宜宾市肺结核对矽肺晋级和病死率影响的报告

目的　对宜宾市矽肺患者合并肺结核后,肺结核对矽肺患者晋级率、平均晋级时间及病死率影响的探讨。方法 采用回顾法,对宜宾市职业病诊断组1973～1998年检出的315例矽肺患者的原始资料进行分析、统计、处理。结果 Ⅰ期单纯矽肺与Ⅰ+T比较:晋级率分别为32.1%、56.3%(P<0.01);平均晋级时间分别为5.8年、4.3年(P<0.05);病死率分别为27.5%、66.7%(P<0.01);Ⅱ期单纯矽肺与Ⅱ+T比较:晋级率分别为19.6%、41.2%(P<0.01);平均晋级时间分别为4.9年、3.4年(P<0.05);病死率分别为51.1%、54.6%(P>0.05)。结论 矽肺患者合并肺结核后,使矽肺晋级率升高、平均晋级时间缩短、病死率增加。

The influence of thepulmonary tuberculosis on the grade-uplifting rate and mortality of silicosis in Yibin

Objective　To evaluate the influence of pulmonary tuberculosis on the grade-uplifting rate, average uplifting time and the death rate of silicosis complicated with pulmonary tuberculosis. Methods　Data of 315 cases of silicosis diagnosed by the Yibin Occapational Disease Department from 1973～1998 were studied、 analyzed and summed up. Results　The grade-uplifting rate of Ⅰ is 32.1%, while that of Ⅰ+T is 56.3%(P＜0.01); the average grade-uplifting time of Ⅰ is 5.8Y, while that of Ⅰ+T is 4.3Y (P＜0.05)； the death rate of Ⅰ is 27.5%, While that of Ⅰ+T is 66.7%(P＜0.01); the grade-uplifting rate of Ⅱ is 19.6%, while that of Ⅱ+T is 41.2%(P＜0.01); the average grade-uplifting time of Ⅱ is 4.9Y,while that of Ⅱ+T is 3.4Y( P＜0.05);the death rate of Ⅱ is 51.1%, while that of Ⅱ+T is 54.6%(P＞0.05). Conclusion　All this shows that silicosis complicated with pulmonary tuberculosis increases the grade-uplifting rate, shortens the averge grade-uplifting time and increases the death rate.
