Stachybotrys chartarum: current knowledge of its role in disease
1Veterans Administration Medical Center, Portland, Oregon, USA. sudakind@ohsu.edu
Abstract:
Stachybotrys chartarum is one of several species of filamentous fungi capable of producing mycotoxins under certain environmental conditions. In some observational studies, the growth of this toxigenic mold in the indoor environment has been implicated as a cause of building-related illness. Following reports of a cluster of cases of pulmonary hemosiderosis and hemorrhage associated with exposure to Stachybotrys, public health measures have been recommended which have far-reaching implications. Although the hazards associated with exposure to some mycotoxins have been well studied, the health risks from environmental exposure to Stachybotrys remain poorly defined. The purpose of this review is to critically evaluate the current body of epidemiologic knowledge regarding Stachybotrys and to increase physician awareness regarding this emerging environmental health issue.
Insights
Stachybotrys chartarum, a toxigenic mold, is linked to building-related illnesses. Further research is needed to define health risks from indoor environmental exposure to this fungus.
Area of Science:
- Environmental Science
- Mycology
- Public Health
Background:
- Stachybotrys chartarum is a filamentous fungus producing mycotoxins.
- Indoor growth of this toxigenic mold has been linked to building-related illnesses.
- Concerns exist regarding pulmonary hemosiderosis and hemorrhage potentially associated with Stachybotrys exposure.
Purpose of the Study:
- To critically evaluate the epidemiologic knowledge on Stachybotrys.
- To raise physician awareness of Stachybotrys as an emerging environmental health issue.
Main Methods:
- Literature review of epidemiologic studies.
- Critical evaluation of existing data on Stachybotrys and health effects.
Main Results:
- Health risks from environmental Stachybotrys exposure are poorly defined.
- Existing studies suggest a potential link between Stachybotrys and adverse health outcomes.
- Further research is necessary to establish definitive causal relationships.
Conclusions:
- The health implications of indoor Stachybotrys exposure require further investigation.
- Physicians should be aware of the potential risks associated with this environmental mold.
- Clearer guidelines are needed for managing Stachybotrys in indoor environments.
