Objective: To determine the agents causing asthmatic reactions during specific inhalation challenges (SICs) in workers with cleaning-related asthma symptoms and to assess the pattern of bronchial responses in order to identify the mechanisms involved in cleaning-related asthma.
Design: A retrospective case series analysis.
Setting: The study included all participants who completed an SIC procedure with the cleaning/disinfection products suspected of causing work-related asthma over the period 1992-2011 in a tertiary centre, which is the single specialised centre of the French-speaking part of Belgium where all participants with work-related asthma are referred to for SIC.
Background: Soluble mesothelin (SM) and megakaryocyte potentiating factor (MPF) are serum biomarkers of mesothelioma. This study examined the effect of clinical covariates on biomarkers levels and their diagnostic and prognostic value.
Methods: Five hundred ninety-four participants were enrolled in a multicenter study, including 106 patients with mesothelioma and 488 control subjects.
Objectives: There is little information on the changes in the pattern of occupational asthma (OA) over time. The objective of this study was to evaluate the time trends in the incidence and causes of immunological OA in Belgium using workers' compensation data.
Methods: Cases of OA were identified through a retrospective review of all claims submitted by salaried workers to the Belgian Workers' Compensation Board from 1993 to 2002.
Introduction: Soluble mesothelin (SM) and megakaryocyte potentiating factor (MPF) are serum biomarkers of mesothelioma. This study aims to examine the longitudinal behavior of SM and MPF in controls to gain insight in the optimal use of these biomarkers in screening.
Methods: Asbestos-exposed individuals, with no malignant disease at inclusion, were surveilled for 2 years with annual measurements of SM and MPF.
Rationale: Soluble mesothelin (SM) is currently the reference serum biomarker of malignant pleural mesothelioma (MPM). Megakaryocyte potentiating factor (MPF), which originates from the same precursor protein, is potentially more sensitive, yet lacks validation.
Objectives: To analyze the diagnostic performance of MPF as an MPM biomarker and compare this performance with SM.
Objectives: This study aimed at characterizing the nature, severity, and timing of nasal and ocular symptoms in subjects with work-exacerbated asthma (WEA).
Methods: Among the 363 subjects referred to a tertiary-care hospital for the investigation of work-related asthma symptoms, 105 subjects who demonstrated non-specific bronchial hyperresponsiveness to histamine, but a negative response to a specific inhalation challenge with the suspected occupational agent(s) were considered as having WEA. Their characteristics were compared with those of 172 subjects with occupational asthma (OA), ascertained by a positive response to a specific inhalation challenge.
