[2] [3] [8] AERD is uncommon among children, with around 6% of patients, predominantly female, reporting disease onset during childhood. [9]
Nitrogen dioxide poisoning may alter macrophage activity and immune function leading to susceptibility of the body to a wide range of infections, and overexposure to the gas may also lead to methemoglobinemia, a disorder characterized by a higher than normal level of methemoglobin (metHb, i.e., ferric [Fe 3+] rather than ferrous [Fe 2 ...
