First case of acute respiratory distress syndrome and alimentary tract hemorrhage following mass ingestion of methylisothiazolinone

AbstractThe frequency of methylisothiazolinone (MIT)-related health concerns regarding allergic contact dermatitis with a spongiotic reaction pattern and restrictive lung function indicating peripheral airway dysfunction caused by the use of humidifier disinfectant is increasingly rising. There is a limited number of evidences supporting the environmentally acute and mass exposure to MIT resulting in acute respiratory distress syndrome (ARDS). Here, we report the first case of ARDS and alimentary tract hemorrhage following mass ingestion of methylisothiazolinone.
