Title Incidence of dimethylacetamide induced hepatic injury among new employees in a cohort of elastane fibre workers
Bibliographic information Oct. 2006, Vol.63, No.10, p.688-693. Illus. 16 ref.
Abstract The objective of this cohort was to investigate the incidence of N,N-dimethylacetamide (DMA)-induced hepatic injury among new elastane fibre workers and to explore risk factors relating to this injury. A total of 440 new workers employed from 1 January 2002 to 31 July 2004 were included as study subjects. DMA exposure estimates were based on urinary N-methylacetamide (NMA) concentrations. There were 28 cases of DMA-induced hepatic injury. The overall incidence of DMA induced hepatic injury among new elastane fibre workers was 0.089/person-year. Incidence rates were seven to ten times higher in high exposure groups than in low exposure groups. Results suggest the existence of a dose-dependent DMA-induced hepatic injury. The inverse relation between the incidence of DMA-induced hepatic injury and duration of employment may reflect a type of healthy worker effect or an acquired tolerance to DMA-induced hepatic injury.
