Do bullae and emphysema increase risk of pneumothorax in silicosis?

The association between single nucleotide polymorphisms (SNPs) in the interleukin (IL)-17 gene and silicosis has been evaluated in different populations. The aim of the present study was to analyze the association between SNPs at IL-17A (-832A/G) and IL-17F (+7488A/G) and susceptibility to accelerated silicosis in the Iranian Kurdish population. We studied 48 patients with accelerated silicosis and 62 controls. Genomic DNA was isolated using the "salting out" method. PCR-RFLP was performed for all SNPs typing. The frequencies of A/A, A/G, and G/G genotypes at IL-17A (-832A/G) were 4 (8.33%), 23 (47.92%), and 21 (43.75%) in patients and 5 (8.06%), 35 (56.45%), and 22 (35.48%) in controls, respectively. The frequencies of A and G alleles at IL-17 (-832A/G) were 31 (32.29%) and 65 (67.71%) in patients, and 45 (36.29%) and 79 (63.71%) in the controls, respectively. The frequencies of A/A, A/G, and G/G genotypes at IL-17F (+7488A/G) were 1 (2.08%), 47 (97.92%), and 0 (0%) in patients, and 11 (17.74%), 51 (82.26%), and 0 (0%) in the controls, respectively. The frequencies of A and G alleles at IL-17F (+7488A/G) were 49 (51.04%) and 47 (48.96%) in patients, and 73 (58.87%) and 51 (41.13%) in the controls, respectively. IL-17F (+7488A/G) genotype was more frequent among the cases compared with controls (97.92% vs. 82.26%). The frequency of the IL-17F (+7488A/G) genotype was significantly greater in patients with accelerated silicosis (odds ratio = 10.13 95%; confidence interval = 1.2-81.5; p = 0.008). The IL-17F (+7488A/G) genotype revealed a significantly increased risk of accelerated silicosis ( p < 0.05). The IL-17F (+7488 G) allele was associated with an increased risk of accelerated silicosis, but in the case of the IL-17A (-832A/G) polymorphism, a significant association was not observed.

Background: Silicosis is a fibrosis in the lung caused by inhalation, retention, and reaction to crystalline silica. The prevalence rate is potentially increasing throughout the world. Cases of bilateral spontaneous pneumothorax and transaminitis due to complications of silicosis are very rare. In this case, the patient was presented with bilateral secondary spontaneous pneumothorax as well as in the development of the diagnosis of silicosis, liver dysfunction, and pneumonia. Case: A 36-year-old male was admited to hospital with shortness of breath, the patient was once stone artisans for 7 years, rarely using PPE. Bilateral pneumothorax was established based on the results of clinical and radiological examinations. HRCT showed that it supported silicosis, left fluidopneumothorax, and right pneumothorax. Bronchoscopy was not possible due to the incompatible conditions and subsequently the patient was examined for silica levels from both plueral fluid with significant pleural silica. Summary: Diagnosis of pulmonary silicosis was done by clinical, radiological, and silica analysis of bronchial rinses, but certain conditions of silica could be found from pleural fluid. Silicosis therapy with complications until recently is only symptomatic, definitive therapy has not been found. Silicosis complications can be from pneumothorax bilateral (rarely), tuberculosis, transaminitis, and pneumonia. Conclusion: Pulmonary silicosis can be found from pleural fluid when the amount is large enough, fibrosis and extensive lung damage occurred. Silicosis can have an impact on pneumothorax, liver disorders, pneumonia, tuberculosis, and respiratory problems.
