Abstract
In order to understand senile pulmonary tuberculosis （PTB） and increase diagnostic and treating efficiency, clinical features of 816 senile PTB patients and 350 young PTB patients from our out patient department from 2002 to 2010 were compared. The comparison included age, sex, disease course, clinical symptoms, first or second treated, PTB classification, sputum positivity, complications, treatment and outcomes. The results showed that the number of male patients is greater than that of female patients in both groups. Among patients, who is treated with short course （≤one month） and are confirmatively diagnosed within six month, there is significantly difference between elder （30.64 %）and young group （81%）. Senile PTB patients usually have more than three symptoms while young patients＇ symptoms are fewer and typical. The proportion of first and second treated is 53.92% and 46.08% in senile PTB group; 80. 86% and 19. 14% in young PTB group. Elder group is higher than young group in rate of chronic fibrotic cavity formation （25.73% vs. 16.57% ）, sputum positive （39.95% vs. 28.86%） and complications （58.82% vs. 16%）. However, elder group is lower than young group in cure rate （75. 74% vs. 88.86%） and recovery rate （11.76% vs. 3.43%）. Therefore, senile PTB is an important source of infection.关键词
