Danger Dust

Purpose of review

There is a well established association between silica inhalational exposure and autoimmune disease, particularly in the context of intense exposure. We will provide in this article an update overview of new sources of silica dust exposure, with evidences of mechanisms from human and animal studies for association between silica and autoimmune diseases, their early detection of silicosis and new options for treatment.

The association between silica exposure and autoimmune disease was first described by Bramwell in 1914, who observed scleroderma among stone masons .

Fifty years later, Erasmus found an increased incidence of systemic sclerosis (SSc) among South African gold miners, later referred to as Erasmus syndrome .

In 1952, Caplan described the occurrence of multiple lung nodules in coal miners who suffered from rheumatoid arthritis (RA), comorbidity known as Caplan's syndrome or rheumatoid pneumoconiosis.

Significant risk of developing SSc, RA, systemic lupus erythematosus (SLE), dermatomyositis/polymyositis and antineutrophil cytoplasmic antibody-positive vasculitis has been linked to silica exposure and a study demonstrates that male patients with SSc have a high prevalence of occupational exposure to silica or solvents.
