Dimethylacetamide-induced occupational toxic hepatitis with a short term recurrence: a rare case report

DMAc (CAS NO. 127-19-5) is one of the important organic solvents in chemical industry (1). In China, it is mainly used in the wet process of acrylic fiber production, especially during spandex spinning (2). It could also be applied for extracting butadiene from ethylene pyrolysis gas as well as the production of polyimide film (3). Reportedly, DMAc could be inhaled or absorbed through the skin leading to occupational damage with liver as the mainly susceptible organ (4,5). Here, we report a case of hepatotoxicity due to DMAc exposure, who recovered after treatment but relapsed as soon as coming back to work
