Silica exposure is a recognized risk factor for fibrotic, inflammatory, and cancerous respiratory diseases. Currently, no specific biological marker exists. The hypothesis is that AACD146 reflects early effects of silica exposure. The study will include 110 participants divided into two groups (exposed vs. non-exposed) and will compare AACD146 prevalence according to exposure level and the presence of respiratory diseases.",[54,55],"Exposure Occupational","Pulmonary Diseases",[57,58,59],"silica","Exposure occupational","Pulmonary diseases","NOT_YET_RECRUITING","2026-01-29",{"date":63,"type":64},"2026-02-02","ACTUAL",{"date":66,"type":48},"2026-06",{"date":68,"type":48},"2028-06",{"name":5,"class":6}]
