PARADA C, MARÍA TERESA et al. Lung transplantation in silicosis. Rev. chil. enferm. respir. [online]. 2007, vol.23, n.2, pp.99-105. ISSN 0717-7348.  http://dx.doi.org/10.4067/S0717-73482007000200004.

Silicosis is a prevalent disease in Chile, a developing miner country. Scarce information about lung transplantation as an alternative for treating severe silicosis is available. Objective: To describe the time and way of exposure to silica and the clinical characteristics of silicotic patients subjected to lung transplantation at Clinica Las Condes, Santiago. Patients and Methods: From 38 patients subjected to lung transplantation between 1999 and 2006, four of them were transplanted because of severe silicosis. Ldiopathic pulmonary fibrosis was the predominant underlying disease (55%) of these 38 patients. Results: The four silicotic patients were transplanted at an age ranging from 34 to 65 years old. Their period of exposure ranged between 5 and 30 years and symptoms become evident after 4 to 30 years of exposure. Two patients were miners, another one was a quartz grinding worker and the fourth of them was a polisher of dental prothesis, The surgery was complex because of distortion in pulmonary anatomy. The hospital length of stay was longer in silicotics as compared with non-silicotic patients with lung transplant (41 versus 21 days, p < 0.10; c2). The long-term clinical course has been satisfactory. Association with tuberculosis has not been shown in any of these patients, Conclusions: Lung transplant is an alternative in patients with severe silicosis. Pulmonary anatomy is distorted in these patients determining more perioperatory morbidity than in non-silicotic patients
