Pneumoconiosis patients show declining lung function and increased inflammation markers over time. Radiological progression is linked to a more significant decrease in carbon monoxide diffusing capacity (DLCO).
Area of Science:
- Occupational Medicine
- Pulmonary Medicine
- Radiology
Background:
- Pneumoconiosis remains a significant occupational health issue despite medical advancements.
- Understanding disease progression requires monitoring pulmonary function and inflammatory markers.
Purpose of the Study:
- To analyze changes in pulmonary function tests and systemic inflammation in pneumoconiosis patients.
- To correlate these changes with radiological progression during follow-up.
Main Methods:
- Retrospective cohort study of 109 pneumoconiosis patients (2007-2024).
- Analysis of spirometry, DLCO, ILO pneumoconiosis categories, and hemogram parameters.
- Assessment of associations using non-parametric and regression analyses.
Main Results:
- Radiological progression observed in 20.2% of patients, increasing with disease category.
- Significant annual decline in FEV₁ and FEV₁/FVC noted.
- DLCO decline was more pronounced in patients with radiological progression; inflammatory markers increased.
Conclusions:
- Pneumoconiosis patients experience pulmonary function decline and altered inflammatory markers.
- Radiological progression correlates with greater DLCO reduction, emphasizing integrated assessment.
- Further prospective studies are recommended to clarify clinical significance.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
