Occupational and Environmental Exposures in Lupus and Systemic Sclerosis

October 11, 2010

Diverse mechanisms of pathogenesis have been proposed for the autoimmune diseases. A growing body of medical literature suggests a potential effect of occupational exposures on their development.

What role do occupational exposures play in RA?

February 27, 2008

Occupational exposure to various chemicals, minerals, and toxins may increase the risk of rheumatoid arthritis (RA). Relationships between silica exposure and lung, renal, and autoimmune disease have been observed. Although a relationship between silica exposure and RA has been identified, it is not well defined. The evidence indicating that cigarette smoking is an independent risk factor for RA is conclusive. Agents that may be capable of inducing experimental arthritis in animals include adjuvants from bacteria, yeast, viruses, and mineral oils. In a Swedish study, exposure to any mineral oil was associated with a 30% increased relative risk of RA. (J Musculoskel Med. 2008;25:130-136)
