Asbestos exposure and autoantibody titers: Eunsoo Lee, Youngki Kim, Se Yeong Kim, Dongmug Kang; Ann Occup Environ Med 2020;32:e32. Published online September 1, 2020; DOI: https://doi.org/10.35371/aoem.2020.32.e32

Background

Asbestos is a well-known hazardous substance that causes occupational and environmental diseases including asbestosis (lung fibrosis). Silica exposure which causes silicosis (another type of lung fibrosis) has long been linked to the development of autoimmune diseases; however, there are few studies on the relationship between asbestos exposure and autoimmune diseases.

Methods

A total of 54 individuals who had worked in a former asbestos textile factory underwent autoantibody-related blood tests, chest X-ray imaging, and pulmonary function tests. Based on the job exposure matrix (JEM), the estimated asbestos exposure concentrations were determined, and the presence of asbestosis was determined by chest radiography.

Results

Scleroderma (Scl-70) and ribonucleoprotein (RNP) antibodies were significantly lowered in the pleural plaque present group than in the absent group. Additionally, Scl-70, RNP, and Sjögren's syndrome type B (SS-B) antibodies were significantly lowered in the asbestosis present group. When stratifying variables with or without asbestosis, Scl-70, Smith, SS-B, and RNP antibodies decreased in female, crocidolite handling group, and higher estimated asbestos exposure level group.

Conclusions

Contrary to our expectations that autoantibody titers would be higher in groups with high asbestos exposure or in the asbestosis group, those with asbestosis showed lower titers. But as our research has some methodological limitations, the lowered titer of autoimmune antibody in our asbestos exposed subjects could not be simply interpreted as a lowered risk of autoimmune diseases. So careful interpreting should be taken when examine autoantibodies to screening or diagnose autoimmune diseases in people with asbestos exposure. In addition, it is necessary to establish relevance of asbestosis and autoantibodies through further studies of larger scale and higher confidence levels.

Background

The International Agency for Research on Cancer classifies asbestos as belonging to Carcinogen Group 2A for gastric cancer. We herein report a case of gastric cancer associated with asbestosis and describe the work-related and risk assessments of asbestos exposure for gastric cancer.

Case presentation

The 66-year-old male patient in our case worked in asbestos spinning factories. His level of cumulated asbestos fiber exposure was estimated to be 38.0–71.0 f-yr/cc. Thus, the Excess Life Cancer Risk for lung cancer associated with asbestos exposure was 9,648×10⁻⁵, almost 9,600 times the value recommended by the United States of America Environmental Protection Agency (1 × 10⁻⁵). The relative risk of developing lung cancer for this patient was more than 25 f-yr/cc, a well-known criterion for doubling the risk of lung cancer.

Conclusion

The patient’s exposure to high-dose asbestos was sufficient to increase his risk of gastric cancer because as the risk of lung cancer increased, the risk of gastric cancer was due to increase as well. Therefore, occupational asbestos fiber exposure might be associated with gastric cancer in this case.

A Case Study of a Foundry Worker with Localized Asbestosis: an Uncommon Occurrence in Korea: Tae Woo Kim, Dong Hee Koh, Min Gi Kim, Seung Won Yoo, Hyang Woo Ryu, Jeong Hee Han, Soon Hee Jung; Korean Journal of Occupational and Environmental Medicine 2009;21(2):201-208. Published online June 30, 2009; DOI: https://doi.org/10.35371/kjoem.2009.21.2.201

Abstract PDF

BACKGROUND
Foundry workers are known to be exposed to silica and have an increased risk of silicosis. There are also reports that state these foundry workers were associated with asbestos-related change in the X-ray results of the lungs. This report discusses a case of localized asbestosis developed in a foundry worker who worked in 12 Korean foundries.
CASE
REPORT: A 49-year-old man who worked at molding and melting for 30 years, presented with sore throat, cough and yellow sputum for 1 month. From physical and clinical examination, pulmonary tuberculosis was highly suspicious; therefore, he was medicated for 6 months. After tuberculosis medication, the radiological finding was reactivation of tuberculosis, and an asbestos body was detected at a transbronchial lung biopsy. During an operation, operators found multiple palpable masses and bullae localized in the right upper lobe (RUL) and performed right upper lobectomy and right middle lobe wedge resection. Using hematoxylin-eosin stain and iron stain, we could detect asbestos bodies by light microscopy. We analyzed the asbestos fiber burden in dry lung tissue by transmission electron microscopy with energy dispersive X-ray spectrometer (TEM-EDX). The fiber type was chrysotile and the fiber burden was 23.26x106 fiber/g dry lung.
DISCUSSION
This case study of a foundry worker with localized asbestosis is uncommon in Korea. We found an occupational relationship between the foundry worker and localized asbestosis through various investigative techniques such as measurements taken at his working environment, clinical, radiological and pathological examination of the foundry worker and mineralogical examination of the asbestos fiber.

A case of asbestosis: Young Su Lee, Tae Won Jang, Ho Dae Yu, Maan Hong Jung, Yong Hwan Lee, Ji Young Suh, Bang Hur, Jae Sung Lee; Korean Journal of Occupational and Environmental Medicine 1999;11(1):119-124. Published online March 31, 1999; DOI: https://doi.org/10.35371/kjoem.1999.11.1.119

Abstract PDF: Asbestosis is the disease of pulmonary fibrosis caused by the inhaled asbestos fibers, and could be diagnosed clinically, in the case of exposure history to asbestos is proved, by clinical symptoms of dyspnea or dry cough, physical examination findings, and the radiographic features. But many other inorganic dusts would show similar findings in the chest radiogram and sometimes the exposure history is obscure, so for the exact diagnosis of asbestosis lung biopsy is needed. In Korea, there have been some reports of survey in the workplace where asbestos is handled or of asbestos related diseases. This is a case report of asbestosis with accompanying pleural plaques, who had the occupational exposure to asbestos for 30 years and the consistent clinical, radiographic and pathological findings in the lung tissue obtained by the videoscope assisted thoracoscopic biopsy(VATS).

Prevalence of Asbestosis in Korean Asbestos Industry: Do myung Paek, Nam Won Paik, Jung Deun Choi, Mi A Son, Jung Gi Im, Won Jin Lee, Young Hahn Moon, Jung Sun Park, Byung Soon Choi; Korean Journal of Occupational and Environmental Medicine 1995;7(1):46-57.

Abstract PDF

Asbestos industry has been in operation over 60 years in Korea. However, the prevalence of asbestosis has not been yet reported. With rapid turn-over of workers, previous cross-sectional studies of current workers on the job could not find cases with exposures long enough for the development of asbestosis. This study was done to evaluate asbestosis prevalence of those worksites with operation history of more than 20 years. In total, 139 workers from 5 worksites were examined. Asbestos industries covered in the study include 2 asbestos textile, 1 brake lining, and 2 ship repairing worksites. Chest x-ray was taken from all workers and read by two exports familiar with pneumoconiosis classification according to 1980 ILO guidelines. Those with findings compatible with asbestosis were further checked with high resolution computerized tomography (HRCT). Pulmonary function tests were done according to ATS guidelines, and occupational and previous medical history was taken through a standardized interview. Air-borne asbestos was measured according to NI0SH method 7400. The air-borno asbestos concentrations ranged from 0.2-1.3 f/cc for asbestos textile, from 0.7~l.0 f/cc for brake lining, and from 6.3-7.8 f/cc during asbestos removal at ship repairing worksite. Of the 139 workers 25 had abnormal chest radiographic findings, and 10 of them had findings compatible with pneumoconiosis. When work history and current asbestos measurements were accounted, 9 workers who had more than 10 years of asbestos exposure history showed chest radiographic findings of pneumoconiosis with Finally, 4 workers showed finding of pulmonary fibrosis and/or pleural thickening at HRCT, and 2 of them had restrictive lung function changes. The study results showed that, among 139 sutjects, there were 4 (3%) definite asbeatosis cases confirmed with HRCT. The prevalence of probable asbestosis was 7% for 10-14 years of exposure, 13% for 15-19 years of exposure, and 23% for 20 or more years of exposure. The prevalence of compensable asbestosis with abnormal lung function was 4-6% for those with 15 or more years of exposure.
