Silicosis, a fibrotic lung disease caused by crystalline silica inhalation, presents unique challenges in lung transplantation. This case reports an unprecedented complication in a lung transplant recipient with chronic silicosis. A man in his 60 s, post left single-lung transplantation for silica-induced pneumoconiosis, developed acute respiratory deterioration following routine bronchoscopy.

Pulmonary and systemic effects of inhaled crystalline silica in the HOCl-induced mouse model of systemic sclerosis: An experimental model of Erasmus syndrome.

Occupational exposure to crystalline silica is etiologically linked to an increased incidence of systemic sclerosis (SSc), also called Erasmus syndrome. The underlying mechanisms of silica-related SSc are still poorly understood. We demonstrated that early and repeated silica exposure contribute to the severity of SSc symptoms in the hypochloric acid (HOCl)-induced SSc mouse model.

Inflammatory biomarkers in workers exposed to silica dust: integrative review.

Rev Bras Med Trab

November 2024

Escola Nacional de Saúde Pública Sérgio Arouca, Fundação Oswaldo Cruz (Fiocruz), Rio de Janeiro, RJ, Brazil.

Introduction: Silicosis is a severe, progressive, fibrosing lung disease caused by the inhalation of free crystalline silica dust; it is the most prevalent pneumoconiosis worldwide. It is associated with a chronic inflammatory process triggered by silica particles in the pulmonary alveoli. Alveolar macrophages play a key role in the pathogenesis of silicosis, with additional contributions from polymorphonuclear cells, epithelial cells, and the release of inflammatory mediators.

Systemic sclerosis (SSc) is a chronic orphan autoimmune disease with the highest mortality rate among rheumatic diseases. SSc-related interstitial-lung disease (ILD) remains among the leading causes of SSc-related mortality with still few therapeutic effective strategies. In patients with crystallin silica exposure, SSc is recognized as an occupational disease according to the French social security system (Table 25A of the general insurance regimen).

Pathologic Findings in Severe Coal Workers' Pneumoconiosis in Contemporary US Coal Miners.

Arch Pathol Lab Med

July 2024

the Department of Environmental and Occupational Health Sciences, School of Public Health, University of Illinois Chicago, Chicago (Almberg, Iwaniuk, Go, Cohen).

Context.—: The pathology of coal workers' pneumoconiosis (CWP) and its most severe form-progressive massive fibrosis (PMF)-in US coal miners has changed in recent years. Severe disease is occurring in younger miners and has been linked to an increase in silica dust exposure.
