What Is a House Dust Allergy?
Some people start to sneeze or cough, get wet and itchy eyes or even symptoms of asthma (wheezing, cough, short breath, chest tightness) during vacuuming, dust cleaning, changing beds, shopping, or other activities where dust appears in the air.
Mechanism of house dust allergy. Some substances, like parts of dust mites or mold spores, when inhaled, trigger production of immunoglobulin E (IgE) antibodies in a sensitive person. On subsequent dust exposures, antibodies bind to mast cells in mucosa in eye conjunctiva, nose, throat, and bronchi, and trigger release of histamine from them. Histamine causes dilation of vessels in mucosa, and secretion of mucus from mucous glands, resulting in mucosal swelling and mucus secretion.
