared the patterns of change in airway responsiveness, type of response, and fall in expiratory flows following laboratory exposure to high or low molecular weight agents in sensitized workers. Data on workers who underwent specific inhalation challenges with occupational sensitizers (1...
متن کاملImmune Responses to Inhalant Allergens
This overview describes the nature of the immune responses induced by the inhalation of allergens. There is a dichotomy in that B cells have multiple mechanisms that limit the amount of immunoglobulin E (IgE) antibody production, whereas T-cell responses are large even in nonallergic subjects. With the possible exception of responses to cat allergen, however, T cells from nonallergic subjects h...
متن کاملComparative airway response to high- versus low-molecular weight agents in occupational asthma.
Airway responses to occupational agents in sensitised workers may vary clinically and physiologically. The patterns of change in airway responsiveness, type of response and fall in expiratory flows following laboratory exposure to high- or low-molecular weight agents (HMW and LMW agents, respectively) were compared in sensitised workers. Data on workers who underwent specific inhalation challen...
