Asthma molds causing

In further pursuit of a train of observations which eventually relates fungi to pulmonary problems and suggests possible involvement in byssinosis, we note that most physicians concerned with asthma believe that fungus or "mold" spores in out-door air can cause asthmatic attacks in some persons with asthmatic tendencies. Two of the fungi which they cite most frequently as... 

The causes may include household dust, droppings from dust mites, and mold. Asthma-related illness resulted in over 100,000 children visiting a hospital and losing over 10 million school days. A very different kind of long-term disability results from childhood lead exposure. The US Centers of Disease Control estimated that over one million US children have elevated blood lead levels due to household exposures. 

One in 10 persons, 22 million people, in the United States have allergies. Ten million of these suffer from the nasal discomfort of "hay fever" and six million from die more serious asthma. Substantial numbers of people in the United States die of allergic reactions to insect stings (more than 30 per year) or to injections of penicillin (300 per year in 1970). Foods, drugs, pollens, mold spores, mites in house dust, and even heat or cold can evoke serious allergic reactions. Among these eczema (atopic dermatitis) is very common. A major cause of allergic reactions has been... 

As a general rule, we don t recommend air filters because the air they produce is never as pure as outdoor air, even in the city. If for some reason you can t ventilate a room, or you ve tested and find that, despite your best efforts, pollutants remain, here are some things to consider First of all, what do you need to filter, and how much money are you willing to spend to get the job done There are two types of pollutants, particulates (which include dust, mold, pollen, soot, smoke, and dander) and gases (VOCs from paint, plastics, and solvents). Air purifiers can t do much for gaseous pollutants, but they will get rid of particulates, which cause asthma and allergies. 

The most common form of asthma is allergic asthma (atopic or extrinsic asthma), and it is associated with environmental allergens, such as plant pollens, house dust mites (Dermatophagoides farinae), domestic pet dander, molds, and foods. The less common form, intrinsic asthma, has no known allergic cause and usually occurs in adults older than 35 years. Intrinsic asthma may result from an autonomic dysfunction characterized by excess cholinergic... 

There is no association between atopy and ODTS (Manfreda et al. 1986). The moldy material that causes ODTS gives rise to dense clouds of dust. One would expect that subjects with atopy and allergic asthma would not be affected by ODTS. Because of bronchial hyperresponsiveness, they probably can t stand the high levels of mold dust required to induce ODTS.
