The aim of the study was to evaluate the plasma levels of inflammatory mediators in subjects exposed to silica, with and without silicosis compared with unexposed control group; and to check the association between inflammatory mediators with pulmonary function, quality of life, functional capacity, and dyspnea grade.
Inflammatory mediators were measured by enzyme-linked immunosorbent assay. There were 30 subjects exposed to silica and 24 control group.
Interleukin-6 plasma levels were higher in subjects exposed to silica with and without silicosis than in the control group. There was a positive correlation between radiological severity and the quality of life, whereas there was a negative correlation between radiological severity and pulmonary function. A negative correlation between sTNFR1 plasma level and functional capacity was found. Interleukin-10 was negatively correlated with the quality of life total score and was positively correlated with the functional capacity and pulmonary function.
本研究旨在评估接触二氧化硅的受试者（有矽肺和无矽肺）与未接触的对照组相比的炎症介质血浆水平；并检查炎症介质与肺功能、生活质量、功能能力和呼吸困难分级之间的关联。
通过酶联免疫吸附测定法测量炎症介质。有30名接触二氧化硅的受试者和24名对照组。
有矽肺和无矽肺的接触二氧化硅受试者的白细胞介素-6血浆水平高于对照组。放射学严重程度与生活质量呈正相关，而放射学严重程度与肺功能呈负相关。发现可溶性肿瘤坏死因子受体1（sTNFR1）血浆水平与功能能力呈负相关。白细胞介素-10与生活质量总分呈负相关，与功能能力和肺功能呈正相关。
