Despite all efforts to prevent it, silicosis still afflicts tens of millions of workers in hazardous occupations and kills thousands of people every year, everywhere in the world. Silicosis mostly affects workers exposed to silica dust in occupations such mining, glass manufacturing, and foundry work. Moreover, cell therapy has yielded positive effects in models of lung fibrotic diseases such as asthma, COPD, and bleomycin-induced lung fibrosis [9294]. 107116, 2014. Please do not use SMS English, Short Text and Words like hi, hello. Symptoms may or may not be obvious; therefore, workers need to have a chest x-ray to determine if there is lung damage. D. S.

These properties make cell therapy an exceptionally advantageous therapeutic approach for fibrotic lung diseases, including silicosis. It is a progressive disease that causes symptoms like cough and shortness of breath. This problem is very widespread, and potentially worse than we currently know. This article was medically reviewed by Janice Litza, MD. . 9, no. Especially in someone otherwise young and healthy, a person might have undergone a lot of lung damage from silicosis before any obvious symptoms show up. The most extensively studied adult cell source for cell therapy is the bone marrow. Results from a clinical trial using mesenchymal stromal cells and a genetically modified culture of mesenchymal cells were recently published [53]. 163168, 2013.

Considering the wide range of cell therapy options, optimization of cell therapy protocols and advancements in clinical trials can lead to an important breakthrough for the management of the patients affected by this persistent disease. This, in turn, can limit how well you can breathe. As a last resource, lung transplantation is indicated to patients with no more pharmacological options. Silicosis is a lung disease caused by breathing in too much silica dust. Silicosis has a unique pathogenesis process, in which the phagocytosis and release of silica particles in the lung tissue drive the disease progression [20]. Many people find it helpful to connect with others dealing with silicosis. You can also talk to your doctor about whether adding essential oils or herbs will help. Lassance et al. Some medications might help you manage your disease. Exposure to silica dust is a health hazard for workers who manufacture, finish, and install natural and engineered stone countertop products. This review highlights the main mechanisms of action of silica dust in the alveolar environment and how cell therapy may help patients with silicosis by modulating the inflammation, reducing fibrosis, and, thus, improving lung function. The industrialization process steadily increased the occupational exposition of workers to breathable particles in many work environments. These results encouraged us to advance to a phase I clinical trial to test the safety of the autologous transplantation of bone marrow mononuclear cells in silicotic patients. Your lung function and the severity of the damage to your lungs will dictate whether or not you receive short-term or long-term oxygen treatment. This has been a race against the clock, since once scarring occurs it may be too late to remove the silica, Professor Chambers said. This usually happens in an occupational (job-related) setting. 4, Article ID e1001206, 2012. These might include: Bronchodilator medications like albuterol Cough medications like Robitussin (dextromethorphan) 9, no. A. Tsuda, F. S. Henry, and J. P.

Abreu et al., Protective effects of bone marrow mononuclear cell therapy on lung and heart in an elastase-induced emphysema model, Respiratory Physiology and Neurobiology, vol. 12, no. Only two registered clinical trials have been concluded in the past 10 years on silicosis treatments [53, 54], leaving a gap to be filled specially by developing countries, such as Brazil, India, and China, in which the prevalence of silicosis facilitates subject availability for clinical tests. The leukotriene B4 increases the amount of neutrophils in the inflammation site, and it is also involved in tumorigenesis [34]. This can cause severe symptoms of silicosis to appear in weeks or months.. W. W. Liu, H. X. Wang, W.

Castranova, From coal mine dust to quartz: mechanisms of pulmonary pathogenicity, Inhalation Toxicology, vol. Silica-induced lung damage occurs by five main mechanisms (Figure 1): (1) direct cytotoxicity, (2) generation of reactive species, (3) production of cytokines and chemokines, (4) fibrosis, and (5) cell death by apoptosis [2225]. Cell transplantation began to be thought as a possible treatment for multiple diseases, due to the potential of stem cells to differentiate, replacing damaged cells in target tissues. J. L. Kaw and S. H. Zaidi, Effect of ascorbic acid on pulmonary silicosis of guinea pigs, Archives of Environmental Health, vol. Macroscopically, nodules range in color from gray to black depending on the amount of associated carbonaceous dust or other black pigments incorporated . 32, pp. Chronic: The accumulated silica dust leads to swelling in the lungs and chest lymph nodes [5] . As there is no effective specific treatment of silicosis, the only way to protect workers' health is control of exposure to silica-containing dusts and to detect cases early through monitoring of currently and formerly exposed workers along with proper management to reduce disability. Sanja Jelic, MD, is board-certified in sleep medicine, critical care medicine, pulmonary disease, and internal medicine. Swap blasting material that contains silica for other types. T. A. Wynn and T.

Job activities posing risk, Silica exposure, silicosis, and the new occupational safety and health administration silica standard. Silicosis doesn't have one specific medical treatment. The disadvantages of the use of bone marrow mononuclear cells are the invasiveness of the procedureespecially considering that multiple doses may be required for sustained effectsand the variability of the constitution of the bone marrow. Rates in the United States have declined as better protective measures have been employed in many work environments. Silicosis is a chronic (long-term) lung disease caused by breathing in tiny particles of silicon dioxide in the form of free crystalline silica (quartz) or rarely by inhaling silicates, minerals containing silicon dioxide bound with other elements, such as talc. 4, pp. October 15, 2019.
