Artificial stone silicosis: a UK case series

Area of Science:

• Occupational Medicine
• Pulmonary Medicine
• Toxicology

Background:

• Silicosis due to artificial stone (AS) has become a significant global health issue in the past decade.
• The increasing use of AS in construction and design contributes to rising occupational exposures.
• Early recognition and intervention are crucial for managing AS-related lung disease.

Purpose of the Study:

• To report the initial cases of silicosis linked to artificial stone exposure in the United Kingdom.
• To characterize the demographic, exposure, and clinical profiles of these patients.
• To emphasize the need for regulatory action and improved safety protocols.

Main Methods:

• Retrospective case series analysis of eight patients diagnosed with silicosis.
• Review of clinical presentations, occupational histories, and exposure durations.
• Assessment of disease severity and patient outcomes, including need for lung transplant.

Main Results:

• Eight male patients presented with silicosis, with a median age of 34 years.
• Median exposure to AS dust was 12.5 years, with four cases having 4-8 years of exposure.
• All cases involved dry cutting/polishing of AS worktops with insufficient safety measures; one patient died, and two required transplant evaluation.

Conclusions:

• Artificial stone silicosis is an emerging occupational hazard in the UK, affecting younger individuals with relatively short exposure durations.
• Clinical presentation can mimic other granulomatous lung diseases like sarcoidosis, necessitating high clinical suspicion.
• Urgent implementation of stricter safety regulations and proactive case identification strategies are imperative to mitigate this public health threat.
