Title Byssinosis in carpet weavers exposed to wool contaminated with endotoxin
Bibliographic information July 1987, Vol.44, No.7, p.479-483. Illus. 17 ref.
Abstract 303 full-time day workers in a carpet-weaving factory were subjected to a physical examination, chest radiography, and vitalograph test, and answered a respiratory questionnaire. Fifty-four healthy, non-exposed subjects served as controls. Concentrations of dust and of bacterial endotoxin were measured. Of the workers, 259 (85.5%) had airway symptoms and 62 (20.5%) had maximum mid-expiratory flow (MMF) values of less than 60% compared to 9.2% of the controls. Symptoms in 68 workers (22%) were compatible with byssinosis and 36 of these underwent vitalography before starting work and after 4h work on Monday when significant reductions of their FEV1 and MMF were found. Twenty-one of these 36 workers were tested on Tuesday and no differences were found between measurements made before work started and 4h later. Airborne dust concentrations in the factory were high and bacterial endotoxin was found. Findings suggest that a large number of workers in the factory suffer from a disease indistinguishable from byssinosis even thogh wool is used almost exclusively, the only cotton being the wrap. The finding of endotoxin together with the absence of cotton confirms the theory that "byssinosis" is due to a bacterial endotoxin rather than to cotton itself.
